Kommerell's diverticulum is a rare congenital anomaly of the aortic arch system in which there is a left- or right-sided aortic arch with an aberrant subclavian artery on the contralateral side. Patients with this anomaly can be asymptomatic or have features of tracheal or oesophageal compression. However, there is a rising suspicion that it may be a rare cause of unilateral vocal cord palsy through its compression of the recurrent laryngeal nerve. We describe a patient who had a long history of hoarse voice and left vocal cord palsy with no other obvious cause, who was found to have a Kommerell's diverticulum on a contrast-enhanced computed tomography scan.

Introduction: Large language models (LLM), such as Chat Generative Pre-trained Transformer (ChatGPT) and Bard utilise deep learning algorithms that have been trained on a massive data set of text and code to generate human-like responses. Several studies have demonstrated satisfactory performance on postgraduate examinations, including the United States Medical Licensing Examination. We aimed to evaluate artificial intelligence performance in Part A of the intercollegiate Membership of the Royal College of Surgeons (MRCS) examination.

Methods: The MRCS mock examination from Pastest, a commonly used question bank for examinees, was used to assess the performance of three LLMs: GPT-3.5, GPT 4.0 and Bard. Three hundred mock questions were input into the three LLMs, and the responses provided by the LLMs were recorded and analysed. The pass mark was set at 70%.

Results: The overall accuracies for GPT-3.5, GPT 4.0 and Bard were 67.33%, 71.67% and 65.67%, respectively (p = 0.27). The performances of GPT-3.5, GPT 4.0 and Bard in Applied Basic Sciences were 68.89%, 72.78% and 63.33% (p = 0.15), respectively. Furthermore, the three LLMs obtained correct answers in 65.00%, 70.00% and 69.17% of the Principles of Surgery in General questions (p = 0.67). There were no differences in performance in the overall and subcategories among the three LLMs.

Conclusions: Our findings demonstrated satisfactory performance for all three LLMs in the MRCS Part A examination, with GPT 4.0 the only LLM that achieved the pass mark set.

Background: The adoption of robotic platforms in upper gastrointestinal (GI) surgery is expanding rapidly. The absence of centralised guidance and governance in adoption of new surgical technologies may lead to an increased risk of patient harm.

Methods: Surgeon stakeholders participated in a Delphi consensus process following a national open-invitation in-person meeting on the adoption of robotic upper GI surgery. Consensus agreement was deemed met if >80% agreement was achieved.

Results: Following two rounds of Delphi voting, 25 statements were agreed on covering the training process, governance and good practice for surgeons' adoption in upper GI surgery. One statement failed to achieve consensus.

Conclusions: These recommendations are intended to support surgeons, patients and health systems in the adoption of robotics in upper GI surgery.

Introduction: This study aimed to assess carer attitudes towards the use of artificial intelligence (AI) in management of fractures in paediatric patients. As fracture clinic services come under increasing pressure, innovative solutions are needed to combat rising demand. AI programs can be used to diagnosis fractures, but patient perceptions towards its use are uncertain.

Methods: We conducted a cross-sectional survey of carers of paediatric patients presenting to fracture clinic at a tertiary care centre, combining single-best-answer questions and Likert-type questions. We investigated patient perception of clinical review in the emergency department (ED), disruption to school to attend fracture clinic, and attitudes towards AI.

Results: Of the paediatric fracture patients participating in this study, 45% were seen within two hours, 29% were seen between two and four hours, and 26% were seen after four hours; 75% were seen by both a nurse and a doctor, 16% were seen only by a nurse and 9% only by a doctor. A total of 61% of children had to take time off school for their appointment and 59% of parents had to take time off. Of all respondents, 56% agreed that more research is needed to reduce waiting times, 76% preferred a nurse or doctor to review their child's radiograph, 64% were happy for an AI program to diagnose their child's fracture, and 82% were happy with an AI program being used as an adjunct to a clinician's diagnosis.

