Efficacy Test of Real-Time Upper Gastrointestinal Monitoring System

Efficacy Test of Real-Time Upper Gastrointestinal Monitoring System

A monitoring system was developed for detecting upper gastrointestinal (UGI) rebleeding. This system consists of (1) a tiny endoscopy, (2) a wearable device, and (3) a software. The endoscopy is inserted to UGI tract via nasal cavity and then stayed there for 3 days. The wearable device is set to regularly receive the pictures from the endoscopy and sent to the software, which is able to automatically analyze whether the rebleeding occurs. This study aims to test the feasibility and efficacy of the monitoring system.
