Surgical endoscopy
-
Laparoscopic sleeve gastrectomy (LSG) is gaining popularity as an additional bariatric procedure, either as a first step for biliopancreatic diversion or gastric bypass or as a stand-alone option for selected patients. Early postoperative fluid tolerance varies between patients and influences the length of hospital stay. Swallow studies after LSG are not uniform and display different patterns with regard to contrast passage through the gastric sleeve. ⋯ Tolerance of fluid intake after LSG is crucial for patient recovery and discharge. A distinct radiologic appearance on postoperative day 1 helps to predict this behavior. The different patterns could be related to gastric sleeve construction or to possible postoperative sleeve spasm, hindering fluid passage. The influence of immediate fluid tolerance on weight loss after LSG is currently under investigation.
