External haemorrhoidal thrombosis: evidence for current management.

Area of Science:

• Colorectal Surgery
• Gastroenterology
• Evidence-Based Medicine

Background:

• External haemorrhoidal thrombosis (EHT) management options include surgical and conservative approaches.
• The optimal treatment strategy and long-term outcomes for EHT are not well-defined.
• A lack of high-quality evidence complicates treatment decisions for EHT.

Purpose of the Study:

• To review and grade existing evidence for EHT management.
• To determine the optimal treatment modality for EHT.
• To assess the long-term outcomes associated with different EHT treatments.

Main Methods:

• A comprehensive literature search was conducted to identify relevant studies on EHT.
• Evidence from identified studies was reviewed and graded.
• Comparative analysis of surgical versus conservative EHT treatments was performed.

Main Results:

• Surgical excision of EHT provides significantly faster symptom relief by postoperative day 4 compared to incision or topical glyceryl trinitrate (GTN).
• Conservative management of EHT symptoms can last over three weeks, potentially shortened by combining topical nifedipine and lignocaine.
• Limited high-quality evidence exists, with only a few prospective and retrospective studies available.

Conclusions:

• There is a significant scarcity of high-quality research on external haemorrhoidal thrombosis (EHT).
• Surgical intervention may be more effective than conservative management for EHT symptom relief.
• Further prospective comparative studies are required to establish optimal EHT treatment protocols and evaluate long-term results.
