ABSTRACT

El adenocarcinoma pancreático ductal (APD) es la cuarta causa de muerte por cáncer y se proyecta que para el 2030 ocupe el segundo lugar. El pronóstico es sombrío, siendo la sobrevida menor a 9% en 5 años. Se consideró durante mucho tiempo a la resección quirúrgica como el único tratamiento curativo, sin embargo, sólo el 15 a 20% de los pacientes pueden ser beneficiados con la misma. La clasificación pre terapéutica más utilizada es la del National Comprehensive Cáncer Network (NCCN), basada en la relación del tumor con estructuras vasculares, clasificándolos en tumores "resecables", de resección límite "Borderlines" y "localmente avanzados". Se presenta el primer caso registrado en Paraguay de APD con infiltración de la Vena Mesentérica Superior (VMS) tratado con duodenopancreatectomía cefálica (DPC) asociada a resección vascular mayor.


Pancreatic ductal adenocarcinoma (PDA) is the fourth leading cause of cancer death and is projected to rank second by 2030. The prognosis is bleak, with survival being less than 9% in 5 years. For a long time, surgical resection was considered the only curative treatment, however, only 15 to 20% of patients can benefit from it. The most widely used pre-therapeutic classification is that of the National Comprehensive Cancer Network (NCCN), based on the relationship of the tumor with vascular structures, classifying them into "resectable", "borderline" and "locally advanced" tumors. We present the first registered case in Paraguay of PDA with infiltration of the Superior Mesenteric Vein (SMV) treated with cephalic duodenopancreatectomy (CPD) associated with major vascular resection.

ABSTRACT

Abstract Introduction Patient reported outcomes establish the patient's own perception about his/her health and enable the development of policies designed to improve health/disease processes. These are particularly helpful in the case of diseases with a significant impact on the patient's quality of life. Objective To compare the quality of life scores assessed using the EQ-5D-5L questionnaire in patients undergoing cephalic duodenopancreatectomy (Whipple procedure) and laparoscopic cholecystectomies in the same hospital. Methodology Retrospective cohort trial between July 2018 and February 2020. Patients programmed for cephalic duodenopancreatectomy were included, regardless of the type of pathology, and over 18 years old. Patients with carcinomatosis or vascular infiltration were excluded. The EQ-5D-5L was administered following Whipple surgery and compared against a control group (laparoscopic cholecystectomy). The demographic characteristics, the diagnosis, hospital stay and 60-day mortality were assessed. Results A total of 68 patients were included. The most frequent diagnosis was pancreatic cancer (30 %) in the Whipple group and lithiasis (100 %) in the control group. In the five dimensions assessed, there were no differences in terms of mobility (OR: 0.41, 95 % CI [0.30-0.57], p = 0.103) and in terms of personal care (OR: 0.42, 95 % CI [0.32-0.58], p = 0.254). There was a difference in daily life activities (OR: 0.38, 95 % CI [0.27-0.54], p = 0.017), pain/malaise (OR: 2.33, 95 % CI [0.99-5.48]), p = 0.013 and anxiety/depression (OR: 0.39, 95 % CI [0.28-0.55], p = 0.019). The overall health perception was 80 points for Whipple (IQR 60-90) vs. 100 points for the control group (IQR 90-100). Conclusions Patients undergoing a Whipple procedure experience a health perception slightly lower than patients undergoing laparoscopic cholecystectomy. This difference may be associated with increased pain, anxiety/depression and a reduction in their activities of daily life. The administration of the EQ-5D-5L questionnaire to measure quality of life is a friendly tool that used be used routinely to plan activities aimed at improving medical care.


Resumen Introducción Los desenlaces informados por el paciente permiten establecer cuál es la percepción que tiene de su salud y crear políticas que mejoren procesos en salud/enfermedad. Son particularmente útiles en enfermedad que afectan la calidad de vida de forma importante. Objetivo Comparar las puntuaciones de calidad de vida evaluadas mediante el cuestionario EQ-5D-5L en pacientes sometidos a duodenopancreatectomía cefálica (procedimiento de Whipple) y colecistectomías laparoscópicas en el mismo centro hospitalario. Metodología Estudio de cohorte retrospectivo entre julio de 2018 y febrero de 2020. Se incluyeron pacientes programados para duodenopancreatectomía cefálica independientemente del tipo de patología y mayor de 18 años de edad; se excluyeron pacientes con carcinomatosis o infiltración vascular. Se aplicó el cuestionario EQ-5D-5L después de cirugía Whipple y se comparó con un grupo control (colecistectomía laparoscópica). Se evaluaron características demográficas, diagnóstico, estancia hospitalaria y mortalidad a 60 días. Resultados Se incluyeron 68 pacientes. El diagnóstico más frecuente fue cáncer de páncreas (30 %) en el grupo Whipple y litiasis (100 %) en el grupo control. En las 5 dimensiones evaluadas no hubo diferencias en movilidad (OR: 0,41, IC 95 % [0,30-0,57], p = 0,103) y en cuidado personal (OR: 0,42, IC 95 % [0,32-0,58], p = 0,254). Se encontró diferencia en actividades cotidianas (OR: 0,38, IC 95 % [0,270,54], p = 0,017), dolor/malestar (OR: 2,33, IC 95 % [0,99-5,48]), p = 0,013 y angustia/depresión (OR: 0,39, IC 95 % [0,28-0,55], p = 0,019). La percepción general de salud fue 80 puntos para Whipple (RIQ60-90) vs. 100 puntos para el grupo control (RIC 90-100). Conclusiones Los pacientes sometidos a Whipple presentan una percepción de salud ligeramente menor que los pacientes de colecistectomía laparoscópica. Esta diferencia puede estar relacionada con el aumento en dolor, angustia/depresión y disminución en actividades cotidianas. La aplicación del cuestionario EQ-5D-5L para medición de calidad de vida es una herramienta fácil de aplicar que debería realizarse rutinariamente para planear intervenciones dirigidas a mejorar la atención médica.

