Abstract
OBJECTIVES To develop and validate a predictive model to predict the risk of postoperative mortality after emergency laparotomy taking into account the following variables: age, age ≥ 80, ASA status, clinical frailty score, sarcopenia, Hajibandeh Index (HI), bowel resection, and intraperitoneal contamination. SUMMARY BACKGROUND DATA The discriminative powers of the currently available predictive tools range between adequate and strong; none has demonstrated excellent discrimination yet. METHODS The TRIPOD and STROCSS statement standards were followed to protocol and conduct a retrospective cohort study of adult patients who underwent emergency laparotomy due to non-traumatic acute abdominal pathology between 2017 and 2022. Multivariable binary logistic regression analysis was used to develop and validate the model via two protocols (Protocol A and B). The model performance was evaluated in terms of discrimination (ROC curve analysis), calibration (calibration diagram and Hosmer-Lemeshow test), and classification (classification table). RESULTS One thousand forty-three patients were included (statistical power = 94%). Multivariable analysis kept HI (Protocol-A: P =0.0004; Protocol-B: P =0.0017), ASA status (Protocol-A: P =0.0068; Protocol-B: P =0.0007), and sarcopenia (Protocol-A: P <0.0001; Protocol-B: P <0.0001) as final predictors of 30-day postoperative mortality in both protocols; hence the model was called HAS (HI, ASA status, sarcopenia). The HAS demonstrated excellent discrimination (AUC: 0.96, P <0.0001), excellent calibration ( P <0.0001), and excellent classification (95%) via both protocols. CONCLUSIONS The HAS is the first model demonstrating excellent discrimination, calibration, and classification in predicting the risk of 30-day mortality following emergency laparotomy. The HAS model seems promising and is worth attention for external validation using the calculator provided.

The GP's role in supporting women with anal incontinence after childbirth injury. Br J Gen Pract 2024:BJGP.2023.0356. [PMID: 38359950 DOI: 10.3399/bjgp.2023.0356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 01/03/2024] [Indexed: 02/17/2024] Open
Abstract
BACKGROUND Obstetric anal sphincter injury is the most common cause of anal incontinence (AI) for women, which often has profound impacts on women's lives. GPs offer a first line of contact for many, but we know that very few women experiencing AI postnatally report discussing it with their GPs. DESIGN AND SETTING Qualitative study investigating women's experiences with their GP and GPs' perspectives about providing such care. AIM The study aims to identify key ways GPs can support women with AI due to childbirth injuries. METHOD This qualitative study combined two phases: firstly, a series of in-depth interviews with women experiencing AI caused by childbirth injuries (n=41); secondly, focus groups with GPs (n=13) stratified by experience. Thematic analysis was conducted and relevant themes from across the two datasets were examined. RESULTS Mediating factors in GP care for women with AI caused by childbirth injuries centred around three key themes: Role of the GP, Access and Pathways, and Communication. CONCLUSION The findings demonstrate multifactorial challenges in identifying the problem and supporting women experiencing AI after childbirth injury within primary care settings. Many GPs lacked confidence in their role in supporting women and women were often reluctant to seek help. Those who did often experienced frustrations consulting with their GPs. In a context where women are often reluctant to ask for help, concerns are not always taken seriously, and where GPs do not routinely ask about AI, potential AI after childbirth injury appears to be often missed in a primary care setting.

Women's experiences of anal incontinence following vaginal birth: A qualitative study of missed opportunities in routine care contacts. PLoS One 2023; 18:e0287779. [PMID: 37368897 DOI: 10.1371/journal.pone.0287779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 06/13/2023] [Indexed: 06/29/2023] Open
Abstract
OBJECTIVES This study aimed to explore experiences of women with anal incontinence following a childbirth injury, and to identify areas of missed opportunities within care they received. DESIGN This is a qualitative study involving semi-structured interviews. SETTING Participants were recruited via five hospitals in the UK, and via social media adverts and communication from charity organisations. PARTICIPANTS Women who have experienced anal incontinence following a childbirth injury, either within 7 years of sustaining the injury, or if they identified new, or worsening symptoms of AI at the time of menopause. MAIN OUTCOME MEASURES Main outcomes are experiences of women with anal incontinence following childbirth injury, and missed opportunities within the care they received. RESULTS The following main themes were identified: opportunities for diagnosis missed, missed opportunities for information sharing and continuity and timeliness of care. CONCLUSIONS Anal Incontinence following a childbirth injury has a profound impact on women. Lack of information and awareness both amongst women and healthcare professionals contributes to delays in accurate diagnosis and appropriate treatment.

Innovations towards achieving environmentally sustainable operating theatres: A systematic review. Surgeon 2023; 21:141-151. [PMID: 35715311 DOI: 10.1016/j.surge.2022.04.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 04/28/2022] [Indexed: 11/16/2022]
Abstract
INTRODUCTION The NHS accounts for 5.4% of the UK's total carbon footprint, with the perioperative environment being the most resource hungry aspect of the hospital. The aim of this systematic review was to assimilate the published studies concerning the sustainability of the perioperative environment, focussing on the impact of implemented interventions. METHODS A systematic review was performed using Pubmed, OVID, Embase, Cochrane database of systematic reviews and Medline. Original manuscripts describing interventions aimed at improving operating theatre environmental sustainability were included. RESULTS 675 abstracts were screened with 34 manuscripts included. Studies were divided into broad themes; recycling and waste management, waste reduction, reuse, reprocessing or life cycle analysis, energy and resource reduction and anaesthetic gases. This review summarises the interventions identified and their resulting effects on theatre sustainability. DISCUSSION This systematic review has identified simple, yet highly effective interventions across a variety of themes that can lead to improved environmental sustainability of surgical operating theatres. Combining these interventions will likely result in a synergistic improvement to the environmental impact of surgery.

