Comparative study of characteristics and disease management between subjects with frequent and occasional gastro-oesophageal reflux symptoms.

BACKGROUND: Little is known about the distinctive characteristics of subjects with frequent (at least weekly) and occasional gastro-oesophageal reflux symptoms. AIM: To compare the characteristics and disease management of subjects complaining of at least weekly and less frequent gastro-oesophageal reflux symptoms. METHODS: Population-based postal survey carried out in France in 2003 among a representative sample of 8000 subjects. RESULTS: The prevalence of frequent and occasional gastro-oesophageal reflux symptoms was 7.8% and 23.4%, respectively. Compared to subjects with occasional gastro-oesophageal reflux symptoms, those with frequent symptoms were older, suffered from more severe symptoms and felt greater impact on daily living, despite a slightly shorter duration of symptoms. These subjects more often sought medical advice. Most of them had treated the last episode of symptoms primarily with a proton-pump inhibitor and less often with antacids/alginates. The degree of treatment satisfaction was lower in subjects with frequent gastro-oesophageal reflux symptoms, in relation to a more frequently observed persistence of symptoms irrespective of the medication used except for proton-pump inhibitors. CONCLUSIONS: This survey suggests that subjects complaining of frequent or occasional gastro-oesophageal reflux symptoms constitute two distinctive groups. Despite greater healthcare use, the former group shows a lower level of satisfaction with disease management. Nevertheless, a substantial subset of subjects with occasional symptoms also complained of impaired health-related quality of life and sought health care.

Wireless capsule endoscopy versus ileocolonoscopy for the diagnosis of postoperative recurrence of Crohn's disease: a prospective study.

BACKGROUND AND AIMS: Following ileocolonic resection for Crohn's disease (CD), early endoscopic recurrence predicts recurrence of symptoms. The aim of the study was to compare ileocolonoscopy and wireless capsule endoscopy (WCE) for the detection of postoperative recurrence in CD. METHODS: WCE and ileocolonoscopy were performed within six months following surgery in 32 prospectively enrolled patients. Two independent observers interpreted the results of WCE. Recurrence in the neoterminal ileum was defined by a Rutgeerts score>or=1. When observers at WCE did not concur, WCE results were considered as either true negative or true positive and sensitivity and specificity were calculated according to both assumptions. RESULTS: Recurrence occurred in 21 patients (68%) and was detected by ileocolonoscopy in 19 patients. Sensitivity was 90% and specificity 100%. Sensitivity of WCE was 62% and 76% and specificity was 100% and 90%, respectively, depending on assumptions. There was a correlation between the severity of the lesions measured by both methods (p<0.05). Lesions located outside the scope of conventional endoscopy were detected by WCE in two thirds of patients with excellent interobserver agreement (kappa>0.9) for all lesions with the exception of ulceration (kappa=0.7). CONCLUSIONS: The sensitivity of WCE in detecting recurrence in the neoterminal ileum was inferior to that of ileocolonoscopy. In contrast, WCE detected lesions outside the scope of ileocolonoscopy in more than two thirds of patients. Additional follow up studies are needed to assess the clinical relevance of such lesions. At the present time, it seems that WCE cannot systematically replace ileocolonoscopy in the regular management of patients after surgery.

[Endoscopic therapy for pancreatitis in children].

Authors report on 3 cases of children treated by therapeutic endoscopic retrograde cholangiopancreatography for pancreatitis (ERCP). The first child presented with familial pancreatitis: he was treated by sphincterotomy and lithiasis extraction. The second child presented with pancreatitis secondary to pancreas divisum: she was treated by sphincterotomy and stunt of small caroncula. The third child presented with severe pancreatitis with pseudocyst: after drainage she was treated by sphincterotomy, Wirsung dilatation and lithiasis extraction. ERCP is a beneficial treatment and may be alternative to surgery in complicated pancreatitis.

Low rectal volumes in patients suffering from fecal incontinence: what does it mean?

BACKGROUND: Rectal perception and adaptation to distension are widely heterogeneous in subjects with faecal incontinence. AIM: To quantify rectal physiology in patients with incontinence and low maximum rectal volume, according to AGA guidelines on anorectal testing techniques. PATIENTS AND METHODS: 148 patients (12 men, 136 female) with incontinence to liquid and/or solid stools were investigated. Distending isobaric procedures were carried out using an electronic barostat in order to analyse perception and adaptation of the rectum. RESULTS: Pain during isovolumic rectal distension at a level of 100 mL or less was experienced in 21 subjects (14.2%). As defined by isobaric distensions, incontinent patients with low MTV had more frequently a hypocompliant rectum (62%) when compared with those with higher MTV (31%, P = 0.046). Perception scores tended to be higher at each step of distending rectal pressure: incontinent patients with low MTV had more frequently a hypersensitive rectum (48%) when compared with those with normal or high MTV (24%, P = 0.035). Only four of 21 incontinent subjects with low MTV had an isolated hypersensitive rectum. CONCLUSION: Both sensitivity and compliance are altered in patients with low MTV. A more extensive study of the role of sensory and compliance aspects of subjects with incontinence is warranted.

