Abstract
BACKGROUND Aspirin and eicosapentaenoic acid (EPA) have colorectal polyp prevention activity, alone and in combination. This study measured levels of plasma and rectal mucosal oxylipins in participants of the seAFOod 2 × 2 factorial, randomised, placebo-controlled trial, who received aspirin 300 mg daily and EPA 2000 mg free fatty acid, alone and in combination, for 12 months. METHODS Resolvin (Rv) E1, 15-epi-lipoxin (LX) A4 and respective precursors 18-HEPE and 15-HETE (with chiral separation) were measured by ultra-high performance liquid chromatography-tandem mass spectrometry in plasma taken at baseline, 6 months and 12 months, as well as rectal mucosa obtained at trial exit colonoscopy at 12 months, in 401 trial participants. RESULTS Despite detection of S- and R- enantiomers of 18-HEPE and 15-HETE in ng/ml concentrations, RvE1 or 15‑epi-LXA4 were not detected above a limit of detection of 20 pg/ml in plasma or rectal mucosa, even in individuals randomised to both aspirin and EPA. We have confirmed in a large clinical trial cohort that prolonged (12 months) treatment with EPA is associated with increased plasma 18-HEPE concentrations (median [inter-quartile range] total 18-HEPE 0.51 [0.21-1.95] ng/ml at baseline versus 0.95 [0.46-4.06] ng/ml at 6 months [P<0.0001] in those randomised to EPA alone), which correlate strongly with respective rectal mucosal 18-HEPE levels (r = 0.82; P<0.001), but which do not predict polyp prevention efficacy by EPA or aspirin. CONCLUSION Analysis of seAFOod trial plasma and rectal mucosal samples has not provided evidence of synthesis of the EPA-derived specialised pro-resolving mediator RvE1 or aspirin-trigged lipoxin 15‑epi-LXA4. We cannot rule out degradation of individual oxylipins during sample collection and storage but readily measurable precursor oxylipins argues against widespread degradation.

Abstract
AIM The delivery of the Scottish Bowel Screening Programme (SBoSP) is rooted in the provision of a high quality, effective and participant-centred service. Safe and effective colonoscopy forms an integral part of the process. Additional accreditation as part of a multi-faceted programme for participating colonoscopists, as in England, does not exist in Scotland. This study aimed to describe the quality of colonoscopy in the SBoSP and compare this to the English national screening standards. METHODS Data were collected from the SBoSP between 2007 and 2014. End-points for analysis were caecal intubation, cancer, polyp and adenoma detection, and complications. Overall results were compared with 2012 published English national standards for screening and outcomes from 2006 to 2009. RESULTS During the study period 53 332 participants attended for colonoscopy. The colonoscopy completion rate was 95.6% overall. The mean cancer detection rate was 7.1%, the polyp detection rate was 45.7% and the adenoma detection rate was 35.5%. The overall complication rate was 0.47%. CONCLUSION Colonoscopy quality in the SBoSP has exceeded the standard set for screening colonoscopy in England, despite not adopting a multi-faceted programme for screening colonoscopy. However, the overall adenoma detection rate in Scotland was 9.1% lower than that in England which has implications for colonoscopy quality and may have an impact on cancer prevention rates, a key aim of the SBoSP.

Abstract
INTRODUCTION Colonoscopy is the gold standard test for investigating lower gastrointestinal symptoms and is an important therapeutic tool for colonic polypectomy. This paper is aimed at the general physician and examines the role of colonoscopy in very elderly patients by exploring the particular risks in this population, the yield of colonoscopy and potential alternative investigations. SOURCES OF DATA Original research and review articles were identified through selective PubMed searches. Guidelines were identified through interrogation of national and international society websites in addition to PubMed searches. AREAS OF AGREEMENT Advanced age alone is not a reason to avoid investigation. The decision to perform colonoscopy in this population must take into account indication and yield, risks of the procedure and bowel preparation, physical fitness of the patient, potential alternative and the ability to consent. As a general rule, the principle of 'first doing no harm' should be applied and requires balancing of the risks of the procedure and preparation with the benefits of doing the test. AREAS OF CONTROVERSY There is no defined upper age limit at which colonoscopy is contraindicated, however; the National Health Service Bowel Cancer Screening Programme stops inviting patients for screening and surveillance colonoscopy at age 75. GROWING POINTS AND AREAS TIMELY FOR DEVELOPING RESEARCH The concepts of 'first do no harm' and shared decision-making are not new but are increasingly important, particularly in this patient group. It is crucial to provide patients with information about risks, benefits and alternative investigations to empower their decision-making.

Abstract
OBJECTIVE The role of serrated polyps (SPs) as colorectal cancer precursor is increasingly recognised. However, the true prevalence SPs is largely unknown. We aimed to evaluate the detection rate of SPs subtypes as well as serrated polyposis syndrome (SPS) among European screening cohorts. METHODS Prospectively collected screening cohorts of ≥1000 individuals were eligible for inclusion. Colonoscopies performed before 2009 and/or in individuals aged below 50 were excluded. Rate of SPs was assessed, categorised for histology, location and size. Age-sex-standardised number needed to screen (NNS) to detect SPs were calculated. Rate of SPS was assessed in cohorts with known colonoscopy follow-up data. Clinically relevant SPs (regarded as a separate entity) were defined as SPs ≥10 mm and/or SPs >5 mm in the proximal colon. RESULTS Three faecal occult blood test (FOBT) screening cohorts and two primary colonoscopy screening cohorts (range 1.426-205.949 individuals) were included. Rate of SPs ranged between 15.1% and 27.2% (median 19.5%), of sessile serrated polyps between 2.2% and 4.8% (median 3.3%) and of clinically relevant SPs between 2.1% and 7.8% (median 4.6%). Rate of SPs was similar in FOBT-based cohorts as in colonoscopy screening cohorts. No apparent association between the rate of SP and gender or age was shown. Rate of SPS ranged from 0% to 0.5%, which increased to 0.4% to 0.8% after follow-up colonoscopy. CONCLUSIONS The detection rate of SPs is variable among screening cohorts, and standards for reporting, detection and histopathological assessment should be established. The median rate, as found in this study, may contribute to define uniform minimum standards for males and females between 50 and 75 years of age.

