Endoscopic laser-coagulation was used 94 times in 14 patients to stop gastro-intestinal bleeding or coagulate potential bleeding sources during non-bleeding intervals. Lasting haemostasis was achieved in three cases of incomplete gastric erosion, one of gastric ulcer, one of duodenal ulcer and one of bleeding after antral rugectomy. It failed to stop severe arterial bleeding in a case of gastric carcinoma. Lasting haemostasis was achieved in six haemangiomas of the colon, one case of angiomatosis of the antrum with 62 individual sites, two of angiodysplasia of the colon, 17 lesions in Osler's disease of the oesophagus (2 cases), stomach (10) and duodenum (5). The procedure was performed in the course of diagnostic endoscopy with an argon-ion laser developed by the authors, which has a density of 0.7-1.3 W/mm2. No complications have been observed so far.

We report clinical and laboratory findings in a large cohort of patients with thrombocytosis (357 cases). At the time of study, the patients showed a platelet number greater than 500 x 10(9)/L. The follow-up of patients ranged between 3 and 16 years. 123 patients were affected by polycythemia vera (PV), 97 by essential thrombocythemia (ET), 13 by chronic myeloid leukemia (CML) and 31 by myelofibrosis (MF). In 93 subjects, the thrombocytosis was reactive (ST). We found the highest incidence of thrombosis in PV patients, especially concerning the cerebro-vascular system; thrombosis, but in a lower percentage, was recognized in MF patients. Also, ET patients showed a number of thrombosis in peripheral arteries. Thrombosis of the coronary arteries were quite rare while 25% of MPD subjects showed peripheral vein thrombosis. We take into account that many patients showed thrombocytosis associated to one or more atherosclerotic risk factors. Hemorrhages were present especially in CML and in ET, but were not as frequent as thrombosis. The most common bleeding manifestations affected skin and mucosa. Hemorrhages after surgical procedures were also frequent. Gastro-intestinal bleeding was not strictly related to anti-aggregating therapy and occurred not only in PV but also in ET patients.

Hepatic hereditary telangiectasia in 2 females was treated with hepatic artery embolization. In one patient both peripheral and central arterial occlusion was performed; the patient died of massive gastro-intestinal bleeding for 2 months later. Autopsy showed extensive regions with necrosis in the right liver lobe. In the next patient only central occlusion of the right hepatic artery was performed and the arterio-venous shunting in the left liver lobe left remaining. After a long reconvalescence period the patient recovered completely. It is advocated to centrally occlude only that hepatic artery supplying the most affected parts of the liver in Osler's disease. Thus extensive necrosis with possible ensuing death may be avoided.