"Happy to close?" The relationship between surgical experience and incisional hernia rates following abdominal wall closure in colorectal surgery. Colorectal Dis 2023. [PMID: 36965056 DOI: 10.1111/codi.16537] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 02/01/2023] [Accepted: 02/09/2023] [Indexed: 03/27/2023]
Abstract
AIM Incisional hernia (IH) is a common complication of colorectal surgery, affecting up to 30% of patients at 2 years. Given the associated morbidity and high recurrence rates after attempted repair of IH, emphasis should be placed on prevention. There is an association between surgeon volume and outcomes in hernia surgery, yet there is little evidence regarding impact of the seniority of the surgeon performing abdominal wall closure on IH rate. The aim of our study was to assess the rates of IH at 1 year following abdominal wall closure between junior and senior surgeons in patients undergoing elective colorectal surgery. METHODS This was an exploratory analysis of patients who underwent elective surgery for colorectal cancer between 2014-2018 as part of the Hughes Abdominal Repair Trial (HART), a prospective, multicentre randomised control trial comparing abdominal wall closure methods. Grade of surgeon performing abdominal closure was categorised into "trainee" and "consultant" and compared to IH rate at one year. RESULTS A total of 663 patients were included in this retrospective analysis of patients in the HART trial. The rate of IH in patients closed by trainees was 20%, compared to 12% in those closed by consultants (p = <0.001). When comparing closure methods, IH rates were significantly higher in the Hughes closure arm between trainees and consultants (20% vs. 12%, p = 0.032), but not high enough in the mass closure arm to reach statistical significance (21% vs. 13%, p = 0.058). On multivariate analysis, age (p = 0.036, OR: 1.02, 95% CI: 1.00-1.04), Male sex (p = 0.049, OR: 1.61, 95% CI: 1.00-2.59) and closure by a trainee (p = 0.006, OR: 1.85, 95% CI: 1.20-2.85) were identified as risk factors for developing IH. CONCLUSION Patients who undergo abdominal wall closure by a surgeon in training have an increased risk of developing IH when compared to those closed by a consultant. Further work is needed to determine the impact of supervised and unsupervised trainees on IH rates, but abdominal wall closure should be regarded as a training opportunity in its own right.

Abstract
INTRODUCTION Rectal cancer is common with a 60% 5-year survival rate. Treatment usually involves surgery with or without neoadjuvant chemoradiotherapy or adjuvant chemotherapy. Sphincter saving curative treatment can result in debilitating changes to bowel function known as low anterior resection syndrome (LARS). There are currently no clear guidelines on the management of LARS with only limited evidence for different treatment modalities. METHODS AND ANALYSIS Patients who have undergone an anterior resection for rectal cancer in the last 10 years will be approached for the study. The feasibility trial will take place in four centres with a 9-month recruitment window and 12 months follow-up period. The primary objective is to assess the feasibility of recruitment to the POLARiS trial which will be achieved through assessment of recruitment, retainment and follow-up rates as well as the prevalence of major LARS.Feasibility outcomes will be analysed descriptively through the estimation of proportions with confidence intervals. Longitudinal patient reported outcome measures will be analysed according to scoring manuals and presented descriptively with reporting graphically over time. ETHICS AND DISSEMINATION Ethical approval has been granted by Wales REC1; Reference 22/WA/0025. The feasibility study is in the process of set up. The results of the feasibility trial will feed into the design of an expanded, international trial. TRIAL REGISTRATION NUMBER CT05319054.

Abstract
INTRODUCTION Incisional hernia (IH) is a common complication of abdominal surgery affecting between 10% and 20% of patients and is associated with significant morbidity along with cost to the National Health Service. With high recurrence rates following repair, focus must be on prevention of IH rather than cure. There is an increasing evidence that patients at high risk of developing IH may benefit from prophylactic mesh placement during their index operation. With recent controversy surrounding the use of mesh in the UK, however, there is little understanding of whether this intervention would be acceptable to patients. METHODS AND ANALYSIS INVITE is a mixed-methods, cross-sectional study to explore patient perceptions of the use of mesh as prophylaxis to prevent IH. Patients with and without IH who have undergone colorectal surgery between 2017 and 2020 in a single UK health-board will be approached to participate. 120 participants will be asked to complete a questionnaire and a subgroup of 24 participants will be invited to semistructured interviews. The primary outcome is to assess the acceptability of prophylactic mesh to patients. Secondary outcomes include understanding patients' knowledge of IH, and factors that may influence or alter the acceptability of mesh. Questionnaires have been developed using a 5-point Likert scale to allow quantitative analysis. Qualitative analysis of interviews will be conducted using NVivo software and thematic analysis. Data will be presented using the Journal Article Reporting Standards for mixed-methods research. ETHICS AND DISSEMINATION Ethical approval has been granted by REC Wales (22/PR/0678), and the study is currently in setup. All participants will be required to provide informed consent prior to their participation in the study. We plan to report the results of the study in peer-reviewed scientific and medical journals and via presentations at scientific meetings. Results from this study will aid the design of interventional trials using prophylactic mesh. TRIAL REGISTRATION NUMBER NCT05384600.

Abstract
Abstract
Introduction
Incisional Hernia (IH) is a common complication of abdominal surgery. IH is associated with significant morbidity to patients, and costs to the NHS. With no singular intervention demonstrated to bring the rate of IH below 12%, focus is now on pre-operative risk-prediction. High-risk patients may benefit from prophylactic mesh placement during their index operation, however with controversy surrounding the use of mesh, there is no understanding of whether this intervention is acceptable to patients.
Methods
This is a retrospective, single centre mixed-methods cohort study. Patients with and without IH who have undergone colorectal surgery will be approached, along with a smaller cohort of patients about to undergo surgery. Participants will be asked to complete a questionnaire and a sub-set of participants will be invited to semi-structured interviews. The primary objective is to assess the acceptability of prophylactic mesh to patients. Secondary outcomes include understanding patient's views on risk-predictive modelling, and factors that may influence or alter the acceptability of mesh.
Analysis
Questionnaires have been developed using a 5-point Likert scale to allow quantitative analysis. Qualitative analysis of interviews will be conducted using Clarke and Braun's framework of thematic analysis. Data will be presented using the Journal Article Reporting Standards (JARS) for mixed-methods research.
Outcomes
Ethical approval has been granted, and the trial is currently in set-up. Results from this study will be used to inform both in the design and recruitement of patients to future interventional trials using prophylactic mesh in the UK.

