Trangastric endo-organ resection of a proximal gastric lesion.

INTRODUCTION: Gastric tumors confined to mucosa and submucosa can be resected with endoscopic resection techniques. They include endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) [1, 2]. These techniques can be challenging when the tumor is large or is near the gastroesophageal (GE) junction. Transgastric resection is a novel technique of removing gastric tumors that are unresectable by endoscopy due to their size and location. MATERIALS AND METHODS: We present a case of a 41-year-old male where a suspicious appearing lesion near the GE junction was removed using combined trans-gastric laparoscopic and endoscopic technique. The stomach was inflated using endoscopy, and three 5-mm balloon-tipped trocars were inserted directly into the stomach. The lesion was lifted with submucosal injection of saline and was resected using ultrasonic dissection device. The specimen was retrieved using Rothnet through the endoscope. The mucosal defect was closed with absorbable sutures. Trocars were removed and gastrostomy sites were closed with Endostitch device. Swallow study done on post-op day 2 did not show any signs of leak. Patient was discharged home on post-op day 5. Final pathology was consistent with hyperplastic polyp. CONCLUSION: Proximal Gastric lesions can be safely removed with combined Laparoscopic trans-gastric and endoscopic approach.
