Perceived impact of equality and equity in medical education by junior doctors in the UK.

This exploratory study was undertaken to provide an insight into issues of equality and equity that UK junior doctors perceive in relation to being able to achieve a work-life balance within educational and clinical practice. A survey with 443 junior doctors was conducted between May 2018 and September 2019. Thematic analysis of open question responses alongside correlative analyses were used to highlight issues in equity and equality faced by junior doctors. The survey revealed 77% were junior doctors in Health Education England (HEE) posts. 59% were noti n personal relationships, 60% had no children, 38% perceived the national recruitment process as helpful and 70% perceived HEE did not impact on their training. 72% had no personal barriers and 77% felt the role eas not a barrier. 1% identified no barriers. The research raised important implications for redress of equality and equity issues for all within inclusive postgraduate training in the UK.

Hip surgery and radiology reporting for children with cerebral palsy prior to initiation of a hip surveillance program.

PURPOSE: Hip displacement impacts quality of life for many children with cerebral palsy (CP). While early detection can help avoid dislocation and late-stage surgery, formalized surveillance programs are not ubiquitous. This study aimed to examine: 1) surgical practices around pediatric hip displacement for children with CP in a region without formalized hip surveillance; and 2) utility of MP compared to traditional radiology reporting for quantifying displacement. METHODS: A retrospective chart review examined hip displacement surgeries performed on children with CP between 2007-2016. Surgeries were classified as preventative, reconstructive, or salvage. Pre- and post-operative migration percentage (MP) was calculated for available radiographs using a mobile application and compared using Wilcoxon Signed Ranks test. MPs were also compared with descriptions in the corresponding radiology reports using directed and conventional content analyses. RESULTS: Data from 67 children (115 surgical hips) were included. Primary surgery types included preventative (63.5% hips), reconstructive (36.5%), or salvage (0%). For the 92 hips with both radiology reports and radiographs available, reports contained a range of descriptors that inconsistently reflected the retrospectively-calculated MPs. CONCLUSION: Current radiology reporting practices do not appear to effectively describe hip displacement for children with CP. Therefore, standardized reporting of MP is recommended.

Assessing the use of magnetic resonance imaging virtopsy as an alternative to autopsy: a systematic review and meta-analysis.

BACKGROUND: The post mortem examination or autopsy is a trusted method of identifying the cause of death. Patients and their families may oppose an autopsy for a variety of reasons, including fear of mutilation or owing to religious and personal beliefs. Imaging alternatives to autopsy have been explored, which may provide a viable alternative. OBJECTIVE: To explore the possibility of using MRI virtopsy to establish the cause of death as an alternative to the traditional post mortem examination or autopsy. METHODS: Systematic review was carried out of all studies, without language restriction, identified from Medline, Cochrane (1960-2016) and Embase (1991-2016) up to December 2016. Further searches were performed using the bibliographies of articles and abstracts. All studies reporting the diagnosis of the cause of death by both MRI virtopsy and traditional autopsy were included. RESULTS: Five studies with 107 patients, contributed to a summative quantitative outcome in adults. The combined sensitivity of MRI virtopsy was 0.82 (95% CI 0.56 to 0.94) with a diagnostic odds ratio (DOR) of 11.1 (95% CI 2.2 to 57.0). There was no significant heterogeneity between studies (Q=1.96, df=4, p=0.75, I2=0). Eight studies, with 953 patients contributed to a summative quantitative outcome in children. The combined sensitivity of MRI virtopsy was 0.73 (95% CI 0.59 to 0.84) with a DOR of 6.44 (95% CI 1.36 to 30.51). There was significant heterogeneity between studies (Q=34.95, df=7, p<0.01, I2=80). CONCLUSION: MRI virtopsy may offer a viable alternative to traditional autopsy. By using MRI virtopsy, a potential cost reduction of at least 33% is feasible, and therefore ought to be considered in eligible patients.

A meta-analysis comparing the risk of metastases in patients with rectal cancer and MRI-detected extramural vascular invasion (mrEMVI) vs mrEMVI-negative cases.