Incisional hernia following colorectal cancer surgery according to suture technique: Hughes Abdominal Repair Randomized Trial (HART). Br J Surg 2022; 109:943-950. [PMID: 35979802 PMCID: PMC10364691 DOI: 10.1093/bjs/znac198] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 05/09/2022] [Accepted: 05/13/2022] [Indexed: 11/14/2022]
Abstract
BACKGROUND Incisional hernias cause morbidity and may require further surgery. HART (Hughes Abdominal Repair Trial) assessed the effect of an alternative suture method on the incidence of incisional hernia following colorectal cancer surgery. METHODS A pragmatic multicentre single-blind RCT allocated patients undergoing midline incision for colorectal cancer to either Hughes closure (double far-near-near-far sutures of 1 nylon suture at 2-cm intervals along the fascia combined with conventional mass closure) or the surgeon's standard closure. The primary outcome was the incidence of incisional hernia at 1 year assessed by clinical examination. An intention-to-treat analysis was performed. RESULTS Between August 2014 and February 2018, 802 patients were randomized to either Hughes closure (401) or the standard mass closure group (401). At 1 year after surgery, 672 patients (83.7 per cent) were included in the primary outcome analysis; 50 of 339 patients (14.8 per cent) in the Hughes group and 57 of 333 (17.1 per cent) in the standard closure group had incisional hernia (OR 0.84, 95 per cent c.i. 0.55 to 1.27; P = 0.402). At 2 years, 78 patients (28.7 per cent) in the Hughes repair group and 84 (31.8 per cent) in the standard closure group had incisional hernia (OR 0.86, 0.59 to 1.25; P = 0.429). Adverse events were similar in the two groups, apart from the rate of surgical-site infection, which was higher in the Hughes group (13.2 versus 7.7 per cent; OR 1.82, 1.14 to 2.91; P = 0.011). CONCLUSION The incidence of incisional hernia after colorectal cancer surgery is high. There was no statistical difference in incidence between Hughes closure and mass closure at 1 or 2 years.

Abstract
Abstract
Introduction
Emergency laparotomy (EmLap) is a “life-saving” procedure, but little is known about how “life-changing” it can be. This study aims to establish the impact of EmLap on PROMs and PREMs.
Methods
All surviving patients who had an EmLap from 2016–2019 were included. Eligible patients were invited to complete a postal questionnaire. Responses underwent qualitative and logistical regression analysis.
Results
Response rate was 42.6% (n=310). 11.3% reported that they had not resumed intimacy post-op. Patients were less likely to resume intimacy if they were >80 years (OR 10.500, p0.003), had a return to theatre (OR 5.111, p0.017), IBD diagnosis (OR 5.00, p0.009) or stoma (OR 4.906, p0.003). Patients were more likely to change employment if female (OR 2.858, p0.009), more comorbid (ASA3 OR 5.000, p0.024), had a stoma (OR 4.006, p<0.001), or incisional hernia (OR 4.228, p<0.001). Qualitative analysis revealed deconditioning, lack of employer support, and delays to reconstructive surgery were the main reasons for not returning to work. Qualitative analysis of experience exposed a number of unmet needs: surgical “debrief” and “what to expect” (33.6%), surgical aftercare (25.2%), mental-health support (22.6%) and timely restorative surgery (11.7%). 88.1% felt a specialist nurse would have improved their experience. Patients were more likely to have reported a negative experience if they had benign disease (p0.010).
Conclusion
This is the first study to describe PROMS and PREMS following EmLap, and also to identify patients at risk of poor outcome. It advocates the need for an EmLap specialist nurse to facilitate holistic care.

Research priorities in emergency general surgery (EGS): a modified Delphi approach. World J Emerg Surg 2022; 17:33. [PMID: 35710497 PMCID: PMC9202984 DOI: 10.1186/s13017-022-00432-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 05/24/2022] [Indexed: 11/10/2022] Open
Abstract
Background Emergency general surgery (EGS) patients account for more than one-third of admissions to hospitals in the National Health Service (NHS) in England. The associated mortality of these patients has been quoted as approximately eight times higher than that of elective surgical admissions. This study used a modified Delphi approach to identify research priorities in EGS. The aim was to establish a research agenda using a formal consensus-based approach in an effort to identify questions relevant to EGS that could ultimately guide research to improve outcomes for this cohort. Methods Three rounds were conducted using an electronic questionnaire and involved health care professionals, research personnel, patients and their relatives. In the first round, stakeholders were invited to submit clinical research questions that they felt were priorities for future research. In rounds two and three, participants were asked to score individual questions in order of priority using a 5-point Likert scale. Between rounds, an expert panel analysed results before forwarding questions to subsequent rounds. Results Ninety-two EGS research questions were proposed in Phase 1. Following the first round of prioritisation, forty-seven questions progressed to the final phase. A final list of seventeen research questions were identified from the final round of prioritisation, categorised as condition-specific questions of high interest within general EGS, emergency colorectal surgery, non-technical and health services research. A broad range of research questions were identified including questions on peri-operative strategies, EGS outcomes in older patients, as well as non-technical and technical influences on EGS outcomes. Conclusions Our study provides a consensus delivered framework that should determine the research agenda for future EGS projects. It may also assist setting priorities for research funding and multi-centre collaborative strategies within the academic clinical interest of EGS.

Warmed and humidified insufflation to prevent perioperative hypothermia and improve the quality of recovery in elective laparoscopic colorectal resection patients: a feasibility study for a triple-blind randomized controlled trial. Colorectal Dis 2021; 23:3262-3271.

Abstract
AIM The use of standard CO2 for insufflation during laparoscopic colorectal surgery may be associated with cooling and drying of the peritoneal cavity, contributing to perioperative hypothermia. The aim of this work was the assess the feasibility of a study to compare insufflation of warmed, humidified CO2 (WHCO2) (using HumiGard, Fisher and Paykel Healthcare) with standard measures and its impact on the quality of recovery of surgical patients. METHOD A single-centre, triple-blind, feasibility, randomized controlled trial (RCT) of adults scheduled for planned laparoscopic colorectal surgery. The primary outcome was recruitment. Secondary outcomes included feasibility of blinding, acceptability to patients and suitability of objective measures: patient-reported quality of recovery using a validated questionnaire (QoR-40), patient pain scores and semi-continuous core temperature measurements. RESULTS Thirty-nine participants were randomized to either the WHCO2 group (n = 19) or standard care alone (n = 20). Recruitment to the study was successful and acceptable to patients. Blinding of the surgeons, patients and assessors was effective. Response rates to QoR-40 were high but ceiling effects were observed, indicating that the tool was unsuitable in this population. Fewer patients in the WHCO2 group reported postoperative nausea and vomiting (PONV) at days 1 (53% vs. 65%) and 3 (37% vs. 60%). The median hospital length of stay was 5.5 days in the standard care group and 4 days in the WHCO2 group. CONCLUSION A study of WHCO2 for insufflation in laparoscopic colorectal surgery would be highly acceptable to both patients and researchers. Potential reductions in PONV and hospital length of stay in patients treated with WHCO2 merit further investigation. The design of the full-scale RCT will benefit from this feasibility study.

