Did your bowel obstruction after endometriosis surgery happen because of a care failure?
Pre-operative imaging and bowel assessment to identify endometriosis involving the bowel
Informed consent discussion including specific risk of bowel injury and obstruction
Careful surgical technique with colorectal surgeon involvement where bowel endometriosis is present
Post-operative monitoring for signs of bowel obstruction, including pain, nausea, and absent bowel sounds
Prompt investigation and treatment if obstruction signs appear — imaging, surgical review, intervention
If any of these steps was skipped or delayed, and a bowel obstruction caused you serious harm, the care you received may fall below the accepted standard.
Understanding bowel obstruction after endometriosis surgery: what normally happens
Endometriosis is a condition where tissue similar to the lining of the uterus grows outside it — often on the bowel, bladder, ovaries, or pelvic wall. Surgery to remove this tissue is called excision or ablation. For many women, it is the only effective treatment after years of pain.
When endometriosis grows on or near the bowel, surgery becomes significantly more complex. A bowel obstruction — a blockage that stops the normal movement of waste through the intestine — is a known risk of this surgery. Obstructions can happen because the surgeon accidentally injures the bowel wall, because scar tissue (called adhesions) forms after surgery and constricts the bowel, or because the bowel swells and stops functioning temporarily.
Most patients expect some pain and discomfort after surgery. What they do not expect is that their post-operative team will fail to recognise a developing obstruction, or that they will be discharged while something serious is already happening inside them. For more general information about bowel health and surgery, Healthdirect Australia provides accessible resources.
Key fact: Endometriosis affects approximately one in nine Australian women of reproductive age.
Key fact: Deep infiltrating endometriosis — the type most likely to involve the bowel — is frequently underdiagnosed for years before surgery.
Key fact: Bowel obstruction after endometriosis surgery can develop within days of the procedure or weeks later as adhesions form.
Key fact: A complete bowel obstruction is a medical emergency. Delayed treatment can cause bowel perforation, sepsis, and death.
When things start to go wrong
After endometriosis surgery, some discomfort is normal. Mild bloating, wind pain, and slow bowel return are expected in the first few days. But certain symptoms cross a line — and a competent clinical team must recognise that line.
The difficulty for patients is that the warning signs of a bowel obstruction can look, at first, like ordinary post-operative discomfort. Many women report that they raised concerns and were told it was normal. Some were discharged before the obstruction became obvious. Others were sent home with pain relief and told to wait.
Warning signs that should have prompted urgent investigation:
• Severe or worsening abdominal pain that does not settle with standard pain relief
• Abdominal distension — the belly becoming visibly swollen and hard
• No bowel movement and no passage of wind for more than 48–72 hours post-surgery
• Nausea and vomiting that persists or worsens after the first 24 hours
• Fever developing after surgery — a sign of possible infection or bowel compromise
• Absent or abnormal bowel sounds on clinical examination
• Rapid heart rate or low blood pressure — signs the body is under serious stress
A clinician who observes these signs must act. Waiting, reassuring, or discharging a patient with these symptoms is not acceptable care.
A common pattern — where care can break down
Bowel obstruction after endometriosis surgery does not always result from a single dramatic mistake. More often, harm builds through a series of smaller failures — each one compounding the last. The Australian Commission on Safety and Quality in Health Care has identified failure to recognise and respond to deteriorating patients as one of the most serious recurring problems in Australian hospitals.
Failure to plan for bowel involvement before surgery
A surgeon who operates on a patient with known deep endometriosis must assess whether the bowel is involved before the procedure begins. Pre-operative MRI or ultrasound can identify bowel endometriosis. Without this assessment, a surgeon may encounter bowel involvement unexpectedly during the operation — and be unprepared to manage it safely.
When a surgeon proceeds without adequate pre-operative planning, and the bowel is injured or inadequately managed as a result, that failure may constitute a breach of the standard of care.
Failure to involve a colorectal surgeon
Bowel endometriosis often requires a colorectal surgeon — a specialist in bowel surgery — to be present or available during the procedure. A gynaecologist operating alone on bowel endometriosis without this support may be working outside their competence. If bowel injury occurs in that context, the question becomes whether a competent surgeon would have recognised the need for specialist involvement.
