Novel Plastic Stent With an Integrated Delivery System for Endoscopic Transpapillary Gallbladder Stenting: A...

Area of Science:

• Gastroenterology
• Medical Devices
• Surgical Innovation

Background:

• Endoscopic transpapillary gallbladder stenting (EGBS) is an alternative treatment for acute cholecystitis.
• Existing stent systems may have limitations in delivery and anatomical fit.

Purpose of the Study:

• To evaluate the feasibility and clinical outcomes of a novel, integrated stent system for EGBS.
• To assess the safety and efficacy of this new device in patients with acute cholecystitis.

Main Methods:

• Retrospective analysis of clinical data from 24 consecutive patients undergoing EGBS with the novel stent system.
• Data collected between April 2023 and March 2025.
• Evaluation of technical success, clinical success, and adverse events (early and late).

Main Results:

• Technical success rate of stent insertion was 95.8%.
• Clinical success rate for acute cholecystitis was 94.7% in technically successful cases.
• Early adverse event rate was 4.2%; late adverse event rate was 10% (including pancreatitis and gallbladder perforation).
• No cases of recurrent cholecystitis or stent migration observed.

Conclusions:

• The newly developed integrated stent system is feasible for EGBS.
• The novel stent system achieves good clinical outcomes with acceptable safety profiles.
• This device offers a promising option for managing acute cholecystitis via EGBS.
