Obesity and appendicitis: Laparoscopy versus open technique

Objectives: The clinical results of obese patients who have undergone open or laparoscopic appendectomy, whether one technique is superior to the other is still not clearly known.In our study, we compared the clinical results of obese patients operated with laparoscopic or open technique for acute appendicitis.

Material and methods: We performed retrospective analyses of patients operated for acute appendicitis between the dates of July 2016 and July 2019 at Istinye University Faculty of Medicine Bahcesehir Liv Training and Research Hospital and Liv Hospital Ankara. Of the 241 patients whose height and weight information was accessible, 57 had a body mass index of 30 kg/m2 or higher. Eighteen of these patients underwent open surgery while the other 39 underwent laparoscopic surgery. The primary result criterion was complication ratio. Secondary criteria were operation time and length of hospital stay.

Results: Upon comparison of laparoscopic and open techniques in terms of intraoperative-postoperative complications (p= 0.01), operation time (p= 0.02) statistically significant differences were found between the groups. However the mean length of hospital stay (p= 0.181) was similar in both groups.

Conclusion: In obese appendicitis patients, the laparoscopic technique proved to be superior to the open technique in criteria such as perioperative-postoperative complications, operation time, and etc. Length of hospital stay was determined to be similar between the groups.
