ABSTRACT

Las neoplasias de páncreas son una entidad poco frecuente en pediatría; el tumor pseudopapilar de páncreas (TSP) es el más comúnmente diagnosticado. Habitualmente, se localizan en la cabeza del páncreas. La cirugía de Whipple o pancreatoduodenectomía es la técnica elegida para el tratamiento de los tumores benignos o malignos de páncreas. Si bien la mortalidad conocida ha descendido en los últimos años, debido a la mayor experiencia de los cirujanos y al mejor cuidado pre- y posoperatorio, la morbilidad se ha mantenido elevada secundaria a las complicaciones asociadas. Dentro de estas se destacan retardo en el vaciamiento gástrico, colecciones intraabdominales, fístula pancreática, reestenosis del sitio quirúrgico y hemorragia pospancreatectomía. Se presenta el caso clínico de una niña de 13 años con diagnóstico de TSP que recibió tratamiento quirúrgico efectivo desde el punto de vista oncológico, pero que requirió una internación prolongada secundaria a las complicaciones quirúrgicas.


Pancreatic neoplasms are rare in pediatrics; the pseudopapillary tumor (PPT) of the pancreas is the most common. PPTs of the pancreas are usually located in the head of the pancreas. A pancreaticoduodenectomy or Whipple procedure is the technique of choice for the treatment of benign or malignant pancreatic tumors. Although mortality for this cause has decreased in recent years, due to the greater experience of surgeons and improved pre- and postoperative care, morbidity has remained high secondary to associated complications. These include delayed gastric emptying, intra-abdominal collections, pancreatic fistula, surgical site restenosis, and post-pancreatectomy hemorrhage. Here we describe the clinical case of a 13-year-old girl diagnosed with PPT of the pancreas who underwent an effective surgery in terms of cancer treatment, but who required a prolonged hospitalization secondary to surgical complications.

ABSTRACT

El carcinoma de células renales (CCR) a nivel mundial presenta una incidencia de 431.288 casos anuales, causando 179.368 muertes en 2020. Sin embargo, a pesar de su incidencia, el desarrollo de metástasis pancreática (MP) de un RCC es un hecho inusual. El objetivo de este manuscrito fue reportar el caso de una paciente con una MP metacrónica de un CCR. Se trata de una paciente de 56 años, sexo femenino, nefrectomizada derecha hace 132 meses por un CCR, en adyuvancia con inmunoterapia. En un control imagenológico de rutina, se le pesquisó una lesión de aspecto tumoral en el cuerpo y cola del páncreas. Se intervino quirúrgicamente, realizándose una pancreatectomía córporo-caudal con preservación esplénica. Evolucionó de forma satisfactoria, sin complicaciones, siendo dada de alta al 4º día de su cirugía. El informe del estudio de la pieza operatoria con estudio inmunohistoquímico concluyó que se trataba de una MP de CCR. La paciente se encuentra en buenas condiciones generales y reinició quimioterapia con anticuerpos monoclonales. El seguimiento frecuente y prolongado de pacientes con antecedentes de CCR, facilita un diagnóstico y tratamiento oportuno de MP facilitando el mejor pronóstico de los pacientes, con tasas más altas de supervivencia.


SUMMARY: Renal cell carcinoma (RCC) worldwide has an incidence of 431,288 cases per year, causing 179,368 deaths in 2020. However, despite its incidence, the development of pancreatic metastasis (MP) from RCC is unusual. The aim of this manuscript was to report the case of a patient with a PM of a RCC. This is a 56-year-old female patient, underwent right nephrectomy 132 months earlier for RCC. While she was in adjuvant immunotherapy, in a routine imaging control, it was found a tumor lesion in the body and the tail of the pancreas. So, she underwent surgery, performing a corpora-caudal pancreatectomy with splenic preservation. Postoperative evolution was correct, without complications, and she was discharged on the 4th day after surgery. The report of the study of the surgical piece with an immunohistochemical study included, conclusive of PM of RCC. Currently, the patient is in good general condition and restarted chemotherapy with monoclonal antibodies. Frequent and prolonged follow-up of patients with a history of RCC facilitates timely diag- nosis and treatment of PM, facilitating the best prognosis for patients, with higher survival rates.

ABSTRACT

ABSTRACT BACKGROUND: Para-aortic lymph nodes involvement in pancreatic head cancer has been described as an independent adverse prognostic factor. To avoid futile pancreatic resection, we systematically perform para-aortic lymphadenectomy as a first step. AIMS: To describe our technique for para-aortic lymphadenectomy. METHODS: A 77-year-old female patient, with jaundice and resectable pancreatic head adenocarcinoma, underwent pancreaticoduodenectomy associated with infracolic lymphadenectomy. RESULTS: The infracolic anterior technique has two main advantages. It is faster and prevents the formation of postoperative adhesions, which can make subsequent surgical interventions more difficult. CONCLUSIONS: We recommend systematic para-aortic lymphadenectomy as the first step of pancreaticoduodenectomy for pancreatic head adenocarcinoma by this approach.