BACKGROUND: Pathological extramural vascular invasion (EMVI) is an independent prognostic factor in rectal cancer, but can also be identified on MRI-detected extramural vascular invasion (mrEMVI). We perform a meta-analysis to determine the risk of metastatic disease at presentation and after surgery in mrEMVI-positive patients compared with negative tumours. METHODS: Electronic databases were searched from January 1980 to March 2016. Conventional meta-analytical techniques were used to provide a summative outcome. Quality assessment of the studies was performed. RESULTS: Six articles reported on mrEMVI in 1262 patients. There were 403 patients in the mrEMVI-positive group and 859 patients in the mrEMVI-negative group. The combined prevalence of mrEMVI-positive tumours was 0.346(range=0.198-0.574). Patients with mrEMVI-positive tumours presented more frequently with metastases compared to mrEMVI-negative tumours (fixed effects model: odds ratio (OR)=5.68, 95% confidence interval (CI) (3.75, 8.61), z=8.21, df=2, P<0.001). Patients who were mrEMVI-positive developed metastases more frequently during follow-up (random effects model: OR=3.91, 95% CI (2.61, 5.86), z=6.63, df=5, P<0.001). CONCLUSIONS: MRI-detected extramural vascular invasion is prevalent in one-third of patients with rectal cancer. MRI-detected extramural vascular invasion is a poor prognostic factor as evidenced by the five-fold increased rate of synchronous metastases, and almost four-fold ongoing risk of developing metastases in follow-up after surgery.

Defining response to radiotherapy in rectal cancer using magnetic resonance imaging and histopathological scales.

AIM: To define good and poor regression using pathology and magnetic resonance imaging (MRI) regression scales after neo-adjuvant chemotherapy for rectal cancer. METHODS: A systematic review was performed on all studies up to December 2015, without language restriction, that were identified from MEDLINE, Cochrane Controlled Trials Register (1960-2015), and EMBASE (1991-2015). Searches were performed of article bibliographies and conference abstracts. MeSH and text words used included "tumour regression", "mrTRG", "poor response" and "colorectal cancers". Clinical studies using either MRI or histopathological tumour regression grade (TRG) scales to define good and poor responders were included in relation to outcomes [local recurrence (LR), distant recurrence (DR), disease-free survival (DFS), and overall survival (OS)]. There was no age restriction or stage of cancer restriction for patient inclusion. Data were extracted by two authors working independently and using pre-defined outcome measures. RESULTS: Quantitative data (prevalence) were extracted and analysed according to meta-analytical techniques using comprehensive meta-analysis. Qualitative data (LR, DR, DFS and OS) were presented as ranges. The overall proportion of poor responders after neo-adjuvant chemo-radiotherapy (CRT) was 37.7% (95%CI: 30.1-45.8). There were 19 different reported histopathological scales and one MRI regression scale (mrTRG). Clinical studies used nine and six histopathological scales for poor and good responders, respectively. All studies using MRI to define good and poor response used one scale. The most common histopathological definition for good response was the Mandard grades 1 and 2 or Dworak grades 3 and 4; Mandard 3, 4 and 5 and Dworak 0, 1 and 2 were used for poor response. For histopathological grades, the 5-year outcomes for poor responders were LR 3.4%-4.3%, DR 14.3%-20.3%, DFS 61.7%-68.1% and OS 60.7-69.1. Good pathological response 5-year outcomes were LR 0%-1.8%, DR 0%-11.6%, DFS 78.4%-86.7%, and OS 77.4%-88.2%. A poor response on MRI (mrTRG 4,5) resulted in 5-year LR 4%-29%, DR 9%, DFS 31%-59% and OS 27%-68%. The 5-year outcomes with a good response on MRI (mrTRG 1,2 and 3) were LR 1%-14%, DR 3%, DFS 64%-83% and OS 72%-90%. CONCLUSION: For histopathology regression assessment, Mandard 1, 2/Dworak 3, 4 should be used for good response and Mandard 3, 4, 5/Dworak 0, 1, 2 for poor response. MRI indicates good and poor response by mrTRG1-3 and mrTRG4-5, respectively.

Magnetic Resonance Tumor Regression Grade and Residual Mucosal Abnormality as Predictors for Pathological Complete Response in Rectal Cancer Postneoadjuvant Chemoradiotherapy.

