Designing a synthetic simulator to teach open surgical skills for limb exploration in trauma: a qualitative study exploring the experiences and perspectives of educators and surgical trainees.

BACKGROUND: Simulation is an important adjunct to aid in the acquisition of surgical skills of surgical trainees. The simulators used to adequately enable trainees to learn, practice and be assessed in surgical skills need to be of the highest standards. This study investigates the perceived requirements of simulation and simulators used to acquire skills in limb exploratory procedures in trauma. METHODS: Semi-structured interviews were conducted with an international group of 11 surgical educators and 11 surgical trainees who had experience with surgical simulation. The interviews focused on the perceptions of simulation, the integration of simulators within a curriculum and the features of a simulator itself. Interviews were recorded, transcribed and underwent thematic analysis. RESULTS: Analysis of the perspectives of surgical educators and surgical trainees on simulated training in limb trauma surgery yielded three main themes: (1) Attitudes to simulation. (2) Implementing simulation. (3) Features of an open skills simulator. The majority felt simulation was relevant, intuitive and a good way for procedure warmup and the supplementation of surgical logbooks. They felt simulation could be improved with increased accessibility and variety of simulator options tailored to the learner. Suggested simulator features included greater fidelity, haptic feedback and more complex inbuilt scenarios. On a practical level, there was a desire for cost effectiveness, easy set up and storage. The responses of the educators and the trainees were similar and reflected similar concerns and suggestions for improvement. CONCLUSION: There is a clear positive appetite for the incorporation of simulation into limb trauma training. The findings of this will inform the optimal requirements for high quality implementation of simulation into a surgical trauma curriculum and a reference to optimal features desired in simulator or task trainer design.

Iatrogenic common bile duct injuries: Increasing complexity in the laparoscopic era: A prospective cohort study.

PURPOSE: Iatrogenic bile duct injury (BDI) is the most significant associated complication to laparoscopic cholecystectomy (LC). Little is known about the evolution of the pattern of BDI in the era of laparoscopy. The aim of the study is to assess the pattern of post-LC BDIs managed in a tertiary referral centre. METHODS: Post-LC BDI referred over two decades were studied. Demographic data, type of BDI (classified using the Strasberg System), clinical symptoms, diagnostic investigations, timing of referral, post-referral management and morbidity were analysed. The pattern of injury, associated vascular injuries rate and their management were compared over two time periods (1992-2004,2005-2014). RESULTS: 78 BDIs were referred. During the second time period Strasberg A injuries decreased from 14% to 0 and Strasberg E1increased from 4% to 23%, the rate of associated vascular injury was six time higher (3.6% versus 22.7%), more patients had an attempted repair at the index hospital (16% versus 35%) sand fewer patients could be managed without surgical intervention at the referral hospital (28% versus 4%). CONCLUSION: Complexity of referred BDIs and rate of associated vascular injuries have increased over time. These findings led to more patients managed requiring surgical intervention at the referral hospital.

Pancreatic metastasectomy: experience of the Irish National Surgical Centre for Pancreatic Cancer.

BACKGROUND: Metastatic tumours of the pancreas are rare and the optimal management of these tumours remains unclear, given the paucity of data existing in the literature. We report our experience of pancreatic metastasectomy. METHODS: Data were reviewed on all patients who underwent pancreatic resection for pathologically confirmed metastatic lesions over a consecutive 7-year period. RESULTS: Seven patients (two men and five women) underwent a pancreatectomy for a metastatic pancreatic tumour. The primary tumours were renal cell carcinoma (n = 3), colorectal carcinoma (n = 2) and leiomyosarcoma (n = 2). There was no operative mortality. Postoperative morbidities occurred in two patients. The median follow-up was 49 months (range 17-76). Overall 1- and 2-year survivals were 100 and 86 %, respectively, with a 2-year disease-free survival of 72 %. CONCLUSIONS: Our series further supports that pancreatic metastasectomy can be performed safely and achieves acceptable survival outcomes.

Pancreatectomy for metastatic disease: a systematic review.

AIM: Tumours rarely metastasise to the pancreas. While surgical resection of such metastases is believed to confer a survival benefit, there is limited data to support such management. We present a systematic review of case series of pancreatic metastasectomy and analysis of survival outcomes. METHODS: A literature search was performed using the PubMed and Cochrane databases and the reference lists of relevant articles, searching for sizeable case series of pancreatic metastasectomy with curative intent. Data extracted included basic demographics, histological primary tumour, presentation, operative management, complications and survival, while the MINORS index was used to assess study quality. RESULTS: 18 studies were found which met our inclusion criteria, involving 399 patients. Renal cell carcinoma (RCC) was the commonest malignancy metastasising to the pancreas, responsible for 62.6% of cases, followed by sarcoma (7.2%) and colorectal carcinoma (6.2%). While survival data was not uniformly reported, the median survival post-metastasectomy was 50.2 months, with a one-year survival of 86.81% and five-year survival of 50.02%. Median survival for RCC was 71.7 months with 70.4% five-year survival. Median survival was similar in patients with synchronous and metachronous pancreatic metastases, but patients with additional extrapancreatic metastases had a significantly shorter survival than patients with isolated pancreatic metastases (26 versus 45 months). Study quality was poor, with a median MINORS score of 10/16. CONCLUSIONS: Within the limitations of a review of non-randomised case series, it would appear that pancreatic metastasectomy confers a survival benefit in selected patients. Better evidence is required, but may prove difficult to acquire.

Hyaline vascular Castleman's disease involving the biliary tract.

We report a case of Castleman's Disease (CD), hyaline vascular subtype involving the biliary tract with obstruction. A 43 year old man presented with a 5 week history of abdominal and back pain with biliary obstructive symptoms. He was jaundiced with persistently high LFTs. Radiological investigation revealed a stricture in the extrahepatic biliary tract. The clinical impression at the time was of sclerosing cholangitis with bile duct cholangiocarcinoma. A Whipple's procedure was performed. Histology and immunohistochemistry supported the histologic diagnosis of CD of hyaline vascular subtype. There was no evidence of disease elsewhere and the patient was disease free after a 6 year follow-up. Our case describes the hyaline vascular subtype of CD, a relatively rare disease occurring in a previously undescribed location.

Higher surgical training opportunities in the general hospital setting; getting the balance right.

BACKGROUND: The general hospital can play an important role in training of higher surgical trainees (HSTs) in Ireland and abroad. Training opportunities in such a setting have not been closely analysed to date. AIMS: The aim of this study was to quantify operative exposure for HSTs over a 5-year period in a single institution. METHODS: Analysis of electronic training logbooks (over a 5-year period, 2007-2012) was performed for general surgery trainees on the higher surgical training programme in Ireland. The most commonly performed adult and paediatric procedures per trainee, per year were analysed. RESULTS: Standard general surgery operations such as herniae (average 58, range 32-86) and cholecystectomy (average 60, range 49-72) ranked highly in each logbook. The most frequently performed emergency operations were appendicectomy (average 45, range 33-53) and laparotomy for acute abdomen (average 48, range 10-79). Paediatric surgical experience included appendicectomy, circumcision, orchidopexy and hernia/hydrocoele repair. Overall, the procedure most commonly performed in the adult setting was endoscopy, with each trainee recording an average of 116 (range 98-132) oesophagogastroduodenoscopies and 284 (range 227-354) colonoscopies. CONCLUSIONS: General hospitals continue to play a major role in the training of higher surgical trainees. Analysis of the electronic logbooks over a 5-year period reveals the high volume of procedures available to trainees in a non-specialist centre. Such training opportunities are invaluable in the context of changing work practices and limited resources.

The surgical safety checklist survey: a national perspective on patient safety.

BACKGROUND: In 2008, the World Health Organisation (WHO) recommended practices to ensure the safety of patients worldwide. This led to the development of the Surgical Safety Checklist (SSC). Ireland has endorsed the SSC ( www.hiqa.ie/press-release/2008-06-17-health-information-and-quality-authority-launches-world-health-organization , 10). OBJECTIVES: We aimed to determine (i) whether SSC is being implemented, (ii) whether it promotes a safer surgical environment and (iii) identify problems associated with its introduction and on-going implementation. METHODS: All hospitals in Ireland with operating departments (n = 61) were invited to participate in an online survey. RESULTS: The response rate was 67 %. The WHO SSC or modified version is in place in 78 % (mean time: 20 months) of operating departments that responded. Partaking in Time Out as a team was reported as occurring in 57 % of cases. Greater than 60 % of respondents reported that the SSC was difficult to introduce and implement and that its introduction was time consuming. Further training in using the SSC was reported as desirable by 84 % of respondents. The introduction of the SSC was reported to be associated with an improvement in team communication (72 %), a positive change in team behaviour (63 %), an increase in the consistency of patient care (82 %) and a positive culture of safety in theatre (81 %). CONCLUSION: The SSC has not been implemented throughout all operating departments in Ireland. Where it has been introduced there has been a perceived positive change in safety culture. However, overall greater education, endorsement, teamwork, and communication will be required to optimise the potential benefits associated with this safety instrument. In order to properly determine the benefit of the SSC following its implementation, a formal audit of morbidity and mortality is required.

Bench and bedside? Surgeons' views on the role of research in surgical training.

AIMS: Internationally, surgical training is facing the challenge of balancing research and clinical experience in the context of reduced working hours. This study aimed to investigate trainees and trainers' views on surgeons participating in full-time research during surgical training. METHODS: An anonymous voluntary survey was conducted of surgical trainers and trainees in two training systems. To examine surgeons' views across two different training schemes, surgeons were surveyed in Ireland (Royal College of Surgeons in Ireland) and in a Canadian centre (University of Toronto) between January 2009 and September 2010 (n = 397 respondents). RESULTS: The majority of respondents felt that time spent in research by trainees was important for surgery as a specialty, while 65 % felt that research was important for surgical trainees (trainers 79 %, trainees 60 %, p = 0.001). A higher proportion of Canadian surgeons reported that they enjoyed their time spent in research, compared to Irish surgeons (84 vs. 66 %, p = 0.05). Financial worries and loss of clinical time were common demotivating factors. Full-time research was more popular than part-time options to obtain a post-graduate degree. CONCLUSIONS: Most agree that research remains an important component of surgical training. However, there are significant differences in opinion among surgeons in different countries on the precise role and structure of research in surgical training.

Towards continuous improvement of endoscopy standards: validation of a colonoscopy assessment form.

AIM: The assessment of procedural colonoscopy skills is important and topical. The aim of this study was to develop and validate a competency-based colonoscopy assessment form that would be easy to use, suitable for the assessment of junior and senior endoscopists and potentially a useful instrument to detect differences in performance standards following different training interventions. METHOD: A standardized assessment form was developed incorporating a checklist with dichotomous yes/no responses and a global assessment section incorporating several different elements. This form was used prospectively to evaluate colonoscopy cases during the period of the study in several university teaching hospitals. Results were analysed using ANOVA with Bonferroni corrections for post hoc analysis. RESULTS: Eighty-one procedures were assessed, performed by eight consultant and 19 trainee endoscopists. There were no serious errors. When divided into three groups based on previous experience (novice, intermediate and expert) the assessment form demonstrated statistically significant differences between all three groups (P<0.05). When separate elements were taken into account, the global assessment section was a better discriminator of skill level than the checklist. CONCLUSION: This form is a valid, easy-to-use assessment method. We intend to use it to assess the value of simulator training in trainee endoscopists. It also has the potential to be a useful training tool when feedback is given to the trainee.

Video gaming enhances psychomotor skills but not visuospatial and perceptual abilities in surgical trainees.

INTRODUCTION: There is considerable interest in the identification and assessment of underlying aptitudes or innate abilities that could potentially predict excellence in the technical aspects of operating. However, before the assessment of innate abilities is introduced for high-stakes assessment (such as competitive selection into surgical training programs), it is essential to determine that these abilities are stable and unchanging and are not influenced by other factors, such as the use of video games. The aim of this study was to investigate whether experience playing video games will predict psychomotor performance on a laparoscopic simulator or scores on tests of visuospatial and perceptual abilities, and to examine the correlation, if any, between these innate abilities. METHODS: Institutional ethical approval was obtained. Thirty-eight undergraduate medical students with no previous surgical experience were recruited. All participants completed a self-reported questionnaire that asked them to detail their video game experience. They then underwent assessment of their psychomotor, visuospatial, and perceptual abilities using previously validated tests. The results were analyzed using independent samples t tests to compare means and linear regression curves for subsequent analysis. RESULTS: Students who played video games for at least 7 hours per week demonstrated significantly better psychomotor skills than students who did not play video games regularly. However, there was no difference on measures of visuospatial and perceptual abilities. There was no correlation between psychomotor tests and visuospatial or perceptual tests. CONCLUSIONS: Regular video gaming correlates positively with psychomotor ability, but it does not seem to influence visuospatial or perceptual ability. This study suggests that video game experience might be beneficial to a future career in surgery. It also suggests that relevant surgical skills may be gained usefully outside the operating room in activities that are not related to surgery.

Inflammatory pseudotumours of the liver--role of dynamic MRI scan and surgical exploration.

Inflammatory pseudotumours of the liver are extremely rare benign lesions. They were first described by Pack and Baker in 1953. They usually present with raised inflammatory markers and nonspecific abdominal symptoms. Most of these lesions are picked up incidentally on ultrasound scans. Diagnosis of these lesions poses a dilemma and a challenge due to their radiological similarities to other liver lesions such as hepatocellular carcinoma HCC. In this article we describe our experience in its diagnosis and management.

Coping with stress in surgery: the difficulty of measuring non-technical skills.

BACKGROUND: Non-technical skills are relevant to surgical performance but are difficult to quantify. The aim of this study was to investigate the relationship between self-efficacy, which is a measure of stress-coping ability, and surgical performance. METHODS: Two hundred and sixteen basic surgical trainees were assessed on their performance of three bench model-type open and laparoscopic surgical tasks. They also completed a 10-item General Self-Efficacy (GSE) questionnaire to assess their stress-coping abilities. Their assessment scores were correlated with the GSE scores. RESULTS: The mean GSE score of 31.39 was higher than the recorded population norms. There was no significant correlation between GSE and surgical performance for open or laparoscopic tasks. CONCLUSION: Junior surgical trainees have high self-belief scores, but these abilities are difficult to measure and quantify. More refined methods may be necessary to measure non-technical skills relevant to surgery.

Hepatic transplantation outcomes for carefully selected cirrhotic patients with hepatocellular carcinoma: experience at a small- to medium-volume centre.

BACKGROUND: Hepatic transplantation outcomes for cirrhotic patients with hepatocellular carcinoma (HCC) at a small- to medium-volume centre are not fully known due to relative novelty of patient selection criteria. AIM: To determine hepatic transplantation outcomes for HCC at a small- to medium-volume centre. Patients and methods Hepatocellular carcinoma patients were listed for transplantation according to the International Guideline and further categorized as those fulfilling or exceeding Milan or University of San Francisco (UCSF) criteria on explanted liver morphology. Outcomes including mortality, retransplantation, and tumour recurrence rate were analysed. RESULTS: Twenty-six patients had HCC and on explanted liver morphology, Milan and UCSF criteria met 15 and 18 patients, respectively. Patients and graft survival at 3 months, 1 and 5 years were 100, 96, 84, and 88, 84, 77%, respectively. Outcomes favoured Milan criteria but did not reach statistical significance. CONCLUSIONS: Hepatic transplantation for HCC at a small-to medium-volume transplant centre had comparable survival outcomes to high-volume centres.

Significant influence of the primary liver disease on the outcomes of hepatic retransplantation.

BACKGROUND: There are many indications for hepatic retransplantation. AIM: To identify factors influencing retransplantation needs and outcomes. PATIENTS AND METHODS: Retransplantation records from January 1993 to March 2005 were analysed. Patient and disease characteristics and survival outcomes for retransplantation were compared between various groups. RESULTS: Totally, 286 primary and 42 hepatic retransplantations were performed. Retransplantation indications included primary sclerosing cholangitis (PSC), primary biliary cirrhosis, chronic hepatitis C (HCV), chronic active hepatitis (CAH), and alcohol-related disease. Mean follow-up post-retransplantation was 31 +/- 9 months. Actuarial patient survival at 3 months, 1 year, 3 years, 5 years, and at the end of study was 71.4, 69, 59.5, 54.7, and 50%, respectively. Early and late retransplantation had 1-year survival of 73 and 68.5%, respectively. Retransplantation need was significantly higher for PSC, HCV, and CAH. CONCLUSIONS: Hepatic retransplantation remains a successful salvage option for transplant complications; however, its need is significantly influenced by the primary liver disease.

The "flying" bile duct: avulsion of the common bile duct in a plane crash survivor.

Blunt trauma is an unusual cause of extrahepatic bile duct injury. This is a case of a 51-year-old gentleman who sustained a significant seatbelt injury in a plane crash. Laparotomy, performed due to persistent abdominal pain, revealed that the common bile duct (CBD) was completely avulsed from the duodenum. Following insertion of drains and transfer to a hepatobiliary centre, the devascularised CBD was excised and replaced with a roux-en-y hepaticojejunostomy. Necrotic tissue was debrided from the pancreatic head. A persistent bile leak developed from the sub-hepatic drain. Repeat laparotomy revealed a bile leak from small ducts on the liver surface. Ligation of the ducts and bioglue sealing of the area were successfully performed. Subsequent to this a pancreatic fistula developed from the main pancreatic duct, which has since resolved. This unusual case illustrates the need for prompt recognition and early repair to optimise outcomes in traumatic CBD injury.