Abstract
BACKGROUND Anastomotic leakage (AL) is a major complication of colorectal surgery resulting in morbidity, mortality and poorer quality of life. The early diagnosis of AL is challenging due to the poor positive predictive value of tests available and reliance on clinical presentation which may be delayed. The aim of this systematic review was to assess the applicability of peritoneal cytokine levels as an early predictive test of AL in postoperative colorectal cancer patients. METHODS A comprehensive literature search was performed from inception to January 2021, in MEDLINE and EMBASE databases using MeSH and non-MeSH terms in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All studies evaluating peritoneal cytokines in the context of AL were included in this review. RESULTS Two hundred ninety-two abstracts were screened, 30 full manuscripts evaluated, and 12 prospective studies were included. There were 8 peritoneal cytokines evaluated (interleukin [IL]-1β, IL-6, IL-8, IL-10, vascular endothelial growth factor [VEGF], tumour necrosis factor alpha [TNF alpha] and matrix metalloproteinase [MMP]2 and MMP9) between AL and non-AL groups on postoperative day 1. Those that included IL-6 (7 studies), IL-10 (4 studies), TNF alpha (6 studies) and MMP9 (2 studies) were included in the meta-analysis. IL-10 was the only cytokine in the meta-analysis that was significantly (p < 0.05) raised in drain fluid on postoperative day 1 in AL patients. CONCLUSIONS Peritoneal IL-10 was significantly raised on postoperative day 1 in patients who subsequently developed AL. This may be a useful early predictor of AL and aid in an earlier diagnosis for postoperative colorectal patients. The range of cytokines investigated within the literature is limited and from heterogeneous studies which suggests more research is needed.

Abstract
Abstract
Aims
NELA has been instrumental at improving perioperative care and 30–day mortality following emergency laparotomy (EmLap); long-term outcomes and follow-up are less well reported. This study aims to establish the unscheduled and scheduled service use of EmLap patients after discharge.
Methods
This is a single-centre service evaluation. Patients were included if they had an EmLap recorded from 2016-2019 at our local institute and were alive on discharge. Outcomes were 30-day readmission rate and outpatient follow-up.
Results
944 patients were included. 11.9% re-presented to the surgical department within 30-days; 58.0% of these needed readmissions. The most common causes for re-presentation (n = 112) were management of a wound issue (15.2%), ongoing pain without evidence of complication (10.7%) and ongoing intra-abdominal sepsis (9.8%).
1-year survival was 81.4%. Of these (n = 856); 74.3% were invited to outpatients; DNA rate was 8.8%, with only 67.8% of patients having a follow-up review. Median time to follow up was 9 weeks. Patients were more likely to be invited for outpatient review if they had a new stoma (OR 2.56, 95% CI 1.81 – 3.56), and less likely if adhesiolysis was the primary procedure (OR 0.55, 95% 0.39-0.76).
Patients who failed to attend an appointment were significantly younger (median age 53 vs. 60 years, p = 0.0033) and from more deprived areas (average WIMD 673.6 vs 977.3, p = 0.002).
Conclusion
This study demonstrates higher levels of unscheduled care and lower levels of scheduled care than expected. Care standards should be extended beyond the 30-day milestone to fully appreciate the morbidity associated from EmLap.

Abstract
BACKGROUND The 5-year survival rate for bowel cancer in Wales is poor and lags behind the rest of the UK. The aim of the pilot phase of the Moondance Schools Initiative was to develop, deliver and assess a bowel cancer learning module for secondary school students in South Wales. Ultimately, we aim to introduce this programme into the National Curriculum across Wales. METHODS Two programmes regarding bowel cancer and screening were designed and delivered to a cohort of secondary school pupils in South Wales. This involved interactive teaching with patients and clinicians, practical sessions and live-streamed videos of bowel cancer surgery. Feedback regarding the events and bowel screening was collected from students and their families. RESULTS The programmes were delivered to 185 secondary school students and feedback was extremely positive. The students delivered a live event at the end of the programme to demonstrate their learning to their families and invited guests. Feedback from family members revealed that 100% of respondents were more likely to take a bowel screening test as a result of attending the event. CONCLUSION This project established that a pilot to create young bowel screening ambassadors is feasible and was positively received by students, their families and the local community. Future work will disseminate the programme further and correlate changes in bowel screening participation in the local area as a result of these events.

Can we detect fibrofatty band in patients with bowel obstruction on CT scan? BJR Case Rep 2021; 7:20210016. [PMID: 35136623 PMCID: PMC8803246 DOI: 10.1259/bjrcr.20210016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 05/09/2021] [Accepted: 05/21/2021] [Indexed: 11/06/2022] Open
Abstract
Fibrofatty bands are composed of adipose tissue and connective tissue and can tangle around the bowel and caused intestinal obstruction. Currently, there is a lack of radiological teaching or guidance on how to identify fibrofatty band in patients with bowel obstruction. The true incidence of fibrofatty band-induced bowel obstruction is likely to have been overlooked. We present a case series of patients with fibrofatty bands with different features and aim to highlight the key radiological findings that may help in the radiological diagnosis. We advocate that these features should be incorporated into the current algorithm for radiologist when assessing scan images of patients with intestinal obstruction.

