Results: Of 199 randomized patients, 101 were assigned to undergo laparoscopic peritoneal lavage and 98 were assigned to colon resection. At the time of surgery, perforated purulent diverticulitis was confirmed in 145 patients randomized to lavage (n = 74) and resection (n = 71). The median follow-up was 59 (interquartile range, 51-78; full range, 0-110) months, and 3 patients were lost to follow-up, leaving a final analysis of 73 patients who had had laparoscopic lavage (mean [SD] age, 66.4 [13] years; 39 men [53%]) and 69 who had received a resection (mean [SD] age, 63.5 [14] years; 36 men [52%]). Severe complications occurred in 36% (n = 26) in the laparoscopic lavage group and 35% (n = 24) in the resection group (P = .92). Overall mortality was 32% (n = 23) in the laparoscopic lavage group and 25% (n = 17) in the resection group (P = .36). The stoma prevalence was 8% (n = 4) in the laparoscopic lavage group vs 33% (n = 17; P = .002) in the resection group among patients who remained alive, and secondary operations, including stoma reversal, were performed in 36% (n = 26) vs 35% (n = 24; P = .92), respectively. Recurrence of diverticulitis was higher following laparoscopic lavage (21% [n = 15] vs 4% [n = 3]; P = .004). In the laparoscopic lavage group, 30% (n = 21) underwent a sigmoid resection. There were no significant differences in the EuroQoL-5D questionnaire or Cleveland Global Quality of Life scores between the groups.

Conclusions and relevance: Long-term follow-up showed no differences in severe complications. Recurrence of diverticulitis after laparoscopic lavage was more common, often leading to sigmoid resection. This must be weighed against the lower stoma prevalence in this group. Shared decision-making considering both short-term and long-term consequences is encouraged.
