External hemorrhoidal thrombosis in the elderly patients: conservative and surgical management.

Background: External hemorrhoidal thrombosis is a common disease with an acute anal pain as the major symptom. It is astonishing the lack of studies which investigates the most effective treatment and there are not guidelines. Furthermore, nobody has ever evaluated this peculiar condition in an elderly population.

Methods: We have considered 87 patients aged >75 years who were visited and treated for this condition in our clinic, dividing them in three groups according the curative option chosen together with them after anamnesis and an interview: a conservative medical treatment (Group A), an immediate incision and evacuation of the thrombus (Group B) and the excision of hemorrhoid with the thrombus, with hemorrhoidectomy technique (Group C). The mean follow-up was 12.3 months. We analyzed immediate pain relief and time of remission of symptoms, bleeding, recurrences and major complications.

Results: The Group A presented a remission of symptoms in 11.8 days, Group B in 1.58 ad Group C in 7.8 days. The recurrence rate was very similar for the first two options (19.4% and 16.1%) and lower in the excision group (no recurrence during follow-up). Bleeding is the common adverse event observed with a high frequency in the immediate incision and evacuation of thrombus, less common in hemorrhoidectomy, that did not present major complication. Surgical option is often refused by elderly patient evaluating comorbidities in the fear of adverse events.

Conclusions: The surgical treatment for EHT in elderly is safe and effective, but not the most common choice for fear of complications. Medical treatment or immediate incision of thrombus can be preferred and well accepted by elderly even if followed by a higher rate of recurrences.
