Abstract

Introduction As a result of improving survival rates, the adverse consequences of rectal cancer surgery are becoming increasingly recognised. Low anterior resection syndrome (LARS) is one such consequence and describes a constellation of bowel symptoms after rectal cancer surgery which includes urgency, faecal incontinence, stool clustering and incomplete evacuation. LARS has a significant adverse impact on quality of life (QoL) and symptoms are present in up to 75% of patients in the first year after surgery. Despite this, little is known about the natural history and there is poor evidence to support current treatment options.Methods and analysis The objectives of POLARiS are to explore the natural history of LARS and to evaluate the clinical and cost-effectiveness of transanal irrigation (TAI) or sacral neuromodulation (SNM) compared with optimised conservative management (OCM) for people with major LARS.POLARiS is a prospective, international, open-label, multi-arm, phase 3 randomised superiority trial within a cohort design, with internal pilot phase, qualitative sub-study, process evaluation and economic evaluation. Approximately 1500 adult participants from UK hospitals and 500 from Australian hospitals who have undergone a high or low anterior resection for colorectal cancer in the last 10 years will be recruited into the cohort. Six-hundred participants from the UK and 200 participants from Australia, with major LARS symptoms, defined as a LARS score of ≥30, will be recruited to the randomised controlled trial (RCT) element. Participants entering the RCT will be randomised between OCM, TAI or SNM, all with equal allocation ratios.Cohort and RCT participants will be followed up for a 24-month period, completing a series of questionnaires measuring LARS symptoms and QoL, as well as clinical review for those in the RCT. A process evaluation, qualitative sub-study and economic evaluation will also be conducted.The primary outcome measure of the POLARiS cohort and RCT is the LARS score up to 24 months post-registration/randomisation. Analyses of the RCT will be conducted on an intention-to-treat basis. Comparative effectiveness analyses for each endpoint will consist of two pairwise treatment comparisons: TAI versus OCM and SNM versus OCM. Secondary outcomes include health-related QoL, adverse events, treatment compliance and cost-effectiveness (up to 24 months post-registration/randomisation).Ethics and dissemination Ethical approval has been granted by Wales REC 4 (reference: 23/WA/0171) in the UK and Sydney Local Health District HREC (reference: 2023/ETH00749) in Australia. The results of this trial will be disseminated to participants on request and published on completion of the trial in a peer-reviewed journal and at international conferences.Trial registration number ISRCTN12834598; ACTRN12623001166662.

Abstract

Objectives To assess the current state-of-the-art in deep learning methods applied to pre-operative radiologic staging of colorectal cancer lymph node metastasis. Specifically, by evaluating the data, methodology and validation of existing work, as well as the current use of explainable AI in this fast-moving domain.Design Scoping review.Data sources Academic databases MEDLINE, Embase, Scopus, IEEE Xplore, Web of Science and Google Scholar were searched with a date range of 1 January 2018 to 1 February 2024.Eligibility criteria Includes any English language research articles or conference papers published since 2018 which have applied deep learning methods for feature extraction and classification of colorectal cancer lymph nodes on pre-operative radiologic imaging.Data extraction and synthesis Key results and characteristics for each included study were extracted using a shared template. A narrative synthesis was then conducted to qualitatively integrate and interpret these findings.Results This scoping review covers 13 studies which met the inclusion criteria. The deep learning methods had an area under the curve score of 0.856 (0.796 to 0.916) for patient-level lymph node diagnosis and 0.904 (0.841 to 0.967) for individual lymph node assessment, given with a 95% confidence interval. Most studies have fundamental limitations including unrepresentative data, inadequate methodology, poor model validation and limited explainability techniques.Conclusions Deep learning methods have demonstrated the potential for accurately diagnosing colorectal cancer lymph nodes using pre-operative radiologic imaging. However, several methodological and validation flaws such as selection bias and lack of external validation make it difficult to trust the results. This review has uncovered a research gap for robust, representative and explainable deep learning methods that are end-to-end from automatic lymph node detection to the diagnosis of lymph node metastasis.