Abstract
OBJECTIVE Optimising uptake of colorectal cancer (CRC) screening is important to achieve projected health outcomes. Population-based screening by flexible sigmoidoscopy (FS) was introduced in England in 2013 (NHS Bowel scope screening). Little is known about reactions to the invitation to participate in FS screening, as offered within the context of the Bowel scope programme. We aimed to investigate responses to the screening invitation to inform understanding of decision-making, particularly in relation to non-participation in screening. DESIGN Qualitative analysis of semistructured in-depth interviews and written accounts. PARTICIPANTS AND SETTING People from 31 general practices in the North East and East of England invited to attend FS screening as part of NHS Bowel scope screening programme were sent invitations to take part in the study. We purposively sampled interviewees to ensure a range of accounts in terms of beliefs, screening attendance, sex and geographical location. RESULTS 20 screeners and 25 non-screeners were interviewed. Written responses describing reasons for, and circumstances surrounding, non-participation from a further 28 non-screeners were included in the analysis. Thematic analysis identified a range of reactions to the screening invitation, decision-making processes and barriers to participation. These include a perceived or actual lack of need; inability to attend; anxiety and fear about bowel preparation, procedures or hospital; inability or reluctance to self-administer an enema; beliefs about low susceptibility to bowel cancer or treatment and understanding of harm and benefits. The strength, rather than presence, of concerns about the test and perceived need for reassurance were important in the decision to participate for screeners and non-screeners. Decision-making occurs within the context of previous experiences and day-to-day life. CONCLUSIONS Understanding the reasons for non-participation in FS screening can help inform strategies to improve uptake and may be transferable to other screening programmes.

Abstract
BACKGROUND: Laryngeal electromyography (LEMG) is a valuable diagnostic/prognostic test for patients with suspected laryngeal neuromuscular disorders. OBJECTIVE: To report our experience with diagnostic LEMG at the Center for voice Disorders of Wake Forest University and to evaluate the impact of LEMG on clinical management. METHODS: Retrospective chart review of 415 patients who underwent diagnostic LEMG over a 5-year period (1995–1999). RESULTS: Of 415 studies, 83% (346 of 415) were abnormal, indicating a neuropathic process. LEMG results altered the diagnostic evaluation (eg, the type of radiographic imaging) in 11% (46 of 415) of the patients. Unexpected LEMG findings (eg, contralateral neuropathy) were found in 26% (107 of 415) of the patients, and LEMG results differentiated vocal fold paralysis from fixation in 12% (49 of 415). Finally, LEMG results altered the clinical management (eg, changed the timing and/or type of surgical procedure) in 40% (166 of 415) of the patients. CONCLUSIONS: LEMG is a valuable diagnostic test that aids the clinician in the diagnosis and management of laryngeal neuromuscular disorders.

Abstract
Understanding and addressing patient attitudes to their care facilitates their engagement and attendance, improves the quality of their experience and the appropriate utilisation of resources. Gastrointestinal endoscopy is a commonly performed medical procedure that can be associated with patient anxiety and apprehension. Measuring patient attitudes to endoscopy can be undertaken through a number of approaches with contrasting benefits and limitations. Methodological validation is necessary for accurate interpretation of results and avoiding bias. Retrospective post-procedure questionnaires measuring satisfaction are easily undertaken but have limited value, particularly in directing service improvements. Patient experience questionnaires indicate areas of poor care but may reflect the clinician's not the patient's perspective. Directly assessing patient priorities and expectations identifies what is important to patients in their healthcare experience (patient-reported value) that can also provide a basis for other forms of evaluation. Published studies of patient attitudes to their endoscopy procedure indicate the importance of ensuring that endoscopists and their staff control patient discomfort, have adequate technical skill and effectively communicate with their patient relating to the procedure and results. Environmental factors, including noise, privacy and the single-sex environment, are considered to have less value. There are contrasting views on patient attitudes to waiting times for the procedure. Implementing patient-centred care in endoscopy requires an understanding of what patients want from their healthcare experience. The results from available studies suggest implications for current practice that relate to the training and practice of the endoscopist and their staff.

Abstract
Objectives: Fiberoptic endoscopic evaluation of swallowing with sensory testing has been used to assess the integrity of laryngopharyngeal sensory and motor components. The pharyngeal squeeze is a maneuver used during fiberoptic endoscopic evaluation of swallowing with sensory testing to assess pharyngeal motor function. Although the pharyngeal squeeze manuever has been used in numerous scientific publications, its reliability has not been critically evaluated. Therefore, we sought to evaluate the reliability of the pharyngeal squeeze maneuver. Methods: Forty individuals who were undergoing fiberoptic laryngoscopy for various reasons were instructed to perform the pharyngeal squeeze maneuver. Three different clinicians reviewed the videotape on 4 separate occasions. The clinicians were first asked to rate each side of the pharynx as normal, diminished, or absent. They were then instructed to simply rate the maneuver as normal or abnormal. The interobserver and intraobserver reliability of the pharyngeal squeeze maneuver were assessed with the kappa coefficient. Results: The mean age of the cohort was 58 years. Fifty-eight percent (23 of 40) were male. When the clinicians were instructed to rate each side of the pharynx as normal, diminished, or absent, the interobserver and intraobserver reliabilities were poor (63% to 68% agreement; kappa = 0.18 to 0.67). When the clinicians were asked to rate the pharyngeal squeeze maneuver as normal or abnormal, both interobserver and intraobserver reliabilities were excellent (85% to 98% agreement; kappa = 0.75 to 0.95). Conclusions: The pharyngeal squeeze maneuver displayed poor reliability when motor function was classified into unilateral or bilateral normal, diminished, and absent categories. The pharyngeal squeeze maneuver was very reliable when simply graded as normal or abnormal. Clinicians could not reliably distinguish between diminished and absent pharyngeal motor functions.