BACKGROUND: Pathological complete response after chemoradiotherapy for rectal cancer occurs in 10% to 30% of patients. The best method to identify such patients remains unclear. Clinical assessment of residual mucosal abnormality is considered the most accurate method. In our institution, magnetic resonance tumor regression grade is performed as routine to assess response. OBJECTIVE: The purpose of this study was to compare the sensitivity of magnetic tumor regression grade against residual mucosal abnormality in detecting patients with a pathological complete response. DESIGN: Magnetic tumor regression grade scores from reported posttreatment MRI scans were documented. Magnetic tumor regression grade 1 to 3 was defined as likely to predict complete or near complete response. Gross appearances of the mucosa were derived from histopathology reports and used as a surrogate for clinical assessment (previously validated). Final histopathological staging was used to determine response. SETTINGS: The study was conducted at Royal Marsden National Health Service Trust, United Kingdom. PATIENTS: A total of 143 patients with rectal adenocarcinoma, diagnosed between September 1, 2009, and September 1, 2013, who received neoadjuvant chemoradiotherapy before curative surgery were included. MAIN OUTCOME MEASURES: The sensitivity of magnetic tumor regression grade and residual mucosal abnormality in detecting patients with pathological complete response were measured RESULTS: : Eighteen patients had a pathological complete response. Seventeen were detected using magnetic resonance tumor regression grade 1 to 3, with sensitivity 94% (95% CI, 0.74-0.99), and 10 were detected using residual mucosal abnormality, with sensitivity 62% (95% CI, 0.38-0.81). There was no statistical difference between the false positive rates for either method. Magnetic tumor regression grade identified 10 times more patients with a pathological complete response (diagnostic OR = 10.2 (95% CI, 1.30-73.73)) compared with clinical assessment with RMA. LIMITATIONS: Residual mucosal abnormality was used as a surrogate marker for endoscopic appearances. CONCLUSIONS: Most patients with rectal cancer who have a pathological complete response do not manifest a complete response at the mucosal level. Magnetic tumor regression grade is able to identify 10 times more patients than clinical assessment, with no significant compromise in the false positive rate.

FDG PET/CT Can Assess the Response of Locally Advanced Rectal Cancer to Neoadjuvant Chemoradiotherapy: Evidence From Meta-analysis and Systematic Review.

INTRODUCTION: Neoadjuvant chemoradiotherapy (CRT) is indicated in locally advanced rectal adenocarcinoma where there is a high risk of local recurrence based on preoperative imaging. Optimal radiological assessment of CRT response is unknown, and metabolic assessment of the tumor has been suggested to gauge response before surgical resection. PATIENTS AND METHODS: A systematic search of the MEDLINE database was performed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement to identify papers comparing pre- and post-CRT PET/CT in patients with locally advanced rectal adenocarcinoma with histopathological assessment of tumor regression. Papers were assessed with the QUADAS (Quality Assessment of Diagnostic Accuracy Studies) tool. Meta-analysis was performed for response index (RI) and SUVmax post-CRT. RESULTS: Ten of 69 studies met inclusion criteria containing a total of 538 patients. Methodological quality was high with low heterogeneity. In all studies, post-CRT PET/CT showed a reduction in SUVmax and the RI irrespective of histological findings. Tumors confirmed to have regressed after CRT had a mean difference of 12.21% higher RI (95% confidence interval, 6.51-17.91; P < 0.00001) compared with nonresponders. Mean difference between pre- and post-CRT SUVmax groups was -2.48 (95% confidence interval, -3.06 to -1.89; P < 0.00001) with histopathological responders having a lower post-CRT SUVmax. CONCLUSIONS: The available evidence suggests that PET/CT may be a useful addition to the current imaging modalities in the assessment of treatment response.

Systematic review of prognostic importance of extramural venous invasion in rectal cancer.

