A single-center pilot study on the efficacy and safety of acetic acid–enhanced magnifying endoscopy with narrow-band imaging for diagnosis of colorectal epithelial neoplasms
Post written by Takeshi Shimizu, MD, from the Department of Gastroenterology, Sendai City Medical Center, Sendai, Japan. The focus of our study was to identify the ideal acetic acid (AA) concentration for AA-enhanced narrow-band imaging (NBI) magnifying endoscopy (ANBI-ME) in diagnosing colorectal epithelial neoplasms. We then compared its pit pattern diagnostic ability and diagnostic concordance with crystal …
Endoscopic resection of a giant pedunculated colonic polyp using a detachable snare and scissors-type knife
Post written by Sukit Pattarajierapan, MD, from the Surgical Endoscopy Colorectal Division, Department of Surgery, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand. A 60-year-old man presented with intermittent abdominal pain. An abdominal CT scan showed colocolonic intussusception of the sigmoid with a 50-mm polypoid mass as the leading point. We performed a colonoscopy and found a giant …