Abstract
Objectives: Unsedated office-based laryngeal laser surgery (UOLS) is now an effective alternative to traditional operating room-based suspension microdirect laryngoscopy under general anesthesia. This procedure includes pulsed dye laser (PDL) treatment of recurrent respiratory papillomas, granulomas, leukoplakia, and polypoid degeneration. The objective of this study was to determine the magnitude of the cost savings derived by moving these types of procedures from the operating room to the office setting. Methods: Retrospective cost-identification analysis was performed by comparing the billing records of patients who underwent surgical laser treatment for recurrent respiratory papillomatosis in the operating room to the costs and charges for patients who underwent similar procedures with the in-office PDL. Results: In performing surgery with the PDL in the office, the average cost savings was more than $5,000 per case. Current reimbursement rates do not cover the cost of performing UOLS. Conclusions: The potential cost savings of UOLS are tremendous; however, at present significant financial disincentives prevent proliferation of this technology.

Abstract
INTRODUCTION: Recent advances in technology have facilitated a movement toward unsedated in-office treatment of laryngeal, tracheal, and esophageal lesions. The objective of this study was to determine patient tolerance of inoffice pulsed-dye laser (PDL) treatment of upper aerodigestive tract pathoses via the transnasal esophagoscope. METHODS: Three hundred twenty-eight unsedated in-office PDL cases were performed at a university-based tertiary referral center in 131 patients. These procedures were performed for various upper aerodigestive pathoses, including recurrent respiratory papillomatosis, chronic granulomas, and recurrent leukoplakia. Eighty-nine subjects completed a phone survey concerning their discomfort level after the PDL procedure. They were also asked specific questions about recovery time, pain medication, and preference of operating room versus inoffice procedures. RESULTS: The average comfort score was 7.4 (10 being minimal discomfort). Eighty-four percent did not use any pain medication; 87% stated that, if possible, they would prefer to undergo unsedated inoffice procedures rather than surgeries under general anesthesia for further treatment of their upper aerodigestive tract pathosis. CONCLUSIONS: Unsedated transnasal treatment of upper aerodigestive tract pathoses is readily accepted and well-tolerated by otolaryngology patients. Patients overwhelmingly prefer the inoffice PDL over surgeries under general anesthesia.

Abstract
OBJECTIVE: The microdebrider has been described for treating laryngeal papillomas, but there are no reports of other uses for this instrument in the pediatric airway. The objective of this article is to describe expanding applications for the microdebrider in pediatric airway surgery. STUDY DESIGN AND SETTING: Retrospective review, tertiary care academic institution. RESULTS: The microdebrider was used in 75 pediatric airway procedures. Twenty-two of these cases involved novel, previously unreported applications of the microdebrider. CONCLUSIONS: The microdebrider can be used safely and effectively for a variety of pediatric airway pathologies, including papillomas, granulations, and stenoses from the larynx to the distal trachea. SIGNIFICANCE: Correct usage of the various tip configurations on the microdebrider has made management of many airway lesions commonly encountered by pediatric otolaryngologists safer, more expedient, and simpler than management by other methods. In our practice, this instrument largely has supplanted the use of the CO2 laser and some open approaches for pediatric airway lesions.

Abstract
Objectives To determine the utility of spectral analysis in the differentiation of adductor-type spasmodic dysphonia (AdSD) from muscle tension dysphonia (MTD). Study Design Prospective blinded study. Methods Forty-seven samples of AdSD-connected speech spectrograms from 27 subjects and 17 samples of MTD-connected speech spectrograms from 15 subjects were selected from clinical charts and de-identified. These spectrograms were reviewed independently and blindly by two speech language pathologists experienced in spectrography. The speech language pathologists designated the spectrogram as consistent with AdSD and MTD, and these designations were compared with actual clinical diagnoses. Results The ability to differentiate AdSD from MTD with spectral analysis was 94% for rater #1 and 98% for rater #2. No MTD subjects were incorrectly diagnosed as having SD (100% specificity). Conclusions This study suggests that experienced speech language pathologists can distinguish AdSD from MTD with a high degree of sensitivity and specificity based on spectral analysis. Spectral analysis is especially useful in cases where perceptual analysis and clinical evaluation alone are insufficient.

Abstract
BACKGROUND: Unsedated office-based laser surgery (UOLS) of the larynx and trachea has significantly improved the treatment options for patients with laryngotracheal pathology including recurrent respiratory papillomas, granulomas, leukoplakia, and polypoid degeneration. UOLS delivered by flexible endoscopes has dramatically impacted office-based surgery by reducing the time, costs, and morbidity of surgery. OBJECTIVES: To review our experience with 443 laryngotracheal cases treated by UOLS. METHODS: The laser logbooks at the Center for Voice and Swallowing Disorders were reviewed for UOLS, and the medical and laryngological histories were detailed, as were the treatment modalities, frequencies, and complications. RESULTS: Of the 443 cases, 406 were performed with the pulsed-dye laser, 10 with the carbon-dioxide laser, and 27 with the thulium: yttrium-aluminum-garnet laser. There were no significant complications in this series. A review of indications and wavelength selection criteria is presented. CONCLUSION: Unsedated, office-based, upper aerodigestive tract laser surgery appears to be a safe and effective treatment option for many patients with laryngotracheal pathology.

Abstract
Background: Colorectal cancers (CRCs) detected through the NHS Bowel Cancer Screening Programme (BCSP) have been shown to have a more favourable outcome compared to non-screen-detected cancers. The aim was to identify whether this was solely due to the earlier stage shift of these cancers, or whether other factors were involved. Methods: A combination of a regional CRC registry (Northern Colorectal Cancer Audit Group) and the BCSP database were used to identify screen-detected and interval cancers (diagnosed after a negative faecal occult blood test, before the next screening round), diagnosed between April 2007 and March 2010, within the North East of England. For each Dukes' stage, patient demographics, tumour characteristics, and survival rates were compared between these two groups. Results: Overall, 322 screen-detected cancers were compared against 192 interval cancers. Screen-detected Dukes' C and D CRCs had a superior survival rate compared with interval cancers (P=0.014 and P=0.04, respectively). Cox proportional hazards regression showed that Dukes' stage, tumour location, and diagnostic group (HR 0.45, 95% CI 0.29–0.69, P<0.001 for screen-detected CRCs) were all found to have a significant impact on the survival of patients. Conclusions: The improved survival of screen-detected over interval cancers for stages C and D suggest that there may be a biological difference in the cancers in each group. Although lead-time bias may have a role, this may be related to a tumour's propensity to bleed and therefore may reflect detection through current screening tests.

