1. Autotuning of Isotropic Hardening Constitutive Models on Real Steel Buckling Data with Finite Element Based Multistart Global Optimisation on Parallel Computers

Author: Anton Shterenlikht, Mohammad M. Kashani, Nicholas A. Alexander, Gethin Williams, and Adam J. Crewe
Subjects: Electronic computers. Computer science, QA75.5-76.95
Abstract: An automatic framework for tuning plastic constitutive models is proposed. It is based on multistart global optimisation method, where the objective function is provided by the results of multiple elastoplastic finite element analyses, executed concurrently. Wrapper scripts were developed for fully automatic preprocessing, including model and mesh generation, analysis, and postprocessing. The framework is applied to an isotropic power hardening plasticity using real load/displacement data from multiple steel buckling tests. M. J. D. Powell’s BOBYQA constrained optimisation package was used for local optimisation. It is shown that using the real data presents multiple problems to the optimisation process because (1) the objective function can be discontinuous, yet (2) relatively flat around multiple local minima, with (3) similar values of the objective function for different local minima. As a consequence the estimate of the global minimum is sensitive to the amount of experimental data and experimental noise. The framework includes the verification step, where the estimate of the global minimum is verified on a different geometry and loading. A tensile test was used for verification in this work. The speed of the method critically depends on the ability to effectively parallelise the finite element solver. Three levels of parallelisation were exploited in this work. The ultimate limitation was the availability of the finite element commercial solver license tokens.

3. TH3.10 An audit assessing factors contributing to the 5-year disease recurrence rate after curative resection of rectal cancer

Author: Nadia Youssef, Ishani Sinha, and Gethin Williams
Subjects: Surgery
Abstract: Aim To study the 5-year recurrence rate of rectal adenocarcinomas following curative surgery in a cohort of patients from a single Health Board, and to identify statistically significant risk factors of disease recurrence. Method This audit included a total of 95 patients who underwent elective resections of primary rectal cancer between January 2014 and January 2016 at a single health board. The 5-year disease recurrence rate was documented. Medical records were accessed via the Clinical Workstation system and a number of factors were recorded and statistically analysed on Microsoft Excel using z-score for two populations portions. A p-value of Results Of the 92 patients included in this audit, 23 suffered disease recurrence. Younger age at diagnosis, tumour perforation, positive lymph nodes, tumour involvement of circumferential resection margin, and extramural vascular invasion were all associated with significantly increased risk of disease recurrence and poorer prognosis. Postoperative complications were observed in 26% of the cohort and it was significantly (p=0.009) associated with disease recurrence. Although more patients who developed disease recurrence received chemoradiation as part of their initial disease management, the number was not statistically significant. Conclusion The audit supports lowering the age of bowel cancer screening. Strategies are required to minimise the risk of postoperative complications in patients undergoing elective rectal cancer resections. Reasons must be identified as to why patients with a higher risk of recurrence, undergoing curative surgical resection of tumours, do not have higher uptake of adjuvant and neoadjuvant chemoradiation.

4. TU4.9 Major elective colorectal surgery at a non-acute site: is it safe or not?

Author: Zaid Hammoudeh, Gethin Williams, and Rhodri Codd
Subjects: Surgery
Abstract: Introduction Recent reorganisation resulted in elective surgical services being separated from emergency facilities due to a new hospital site in our Health Board. Clinicians were initially concerned with regards to postoperative complications and the potential need for transfer to the acute site (6 miles away) for ongoing emergency management. There are no ICU or emergency theatre facilities at the cold site. We audited the first year of the service reconfiguration. Methods This study looked at unexpected transfer of major colorectal surgical patients occurring between December 2020 to 2021 from the elective hospital to the acute site. The prospectively maintained departmental database was interrogated. Results There were 263 patients undergoing colorectal operations over 12 months. 31 patients (12%) required step-up to the acute hospital for further post-operative care. 10 returned to theatre (4 anastomotic leaks, 1 anastomotic bleed, 1 fluid collection washout, 3 SBO, 1 stoma revision). The remaining 21 patients were managed conservatively by the surgical team (8) or taken over by the medical team (13). The main surgical reason for step-up was due to anastomotic leakage (7). Other step-up reasons included cardiorespiratory compromise (9), infection (6), bowel obstruction (3) and bleeding (2). Median time for transfer was day 4 (range 0–11 days) postoperatively. No transfer delay causing harm was reported. The 30-day mortality rate for all 263 patients was 0%. Conclusion Transfer to the acute site seems to have been safe, timely and effective in its first year. Patients have received appropriate and emergency care for these unpredictable complications.