Abstract

Abstract Background No residual disease (CC 0) following cytoreductive surgery is pivotal for the prognosis of women with advanced stage epithelial ovarian cancer (EOC). Improving CC 0 resection rates without increasing morbidity and no delay in subsequent chemotherapy favors a better outcome in these women. Prerequisites to facilitate this surgical paradigm shift and subsequent ramifications need to be addressed. This quality improvement study assessed 559 women with advanced EOC who had cytoreductive surgery between January 2014 and December 2019 in our tertiary referral centre. Following implementation of the Enhanced Recovery After Surgery (ERAS) pathway and prehabilitation protocols, the surgical management paradigm in advanced EOC patients shifted towards maximal surgical effort cytoreduction in 2016. Surgical outcome parameters before, during, and after this paradigm shift were compared. The primary outcome measure was residual disease (RD). The secondary outcome parameters were postoperative morbidity, operative time (OT), length of stay (LOS) and progression-free-survival (PFS). Results R0 resection rate in patients with advanced EOC increased from 57.3% to 74.4% after the paradigm shift in surgical management whilst peri-operative morbidity and delays in adjuvant chemotherapy were unchanged. The mean OT increased from 133 + 55 min to 197 + 85 min, and postoperative high dependency/intensive care unit (HDU/ICU) admissions increased from 8.1% to 33.1%. The subsequent mean LOS increased from 7.0 + 2.6 to 8.4 + 4.9 days. The median PFS was 33 months. There was no difference for PFS in the three time frames but a trend towards improvement was observed. Conclusions Improved CC 0 surgical cytoreduction rates without compromising morbidity in advanced EOC is achievable owing to the right conditions. Maximal effort cytoreductive surgery should solely be carried out in high output tertiary referral centres due to the associated substantial prerequisites and ramifications.

Abstract

Introduction The empty pelvis syndrome is a significant source of morbidity following pelvic exenteration surgery. It remains poorly defined with research in this field being heterogeneous and of low quality. Furthermore, there has been minimal engagement with patient representatives following pelvic exenteration with respect to the empty pelvic syndrome. ‘PelvEx—Beating the empty pelvis syndrome’ aims to engage both patient representatives and healthcare professionals to achieve an international consensus on a core outcome set, pathophysiology and mitigation of the empty pelvis syndrome.Methods and analysis A modified-Delphi approach will be followed with a three-stage study design. First, statements will be longlisted using a recent systematic review, healthcare professional event, patient and public engagement, and Delphi piloting. Second, statements will be shortlisted using up to three rounds of online modified Delphi. Third, statements will be confirmed and instruments for measurable statements selected using a virtual patient-representative consensus meeting, and finally a face-to-face healthcare professional consensus meeting.Ethics and dissemination The University of Southampton Faculty of Medicine ethics committee has approved this protocol, which is registered as a study with the Core Outcome Measures in Effectiveness Trials Initiative. Publication of this study will increase the potential for comparative research to further understanding and prevent the empty pelvis syndrome.Trial registration number NCT05683795.

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

The COVID-19 pandemic created an urgent need for high-quality rapid research. One clinical challenge was how to minimise the risk of transmission in the hospital setting. The CLEAN study conducted a rapid evaluation of the potential utility of a spray-based disinfectant in a hospital setting. The study was undertaken between December 2020 and March 2021 and involved the implementation of the spray in 10 different clinical areas in one UK teaching hospital. A mixed-methods approach was adopted (including observations, surveys, and qualitative interviews) informed by the theories for understanding the implementation of new healthcare technologies. The evaluation found that while the spray had a number of perceived benefits when added to existing disinfection processes, other factors limited its potential utility. These findings informed a number of recommendations for future adoption within hospital settings. This paper describes and reflects on the rapid methodology that allowed us to undertake the study and deliver results in a short space of time. We experienced a number of pressures during set-up and fieldwork due to the challenging conditions caused by the pandemic, and the methodological approach had to evolve throughout the study because of the changing clinical context. The involvement of clinicians from the research setting as full members of the research team was key to the rapid delivery of the research. They provided an essential link to the implementation environment, and their experiential knowledge of the setting added an important perspective to the analysis. Balancing their involvement with their clinical roles was challenging, however, as was coordinating a large and diverse team of interviewers in such a short space of time. Overall, the study highlighted the value of rapid research to inform urgent healthcare decisions in a pandemic. Although our experience suggests that conducting such research requires some practical and methodological trade-offs, we found that there were also numerous benefits of using rapid methods and identified various opportunities to ensure their robustness.

