Minimally invasive laparoscopic surgery has been the standard surgical approach for endometriosis for decades — and for many patients with accessible disease in straightforward anatomical locations, standard laparoscopy performed by an experienced surgeon provides excellent outcomes. But endometriosis does not always present in straightforward locations. Deep infiltrating endometriosis involving the uterosacral ligaments, the rectovaginal septum, the bladder wall, and structures in proximity to the ureter requires operating in some of the most anatomically complex and technically demanding areas of the pelvis — precisely where the limitations of standard laparoscopy become most relevant.
Robotic-assisted surgery addresses those limitations directly. The da Vinci surgical platform provides the surgeon with three-dimensional high-definition visualization, instruments with a greater range of motion than the human wrist, and a level of precision that is particularly valuable when operating adjacent to structures that cannot be compromised. For the right patient with the right disease, robotic assistance is not simply a technological preference — it is a meaningful clinical advantage that expands what is safely and thoroughly achievable with a minimally invasive approach.
This page explains what robotic-assisted endometriosis surgery involves, for whom it is most appropriate, how it differs from standard laparoscopy in practice, and what the experience of robotic-assisted excision at Lapeer Women’s Health looks like from consultation through recovery.
Robotic-assisted surgery is not indicated for every endometriosis case — but there are specific clinical scenarios where its technical advantages translate directly into better surgical outcomes. The following represent the situations where robotic assistance is most meaningfully beneficial.
Deep Infiltrating Endometriosis in the Posterior Pelvis
Deep infiltrating endometriosis (DIE) of the uterosacral ligaments and rectovaginal septum requires precise dissection in the narrow space between the uterus, vagina, and rectum — one of the most technically demanding areas in pelvic surgery. The robotic platform’s three-dimensional visualization provides depth perception that is not available with standard laparoscopy, and its wristed instruments allow the precise angles needed to excise disease in this space thoroughly while protecting the rectal wall. For women with rectovaginal endometriosis or deep posterior disease producing severe pain, dyspareunia, or rectal symptoms, robotic-assisted excision provides a technical foundation for thorough disease removal that standard laparoscopy may not match.
Endometriosis Adjacent to the Ureter
The ureter — the tube that carries urine from the kidney to the bladder — runs through the pelvic sidewall in close proximity to the uterosacral ligaments and the areas most commonly affected by deep infiltrating endometriosis. Ureteral injury is one of the most serious potential complications of pelvic surgery, and the ability to precisely identify and protect the ureter while excising adjacent endometriosis is critical. The robotic platform’s magnified three-dimensional visualization and fine instrument control allow the ureter to be clearly identified and kept out of the surgical field while endometriosis in its proximity is thoroughly removed.
Bladder Endometriosis
Endometriosis involving the bladder wall requires excision of the affected bladder segment — a procedure that demands precise control of bleeding, careful tissue handling, and the ability to repair the bladder accurately after excision. The robotic platform’s enhanced visualization and instrument articulation are particularly valuable in this setting, both for the excision itself and for any bladder repair that follows. For women with bladder endometriosis producing cyclical hematuria or significant bladder pain, robotic-assisted partial cystectomy with excision of the affected segment provides thorough treatment with precise repair.
Significant Adhesion Disease
Extensive adhesion formation — dense fibrous scar tissue binding pelvic organs together — is among the most technically demanding challenges in endometriosis surgery. Adhesiolysis in the context of significant disease requires careful identification of tissue planes, precise dissection to separate bound structures without injuring them, and the ability to work in a confined space with limited visualization. Robotic assistance improves the surgeon’s ability to navigate dense adhesion fields safely and thoroughly, reducing the risk of inadvertent organ injury while allowing more complete restoration of normal anatomy.
Complex Cases After Prior Surgery
Women who have had prior endometriosis surgery — particularly ablation surgery that did not produce adequate relief, or prior excision with residual or recurrent disease — often present with distorted anatomy from the combination of endometriosis and surgical scarring. Re-operative pelvic surgery in this setting is technically more demanding than primary surgery, and the robotic platform’s visualization and precision advantages are at their most clinically relevant in cases where anatomy has been altered by prior procedures.
The decision between standard laparoscopic and robotic-assisted excision is made based on the specific characteristics of your disease, your imaging, and the surgical assessment at your consultation. Not every endometriosis case requires robotic assistance — but for the cases that do, having access to a surgeon trained and credentialed in robotic-assisted gynecologic surgery is a meaningful advantage.
If you have been told that your endometriosis requires open abdominal surgery, or that minimally invasive treatment is not feasible for your degree of disease, a consultation to review your imaging and discuss your options with Dr. Andrei is a reasonable next step. Robotic-assisted surgery expands the range of endometriosis cases that can be addressed without open surgery.

Both standard laparoscopy and robotic-assisted surgery are minimally invasive approaches that use small abdominal incisions and provide the advantages of faster recovery and less surgical trauma compared to open surgery. The differences between them are operational and technical — and for certain endometriosis cases, those differences are clinically significant.
Visualization — Two-Dimensional vs. Three-Dimensional
Standard laparoscopy provides a high-definition two-dimensional image of the operative field on a monitor. The surgeon interprets depth from visual cues such as shadows and tissue movement rather than from true stereoscopic depth perception. Robotic-assisted surgery provides a true three-dimensional high-definition image through dual camera optics — giving the surgeon direct depth perception rather than inferred depth. In precise dissection in confined spaces — the posterior cul-de-sac, the rectovaginal septum, the area adjacent to the ureter — three-dimensional visualization translates directly into more accurate identification of tissue planes and disease margins.