RESUMO RACIONAL: O envolvimento dos gânglios linfáticos para-aórticos no câncer da cabeça do pâncreas tem sido descrito como um fator prognóstico adverso independente. Para evitar a ressecção pancreática inútil, realizamos sistematicamente linfadenectomia para-aórtica. OBJETIVOS: Descrever a técnica de linfadenectomia para-aórtica. MÉTODOS: Paciente do sexo feminino, 77 anos, com quadro de icterícia e adenocarcinoma da cabeça do pâncreas ressecável, submetida à duodenopancreatectomia associada à linfadenectomia infracólica. RESULTADOS: Esta técnica anterior infracólica tem duas vantagens principais: é mais rápida e evita a formação de aderências pós-operatórias, o que pode dificultar as intervenções cirúrgicas subsequentes. CONCLUSÕES: Recomendamos a linfadenectomia para-aórtica sistemática como o primeiro passo da duodenopancreatectomia para o adenocarcinoma da cabeça do pâncreas por esta abordagem.

ABSTRACT

El tumor pseudopapilar de páncreas, conocido como tumor de Frantz, es excepcional; comprende entre el 0.2 y 2.7 % de los carcinomas de páncreas. Su etiología es desconocida y predomina en mujeres jóvenes. Son tumores de bajo potencial maligno, que cursan asintomáticos y dan síntomas por compresión regional: dolor gravativo y/o masa abdominal palpable. La probabilidad de una forma definidamente maligna es de 15 %. Anatómicamente se localizan con mayor frecuencia en la cola del páncreas, seguido por la cabeza y el cuerpo. El tratamiento es la resección quirúrgica y su pronóstico es excelente, con sobrevida a 5 años de casi 100 %. El diagnóstico es anátomo-patológico, considerando el aspecto microscópico y el perfil inmunohistoquímico. Se presenta un caso de una mujer de 21 años, en la cual se realizó una cirugía de excéresis completa del tumor y que se mantiene a asintomática a 24 meses de operada.


Pseudo papillary tumor of the pancreas, also called Frantz´s tumor, is a very rare disease; between 0.2 and 2.7 % of pancreatic carcinomas. Ethiology is unknown; is observed in young women. It´s a tumors with low malignant potential, usually of asymptomatic evolution by long time and the symptoms are due to regional compression: pain or abdominal mass. The possibility of a malignant form is around 15 %. Anatomically, they are most frequently located in the tail of the pancreas, followed by the head and body. The treatment is the surgical resection; with an excellent prognosis and a 5-year survival almost 100 %. The diagnosis is with pathological study, considering the microscopic appearance and the immunohistochemical profile. Its perform an analysis of the literature and once case of a 21 years old, woman is reported. A complete resection surgery of the tumor was performed and remains asymptomatic at 24 months of follow-up.

ABSTRACT

OBJECTIVE@#To investigate the safety of laparoscopic pancreaticoduodenectomy (LPD) in elderly patients and the related risk factors admitted to the intensive care unit (ICU) after LPD.@*METHODS@#The perioperative data of patients who underwent LPD in Tianjin Medical University General Hospital from February 2017 to June 2023 were retrospectively collected, including basic data, preoperative laboratory indicators, intraoperative and postoperative indicators, pathological results (tumor size, lymph node dissection and pathological type), postoperative complications, ICU postoperative management and prognosis. The patients were divided into the elderly group (≥ 65 years) and the non-elderly group (< 65 years) according to age. Perioperative data between two groups were compared. Kaplan-Meier survival curve was drawn to analyze the survival rate of the elderly group and the non-elderly group, and the pancreatic head carcinoma group and other type of tumors group after LPD. Logistic regression was used to analyze the risk factors of ICU stay (length of ICU stay > 1 day) after LPD in elderly patients. The receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of this risk factor for ICU stay after LPD in elderly patients.@*RESULTS@#A total of 160 patients were enrolled, including 57 cases in the elderly group (17 cases of vascular reconstruction) and 103 cases in the non-elderly group (40 cases of vascular reconstruction). All patients underwent R0 resection and were transferred to the comprehensive ICU for treatment. The follow-up time of patients with malignant tumors was 43 (6, 72) months. The elderly group had significantly longer surgery time, postoperative hospital stay and oral feeding time than the non-elderly group, and the incidence of delayed gastric emptying (DGE) was significantly higher than that in the non-elderly group. There were no significant differences in intraoperative blood transfusion rate, intraoperative blood loss, pathological results, short-term and severe postoperative complications, reoperation rate and 90-day mortality between the two groups. In patients with vascular resection reconstruction, the intraoperative blood loss in the elderly group was significantly higher than that in the non-elderly group, and the operation time and postoperative hospital stay were significantly longer. During ICU, the acute physiology and chronic health evaluation II [APACHE II: 12 (9, 14) vs. 8 (7, 10)], sequential organ failure assessment [SOFA: 6 (4, 8) vs. 3 (2, 5)] within 24 hours after admission to ICU were significantly increased in the elderly group (both P < 0.05), the time of mechanical ventilation [hours: 12 (10, 15) vs. 9 (5, 13)] and the length of ICU stay [days: 2 (1, 2) vs. 1 (1, 1)] were significantly increased in the elderly group (both P < 0.05), and the proportion of multi-disciplinary team (MDT) was also significantly increased in the elderly group (33.3% vs. 17.4%, P < 0.05), there were no significant differences in the levels of hemoglobin (Hb), albumin, and blood lactic acid between the two groups. Logistic regression analysis showed that the APACHE II score was an independent risk factor for ICU stay after LPD in elderly patients (β = 1.737, P = 0.028). ROC curve showed that the prediction performance was the best when the APACHE II score was 13, with the sensitivity of 72.41% and the specificity of 96.43%, and the area under the ROC curve (AUC) of 0.884. The Kaplan-Meier survival curve showed that there were no significant difference in median survival time (months: 24.1 vs. 24.7) and 5-year survival rate (19.01% vs. 19.02%) between the elderly group (52 cases) and the non-elderly group (92 cases) among the 144 patients with malignant tumors (both P > 0.05). The median survival time in the pancreatic head carcinoma group was significantly shorter than that in the other tumors group (63 cases; months: 20.2 vs. 40.1, P < 0.05), 5-year survival rate was significantly lower than that in the other tumors group (21.98% vs. 30.91%, P < 0.05).@*CONCLUSIONS@#LPD is a safe and feasible treatment for elderly patients. APACHE II score has a certain predictive value for ICU stay after LPD in elderly patients.

