Abstract:
Background: The first year of the Covid-19 pandemic saw drastic changes to bariatric surgical practice, including postponement of procedures, altered patient care and impacting on the role of bariatric surgeons. The consequences of this both personally and professionally amongst bariatric surgeons has not as yet been explored. Aim(s): The aim of this research was to understand bariatric surgeons' perspectives of working during the first year of the pandemic to explore the self-reported personal and professional impact. Method(s): Using a retrospective, two phased, study design with global participants recruited from closed, bariatric surgical units. The first phase used a qualitative thematic analytic framework to identify salient areas of importance to surgeons. Themes informed the construction of an on-line, confidential survey to test the potential generalizability of the interview findings with a larger representative population from the global bariatric surgical community. Finding(s): Findings of the study revealed that the first year of the pandemic had a detrimental effect on bariatric surgeons both personally and professionally globally. Conclusion(s): This study has identified the need to build resilience of bariatric surgeons so that the practice of self-care and the encouragement of help-seeking behaviors can potentially be normalized, which will in turn increase levels of mental health and wellbeing.

Abstract:
Background: COVID-19 pandemic has taken the world by surprise with the depth and breadth of its effect on all walks of life, bariatric surgery being no exception. With the scientific literature hitherto unable to comment and ascertain the influence of the COVID-19 pandemic on bariatric surgery and the level of harm experienced by bariatric surgeons, we- TUGS 'Level of Harm' collaborative group- attempted to gauge the effect of the said pandemic on bariatrics surgery specifically vis a vis the level of harm experienced by bariatric surgeons due to the pandemic. Method(s): A virtual questionnaire- developed on both: Google forms and Survey Monkey- was circulated via TUGS social media platforms to reach bariatric consultant surgeons, fellows and residents practising throughout the world in a bid to explore the influence of the COVID-19 pandemic on their surgical practice including but not limited to the annual surgical volume including re-do surgeries volume and postoperative complications. Moreover, they were also requested to categorise their respective level of harm vis a vis bariatric surgical interventions they undertake. After de-identification of the data, SPSS (V.26) was adopted to undergo statistical analysis. After exploring the dataset by descriptive analyses, the Chi-square test was applied to pursue the association of categorical variables with the reported level of harm. A double-sided p-value of less than 0.05 was considered statistically significant. Result(s): 16.8% of the respondents (21/125) indicated no harm vis a vis bariatrics surgery work whereas a comparative 18.4% of the respondents (23/125) reported moderate harm with significant worsening of symptoms. None of those who indicated less than 10% increase in surgery waitlisted patients being subjected to endoscopic interventions (0/14) reported Moderate Harm for bariatrics surgery work with significant worsening of symptoms whereas 1 in every 3 of those who indicated between 10% to 25% increase in surgery waitlisted patients being subjected to endoscopic interventions (5/15) reported such level of harm for bariatrics surgery work. (p < 0.001) Upon exhaustive sub-group analysis, it was uncovered that 33.6% of bariatrics surgical professionals perceived no harm (no evidence of change in clinical condition) during gastric band or related surgery work with only 4% perceiving Moderate Harm (significant worsening of symptoms/ comorbidities control/ minor increase in medications) for such surgical interventions. All of those who reported No harm for gastric band or related surgical work reported that Single anastomosis duodeno-ileal bypass (SADI-S) accounts for 10% of their practice whereas none of those who indicated that SADI-S accounts for more than 10% of their practice reported No harm for such surgical work. (p = 0.019) Conclusion(s): The global snapshot illustrates a trend of low harm vis a vis bariatrics surgery work in surgical professionals practising in the private sector with a lesser number of patients developing COVID-19 postoperatively and no postoperative COVID-19 related mortality. The patient being subjected to endoscopic intervention portends a higher level of harm for bariatrics surgical work- strict adherence to criteria and safety protocols being a logical inference. For gastric band and related surgery work, preoperative COVID-19 testing appears to be influenced by confounders in its effect on the surgeon's level of harm for the said interventions warranting further exploration. SADI-S, at a cut-off of 10%, exhibits strong interaction with the surgeon's level of harm for gastric band insertion and relation surgery work. Women surgical professionals came out to exhibit equivalent mental resilience and technical prowess at par with their male colleagues when it came to bariatrics surgical intervention