Abstract: Aim The Covid‐19 pandemic has delayed elective colorectal cancer (CRC) surgery. The aim of this study was to see whether or not this may affect overall survival (OS) and disease‐free survival (DFS). Method A systematic review was carried out according to PRISMA guidelines (PROSPERO ID: CRD42020189158). Medline, EMBASE and Scopus were interrogated. Patients aged over 18 years with a diagnosis of colon or rectal cancer who received elective surgery as their primary treatment were included. Delay to elective surgery was defined as the period between CRC diagnosis and the day of surgery. Meta‐analysis of the outcomes OS and DFS were conducted. Forest plots, funnel plots and tests of heterogeneity were produced. An estimated number needed to harm (NNH) was calculated for statistically significant pooled hazard ratios (HRs). Results Of 3753 articles identified, seven met the inclusion criteria. Encompassing 314 560 patients, three of the seven studies showed that a delay to elective resection is associated with poorer OS or DFS. OS was assessed at a 1 month delay, the HR for six datasets was 1.13 (95% CI 1.02–1.26, p = 0.020) and at 3 months the pooled HR for three datasets was 1.57 (95% CI 1.16–2.12, p = 0.004). The estimated NNH for a delay at 1 month and 3 months was 35 and 10 respectively. Delay was nonsignificantly negatively associated with DFS on meta‐analysis. Conclusion This review recommends that elective surgery for CRC patients is not postponed longer than 4 weeks, as available evidence suggests extended delays from diagnosis are associated with poorer outcomes. Focused research is essential so patient groups can be prioritized based on risk factors in future delays or pandemics.

Abstract: Aim The involvement of pelvic sidewall (PSW) lymph nodes in rectal cancer is a marker of locally advanced disease and poor prognosis. Eastern countries generally advocate lateral lymph node dissection (LLND) over the Western approach of neoadjuvant chemoradiotherapy and more limited surgery. The aim of this study was to evaluate how these advanced cancers were treated in three UK Health Boards. Methodology This was a retrospective review of three colorectal multidisciplinary team meetings from 2008 to 2016. All patients with rectal cancer and suspicious PSW lymph nodes on pretreatment MRI were included. Results There were 153 (6.2%) patients who met the inclusion criteria from a total of 2461 diagnosed rectal cancers. There was significant variability between the three centres with surgical intervention ranging from 59.2% to 84.4%, P = 0.015. There were 81 patients who had neoadjuvant chemoradiotherapy prior to surgery; of these 67 (82.7%) still had positive PSW nodes on the restaging MRI, but only 13 (19.4%) had LLND. There was no difference in local recurrence (15.3% vs 11.8%, P = 0.66), 5-year overall survival (69.2% vs 80.1%, P = 0.16) or 5-year disease-free survival (69.2% vs 79.4%, P = 0.72) between patients having LLND and those receiving standard neoadjuvant treatment followed by total mesorectal excision surgery. Conclusions This study has demonstrated that rectal cancer patients with PSW positive nodal disease have advanced disease, mostly of the lower rectum, and receive a highly heterogeneous spectrum of therapies, even within a relatively small geographical area. Greater accuracy in our preoperative staging is needed to select those patients who will benefit from LLND surgery.

Abstract: AIM Delayed closure of ileostomy following an anterior resection for rectal cancer in the UK is common. The aims of this study were (i) to investigate the variation in patient pathways between hospitals, (ii) to identify the key learning points from units with the shortest time to closure and (iii) to develop guidance for a pathway to minimize delay in ileostomy closure. METHOD This was a mixed methods study. Thirty-eight colorectal units in the UK completed a short online survey. Nine colorectal units in Wales filled in an additional, expanded version of the survey. Semi-structured interviews were performed with clinicians from the six best performing units in terms of timely ileostomy closure. The optimal pathway suggested is based on the best evidence available and the Association of Coloproctology of Great Britain and Ireland guidelines. RESULTS Qualitative analysis revealed that 5% of units (n = 2) have a local target time for ileostomy closure. Of all units, 90% (n = 34) would consider implementing a pathway if guidelines were developed. In-depth interviews highlighted the importance of a multidisciplinary approach, a dedicated coordinator to facilitate timely booking, and consensus on whether closure should be performed before or after adjuvant chemotherapy. CONCLUSION There is a lack of national guidance in timing of contrast studies and ileostomy closure. Key aspects to consider are better information at consent regarding stoma closure timing, a dedicated person to track patients and the planning of contrast studies at discharge from initial surgery. With a dedicated approach closure of ileostomy within 10-12 weeks is feasible for most units.

