Anatomical features of duodenal folds: a key feature to consider during endoscopic resection of duodenal neoplasms
Post written by Yoshimasa Miura, MD, PhD, from the Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan. This video shows an important point that duodenal folds have wide submucosal spaces but no muscularis. If endoscopists understand these characteristics, duodenal neoplasms can be successfully resected. It has been unknown for a long …
Impact of margin status on outcomes after endoscopic resection of well-differentiated duodenal neuroendocrine tumors
Post written by Shruti Mony, MD, from the Department of Gastroenterology, Johns Hopkins University, Baltimore, Maryland, USA. The focus of our study was to assess the recurrence patterns after endoscopic resection of nonampullary duodenal neuroendocrine tumors [DNETs]. Specifically, we wanted to identify the risk factors, effect of positive histologic margins, and optimal surveillance strategies including …
Outcomes of thermal ablation of the defect margin after duodenal endoscopic mucosal resection
Post written by Mayenaaz Sidhu, MBBS, from the Department of Gastroenterology and Hepatology, Westmead Hospital, and Westmead Clinical School, The University of Sydney, Sydney, Australia. Endoscopic mucosal resection (EMR) for large (>10-mm), sporadic, non-ampullary duodenal laterally spreading lesions (LSLs) is established as an effective treatment. However, one of the major limitations of EMR is the issue …
Successful duodenal endoscopic submucosal dissection using multiple clip-and-thread traction for a large tumor located in the duodenal bulb
Post written by Tomoaki Tashima, MD, PhD, from the Department of Gastroenterology, Saitama Medical University International Medical Center, Saitama, Japan. A 74-year-old man was referred to our institute for the treatment of a large flat-elevated tumor (diameter, 50 mm) in the duodenal bulb. We selected ESD for the en bloc resection of the lesion, and the …
A case of duodenal polyp at superior duodenal angle successfully treated by cap-assisted endoscopic mucosal resection
Post written by Ippei Tanaka, MD, from the Department of Gastroenterology, Sendai Kousei Hospital, Miyagi, Japan. A 72-year-old woman had a duodenal polyp at the superior duodenal angle (SDA). We performed cap-assisted endoscopic mucosal resection (EMRC) and successfully removed the lesion. Endoscopic observation and resection of duodenal polyps at SDA are extremely difficult because of …
A case of laparoscopy and endoscopy cooperative surgery for circumferential superficial nonampullary duodenal epithelial tumor
Post written by Osamu Dohi, MD, PhD, from the Department of Molecular Gastroenterology and Hepatology, Graduate School of Medical Science, Kyoto Prefectural University of Medicine, Kyoto, Japan. An 84-year-old woman had a circumferential SNADET that was detected during esophagogastroduodenoscopy. We performed laparoscopy and endoscopy cooperative surgery (LECS) with ESD technique and laparoscopic closure for the …
Endoscopic resection of a duodenal Brunner gland hamartoma presenting with GI bleeding
Post written by Tara Keihanian, MD, MPH, and Sunil Amin, MD, MPH, from the Department of Medicine, Division of Gastroenterology, University of Miami Miller School of Medicine, Miami, Florida. A 64-year-old man with multiple comorbidities presented to our hospital with a 3-day history of weakness, melena, and acute anemia. Upper endoscopy (EGD) showed a large …
Endoscopic closure assisted by a novel traction device after duodenal ESD
Post written by Tomoaki Tashima, MD, PhD, from the Department of Gastroenterology, Saitama Medical University International Medical Center, Saitama, Japan. A 58-year-old man was found to have a flat-elevated lesion of 20 mm in size in the second portion of the duodenum. We selected endoscopic submucosal dissection (ESD) for en bloc resection because endoscopic mucosal resection …
