Endometriosis

Overview

A substantial component of Dr. Kruger's clinical practice is dedicated to the comprehensive surgical management of endometriosis. Endometriosis is a chronic, heterogeneous condition characterized by variable disease distribution, symptom severity, and impact on quality of life and fertility. Management requires an individualized, evidence-based approach, with surgery forming a key component of care for appropriately selected patients.

What is Endometriosis?

Endometriosis occurs when tissue similar to the lining of the uterus (endometrium) grows outside the uterus. This tissue responds to hormonal changes during the menstrual cycle, leading to inflammation, scarring, and adhesions. Endometriosis most commonly affects the pelvis, including the ovaries, peritoneum, uterosacral ligaments, and the space between the uterus and rectum.

Symptoms

• Chronic pelvic pain, often worsening during menstruation
• Painful intercourse (dyspareunia)
• Heavy or irregular menstrual bleeding
• Pain with bowel movements or urination, particularly during menstruation
• Infertility
• Fatigue and general malaise

Role of Surgery in Endometriosis Care

While medical therapy plays an important role in symptom suppression, surgery remains the definitive modality for diagnosis and anatomical disease eradication. Surgical intervention is most often considered in patients with:

• Persistent symptoms despite optimized medical therapy
• Intolerance or contraindications to hormonal treatment
• Suspected deep infiltrating disease
• Fertility preservation or restoration as a priority

Laparoscopy is the gold standard surgical approach, allowing accurate disease mapping, histologic confirmation, and definitive treatment within a minimally invasive framework.

Surgical Techniques

Excision of Endometriosis

Contemporary endometriosis surgery prioritizes complete excision of disease, rather than ablation, wherever technically feasible. Excision allows for:

• Removal of implants at their full depth of infiltration
• Histopathologic confirmation of disease
• Improved long-term pain control and reduced recurrence rates

Disease may involve the peritoneum, ovaries, uterosacral ligaments, rectovaginal septum, bladder, ureters, or bowel. Surgical complexity is dictated by disease location and depth.

Management of Deep Infiltrating Endometriosis (DIE)

Deep endometriosis may affect pelvic nerves, the urinary tract, or the gastrointestinal system and often presents with complex pain syndromes or organ-specific symptoms. Surgical management may include:

• Ureterolysis
• Bladder dissection
• Rectovaginal or bowel shaving
• Segmental bowel resection in selected cases

Ovarian Endometriomas

Cystectomy using tissue-sparing techniques is generally preferred, with careful attention to minimizing thermal and mechanical injury to normal ovarian tissue, particularly in patients with reproductive goals.

Hysterectomy in Endometriosis

In selected patients who have completed childbearing and have refractory symptoms, hysterectomy may be considered. Importantly, hysterectomy alone does not treat extra-uterine endometriosis — complete excision of all endometriotic disease remains essential regardless of whether the uterus is removed.

Preoperative Evaluation

• Detailed symptom assessment including pain phenotype and organ-specific symptoms
• Review of prior medical and surgical treatments
• Targeted imaging (ultrasound and/or MRI) for suspected deep disease
• Consideration of fertility goals and long-term management planning

Integration with Medical Therapy

Surgery is integrated into a longitudinal care model. Post-operative hormonal suppression is frequently recommended to reduce recurrence risk, particularly in patients not actively pursuing pregnancy. Adjunctive therapies, including pelvic floor physiotherapy and pain-focused interventions, are incorporated as needed.

Outcomes

Endometriosis surgery is most effective when:

• Guided by realistic expectations and shared decision-making
• Performed by surgeons with advanced training in minimally invasive surgery
• Embedded within a multidisciplinary care framework

The primary objectives are durable symptom relief, restoration of pelvic anatomy, preservation of organ function, and improvement in overall quality of life.
