How the aneurysm is accessed is very important as it determines the result of the surgery. A 70-year-old man with a large coronary aneurysm (40 mm in diameter) in the LMT underwent surgery to prevent its rupture; however, there was severe adhesion. Initially, dissection of the ascending aorta or the pulmonary artery seemed necessary to access the aneurysm; however, the process was possible with limited dissection between the ascending aorta and the pulmonary artery, and we succeeded in firmly closing the LMT site of entry.

A 38-year-old man presented with a 2-month history of pain and stiffness in the bilateral wrist. The pain in right wrist was disabling and severe enough to restrict the daily life activities. After the evaluation of clinical and radiological features, the patient was diagnosed with Kienböck’s disease Lichtman stage IIIB in the right wrist and stage IIIA in the left wrist. Routine laboratory investigations revealed a serum uric acid 9.27 mg/dL. Lunate excision and scaphocapitate fusion were done in the right wrist after discussing with the patient. The histopathological examinations of tophi in synovial tissue were negatively birefringent under polarised light microscopy. It confirmed the diagnoses of gout. Febuxostat was started postoperatively. The patient returned to work at the end of 5 months. There was no recurrence of symptoms and radiological signs of arthritis at the end of 1 year.

<![CDATA[Aortobronchial fistula and Listeria endograft infection after repeated T/EVAR: a rare combination]]>

Here we present a rare combination of aortobronchial fistula and Listeria endograft infection after repeat endovascular aortic repair. Device retention, debridement and negative pressure wound therapy, in combination with suppressive antimicrobial therapy, led to satisfactory control of infection until the patient died due to another complication. The combination of an aortobronchial fistula and Listeria endograft infection has never been described before. This present case should encourage and show clinicians the importance of an interdisciplinary approach in highly difficult clinical courses.

<![CDATA[Surgical excision of post-traumatic myositis ossificans of the adductor longus in a football player]]>

A football player was diagnosed with myositis ossificans of his right adductor longus muscle after an acute injury. Conservative treatment failed and 1 year after the initial trauma the patient underwent surgical excision of a large ossification. Seven months postoperatively, the patient was fully recovered and returned to his preinjury activity levels. We present our approach to this case and discuss our considerations, referring to background information about this rare disease.

<![CDATA[Multidisciplinary approach to improve the quality of below-knee plaster casting]]>


In our trauma unit, we noted a high rate of incorrectly applied below-knee casts for ankle fractures, in some cases requiring reapplication. This caused significant discomfort and inconvenience for patients and additional burden on plaster-room services. Our aim was to improve the quality of plaster casts and reduce the proportion that needed to be reapplied.


Our criteria for plaster cast quality were based on the British Orthopaedic Association Casting Standards (2015) and included neutral (plantargrade) ankle position, adequacy of fracture reduction and rate of cast reapplication. Baseline data collection was performed over a 2-month period by two independent reviewers.


After distributing findings and presenting to relevant departments, practical casting sessions with orthopaedic technicians were arranged for the multidisciplinary team responsible for casting. This was later supplemented by new casting guidelines in clinical areas and available online. Postintervention data collection was performed over two separate cycles to assess the effect and permanence of intervention.


Data from the preintervention period (n=29) showed median ankle position was 32° plantarflexion (PF), with nine (31%) inadequate reductions and six (20%) backslabs reapplied. Following Plan-Do-Study-Act (PDSA) 1, ankle position was significantly improved (median 25° PF), there were fewer inadequate reductions (12%; 2/17) and a lower rate of reapplication (0%; 0/17). After PDSA 2 (n=16), median ankle position was 21° PF, there was one (6%) inadequate reduction and two (12%) reapplications of casts.


Following implementation of plaster training sessions for accident and emergency and junior orthopaedic staff, in addition to publishing guidance and new protocol, there has been a sustained improvement in the quality of below-knee backslabs and fewer cast reapplications. These findings justify continuation and expansion of the current programme to include other commonly applied plaster casts.

