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

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

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

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

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: Laparoscopic distal pancreatectomy (LDP) has been widely performed for solid pseudopapillary neoplasm (SPN) involving the body or tail of the pancreas. However, it has not been established whether spleen preservation in LDP is oncologically safe for the treatment of SPN with malignant potential. In this study, we compared the short- and long-term outcomes between patients with SPN who underwent laparoscopic spleen-preserving distal pancreatectomy (LSPDP) vs laparoscopic distal pancreatectomy with splenectomy (LDPS). METHODS: We retrospectively reviewed the medical records of 46 patients with SPN who underwent LDP between January 2005 and November 2016. Patients were divided into 2 groups according to spleen preservation: the LSPDP group (n=32) and the LDPS group (n=14). Clinicopathologic characteristics and perioperative outcomes were compared between groups. RESULTS: There were no significant differences in pathologic variables, including tumor size, tumor location, node status, angiolymphatic invasion, or perineural invasion between groups. Median operating time was significantly longer in the LSPDP group vs the LDPS group (243 vs 172 minutes; p=0.006). Estimated intraoperative blood loss was also significantly greater in the LSPDP group (310 vs 167 ml; p=0.063). There were no significant differences in incidence of postoperative complications (≥ Clavien-Dindo class IIIa) or pancreatic fistula between groups. After a median follow-up of 35 months (range, 3S153 months), there was no recurrence or disease-specific mortality in either group. CONCLUSION: The results show that LSPDP is an oncologically safe procedure for SPN involving the body or tail of the pancreas.

ABSTRACT

BACKGROUND/AIMS: We investigated the effect of preoperative malnutrition on postoperative surgical outcomes in elderly patients undergoing pancreatoduodenectomy for periampullary neoplasms. METHODS: This prospective cohort study enrolled 154 patients aged ≥65 years with periampullary neoplasms. Using the Mini Nutritional Assessment tool, patients were categorized into three groups according to their preoperative nutritional status: well-nourished (13.0%), at-risk-of-malnutrition (59.7%), and malnourished (27.3%). RESULTS: Significant intergroup differences were observed in preoperative body mass index (25.6±2.4 kg/m² [well-nourished] vs 23.4±2.6 kg/m² [at-risk-of-malnutrition] vs 21.1±2.8 kg/m² [malnourished], p<0.001). The overall morbidity significantly differed between the well-nourished and malnourished groups (20% vs 50.0%, p=0.024). The rates of clinically significant postoperative pancreatic fistula were significantly different among groups (p=0.035). Univariate and multivariate analyses showed that the at-risk-of-malnutrition or malnourished status (hazard ratio [HR], 3.45; p=0.037) and intraoperative blood loss (HR, 1.01; p=0.040) significantly affected the overall postoperative morbidity in elderly patients. CONCLUSIONS: Before surgery, 87.0% of patients were classified into the at-risk-of-malnutrition or malnourished group. Compared with well-nourished patients, patients with nutritional issues showed a higher overall surgical morbidity. Improved preoperative nutritional status leads to favorable surgical outcomes in elderly patients.

ABSTRACT

The International Study Group for Pancreatic Fistula (ISGPF) made the first attempt to standardize the outcome measure of fistulas in the field of pancreatic surgery by publishing the definition and classification of postoperative pancreatic fistulas (POPFs) in 2005. POPFs were determined by any measurable volume of fluid output via an operatively placed drain with amylase activity greater than three times the upper normal serum value. Taking into account more than 10 years of reported experience worldwide, the updated definition published in 2016 by the reconvened International Study Group for Pancreatic Surgery (ISGPS) attempted to overcome the limits of the previous classification. The crucial concept of POPF clinical significance was introduced by eliminating grade A from the fistula scenario. The wider use of interventional procedures has also made it necessary to recode grade C POPFs, which now have clearer boundaries, toward the worst end of the severity scale. Grade B still represents the most prevalent and heterogeneous category of POPFs, both in terms of clinical burden and management. In the near future, further efforts will be required to better stratify grade B POPFs to standardize treatment strategies and compare outcomes among institutions.