Conclusions: Carer perceptions towards the use of AI in this setting are positive. However, they are not yet ready to relinquish human decision making to automated systems.

Studies have demonstrated the negative impact that work-related musculoskeletal disorders (WMSDs) have on surgeons. These are also likely to affect some allied healthcare professionals such as interventional radiologists. Problems from WMSDs include pain, diminished technical and cognitive performance, and work absence. These could contribute to burnout, to which surgeons are already vulnerable owing to other working practices such as shift patterns and long hours. WMSDs could negatively affect working performance, and lead to poorer surgical outcomes and patient care. Surgeons are at risk of WMSDs of the neck and back that result from fixed and damaging postures while operating. Some have reduced their operation numbers and working days as result of WMSDs. Theatre ergonomics (e.g. table positioning, operating stools and monitors), intraoperative breaks and stretching may improve WMSDs for some. Strength/resistance training (RT) may be used to prevent or mitigate WMSDs. RT can also enhance general health and concentration, and combat intraoperative fatigue. Low engagement times of moderate-intensity RT of 20 minutes, twice a week, improve neck and back pain from WMSDs. Moreover, RT has been shown to reduce all-cause mortality by up to 15%, increase bone density, improve proprioception and reduce the fear of movement due to pain. Alongside ergonomic improvement and stretching, we recommend RT as an activity to improve general health and WMSDs.

Mammary myofibroblastoma (MFB) is a rare benign spindle cell tumour predominantly affecting males, but also observed in postmenopausal females. Its diagnosis remains challenging owing to overlapping histological features with malignant lesions and limited tissue sampling in core biopsies. We present a case of incidentally discovered mammary MFB in a 63-year-old man and review its clinical, radiological and histopathological characteristics. The patient, who had a history of distal pancreatectomy and splenectomy, presented with an incidental left anterior chest wall nodule discovered on computed tomography scan. Clinical examination revealed a benign left retroareolar lump, confirmed by breast ultrasound and mammography. Ultrasound-guided core biopsy demonstrated characteristic spindle cells, prompting immunohistochemical staining confirming the diagnosis of MFB. The lesion was surgically excised with clear margins. Mammary MFB is commonly seen in postmenopausal women and older men, presenting as painless, mobile breast lumps. Imaging findings are nonspecific, resembling fibroadenomas or fat necrosis. Histologically, MFB lacks mammary ducts or lobules and displays characteristic spindle cells with collagenous stroma. Immunohistochemistry aids in differentiating it from other spindle cell tumours. Surgical excision is curative, with no reported cases with recurrence. Mammary MFB should be considered in the differential diagnosis of breast masses in males and postmenopausal women. Despite the challenges in diagnosis, its benign nature and favourable prognosis warrant timely recognition and appropriate management through surgical excision. Further research is needed to establish clear management guidelines and explore its underlying pathogenesis.

Introduction: Deficiencies in non-technical skills can severely impede the functioning of teams in high-intensity scenarios, such as in damage control surgery for the critically injured trauma patient. Truncated preoperative checklists, modified from the standard World Health Organization preoperative checklist, and situational reporting at intervals during surgery are long-established practices in the military, and are recommended in the National Health Service guidelines on major incidents. These tools allow the multiprofessional team to create a shared mental model of the anaesthetic and operative plan, thereby improving team efficiency. Our aim was to establish whether adult major trauma centres in England are using truncated preoperative checklists and situational reporting for damage control surgery.

Methods: An online survey was devised and distributed via the national programme of care for trauma in November 2020.

Results: Responses were received from all 23 adult major trauma centres in England. Nine centres (39.1%) reported using a truncated preoperative checklist for damage control surgery albeit in a variety of formats. Common components were blood products received and/or available, presence of allergies, tranexamic acid and antibiotic administration, availability of viscoelastic tests, equipment required, availability of cell saver, role allocation and reference to other personnel needed, and discussion of the plan. Twelve centres (52.2%) have formal policies in place for situational reporting. Again, these were in multiple formats but all focused on patient physiology to direct surgical planning.

