Abdominal Wound Metastasis after Laparoscopic Surgery of Gastrointestinal Stromal Tumor

Abstract

Surgical resection is the mainstay treatment for gastrointestinal stromal tumors (GISTs). Laparoscopic surgery can be considered for treating these tumors since their biologic behavior lends them to curative resection without requiring large margins or extensive lymphadenectomy. Despite complete resection, GISTs frequently recur specifically in the liver and peritoneum. Although they occur in other upper gastrointestinal malignancies, recurrences of GISTs at the port sites after laparoscopic surgery have rarely been reported. We describe here a patient with abdominal wound metastasis after laparoscopic surgery for GIST.

Bloc biopsy by using submucosal endoscopy with a mucosal flap method for gastric subepithelial tumor tissue sampling (with video)

“…To prevent tumor seeding, 22 this method uses the long attachment method for tissue collection, clip closure from the tumor side, and simultaneous resection of tunneling during hybrid NOTES. Histologically, none of the 3 GI stromal tumor cases that underwent hybrid NOTES exhibited tumor seeding within the short tunnels.…”

Endoscopic submucosal dissection for treatment of gastric subepithelial tumors (with video)

“…[25][26][27][28][29] However, abdominal wound metastasis may be a rare complication of this method. 30 Currently, ESD is widely used in Japan and Korea to remove superficial neoplastic lesions from the GI tract. Its efficacy and safety have been confirmed in large series of patients with gastric cancer or adenoma.…”

Predictors of Recurrence After Resection of Small Gastric Gastrointestinal Stromal Tumors of 5 cm or Less

“…16 Laparoscopic resection may be suggested as a reasonably feasible procedure for patients with low-risk smaller gastric GISTs of 5 cm or less despite the risks for positive resection margin and port site recurrence. [17][18][19][20][21][22][23] Moreover, several small case series have studied endoscopic resection of GIST. 24 One of the major concerns of endoscopic resection is an inability to obtain sufficient resection margin.…”