Instrument Articulation — Fixed vs. Wristed
Standard laparoscopic instruments are rigid shafts that move in limited directions from the abdominal entry point. Their range of motion is constrained by the fulcrum effect of the abdominal wall — meaning that certain angles of approach to deeply positioned structures are difficult or impossible to achieve. Robotic instruments are wristed — they articulate at the tip in a manner analogous to the human wrist, providing a full range of motion at the instrument tip regardless of the entry angle. For deep infiltrating endometriosis in the posterior pelvis, this articulation allows precise approach angles that standard laparoscopic instruments cannot achieve without repositioning or accepting a suboptimal surgical angle.
Tremor Filtering and Precision
The robotic platform filters out the natural fine tremor present in any surgeon’s hand, translating movements at the console into smooth, precise instrument motions at the surgical site. This tremor filtering is most clinically relevant in the most delicate tissue planes — precisely the planes that matter most in deep infiltrating endometriosis excision adjacent to the rectum, ureter, and bladder.
What Is the Same Between the Two Approaches
Both standard laparoscopic and robotic-assisted endometriosis surgery involve small abdominal incisions, general anesthesia, direct visualization of the pelvis, and the same fundamental surgical steps of disease identification, excision, and adhesiolysis. Recovery experience and hospital stay are similar between the two approaches. The surgical goals are identical: the most complete removal of all visible and palpable endometriosis that is safely achievable. Robotic assistance changes the tools available to achieve those goals — it does not change the goals themselves.
Dr. Ramona D. Andrei, MD, PhD, FACOG is trained and credentialed in robotic-assisted gynecologic surgery and performs robotic endometriosis excision at her affiliated hospital facilities. Her approach uses robotic assistance selectively — for cases where its technical advantages meaningfully improve what is achievable — as part of a broader commitment to the most complete and minimally invasive endometriosis surgery possible for every patient.
Robotic-Assisted Excision for Complex Disease
Dr. Andrei performs robotic-assisted endometriosis excision for deep infiltrating disease, significant posterior pelvic involvement, cases requiring dissection adjacent to the ureter, bladder endometriosis, and complex re-operative cases. Standard laparoscopic excision is used for cases where robotic assistance does not provide additional technical advantage. The approach is matched to the disease — not to a preference for one platform over another.
Hospital Affiliations
Robotic endometriosis surgery is performed at McLaren Lapeer Region, Beaumont Hospital Royal Oak, and Crittenton Hospital — providing access to facilities equipped with the robotic surgical platform for patients from both the Lapeer and Rochester Hills service areas. Surgical facility selection is based on the specific procedure planned and the patient’s location preferences.
The Surgical Consultation
The consultation reviews your imaging, your symptom history, and your prior treatment in detail. The surgical approach — robotic-assisted, standard laparoscopic, or a combination — is discussed as part of the operative plan. Risks, benefits, expected outcomes, and recovery are explained specifically for your case. No recommendation is made without your full understanding of what is being proposed.
The experience of robotic-assisted endometriosis excision is broadly similar to standard laparoscopic excision from the patient’s perspective. The differences are in the operating room — in the precision and completeness of disease removal achievable with the robotic platform — rather than in the recovery experience.
The Surgical Consultation
The consultation involves a thorough review of your imaging and clinical history, discussion of the surgical approach most appropriate for your disease, explanation of risks and benefits specific to your case, and a complete opportunity to ask questions. If robotic assistance is recommended, the specific reasons — what aspects of your disease make it advantageous — are explained clearly. You will understand exactly what is planned and why before any surgical commitment is made.
The Day of Surgery
Robotic-assisted endometriosis excision is performed under general anesthesia at one of Dr. Andrei’s affiliated hospital facilities. Small incisions — typically three to four, each less than a centimeter — are made in the abdomen for the camera and robotic instrument arms. The procedure duration varies based on disease extent, typically ranging from one to three hours for most cases, and longer for the most complex presentations. Most patients are admitted for one night following surgery, with same-day discharge for shorter, less complex procedures.
Recovery
Recovery after robotic-assisted endometriosis excision is similar to standard laparoscopic recovery. Most patients are mobile within hours of surgery and experience their most significant discomfort in the first two to three days. Return to light activity typically occurs within one to two weeks. Full return to normal activities including exercise is usually achievable within two to four weeks for most cases. More extensive procedures involving deep infiltrating disease or significant adhesiolysis may require a somewhat longer recovery. Dr. Andrei provides individualized recovery guidance before discharge.
Outcomes After Robotic-Assisted Excision
The outcomes of robotic-assisted endometriosis excision reflect the outcomes of thorough excision surgery generally — meaningful improvement in pain, dyspareunia, cyclical bowel and bladder symptoms, and overall quality of life in most patients who undergo complete or near-complete disease removal. The specific value of robotic assistance is in the completeness of excision it enables in complex cases where standard laparoscopy would be technically limited — and in the preservation of vital structures that the platform’s precision makes possible in anatomically demanding locations.
Women with deep infiltrating endometriosis, significant posterior disease, or complex anatomical involvement are sometimes told that their condition is not suitable for minimally invasive treatment — that the complexity of their disease requires an open abdominal approach with a longer, more difficult recovery. In many cases, that assessment reflects the limits of standard laparoscopy rather than the limits of minimally invasive surgery as a category.
Robotic-assisted surgery extends the reach of minimally invasive technique into the most demanding locations in pelvic surgery. For the right patient with the right disease, it is the difference between a treatment that addresses the source of years of pain thoroughly — and one that does not. That difference is worth a surgical consultation to find out whether it applies to you.
