Gastrointestinal dysmotility complicating Behçet's syndrome: description of a newly recognised clinical phenotype.

OBJECTIVES: Gastrointestinal dysmotility may arise in a variety of auto-immune and auto-inflammatory diseases and hitherto has not been described in Behçet's syndrome (BS). METHODS: We present data on a cohort of seven patients under our care who presented with symptoms of and investigations compatible with an immune associated disorder of gastrointestinal motility, or enteric neuropathy. RESULTS: We describe the clinical features and investigation results. We undertook a trial of a novel treatment in the disease, apheresis, and noted a response not only to the enteric neuropathy but also to the systemic features of the disease, despite previous maximal immunosuppressive therapy in most cases. CONCLUSIONS: Gastrointestinal dysmotility may arise in BS and is effectively treated by apheresis. The mechanism by which this response is made immunologically requires to be elucidated in future studies.

The peritoneal cancer index as a predictor of complete cytoreduction at primary and interval cytoreductive surgery in advanced ovarian cancer.

OBJECTIVE: The peritoneal cancer index quantitatively assesses cancer distribution and tumor burden in the peritoneal cavity. The aim of this study is to evaluate the association between the peritoneal cancer index and completeness of surgical cytoreduction for ovarian cancer and to identify a cut-off above which complete cytoreduction is unlikely. METHODS: This is a single-center prospective cohort observational study. A total of 100 consecutive patients who underwent ovarian cancer surgery were included. Peritoneal cancer index scores prior to and after surgery were calculated, and a cut-off value for incomplete cytoreduction was identified using a receiver operator characteristic (ROC) curve. Surgical complexity, blood loss, length of surgery, and complications were analyzed and associations with the peritoneal cancer index score were evaluated. RESULTS: The overall median peritoneal cancer index score was 9.5 (range 0-36). The median age of the patients was 61 years (range 24-85). The most common stage was III (13% stage II, 53% stage III, 34% stage IV) and the most common histologic sub-type was high-grade serous (76% high-grade serous, 8% low-grade serous, 5% clear cell, 4% serous borderline, 2% endometrioid, 2% adult granulosa cell, 2% adenocarcinoma, 1% carcinosarcoma). Complete cytoreduction was achieved in 82% of patients, with a median score of 9 (range 0-30). The remaining 18% had a median score of 28.5 (range 0-36). The best predictor of incomplete cytoreduction was the peritoneal cancer index score, with an area under the curve (AUC) of 0.928 (95% CI 0.85 to 1.00). ROC curve analysis determined a peritoneal cancer index cut-off score of 20. Major complications occurred in 15% of patients with peritoneal cancer index scores >20 and in 2.5% of patients with scores ≤20, which was statistically significant (p=0.014). CONCLUSIONS: In our study we found that a peritoneal cancer index score of ≤20 was associated with a high likelihood of complete cytoreduction. Incorporating the peritoneal cancer index into routine surgical practice and research may impact treatment plans.

The impact of nutritional risk factors and sarcopenia on survival in patients treated with pelvic exenteration for recurrent gynaecological malignancy: a retrospective cohort study.

PURPOSE: The aim of the present study is to investigate the prognostic significance of nutritional risk factors and sarcopenia on the outcome of patients with recurrent gynaecological malignancies treated by pelvic exenteration. METHODS: We retrospectively evaluated muscle body composite measurements based on pre-operative CT scans, nutritional risk factors as assessed by a validated pre-operative questionnaire, and clinical-pathological parameters in 65 consecutive patients with recurrent gynaecological malignancies, excluding ovarian cancer, treated by pelvic exenteration at the Royal Marsden Hospital London. Predictive value for postoperative morbidity was investigated by logistic regression analyses. Relevant parameters were included in uni- and multivariate survival analyses. RESULTS: We found only (1) low muscle attenuation (MA)-an established factor for muscle depletion-and (2) moderate risk for malnutrition to be independently associated with shorter overall survival (p = 0.006 and p = 0.008, respectively). MA was significantly lower in overweight and obese patients (p = 0.04). Muscle body composite measurements were not predictive for post-operative morbidity. CONCLUSION: The study suggests that pre-operative low MA and moderate risk for malnutrition are associated with shorter survival in patients with recurrent gynaecological malignancies treated with pelvic exenteration. Further studies are needed to validate these findings in larger cohorts.

