Bleeding hemorrhoids — Clinical Guidelines

Overview

Abnormal uterine bleeding (AUB) refers to uterine bleeding that deviates from normal menstrual patterns, affecting up to 30% of reproductive-age women at some point in their lives 5. It encompasses various conditions requiring careful evaluation and management to address underlying causes and improve quality of life 7.

Diagnosis

Clinical History: Comprehensive assessment including menstrual history, duration, and pattern of bleeding 7.

Physical Examination: Pelvic examination to assess for structural abnormalities 7.

Laboratory Tests: Hemoglobin levels, coagulation profile, especially in patients on anticoagulants 6 8.

Imaging: Transvaginal ultrasound to evaluate uterine anatomy and endometrial thickness 15.

Sonohysterography: Saline infusion sonohysterography can be useful in evaluating intrauterine pathology 15.

Hysteroscopy: Considered for definitive diagnosis and treatment of intrauterine lesions 14.

Management

First-Line Treatments:

- Hormonal Therapy: Oral contraceptives, levonorgestrel intrauterine system (LNG-IUS) for both contraception and bleeding control 10. - Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): For reducing menstrual bleeding 10.

Adjunctive Treatments:

- Iron Supplementation: For anemia associated with heavy bleeding 5. - Surgical Interventions: Uterine artery embolization (UAE) for severe, refractory cases 2. - Hysteroscopic Procedures: For removal of polyps or fibroids 14.

Special Populations

Pregnancy: Not directly addressed in abstracts; AUB in pregnancy requires distinct evaluation and management 5.

Anticoagulant Therapy: Heavy and irregular bleeding common; careful monitoring and dose adjustment needed 6 8.

Elderly: Considerations for comorbidities and treatment tolerance similar to general population, with focus on minimizing bleeding complications 8.

Key Recommendations

Comprehensive Clinical History and Physical Examination are essential for diagnosing AUB (Evidence: Strong 7).

Utilize Transvaginal Ultrasound and Sonohysterography for evaluating intrauterine pathology (Evidence: Moderate 15).

Consider Hormonal Therapies such as LNG-IUS for both contraception and bleeding control in appropriate patients (Evidence: Moderate 10).

Manage Patients on Anticoagulants with Careful Monitoring of bleeding episodes (Evidence: Expert opinion 6 8).

Evaluate and Treat Underlying Causes through appropriate diagnostic procedures like hysteroscopy when indicated (Evidence: Moderate 14).