ABSTRACT

BACKGROUND/AIMS: Acute pancreatitis complicated by walled-off necrosis (WON) is associated with high morbidity and mortality, and if infected, typically necessitates intervention. Clinical outcomes of infected WON have been described as poorer than those of symptomatic sterile WON. With the evolution of minimally invasive therapy, we sought to compare outcomes of infected to symptomatic sterile WON. METHODS: We performed a retrospective cohort study examining patients who were undergoing dual-modality drainage as minimally invasive therapy for WON at a high-volume tertiary pancreatic center. The main outcome measures included mortality with a drain in place, length of hospital stay, admission to intensive care unit, and development of pancreatic fistulae. RESULTS: Of the 211 patients in our analysis, 98 had infected WON. The overall mortality rate was 2.4%. Patients with infected WON trended toward higher mortality although not statistically significant (4.1% vs 0.9%, p=0.19). Patients with infected WON had longer length of hospitalization (29.8 days vs 17.3 days, p<0.01), and developed more spontaneous pancreatic fistulae (23.5% vs 7.8%, p<0.01). Multivariate analysis showed that infected WON was associated with higher odds of spontaneous pancreatic fistula formation (odds ratio, 2.65; 95% confidence interval, 1.20 to 5.85). CONCLUSIONS: This study confirms that infected WON has worse outcomes than sterile WON but also demonstrates that WON, once considered a significant cause of death, can be treated with good outcomes using minimally invasive therapy.

ABSTRACT

Endoscopic ultrasound (EUS)-guided transgastric drainage has been performed as a less invasive procedure for pancreatic fistulas and intra-abdominal abscesses occurring after surgery in recent years. However, there are no reports of EUS-guided transgastric drainage of intra-abdominal abscesses following gastrectomy. This case report describes 2 patients who developed an intra-abdominal abscess following gastrectomy and underwent EUS-guided transgastric drainage. Both patients underwent laparoscopy-assisted distal gastrectomy with Billroth-I reconstruction for gastric cancer. The intra-abdominal abscesses were caused by postoperative pancreatic fistula that developed following gastrectomy. One patient underwent naso-cystic drainage and the other underwent only a needle puncture of the abscess cavity. EUS-guided drainage was performed safely and effectively, although 1 patient developed gastroduodenal anastomotic leakage related to this procedure. In summary, EUS-guided transgastric drainage is safe and technically feasible even in post-gastrectomy patients. However, it is necessary to be careful if this procedure is performed in the early period following gastrectomy.

ABSTRACT

PURPOSE: We have summarized the experience of our institution related to what treatment has been performed in patients with pancreatic fistula and their outcome.METHODS: Seventy-eight pancreatico-enteric anastomosis failure (PEAF) patients of 403 pancreaticoduodenectomy (PD) were included for this retrospective study. PEAF was defined by the presence of rich amylase (over 10,000 IU/L) in drainage fluid at postoperative day 5 to 7 and radiographic demonstration of the anastomotic breakdown and associated local fluid collection. The management was analyzed by observation group (O group), intervention (I group) and surgery group (S group).RESULTS: Preoperative clinical status of the PEAF group and non-PEAF group was similar. Bile duct cancer was the highest risk subgroup of the PEAF (P=0.001) and the pancreatic adenocarcinoma showed the least risk for the PEAF (P<0.001). Among the 78 PEAF patients, 50 were managed as a conservative treatment, 15 patients were received radiologic intervention and 13 patients performed rescue surgery. Among these three subgroups, there was no statistical significance in the patient's demographics, clinical status, surgical factors and disease nature. However, mortality was significantly higher in the S group (P<0.001). The mortality cases were developed one and six patients in O and S group, respectively. Surgical procedures in S group were completion total pancreatectomy with or without splenectomy (n=12) and pancreatectomy preserving spleen in four (28.6%). Pancreaticogastrostomy repair and Roux-en-Y pancreaticojejunostomy reconstruction were performed each case, respectively.CONCLUSION: Proper drainage catheter indwelling during the PD or postoperative radiological intervention can effectively manage the PEAF without surgical interventional treatment.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness of computed tomography (CT) Hounsfield unit histogram analysis (HUHA) in postoperative pancreatic fistula (PF) prediction. MATERIALS AND METHODS: Fifty-four patients (33 males and 21 females; mean age, 65.6 years; age range, 37–89 years) who had undergone preoperative CT and pancreaticoduodenectomy were included in this retrospective study. Two radiologists measured mean CT Hounsfield unit (CTHU) values by drawing regions of interest (ROIs) at the level of the pancreaticojejunostomy site on preoperative pre-contrast images. The HUHA values were arbitrarily divided into three categories, comprising HUHA-A ≤ 0 HU, 0 HU < HUHA-B < 30 HU, and HUHA-C ≥ 30 HU. Each HUHA value within the ROI was calculated as a percentage of the entire area using commercial 3-dimensional analysis software. Pancreas texture was evaluated as soft or hard by manual palpation. RESULTS: Fifteen patients (27.8%) had clinically relevant PFs. The PF group had significantly higher HUHA-A (p < 0.01) and significantly lower mean CTHU (p < 0.01) values than those of the non-PF group. The HUHA-A value had a moderately strong correlation with PF occurrence (r = 0.60, p < 0.01), whereas the mean CTHU had a weak negative correlation with PF occurrence (r = −0.27, p < 0.01). The HUHA-A and mean CTHU areas under the curve (AUCs) for predicting PF occurrence were 0.86 and 0.65, respectively, with significant difference (p < 0.01). The HUHA-A and mean CTHU AUCs for predicting pancreatic softness were 0.86 and 0.64, respectively, with significant difference (p < 0.01). CONCLUSION: The HUHA-A values on preoperative pre-contrast CT images demonstrate a strong correlation with PF occurrence.

