RESUMEN
BACKGROUND: The increase in medical negligence claims against the National Health Service (NHS) over the past decade has had a detrimental impact on limited financial and human resources that could otherwise be available for direct clinical care. The aim of this study was to review litigation claims in breast surgery as part of the national Getting It Right First Time quality improvement initiative, with the aim of identifying opportunities to improve clinical practice and patient safety. METHODS: All general and plastic surgical claims notified to NHS Resolution between April 2012 and April 2018 were reviewed. Claims related specifically to breast surgery were retrieved manually, and case summaries were analysed independently by two breast surgeons. RESULTS: From 6915 claims, 449 relating to breast surgery were identified and reviewed. The mean(s.d.) claimant age was 46(13) years. The median number of claims over the 6-year period per NHS trust was 2 (range 0-22). The most frequent causes of litigation were dissatisfaction with cosmetic outcome (121 claims, 26.9 per cent) and patient-reported delays in diagnosis (121, 26.9 per cent). A large proportion of claims related to breast implant surgery (78, 17.4 per cent), and issues regarding consent/communication were common (69, 15.4 per cent). The estimated annual cost of breast surgery litigation claims ranged from £5.57 to £9.59 million (6.35-11.02 million). CONCLUSION: Patient-reported delays in diagnosis and dissatisfaction with cosmetic outcome are the most common causes of litigation related to breast surgery. These key themes should be the focus for workforce learning, with the aim of improving patient care and experience.

BACKGROUND: The side-effects of Nissen fundoplication have led to modifications, including partial fundoplications such as an anterior 90° wrap. Five-year follow-up of two randomized trials suggested fewer side-effects following anterior 90° partial fundoplication, but better reflux control after Nissen fundoplication. However, longer-term outcomes have not been reported. This study combined data from previous trials to determine 10-year outcomes. METHODS: From 1999 to 2003, 191 patients were enrolled in two randomized trials comparing anterior 90° partial versus Nissen fundoplication. Trial protocols were similar, and data were combined to determine long-term clinical outcomes. Patients completed annual questionnaires assessing dysphagia, heartburn, medications, satisfaction and other symptoms. Visual analogue scales (0-10), a composite dysphagia score (0-45) and yes/no responses were used. RESULTS: Of the 191 patients, 152 (79·6 per cent) were available for 10-year follow-up. After anterior 90° fundoplication, patients reported less dysphagia to solids (score 2·03 versus 3·18 for the Nissen procedure; P = 0·037). Heartburn scores were lower after Nissen fundoplication (1·90 versus 2·83 for anterior 90° fundoplication; P = 0·035) and fewer patients required proton pump inhibitors (PPIs) (22 versus 39 per cent respectively; P = 0·035). Satisfaction scores were similar for both anterior 90° and Nissen groups (7·45 versus 7·36 respectively; P = 0·566), and the majority considered their original decision for surgery to be correct (86 versus 84 per cent; P = 0·818). CONCLUSION: After 10 years, both procedures achieved similar success as measured by global satisfaction measures. Patients who had a Nissen fundoplication reported more dysphagia, whereas more heartburn and PPI consumption were reported after anterior 90° fundoplication.

ANTECEDENTES: Para evitar los efectos secundarios de la fundoplicatura de Nissen se han propuesto modificaciones técnicas, incluyendo las fundoplicaturas parciales como la plicatura anterior de 90°. El seguimiento a 5 años de dos ensayos aleatorizados sugiere menos efectos secundarios tras la fundoplicatura anterior de 90°, pero mejor control del reflujo con la fundoplicatura de Nissen. Sin embargo, no se han descrito los resultados a largo plazo. Este estudio combinó datos de dos ensayos previos para determinar los resultados a 10 años. MÉTODOS: Entre 1999 y 2003, se reclutaron 191 pacientes en dos ensayos aleatorizados que comparaban la fundoplicatura parcial anterior 90° versus fundoplicatura de Nissen. Los protocolos de ambos ensayos fueron similares, y los datos se combinaron para determinar los resultados clínicos a largo plazo. Los pacientes completaron cuestionarios anuales que evaluaban disfagia, pirosis, medicaciones, satisfacción y otros síntomas. Se utilizaron escalas analógicas visuales (0-10), una variable compuesta para la puntuación de disfagia (0-45) y respuestas sí/no. RESULTADOS: De los 191 pacientes, 152 (79,6%) pudieron seguirse a los 10 años. Tras la fundoplicatura anterior de 90°, los pacientes refirieron menos disfagia a sólidos (2,03 versus 3,18, P = 0,037). Las puntuaciones de pirosis fueron inferiores tras fundoplicatura de Nissen (2,83 versus 1,90, P = 0,035) y menos pacientes tomaban inhibidores de la bomba de protones (proton pump inhibitors, PPIs; 22% versus 39%, P = 0,035). Las puntuaciones de satisfacción fueron similares para ambos grupos de fundoplicatura anterior 90° y Nissen (7,45 versus 7,36, P = 0,566), y la mayoría consideró su decisión original para la cirugía como correcta (86,1% versus. 83,8%, P = 0,818). Las tasas de reoperación fueron similares (10,0% versus 8,8%). CONCLUSIÓN: Después de 10 años, ambos procedimientos lograron un éxito similar medido con medidas de satisfacción global. Los pacientes con fundoplicatura de Nissen referían más disfagia mientras que los pacientes con fundoplicatura anterior 900 describieron más pirosis y consumo de PPIs.

