Background
The timing of laparoscopic cholecystectomy (LC) performed after the mild acute biliary pancreatitis (MABP) is still controversial. We conducted a review to compare same-admission laparoscopic cholecystectomy (SA-LC) and delayed laparoscopic cholecystectomy (DLC) after mild acute biliary pancreatitis (MABP).
Methods
We systematically searched several databases (PubMed, EMBASE, Web of Science, and the Cochrane Library) for relevant trials published from 1 January 1992 to 1 June 2018. Human prospective or retrospective studies that compared SA-LC and DLC after MABP were included. The measured outcomes were the rate of conversion to open cholecystectomy (COC), rate of postoperative complications, rate of biliary-related complications, operative time (OT), and length of stay (LOS). The meta-analysis was performed using Review Manager 5.3 software (The Cochrane Collaboration, Oxford, United Kingdom).
Results
This meta-analysis involved 1833 patients from 4 randomized controlled trials and 7 retrospective studies. No significant differences were found in the rate of COC (risk ratio [RR] = 1.24; 95% confidence interval [CI], 0.78–1.97; p = 0.36), rate of postoperative complications (RR = 1.06; 95% CI, 0.67–1.69; p = 0.80), rate of biliary-related complications (RR = 1.28; 95% CI, 0.42–3.86; p = 0.66), or OT (RR = 1.57; 95% CI, − 1.58–4.72; p = 0.33) between the SA-LC and DLC groups. The LOS was significantly longer in the DLC group (RR = − 2.08; 95% CI, − 3.17 to − 0.99; p = 0.0002). Unexpectedly, the subgroup analysis showed no significant difference in LOS according to the Atlanta classification (RR = − 0.40; 95% CI, − 0.80–0.01; p = 0.05). The gallstone-related complications during the waiting time in the DLC group included gall colic, recurrent pancreatitis, acute cholecystitis, jaundice, and acute cholangitis (total, 25.39%).
Conclusion
This study confirms the safety of SA-LC, which could shorten the LOS. However, the study findings have a number of important implications for future practice.
