    Emergency repair of complicated abdominal wall hernias may be associated with worsen outcome and a significant rate of postoperative complications. There is no consensus on management of complicated abdominal hernias. The main matter of debate is about the use of mesh in case of intestinal resection and the type of mesh to be used. Wound infection is the most common complication encountered and represents an immense burden especially in the presence of a mesh. The recurrence rate is an important topic that influences the final outcome. A World Society of Emergency Surgery (WSES) Consensus Conference was held in Bergamo in July 2013 with the aim to define recommendations for emergency repair of abdominal wall hernias in adults. This document represents the executive summary of the consensus conference approved by a WSES expert panel. In 2016, the guidelines have been revised and updated according to the most recent available literature.

  • Breast cancer risk assessment and screening - Is it a persistent problem in a rural population?

    Johnston, Alison; Neary, Shane; Sugrue, Michael; Department of Breast Surgery, Breast Centre North West, Letterkenny University Hospital, Donegal Clinical Research Academy, Ireland (Remedy Publications LLC, 2017-08-09)
    Trend analysis of breast screening uptake in those meeting screening criteria that were newly diagnosed with breast cancer. Retrospective review of all breast cancer patients diagnosed between 2010 and 2014. Patients’ demographics, screening, risk assessment, pathological stages and surgical treatment utilization were recorded. 150 patients, mean ages 55.4 ± 10.2 years (range 29–90), were studied. Overall 65/150 (43.3%) had optimal screening pre cancer diagnosis and 85/150 (56.7%) suboptimal. The trend in optimal screening improved from 30% to 60% over the study period. The mean overall tumour size (excluding DCIS patients) in 131 patients was 32.8 mm; 26.9 mm in optimally and 38.5 mm in the suboptimally screened groups (p = 0.06 x2 df8). 113/150 (75.3%) diagnosed with early stage breast cancer and 37/150 (24.7%) late stage. Principally late stage at diagnosis was within the group with suboptimal screening; 100%, 100%, 63.6%, 75% and 60% respectively for years 2010–2014. This study identified improving trends in compliance with international screening and risk assessment guidelines. Failure to screen results in more advanced disease; further public health measures to engage appropriate screening may improve stage at presentation and breast cancer outcomes.
  • Targeting breast cancer outcomes-what about the primary relatives?

    Johnston, Alison; Sugrue, Michael (Wiley-Blackwell, 2017-07)
    Up to 65% of newly diagnosed breast cancer patients had not been screened correctly before diagnosis resulting in increased stage of cancer at presentation. This study assessed whether their primary relatives are, in turn, assessed appropriately.
  • 2016 WSES guidelines on acute calculous cholecystitis.

    Ansaloni, L; Pisano, M; Coccolini, F; Peitzmann, A B; Fingerhut, A; Catena, F; Agresta, F; Allegri, A; Bailey, I; Balogh, Z J; Bendinelli, C; Biffl, W; Bonavina, L; Borzellino, G; Brunetti, F; Burlew, C C; Camapanelli, G; Campanile, F C; Ceresoli, M; Chiara, O; Civil, I; Coimbra, R; De Moya, M; Di Saverio, S; Fraga, G P; Gupta, S; Kashuk, J; Kelly, M D; Koka, V; Jeekel, H; Latifi, R; Leppaniemi, A; Maier, R V; Marzi, I; Moore, F; Piazzalunga, D; Sakakushev, B; Sartelli, M; Scalea, T; Stahel, P F; Taviloglu, K; Tugnoli, G; Uraneus, S; Velmahos, G C; Wani, I; Weber, D G; Viale, P; Sugrue, M; Ivatury, R; Kluger, Y; Gurusamy, K S; Moore, E E (World journal of emergency surgery : WJES, 2016)
    Acute calculus cholecystitis is a very common disease with several area of uncertainty. The World Society of Emergency Surgery developed extensive guidelines in order to cover grey areas. The diagnostic criteria, the antimicrobial therapy, the evaluation of associated common bile duct stones, the identification of "high risk" patients, the surgical timing, the type of surgery, and the alternatives to surgery are discussed. Moreover the algorithm is proposed: as soon as diagnosis is made and after the evaluation of choledocholitiasis risk, laparoscopic cholecystectomy should be offered to all patients exception of those with high risk of morbidity or mortality. These Guidelines must be considered as an adjunctive tool for decision but they are not substitute of the clinical judgement for the individual patient.
  • A user's guide to intra-abdominal pressure measurement.

