Abstract Background: Few studies investigated biliary leakage after pancreaticoduodenectomy (PD) especially when compared to postoperative pancreatic fistula (POPF). This study was to determine the incidence of biliary leakage after PD, predisposing factors of biliary leakage, and its management.
Methods: We retrospectively studied all patients who underwent PD from January 2008 to December 2017 at Gastrointestinal Surgery Center, Mansoura University, Egypt. According to occurrence of postoper- ative biliary leakage, patients were divided into two groups. Group (1) included patients who developed biliary leakage and group (2) included patients without identified biliary leakage. The preoperative data, operative details, and postoperative morbidity and mortality were analyzed.
Results: The study included 555 patients. Forty-four patients (7.9%) developed biliary leakage. Ten patients (1.8%) had concomitant POPF. Multivariate analysis identified obesity and time needed for hepaticojejunostomy reconstruction as independent risk factors of biliary leakage, and no history of preoperative endoscopic retrograde cholangiopancreatiography (ERCP) as protective factor. Biliary leakage from hepaticojejunostomy after PD leads to a significant increase in development of delayed gastric emptying, and wound infection. The median hospital stay and time to resume oral intake were significantly greater in the biliary leakage group. Non-surgical management was needed in 40 patients (90.9%). Only 4 patients (9.1%) required re-exploration due to biliary peritonitis and associated POPF. The mortality rate in the biliary leakage group was significantly higher than that of the non-biliary leakage group (6.8% vs 3.9%, P = 0.05).
Conclusions: Obesity and time needed for hepaticojejunostomy reconstruction are independent risk factors of biliary leakage, and no history of preoperative ERCP is protective factor. Biliary leakage increases the risk of morbidity and mortality especially if concomitant with POPF. However, biliary leakage can be conservatively managed in majority of cases.