<![CDATA[Surgical quality in organ procurement during day and night: an analysis of quality forms]]>


To analyse a potential association between surgical quality and time of day.


A retrospective analysis of complete sets of quality forms filled out by the procuring and accepting surgeon on organs from deceased donors.


Procurement procedures in the Netherlands are organised per region. All procedures are performed by an independent, dedicated procurement team that is associated with an academic medical centre in the region.


In 18 months’ time, 771 organs were accepted and procured in The Netherlands. Of these, 17 organs were declined before transport and therefore excluded. For the remaining 754 organs, 591 (78%) sets of forms were completed (procurement and transplantation). Baseline characteristics were comparable in both daytime and evening/night-time with the exception of height (p=0.003).

Primary outcome measure

All complete sets of quality forms were retrospectively analysed for the primary outcome, procurement-related surgical injury. Organs were categorised based on the starting time of the procurement in either daytime (8:00–17:00) or evening/night-time (17:00–8:00).


Out of 591 procured organs, 129 organs (22%) were procured during daytime and 462 organs (78%) during evening/night-time. The incidence of surgical injury was significantly lower during daytime; 22 organs (17%) compared with 126 organs (27%) procured during evening/night-time (p=0.016). This association persists when adjusted for confounders.


This study shows an increased incidence of procurement-related surgical injury in evening/night-time procedures as compared with daytime. Time of day might (in)directly influence surgical performance and should be considered a potential risk factor for injury in organ procurement procedures.

<![CDATA[Improving the quality of administration of the Surgical Safety Checklist: a mixed methods study in New Zealand hospitals]]>

While the WHO Surgical Safety Checklist (the Checklist) can improve patient outcomes, variable administration can erode benefits. We sought to understand and improve how operating room (OR) staff use the Checklist. Our specific aims were to: determine if OR staff can discriminate between good and poor quality of Checklist administration using a validated audit tool (WHOBARS); to determine reliability and accuracy of WHOBARS self-ratings; determine the influence of demographic variables on ratings and explore OR staff attitudes to Checklist administration.


Mixed methods study using WHOBARS ratings of surgical cases by OR staff and two independent observers, thematic analysis of staff interviews.


OR staff in three New Zealand hospitals.

Outcome measures

Reliability of WHOBARS for self-audit; staff attitudes to Checklist administration.


Analysis of scores (243 participants, 2 observers, 59 cases) supported tool reliability, with 87% of WHOBARS score variance attributable to differences in Checklist administration between cases. Self-ratings were significantly higher than observer ratings, with some differences between professional groups but error variance from all raters was less than 10%. Key interview themes (33 interviewees) were: Team culture and embedding the Checklist, Information transfer and obstacles, Raising concerns and ‘A tick-box exercise’. Interviewees felt the Checklist could promote teamwork and a safety culture, particularly enabling speaking up. Senior staff were of key importance in setting the appropriate tone.


The WHOBARS tool could be useful for self-audit and quality improvement as OR staff can reliably discriminate between good and poor Checklist administration. OR staff self-ratings were lenient compared with external observers suggesting the value of external audit for benchmarking. Small differences between ratings from professional groups underpin the value of including all members of the team in scoring. We identified factors explaining staff perceptions of the Checklist that should inform quality improvement interventions.

<![CDATA[Prevention of acute kidney injury through accurate fluid balance monitoring]]>

Acute kidney injury (AKI) is associated with increased patient morbidity, mortality and an extended hospital stay. The financial burden to the National Health Service is high and it can affect up to one in five inpatients. Optimal fluid balance management is essential for the prevention of AKI and this can be particularly challenging in the patient with trauma. Our aim was to reduce the rate of AKI in patients with traumatic injuries in the regional trauma centre.

We developed new fluid balance charts and documented how well these were completed. The number of AKI alerts per month was calculated on our pathology system. Scenario training was delivered at handover meetings and an e-learning tool was designed at three levels: healthcare assistants; nurses; and medical staff, dietetics and pharmacists. Educational posters were placed in clinical areas and patient information leaflets produced. Junior doctors were regularly informed of AKI rates on the ward.

