Robotic-assisted laparoscopic wedge resection of a gastric leiomyoma with intraoperative ultrasound localization

摘要

Gastric leiomyoma is a rare gastric neoplasm that traditionally has been resected for negative margins using an open approach. The laparoscopic approach may also treat various gastric tumors without opening the gastric cavity. Robotic surgery was developed in response to the limitations and drawbacks of laparoscopic surgery. Herein, we describe a case of robotic-assisted laparoscopic wedge resection of a gastric leiomyoma. A 63-year-old male complaining of abdominal pain was found to have an incidental 3 cm antral mass on an abdominal CT. Endoscopy with endoscopic ultrasound (EUS) confirmed a submucosal mass. Biopsy of the lesion was consistent with a leiomyoma. The DaVinci robotic system was used for partial gastrectomy and reconstruction, with the addition of intraoperative ultrasound to localize the lesion intraoperatively. Pathological examination of the resected mass confirmed a diagnosis of leiomyoma with negative margins. There were no intraoperative or postoperative complications. The patient was discharged home on the second postoperative day. Intraoperative endoscopic ultrasound is a safe technique that may improve the success rate of surgery by confirming the location of the lesion. Robotic assistance in gastric resection offers an easy minimally invasive approach to such tumors. This approach can achieve adequate surgical margins and lead to short hospital stays.