Abstract
BACKGROUND Large sessile or flat colonic polyps, defined as polyps at least 20 mm in size, are difficult to treat endoscopically and may harbour malignancy. The aim of this study was to describe their current management to provide insight into optimal management. METHODS This retrospective observational study identified patients with large sessile or flat polyps detected in the English Bowel Cancer Screening Programme between 2006 and 2009. Initial therapeutic modality (surgical or endoscopic), subsequent management and outcomes were recorded. The main outcome measures analysed were: presence of malignancy, need for surgical treatment, complications, and residual or recurrent polyp at 12 months. RESULTS In total, 557 large sessile or flat polyps with benign appearance or initial histology were identified in 557 patients. Some 436 (78.3 per cent) were initially managed endoscopically and 121 (21.7 per cent) were managed surgically from the outset. Seventy of those initially treated endoscopically subsequently required surgery owing to the presence of malignancy (19) or not being suitable for further endoscopic management (51). Residual or recurrent polyp was present at 12 months in 26 (6.0 per cent) of 436 patients managed endoscopically. There was wide variation between centres in the use of surgery as a primary therapy, ranging from 7 to 36 per cent. Endoscopic complications included bleeding in 13 patients (3.0 per cent) and perforation in two (0.5 per cent). CONCLUSION Management of large sessile or flat colonic polyps is safe and effective in the English Bowel Cancer Screening Programme. Wide variation in the use of surgery suggests a need for standardized management algorithms. Presented to a meeting of the British Society of Gastroenterology, Birmingham, U.K., March 2011.

Abstract
AIM Current British guidelines recommend surveillance colonoscopy at 12 months for individuals found to have five or more adenomas, or three or more adenomas of which at least one is ≥ 1 cm in size. This study describes the yield of surveillance colonoscopy in this group and explores patient and clinical factors that may be associated with the presence of advanced adenomas or cancer at surveillance. METHOD Data were retrieved from the national database of the National Health Service Bowel Cancer Screening Programme. The detection of advanced colonic neoplasia (ACN, cancer or advanced adenoma) was used as the main outcome variable. Multivariable analysis was used to analyse relationships between patient factors (age, gender, body mass index, smoking and alcohol use) and clinical findings (number, size and nature of adenomas detected during index colonoscopy) with the outcome variable. RESULTS One-thousand, seven-hundred and sixty individuals were included in the study. The yield of ACN at 12-month surveillance was 6.6% (116/1760), of which 14/1760 (0.8%) had colorectal cancer. Nine (64.3%) of these 14 cancers were Dukes A at diagnosis. The presence of a villous adenoma or a right-sided adenoma at screening colonoscopy was associated with ORs of 1.98 (95% CI: 1.11-3.53, P = 0.012) and 1.76 (95% CI: 1.13-2.74, P = 0.020), respectively, for detection of ACN at surveillance. CONCLUSION Twelve-month surveillance colonoscopy is necessary in this group of patients. The presence of villous or proximal lesions at baseline is associated with increased risk of ACN at surveillance. Site and histological type of baseline lesions may be relevant for determining the surveillance interval.

Abstract
BACKGROUND AND STUDY AIMS Increasing colonoscopy withdrawal time (CWT) is thought to be associated with increasing adenoma detection rate (ADR). Current English guidelines recommend a minimum CWT of 6 minutes. It is known that in the Bowel Cancer Screening Programme (BCSP) in England there is wide variation in CWT. The aim of this observational study was to examine the relationship between CWT and ADR. PATIENTS AND METHODS The study examined data from 31 088 colonoscopies by 147 screening program colonoscopists. Colonoscopists were grouped in four levels of mean CWT ( < 7, 7 - 8.9, 9 - 10.9, and ≥ 11 minutes). Univariable and multivariable analysis (binary logistic and negative binomial regression) were used to explore the relationship between CWT, ADR, mean number of adenomas and number of right-sided and advanced adenomas. RESULTS In colonoscopists with a mean CWT < 7 minutes, the mean ADR was 42.5 % compared with 47.1 % in the ≥ 11-minute group (P < 0.001). The mean number of adenomas detected per procedure increased from 0.77 to 0.94, respectively (P < 0.001). The increase in adenoma detection was mainly of subcentimeter or proximal adenomas; there was no increase in the detection of advanced adenomas. Regression models showed an increase in ADR from 43 % to 46.5 % for mean CWT times ranging from 6 to 10 minutes. CONCLUSIONS This study demonstrates that longer mean withdrawal times are associated with increasing adenoma detection, mainly of small or right-sided adenomas. However, beyond 10 minutes the increase in ADR is minimal. Mean withdrawal times longer than 6 minutes are not associated with increased detection of advanced adenomas. Withdrawal time remains an important quality metric of colonoscopy.

Abstract
AIM Completeness and thoroughness of colonoscopy are measured by the caecal intubation rate (CIR) and the adenoma detection rate (ADR). National standards are ≥ 90% and ≥ 10% respectively. Variability in CIR and ADR have been demonstrated but comparison between individuals and units is difficult. We aimed to assess the performance of colonoscopy in endoscopy units in the northeast of England. METHOD Data on colonoscopy performance and sedation use were collected over 3 months from 12 units. Colonoscopies performed by screening colonoscopists were included for the CIR only. Funnel plots with upper and lower 95% confidence limits for CIR and ADR were created. RESULTS CIR was 92.5% (n = 5720) and ADR 15.9% (n = 4748). All units and 128 (99.2%) colonoscopists were above the lower limit for CIR. All units achieved the ADR standard with 10 above the upper limit. Ninety-nine (76.7%) colonoscopists were above 10%, 16 (12.4%) above the upper limit and 7 (5.4%) below the lower limit. Median medication doses were 2.2 mg midazolam, 29.4 mg pethidine and 83.3 μg fentanyl. In all, 15.1% of colonoscopies were unsedated. Complications were bleeding (0.10%) and perforation (0.02%). There was one death possibly related to bowel preparation. CONCLUSION Results indicate that colonoscopies are performed safely and to a high standard. Funnel plots can highlight variability and areas for improvement. Analyses of ADR presented graphically around the global mean suggest that the national standard should be reset at 15%.

