Feasibility and safety of endoscopic submucosal dissection for lower rectal tumors with hemorrhoids

Abstract

ESD on lower rectal lesions with hemorrhoids could be performed safely, similarly to that on rectal lesions extending to the dentate line without hemorrhoids. In addition, all hemorrhoids after ESD improved to various degrees, depending on the resection range.

Feasibility of the lidocaine injection method during esophageal endoscopic submucosal dissection

“…This agent is used in upper gastrointestinal endoscopy to suppress the pharyngeal reflex. The effectiveness of lidocaine during ESD was recently reported . First, a local injection of lidocaine was used for pain relief when a rectal lesion extending to the dentate line was treated by ESD .…”

“…[10][11][12][13] First, a local injection of lidocaine was used for pain relief when a rectal lesion extending to the dentate line was treated by ESD. 10,11 In another study, it was reported that submucosal injection of local anesthetic during gastric ESD reduced post-ESD pain. 12,13 We believe that the benefit of LIM is the suppression of body movements during ESD by local analgesia.…”

“…It is used in upper gastrointestinal endoscopy to suppress the pharyngeal reflex. Topical anesthetics have been injected into the submucosal layer for intra‐ or post‐ESD pain in the stomach and colon . In addition, lidocaine prevents local intestinal spasms .…”

“…Topical anesthetics have been injected into the submucosal layer for intra-or post-ESD pain in the stomach and colon. [10][11][12][13] In addition, lidocaine prevents local intestinal spasms. [14][15][16] These effects of lidocaine may aid in sedation during esophageal ESD.…”