ABSTRACT

Pancreaticopleural fistula (PPF) a fistulous connection between the pancreas and pleural space due to prolonged chronic pancreatitis (CP). PPF is a very rare complication which presents in 0.4% of chronic pancreatitis cases, especially among children. We report a case involving a 3-year-old boy who presented with pleural effusion caused by a PPF, a complication of hereditary pancreatitis, which was, for the first time in Korea, successfully managed with endoscopic treatment. Chest radiography and computed tomography showed massive pleural effusion. Percutaneous catheter drainage was performed. High amylase levels were observed in the pleural fluid and serum, suggesting PPF. The patient was managed with bowel rest and octreotide infusion. Endoscopic retrograde cholangiopancreatography revealed CP, and pleural effusion was successfully managed with stent placement. PRSS1 genetic screening revealed R122H mutation.

ABSTRACT

ABSTRACT BACKGROUND: Pancreatic fistula represents the most feared complication after pancreatoduodenectomies, being the major responsible for the high morbidity and mortality after this operation. Its incidence remains around 10% to 30%. In recent years, several authors have studied the value of amylase in abdominal drains fluid, measured at an early stage after the surgical procedure, as a useful tool to identify patients at risk of developing pancreatic fistula. OBJECTIVE: To analyze the value of early drain fluid amylase as a method to predict the occurrence and severity of postoperative pancreatic fistula in patients undergoing pancreatoduodenectomies. METHODS: We evaluated 102 prospective patients submitted to pancreatoduodenectomies from January 2013 to June 2017. The mensuration of amylase in abdominal drains was performed on days 1, 3, 5 and 7 in all patients. Patients were divided into three groups according to postoperative day 1 (POD1) results: values <270 U/L (group 1); between 271 and 5.000 U/L (group 2); and values >5.000 U/L (group 3). RESULTS: The incidence of pancreatic fistula was 25.5%, being 3.33%, 27.3% and 41.02% in the three groups, respectively. Compared with group 1, the risk of developing pancreatic fistula increased with increasing amylase values on POD1. Amylase values on POD1 and POD3 of patients with pancreatic fistula were higher than in the other ones without this complication (P<0.001). In addition, in group 3, 37.5% of patients with pancreatic fistula evolved to death (P<0.001). Finally, in this group, patients who died had drain fluid amylase values on POD1 significantly higher than the others in the same group (P<0.001). CONCLUSION: Early drain fluid amylase value is a useful test to stratify patients in relation to the risk of developing pancreatic fistula after pancreatoduodenectomies, in addition to correlate with the severity of this complication.


