Abstract:
BACKGROUND Complicated intra-abdominal infections (cIAIs) are associated with significant morbidity and mortality. The aim of this study was to describe the clinical characteristics of patients with cIAI in a multicentre study and to develop clinical prediction models (CPMs) to help identify patients at risk of mortality or relapse.METHODS A multicentre observational study was conducted from August 2016 to February 2017 in the UK. Adult patients diagnosed with cIAI were included. Multivariable logistic regression was performed to develop CPMs for mortality and cIAI relapse. The c-statistic was used to test model discrimination. Model calibration was tested using calibration slopes and calibration in the large (CITL). The CPMs were then presented as point scoring systems and validated further.RESULTS Overall, 417 patients from 31 surgical centres were included in the analysis. At 90 days after diagnosis, 17.3 per cent had a cIAI relapse and the mortality rate was 11.3 per cent. Predictors in the mortality model were age, cIAI aetiology, presence of a perforated viscus and source control procedure. Predictors of cIAI relapse included the presence of collections, outcome of initial management, and duration of antibiotic treatment. The c-statistic adjusted for model optimism was 0.79 (95 per cent c.i. 0.75 to 0.87) and 0.74 (0.73 to 0.85) for mortality and cIAI relapse CPMs. Adjusted calibration slopes were 0.88 (95 per cent c.i. 0.76 to 0.90) for the mortality model and 0.91 (0.88 to 0.94) for the relapse model; CITL was -0.19 (95 per cent c.i. -0.39 to -0.12) and – 0.01 (- 0.17 to -0.03) respectively.CONCLUSION Relapse of infection and death after complicated intra-abdominal infections are common. Clinical prediction models were developed to identify patients at increased risk of relapse or death after treatment, although these require external validation.

Abstract:
Due to the COVID-19 pandemic most oral and maxillofacial surgical (OMFS) units have moved to conducting patient consultations over the telephone. The aim of this study was to assess patients' satisfaction with telephone consultations during the COVID-19 pandemic. A retrospective survey was conducted of OMFS patients at our hospital who had telephone consultations between 1 April – 8 June 2020. The survey was conducted by independent interviewers and used the Generic Medical Interview Satisfaction Scale (G-MISS) along with a previously published additional questionnaire. Variables recorded included age, gender, theme of consultation, grade of clinician, and type of consultation. Statistical analysis was performed to assess for any differences between patient groups. The records of 150 consecutive patients were reviewed and 135 met inclusion criteria. A total of 109 patients completed the survey giving a response rate of 80.74%. The total G-MISS score for satisfaction was high, which indicates a high level of satisfaction among all patients. We found no statistical difference in satisfaction when comparing patients in terms of gender, age, theme of consultation, or level of clinician. A significant difference was found in compliance levels between review and new patients, with review patients demonstrating higher compliance levels (p=0.004). Overall, 83.48% of patients said they would be willing to have a telephone consultation in future. The majority of patients in this study reported high levels of satisfaction with telephone consultations. New patients reported lower levels of compliance which may suggest this type of consultation is less suited to telephone consultation.

Abstract:
The infection control measures implemented as a result of COVID-19 led to a postponement of bariatric surgical procedures across many countries worldwide. Many bariatric surgical teams were in essence left without a profession, with many redeployed to other areas of clinical care and were not able to provide the levels of patient support given before COVID-19. As the pandemic continues, some restrictions have been lifted, with staff adjusting to new ways of working, incorporating challenging working conditions and dealing with continuing levels of stress. This article explores the concept of emotional labour, defined as 'inducing or suppressing feelings in order to perform one's work', and its application to multidisciplinary teams working within bariatric surgery, to offer insight into the mental health issues that may be affecting healthcare professionals working in this discipline.

Abstract:
Background: Laparoscopic ventral mesh rectopexy (LVMR) is an established treatment for external full-thickness rectal prolapse. However, its clinical efficacy in patients with internal prolapse is uncertain due to the lack of high-quality evidence.
Methods: An individual level, stepped-wedge randomised trial has been designed to allow observer blinded data comparisons between patients awaiting LVMR with those who have undergone surgery. Adults with symptomatic internal rectal prolapse, unresponsive to prior conservative management, will be eligible to participate. They will be randomised to three arms with different delays before surgery (0, 12 and 24 weeks). Efficacy outcome data will be collected at equally stepped time points (12, 24, 36 and 48 weeks). The primary objective is to determine clinical efficacy of LVMR compared to controls with reduction in the Patient Assessment of Constipation Quality of Life (PAC-QOL) at 24 weeks serving as the primary outcome. Secondary objectives are to determine: (1) the clinical effectiveness of LVMR to 48 weeks to a maximum of 72 weeks; (2) preoperative determinants of outcome; (3) relevant health economics for LVMR; (4) qualitative evaluation of patient and health professional experience of LVMR and (5) 30-day morbidity and mortality rates.
Results: An individual-level, stepped-wedge, randomised trial serves the purpose of providing an untreated comparison for the active treatment group, while at the same time allowing the waiting-listed participants an opportunity to obtain the intervention at a later date. Conclusions: In keeping with the basic ethical tenets of this design, the average waiting time for LVMR (12 weeks) will be shorter than that for routine services (24 weeks).

