Abstract
BACKGROUND: Intragastric surgery with a single incision has been performed for several diseases, such as gastric tumors[1] and pancreatic pseudocyst[2], safety, feasibility and potential benefits of which have been reported in previous relevant studies[3]. METHODS: The video shows a 65-year-old man with upper gastrointestinal hemorrhage, preoperative abdominal CT scan and endoscopy suggested an endophytic tumor located in gastric corpus, suggesting gastrointestinal stromal tumor (GIST). Intragastric single-port surgery (IGS) was indicated. RESULTS: Under general anesthesia, patient was placed in supine position. Surgeons stood on the right side of the patient. After a 2.5cm transverse incision was made on left upper abdominal wall, gastric anterior wall was exteriorized and fixed to the skin incision. Single-port device was inserted inside the stomach after anterior gastric wall was opened. Next, laparoscope was introduced into gastric cavity and identified the location of tumor. Full thickness resection of the tumor was performed by using linear stapler, then stapler line was embedded with continuous sutures. Finally, after specimen and single-port device removal, the stomach incision was closed extracorporeally. The operation time was 112 minutes. Final pathology confirmed GIST (4.5cm) with negative margins and patient discharged after 4 days, without postoperative complications. In 1-year follow-up time, without recurrence or death. CONCLUSION: IGS is safe and effective for gastric endophytic GIST resection, which not only preserves all advantages of conventional laparoscopic operation, but also includes other benefits like obviating the need of abdominal cavity exploration, potential reduction of risk of neoplasm seeding, and offering good postoperative cosmetic result.
