Background: The reported advantages of the laparoscopic approach to appendectomy are shortened hospital stay, less postoperative pain, and earlier return to usual activities (work). However, a prospective, randomized, double-blind trial comparing laparoscopic appendectomy with open appendectomy in active-duty males failed to disclose a benefit of laparoscopic appendectomy with regards to postoperative pain and return to work. The aim of our study was to compare open and laparoscopic appendectomy in overweight patients. Methods: We conducted a prospective, randomized, double-blind study to determine whether laparoscopic appendectomy or the open procedure in overweight patients offers a significant reduction in lost workdays, postoperative pain, or operative time from. Open appendectomy in overweight patients (those with a body mass index ≥25) may be more difficult due to excessive sub-cutaneous adipose tissue. The open incision may be of considerable size, which may result in increased postoperative pain and a prolonged convalescence. Results: There was a statistically significant increase in operative time for laparoscopic appendectomy of 11 minutes. As expected, the aggregate incision length for open appendectomy was twice that of the laparoscopic appendectomy. Conclusion: The data from this prospective, randomized, double-blind study failed to demonstrate any significant reduction in lost workdays, postoperative pain, or operative time with laparoscopic appendectomy.
