At WALS 2025, this comprehensive educational session explores the changing landscape of minimally invasive surgery for endometriosis and adenomyosis, with particular attention to advanced laparoscopic techniques, individualized treatment strategies, anatomical precision, and fertility-preserving considerations. Both conditions can produce substantial symptoms and may coexist with infertility, chronic pelvic pain, abnormal uterine bleeding, and other gynecological problems. The development of minimally invasive technologies has provided surgeons with increasingly sophisticated tools for evaluating and treating appropriately selected patients.

Endometriosis remains a complex surgical condition because the disease can occur in multiple pelvic locations and may infiltrate or adhere to surrounding organs. Superficial peritoneal disease, ovarian endometriomas, and deep infiltrating endometriosis may require different surgical strategies. Deep disease can involve the rectovaginal region, bowel, bladder, ureters, pelvic sidewalls, and other critical anatomical areas. Consequently, successful surgery requires detailed knowledge of pelvic anatomy, appropriate preoperative evaluation, careful identification of disease, and an individualized operative plan.

Laparoscopy provides surgeons with magnified visualization of the pelvic cavity and can facilitate detailed assessment of endometriotic lesions and their anatomical relationships. Depending on the indication, minimally invasive procedures may include excision or treatment of endometriotic lesions, management of ovarian endometriomas, adhesiolysis, and complex pelvic dissection. In advanced cases, multidisciplinary surgical planning may be required when disease involves bowel, urinary tract structures, or other organs. Current guidance emphasizes interdisciplinary care for patients with suspected or confirmed endometriosis.

The development of robot-assisted surgery has added another technological option for selected complex cases. Robotic systems can provide three-dimensional visualization, articulated instruments, and enhanced dexterity, which may be useful during technically demanding pelvic dissections. However, the selection between conventional laparoscopy, robotic surgery, open surgery, or other approaches depends on the individual patient, disease characteristics, available expertise, resources, and clinical indication.

Adenomyosis presents a different surgical challenge because the disease affects the myometrium, rather than being confined to a clearly defined external lesion. It may occur in focal or diffuse forms, and the absence of a clear boundary between diseased and healthy uterine tissue can make complete excision difficult. For patients requiring surgical management and wishing to preserve the uterus, conservative procedures such as adenomyomectomy may be considered in selected circumstances. Laparoscopic and robotic approaches have been described for uterine-sparing surgery, although patient selection and surgical expertise remain important.

The presentation also emphasizes the importance of preoperative diagnosis and imaging. Pelvic ultrasound and MRI can provide important information regarding adenomyosis and can assist clinicians in understanding the location and extent of disease. Detailed imaging may help determine whether disease is focal or diffuse and can contribute to decisions regarding medical treatment, conservative surgery, or other interventions. Treatment planning should also consider symptoms, uterine size, reproductive objectives, previous treatment, and patient preferences.

One of the major advances in modern management is the increasing consideration of uterine and fertility preservation. Traditional definitive treatment for adenomyosis has included hysterectomy, but conservative treatment options have developed as the desire to preserve the uterus has increased. These approaches may include conservative surgery and selected image-guided procedures. Evidence for different techniques continues to evolve, and fertility-related outcomes require careful consideration when counseling patients who wish to conceive.

Minimally invasive management can also involve technologies beyond conventional laparoscopy. Depending on disease characteristics and local expertise, selected patients with adenomyosis may be considered for procedures such as high-intensity focused ultrasound, uterine artery embolization, radiofrequency ablation, or microwave ablation. These interventions are not interchangeable and may have different indications, evidence bases, availability, and implications for future fertility. Therefore, treatment decisions should be individualized and made after appropriate clinical evaluation.

The concept of precision surgery is particularly important in advanced endometriosis. Surgeons must identify disease while protecting normal anatomical structures, including the ureters, bladder, bowel, pelvic vessels, nerves, ovaries, and reproductive organs. Nerve-sparing principles and careful tissue handling have received increasing attention because surgical treatment should address disease while minimizing avoidable functional complications. Modern minimally invasive surgery therefore combines technological advances with detailed anatomical knowledge and meticulous surgical technique.

Another key message is that surgery should not be considered in isolation. Medical treatment, hormonal therapy, fertility treatment, pain management, postoperative follow-up, and lifestyle or supportive care may all have roles depending on the patient's circumstances. For adenomyosis, hormonal treatments are commonly used for symptom control, while surgical or interventional procedures may be considered when conservative medical management is insufficient or unsuitable.

This WALS 2025 educational session therefore highlights the continuing transformation of gynecological surgery through minimally invasive technology. The combination of advanced laparoscopy, robotic techniques, improved imaging, conservative surgical strategies, and multidisciplinary care is helping clinicians develop more individualized approaches for patients with endometriosis and adenomyosis.

The topic is particularly valuable for gynecologists, laparoscopic surgeons, reproductive medicine specialists, gynecological surgeons, and doctors pursuing advanced minimally invasive surgical training. By understanding the anatomical complexity of endometriosis and adenomyosis and the available minimally invasive approaches, clinicians can better appreciate the importance of careful diagnosis, appropriate patient selection, precise surgical planning, fertility considerations, and long-term follow-up.

The overall focus of this WALS 2025 presentation is not simply on performing minimally invasive procedures, but on using modern surgical technology thoughtfully to address complex gynecological disease. Advances in laparoscopic and robotic surgery continue to create new possibilities, while ongoing research is needed to establish the comparative effectiveness, long-term outcomes, recurrence rates, safety, and fertility implications of emerging techniques.
