Did something go wrong during your endometriosis surgery — and does the law recognise it?
Many people with endometriosis describe a long road before surgery — years of dismissed pain, misdiagnosis, and being told their symptoms were normal. When surgery finally happens, the expectation is relief. For some, what follows instead is new damage, unresolved disease, or complications that nobody warned them about. Understanding whether that outcome reflects a care failure — or simply a difficult condition — is what this article is about.
A common pattern — where care can break down in endometriosis surgery
Endometriosis surgery involves removing or destroying tissue that grows outside the uterus. Surgeons perform this through laparoscopy — a keyhole procedure using a small camera — or, in more complex cases, open surgery. The skill required varies enormously depending on how far the disease has spread.
Several distinct failure patterns appear in endometriosis surgical care. Each one can cause real harm. Recognising them helps you understand whether what happened to you fits a known pattern of substandard care.
Incomplete excision of disease
Excision means cutting out endometriosis tissue at its root. Ablation means burning the surface. Ablation is faster and simpler, but it leaves disease behind. A surgeon who chooses ablation when excision was clearly needed — or who fails to remove all visible disease during excision — may leave a patient with ongoing pain and the need for repeat surgery.
The Australian Commission on Safety and Quality in Health Care recognises that surgical technique and completeness of treatment are core components of safe surgical care.
Injury to surrounding organs
Endometriosis can attach to the bowel, bladder, ureters, and major blood vessels. Surgery in these areas carries real risk. But some injuries happen because the surgeon failed to identify the anatomy correctly, operated beyond their skill level, or did not refer the patient to a specialist with the right expertise. A bowel perforation or ureteral injury that goes unrecognised during surgery — and is not repaired promptly — can cause life-threatening complications.
Failure to refer to a specialist
Not every gynaecologist has the training to manage severe or deeply infiltrating endometriosis. A general gynaecologist who attempts complex surgery without the necessary skill — rather than referring the patient to an endometriosis specialist — may expose the patient to avoidable harm. Referral is part of the standard of care when a case exceeds a clinician’s competence.
Inadequate pre-operative assessment
Before surgery, a clinician should assess the extent of the disease using imaging, clinical examination, and patient history. Failing to identify bowel or bladder involvement before operating can mean the surgical team is unprepared for what they find. That lack of preparation can lead to incomplete treatment or unrecognised injury.
Poor post-operative monitoring
After endometriosis surgery, the clinical team should monitor the patient for signs of internal bleeding, infection, or organ injury. Discharging a patient too early, or dismissing post-operative pain as expected, can delay the detection of a serious complication. Early detection of a bowel injury, for example, can be the difference between a manageable repair and a life-threatening emergency.
When things start to go wrong — warning signs after endometriosis surgery
Some discomfort after laparoscopic surgery is normal. Shoulder tip pain from gas, mild bloating, and fatigue are common in the first few days. But certain symptoms after endometriosis surgery are not normal. They are warning signs that something may have gone wrong.
Warning signs that should have prompted urgent clinical action:
• Severe or worsening abdominal pain in the days after surgery
• Fever above 38°C that does not resolve
• Inability to pass urine, or blood in the urine
• Bowel symptoms including inability to pass wind or stool, or rectal bleeding
• Swelling, redness, or discharge at the incision site
• Feeling faint, dizzy, or experiencing a rapid heart rate
• Persistent pain that is worse than before the surgery
If you reported these symptoms and a clinician dismissed them, that dismissal may itself be a failure of care. The standard of care requires clinicians to take post-operative symptoms seriously and investigate promptly.
Mild shoulder or abdominal discomfort for 2–5 days
Light fatigue and bloating
Small amounts of vaginal spotting
Gradual improvement in pain over 1–2 weeks
Escalating pain that does not improve with medication
Fever, chills, or signs of infection
Urinary or bowel symptoms suggesting organ injury
Symptoms identical to or worse than before surgery

Understanding endometriosis surgery — what proper care looks like
Endometriosis is a condition where tissue similar to the lining of the uterus grows in other parts of the body — most commonly on the ovaries, fallopian tubes, and the tissue lining the pelvis. This tissue responds to hormonal cycles, causing inflammation, scarring, and pain. Surgery aims to remove or destroy this tissue to reduce symptoms and improve fertility outcomes.
