Injection sclerotherapy of oesophageal varices with the free-hand technique: experience in Hong Kong.
A prospective study of the efficacy of injection sclerotherapy with the free-hand technique for acute bleeding oesophageal varices was conducted, to evaluate its use in the control of acute variceal bleeding and to assess long-term sclerotherapy as the definitive treatment. Between July 1981 and January 1985, a total of 108 patients (96 men, 12 women with mean age of 54.4 years) had intravariceal injection of 5 per cent ethanolamine oleate. The majority had non-alcoholic cirrhosis and alcoholism accounted for only 18.5 per cent. There were 22 Child's A, 42 Child's B and 44 Child's C patients. During the 411 sessions of injection, major complications occurred in 12 patients (11.1 per cent) with 3 deaths. Of the 145 episodes of acute variceal bleeding 91.7 per cent were successfully controlled. In episodes which required more than one injection to control the bleeding, there was a high mortality of 75 per cent. Over the three and a half year period, 33 out of the 93 patients on long-term sclerotherapy had re-bled (35.5 per cent). Varices were obliterated in 27 patients with a mean of 5.4 injections. From our experience, the procedure is safe and effective. However, its status as a definitive treatment when compared with conventional surgical treatment requires further controlled evaluation.
