Surgical Treatment for Choledocholithiasis Following Repeated Failed Endoscopic Retrograde Cholangiopancreatography.

ABSTRACT

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is the first line treatment for choledocholithiasis. In many occasions, several attempts of ERCP are performed until failure is declared and surgical treatment is applied, in many times following procedure-related complications. We present the results of surgical management of patients with choledocholithiasis following repeated failures of ERCP due to impaction of multiple large stones. METHODS: Patients that underwent surgical treatment for choledocholithiasis following repeated ERCP attempts between January 2006 and December 2018 were retrospectively assessed. Post-ERCP complications were evaluated and the surgical approach, technique, and outcomes were assessed. RESULTS: One hundred and two patients were operated on for choledocholithiasis following repeated failed ERCP. All the patients had at least 2 failed attempts (mean = 3.2 ± 1.7), and 25 (23.5%) suffered major ERCP-related complications. Following choledochotomy and stone extraction, bilioenteric anastomosis was done in the vast majority of patients (90.2%), most commonly choledochoduodenostomy (62%). Thirty-eight (37%) patients had minimally invasive procedure (laparoscopic n = 26, robotic assisted n = 12). Major post-operative complications (Clavien-Dindo ≥ 3) occurred in 24 patients (23.5%). Nine patients (8.8%) were re-operated and 10 (9.8%) were readmitted within 30 days from surgery. Three patients died within 30 days from surgery. Older patients had significantly more ERCP attempts and suffered higher post-operative mortality. During a median follow-up of 70 months, the only biliary complication was an anastomotic stricture in one patient. CONCLUSION: Surgery for CBDS after failure of ERCP is safe and provides a highly effective long-term solution.