ABSTRACT

SUMMARY OBJECTIVE: To analyze abdominal drain on the first postoperative day and evaluate its predictive nature for the diagnosis of Pancreatic Fistula exclusion, seeking to establish a cutoff point from which lower values demonstrate safety in excluding the possibility of this complication. METHODS: From August 2017 to June 2020, data from 48 patients undergoing pancreatic resection were collected and analyzed from a prospective cohort. The patients were divided into two groups, one group consisting of patients who did not develop PF (Group A), and the other composed of patients who developed PF (Group B). The receiver operation characteristic curve was constructed, and cutoff points were evaluated by calculating sensitivity and specificity. RESULTS: Group A brought 30 patients together (62.5%) and Group B brought 18 patients together (37.5%). The 444 U/L value was the most satisfactory cutoff point for the receiver operation characteristic curve (CI 0.690-0.941), with a sensitivity of 94.4% and a specificity of 60%, thus being able to select 18 of 30 patients who did not succumb to PF. CONCLUSIONS: Abdominal drain on the first postoperative day can be used as a predictive factor in the diagnosis of PF exclusion (CI 0.690-0.941), with the value of 444 U/L being the best performance cutoff point.

ABSTRACT

ABSTRACT Background: The delay in gastric emptying is the second most frequent complication after duodenopancreatectomy with pyloric preservation, that increases hospitalization time and hospital costs. Aim: To identify factors that contribute to the appearance the delay in this surgical procedure. Method: Ninety-five patients were submitted to duodenopancreatectomy with pyloric preservation. After retrospective analysis of the medical records, it was observed that 60 had prolonged hospitalization due to complications. Thus, univariate and multivariate logistic regression were used to analyze predictors of delayed gastric emptying. Results: Delay was present in 65% (n=39) and pancreatic fistula in 38.3% (n=23). Univariate analysis revealed that the presence of pancreatic complications (pancreatic fistula, p=0.01), other intracavitary complications with the appearance of abdominal collections (p=0.03) and hypoalbuminemia (p=0.06) were responsible, also confirmed by the multivariate analysis. In those who presented delay without a determined cause, it was observed that high levels of total bilirubin (p=0.01) and direct bilirubin (p=0.01) could be related to it. Conclusion: The delay in gastric emptying in patients undergoing duodenopancreatectomy with pyloric preservation is due to intracavitary complications.


RESUMO Racional: O retardo do esvaziamento gástrico é a segunda complicação mais frequente após a realização da duodenopancreatectomia com preservação pilórica, aumentando o tempo de internação e custos hospitalares. Objetivo: Identificar fatores que contribuem para o aparecimento desse retardo nesse procedimento cirúrgico. Método: Noventa e cinco doentes foram submetidos à duodenopancreatectomia com preservação pilórica. Após análise retrospectiva dos prontuários observou-se que 60 apresentaram internação prolongada por complicações. Assim, utilizou-se a regressão logística uni e multivariada para análise de fatores preditores do retardo. Resultados: O retardo esteve presente em 65% (n=39) e a fístula pancreática em 38,3% (n=23). A análise univariada revelou que a presença de complicações pancreáticas (fístula pancreática, p=0,01), outras complicações intracavitárias com aparecimento de coleções abdominais (p=0,03) e hipoalbuminemia (p=0,06) foram os responsáveis, resultados estes também confirmados pela análise mutilvariada. Naqueles que apresentaram retardo sem causa determinada, observou-se que níveis elevados de bilirrubina total (p=0,01) e bilirrubina direta (p=0,01) poderiam estar relacionados a ele. Conclusão: O retardo do esvaziamento gástrico nos pacientes submetidos à duodenopancreatectomia com preservação pilórica é decorrente de complicações intracavitárias.

ABSTRACT

Resumen Introducción: El tumor sólido pseudopapilar del páncreas es una rara entidad que representa menos del 1% de las neoplasias pancreáticas. Suele presentarse en mujeres jóvenes y solo da síntomas de carácter compresivo una vez que alcanza un gran tamaño. Dado su comportamiento biológico incierto el tratamiento es la cirugía. Caso Clínico: Presentamos el caso de una mujer de 23 años con historia de 1 año de evolución de dolor epigástrico y baja de peso. El estudio imagenológico demostró una masa heterogénea sólida-quística dependiente de la cabeza del páncreas de aspecto neoplásico. Se realizó una biopsia incisional laparoscópica cuyo resultado fue de un tumor maligno indiferenciado, por lo que se optó por la resección quirúrgica. Se realizó una pancreatoduodenectomía abierta sin incidentes con un postoperatorio favorable. Los análisis histopatológicos e inmunohistoquímico fueron compatibles con un tumor sólido pseudopapilar de páncreas.


Introduction: The pseudopapillary solid tumor of the pancreas is a rare entity that represents less than 1% of pancreatic neoplasms. It usually occurs in young women and only gives symptoms of a compressive nature once it has reached a large size. Given its uncertain biological behavior, the treatment is surgery. Case Report: We present the case of a 23-year-old woman with a 1-year history of epigastric pain evolution and weight loss. The imaging study demonstrated a solid-cystic heterogeneous mass dependent on the head of the pancreas of neoplasic appearance. A laparoscopic incisional biopsy was performed, the result of which was an undifferentiated malignant tumor, which was why the surgical resection was chosen. An open pancreatoduodenectomy was performed without incident with a favorable post operative. Histopathological and immunohistochemical analyzes were compatible with a solid pseudopapillary tumor of the pancreas.