Abstract
AIM The COVID-19 pandemic led to widespread disruption of colorectal cancer services during 2020. Established cancer referral pathways were modified in response to reduced diagnostic availability. The aim of this paper is to assess the impact of COVID-19 on colorectal cancer referral, presentation and stage. METHODS This was a single centre, retrospective cohort study performed at a tertiary referral centre. Patients diagnosed and managed with colorectal adenocarcinoma between January and December 2020 were compared with patients from 2018 and 2019 in terms of demographics, mode of presentation and pathological cancer staging. RESULTS In all, 272 patients were diagnosed with colorectal adenocarcinoma during 2020 compared with 282 in 2019 and 257 in 2018. Patients in all years were comparable for age, gender and tumour location (P > 0.05). There was a significant decrease in urgent suspected cancer referrals, diagnostic colonoscopy and radiological imaging performed between March and June 2020 compared with previous years. More patients presented as emergencies (P = 0.03) with increased rates of large bowel obstruction in 2020 compared with 2018-2019 (P = 0.01). The distribution of TNM grade was similar across the 3 years but more T4 cancers were diagnosed in 2020 versus 2018-2019 (P = 0.03). CONCLUSION This study demonstrates that a relatively short-term impact on the colorectal cancer referral pathway can have significant consequences on patient presentation leading to higher risk emergency presentation and surgery at a more advanced stage. It is therefore critical that efforts are made to make this pathway more robust to minimize the impact of other future adverse events and to consolidate the benefits of earlier diagnosis and treatment.

Abstract
Abstract
Introduction
To evaluate the medical school undergraduate curriculum on faecal incontinence (FI) and develop an educational tool to improve the teaching on the subject.
Method
Qualitative analysis of literature research and data collected from medical students via emails, questionnaires and focused group discussions.
Result
FI has not been implanted into the undergraduate curriculum 12,13 and there are variations in teaching on the topic in different medical schools. n= 111 medical students at Cardiff University responded to the survey. FI was reported to be overlooked compared to other types of bowel dysfunction. 38 students reported to have teaching on bowel incontinence, whereas 64 and 74 students had teaching on diarrhoea and constipation respectively. 77% of medical students would like more teaching on bowel incontinence. 9 students participated in a focused group discussion. An interactive e-learning module from Xerte was created based on the students' suggestions and were trialed by a separate cohort of students (n=20). All 20 students showed significant improvement of students' confidence in faecal incontinence (p <= 2.132e∧-6) after completing the e-learning module.
Conclusion
We recommend introducing the educational resource into the undergraduate curriculum of Cardiff University medical school, especially targeting the clinical year, a clear guidance for FI should be published by the relevant postgraduate healthcare faculties and consider assessing at which stage of the postgraduate training should FI be taught.
Take-home message
Baseline knowledge of FI is poor. Lack of content in medical school curriculum and E learning modules potentially useful adjuncts.

Abstract
INTRODUCTION The COVID-19 pandemic stimulated a national lockdown in the UK. The public were advised to avoid unnecessary hospital attendances and health professionals were advised to avoid aerosol-generating procedures wherever possible. The authors hypothesised that these measures would result in a reduction in the number of patients presenting to hospital with acute appendicitis and alter treatment choices. METHODS A multicentred, prospective observational study was undertaken during April 2020 to identify adults treated for acute appendicitis. Searches of operative and radiological records were performed to identify patients treated during April 2018 and April 2019 for comparison. RESULTS A total of 190 patients were treated for acute appendicitis pre-lockdown compared with 64 patients treated during lockdown. Patients treated during the pandemic were more likely to have a higher American Society of Anesthesiology (ASA) score (p = 0.049) and to have delayed their presentation to hospital (2 versus 3 days, p = 0.03). During the lockdown, the use of computed tomography (CT) increased from 36.3% to 85.9% (p < 0.001), the use of an antibiotic-only approach increased from 6.2% to 40.6% (p < 0.001) and the rate of laparoscopic appendicectomy reduced from 85.3% to 17.2% (p < 0.001). The negative appendicectomy rate decreased from 21.7% to 7.1% during lockdown (p < 0.001). CONCLUSIONS The COVID-19 lockdown was associated with a decreased incidence of acute appendicitis and a significant shift in the management approach. The increased use of CT allows the identification of simple appendicitis for conservative treatment and decreases the negative appendicectomy rate.

Abstract
Background The COVID-19 global pandemic has resulted in a plethora of guidance and opinion from surgical societies. A controversial area concerns the safety of surgically created smoke and the perceived potential higher risk in laparoscopic surgery. Methods The limited published evidence was analysed in combination with expert opinion. A review was undertaken of the novel coronavirus with regards to its hazards within surgical smoke and the procedures that could mitigate the potential risks to healthcare staff. Results Using existing knowledge of surgical smoke, a theoretical risk of virus transmission exists. Best practice should consider the operating room set-up, patient movement and operating theatre equipment when producing a COVID-19 operating protocol. The choice of energy device can affect the smoke produced, and surgeons should manage the pneumoperitoneum meticulously during laparoscopic surgery. Devices to remove surgical smoke, including extractors, filters and non-filter devices, are discussed in detail. Conclusion There is not enough evidence to quantify the risks of COVID-19 transmission in surgical smoke. However, steps can be undertaken to manage the potential hazards. The advantages of minimally invasive surgery may not need to be sacrificed in the current crisis.

Association between preadmission frailty and care level at discharge in older adults undergoing emergency laparotomy. Br J Surg 2020; 107:218-226.

Abstract
Abstract
Background
Older adults undergoing emergency abdominal surgery have significantly poorer outcomes than younger adults. For those who survive, the level of care required on discharge from hospital is unknown and such information could guide decision-making. The ELF (Emergency Laparotomy and Frailty) study aimed to determine whether preoperative frailty in older adults was associated with increased dependence at the time of discharge.
Methods
The ELF study was a UK-wide multicentre prospective cohort study of older patients (65 years or more) undergoing emergency laparotomy during March and June 2017. The objective was to establish whether preoperative frailty was associated with increased care level at discharge compared with preoperative care level. The analysis used a multilevel logistic regression adjusted for preadmission frailty, patient age, sex and care level.
Results
A total of 934 patients were included from 49 hospitals. Mean(s.d.) age was 76·2(6·8) years, with 57·6 per cent women; 20·2 per cent were frail. Some 37·4 per cent of older adults had an increased care level at discharge. Increasing frailty was associated with increased discharge care level, with greater predictive power than age. The adjusted odds ratio for an increase in care level was 4·48 (95 per cent c.i. 2·03 to 9·91) for apparently vulnerable patients (Clinical Frailty Score (CFS) 4), 5·94 (2·54 to 13·90) for those mildly frail (CFS 5) and 7·88 (2·97 to 20·79) for those moderately or severely frail (CFS 6 or 7), compared with patients who were fit.
Conclusion
Over 37 per cent of older adults undergoing emergency laparotomy required increased care at discharge. Frailty scoring was a significant predictor, and should be integrated into all acute surgical units to aid shared decision-making and discharge planning.

