Background: The optimal endoscopic procedure and the appropriate duration of treatment in management of patients with biliary leaks after laparoscopic cholecystectomy (LC) have not been established so far. The aim of the study is the evaluation of endoscopic drainage by endoscopic sphincterotomy (ES) and/or nasobiliary tube placement in treatment of biliary leaks after LC.
Material And Methods: ERCP identified a biliary fistula site after LC in 17 patients as arising from the cystic duct stump (n = 12), anomalous branch of right hepatic duct (n = 1) and common bile duct (n = 4). The mean time from LC to referral was 7.5 days. Therapy consisted of insertion of 7F-nasobiliary tube without ES in 13 patients and with ES in 4 patients. ES was performed only in cases of common bile duct injury. Nasobiliary tubes were used in all patients because this allowed for frequent contrast examinations in order to monitor efficacy of therapy and to determine the exact duration of treatment required.
Results: Nasobiliary tube placement alone was effective for the treatment of biliary leaks after LC in all patients, except 4 patients with common bile duct injury. Nasobiliary tube alone is not as effective for drainage of this part of the biliary tree as the combination of ES with nasobiliary tube. All leaks closed within 1 week, except for four patients with common duct leaks in whom 2 weeks were required for closure of the fistula.
Conclusion: Nasobiliary tube placement is effective in healing biliary leaks after LC. I prefer to avoid ES because of its procedure-related risk. ES was performed only in cases of common bile duct injury in order to reduce the resistance to normal bile to a minimum.

Background: Pancreatic enucleation is indicated for selected patients and tumours with very low oncological risk to preserve a maximum of healthy pancreatic parenchyma. Minimally invasive pancreatic enucleation (MIPE) is increasingly performed. This study aims to assess the impact of tumor location and center experience on textbook outcomes (TBO) in patients undergoing MIPE.

Introduction: Choledocholithiasis is a common clinical condition that may present with severe complications such as acute cholecystitis or cholangitis, requiring treatment on an emergency setting. This situation is frequently managed following an endoscopic approach by ERCP. However, access to emergent endoscopic biliary decompression is lacking in most centers.

Post-surgical biliary complications increase morbidity, mortality, and healthcare utilization. Early detection and management of biliary complications is thus of great clinical importance. Even though the overall risk for biliary complications is low after laparoscopic cholecystectomy, post-cholecystectomy biliary complications are frequently encountered in clinical practice as laparoscopic cholecystectomy is the most common surgical procedure performed in the United States.

Background: Biliary leakage is a serious complication of hepato-pancreato-biliary operations, increasing morbidity and mortality, and challenging clinicians.
Objective: This study aims to evaluate the incidence of bilioenteric anastomotic leakage, treatment options, and their outcomes at a high-volume tertiary referral center.
Methods: A retrospective cohort study was conducted to analyze the outcomes of patients who underwent biliary anastomosis formation between 2016 and 2021.

Background: This study is a retrospective review aimed to identify pancreatic juice-specific fluorescent probes to visualize pancreatic juice using a library of 381 aminopeptidase/protease-activatable fluorescent probes and 30 phosphatase/phosphodiesterase probes. In 2013, we developed a fluorescence imaging technique using a chymotrypsin probe to visualize pancreatic juice, linked to postoperative pancreatic fistula (POPF). This probe required addition of trypsin to convert pancreatic chymotrypsinogen to chymotrypsin.
