Using a special stent to treat benign duodenal strictures

Official title: An Exploratory Clinical Study of Double Pig Tail Stent-assisted Fixation of Fully Covered Metal Stents for the Treatment of Benign Duodenal Strictures

Run by Jinling Hospital, China · NCT06736301 · Data updated 2026-11-12

This study is testing a special stent to see if it can help people with benign duodenal strictures feel better by keeping the narrowed area open and preventing the stent from moving out of place.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients under 75 years old with diagnosed benign duodenal strictures who have experienced symptoms of upper gastrointestinal obstruction and have not responded to multiple balloon dilations.

Probably not a fit

Patients with gastrointestinal perforation, malignant strictures, or severe comorbidities may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the use of a double pig-tail stent to assist in the fixation of fully-covered metal stents for patients suffering from benign duodenal strictures. The approach aims to minimize stent displacement and ensure effective expansion of the narrowed duodenal area, thereby alleviating symptoms associated with upper gastrointestinal obstruction. The study will evaluate both the safety and efficacy of this method, providing insights into its long-term effectiveness for treating this condition.

Why it matters

Potential benefit: If successful, this approach could significantly improve symptom relief and quality of life for patients with benign duodenal strictures.

How similar studies have gone: While this specific approach is novel, similar studies using stent-assisted techniques have shown promise in managing gastrointestinal strictures.
