Validation study of automatically generated codes in colonoscopy using the endoscopic report system Endobase.

OBJECTIVE: Gastrointestinal endoscopy databases are important for surveillance, epidemiology, quality control and research. A good quality of automatically generated databases to enable drawing justified conclusions based on the data is of key importance. The aim of this study is to validate the correctness of coding of a national automatically generated anonymous endoscopy database. MATERIAL AND METHODS: We evaluated a total of 500 colonoscopies performed in five larger hospitals of the TRANS.IT project focusing on endoscopy reporting. Randomly 500 examinations were selected from a total of 5,000 examinations and their generated endoscopic terminology codes as well as complete reports were analysed. Indications for the examination and described findings were scored for correctness and clinical relevance of the coding that would be exported to the anonymous database. RESULTS: Indications were correctly coded in 92% of all examinations (range 76-100%) per hospital. Correct coding of findings ranged from 42% to 93% per hospital (mean 77%). Different correct coding proportions were seen varying with the diagnosis, with the highest correct coding rates in polyps, carcinoma and diverticular disease. Incorrect coded examinations were scored for clinical relevance. Overall 11% of the investigated examinations were incorrectly coded with clinical relevance. CONCLUSIONS: Accuracy of clinically relevant endoscopy data recorded in the TRANS.IT anonymous central database is high. Further improvement is desirable, which may be achieved by education of individual endoscopists and enhancement of the program.

Gastrointestinal endoscopic terminology coding (GET-C): a WHO-approved extension of the ICD-10.

Technological developments have greatly promoted interest in the use of computer systems for recording findings and images at endoscopy and creating databases. The aim of this study was to develop a comprehensive WHO-approved code system for gastrointestinal endoscopic terminology. The International Classification of Diseases, 10th edition (ICD-10), and the ICD-10 clinical modification (ICD-10-CM) were expanded to allow description of every possible gastrointestinal endoscopic term under conditions defined by the WHO. Classifications of specific gastrointestinal disorders and endoscopic locations were added. A new chapter was developed for frequently used terminology that could not be classified in the existing ICD-10, such as descriptions of therapeutic procedures. The new extended code system was named Gastrointestinal Endoscopic Terminology Coding (GET-C). The GET-C is a complete ICD-10-related code system that can be used within every endoscopic database program for all specific endoscopic terms. The GET-C is available for free at http://www.trans-it.org/.

Effects of regular physical activity on defecation pattern in middle-aged patients complaining of chronic constipation.

OBJECTIVE: It is not well known whether physical activity (PA) is useful in the management of patients complaining of constipation. The aim of this study was to test the influence of regular PA on colonic transit time and defecation in middle-aged inactive patients suffering from chronic idiopathic constipation. MATERIAL AND METHODS: Forty-three subjects (> 45 years) were randomly divided into group A (n = 18, 16 F, 2 M) and group B (n = 25, 20 F, 5 M). Group A subjects maintained their normal lifestyle during 12 weeks, followed by a 12-week PA programme. Group B performed a 12-week PA programme after randomization. PA comprised 30 min of brisk walking and a daily 11-min home-based programme. Both groups received dietary advice. Colonic transit time was measured using a radiographic multiple marker single film technique. RESULTS: Despite dietary advice, mean fibre and fluid intake did not change. In group B a significant reduction in 3 out of 4 of the Rome I criteria for constipation was observed, i.e. percentage of incomplete defecations, percentage of defecations requiring straining and percentage of hard stools (p < 0.05). As a consequence, the number of fulfilled Rome criteria for constipation decreased (2.7 to 1.7; p < 0.05). Furthermore, the rectosigmoid and total colonic transit time decreased (17.5 to 9.6 h and 79.2 to 58.4 h, respectively; p < 0.05). After PA the number of fulfilled Rome criteria also decreased in group A (2.6 to 1.7; p < 0.05). CONCLUSIONS: In middle-aged inactive subjects with symptoms of chronic constipation, it is advisable to promote regular physical activity since it improves both the defecation pattern and rectosigmoid or total colonic transit time.

IBS-like symptoms in patients with inflammatory bowel disease in remission; relationships with quality of life and coping behavior.

The aim of this study was to assess the prevalence of irritable bowel syndrome-like symptoms in healthy controls and inflammatory bowel disease patients in remission using the Rome II criteria. Furthermore, the possible relation of irritable bowel syndrome-like symptoms with the quality of life and coping behavior was studied. Seventy-three ulcerative colitis patients in remission, 34 Crohn's disease patients in remission, and 66 healthy controls completed questionnaires on irritable bowel syndrome, quality of life, and coping. Using the Rome II criteria, irritable bowel syndrome-like symptoms were found in one-third of ulcerative colitis patients and in 42% of Crohn's disease patients in remission. The presence of irritable bowel syndrome-like symptoms impaired the quality of life of patients, while no relation was found between the presence of symptoms and coping strategies.

High prevalence of fatigue in quiescent inflammatory bowel disease is not related to adrenocortical insufficiency.

OBJECTIVES: Inflammatory bowel disease (IBD) patients, with active as well as quiescent disease, frequently complain of fatigue. This often has consequences for patients' work and daily lives. The primary aim of this study was to assess the prevalence and severity of fatigue in IBD patients in remission. Furthermore, we studied the correlation between fatigue and disease activity, quality of life, and biochemical and hematological test results, and the role of (secondary) hypocortisolism. METHODS: Eighty subjects with proven IBD were included. Disease activity was assessed using the Clinical Activity Index for Ulcerative Colitis and the Crohn's Disease Activity Index. Quality of life was measured by the Inflammatory Bowel Disease Questionnaire, and fatigue was assessed using the Multidimensional Fatigue Inventory (MFI). Routine biochemical and hematological tests were performed, and basal cortisol was determined. To evaluate adrenocortical reserve in subjects with a cortisol level of <0.4 micromol/L, a low dose adrenocorticotrophin hormone test was performed. Healthy age- and sex-matched subjects (n = 67) served as controls. RESULTS: More than 40% of the IBD patients in remission suffered from fatigue. Mean MFI scores of the IBD patients were comparable to mean MFI scores reported in cancer patients. The Inflammatory Bowel Disease Questionnaire showed a negative correlation with the MFI (r = -0.735; p < 0.001). No correlation was found between fatigue and basal cortisol levels or other laboratory parameters. CONCLUSION: Fatigue is an important feature in IBD in remission, adversely affecting the quality of life. It does not, however, affect all patients, nor does it seem to be the result of hypocortisolism.

Benign recurrent intrahepatic cholestasis progressing to progressive familial intrahepatic cholestasis: low GGT cholestasis is a clinical continuum.

Benign recurrent intrahepatic cholestasis (BRIC) is an autosomal recessive liver disease, characterised by intermittent attacks of cholestasis, which can start at any age and last for several weeks to months. Characteristically serum GGT activity is low and normal liver structure is preserved. Progressive familial intrahepatic cholestasis (PFIC) is another liver disease, characterised by severe cholestasis, starting almost invariably before 6 months of age. All patients progress to cirrhosis, liver failure and death, unless a liver transplantation is performed. We now identified four patients who presented in childhood with recurrent attacks of cholestasis, while in the course of the disease the cholestasis gradually became permanent. Although liver biopsies performed in the early stages of the disease showed normal liver architecture, late stage biopsies revealed evident fibrosis with porto-portal septa formation. In conclusion, the disease of these patients started with the clinical and histopathological characteristics of BRIC but progressed to PFIC.