Abstract

Women raise children within cultural ideologies that enforce gendered standards for caregiving. In market‐driven societies, working mothers face the 'intensive mothering ideology', which demands self‐sacrifice for children while promoting self‐interest at work. Fathers are primarily framed as breadwinners. We know little about how ethnically and racially diverse, low‐SES mothers construct ideas of good and bad parenting. In this study, we examined Dominican, African American and Mexican US‐based mothers' perspectives on ideal qualities of mothers and fathers (N = 193, daughters = 51.3%, MAge = 26.27). Using semantic and latent coding, we analysed the content and framing of mothers' responses, which fell into 28 themes, emphasising idealised parenting as providing basic needs, emotional support, education and embodying desired traits. Our latent analyses captured the frequencies of qualities mentioned by mothers, whether they centered children or parents, the presence or absence of qualities and performed actions or embodied characteristics. Our findings highlight the social constructions of mothering and fathering and offer a foundation for future mixed‐methods research. [ABSTRACT FROM AUTHOR]

Abstract

The 2018 General Education Program (GEP) has significantly reformed the Vietnamese education system. One of its requirements is for students to respect cultural diversity. This article aims at examining English as a Foreign Language (EFL) teachers' perception and practices toward teaching socio-cultural contents (SCC) presented in the new textbook, "Tieng Anh 10 - Global Success", for 10th graders. It employs qualitative methods with the support of quantitative information. The study applies a questionnaire, semi-structured interviews, classroom observations and teaching materials to collect data from seven teachers at Le Huu Trac (LHT) High School. The findings reveal that most teachers appreciate socio-cultural integrations (SCI) and agree that SCI does not prevent progress in terms of language accuracy. SCI's motivational benefits and positive impacts on learners' language skills were approved. However, teachers devote little time and effort to SCI. The study also proposes several implications and suggestions. [ABSTRACT FROM AUTHOR]

Abstract

Defunctioning stomas (ileostomy and colostomy) may be used prior to commencement of neoadjuvant therapy in patients with locally advanced colon or rectal cancer, in order to prevent clinical large bowel obstruction caused by radiotherapy associated oedema or progression of disease in patients who are not obstructed. However, the exact rate of clinical obstruction in patients undergoing neoadjuvant therapy who do not receive a defunctioning stoma is not known. Furthermore, it is not clear which factors predispose patients to developing clinical large bowel obstruction. Given that defunctioning stomas are associated with post operative and intra-operative risks, it is not currently possible to tailor defunctioning stomas to patients who have the greatest risk of developing obstruction. This systematic review which is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement (PRISMA), aims to define the role of defunctioning stomas in prevention of obstruction patients with locally advanced colon or rectal cancer while undergoing neoadjuvant therapy. Two researchers will perform the literature search which will include all published and "in process" articles published in the English language between 2002-2022 in the following databases: EMBASE (OVID), MEDLINE (EBSCO), CINHAL complete, Web of Science, Cochrane Central Registry of Controlled Trials, Clinical Trials Registry. The full text of the selected articles will be independently screened by two researchers against the inclusion criteria. Data will be extracted from each article regarding: study design, participants, type of intervention and outcomes. The effect size will be expressed in incidence rates and when appropriate in relative risk with 95% confidence intervals. If possible, we will perform a meta-analysis. Heterogeneity will be assessed using I2 statistics. We will pool the data extracted from the randomised controlled trials to perform a meta-analysis using the Review Manager 5 software (RevMan 5). The Grades of Recommendation, Assessment, Development and Evaluation (GRADE) system will be used to assess the certainty of the evidence.

