The Single Incision Laparoscopic Intragastric Wedge Resection of Gastric Submucosal Tumor

Since 2010, we have used single-incision laparoscopic surgery (SILS) for patients with a gastric submucosal tumor, as a less invasive alternative to conventional laparoscopy. From September 2010 to January 2011, five patients underwent a local resection for a gastric submucosal tumor using a SILS™ port at Keio University Hospital. We performed partial gastrectomy via the SILS™ port using a 5 mm flexible endoscope, a vessel sealing system, and a stapling device. There were no major intraoperative complications, conversion to laparotomy, or cases of tumor rapture. The average operative time was 89 (range, 72–129) minutes with minimal blood loss. Pathological examination revealed four cases of gastrointestinal stromal tumor and one case of inflammatory fibrosis caused by nonspecific inflammation. Although we examined only a small number of cases in this study, the results suggested that SILS gastrectomy can be performed safely and effectively for gastrointestinal stromal tumor.

Abstract Isolated colonic schwannomas are rare gastrointestinal mesenchymal tumors. Only a small number of cases have been reported. Occurrence of these tumors is more common in the stomach than in the large intestine. These spindle cell lesions are distinct from leiomyoma, leiomyosarcoma, and gastrointestinal stromal tumors because the tumor cells have a distinct immunophenotype, with strong diffuse positivity for S-100 and vimentin, as well as corroborative negative staining of CD117 and smooth muscle markers. We present a case of colonic schwannoma in a 70-year-old woman who had no specific symptoms. The patient was diagnosed with a submucosal tumor in the ascending colon on colonoscopy and abdominal computed tomography. Laparoscopic-assisted wedge resection of colon was performed. The very rare pathologic diagnosis of ascending schwannoma was made postoperatively. This case is interesting because schwannomas of the colon and rectum are extremely rare and are treated by laparoscopic-assisted wedge resection.