Routine management of gastro-oesophageal reflux disease by gastroenterologists in France: a prospective observational study.

AIMS: To obtain data on routine care of gastro-oesophageal reflux disease by French gastroenterologists. PATIENTS: Five thousand and forty-five adults with gastro-oesophageal reflux disease. METHODS: Patients were recruited by a representative sample of 598 French gastroenterologists. A full disease history, with treatments given/investigations undertaken, was obtained from all patients. The patients' expectations with regard to the improvement of the symptoms' control and the corresponding assessments made by the gastroenterologists were recorded on a 4-point scale. RESULTS: The mean time since diagnosis was approximately 4 years. The most commonly presented symptom was heartburn (79% of patients). A total of 3735 patients (74%) underwent endoscopy because of gastro-oesophageal reflux disease. Erosive oesophagitis was present in 38% and Barrett's oesophagus in 8%. Medical therapy for gastro-oesophageal reflux disease was prescribed in 92% of patients, of whom 86% received proton pump inhibitors. Lifestyle advice was given to 73% of patients. Overall, 84% of patients and 72% of physicians expected 'highly' or 'moderately' improved control of gastro-oesophageal reflux disease. Gastroenterologists underrated the need for improvement of the symptoms' control as expressed by 'de novo' as well as 'previously diagnosed' patients. CONCLUSIONS: This study provides cross-sectional data on the management of gastro-oesophageal reflux disease by gastroenterologists in France. Most patients have high expectations of an improvement in their management, but gastroenterologists generally underrate these expectations.

Frequency and significance of granulomas in a cohort of incident cases of Crohn's disease.

BACKGROUND AND AIMS: Epithelioid granulomas is one of the best histological criterion for distinguishing Crohn's disease (CD) from other inflammatory bowel diseases. Few data are available on the time of occurrence of epithelioid granulomas, and the value of epithelioid granulomas in predicting outcome has been determined only in cohorts of prevalent CD cases. Our objective was to evaluate epithelioid granuloma occurrence in incident CD cases and to examine the associations between epithelioid granulomas and outcome. PATIENTS AND METHODS: We reviewed the histological reports of endoscopic and surgical specimens in a cohort of 188 consecutive incident CD cases seen in 1994 and 1995, and recorded the occurrence of epithelioid granulomas, isolated giant cells, and microgranulomas. Kaplan-Meier curves were plotted for time from CD diagnosis to immunosuppressive treatment or surgery, and associations between epithelioid granulomas and outcome were evaluated in a multivariate analysis. Follow up was at least five years. RESULTS: Granulomas were found in 69 (37%) patients, including 46 (25%) at presentation. Median time from CD diagnosis to epithelioid granuloma detection was 0.16 (0-63) months overall, and 9.59 (0.1-63) months in 23 patients who became epithelioid granuloma positive during follow up. Isolated giant cells were found in 6% of patients and microgranulomas in 12%. Epithelioid granuloma detection increased with the number of endoscopic sampling procedures; sampling site had no influence. By multivariate analysis, epithelioid granulomas were associated with surgical resection but not immunosuppressive therapy. CONCLUSIONS: Epithelioid granulomas may separate CD into two pathological subsets and may indicate aggressive disease.

A new mutation of E-cadherin gene in familial gastric linitis plastica cancer with extra-digestive dissemination.

Over a 12-month period, we diagnosed poorly differentiated infiltrative independent-cell gastric adenocarcinoma in two brothers and one sister aged 41 to 47 years. Their father had died from antral cancer at the age of 34 years. These cancers had two characteristic clinical features: rapid course and distant malignant dissemination. In all three patients, polymerase chain reaction-sequencing of the E-cadherin (CDH1) gene of white blood cells identified a heterozygous nonsense mutation of exon 3, producing a stop codon at position 95 (Q95X), resulting in a truncated protein. The alteration of this protein, which plays a crucial role in epithelial cell adhesion, probably explains the clinical expression in this type of familial diffuse gastric cancer.

[Crohn's disease complicated by multiple and recurrent aseptic splenic abscesses].

We report a case of multiple aseptic splenic abscesses occurring in a woman with Crohn's disease for three years. All microbiological samples were negative. The diagnosis was suspected on abdominal echography and CT scan and confirmed on histologic examination of the splenectomy specimen. The evolution was marked by recurrence of fever and inflammatory syndrome, associated to transitory morphological abnormalities of the accessory spleen. Aseptic splenic abscesses recurrence was suspected. This case allows us to consider aseptic splenic abscesses as an extra-intestinal manifestation and not as a splenic localisation of Crohn's disease.

[Incidence of inflammatory bowel disease in children in Brittany (1994-1997). Breton association of study and research on digestive system diseases (Abermad)].

