Because the wall of the diverticulum is very thin, carrying an extremely high risk of instrument perforation.

What is Gastroesophageal Reflux Disease (GERD)?

A chronic digestive disease where stomach acid or bile irritates the food pipe lining due to frequent relaxation of the lower esophageal sphincter (LES).