Conclusions: We have identified key components to advanced communication aids for damage control surgery, providing a foundation on which other major trauma centres can build their own versions of these potentially lifesaving tools.

Introduction: Within the past five years there has been a significant increase in the number of international medical graduates (IMGs) joining the United Kingdom's (UK) workforce. Having mentors and supervisors who understand the needs of IMGs and clinical and cultural differences in the workplace can benefit in the transition to working in a new country. Improving knowledge of and understanding differences between general surgical training programmes and grades across different countries could therefore aid in the support of IMGs within the UK.

Methods: Data on general surgical training programmes of the top ten countries for the primary medical qualifications of IMGs in the UK were collected to provide comparison with the UK training programme.

Results: The following countries were included: UK, India, Pakistan, Nigeria, Egypt, Ireland, Sudan, Sri Lanka, Romania, Iraq and South Africa. Training programme lengths ranged from 3 to 10 years. Only some training programmes provide additional training and qualification in sub-specialisation in general surgery. Other differences included a requirement for internship/non specialist training prior to training, differences in lengths of time spent in other surgical specialties and a requirement for research.

Conclusion: Understanding the training programmes of other countries may help UK surgeons to understand the prior experience of IMGs and enable them to provide better training and support.

Introduction: The objective of this study was to assess the readability and quality of online written information on epistaxis.

Methods: The terms 'epistaxis' and 'nosebleed' were entered into Google. The first six webpages generated for each search term were screened. Readability was assessed using the Flesch-Kincaid Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG) Index and Gunning Fog Index (GFOG). Quality was assessed using the DISCERN instrument. Spearman's correlation between quality and readability was calculated.

Results: A total of 37 websites met the inclusion criteria. The mean and 95% confidence intervals for FRES, FKGL, SMOG and GFOG were 58.9 (55.3-62.5), 9.65 (8.74-10.6), 9.18 (8.57-9.8) and 12.5 (11.5-13.5), respectively. The DISCERN score was 34.3 (32.0-36.5). Weak negative correlation was noted between DISCERN and FRES (r_s = -0.15, p = 0.36).

Conclusions: Online information on epistaxis is generally of poor quality and low readability.

Introduction: The aim of this study was to assess the yield of the endoscopic investigations performed following the resolution of acute diverticulitis.

Methods: A retrospective multicentre study included patients with multislice computed tomography (MSCT)-proven diverticulitis, in four NHS hospitals, between January 2016 and April 2023. The primary outcome was the rate of colonic cancer in the diseased segment. Secondary outcomes included the rate of malignancy in the nondiseased colonic segments, the benign colonic polyp detection rate, the rate of malignancy in the resected surgical specimens in patients who underwent an emergency surgery on the index admission and the rate of complications in the investigated group.

Results: A total of 1,120 patients were included in the study, out of which 604 were females, with a median age of 61 years; 731 patients (65%) had uncomplicated diverticulitis (Hinchey 1A) while 389 (35%) had complicated diverticulitis (Hinchey 1B-4). Following the acute episode, 757 (74%) patients had subsequent endoscopic evaluation. The incidence of colorectal cancer (CRC) or advanced adenomas (AA) in patients with uncomplicated diverticulitis was 0.14%. In the complicated diverticulitis group, the incidence of CRC/AA in patients with Hinchey 1b and Hinchey 2 was 1.4% and 5.4%, respectively. Out of the 102 patients who underwent emergency colonic resection for suspected perforated diverticulitis, 18 (17.6%) had histological evidence of colonic malignancy.

Conclusions: Endoscopic investigations following uncomplicated diverticulitis have a low yield for sinister colonic pathology. Colonoscopy should be planned following complicated diverticulitis and in patients with uncomplicated diverticulitis with suspicious radiological finding on index imaging or in patients with ongoing clinical manifestations. In patients who undergo emergency surgery, oncological principles should be applied whenever possible.
