Introduction:
Biodegradable biliary stents (BDBSs), fully covered self-expanded metal stents (FCSEMSs) and multiple plastic stents (MPSs) were common stents in endoscopic treatment of benign biliary stricture (BBS).
Aim:
To evaluate the effectiveness of these 3 stents in BBS management.
Material And Methods:
The PubMed, Web of Science, Cochrane Library, and Wiley Library databases were searched for studies that provided data about BBS and stent therapy.
Results:
We found that BDBSs were associated with the highest clinical success rate (0.76, 95% CI: 0.71-0.80), followed by MPSs (0.69, 95% CI: 0.63-0.74), and FCSEMSs (0.67, 95% CI: 0.63-0.71). BDBSs also had a relatively high probability of technical success, at 1.00 (95% CI: 1.00-1.00), superior to MPSs (0.95, 95% CI: 0.88-0.99) and FCSEMSs (0.90, 95% CI: 0.85-0.94). The treatment success rate for BDBSs (1.00, 95% CI: 1.00-1.00) was also higher than for MPSs (0.88, 95% CI: 0.72-0.98) and FCSMESs (0.82, 95% CI: 0.76-0.87). However, BDBSs had the highest stricture recurrence rate (0.21, 95% CI: 0.16-0.26), compared with FCSEMSs (0.11, 95% CI: 0.08-0.15) and MPSs (0.07, 95% CI: 0.03-0.13).
Conclusions:
Patients with BBS are likely to receive a satisfied outcome when treated with BDBSs.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
