Background: Haemorrhagic radiation proctitis frequently presents as a problem in management. We analysed the technique of formalin dab in its management. Patients and Methods: Twenty patients presenting with haemorrhagic radiation proctitis and treated with formalin dab were prospectively analysed. Results: Twelve patients ceased to bleed following one session of formalin dab. Six patients needed more than one session to effect haemostasis. Two of three patients with torrential bleeding failed to respond to formalin dab and required surgical excision of the rectum. Conclusion: Formalin dab is a simple, effective and safe treatment modality in the management of chronic haemorrhagic radiation proctitis, and hence should be considered as the initial treatment modality for such a condition.