At present there are two recognised guidelines for the echocardiographic assessment of left ventricular diastolic function provided by the British Society of Echocardiography and American Society of Echocardiography/European Association of Cardiovascular Imaging. However, no direct comparison of these guidelines has been performed to establish whether they provide similar diastolic grading. One hundred and eighty-nine consecutive patients in sinus rhythm who underwent transthoracic echocardiography for a primary indication of either heart failure assessment or assessment of left ventricular systolic function were extracted from our database (McKesson Cardiology). Left ventricular diastolic function assessment was performed using both guidelines and the results were compared. Chi-square, Kappa score and one-way ANOVA were used to evaluate the data at a level of P < 0.05. The most frequent outcome was unclassifiable diastolic function with significantly more patients being labelled unclassified with the British compared to American guidelines (47.4 vs 20.5%, P < 0.0001). Having excluded all unclassifiable patients, a significant difference still existed between the two guidelines with a higher proportion of grade one outcomes awarded by the ASE/EACVI guidelines. When grading subcategories were individually compared, there was significantly more grade one diastolic gradings awarded by American compared to the British guidelines (40.7 vs 20.1%, P < 0.0001). In 47% of patients it was not possible to grade diastolic function using the British guidelines, compared to 21% using the American guidelines. For those patients where grading was possible, there was a significant difference in patients classified with normal and grade one diastolic function when using British and American guidelines.
RESUMEN
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.

INTRODUCTION: The role of sentinel lymph node micrometastases on histopathological analysis is controversial in axillary staging and management in clinically node negative breast cancer. Long-term studies addressing the clinical relevance of occult breast cancer in sentinel lymph nodes based on molecular analysis are lacking. One Step Nucleic Acid Amplification (OSNA), a highly sensitive assay of cytokeratin 19 mRNA, is used intra-operatively for the detection of lymph node macro- and micrometastases in breast cancer. AIM: The aim of this study is to review the rate of micrometastases and further histopathological NSLN metastases, in our unit following the introduction of OSNA in Guildford. METHODS: Data was collected prospectively from the period of introduction 01/12/2008 to 31/05/2013. All patients eligible for sentinel lymph node biopsy were offered OSNA and operations were performed by the consultant breast surgeons. Presence or absence of micro-metastases depends on the agreed cut-off point on the amplification curve. On detection of micrometastases (+) and positive but inhibited (i+) metastases, a level 1 axillary clearance (ANC) was performed and for a macrometastasis (++), a level 3 ANC was carried out. RESULTS: 66% of the patients had negative SLN (n = 672) and 34% (n = 336) had positive sentinel lymph nodes who had further axillary surgery. Of these, 45% (n = 152/336) had macrometastases, 40% (n = 136/336) had micrometastases and 15% (48/336) had positive but inhibited results. There was no difference in the patient demographics and tumour characteristics in the various positive SLN groups. In patients with micrometastases, 15% (20/136) had further positive NLSNs and a further 6% (8/136) had >4 overall positive nodes (SLN + NSLN) thus requiring adjuvant supraclavicular/chest wall radiotherapy (p < 0.05). 25% of node positive patients had further NLSN metastases (85/336) and in these patients, the ratio of positive SLN/harvested SLN (+SLN/SLN) is constant at 1:1. This shows the likelihood of further positive NSLNs if all the harvested lymph nodes are positive. This linear trend is present in both micro-and macrometastases, thus correlating with the size and number of NSLN metastases. CONCLUSION: Our study reflects the tumour burden of NSLNs based on the molecular analysis of the SLN. OSNA has the potential to accurately identify axillary micrometastases. Micro-metastases are important as some of the patients with micrometastases had overall four positive nodes [SLN + NSLN] (criteria for radiotherapy in the absence of other adverse clinicopathological features). Also, our study highlights certain factors that predict the NSLN metastases, pending validation by further prospective long-term data. This will allow accurate calculation of the axillary tumour burden, particularly in patients with micro-metastases.

