Abstract:
Aim: Type II endoleaks following EVAR are caused by patent aortic collaterals causing retrograde blood flow, with the IMA being involved in 45-85% of all cases. Transarterial embolization has been described as a management option, but with a high failure rate. We present laparoscopic ligation as an alternative therapeutic strategy, with both technical success and a favourable outcome.
Method(s): An 80-old hypertensive male was diagnosed with a type II endoleak post-EVAR. Shrinkage of the sac was seen initially from 58mm to 52mm on surveillance-computed tomography (CT) of the aorta at 6 months with apersistent type II endoleak involving the IMA and lumbar arteries. Surveillance at 18 months demonstrated a persistent endoleak with enlargement of the sac to 65 mm. After a failed attempt with arterial embolization, he underwent laparoscopic ligation of the IMA Results: The procedure time was 22 minutes and his length of stay was 2 days, with no signs or symptoms of bowel ischaemia. A CT at 2 weeks demonstrated sac shrinkage to 58 mm. Conclusion(s): There have been reports of persistent endoleaks being associated with adverse outcomes, with their primary management remaining controversial. IMA ligation has been associated with sac shrinkage in 65% of patients, an important prognostic factor, and there have been no reported complications thus far. Therefore, it should be strongly considered as an option for management of type II endoleaks in centres with both vascular and general surgical expertise being available

Abstract:
Aims: The awareness of Human Factors (HF) and their role in patient safety is vital in the theatre environment.
The aim of this audit was therefore to assess the awareness of human factors within our theatre team during a Human Factors Training Course at a District General Hospital.
Method(s): The Human Factors Training Course started with a questionnaire assessing roles, experience, and awareness of HF. It also looked at staff morale. The course involved a presentation and 2 simulation scenarios in theatre. After completion, there was a post course questionnaire looking at awareness of human factors, effects on staff morale and impact on patient care.
Result(s): Of the respondents, experience varied from 1 to 10+ years. The pre-course awareness of HF averaged 6.1 out of 10. The opinions on morale averaged at 6.7 out of 10, and the effect of HF training on morale averaged 8.4 out of 10. All respondents believed that the course could improve patient care. Post course awareness of HF increased and staff morale also increased as a consequence of the course.
Conclusion(s): From the results we can see that the awareness of human factors within the cohort prior to training was relatively low. Post course, we can see an increase in terms of awareness of human factors. As well as providing a training opportunity, this course had a positive effect on staff morale, and vitally, it was thought that the course would have positive impact on patient care.

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.
