Surgical closure of enlarged tracheoesophageal fistula after laryngectomy: A systematic review of techniques.

OBJECTIVES

The objectives of the study were (1) systematically review the data on surgical closure of enlarged tracheoesophageal fistula after laryngectomy and (2) to perform a comparison of reconstruction of surgical techniques.

METHODS

Systematic review was performed using PRISMA methodology. Cumulative patient data were compared between patients reconstructed with vascularized tissue (sternocleidomastoid fascia and muscle, pectoralis major, deltopectoral, radial forearm) and those closed primarily (two-layer, three-layer, and tracheal transposition).

RESULTS

Fourteen studies reported outcomes for the reconstruction of tracheoesophageal fistula. Primary closure was used in 98 patients, vascularized flap in 74, and occlusive device in 8. Vascularized flap resulted in successful closure of the fistula in 89 % of cases compared to primary closure in 62 % (p = 0.0003).

CONCLUSION

Systematic review of the literature supports an improved surgical closure rate with vascularized flap interposed between the esophageal and tracheal lumens compared to primary closure.