BACKGROUND: The aim of this work was to determine in Brittany the incidence and main clinical pattern of inflammatory bowel disease (IBD) occurring during childhood. These data are compared to the previous epidemiologic data available from the Northern France registry or around the world. METHODS: Private and public Brittany gastroenterologists (2,836,418 inhabitants including 618,049 children under 17 years of age) referred all patients consulting for inflammatory bowel disease from January 1994 to December 1997. An interviewer-practitioner completed at the gastroenterologist's office a standard questionnaire for each patient. Each case was independently reviewed by four experts in a blind manner and made a final diagnosis of Crohn's disease (CD), ulcerative colitis (UC), or ulcerative proctitis and acute colitis (onset of symptoms < 6 weeks) or unclassified chronic colitis. RESULTS: Among 1,309 cases recorded, 88 were under 17 years of age (6.7%): 43 (49%) had CD (including three possible cases), 14 (16%) had UC (including three proctitis), 24 (27%) acute colitis and 7 (8%) unclassified chronic colitis. The crude mean annual incidence (per 100,000 children) based on definite and probable cases only was 2.5 for IBD, 1.6 for CD and 0.57 for UC, without variation between 1994 and 1997. The male/female ratio was 2.3 for CD and 1.3 for UC. The mean time between onset of disease and diagnosis was equal to 7.2 and 8.6 months for CD and UC respectively (median: 3 and 5 months). A familial history of IBD was present in 5 cases (8%). In CD, the small and large bowel were involved in 58% of patients, whereas an isolated involvement of small or large bowel occurred in 15% and 23% of cases. Among the 14 UC, there were three proctitis and four pancolitis. Among 43 CD, a granuloma was present in 48% of cases. CONCLUSIONS: In Brittany the incidence of CD and UC in childhood was similar to the published data from Northern France. Clinical presentation and symptoms were not different. However, the rate of acute colitis was higher and the accurate incidence of IBD could be underestimated, requiring a follow-up to classify these cases.

Low sensitivity of invasive tests for the detection of Helicobacter pylori infection in patients with bleeding ulcer.

BACKGROUND: A high false negative rate for antral infection with Helicobacter pylori when assessed by rapid urease test has recently been reported in patients with bleeding ulcer. This result could partly explain the differing prevalence of H. pylori infection in bleeding and non-bleeding ulcers. AIMS: To evaluate the accuracy of a rapid urease test (UT), histology and culture for detection of H. pylori in antral biopsies from acute bleeding peptic ulcer patients using a serological test as reference. PATIENTS AND METHODS: All consecutive patients with active bleeding gastric or duodenal ulcer at endoscopic examination admitted in six university hospitals in France were considered for inclusion. Five antral biopsies were taken during the diagnostic endoscopy for UT, culture and histology. A blood sample was taken for H. pylori serology. RESULTS: One hundred and eighty one patients were included and 129 (71%) had a positive serology. The sensitivity of UT, histology and culture for detection of H. pylori infection were 41%, 33% and 34%, respectively. The sensitivity and specificity of the combination of the three invasive tests were 48.8% (95% CI: 40.2-57.4) and 90.6% (95% CI: 82. 6-99) respectively. In the 52 serologically negative patients, only 5 had at least one invasive positive test. The sensitivity of the invasive tests decreased significantly with age but was not influenced by NSAIDs intake. Of 80 patients with a positive serological test and negative histological evaluation for H. pylori, chronic antral inflammation was found in 70 patients (87%). In 46 patients with both negative serological test and H. pylori negative test according to histology, only 13 (28%) had chronic antral inflammation. CONCLUSIONS: The sensitivity of invasive tests for detection of H. pylori is low during acute ulcer bleeding, and they should be used with caution in this condition. A serological test is recommended to identify patients with H. pylori infection in spite of negative invasive tests.

[Multicenter prospective study of prognostic factors of gastroduodenal ulcer hemorrhages. Reevaluation of clinical and endoscopic factors in the era of endoscopic hemostasis].

AIM: To evaluate in a prospective study the prognostic factors of recurrent bleeding and mortality in patients presenting with high risk peptic ulcer bleeding routinely treated by endoscopic hemostasis. PATIENTS AND METHODS: A multicenter study was carried out in 8 Western French hospitals in 144 patients with gastrointestinal bleeding peptic from ulcer type I or IIa, b as defined by Forrest classification. Thirty four and 38 parameters were studied respectively in order to predict recurrent bleeding and death. Significant predictive factors (P < 0.1) in univariate analysis were entered in a multivariate logistic regression analysis. RESULTS: Endoscopic hemostasis was performed in 108 of 144 cases (75%). Recurrent bleeding and death occurred in 39 (28%) and 22 cases (15%), respectively. By multivariate analysis, the only predictor of rebleeding was hypovolemia at admission. Predictors of death were ASA score, cardiovascular Goldman score and recurrent bleeding. In this study, prevalence of Helicobacter pylori infection was low (41%) but was not a predictive factor. CONCLUSIONS: In a selected population of peptic ulcer bleeding patients with high risk of rebleeding, prevalence of recurrent bleeding and death remains rather high, despite routine endoscopic hemostasis. In the era of endoscopic hemostasis, clinical parameters remain the best prognostic factors of peptic ulcer bleeding outcome.