Intraoperative bowel injury that went unrecognised
Sometimes a surgeon nicks or perforates the bowel during surgery and does not notice. The patient wakes up, appears to recover, and then deteriorates over the following days as bowel contents leak into the abdominal cavity. This is called a delayed bowel perforation. It is one of the most dangerous post-operative complications — and one of the most preventable if the surgical team checks carefully before closing.
Post-operative dismissal of symptoms
Many patients report that they told nurses or doctors about their worsening pain, their inability to pass wind, or their swelling abdomen — and nobody investigated further. A nurse who documents a concern but does not escalate it, or a doctor who reviews a patient briefly and discharges them without imaging, may have failed in their duty. The harm that follows is not the patient’s fault for not pushing harder. It is the system’s failure to respond.
Delayed diagnosis of obstruction after discharge
Some patients develop their obstruction after leaving hospital. They return to an emergency department with severe pain and are sometimes told it is constipation, gas, or a normal part of recovery. Hours or days can pass before someone orders an abdominal X-ray or CT scan. Every hour of delay in a complete bowel obstruction increases the risk of bowel death — a condition called ischaemia — and the need for major emergency surgery.
Why this matters legally
Every doctor, surgeon, and nurse who treats you owes you a duty of care — a legal obligation to provide treatment that meets the standard of a competent professional in their field. This duty exists whether you are in a public hospital or a private clinic.
Not every complication after endometriosis surgery is negligence. Bowel obstruction is a known risk of this type of surgery, and a risk that a competent surgeon can warn you about and manage — but cannot always prevent. The legal question is not whether the complication occurred. It is whether the clinical team met the standard of care before, during, and after the surgery.
If a surgeon failed to plan adequately, failed to involve the right specialists, caused an injury they did not recognise, or if the post-operative team dismissed clear warning signs — those failures may cross the line from complication into negligence. For a fuller explanation of how this works in NSW, see Reframe Legal — Medical Negligence.
A bowel obstruction caused by adhesion formation after technically competent surgery, where the post-operative team recognised and treated it promptly
A surgeon who caused an unrecognised bowel perforation during surgery, and a post-operative team that discharged the patient despite clear obstruction symptoms — leading to emergency surgery and permanent bowel damage
This is a general educational framework only. Each case is assessed on its individual facts.
When bowel obstruction after endometriosis surgery may amount to medical negligence
The NSW Civil Liability Act 2002 is the main law that governs medical negligence claims in this state. It sets out the standard a clinician must meet and the test for whether a failure caused harm. In plain terms, it asks: would a competent professional in the same field have acted differently?
Several specific scenarios may give rise to a negligence claim in this context.
If the surgeon did not warn you about bowel risk before surgery — a surgeon who knew or should have known that your endometriosis involved the bowel had a duty to tell you that bowel injury and obstruction were real risks. Without that information, you could not make a properly informed decision about whether to proceed.
If the surgeon caused a bowel injury and did not recognise it — an unrecognised bowel perforation during surgery is a serious failure. A competent surgeon checks the bowel before closing. Failure to do so, resulting in a delayed perforation and emergency surgery, may constitute negligence.
If the post-operative team dismissed your symptoms — a nurse or doctor who documented your worsening pain but took no further action, or who discharged you despite signs of obstruction, may have breached their duty. The harm that followed — emergency surgery, bowel resection, stoma formation — may be directly linked to that failure.
If the emergency department delayed diagnosis — a patient who presents to an emergency department with classic obstruction symptoms after recent abdominal surgery must receive prompt imaging. A delay of many hours before a CT scan, during which the bowel becomes ischaemic, may constitute a breach of the standard of care in that setting.
When harm becomes long-term or permanent
A bowel obstruction that receives prompt, competent treatment often resolves without permanent damage. But when diagnosis is delayed or treatment is inadequate, the consequences can be severe and lasting.
Physical consequences
A bowel that loses its blood supply becomes necrotic — the tissue dies. Surgeons must then remove that section of bowel. Depending on how much bowel is removed, a patient may need a stoma — a surgically created opening in the abdomen through which waste exits into a bag. Some stomas are temporary. Others are permanent. Either way, they change a person’s life profoundly.
