title: Type of Combined Endoscopic Biliary and Gastroduodenal Stenting Is Significant for Biliary Route Maintenance.
abstract: Objective Some patients with malignant gastric outlet obstruction require combined biliary and gastroduodenal stenting (double stenting). However, biliary stent dysfunction can often disturb biliary route maintenance, thus making the optimal biliary stenting for these patients unclear. The present study was designed to assess the factors associated with the long-term maintenance of biliary drainage routes. Methods The clinical features and long-term outcomes were assessed in patients who underwent double stenting. Patients The outcomes were reviewed in 43 consecutive patients who successfully underwent endoscopic double stenting with metallic stents. Results An univariate analysis of all patients with biliary stent dysfunction showed the separate type of double stenting (two stents placed in a non-crossed position) to be the only predictive factor related to successful biliary re-intervention for stent dysfunction (odds ratio 73.67, p=0.001). A comparison of the clinical features in patients who underwent separate and cross (two stents placed in a crossed position) stenting showed the functional success rate to be higher for the separate (93.3%) than for the cross (61.5%) stent type, with the median times to biliary stent dysfunction differing significantly (330 vs. 298 days, respectively; p=0.048). The success rates of re-intervention in patients with separate and cross type stents were 88.9% and 0.0%, respectively (p=0.001), and the initial biliary route maintenance rates were 96.7% and 53.8%, respectively (p=0.002). Conclusion The separate type of double stenting may enhance successful biliary re-intervention for stent dysfunction and also maintain the initial drainage route longer. The biliary drainage outcomes should therefore be considered when choosing the type of double stenting.