Proper surgical care for endometriosis begins well before the operating theatre. A competent clinician takes a thorough history, orders appropriate imaging, and stages the disease — meaning they assess how widespread and severe it is. Staging guides the surgical plan and determines whether a specialist referral is needed.
What patients are typically told before surgery
Before endometriosis surgery, a surgeon should explain the procedure in detail. That explanation must include the risks — including the risk of injury to the bowel, bladder, or ureters — and the realistic chance that surgery will not eliminate all symptoms. Informed consent means the patient understands what the surgery involves, what could go wrong, and what the alternatives are.
A surgeon who does not explain these risks before operating has not obtained proper informed consent. That failure can itself form part of a negligence claim, separate from any surgical error that follows.
Key fact: Endometriosis affects approximately one in nine Australian women of reproductive age.
Key fact: On average, it takes 6.5 years from the onset of symptoms to receive a diagnosis in Australia.
Key fact: Deeply infiltrating endometriosis — where tissue penetrates more than 5mm below the surface — requires specialist surgical expertise that not all gynaecologists possess.
Key fact: Recurrence of symptoms after surgery does not automatically mean the surgery failed. But incomplete excision of visible disease may indicate a surgical error.
Why this matters legally
Duty of care is the legal obligation a clinician owes to their patient — a requirement to provide care that meets the standard of a competent professional in the same field. Every surgeon who operates on a patient with endometriosis owes that patient a duty of care.
Not every complication after endometriosis surgery means the surgeon did something wrong. Surgery on tissue that has adhered to the bowel or bladder carries genuine risk. A bowel injury during complex endometriosis surgery is not automatically negligence. The legal question is whether a competent surgeon, exercising reasonable skill and care, would have caused the same injury — or whether the injury resulted from a failure to meet the required standard.
Reasonable care in this context means: choosing the right surgical technique, operating within one’s competence, referring when the case exceeds that competence, obtaining proper informed consent, and monitoring the patient adequately after surgery. A failure in any of these areas may constitute a breach of duty. For a broader explanation of how medical negligence law works in NSW, see Reframe Legal — Medical Negligence.
A ureteral injury that occurred during surgery on deeply infiltrating endometriosis, where the surgeon identified it promptly and repaired it, and had warned the patient of this risk beforehand
A bowel perforation that the surgical team failed to recognise during the procedure, leading to peritonitis and emergency surgery — where no warning of this risk was given before the operation
This is a general educational framework only. Each case is assessed on its individual facts.
When endometriosis surgery may amount to medical negligence
The NSW Civil Liability Act 2002 sets the legal framework for medical negligence claims in this state. It requires a court to assess whether a clinician acted in a way that a significant body of competent professionals in the same field would regard as acceptable. If the answer is no, and that failure caused measurable harm, a claim may succeed.
Several specific scenarios in endometriosis surgical care may meet this threshold.
If a surgeon performed ablation on deeply infiltrating endometriosis — knowing excision was the appropriate technique — and the patient continued to suffer severe pain requiring further surgery, that choice may constitute a breach. If a general gynaecologist attempted surgery on stage four endometriosis without the specialist training to manage bowel or bladder involvement, and caused an organ injury as a result, the failure to refer may be the breach. If a surgeon did not warn a patient that the procedure might not resolve her symptoms, and she would have chosen a different treatment path had she known, the consent failure may support a claim.
Post-operative failures also matter. If a patient returned to hospital with signs of a bowel injury and the clinical team dismissed her symptoms for 48 hours before investigating, that delay may have worsened the outcome in a way that is legally significant.
When harm becomes long-term or permanent
For many people, the harm from a failed endometriosis surgery does not resolve in weeks. It reshapes their life over years.
Physically, an unrecognised bowel injury can lead to peritonitis — a dangerous infection of the abdominal cavity — requiring emergency surgery, a temporary stoma, and months of recovery. Ureteral damage can cause kidney dysfunction. Incomplete excision can mean ongoing pelvic pain, repeated surgeries, and in some cases, damage to fertility that cannot be reversed.
