Abstract

Laparoscopic surgery is widely accepted for uncomplicated Crohn's disease (CD) because it offers faster recovery, less pain, and better cosmesis. In complex CD with fistulas or abscesses, however, dense adhesions and fragile tissue make surgery technically demanding and increase postoperative morbidity. Most previous studies comparing laparoscopic and open surgery were limited by selection bias and lacked multivariate adjustment. Robust evidence on the safety of laparoscopy and predictors of postoperative complications remains scarce.
