Gastric GIST full thickness resection aided by pulley traction

Le résumé fourni par la source

Text The authors present two gastrointestinal stromal tumors, one located in the fundus (5 cm) and the other in the gastric body (3 cm), removed by endoscopic full-thickness resection. CT scan and endoscopic ultrasound showed fourth layer lesions without local invasion. A needle-tip (DualKnife J, Olympus, Japan; Bipolar knife, AGS, China) and insulated-tip (IT-nano, Olympus) knifes were used for dissection. Exposure of muscularis propria attachment and deeper plane dissection was facilitated by a pulley traction with elastic band, fishing-line and TTS clips (Creo Medical, UK). The defects, showing peritoneal fat and the liver, were closed using two side-by-side OTS-clips (Ovesco, Germany). There were no complications. Pulley traction and OSTC clips are useful tools for faster and safer full-thickness endoscopic resection of subepithelial lesions, including larger lesions in difficult locations.
