Digestive and liver
Here, how often matters more than where.
Pancreatic and liver surgery are among the operations where the number of times a team performs the procedure is most closely tied to how patients do afterwards. That single fact should shape the whole decision.
Complex abdominal surgery is not one operation with one outcome. Pancreatic resection in particular is technically demanding, and centres that do many of them tend to recognise and manage complications earlier than centres that do a few. The same relationship holds, less steeply, for liver resection and for oesophageal surgery.
That isn’t an abstract claim about surgical skill in general. It’s measurable, specifically for pancreatic and liver resection. 16.3 percent versus 3.8 percent adjusted mortality for pancreatic resection at the lowest-volume hospitals compared with the highest-volume hospitals, the single largest volume-mortality gap of the 14 major operations studied, in an analysis of 2.5 million Medicare and national hospital-discharge records from 1994 to 1999. 12 percent versus 7.5 percent 90-day mortality for major liver resection at low-volume hospitals compared with hospitals performing more than 15 a year, across 4,263 US patients in the National Cancer Database from 2006 to 2015, a difference the study’s own authors attribute mainly to patient comorbidities rather than to hospital volume itself, and markedly smaller than the volume effect seen in pancreatic surgery.
Birkmeyer JD, Siewers AE, Finlayson EV, et al., "Hospital Volume and Surgical Mortality in the United States", New England Journal of Medicine, 2002;346(15):1128-1137 Checked 2026-09-18.
This study did not include liver resection among its 14 procedures, so this figure describes pancreatic resection specifically and should not be read across to liver surgery. The paywalled full text and tables were not accessible directly, only the verbatim published abstract, so the underlying five-tier volume breakdown behind these two endpoint figures is not independently confirmed here.
Diggs LP, et al., "Patient Comorbidities Drive High Mortality Rates Associated with Major Liver Resections Irrespective of Hospital Volume", The American Surgeon, 2021;87(7) Checked 2026-09-18.
One US registry study, and its own conclusion is that patient comorbidities, not hospital volume alone, are the larger driver of mortality risk for major liver resection; 78.5 percent of the patients studied were treated at low-volume centres.
So the useful question is not which country. It is how many of these operations the named surgeon and the named unit did last year, and what their approach is when something does not go to plan. We ask that in writing before anything else is decided.

Where an opinion earns its fee
Four decisions worth a second view.
Pancreatic surgery, and whether it is the right first step
For some pancreatic tumours, chemotherapy before surgery is now a recognised approach rather than an afterthought. Whether that applies to you depends on the position of the tumour and its relationship to nearby blood vessels, which is a radiology question as much as a surgical one.
A second read of the scans, by someone who is not going to be doing the operation, sometimes changes the sequence. It is one of the highest-value opinions in medicine, and one of the least often sought.
Liver resection, and whether enough liver remains
The liver regenerates, which is what makes resection possible at all. How much can safely be removed depends on the health of the remaining tissue, and that assessment differs between units. Some centres will operate where others would first shrink the tumour or grow the remaining lobe.
Colorectal cancer, and the order of treatment
Rectal cancer in particular often involves radiotherapy and chemotherapy around the surgery rather than surgery alone, and the sequencing affects both the outcome and whether a permanent stoma is likely. That is a conversation worth having twice.
Hernia repair after previous failed surgery
A first hernia repair is routine and almost never worth a flight. A large or repeatedly recurrent hernia, particularly after previous mesh, is a different operation requiring different expertise, and it is one of the cases where travelling to a high volume unit can make sense.
Where we would say no
A large part of this specialty should not be travelled for.
Saying so costs us work. It is also the reason our advice is worth anything.
Usually better done at home
- Straightforward gallbladder removal. Common, well done everywhere, and the travel cost swallows any saving
- First-time uncomplicated hernia repair, for the same reason
- Routine endoscopy and colonoscopy. If the wait at home is the problem, a local private scope is almost always cheaper than a flight
- Anything where a stoma is likely and you have no district nurse arrangement at home
- Acute presentations. Obstruction, bleeding and severe pain need treating where you are, today
Digestive surgery covers an enormous range, from twenty minute day cases to eight hour resections. Most of the volume sits at the simple end, and for that end the honest answer to whether you should fly is no.
What justifies travel is the complex end: cancer resections, revision work after a previous operation, and cases where the local unit does very few of your procedure a year.
If your case is in the first group, we will tell you in the free conversation and you will have spent nothing.
The part quotes leave out
Major abdominal surgery has a long tail.
A pancreatic or liver resection is not a procedure you fly home from in a few days. Recovery is measured in weeks, appetite and weight take months to settle, and a proportion of patients need a further intervention before they are through it.
That has three consequences for anyone considering travelling. The stay abroad is longer than for orthopaedic or cardiac work, so accommodation and time off work cost more. Fitness to fly home takes longer to reach and is a decision for the surgical team. And the nutritional follow-up, which affects how you do, has to be picked up by a dietitian where you live.
We build all three into the plan before you commit, because a quote that covers only the operation is describing a fraction of what you will spend and experience.
Questions
What people ask about digestive surgery abroad.
How do I find out how many operations a surgeon actually does?
You ask, in writing, and you ask for the figure for the specific procedure rather than for the department. A high volume surgeon will answer without hesitation. We put that question to every unit we approach on your behalf, and we send you the answer rather than a summary of it.
Is laparoscopic or robotic better for these operations?
For some, keyhole approaches reduce the recovery. For major pancreatic and liver resection the evidence is more mixed and depends heavily on the surgeon. The approach matters less than the experience of the person using it.
How long would I need to stay?
Considerably longer than for joint replacement. It depends on the operation and on your recovery, and any figure given before the case is assessed is a guess. We push for a realistic range in writing and we plan the accommodation around the upper end.
What if I need chemotherapy afterwards?
That is common in cancer cases, and it usually should be delivered where you live rather than abroad. Establishing before you travel that your local oncology service will take it on is part of the plan, not an afterthought.
Do you handle liver transplant here?
No. Transplant is governed separately and involves authorisation committee approval for foreign nationals under the Transplantation of Human Organs and Tissues Act. See the transplant page.
Find out whether your case is one that justifies travelling.
Thirty minutes, free. For a large part of this specialty the honest answer is to stay where you are, and we will say so.