ABSTRACT

Antecedentes: La duodenopancreatectomía cefálica (D.P.C.) es el procedimiento quirúrgico aceptado para el tratamiento de los tumores malignos y benignos del confluente bilio-duodenopancreático. Lugar de aplicación: Hospital Nacional de Clínicas y Clínica privada. Diseño: Estudio protocolizado y prospectivo. Material y método: Entre diciembre 2000 y diciembre 2014 se operaron 96 DPC. Las indicaciones de la cirugía fueron: 39 cánceres de la cabeza de páncreas, 19 cánceres de papila, 9 cáncer de duodeno, 10 de colédoco distal, 5 tumores quísticos del páncreas, 4 pancreatitis crónica, 3 tumores funcionantes de páncreas, 3 tumores no funcionantes, finalmente 3 tumores de otra etiología. Resultados: Con respecto a la mortalidad dentro de los 30 días, fallecieron 5 pacientes (4, 80 %). Posteriormente, fallecieron dentro de los 90 días 5 pacientes más (9,3 %). En las complicaciones quirúrgicas, nosotros encontramos: la fistula pancreática hubo en 32 pacientes. Con respecto al Vaciamiento gástrico estuvo presente en 19 enfermos y finalmente en 5 pacientes tuvieron una hemorragia intra peritoneal que fueron re intervenidos y uno de los cuales falleció. Por otro lado, hubo 11 colecciones abdominales, donde se re operaron 4 pacientes y a los 7 restantes se les colocó un drenaje en dicha colección. Se re intervinieron 4 pacientes con evisceración, CONCLUSIONES: Los resultados de nuestro trabajo, apoyan el concepto que cirujanos con bajo volumen de D.P.C. anuales, pero con una estricta formación en Instituciones con infraestructura adecuada y un equipo multidisciplinario, pueden también obtener buenos resultados en las lesiones malignas y benignas del confluente bilio-duodeno-pancreático


Background: Cephalic duodenopancreatectomy (CDP) (pancreaticoduodenectomy of the head of the pancreas) is the surgical option accepted as the procedure of choice for the management of both malignant and benignant tumours of the duodenal-pancreatic biliary confluence. Setting: National Clinical Hospital and private practice. Desing: Protocoled and prospective study. Methods: Between December 2000 through December 2014, 96 CDP have been operated upon: 39 cancers of the head of the pancreas, 19 cancers of the papilla, 9 cancers of the duodenum, 10 of the distal common bile ducts, 5 cystic tumours of the pancreas, 4 chronic pancreatitis, 3 functioning pancreas, 3 non-functioning tumours, and finally 3 tumours of different ethiologies: 1 GIST of duodenum, 1 metastasis from a renal cancer, and 1 colon cancer of the hepatic flexure who invaded the duodenum. Results: Pancreatic fistulas were observed in 32 patients. With reference to gastric emptying it was present in 19 patients, and finally in 5 patients an intra peritoneal haemorrhage was present which were re- intervened, and one of them died. On the other hand, 11 abdominal collections were present, of whom 4 patients were re-operated, and to the remaining 7 ,a drainage was placed in the collection. Four patients were re-operated with evisceration. Conclusions: The results of our study support the concept that surgeons with low volume of annual CDP, but with strict training in institutions with adequate infrastructure and a multidisciplinary team, can obtain also good results.

ABSTRACT

Abstract Purpose: This study aimed to investigate factors associated with postoperative Acute Kidney Injury (AKI) focusing on intraoperative hypotension and blood loss volume. Methods: This was a retrospective cohort study of patients undergoing pancreas surgery between January 2013 and December 2018. The primary outcome was AKI within 7 days after surgery and the secondary outcome was the length of hospital stay. Multivariate analysis was used to determine explanatory factors associated with AKI; the interaction between the integrated value of hypotension and blood loss volume was evaluated. The differences in length of hospital stay were compared using the Mann-WhitneyU-test. Results: Of 274 patients, 22 patients had experienced AKI. The cube root of the area under intraoperative mean arterial pressure of < 65 mmHg (Odds Ratio = 1.21; 95% Confidence Interval 1.01-1.45; p = 0.038) and blood loss volume of > 500 mL (Odds Ratio = 3.81; 95% Confidence Interval 1.51-9.58; p = 0.005) were independently associated with acute kidney injury. The interaction between mean arterial hypotension and the blood loss volume in relation to acute kidney injury indicated that the model was significant (p < 0.0001) with an interaction effect (p = 0.0003). AKI was not significantly related with the length of hospital stay (19 vs. 28 days, p = 0.09). Conclusion: The area under intraoperative hypotension and blood loss volume of > 500 mL was associated with postoperative AKI. However, if the mean arterial pressure is maintained even in patients with large blood loss volume, the risk of developing postoperative AKI is comparable with that in patients with small blood loss volume.


Resumo Justificativa: O presente estudo teve como objetivo examinar os fatores associados à Lesão Renal Aguda (LRA) no pós-operatório, centrando-se na hipotensão e perda de sangue intraoperatórias. Método: Estudo de coorte retrospectivo de pacientes submetidos a cirurgia de pâncreas entre Janeiro de 2013 e Dezembro de 2018. O desfecho primário foi ocorrência de LRA em até 7 dias após a cirurgia e o secundário, o tempo de hospitalização. A análise multivariada foi usada para determinar os fatores explicativos associados à LRA; a interação entre o valor integrado da hipotensão e volume de perda de sangue foi avaliada. As diferenças no tempo de hospitalização foram comparadas pelo teste U de Mann-Whitney. Resultados: Dos 274 pacientes, 22 pacientes apresentaram LRA. A raiz cúbica da área sob a pressão arterial média intraoperatória < 65 mmHg (Odds Ratio = 1,21; Intervalo de Confiança de 95% 1,01-1,45; p = 0,038) e volume de perda sanguínea > 500 mL (Odds Ratio = 3,81; Intervalo de Confiança de 95% 1,51-9,58; p = 0,005) estavam independentemente associados à lesão renal aguda. A interação entre hipotensão arterial média e volume de perda sanguínea em relação à lesão renal aguda apontou o modelo como significante (p < 0,0001) com efeito de interação (p = 0,0003). A LRA não apresentou relação significante com o tempo de hospitalização (19 vs. 28 dias, p = 0,09). Conclusões: A área sob hipotensão arterial e o volume de perda sanguínea > 500 mL no intraoperatório apresentaram associação com LRA no pós-operatório. Entretanto, se a pressão arterial média se mantém, mesmo em pacientes com grande volume de perda sanguínea, o risco de desenvolver LRA no pós-operatório é comparável ao risco dos pacientes com pequeno volume de perda sanguínea.