Abstract: 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.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.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.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.Los adultos mayores sometidos a cirugía abdominal de urgencia tienen resultados significativamente peores que los adultos jóvenes. Para aquellos pacientes que sobreviven, el nivel de atención que requieren tras el alta hospitalaria se desconoce y esta información podría servir de guía en la toma de decisiones. El estudio ELF (Emergency Laparotomy and Frailty) tenía como objetivo determinar si la fragilidad preoperatoria en adultos mayores se asociaba con un aumento de la dependencia en el momento del alta. MÉTODOS: El estudio ELF era un estudio multicéntrico extenso efectuado en el Reino Unido (n = 49) que incluyó una cohorte prospectiva de 934 pacientes mayores ( 65 años) sometidos a laparotomía de urgencia durante marzo-junio de 2017. El objetivo fue establecer si la fragilidad preoperatoria aumentaba el nivel de asistencia en el momento del alta en comparación con el nivel de asistencia preoperatorio. Para el análisis se utilizó una regresión logística multinivel ajustada a características previas al ingreso: fragilidad, edad del paciente, género, y nivel de asistencia.La edad media de los pacientes fue 76,2 años (DE = 6,83), con un 57% de mujeres, un 20,2% de pacientes frágiles y un 37,4% de adultos mayores que presentaron un aumento en el nivel de asistencia en el momento del alta. Un aumento de la fragilidad se asoció con un incremento en el nivel de asistencia en el momento del alta (y mayor poder predictivo que la edad). La razón de oportunidades (odds ratio, OR) ajustada por el aumento del nivel de asistencia fue 4,48 (i.c. del 95% 2,03-9,91) para pacientes aparentemente vulnerables (Clinical Frailty Scale, CFS 4); 5,94 (i.c. del 95% 2,54-13,90) para aquellos ligeramente frágiles (CFS 5); y 7,88 (i.c. del 95% 2,97-20,79) para aquellos con fragilidad moderada o grave (CFS 6 and 7) en comparación con pacientes en buenas condiciones. CONCLUSIÓN: Este es el primer estudio que documenta que más del 37% de adultos mayores sometidos a laparotomía de urgencia precisaron un aumento en el nivel de asistencia en el momento del alta. La evaluación de la fragilidad debería integrarse en todas las unidades quirúrgicas de agudos para ayudar a compartir la toma de decisiones y los planes de tratamiento.

Abstract: Background The emergence of the Coronavirus pandemic has placed increased demands on the NHS workforce, especially in medical and intensive care units. The subsequent redistribution of surgical house officers to accommodate this in a single centre has possibly negatively impacted on the effective discharge notification of acute surgical patients. Methods: Discharge summaries of all patients discharged from a Surgical Assessment Unit were collected and analysed, to identify the date of completion and grade of responsible clinician. Data collection was carried out over three weeks before the initiation of lockdown measures and continued for a further three weeks during the peak of the Coronavirus pandemic with a three-week interventional period in between. Results In the initial audit, 36.2% of the 246 patients had delayed discharge summaries with an average of 7 days to complete. On re-evaluation, 45.3% of the 223 patients had delayed discharge summaries, with an average of 12 days to complete. A survey conducted post-re-audit identified that the most common reason for this was due to time constraints. Conclusions The reallocation of surgical staff has affected communication between primary and secondary care. Given the potential repercussions of these delays, healthcare systems should be made aware of this consequence, especially in preparation for any future resurgences.

Abstract: Surgical site infections (SSIs) have a significant impact on a patient's post-operative morbidity and mortality. Colorectal operations have an increased SSI rate exemplified by the operations being clean-contaminated or contaminated procedures.Recently published in this journal, Falconer and colleagues report a large longitudinal cohort prospective study of 1075 Scottish patients with analysis of 4 different SSI bundles, aimed to identify their impact on SSI rates [1]. The primary outcomes were overall and superficial SSI rates during the inpatient stay. The authors are to be congratulated on implementing a robust quality improvement methodological approach to reduce their SSI rate from 16.4% to 5.1%. The independent assessment of post-operative wounds by the infection control team should be commended, as this facilitates unbiased and accurate data collection prior to patient's hospital discharge.

18. A new Chapter for the Association of Coloproctology of Great Britain and Ireland

Author: Gethin Williams and R. F. Kokelaar
Subjects: 2019-20 coronavirus outbreak, Coronavirus disease 2019 (COVID-19), business.industry, Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), Association (object-oriented programming), Gastroenterology, Audit, Patient care, United Kingdom, Colonic Diseases, Rectal Diseases, Nursing, Pandemic, Medicine, Humans, Quality of care, business
Abstract: The Coronavirus pandemic has significantly impacted on the practice of colorectal surgery and other branches of medicine. In addition to disrupting patient care at every level, it has also decimated the normal business and structures that maintain the high quality of care that our patients expect. These vary from local departmental audits to the function of learned societies such as the Association of Coloproctology of Great Britain and Ireland. During this challenging and rapidly evolving era, clinicians crave communication and being connected to their peers.