ABSTRACT

As a severe malignant tumor of the digestive system,the highly invasive pancreatic cancer lacks typical preliminary symptoms. Rapid metastatic dissemination and difficulty in early-stage diagnosis preclude the chance of radical curative resection,hence resulting in a poor overall prognosis in most patients. In recent years,the wide application of the artificial intelligence(AI),represented by machine learning and deep learning,has developed rapidly in the field of medicine. All sorts of models based on AI have been applied to the screening, early diagnosis, treatment, prognosis prediction of patients with pancreatic cancer.Three-dimentional visualization and augmented reality navigation technologies have also been developed and applied in pancreatic cancer surgery.This paper reviews the status quo of AI application in pancreatic cancer from various aspects,and anticipates its future application prospects.

ABSTRACT

Objective: To explore the outcome of different treatment strategies in patients with pancreatic cancer with synchronous liver metastasis (sLMPC). Methods: A retrospective analysis of the clinical data and treatment results of 37 patients with sLMPC treated in China-Japan Friendship Hospital was performed from April 2017 to December 2022. A total of 23 males and 14 females were included,with an age(M(IQR)) of 61 (10) years (range: 45 to 74 years). Systemic chemotherapy was carried out after pathological diagnosis. The initial chemotherapy strategy included modified-Folfirinox, albumin paclitaxel combined with Gemcitabine, and Docetaxel+Cisplatin+Fluorouracil or Gemcitabine with S1. The possibility of surgical resection (reaching the standards of surgical intervention) was determined after systemic treatment,and the chemotherapy strategy was changed in the cases of failed initial chemotherapy plans. The Kaplan-Meier method was used to estimate the overall survival time and rate,while Log-rank and Gehan-Breslow-Wilcoxon tests were used to compare the differences of survival curves. Results: The median follow-up time for the 37 sLMPC patients was 39 months,and the median overall survival time was 13 months (range:2 to 64 months) with overall survival rates of 1-,3-,and 5-year of 59.5%,14.7%,and 14.7%,respectively. Of the 37 patients,97.3%(36/37) initially received systemic chemotherapy, 29 completed more than four cycles,resulting in a disease control rate of 69.4% (partial response in 15 cases,stable disease in 10 cases,and progressive disease in 4 cases). In the 24 patients initially planned for conversion surgery,the successful conversion rate was 54.2% (13/24). Among the 13 successfully converted patients,9 underwent surgery and their treatment outcomes were significantly better than those (4 patients) of those who did not undergo surgery (median survival time not reached vs. 13 months,P<0.05). Regarding the 9 patients whose conversion was unsuccessful, no significant differences were observed in median survival time between the surgical group (4 cases) and the non-surgical group (5 cases) (P>0.05). In the allowed-surgery group(n=13),the decreased in pre-surgical CA19-9 levels and the regression of liver metastases were more significant in the successful conversion sub-group than in the ineffective conversion sub-group;however, no significant differences were observed in the changes in primary lesion between the two groups. Conclusion: For highly selective patients with sLMPC who achieve partial response after receiving effective systemic treatment,the adoption of an aggressive surgical treatment strategy can significantly improve survival time;however, surgery dose not provide such survival benefits in patients who do not achieve partial response after systemic chemotherapy.

