Endoscopic submucosal dissection for colorectal neoplasms: a review

Area of Science:

• Gastroenterology
• Endoscopic Surgery

Background:

• Colorectal endoscopic submucosal dissection (ESD) expands endoscopic treatment options for low-metastatic potential lesions.
• ESD allows en bloc resection, reducing local recurrence rates compared to piecemeal endoscopic mucosal resection.

Purpose of the Study:

• To review the methods, devices, and training for colorectal ESD.
• To highlight the indications, technical challenges, and complications of colorectal ESD.

Main Methods:

• Review of existing literature on colorectal ESD techniques and outcomes.
• Discussion of device types and necessary endoscopist training.

Main Results:

• ESD is beneficial for large rectal lesions, improving patient quality of life.
• Colorectal ESD is technically challenging, with longer procedure times and higher perforation risks than gastric ESD.

Conclusions:

• Understanding ESD indications, techniques, and complications is crucial for its broader application in colorectal neoplasm treatment.
• Further training and standardization are needed to overcome barriers to colorectal ESD adoption.
