    Abstract:
    OBJECTIVE: The objective of our study was to assess the technical feasibility and clinical effectiveness of expandable metallic stent placement in patients with nonanastomotic malignant jejunal obstruction after total gastrectomy with esophagojejunostomy. MATERIALS AND METHODS: We retrospectively analyzed data from 21 patients with malignant jejunal obstruction after total gastrectomy with esophagojejunostomy who received one of two types of expandable metallic stent. Clinical effectiveness was assessed using the following variables: technical and clinical outcomes, complications, dysphagia scores before and after stent placement, patient survival, and stent patency. Complications with related interventions were evaluated and compared between the two stent types. RESULTS: Stent placement was technically successful in 20 of the 21 patients (95%) with 19 of 20 patients (95%) showing symptomatic improvement. Type A stents were used in 10 patients and type B stents in the remaining 10 patients. Complications occurred with seven of 20 stents (35%) and involved stent migration (n = 3), tumor overgrowth (n = 3), or pain (n = 1). The dysphagia score before stent placement (mean ± SD, 3.2 ± 0.5) had improved by 3 days after stent placement (1.3 ± 0.9, p < 0.001) and was maintained compared with the initial score up to 1 month (1.7 ± 1.1, p < 0.001) and 3 months (2.1 ± 1.5, p = 0.021) after stent placement. The median patient survival and stent patency were 114 and 46 days, respectively. The type of stent was not significantly related to complications (p = 0.350). CONCLUSION: Placement of expandable metallic stents to treat nonanastomotic malignant jejunal obstruction in patients who have undergone total gastrectomy with esophagojejunostomy is feasible and clinically effective.
