[Microsurgery applied to surgery of Vater's ampulla]. / La microchirurgie appliquée à la chirurgie de la papille de Vater.

Microsurgery, applied to surgery of Vater's papilla, does not represent a new development in surgical technique, but rather propounds the possibility of a new view of infundibular papilla which is of great diagnostic value of biliar disease. We see it as being indicated in all those cases in which surgery of papilla is undertaken. In papilla microsurgery technique exists a first period of diagnosis in which a study is made of the infundibula mucous membrane, allowing one to ascertain the state of the wall and possible affectation of the distal parts of the choledochus and of Wirsung ducts. In the second period, or the strictly surgical, microsurgery constantly achieves control of the papilla and its elements, at the same time being antitraumatic and more objective.