Altered N-methyl D-aspartate receptor subunit expression causes changes to the circadian clock and cell phenotype in osteoarthritic chondrocytes. Osteoarthritis Cartilage 2018; 26:1518-1530.

Abstract
UNLABELLED The chondrocyte circadian clock is altered in osteoarthritis. This change is implicated in the disease-associated changes in chondrocyte phenotype and cartilage loss. Why the clock is changed is unknown. N-methyl-D-aspartate receptors (NMDAR) are critical for regulating the hypothalamic clock. Chondrocytes also express NMDAR and the type of NMDAR subunits expressed changes in osteoarthritis. OBJECTIVE To determine if NMDAR regulate the chondrocyte clock and phenotype. DESIGN Chondrocytes isolated from macroscopically-normal (MN) and osteoarthritic human cartilage were treated with NMDAR antagonists or transfected with GRIN2A or GRIN2B-targetting siRNA. H5 chondrocytes were transfected with GluN2B-expression plasmids. Clock genes and chondrocyte phenotypic markers were measured by RT-qPCR. RESULTS PER2 amplitude was higher and BMAL1 amplitude lower in osteoarthritic compared to MN chondrocytes. In osteoarthritic chondrocytes, NMDAR inhibition restored PER2 and BMAL1 expression to levels similar to MN chondrocytes, and resulted in reduced MMP13 and COL10A1. Paradoxically, NMDAR inhibition in MN chondrocytes resulted in increased PER2, decreased BMAL1 and increased MMP13 and COL10A1. Osteoarthritic, but not MN chondrocytes expressed GluN2B NMDAR subunits. GluN2B knockdown in osteoarthritic chondrocytes restored expression of circadian clock components and phenotypic markers to levels similar to MN chondrocytes. Ectopic expression of GluN2B resulted in reduced BMAL1, increased PER2 and altered SOX9, RUNX2 and MMP13 expression. Knockdown of PER2 mitigated the effects of GluN2B on SOX9 and MMP13. CONCLUSIONS NMDAR regulate the chondrocyte clock and phenotype suggesting NMDAR may also regulate clocks in other peripheral tissues. GluN2B expression in osteoarthritis may contribute to pathology by altering the chondrocyte clock.

Abstract
OBJECTIVES Incisional hernias are common complications of midline abdominal closure. The 'Hughes Repair' combines a standard mass closure with a series of horizontal and two vertical mattress sutures within a single suture. There is evidence to suggest this technique is as effective as mesh repair for the operative management of incisional hernias; however, no trials have compared Hughes repair with standard mass closure for the prevention of incisional hernia formation. This paper aims to test the feasibility of running a randomised controlled trial of a comparison of abdominal wall closure methods following midline incisional surgery for colorectal cancer, in preparation to a definitive randomised controlled trial. DESIGN AND SETTING A feasibility trial (with 1:1 randomisation) conducted perioperatively during colorectal cancer surgery. PARTICIPANTS Patients undergoing midline incisional surgery for resection of colorectal cancer. INTERVENTIONS Comparison of two suture techniques (Hughes repair or standard mass closure) for the closure of the midline abdominal wound following surgery for colorectal cancer. PRIMARY AND SECONDARY OUTCOMES A 30-patient feasibility trial assessed recruitment, randomisation, deliverability and early safety of the surgical techniques used. RESULTS A total of 30 patients were randomised from 43 patients recruited and consented, over a 5-month period. 14 and 16 patients were randomised to arms A and B, respectively. There was one superficial surgical site infection (SSI) and two organ space SSIs reported in arm A, and two superficial SSIs and one complete wound dehiscence in arm B. There were no suspected unexpected serious adverse reactions reported in either arm. Independent data monitoring committee found no early safety concerns. CONCLUSIONS The feasibility trial found no early safety concerns and demonstrated that the trial was acceptable to patients. Progression to the pilot and main phases of the trial has now commenced following approval by the independent data monitoring committee. TRIAL REGISTRATION NUMBER ISRCTN 25616490.

Abstract
PURPOSE Developments in surgical techniques and neoadjuvant treatment have enabled an increasing proportion of patients with rectal cancer to undergo sphincter-sparing resections. The avoidance of a permanent stoma can come at the cost of poor bowel function which can significantly impact patients' quality of life. The objective of this study was to identify the incidence and risk factors for the development of bowel dysfunction following rectal cancer surgery. METHODS Patients undergoing anterior resection for rectal cancer between January 2009 and January 2015 were identified from a rectal cancer database at a single centre. All patients who had bowel continuity restored and underwent curative resection were sent a validated low anterior resection syndrome (LARS) questionnaire. Pre-, inter- and postoperative factors were compared between patients with major LARS and those with minor or no LARS using conditional logistic regression. RESULTS There was an 80% response rate (n = 68). Thirty-eight patients (56%) had major LARS symptoms. Neoadjuvant radiotherapy, predominantly long-course chemoradiotherapy (LCCRT), was an independent risk factor for development of major LARS symptoms, while restoration of bowel continuity within 6 months was protective. CONCLUSIONS The use of neoadjuvant radiotherapy (LCCRT) and timing of stoma reversal are risk factors for the development of severe bowel dysfunction. The potential for long-term poor functional results after LCCRT should be discussed with patients and form a part of the decision-making in individual treatment plans. The timing of the ileostomy closure, where safe and feasible, should be performed within 6 months to improve outcome.