Search results for nucleon decays pâe^{+}X, pâµ^{+}X, nâνγ (where X is an invisible, massless particle) as well as dinucleon decays npâe^{+}ν, npâµ^{+}ν, and npâτ^{+}ν in the Super-Kamiokande experiment are presented. Using single-ring data from an exposure of 273.4 kton·yr, a search for these decays yields a result consistent with no signal. Accordingly, lower limits on the partial lifetimes of τ_{pâe^{+}X}>7.9×10^{32} yr, τ_{pâµ^{+}X}>4.1×10^{32} yr, τ_{nâνγ}>5.5×10^{32} yr, τ_{npâe^{+}ν}>2.6×10^{32} yr, τ_{npâµ^{+}ν}>2.2×10^{32} yr, and τ_{npâτ^{+}ν}>2.9×10^{31} yr at a 90% confidence level are obtained. Some of these searches are novel.
RESUMEN
Super-Kamiokande (SK) can search for weakly interacting massive particles (WIMPs) by detecting neutrinos produced from WIMP annihilations occurring inside the Sun. In this analysis, we include neutrino events with interaction vertices in the detector in addition to upward-going muons produced in the surrounding rock. Compared to the previous result, which used the upward-going muons only, the signal acceptances for light (few-GeV/c^{2}-200-GeV/c^{2}) WIMPs are significantly increased. We fit 3903 days of SK data to search for the contribution of neutrinos from WIMP annihilation in the Sun. We found no significant excess over expected atmospheric-neutrino background and the result is interpreted in terms of upper limits on WIMP-nucleon elastic scattering cross sections under different assumptions about the annihilation channel. We set the current best limits on the spin-dependent WIMP-proton cross section for WIMP masses below 200 GeV/c^{2} (at 10 GeV/c^{2}, 1.49×10^{-39} cm^{2} for χχâbb[over ¯] and 1.31×10^{-40} cm^{2} for χχâτ^{+}τ^{-} annihilation channels), also ruling out some fraction of WIMP candidates with spin-independent coupling in the few-GeV/c^{2} mass range.
RESUMEN
PURPOSE: Esophageal cancer has a high mortality rate, and its multimodality treatment is often associated with significant rates of severe toxicity. Effort is needed to uncover ways to maximize effectiveness of therapy through identification of predictive markers of response and toxicity. As such, the aim of this study was to identify genes predictive of chemoradiotherapy-induced gastrointestinal toxicity using an immune pathway-targeted approach. METHODS: Adults with esophageal cancer treated with chemotherapy consisting of 5-fluorouracil and cisplatin and 45-50 Gy radiation were recruited to the study. Pre-therapy-collected whole blood was analyzed for relative expression of immune genes using real-time polymerase chain reaction (RT-PCR). Gene expression was compared between patients who experienced severe regimen-related gastrointestinal toxicity vs. those experiencing mild to moderate toxicity. RESULTS: Blood from 31 patients were analyzed by RT-PCR. Out of 84 immune genes investigated, TNF was significantly elevated (2.05-fold, p = 0.025) in the toxic group (n = 12) compared to the non-toxic group (n = 19). Nausea and vomiting was the most commonly documented severe toxicity. No associations between toxicity and response, age, sex, histology, or treatment were evident. CONCLUSIONS: This study supports evidence of TNF as a predictive biomarker in regimen-related gastrointestinal toxicity. Confirming these findings in a larger cohort is warranted.