ABSTRACT

RESUMEN Antecedentes: la pancreatitis aguda posduodenopancreatectomía cefálica inmediata es una complica ción cuya frecuencia puede llegar al 55% y condiciona la aparición de fístula pancreática. Objetivo: describir el manejo de 3 pacientes que presentaron pancreatitis aguda posduodenopancrea tectomía con complicaciones locales y realizar una revisión de la literatura. Material y métodos: se revisó una base de datos prospectiva de resecciones pancreáticas. Se identifi caron los pacientes con diagnóstico de pancreatitis aguda con lesiones locales posterior a la realización de duodenopancreatectomía. Se definió fístula pancreática de acuerdo con la clasificación del ISGPF y pancreatitis como la elevación de la amilasa o lipasa tres veces por encima del máximo valor sérico normal en asociación con dolor abdominal o confirmación radiológica. Resultados: entre 2008 y 2019 los autores realizaron 260 duodenopancreatectomías. Tres pacientes presentaron pancreatitis posoperatoria con complicaciones locales. Conclusiones: la pancreatitis aguda posoperatoria es una complicación de una frecuencia elevada. La mayoría de ellas se resuelven en forma espontánea. Pocos pacientes presentan complicaciones locales que pueden requerir tratamiento percutáneo o quirúrgico, predisponiendo al desarrollo de fístulas a veces de difícil manejo. No hay forma de prevenir la aparición de la fístula pancreática. El tratamiento de las complicaciones locales se realizará de acuerdo con su aparición y repercusión, pudiendo requerir desde la colocación de un drenaje percutáneo hasta la pancreatectomía total.


ABSTRACT Background: The incidence of acute pancreatitis immediately after cephalic pancreaticoduodenec tomy is up to 55% and is associated with the development of pancreatic fistula. Objective: The aim of this study is to report three cases of acute pancreatitis after pancreaticoduode nectomy with local complications with a review of the literature. Material and methods: The information about pancreatic resections was retrieved from a prospective database. Patients with diagnosis acute pancreatitis with local lesions immediately after pancreatico duodenectomy were identified. Pancreatic fistula was defined according to the International Study Group on Pancreatic Fistula (ISGPF) Definition and pancreatitis was defined as serum amylase or lipase >3x upper limit of normal associated with abdominal pain or imaging criteria. Results: A total of 260 pancreaticoduodenectomies were performed between 2008 and 2019. Three patients developed postoperative acute pancreatitis with local complications. Conclusions: Postoperative acute pancreatitis is a common complication that solves spontaneously in most cases. Few patients present local complications that may require percutaneous or surgical treatment, which may predispose to the development of fistulas that are sometimes difficult to mana ge. There is no way to prevent pancreatic fistulas. Local complications will be treated according to their occurrence and impact, and may require a variety of procedures, ranging from percutaneous drainage to total pancreatectomy.

Lugar de aplicación: hospital nacional de clínicas y clínica privada. Diseño: estudio protocolizado y prospectivo. Material y método: entre diciembre 2000 y diciembre 2014 se operaron 96 dpc. De ellos, 54 del sexo masculino y 42 del femenino, cuyas edades oscilaron entre 27 y 79 años de edad (media de 59 años). El promedio del período de tiempo entre el inicio de los síntomas y la primera consulta fue de 81 días (rango 10 a 129 días). A todos los pacientes se les llevo a cabo ecografía y tac de abdomen. Resultados: con respecto a la mortalidad dentro de los 30 días, fallecieron 5 pacientes (4, 80 %). Posteriormente, fallecieron dentro de los 90 días 5 pacientes más (9,3 %). Con respecto a la morbilidad, las dividimos en clínicas que fueron 17 pacientes (16,32 %) y 50 fueron quirúrgicas (48 %). Dentro de ellas la fistula pancreática estuvo en 32 pacientes (30,72 %). Con respecto al vaciamiento gástrico estuvo presente en 19 (18,24 %) y finalmente 5 (4,80 %) tuvieron una hemorragia intra peritoneal. Ocho pacientes tuvieron una fistula biliar (7,62 %). Conclusiones: los resultados de nuestro trabajo, apoyan el concepto que cirujanos con bajo volumen de d.P.C. Anuales, pero con una estricta formación en instituciones con infraestructura adecuada y un equipo multidisciplinario, pueden también obtener buenos resultados en las lesiones malignas y benignas del confluente bilio-duodeno-pancreático


Background: Cephalic pancreatoduodenectomy (CPD) is the surgical procedure of choice accepted for the management of both the malignant and the benign tumors of the bilio- duodeno pancreatic confluence. Setting: Clinico- National Hospital and private practice. Desing: protocoled and prospective study. Methods: between december 2000 and december 2014, 96 cpd have been operated. Of these, 54 were men and 42 were women, with ages ranged between 27 to 79 years (average 59 years). The time between the onset of symptoms and the first consultation period. Averaged 81 days (range 10-129 days). All the patients were submitted to ultrasound and ct of the abdomen. Results: with reference to mortality within 30 days, 5 patients (4, 80%) died. Subsequently, 5 more patients died within 90 days (9.3%). With reference to morbidity, we divided them in two, clinicals that were 17 patients (16.32%) And 50 were surgical (48%). Within pancreatic fistula included 32 patients (30, 72%). With reference to the gastric emptying, it was present in 19 (18.24%) And finally 5 (4.80%) Had intra peritoneal bleeding. In addition, 8 patients had a biliary fistula (7.62%). Conclusions: the results of our study support the concept that surgeons with low volume of cpd annually, but with strict training in institutions with adequate infraestructure and a multidisciplinary team, can also obtain good results in the malignant and benign lesions of the biliary-duodeno-pancreatic confluence.

