Abstract
Treatment of cancer of the cervical aerodigestive tract is challenging due in part to the difficulty in reestablishment of pharyngoesophageal continuity after resection of the involved tract. From May 1989 to August 1990, six patients underwent immediate reconstruction utilizing microvascular transfer of free radial forearm flaps following resection of pharyngoesophageal neoplasms. A small island flap connected to the radial vascular pedicle by fasciocutaneous branch was used to monitor the vascular condition of the hidden fabricated free forearm flap. Stricture is the most troublesome complication of esophageal reconstruction using a conventional free forearm flap. Two small triangular flaps were designed and inserted bilaterally in the distal anastomosis of both lateral esophageal walls to prevent circular contracture. The outer layer sutures were anchored to surrounding rigid structures to withstand shrinkage and circular contraction. The problem of stricture was solved by these procedures. This one-stage, easily monitored operation for pharyngoesophageal reconstruction is considered to be as useful as a free jejunal transfer.