ABSTRACT

Objective: To explore the development of the pancreatic surgeon technique in a high-volume center. Methods: A total of 284 cases receiving pancreatic surgery by a single surgeon from June 2015 to December 2020 were retrospectively included in this study. The clinical characteristics and perioperative medical history were extracted from the medical record system of Zhongshan Hospital,Fudan University. Among these patients,there were 140 males and 144 females with an age (M (IQR)) of 61.0 (16.8) years(range: 15 to 85 years). The "back-to-back" pancreatic- jejunal anastomosis procedure was used to anastomose the end of the pancreas stump and the jejunal wall. Thirty days after discharge,the patients were followed by outpatient follow-up or telephone interviews. The difference between categorical variables was analyzed by the Chi-square test or the CMH chi-square test. The statistical differences for the quantitative data were analyzed using one-way analysis of variance or Kruskal-Wallis H test and further analyzed using the LSD test or the Nemenyi test,respectively. Results: Intraoperative blood loss in pancreaticoduodenectomy between 2015 and 2020 were 300,100(100),100(100),100(0),100(200) and 150 (200) ml,respectively. Intraoperative blood loss in distal pancreatectomy was 250 (375),100 (50),50 (65), 50 (80),50 (50),and 50 (100) ml,respectively. Intraoperative blood loss did not show statistical differences in the same operative procedure between each year. The operative time for pancreaticoduodenectomy was respectively 4.5,5.0(2.0),5.5(0.8),5.0(1.3),5.0(3.3) and 5.0(1.0) hours in each year from 2015 to 2020,no statistical differences were found between each group. The operating time of the distal pancreatectomy was 3.8 (0.9),3.0 (1.5),3.0 (1.8),2.0 (1.1),2.0 (1.5) and 3.0(2.0) hours in each year,the operating time was obviously shorter in 2018 compared to 2015 (P=0.026) and 2020 (P=0.041). The median hospital stay in 2020 for distal pancreatectomy was 3 days shorter than that in 2019. The overall incidence of postoperative pancreatic fistula gradually decreased,with a incident rate of 50.0%,36.8%,31.0%,25.9%,21.1% and 14.8% in each year. During this period,in a total of 3,6,4,2,0 and 20 cases received laparoscopic operations in each year. The incidence of clinically relevant pancreatic fistula (grade B and C) gradually decreased,the incident rates were 0,4.8%,7.1%,3.4%,4.3% and 1.4%,respectively. Two cases had postoperative abdominal bleeding and received unscheduled reoperation. The overall rate of unscheduled reoperation was 0.7%. A patient died within 30 days after the operation and the overall perioperative mortality was 0.4%. Conclusion: The surgical training of a high-volume center can ensure a high starting point in the initial stage and steady progress of pancreatic surgeons,to ensure the safety of pancreatic surgery.

ABSTRACT

Resumen Introducción: Los tumores periampulares se definen como lesiones ubicadas en un radio de 2 cm alrededor de la ampolla de Vater, constituidos por 4 tipos de neoplasias con una alta tasa de malignidad que pueden originarse en páncreas, ampolla, vía biliar distal o duodeno. El manejo quirúrgico a través de la pancreatoduodenectomía sigue siendo la mejor elección en términos de resección curativa. Objetivo: Caracterizar los tumores peri-ampulares tratados en nuestra institución y que fueron llevados a pancreatoduodenectomía, asociando la relación entre tipo de tumor y complicaciones posoperatorias. Material y Método: Estudio transversal, retrospectivo y observacional con seguimiento a 45 pacientes sometidos a pancreatoduodenectomía en el Hospital Internacional de Colombia - Fundación Cardiovascular entre enero de 2011 y marzo de 2020 con diagnostico histopatológico de tumor peri-ampular. Resultados: Se realizaron 75 pancreatoduodenectomía de las cuales 45 pacientes presentaron tumor peri-ampular, siendo de origen pancreático en un 44%, seguido de ampolla 40%, vía biliar distal 8,8% y duodenal 6,6%. Las complicaciones posoperatorias más frecuentes fueron fístula pancreática y vaciamiento gástrico retardado. Falleció 1 paciente. Conclusión: La pancreatoduodenectomía es un procedimiento con alta morbilidad. Gracias al avance tecnológico, el diagnóstico de patología peri ampular es cada vez más exacto. El tipo de tumor peri-ampular puede influir no solo en su pronóstico, sino también en su morbilidad posquirúrgica.


Introduction: Periampullary tumors are defined as lesions that are located in a radius of 2 centimeters around the ampulla of Vater, constituted by 4 types of neoplasms with a high rate of malignancy originated in the pancreas, ampulla, distal bile duct or duodenum. Surgical management through the pancreatoduodenectomy remains the best choice in terms of curative resection. Objetive: To characterize periampullary tumors treated in our institution with pancreatoduodenectomy, associating the relationship between tumor type and postoperative complications. Material and Method: Cross-sectional, retrospective, observational study with a follow-up of 45 patients underwent pancreatoduodenectomy in the Hospital Internacional de Colombia - Fundación Cardiovascular between January 2011 and March 2020 with histopathological diagnosis of periampullary tumor. Results: Were performed 75 pancreatoduodenectomies, 45 patients presented with Periampullary tumor, 44% being of pancreatic origin, followed by ampulla 40%, distal bile duct 8.8% and duodenal 6.6%. Most frequent postoperative complications were pancreatic fistula and delayed gastric emptying. Mortality was of 1 patient. Conclusión: Pancreatoduodenectomy is a procedure with a high morbidity rate. Thanks to technological advances, the diagnosis of periampullary pathology is increasingly accurate. The type of periampullary tumor may influence not only in its prognosis, but also in its post-surgical morbidity.

