[Bilio-enteric convergent diversion with an antireflux mechanism. An experimental study]. / Derivación bilioentérica convergente con mecanismo antirreflujo. Estudio experimental.

A new biliary-enteric derivation was used in one group of mongrel puppies to avoid reflux and its complications. A Y-en-Roux derivation in one pared group of puppies was used also. There was a substantial complications decrease in the first puppies, but do not stop at all contamination in the bile duct tree and liver.

[Behavior of the section and arterial suture site in growing subjects]. / Comportamiento del sitio de sección y sutura arterial en sujetos en crecimiento.

In order to investigate the possible unwanted late effects of vessel cicatrization during growth, especially after the section and terminal-terminal arterial anastomosis, a study was carried out in 28 piglets using three different surgical anastomosis techniques as well as three different types of sutures. Results show that the smaller the diameter of the vessel and when for its surgical correction suture techniques using separate and combined stitches are used, in addition to non absorbent material, a greater amount of suppression is seen at the site of anastomosis during arterial growth. Less suture material is recommended (of lesser thickness) as well as continuous suture techniques as the diameter of the vessels to be sutured decrease.