19. Safe, sustained reduction in meropenem and piperacillin/tazobactam use in a medical high dependency unit

Abstract: There is widespread overuse of ultra-broad spectrum antibiotics (UBSA) such as meropenem and piperacillin/tazobactam (PTZ). Reductions in their use are needed to preserve their effectiveness. Using electronic prescribing data we recorded administrations of meropenem and PTZ per month in a 12-bed medical high dependency unit (HDU) from April 2016 to March 2019. During this time there were three interventions (an antimicrobial stewardship round began in March 2017, PTZ was removed from empirical prescribing guidelines in May 2017, and a restricted antimicrobial audit began in June 2017). The latter two interventions were prompted by a national PTZ shortage. In 2016/17 meropenem and PTZ use was 56 and 113 daily defined doses/100 acute occupied bed days (AOBD) respectively, falling to 32 and 60 in 2017/18, and to 25 and 38 in 2018/19. This represented a 55% reduction in meropenem use and a 77% reduction in PTZ use over 2 years. The drop in use was due to both fewer patients being started on UBSA and shorter durations of treatment. The use of 4C antibiotics (clindamycin, cephalosporins, co-amoxiclav and ciprofloxacin/levofloxacin) did not increase. There was no increase in unit mortality, or change in the prevalence of ESBL-producing organisms. We describe a multi-modal intervention that, coupled with strong clinical engagement, resulted in a safe, sustained reduction in both meropenem and PTZ use in a medical HDU, without using more 4C antibiotics. We hypothesize that “top down” policies helped reduce UBSA initiation, whereas a “bottom-up” ward-based initiative helped review and stop unnecessary use.

Abstract: INTRODUCTION: Colon ischaemia (CI) is a significant complication of open (OR) and endovascular (EVAR) repair of abdominal aortic aneurysm (AAA). With a rapid increase in EVAR uptake, contemporary data demonstrating the differing rates and outcomes of CI between EVAR and OR, particularly in the elective setting, are lacking. The aim was to characterise the risk and consequences of CI in elective AAA repair comparing EVAR with OR.METHODS: A systematic review and meta-analysis of the literature was performed using the Cochrane collaboration protocol and reported according to the PRISMA guidelines. PubMed, MedLine, and EMBASE were searched for studies reporting CI rates after elective AAA repair. Ruptured AAAs were excluded from analysis.RESULTS: Thirteen studies reporting specific outcomes of CI after elective AAA repair, containing 162,750 evaluable patients (78,151 EVAR and 84,599 OR) were included. All studies found a higher risk of CI with OR than with EVAR. Three studies performed confounder adjustment with CI rates of 0.5-1% versus 2.1-3.6% (EVAR vs. OR) and combined odds ratio of 2.7 (2.0-3.5) for the development of CI with OR versus EVAR. The majority of cases of CI occurred within 30 days and were associated with variable mortality (0-73%) and re-intervention rates (27-54%). GRADE assessment of evidence strength was very low for all outcomes. There was a high degree of heterogeneity between studies both methodologically and in terms of CI rates, re-intervention, mortality, and time to development of CI.CONCLUSIONS: EVAR is associated with a reduced incidence of CI compared with OR.

Abstract: Given the lack of a recent meta-analysis on this topic, we attempted to quantify the delay from diagnosis to surgical treatment in elective colorectal cancer from the available literature. The evidence base available to the authors was of poor quality as acknowledged by the ROBINS-I score which declared three papers at serious risk of bias.

Abstract: Increasing climate commitments to meet the Paris Agreement goal avoids large numbers of heat-related deaths in U.S. cities., Current greenhouse gas mitigation ambition is consistent with ~3°C global mean warming above preindustrial levels. There is a clear need to strengthen mitigation ambition to stabilize the climate at the Paris Agreement goal of warming of less than 2°C. We specify the differences in city-level heat-related mortality between the 3°C trajectory and warming of 2° and 1.5°C. Focusing on 15 U.S. cities where reliable climate and health data are available, we show that ratcheting up mitigation ambition to achieve the 2°C threshold could avoid between 70 and 1980 annual heat-related deaths per city during extreme events (30-year return period). Achieving the 1.5°C threshold could avoid between 110 and 2720 annual heat-related deaths. Population changes and adaptation investments would alter these numbers. Our results provide compelling evidence for the heat-related health benefits of limiting global warming to 1.5°C in the United States.

Abstract: Background: End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods: This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model. Results: In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6.9 per cent) from low-HDI, 254 (15.5 per cent) from middle-HDI and 1268 (77.6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57.5, 40.9 and 35.4 per cent; P, Medical Research Council, MR/N022114/1; National Institute for Health Research, 16/136/79

Abstract: We read with great interest Moncur and colleagues'1 recent systematic review investigating the impact and outcomes of postoperative anaemia in colorectal cancer patients. We congratulate the authors on an interesting review of the current literature that clearly establishes a clinical and academic need to ascertain the true effect of postoperative anaemia, given its high prevalence and potential negative effects on patient outcomes. However, we feel that the novel bias tool, utilised to add improved academic rigor to reviews of this kind, was performed incorrectly in this case.