Further surgeries to manage adhesions, repair damage, or reverse a stoma carry their own risks. Many patients enter a cycle of repeated hospitalisations and procedures that continues for years.
Psychological consequences
Living with a stoma, chronic abdominal pain, or the fear of another obstruction causes significant psychological harm. Many patients develop anxiety, depression, or post-traumatic stress after a serious bowel emergency. These are real, measurable harms — not side effects of surgery that patients simply have to accept.
Financial consequences
Extended hospital stays, repeated surgeries, stoma supplies, home nursing, and time away from work all carry financial costs. Women who were working before their surgery and cannot return — or who return to reduced capacity — face income losses that compound over years. These losses form a central part of any compensation claim.
Mild bloating and wind pain in the first 1–2 days
Gradual return of bowel function within 2–3 days
Manageable pain that improves with standard medication
Discharge when bowel sounds return and pain is controlled
Follow-up appointment scheduled before leaving hospital
Worsening abdominal pain that does not respond to medication
No bowel movement or wind passage beyond 72 hours
Visible abdominal distension and rigidity
Persistent vomiting beyond the first 24 hours
Fever, rapid heart rate, or signs of systemic illness
What compensation can cover in bowel obstruction cases
NSW law allows people who suffer harm through medical negligence to seek compensation for a range of losses. This includes pain and suffering, lost income (past and future), the cost of medical treatment and ongoing care, and the cost of assistance with daily tasks if the injury affects your ability to manage independently.
In bowel obstruction cases following endometriosis surgery, compensation claims often involve significant amounts — because the harm is frequently serious, the treatment is prolonged, and the impact on daily life is substantial.
| 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 permanent stoma, significant bowel resection, or inability to return to work would typically place a claim in the higher ranges.
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. Acting promptly preserves your options.
Bringing it together — do the pieces fit?
You may be reading this because something felt wrong — before, during, or after your surgery. Perhaps nobody warned you that your bowel was at risk. Perhaps you told the nurses about your pain and nothing happened. Perhaps you ended up in emergency surgery that you believe could have been avoided.
The legal question is not whether you suffered. It is whether the care you received fell below the standard that a competent clinician would have provided — and whether that failure caused your harm.
Understanding how negligence claims work in NSW can help you decide whether to take the next step. Reframe Legal — How Medical Negligence Claims Work in NSW explains the process in plain terms.
You don’t need certainty to understand your position
Most people who experienced a serious complication after surgery spend a long time wondering whether they are overreacting. They tell themselves that surgery is risky, that complications happen, that the doctors did their best. Some of that may be true. But uncertainty about whether something went wrong is not the same as certainty that it did not.
Legal clarity does not come from your gut feeling. It comes from examining the facts — the medical records, the clinical notes, the timing of events, and what a competent clinician would have done differently. You do not need to have that answer before you start asking questions.
If your surgery involved a consent discussion that did not cover bowel risk, understanding your rights around informed consent is an important starting point. Reframe Legal — Informed Consent and Medical Negligence explains what surgeons are legally required to tell you before operating.

About the lawyer behind this article
Dr Rosemary Listing is a NSW lawyer with a PhD focused on medical negligence. Her academic and legal work centres on the gap between the standard of care that patients are owed and the care they actually receive.
Dr Listing has worked on cases involving surgical complications in gynaecological and colorectal settings, including situations where bowel injury after endometriosis surgery went unrecognised or where post-operative deterioration was dismissed by clinical staff. She understands both the medical complexity of these cases and the legal framework that applies to them.
In her experience, the harm in these cases rarely comes from the surgery alone. More often, it comes from what happened — or did not happen — in the hours and days that followed. A team that monitors carefully and acts promptly can prevent a complication from becoming a catastrophe. When that team fails, the consequences fall entirely on the patient.
People who approach Dr Listing are not looking to punish anyone. Most want to understand what happened to them and whether the care they received was acceptable. That question deserves a careful, honest answer — and that is what she provides.
Dr Listing’s role is to assess whether the clinical team met the standard of care that the law requires. Where the evidence suggests they did not, she works to establish that clearly and to help her clients understand their legal position.
