Intragastric pressure and peristalsis analysis of the sleeve gastric tube after laparoscopic sleeve gastrectomy

Introduction

Laparoscopic sleeve gastrectomy (LSG) is a procedure that is being increasingly recommended. However, LSG can worsen gastroesophageal reflux disease (GERD) and cause vomiting, and consequently impact the quality of life (QOL) of patients. Abnormal motility of the sleeve gastric tube has been linked to the onset of GERD and vomiting. Hence, this study investigated the peristalsis of the sleeve gastric tube after LSG and its relationship with gastroesophageal reflux. There are only a few reports on the peristalsis of the sleeve gastric tube after LSG.

Methods

We measured the motility function of the sleeve gastric tube using high-resolution manometry (HRM) within 2–4 weeks after LSG. The manometry catheter was positioned in the antrum using fluoroscopy.

Results

This analysis included 18 patients. Postoperative HRM measurement of the sleeve gastric tube was characterized by the absence of gastric body peristalsis in at least 90% of swallows and contractions of the antrum. Furthermore, reverse peristalsis was observed from the pyloric antrum toward the stomach body although the frequency was low.

Conclusions

LSG was associated with characteristic of pressure and peristalsis in sleeve gastric tube. HRM was able to detect and visualize intragastric pressure and peristalsis of the sleeve gastric tube.