Ovarian Extravascular Papillary Endothelial Hyperplasia (Masson Tumor) Mimicking a Primary Gynecologic Malignancy.

Papillary endothelial hyperplasia or Masson tumor most commonly occurs within the extremities and head and neck. It is usually of intravascular type, associated with thrombus formation and organization within a preexisting vessel or vascular malformation, but rarely can be extravascular. We describe the first 2 cases of this extravascular type to occur within the ovary, one of which mimicked malignancy radiologically. This condition is thought to represent a reactive phenomenon with reparative response secondary to thrombosis although with an unclear underlying pathogenesis. The prognosis is generally good, with complete surgical resection usually representing adequate treatment.

Laparoscopic assessment improves case selection for exenterative surgery in recurrent cervical and endometrial cancer.

The objective of this study is to evaluate the role of laparoscopy in the case selection of patients for pelvic exenteration to treat recurrent cervical or endometrial cancer. Pelvic exenteration is a rare surgical procedure performed by specialised multidisciplinary surgical teams. We performed a review of 55 consecutive laparoscopies for patients being evaluated for possible exenterative surgery for recurrent cervical or endometrial cancer at a single centre in the UK with a significant exenterative surgical practice. All patients had no evidence of metastatic disease on imaging prior to the laparoscopy. Despite thorough radiological assessment laparoscopy detected peritoneal, nodal or extrapelvic metastases in 20.8% of cases. 5.6% of the patients who underwent exenterative surgery were found to have unresectable pelvic disease intraoperatively. In these cases, the extent of disease was not determined radiologically or during the initial exploratory laparotomy. In our view, laparoscopic assessment is an essential component of the pre-operative work up of patients with recurrent cervical or endometrial cancer being considered for exenterative surgery.Impact statementWhat is already known on this subject? Pelvic exenteration is potentially curative in cases of recurrent pelvic malignancy. Case selection is essential to determine those patients without metastases and with resectable pelvic disease - this will improve patient outcomes, avoid the unnecessary morbidity of major surgery, as well as the psychological consequences of abandoned procedures. The only two previous studies, published in 1998 (Plante and Roy 1998) and 2002 (Köhler et al. 2002) have shown laparoscopic assessment to be safe and improve case selection.What do the results of this study add? This study provides evidence that in the context of modern imaging modalities, including PET-CT scans, laparoscopic assessment continues to improve case selection for exenterative surgery.What are the implications of these findings for clinical practice and/or further research? This study provides further evidence of the benefit of laparoscopy in the assessment of patients being considered for exenterative surgery for recurrent pelvic cancer. Routine laparoscopy improves case selection and will enhance patient experiences and outcomes.

Visualizing the autonomic and somatic innervation of the female pelvis with 3D MR neurography: a feasibility study.

