Effects of colorectal endoscopic submucosal dissection on postoperative abdominal symptoms: a prospective observational study

Abstract

Endoscopic submucosal dissection (ESD) is an effective procedure to resect large superficial gastrointestinal neoplasms. In gastric ESD, several studies showed the relationship between postoperative abdominal symptoms and endoscopic treatment. However, the influence of colorectal ESD on abdominal symptoms after treatment is still unknown. To the best of our knowledge, this is the first prospective multicenter study performed to investigate the impact of colorectal ESD on postoperative abdominal symptoms. This study aimed to clarify the association between change of abdominal symptoms and ESD.