The trilepton nucleon decay modes pâe+νν and pâµ+νν violate |Δ(B-L)| by two units. Using data from a 273.4 kt yr exposure of Super-Kamiokande a search for these decays yields a fit consistent with no signal. Accordingly, lower limits on the partial lifetimes of τpâe+νν>1.7×10(32) years and τpâµ+νν>2.2×10(32) years at a 90% confidence level are obtained. These limits can constrain Grand Unified Theories which allow for such processes.
RESUMEN
We report an indication that the elastic scattering rate of solar B8 neutrinos with electrons in the Super-Kamiokande detector is larger when the neutrinos pass through Earth during nighttime. We determine the day-night asymmetry, defined as the difference of the average day rate and average night rate divided by the average of those two rates, to be [-3.2 ± 1.1(stat) ± 0.5(syst)]%, which deviates from zero by 2.7 σ. Since the elastic scattering process is mostly sensitive to electron-flavored solar neutrinos, a nonzero day-night asymmetry implies that the flavor oscillations of solar neutrinos are affected by the presence of matter within the neutrinos' flight path. Super-Kamiokande's day-night asymmetry is consistent with neutrino oscillations for 4 × 10(-5) eV(2) ≤ Δm 2(21) ≤ 7 × 10(-5) eV(2) and large mixing values of θ12, at the 68% C.L.
RESUMEN
INTRODUCTION: One-Step Nucleic acid Amplification (OSNA) is a molecular biological assay of cytokeratin-19 (a breast epithelial marker) mRNA. It can be employed intra-operatively for detection of lymph node metastases in breast carcinoma. Patients with positive sentinel nodes may proceed to axillary lymph node dissection (ALND) level I or higher dependent upon the OSNA quantitative result, during the same surgical procedure, avoiding a second operation and eliminating the technical difficulties possibly associated with delayed ALND. AIMS: Our Breast Unit was the first in the UK to implement this novel technique in routine practice. This study reviews our first 44-month data following introduction of OSNA "live" on whole sentinel nodes following an extensive validation study (Snook et al.).(9) METHODS: Data was collected prospectively from the period of introduction 01/12/2008 to 30/08/2012. All patients eligible for sentinel node biopsy were offered OSNA and operations were performed by five consultant breast surgeons. On detection of macro-metastasis a level II/III and for a micro-metastasis a level I ALND was performed. RESULTS: A total of 859 patients (1709 sentinel lymph nodes) were analysed. All except one were females. The majority underwent wide local excision (73.4%, n = 631) or mastectomy 25% (n = 215) and 1.6% (13) underwent SLN biopsy alone. IDC was seen in 79% (n = 680) of the patients and 53.5% (n = 460) had grade II tumours. One-third (30.8%, n = 265) had positive sentinel nodes and had further axillary surgery at the time of SLN biopsy. Of these, 47% (n = 125/265) had macro-metastases, 38% (n = 101/265) had micro-metastases and 14.7% (n = 39/265) had "positive but inhibited" results. Positive non-sentinel lymph nodes (NSLN) were seen in 35% (44/125) of those with macro-metastases; 17.8% (18/101) of the patients with micro-metastases and 10.2% (4/39) of the "positive but inhibited" group. CONCLUSION: In our series over a third of our patients had positive lymph nodes detected with OSNA allowing them to proceed directly to axillary surgery at the same operation. This technique eliminates the need for a second operation in sentinel lymph node positive patients and avoids the anxiety waiting for histological results.

