We herein report three cases of the malignant esophageal stenosis successfully treated with the Niti-S™ esophageal stent. CASE 1: The hilar lung cancer and its mediastinal lymph node metastasis pressed the esophagus extramurally and caused the marked stenosis. CASE 2: A metastatic lymph node along the left laryngeal nerve caused the stenosis of the trachea. A primary esophageal lesion located at the middle thoracic esophagus also caused the marked stenosis. At first, tracheal stent was placed because of dyspnea, and two weeks later, we placed an esophageal stent. Case 3: Esophageal cancer at lower thoracic esophagus after definitive radiation therapy caused the marked stenosis. Because of the stenosis of esophago-gastric junction( EGJ), we used an esophageal stent with a long cover in order to prevent a reflux into the esophagus. This new Niti-STM esophageal stent was easy to place at the stenosis without difficulty using a conventional device. The symptom was improved immediately for each case. We hope this new device will be used widely.

Article Synopsis
  • Esophageal cancer ranks as the eighth most common type of cancer globally and is the sixth leading cause of cancer-related deaths.
  • The study introduces an innovative esophageal stent that features a wireless, battery-free, movable photodynamic therapy (PDT) unit, designed for flexible and precise treatment of esophageal tumors.
  • The system integrates a light source for PDT to induce tumor cell death and an electrochemical pneumatic actuator that allows for real-time positioning of the light source, improving targeted therapy based on tumor progression.

The management of gastrointestinal anastomotic leaks post surgery is a considerable challenge, characterized by elevated morbidity and mortality, particularly in cases of esophageal-jejunal anastomotic leaks. Diverse endoscopic intervention techniques have been utilized with enhanced success. We present a case where a 57-year-old patient with Siewert type II esophageal cardia cancer underwent endoscopic deployment of a fully covered stent into a fistula resulting from anastomotic leakage, following a laparoscopic proximal gastrectomy with Roux-en-Y and double tract reconstruction.

Esophageal stricture is the most common and disabling complication of esophageal injury caused by ingestion of corrosive substances. In our case, the patient developed esophageal stenosis due to ingestion of strong alkaline substances and underwent colon replacement surgery after repeated failed dilation treatments. After surgery, anastomotic stenosis and tracheocolonic fistula occurred successively, and the entire diagnosis and treatment cycle of this disease lasted for more than 20 years.
