Özet
Background: Free colon flap is the preferred method of hypopharynx reconstruction when the defect is substantial, or simultaneous voice reconstruction is planned. Most of the complications in free colon flaps are located at the anastomosis between colon and thoracic esophagus due to size mismatch of the lumen. We present our experience comparing a modified anastomosis technique and a conventional anastomosis technique at the distal end of interposed colonic segment. Methods: In this retrospective review, 94 patients, divided into two groups, underwent hypopharynx reconstruction. Group A (18 patients), conventional anastomoses between colon and thoracic esophagus was performed, while in Group B (76 patients), underwent the modified method of anastomosis. Results: The average follow-up period was 46 months in group A and 54 months in group B. Fistula formation was found in 2 patients from Group A, and 1 patient from Group B. Strictures were observed in 4 patients from Group A, and 1 patient from Group B. Difference between both groups regarding complications of leakage and stricture formation was statistically significant (p < 0.05). Conclusion: Modified method for anastomosis between colon and thoracic esophagus was found to be effective in the reduction of complications associated with the use of a free colon flap for hypopharyngeal reconstruction. Further advances of this technique could gain momentum in the future. (C) 2020 Asian Surgical Association and Taiwan Robotic Surgery Association. Publishing services by Elsevier B.V.
