Evaluation of the result of single-incision laparoscopic surgery for gastrointestinal stromal tumors in the stomach

Abstract

BackgroundSingle-incision laparoscopic surgery (SILS) has recently been used for the management of gastrointestinal stromal tumors (GIST). Here, the feasibility and effectiveness of SILS for GIST and indications for SILS according to tumor location were investigated.Case presentationFrom July 2009 to May to 2013, a total of 14 patients underwent SILS for GIST. In 14 patients, 5 patients had tumor near the esophagogastric junction, 4 patients on the lesser curvature, 2 patients on the anterior wall, 2 patients on the posterior wall, and 1 patient on the greater curvature. The surgery of one patient with lesser curvature tumor was converted to conventional laparoscopic surgery because of technical difficulties. Another patient required re-operation because of a posterior wall tumor causing gastric obstruction. There was no complication in patients with tumors on the anterior wall and greater curvature.ConclusionsBecause SILS for GISTs located mainly on the anterior wall was feasible, SILS may be considered the most appropriate type of laparoscopic surgery for GISTs in this location. However, for GISTs on the posterior wall or with lesser curvature, which require more complex management, SILS is challenging and should be carefully adapted.
