Free Jejunal Flap for Pharyngoesophageal Reconstruction in Head and Neck Cancer Patients: An Evaluation of Donor-Site Complications

Abstract

Background Free jejunal transfer for pharyngoesophageal reconstruction has often been criticized for its associated donor-site morbidity. Conversely, the same argument has been invoked to support use of fasciocutaneous flaps, given their low incidence of donor-site complications. The purpose of the current study was to document donor-site complication rate with free jejunal flaps for pharyngoesophageal reconstruction, in the hands of an experienced surgeon.

Methods A retrospective chart review was performed for consecutive patients who underwent free jejunal transfer between 1992 and 2012 by the senior author (P.G.C.). Demographic data, abdominal complications, surgical characteristics of small bowel anastomoses, and postoperative bowel function were specifically noted.

Results Overall, 92 jejunal flap reconstructions were performed in 90 patients. The mean follow-up time was 29 months. Twelve (13%) patients had prior abdominal surgery. Donor-site complications included ileus (n = 2), wound cellulitis (n = 1), wound dehiscence (n = 1), and small bowel obstruction (n = 1). Mean time to initiation of tube feeds after reconstruction was 5 days. A total of 77 (86.5%) patients were discharged on an oral diet. The perioperative mortality rate of 2% was not associated with any donor-site complication.

Conclusion Free jejunal transfer is associated with minimal and acceptable donor-site complication rates. The choice of flap for pharyngoesophageal reconstruction should be determined by the type of defect, potential recipient site complications, and the surgeon's familiarity with the flap. Potential donor-site complications should not be a deterrent for free jejunal flaps given the low rate described in this study.
