Abstract

Background: Laparoscopic sleeve gastrectomy (LSG) is an accepted bariatric procedure. Swallow studies (SS) after LSG are not uniform and display different patterns with regard to contrast passage through the gastric sleeve. The impact of immediate postoperative contrast transit time on weight loss has not been studied. The influence of immediate fluid tolerance on weight loss after LSG is herein reported. Methods: Ninety-nine patients after LSG were included. There were 67 females, mean age 41 (range 17-67), mean BMI 44.4 (range 37-75). A routine SS was performed on postoperative day (POD) 1. Pattern of contrast transit was noted. Patients were followed-up in our bariatric clinic. Results: Percent excess weight loss was significantly lower in the patients with rapid contrast passage (Group 1, n = 50) than those with delayed passage (Group 2, n = 49). Group 1 achieved 62, 58, and 53 % at 1, 2, and 3 years, respectively, while Group 2 attained 69, 74, and 75 % at the same time points (p = 0.05, 0.001, and 0.04, respectively). Group 1 patients displayed a negative weight loss trend after 1 year whereas Group 2 patients plateaued after 2 years. Conclusions: Tolerance of fluid intake after LSG is crucial for patient recovery and discharge. Distinct radiologic appearance on POD 1 helps predict this behavior. Mid-term weight loss after LSG appears to be dependent on immediate postoperative contrast transit time, whereas patients with slow contrast passage tend to lose more weight. Long-term follow-up will reveal whether this finding will hold true.