ABSTRACT

Objective: To evaluate the safety and feasibility of laparoscopic surgery after neoadjuvant chemotherapy for pancreatic cancer. Methods: Clinical data of 8 patients underwent laparoscopic surgery after neoadjuvant chemotherapy for pancreatic cancer at Fudan University Shanghai Cancer Center from September 2019 to June 2020 were reviewed retrospectively. There were 5 males and 3 females,aged from 47 to 72 years old. All patients underwent abdominal enhanced CT and PET-CT before operation to accurately evaluate the tumor stage and exclude distant metastasis. Results: Neoadjuvant chemotherapy with AG regimen(gemcitabine 1 000 mg/m2 and albumin bound paclitaxel 125 mg/m2) was received for 2 to 6 cycles before surgery. All 8 patients successfully completed the operation,including 5 cases of pancreaticoduodenectomy,2 cases of radical antegrade modular pancreatosplenectomy(RAMPS),and 1 case of total pancreatectomy. No conversion to laparotomy or laparoscopic assisted surgery. The operation time was 240 to 450 minutes,the blood loss was 100 to 500 ml,the postoperative length of stay was 10 to 16 days. During the follow-up period up to December 31, 2020, there was 1 case suffered grade B pancreatic leakage and abdominal infection. The numbers of resected lymph nodes were 9 to 31. All patients received R0 resection. The follow-up times were 4.5 to 9.5 months. One patient underwent RAMPS was diagnosed as liver metastasis after 2 months of the operation,and the other 7 patients still survived without tumor recurrence. Conclusion: Minimally invasive surgery of pancreatic cancer after neoadjuvant chemotherapy is safe and feasible in experienced pancreatic minimally invasive centers.

ABSTRACT

Objective: To compare and analyze the clinical efficacy of pancreaticoduodenectomy for distal bile duct cancer and pancreatic head cancer. Methods: Clinical data of 1 005 patients who underwent pancreaticoduodenectomy and postoperative pathological examination confirmed the diagnosis of distal bile duct cancer and pancreatic head cancer at the Pancreas Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2020 were analyzed retrospectively. There were 112 cases in the distal bile duct cancer group, 71 males and 41 females,with age (M(IQR)) of 65(15) years(range: 40 to 87 years); 893 cases in the pancreatic head cancer group, 534 males and 359 females,with age of 64(13)years(range: 16 to 91 years). The differences between clinicopathological characteristics and postoperative overall survival of the two groups were analyzed by χ2 test, Fisher's exact probability method, rank sum test or log-rank test, respectively. The difference in postoperative overall survival between the two groups was compared using Kaplan-Meier method after propensity score matching (1∶1). Results: Compared with the pancreatic head cancer group,the distal bile duct cancer group had shorter operative time (240.0(134.0) minutes vs. 261.0(97.0) minutes, Z=2.712, P=0.007),less proportion of combined venous resection (4.5% (5/112) vs. 19.4% (173/893), χ²=15.177,P<0.01),smaller tumor diameter (2.0(1.0) cm vs. 3.0(1.5) cm,Z=10.567,P<0.01),higher well/moderate differentiation ratio (51.4% (56/112) vs. 38.0% (337/893), χ²=7.328, P=0.007),fewer positive lymph nodes (0(1) vs. 1(3), Z=5.824, P<0.01),and higher R0 resection rate (77.7% (87/112) vs. 38.3%(342/893), χ²=64.399, P<0.01),but with a higher incidence of overall postoperative complications (50.0% (56/112) vs. 36.3% (324/892), χ²=7.913,P=0.005),postoperative pancreatic fistula (28.6% (32/112) vs. 13.9% (124/893), χ²=16.318,P<0.01),and postoperative abdominal infection (21.4% (24/112) vs. 8.6% (77/892), χ²=18.001,P<0.01). After propensity score matching, there was no statistical difference in postoperative overall survival time between patients in the distal bile duct cancer group and the pancreatic head cancer group (50.6 months vs. 35.1 months,Z=1.640,P=0.201),and multifactorial analysis showed that tumor site was not an independent risk factor affecting the prognosis of patients in both groups after matching (HR=0.73,95%CI:0.43 to 1.23,P=0.238). Conclusions: Patients with distal bile duct cancer are more likely to benefit from early diagnosis and surgical treatment than patients with pancreatic head cancer,but with a relative higher postoperative complication rates. The different tumor origin site is not an independent risk factor for prognosis of patients with distal bile duct cancer and pancreatic head cancer after propensity score matching.

ABSTRACT

Objective: To identify the risk factors of newly developed nonalcoholic fatty liver disease(NAFLD) after pancreaticoduodenectomy(PD). Methods: The clinical data of 130 patients who had undergone PD at Department of Hepatopancreatobiliary Surgery, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University from June 2018 to December 2020 were collected retrospectively. There were 74 males and 56 females, with age(M(IQR)) of 62(16) years (range: 22 to 84 years). Twenty-nine patients who developed NAFLD were divided into NAFLD group and 101 patients who did not suffer NAFLD were divided into no NAFLD group. Observation indications included:(1)preoperative demographics,intraoperative and postoperative characteristics; (2)the risk factors of newly developed NAFLD after PD. Count data were analyzed using χ2 test or Fisher's exact test. Measurement data were analyzed by student t test or Mann-Whitney U test. Multivariate analysis was performed using Logistic regression model with a stepwise forward approach. Results: All 130 patients successfully underwent PD and 29 cases(22.3%) developed NAFLD in 6 months after PD. The results of univariate analysis showed that gender,diabetic mellitus,the level of triglyceride preoperatively,and pancreatic ductal adenocarcinoma were the related factors of the development of NAFLD after PD(t=-2.655, χ²=4.563,U=-2.192,χ²=7.044;all P<0.05).Multivariate analysis revealed that gender,body mass index and pancreatic ductal adenocarcinoma were independent risk factors for the development of NAFLD after PD(OR=2.849,1.214,4.165,all P<0.05). Conclusion: Gender, body mass index and pancreatic ductal adenocarcinoma were independent risk factors for the development of NAFLD after PD.

