Resolution of Bowel ObstructionNCT06997848
The Application of Ultrasound in the Evaluation of Patients With Colon Cancer-related Obstruction Receiving Colonic Stent Placement
An observational study of Resolution of Bowel Obstruction, run by National Taiwan University Hospital at 1 site in Taiwan.
Trial summary
Bowel ultrasound may serve as a diagnostic tool to detect the resolution of bowel obstruction. In this study, we aim to validate the use of bowel ultrasound to evaluate patients with colon obstruction receiving colonic stents at National Taiwan University Hospital from January 2010 to June 2023.

About this study
Bowel ultrasound may serve as a diagnostic tool to detect the resolution of bowel obstruction. In this study, we aim to validate the use of bowel ultrasound to evaluate patients with colon obstruction receiving colonic stents at National Taiwan University Hospital from January 2010 to June 2023. We will investigate the association between decompression of the ascending colon and the following surgical procedure, complication, and occurrence of bacteremia.
