This was a prospective randomized controlled study designed to compare laparoscopic and open interval appendectomy and involved 100 patients of appendicular phlegmon. After initial conservative management, patients were divided into 2 groups of 50 each and interval appendectomy was performed by laparoscopy in one of the groups and by open method in the other. Mean operative time in open surgery was 33.9 minutes and that in laparoscopic surgery was 57.64 minutes (P < 0.05). Concomitant pathology was observed in 16% and 2% of patients in the laparoscopic and open groups, respectively. Mean pain scores on the first postoperative day were 5.14 in the laparoscopic group and 6.01 in the open group (P < 0.05). Patients in the laparoscopic group had a shorter duration of ileus, postoperative stay, and returned to work earlier (P < 0.05). We conclude that laparoscopy offers a number of advantages over open interval appendectomy.