    Sugrue, Michael; De Waele, Jan J; De Keulenaer, Bart L; Roberts, Derek J; Malbrain, Manu L N G (Anaesthesiology intensive therapy, 2015)
    The intra-abdominal pressure (IAP) measurement is a key to diagnosing and managing critically ill medical and surgical patients. There are an increasing number of techniques that allow us to measure the IAP at the bedside. This paper reviews these techniques. IAP should be measured at end-expiration, with the patient in the supine position and ensuring that there is no abdominal muscle activity. The intravesicular IAP measurement is convenient and considered the gold standard. The level where the mid-axillary line crosses the iliac crest is the recommended zero reference for the transvesicular IAP measurement; moreover, marking this level on the patient increases reproducibility. Protocols for IAP measurement should be developed for each ICU based on the locally available tools and equipment. IAP measurement techniques are safe, reproducible and accurate and do not increase the risk of urinary tract infection. Continuous IAP measurement may offer benefits in specific situations in the future. In conclusion, the IAP measurement is a reliable and essential adjunct to the management of patients at risk of intra-abdominal hypertension.
  • How to deal with an open abdomen?

    De Waele, Jan J; Kaplan, Mark; Sugrue, Michael; Sibaja, Pablo; Björck, Martin (Anaesthesiology intensive therapy, 2015)
    Appropriate open abdomen treatment is one of the key elements in the management of patients who require decompressive laparotomy or in whom the abdomen is left open prophylactically. Apart from fluid control and protection from external injury, fluid evacuation and facilitation of early closure are now the goals of open abdomen treatment. Abdominal negative pressure therapy has emerged as the most appropriate method to reach these goals. Especially when combined with strategies that allow progressive approximation of the fascial edges, high closure rates can be obtained. Intra-abdominal pressure measurement can be used to guide the surgical strategy and continued attention to intra-abdominal hypertension is necessary. This paper reviews recent advances as well as identifying the remaining challenges in patients requiring open abdomen treatment. The new classification system of the open abdomen is an important tool to use when comparing the efficacy of different strategies, as well as different systems of temporary abdominal closure.
  • The Centricity Score: A Novel Measurement to Aid in Conservative Breast Cancer Surgery

    Sugrue, Ryan; McGowan, Katherine; McNamara, Cillian; Sugrue, Michael (Advances in Breast Cancer Research, 2014-10)
    Introduction: This study describes an intra-operative scoring system to advise the surgeon of the centricity of the tumour in the excised specimen. Methods: Spatial estimations were prospectively made in 10 consecutive patients undergoing wide local excision (WLE) using Bioptics intra-operative digital specimen imaging. The centricity score was defined as 100 – (ICD/SD × 100), where ICD is the inter-centre distance between the specimen’s centre and the tumour’s centre. Results: 10 patients with invasive breast cancer (T1b to T4a), mean age 56 years (range 44 - 71) were studied. The mean tumour and specimen diameter was 24 mm ± 10 (range 12 - 48) and 101 mm ± 22 (range 64 - 140). The mean centricity score was 86 ± 9 (range 65 - 95). Conclusion: This study successfully describes an intraoperative radiological spatial scoring system for patients undergoing WLE. Tumours were well centered in specimens with an overall score of 86/100. The centricity score could be used to guide excision and potentially set benchmarks for conservative breast surgery.
  • Failure to engage in breast screening and risk assessment results in more advanced stage at diagnosis

