[A rare complication of anticoagulants: hemoperitoneum caused by gallbladder rupture. Review of the literature apropos of a case].

A 78 year old woman presented with a hemoperitoneum due to vesicular rupture, a rare event since only 45 similar cases have been reported and only 2 of these, as with the present case, were on anticoagulants. This clearly illustrates the extreme rarity of the accident involving a treatment that is being used with increasing frequency. Diagnosis was never made before laparotomy, and the outcome was fatal in 20 of these 46 patients, mortality being higher before progress in intensive care and in patients over 50 years.
