Abstract:

Introduction: The prevalence of obesity is increasing all over the world. Laparoscopic sleeve gastrectomy (LSG) has become the most common bariatric surgery in the world today. Unlike other bariatric surgeries, laparoscopic sleeve gastrectomy yields a pathological examination. The aim of this study was to describe unexpected histopathological findings following LSG. Methods: In this study, the pathologies of 1364 patients who underwent LSG between March 2013 and September 2019 were analyzed retrospectively. Patients were evaluated by a multidisciplinary team in the preoperative period. Patients who met the criteria for LSG were operated. These criteria were; Body Mass index (BMI) ≥40 kg/m2 or BMI >35 kg/m2 and comorbidities or BMI between 30 and 35 kg/m2 with accompanying Type 2 diabetes Mellitus or Metabolic syndrome. Two hundred four of the patients underwent gastroscopy preoperatively. Results: One thousand three hundred sixty four patients underwent LSG. The mean age was 40.93±10.86 years; 974 patients (71.48%) were female. The mean BMI was 42.23±7.28. The most common findings in the pathologies were normal gastric specimen (50%), gastritis (30%) and changes due to proton pump inhibitor use (23%) respectively. Conclusion: Gastroscopy should be added to the preoperative preparation process in cases where there is no gastric specimen after the operation. Preoperative gastroscopy is not a necessity for laparoscopic sleeve gastrectomy. It can be performed in selected cases.
