Abstract

Background: Gallstone pancreatitis is one of the most common causes of acute pancreatitis. Cholecystectomy remains the definitive treatment of choice to prevent recurrence. The rate of early cholecystectomies during index admission remains low due to perceived increased risk of complications.

Aim: To compare outcomes including length of stay, duration of surgery, biliary complications, conversion to open cholecystectomy, intra-operative, and post-operative complications between patients who undergo cholecystectomy during index admission as compared to those who undergo cholecystectomy thereafter.

Methods: Statistical Method: Pooled proportions were calculated using both Mantel-Haenszel method (fixed effects model) and DerSimonian Laird method (random effects model).

Results: Initial search identified 163 reference articles, of which 45 were selected and reviewed. Eighteen studies (n = 2651) that met the inclusion criteria were included in this analysis. Median age of patients in the late group was 43.8 years while that in the early group was 43.6. Pooled analysis showed late laparoscopic cholecystectomy group was associated with an increased length of stay by 88.96 h (95%CI: 86.31 to 91.62) as compared to early cholecystectomy group. Pooled risk difference for biliary complications was higher by 10.76% (95%CI: 8.51 to 13.01) in the late cholecystectomy group as compared to the early cholecystectomy group. Pooled analysis showed no risk difference in intraoperative complications [risk difference: 0.41%, (95%CI: -1.58 to 0.75)], postoperative complications [risk difference: 0.60%, (95%CI: -2.21 to 1.00)], or conversion to open cholecystectomy [risk difference: 1.42%, (95%CI: -0.35 to 3.21)] between early and late cholecystectomy groups. Pooled analysis showed the duration of surgery to be prolonged by 39.11 min (95%CI: 37.44 to 40.77) in the late cholecystectomy group as compared to the early group.

Conclusion: In patients with mild gallstone pancreatitis early cholecystectomy leads to shorter hospital stay, shorter duration of surgery, while decreasing the risk of biliary complications. Rate of intraoperative, post-operative complications and chances of conversion to open cholecystectomy do not significantly differ whether cholecystectomy was performed early or late.
