Study of laparoscopic appendectomy: advantages, disadvantages and reasons for conversion of laparoscopic to open appendectomy

Abstract

Background:Good outcome has been reported with the laparoscopic approach in uncomplicated appendicitis, but a higher incidence of postoperative intraabdominal abscesses has been reported after laparoscopic appendectomy in complicated appendicitis. Objective was to study the efficacy of laparoscopic appendectomy.Methods: A Hospital based cross sectional study was carried out among of 302 patients. The study duration was from June 2004 to December 2006. Institutional Ethics Committee permission was obtained. Informed individual consent was taken. Out of 302 subjects, 236 underwent open appendectomy and 66 underwent laparoscopic appendectomy.Results:It was observed that in both the groups majority patients had retrocecal position of the appendix. The amount of blood loss, adjacent organ injury and duration of surgery were similar in both the groups. The difference in the incidence of wound infection in both groups was not found to be statistically significant. But the antibiotic use was significantly less in the LA group compared to OA group. It was found that time to resumptions of oral fees, duration of hospital stay and time to return to normal duties were significantly lesser in LA group compared to OA group. (p < 0.001). As per the cosmetic end result, majorities were satisfied in LA group and rated the surgery as excellent as compared to patients in OA group.Conclusions:Laparoscopic appendectomy was better than open appendectomy with respect to wound infection, tackling co-existing pathology, duration of hospital stay, earlier return to normal activity, excellent cosmetic end result, lesser use of antibiotics and earlier resumption of oral feeds.
