Laparoscopic coeliac axis decompression successfully treated Dunbar syndrome in a 31-year-old woman, with complete symptom resolution and return to normal eating within 48 hours post-surgery. According to Gram Research analysis, imaging confirmed the compressed blood vessel returned to normal size with no residual stenosis, and the patient was discharged home on postoperative day four. This minimally invasive surgical approach offers a faster recovery alternative to traditional open surgery for this rare condition.
Dunbar syndrome is a rare condition where a ligament in your abdomen squeezes a major blood vessel, causing severe stomach pain after eating. According to Gram Research analysis, doctors have successfully used a minimally invasive surgical technique called laparoscopic decompression to treat this condition. In a recent case, a 31-year-old woman with years of debilitating symptoms had the surgery and experienced complete relief within days. The procedure uses small incisions and cameras instead of major surgery, allowing patients to recover quickly and return to eating normally. This technical note demonstrates that laparoscopic surgery is a safe and effective treatment option for this previously difficult-to-treat condition.
Key Statistics
A 2026 case report published in Minimally Invasive Therapy & Allied Technologies documented successful laparoscopic coeliac axis decompression in a 31-year-old woman with Dunbar syndrome, with operative time of 90 minutes and complete symptom resolution by postoperative day two.
Two-week post-operative CT angiography in the Dunbar syndrome patient showed complete restoration of coeliac trunk calibre with no residual stenosis or extrinsic compression, confirming successful surgical decompression.
The patient with Dunbar syndrome treated via laparoscopic decompression was discharged home on postoperative day four with no complications and demonstrated normal blood flow patterns on two-month duplex ultrasonography follow-up.
The Quick Take
- What they studied: Whether a minimally invasive surgical technique can safely treat Dunbar syndrome, a rare condition where a ligament compresses a major blood vessel and causes severe stomach pain after eating.
- Who participated: One 31-year-old woman who had suffered from severe stomach pain, nausea, and vomiting after meals for a long time before undergoing the procedure.
- Key finding: The patient experienced complete symptom resolution after laparoscopic coeliac axis decompression, was able to eat solid food by day two post-surgery, and imaging confirmed the blood vessel compression was completely relieved.
- What it means for you: If you have Dunbar syndrome, this surgery offers a minimally invasive option that may provide relief with faster recovery than traditional open surgery. However, this is based on one case, so discuss with your doctor whether this approach is appropriate for your situation.
The Research Details
This is a technical case report describing a single patient’s surgical experience. The doctors performed laparoscopic coeliac axis decompression, which means they used a camera and small instruments inserted through tiny incisions to release the ligament compressing the blood vessel. Before surgery, imaging tests (CT angiography and ultrasound) confirmed the diagnosis by showing narrowing of the blood vessel. The surgical team carefully dissected tissue along the front of the aorta (the body’s main artery) to safely release the compressed vessel. After surgery, the patient was monitored closely, and imaging was repeated at two weeks and two months to confirm the vessel remained open and uncompressed.
This technical approach is important because Dunbar syndrome is rare and difficult to diagnose, and traditional open surgery requires large incisions and longer recovery. By demonstrating that minimally invasive laparoscopic surgery can successfully treat this condition, doctors now have evidence that patients may recover faster with less pain and complications. The detailed step-by-step description helps other surgeons learn and replicate this technique safely.
This is a single case report, which is the lowest level of research evidence. It shows that the procedure is possible and worked in one patient, but cannot prove it works for everyone with this condition. The strength of this report is the detailed documentation and follow-up imaging confirming success. Readers should understand this represents one surgeon’s experience with one patient, not a large study proving effectiveness across many patients.
What the Results Show
The patient underwent a 90-minute laparoscopic surgery to decompress the coeliac axis. The surgery went smoothly with no complications during the procedure. By the second day after surgery, the patient was able to eat solid food without pain, nausea, or vomiting—symptoms that had plagued her for years. She was discharged home on the fourth day after surgery, indicating a rapid recovery. Imaging performed two weeks after surgery showed that the blood vessel had returned to normal size with no remaining compression or narrowing. At the two-month follow-up ultrasound, the blood vessel showed normal blood flow patterns with no abnormalities.
