[Carcinoma of the hypopharynx: reconstruction of the pharyngo-esophageal tract after circular pharyngectomy by the transplantation of a U-shaped jejunal loop to the neck].

Reconstruction of the oro- and hypopharynx has specific difficulties duo to their wide diameters. Thirteen patients underwent reconstruction with a free U-shaped jejunal transplant, after circular pharyngo-laryngectomy for hypopharyngeal cancer invading the oropharynx. This transplant included a side-to-side anastomosis between the two limbs of the jejunal loop and allowed reconstruction of the upper digestive tract after wide carcinologic resection of the pharynx. The U-shaped jejunal transplant facilitated the upper anastomosis, especially the upper part where the resection involved the oropharynx. It formed a reservoir behind the tongue and avoided nasal reflux. Best indication are large resections involving the oropharynx.
