Abstract
Endoscopic submucosal dissection (ESD) is reported to be an efficient treatment with a high rate of en bloc resection for large colorectal tumors in Japan and some other Western and Asian countries. ESD is considered less invasive than laparoscopic colectomy. However, ESD carries a higher risk of perforation than endoscopic mucosal resection (EMR). Various devices and training methods for colorectal ESD have been developed to solve the difficulties. In this review, we describe the complications of colorectal ESD and prevention of those complications. On the other hand, colorectal ESD is difficult for less-experienced endoscopists. The unique step-by-step ESD training system is performed in Japan. Additionally, appropriate training, including animal model training, for colorectal ESD should be acquired before working on clinical cases.

Endoscopic submucosal dissection (ESD) is reported to be an efficient treatment with a high rate of en bloc resection for large colorectal tumors in Japan and some other Western and Asian countries
ESD carries a higher risk of perforation than endoscopic mucosal resection (EMR) [7, 8] owing to its associated technical difficulties
We describe the complications of colorectal ESD, prevention of those complications, and training for the procedure
Summary
Endoscopic submucosal dissection (ESD) is reported to be an efficient treatment with a high rate of en bloc resection for large colorectal tumors in Japan and some other Western and Asian countries. The rate of en bloc resection for large colorectal tumors by ESD was reported to be 80–98.9% [1,2,3,4,5,6,7,8,9]. ESD carries a higher risk of perforation than endoscopic mucosal resection (EMR) [7, 8] owing to its associated technical difficulties. The colon is winding in nature and has many folds. The wall of the colon is thinner than the gastric wall. We describe the complications of colorectal ESD, prevention of those complications, and training for the procedure
