Colonic perforation may occur as a complication of diagnostic and therapeutic colonoscopy. The risk factors for perforation after colorectal endoscopic submucosal dissection (ESD) include an inexperienced endoscopist, a large tumor size, and submucosal fibrosis. The mechanisms of perforation include unintended endoscopic resection/dissection and severe thermal injury. Here, we report a case of ...

In order to expand the availability of endoscopic submucosal dissection (ESD), measures to facilitate the procedure are necessary. When bleeding occurs, the examiner's field of vision is critically impaired, and ESD becomes less efficient and more hazardous because of the presence of submucosal hematoma and covered blood clot. We propose the use of polyethylene glycol (PEG) irrigation as a simp...

BACKGROUND Robotic thyroidectomy and conventional endoscopic thyroidectomy have not been thoroughly compared. In this study, we compared the potential advantages of robotic versus endoscopic thyroidectomy. METHODS We analyzed 218 consecutive patients who underwent endoscopic (105 cases) or robotic (113 cases) thyroidectomy using a gasless unilateral axillo-breast or gasless unilateral axillar...

RationaleCalcifying fibrous tumor (CFT) is a rare benign soft tissue mesenchymal neoplasm. Although the gastrointestinal (GI) tract is the most common predilection site of CFT, the clinicians, even including pathologist, generally consider it as GI stromal tumor (GIST) or other submucosal tumors such as schwannoma and leiomyoma. PatientconcernsA 55-year-old man presented with complaints of epig...

Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) have provided new alternatives for minimally invasive treatment of gastrointestinal adenomas and early-stage cancers that involve a minimum risk of lymph-node metastasis. The use of submucosal injections is essential to the success of these endoscopic resection techniques. The "ideal" submucosal injection solution sho...

BACKGROUND Endoscopic submucosal dissection (ESD) is accepted as a minimally invasive treatment for early gastric cancer, however, it is not widely used in the colorectum because of its technical difficulty. OBJECTIVE To determine the feasibility of using ESD for treating large superficial colorectal tumors. PATIENTS A total of 400 consecutive patients were treated by ESD for 405 lesions at...

Abstract Aims To assess management of early rectal cancers in octogenarians going through a regional Small and Early Rectal Cancer MDT observing oncological outcomes, morbidity, mortality quality life after treatment Methods Consecutive octogenarian patients treated via the SERC between Dec 2013 2019 were examined retrospectively from prospectively maintained database. Patients underwent transa...

t i i fi e t s s t I i The incidence of gastric cancer has steadily declined over many decades, yet it remains worldwide one of the most common malignancies.1 Most gastric cancers arise as a result of lifelong colonization with Helicobacter pylori, inducing chronic active gastritis. An abundancy of research over the past 20 years has yielded endoscopic and non-invasive methods to recognise both...