Abstract
Background Incisional hernias are common complications of midline closure following abdominal surgery and cause significant morbidity, impaired quality of life and increased health care costs. The ‘Hughes Repair’ combines a standard mass closure with a series of horizontal and two vertical mattress sutures within a single suture. This theoretically distributes the load along the incision length as well as across it. There is evidence to suggest that this technique is as effective as mesh repair for the operative management of incisional hernias; however, no trials have compared the Hughes Repair with standard mass closure for the prevention of incisional hernia formation following a midline incision. Methods/design This is a 1:1 randomised controlled trial comparing two suture techniques for the closure of the midline abdominal wound following surgery for colorectal cancer. Full ethical approval has been gained (Wales REC 3, MREC 12/WA/0374). Eight hundred patients will be randomised from approximately 20 general surgical units within the United Kingdom. Patients undergoing open or laparoscopic (more than a 5-cm midline incision) surgery for colorectal cancer, elective or emergency, are eligible. Patients under the age of 18 years, those having mesh inserted or undergoing musculofascial flap closure of the perineal defect in abdominoperineal wound closure, and those unable to give informed consent will be excluded. Patients will be randomised intraoperatively to either the Hughes Repair or standard mass closure. The primary outcome measure is the incidence of incisional hernias at 1 year as assessed by standardised clinical examination. The secondary outcomes include quality of life patient-reported outcome measures, cost-utility analysis, incidence of complete abdominal wound dehiscence and C-POSSUM scores. The incidence of incisional hernia at 1 year, assessed by computerised tomography, will form a tertiary outcome. Discussion A feasibility phase has been completed. The results of the study will be used to inform current and future practice and potentially reduce the risk of incisional hernia formation following midline incisions. Trial registration Trial Registration Number: ISRCTN 25616490. Registered on 1 January 2012.

Systematic Review and Meta-Regression of Factors Affecting Midline Incisional Hernia Rates: Analysis of 14,618 Patients. PLoS One 2015; 10:e0138745.

Abstract
BACKGROUND The incidence of incisional hernias (IHs) following midline abdominal incisions is difficult to estimate. Furthermore recent analyses have reported inconsistent findings on the superiority of absorbable versus non-absorbable sutures. OBJECTIVE To estimate the mean IH rate following midline laparotomy from the published literature, to identify variables that predict IH rates and to analyse whether the type of suture (absorbable versus non-absorbable) affects IH rates. METHODS We undertook a systematic review according to PRISMA guidelines. We sought randomised trials and observational studies including patients undergoing midline incisions with standard suture closure. Papers describing two or more arms suitable for inclusion had data abstracted independently for each arm. RESULTS Fifty-six papers, describing 83 separate groups comprising 14,618 patients, met the inclusion criteria. The prevalence of IHs after midline incision was 12.8% (range: 0 to 35.6%) at a weighted mean of 23.7 months. The estimated risk of undergoing IH repair after midline laparotomy was 5.2%. Two meta-regression analyses (A and B) each identified seven characteristics associated with increased IH rate: one patient variable (higher age), two surgical variables (surgery for AAA and either surgery for obesity surgery (model A) or using an upper midline incision (model B)), two inclusion criteria (including patients with previous laparotomies and those with previous IHs), and two circumstantial variables (later year of publication and specifying an exact significance level). There was no significant difference in IH rate between absorbable and non-absorbable sutures either alone or in conjunction with either regression analysis. CONCLUSIONS The IH rate estimated by pooling the published literature is 12.8% after about two years. Seven factors account for the large variation in IH rates across groups. However there is no evidence that suture type has an intrinsic effect on IH rates.

Abstract
BACKGROUND Resident surgeons have been identified as a risk factor for worse outcome after appendectomy. The context of grade of resident and impact of supervision require further investigation. The objective of this study was to determine whether grade and supervision level of resident-performed appendectomy affects patient outcome. METHODS A multicenter, prospective cohort study was performed for consecutive patients undergoing appendectomy during May and June 2013. The primary endpoint for this analysis was the 30-day adverse event rate. Supervision was defined as resident-performed appendectomy with an attending scrubbed. Multivariable binary logistic regression was used to take into account case mix and produce adjusted odds ratios (OR). RESULTS From 2,867 appendectomies, 87% were performed by residents, and 72% were performed unsupervised. Residents operated on significantly younger patients with lower American Society of Anesthesiologists scores. Although wound infection rates were similar between attendings, and senior and junior residents (4.1%, 3.8%, 3.4% respectively; P = .486), pelvic abscess rate was greater for attendings (5.2%, 2.7%, 2.4%; P = .045). In adjusted models, supervised senior, supervised junior, and unsupervised junior residents showed no difference in 30-day adverse event rates compared with attendings (OR, 1.07 [P = .834], 0.93 [P = .773], and 0.83 [P = .264] respectively); unsupervised senior residents had a lesser rate of adverse events (OR, 0.71; P = .045). All resident groups showed no difference for rates of histopathologically normal appendectomy compared with attendings. CONCLUSION Resident-performed appendectomy does not worsen patient outcomes. These findings support independent resident operating rights for selected cases. The system relies on mutual credentialing of competency between residents and supervising attendings.

Abstract
BACKGROUND The aim was to investigate quality of life, sexual, fecal, and urinary function in females undergoing restorative proctocolectomy (RPC). METHODS A prospective case-control study was performed in two tertiary centers. Controls were females with ulcerative colitis, without a stoma or RPC. Validated questionnaires (SF-36, Female sexual function index, King's questionnaire, and the Wexner scale) were administered in the outpatient setting. Pearson chi(2), t-test, and Mann-Whitney U-tests were used to assess significance. RESULTS A total of 255 females were identified and 49% (n = 124) recruited. In all, 109 patients fulfilled the inclusion criteria: 55 (50.5%) inflammatory bowel disease (IBD); 54 (49.5%) RPC. The mean age of RPC patients was 41.8 years (± 12.7 SD) vs. 43.8 years (± 15.8) for IBD (P = 0.491). RPC females with urinary symptoms (urgency, frequency, or incontinence) were 10 years younger than IBD (RPC mean age 37.6 ± 7.3 years vs. IBD 47.4 ± 13.5; P = 0.044). Urgency in fecal function was experienced by more IBD patients (IBD 75.0% vs. RPC 47.9%; P = 0.006), although RPC patients had increased day (P < 0.001) and night bowel frequency (P < 0.001) and were more likely to experience night seepage (P = 0.001). RPC females who had a vaginal delivery (VD) were more likely to have day seepage (P = 0.046) and require pads (P = 0.026) than RPC females who had not undergone VD. There was no significant difference in sexual function. CONCLUSIONS RPC may adversely impact urinary function in female patients over time. Bowel frequency, seepage, and pad usage are increased following RPC and function may be worse following VD. RPC does not adversely affect overall sexual function.

