  • Title: Per-endoscopic bipolar diathermy coagulation of visible vessels using a 3.2 mm probe--a randomised clinical trial.
    Author: Brearley S, Hawker PC, Dykes PW, Keighley MR.
    Journal: Endoscopy; 1987 Jul; 19(4):160-3. PubMed ID: 3304988.
    Abstract:
    Forty-four patients who had bled from peptic ulcers and whose ulcers showed stigmata of haemorrhage (bleeding, visible vessel or adherent clot) entered a trial of treatment with a 3.2 mm bipolar diathermy probe. Two patients had spurting haemorrhage when endoscoped and both were treated with the probe, control being obtained in one. The remaining patients were randomised to treatment or control groups. One patient who was treated was withdrawn because the ulcer proved to be malignant. Six of 20 treated patients rebled compared with 8 of 21 controls (relative risk 0.79; 90% CI 0.26-1.97). The operation rate, transfusion requirement and hospital stay were similar in the two groups. One perforation occurred in the treatment group. Per-endoscopic bipolar diathermy treatment confers little benefit in bleeding peptic ulcer disease.