Abstract
AIM The National Health Service Bowel Cancer Screening Programme (BCSP) aims to detect earlier stage cancer in asymptomatic individuals. Early experience suggested that many participants had lower gastrointestinal symptoms before screening. The study evaluated the prevalence of lower gastrointestinal symptoms and consultation behaviour among individuals undergoing colonoscopy at the South of Tyne BCSP Centre. METHOD Data were collected on all undergoing clinic assessment and colonoscopy. Symptoms were categorized as altered bowel habit (ABH), rectal bleeding (RB), abdominal pain (AP) and unexplained weight loss (UWL). RESULTS Symptoms were present in 65.1% (492/756) of subjects, 64.4% (431/669) of those with a non-cancer diagnosis and 70.1% (61/87) of those with cancer. Among those with a non-cancer diagnosis, symptoms were ABH in 52% (224/431), RB in 81.4% (351/431), AP in 15.3% (66/431) and UWL in 3.0% (13/431). In those with cancer symptoms they were ABH in 33.3% (29/87), RB in 55.2% (48/87) and AP in 11.5% (10/87). There was no significant difference in the prevalence of symptoms in those with a cancer or non-cancer diagnosis. A total of 34.2% (157/459) of individuals with symptoms had consulted their general practitioner, 28.1% (16/57) of those with cancer and 35.1% (141/402) without. CONCLUSION A large proportion of individuals colonoscoped in the BCSP reported symptoms predating screening. Their prevalence did not differ significantly between cancer and non-cancer diagnoses. The majority had not consulted their general practitioner. Health promotion regarding the importance of lower gastrointestinal symptoms and a risk assessment tool to help select those needing urgent specialist assessment are required.

Abstract
Background: The NHS Bowel Cancer Screening Programme (BCSP) offers biennial faecal occult blood testing (FOBt) followed by colonoscopy after positive results. Colorectal cancers (CRCs) registered with the Northern Colorectal Cancer Audit Group database were cross-referenced with the BCSP database to analyse their screening history. Methods: The CRCs in the screening population between April 2007 and March 2010 were identified and classified into four groups: control (diagnosed before first screening invite), screen-detected, interval (diagnosed between screening rounds after a negative FOBt), and non-uptake (declined screening). Patient demographics, tumour characteristics and survival were compared between groups. Results: In all, 511 out of 1336 (38.2%) CRCs were controls; 825 (61.8%) were in individuals invited for screening of which 322 (39.0%) were screen detected, 311 (37.7%) were in the non-uptake group, and 192 (23.3%) were interval cancers. Compared with the control and interval cancer group, the screen-detected group had a higher proportion of men (P=0.002, P=0.003 respectively), left colon tumours (P=0.007, P=0.003), and superior survival (both P<0.001). There was no difference in demographics, tumour location/stage, or survival between control and interval groups. Conclusion: The FOBt is better at detecting cancers in the left colon and in men. The significant numbers of interval cancers weren’t found to have an improved outcome compared with the non-screened population.

Abstract
OBJECTIVE The NHS Bowel Cancer Screening Programme (BCSP) began roll-out in 2006 aiming to reduce cancer mortality through detection at an earlier stage. We report results from the prevalent round of screening at two first wave centres and compare with the UK pilot study. DESIGN This is a service evaluation study. Data were collected prospectively for all individuals undergoing faecal occult blood testing (FOBt) and colonoscopy including: uptake and outcomes of FOBt, colonoscopic performance, findings, histological data and complications. Continuous data were compared using a two-tailed test of two proportions. SETTING The South of Tyne and Tees Bowel Cancer Screening centres. PATIENTS Participants of the BCSP. MAIN OUTCOME MEASURES 1) Colonoscopy Quality Assurance and 2) Cancer stage shift. RESULTS 195,772 individuals were invited to participate. Uptake was 54% and FOBt positivity 1.7%. 1524 underwent colonoscopy with caecal intubation in 1485 (97%). 180 (12%) cancers were detected. Dukes stages were: 76 (42%) A; 47 (26%) B; 47 (26%) C; 8 (4%) D and 2 (1%) unknown. This demonstrates a significantly earlier stage at diagnosis compared with data from 2867 non-screening detected cancers (p<0.001). Adenomas were detected in 758 (50%). One perforation occurred (0.07%) and two intermediate bleeds requiring transfusion only (0.12%). Both caecal intubation and adenoma detection were significantly higher than in the UK pilot study (p<0.001). CONCLUSIONS The prevalent round of screening demonstrates a high adenoma and cancer detection rate and significantly earlier stage at diagnosis. Complications were few providing reassurance regarding safety. Efforts are required to improve uptake.

Abstract
OBJECTIVE: The goal of this study is to review our series of head and neck paragangliomas to identify factors that may help in predicting malignancy. STUDY DESIGN: Case series with chart review. SETTING: Academic medical center. SUBJECTS AND METHODS: Subjects with head and neck paragangliomas at our institution from 1976 to current were reviewed. In addition to statistical comparisons of epidemiologic factors, pathologic and radiographic characteristics were reviewed. RESULTS: Of the 84 subjects, there were seven malignant paragangliomas (8%). Age was found to be significantly different between the benign and malignant subgroups, with an average age of 54 ± 16 and 40 ± 12 years, respectively ( P = 0.02). Pain was a presenting complaint in five patients with benign disease (6%), and five of the seven malignant patients (71%) presented with pain, showing a significant association between pain and disease type ( P <0.0001). The odds ratio for a patient with pain having a malignant tumor was 36 (95% CI: 5.5–234). Enlarging neck mass was noted in all cases of malignant disease, but only in 31 percent of cases of benign disease ( P < 0.0001). In a secondary analysis of carotid body tumors alone, enlarging neck mass was not found to be significant between benign and malignant disease ( P = 0.14). However, pain continued to be significantly different, with 67 percent of malignant lesions demonstrating pain, compared with only 11 percent of benign lesions ( P = 0.01). CONCLUSION: This study suggests that pain, a rapidly enlarging neck mass, and younger age are predictive factors of underlying malignancy, which should prompt one to consider an aggressive diagnostic and management approach.