INTRODUCTION: Malignant transformation of a phyllodes tumour is a rare form of breast cancer, accounting for just 0.5% of all breast cancer cases.(1) PRESENTATION OF CASE: We report a case of a 49 year old female with rapidly progressive, multifocal disease. She initially presented with two giant fibroadenomas which were excised. She represented eight months post surgery with two new lesions in the same breast, one suspicious, one suggestive of fibroadenoma. Biopsy was borderline. Surgery was therefore scheduled for wide local excision. At localisation two weeks later, at least eight lesions were seen on ultrasound scan. Three were removed as histology was at this point unknown to conserve the breast. Histology revealed intermediate grade DCIS, benign Phyllodes and borderline/malignant phyllodes. She was scheduled for mastectomy and immediate Strattice reconstruction. An MRI was performed pre-operatively to ascertain extent of disease. Two weeks post localisation, 13 lesions were identified. The right breast was entirely unaffected. Surgery interval was three weeks and final histology revealed 18 lesions, ranging from fibroadenoma through to borderline/malignant phyllodes with an incidental papilloma. DISCUSSION: This is the first report of such rapid progression of disease, with 16 new lesions, of varied histology, developing in just an eight week period. CONCLUSION: This case highlights the difficulty of forming a clear diagnostic and therapeutic pathway in this highly variable disease. Arguments for over and under treating these patients remain but those with any borderline/malignant potential have to be removed as recurrence is both common and aggressive, with a clear surgical margin the only proven protective factor.
RESUMEN
BACKGROUND: There are few reports of large patient cohorts with long-term follow-up after laparoscopic antireflux surgery. This study was undertaken to evaluate changes in surgical practice and outcomes for laparoscopic antireflux surgery over a 20-year period. METHODS: A standardized questionnaire, prospectively applied annually, was used to determine outcome for all patients undergoing laparoscopic fundoplication in two centres since commencing this procedure in 1991. Visual analogue scales ranging from 0 to 10 were used to assess symptoms of heartburn, dysphagia and satisfaction with overall outcome. Data were analysed to determine outcome across 20 years. RESULTS: From 1991 to 2010, 2261 consecutive patients underwent laparoscopic fundoplication at the authors' institutions. Follow-up ranged from 1 to 19 (mean 7.6) years. Conversion to open surgery occurred in 73 operations (3.2 per cent). Revisional surgery was performed in 216 patients (9.6 per cent), within 12 months of the original operation in 116. There was a shift from Nissen to partial fundoplication across 20 years, and a recent decline in operations for reflux, offset by an increase in surgery for large hiatus hernia. Dysphagia and satisfaction scores were stable, and heartburn scores rose slightly across 15 years of follow-up. Heartburn scores were slightly higher and reoperation for reflux was more common after anterior partial fundoplication (P = 0.005), whereas dysphagia scores were lower and reoperation for dysphagia was less common (P < 0.001). At 10 years, satisfaction with outcome was similar for all fundoplication types. CONCLUSION: Laparoscopic Nissen and partial fundoplications proved to be durable and achieved good long-term outcomes. At earlier follow-up, dysphagia was less common but reflux more common after anterior partial fundoplication, although differences had largely disappeared by 10 years.

BACKGROUND: Patients may be unwilling to participate in clinical trials if they perceive risks. Outcomes were evaluated following surgery for gastro-oesophageal reflux in patients recruited to randomized trials compared with patients not in trials. METHODS: This study compared outcomes of patients who had surgery for reflux within or outside randomized trials between 1994 and 2009. The choice of procedure outside each trial was according to surgeon or patient preference. Clinical outcomes were determined 1 and 5 years after surgery using a standardized questionnaire, with analogue scales to assess heartburn, dysphagia and overall satisfaction. Subgroup analysis was undertaken for those aged less than 75 years undergoing laparoscopic Nissen fundoplication. RESULTS: Some 417 patients entered six randomized trials evaluating surgery for reflux and 981 underwent surgery outside the trials. The trial group contained a higher proportion of men and younger patients, and patients in trials were more likely to have undergone Nissen fundoplication. At 1 year, patients in the trials had slightly lower heartburn scores and less abdominal bloating, but otherwise similar outcomes to those not in the trials. At 5 years there were no differences, except for a slightly higher dysphagia score for liquids in the trial group. For the subgroup analysis, demographic data were similar for both groups. There were no differences at 1 year, but at 5 years patients enrolled in the trials had higher scores for dysphagia for liquids and heartburn. All of the statistically significant differences were thought unlikely to be clinically relevant. CONCLUSION: Participation in a randomized trial assessing surgery for reflux did not influence outcomes.

BACKGROUND: The prognosis of patients with synchronous bilateral breast cancer (SBBC) is usually based on the tumour with the worst pathological features. There is little evidence in the literature for this assumption, potentially impairing reasoned decisions on optimal adjuvant therapy. METHODS: This was a case-control study in which 68 women with SBBC were matched with 128 women with unilateral breast cancer. Both the GuysRisk prognostic model and the Nottingham Prognostic Index were used to determine the bilateral tumour with the poorer prognosis. Controls were matched for age, menopausal status, date of diagnosis, histological type and grade, and oestrogen receptor and axillary node status. RESULTS: Both prognostic models indicated the same side tumour with the worst prognosis. Kaplan-Meier survival curves for both disease-free and overall survival showed no significant difference in outcome between the two groups. CONCLUSION: Prognosis was determined by the tumour with the worst prognosis, with no additional worsening of outcome incurred from the second tumour.

