The pelvis is one of the most anatomically intricate regions encountered by surgeons, and Dr. Shailesh Puntambekar's presentation at WALS 2025 explored how minimally invasive surgery has changed the way pelvic anatomy is understood and applied in clinical practice. His discussion emphasized that the major pelvic organs may be familiar to every surgeon, but the detailed relationships between fascial planes, potential spaces, vessels, ureters, nerves, and surrounding tissues continue to provide new opportunities for improving surgical precision.

The development of laparoscopic and robotic surgery has provided surgeons with a different visual perspective of the pelvis. Instead of viewing anatomy primarily through an open operative field or conventional anatomical dissection, minimally invasive surgery offers magnified visualization of living tissue. This can reveal subtle differences in tissue planes and anatomical structures and allows surgeons to progressively identify important landmarks during dissection.

This change in perspective is particularly significant in complex pelvic surgery. The pelvis contains multiple structures with limited physical separation. The urinary tract, reproductive organs, gastrointestinal tract, blood vessels, lymphatic structures, pelvic fascia, and nerves can be located within close proximity. Consequently, understanding their relationships is essential when performing procedures that require deep pelvic dissection.

Dr. Puntambekar has extensive experience in laparoscopic pelvic surgery and gynecologic oncology, and his contributions include the laparoscopic radical hysterectomy approach known as the “Pune Technique.” This work demonstrates the importance of detailed pelvic anatomy when performing surgery for cervical cancer and other complex gynecologic conditions.

One of the most valuable aspects of evolving pelvic anatomy is the increasing recognition of surgical spaces and anatomical planes. The paravesical and pararectal spaces, for example, can provide important orientation during pelvic procedures. Similarly, the rectovaginal plane and other fascial planes can guide dissection when appropriately identified. Knowledge of these spaces allows surgeons to think beyond individual organs and understand the pelvis as a connected three-dimensional anatomical environment.

The ureter and pelvic vessels are particularly important structures during gynecologic surgery. Their location relative to the uterus, cervix, uterine vessels, adnexa, and pelvic sidewall must be understood before and during dissection. A surgeon who recognizes these relationships can plan the operation around established anatomical landmarks rather than relying solely on visual identification of individual structures.

Nerve anatomy is another major component of modern pelvic surgery. Pelvic autonomic nerves contribute to bladder, bowel, and sexual function. When surgery involves deep pelvic dissection, understanding their location and relationship with surrounding fascia is essential. This has contributed to the development of nerve-sparing approaches in selected procedures, where preservation of function is considered alongside the primary surgical objective. Dr. Puntambekar's work in nerve-sparing laparoscopic surgery for deep infiltrating endometriosis illustrates this principle.

The concept of functional anatomy is therefore becoming increasingly important. Surgeons must not only know where a structure is located but also understand what function may be affected if that structure or its surrounding tissue is disrupted. This approach encourages meticulous dissection and careful consideration of tissue preservation wherever clinically appropriate.

Another important subject is the pelvic diaphragm and endopelvic fascia. These structures form essential components of the pelvic support system and define important anatomical boundaries. During extensive pelvic surgery, recognizing these boundaries helps surgeons understand the depth and extent of dissection. Dr. Puntambekar's anatomical work has emphasized the importance of these structures in complex pelvic procedures.

Modern pelvic surgery also benefits from improved preoperative imaging and surgical planning. Imaging can help surgeons understand disease distribution, anatomical variations, and the relationship of pathology to surrounding organs. When combined with detailed operative anatomy, this information can contribute to more structured surgical planning.

However, technology should not be viewed as a substitute for anatomical knowledge. A high-definition camera can magnify an anatomical structure, but the surgeon must still correctly identify that structure and understand its significance. This is why advanced laparoscopic training increasingly emphasizes surgical anatomy alongside instrument skills.

For trainees, pelvic anatomy can initially appear difficult because many structures become visible only after specific tissue planes have been opened. A structured approach—identifying landmarks, following fascial planes, understanding vascular pathways, and recognizing nerve locations—can make complex anatomy easier to interpret. Repeated exposure to laparoscopic anatomy can gradually build the three-dimensional mental model required for advanced pelvic surgery.

Dr. Puntambekar's work also demonstrates the relationship between anatomical understanding and surgical innovation. His experience in minimally invasive pelvic procedures and gynecologic oncology reflects how anatomical knowledge can contribute to the development and refinement of surgical techniques. His contributions to laparoscopic pelvic surgery and uterine transplantation further illustrate the importance of understanding pelvic vascular and organ anatomy in complex procedures.

The discussion at WALS 2025 is therefore relevant far beyond a single surgical procedure. It presents pelvic anatomy as a continuously developing field in which improved visualization, minimally invasive techniques, anatomical research, and surgical experience continually influence one another.

For gynecologists, gynecologic oncologists, general surgeons working in the pelvis, urologists, residents, fellows, and minimal access surgery trainees, this perspective provides an opportunity to revisit familiar anatomy from a modern surgical viewpoint. The ability to recognize tissue planes, understand pelvic spaces, protect important structures, and adapt the surgical approach to individual anatomy is central to advanced pelvic surgery.

Ultimately, the evolution of pelvic anatomy is not about changing the anatomy itself—it is about improving our understanding of it. Laparoscopy and robotic surgery have provided new ways to visualize and interpret the complex relationships within the pelvis. Dr. Shailesh Puntambekar's WALS 2025 presentation highlights how this deeper understanding can inform precise dissection, nerve preservation, oncologic surgery, and minimally invasive surgical education.

As minimally invasive surgery continues to develop, detailed knowledge of pelvic anatomy will remain one of the most important foundations of safe and precise surgery. WALS 2025 brought together international experts to discuss such advances, and Dr. Puntambekar's insights provide an important educational contribution to the continuing evolution of laparoscopic pelvic surgery.