Abstract

Introduction The COVID-19 pandemic resulted in a significant disruption of colorectal cancer (CRC) care pathways. This study evaluates the management and outcomes of patients with primary locally advanced or recurrent CRC during the pandemic in a single tertiary referral centre. Methods Patients undergoing elective surgery for advanced or recurrent CRC with curative intent between March 2020 and March 2021 were identified. Following first multidisciplinary team discussion patients were broadly classified into two groups: straight to surgery (n=22, 45%) or neoadjuvant therapy followed by surgery (n=27, 55%). Primary outcome was COVID-19-related complication rate. Results Forty-nine patients with a median age of 66 years (interquartile range: 54–73) were included. No patients developed a COVID-19 infection or related complication during hospital admission. Significant delays were identified in the treatment pathway of patients in the straight to surgery group, mostly due to delays in referral from external centres. Nine of 22 patients in the straight to surgery group had evidence of tumour progression compared with 3 of 27 in the neoadjuvant group (p=0.015839). Seven of 27 patients in the neoadjuvant group showed evidence of tumour regression. During the study, surgical waiting times were reduced, and more operations were performed during the second wave of COVID-19. Conclusion This study suggests that it is possible to mitigate the risks of COVID-19-related complications in patients undergoing complex surgery for locally advanced and recurrent CRC. Delay in surgical intervention is associated with tumour progression, particularly in patients who may not have neoadjuvant therapy. Efforts should be made to prioritise resources for patients requiring time-sensitive surgery for advanced and recurrent CRC.

Abstract

Background: Ovarian cancer cytoreductive surgery necessitates the use of advanced Simulation-Based Learning (SBL) to optimise skill-based teaching and achieve technical proficiency. Objective: We describe and appraise the role of a novel postgraduate cadaveric course for cytoreductive surgery for advanced ovarian/fallopian tube or primary peritoneal cancer. Materials and Methods: Several consultant-level surgeons with expertise in upper gastrointestinal, colorectal, hepatobiliary and urological surgery, were invited to teach their counterpart GO surgeons. The 2-day course curriculum involved advanced dissections on thiel-embalmed cadavers. All dissections included applicable steps required during GO cytoreductive surgeries. Outcome measures: We used a feedback questionnaire and structured interviews to capture trainers and delegates views respectively. Results: All delegates reported a positive educational experience and improvement of knowledge in all course components. There was no difference in the perception of feedback across junior versus senior consultants. Trainers perceived this opportunity as a “2-way learning” whether they got to explore in depth the GO perspective in how and which of their skills are applicable during cytoreductive surgery. Conclusions: Collaborating with other surgical specialities promotes a “learning from the experts” concept and has potential to meet the rapidly increased demand for multi-viscera surgical excellence in GO surgery. What’s new? The concept of involving experts from other surgical disciplines in advanced cadaveric courses for cytoreductive surgery in ovarian cancer, will solidify the effort to achieve excellence in the GO training. Such courses can be essential educational adjunct for most GO fellowships.

Abstract

Aim: At presentation, 15–20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection. Method: Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival. Results: Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006). Conclusion: Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.

Abstract

Lung cancer is responsible for 21% of cancer deaths in the UK and five-year survival rates are heavily influenced by the stage the cancer was identified at. Recent studies have demonstrated the capability of AI methods for accurate and early diagnosis of lung cancer from routine scans. However, this evidence has not translated into clinical practice with one barrier being a lack of interpretable models. This study investigates the application Variational Autoencoders (VAEs), a type of generative AI model, to lung cancer lesions. Proposed models were trained on lesions extracted from 3D CT scans in the LIDC-IDRI public dataset. Latent vector representations of 2D slices produced by the VAEs were explored through clustering to justify their quality and used in an MLP classifier model for lung cancer diagnosis, the best model achieved state-of-the-art metrics of AUC 0.98 and 93.1% accuracy. Cluster analysis shows the VAE latent space separates the dataset of malignant and benign lesions based on meaningful feature components including tumour size, shape, patient and malignancy class. We also include a comparative analysis of the standard Gaussian VAE (GVAE) and the more recent Dirichlet VAE (DirVAE), which replaces the prior with a Dirichlet distribution to encourage a more explainable latent space with disentangled feature representation. Finally, we demonstrate the potential for latent space traversals corresponding to clinically meaningful feature changes., Comment: 10 pages (main paper), 5 pages (references), 5 figures, 2 tables, work accepted for BMVC 2023

