A novel surgical method for acquired non-malignant complicated tracheoesophageal and bronchial-gastric stump fistula: the "double patch" technique.

Background: To manage the acquired benign complicated tracheoesophageal fistula (TEF) and bronchialgastric stump fistula (BGSF) are clinical technical challenge. The purpose of this study is to retrospectively review a surgical "double patch" technique in treating nonmalignant complicated TEF and BGSF, and then clarify the long-term curative effect of the technique. Methods: Clinical records of 30 patients with non-malignant complicated TEF and BGSF treated by "double patch" technique in Tangdu Hospital between August 2004 and August 2014, were analyzed and summarized retrospectively. Results: Thirty patients (19 males and 11 females) underwent "double patch" surgical repair of acquired benign complicated TEF and BGSF. The median age of the patients was 40.2 +/- 21.1 years. The most common causes were the following: TEF [22], BGSF [8]. Post-intubation injury [6], trauma [5], foreign body and stents [10], complications from prior esophageal surgery [8], and caustic ingestion [1]. The follow-up was completed for 24 months in all the patients (100%). The operative mortality was 0% (0/30). Twenty-six patients (86.7%) recovered uneventfully while four patients (13.3%) exhibited some major complications in the perioperative and postoperative periods. One patient (3.3%) developed recurrence of tracheal fistula in situ, two patients (6.7%) showed pneumonia, and one patient (3.3%) developed fistula esophageal anastomosis. All the 30 patients resumed oral intake finally. Conclusions: The double patch technique is an effective and safe method to repair the acquired nonmalignant complicated TEF and BGSF.