BACKGROUND: Treatment of female pelvic malignancies often causes pelvic nerve damage. Magnetic resonance (MR) neurography mapping the female pelvic innervation could aid in treatment planning. PURPOSE: To depict female autonomic and somatic pelvic innervation using a modified 3D NerveVIEW sequence. MATERIAL AND METHODS: Prospective study in 20 female volunteers (n = 6 normal, n = 14 cervical pathology) who underwent a modified 3D short TI inversion recovery (STIR) turbo spin-echo (TSE) scan with a motion-sensitive driven equilibrium (MSDE) preparation radiofrequency pulse and flow compensation. Modifications included offset independent trapezoid (OIT) pulses for inversion and MSDE refocusing. Maximum intensity projections (MIP) were evaluated by two observers (Observer 1, Observer 2); image quality was scored as 2 = high, 1 = medium, or 0 = low with the sciatic nerve serving as a reference. Conspicuity of autonomic superior (SHP) and bilateral inferior hypogastric plexuses (IHP), hypogastric nerves, and somatic pelvic nerves (sciatic, pudendal) was scored as 2 = well-defined, 1 = poorly defined, or 0 = not seen, and inter-observer agreement was determined. RESULTS: Images were of medium to high quality according to both observers agreeing in 15/20 (75%) of individuals. SHP and bilateral hypogastric nerves were seen in 30/60 (50%) of cases by both observers. Bilateral IHP was seen in 85% (34/40) by Observer 1 and in 75% (30/40) by Observer 2. Sciatic nerves were well identified in all cases, while pudendal nerves were seen bilaterally by Observer 1 in 65% (26/40) and by Observer 2 in 72.5% (29/40). Agreement between observers for scoring nerve conspicuity was in the range of 60%-100%. CONCLUSION: Modified 3D NerveVIEW renders high-quality images of the female autonomic and pudendal nerves.

Neurosarcoidosis: clinical manifestations, investigation and treatment.

Sarcoidosis affects the nervous system in 10% of cases. When it does so it can affect any part of the nervous system and with all degrees of severity. It forms part of the differential diagnosis in inflammatory, infective, neoplastic and degenerative neurological diseases and may be very difficult to diagnose without histological confirmation. Recent clinical studies and the increasing availability of new biological treatments allow a much clearer understanding of the disease. This review summarises its clinical features, imaging and laboratory characteristics, treatment and outcome.

An Unusual Case of YWHAE-NUTM2A/B Endometrial Stromal Sarcoma With Confinement to the Endometrium and Lack of High-Grade Morphology.

Endometrial stromal sarcoma (ESS) characterized by YWHAE-NUTM2A/B genetic fusion is a recently recognized entity that is classified as a high-grade (HG) ESS in the 2014 World Health Organization Classification. These are myoinvasive neoplasms and typically contain a monomorphous HG round-cell cyclinD1-positive component with or without an accompanying low-grade (LG) component that is only focally positive/negative for cyclinD1. We report a case of YWHAE-NUTM2A/B ESS in a 46-yr-old woman that showed a number of unusual histologic features, including being entirely confined to the endometrium with no myoinvasion or lymphovascular space invasion. The initial hysteroscopic biopsy showed a cyclinD1-positive classic LG ESS-like component which merged with a smaller cyclinD1 negative/focally positive fibroblastic component with no HG areas. YWHAE-NUTM2A/B genetic fusion was shown by real-time quantitative polymerase chain reaction and Sanger sequencing. In the subsequent hysterectomy specimen, the tumor was entirely confined to the endometrium and was largely composed of cellular and classic LG ESS-like areas (80%) which were strongly and diffusely positive for cyclinD1 and a focal fibroblastic component (20%) which was largely cyclinD1 negative. Despite the cellular areas showing mild nuclear enlargement, the entire tumor had a very low mitotic and proliferation index and showed strong and diffuse positivity for estrogen and progesterone receptors. The patient remains alive and well with no evidence of disease 14 mo following diagnosis. To our knowledge, this is the first reported case of YWHAE-NUTM2A/B ESS that is confined to the endometrium and which exhibits entirely LG morphology.

Selective marginal resections in the management of aggressive angiomyxomas.

AIM: Aggressive angiomyxomas (AA) are rare tumors, most commonly presenting in the pelvis of women of childbearing age. This study presents the results of selective marginal resection of this disease in patients managed at a single institution. METHODS: Patients diagnosed with AA from July 2001 to July 2015 were identified from a prospectively maintained histopathology database. RESULTS: Seventeen patients were diagnosed with AA in the study period. The median age at diagnosis was 48 years. Females were more commonly affected with a M:F of 1:8.5. The most common differential diagnoses were an ischiorectal abscess or Bartholin's cyst. Fifteen cases occurred in the pelvis, with two cases at other sites. Median maximum tumor diameter was 10 cm. Of the pelvic cases, 12 were managed operatively via perineal, abdominal, or abdominoperineal approaches. Excision was performed in a marginal fashion with minimal morbidity. Local recurrence developed in 58.3% with a median local recurrence free survival of 25 months. No patients developed metastatic disease or died from disease. CONCLUSION: AA are rare tumors with a propensity for local recurrence. Atypical presentations of other perineal pathologies should prompt further investigation. Surgery should be reserved for symptomatic patients and is associated with low rates of morbidity. J. Surg. Oncol. 2016;114:828-832. © 2016 2016 Wiley Periodicals, Inc.

