Abstract

Background: Leakage from the staple line is the most serious complication encountered after sleeve gastrectomy, occurring in 2.4% of surgeries. The use of inappropriately sized staplers, because of variability in stomach wall thickness, is a major cause of leakage. Objectives: To measure stomach wall thickness across different stomach zones in order to identify variables correlating with thickness. Methods: The study comprised 100 patients (52 females). Stomach wall thickness was measured immediately after surgery using a digital caliper at the antrum, body, and fundus. Results were correlated with body mass index (BMI), age, gender, and pre-surgical diagnosis of diabetes, hypertension, hyperlipidemia and fatty liver. Results: Stomach wall thickness was found to be 5.1 ± 0.6 mm at the antrum, 4.1 ± 0.6 mm at the body, and 2.6 ± 0.5 mm at the fundus. No correlation was found between stomach wall thickness and BMI, gender, or co-morbidities. Conclusions: Stomach wall thickness increases gradually from the fundus toward the antrum. Application of the correct staple height during sleeve gastrectomy is important and may, theoretically, prevent leaks. Staplers should be chosen according to the thickness of the tissue.