Abstract
OBJECTIVE: To determine the prevalence of esophageal pathology following treatment for primary head and neck cancer (HNCA). STUDY DESIGN: Case series with planned data collection. SETTING: Academic medical practice. SUBJECTS AND METHODS: Subjects comprised HNCA survivors. Esophagoscopy was prospectively performed on 100 patients at least three months after treatment for HNCA. Patient demographics including cancer stage, cancer treatment, use of reflux medications, symptoms surveys, and esophageal findings were prospectively determined. RESULTS: The mean age of the cohort was 64 (± 10) years; 75 percent were male. The mean time between the end of treatment and endoscopy was 40 (± 51) months. Eighty-one percent of HNCA was advanced stage (3 or 4). The distribution of site of the primary HNCA was as follows: oropharynx (38%), larynx (33%), oral cavity (17%), unknown primary (10%), hypopharynx (1%), and nasopharynx (1%). Treatment modalities included surgery alone (15%), surgery with radiation (34%), radiation alone (6%), chemoradiation alone (24%), and chemoradiation with surgery (20%). The findings on esophagoscopy included peptic esophagitis (63%), stricture (23%), candidiasis (9%), Barrett metaplasia (8%), gastritis (4%), and carcinoma (4%). Only 13 percent had a normal esophagoscopy. CONCLUSION: Esophageal pathology is extremely common in patients treated for HNCA. These findings support routine esophageal screening after HNCA treatment. © 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation. All rights reserved.

Abstract
We describe a previously unreported phenomenon: positional dysphagia secondary to a Chiari I malformation. A 38-year-old woman presented with progressive dysphagia and cough. Flexible endoscopic evaluation of swallowing detected severe pharyngeal dysphagia and aspiration, as well as an intermittent cough reflex with all consistencies in the upright position. Various compensatory strategies were attempted to relieve the aspiration, but only assumption of the supine position was successful. Subsequent magnetic resonance imaging detected a herniation of the cerebellar tonsils to the level of C2 and the presence of a cervical syrinx-findings consistent with a Chiari I malformation. After surgical decompression of the malformation, the patient's symptoms completely resolved.

Abstract
OBJECTIVES/HYPOTHESIS Prolonged obstruction at the level of the lower esophageal sphincter is associated with a dilated, poorly contractile esophagus. The association between prolonged obstruction at the level of the upper esophageal sphincter (UES) and dilation and diminished contractility of the pharynx is uncertain. The purpose of this investigation was to evaluate the association between prolonged obstruction at the level of the UES and dilation and diminished contractility of the pharynx. STUDY DESIGN Case-control study. METHODS The fluoroscopic swallow studies of all persons with cricopharyngeus muscle dysfunction (CPD) diagnosed between January 1, 2006 and December 31, 2008 were retrospectively reviewed from a clinical database. Three categories of CPD were defined: nonobstructing cricopharyngeal bars (CPBs), obstructing CPBs, and Zenker diverticulum (ZD). The primary outcome measure was the pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength on fluoroscopy. Secondary outcome measures included pharyngeal area in the lateral fluoroscopic view and UES opening. The outcome measures were compared between groups and to a cohort of nondysphagic age- and gender-matched controls with the analysis of variance. RESULTS A total of 100 fluoroscopic swallow studies were evaluated. The mean age (+ or -standard deviation) of the cohort was 70 years (+ or -10 years). Thirty-six percent were female. The mean PCR progressively increased, indicating diminishing pharyngeal strength, from the normal (0.08), to the nonobstructing CPB (0.13), to the obstructing CPB (0.22), to the ZD group (0.28) (P < .001 with trend for linearity). There was a linear increase in pharyngeal area from the normal (8.75 cm(2)) to the nonobstructing CPB (10.00 cm(2)), to the obstructing CPB (10.46 cm(2)), to the ZD group (11.82 cm(2)) (P < .01 with trend for linearity). CONCLUSIONS The data suggest that there is an association between cricopharyngeus muscle dysfunction and progressive dilation and weakness of the pharynx. Laryngoscope, 2010.

Abstract
OBJECTIVES Office-based lasers have revolutionized the treatment of laryngeal disease. The 980-nm Gold laser is a device that may offer some practical advantages over other office lasers. The chick chorioallantoic membrane has been proposed as a model for predicting the effects of photoangiolytic lasers on vocal fold microvasculature. We sought to evaluate the effects of the Gold laser in this model. METHODS Vascular reactions in first-order vessels were determined for the Gold laser with both 0 degree straight and 30 degrees angled laser fibers. Vessels were treated at 15 W and a 500-ms pulse interval, with a 1-mm working distance. Pulse widths of 300 ms and 500 ms were evaluated. All vessels were treated until selective coagulation or vessel rupture. RESULTS We performed 60 trials on 30 embryos. The mean energy delivered was 33.7 J for the straight fiber and 51.2 J for the angled fiber. The laser achieved selective vessel coagulation without rupture in 100% (30 of 30) of straight fiber trials and in 100% (30 of 30) of angled fiber trials. In 6.7% (2 of 30) of straight fiber and 10% (3 of 30) of angled fiber trials, it caused minor injury to the surrounding albumin as indicated by white coagulum outside the vessel. CONCLUSIONS The Gold laser effectively coagulates small vessels without rupture at a working distance of 1 mm and settings of 15 W, 500-ms pulse interval, and 300- to 500-ms pulse width.