ABSTRACT

Objective: To examine the clinical effect of minimally invasive duodenum preserving pancreatic head resection(DPPHR) for benign and pre-malignant lesions of pancreatic head. Methods: The clinical data of patients with diagnosis of benign or pre-malignant pancreatic head tumor were retrospectively collected and analyzed,all of them underwent laparoscopic or robotic DPPHR between October 2015 and September 2021 at Division of Gastrointestinal and Pancreatic surgery,Zhejiang Provincial People's Hospital. Thirty-three patients were enrolled with 10 males and 23 females. The age(M(IQR)) was 54(32) years old(range: 11 to 77 years old) and the body mass index was 21.9(2.9)kg/m2(range: 18.1 to 30.1 kg/m2). The presenting symptoms included abdominal pain(n=12), Whipple triad(n=2), and asymptomatic(n=19). There were 7 patients with hypertension and 1 patient with diabetes mellitus. There were 19 patients who were diagnosed as American Society of Anesthesiologists class Ⅰ and 14 patients who were diagnosed as class Ⅱ. The student t test,U test, χ2 test or Fisher exact test was used to compare continuous data or categorized data,respectively. All the perioperative data and metabolic morbidity were analyzed and experiences on minimally invasive DPPHR were concluded. Results: Fourteen patients underwent laparoscopic DPPHR,while the rest of 19 patients received robotic DPPHR. Indocyanine green fluorescence imaging was used in 19 patients to guide operation. Five patients were performed pancreatico-gastrostomy and the rest 28 patients underwent pancreaticojejunostomy. Pathological outcomes confirmed 9 solid pseudo-papillary neoplasms, 9 intraductal papillary mucinous neoplasms, 7 serous cystic neoplasms, 6 pancreatic neuroendocrine tumors, 1 mucous cystic neoplasm, 1 chronic pancreatitis. The operative time was (309.4±50.3) minutes(range:180 to 420 minutes),and the blood loss was (97.9±48.3)ml(range:20 to 200 ml). Eighteen patients suffered from postoperative complications,including 3 patients experienced severe complications(Clavien-Dindo Grade ≥Ⅲ). Pancreatic fistula occurred in 16 patients,including 8 patients with biochemical leak,7 patients with grade B pancreatic fistula and 1 patient with grade C pancreatic fistula. No one suffered from the duodenal necrosis and none perioperative death was occurred. The length of hospital stay was 14(7) days (range:6 to 87 days). The follow-up was 22.6(24.5)months(range:2 to 74 months). None suffered from recurrence or metastasis. During the follow-up,all the patients were free of refractory cholangitis. Moreover,in the term of endocrine dysfunction,no postoperative new onset of diabetes mellitus were observed in the long-term follow-up. However,in the view of exocrine insufficiency,pancreatic exocrine insufficiency and non-alcoholic fatty liver disease (NAFLD) was complicated in 2 and 1 patient,respectively,with the supplement of pancreatic enzyme,steatorrhea and weight loss relieved,but NAFLD was awaited to be seen. Conclusions: Minimally invasive DPPHR is feasible and safe for benign or pre-malignant lesions of pancreatic head. Moreover,it is oncological equivalent to pancreaticoduodenectomy with preservation of metabolic function without refractory cholangitis.

ABSTRACT

Pancreatic cancer is a malignant tumor with very poor prognosis. In the past decade, the surgical technique has made significant progress, but it has not brought desired effect in improving the survival outcome of pancreatic cancer patients. With the development of the concept of cancer treatment and the emergence of precision medicine, the surgical centered multidisciplinary treatment and collaborative diagnosis and treatment mode has gradually become the mainstream. Accurate preoperative assessment of pancreatic cancer has become a breakthrough for further improving the prognosis of patients with pancreatic cancer. From the perspective of precise assessment, this paper mainly summarized the status and progress on the following four aspects: the preoperative diagnosis and staging, the resectability evaluation, the neoadjuvant therapy strategy and efficacy evaluation of neoadjuvant therapy in pancreatic cancer, and also discussed the shortcomings and challenges in the field of precise assessment, finally in order to make the preoperative assessment of pancreatic cancer more precise and standard, and to provide useful reference for future research work.

