Abstract
Background and objectives: The opportunity of evaluating histological changes has increased since laparoscopic sleeve gastrectomy (LSG) has been a common surgical treatment for morbid obesity in recent years. This research was designed to describe gastric specimens that has been surgically resected.
The study was conducted retrospectively based on records from a single center in the UAE.
Results: Of 585 patients, 205 were men (35%) and 380 were women (65%). The average body mass index was 43.8 kg/m2. The average age at the time of the operation was 29.93 years. 202 patients (34.5%), had histopathologic findings in the resected specimens. The main histopathologic findings were normal stomach mucosa (383, or 65.5%) and chronic gastritis was the second most common diagnosis, with 182 cases (31.2%), followed by H pylori positivity in 11 samples (1.3%) and Dysplasia-intestinal metaplasia was found in 5 patients (0.9%) of the patients. Out of those with chronic gastritis it was found that 51 (28%) cases had positive H pylori test earlier.
Conclusions: All sleeve gastrectomy specimens should be histologically examined, as the results revealed curable problems where endoscopies prior to sleeve gastrectomy may have missed some lesions, histopathologic investigations are crucial for accurate diagnosis.
Several variables, including age, gender, the histology of the stomach that was removed, and the presence or absence of H. pylori, should be taken into account when attempting to predict the success of weight loss following surgery.
