Project description:Video 1We performed endoscopic submucosal dissection with the patient under conscious sedation. After making markings around the lesion, we incised the mucosa from the oral side of the ampullary lesion and dissected the submucosal layer using a Clutch Cutter. We created 2 submucosal tunnels to identify the dissection line of the ampulla. After completion of the tunnels, we performed a mucosal incision circumferentially and dissected the submucosal layer except the ampulla. Subsequently, we removed the ampulla directly above the muscle layer of the duodenum using the Clutch Cutter. En bloc resection was achieved. After resecting the lesion, a biliary stent and pancreatic stent were placed into the common bile duct and pancreatic duct, respectively. Prophylactic closure of the mucosal defect was performed using endoclips and a polyglycolic acid sheet with fibrin glue to prevent delayed perforation and bleeding.

Endoscopic submucosal dissection and tunneling procedures using novel image-enhanced technique.

Project description:Background and aimsRecent innovations in image-enhanced endoscopy allow early detection and management of GI lesions. In this study, we aim to analyze the utility of texture and color enhancement imaging (TXI) and red dichromatic imaging (RDI) during endoscopic submucosal dissection (ESD) and submucosal tunneling procedures.MethodsPatients who underwent ESD, submucosal tunneling endoscopic resection, and peroral endoscopic myotomy (POEM) using the novel imaging technique including TXI and RDI were included in the study.ResultsTwenty-five patients (13 male; age 43 ± 15.69 years) underwent POEM for achalasia (n = 20), submucosal tunneling endoscopic resection for esophageal subepithelial lesions (n = 3), and ESD for gastric neuroendocrine tumors (n = 2). All of the procedures were successfully performed. Mean procedure duration was 55.52 ± 21.61 minutes. TXI mode was used in all the cases, whereas RDI mode was used on 15 occasions. While using RDI mode, hemostasis was achieved in 1 attempt on 12 (80%) occasions. The site of mucosal incision was revised in 3 cases during POEM based on TXI and RDI modes.ConclusionsSubmucosal tunneling and endoscopic dissection procedures can be conveniently performed using a new image-enhanced technique. RDI is useful in localizing the site of bleeding during endoscopic dissection.
