[Reconstruction using pedicle and free flaps in partial or total resections of the hypopharyngeal-esophageal tract]

Modern surgical treatment of cancer of the hypopharyngo-esophageal cannot be conditioned by the reconstructive procedures. Reconstructive options are based on the size and position of the defect in this important anatomical region. Currently the reconstruction of the hypopharyngo-esophageal tract allows a rapid and suitable restoration of the vital functions, a low morbidity and shortened hospital stay. The purpose of this study was to compare the various reconstructive approaches in terms of morbidity and functional results. Between January 1990 and June 1994, 17 patients with hypopharyngo-esophageal tract malignancies and one with a stenosis received treatment. The reconstructive procedures included 19 flaps: five myocutaneous pectoralis major flaps, one myocutaneous trapezius flap, five deltopectoral flaps, one radial forearm free flap and seven free jejunal grafts. There were six complications: one total necrosis and two stenosis in the free jejunal grafts group, one partial necrosis and one dehiscence in two myocutaneous pectoralis major flaps and one stenosis in a deltopectoral flap. Based on our studies, we believe that the free jejunal graft is the first choice for total reconstruction of the hypopharyngo and cervical esophageal tract. However the radial forearm free flap is certainly a valid solution for subtotal hypopharyngo-esophageal reconstruction. Pedicled flaps and particularly the myocutaneous pectoralis major flaps are a good alternatives for limited reconstructions (< 50%) of the hypopharyngo-esophageal tract.
