Morphometric parameters of ileal revascularized grafts of the cervical portion of the oesophagus in dogs.

Aims: Gradual elaboration of the operation technique for transplantation of ileal segments in the cervical esophagus. Comparison of clinical, histomorphological and biometric characteristics of ileal segments in the case of different types of autotransplantation.

Material and methods: The experimental investigation on autografting segments of the ileum (both flap and tubular variants) of the cervical esophagus was carried out on 87 dogs. There were five groups of dogs and five different operating techniques were used proceeding gradually from a simple one to a more complicated one.

Results: The successful esophagoplasty in dogs (87) needed multi-stage modelling for the elaboration is a more efficient surgical technique. Morphological factors of the graft in the relationship with the duration of graft ischaemia and the duration of the follow-up period (1-372 days) were analysed.

Conclusions: The use of ileum transplants is slightly more recommendable compared to jejunum transplants. Unfortunately even employing this method the results show moderate effect.
