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:
The ureteral insertion of a silicone tube was first performed in 1967. A validated ureteral stent symptom questionnaire (USSQ) is used for an objective assessment of patient-reported stent-related symptoms. As the impact of stent diameter on the incidence of stent-related symptoms is unclear, we aimed to perform a systematic review and meta-analysis comparing USSQ reported outcomes when using a 6 Fr diameter ureteric stent, versus smaller diameter stents (4.7-5 Fr) when inserted for ureteric stones. All randomized control trials and comparative studies of 6 Fr versus 4.7-5 Fr ureteric stents were reviewed. The USSQ outcomes were considered as the primary outcome measures while stent migration was considered as a secondary outcome measure. A total of 61 articles were identified of which four studies met the eligibility criteria. There was a statistically significant association between the use of wider (6 Fr) diameter stents and the incidence of urinary symptoms as measured by the urinary index score. Larger stent diameters were associated with a statistically significant increase in the pain index score. There was no statistically significant difference in the scores between the compared stent diameters with regard to work performance score, general health index score, additional problems index score, and stent migration. There were insufficient reported outcomes to perform a meta-analysis of sexual matters index score. Our meta-analysis shows that using smaller diameter ureteric stents is associated with reduced urinary symptoms and patient-reported pain. Other USSQ parameter outcomes are statistically similar in the 6 Fr ureteric stent cohort versus the 4.7-5 Fr ureteric stent cohort. Our meta-analysis was limited due to the limited number of studies and gross heterogeneity of reporting parameters in various studies. We hope a large-scale homogeneous randomized control trial will further shed more insight into the stent symptoms response to stent diameter

Patient experiences of weight loss and eating after bariatric surgery: A Systematic Review and Qualitative Synthesis (2023)

Posted on by

Type of publication:Journal article

Author(s):*Ansari M; Serjeant S

Citation:Journal of Human Nutrition & Dietetics. 36(4):1438-1450, 2023 Aug.

Abstract:Background: An estimated 26% of men and 29% of women in the UK are living with obesity according to recent statistics. Bariatric Surgery (BS) can induce significant weight loss and improve co-morbidity status. However previous studies highlight challenges in maintaining dietary changes and weight loss. This systematic review aimed to investigate patient experiences of weight loss and eating in the first two years following surgery, to provide clinical recommendations to support this group.Methods: Ethical approval was granted by the University. A systematic search was conducted in four databases. Studies were selected according to the predefined eligibility criteria and methodological quality, assessed via the CASP tool. Data were extracted and analysed using a thematic synthesis method. Rigour was enhanced via use of a data extraction tool, a validated method for data synthesis, peer-review and transparent reporting.Results: In total, 507 records were screened; nine studies met the inclusion criteria. The thematic synthesis yielded four, interlinked analytical themes based on 154 patients' experiences: relationship with food, relationship with oneself, relationship with others and unfinished journey. Positive experiences were reported including development of healthy eating behaviours and significant weight loss, improving physical and psychosocial wellbeing. On the other hand, challenges in adjusting to life after surgery were also reported.Conclusions: This study highlighted the need for personalised dietary advice, addressing the psychological aspects of eating. Support should be extended to the family. Ongoing psychological support must be incorporated in the post-surgery care pathway to help patients deal with the negative outcomes of surgery such as excess skin.

Abstract:Objectives: Management strategies of the Covid pandemic included isolation to prevent transmission. This study aimed to determine if the pandemic of 2020 influenced the epidemiology of Achilles Tendon Rupture (ATR).Methods: The demographics of presentations from the local population to xxx hospital, Shropshire, United Kingdom with an ATR were analysed and compared together with the season, month, and year of the injury.Results: From 2009 to 2019 there was no significant change in the incidence of ATR over time with mean (SD) incidence of 13.3 per 100,000. In 2020, there was a decrease in injuries with an incidence of 8.4 per 100,000, with an increase in 2021 to 22.4 per 100,000. In 2021, there was an increase in injuries from March with numbers maintained until October. The most common activity of ATR was Team sport (36.2%), followed by Activities of Daily Living (28.9%), Other physical activities (21.0%) and Racket sports (13.9%). In 2020 there was the lowest number of injuries sustained in Team and Racket sports, however in 2021 they accounted for over half of Injuries.Conclusions: There were significantly more patients sustaining ATR in 2021, the year after the covid pandemic and mandatory isolation. This was considered to be related to altered activity and Team and Racket sports during 2020.Levels of Evidence: IV Case series.

Abstract:Background: Limited hours and service provision are diminishing training opportunities, whilst increasing standards of surgical proficiency is being sought. It is imperative to maximise the value of each educational event. An objective measure of higher surgical trainee perception of the operating room environment in England has not been performed before and this can steer future change in optimising educational events in theatre. The Operating Room Educational Environment Measure (OREEM) evaluates each component of the learning environment to enable optimisation of these educational events. However, the OREEM has not yet been assessed for reliability in higher surgical trainees in England. The aim of the current study was to explore areas of strength and weakness in the educational environment in the operating room as perceived by surgical trainees' in one English region. The secondary aim was to assess the reliability of the OREEM.Methods: Using a quantitative approach, data was collected over one month from surgical trainees in England using the OREEM.Results: Fifty-four surgical trainees completed the questionnaire. The OREEM had good internal consistency (α = 0.906, variables = 40). The mean OREEM score was 79.16%. Areas for improvement included better learning opportunities (average subscale score = 72.9%) and conducting pre- and post-operative teaching (average score = 70.4%). Trainees were most satisfied with the level of supervision and workload (average subscale score = 82.87%). The learning environment favoured senior trainees (p = 0.017). There was a strong correlation between OREEM and the global satisfaction score (p < 0.001).Conclusions: The OREEM was shown to be a reliable measure of the educational environment. It can be used to identify areas of improvement and as an audit tool. The current perception of the education environment is satisfactory, however, areas of improvement include 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 improvement tools, especially for dissatisfied trainees.

Abstract:Introduction: Large-for-gestational age (LGA) fetuses have an increased risk of shoulder dystocia. This can lead to adverse neonatal outcomes and death. Early induction of labour in women with a fetus suspected to be macrosomic may mitigate the risk of shoulder dystocia. The Big Baby Trial aims to find if induction of labour at 38+0-38+4 weeks' gestation, in pregnancies with suspected LGA fetuses, reduces the incidence of shoulder dystocia.Methods and Analysis: The Big Baby Trial is a multicentre, prospective, individually randomised controlled trial of induction of labour at 38+0 to 38+4 weeks' gestation vs standard care as per each hospital trust (median gestation of delivery 39+4) among women whose fetuses have an estimated fetal weight >90th customised centile according to ultrasound scan at 35+0 to 38+0 weeks' gestation. There is a parallel cohort study for women who decline randomisation because they opt for induction, expectant management or caesarean section. Up to 4000 women will be recruited and randomised to induction of labour or to standard care. The primary outcome is the incidence of shoulder dystocia; assessed by an independent expert group, blind to treatment allocation, from delivery records. Secondary outcomes include birth trauma, fractures, haemorrhage, caesarean section rate and length of inpatient stay. The main trial is ongoing, following an internal pilot study. A qualitative reporting, health economic evaluation and parallel process evaluation are included.

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.

Fate and Consequences of the False Lumen After Thoracic Endovascular Aortic Repair in Type B Aortic Dissection (2023)

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.