Abstract
The pharyngeal constriction ratio (PCR), derived directly from videofluoroscopy without the need for manometry, requires validation as a surrogate for pharyngeal strength. A correlation of −0.70 was previously identified between PCR and pharyngeal clearing pressures (PP) on separate fluoroscopic and manometric studies. As PP increases, PCR decreases. The objective of the current study was to evaluate the correlation between PCR and PP in 25 patients undergoing simultaneous fluoroscopy and pharyngeal manometry. The effect of the manometric catheter on PCR was also investigated. The correlation between the PCR and averaged pharyngeal clearing pressures was −0.72 (p < 0.001). All patients with a PCR > 0.25 had a PP < 60 mmHg. PCR did not differ significantly as a consequence of the manometric catheter. Results suggest the utility of an objective fluoroscopic measure in assessing pharyngeal strength when manometry may not be available or possible.

Abstract
Objectives: Postviral vagal neuropathy (PVVN) is a clinical diagnosis characterized by laryngeal complaints initiated by an upper respiratory tract infection (URI). Little is known about the natural history of this disease, and only small case series have been reported. We describe the clinical presentation, symptoms, patient demographics, and natural history of PVVN. Methods: A cross-sectional survey of all patients with a diagnosis of PVVN from January 1, 2006, to December 31, 2006, was prospectively administered, detailing disease onset, type and duration of symptoms, demographics, and previous treatment. The Reflux Symptom Index, Voice Handicap Index, and laryngoscopic findings were collected for each patient. Results: Forty-four patients with PVVN were identified. The mean age (±SD) was 48 ± 13 years, and 73% of the patients were female. The most common initial URI symptoms were cough (89%), nasal congestion (75%), and rhinorrhea (64%). Fifty-nine percent of the patients took antibiotics, and the mean time between symptom onset and presentation to the laryngologist was 83 ± 127 weeks. The most common persistent symptoms were cough (52%), throat clearing (48%), dysphonia (41.5%), and vocal fatigue (43%). Fifty-seven percent of the patients consulted 3 or more physicians for their symptoms. The mean Voice Handicap Index was 13.4 ± 10.3, and the mean Reflux Symptom Index was 17.7 ± 11. Fortynine percent of the patients had evidence of vocal fold paresis on strobovideolaryngoscopy. Conclusions: PVVN is a clinical entity characterized by a complex of laryngeal symptoms that begin after a URI. The symptoms include chronic cough, excessive throat clearing, dysphonia, and vocal fatigue. Affected individuals are typically in their fifth decade of life and appear more likely to be women. Most patients have seen multiple physicians, and the time to laryngologist referral is often delayed.

Abstract
Objectives: The Eating Assessment Tool is a self-administered, symptom-specific outcome instrument for dysphagia. The purpose of this study was to assess the validity and reliability of the 10-item Eating Assessment Tool (EAT-10). Methods: The investigation consisted of 4 phases: 1) line-item generation, 2) line-item reduction and reliability, 3) normative data generation, and 4) validity analysis. All data were collected prospectively. Internal consistency was assessed with the Cronbach alpha. Test-retest reliability was evaluated with the Pearson product moment correlation coefficient. Normative data were obtained by administering the instrument to a community cohort of healthy volunteers. Validity was assessed by administering the instrument before and after dysphagia treatment and by evaluating survey differences between normal persons and those with known diagnoses. Results: A total of 629 surveys were administered to 482 patients. The internal consistency (Cronbach alpha) of the final instrument was 0.960. The test-retest intra-item correlation coefficients ranged from 0.72 to 0.91. The mean (±SD) EAT-10 score of the normal cohort was 0.40 ± 1.01. The mean EAT-10 score was 23.58 ± 13.18 for patients with esophageal dysphagia, 23.10 ± 12.22 for those with oropharyngeal dysphagia, 9.19 ± 12.60 for those with voice disorders, 22.42 ± 14.06 for those with head and neck cancer, and 11.71 ± 9.61 for those with reflux. The patients with oropharyngeal and esophageal dysphagia and a history of head and neck cancer had a significantly higher EAT-10 score than did those with reflux or voice disorders (p < 0.001). The mean EAT-10 score of the patients with dysphagia improved from 19.87 ± 10.5 to 5.2 ± 7.4 after treatment (p < 0.001). Conclusions: The EAT-10 has displayed excellent internal consistency, test-retest reproducibility, and criterion-based validity. The normative data suggest that an EAT-10 score of 3 or higher is abnormal. The instrument may be utilized to document the initial dysphagia severity and monitor the treatment response in persons with a wide array of swallowing disorders.

Abstract
Objectives: Giant fibrovascular polyps of the esophagus are rare benign tumors originating from the proximal esophagus. These pedunculated lesions can grow to “giant” proportions. Asphyxiation from aspiration of the regurgitated polyp is a well-described cause of death. Traditional excision has involved a transcervical vertical esophagotomy. This report describes the successful endoscopic removal of a giant fibrovascular polyp of the esophagus. Results: A 63-year-old man with dwarfism and obstructive sleep apnea was referred for evaluation of an esophageal mass that was intermittently regurgitated into the hypopharynx. Office esophagoscopy demonstrated a 10-cm giant fibrovascular polyp originating just below the cricoid cartilage. During endoscopic removal, the base of the lesion was exposed with a Weerda bivalved laryngoscope. Bipolar cautery combined with a snare was used to transect the base with excellent hemostasis. No esophageal leak was noted on an esophagogram on postoperative day 3. The patient then resumed a liquid diet and was discharged home, resuming a regular diet within a week. Conclusions: Giant fibrovascular polyps of the esophagus are life-threatening because of potential airway obstruction. This report describes the successful endoscopic removal of a giant fibrovascular polyp, avoiding the potential morbidity associated with a transcervical vertical esophagotomy.

