Abstract
BACKGROUND: The primary aim of this study was to examine the motor activity (motility) of a gastric tube after laparoscopic-assisted proximal gastrectomy (LPG). A secondary objective was to ascertain whether a correlation exists between gastric tube motor activity and reflux esophagitis. PATIENTS AND METHODS: A total of 41 patients who underwent LPG for early gastric cancer were studied. The motility of the gastric tube and the status of reflux esophagitis were evaluated. Manometric recording was performed 2 weeks and 1 year after surgery. RESULTS: In a fasting state, the motilities of the distal gastric tube and duodenum recovered within 1 year after surgery but that of the proximal gastric tube did not recover. Improvement of the motility of the gastric tube was associated with a decreased number of patients with reflux esophagitis 1 year after surgery. In patients with reflux esophagitis, the motility of the distal gastric tube was significantly lower than that in patients without reflux esophagitis. CONCLUSION: After LPG, the motility of the gastric tube recovered, and the incidence of reflux esophagitis decreased with time, in parallel to recovery of gastrointestinal motility. Copyright
