Outcome and quality of life in obese patients underwent laparoscopic vs. open appendectomy

Although obesity is a popular reason for choosing laparoscopic appendectomy (LA) versus open appendectomy (OA), however, the question of whether there is a difference remains. Our goal is to investigate if there is a difference between OA and LA in obese patients.

Fifty-eight obese patients diagnosed with acute appendicitis according to ALVARDO score at department of surgery at Suez Canal university hospitals from March 2020 till August 2021 were included. The study participants were assigned in two groups LA and OA. This study aimed to comparing between LA and OA regarding intraoperative complications, length of hospital stays, post -operative pain, and rate of post-operative complications. Meanwhile, using SF-36 scoring questionnaire, the quality of life was compared between both groups.

A total of 58 patients were included in the present study (LG = 29 patients and OG = 29 patients). The early post-operative complications (within 30 days after surgery) were significantly lower in the LA group (5 patients out of 29) than the OA (11 patients out of 29). Additionally, lower incidence of complications was noticed in the LA group (2 out of 29 patients) compared to OA (6 patients out of 29) beyond 30 days after operation. Patients with laparoscopic surgery had statistically significant higher overall quality of life scores (SF-36) (72 ± 32) compared to open surgery patients (66 ± 35) 2 weeks after operation.

The laparoscopic procedure was associated with lower incidence of post operative complications. However, open appendectomy was superior for a shorter operative time. Laparoscopic approach is not only used for therapeutic purposes, but also it has a diagnostic role.