Outcome of Appendicectomies at Surgery for Mucinous Ovarian Neoplasms: Report From A UK Center and Review of Literature.

OBJECTIVE: This study aimed to determine the frequency of malignant pathology in a macroscopically normal appendix during surgery for a borderline or malignant mucinous ovarian tumor (MOT). METHODS: Women with borderline and malignant MOT were identified from the pathology database from 2000 to 2014. Women who had a benign MOT and had an appendicectomy were excluded from the study. Data were collected from the electronic patient record and case notes. RESULTS: Of 310 women identified with MOT, 203 patients with benign MOT were excluded. Of the remaining 107 patients, 15 patients with previous appendicectomy were also excluded. The study population consisted of 92 patients. There were 57 (62%) patients with borderline MOT and 35 (38%) patients with malignant MOT. In the borderline subgroup, 40/57 (70%) patients had appendicectomy of whom 8 (20%) had macroscopically abnormal appendices. One patient had pseudomyxoma peritonei secondarily involving the appendix and 7 patients had a histologically normal appendix. Normal histology was found in all macroscopically normal appendices. In the malignant subgroup, 29/35 (83%) patients had an appendicectomy. There were 8 (27.5%) macroscopically abnormal appendices with a malignant pathology in 7 (87.5%) patients and 1 patient had a resolving appendicitis. There were 21 macroscopically normal appendices of which, serrated adenoma was found in 1 (4.8%) patient, whereas the remaining 20 (95.2%) patients had normal histology. CONCLUSIONS: In MOT, an abnormal appearing appendix should be excised. If the appendix is grossly normal, our data do not support performing an appendicectomy as part of a surgical staging procedure.

Human Peritoneal Mesothelial Cells Display Phagocytic and Antigen-Presenting Functions to Contribute to Intraperitoneal Immunity.

Mesothelial cells lining the peritoneal cavity are strategically positioned to respond to and counter intraperitoneal infections, cancer cells, and other challenges. We have investigated human peritoneal mesothelial cells (HPMCs) for phagocytic activity, expression of surface Major Histocompatibility Complex (MHC) class II and accessory molecules involved in antigen presentation, and the ability to present recall antigens to T cells. Phagocytosis of dextran, latex beads, and Escherichia coli was observed by flow cytometry, and internalization was visualized using confocal and electron microscopy. Flow cytometry and/or cellular enzyme-linked immunosorbent assay showed constitutive expression of ICAM-1, LFA-3, and B7-1, but not B7-2 or MHC class II. Interferon-gamma induced MHC II and ICAM-1 expression in a dose- and time-dependent manner. Importantly, HPMCs induced autologous CD3 T-lymphocyte proliferation (H incorporation) after pulse with recall antigen. Human peritoneal mesothelial cells equipped with phagocytic and antigen-presenting machinery are anticipated to have an integral role in intraperitoneal immune surveillance.

Influence of food and lifestyle on the risk of developing inflammatory bowel disease.

