What are the bleeding risks and management strategies for hemorrhoidectomy?

Hemorrhoidectomy Bleeding Risk and Management

Hemorrhoidectomy is classified as a low/moderate bleeding risk procedure with a 30-day major bleeding risk of 0-2%, not a high bleeding risk procedure. 1

Bleeding Risk Classification

• Hemorrhoidectomy is specifically categorized as a low/moderate bleeding risk procedure according to the International Society on Thrombosis and Haemostasis (ISTH) Guidance Statement 1
• The 30-day incidence of major bleeding for low/moderate risk procedures like hemorrhoidectomy is approximately 0.9% (95% CI: 0-1.3) 1
• In contrast, high bleeding risk procedures have a significantly higher 30-day major bleeding risk of >2% (approximately 2.48%, 95% CI: 0-3.4) 1

Perioperative Anticoagulation Management

• For patients on oral anticoagulants undergoing hemorrhoidectomy, the recommended approach is interruption of 2-3 drug half-lives preprocedure 1
• This allows for some residual anticoagulant effect (i.e., 3 days off for warfarin, 1 day off for DOACs) 1
• Therapeutic-dose anticoagulant resumption should occur within 1 day postprocedurally 1
• Patients on antithrombotic medications have approximately 2.3 times higher risk of postoperative bleeding events compared to those not on antithrombotics (5.92% vs. 2.66%) 2

Surgical Technique Considerations

• Conventional excisional hemorrhoidectomy (Milligan-Morgan or Ferguson techniques) is the most effective treatment overall for third-degree hemorrhoids, with recurrence rates of 2-10% 3
• Stapled hemorrhoidectomy may offer advantages of less postoperative pain, shorter operation time, and earlier return to normal activity, but has potential complications 4
• Complications after stapled hemorrhoidectomy occur in approximately 15% of patients, with immediate complications including severe pain (5.0%), bleeding (4.2%), and thrombosis (2.3%) 5
• Late bleeding from inflammatory polyps at the staple line has been reported in 11% of patients undergoing stapled hemorrhoidectomy 6

Specific Bleeding Management Strategies

• For thrombosed external hemorrhoids, surgical excision provides faster symptom resolution (3.9 days vs. 24 days) and lower recurrence rates (6.3% vs. 25.4%) compared to conservative management when performed within 72 hours of onset 1
• Simple incision and drainage of thrombosed hemorrhoids is not recommended due to higher incidence of bleeding and symptom relapse 1
• For bleeding complications after hemorrhoidectomy, management options include surgical intervention (24% of cases), Foley catheter insertion (15%), or epinephrine infiltration (2%) 5
• Approximately 6% of patients with significant post-hemorrhoidectomy bleeding may require blood transfusion 5

Prevention of Bleeding Complications

• Preoperative risk assessment should include evaluation of patient-specific factors (age, comorbidities, bleeding disorders) and procedure-specific factors 7
• Careful surgical technique with meticulous hemostasis is essential to minimize bleeding risk 8
• For patients with bleeding disorders, tranexamic acid is the preferred prophylactic option for minor surgeries 7
• Postoperative care should include appropriate bowel management to prevent constipation and straining, which can increase bleeding risk 3

Special Considerations

• Portal hypertension can cause varices of the anal canal, which are distinct from hemorrhoids and should not be treated with standard hemorrhoidal treatments 1
• Rectal variceal bleeding is best managed by addressing the underlying portal hypertension rather than hemorrhoid-specific interventions 1
• Anemia due to hemorrhoidal disease is rare (0.5 patients/100,000 population) but responds well to hemorrhoidectomy when present 1