The operative time of 90 minutes is reasonable for this complex vascular procedure. The uneventful postoperative course means the patient experienced no infections, bleeding, or other complications. The rapid return to normal diet and discharge within four days demonstrates the advantage of the minimally invasive approach compared to traditional open surgery, which typically requires longer hospitalization and recovery.
Dunbar syndrome has traditionally been treated with open surgery, which requires a large abdominal incision and longer recovery time. This case report adds to growing evidence that minimally invasive laparoscopic techniques can be adapted for complex vascular conditions. While previous case reports exist for laparoscopic treatment of this condition, this detailed technical note provides surgeons with a reproducible step-by-step approach, potentially making the procedure more accessible and safer when performed by trained surgeons.
This is a single case report involving one patient, so results cannot be generalized to all patients with Dunbar syndrome. Different patients may have different anatomy, severity of compression, or associated conditions that could affect outcomes. Long-term follow-up beyond two months is not provided, so durability of the repair over years is unknown. The patient’s age (31) and sex may not represent all patients with this condition. Success in one case does not guarantee success in all cases, and individual results will vary based on surgeon experience and patient factors.
The Bottom Line
Laparoscopic coeliac axis decompression appears to be a safe and effective treatment option for Dunbar syndrome when performed by experienced surgeons. Moderate confidence: This recommendation is based on successful outcomes in this case and growing evidence from similar reports, but larger studies are needed. Patients with Dunbar syndrome should discuss this minimally invasive option with a vascular surgeon experienced in laparoscopic techniques, as it may offer faster recovery than traditional open surgery.
This finding is most relevant to people with diagnosed Dunbar syndrome experiencing chronic postprandial (after-eating) abdominal pain, nausea, and vomiting. Vascular surgeons and general surgeons should be aware of this laparoscopic technique as an alternative to open surgery. Patients should not self-diagnose; Dunbar syndrome requires imaging confirmation by a doctor. People with occasional stomach pain after eating should not assume they have this rare condition without proper medical evaluation.
Based on this case, symptom relief may occur immediately after successful surgery, with the patient tolerating solid food within 48 hours. Hospital discharge typically occurs within 4 days. Imaging confirmation of vessel patency occurs at 2 weeks. Full functional recovery and return to normal activities may take several weeks. Individual timelines will vary based on overall health, surgical complications, and other factors.
Frequently Asked Questions
What is Dunbar syndrome and what causes the stomach pain?
Dunbar syndrome occurs when a ligament called the median arcuate ligament squeezes the coeliac artery, a major blood vessel supplying the stomach and intestines. This compression reduces blood flow to digestive organs, causing severe pain, nausea, and vomiting after eating. It’s a rare condition requiring surgical treatment.
How is laparoscopic surgery different from regular surgery for Dunbar syndrome?
Laparoscopic surgery uses small incisions and a camera instead of one large incision, allowing faster recovery and less pain. In this case, the patient ate solid food by day two and went home on day four, compared to weeks of recovery with traditional open surgery.
How long does it take to recover from laparoscopic coeliac axis decompression?
Based on this case report, patients may tolerate solid food within 48 hours and be discharged within 4 days. Full functional recovery typically takes several weeks. Individual recovery varies based on overall health and any complications.
Is laparoscopic surgery for Dunbar syndrome proven to work long-term?
This case report shows excellent short-term results with symptom relief and vessel patency confirmed at two months. However, long-term durability beyond two months is not yet documented. Larger studies are needed to establish long-term success rates across many patients.
What imaging tests confirm Dunbar syndrome before surgery?
CT angiography and colour duplex ultrasonography are used to confirm diagnosis by showing narrowing or compression of the coeliac artery. These same imaging tests are repeated after surgery to verify the vessel is decompressed and blood flow is restored.
Want to Apply This Research?
- Track daily postprandial (after-meal) abdominal pain using a 0-10 scale before surgery and weekly after surgery to objectively measure symptom improvement. Also log which foods trigger symptoms and meal tolerance progression.
- Users can use the app to document their dietary tolerance progression post-surgery, starting with liquids and soft foods, then advancing to solid foods as tolerated. This creates an objective record to share with their surgical team and helps identify any foods that cause symptom recurrence.
- Establish a long-term tracking system that monitors pain levels, food tolerance, and quality of life metrics monthly for the first year post-surgery, then quarterly thereafter. Set reminders for scheduled follow-up imaging appointments and vascular ultrasounds to ensure the vessel remains patent and uncompressed.
