ABSTRACT
BACKGROUND/AIMS:
The removal of esophageal and gastric submucosal tumors is difficult using conventional endoscopic mucosal resection methods. This study examined the usefulness of an endoscopic subtumoral dissection for an en-bloc resection of submucosal tumors.METHODS:
An endoscopic subtumoral dissection was attempted for an en-bloc resection in 15 submucosal tumors (M F=10 5, 13 stomach, 2 esophagus). Before the procedures, endoscopic ultrasonography was performed in all cases. The procedure was carried out using various electrosurgical knives, such as an endoscopic submucosal dissection.RESULTS:
Pathological and immunohistochemical studies confirmed a gastrointestinal stromal tumor in 6 cases. Other pathological diagnoses were made in 9 patients with submucosal lesions leiomyoma (4), ectopic pancreas (3), lipoma (1), and hemangioma (1). An en-bloc resection was performed in 13 of the 15 tumors (86.7%). The mean specimen size was 29.5x21.1 mm. The mean procedure time was 49.4 minutes (range 8~103 minutes). Gastric perforation was a complication in 2 cases with GIST. However, the two perforated cases were treated with endoscopic closure using endoclips and recovered without the need for surgery.CONCLUSIONS:
An endoscopic subtumoral dissection technique is useful for an en-bloc resection of esophageal and gastric submucosal tumors. However, sufficient attention should be paid to the detection of perforations in the case of tumors with a proper muscle origin.
