Intraoperative esophageal manometry employed in the course of Heller's cardia-myotomies / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the changes of lower esophageal sphincter (LES) high-pressure zone, and to determine the accurate length of myotomy on the esophageal and gastric sides.</p><p><b>METHODS</b>There were 15 patients undergoing the Heller's cardia-myotomies and Toupet fundoplications from May 2006 to December 2007. Among them, 9 patients were female and 6 was male. The age ranged from 28 to 61 years old, and the disease duration ranged from 6 months to 9 years. The intraoperative oesophageal manometry underwent in the surgical procedures to investigate the changes of the lower esophageal sphincter pressure and the length of myotomy.</p><p><b>RESULTS</b>There was no postoperative death. After (5.3 +/- 1.5) cm of esophageal side myotomy and (0.8 +/- 0.4) cm of gastric side myotomy, the mean LES pressure decreased from (33.6 +/- 13.3) mm Hg (1 mm Hg = 0.133 kPa) to (9.7 +/- 4.6) mm Hg and (4.8 +/- 3.1) mm Hg respectively (P < 0.05). The lower esophageal sphincter length ranged from 5 to 8 cm.</p><p><b>CONCLUSION</b>Intraoperative esophageal manometry helps determine the accurate myotomy length of myotomy on the esophageal and gastric sides of the gastroesophageal junction and provides valuable information for the Heller's myotomy.</p>
