Recurrent oesophageal cancer complicated by tracheo-oesophageal fistula: improved palliation by means of parallel tracheal and oesophageal stenting.

Objectives: Recurrent oesophageal carcinoma complicated by the development of a tracheo-oesophageal fistula is a crushing condition. In this situation, endoscopic double stenting may provide a quick and safe option for palliation.
Methods: The outcomes of patients who received endoscopic parallel stent implantation for tracheo-oesophageal fistula due to recurrent oesophageal cancer at a German tertiary referral hospital between 2006 and 2013 were reviewed in a retrospective case study.
Results: A total of 9 patients were identified (mean age 59.9 years). Tumour entity was squamous cell carcinoma, adenocarcinoma and neuroendocrine cancer of the oesophagus in 5, 3 and 1 case, respectively. The mean interval between primary treatment and recurrence was 19.2 months. Successful double-stent placement was always feasible. Complete closure of the communication between oesophagus and respiratory system was accomplished in all cases by stent implantation. There were no stent-associated complications. The mean survival following stent insertion was 64 days (6-121 days). After successful double stenting, 5 patients were fit enough to receive palliative chemo- or radiotherapy. Seven patients were finally discharged home after adequate oral intake had been achieved. Fatal aspiration pneumonia with respiratory failure occurred in 2 cases.
Conclusions: Endoscopic parallel stent implantation provides an easy and ubiquitous available technique for closure and palliation of tracheo-oesophageal fistula caused by recurrent oesophageal cancer. Immediate sealing of the fistula and relief of symptoms related to aspiration is achieved while hazardous operations are avoided. Therefore, we recommend endoscopic parallel stent insertion as the treatment of choice in case of tracheo-oesophageal fistula caused by recurrent oesophageal cancer.