Abstract
Laryngopharyngeal reflux (LPR) is the disease process by which gastric contents affect the extraesophageal structures of the head and neck. The symptoms of LPR include intermittent dysphonia, excessive throat clearing, globus pharyngeus, cough, and dysphagia. These symptoms can be assessed with the Reflux Symptom Index. Signs of LPR, as determined with laryngoscopy, can be described with the Reflux Findings Score, which includes assessment of site-specific laryngeal edema and other inflammatory changes. This article discusses the current understanding of LPR pathophysiology, taking into account pepsin stability and reactivation.

Abstract
OBJECTIVE Conventional cuffed tracheotomy tubes do not prevent aspiration of secretions. Aspiration of saliva may be decreased with the use of a subglottic suction port. STUDY DESIGN Prospective. METHODS Shiley Disposable Cuffed Tracheotomy (DCT) tubes sizes 4, 6, and 8 (Tyco Healthcare, Pleasanton, CA) were compared to Portex Blue Line Ultra Suctionaid (BLUS) tracheotomy tubes sizes 6, 7, and 8 (Fig 1; Smiths Medical, Watford, UK). All tubes were tested in a simulated tracheal model using 10 cc of human saliva with no suction, intermittent suction, and constant suction (15 minutes). RESULTS There was a significant decrease in aspirate between the larger Shiley and BLUS tubes with intermittent suction (mean 8.38 mL Shiley 6 vs 1.60 mL BLUS 7; 8.50 mL Shiley 8 vs 2.80 mL BLUS 8). There was a significant decrease in aspirate between all sizes of Shiley and BLUS tubes with continuous suction. For BLUS 7 and 8, there was a significant difference between intermittent suction (mean, 1.60 mL, 2.80 mL, respectively) and continuous suction (mean, 0.20 mL, 0.60 mL respectively). Shiley and BLUS without suction were equivalent. CONCLUSION Subglottic suction tracheotomy tubes reduce the risk of aspiration beyond the cuff in a bench-top model.

Abstract
PURPOSE OF REVIEW Thin caliber transnasal esophagoscopes allow for a rapidly expanding array of office-based esophageal procedures, including botulinum toxin injections, in unsedated patients. RECENT FINDINGS While botulinum toxin has been used in the esophagus and lower esophageal sphincter for many years, there is no current description of performing this procedure in an unsedated patient using transnasal esophagoscopy. Indications include achalasia, hypertensive lower esophageal sphincter, distal esophageal spasm, nutcracker esophagus and obstructing muscular rings. There is a paucity of data in the literature pertaining to spastic esophageal motility disorders and muscular rings. Randomized controlled trials of achalasia treatments suggest that botulinum toxin injections should be reserved for patients who are poor surgical candidates and/or have failed pneumatic dilation. SUMMARY In-office transnasal esophagoscopy-guided lower esophageal sphincter botulinum toxin injection has not been described in the literature. Indications include esophageal spasm, muscular rings and achalasia, with recent data suggesting that botulinum toxin should not be an initial therapy for most patients with achalasia.

Abstract
Objectives: Management of the airway in an emergency may be a harrowing experience. The equipment necessary to perform this procedure is often inaccessible. The LifeStat emergency airway is a portable device approved by the US Food and Drug Administration in 1997 for emergency cricothyrotomy. It is small enough to secure to a keychain, thus allowing instantaneous access at all times. We present a retrospective case series to report the experience of clinicians who have used the LifeStat device. Methods: A survey instrument was sent to a convenience sample of health-care professionals who purchased the LifeStat emergency airway. The survey queried device use, user demographics, and the success, ease, complications, and location of use. Results: One thousand surveys were distributed, and 100 individuals responded. Fifteen percent (15 of 100) reported use of the device on 17 occasions. The LifeStat was used successfully in all 17 cases. Eighty-two percent (14 of 17) of emergency use was in hospitals. In all cases the device was positioned successfully on the first attempt. No complications were reported. Conclusions: The LifeStat device provides a relatively safe and effective means of performing emergency cricothyrotomy. The majority of emergency situations in which the device was deployed occurred in hospital settings.

Abstract
Laryngopharyngeal reflux (LPR) is the backflow of gastric contents into the pharynx and larynx. The diagnosis of LPR is primarily based on symptoms, including dysphonia, dysphagia, globus, throat-clearing, and post-nasal drip. The gold standard for diagnosis is dual-probe 24-hour pH testing with the upper probe positioned above the upper oesophageal sphincter. Treatment may require 3 months or more of twice-daily proton pump inhibitors along with lifestyle modifications. This review details the pathophysiology, symptoms, findings, treatment, and current controversies in LPR.

Abstract
OBJECTIVES To determine the prevalence of laryngopharyngeal (LP) abnormalities in hospitalized patients with dysphagia referred for flexible endoscopic evaluation of swallowing (FEES). STUDY DESIGN Retrospective, blinded review by two otolaryngologists of 100 consecutive FEES studies performed and video-recorded by a speech-language pathologist (SLP). METHODS Two otolaryngologists reviewed videos of 100 consecutive FEES studies on hospitalized patients with dysphagia for the presence of abnormal LP findings. RESULTS Sixty-one male and 38 female patients comprised the hospital dysphagia cohort. The mean age was 62. One subject could not be evaluated because of the severity of the retained secretions, leaving 99 subjects in the cohort. Seventy-six percent had been previously intubated, with a mean intubation duration of 13 days. The overall prevalence of abnormal LP findings was 79%. Forty-five percent of the patients presented with two or more findings, which included arytenoid edema (33%), granuloma (31%), vocal fold paresis (24%), mucosal lesions (17%), vocal fold bowing (14%), diffuse edema (11%), airway stenosis (3%), and ulcer (6%). There was a significant difference in LP findings between those individuals who had or had not been intubated. CONCLUSIONS Hospitalized patients with dysphagia are at high risk for LP abnormalities, particularly if they have been intubated, and may benefit from either 1) an initial joint examination by the SLP and otolaryngologist or 2) an otolaryngologist's review of the recorded examination conducted by the SLP. Such otolaryngology involvement could identify airway stenosis patients at an earlier stage, initiate granuloma treatment sooner, enable earlier biopsy of unexpected lesions, and allow follow-up of mucosal and neuromuscular findings that do not respond to medical management.