Abstract:
INTRODUCTION: Workplace-based assessments (WBAs) are intended to maximise learning opportunities in surgical training. There is speculation as to whether mandatory assessments in this form contribute to a tick-box culture. The objective of this review was to investigate surgical trainees' attitudes towards WBAs. METHOD(S): This systematic review of qualitative studies was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement. The literature was searched on the Medline, Embase, PubMed and Web of Science databases on 22 March 2022. RESULT(S): Sixteen studies were included in the review, mostly carried out on users of the Intercollegiate Surgical Curriculum Programme portfolio in the UK. Trainees felt that WBAs were educationally useful, providing opportunity for feedback, but this was overshadowed by a pressure to reach a set annual quota for WBAs and achieve high scores. Other themes included inaccurate recording of WBAs, the role of WBAs as formative or summative assessments, engagement and accessibility of trainers, and lack of time to complete WBAs. CONCLUSION(S): Negative perceptions about WBAs were widespread among surgical trainees despite a recognition of their capacity to facilitate learning. This review supports the recent removal of the annual quota for WBAs in UK surgical training programmes.

Abstract:
Aims: Historically, the preferred procedure for perforated diverticular disease is Hartmann's procedure (Hp). Although reliably achieving source control, it's associated with a high rate of post-operative complications and a stoma which of ten becomes permanent. We reviewed our experience of patients undergoing Hp vs primary anastomosis (PA) for perforated diverticulitis. Method(s): All patients undergoing emergency resectional surgery for perforated diverticulitis between March 2015 and Jan 2021 were identified from The Hospital Episode Statistics (HES) data. Demographics were collected and The patient groups were case matched for age and Charleson Comorbidity Index (CCI), Computed Tomography (CT) appearance and intraoperative contamination data. Post-operative morbidity/mortality data was compared. Result(s): 105 patients were included. 15 patients had PA (without diversion) and 90 Hp. In The PA cohort were10 males, median age 52 (range 27-76). There were no anastomotic leaks. 30-day morbidities were superficial wound dehiscence (1) and early incisional hernia (1). Median post-operative stay was 9 days (range 5-25). Hp control group (age below 76, Charlson score 10and below, Hinchey 1-3 intraoperatively). Included 58 patients, 26 males, median age 60.5 (range 30-76). Median post-operative stay was 10.5 days (range 5-227). 2 patients required re-operation. 5 patients developed wound infections. At the time of the study 18 patients have undergone reversal, 6 are On active waiting-list for reversal. There was a single 30-day mortality (post-discharge). Conclusion(s):We have shown that PA is safe in selected cohort of patients and have identified that over 50% of patients undergoing Hp could have been considered for PA.

Abstract:
Aims: Hypocalcaemia is a common complication after parathyroidectomy for secondary hyperparathyroidism (SHpT) and is of ten The cause of a prolonged hospital stay post operatively. Although there is no current guidance on targets for total parathyroidectomy for SHpT, current guidance recommends a day-case rate of 90% for patients undergoing Surgery for primary hyperparathyroidism. Our centre has developed a safe protocol which allows us to perform total parathyroidectomies as a day-case procedure in patients with SHpT. This protocol, developed in conjunction with The renal physicians, involves giving The patients alpha calcidol pre-operatively for 5 days, to minimise The incidence of hypocalcaemia, and close monitoring of The calcium levels post operatively, to permit safe discharge. Method(s): We carried out a single centre retrospective study on all patients who underwent a total parathyroidectomy for SHpT between February 2005 and May 2021. All The patients received The alpha calcidol regimen pre-operatively. Data on patient baseline characteristics, peri-operative calcium, potassium and PTH levels, length of hospital stay, operative procedure details, hospital readmission and 30-day morbidity were collected. Result(s): 49 patients underwent a total parathyroidectomy during The study period. 67% of patients were discharged on day 0 or on day 1 post-operatively. Reasons for prolonged hospital stay in The remaining patients included refractory hyperkalaemia requiring dialysis, complications secondary to anaesthesia, as well as hypocalcaemia in a few cases. No patients required readmission during The 30-day post-operative period. Conclusion(s): Day-case Surgery for SHpT can be achieved safely with a pre-operative regimen of alpha calcidol and close monitoring of calcium levels post-operatively.

