BACKGROUND: Our aim was to determine the optimum appendectomy technique in patients with morbid obesity by evaluating laparoscopic appendectomy (LA) and open appendectomy (OA) operations performed in these patients.
MATERIAL AND METHODS: The records of 2179 patients who underwent appendectomy for acute appendicitis between January 2010 and April 2019 were evaluated retrospectively. Patients were excluded for the following: age <18 years; body mass index (BMI) of <40 kg/m²; perforation and/or plastron detected. The remaining 89 patients were included in the study. The patients were divided into 2 groups: the LA group (n=40) and the OA group (n=49). Demographic data, duration of operation, operation-related wound infection status, operation-related intra-abdominal complication status, operation-related nonsurgical complication status, and length of hospital stay were recorded.
RESULTS: No statistically significant difference was found between the 2 groups in terms of age and sex (P=0.062, P=0.078, respectively). However, the average BMI value in the LA group was significantly higher than that of the OA group (P<0.001). Duration of operation and length of hospital stay were significantly lower in the LA group than in the OA group (P<0.001, P<0.001, respectively). General complications and wound infection were significantly lower in the LA group than in the OA group (P=0.012, P=0.031, respectively).
CONCLUSIONS: Although LA did not have a clear advantage over OA in patients with morbid obesity, it should be emphasized that laparoscopic surgery may be preferred due to advantages such as a shorter length of hospital stay and lower risk of wound infection.
