Free jejunum transfers for functional reconstruction after tumour resections in the oral cavity and the pharynx: changes of morphology and function

Abstract

Oropharyngeal reconstruction following resections for locally advanced carcinoma by free jejunum transfer was studied in 31 consecutive cases over a period of 6 years, from 1988-1994. The most common site was the hypopharynx (n = 23). Reconstruction of the tonsillar region was performed in 5 cases and of the inner lining of the mouth in 5 cases. Two patients underwent neoglottic reconstruction, creating a tracheo-pharyngeal shunt. By use of an exteriorized jejunal segment for flap monitoring changes in morphology and function of a microvascular transferred denervated segment of jejunum could be monitored. The success rate was 94%. No evidence of fistula formation and local dehiscence were experienced in this series. Histological examinations showed some fibrotic changes 6 months after transplantation; lubrication and motility of the transplant were not severely altered. Biosynthesis, processing, and proteolytic activity of the jejunal epithelial cells were not impaired 2 weeks postoperatively.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