ABSTRACT

PURPOSE: The International Study Group on Pancreatic Fistula's definition of postoperative pancreatic fistula (POPF) has recently been updated. This study aimed to identify risk factors for POPF in patients having pancreaticoduodenectomy (PD) and to generate a nomogram to predict POPF.METHODS: Data on 298 patients who underwent PD from March 2012 to October 2017 was retrospectively reviewed and POPF statuses were redefined. A nomogram was constructed using data from 220 patients and validated using the remaining 78 patients. Independent risk factors for POPF were identified using univariate and multivariate analyses. A predictive nomogram was established based on the independent risk factors and was compared with existing models.RESULTS: Texture of the pancreas, size of the main pancreatic duct, portal vein invasion, and definitive pathology were the identified risk factors. The nomogram had a C-index of 0.793 and was internally validated. The nomogram performed better (C-index of 0.816) than the other most cited models (C-indexes of 0.728 and 0.735) in the validation cohort. In addition, the nomogram can assign patients into low- (less than 10%), intermediate- (10% to 30%), and high-risk (equal or higher than 30%) groups to facilitate personalized management.CONCLUSION: The nomogram accurately predicted POPF in patients having PD.

ABSTRACT

PURPOSE: Pancreaticoduodenectomy (PD) is recently performed in older cancer patients. The complication rate of PD is high. The present study was to compare the postoperative short- and long-term outcomes of PD in between older patients and younger patients.METHODS: Between 2000 and 2014, patients who underwent PD due to periampullary cancers were enrolled. Patients aged 75 years or over were included in the older group.RESULTS: Total 1,249 patients were enrolled in this study and 168 patients (13.5%) were included in the older group. Postoperative complication rates, duration of postoperative hospital stay, and 30-day mortality were comparable between the 2 groups, although the admission rate of intensive care unit postoperatively was higher in the older adult group (20.8% vs. 10.5%, P < 0.001). In terms of long-term outcomes, 5-year overall survival rate was lower in the older group (23.4% vs. 41.8%, P < 0.001), and 5-year cumulative recurrence rate was higher in the older group without statistical significance (63.9% vs. 57.9%, P = 0.095). However, there were no statistical differences of cumulative recurrence in pancreatic cancer patients (81.5% vs. 82.5%, P = 0.805).CONCLUSION: PD for periampullary cancer is a safe and feasible treatment in the older patients.

ABSTRACT

ABSTRACT Objective: the first robotic pancreatic resection in Brazil was performed by our team in 2008. Since March 2018, a new policy prompted us to systematically employ the robot in all minimally invasive pancreatic surgery. The aim of this paper is to review our experience with robotic pancreatic resection. Methods: all patients who underwent robotic pancreatic resection from March 2018 through December 2019 were identified. Descriptive data were collected. Preoperative variables included age, sex, and indication for surgery. Intraoperative variables included operative time, bleeding, blood transfusion. Results: 105 patients underwent robotic pancreatectomy. Median age was 60.5 years old. Fifty-five patients were female. 51 patients underwent robotic pancreatoduodenectomies, 34 distal pancreatectomy. Morbidity was 23.8%, mainly related to postoperative pancreatic fistula and one death occurred (mortality of 0.9%). Three patients (2.8%) were converted to open surgery. Four patients had delayed gastric emptying and two presented bleeding. Twenty-four patients had pancreatic fistula that was treated conservatively with late removal of the pancreatic drain. No patient required percutaneous drainage, reintervention or hospital readmission. Conclusions: the robotic platform is useful for the reconstruction of the alimentary tract after pancreatoduodenectomy or after central pancreatectomy. It may increase the preservation of the spleen during distal pancreatectomies. Pancreas sparing techniques, such as enucleation, resection of uncinate process and central pancreatectomy, should be used to avoid exocrine and/or endocrine insufficiency. Robotic resection of the pancreas is safe and feasible for selected patients. It should be performed in specialized centers by surgeons with experience in both open and minimally invasive pancreatic surgery.


RESUMO Objetivo: a primeira ressecção pancreática robótica no Brasil foi realizada por nossa equipe em 2008. Desde março de 2018, uma nova política nos levou a empregar sistematicamente o robô em todas cirurgias pancreáticas minimamente invasivas. O objetivo deste artigo é revisar nossa experiência com a ressecção pancreática robótica. Métodos: todos os pacientes submetidos a ressecção pancreática robótica de 2018 a 2019 foram incluídos. Variáveis pré- e intraoperatórias como idade, sexo, indicação, tempo cirúrgico, sangramento, diagnóstico, tamanho do tumor foram analisados. Resultados: 105 pacientes foram submetidos a pancreatectomia robótica. A idade mediana dos pacientes foi de 60,5 anos. 55 pacientes eram do sexo feminino. 51 pacientes foram submetidos a pancreatoduodenectomia, 34 pancreatectomia distal. A morbidade foi de 23,8% e ocorreu um óbito (mortalidade de 0,9%). Três pacientes (2,8%) tiveram a operação convertida para aberta. Quatro pacientes apresentaram retardo no esvaziamento gástrico e dois apresentaram sangramento. Vinte e quatro pacientes apresentaram fístula pancreática tratada de forma conservadora com remoção tardia do dreno pancreático. Nenhum paciente necessitou de drenagem percutânea, reintervenção ou readmissão hospitalar. Conclusões: a plataforma robótica é útil para a reconstrução do trato alimentar após pancreatoduodenectomia ou após pancreatectomia central. Pode aumentar a preservação do baço durante pancreatectomias distais. Técnicas poupadoras de pâncreas, como enucleação, ressecção de processo uncinado e pancreatectomia central, devem ser usadas para evitar insuficiência exócrina e/ou endócrina. A ressecção robótica do pâncreas é segura e viável para pacientes selecionados. Deve ser realizada em centros especializados por cirurgiões com experiência em cirurgia pancreática aberta e minimamente invasiva.