The M-OMENTUM study compared omental-derived stromal-vascular cell-fraction (OSVCF) / alginate gel composite vs control subgroups to prevent murine AL. Methods C57BL-6 mice were subjected to an AL model with a leak rate (LR) of 40% and randomised (1:1) to OSVCF / alginate gel or control subgroups (gel alone and no treatment) powered to detect a 20% minimum difference (50% absolute reduction in LR); HO Licence PP9886008. Mice underwent laparotomy and colo-colonic anastomoses. In the intervention group, OSVCF was harvested and applied to the anastomosis in an alginate gel. Mice underwent schedule 1 killing at day 7 or earlier if they failed to meet wellness thresholds. The primary outcome was LR. Secondary outcomes included leak severity, weight, and adhesion score. An intention-to-treat analysis was performed. Results 128 mice (M:64/F:64), mean age 13.1 weeks (SD,1.2), mean weight, 24.1g (SD,4.3) were randomised. OSVCF/Gel containing mean 3.3×103cells/mg (SD,0.3×103) was applied in the intervention group. Overall LR was 49.2%. There was a numerical difference in LRs between the intervention group (30/64, 46.9%) and control groups (33/64, 51.5%) with a LR reduction of 9.1% (RR 0.91 [95%CI:0.64-1.69]; P=0.72). 12/33(36.4%) that received gel alone and 5/33(15.2%) that received no treatment developed an abscess rather than feculent peritonitis (RR 2.26 [95%CI:1.11-5.20]; P=0.04). Conclusion OSVCF/gel produced a 9.1% reduction in LR, but this did not reach statistical significance. The application of gel to an anastomosis alters the severity of anastomotic leak, favouring abscess formation rather than faecal peritonitis.

Abstract

Abstract: Introduction: Reduction in hospital stay, blood loss, postoperative pain and complications are common findings after laparoscopic liver resection, suggesting that the laparoscopic approach may be a suitable alternative to open surgery. Some concerns have been raised regarding cost effectiveness of this procedure and potential implications of its large-scale application. Our aim has been to determine cost effectiveness of laparoscopic liver surgery by a case-matched, case–control, intention-to-treat analysis of its costs and short-term clinical outcomes compared with open surgery. Methods: Laparoscopic liver segmentectomies and bisegmentectomies performed at Ninewells Hospital and Medical School between 2005 and 2007 were considered. Resections involving more than two Couinaud segments, or involving any synchronous procedure, were excluded. An operation-magnitude-matched control group was identified amongst open liver resections performed between 2004 and 2007. Hospital costs were obtained from the Scottish Health Service Costs Book (ISD Scotland) and average national costs were calculated. Cost of theatre time, disposable surgical devices, hospital stay, and high-dependency unit (HDU) and intensive care unit (ICU) usage were the main endpoints for comparison. Secondary endpoints were morbidity and mortality. Statistical analysis was performed with Student’s t-test, χ 2 and Fisher exact test as most appropriate. Results: Twenty-five laparoscopic liver resections were considered, including atypical resection, segmentectomy and bisegmentectomy, and they were compared to 25 matching open resections. The two groups were homogeneous by age, sex, coexistent morbidity, magnitude of resection, prevalence of liver cirrhosis and indications. Operative time (p < 0.03), blood loss (p < 0.0001), Pringle manoeuvre (p < 0.03), hospital stay (p < 0.003) and postoperative complications (p < 0.002) were significantly reduced in the laparoscopic group. Overall hospital cost was significantly lower in the laparoscopic group by an average of £2,571 (p < 0.04). Conclusions: Laparoscopic liver segmentectomy and bisegmentectomy are feasible, safe and cost effective compared to similar open resections. Large-scale application of laparoscopic liver surgery could translate into significant savings to hospitals and health care programmes.

Abstract

The international FOxTROT trial, recently published in the Journal of Clinical Oncology, (ref awaited) is the first randomised controlled trial testing neoadjuvant chemotherapy (NAC) with oxaliplatin and 5-fluorouracil in locally advanced but operable colon cancer. 1053 patients with operable, radiologically staged T3-T4, N1-2, M0 colon cancer were recruited from over 100 sites in the UK, Sweden and Denmark. Patients were randomised to 6 weeks of planned chemotherapy before resectional surgery, followed by adjuvant chemotherapy; or upfront surgery followed by adjuvant chemotherapy (total 18 weeks in both arms). NAC was safe and, compared with standard treatment, there was no increase in surgical complications, a higher R0 rate (95% vs 89%, p0.001), and significant primary and nodal pathological downstaging. The trial met its primary endpoint with fewer patients experiencing recurrent or residual disease at 2 years with NAC compared with control: (16.8% vs 21.2%, risk ratio=0.74, p=0.042). Rapid translation of these results into patient benefit is expected, particularly as the chemotherapeutic agents are already used routinely and do not incur any additional cost or toxicity. However, offering NAC as standard care for advanced colon cancer requires adaptations to current treatment pathways so presents organisational challenges. To date, the Leeds Cancer Centre, St James's University Hospital, UK has commenced 64 patients on the novel pathway following presentation and adoption of the FOxTROT results. Here, we describe our experience and share strategies developed across the MDT to minimise impact on person hours, service capacity and budget, whilst building patient safety and confidence.