BACKGROUND: The Barwon area in Australia has one of the highest incidence rates of inflammatory bowel disease (IBD) and therefore is an ideal location to study the impact of environmental exposures on the disease's development. AIM: To study these exposures prior to the development of IBD in a population-based cohort. METHOD: One hundred and thirty-two incident cases (81 Crohn disease (CD) and 51 ulcerative colitis (UC)) from an IBD registry and 104 controls replied to the International Organization of Inflammatory Bowel Diseases environmental questionnaire. This included 87 questions about pre-illness exposures that included childhood illnesses, vaccinations, breastfeeding, house amenities, pets and swimming, diet and smoking. RESULTS: The factors associated with CD included smoking (odds ratio (OR): 1.42, confidence interval (CI): 1-2.02, P = 0.029); childhood events, including tonsillectomy (OR: 1.74, CI: 1.15-2.6, P = 0.003) and chicken pox infection (OR: 3.89, CI: 1.61-9.4, P = 0.005) and pre-diagnosis intake of frequent fast food (OR: 2.26, CI: 1.76-4.33, P = 0.003). In UC, the risk factors included smoking (OR: 1.39, CI: 1.1-1.92, P = 0.026) and pre-diagnosis intake of frequent fast food (OR: 2.91, CI: 1.54-5.58, P < 0.001), and high caffeine intake was protective (OR: 0.51, 95% CI: 0.3-0.87, P = 0.002). Other protective exposures for UC included high fruit intake (OR: 0.59, CI: 0.4-0.88, P = 0.003) and having pets as a child (OR: 0.36, CI: 0.2-0.79, P = 0.001). CONCLUSION: This first Australian population-based study of environmental risk factors confirms that smoking, childhood immunological events and dietary factors play a role in IBD development; while high caffeine intake and pet ownership offer a protective effect.

Global DNA hypermethylation in down syndrome placenta.

Down syndrome (DS), commonly caused by an extra copy of chromosome 21 (chr21), occurs in approximately one out of 700 live births. Precisely how an extra chr21 causes over 80 clinically defined phenotypes is not yet clear. Reduced representation bisulfite sequencing (RRBS) analysis at single base resolution revealed DNA hypermethylation in all autosomes in DS samples. We hypothesize that such global hypermethylation may be mediated by down-regulation of TET family genes involved in DNA demethylation, and down-regulation of REST/NRSF involved in transcriptional and epigenetic regulation. Genes located on chr21 were up-regulated by an average of 53% in DS compared to normal villi, while genes with promoter hypermethylation were modestly down-regulated. DNA methylation perturbation was conserved in DS placenta villi and in adult DS peripheral blood leukocytes, and enriched for genes known to be causally associated with DS phenotypes. Our data suggest that global epigenetic changes may occur early in development and contribute to DS phenotypes.

Evaluation of the brain anaesthesia response monitor during anaesthesia for cardiac surgery: a double-blind, randomised controlled trial using two doses of fentanyl.

The brain anaesthesia response (BAR) monitor uses a method of EEG analysis, based on a model of brain electrical activity, to monitor the cerebral response to anaesthetic and sedative agents via two indices, composite cortical state (CCS) and cortical input (CI). It was hypothesised that CCS would respond to the hypnotic component of anaesthesia and CI would differentiate between two groups of patients receiving different doses of fentanyl. Twenty-five patients scheduled to undergo elective first-time coronary artery bypass graft surgery were randomised to receive a total fentanyl dose of either 12 µg/kg (fentanyl low dose, FLD) or 24 µg/kg (fentanyl moderate dose, FMD), both administered in two divided doses. Propofol was used for anaesthesia induction and pancuronium for intraoperative paralysis. Hemodynamic management was protocolised using vasoactive drugs. BIS, CCS and CI were simultaneously recorded. Response of the indices (CI, CCS and BIS) to propofol and their differences between the two groups at specific points from anaesthesia induction through to aortic cannulation were investigated. Following propofol induction, CCS and BIS but not CI showed a significant reduction. Following the first dose of fentanyl, CI, CCS and BIS decreased in both groups. Following the second dose of fentanyl, there was a significant reduction in CI in the FLD group but not the FMD group, with no significant change found for BIS or CCS in either group. The BAR monitor demonstrates the potential to monitor the level of hypnosis following anaesthesia induction with propofol via the CCS index and to facilitate the titration of fentanyl as a component of balanced anaesthesia via the CI index.

