Abstract
We have assessed the value of the BICAP electrocoagulation probe in reducing the incidence of further bleeding in patients with upper gastrointestinal haemorrhage. One hundred and twenty-nine patients were studied in a prospective randomized controlled trial. There were 85 male and 44 female patients, age range 16–92 years. Forty-five patients had stigmata of recent haemorrhage (visible vessel or spot) and were randomized during endoscopy to 24 control and 21 treatment patients. Seven control patients rebled compared with nine treated patients (Fisher's exact probability test P = 0·44). The transfusion requirements of control patients (3·9±3·2 units) was not different from that of treated patients (5·7 ± 3·7 units): Mann Whitney U test, P = 0·06. In the treatment group there was no difference in the operation rate. Also, the number of probe applications between patients with further bleeding and those with no further bleeding was similar (11·6 ± 5·5 and 11·0 ± 5·75 respectively). Access with the probe was considered inadequate in 50 per cent of lesions, but this did not correlate with the incidence of rebleeding. Stigmata of recent haemorrhage were significant in predicting rebleeding (P = 0·0019 Fisher's exact probability test). Overall mortality rate of 3·2 per cent was low and was not influenced by electrocoagulation or presence of stigmata of recent haemorrhage. We have not shown that BICAP bipolar electrocoagulation reduces the incidence of rebleeding in upper gastrointestinal haemorrhage.
