Overview
Internal hemorrhoids are swollen veins in the lower rectum that can cause symptoms such as bleeding, pain, and prolapse. They are classified based on their degree of prolapse and severity of symptoms 3.Diagnosis
Visual inspection and digital rectal examination are initial steps 3.
Anoscopy or proctoscopy can confirm the presence and grade of hemorrhoids 3.
Grading system:
- Grade I: Hemorrhoids do not prolapse.
- Grade II: Prolapse during defecation but reduce spontaneously.
- Grade III: Require manual reduction after prolapse.
- Grade IV: Permanently prolapsed 3.Management
First-line treatments:
- High-fiber diet and increased fluid intake to soften stools 3.
- Topical agents like hydrocortisone creams for symptomatic relief 3.
Adjunctive treatments:
- Rubber band ligation for Grade II and III hemorrhoids 3.
- Sclerotherapy for smaller internal hemorrhoids 3.
- Infrared coagulation for less severe cases 3.Special Populations
Pregnancy: Increased pressure on pelvic veins may exacerbate hemorrhoids; conservative management is typically recommended 3.
Elderly: Comorbidities and decreased healing capacity may necessitate more conservative or minimally invasive approaches 3.
Comorbidities: Patients with cardiovascular disease should avoid anticoagulants unless absolutely necessary due to bleeding risk 3.Key Recommendations
Use a high-fiber diet and increased fluid intake as initial management to prevent constipation 3 (Evidence: Moderate).
Employ anoscopy or proctoscopy for definitive diagnosis and grading of internal hemorrhoids 3 (Evidence: Moderate).
Consider rubber band ligation for symptomatic Grade II and III internal hemorrhoids 3 (Evidence: Moderate).
Avoid aggressive interventions in elderly patients with multiple comorbidities due to increased risk of complications 3 (Evidence: Expert opinion).References
