 Laparoscopic sleeve gastrectomy(LSG)can cause vomiting and aggravation of gastroesophageal reflux disease(GERD), consequently affecting the quality of life(QOL) of patients. We measured the intragastric motilities of the sleeve gastric tube using high-resolution manometry(HRM) which detects and visualizes intragastric pressure and peristalsis of the sleeve gastric tube. In this investigation, the absence of gastric body peristalsis was found after LSG. Furthermore, reverse peristalsis whose frequency was low, was observed from the pyloric antrum toward the stomach body. Hence, it is important to fix the sleeve gastric tube toward lower right in LSG because the difference between esophagogastric junction and antrum in height can prevent gastroesophageal reflux.
