A Cochrane review 1[Abstract] included 7 studies. A total of 488 participants with acute cholecystitis and fit to undergo laparoscopic cholecystectomy were randomised to early laparoscopic cholecystectomy (ELC) (244 people) and delayed laparoscopic cholecystectomy (DLC) (244 people) in the six trials.
There was no mortality in any of the participants in five trials that reported mortality. There was no significant difference in the proportion of people who developed bile duct injury in the two groups (ELC 1/219 (adjusted proportion 0.4%) versus DLC 2/219 (0.9%); Peto OR 0.49; 95% CI 0.05 to 4.72 (5 trials)). There was no significant difference between the two groups (ELC 14/219 (adjusted proportion 6.5%) versus DLC 11/219 (5.0%); RR 1.29; 95% CI 0.61 to 2.72 (5 trials)) in terms of other serious complications. There was no significant difference between the two groups in the proportion of people who required conversion to open cholecystectomy (ELC 49/244 (adjusted proportion 19.7%) versus DLC 54/244 (22.1%); RR 0.89; 95% CI 0.63 to 1.25 (6 trials)).
The total hospital stay was shorter in the early group than the delayed group by four days (MD -4.12 days; 95% CI -5.22 to -3.03 (4 trials; 373 people)). There was no significant difference in the operating time between the two groups (MD -1.22 minutes; 95% CI -3.07 to 0.64 (6 trials; 488 people)). The people belonging to the ELC group returned to work earlier than the DLC group (MD -11.00 days; 95% CI -19.61 to -2.39 (1 trial; 36 people)). Forty (18.3%) of the people belonging to the delayed group had either non-resolution of symptoms or recurrence of symptoms before their planned operation and had to undergo emergency laparoscopic cholecystectomy in five trials. The proportion with conversion to open cholecystectomy was 45% (18/40) in this group of people.