    Johnston, Alison; Curran, Sharon; Sugrue, Michael (Scientific Research Publishing, 2015-04-09)
    Abstract Background: Although well established, population based screening and family risk assessment for breast cancer have come under increasing scrutiny. The concept of over diagnosis is increasingly cited in cancer publications. This study assessed the impact of failure to screen or risk assess patients attending with a new diagnosis of breast cancer. Methods: A retrospective review was undertaken of 200 consecutive patients diagnosed with breast cancer between January 2010 and September 2012 at Letterkenny Hospital. Appropriate screening was defined as biennial in those aged 50 - 66 and in those 40 - 49 with moderate/high family history risk (NICE criteria or IBIS criteria). Patient demographics, screening history, diagnosis date and stage (TNM) were documented. Patients with previous breast cancer were not included (n = 17). Results: 200 consecutive patients, whose mean age was 61 (range 28 - 99), were studied. 112/200 (56%) met no criteria for screening or family history assessment, and 88/200 (44%) met criteria for either screening (in 56) or family history assessment (in 32). 61/88 (69.3%) meeting criteria did not have a mammogram or risk assessment. The stage of breast cancer was significantly earlier in those screened appropriately, with early stage cancer in n = 111/139 (79.9 %) and late in n = 28/139 (20.1%), compared with 38/61 (62.3%) and 23/61 (37.7%) in those failing to be screened appropriately (p = 0.01 χ2 df1). Conclusion: Failure to engage in breast screening and risk assessment resulted in more advanced stage at diagnosis.
  • European undergraduate curriculum in geriatric medicine developed using an international modified Delphi technique.

    Masud, Tahir; Blundell, Adrian; Gordon, Adam Lee; Mulpeter, Ken; Roller, Regina; Singler, Katrin; Goeldlin, Adrian; Stuck, Andreas (Oxford University Press, 2014-09)
    the rise in the number of older, frail adults necessitates that future doctors are adequately trained in the skills of geriatric medicine. Few countries have dedicated curricula in geriatric medicine at the undergraduate level. The aim of this project was to develop a consensus among geriatricians on a curriculum with the minimal requirements that a medical student should achieve by the end of medical school.

    Hogan, Mark; Nangle, Niamh; Morrison, Todd G; McGuire, Brian E; School of Psychology, National University of Ireland, Galway, Ireland. markf.hogan@hse.ie (2013)
    Quality-of-life (QoL) measures may be useful in quantifying the personal impact of an acquired brain injury and as an indicator of the effectiveness of service provision. This study investigated the validity of the patient generated index (PGI) as a measure of QoL with a sample of adults who had sustained a severe traumatic brain injury.
  • Rigid or flexible sigmoidoscopy in colorectal clinics? Appraisal through a systematic review and meta-analysis.

    Ahmad, Nasir Zaheer; Ahmed, Aftab; Letterkenny General Hospital, Letterkenny, County Donegal, Ireland. nasirzahmad@gmail.com (2012-06)
    Rigid sigmoidoscopy is sometimes performed at first presentation in colorectal clinics. We assessed the feasibility of flexible sigmoidoscopy in similar situations by comparing it with rigid sigmoidoscopy as a first investigative tool.
  • The Impact of Chronic Obstructive Pulmonary Disease and Smoking on Mortality and Kidney Transplantation in End-Stage Kidney Disease.

    Kent, Brian D; Eltayeb, Elhadi E; Woodman, Alastair; Mutwali, Arif; Nguyen, Hoang T; Stack, Austin G; Regional Kidney Centre, Letterkenny General Hospital, Health Services Executive-West, Donegal, Ireland. (2012-09-07)
    Background: Chronic obstructive pulmonary disease (COPD) and tobacco use are leading causes of morbidity and mortality. The prevalence and clinical impact of COPD on mortality and kidney transplantation among patients who begin dialysis therapy is unclear. Methods: We explored the clinical impact of COPD and continued tobacco use on overall mortality and kidney transplantation in a national cohort study of US dialysis patients. National data on all dialysis patients (n = 769,984), incident between May 1995 and December 2004 and followed until October 31, 2006, were analyzed from the United States Renal Data System. Prevalence and period trends were determined while multivariable Cox regression evaluated relative hazard ratios (RR) for death and kidney transplantation. Results: The prevalence of COPD was 7.5% overall and increased from 6.7 to 8.1% from 1995-2004. COPD correlated significantly with older age, cardiovascular conditions, cancer, malnutrition, poor functional status, and tobacco use. Adjusted mortality risks were significantly higher for patients with COPD (RR = 1.20, 95% CI 1.18-1.21), especially among current smokers (RR = 1.28, 95% CI 1.25-1.32), and varied inversely with advancing age. In contrast, the adjusted risks of kidney transplantation were significantly lower for patients with COPD (RR = 0.47, 95% CI 0.41-0.54, for smokers and RR = 0.54, 95% CI 0.50-0.58, for non-smokers) than without COPD [RR = 0.72, 95% CI 0.70-0.75, for smokers and RR = 1.00 for non-smokers (referent category)]. Conclusions: Patients with COPD who begin dialysis therapy in the US experience higher mortality and lower rates of kidney transplantation, outcomes that are far worse among current smokers.