AIMS: The aims of this study were to evaluate the sensitivity, specificity; accuracy, usefulness and role of core biopsy imprint cytology (CBIC) in the one-stop breast clinic in a District General Hospital. METHODS: A retrospective study was made of symptomatic patients attending a district general hospital one-stop clinic over a five year period where a core biopsy had been performed and an imprint of the core had been made for cytological analysis. The performance of the technique was evaluated by comparing the results of CIBC with the definitive histological analysis of the core biopsy tissue. RESULTS: Over a five year period, imprints were made from 819 core biopsies. Adequate cellularity for cytological analysis was found in 94.8% (778/819) of the imprints. Out of the 778 lesions analysed, 432 were malignant (55.5%). The sensitivity, specificity, positive predictive value, negative predictive value and concordance were 97.7%, 94.2%, 93.1%, 98.1% and 95.5% respectively. CONCLUSION: Core Biopsy Imprint Cytology is a rapid, reliable and accurate technique which enhances the known benefits of automated core biopsy. It allows core biopsies to be used successfully in the 'one-stop' clinic setting and obviates the need to use Fine Needle Aspiration Cytology (FNAC). When CBIC is used, there is a reduction in diagnostic waiting time (over core biopsy on its own) and an increase in diagnostic performance (over FNAC). This translates to an improvement in the management of patients with breast cancer through the earlier availability of the diagnosis and fewer out-patient appointments.

OBJECTIVE: Rise in carcinoembryonic antigen (CEA) above normal limits can indicate recurrent colorectal cancer. The aim of this study was to evaluate whether a small rise in CEA, even within normal limits was a sensitive indicator of recurrence. METHOD: 150 patients aged 22-87 years were followed up for a mean of 27 months after colorectal surgery with CEA 3 and 6 monthly computerized tomography. We analysed whether a rise in CEA > 1 ng/ml correlated with recurrence of metastases. RESULTS: Forty-six of 139 patients in final analysis had recurrent disease. A rise in CEA > 1 had a predictive value of 74% for recurrence or metastases (sensitivity 80%, specificity 86%). These findings were similar whether or not the CEA was normal preoperatively. CONCLUSION: If CEA is measured after surgery for colorectal cancer, a rise of >1 in the patient's postoperative value is predictive for recurrence or metastases with an overall sensitivity of 80% and specificity of 86%. Previous studies have recognized the role of large rises in CEA in predicting recurrence but this study shows that small changes in CEA may be significant even if these levels would be traditionally within 'normal' limits.

OBJECTIVE: The majority of young adults referred with rectal bleeding to a colorectal specialist clinic have a very low risk of serious disease such as cancer, and a high chance of gaining symptom relief by simple dietary changes. To determine whether young low-risk patients with rectal bleeding can be managed with a structured telephonic interview and dietary advice, rather than an outpatient visit. METHOD: A single-blinded, prospective, randomized controlled trial was performed in two stages. Patients under 40 years with rectal bleeding only were offered inclusion. Part-I trial: Patients were interviewed on telephone by the colorectal nurse specialist (CNS) and randomized to receive dietary advice (Advice Group) or not (Control Group). All patients were seen in clinic 6 weeks later by a doctor 'blinded' to their trial status. Part-II trial: Patients were interviewed on telephone by the CNS and again randomized to an Advice Group or a Control Group. The Control Group were seen in clinic 6 weeks later. The Advice Group were telephoned again 6 weeks later, and if their bleeding had stopped, were not brought to clinic. All patients were tracked for a year after the study to ensure no adverse diagnoses came to light. RESULTS: Part-I trial: 63 of 89 eligible patients were contactable and none refused the study. Seventy per cent of the Advice Group compared with 33% (P = 0.001) of the Control Group had symptomatic improvement when seen in clinic. Approximately 30% of each group required further treatment. Part-II trial: 54 of 94 eligible patients were contactable. However a further nine declined to enter the trial; 90% of patients in the Advice Group had improved at 6 weeks as judged by telephone interview compared with 56% of patients in the Control Group (P = 0.024) who were seen in clinic. The 90% of patients who improved in the Advice Group did not need to come to clinic to be seen. In both parts of the trial, the CNS identified a small number of patients with urgent symptoms at interview and brought them to clinic. The majority had anal fissures or haemorrhoids although in Part-II, one patient had ulcerative colitis and one had colorectal cancer. CONCLUSION: Telephonic consultation is an effective way of identifying those patients with urgent symptoms among a cohort of young adults referred to the hospital with rectal bleeding. Telephonic dietary advice leads to resolution of rectal bleeding in the majority of patients without urgent symptoms.
