Nd:YAG laser induces long-term remission in transfusion-dependent patients with watermelon stomach.
Watermelon stomach (gastric antral vascular ectasia) is a rare cause of gastric bleeding which can render patients transfusion-dependent. Laser therapy can be used to stop bleeding but the long-term success of this approach is not well described. We present a retrospective analysis of 24 consecutive transfusion-dependent patients who were treated in a national referral centre with Nd:YAG laser over an 18 year period. Laser therapy stopped all bleeding in 20 patients (83%) after a median of two sessions. Median follow up was 55 months (range 9-127). Patients remained transfusion free for a median of 16 months and a second course of treatment succeeded in all those who re-bled. One gastric perforation occurred early in the series and two patients developed pyloric stenosis which was successfully treated with balloon pyloric dilatation. Oestrogens were not used in these patients. Our experience shows that long-term remission from blood transfusion is seen in most patients treated with Nd:YAG laser. If bleeding recurs, further laser treatment is usually successful.