Abstract:
Aims: In many hospitals the availability of operating theatres and access to senior surgical and anaesthetic support diminishes during night hours. Therefore urgent surgery is sometimes postponed until the following morning rather than performed overnight, if judged to be safe. We aim to determine if a delay to laparoscopic appendicectomy in cases of acute appendicitis of over 12 hours, analogous to an overnight delay, is correlated to worse patient outcomes. Our primary outcome was delayed discharge from hospital. Our secondary outcomes were appendicitis severity, conversion, and post-operative complications. Method(s): We undertook a retrospective review of The medical records of patients who underwent laparoscopic appendicectomy at a UK district General hospital between 01/01/2018 and 30/08/2019. For each patient clinical and demographic information; and times of hospital admission, surgery, and discharge; were collected. Delayed discharged was defined as 'time to discharge' >24 hours. Result(s): 506 patients were included. In 144 patients (28.5%) 'time to surgery' was under 12 hours; in 362 patients (71.5%) 'time to surgery' was over 12 hours. 362 patients (71.5%) had a delayed discharge. 303 patients (59.9%) had Simple appendicitis; 143 patients had severe appendicitis (28.3%); 60 patients had a macroscopically normal appendix (11.9%). No statistically significant association between 'time to surgery' and delayed discharge, appendicitis severity, conversion or 30 day re-presentations was observed. Conclusion(s): Time from admission to start of appendicectomy did not affect patient outcomes. Short in-hospital delays to appendicectomy, for example an overnight delay, may be safe in certain patients, taking account of clinical judgement.

Abstract:Introduction: Aortic dissection (AD) is a life-threatening medical emergency that affects an estimated 3-4 people per 100,000 annually, with 40% of cases classified as type B AD (TBAD). TBAD can be further classified as being complicated (co-TBAD) or uncomplicated (un-TBAD) based on the presence or absence of certain features such as malperfusion and rupture. TBAD can be managed conservatively with optimal medical therapy (OMT), or invasively with open surgical repair (OSR) or thoracic endovascular aortic repair (TEVAR), depending on several factors such as type of TBAD and its clinical acuity. The cost-effectiveness, or cost-benefit profile, of these strategies must be given equal consideration. However, TBAD studies featuring cost analyses are limited within the literature. Aims: This narrative review aims to address the gap in the literature on cost effectiveness of TBAD treatments by providing an overview of cost-analyses comparing OMT with TEVAR in un-TBAD and TEVAR with OSR in co-TBAD. Another aim is to provide a market analysis of the commercially available TEVAR devices. Methods: A comprehensive literature search was performed using several search engines including PubMed, Ovid, Google Scholar, Scopus and EMBASE to identify and extract relevant studies. Results: Several TEVAR devices are available commercially on the global market costing $12,000-19,495. Nevertheless, the Terumo Aortic RELAY® stent-graft seems to be the most cost-effective, yielding highly favourable clinical outcomes. Despite the higher initial cost of TEVAR, evidence in the literature strongly suggest that it is superior to OMT for un-TBAD on the long-term. In addition, TEVAR is well established in the literature as being gold-standard repair technique for co-TBAD, replacing OSR by offering a more optimal cost-benefit profile through lower costs and improved results. Conclusion: The introduction of TEVAR has revolutionised the field of aortovascular surgery by offering a highly efficacious and long-term cost effective treatment for TBAD.

