1. The current practice of operating upon patients with varicose veins as the treatment of choice costs more than xi15 million a year. 2. The bulk of this expense is due to the length of time that patients are kept in the ward. If they were treated as outpatients, either by Fegan's method or by operation, the cost would be reduced to one-tenth of what is now spent. Even if the operation were done on a "short-stay" basis the cost would be reduced to one-third or less. 3. Although the long term results of Fegan's method are uncertain there is no doubt that it gives better immediate results than an operation. Moreover, there is no particular type of varicosity of shape of limb which precludes its use.
Certain aspects of the technique of injection sclerotherapy are illustrated in a series of 15 patients presenting with acute oesophageal variceal haemorrhage due to bilharzial hepatic fibrosis. The results of this form of treatment are shown. The actual process of variceal injection was done under visual fluoroscopic control, using a mixture of 76 per cent Urografin and 5 per cent ethanolamine oleate. The findings showed that: (a) the sclerosant did not reach the gastric varices which could be a possible source of re-bleeding; (b) intravariceally injected material rapidly escaped from the submucosal varices, where it should stay, to the peri-oesophageal veins; (c) sclerosant remaining on the variceal walls was minimal by the time the Sengestaken tube was inflated.

A prospective study was carried out on the efficacy of sclerotherapy for the treatment of hydrocoeles and epididymal cysts. Thirty-six hydrocoeles and 13 epididymal cysts were treated and followed up for between 1 and 2 years. Thirty-four hydrocoeles were cured, 1 failed to respond to treatment and 1 recurred after treatment. All 13 epididymal cysts were cured.
Compression bandages are normally applied for 6 weeks after sclerotherapy. The changes in pressure exerted by such bandages have been measured over 8 h. The results show that different surgeons applied bandages over a wide range of pressures but the range for each individual surgeon was surprisingly narrow. The pressure falls with time and approaches zero at 6--8 h of normal activity by the subject, but more slowly if the knee and ankle joints are excluded from the bandage. The initial pressures were higher when STD compression pads were used, although the rate at which the pressure fell was the same.

Oesophageal varices in 21 children with portal hypertension (intrahepatic 13, extrahepatic 8) were treated with sclerotherapy using ethanolamine oleate injected via a fibreoptic endoscope. Repeat endoscopy confirmed variceal obliteration in 18 children with a mean of 3.5 (range 1-8) injections. No patient has bled since obliteration of varices. Complications were oesophageal stricture (2 patients), oesophageal ulcer (5 patients) and haemorrhage within 3 days of injection (5 patients). The early results suggest that this is a satisfactory method for the treatment of oesophageal varices in children.
