Histopathological findings in laparoscopic sleeve gastrectomy specimens.

To study the demographic data and histopathological specimen findings of patients who have undergone laparoscopic sleeve gastrectomy. A retrospective descriptive study. Pathology and Laboratory Medicine Department, Al-Ahli Hospital, Doha, Qatar. Data of patients who underwent laparoscopic sleeve gastrectomy between January 1, 2009 and December 31, 2016 were retrospectively collected from the laboratory information system of Al-Ahli Hospital. A total of 342 patients underwent laparoscopic sleeve gastrectomy. Among these patients, 294 (86%) were Qatari and 241 (70%) were female. The patient age ranged from 13 to 72 years, and most patients were in the 31-40-year age group. Histological examination of specimens showed that lymphocytic aggregates in the lamina propria were the most frequent histopathological finding (171, 50%), followed by no remarkable pathological finding (98, 28.6%). The other pathological findings were follicular gastritis, fundic gland polyps, and acute and chronic gastritis. Our findings clearly indicate the need for routinely performing histopathological examination of laparoscopic sleeve gastrectomy specimens. The study also highlights lymphocytic aggregates as the most common histopathological finding.
