We evaluated postoperative results in 49 patients (39 men, 10 women) who underwent pharyngoesophageal reconstruction with free-jejunal autograft following total pharyngolaryngoesophagectomy in the Department of Otolaryngology, Hokkaido University School of Medicine from 1989 to 1997. Evaluation was performed regarding the following points: 1) postoperative complications, 2) factors that determine the functional results of swallowing, 3) relation between forms of jejunal anastomosis and swallowing. The primary malignancy site was hypopharynx (39), cervical esophagus (4), larynx (3), thyroid (2) and trachea (1), Reconstructions were made with free jejunal autograft alone in 45 cases and with free jejunum in combination with gastric pull-up in 4. In patients who underwent reconstruction with jejunum alone, the anastomosis of the jejunum to the pharynx was performed in side-to-end fashion in 22, end-to-end in 18 and rho-shaped in 4. In the 1 remaining case, we used jejunal-patch graft. Postoperative complications including minor or nongraft related, occurred in 24 of 49 (49.0%) patients. Among these, graft-related complications were graft failure in 1 (2.0%), fistula formation in 3 (6.1%) and graft stricture in 2 (4.0%). Re-operations were required in one case of graft failure and 2 of fistula formation. Consequently, the overall graft-survival rate was 98.0% (48/49). Therefore, we considered the method of reconstruction to be a reliable procedure with a high-success rate. The swallowing function after reconstructive surgery was studied in 35 patients who underwent side-to-end (18) and end-to-end (17) anastomosis of the jejunum to the pharynx. We indicated that appropriate tension in the jejunum was the most important factor for adequate swallowing function. The end-to-end group had a higher rate of taking normal diet compared with the side-to-end group. The rate of swallowing dysfunction was only 5.9% (1/17) in the end-to-end group. On the other hand, 4 of 18 (22.2%) cases in the side-to-end group were regarded as having poor swallowing function. As a result we considered the end-to-end proximal jejunal anastomosis to be the more desirable form.