Abstract: INTRODUCTION: Several articles have been published about the reorganisation of surgical activity during the COVID-19 pandemic but few, if any, have focused on the impact that this has had on emergency and trauma surgery. Our aim was to review the most current data on COVID-19 to provide essential suggestions on how to manage the acute abdomen during the pandemic. METHODS: A systematic review was conducted of the most relevant English language articles on COVID-19 and surgery published between 15 December 2019 and 30 March 2020. FINDINGS: Access to the operating theatre is almost exclusively restricted to emergencies and oncological procedures. The use of laparoscopy in COVID-19 positive patients should be cautiously considered. The main risk lies in the presence of the virus in the pneumoperitoneum: the aerosol released in the operating theatre could contaminate both staff and the environment. CONCLUSIONS: During the COVID-19 pandemic, all efforts should be deployed in order to evaluate the feasibility of postponing surgery until the patient is no longer considered potentially infectious or at risk of perioperative complications. If surgery is deemed necessary, the emergency surgeon must minimise the risk of exposure to the virus by involving a minimal number of healthcare staff and shortening the occupation of the operating theatre. In case of a lack of security measures to enable safe laparoscopy, open surgery should be considered.

Abstract: Summary Background Emergency abdominal surgery is associated with poor patient outcomes. We studied the effectiveness of a national quality improvement (QI) programme to implement a care pathway to improve survival for these patients. Methods We did a stepped-wedge cluster-randomised trial of patients aged 40 years or older undergoing emergency open major abdominal surgery. Eligible UK National Health Service (NHS) hospitals (those that had an emergency general surgical service, a substantial volume of emergency abdominal surgery cases, and contributed data to the National Emergency Laparotomy Audit) were organised into 15 geographical clusters and commenced the QI programme in a random order, based on a computer-generated random sequence, over an 85-week period with one geographical cluster commencing the intervention every 5 weeks from the second to the 16th time period. Patients were masked to the study group, but it was not possible to mask hospital staff or investigators. The primary outcome measure was mortality within 90 days of surgery. Analyses were done on an intention-to-treat basis. This study is registered with the ISRCTN registry, number ISRCTN80682973. Findings Treatment took place between March 3, 2014, and Oct 19, 2015. 22 754 patients were assessed for elegibility. Of 15 873 eligible patients from 93 NHS hospitals, primary outcome data were analysed for 8482 patients in the usual care group and 7374 in the QI group. Eight patients in the usual care group and nine patients in the QI group were not included in the analysis because of missing primary outcome data. The primary outcome of 90-day mortality occurred in 1210 (16%) patients in the QI group compared with 1393 (16%) patients in the usual care group (HR 1·11, 0·96–1·28). Interpretation No survival benefit was observed from this QI programme to implement a care pathway for patients undergoing emergency abdominal surgery. Future QI programmes should ensure that teams have both the time and resources needed to improve patient care.

Abstract: Aim There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology. Methods Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines. Results All aspects of surgical care for IBD have been included along with 157 recommendations for management. Conclusion These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

Abstract: Aims The incidence of clostridium difficile infection (CDI) has been reported as high as 4% following ileostomy reversal and can be associated with significant morbidity. A systematic review on this subject has not been previously reported; our aims were to review the literature to establish incidence and to evaluate factors that may contribute to an increase risk of CDI following ileostomy reversal. Methods A systematic review of Ovid, Embase and Medline was undertaken. Search terms included clostridium difficile, reversal of ileostomy and ileostomy closure. Articles were included where at least one case of clostridium difficile associated diarrhoea following reversal of defunctioning ileostomy was reported. Data extraction for articles was performed by two authors, using predefined data fields. Primary outcome measure was incidence of CDI amongst patients undergoing ileostomy reversal. Secondary outcomes were defunctioning time, antibiotic regime, acid suppression, time to onset of symptoms and study conclusions including colectomy and mortality rate. Results Eleven articles were included (Case reports (5) or cohort studies (6)). The overall incidence of CDI was 1.8% (242/13728). Mean defunctioning time was 8.7 months (range 6-12). A variety of antibiotic regimes were described. Mean time to onset of symptoms was 6 days (range 3-14). Acid suppression use, colectomy or mortality rate was frequently not reported. Conclusion CDI should be recognised as a potentially life-threatening complication of ileostomy closure. Careful consideration should be given to peri-operative antibiotic regime, acid suppression, timing of reversal and appropriate pre-operative counselling of patients.

