Stent type used does not impact complication rate or placement time but can decrease treatment cost for benign and malignant esophageal lesions

Double hitch stitch is a novel technique for fixation of tracheal stent in a case of tracheoesophageal fistula: a case report

Background

Caudal tracheal stent migration can be potentially life threatening by causing distal luminal obstruction. We present a rare double hitch stitch procedure (for prevention of migration of tracheal stent), which is an external fixation technique in a case of tracheoesophageal fistula with tracheal and esophageal self-expandable metallic stent (SEMS).

Case presentation

A 50-year-old male patient who presented with cough and dyspnea was a known case of carcinoma of the esophagus with esophageal stent in situ. Computed tomography (CT) scan showed tracheoesophageal fistula with esophageal stent (esophageal SEMS) migrating into the trachea. Tracheal stenting was done with SEMS. Patient was followed up after 1 month with recurrent complaints of cough on deglutition. On follow-up bronchoscopy, migration of stent was observed. A rare procedure of double hitch stitch was performed with fixation of the tracheal stent (tracheal SEMS) using a percutaneous anchoring stitch, embedded in the subcutaneous tissue. Follow-up bronchoscopy after 1 month of the procedure showed no migration of stent.

Conclusion

For the treatment of large tracheoesophageal fistula, stenting of both the trachea and the esophagus along with the double hitch stitch proved to be lifesaving. Stent migration prevention using “double hitch-stitch” is simple, safe, and successful, without any complications.

Investigating Esophageal Stent-Placement Outcomes in Patients with Inoperable Non-Cervical Esophageal Cancer

Background: Esophageal stent insertion in patients with inoperable esophageal cancer is usually accompanied with relatively high adverse symptoms and even mortality. The current study aims at investigating the outcomes of esophageal stenting in patients with inoperable non-cervical esophageal cancer. Materials and Methods: The current descriptive-analytical research evaluates 25 patients with esophageal cancer. The stent was placed in esophagus based upon endoscopy analysis with or without fluoroscopy and then the stent position and its opening was investigated by making use of CXRand Gastrografin studies. Demographic characteristics, dysphagia scores, stent placement side effects and the dysphagia-related indices were recorded and examined by taking advantage of a questionnaire which was administered pre and post stent insertion. Results: The study population was comprised of 15 women and 10 men. The individuals' average age was 69.20 ± 11.25 years. Dysphagia mean score was lowered from a value of 4.32 ± 0.80 to 2.00 ± 1.22 (P-value<0.05). The prevalent side effects were chest pain (64%), dysphagia recurrence (40%), stent blockage (20%), stent migration (16%), GI bleeding (8%), and malposition (8%). Also, it was found out that 64% of the patients survived for 6 months. Conclusion: The results indicated that although esophageal stenting is accompanied with side effects in patients with inoperable esophageal cancer, but it is the most frequently used and the most reliable method in relieving dysphagia and improving dysphagia-related life indices.
