Laparoscopic diverticulectomy or laparoscopic-assisted resection of symptomatic Meckel diverticulum in children? A systematic review.

Recent reports have recommended laparoscopic diverticulectomy for symptomatic Meckel diverticulum (MD) rather than laparoscopic-assisted extracorporeal resection. This technique may risk leaving residual ectopic mucosa leading to complications. This systematic review attempts to quantify the relative risks of both approaches. A systematic review was conducted according to PRISMA guidelines. Articles were eligible for inclusion if they reported data on the laparoscopic management of symptomatic MD in children. Eleven reports were identified, all of which were institutional retrospective studies. Pooled outcome data on 248 children showed no statistically significant difference in complications between laparoscopic diverticulectomy (n = 133) and laparoscopic-assisted segmental resection (n = 115) (3% vs. 6.1%, p = 0.39). One patient from the diverticulectomy group re-presented with recurrent bleeding necessitating segmental small bowel resection. Conclusions are limited by the number of patients and variable follow up. Short, wide MD with a height:base ratio of < 2; diverticula with thickening or ischemia at the base and those complicated by volvulus or small bowel obstruction are probably best treated by laparoscopic-assisted extracorporeal resection. For other symptomatic diverticula laparoscopic diverticulectomy is a reasonable approach with a less than 1% risk of leaving residual ectopic gastric mucosa.
