[Comparing the free fasciocutaneous flap with free jejunium in reconstruction for hypopharyngeal and cervical esophageal defects]

Objective:To investigate the application of the reconstruction methods for hypopharyngeal and cervical esophageal defects due to the resection of hypopharyngeal cancer and advanced laryngeal cancer between free fasciocutaneous flaps and free jejunium transfer.We compared the superiorities and inferiorities of these two reconstruction methods. Method:Retrospective review of the archives of 56 patients from 2000 to 2010 who underwent pharyngoesophageal reconstruction with free flaps (n=32) or free jejunal transfer(n=24),comparison of indications,complications, hospitalization duration, swallowing function recovery and postoperative survival time. Result:The overall 3 year survival rate of free flap group and free jejunal transfer group was 59.3%,55.7% respectively; the overall 5 year survival rate was 38.5%,37.1% respectively. The overall rate of complication rate was 18.8%, 16.7% respectively. The patients with free flaps had higher incidence rate of fistula and scarring in the donor site and lower incidence rate of hues and stricture than the ones with free jejunal transfers. The mean hospitalization duration was (15.00±7.06) days and(13.00±6.75) days. The mean time of first oral food intake was(13.00±5.83)days and (11.00±6.67) days. The differences between two groups had no statistical significance(P>0.05). Conclusion:Free flaps and free jejunium transfer are the two most common reconstruction methods for the hypopharyngeal and cervical esophageal defects. Each has its own advantages and disadvantages respectively. We should choose reconstruction method according to the site and extent of the hypopharyngeal and cervical esophageal defects, preoperative and postoperative radiotherapy requirement.
