Novel surgical approach for gastric gastrointestinal stromal tumor (GIST): Robotic single port partial gastrectomy

A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed. The histological diagnosis was an intra-abdominal desmoid tumor. A desmoid tumor is a fibrous soft tissue tumor arising in the fascia and musculoaponeurotic tissues. It usually occurs in the extremities and abdominal wall, and only rarely in the abdominal cavity. We experienced a case with an intra-abdominal desmoid tumor that was histologically diagnosed after laparotomy, which had been preoperatively diagnosed as an extragastric growing gastrointestinal stromal tumor. Although rare, desmoid tumors should be considered in the differential diagnosis of intra-abdominal tumors. Herein, we report this case with a literature review.

A 76-year-old man presented to our hospital with abdominal distention and loss of appetite. The 10% of weight lost relative to this patient in 1 month. Abdominal computed tomography and magnetic resonance imaging revealed a giant mass, with a major axis of 23 cm, containing solid components, not involving the upper abdominal organs. Esophagogastroduodenoscopy showed extramural compression from the middle gastric body to the antrum, as well as a normal mucosal surface. These findings were suggestive of a gastrointestinal stromal tumor attached to the anterior wall of the stomach without metastasis or invasion. Partial gastrectomy was performed for tumor resection, and the patient was subsequently treated with adjuvant imatinib. We report a rare case of a large extramural gastrointestinal stromal tumor of the stomach that was larger than 20 cm in diameter and present a pertinent literature review.

Objectives. Duplication cysts are rare benign lesions usually arising in the gastrointestinal tract. We report a case of a 52-year-old woman with an incidental gastric mass found on computed tomography during a pregraft workup for a familial cardiomyopathy.Methods. The mass was completely excised by partial gastrectomy and gross examination revealed a cystic lesion containing two small solid nodules in its wall. Microscopic evaluation and immunohistochemistry study were performed to further characterize the cyst and the nodules. A comprehensive literature review of the NCBI database PubMed was also carried out.Results. While the cyst was diagnosed as a foregut duplication cyst, the solid nodules proved to be concomitant gastrointestinal stromal tumor (GIST) and leiomyoma. Both morphologic features and immunohistochemistry stains, including CD117, smooth muscle actin, and CD34 supported the diagnosis. Clinical course was benign and the patient had no clinical evidence of relapse ten months following the surgical procedure. The literature search did not reveal any other published case of a foregut duplication cyst presenting in combination with a GIST and a leiomyoma.Conclusions. To our knowledge, this is the first case of a composite lesion comprising a foregut duplication cyst of the stomach along with a leiomyoma and a GIST.

Vessel Sealing

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.