RESUMO CONTEXTO: A fístula pancreática representa a complicação mais temida após as duodenopancreatectomias, sendo a grande responsável pela elevada morbi-mortalidade após esta operação. Sua incidência permanece em torno de 10% a 30%. Nos últimos anos, diversos trabalhos têm estudado o valor da amilase nos drenos abdominais, medido de forma precoce após o procedimento cirúrgico, como ferramenta útil para a identificação dos pacientes sob risco de desenvolver fístula pancreática. OBJETIVO: Avaliar o valor da amilase no fluido dos drenos abdominais, obtido precocemente no pós-operatório, como método para prever a ocorrência e severidade da fístula pancreática nos pacientes submetidos a duodenopancreatectomias. MÉTODOS: Foram avaliados 102 pacientes prospectivos submetidos a duodenopancreatectomias no período de janeiro de 2013 a junho de 2017. A dosagem da amilase nos drenos abdominais foi realizada nos dias 1, 3, 5 e 7 em todos os pacientes. Os pacientes foram divididos em três grupos conforme os resultados do 1o PO: valores <270 U/L (grupo 1); entre 271 e 5.000 U/L (grupo 2); e valores >5.000 U/L (grupo 3). RESULTADOS: A incidência de fístula pancreática foi de 25,5%, sendo 3,33%, 27,3% e 41,02% nos três grupos, respectivamente. Comparados ao grupo 1, o risco de desenvolver fístula pancreática foi crescente com o aumento da amilase no 1o PO. Os valores das amilases no 1o PO e 3o PO dos pacientes com fístula pancreática foram maiores do que nos pacientes sem essa complicação (P<0,001). Além disso, no grupo 3, 37,5% dos pacientes com fístula pancreática evoluíram para óbito (P<0,001). Por fim, neste grupo, os pacientes que evoluíram para óbito tiveram valores de amilase no 1o PO significativamente maiores do que os demais pacientes (P<0,001). CONCLUSÃO: O valor da amilase, medido de forma precoce nos drenos abdominais no pós-operatório de duodenopancreatectomias, é teste útil para estratificar pacientes em relação ao risco de apresentar fístula pancreática, além de se correlacionar com a severidade dessa complicação.

ABSTRACT

ICG is widely applied in real-time imaging during abdominal surgery, plastic surgery, as well as oncologic staging and treatment. A twenty-eight year-old female patient was found to have a 4.5 cm solid pseudopapillary neoplasm in the tail of the pancreas. Under ICG-fluorescent pancreatic perfusion-guidance, we easily defined the margin of the pancreatic tumor and secured the resection margin when performing laparoscopic distal pancreatosplenectomy in the patient. No clinically relevant complications, including postoperative pancreatic fistula, were noted. Intravenous ICG can be very easily and quickly detected in the pancreas under near infrared light. This enhanced vision gives strong contrast to the organ compared to a necrotic tumor with poor blood perfusion, such as solid pseudopapillary neoplasm. Based on our current experience, ICG pancreatic perfusion-guided determination of appropriate resection margin is useful and feasible during pancreaticoduodenectomy.

ABSTRACT

PURPOSE: A soft texture of the pancreas is one of the most important predisposing factors for a pancreatic fistula. Thus, in a porcine model, we investigated a method to harden the pancreas locally by directly injecting an artificial material. METHODS: During the laparotomy, 51 samples from 17 pigs, including 13 survival models, were randomly divided into 3 groups and either received a direct injection into the pancreas of MHL (1:4 mixture of histoacryl [n-butyl cyanoacrylate] and lipiodol) (group E) or saline (group C) or only received a pinprick into the pancreas without injecting a substance (sham). We measured the change in the pancreatic hardness after the injection using a durometer and examined the histological change of the pancreas using the fibrosis grade in the survival model. RESULTS: The postinjection hardness of the pancreas was significantly increased in group E compared to group C and the sham group (P < 0.001). Pathologically, all cases in group E showed a severe fibrotic change, whereas the other groups demonstrated mild to no fibrosis (P < 0.001). The fibrosis in group E was localized to the area of the injection, while the surrounding areas were preserved. CONCLUSION: The direct injection of MHL could induce focal hardening and fibrotic changes in the pancreas of the porcine model.

ABSTRACT

PURPOSE: Leakage of pancreatico-jejunal anastomosis (PJ) remains the primary cause of morbidity and mortality after Whipple's operation. To reduce the occurrence thereof, the present author recently began to apply a modification of the Blumgart method of anastomosis after Whipple's operation (hereinafter referred to as Lee's method), with very good results. MATERIALS AND METHODS: The modified method and technique utilizes fish-mouth closure of a beveled pancreatic stump and parachuting of the pancreatic end with double U trans-pancreatic sutures (symmetric horizontal mattress-type sutures between the full thickness of the pancreas and the jejunal limb) after duct-to-mucosa pancreatico-jejunostomy. RESULTS: Eleven cases of pylorus preserving Whipple's operation have been performed without a clinically significant postoperative pancreatic fistula. CONCLUSION: This new method (Lee's method) may dramatically reduce the occurrence of postoperative pancreatic fistula after Whipple's operation.
