Temporary self-expandable metallic stent placement in post-gastrectomy complications

Self-expandable metallic stents in the upper gastrointestinal tract are used for treating malignant esophageal or gastroduodenal outlet obstructions and fistulas. Recently, self-expandable metallic stent use has been expanded to benign esophageal or gastroduodenal strictures and post-operative complications. However, there is scarce data available regarding efficacy, long-term complications, and outcomes with the use of self-expandable metallic stent in benign disease, especially post-gastrectomy complications.
Data of 57 patients who underwent upper gastrointestinal tract self-expandable metallic stent insertion for post-operative complications between March 2009 and June 2017 were analyzed. All patients underwent a curative gastrectomy for gastric cancer. Data collected included patient demographics, indication for procedure, type of stent used, complications, and patient outcomes.
Self-expandable metallic stent placement was technically successful in all patients. Of the 57 patients, 33 had self-expandable metallic stent placement for anastomosis site leakage, 12 for anastomosis site refractory stricture, and 12 for obstruction due to angulation. After self-expandable metallic stent placement, symptomatic improvement was achieved in 56 patients (98.2%), among which, three patients (5.4%) had recurrent symptoms, two underwent repeated stent insertion, and one underwent balloon dilatation. After self-expandable metallic stent placement, median time to initiating dietary intake was 6 days (range 1–30 days), and median duration of hospitalization was 13 days (range 3–135 days). At the follow-up (mean 24.6 months), migration was the most commonly reported complication, which developed in 15 (26.3%) patients.
Self-expandable metallic stent placement is an effective and safe treatment for post-gastrectomy anastomosis site leakage, stricture, and obstruction, which can decrease the risk of reoperation related mortality and modalities.
