Endoscopic management of cystic stump leaks: Insights from a tertiary care center

Abstract

Background: Cystic stump leakage is the most common cause of bile leakage following cholecystectomy, representing a significant postoperative complication that requires prompt intervention. Currently, endoscopic treatment is the preferred management approach. This study aims to identify factors influencing the success of endoscopic therapy for cystic stump leaks by analyzing cases treated at our institution.

Methods: Thirty-seven patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) for cystic stump leakage were included in this study. Patient demographics, associated complications, and length of hospital stay were analyzed.

Results: All patients showed clinical improvement, with a mean hospital stay of 5.1 days. The presence of comorbidities, emergency surgery, or conversion to open surgery did not significantly impact treatment efficacy. Post-procedure, percutaneous drainage was required in 10 patients (27%). Procedure-related pancreatitis was noted in one patient (2.7%). Statistical analysis revealed that both the need for percutaneous drainage and the length of hospital stay were significantly lower in patients who had pre-existing drains (p<0.03). Additionally, early ERCP was associated with a significantly shorter hospital stay (p<0.01).

Conclusion: Stent placement via ERCP is a safe and effective strategy for managing cystic stump leaks. Early ERCP intervention following cystic stump leak detection is recommended. Furthermore, percutaneous drainage may be necessary in patients who do not respond adequately to initial treatment.