ABSTRACT

Resumen El adenocarcinoma ductal de páncreas es una enfermedad agresiva asociada con pobres resultados de supervivencia a largo plazo. La resección quirúrgica y los nuevos tratamientos oncológicos pe rioperatorios han logrado mejorar la supervivencia de estos pacientes en la experiencia internacional. En este estudio retrospectivo se analiza la supervivencia global y la libre de enfermedad de todos los pacientes operados por cáncer de páncreas en el Hospital Italiano de Buenos Aires de enero 2010 a enero 2020. Se identificaron 242 pacientes con resecciones pancreáticas por adenocarcinoma de páncreas o carcinoma indiferenciado. La supervivencia global mediana fue de 22.8 meses (IC 95%: 19.5-29) y la tasa de supervivencia global a 1, 3 y 5 años fue de 72%, 32.5% y 20.8% respectivamente. La supervivencia libre de enfermedad mediana fue de 13.8 meses (IC 95%: 12-17.6) y la tasa de supervivencia libre de enfermedad a 1, 3 y 5 años fueron de 56.1%, 21.8% y 19.4% respectivamente. El grupo de pacientes que logró completar el tratamiento adyuvante mostró una mayor supervivencia global (p<0.0001).


Abstract Pancreatic cancer is an aggressive disease associated with poor results regarding long term survival. Surgical treatment along with new onco logic treatments have improved the survival of these patients in international experience reports. The aim of this study was to describe overall survival and disease-free survival after pancreatectomy for pancreatic ductal adenocarcinoma. A retrospective study of consecutive patients undergoing pancreatic resection due to PDAC or undifferentiated carcinoma from January 2010 to January 2020 in a single tertiary center was performed. Overall, 242 patients underwent complete pancreatic resections for pancreatic ductal adenocarcinoma or undifferentiated carcinoma. Median overall survival was 22.8 months (95% CI: 19.5-29) and survival at 1, 3 and 5 years were 72%, 32.5% and 20.8% respectively. The median disease-free survival was 13.8 months (95% CI: 12-17.6) and 1, 3- and 5-years disease-free survival were 56.1%, 21.8% and 19.4% respectively. The groups of patients that completed adjuvant treatment showed a better overall survival (p < 0.0001).

ABSTRACT

RESUMEN El páncreas ectópico es una entidad poco común. Como tumor submucoso de origen congénito, frecuentemente presenta un curso asintomático, aunque con posibles complicaciones. Su diagnóstico de certeza se basa en la endoscopia, el ultrasonido endoscópico y la histología, que permiten adoptar una conducta expectante o quirúrgica. El paciente estudiado presentó un páncreas ectópico localizado en antro gástrico asociado a síntomas de reflujo gastroesofágico rebeldes a tratamiento, los cuales motivaron el estudio endoscópico, con el consecuente hallazgo de dicha entidad (AU).


ABSTRACT Ectopic pancreas is a little common entity. As congenital-originated sub mucous tumor, it frequently presents an asymptomatic course, though with possible complications. Its definitive diagnosis is based in the endoscopy, endoscopic ultrasound and histology, allowing to adopt an expectant or surgical behavior. The current patient presented an unresponsive-to-treatment ectopic pancreas located in the gastric antrum associated to gastro-esophageal reflux symptoms. This motivated the endoscopic study consequently leading to finding this entity (AU).

ABSTRACT

El tumor sólido pseudopapilar del páncreas, conocido también como tumor de Frantz, es una enfermedad rara: neoplasia bien delimitada, de lento crecimiento, no agresiva pero maligna, habitualmente con pronóstico favorable. El tratamiento de elección es quirúrgico. Aunque algunos de ellos son agresivos a nivel local, la mayoría de los pacientes se curan con la resección completa del tumor. Se reportó el caso de una mujer de 30 años, ingresada en el Servicio de Cirugía General del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, con diagnóstico presuntivo clínico e imagenológico, de tumor pseudopapilar sólido del páncreas, con confirmación histológica tras la resección quirúrgica. Este infrecuente tumor debe ser considerado en el diagnóstico diferencial de los tumores pancreáticos, fundamentalmente en mujeres jóvenes(AU)


The solid pseudo-papillary carcinoma, also known as Frantz´s tumor, is a rare disease. It is a well-defined neoplasia, of low growth, non-aggressive but malignant, usually with a favorable prognosis. The elective treatment is the surgery. Although some of them are locally aggressive, most patients are healed with the complete tumor resection. The authors reported the case of a woman, aged 30 years who entered the Service of General Surgery of the University Hospital Comandante Faustino Pérez Hernández, with a presumptive clinical and imaging diagnosis of pancreas solid pseudo-papillary tumor, histologically confirmed after surgical resection. This infrequent tumor should be taken into account in the differential diagnosis of pancreatic tumors, mainly in young women(AU)

