“…[26] We have higher incidence of GIST, more than 1%, in this study than that published in literature [8,21], and occurring in higher age groups. However, the tumor was completely resected and the postoperative period was well but we should deal with caution with these higher age groups.…”

Background: Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric operation in Egypt. To the best of our experience there is no published data in Egypt regarding the results of Histopathological examination of the resected gastric specimen after LSG. Objective: To find the range of gastric pathologies in the resected specimens and trying to answer the question whether the resected specimen after LSG should be sent for Histopathological examination or not? Methods: Data were collected prospectively from the period from February 2014 till May 2017 and included 211 patients. LSG was performed by the bariatric team of our department using the same technique. The resected specimen was sent to the pathology department of our institute for pathological examination. Results: the mean age of the studied patients was 36 ± 11.8 years with mean BMI of 44.1 ± 4.7 Kg/m 2 , and female patients represents 67.8% of the studied patients. Chronic nonspecific gastritis was the most common Histopathological finding and was present in 52.1% of patients, normal histopathology was present in 25.6% of patients, and Helicobacter Pylori (HP) related gastritis was present in19.9 % of patients, gastrointestinal stromal tumor (GIST) was present in 4 (1.9%) cases, and we have 1 case of healed cicatrized ulcer. Conclusion: Benign lesions accounts for 98.1% of the studied patients signifying the non-importance of routine pathological examination of the resected specimen after LSG and should only be done in case of grossly suspected lesions. Preoperative esophagogastroduodenoscopy (EGD) may be advised before surgery.

“…Yuval et al [21] detect 5 cases of GIST among 827 patients, Almazeedi et al [8] has only 1 case of GIST among 656 patients, and a study by Enver Vardar et al [22] found that GIST has an incidence of 1.1 % (in 2 out of 181 patients). On the contrary GIST was not present in many other studies.…”

“…Computed tomography and magnetic resonance imaging are crucial to localize the tumor and investigate potential metastases. In a study performed by Yuval et al, GIST incidence was found to be 0.6% based on retrospective histopathological examinations of gastric specimens resected from obese patients who had undergone LSG (7). Studies have demonstrated the importance of carefully examining the complete stomach with respect to pathological lesions before resection during the LSG procedures.…”

“…There were significant differences in the prevalence of histopathologically detected NE cell hyperplasia in LSG specimens and the prevalence ratio was from 0% up to 39.4% (12)(13)(14)(21)(22)(23)(24)(25). In Gündoğan et al's study, they found this high ratio for the presence of NE cell hyperplasia in LSG specimens.…”

“…Yuval et al presented a large series (827 cases) and they found in only 5 (0.6%) GIST histopathologically in patients with sleeve gastrectomy (21). In addition, in Almazeedi et al study, GIST were found incidentally in one of the 656 patients, and in Gordezky et al study, two GIST cases were detected incidentally in 343 patients (12).…”

Introduction:The presence of increased ratio of obesity caused a rapid increase of bariatric surgery practice. In this study, our purpose is to clarify the histopathologic findings of the patients who have experienced this type of bariatric surgery and to learn more about the distinguishable features of laparoscopic sleeve gastrectomy (LSG) specimens and to contribute to the related literature. Methods: A retrospective study was designed with the histopathologic findings from pathology specimens of 109 patients who experienced LSG between April 2014 and May 2016. To essential data, we used the database system of our institution that contains all of the selected patients for our study. Results: Overall, the average age was collect 36.2 years, and 85 were female while 24 were male. The principal histopathologic features were active chronic gastritis in 9, chronic gastritis in 68, atrophy in 5, and intestinal metaplasia in 8 patients. In two patients, gastrointestinal stromal tumor was found and in another patient, neuroendocrine cell hyperplasia was found. In addition to the dominant histopathologic features including chronic and active chronic gastritis, a small percent of patients had clinically significant pathologic findings in the sleeve gastrectomy specimens and this may have an effect on postoperative management and morbidity. Conclusion: Considering these results, having histopathologic examination of the sleeve gastrectomy specimens as a standard procedure is strongly recommended.
