title: Evaluation of laparoscopic appendectomy vs. open appendectomy: a retrospective study at Aga Khan University Hospital, Karachi, Pakistan.
abstract: OBJECTIVE
  To compare open and laparoscopic appendectomies and to evaluate the level of efficacy of both types of appendectomy performed at Aga Khan University Hospital (AKUH).
  
  
  METHODS
  Based on this strong study rationale, a clinical audit of patient's records was performed to evaluate the significance of this technique as a treatment modality. The study population comprised of patients with appendicitis admitted in the Department of Surgery from January 2004 to December 2004. The patients' charts were reviewed to ascertain whether the procedure was done as an acute case or as an elective procedure. The predictor variables explored in this study were: age, gender, ultrasound and CT focused procedure, operative time, post-operative stay, number of hours required for the return of bowel function, use of narcotic analgesia and the total hospital bill of the respective patients.
  
  
  RESULTS
  A total of 49 patients' clinical charts were reviewed. Of these, 29 patients had had laparoscopic appendectomies and the remaining 20 had open appendectomies. The mean post-operative stay in days was relatively shorter for laparoscopic appendectomy (1.97 +/- 2.3) compared to open appendectomy (3.1 +/- 1.8). The average time for the return of bowel movement was remarkably lesser for laparoscopic appendectomy (10.6 +/- 8.2) hours than open appendectomy (21 +/- 13) hours. Two of the independent variables: CT focused (P-value: 0.01) and operative times in minutes (P-value: 0.06) were found to be significantly associated with the types of appendectomy. Hence our study found that laparoscopic appendectomy, although relatively expensive, is a safe and effective procedure for the removal of appendix over open appendectomy.
