Welcome to the official surgical guide for Endometriosis Surgical Specialists International (ESSI). The ESSI Patient Handbook: Your Guide to Surgery provides a transparent, evidence-based roadmap of our world-class surgical protocols, from initial mapping to long-term recovery. Authored by ESSI Founder Dr. Andrea Vidali alongside our specialized clinical team, this handbook translates decades of complex surgical expertise into a comprehensive clinical resource for patients.

Because endometriosis requires elite, multidisciplinary care, our surgical practice operates across state-of-the-art facilities in New York, New Jersey, Connecticut, Pennsylvania, Miami, and Southern California. Our renowned surgical team performs 600 to 700 complex endometriosis surgeries annually. This high surgical volume allows us to treat extrapelvic and deep infiltrating disease safely, bringing specialized colorectal, vascular, and general surgeons into the operating room so your disease is eradicated in a single operation.

Within this handbook, you will discover the foundational science driving our surgical outcomes:

• The Pelvic Overlap Spectrum (POSS): An advanced framework demonstrating how endometriosis operates as a systemic, inflammatory, and neurocentric disease.

• The ESSI Method: A detailed breakdown of our 100% robotic, multi-specialty approach. We utilize a neural-aware, vascular-aware, and immune-aware methodology to completely excise disease while preserving the delicate pelvic nerves.

• Fertility Preservation & Organ-Sparing Surgery: Deep insights into our tissue-sparing techniques. We rely on advanced argon beam coagulation for endometriomas rather than stripping the cyst wall, which statistically protects your Anti-Mullerian Hormone (AMH) levels and safeguards your reproductive future.

• Enhanced Recovery After Surgery (ERAS): Our targeted pain management and low-pressure pneumoperitoneum protocols, designed to significantly reduce surgical inflammation, shoulder pain, and the need for narcotic medications.

We believe that being fully informed is a fundamental component of exceptional medical care. Explore the complete text below to understand exactly how ESSI delivers definitive relief, protects your fertility, and sets the standard for modern endometriosis excision.
