Evaluation of Digital Radiography on Gastric Motility After Laparoscopic Assisted Gastrectomy

摘要

This article focuses on the assessment of remnant gastric motility after laparoscopic assisted pylorus preserving gastrectomy compared with laparoscopic assisted distal gastrectomy. Thirty-six patients underwent laparoscopic assisted distal gastrectomy without preservation of the pylorus (LADG) for tumors located in the lower third of the stomach, while 36 patients underwent laparoscopic assisted pylorus preserving gastrectomy (LAPPG) for tumors in the middle third of the stomach. We assessed postoperative gastric emptying and motility using dynamic X-ray imaging. LAPPG has advantages over LADG in terms of gastric emptying time (57+-31 % for LADG and 45+-21 % for LAPPG) and remnant gastric motility (2.29+-2.30% for LADG and 139+2.65% for LAPPG). LAPPG should be used instead of LADG in selected patients with early gastric cancer arising in the middle third of the stomach.