Psychological consequences
The psychological impact of surgical harm in endometriosis cases is often severe. Many patients already carry years of trauma from being dismissed before diagnosis. A surgical failure — particularly one that worsens their condition or removes their chance of having children — can cause significant anxiety, depression, and post-traumatic stress. These psychological consequences are legally recognised as part of the harm caused.
Financial consequences
Lost income during extended recovery, the cost of repeat surgeries, ongoing specialist appointments, pain management, and fertility treatment all accumulate. For some patients, the harm affects their capacity to work permanently. These financial losses form part of what a compensation claim can address.
What compensation can cover in endometriosis surgery cases
NSW law allows compensation for the full range of harm caused by medical negligence. That includes pain and suffering, loss of enjoyment of life, past and future medical expenses, lost income, and the cost of ongoing care or assistance.
| Level of harm | Typical compensation range |
|---|---|
| Moderate injury | $50,000–$150,000 |
| Serious injury | $150,000–$500,000 |
| Severe / life-changing injury | $500,000+ |
Each case is assessed on its own facts. These figures are general ranges only. A case involving a bowel perforation that required emergency surgery and caused permanent digestive changes will be assessed very differently from a case involving incomplete excision that required one further procedure.
Time limits apply in NSW. Generally, a person has three years from the date they knew — or ought reasonably to have known — that they suffered harm as a result of negligence. For some people, that date is not the surgery itself but a later point when they understood the connection between the surgery and their ongoing harm. Waiting too long can extinguish a valid claim.
Bringing it together — do the pieces fit?
Understanding whether your experience may involve a legal failure requires connecting three things: what happened to you, what should have happened, and whether the gap between those two things caused your harm.
Connecting these pieces is not something you need to do alone. A lawyer with experience in medical negligence can examine the clinical records, identify where the standard of care may have been breached, and explain whether your harm is legally connected to that breach. For more on how this process works, see Reframe Legal — How Medical Negligence Claims Work in NSW.
You don’t need certainty to understand your position
Most people who have experienced harm after endometriosis surgery carry significant self-doubt. They wonder whether they are overreacting. They worry that the complication was just bad luck. Many have already been told — by the same clinical team — that what happened was unavoidable.
Legal clarity does not require you to be certain that something went wrong. It requires an examination of the facts — the clinical records, the operative notes, the post-operative documentation — against the standard of care that applied at the time. That examination is what a medical negligence lawyer does. Your job is simply to describe what happened.
Informed consent is a separate but related issue. If your surgeon did not explain the risks of your procedure in a way that allowed you to make a genuinely informed decision, that failure may support a claim regardless of whether the surgery itself was technically performed correctly. For more on this, see Reframe Legal — Informed Consent and Medical Negligence.
If you have concerns about the conduct of a registered health practitioner, AHPRA — Australian Health Practitioner Regulation Agency handles complaints about registered health practitioners in Australia. A complaint to AHPRA is separate from a legal claim and does not affect your right to pursue compensation.
About the lawyer behind this article
Dr Rosemary Listing is a NSW medical negligence lawyer with a PhD focused on the legal dimensions of medical harm. Her academic and legal work examines how clinical failures translate into legal accountability — and how patients can understand their rights without needing to become experts in medicine or law.
Dr Listing has worked with clients whose harm arose from endometriosis surgery — including cases involving incomplete excision, unrecognised organ injury, inadequate informed consent, and failures in post-operative monitoring. She understands that these cases often sit against a backdrop of years of dismissed symptoms, which shapes how patients experience and process surgical harm.
In endometriosis cases, the harm frequently comes not from the disease itself but from the way clinicians managed it — or failed to. A surgeon who operates beyond their competence, or who chooses a less effective technique to save time, may cause harm that a referral or a different approach would have prevented.
Clients who approach Dr Listing are not typically looking to blame anyone. Most want to understand what happened and whether the care they received was reasonable. That question — whether the standard of care was met — is the one her work is designed to answer.
Dr Listing’s role is to assess the clinical facts against the legal standard, explain what the evidence shows, and help clients decide whether they want to pursue a formal claim. She does not pressure anyone toward a particular outcome.
