Endoscopy: Safety and efficacy of colorectal endoscopic submucosal dissection.

摘要

Endoscopic submucosal dissection (ESD) is a safe and very effective alternative to surgery for the treatment of colorectal tumors, reports a new study from Japan. Surgery has been the only available treatment for colorectal tumors for a number of years. ESD, a minimally invasive modality that facilitates the one-piece resection of large superficial tumors, is an accepted treatment for gastric tumors, but hasn't been widely used for colorectal tumors. The lack of use of this technique in the colorectal setting is attributed to technical difficulty and concerns about an increased risk of perforation and resultant peritonitis. Small studies have previously examined the efficacy of ESD in this setting, but such studies have included limited numbers of patients, have involved single centers and assessed single operators.