Treatment of refractory stomal variceal haemorrhage with embolisation and sclerosis.

Stomal variceal bleeding is a rare but life-threatening complication of cirrhosis. As it is an uncommon condition, there is little evidence on the optimum treatment. We report a case of parastomal variceal bleeding in a cirrhotic and haemodynamically unstable patient. The bleeding had failed to respond to local therapy and was not amenable to transjugular intrahepatic portosystemic shunting. The varix was successfully treated under radiological guidance embolisation in conjunction with Fibrovein (STD Pharmaceuticals, UK) sclerosis. We propose that Fibrovein sclerosis through angiography should be considered as an initial treatment option in patients with parastomal variceal bleeding who are not candidates for transjugular intrahepatic portosystemic shunting.

Glutamate quantification in patients with supratentorial gliomas using chemical shift imaging.

This study aimed to evaluate and validate chemical shift imaging (CSI) for in vivo glutamate (Glu) quantification in patients with supratentorial gliomas. If validated, CSI could become an extremely useful tool to investigate metabolic dysfunction of Glu in excitotoxic neuropathologies. Quantitative CSI estimates of Glu concentrations were compared with known concentrations of Glu in aqueous phantom solutions. Forty-one patients with known or likely supratentorial gliomas underwent preoperative CSI. The spectra obtained were analyzed for Glu concentrations and Glu to creatine (Cr) ratios. These in vivo measurements were correlated against ex vivo Glu content quantified by high performance liquid chromatography (HPLC) measured in 65 resected brain tumor and peritumoral brain specimens. For the phantom solutions the CSI estimates of Glu concentration and the Glu/Cr ratios were highly correlated with known Glu concentration (r² = 0.95, p = 0.002, and r² = 0.97, p < 0.0001, respectively). There was a modest, but statistically significant, correlation between the ex vivo measured Glu and in vivo spectroscopic Glu concentration (r² = 0.22, p = 0.04) and ratios of Glu to Cr (r² = 0.30, p = 0.002). Quantitative measurement of Glu content is feasible in patients with supratentorial gliomas using CSI. The in vitro and in vivo results suggest that this has the potential to be a reliable quantitative imaging assay for brain tumor patients. This may have wide clinical research applications in a number of neurological disorders where Glu excitotoxicity and metabolic dysfunction are known to play a role in pathogenesis, including tumor associated epilepsy, epilepsy, stroke and neurotrauma.

Exenterative surgery for recurrent gynaecological malignancies.

BACKGROUND: Cancer is a leading cause of death worldwide. Gynaecological cancers (i.e. cancers affecting the ovaries, uterus, cervix, vulva and vagina) are among the most common cancers in women. Unfortunately, given the nature of the disease, cancer can recur or progress in some patients. Although the management of early-stage cancers is relatively straightforward, with lower associated morbidity and mortality, the surgical management of advanced and recurrent cancers (including persistent or progressive cancers) is significantly more complicated, often requiring very extensive procedures. Pelvic exenterative surgery involves removal of some or all of the pelvic organs. Exenterative surgery for persistent or recurrent cancer after initial treatment is difficult and is usually associated with significant perioperative morbidity and mortality. However, it provides women with a chance of cure that otherwise may not be possible. In carefully selected patients, it may also have a place in palliation of symptoms. The biology of recurrent ovarian cancer differs from that of other gynaecological cancers; it is often responsive to chemotherapy and is not included in this review. OBJECTIVES: To evaluate the effectiveness and safety of exenterative surgery versus other treatment modalities for women with recurrent gynaecological cancer, excluding recurrent ovarian cancer (this is covered in a separate review). SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE up to February 2013. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of clinical guidelines and review articles and contacted experts in the field. SELECTION CRITERIA: Randomised controlled trials (RCTs) or non-randomised studies with concurrent comparison groups that included multivariate analyses of exenterative surgery versus medical management in women with recurrent gynaecological malignancies. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. No studies were found; therefore no data were analysed. MAIN RESULTS: The search strategy identified 1311 unique references, of which seven were retrieved in full, as they appeared to be potentially relevant on the basis of title and abstract. However, all were excluded, as they did not meet the inclusion criteria of the review. AUTHORS' CONCLUSIONS: We found no evidence to inform decisions about exenterative surgery for women with recurrent cervical, endometrial, vaginal or vulvar malignancies. Ideally, a large RCT or, at the very least, well-designed non-randomised studies that use multivariate analysis to adjust for baseline imbalances are needed to compare exenterative surgery versus medical management, including palliative care.

