Abstract
Background
Laparoscopic resection of gastric stromal tumors is being performed with increased frequency. This study aims to evaluate the feasibility and safety of the extraluminal laparoscopic gastric wedge resection (ELWR) technique.
Methods
Clinical data of 84 patients who underwent ELWR for gastric submucosal tumors between September 2000 and December 2007 were reviewed and analyzed retrospectively. The operation includes: localization of the tumor, dissection of the omentum, mobilization of the upper stomach and the upper pole of the spleen, exposure of esophago-cardiac junction (ECJ), and wedge resection of the upper part of gastric body and/or the gastric fundus with endoscopic gastrointestinal anastomosis (Endo GIA) stapler.
Results
All of the procedures were performed successfully, with mean operation time of 62.6 ± 8.9 min and mean intraoperative blood loss of 86.2 ± 8.1 ml. Through extraluminal laparoscopic wedge resection, complete R0 resection was achieved for all tumors. All surgical margins were negative microscopically. No lesions were missed, nor were there any significant postoperative complications or intraoperative conversions to open surgery. A total of 78.6% of the patients recovered their gastrointestinal functions and began to eat and ambulate within 36 h of the operation. The smallest surgical margins were 0.7–2.5 cm, with a mean distance of 1.4 ± 0.5 cm. Of the 84 cases of gastric submucosal tumors, 29 cases were leiomyomas, 51 cases were various types of stromal tumors, and 4 other cases were neurofibromas. Mean follow-up duration was 51 ± 4.3 months (overall follow-up rate 73.8%, 62/84 cases), during which no recurrences or metastases were found.
Conclusion
ELWR is a safe, simple, and effective procedure for treating submucosal tumors in the upper part of the stomach. It can avoid intraperitoneal contamination, possible tumor spillage, and postoperative esophageal stenosis, and provides unlimited scope for gastric resection.