Abstract

Pelvic exenteration is a complex operation performed for locally advanced and recurrent pelvic cancers. The goal of surgery is to achieve clear margins, therefore identifying adjacent or involved organs, bone, muscle, nerves and/or vascular structures that may need resection. While these extensive resections are potentially curative, they can be associated with substantial morbidity. Recently, there has been a move to centralize care to specialized units, as this facilitates better multidisciplinary care input. Advancements in pelvic oncology and surgical innovation have redefined the boundaries of pelvic exenterative surgery. Combined with improved neoadjuvant therapies, advances in diagnostics, and better reconstructive techniques have provided quicker recovery and better quality of life outcomes, with improved survival This article provides highlights of the current management of advanced pelvic cancers in terms of surgical strategy and potential future developments.

Abstract

Aim Anastomotic leak is the most feared complication of gastrointestinal surgery. Mesenchymal stem cell technology is used clinically to promote wound healing; however, the safety and efficacy of this technology on anastomotic healing has yet to be defined. The aim of this study was to investigate whether mesenchymal stem cells confer any benefit when applied to animal models for gastrointestinal anastomotic leak, identify the methodology and how efficacy is assessed. Methods The MEDLINE, EMBASE, WebofScience and Cochrane Library databases were interrogated between 1 January1947 to 1 May 2020. All studies where mesenchymal stem cells were applied to laboratory animal leak models to demonstrate a healing effect were considered. All experimental and histological outcomes were examined. Compliance to ARRIVE and current International Consensus was assessed. Results A total of 1205 studies were screened. Twelve studies reported on 438 gastrointestinal anastomoses in four species using 11 models; seven in the colon. No studies utilised a model with a known leak rate. Significant variance was observed in histological outcomes with efficacy demonstrated in five out of 12 studies. One study demonstrated a benefit in leak rate. Colorectal studies had a greater median ARRIVE compliance, 60.8% (IQR 63.2-64.5) compared to noncolorectal 45.4% (IQR 43.8-49.0). Conclusions Mesenchymal stem cell delivery to an animal anastomosis is safe and feasible. Use may confer benefit but findings are currently limited to surrogate histological outcomes. There is consistency in outcome measures reported but variance in how this is assessed. Poor compliance to ARRIVE but good compliance to current international consensus in leak models of the colon was observed.

Abstract

Background and Aim Equipment consumption is the third largest contributor to the carbon footprint of surgery. Laparoscopic surgery is particularly resource intensive. The aim of this quality improvement project is to reduce the carbon footprint of laparoscopic appendicectomies performed at this high volume trust. Methods The laparoscopic appendicectomy was process-mapped and carbon footprint calculations performed. Three areas of change were identified: elimination of single use gowns and drapes, elimination of peri-operative catheterisation, and rationalisation of the equipment tray from 119 to 49 items. A staff survey was used to identify practices and gain feedback on the proposed changes. Changes were implemented from January 2022. Surgeons are able to ask for a ‘sustainable appendicectomy pathway’ at team brief. Procedures were monitored for one week. Results Survey feedback indicated 100% (n=19) supported the proposed changes. The interventions save an estimated 7.48kgCO2e and £25.1 per procedure. No extra equipment was required during the procedures monitored. Conclusions The interventions are predicted to save annually 3.9TCO2e and £13,081 in the approximately 500 appendicectomies performed in this trust, and can be extrapolated to many types of procedures. Support from all members of the operating department is vital to sustaining the momentum of interventions. Following initial positive results, changes were extended to only use reusable gowns in one of the CEPOD theatres which perform around 2400 procedures/year. This will lead to a saving of at least 6386 disposable gowns/year (1.43T of waste). Further plans within this trust are to make the ‘sustainable appendicectomy pathway’ an opt-out decision.
