Pharyngo-oesophageal reconstruction with free jejunal transplants. New design of the upper anastomosis to improve monitoring of viability of transfer.

Since 1987, 13 free microsurgical jejunal transplants for large pharyngo-oesophageal tumors have been done in 12 patients at Tampere University Hospital. The conventional technique was used for the end to end upper anastomosis in seven patients, and our new end to side anastomotic technique in six. Five patients were alive at the time of writing, the mean survival being 22 months (range 1-48). Five patients developed orocutaneous fistulas, three of which healed spontaneously. In the remaining two the fistulas were caused by rapid recurrence of the tumour. There was no significant difference in ability to feed orally or swallow among the patients operated upon by the end to end or the end to side anastomotic technique. Our results show that the free microvascular jejunal transfer is a safe procedure for repair of the hypopharynx. Our new end to side hypopharyngojejunal anastomosis makes it possible to monitor the transplanted bowel reliably by direct vision.
