Abstract Background Postoperative pancreatic fistula formation (POPF) remains one of the most common and detrimental complications following pancreaticojejunostomy (PJ). The aim of this meta-analysis is to analyze the efficacy of external pancreatic duct stent placement in preventing POPF formation following PJ. Methods The primary end-point was the incidence of POPF formation following pancreaticoduodenectomy (PD) in the presence and absence of external stent placement. Secondary outcomes examined were the incidence of perioperative mortality, delayed gastric emptying, postoperative wound infection, operative time, blood loss, and length of hospital stay. Results Four trials were included comprising 416 patients. External pancreatic duct stenting was found to reduce the incidence of both any grade POPF formation (OR 0.37, 95% CI = 0.23 to 0.58, p  = 0.0001) and clinically significant (grade B or C) POPF formation (OR 0.50, 95% CI = 0.30 to 0.84, p  = 0.0009) following PD. The use of an external stent was also found to significantly lessen length of hospital stay (SMD −0.39, 95% CI = −0.63 to −0.15, p  = 0.001). Conclusions This analysis has shown that external pancreatic duct stenting is indeed efficacious in the incidence of both any grade as well as clinically significant POPF formation following PD. Length of hospital stay was also found to be significantly less by external duct stenting.

Background: Postoperative pancreatic fistula (POPF) remains one of the most common causes of morbidity following pancreaticoduodenectomy (PD). This randomized trial examined whether external stent drainage of the pancreatic duct decreases the rate of POPF after PD and subsequent pancreaticojejunostomy (PJ). Methods: Consecutive patients who underwent PD with subsequent construction of a duct-to-mucosa PJ were randomized into a stented and a non-stented group. The primary outcome was the incidenc...

Objective: Pancreatic fistula (PF) is a leading cause of morbidity and mortality after pancreaticoduodenectomy (PD). The aim of this multicenter prospective randomized trial was to compare the results of PD with an external drainage stent versus no stent. Methods: Between 2006 and 2009, 158 patients who underwent PD were randomized intraoperatively to either receive an external stent inserted across the anastomosis to drain the pancreatic duct (n = 77) or no stent (n = 81). The criteria of inclu...

Objectives: We prospectively investigated the efficacy of an external pancreatic duct stent to prevent pancreatic fistula in the nonfibrotic pancreas after pancreaticojejunostomy, in which the degree of pancreatic fibrosis was assessed objectively by using dynamic magnetic resonance imaging (MRI). Methods: Among the 67 consecutive patients who underwent pancreatic head resection, 45 patients were judged to have a normal pancreas without fibrosis based on the preoperative assessment of pancreatic...

Abstract Background A stent often is placed across the pancreaticojejunostomy. However, there is no report compared between internal drainage and external drainage. Methods We conducted a prospective randomized trial ( NCT00628186 registered at http://ClinicalTrials.gov ) with 100 patients who underwent pancreaticoduodenectomy and we compared the effects on postoperative course.

The role of endoscopic therapy in the management of pancreatic diseases is continuously evolving; at present most pathological conditions of the pancreas are successfully treated by endoscopic retrograde cholangio-pancreatography (ERCP) or endoscopic ultrasound (EUS), or both. Endoscopic placement of stents has played and still plays a major role in the treatment of chronic pancreatitis, pseudocysts, pancreas divisum, main pancreatic duct injuries, pancreatic fistulae, complications of acute pan...

Pancreaticoduodenectomy is the treatment of choice for patients with resectable carcinoma of the pancreatic head and periampullary region. In recent years, mortality rate of pancreaticoduodenectomy has declined to <5% in many institutions around the world.1–4 However, pancreatic fistula still occurs in 5% to 40% of patients after pancreaticoduodenectomy, depending on the definition of leakage.5–8 The reduction in operative mortality over the past few decades has not been accompanied by a notable...

IntroductionCurrently pancreaticoduodenectomy (PD) is thetreatment of choice for tumours of the periampullaryregion. PD is a complex, high-risk surgical procedure,considered to be one of the most binding operations or, maybe, the most binding in abdominal surgery[1 4].In 1979 Moossa defined PD as ‘the Cadillac ofabdominal surgery’ [5]. In the same period thein-hospital mortality rate after PD was 20 30% withan extremely high morbidity; severe, life-threateningcomplications were judged to be a pa...

Pancreatic duct stenting remains an attractive strategy to reduce the incidence of pancreatic fistulas following pancreaticoduodenectomy (PD) with encouraging results in both retrospective and prospective studies. We performed a prospective randomized trial to test the hypothesis that internal pancreatic duct stenting reduces the development of pancreatic fistulas following PD. Two hundred thirty-eight patients were randomized to either receive a pancreatic stent (S) or no stent (NS), and strati...

Pancreatic cancer is one of the dreaded malignancies for both the patient and the clinician. The five-year survival rate of pancreatic adenocarcinoma (PDA) is as low as 2% despite multimodality treatment even in the best hands. As per the Global Cancer Observatory of the International Agency for Research in Cancer estimates of pancreatic cancer, by 2040, a 61.7% increase is expected in the total number of cases globally. With the widespread availability of next-generation sequencing, the entire ...

Background Pancreatic fistulas remain a significant concern after pancreatectomy owing to the associated high risk of mortality and high costs. It is not possible to perform preoperative risk stratification for all patients. This study aimed to evaluate the usefulness of the measurement of portal vein (PV) distance as a predictive indicator of pancreatic fistula development after pancreatoduodenectomy and compare it with the usefulness of other indicators such as body mass index (BMI), and abdom...

Postoperative pancreatic fistulas are complex, challenging problems that often take weeks, months, or longer to resolve. Multiple interventions may be required to achieve a successful outcome. As such, resolution typically involves a multidisciplinary approach by a team whose skills include abdominal imaging, specialized surgery, advanced endoscopy, and interventional radiology. Intensive resources and time are often required, which impacts both patients and their caregivers. While treatment(s) ...

Abstract Background Several studies comparing internal and external stents have been conducted with the aim of reducing pancreatic fistula after PD. There is still no consensus, however, on the appropriate use of pancreatic stents for prevention of pancreatic fistula. This multicenter large cohort study aims to evaluate whether internal or external pancreatic stents are more effective in reduction of clinically relevant pancreatic fistula after pancreaticoduodenectomy (PD). Methods We reviewed 3...

: Postoperative pancreatic fistula (POPF) is one of the most severe complications after pancreatic surgeries. POPF develops as a consequence of pancreatic juice leakage from a surgically exfoliated surface and/or anastomotic stump, which sometimes cause intraperitoneal abscesses and subsequent lethal hemorrhage. In recent years, various surgical and perioperative attempts have been examined to reduce the incidence of POPF. We reviewed several well-designed studies addressing POPF-related factors...
