Efficacy and safety of endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy and biliary stenting in post-operative bile leaks.

Abstract

We evaluated the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP), sphincterotomy, balloon biliary tract scanning, and plastic stenting in diagnosing and treating bile duct leakage after laparoscopic cholecystectomy and hydatid cyst surgery in this study. The study evaluated patients who underwent ERCP, sphincterotomy, and stenting for post-operative bile leakage. The patients were grouped under 4 groups (cystic duct stump, sac bed, hydatid cyst, and choledochal) according to the bile leakage de-tected in the ERCP procedure. The success of the procedure after the ERCP was evaluated by drain extraction time, whether early complications such as bleeding, pancreatitis, and perforation developed due to the ERCP procedure and the presence of obstructive pathology in ERCP. Clinical improvement was observed in 65/73 (89%) patients who underwent successful ERCP procedures, and their drains could be removed. The mean drain removal time was 32.69±23.32 days. After laparoscopic cholecystectomy, bile leakage was most frequently from the cystic duct stump. There was no difference between the groups in procedural success rates. Drain removal time was shorter in the patient group with leakage from the cystic duct compared to the other three groups (P<0.05). After the ERCP procedure, 5/73 (6.9%) patients had minor ERCP complications, which improved with medical treatment. No major ERCP complication was observed. In addition, 25/73 patients (34.2%) had obstructive pathology such as biliary stone and hydatid membrane. In patients with biliary leak due to laparoscopic cholecystectomy and hydatid cyst surgery, ERCP, sphincterotomy, balloon scanning, and plastic stenting are both highly effective and reliable options. They should be considered as the first-choice treat-ment approach in this patient group.
