[Gallbladder agenesis in the laparoscopic era: report of a case]

The authors report an observed case and re-examine the incidence of this defect; they underline the possibility of the diagnosis during the fetal age and the association with one o more defects, sometimes incompatible with the life; in the adult, on the contrary, may be evidence of an associated litiasic pathology of the ++epato-choledocus or of the stenosis of the oddian sphincter. On the base of the diagnostic previous experiences, they elaborate the proposal of an algorythm and underline the utility of a laparoscopic diagnosis either in the pre-operative doubious cases or in the intra-operative diagnosed cases.
