[Segmentary necrosis of the main bile pathway. Presentation of a clinical case]

Reference is made to a personal case in an examination of the more controversial aspects of segmentary necrosis of the main bile pathway. Attention is drawn to the leading features of the pathogenetic evolution of this lesion. Bearing in mind the almost insurmountable difficulty of formulating a preoperative diagnosis, an examination is made of the possible therapeutic solutions. In the light of the data presented, the suggestion is made that the only effective prevention is offered by early surgical management of all pathological situations affecting the main bile pathway that may, if neglected, lead to the setting up of segmentary necrosis within it.