The number of AKI alerts on our trauma ward declined from 50 in January 2016 to 19 in November 2016. The mean monthly rate of AKI fell 33% following the invention (P<0.001). Completion of fluid balance charts improved; 6 hourly urine output documentation increased from 36% to 68% and running 1 hourly output increased from 80% to 96%. Calculation of total daily fluid balance rose from 12% to 72%, before decreasing to 32%. This highlighted the need for continued encouragement.

Improved fluid balance monitoring led to a reduction in the prevalence of AKI in patients admitted to this trauma centre.

<![CDATA[Understanding cauda equina syndrome: protocol for a UK multicentre prospective observational cohort study]]>


Cauda equina syndrome (CES) is a potentially devastating condition caused by compression of the cauda equina nerve roots. This can result in bowel, bladder and sexual dysfunction plus lower limb weakness, numbness and pain. CES occurs infrequently, but has serious potential morbidity and medicolegal consequences. This study aims to identify and describe the presentation and management of patients with CES in the UK.

Methods and analysis

Understanding Cauda Equina Syndrome (UCES) is a prospective and collaborative multicentre cohort study of adult patients with confirmed CES managed at specialist spinal centres in the UK. Participants will be identified using neurosurgical and orthopaedic trainee networks to screen referrals to spinal centres. Details of presentation, investigations, management and service usage will be recorded. Both patient-reported and clinician-reported outcome measures will be assessed for 1 year after surgery. This will establish the incidence of CES, current investigation and management practices, and adherence to national standards of care. Outcomes will be stratified by clinical presentation and patient management. Accurate and up to date information about the presentation, management and outcome of patients with CES will inform standards of service design and delivery for this important but infrequent condition.

Ethics and dissemination

UCES received a favourable ethical opinion from the South East Scotland Research Ethics Committee 02 (Reference: 18/SS/0047; IRAS ID: 233515). All spinal centres managing patients with CES in the UK will be encouraged to participate in UCES. Study results will be published in medical journals and shared with local participating sites.

<![CDATA[A woman’s place is in theatre: women’s perceptions and experiences of working in surgery from the Association of Surgeons of Great Britain and Ireland women in surgery working group]]>


Surgery remains an inherently male-dominated profession. The aim of this study was to survey women working within the discipline, to understand their current perceptions, providing insight into their practical day-to-day lives, supporting an action-oriented change.

Design and setting

The link to a confidential, online survey was distributed through the Association of Surgeons of Great Britain and Ireland (ASGBI) social media platforms on Facebook and Twitter over a 2-week period in October 2017.


Women working in surgical specialties and actively responding to the link shared through the ASGBI social media platforms. No patients were involved in the study.

Primary and secondary outcome measures

Data were analysed through a mixed-methods approach. The quantitative data were analysed through descriptive statistics and qualitative analysis was undertaken using a constant comparative analysis of the participants’ comments, to identify salient patterns (themes).


A total of 81 female participants replied (42% response rate based on the Facebook group members), with 88% (n=71) perceiving surgery as a male-dominated field. Over half had experienced discrimination (59%, n=47), while 22% (n=18) perceived a ‘glass ceiling’ in surgical training. Orthopaedics was reported as the most sexist surgical specialty by 53% (n=43). Accounts of gendered language in the workplace were reported by 59% (n=47), with 32% (n=25) of surveys participants having used it. Overall, a lack of formal mentorship, inflexibility towards part-time careers, gender stereotypes and poor work–life balance were the main perceived barriers for women in surgical careers.


These findings highlight the implicit nature of the perceived discrimination that women report in their surgical careers. The ASGBI acknowledges these perceptual issues and relative implications as the first of many steps to create an action-oriented change by allowing all staff, regardless of gender, to reflect on their own behaviour, perceptions and the culture in which they work.