    Chemotherapy-induced nausea and vomiting are symptoms that cause major concern to oncology patients. This article explores the types of nausea and vomiting in the context of chemotherapy, and discusses their pathogenesis and management.
  • Cigarette use and cardiovascular risk in chronic kidney disease: an unappreciated modifiable lifestyle risk factor.

    Stack, Austin G; Murthy, Bhamidipati V R; Regional Kidney Centre, Department of Medicine, Letterkenny General Hospital,, Health Services Executive, County Donegal, Ireland. austin.stack@hse.ie (2012-01-31)
    Tobacco use is a major modifiable cardiovascular risk factor in the general population and contributes to excess cardiovascular risk. Emerging evidence from large-scale observational studies suggests that continued tobacco use is also an independent cardiovascular risk factor among patients with chronic kidney disease (CKD). The benefits of smoking cessation programs on improving the heath status of patients and reducing mortality are unequivocal in the general population. Despite this, there has been little effort in pursuing tobacco cessation programs in dialysis cohorts or those with lesser degrees of kidney impairment. Most of our attention to date has focused on the development of "kidney-specific" interventions that reduce rates of renal disease progression and improve dialysis outcomes. The purpose of this current review is to describe the epidemiology of tobacco use among patients with CKD, draw attention to its negative impact on cardiovascular morbidity and mortality, and finally highlight potential strategies for successful intervention. We hope that this study heightens the importance of tobacco use in CKD, stimulates renewed interest in the barriers and challenges that exist in achieving smoking cessation, and endorses the efficacy of intervention strategies and the immeasurable benefits of quitting on cardiovascular and noncardiovascular outcomes.
  • Community-based health efforts for the prevention of falls in the elderly.

    Hanley, Alan; Silke, Carmel; Murphy, John; Department of Medicine, Letterkenny General Hospital, Letterkenny, Co Donegal,, Ireland. alan.hanley@gmail.com (2012-01-31)
    Falls are a major public health problem in the elderly population. The associated health care cost is great. It has therefore become an important public health matter to evaluate those interventions that might be effective in reducing the risk of falls. Risk factors that predict an increased risk of falling are described. We discuss interventions that can be employed in the community to reduce the risk of falls and associated injuries by discipline, including physiotherapy, occupational therapy, and physician-led interventions. We also discuss the cost-effectiveness of such interventions.
  • Survival trends of US dialysis patients with heart failure: 1995 to 2005.

    Stack, Austin G; Mohammed, Amir; Hanley, Alan; Mutwali, Arif; Nguyen, Hoang; Regional Kidney Centre, Department of Medicine, Letterkenny General Hospital,, Letterkenny, Donegal, Ireland. Austin.Stack@hse.ie (2012-01-31)
    BACKGROUND AND OBJECTIVES: Congestive heart failure (CHF) is a major risk factor for death in end-stage kidney disease; however, data on prevalence and survival trends are limited. The objective of this study was to determine the prevalence and mortality effect of CHF in successive incident dialysis cohorts. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This was a population-based cohort of incident US dialysis patients (n = 926,298) from 1995 to 2005. Age- and gender-specific prevalence of CHF was determined by incident year, whereas temporal trends in mortality were compared using multivariable Cox regression. RESULTS: The prevalence of CHF was significantly higher in women than men and in older than younger patients, but it did not change over time in men (range 28% to 33%) or women (range 33% to 36%). From 1995 to 2005, incident death rates decreased for younger men (70 years). For women, the pattern was similar but less impressive. During this period, the adjusted mortality risks (relative risk [RR]) from CHF decreased in men (from RR = 1.06 95% Confidence intervals (CI) 1.02-1.11 in 1995 to 0.91 95% CI 0.87-0.96 in 2005) and women (from RR = 1.06 95% CI 1.01-1.10 in 1995 to 0.90 95% CI 0.85-0.95 in 2005 compared with referent year 2000; RR = 1.00). The reduction in mortality over time was greater for younger than older patients (20% to 30% versus 5% to 10% decrease per decade). CONCLUSIONS: Although CHF remains a common condition at dialysis initiation, mortality risks in US patients have declined from 1995 to 2005.
