The Relationship Between Histopathologic Findings and Weight Loss in Laparoscopic Sleeve Gastrectomy

Aim The aim of this study was to investigate the correlation between histopathologic findings detected in laparoscopic sleeve gastrectomy (LSG) specimens and excess weight loss percentages (%EWL) and excess BMI decrease percentages (%EBL). Methods Patients who underwent LSG in the hospital's Gastroenterological Surgery Department between the years 2013 and 2018 and who completed 1 year of follow-up were involved in the study. Patients whose 6th month and 12th month BMI were unknown were excluded from the study. Clinical and pathologic data of the cases were obtained from the automation system of the hospital. Results As a result of comparison among diagnosis groups, it was detected in the histopathologic analysis that the 12th month mean %EWL measurement was higher in the inactive stomach diagnosis group. In the comparisons among intestinal metaplasia (IM) groups, it was seen that 6th month %EWL and %EBL and 12th month %EWL and %EBL measurements were higher in the group without IM. Age, baseline BMI and active gastritis incidence in histopathologic analysis have a negative effect on weight loss. Conclusions A correlation of histopathologic changes in morbid obese patients with weight loss after bariatric surgery was asserted in this study. Operating on younger patients with lower BMI and inactive gastritis with the LSG method could contribute to achieving more successful results. Prospective research studies are necessary within this context.