Abstract: Population screening for colorectal cancer (CRC) was introduced to Wales in October 2008. The aim of this study was to evaluate the early impact of screening on CRC services.Prospectively collected data from the Bowel Screening Wales (BSW) programme and the Welsh Bowel Cancer Audit (WBCA) were used to identify all screen-detected (SD) CRC diagnoses in Wales between April 2009 and March 2011. Data from the WBCA were used to calculate surgical outcomes.444 SD cancers were registered during the study period representing 11% of all CRC diagnoses. There was a 9.9% increase in CRC incidence following the introduction of the BSW. SD patients presented with earlier stage disease; SD Dukes' A 35.1% vs 13.9% symptomatic patients (p0.001) and SD Dukes' D 7.4% vs 21.8% symptomatic, (p0.001). There were more colonic cancers among the SD population (p0.001). The resection rate for SD cancers was 89%, significantly higher than symptomatic cancers (67.7%; p0.0001). There was variability in the use of polypectomy as a definitive procedure to treat CRC between units. Overall laparoscopic resection was used in 52% of cases but with considerable interunit variability (0-92%).The introduction of screening has increased the workload of the colorectal multidisciplinary teams in Wales. This has occurred through both an increase in case volume and the identification of more patients with early stage disease. There is considerable interunit variability in the use of techniques of local excision and rates of laparoscopic resection that need to be addressed.

Abstract: Aim Lymph node (LN) metastases are present in up to 17% of early colorectal cancers (pT1). Identification of associated histopathological factors would enable counselling of patients regarding this risk. Method Pubmed and Embase were employed utilizing the terms ‘early colorectal cancer’, ‘lymph node metastasis’, ‘submucosal invasion’, ‘lymphovascular invasion’, ‘tumour budding’ and ‘histological differentiation’. Analysis was performed using REVIEW MANAGER 5.1. Results Twenty-three cohort studies including 4510 patients were analysed. There was a significantly higher risk of LN metastasis with a depth of submucosal invasion > 1 mm than with lesser degrees of penetration (OR 3.87, 95% CI 1.50–10.00, P = 0.005). Lymphovascular invasion was significantly associated with LN metastasis (OR 4.81, 95% CI 3.14–7.37, P 1 mm, lymphovascular invasion, poor differentiation and tumour budding are significantly associated with LN metastasis.

Abstract: OBJECTIVE To determine if diffuse hepatic uptake (DHU) of radioactive iodine (I-131) following radioactive iodine treatment has prognostic implications in otherwise scan-negative patients. METHODS This is a retrospective review of patients treated for differentiated thyroid cancer (DTC) at Beth Israel Deaconess Medical Center between January 1990 and June 2006. This group included patients receiving therapy to ablate presumed remnant tissue, as well as treatment for persistent disease as measured by thyroglobulin or imaging. All patients included in the study had no remnant uptake and otherwise negative posttherapy scans. A total of 57 patients with 63 scans met these criteria. The scans were then scored for DHU on a scale of 0 to 5, with 0 being no uptake and 5 being intense uptake relative to background. RESULTS Sixteen of 63 treatments were remnant ablations. Ten of 57 patients had positive thyroglobulin antibodies. Average DHU was similar in the ablation and therapeutic groups (1.9 vs. 2.3, P = .3). There was no correlation with either I-131 dose or the presence of thyroglobulin antibodies. There was a difference for DHU in the rate of disease-free survival, (undetectable thyroglobulin and no clinical or radiographic evidence of metastasis); 50% of patients with hepatic uptake scores of 0-2 were disease-free compared to 15% with scores of 3-5 (P

Abstract: Aim The risk of peripheral nerve injury associated with laparoscopic colorectal surgery has not been well established. We aimed to identify the number and type of peripheral nerve injuries associated with patient positioning in laparoscopic surgery. Method A systematic review of MEDLINE and Embase was undertaken of English and non-English language articles. Search terms included the key words: laparoscopic, colorectal, nerve injury, nerve damage, brachial plexus, peripheral neuropathy, peripheral nerve injury, nerve and colonic injury. Articles were included where at least one peripheral nerve injury had been documented related to patient positioning at laparoscopic colorectal surgery. Data extraction for articles was conducted by two authors, using predefined data fields. Results Ten cases have been reported in the literature. All injuries involved the brachial plexus. They were associated with a lengthy procedure and abduction of the arm. Conclusion Although rare, the surgeon and theatre team must be aware of the risk of peripheral nerve injury when positioning patients for laparoscopic colorectal procedures.

