A gastrointestinal stromal tumor at the esophagogastric junction successfully treated by laparoscopic wedge resection with seromuscular layer dissection: a case report

摘要

Herein, we report a case of a gastrointestinal stromal tumor (GIST) at the esophagogastric junction (EGJ) that was successfully treated by a laparoscopic wedge resection (LWR) after dissection of the seromuscular layer around the tumor to prevent postoperative deformities and stenosis of the EGJ. Subsequently, the abdominal esophagus was wrapped by the gastric fornix according to Dor’s method in order to prevent reflux esophagitis after surgery. A 71-year-old female patient was admitted with a diagnosis of a GIST (23?×?20?×?20?mm) at the EGJ. We performed the abovementioned operation. Gastroduodenal endoscopic examination revealed no deformity or stenosis of the EGJ at 6?months after the operation. The patient has not experienced any reflux symptoms. Tumor recurrence was not noted 26?months after the operation. This procedure is useful in preventing the deformity and stenosis of the EGJ as well as postoperative reflux esophagitis
