Percutaneous Enteral Access
摘要
Percutaneous enteral access devices aid in the management of malnutrition, benign and malignant gastrointestinal obstruction, and inflammatory conditions requiring diversion of enteric contents. The choice of enteral access depends on indication and operator preference and includes transoral (pull-type) and transabdominal (push-type) placement, small-bore and large-bore catheters, pre-pyloric and post-pyloric catheters, and transesophageal catheters. Radiologic and endoscopic techniques have replaced surgical techniques to insert the vast majority of percutaneous enteric catheters for ease of availability, low rates of complications, and high rates of technical success.