The role of peptides and receptors of the calcitonin family in the regulation of bone metabolism. Bone 2008; 43:813-8.

Abstract
The 'calcitonin family' is a group of peptide hormones that share structural similarities with calcitonin, and includes calcitonin gene-related peptide (CGRP), amylin, adrenomedullin and adrenomedullin 2 (intermedin). These hormones are produced by different tissues, with calcitonin being produced in thyroid C cells, alphaCGRP predominantly in neural tissue, amylin in beta-islet cells of the pancreas and adrenomedullin in many tissues and cell types. Bone appears to be a common target for all the peptides of the calcitonin family, although the specific bone effects of the peptides vary. Administration of calcitonin produces rapid lowering of serum calcium levels, mainly through inhibition of bone resorption by osteoclasts. In vitro and in a number of animal experimental models, amylin and CGRP are also effective in inhibiting osteoclast activity and bone resorption. Amylin, adrenomedullin and CGRP can also affect cells of the osteoblast lineage, inducing osteoblast proliferation and promoting bone formation. Receptors for the peptides of the calcitonin family are formed by heterodimerization of the calcitonin receptor (CTR) or calcitonin receptor-like receptor (CLR) with receptor activity modifying proteins (RAMPs). Although the different combinations of these proteins create receptors with distinct ligand specificities, there is a degree of cross-reactivity and the receptors are able to bind other ligands from the family, usually with lower affinity. Analysis of the expression of the receptors for the calcitonin family in 16 samples of human osteoblasts showed high levels of CLR and RAMP1, low levels of RAMP2 and no expression of RAMP3 or CTR. Recent studies of the bone phenotype of knockout animals lacking the calcitonin, alphaCGRP or amylin gene indicated that in this experimental system the main physiological role of amylin in bone is the inhibition of bone resorption, that of CGRP is the activation of bone formation, while calcitonin, unexpectedly appears to be inhibiting bone formation without affecting bone resorption. Further investigations will be required to determine the mechanisms of action of calcitonin peptides in bone and their significance to human bone physiology.

Abstract
Objectives:Magnetic resonance imaging (MRI) bone oedema is an important predictor of bone erosion in rheumatoid arthritis (RA). This study aimed to determine the cellular components of MRI bone oedema, and clarify the relationship between bone erosion and MRI bone oedema.Methods:Twenty-eight bones from 11 patients with RA undergoing orthopaedic surgery were analysed by quantitative and semi-quantitative immunohistochemistry. Pre-operative contrast-enhanced MRI scans were analysed for bone oedema.Results:The density of osteoclasts was higher in those samples with MRI bone oedema than those without MRI bone oedema (p = 0.01). Other cells identified within bone marrow included macrophages and plasma cells, and these were more numerous in samples with MRI bone oedema (p = 0.02 and 0.05 respectively). B cells were present in lower numbers, but B cell aggregates were identified in some samples with MRI bone oedema. There was a trend to increased RANKL expression in samples with MRI bone oedema (p = 0.09). Expression of RANKL correlated with the number of osteoclasts (r = 0.592, p = 0.004).Conclusions:The increased number of osteoclasts and RANKL expression in samples with MRI bone oedema supports the hypothesis that bone erosion in RA occurs through activation of local bone resorption mechanisms within subchondral bone as well as through synovial invasion into bone.

Abstract
The definition of indications for allogeneic SCT in children with high-risk (HR) ALL in the first remission or after the first or subsequent relapse depends on biological features, response to treatment and survival after chemotherapy alone. As the results of frontline and relapse protocols are improving over time, there is a strong need for prospective SCT trials, ensuring a well-standardized procedure regarding all relevant components that are potentially responsible for heterogeneity in post-SCT outcome. Therefore, in 2003, the ALL-BFM and the ALL-REZ BFM Study Group initiated a prospective, international, multicenter trial (ALL-SCT-BFM 2003). This trial will now be extended to a larger consortium, trial ALL-SCT-BFM-international (ALL-SCT-BFMi). Strict rules define HLA-typing, donor selection, conditioning regimen, GvHD prophylaxis and therapy as well as standards of supportive care to reduce treatment-related mortality and establish an early GVL effect. Moreover, comprehensive and closely reviewed documentation and serious adverse event reporting shall ensure high study quality. Case-by-case discussions of any fatal or critical course during annual meetings will improve the culture of failure management and lead to modifications of guidelines of supportive care. Finally, the results of these prospective trials will determine the current potential of the different SCT procedures in HR or relapsed childhood ALL.

Abstract
BACKGROUND Artificial bowel sphincter (ABS) and dynamic graciloplasty (DG) are surgical treatments for faecal incontinence (FI). FI may affect quality of life (QOL) so severely that patients are often willing to consider a permanent end stoma (ES). It is unclear which is the more cost-effective strategy. METHOD Probability estimates for patients with FI were obtained from published data (ABS, n = 319; DG, n = 301), supplemented by expert opinion. The primary outcome was quality-adjusted life years (QALYs) gained from each strategy. Factors considered were the risk of failure of the primary and redo operation and the consequent risk of permanent stoma. Results were assessed as incremental cost-effectiveness ratio (ICER). RESULTS Over the 5-year time horizon, ES gave a QALY gain of 3.45 for 16,280 pounds sterling, giving an ICER of 4719 pounds sterling/QALY. ABS produced a gain of 4.38 QALYs for 23,569 pounds sterling, giving an ICER of 5387 pounds sterling/QALY. DG produced a gain of 4.00 QALYs for 25,035 pounds sterling, giving an ICER of 6257 pounds sterling/QALY. With the willingness-to-pay threshold set at 30,000 pounds sterling/QALY, ES was the most cost-effective intervention. The ABS was most cost-effective after 10 years. CONCLUSION All three procedures were found to be cost-effective. The ES was most cost-effective over 5 years, while the ABS was most cost-effective in excess of 10. DG maybe considered as an alternative in specialist centres.