AIM: To systematically review the survival outcomes relating to extramural venous invasion in rectal cancer. METHODS: A systematic review was conducted using PRISMA guidelines. An electronic search was carried out using MEDLINE, EMBASE, CINAHL, Cochrane library databases, Google scholar and PubMed until October 2014. Search terms were used in combination to yield articles on extramural venous invasion in rectal cancer. Outcome measures included prevalence and 5-year survival rates. These were graphically displayed using Forest plots. Statistical analysis of the data was carried out. RESULTS: Fourteen studies reported the prevalence of extramural venous invasion (EMVI) positive patients. Prevalence ranged from 9%-61%. The pooled prevalence of EMVI positivity was 26% [Random effects: Event rate 0.26 (0.18, 0.36)]. Most studies showed that EMVI related to worse oncological outcomes. The pooled overall survival was 39.5% [Random effects: Event rate 0.395 (0.29, 0.51)]. CONCLUSION: Historically, there has been huge variation in the prevalence of EMVI through inconsistent reporting. However the presence of EMVI clearly leads to worse survival outcomes. As detection rates become more consistent, EMVI may be considered as part of risk-stratification in rectal cancer. Standardised histopathological definitions and the use of magnetic resonance imaging to identify EMVI will improve detection rates in the future.

Obese patients have similar short-term outcomes to non-obese in laparoscopic colorectal surgery.

AIM: To determine whether obese patients undergoing laparoscopic surgery within an enhanced recovery program had worse short-term outcomes. METHODS: A prospective study of consecutive patients undergoing laparoscopic colorectal resection was carried out between 2008 and 2011 in a single institution. Patients were divided in groups based on body mass index (BMI). Short-term outcomes including operative data, length of stay, complications and readmission rates were recorded and compared between the groups. Continuous data were analysed using t-test or one-way Analysis of Variance. χ(2) test was used to compare categorical data. RESULTS: Two hundred and fifty four patients were included over the study period. The majority of individuals (41.7%) recruited were of a healthy weight (BMI < 25), whilst 50 patients were classified as obese (19.6%). Patients were matched in terms of the presence of co-morbidities and previous abdominal surgery. Obese patients were found to have a statistically significant difference in The American Society of Anesthesiologists grade. Length of surgery and intra-operative blood loss were no different according to BMI. CONCLUSION: Obesity (BMI > 25) does not lead to worse short-term outcomes in laparoscopic colorectal surgery and therefore such patients should not be precluded from laparoscopic surgery.

Systematic review of emergent laparoscopic colorectal surgery for benign and malignant disease.

Laparoscopic surgery has become well established in the management of both and malignant colorectal disease. The last decade has seen increasing numbers of surgeons trained to a high standard in minimally-invasive surgery. However there has not been the same enthusiasm for the use of laparoscopy in emergency colorectal surgery. There is a perception that emergent surgery is technically more difficult and may lead to worse outcomes. The present review aims to provide a comprehensive and critical appraisal of the available literature on the use of laparoscopic colorectal surgery (LCS) in the emergency setting. The literature is broadly divided by the underlying pathology; that is, inflammatory bowel disease, diverticulitis and malignant obstruction. There were no randomized trials and the majority of the studies were case-matched series or comparative studies. The overall trend was that LCS is associated with shorter hospital stay, par or fewer complications but an increased operating time.Emergency LCS can be safely undertaken for both benign and malignant disease providing there is appropriate patient selection, the surgeon is adequately experienced and there are sufficient resources to allow for a potentially more complex operation.

Randomised controlled trials in plastic surgery: a systematic review of reporting quality.

BACKGROUND: We recently conducted a systematic review of the methodological quality of randomised controlled trials (RCTs) in plastic surgery. In accordance with convention, we are here separately reporting a systematic review of the reporting quality of the same RCTs. METHODS: MEDLINE® and the Cochrane Database of Systematic Reviews were searched by an information specialist from 1 January 2009 to 30 June 2011 for the MESH heading 'Surgery, Plastic'. Limitations were entered for English language, human studies and randomised controlled trials. Manual searching for RCTs involving surgical techniques was performed within the results. Scoring of the eligible papers was performed against the 23-item CONSORT Statement checklist. Independent secondary scoring was then performed and discrepancies resolved through consensus. RESULTS: Fifty-seven papers met the inclusion criteria. The median CONSORT score was 11.5 out of 23 items (range 5.3-21.0). Items where compliance was poorest included intervention/comparator details (7 %), randomisation implementation (11 %) and blinding (26 %). Journal 2010 impact factor or number of authors did not significantly correlate with CONSORT score (Spearman rho = 0.25 and 0.12, respectively). Only 61 % declared conflicts of interest, 75 % permission from an ethics review committee, 47 % declared sources of funding and 16 % stated a trial registry number. There was no correlation between the volume of RCTs performed in a particular country and reporting quality. CONCLUSIONS: The reporting quality of RCTs in plastic surgery needs improvement. Better education, awareness amongst all stakeholders and hard-wiring compliance through electronic journal submission systems could be the way forward. We call for the international plastic surgical community to work together on these long-standing problems.

