Description
Background Laparoscopic sleeve gastrectomy (LSG) is now considered an effective bariatric procedure (American Society for Metabolic and Bariatric Surgery statement). We attempted to assess the size of the gastric fundus remaining after LSG and gastric voiding rate (fast/slow) by radiological upper gastrointestinal series (UGS) with a water-soluble contrast medium (CM). The findings were compared with weight loss data. Methods Seventy-four obese patients underwent LSG. Radiological UGS were used to measure the remaining fundus size in 28 of 74 patients 24–72 h after the procedure, with the aid of Matlab software and a library image processing toolbox (MathWorks®). Sleeve voiding was measured in 57 of 74 patients, based on the patients’ radiological reports. Results The mean volume of the remaining fundus was 17.56 ml (range 1.00–77.03 ml). The mean percent excess BMI loss (%EBL) was 39.5%, 53.7%, and 60.8%, respectively, 3, 6, and 12 months after LSG. Sleeve voiding was fast in 49 of 57 patients (85.96%) and slow in eight (14.03%). Conclusions No correlation was found between the estimated volume of the remaining gastric fundus and weight loss (%EBL) after LSG. Patients showing a rapid gastroduodenal transit of the CM achieved a better weight loss than patients with a slow voiding rate.