Inflammatory bowel disease cancer surveillance in a tertiary referral hospital: attitudes and practice.

BACKGROUND: Physician adherence to guidelines for colorectal cancer (CRC) surveillance in inflammatory bowel disease (IBD) is often poor. This may lead to adverse patient outcomes and excess endoscopic workload. AIMS: To assess the attitudes and practice of IBD specialists in a tertiary centre towards colonoscopic surveillance. METHODS: First, a questionnaire evaluating attitudes and approach to CRC surveillance was issued to 36 clinicians at one tertiary referral hospital. Second, a retrospective audit of IBD surveillance colonoscopy practice over a 2-year period was performed. RESULTS: Questionnaire response rate was 97%. Sixty-nine per cent of respondents were aware of, and used, Australian guidelines. Surveillance was undertaken by all clinicians in patients with extensive colitis, 83% in patients with left-sided colitis and 51% in patients with proctitis. Seventy-six per cent used chromoendoscopy, and 47% took 10 to 20 random biopsies. Colectomy was considered appropriate in 0% for unifocal low-grade dysplasia, 35% for multifocal low-grade dysplasia and 83% for high-grade dysplasia. Sixty-six per cent would remove elevated dysplastic lesions endoscopically. The audit identified 103 surveillance colonoscopies in 81 patients. Chromoendoscopy was used in 21% of cases, and the median number of random biopsies was 13. Sixty-two per cent of colonoscopies were performed outside the guidelines in relation to colonoscopic frequency. Following colonoscopy, an appropriate recommendation for subsequent surveillance was documented in 40% of cases. CONCLUSIONS: Knowledge and practice of CRC surveillance in IBD vary among specialist clinicians and often deviate from guidelines. Many clinicians perform surveillance earlier and more frequently than recommended. These findings have implications for patient outcomes and workload.

Perspectives of paediatric and adult gastroenterologists on transfer and transition care of adolescents with inflammatory bowel disease.

BACKGROUND: Programmes specific to inflammatory bowel disease (IBD) that facilitate transition from paediatric to adult care are currently lacking. AIM: We aimed to explore the perceived needs of adolescents with IBD among paediatric and adult gastroenterologists and to identify barriers to effective transition. METHODS: A web-based survey of paediatric and adult gastroenterologists in Australia and New Zealand employed both ranked items (Likert scale; from 1 not important to 5 very important) and forced choice items regarding the importance of various factors in facilitating effective transition of adolescents from paediatric to adult care. RESULTS: Response rate among 178 clinicians was 41%. Only 23% of respondents felt that adolescents with IBD were adequately prepared for transition to adult care. Psychological maturity (Mean = 4.3, standard deviation (SD) = 0.70) and readiness as assessed by adult caregiver (Mean = 4, SD = 0.72) were prioritised as the most important factors in determining timing of transfer. Self-efficacy and readiness as assessed by adult caregiver were considered the two most important factors to determine timing of transition by both groups of gastroenterologists. Poor medical and surgical handover (Mean = 4.10, SD = 0.8) and patients' lack of responsibility for their own care (Mean= 4.10, SD = 0.82) were perceived as major barriers to successful transition by both paediatric and adult gastroenterologists. CONCLUSIONS: Deficiencies exist in current transition care of adolescents with IBD in Australia and New Zealand. Standardising transition care practices with strategies aimed at optimising communication, patient education, self-efficacy and adherence may improve outcomes.