A meta-analysis of outcomes following use of somatostatin and its analogues for the management of enterocutaneous fistulas.

OBJECTIVE: Several randomized control trials (RCTs) have compared somatostatin and its analogues versus a control group in patients with enterocutaneous fistulas (ECF). This study meta-analyzes the literature and establishes whether it shows a beneficial effect on ECF closure. METHODS: We searched MEDLINE, EMBASE, CINAHL, Cochrane, and PubMed databases according to PRISMA guidelines. Seventy-nine articles were screened. Nine RCTs met the inclusion criteria. Statistical analyses were performed using Review Manager 5.1. RESULTS: Somatostatin analogues versus control. Number of fistula closed: A significant number of ECF closed in the somatostatin analogue group compared to control group, P = 0.002.Time to closure: ECF closed significantly faster with somatostatin analogues compared to controls, P < 0.0001.Mortality: No significant difference between somatostatin analogues and controls, P = 0.68.Somatostatin versus control. Number of fistula closed: A significant number of ECF closed with somatostatin as compared to control, P = 0.04.Time to closure: ECF closed significantly faster with somatostatin than controls, P < 0.00001.Mortality: No significant difference between somatostatin and controls, P = 0.63 CONCLUSIONS: Somatostatin and octreotide increase the likelihood of fistula closure. Both are beneficial in reducing the time to fistula closure. Neither has an effect on mortality. The risk ratio (RR) for somatostatin was higher than the RR for analogues. This may suggest that somatostatin could be better than analogues in relation to the number of fistulas closed and time to closure. Further studies are required to corroborate these apparent findings.

A diagnostic accuracy meta-analysis of endoanal ultrasound and MRI for perianal fistula assessment.

BACKGROUND: Imaging modalities such as endoanal ultrasound or MRI can be useful preoperative adjuncts before the appropriate surgical intervention for perianal fistulas. OBJECTIVES: We present a systematic review of published literature comparing endoanal ultrasound with MRI for the assessment of idiopathic and Crohn's perianal fistulas. DESIGN: A meta-analysis was performed to obtain pooled values for specificity and sensitivity. SETTINGS: Electronic databases were searched from January 1970 to October 2010 for published studies. PATIENTS AND INTERVENTIONS: Four studies were used in our analysis. There were 241 fistulas in the ultrasound group and 240 in the magnetic resonance group. RESULTS: The combined sensitivity and specificity of magnetic resonance for fistula detection were 0.87 (95% CI: 0.63-0.96) and 0.69 (95% CI: 0.51-0.82). There was a high degree of heterogeneity between studies reporting on MRI sensitivity (df = 3, I = 93%). This compares to a sensitivity and specificity for endoanal ultrasound of 0.87 (95% CI: 0.70-0.95) and 0.43 (95% CI: 0.21-0.69). There was a high degree of heterogeneity between studies reporting on endoanal ultrasound sensitivity (df = 3, I = 92%). CONCLUSIONS: From the available literature, the summarized performance characteristics for MRI and endoanal ultrasound demonstrate comparable sensitivities at detecting perianal fistulas, although the specificity for MRI was higher than that for endoanal ultrasound. Both specificity values are considered to be diagnostically poor, however. The high degree of data heterogeneity and the shortage of applicable studies precludes any firm conclusions being made for clinical practice. Future trials with improved study design (including prospective data collection and consideration of verification bias) may help to further clarify the role of MRI in the assessment and treatment response monitoring of perianal fistulas (particularly in patients with Crohn's disease).

Single layer versus double layer suture anastomosis of the gastrointestinal tract.

