Ruptured hepatocellular carcinoma: an important cause of spontaneous haemoperitoneum in Italy.

Objective: To evaluate the incidence of rupture of the tumour with intraperitoneal bleeding in a series of patients with hepatocellular carcinoma and its relative incidence as a cause of spontaneous haemoperitoneum, and to evaluate the results of the surgical treatment of a consecutive series of patients who presented with spontaneous haemoperitoneum caused by ruptured hepatoma.

Design: Retrospective study.

Setting: University hospital, Italy.

Subjects: 8 patients whose hepatocellular carcinoma ruptured (out of a total of 518) and caused spontaneous haemoperitoneum, and 34 patients who were admitted with spontaneous haemoperitoneum.

Interventions: Seven hepatic resections; in one case direct haemostasis was attempted because of the poor hepatic reserve.

Results: Rupture of the tumour with intraperitoneal bleeding occurred in 8/518 (2%) of cases of hepatocellular carcinoma. Ruptured hepatocellular carcinoma was the second most common cause of spontaneous haemoperitoneum (8/34; 24%), after gynaecological diseases (15/34; 44%). Of the 7 patients who presented with ruptured hepatocellular carcinoma and were treated by hepatic resection, 3 are alive (one with a recurrent disease) after a mean follow-up of six months (range 3 to 12 months) and 4 died of carcinomatosis within 12 months. The patient for whom resection was not feasible died immediately postoperatively of irreversible shock.

Conclusions: Rupture of hepatocellular carcinoma is a relatively common cause of spontaneous haemoperitoneum. Diagnosis at the onset of symptoms has important therapeutic implications: as the results of surgical treatment are unsatisfactory, other procedures with the limited goal of achieving satisfactory haemostasis can be considered if the hepatocellular carcinoma has been diagnosed.