Abstract:
Objectives: To evaluate the comparative outcomes of three-dimensional (3D) versus two-dimensional (2D) imaging during laparoscopic cholecystectomy.
Method(s): We conducted a systematic search of electronic information sources and bibliographic reference lists and applied a combination of free text and controlled vocabulary search adapted to thesaurus headings, search operators and limits. Procedure time, Calot's triangle dissection time, gallbladder removal time, gallbladder perforation, intraoperative bleeding, postoperative complications, conversion to open and intraoperative errors were the evaluated outcome parameters.
Result(s): We identified 6 randomised controlled trials (RCT) reporting a total of 577 patients who underwent laparoscopic cholecystectomy using 3D (n = 282) or 2D (n = 295) imaging. The 3D imaging was associated with significantly shorter procedure time (MD – 4.23, 95% CI – 8.14 to – 0.32, p = 0.03), Calot's triangle dissection time (MD – 4.19, 95% CI – 6.52 to – 1.86, p = 0.0004) and significantly lower risk of gallbladder perforation (RR 0.50, 95% CI 0.28-0.88, p = 0.02) compared to the 2D approach. No significant difference was found in gallbladder removal time (MD – 0.79, 95% CI – 2.24 to 0.66, p = 0.28), intraoperative bleeding (RR 1.14, 95% CI 0.68-1.90, p = 0.61), postoperative complications (RD – 0.01, 95% CI – 0.06 to 0.05, p = 0.85), conversion to open (RD 0.00, 95% CI – 0.02 to 0.03, p = 0.70) or intraoperative errors (RR 0.96, 95% CI 0.79-1.17, p = 0.70) between the two groups.
Conclusion(s): Although our findings suggest that the use of 3D imaging during laparoscopic cholecystectomy may be associated with significantly shorter procedure time, Calot's triangle dissection time and gallbladder injury compared to the 2D imaging, the differences seem to be clinically insignificant. Moreover, both approaches carry s similar risk of postoperative morbidities. The impact of the surgeon's level of experience and difficulty of the procedure on the outcomes of each imaging modality remains unknown.

Abstract:
Aims: Duplication of the gallbladder is a rare congenital anomaly. However, awareness of this anatomical variation is crucial when treating gallstone disease. We present the case of a patient with two gallbladders, incidentally found during laparoscopic cholecystectomy. We review the literature and discuss the associated surgical challenges.
Methods: Case presentation and literature review of the classification, clinical presentation, radiological diagnosis and management of gallbladder duplication.
Results: A 37 year old healthy man presented with a two year history of post prandial right upper quadrant abdominal pain. Routine blood investigations were normal and ultrasonography (US) demonstrated gallstones with normal biliary ducts. During laparoscopy he was found to have gallbladder duplication with a Y-shaped type cystic duct, this consisted of two ducts joining together to form a main cystic duct which drained into an otherwise normal common bile duct. No cholangiogram was performed. After meticulous dissection and demonstration of the anatomy, the cholecystectomy was performed. The patient recovered uneventfully and was discharged the next day. Histology showed gallstones and chronic inflammation in both
gallbladders.
Conclusions: A duplicate gallbladder is a rare congenital variation. Preoperative diagnosis can be challenging. Understanding its classification based on the relational anatomy to the biliary tree is essential to avoid biliary injuries. Imaging modalities such as US and computed tomography (CT) may not be sensitive enough. MRCP may demonstrate the biliary tree more clearly. Laparoscopic cholecystectomy can be safely performed, in the presence of symptomatic gallstone disease.

Abstract:
Perioperative tranexamic acid use is a popular choice among many surgeons for reducing surgical blood loss and its sequelae. While there is evidence in the literature that tranexamic acid use is effective in reducing blood loss in surgery for patients with hip fractures, there is less information on whether it leads to thromboembolic complications. We undertook a retrospective study in patients with hip fractures at two local hospitals to investigate if there was an increased risk of venous thromboembolism in patients who received tranexamic acid, and whether it reduced perioperative blood loss and the need for transfusion. We found that tranexamic acid used in patients undergoing hip fracture surgery reduced the drop in postoperative haemoglobin and the need for postoperative blood transfusion but was not associated with an increased risk of venous thromboembolism.

Abstract:
Surgical case cancellation has significant impacts on operating theatre efficiency and the UK loses a substantial amount of money on these cases [1]. A recent prospective study over a 1-week period in an NHS hospital suggested a adult surgical case cancellation rate between 10% and 14% and the majority of these cases were due to non-clinical reasons [2]. It is distressing for the patient and affects outcomes. We undertook an audit regarding cancellation of paediatric surgical cases on the day of surgery at a district general hospital (DGH) to look for various reasons for the cancellations and to evaluate the services. Methods We collected prospective data from the hospital's database regarding cancelled paediatric surgical procedures over a 6-month period from February 2018 to July 2018 in our DGH. Results We found that a total of 70 paediatric surgical cases were cancelled on the day of surgery out of total of 653 paediatric surgical cases, which is an approximately 10% cancellation rate over the 6-month period with a range of cancellations from 7% in May and June to 18% in February. We observed that 76% of the cancellations were of elective cases. We subdivided the reasons for cancellations into organisational, patient, surgical and anaesthetic factors. Among the organisational factors, 23% of cancellations were due to 'unavailable beds'. We observed that 11% of cancellations occurred because patients 'did not attend', 7% of patients were reported as 'sick' and 3% of patients did not follow preoperative fasting instructions. Surgeons cancelled 15% of cases for the reason 'procedure no longer required', whereas anaesthetist 'sickness' was the reason for cancellation in 9% of cases. Discussion Cancellations prolong the waiting list and worsens patient experiences and clinical outcomes. In our audit, we found that the main reasons for cancellations were non-clinical. To improve the surgical reasons for cancellation, we suggest timely rereview of the need for surgery. Although staff allocation is looked at regularly, some cases were cancelled due to the unavailability of staff, which can be improved on. We discussed the idea of seasonal planning of cases. We plan to re-audit with the aim of investigating cancellation rates in elective cases over a 1-year period to also review the cancellation rate during the winter months.