BACKGROUND: Gastrointestinal anastomosis (GIA) is an essential step to maintain the continuity of gastrointestinal tract following intestinal resection. GIA is still a source of significant controversy among surgeons due to the use of variety of approaches. Adequate apposition by single layer or double layer anastomosis may affect outcome after GIA OBJECTIVES: The objective of this review is to compare the effectiveness of single layer GIA (SGIA) versus double layer GIA (DGIA) being used in general surgery. The particular question we would attempt to answer will be; is single layer hand made GIA in surgical patients is as effective as double layer? SEARCH METHODS: The CCCG (Colorectal Cancer Cochrane Group) Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (Issue 1, 2011), MEDLINE (until April 2011) , EMBASE ( The Intelligent Gateway to Biomedical & Pharmacological Information until April 2011), LILACS (The Latin American and Caribbean Health Sciences Library until April 2011 ) and Science Citation Index Expanded (SCI-E until April 2011) using the medical subject headings (MeSH) terms were searched without date, language or age restrictions. SELECTION CRITERIA: Randomised, controlled trials comparing the effectiveness of SGIA versus DGIA DATA COLLECTION AND ANALYSIS: At least two review authors independently scrutinised search results, selected eligible studies and extracted data. MAIN RESULTS: Seven randomised, controlled trials encompassing 842 patients undergoing SGIA versus DGIA were retrieved from the electronic databases. There were 408 patients in the SGIA group and 432 patients in the DGIA group. All included studies were small, with sample sizes ranging from 60 to 172. There was no heterogeneity among the included trials. Therefore, in the fixed effects model, incidence of anastomotic dehiscence, peri-operative complications and mortality was statistically equivalent between two techniques of GIA. Average hospital stay following SGIA and DGIA was also comparable. However, SGIA was superior in terms of shorter operative time. Sensitivity analysis of relatively good quality and poor quality trials supported same conclusion. AUTHORS' CONCLUSIONS: SGIA can be performed quicker as compared to double layer GIA. SGIA is comparable to DGIA in terms of anastomotic leak, peri-operative complications, mortality and hospital stay. SGIA may routinely be used for GIA following bowel resection. However, since this conclusion is derived from smaller number of patients recruited in relatively moderate quality trials, further trials should be aimed to reduce the limitations of this review.

Long-term MRI-guided combined anti-TNF-α and thiopurine therapy for Crohn's perianal fistulas.

BACKGROUND: Anti-tumor necrosis factor (TNF) therapy heals many Crohn's disease (CD) anal fistulas clinically but the rate, extent, and durability of deep tissue healing and factors influencing long-term outcome are unknown. METHODS: Consecutive patients with CD-related perianal (anal, rectovaginal, anolabial) fistulas treated with infliximab or adalimumab were monitored prospectively both clinically and radiologically using magnetic resonance imaging (MRI). RESULTS: Forty-one consecutive patients with CD-related perianal fistulas were treated with infliximab (n = 32) or adalimumab (n = 9; following infliximab failure) in combination with a thiopurine (unless intolerant). Fifty-eight percent of all patients, comprising 66% and 43% of infliximab and adalimumab-treated patients, respectively, demonstrated remission or response at 3 years. Thirty-three percent of infliximab treated patients maintained clinical remission at 3 years. Radiological healing lagged behind clinical remission by a median of 12 months. The likelihood of clinical remission at any time was five times greater in patients who had early clinical response within 6 weeks than those without. A higher number of fistula tracts was associated with reduced clinical remission. All patients who achieved radiological healing maintained healing on infliximab treatment, while only 43% maintained healing after cessation of anti-TNF therapy. CONCLUSIONS: Combination anti-TNF and thiopurine therapy provides sustained benefit in patients with perianal CD fistula. Early clinical response is associated with subsequent clinical remission. Radiological healing is slower than clinical healing. Radiologically healed fistula tracts maintain healing on infliximab but can recur after cessation of therapy.

Dieulafoy lesion endoscopically rubber banded, with further severe haematemesis requiring emergency laparotomy - Case report.

Dieulafoy lesion is a rare cause of massive gastrointestinal haemorrhage that can be fatal. We report a case of a sixty-year-old lady who presented to the emergency department with haematemesis and melaena. During oesophagogastroduodenoscopy (OGD), an active bleeding vessel was seen on the lesser curvature of the stomach, near the gastro-oesophageal junction and a diagnosis of Dieulafoy's lesion made. The lesion was managed with the application of two rubber bands. Our patient re-presented to the emergency department ten days later with severe haematemesis requiring an emergency laparotomy.A search of the entire English literature using PubMed with the phrase 'Dieulafoy' has been performed. Papers were reviewed in relation to management of this lesion with rubber banding via endoscopy. The current available haemostatic methods are described.