Abstract:Background: Type B aortic dissection (TBAD) occurs due to an entry tear in the intimal layer of the aorta distal to the origin of the left subclavian artery where blood enters the newly formed false lumen (FL) and extends distally or proximally to form a dissection over an indeterminate length of the aorta which, over time, may eventually rupture. Thoracic endovascular aortic repair (TEVAR) aims to seal off the entry tear proximally with the stent-graft, occluding the origin of the dissection and excluding the FL. Nevertheless, in some cases, the perfusion to the FL is maintained, hindering the aortic remodelling process and increasing the risk of aneurysmal degeneration and rupture, particularly in the abdominal aorta where evidence suggest that remodelling is slower. This review examines the long-term effects of a patent or partially thrombosed FL on clinical outcomes following TEVAR in TBAD, also highlighting the pathological processes behind negative aortic remodelling. Another aim of this review is to provide an overview and appraisal of the currently available techniques for managing a patent or partially thrombosed FL to prevent long-term morbidity occurring. Methods: A comprehensive literature search was performed using several search engines including PubMed, Ovid, Google Scholar, Scopus, and Embase to identify and extract relevant studies. Results: Evidence in the literature show that a partially thrombosed FL is more dangerous than a patent FL due to the occlusion of the distal re-entry tears, impeding outflow and increasing mean arterial and diastolic pressures, whereas the latter is decompressed via distal re-entry sites. FL thrombosis and satisfactory remodelling is sometimes achieved in as few as 40% of patients after TEVAR due to the maintained perfusion of the FL either at the level of the thoracic or abdominal aorta. However, although the thoracic aorta is predominantly covered by the TEVAR stent-graft, poorer remodelling and more dilation is seen in the abdominal aorta. Several techniques are available to embolize the FL, including the Provisional Extension to Induce Complete Attachment, Stent Assisted Balloon Induced Intimal Disruption and Relamination in Aortic Dissection Repair, candy-plug, and Knickerbocker techniques. Conclusions: The management of TBAD is invariably TEVAR to seal off the proximal entry tear while extending the repair distally to completely exclude the FL. A risk of aortic wall dilatation distal to TEVAR stent-graft remains; hence, regular monitoring and accurate imaging are essential. At present, a patent FL can be treated using a range of different endovascular techniques.

Abstract:
Background: The age group of patients presenting acutely with biliary pathology is rising and gallstone disease can no longer be said to be a disease of the young. The World Health Organisation classifies those aged 65 and over as elderly. Early cholecystectomy is accepted as a safe and effective method of managing acute biliary pathology, reducing further admissions, and reducing in-hospital stays. Our unit does not use age as barrier but uses performance status and co-morbidity to identify potential candidates for cholecystectomy. Method(s): Patients over the age of 65 who underwent acute cholecystectomy (AC) via the emergency cholecystectomy lists, were audited from 31st December 2019 to 31st June 2021. Patient demographics, co-morbidities and surgical factors were recorded. The primary outcome measures were in-hospital stay and re-admission, secondary outcomes were complications and perioperative mortality. Result(s): 41 elderly patients underwent AC during the audit period, (Female 56%, Male 44%). 30 patients had acute cholecystitis (73%). The median inpatient stay following surgery was 2 days (range 2-5 days) and the median admission to surgery time was 6 days (range 5-12 days). Three patients had a subtotal cholecystectomy. There were 3 complications from surgery which were all between a Clavien-Dindo score of 2 and 3. There were 3 immediate post-operative readmissions, with one 30-day mortality from ERCP pancreatitis and not from the operation. Conclusion(s): Early cholecystectomy appears to be a safe and effective treatment for this group of patients and based on this evidence we should continue to offer this treatment to patients irrespective of age.

Abstract:
Aim: Limited hours and service provision are diminishing training opportunities for surgical trainees. It is therefore imperative to maximise each educational event in theatre. The Operating Room Educational Environment Measure (OREEM) evaluates each component of the theatre learning environment; however, it has not been validated in higher surgical trainees in England. We aim to validate the OREEM and evaluate surgical trainees' objective perspectives of the current operating room educational environment in one region. Method(s): Data was collected over one month from surgical trainees within Health Education Thames Valley using an online questionnaire consisting of: demographic data; the OREEM; a global satisfaction score. Result(s): 54 trainees participated. The OREEM had good internal consistency (alpha=0.906, variables=40) and unidimensionality. Mean OREEM score was 79.16%. Areas for improvement included better learning opportunities (72.9%) and pre/post-operative teaching (70.4%). Trainees were most satisfied with the level of supervision and workload (82.9%). No differences between gender (p=0.535) or hospital type (p=0.099) were demonstrated. The learning environment favoured senior trainees (p=0.017). There was a strong correlation between OREEM and the global satisfaction score (p<0.001). Conclusion(s): The OREEM was shown to be a reliable measure of the educational environment in theatre. It can be used to identify areas of improvement and as an audit tool. Suggested areas of improvement include facilitating pre- and post-operative teaching, reducing service provision, empowering trainees to plan lists, improving teamwork and using tools to optimise the educational value of each operation. There is a favourable attitude regarding the use of such improvement tools, especially for dissatisfied trainees.
