Randomized Controlled Trial of Modified Nasobiliary Fixation and Drainage Technique

Area of Science:

• Gastroenterology
• Surgical Innovation
• Medical Device Technology

Background:

• Endoscopic nasobiliary drainage (ENBD) is crucial for managing biliary issues.
• Conventional nasobiliary fixation methods can lead to complications like unplanned extubation and tube blockage.
• Improving patient comfort during ENBD is an ongoing clinical challenge.

Purpose of the Study:

• To evaluate the clinical efficacy of a modified nasobiliary fixation and drainage technique.
• To assess the modified technique's impact on reducing unplanned extubation and tube blockage.
• To determine if the new method enhances bile drainage and patient comfort.

Main Methods:

• A randomized controlled study involving 230 patients undergoing ENBD from January 2019 to December 2020.
• Comparison between a control group (conventional fixation) and a test group (modified technique with standardized catheter length).
• The modified technique involved intraoperative annular cutting and a specific post-operative fixation method.

Main Results:

• The modified technique group showed significantly lower rates of unplanned extubation and complications.
• Higher rates of bilirubin decrease were observed in the test group, indicating improved bile drainage.
• Patient-reported discomfort was significantly reduced with the modified nasobiliary fixation technique.

Conclusions:

• The modified nasobiliary fixation and drainage technique offers significant benefits over conventional methods.
• This innovative approach effectively minimizes complications and enhances patient well-being during ENBD.
• Wider clinical adoption of this improved technique is recommended for better patient outcomes.