[Not Available]. / A betegek kor és nem szerinti eloszlása a laparoscopos cholecystectomia szövodményei és a mutét utáni felépülés szempontjából.

OBJECTIVES: Database review to analyse age and sex differences in complication and conversion rates and influence on return to normal daily activities and work after laparoscopic cholecystectomy (LC). METHODS: 658 patients had a laparoscopic cholecystectomy for proven gallstones between 9/4/2001 and 15/2/2006 under the care of one surgeon (F. H.) at Benenden hospital, Kent, UK. RESULTS: We had a 65.5% response rate with 431 replies at a mean follow up of 22.4 months (2.3-52.8). There was a male to female ratio of 5:23 with a mean age of 54.2 years (22-83). Using linear regression we found no significant correlation with operative time and variables of age and sex (df = 2, 251, R (2) = 0.03, F = 0.574, p < 0.564). No significant correlation with number of complications and age or sex (df = 2, 334, R (2) = 0.004, F = 1.615, p < 0.200). Age (Exp(B) = 1.040, p < 0.51) and sex (Exp(B) = 0.863, p < 0.855) had no effect on conversion. No difference was found in relation to age and sex with return to normal daily activities (df = 2, 307, F = 0.904, p < 0.406). Age was a non-significant predictor of return to work (Beta = 0.040, p < 0.572) however men return to work significantly sooner (Beta = 0.191, p < 0.007). CONCLUSIONS: Operative time, number of complications, conversion to open and return to normal daily activities may not be affected by age or sex of patients. Hospital stay may be longer in older patients. Men appear to return to work sooner. Further analysis with validated questionnaires are required.

The role of physician reminders in faecal occult blood testing for colorectal cancer screening.

BACKGROUND: Colorectal cancer screening in the form of faecal occult blood (FOB) testing can significantly reduce the burden of this disease and has been used as early as the 1970s. Effective involvement of GPs along with reminding physicians prior to seeing a patient may improve uptake. OBJECTIVE: This article is a systematic review of published literature examining the uptake of FOB testing after physician reminders as part of the colorectal cancer screening process. METHODS: Electronic databases were searched from January 1975 to October 2010. All studies comparing physician reminders (Rem) with controls (NRem) were identified. A meta-analysis was performed to obtain a summary outcome. RESULTS: Five comparative studies involving 25 287 patients were analyzed. There were 12 641 patients were in the Rem and 12 646 in the NRem group. All five studies obtained a higher percentage uptake when physician reminders were given. However, in only two of the studies were the percentage uptake significantly higher. There was significant heterogeneity among trials (I2 = 95%). The combined increase in FOB test uptake was not statistically significant (random effects model: risk difference = 6.6%, 95% CI: -2-14.7%; z = 1.59, P = 0.112). CONCLUSION: Reminding physicians about those patients due for FOB testing may not improve the effectiveness of a colorectal cancer screening programme. Further studies are required and should focus on areas where there is a lower baseline uptake and areas with high levels of deprivation.

A meta-analysis on the clinical effectiveness of transversus abdominis plane block.

STUDY OBJECTIVE: To study the efficacy of the transversus abdominal plane (TAP) block. DESIGN: Meta-analysis. SETTING: District general hospital. PATIENTS: 86 patients in the TAP block group and 88 in the non-TAP block group. MEASUREMENTS: Statistical analyses were performed using Microsoft Excel 2007 for Windows XP. Hedges g statistic was used for the calculation of standardized mean differences (SMD). Binary data (nausea) were summarized as risk ratios (RR). MAIN RESULTS: Patients with TAP block required less morphine after 24 hours than those who did not have the block (random effects model: SMD -4.81, 95% CI [-7.45, -2.17], z = -3.57, P < 0.001). There was less time to first request of morphine in the non-TAP block group (random effects model: SMD 4.80, 95% CI [2.16, 7.43], z = 3.57, P < 0.001). Patients in the TAP block group had less pain up to 24 hours postoperatively. No statistical differences were found with respect to nausea. CONCLUSIONS: TAP block reduces the need for postoperative opioid use, it increases the time first request for further analgesia, it provides more effective pain relief, and it reduces opioid-associated side effects.
