The tumor in the gastric corpus was resected using a full thickne

The tumor in the gastric corpus was resected using a full thickness resection technique with the Plicator, which has previously been reported by our group. In the other cases, a submucosal tunneling technique was used. All tumors were resected completely. Histology revealed a GIST with

low mitotic activity in case 1, a fibrotic cyst in case 2, a granulosa cell tumor in case 3 and an adenomyoma in case 4. In all cases, histology confirmed complete resection oft the tumor. No serious complications occurred. In case 1 the Plicator endoscopic sewing device was used to place two full-thickness resorbable sutures at the base of the tumor. The tumor was then resected with a snare. The two sutures ensured gastric wall patency during and after endoscopic resection of the tumor. In the other cases, a submucosal tunneling technique as previously described in the POEM procedure was used to gain Crizotinib submucosal access to the tumor. A mucosal incision selleck chemical was created 5-10 cm proximal to the tumor after lifting the mucosa by injection of a tolouidin blue and glycerosterile.

Submucosal tunneling was performed using the TT knife with spray coagulation to dissect submucosal fibres. After identifying the tumor in the submucosal tunnel it was then carefully dissected from the mucosa and extracted with a snare or a forceps. The mucosal incision was closed using standard clips or an OTSC clip. In one case, the tumor could not be separated from the muosa, so the tumor was then resected in ESD-technique. In this case series, different techniques for resection of subepithelial tumors are described. Full thickness suturing before snare resection was discribed previously to be safe and effective for resection of gastric GISTs. Submucosal tunneling and subsequent submucosal tumor resection offers a new and safe way for resection of not only esophageal but also gastric tumors.

Compared to standard ESD techniques it allows very good direct visualisation of the tumor Atorvastatin in the submucosa. In addition, it harbors the advantage of leaving the resection site covered with an intact mucosal layer and thereby minimizing the risk of peritonitis or mediastinitis in case of accidental perforation of the gastric or esophageal wall. Larger case series and clinical studies are needed to further evaluate this method. “
ectomy is a safe and effective approach to thoroughly clear SB polyps when surgery is indicated, and this combined approach of intensive small bowel surveillance may reduce the incidence of future polyp-related morbidity. “
“Although different techniques have been reported, endoscopic resection of subepithelial tumors remains challenging. In this case series we discribe different approaches focusing on a submucosal tunneling technique. Between October and November 2012, 4 patients recieved endoscopic resection of subepithelial tumors in the upper GI tract.
