Management of bleeding liver tumours in Hong Kong.

A retrospective study was undertaken of 41 patients diagnosed as having suffered spontaneous liver rupture over a 4-year period to identify the clinical features, treatment and outcome of this complication in an area in which hepatocellular carcinoma is endemic. Two patients were excluded with a revised diagnosis of haemorrhagic malignant ascites. Of the remaining 39 patients, 37 bled from ruptured hepatocellular carcinoma, one from peliosis hepatis and multiple liver cell adenomas, and one from a malignant hepatic epithelioid haemangioendothelioma. Analysis showed that 59 per cent of patients were in shock on admission and that all but two of the 37 patients with ruptured hepatocellular carcinoma were men with cirrhosis. The association with cirrhosis was significantly higher than in a series of 45 patients with hepatocellular carcinoma undergoing elective resection during the same period (P less than 0.05). Treatment consisted of supportive care only in two patients, angiographic embolization in four, emergency liver resection in 11 of whom six died, hepatic artery ligation in 12 of whom eight died, and suture and/or packing in eight of whom six died. One patient died at laparotomy and in another patient bleeding was successfully arrested by intratumoural injection of absolute alcohol. Because of the high operative mortality of emergency surgery in these poor risk patients, prospective evaluation of emergency angiographic embolization is required.

Fatal haemoperitoneum due to liver metastases from nasopharyngeal cancer.

Spontaneous rupture of hepatic metastases is rare, there being only 22 cases documented in the literature. We report here the first such case due to nasopharyngeal carcinomatous metastases. This is of interest because in South East Asia ruptured hepatocellular carcinoma is the usual cause of spontaneous fatal haemoperitoneum.

Fatal haemoperitoneum as a result of liver metastases from nasopharyngeal cancer.

Spontaneous rupture of hepatic metastases is rare, there being only 22 cases documented in the literature. We report here the first such case owing to nasopharyngeal carcinomatous metastases. This is of interest because in South East Asia ruptured hepatocellular carcinoma is the usual cause of fatal haemoperitoneum.

Spontaneous rupture of hepatic epithelioid haemangio-endothelioma.

A 69 year old man presented with haemoperitoneum due to spontaneous rupture of a hepatic epithelioid haemangio-endothelioma. The tumour was found by ultrasound and coeliac angiogram to be locally advanced, involving both lobes of the liver. The bleeding was stopped by transcatheter arterial embolization. The diagnosis was established 4 weeks later by a Trucut biopsy under ultrasound guidance. The patient refused further treatment by radiation and chemotherapy, so he was observed closely. Chest radiography carried out 3 months later revealed multiple pulmonary secondaries. Despite his disseminated disease, he was well and enjoying a normal active life 4 months after embolization.
