The use of circular staplers for the treatment of haemorrhoids is a new technique that makes for better correction of the physiopathology of the condition, affords greater patient comfort and reduces health-care expenditure. This technique, which was invented by A. Longo in 1993, pulls up the haemorrhoidal cushions into their anatomical position, reduces or avoids postoperative pain, sparing the sensitive fibres of the anal canal, avoids anal canal stenosis and is not complicated by faecal incontinence. The authors present their experience in 41 patients affected by symptomatic haemorrhoidal prolapse and treated with a mucosal rectal prolapsectomy using a circular stapler. Each patient was followed up for 6 months to assess the incidence of complications and the degree of patient satisfaction. The results were compared with those reported in the literature, obtained using the Milligan-Morgan procedure. The Longo technique, which can be performed in the one-day surgery setting, allows very good relief of postoperative pain, rapid functional recovery and an early return to work, with a saving in health-care expenditure as compared with conventional treatment.

Picotamide, a new antiplatelet drug which has only slight effects on bleeding time, could be useful, in combination with oral anticoagulants, for the prevention of thromboembolic complications in patients with heart valve prostheses. We have evaluated in a randomized, controlled, double-blind, cross-over study, the effect of picotamide on the anticoagulant activity of warfarin. Administration of 300 mg t.i.d. for 10 days to 10 patients with aortic or mitral valve prostheses did not modify significantly either the level of anticoagulation or the mean daily dosage of warfarin. We observed a trend towards a reduction of plasma levels of beta-thromboglobulin. In conclusion the results of this study show that picotamide does not interfere with the anticoagulant activity of warfarin.

The platelet MDA production assay is widely used for studying platelet function and turnover. However, as original Stuart's method has low sensitivity, it is not accurate when MDA concentrations are very low. The effects of anticoagulants, incubation periods and clearing procedures were studied in an attempt to overcome this limitation and improve the sensitivity of this method. The results demonstrated that higher PCA and thrombin concentrations and a final addition of concentrated KOH increase the sensitivity of the method by almost eight fold. The higher transparency of the solutions, which is obtained through the sieving effect achieved by insoluble potassium perchlorate cold precipitation, is mainly responsible for the improvement.
