Introduction

External hemorrhoids occur distal to the dentate line and develop as a result of distention and swelling of the external hemorrhoidal venous system. Engorgement of a hemorrhoidal vessel with acute swelling may allow blood to pool and, subsequently, clot; this leads to the acutely thrombosed external hemorrhoid (TEH), a bluish-purplish discoloration often accompanied by severe incapacitating pain. Although TEH is a common problem, it remains a poorly studied topic. Reported risk factors for TEH include a recent bout of constipation1,2 and traumatic vaginal delivery.3,4

Although conservative nonsurgical treatment (stool softeners, increased dietary fiber, increased fluid intake, warm baths, analgesia) ultimately result in resolution of symptoms for most patients, surgical excision of the TEH may often be the best treatment.5,6 In one retrospective study,7 surgical treatment resulted in much faster symptom resolution (3.9 d vs 24 d) as well as lower frequency of recurrence (6.3% vs 25.4%) in the study population. Another study8 demonstrated that, compared with simple incision or topically applied 0.2% glycerin trinitrate ointment, TEH excision improved recurrence rates, symptoms, and residual skin tags at 1-year follow-up.9

Newer conservative treatments such as topical nifedipine show promise over traditional conservative treatments such as lidocaine ointment;10 however, they have not yet been shown to decrease time to symptom resolution or frequency of recurrence as compared to surgical excision.

Surgical excision of the acutely thrombosed external hemorrhoid is within the purview of an office-based or emergency practitioner.

Indications

Acute pain and thrombosis of an external hemorrhoid within 48-72 hours of onset is an indication for excision.

Contraindications

Absolute contraindications to thrombosed external hemorrhoid excision in the emergency department include the following:

  • Any concern that the lesion may not be a thrombosed external hemorrhoid (including a painless rectal mass, since thrombosed external hemorrhoids are painful)
  • Grade IV internal hemorrhoid associated with a thrombosed external hemorrhoid
  • Known severe coagulopathy
  • Hemodynamic instability
Relative contraindications to emergency department excision of thrombosed external hemorrhoid include the following:
