RESUMEN
BACKGROUND: Future innovations in science and technology with an impact on multimodal breast cancer management from a surgical perspective are discussed in this narrative review. The work was undertaken in response to the Commission on the Future of Surgery project initiated by the Royal College of Surgeons of England. METHODS: Expert opinion was sought around themes of surgical de-escalation, reduction in treatment morbidities, and improving the accuracy of breast-conserving surgery in terms of margin status. There was emphasis on how the primacy of surgical excision in an era of oncoplastic and reconstructive surgery is increasingly being challenged, with more effective systemic therapies that target residual disease burden, and permit response-adapted approaches to both breast and axillary surgery. RESULTS: Technologies for intraoperative margin assessment can potentially half re-excision rates after breast-conserving surgery, and sentinel lymph node biopsy will become a therapeutic procedure for many patients with node-positive disease treated either with surgery or chemotherapy as the primary modality. Genomic profiling of tumours can aid in the selection of patients for neoadjuvant and adjuvant therapies as well as prevention strategies. Molecular subtypes are predictive of response to induction therapies and reductive approaches to surgery in the breast or axilla. CONCLUSION: Treatments are increasingly being tailored and based on improved understanding of tumour biology and relevant biomarkers to determine absolute benefit and permit delivery of cost-effective healthcare. Patient involvement is crucial for breast cancer studies to ensure relevance and outcome measures that are objective, meaningful, and patient-centred.
This article describes how future innovations in science and technology influence the management of breast cancer from a surgical perspective. This work was undertaken in response to the Commission on the Future of Surgery project initiated by the Royal College of Surgeons of England.

BACKGROUND: Surgeons traditionally aim to reduce mistakes in healthcare through repeated training and advancement of surgical technology. Recently, performance-enhancing interventions such as neurostimulation are emerging which may offset errors in surgical practice. METHODS: Use of transcranial direct-current stimulation (tDCS), a novel neuroenhancement technique that has been applied to surgeons to improve surgical technical performance, was reviewed. Evidence supporting tDCS improvements in motor and cognitive performance outside of the field of surgery was assessed and correlated with emerging research investigating tDCS in the surgical setting and potential applications to wider aspects of healthcare. Ethical considerations and future implications of using tDCS in surgical training and perioperatively are also discussed. RESULTS: Outside of surgery, tDCS studies demonstrate improved motor performance with regards to reaction time, task completion, strength and fatigue, while also suggesting enhanced cognitive function through multitasking, vigilance and attention assessments. In surgery, current research has demonstrated improved performance in open knot-tying, laparoscopic and robotic skills while also offsetting subjective temporal demands. However, a number of ethical issues arise from the potential application of tDCS in surgery in the form of safety, coercion, distributive justice and fairness, all of which must be considered prior to implementation. CONCLUSION: Neuroenhancement may improve motor and cognitive skills in healthcare professions with impact on patient safety. Implementation will require accurate protocols and regulations to balance benefits with the associated ethical dilemmas, and to direct safe use for clinicians and patients.
ANTECEDENTES: Los cirujanos tratan de reducir sus errores durante la atención médica mediante el entrenamiento reiterado y los avances tecnológicos. Recientemente, han surgido otras opciones para mejorar el rendimiento, como la neuroestimulación que puede subsanar los errores en la práctica quirúrgica. MÉTODOS: Se revisó la utilización de la estimulación transcraneal de corriente directa (transcranial direct-current stimulation, tDCS), una técnica de estimulación neurológica que se ha aplicado a cirujanos para mejorar su rendimiento técnico. Se revisaron las evidencias que dan soporte a la mejoría en el rendimiento motor y cognitivo tras tDCS en otros ámbitos más allá de la cirugía y se correlacionó con datos recientes obtenidos en el entorno quirúrgico y sus posibles aplicaciones a otras áreas de la atención médica. También se discuten aspectos éticos y las implicaciones que la utilización de la tDCS pudiera tener en el entrenamiento quirúrgico y perioperatorio. RESULTADOS: Al margen de la cirugía, los estudios de tDCS demuestran una mejoría en el rendimiento motor medido por el tiempo de reacción, de finalización de tareas, de fuerza y la fatiga, así como también sugieren un incremento de la función cognitiva a través de evaluaciones multitarea, de vigilancia y de atención. En cirugía, la investigación actual ha demostrado una mejoría en el rendimiento para la realización de nudos abiertos, habilidades laparoscópicas y robóticas, mientras también contrarresta las exigencias subjetivas materiales. Sin embargo, surgen aspectos éticos ante la posible aplicación de la tDCS en cirugía, como son la seguridad, la coerción, la justicia distributiva y la equidad, situaciones que deben considerarse antes de su implementación. CONCLUSIÓN: La estimulación neurológica puede mejorar las habilidades motoras y cognitivas de los profesionales sanitarios con repercusión en la seguridad del paciente. Su implementación requerirá de protocolos y regulaciones específicas para equilibrar los beneficios con los dilemas éticos asociados y garantizar su seguridad para médicos y pacientes.

BACKGROUND: High rates of reoperation following breast-conserving surgery (BCS) for positive margins are associated with costs to healthcare providers. The aim was to assess the quality of evidence on reported re-excision costs and compare the direct patient-level costs between patients undergoing successful BCS versus reoperations after BCS. METHODS: The study used data from women who had BCS with or without reoperation at a single institution between April 2015 and March 2016. A systematic review of health economic analysis in BCS was conducted and scored using the Quality of Health Economic Studies (QHES) instrument. Financial data were retrieved using the Patient-Level Information and Costing Systems (PLICS) for patients. Exchange rates used were: US $1 = £0·75, £1 = 1·14 and US $1 = 0·85. RESULTS: The median QHES score was 47 (i.q.r. 32·5-79). Only two of nine studies scored in the upper QHES quartile (score at least 75). Costs of initial lumpectomy and reoperation were in the range US $1234-11786 and $655-9136 respectively. Over a 12-month interval, 153 patients had definitive BCS and 59 patients underwent reoperation. The median cost of reoperations after BCS (59 patients) was £4511 (range 1752-18 019), representing an additional £2136 per patient compared with BCS without reoperation (P < 0·001). CONCLUSION: The systematic review demonstrated variation in methodological approach to cost estimates and a paucity of high-quality cost estimate studies for reoperations. Extrapolating local PLICS data to a national level suggests that getting BCS right first time could result in substantial savings.

BACKGROUND: Surgical subspecialization has resulted in mastitis and breast abscesses being managed with unnecessary admission to hospital, prolonged inpatient stay, variable antibiotic prescribing, incision and drainage rather than percutaneous aspiration, and loss to specialist follow-up. The objective was to evaluate a best-practice algorithm with the aim of improving management of mastitis and breast abscesses across a multisite NHS Trust. The focus was on uniformity of antibiotic prescribing, ultrasound assessment, admission rates, length of hospital stay, intervention by aspiration or incision and drainage, and specialist follow-up. METHODS: Management was initially evaluated in a retrospective cohort (phase I) and subsequently compared with that in two prospective cohorts after introduction of a breast abscess and mastitis pathway. One prospective cohort was analysed immediately after introduction of the pathway (phase II), and the second was used to assess the sustainability of the quality improvements (phase III). The overall impact of the pathway was assessed by comparing data from phase I with combined data from phases II and III; results from phases II and III were compared to judge sustainability. RESULTS: Fifty-three patients were included in phase I, 61 in phase II and 80 in phase III. The management pathway and referral pro forma improved compliance with antibiotic guidelines from 34 per cent to 58·2 per cent overall (phases II and III) after implementation (P = 0·003). The improvement was maintained between phases II and III (54 and 61 per cent respectively; P = 0·684). Ultrasound assessment increased from 38 to 77·3 per cent overall (P < 0·001), in a sustained manner (75 and 79 per cent in phases II and III respectively; P = 0·894). Reductions in rates of incision and drainage (from 8 to 0·7 per cent overall; P = 0·007) were maintained (0 per cent in phase II versus 1 per cent in phase III; P = 0·381). Specialist follow-up improved consistently from 43 to 95·7 per cent overall (P < 0·001), 92 per cent in phase II and 99 per cent in phase III (P = 0·120). Rates of hospital admission and median length of stay were not significantly reduced after implementation of the pathway. CONCLUSION: A standardized approach to mastitis and breast abscess reduced undesirable practice variation, with sustained improvements in process and patient outcomes.

INTRODUCTION: Completion of hand-written consent forms for surgical procedures may suffer from missing or inaccurate information, poor legibility and high variability. We audited the completion of hand-written consent forms and trialled a web-based application to generate modifiable, procedure-specific consent forms. METHODS: The investigation comprised two phases at separate UK hospitals. In phase one, the completion of individual responses in hand-written consent forms for a variety of procedures were prospectively audited. Responses were categorised into three domains (patient details, procedure details and patient sign-off) that were considered "failed" if a contained element was not correct and legible. Phase two was confined to a breast surgical unit where hand-written consent forms were assessed as for phase one and interrogated for missing complications by two independent experts. An electronic consent platform was introduced and electronically-produced consent forms assessed. RESULTS: In phase one, 99 hand-written consent forms were assessed and the domain failure rates were: patient details 10%; procedure details 30%; and patient sign-off 27%. Laparoscopic cholecystectomy was the most common procedure (7/99) but there was significant variability in the documentation of complications: 12 in total, a median of 6 and a range of 2-9. In phase two, 44% (27/61) of hand-written forms were missing essential complications. There were no domain failures amongst 29 electronically-produced consent forms and no variability in the documentation of potential complications. CONCLUSION: Completion of hand-written consent forms suffers from wide variation and is frequently suboptimal. Electronically-produced, procedure-specific consent forms can improve the quality and consistency of consent documentation.

BACKGROUND: Simulation enables safe practice and facilitates objective assessment of technical skills. However, simulation training in breast surgery is rare and assessment remains subjective. The primary aim was to evaluate the construct validity of technical skills assessments in wide local excision (WLE). METHODS: Surgeons of different grades performed a WLE of a 25-mm palpable tumour on an in-house synthetic breast simulator. Procedures were videotaped (blinded), reviewed retrospectively, and independently rated against a procedure-specific global rating scale by two consultant breast surgeons. Specimen radiographs were obtained and the macroscopic distance from the 'tumour' edge to the resection margin was recorded in four cardinal directions. Expert consensus was used to construct an Oncoplastic Deviation Score (ODS), assigning points for excessively wide (more than 10 mm) and, conversely, close (less than 5 mm) macroscopic margins. RESULTS: Thirty-four surgeons (12 consultant surgeons, 12 specialty trainees and 10 core trainees) participated in the study. Video-based rating scores varied hierarchically with operator expertise (P < 0.050). Inter-rater reliability was excellent (α ≥ 0.80, P < 0.050 for all scales), and inter-rater agreement was moderate (κ = 0.132-0.361, P < 0.050 for all scales). Statistically significant differences were observed on pairwise comparisons between each grade of surgeon in scores for 'exposure', 'skin flap development', 'glandular remodelling', 'skin closure' and 'final product review' (P < 0.050). Consultants received significantly fewer ODS points than specialty trainees (P = 0.012) and core trainees (P = 0.028). Compared with experts (median 9.0 mm), wider margins were observed amongst specialty trainees (median 12.0 mm) and narrower margins amongst core trainees (median 7.1 mm) (P = 0.001). CONCLUSION: Video ratings of performance and a proposed ODS differentiate surgeons based on technical skills in WLE and may be useful for objective assessment of breast surgery trainees.

BACKGROUND: Prophylactic mastectomy (PM) has become increasingly common but is not without complications especially if accompanied by reconstructive surgery. In patients with sporadic unilateral breast cancer, contralateral PM offers no survival advantage. Multidisciplinary team (MDT) communication and interaction may facilitate shared decision-making and curtail PM rates. The aim of this study was investigate the effect of a regional MDT meeting on PM decision-making. METHODS: We conducted an observational study involving retrospective review of prospectively recorded MDT meeting records for a 151 patient requests for PM from 2011 to 2014. Final MDT decisions were recorded as PM 'accepted', 'declined' or 'pending'. For MDT sanctioned requests, the factors justifying PM were recorded. Where PM was declined, justification for MDT refusal was sought and recorded. RESULTS: Approximately half of all requests for PM have been upheld (53.0%) and 1/3 of requests have been declined (32.5%). Of those declined, low risk of contralateral breast cancer versus relatively high risk of systemic relapse were commonly cited as justification for PM refusal (45.7%). A proportion of patients who initiated PM discussion subsequently changed their minds (19.6%), or failed to attend clinic appointments (6.5%). Some patients were deemed medically unfit for complex reconstructive surgery (13%), or were declined on the basis of an apparent cosmetic drive for surgery (6.5%), concerns regarding depression or anxiety (2.2%) and/or if family history could not be substantiated (6.5%). DISCUSSION: MDT meetings facilitate cross-specialty interrogation of requests for PM, minimise unnecessary surgery and restrict PM to those likely to derive maximum benefit.

AIM: A systematic review of the literature was undertaken to examine reported cases of stump appendicitis (SA) to determine the relationship between SA and the original operative strategy (open vs laparoscopic), and to evaluate the clinical features and diagnosis. METHOD: A Pub-med search was conducted to identify cases of appendicitis of a residual stump following appendicectomy. Two original cases of SA following laparoscopic appendicectomy treated in our own hospitals are also included in the analysis. Sixty cases of SA reported in the English medical literature were analysed. RESULTS: The interval from the original appendicectomy ranged from 4 days to 50 years. SA followed appendicectomy in 58% of open and 31.6% of laparoscopic procedures. SA was frequently misdiagnosed as constipation or gastroenteritis, with a significant delay to surgery. Computerized tomography diagnosed SA in 46.6% of cases. Perforation with gangrene of the stump occurred in 40%. CONCLUSION: Stump appendicitis is rare. It may complicate open or laparoscopic appendicectomy. A high level of suspicion should be maintained in any patient with right sided abdominal pain and a history of prior appendicectomy.

Functional near infrared spectroscopy (fNIRS) is a rapidly developing neuroimaging modality for exploring cortical brain behaviour. Despite recent advances, the quality of fNIRS experimentation may be compromised in several ways: firstly, by altering the optical properties of the tissues encountered in the path of light; secondly, through adulteration of the recovered biological signals (noise) and finally, by modulating neural activity. Currently, there is no systematic way to guide the researcher regarding these factors when planning fNIRS studies. Conclusions extracted from fNIRS data will only be robust if appropriate methodology and analysis in accordance with the research question under investigation are employed. In order to address these issues and facilitate the quality control process, a taxonomy of factors influencing fNIRS data have been established. For each factor, a detailed description is provided and previous solutions are reviewed. Finally, a series of evidence-based recommendations are made with the aim of improving consistency and quality of fNIRS research.

The aim of this study was to validate the use of three models of fracture fixation in the assessment of technical skills. We recruited 21 subjects (six experts, seven intermediates, and eight novices) to perform three procedures: application of a dynamic compression plate on a cadaver porcine model, insertion of an unreamed tibial intramedullary nail, and application of a forearm external fixator, both on synthetic bone models. The primary outcome measures were the Objective Structural Assessment of technical skills global rating scale on video recordings of the procedures which were scored by two independent expert observers, and the hand movements of the surgeons which were analysed using the Imperial College Surgical Assessment Device. The video scores were significantly different for the three groups in all three procedures (p < 0.05), with excellent inter-rater reliability (alpha = 0.88). The novice and intermediate groups specifically were significantly different in their performance with dynamic compression plate and intramedullary nails (p < 0.05). Movement analysis distinguished between the three groups in the dynamic compression plate model, but a ceiling effect was demonstrated in the intramedullary nail and external fixator procedures, where intermediates and experts performed to comparable standards (p > 0.6). A total of 85% (18 of 21) of the subjects found the dynamic compression model and 57% (12 of 21) found all the models acceptable tools of assessment. This study has validated a low-cost, high-fidelity porcine dynamic compression plate model using video rating scores for skills assessment and movement analysis. It has also demonstrated that Synbone models for the application of and intramedullary nail and an external fixator are less sensitive and should be improved for further assessment of surgical skills in trauma. The availability of valid objective tools of assessment of surgical skills allows further studies into improving methods of training.

OBJECTIVES: Post-operative haemorrhage is a recognised complication and independent predictor of outcome in complex vascular surgery. The off-license administration of activated Recombinant Factor VII (rFVIIa) to treat haemorrhage in other surgical settings has been investigated, but concerns over potential adverse events have limited its use in vascular surgery. This article reports rFVIIa's method of action and systematically reviews rFVIIa's role in complex vascular surgery. METHODS: A systematic literature search identified articles reporting on rFVIIa administration within vascular surgery patients. Patient-specific data regarding transfusion requirements was extracted and pooled statistical analysis performed. RESULTS: 15 articles reporting 43 patients were identified. RFVIIa has been administered in open and endovascular procedures and in both elective and emergency settings. Major aortic surgery accounted for 75% of cases. The range of rFVIIa administered as a cumulative dose was large, as was the variation in initial dose. Transfusion data from 9 patients was pooled and analysed. Significant differences were found between pre- and post- rFVIIa for packed red cell transfusions (mean 29.2 vs. 8.2, p=0.015). Intra-arterial thrombosis was reported in 3 cases. CONCLUSIONS: RFVIIa may reduce haemorrhage in selected vascular surgical patients. Randomized controlled trials are justified to definitively investigate its role within this setting.

The effect of pre-infiltration local cooling of the site of inguinal herniorrhaphy on pain perception during infiltration of local anaesthetic was studied in a prospective randomised controlled trial. One hundred patients were randomly allocated to receive topical application of either a cooled saline bag (study group) or a saline bag at room temperature (control group) prior to injection of local anaesthetic. Pain scores were recorded using a visual analogue scale following application of the saline bags and again on completion of infiltration with local anaesthetic. There was no significant difference in pain scores following topical saline bag application. However, a highly significant difference (p = 0.0001, Mann-Whitney U) was observed between post-infiltration pain scores of the study group (median = 2) and the control group (median = 6).

BACKGROUND: Patients with sickle cell disease (SCD) are at increased risk for cholelithiasis. Laparoscopic cholecystectomy is the most frequent general surgical operation performed for this group of patients. Acute chest syndrome (ACS) is the most common cause of postoperative death among SCD patients. This study aimed to evaluate the impact of a novel perioperative management regimen involving prophylactic continuous positive airways pressure (CPAP) ventilation and avoidance of preoperative blood transfusion on postoperative SCD-related complications after laparoscopic cholecystectomy. METHODS: A retrospective study included all SCD patients who underwent laparoscopic cholecystectomy since 1997 at our institution. Medical notes were analyzed to assess the rates of postoperative complications in relation to the severity of SCD. RESULTS: A total of 13 patients were identified. There were no recorded episodes of acute painful crises and only one patient experienced an episode of ACS requiring protracted CPAP. CONCLUSION: Laparoscopic cholecystectomy can be safely performed for SCD patients without prior blood transfusion. A defined perioperative regimen including the use of routine postoperative prophylactic CPAP for these patients helps to reduce SCD-related postoperative complications such as ACS and painful vaso-occlusive crises.

INTRODUCTION: To compare the variations in consenting practice amongst trainees and consultant surgeons for laparoscopic cholecystectomy with specific reference to the documentation of significant risks of surgery. PATIENTS AND METHODS: A proforma was devised which included significant and/or commonly recognised complications of laparoscopic cholecystectomy. This was then cross-referenced with the consent forms for the 80 patients included in the study and the documented risks explained in each case were noted. RESULTS: The results showed that there is considerable variation between the three grades of clinicians involved in obtaining a patient's consent for laparoscopic cholecystectomy. There was a clear difference in emphasis of the significant complications depending on the seniority of the consenter. Over 80% of the consents in this study were still being obtained by junior staff. CONCLUSIONS: More often than not, patients are not provided with consistent information to make an informed choice. We suggest that a preprinted consent form will provide a more uniform approach to consenting practice for laparoscopic cholecystectomy.

