Optimal timing of elective laparoscopic cholecystectomy after acute cholangitis and subsequent clearance of choledocholithiasis

BACKGROUND: Elective laparoscopic cholecystectomy is recommended after endoscopic clearance of choledocholithiasis for patients with acute cholangitis, according to Toyko guidelines. However, the optimal timing remains uncertain. METHODS: Perioperative outcomes were retrospectively reviewed and compared between patients with early (< 6 weeks) and late (> 6 weeks) surgeries, while risk factors for postoperative complications were assessed using multivariate analysis. RESULTS: One hundred twelve patients (mean age, 64 years; range, 30-85 years) were analyzed. Rate of conversion and intraoperative and postoperative complications (classified per Dindo et al) were 21.4% (24 of 112), 23.2% (26 of 112), and 34.8% (39 of 112), respectively. The late surgery group had significantly more intraoperative (28.8% vs 9.4%, P = .029) and postoperative (42.5% vs 15.6%, P = .007) complications compared with the early surgery group. Multivariate analysis showed both late surgery (95% confidence interval, 1.47-12.5; P = .008) and a history of endoscopic sphincterotomy (95% confidence interval, 1.06-8.26; P = .038) to be independent risk factors for postoperative complications. CONCLUSIONS: Patients with endoscopic clearance of choledocholithiasis, especially after endoscopic sphincterotomy, should receive elective laparoscopic cholecystectomy within 6 weeks after a cholangitic attack.
