Laparoscopic appendectomy does not change the incidence of postoperative infectious complications

Abstract

Background: It is not clear whether the laparoscopic approach does decrease the incidence of postoperative infectious complications after appendectomy.

Methods: One hundred sixty-nine patients were randomized, 87 with laparoscopic (LA) and 82 with open appendectomy (OA). Patients in the OA group had a McBurney incision; LA was performed in the lithotomy position.

Results: Acute appendicitis was confirmed in 75% of patients. The appendix was perforated in 5 patients of the LA versus 2 patients of the OA group. No conversion to the open procedure was necessary. The median operating time was 35 minutes in the LA group and 31 minutes in the open group (P = 0.58). The median postoperative hospital stay was shorter after laparoscopic than after open surgery (3 days versus 4 days, P = 0.026), whereas the time required for return to work was not significantly different (14 versus 15 days). There were 5 (6%) patients with superficial wound infection following LA and 6 (7%) after OA (P = 0.67). Intra-abdominal fluid collections were found in 2 (2%) patients following LA and 3 (4%) patients following OA (P = 0.60). In the LA group, 3 patients presented with intra-abdominal hemorrhage and another 3 developed a paralytic ileus that was treated conservatively.

Conclusions: Laparoscopic appendectomy is as safe and as effective as the open procedure; however, it does not decrease the rate of postoperative infectious complications.
