A new designed self-expandable metal stent for the management of benign radiotherapy-induced hypopharyngeal or cervical esophageal strictures.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
aimsThe management of patients with hypopharyngeal or cervical esophageal refractory benign strictures (RBS) after surgery and radiotherapy ± chemotherapy for laryngeal cancer is challenging. We aimed to assess the long-term efficacy and safety of a new designed fully covered SEMS in these patients.
methodsWe reviewed the results of a prospectively collected database of 40 consecutive patients with dysphagia due to RBS of the cervical esophagus or hypopharynx after surgery and radiotherapy with or without chemotherapy for laryngeal cancer, unfit for surgery, referred in two tertiary-care endoscopic centers from June 2005 to December 2018. All of them were treated with placement of a Niti-S Conio cervical stent.
resultsAfter placement of the first stent, dysphagia improved in all patients. The total number of adverse events was 35 out of a total of 299 procedures (11.7%): 25 (8.4%) stent migrations, 6 (2%) tumor overgrowth, 3 severe pain and 1 pharyngo-cutaneous fistula. Stents were periodically changed. In only one patient with a cervical esophageal stricture the stent was definitively removed after 7 sessions of stent placement because of stricture resolution. Patients were followed-up for a median of 11.6 months and a significant improvement in dysphagia was reported in all patients (p < 0.001).
conclusionsThe use of this conformable, small caliber new designed Niti-S stent, exchanged periodically, appeared safe and permitted durable oral intake in patients with difficult-to-treat hypopharyngeal or cervical esophagus strictures, avoiding the need for periodic dilations.