ABSTRACT

Resumen Introducción: La duodeno pancreatectomía cefálica es una operación compleja cuyos resultados a corto plazo son multifactoriales. Objetivo: Evaluar el impacto de la curva de aprendizaje en los resultados a corto plazo de la duodenopancreatectomía cefálica en un hospital de nivel II. Materiales y Método: Se analizaron los datos obtenidos a partir de una base de datos mantenida prospectivamente desde 2005. Se definieron dos periodos de tiempo: de 2005 a 2011 y de 2012 a 2017. Se compararon la morbilidad, mortalidad y estancia postoperatoria de ambos períodos. Resultados: Durante el período de tiempo estudiado se hicieron 126 duodenopancreatectomías cefálicas, 61 durante la primera etapa y 65 durante la segunda. La tasa de transfusión intraoperatoria se redujo de 33% a 15% (p = 0,011). La tasa de transfusión postoperatoria se redujo de 39 a 23% (p = 0,021). No hubo diferencias significativas con respecto a la incidencia global de complicaciones postoperatorias (59% y 52,3%). La incidencia de abscesos intraabdominales fue significativamente menor en el segundo período (18% y 4,6%, respectivamente; p = 0,038). La tasa de reintervenciones se redujo significativamente, de 22% a 9% (p = 0,049). También se redujo significativamente la tasa de mortalidad, de 6,56% a 0% (p = 0,032). La estancia media postoperatoria disminuyó significativamente en el segundo período, pasando de 19,6 a 15,8 días (p = 0,001), con una mayor proporción de pacientes dados de alta en los 8 primeros días de postoperatorio (11,5% y 38,5%, respectivamente; p = 0,001). Conclusión: La curva de aprendizaje es un factor que permite mejorar los resultados de la duodenopancreatectomía cefálica, en un hospital de nivel II, hasta alcanzar valores similares a los de un hospital de nivel III.


Introduction: The duodenum pancreatectomy cephalic is a complex operation whose short-term results are multifactorial. Aim: To assess the impact of the learning curve on the short-term outcomes of cephalic duodenopancreatectomy at a level II hospital. Materials Method: We analyze the data obtained from a database maintained prospectively since 2005. Two time periods were defined: from 2005 to 2011 and from 2012 to 2017. The morbidity, mortality and postoperative stay of both periods were compared. Results: 126 cephalic duodenopancreatectomies were performed, 61 during the first period and 65 during the second. The intraoperative transfusion rate was reduced from 33% to 15% (p = 0.011). The postoperative transfusion rate was reduced from 39 to 23% (p = 0.021). There were no significant differences with respect to the overall incidence of postoperative complications (59% and 52.3%, respectively). However, the incidence of intra-abdominal abscesses was significantly lower in the second period (18% and 4.6%, respectively, p = 0.038). The rate of reoperations was significantly reduced, from 22% to 9% (p = 0.049). The mortality rate was also significantly reduced, from 6.56% to 0% (p = 0.032). The mean postoperative stay decreased significantly in the second period, from 19.6 to 15.8 days (p = 0.001), with a higher proportion of patients discharged in the first 8 postoperative days (11.5% and 38.5%, respectively, p = 0.001). Conclusion: The learning curve is a factor allows improving the results of cephalic pancreaticoduodenectomy, in a level II hospital, until reaching values similar to those of a level III hospital.

ABSTRACT

Abstract Background: The administration of perioperative fluids is a controversial issue that can be associated with the development of postoperative pancreatic fistula (POPF) after Whipple procedure. Objective: To evaluate whether intraoperative fluid management along with Enhanced Recovery after Surgery (ERAS) protocols affect outcomes following major pancreatic resection. Methods: A retrospective cohort study was conducted from January 2012 to January 2017, collecting all patients scheduled for duodenopancreatectomy (DP). Patients were divided into 2 groups according to the use of ERAS protocols and the use of a fluid therapy algorithm. Results: A total of 67 patients were analyzed, 49.3% of which were females. The most frequent diagnoses were Pancreatic Cancer n:48 (71.6%), followed by intraductal papillary mucinous neoplasm n:6 (9%). The majority of patients were in the ERAS group n:46 (68.7%); 80.4% and 95.7% of them did not develop pancreatic fistula or delayed gastric emptying (DGE) respectively, and the incidence for both was 11.94%. Fluid therapy was below 5000 mL (P=0.001) with blood loss less 300 mL (P = 0.001) in the ERAS group. The length of stay was shorter in the ERAS group (7 days, interquartilel range 5-12, P < 0.001). No differences in 30 days mortality were found. Conclusion: The implementation of ERAS protocols in DP did show a decrease in intraoperative blood loss, intravenous fluids therapy, need for transfusion, DGE, or total hospital stay. However, intraoperative fluid restriction in DP did not show a reduction in the development of POPF.


Resumen Introducción: La administración de fluidos durante el perioperatorio es un tema controvertido que puede asociarse a complicaciones como la fístula pancreática después de realizar el procedimiento de Whipple. Objetivo: Evaluar si los protocolos de manejo de líquidos dentro de las recomendaciones de recuperación acelerada después de cirugía (ERAS) afectan los desenlaces después de intervención pancreática mayor. Materiales y métodos: Se realizó un estudio de cohorte retrospectivo entre enero de 2012 y enero de 2017. Se recopilaron todos los pacientes a quienes se les practicó duodenopancreatectomía. Se dividieron en dos grupos según el uso de protocolos ERAS y el uso de algoritmos para terapia hídrica. Resultados: Se analizaron 67 pacientes, el 49,3% correspondió al sexo femenino. Los diagnósticos más frecuentes fueron cáncer de páncreas n: 48 (71,6%), seguido de neoplasia mucinosa papilar intraductal n: 6 (9%). La mayoría de los pacientes se encontraban en el Grupo ERAS n:46(68,7%).En dicho grupo, el 80,4% y el 95,7% no desarrollaron fístula pancreática o retraso del vaciamiento gástrico y la incidencia fue del 11,94%, respectivamente. La terapia hídrica estuvo por debajo de 5000 ml (p = 0,001) con una pérdida sanguínea inferior a 300 ml (p=0,001) en el grupo ERAS. La estancia hospitalaria fue más corta en el grupo ERAS (7 días, rango intercuartil [RIC] 5-12, p =<0,001). No hubo diferencias en la mortalidad a 30 días. Conclusión: La implementación de protocolos ERAS en la duodenopancreatectomía mostró una menor pérdida sanguínea, menor terapia hídrica, menor necesidad de transfusión, menor retraso del vaciamiento gástrico y menor estancia hospitalaria. Sin embargo, la terapia hídrica restrictiva no redujo el desarrollo de fístula pancreática postoperatoria.

