Laparoscopic Transgastric Resection of a Gastric Submucosal Tumor near Esophagogastric Junction with Concomitant Sleeve Gastrectomy: a Video Case Report.

BACKGROUND: Over the past two decades, there has been a significant rise in bariatric surgery. As a consequence, the prevalence of obese patients with a combined gastric pathology such as a submucosal tumor (SMT) requiring excision at the same time as bariatric surgery is higher but the management remains controversial. We report the safety and effectiveness of a simultaneous laparoscopic transgastric resection of a large gastric SMT near the esophagogastric junction (EGJ) with sleeve gastrectomy (SG).

METHODS: We present a video report of a 52-year-old male (BMI = 49 kg/m2 ) referred for bariatric surgery, who was found to have a large SMT 2 cm from the EGJ on the lesser curvature on previous gastroscopy.

RESULTS: Using five ports placed for laparoscopic SG, the gastric SMT was localized through an anterior gastrotomy and fully excised using a linear stapler and the gastrotomy site was closed. SG was then performed over a 54Fr bougie, including the gastrotomy suture closure.

CONCLUSIONS: Several factors play important roles in deciding the best surgical approach for patients who are candidates for bariatric surgery and have concomitant gastric SMTs. This video report describes a safe and effective technique of simultaneous transgastric resection of a lesser curvature gastric SMT near the EGJ in a patient undergoing SG.
