title: Laparoscopic Transgastric Enucleation of a Gastric Leiomyoma near the Esophagogastric Junction and Concomitant Sleeve Gastrectomy: Video Report.
abstract: BACKGROUND
  Obesity and bariatric surgery (BS) are increasing worldwide and can potentially lead to incidental diagnosis of benign gastric tumor including gastric leiomyoma (GL). When indicated, local tumor enucleation, completed through laparoscopic minimal-invasive approaches, has proven to be safe and effective especially when located near the esophagogastric junction (EGJ) with limited morbidity as compared to partial or total gastrectomies. Little is known regarding the most appropriate strategy concerning the management of GL regardless of the location in patients' candidate for BS.
  
  
  METHODS
  We present the case of a 67-year-old morbidly obese woman. She presented with an incidental 3-cm GL developed near the EGJ and antral histologic abnormalities mandating a gastric follow-up. Therefore, we performed both laparoscopic transgastric enucleation and sleeve gastrectomy simultaneously.
  
  
  RESULTS
  After identification of the lesion, the gastrocolic ligament was divided and a gastrotomy was performed along the greater curvature to expose the tumor. Once the submucosal plan was identified, the lesion was enucleated from the submucosamuscle junction. After closure of the mucosal defect and ensuring the absence of gastric wall perforation, a conventional laparoscopic sleeve gastrectomy was performed. No adverse outcomes occurred during the post-operative period. The final pathologic diagnosis showed a completely resected and benign leiomyoma.
  
  
  CONCLUSIONS
  Herein, we report the first laparoscopic transgastric enucleation of a GL localized close to the EGJ performed concomitant with a sleeve gastrectomy. This combined approach appeared feasible, safe, and do not compromise the access to the GI tract as well as potential future curative treatments on the gastric sleeve.