ABSTRACT

ABSTRACT BACKGROUND: Pancreaticoduodenectomy (PD) with the resection of venous structures adjacent to the pancreatic head, even in cases of extensive invasion, has been practiced in recent years, but its perioperative morbidity and mortality are not completely determined. OBJECTIVE: To describe the perioperative outcomes of PD with venous resections performed at a tertiary university hospital. METHODS: A retrospective study was conducted, classified as a historical cohort, enrolling 39 individuals which underwent PD with venous resection from 2000 through 2016. Preoperative demographic, clinical and anthropometric variables were assessed and the main outcomes studied were 30-day morbidity and mortality. RESULTS: The median age was 62.5 years (IQ 54-68); 55% were male. The main etiology identified was ductal adenocarcinoma of the pancreas (82.1%). In 51.3% of cases, the portal vein was resected; in 35.9%, the superior mesenteric vein was resected and in the other 12.8%, the splenomesenteric junction. Regarding the complications, 48.7% of the patients presented some type of morbidity in 30 days. None of the variables analyzed was associated with higher morbidity. Perioperative mortality was 15.4% (six patients). The group of individuals who died within 30 days presented significantly higher values for both ASA (P=0.003) and ECOG (P=0.001) scores. CONCLUSION: PD with venous resection for advanced pancreatic neoplasms is a feasible procedure, but associated with high rates of morbidity and mortality; higher ASA e ECOG scores were significantly associated with a higher 30-day mortality.


RESUMO CONTEXTO: A duodenopancreatectomia (DP) com ressecção de estruturas venosas adjacentes à cabeça do pâncreas, mesmo em casos de invasão extensa, tem sido praticada nos últimos anos, mas sua morbidade e mortalidade perioperatórias não são completamente determinadas. OBJETIVO: Descrever os resultados perioperatórios de DP com ressecções venosas realizadas em um hospital terciário universitário. MÉTODOS: Foi realizado estudo retrospectivo, classificado como coorte histórica, envolvendo 39 indivíduos submetidos à DP com ressecção venosa entre 2000 e 2016. Foram estudadas variáveis demográficas, clínicas e antropométricas pré-operatórias e os desfechos principais foram a morbidade e mortalidade em 30 dias. RESULTADOS: A mediana de idade foi 62,5 anos (IQ 54-68), sendo 55% dos indivíduos do sexo masculino. A principal etiologia identificada foi o adenocarcinoma ductal de pâncreas (82,1%). Em 51,3% dos casos, a veia porta foi submetida à ressecção; em 35,9%, a veia mesentérica superior foi ressecada e nos outros 12,8%, a junção esplenomesentérica. Em relação às complicações, 48,7% dos pacientes apresentaram algum tipo de morbidade em 30 dias. Nenhuma das variáveis analisadas associou-se à maior morbidade. A mortalidade perioperatória foi 15,4% (seis pacientes). O grupo de indivíduos que cursou com mortalidade em 30 dias apresentou escores significativamente mais altos de ASA (P=0,003) e ECOG (P=0,001). CONCLUSÃO: A DP com ressecção venosa para neoplasias avançadas do pâncreas é um procedimento factível, porém que se acompanha de altos índices de morbidade e mortalidade; escores de ASA e ECOG altos são fatores significativamente associados à maior mortalidade.

ABSTRACT

Antecedentes: la duodenopancreatectomía (DPC) continúa siendo el tratamiento de elección para los tumores periampulares. Con una mortalidad de alrededor del 5% y una morbilidad que puede llegar a alrededor del 50%, la fístula pancreática es todavía la complicación preponderante. Diversos autores sostienen que la anastomosis del páncreas con el estómago tiene menor índice de fístula que cuando se realiza con el yeyuno. Objetivo: comparar la incidencia de fístula pancreática en las pancreatogastrostomías (PG) versus pancreatoyeyunostomías (PY). Evaluar algunos factores de riesgo de fístula. Material y métodos: se evaluaron 91 DPC, 43 de ellas con reconstrucción con PG y 48 con PY. Se evaluaron datos demográficos, quirúrgicos, y se comparó la incidencia de fístula entre ambos. Resultados: la incidencia global de fístula fue de 13 pacientes (14,3%), 5 de las cuales fueron de relevancia clínica. En la comparación de ambos grupos hubo diferencias en cuanto a edad y número de pacientes con Wirsung < 3 mm, el resto de los parámetros fue similar. No hubo diferencias entre ambos grupos con respecto a la cantidad de fístulas (p: 0,478). Respecto de la evaluación de factores predisponentes para fístula, tan solo un diámetro del Wirsung < 3 mm fue significativo. Conclusión: en nuestra serie y al igual que en otras no hubo diferencias en cuanto a fístulas pancreáticas entre PG y PY, lo que nos permite inferir que la adopción y confección sistemática de una ellas obtendrá los mejores resultados.


Background: Pancreaticoduodenectomy is still the treatment of choice in patients with periampullary tumors. Pancreatic fistula is the most common complication with a mortality rate of 5% and 50% of morbidity. Some authors state that the anastomosis of the pancreas with the stomach would decrease the incidence of pancreatic fistula when compared with pancreaticojejunostomy. Objective: The aim of this study was to compare the incidence of pancreatic fistula after pacreaticogastrostomy (PG) versus pancreaticojejunostomy (PJ) and analyze the risk factors associated with the development of fistula. Material and methods: 91 patients undergoing pancreaticoduodenectomy were evaluated; 43 with PG reconstruction and 48 with PJ reconstruction. Demographic and surgical data were evaluated and the incidence of pancreatic fistula with both techniques was compared Results: The incidence of fistula for the total series was 14.3% (n = 13) and 5 were clinically relevant. There were differences in age and pancreatic duct diameter < 3 mm between the groups. The incidence of fistula was similar in both groups (p = 0.478). Pancreatic duct diameter < 3 mm was the only significant predisposing factor for the development of fistula. Conclusion: In our series, and in coincidence with others, there were no differences in the incidence of pancreatic fistulas between PG and PJ. Practicing and mastering a repetitive, standardized technique would yield the best results.

