Abstract

Background

With 80 % of its population overweight, 47.5 % obese, and having the eighth fattest population worldwide, Kuwait has a serious obesity problem. This has led to widespread practice of bariatric surgery, with little or no studies regarding operative findings and patient follow-up. This study aims to identify the prevalent gastric histopathologies of the patients who have undergone laparoscopic sleeve gastrectomy (LSG) at Amiri Hospital, Kuwait.

Methods

A retrospective study was done of the gastric pathology specimen results of 656 patients who underwent LSG at Amiri Hospital from 2008 to 2012.

Results

Of the 656 patients, the average age was 33 years, and 480 (73.2 %) were female while 176 (26.8 %) were male. The histopathology results identified 488 (74.4 %) cases with chronic gastritis, 63 (9.6 %) with follicular gastritis, and 12 (1.8 %) with atrophic gastritis. A total of 12 (1.8 %) cases showed findings other than gastritis, including four (0.6 %) cases of gastric polyps, three (0.5 %) cases of granulomatous disease, and one (0.2 %) case each of the following: gastro-intestinal stromal tumor, gastro-intestinal autonomic nerve tumor, intestinal metaplasia, collagenous gastritis, and crypt cell apoptosis. Helicobacter pylori was discovered in 48 (7.3 %) of the patients.

Conclusions

The majority of gastric histopathology results after LSG in this study had an element of chronic gastritis (74.4 %), which is in keeping with previous studies showing its high prevalence among the obese population. However, a few cases had clinically significant pathologies, and this may alter post-operative management. In view of these results, routine histological examination of the gastric specimens is highly recommended.