ABSTRACT

RESUMEN Introducción: los tumores de la encrucijada duodeno-bilio-pancreática o periampulares corresponden a un grupo heterogéneo de tumores. Se originan dentro de los 2 cm de la papila duodenal mayor. En los tumores irresecables, el tratamiento debe estar dirigido a la paliación más efectiva. El tratamiento quirúrgico paliativo va dirigido a resolver la obstrucción biliar, duodenal y el dolor, con el fin de optimizar la calidad de vida de los pacientes. Objetivo: describir el comportamiento del tratamiento quirúrgico paliativo de los tumores periampulares. Materiales y métodos: se realizó una investigación observacional, descriptiva y prospectiva con los pacientes con tumor periampular irresecable tributarios a tratamiento quirúrgico paliativo, en el Servicio de Cirugía General del Hospital Universitario "Comandante Faustino Pérez Hernández", en la ciudad de Matanzas, desde enero del 2010 hasta diciembre del 2019. Resultados: el tumor de páncreas fue el más representado. Todos los pacientes fueron tributarios de derivación biliar quirúrgica paliativa, sin embargo, la derivación gástrica se realizó solo con confirmación endoscópica de infiltración tumoral u obstrucción duodenal y la esplacnicectomía química, siempre que fue factible técnicamente o las condiciones del paciente lo permitieron. La hepaticoyeyunostomía en Y de ROUX fue la derivación biliar de elección. La principal complicación quirúrgica fue la sepsis provocando las muertes. Conclusiones: la paliación quirúrgica es la alternativa de elección con mejores resultados a largo plazo, en los tumores periampulares irresecables con buen estado general, lo que contribuye a una mejor calidad de vida (AU).


ABSTRACT Introduction: the tumors of the duodenal-biliary-pancreatic junction or periampullary tumors correspond to a heterogeneous group of tumor. They originate inside the 2 cm of the major duodenal papilla. In unresectable tumors, the treatment should be intended for the most effective palliation. The surgical palliative treatment is intended for solving biliary, duodenal obstruction, and pain, with the aim of optimizing patients' life quality. Objective: to describe the behavior of the periampullary tumors palliative surgical treatment. Materials and methods: a prospective, descriptive, observational research was carried out in patients with unresectable periampullary tumor tributary to palliative surgical treatment, in the Service of General Surgery of the University Hospital "Comandante Faustino Perez Hernandez", of Matanzas, from January 2010 to December 2019. Results: pancreas tumor was the most represented one. All patients were tributary to biliary palliative surgical derivation, however, gastric derivation was performed only with endoscopic confirmation of tumor infiltration or duodenal obstruction, and chemical splanchnicectomy whenever it was technically feasible and the patient's conditions allowed it. Roux's Y-shaped hepaticojejunostomy was the elective biliary derivation. The main surgical complication was sepsis provoking deaths. Conclusions: surgical palliation is the election alternative with long- term better outcomes, in unresectable periampullary tumors with a good general status, contributing to better life quality (AU).

ABSTRACT

ABSTRACT Objective: to describe the implications of the diagnosis and treatment of non-inflammatory pancreatic cysts in a series of patients. Methods: we included patients with pancreatic cysts ≥1.0 cm, excluding those with a presumptive diagnosis of a pseudocyst. Imaging tests, echoendoscopy, and histopathology determined the diagnosis of the type of cyst. We applied the guidelines of the International Association of Pancreatology, with some modifications, in patients with mucinous or indeterminate lesions. Results: 97 adult patients participated in the study. A cystic neoplasm of the pancreas was diagnosed in 82.5% of cases. Diagnosis was mainly made by magnetic resonance (46% of cases). The two most common diagnoses were intraductal papillary mucinous neoplasm (43.3%) and serous cystadenoma (26%). Twenty-nine patients underwent surgery (33.3%). The most common surgical procedure was distal pancreatectomy associated with splenectomy in 19 cases (65.5%). Among the operated patients, 11 were diagnosed with cancer. None of the followed, non-operated patients had a diagnosis of cancer. Conclusions: magnetic resonance showed good accuracy, particularly in the diagnosis of intraductal papillary mucinous neoplasm. The guidelines of the International Association of Pancreatology, as applied in this study, showed a negative predictive value for cancer of 100%. A development of better diagnostic tests can reduce the number of unnecessary operations.


RESUMO Objetivo: descrever as implicações do diagnóstico e tratamento dos cistos não inflamatórios do pâncreas em série de pacientes. Metódos: foram incluídos pacientes com cisto de pâncreas ≥1,0cm excluindo aqueles com diagnóstico presuntivo de pseudocisto. Exames de imagem, ecoendoscopia e anatomia-patológica determinaram o diagnóstico do tipo de cisto. As diretrizes da Associação Internacional de Pancreatologia foram aplicadas, com algumas modificações, nos pacientes com lesões mucinosas ou indeterminadas. Resultados: noventa e sete pacientes adultos participaram do estudo. A neoplasia cística de pâncreas foi diagnosticada em 82,5% dos casos. O diagnóstico foi feito principalmente por ressonância magnética (46% dos casos). Os dois diagnósticos mais frequentes foram a neoplasia papilar intraductal mucinosa (43,3%), e o cistoadenoma seroso (26%). Vinte e nove pacientes foram submetidos a operação (33,3%). O procedimento cirúrgico mais comum foi a pancreatectomia corpo-caudal associada à esplenectomia em 19 casos (65,5%). Entre os pacientes operados, 11 tiveram o diagnóstico de câncer. Nenhum dos pacientes seguidos teve o diagnóstico de câncer. Conclusões: a ressonância magnética apresentou boa acurácia, particularmente no diagnóstico da neoplasia papilar intraductal mucinosa. As diretrizes da Associação Internacional de Pancreatologia da forma que foram aplicadas no presente estudo, mostraram valor preditivo negativo para o câncer de 100%. O desenvolvimento de estratégias diagnósticas com melhor acurácia podem reduzir o número de cirurgias desnecessárias.
