Laproscopic versus open appendectomy: a comparative study

Abstract

Objective: To compare the results of open with laparoscopic appendectomy in terms of postoperative pain, rate of wound infection and hospital stay.

Methods: This quasi-experimental study was conducted in Deprtment of Surgery, Ziauddin University Hospital, Karachi, over a period of six months. Patients undergoing surgery for acute appendicitis were randomly assigned into one of the two groups (A or B) after obtaining written and informed consent. In Group-A patients underwent open appendectomy and in Group B laparoscopic appendectomy was performed. Post operatively pain chart and wound infection was recorded and, at the time of discharge, number of days in hospital was calculated.

Result: Sixty patients (38 male, 22 female), with clinical diagnosis of acute appendicitis based on Alvarado score of six and above, were included in the study. They were randomized into 2 groups of A and B with 30 patients in each group. Group-A comprised open appendectomy procedure and Group-B comprised laparoscopic appendectomy. Mean comparison of postoperative pain by visual analogue scale, was significantly low in Group B, compared with Group A, on day 0, 1 and 2. Number of days in Hospital was 4.1 +/- 0.8 days in Group A and 1.5 +/- 0.06 days in Group B. None of the patients in Group B, while 8 (26.67%) patients in-Group A, developed postoperative wound infection at 1 week follow up.

Conclusion: Laparoscopic appendectomy is safe and effective. Wound infection and postoperative pain is significantly lower after this mode of surgery