Abstract: Introduction Malrotation of the midgut and appendiceal mucocoele are both extremely rare pathological conditions in adults. To our knowledge, there are only two reported cases in the English literature with a combination of both conditions. Case History A 65-year-old man presented with a 10-day history of upper abdominal pain associated with abdominal bloating and weight loss. He was otherwise fit and healthy with no significant past medical history. On examination, his abdomen was soft with tenderness and palpable fullness over the left upper quadrant. The initial blood test, chest x-ray and abdominal x-ray demonstrated no significant abnormality. Computed tomography showed a 17cm x 8cm x 6cm elongated cystic mass with possible malrotation of the intestines. Histopathology showed a low grade mucinous tumour of the appendix. At 12 months following surgery, there was no evidence of recurrence or postoperative complications and the patient was discharged from the care of the colorectal team. Conclusions We report a patient with a combination of two rare conditions. This case illustrates how a combination of pathologies can present a challenge to the unwary general surgeon.

Abstract: Aim Parastomal hernias are difficult to manage and recent attention has focused on their prevention including the use of prophylactic mesh at the time of initial surgery. Method A novel ‘anatomical’ approach to stoma formation, the lateral rectus abdominis positioned stoma (LRAPS), involving minimal anterior abdominal wall disruption is described. Results LRAPS was carried out electively (n = 25) or as an emergency (n = 4) for benign or malignant pathology. Twenty-two had a midline laparotomy and all types of stomas were fashioned. There were two early and three later deaths from advanced malignancy. No parastomal hernias have been detected at a mean follow-up of 13 (range 7–18) months and none detected by CT scanning in 20 of 24 patients with colorectal cancer at a mean follow-up of 14 (range 10–18) months. Conclusion LRAPS reduces the incidence of early stomal herniation.

Abstract: Myocardial 18F-FDG uptake in PET scans in patients prepared by the usual fasting protocol may result in difficulties in interpretation because variable uptake may yield false-positive results regarding mediastinal abnormalities. We aimed to analyze, retrospectively, the effect of diet on myocardial FDG uptake.The "fasting" group comprised 101 consecutive patients before a clinical change in the patient preparation protocol. The "new diet" group comprised 60 consecutive patients after the clinical protocol change who were directed to consume a very high-fat, low-carbohydrate, protein-permitted (VHFLCPP) diet before FDG injection. All patients were given a questionnaire that was used to verify diet adherence. Nonadherers or patients failing to complete questionnaires were excluded from analysis. Myocardial uptake was evaluated by measuring the maximum standardized uptake value (SUVmax) in areas defined by CT as being cardiac.The average SUVmax for the fasting group (n = 101) was 8.8 +/- 5.7, and the average SUVmax for the VHFLCPP group (n = 60) was 3.9 +/- 3.6. The one-tailed Student's t test yielded a p value of0.00001.A VHFLCPP meal eaten 3-6 hours before FDG injection suppresses myocardial FDG uptake. This should facilitate definition of mediastinal abnormalities on FDG PET, particularly with stand-alone PET. Furthermore, this patient preparation protocol may permit the detection of biologically active coronary artery disease.

Abstract: Certain stress-induced ancillary findings on myocardial perfusion scintigraphy increase the likelihood that the patient has coronary artery disease (CAD); furthermore, among CAD patients, they indicate more severe and extensive disease, placing these patients at higher risk for future cardiac events. Indeed, in studies with no obvious perfusion defect yet with serious CAD--for example, balanced ischemia--it can be these high-risk findings that necessitate invasive intervention.Besides reversible perfusion defects, such findings include increased pulmonary radiotracer uptake, transient cavity dilatation, increased end-diastolic or end-systolic volume, decreased post-stress ejection fraction, and increased right ventricular tracer uptake on stress images. The pathophysiology underlying these findings is clearly different as they do not always occur together, and each independently predicts more severe and extensive CAD. In the current review, these findings are defined and their significance in diagnosing patients with suspected or known CAD is discussed.

Abstract: Objective Individuals with a strong family history have a high risk of developing colorectal cancer. They could well benefit from targeted screening and their increased risk warrants an invasive procedure such as colonoscopy. This study aims to assess the anxieties of symptom-free relatives offered screening by colonoscopy. Method A simple questionnaire was sent to 50 consecutive people who had colorectal cancer screening by colonoscopy because of a strong family history. Results Forty-five questionnaires were answered. On assessing their anxiety levels before and after colonoscopy, 56% noticed an improvement after the test, 33% were still as anxious and 11% had raised anxiety levels despite screening. Although most of the screening colonoscopies were normal, 44% of asymptomatic relatives undergoing invasive screening had no improvement of their cancer anxieties. Conclusion Screening people with a strong family history of colorectal cancer may be an efficient, cost-effective and focussed way of detecting early neoplasms rather than screening the general population. Using colonoscopy alone however, a large proportion of people still have cancer anxieties after being screened. This small study suggests that in order to attempt to alleviate anxieties, a colonoscopy alone is insufficient for some in this high-risk group.

