Follow-up evaluation for benign stricture of upper gastrointestinal tract with stent insertion

To determine the best method for benign stricture of the upper gastrointestinal tract (UGIT) with stent insertion by follow-up evaluation.

A total of 110 stents insertions were performed in 110 cases of benign stricture of the UGIT. Permanent (group A) and temporary (group B) placement of an expandable metal stent in 30 cases and 80 cases respectively. All cases were completed under fluoroscopy.

In group A, 30 uncovered or antireflux covered or partially covered expandable metal stents were placed permanently. In group A, 5 cases (16.7%) in 3-months, 5 cases (20.0%) in 6-months, 6 cases (25%) in the 1st year, 6 cases (50%) in the 3rd year, and 4 cases (80%) in the 5th year exhibited dysphagia relapse. In group B, a partially-covered expandable metal stent was temporarily placed in each patient and removed after 3-7 days via gastroscopy. Follow-up data in this group showed that 8 cases (7.5%) in 3-months, 9 cases (12.0%) in 6-months, 10 cases (15.4%) in the 1st year, 6 cases (20%) in the 3rd year, and 3 cases (25%) in the 5th year exhibited dysphagia relapse. The placement and withdrawal of all stents were all performed successfully. The follow-up of all cases lasted for 3-99 months (mean 41.6+/-19.7 months).

The best method for benign stricture of UGIT with stent insertion is temporary placement of a partially-covered expandable metal stent.
