Only one trial including 84 patients compared treatment with antibiotics to that with no antibiotics; there was no significant difference between the two groups in terms of length of hospital stay and morbidity. Some 5830 patients with ACC were included, of whom 2997 had early cholecystectomy, 2791 received initial antibiotic treatment, and 42 were treated conservatively. Risk of bias was high in most studies, and all but three studies had a low level of evidence. For randomized studies, pooled event rates were 15 (95 per cent c.i. 10 to 22) per cent for the need for emergency intervention and 10 (5 to 20) per cent for recurrence of ACC.