Since 1980, we have surveyed at 4-yr intervals the metropolitan health departments initially reporting > 250 cases of tuberculosis to determine the perceived standard of practice for tuberculosis control and the factors affecting formulation of treatment policies. Between 1992 and 1996, use of supervised short-course (6 to 9 mo) intermittent therapy with multiple drugs including isoniazid, ethambutol, pyrazinamide, and rifampin increased from 4.3% to 46% of all new patients. Pyrazinamide use for initial treatment for children has increased substantially and now predominates (74.2% of patients in 1996 versus 48.1% of patients in 1992). Duration of treatment, which was 20 +/- 2.1 mo in 1980, is now 8.00 +/- 2.29 mo in 1996. The incidence of human immunodeficiency virus-associated tuberculosis, which was virtually unrecognized in 1984, has remained the same between 1992 and 1996 (18.0%). As in previous years, there was a wide variance among health departments in the incidence (< 5% to > 40%) of HIV-associated tuberculosis. After years of funding decreases, there has been an impressive increase in resources in the past 4 yr. In 1988, mean budget allocation for health departments decreased by 7.9% versus the prior 4 yr and, in 1992, there was no overall change in budget allocation after inflation versus 1988. In 1996, however, funds for treatment increased by 84 +/- 33%. This increase in funding has been translated into the greatly expanded use of supervised intermittent therapy and aggressive screening programs, which likely have resulted in the decreased incidence of tuberculosis since the prior survey.

Since 1978, we have surveyed the 28 metropolitan health departments initially reporting > 250 cases of tuberculosis/yr to determine the standard of practice in the control of pulmonary tuberculosis and the factors affecting treatment policy. In this survey, results were compared with data obtained in 1978, 1980, 1984, and 1988. As in the previous years, all departments completed the survey. The predominant treatment regimen was 6 months of chemotherapy (64 +/- 1.33% of patients) involving isoniazid (I), rifampin (R), and pyrazinamide (Z). Estimated duration of treatment, which had decreased from 20.2 +/- 2.1 months in 1980 to 7.58 +/- 1.02 months in 1988, increased to 9.34 +/- 2.32 months in 1992 (p < 0.01). This was attributed to an increase in drug-resistant cases (17 of 25 programs) and to increased incidence of HIV infection during the previous 4 yr. In 1984, HIV infection was estimated to coincide with tuberculosis in 2.54% of all patients, 7.72% in 1988, and 17.42% in 1992. Several other major departures from prior perceived practices were reported. In 1980, 32.1% of all patients were hospitalized initially for tuberculosis treatment, and this number decreased progressively to 17.8% in 1988; in 1992, 34.2 +/- 1.32% of patients with tuberculosis were hospitalized for initial treatment. In 1988, no program reported regular use of alternative therapy to isoniazid for chemoprophylaxis; in 1992, 21 programs used alternative regimens (predominantly R-containing). In 1992, nine programs reported increased funds for treatment of tuberculosis (27.2 +/- 1.97% after inflation), whereas 16 reported a mean decrease of 14% after inflation.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-eight metropolitan health departments reporting greater than 250 cases annually in 1978 were surveyed to determine the standard of practice in the control of pulmonary tuberculosis and the factors affecting treatment policy. The results were compared to previous surveys in 1978, 1980, and 1984 to determine the impact of policies recommended by the Centers for Disease Control, state health departments, and other agencies. A high degree of uniformity again was demonstrated in chemoprophylaxis and hospitalization policies. However, screening, drug toxicity monitoring, and post-treatment follow-up varied widely among programs. A major trend toward short-course chemotherapy (mean duration of treatment, 20.8 +/- 2.34 months in 1980 versus 7.59 +/- 1.02 months in 1988) accompanied inclusion of pyrazinamide in first-line treatment of 59.4% of all patients in 1988 versus none in 1980. The prevalence of acquired immune deficiency syndrome (AIDS) in association with tuberculosis was estimated to be 7.72% in 1988 versus 2.52% in 1984; nine programs identified AIDS + tuberculosis in greater than 5% of all new cases in 1988 versus only two programs in 1984. Health departments identified the recommendations of the Centers for Disease Control and their respective state health departments as the major source of treatment policy; recommendations of the World Health Organization, American Academy of Pediatrics, and peer-reviewed literature had little effect upon treatment policies. This survey identifies substantial departures from prior treatment policies, some of which are attributed to reduction in available funding, development of shorter-course technology, and recognition of new groups of patients at risk to develop tuberculosis in the major cities in the major cities in the United States.(ABSTRACT TRUNCATED AT 250 WORDS)
