The endoscopic resection of rectal neuroendocrine tumors (NETs) results in good long-term outcomes [1]. Many techniques for the endoscopic resection of rectal NETs have been described, including polypectomy, endoscopic mucosal resection (EMR), and recently EMR with band ligation [2], endoscopic submucosal dissection [3], and even transanal endoscopic microsurgery [4]. Underwater endoscopic rese...

BACKGROUND/AIMS Delayed bleeding is a major complication of endoscopic submucosal dissection. Second-look endoscopy is routinely performed in most hospitals to reduce the possibility of delayed bleeding without solid evidence to support this practice. The aim of this study was to evaluate whether second-look endoscopy prevents delayed bleeding, and to verify clinicopathological features of dela...

PURPOSE We report the performance of natural orifice transluminal endoscopic surgery (NOTES) low anterior resection in animals using transanal total mesorectal excision (TME) with laparoscopic assistance and endoscopic inferior mesenteric artery (IMA) dissection. METHODS Four pigs weighing 45 kg each, and one dog weighing 25 kg, underwent surgery via a transanal approach. The rectum was occlu...

PURPOSE To compare medical costs of endoscopic submucosal dissection (ESD) and transanal endoscopic microsurgery (TEM) for the treatment of rectal tumors. METHODS The records of 80 patients who underwent ESD and 32 who underwent TEM for the treatment of rectal tumors were collected. Factors compared in the two groups included patient age, sex and clinical characteristics, as well as hospital ...

Purpose This study aimed to compare short-term postoperative and oncologic outcomes of a transanal endoscopic total mesorectal excision (TME) to those of a transabdominal robotic TME. Methods A total of 62 patients with rectal cancer underwent transanal (n = 26) or robotic (n = 36) TME between June 2013 and December 2014. After case-matching by tumor location and TNM stage, 45 patients were i...

Gastrointestinal subepithelial tumors (SETs) are generally found during endoscopy and their incidence has gradually increased. Although the indications for the endoscopic treatment of patients with SETs remain to be established, the feasibility and safety of endoscopic dissection, including the advantages of this method compared with surgical treatment, have been validated in many studies. The ...

Abstract Purpose of Review Gastrointestinal endoscopy includes a wide range procedures that has dramatically evolved over the past decades. Robotic and artificial intelligence are expanding horizons traditional techniques will play key role in clinical practice near future. Understanding main available devices is unmet need. This review aims to assess current future applications most recently d...

Endoscopic submucosal dissection (ESD) procedure is composed of circumferential mucosal incision and submucosal dissection. A variety of endoscopic accessories are required to perform mucosal incision and submucosal dissection safely. As a result of the improvements in ESD devices and peripheral equipment and development of the ESD technique, ESD procedures have been performed extensively world...

Mucosal protective agents may improve healing of patients with endoscopic submucosal dissection-induced ulcers. The present study systematically evaluated published clinical trials to determine whether combined therapeutic use of mucosal protective agents and proton pump inhibitors can improve the outcome of patients with endoscopic submucosal dissection-induced ulcers compared to treatment wit...
