The first ever National Audit of Small Bowel Obstruction (NASBO) launched its findings at Birmingham University on Friday. Setting out 6 key recommendations for improving standard care, the results will be a vital resource for the development of NHS guidelines and future research work.

The full recommendations are:

  • Early CT scanning offers the best diagnostic & prognostic information, enabling surgeons to decide whether a patient can be managed without surgery or if they require an operation
  • Water soluble contrast agent should be embedded in clinical management – for both prognostic and therapeutic purposes
  • Nutritional support should be planned from the moment a diagnosis of SBO is made, and tailored to each individual patient’s needs and current nutritional status. Involvement of specialist nutritional services should be considered by surgeons for all patients.
  • Surgery should be recommended and carried out within 72 hours in patients whose obstruction does not resolve through use of non-surgical treatments.
  • Risk assessments should be carried out on all patients recommended for surgery, enabling those at high risk of complications or death to be admitted to critical care facilities.
  • There may be a benefit to applying ‘enhanced recovery’ strategies to patients managed both surgically and non-surgically

Small bowel obstruction, or SBO, is an enormous burden on NHS resources. It already accounts for up to 50% of emergency abdominal surgeries performed in the UK every year, with 13% of these patients dying within 3 months. NASBO’s findings showed average hospital stays of 10 days, with 13% of discharged patients re-admitted within 30 days.

People with SBO are very sick, unable to eat and in extreme pain. The single biggest risk factor is age, and with people living longer lives than ever before while NHS resources are stretched increasingly thinly, the challenge of treating them will only become more urgent.

Surgeons are desperate to find ways of treating SBO better because there are currently no standard protocols within the NHS.

Their biggest obstacle has been the fact that huge numbers of people are affected and many factors affect treatment, including levels of nutrition in the days leading up to hospital admission, old age and frailty, underlying medical conditions like Crohn’s disease, cancer, hernias and many more. The condition is extremely common and around 50% of patients admitted during the study had emergency surgery.

No one case is the same as the other, and evidence of what care strategies work better than others has been sparse, hence the need for a major national audit to provide a clearer look at the problem. BDRF granted funding for this hugely ambitious project in Spring 2016, and the results have enabled specialists to build a clearer picture of what is an enormous challenge.

Uptake was huge, with bowel specialists recognising the need to work together in tackling one of their most feared and complex conditions to treat. Surveying consultant surgeons around the UK, the team were able to get an idea of how individual specialists manage SBO and what variations there are between them. Overall, 131 hospitals signed up providing a network of 431 collaborators. These sites contributed data on the management of every patient over 16 years of age diagnosed with SBO at their hospital.   

In just 8 weeks the team logged data on the treatment journey of 2,434 patients compiling a uniquely broad set of data that can be the foundation of future work. While by no means definitive, the findings are of immense importance. They have enabled the team to identify ways to improve care right now, as well as posing questions that require more in-depth analysis in the form of new research projects.

Medical professionals present lauded the audit’s recommendations, which will have direct implications on their decision making in life or death situations. Factors like pre-surgery nutrition were identified as under-recognised, despite the findings showing a statistically significant improvement in outcomes for patients where nutrition was prioritised. A lack of awareness of nutritional scoring procedures was highlighted, with many surgeons saying this would change the way they regard the issue.

Other key factors were how quickly surgery is performed, early use of CT scanning and closer assessment of patients in the first 72 hours of care.

One of the study’s other defining features was that it was entirely designed and delivered by junior doctors, via surgical research collaboratives around the country.

Matt Lee, a member of the South Yorkshire Surgical Research Collaborative which spearheaded the project said What I really hope for NASBO is that it raises awareness of this really common condition and makes people focus on it a bit more, given that these patients are really, really sick – we just want to put a bit more focus on them”

Nicola Fearnhead, a consultant surgeon from Cambridge added “The beauty of NASBO is that we captured information on patients who do and don’t have surgery, and we now have high-quality information on what actually happens to these patients – what their pathways are, what the outcomes to their treatments are and where we can make differences for the future”.

BDRF’s CEO Peter Rowbottom also attended the day, remarking “NASBO is a real flagship project of BDRF, achieving our aims of saving and improving lives in the immediate future through a strategic approach to research. I would like to pay tribute to the research team and every collaborator on this project, whose dedication and willingness to do the hard yards of rigorously collecting and sifting through data on the management of thousands of patients will have real-world impacts and genuinely save lives. We couldn’t have achieved such a strong set of results without our close links to the membership of the ACPGBI – whose members form the bulk of collaborators and are on the front line of caring for these patients”.

SBO is a big issue for the NHS, and many people outside the medical profession would be surprised to learn that no standard guidelines exist for a condition that accounts for up to half of all emergency abdominal surgery in the UK. We all know how tight NHS budgets have become and it is absolutely crucial care is as effective and efficient as it possibly can be, preventing people being left languishing in hospital beds or readmitted within a short time after their treatment.

BDRF are extremely proud we have been involved in this project  – there is much more to do, but we now have a brilliant foundation with which to start writing standard care guidelines and conducting new projects to optimise treatment.