ABSTRACT

INTRODUCCIÓN: Los carcinomas adenoneuroendocrinos mixtos (MANEC) son tipos de tumores bifásicos, reconocidos morfológicamente ante la presencia de una formación neoplásica constituida de manera simultánea por epitelio glandular y células neuroendocrinas. Dentro del tracto gastrointestinal, estas neoplasias predominan en el estómago o el colon. Solo 19 casos localizados en la ampolla de Vater han sido reportados por la literatura. OBJETIVO: Reportar un caso de MANEC; revisar la epidemiología, pronóstico y tratamiento de estos tumores. MATERIALES Y MÉTODO: Presentación de caso clínico de una paciente con diagnóstico de adenocarcinoma neuroendocrino mixto de la región ampular. DISCUSIÓN: La presentación clínica, el manejo y el pronóstico son similares al del adenocarcinoma ampular. Se diagnostican con el examen histopatológico de la muestra resecada. Ambos componentes deben ser histológicamente malignos, y cada uno de ellos debe representar al menos el 30% de la lesión. CONCLUSIÓN: Los MANEC ampulares son tumores poco comunes a nivel mundial, siendo éste el primer caso reportado en nuestro instituto.


INTRODUCTION: Mixed adenoneuroendocrine carcinomas (MANEC) are types of biphasic tumors, morphologically recognized in the presence of a neoplastic formation constituted simultaneously by glandular epithelium and neuroendocrine cells. Only 19 cases located in the ampulla of Vater have been reported in the literature. Within the gastrointestinal tract, these neoplasms predominate in the stomach or colon. AIM: Report a case of MANEC; review of the epidemiology, prognosis and treatment of these tumors. MATERIALS AND METHOD: Case presentation of a patient diagnosed with mixed adeno-neuroendocrine carcinoma of the ampullary region. DISCUSSION: The clinical presentation, management and prognosis are similar to ampullary adenocarcinoma. These tumors are diagnosed with a histopathological examination of the resected specimen. Both components must be histologically malignant, and each of them must represent at least 30% of the lesion. CONCLUSION: MANEC of the ampulla are rare tumors worldwide, being this case the first reported in our institute.

ABSTRACT

PURPOSE: Recent studies have analyzed the short-term clinical outcomes of ndovascular management. However, the long-term outcomes are unknown. This study aimed to investigate clinical outcomes after endovascular management for ruptured pseudoaneurysm in patients after pancreaticoduodenectomy (PD). METHODS: The medical records of 2,783 patients who underwent PD were retrospectively reviewed at a single center. Of 62 patients who received intervention after pseudonaeurysm rupture, 57 patients (91.9%) experienced eventual success of hemostasis. The patients were composed as follows: (embolization only [EMB], n = 30), (stent-graft placement only [STENT], n = 19) and (both embolization and stent-graft placement simultaneously or different times [EMB + STENT], n = 8). Long-term complications were defined as events that occur more than 30 days after the last successful endovascular treatment. RESULTS: Among 57 patients, short-term stent-graft related complications developed in 3 patients (5.3%) and clinical complication developed in 18 patients (31.5%). Nine (15.8%) had long-term stent-graft related complications, which involved partial thrombosis in 5 cases, occlusion in 3 cases and migration in 1 case. Except for 1 death, the remaining 8 cases did not experience clinical complications. The stent graft primary patency rate was 88.9% after 1 month, 84.2% after 1 year, and 63.2% after 2 years. Of 57 patients, 30 days mortality occurred in 8 patients (14.0%). CONCLUSION: After recovery from initial complication, most of patients did not experience fatal clinical complication during long-term follow-up. Endovascular management is an effective and safe management of pseudoaneurysm rupture after PD in terms of long-term safety.

ABSTRACT

PURPOSE: The purpose of this study was to investigate whether the indicators of nutritional risk screening tool are associated with postoperative complications following pancreaticoduodenectomy (PD). METHODS: We investigated whether nutritional risk is associated with postoperative complications based on the medical records of 128 patients who underwent PD from 2010. The tool was composed of 6 risk factors: albumin, total lymphocyte count, body mass index, weight loss, dietary intake loss, and nutritional symptoms. The patients were divided into 2 groups: a nutritional risk group and a nonrisk group. The rates of general complications and postoperative pancreatic fistula (POPF) were investigated according to this nutritional status. RESULTS: There were 65 patients who did not have any risk factors. However, 63 patients had one risk factor or more. In the nonrisk group, the overall complication rate and serious complication rate were 30.8% and 15.4%, respectively. If there were one or more risk factors, the overall and serious complication rates were 59.5% and 41.3%, respectively (P = 0.001 and P = 0.001, respectively). The rate of clinically relevant POPF (grade B or C) was 9.2% in the nonrisk group. However, this rate was 23.8% in the NRS risk group (P = 0.029). In multivariate analysis, the NRS risk group was a significant factor of clinically relevant POPF (odds ratio, 9.878; 95% confidence interval, 1.527–63.914; P = 0.016). CONCLUSION: There were statistically significant associations between complications and nutritional indicators. A comprehensive analysis of nutritional parameters will help predict postoperative complications.

ABSTRACT

PURPOSE: Many studies have concluded that cancer patients may have better outcomes when their surgery is performed in high-volume centers, especially when the procedure is pancreaticoduodenectomy (PD). However, some studies concluded that experienced surgeons or incorporation of expertise from high-volume centers may achieve satisfactory outcomes after PD in low-volume centers. METHODS: I retrospectively collected and analyzed the outcomes of PD for periampullary cancers treated with curative intent in my center. RESULTS: From August 2, 2005 to December 10, 2018, 160 pancreatic resections were done with curative intent in my center. The number of operations per year was 1 in 2005 and gradually increased to 21 in 2018. Thirty-day mortality was 0, and 90-day mortality was 1 (0.6%). Morbidity was found in 65 cases (40.6%). The median follow-up period was 23.2 months and 5-year survival rates were 28.5% for pancreas head cancer, 48.2% for distal CBD cancer, and 72.6% for AOV cancer. I divided patients into 2 groups by the number of annual operations, which is more than 21 per 2 years. The 2 groups showed no differences in terms of morbidity and mortality. CONCLUSION: A well-trained low-volume surgeon may perform PD safely at a well-equipped low-volume center.