Abstract: Aim Colovesical fistula (CVF) is an uncommon condition. Diagnosis and management varies according to presentation and aetiology. The identification of patients suitable for conservative management and their outcome following this approach has not been well documented. Methods The clinical outcomes of all patients diagnosed with a CVF over a 7-year period from an uro-radiological database were reviewed. Cases secondary to diverticular disease were analysed with respect to the approach by which they were managed: those treated surgically and those managed conservatively. Results Sixty-two patients (32 men) were diagnosed with CVF of whom 53 (85%) had diverticular disease. Twenty-seven (mean age 69 years, range 42–90) underwent surgery (with a stoma in 59%) with a 30-day mortality of 15%. Those managed conservatively (n = 26) were older (mean age 76 years, range 39–87) and frailer (62% American Society of Anesthesiologists Grades III and IV). At 1 and 3 years following diagnosis there was no difference in mortality between these two groups and only one death was as a consequence of urosepsis. Conclusion Many patients with CVF secondary to diverticular disease can be safely managed non-operatively.

Abstract: To retrospectively determine the prognostic importance of small hypoattenuating hepatic lesions at contrast material-enhanced computed tomography (CT) in patients with breast cancer.This retrospective study was approved by the committee on human research. Written informed consent was not required. The authors retrospectively identified 153 patients with breast cancer who underwent serial abdominal CT and who did not have definite liver metastases present at initial CT. The mean age was 56 years (age range, 27-93 years). Two readers independently recorded the presence, size, and number of small (15 mm or less in diameter) hypoattenuating hepatic lesions at initial CT. Another reader independently recorded the presence or absence of definite hepatic metastases at final CT. The association between the presence, size, and number of small hypoattenuating hepatic lesions at initial CT and the subsequent development of metastases was analyzed by using Kaplan-Meier analysis.One or more small hypoattenuating hepatic lesions were seen at initial CT in 54 of 153 patients (35%). After a median follow-up of 584 days (range, 16-1827 days), definite hepatic metastases developed in 43 of 153 patients (28%), including 15 of 54 patients (28%) with hypoattenuating lesions at initial CT and 28 of 99 patients (28%) without hypoattenuating lesions at initial CT. Findings from the Kaplan-Meier analysis showed no association between the presence (P = .56), size (P = .55), or number (P = .30) of small hypoattenuating hepatic lesions at initial CT and the subsequent development of hepatic metastases.In patients with breast cancer who do not have definite hepatic metastases at initial examination, there is no evidence that small hypoattenuating hepatic lesions seen at initial CT contribute to an increased risk of subsequently developing hepatic metastases.

Abstract: Objectives To determine if the femur length of fetuses with myelomeningocele is shorter in the second and third trimesters compared with that of normal fetuses. Methods We retrospectively collected measurements of femur length, head circumference, biparietal diameter and abdominal circumference from detailed obstetric ultrasound studies performed during the second and third trimesters in 31 fetuses with myelomeningocele and 43 fetuses with no detectable anomaly. The gestational age predicted by each parameter (based on Hadlock's tables) was compared with the true gestational age (based on last menstrual period), using the ANCOVA test to determine if there was a statistically significant difference between the two groups of fetuses. Results There was no significant difference in femur length (P = 0.60) or in abdominal circumference (P = 0.85) between fetuses with myelomeningocele and normal fetuses. Fetuses with myelomeningocele did have a significantly lower biparietal diameter and head circumference (P ≤ 0.001). Conclusions Myelomeningocele is not associated with reduced femur length in the second and third trimesters, suggesting that the known postnatal lower extremity foreshortening in patients with myelomeningocele develops late in gestation or after birth.

Abstract: Aim The prevalence of abdominal wall herniation at the site of a previous temporary stoma is uncertain. This cohort study investigated the frequency of radiological abnormalities at the site of a closed diverting loop ileostomy. Method All patients in whom an ileostomy was raised and later closed during a 5-year period formed the study group. When colorectal cancer surveillance computed tomography (CT) was undertaken the images were scrutinized and graded as to defined anatomical abnormalities. Results One hundred and seventy-nine patients had an ileostomy, of which 92 were diverting. Fifty-nine (64%) were closed at various intervals (median time to closure 6 (2–22) months and 43 underwent a surveillance CT at 1–3 (median 2) years. At 1 year an abnormality (atrophy or defect) at the site of closure was seen in 16 (37%) CT scans. These were more frequent with increasing duration of follow-up. One asymptomatic hernia was detected at 2 years but there was no deterioration in the abdominal wall at 3 years when compared with that at 2 years. Conclusion Abnormalities in the abdominal wall at the site of a closed diverting ileostomy are common but true herniation is unusual. The routine use of prophylactic mesh at ileostomy closure may be unnecessary.
