Niti–S™ Esophageal Stent Effectiveness in Treating Malignant Esophageal Stricture:A Case Report

Abstract

Esophageal stents are often used in treating malignant esophageal stricture, but may occasion insertion difficulties. We report a case in which a new Niti–S™ esophageal stent model with improved maneuverability gave encouraging results.
An 80–year–old woman seen for dysphagia had esophageal stricture secondary to pulmonary carcinoma from the hilus pulmonis to the mediastinum. Esophageal intubation using a Niti–S™ stent enabled food ingestion and easy insertion and well maintained indwelling due to an external delivery diameter of 16.5 F (5.4 mm). Within 15 minutes of stent insertion, stricture symptoms were immediately relieved. The woman was thereafter able to ingest rice gruel until dying of the primary disease 2 months postoperatively.
These advantages of the new indwelling Niti–S™ stent solved marked stricture problems until then controlled only with difficulty using conventional devices, promising increased use of this device for esophageal intubation.
