Differential diagnosis of inflammatory bowel disease. A comparison of various diagnostic classifications.

Fifty consecutive patients with inflammatory bowel disease of the colon who presented at the University Hospital Rotterdam/Dijkzigt were assessed by four methods: clinical diagnosis, criteria defined by Lennard-Jones and by the Organisation Mondiale de Gastroenterologie (O.M.G.E.) scoring systems, and histologic slide review. All cases were classified into three diagnostic groups: established Crohn's disease (CD), indeterminate colitis, or definite ulcerative colitis (UC). The classifications were compared by kappa analysis. Eighteen of the 50 patients were classified as having established CD by the O.M.G.E. scoring system and Lennard-Jones criteria; 17 were so classified by clinicians, and only 8 by histologic slide review. The agreement among clinician's diagnosis, Lennard-Jones criteria, and the O.M.G.E. scoring system was good (Fleiss-Cohen-weighted kappa; p less than 0.001). Agreement among histology, Lennard-Jones criteria, and the O.M.G.E scoring system was less good (p less than 0.05) and not significantly associated with clinical diagnosis. Histology was less prone to diagnose established CD or established UC and more likely to diagnose indeterminate colitis. This study has shown that the systems of disease definition set out by Lennard-Jones and the O.M.G.E. are comparable and agree well with each other and clinicians's diagnosis, but biopsy specimens have a limited diagnostic value in disease differentiation in inflammatory bowel disease.

Patient's assessment of an information booklet on Crohn's disease written by a patient.

Patients with Crohn's disease want information about the condition. "So you've got Crohn's disease", an information booklet written by a patient was sent to patients for evaluation. Most found it useful, particularly in the practical advice, and suitable for all patients with Crohn's disease. Patients can be a valuable source of information for other patients and doctors. They should be encouraged to share their experiences.

The role of educational videos in gastroenterology.

The potential role for video tape education in gastroenterology is discussed. The need for material to inform patients about their diagnoses is widely acknowledged and educators need to take advantage of modern techniques. Studies in general practice, diabetes care, and asthma care have found that videos have significant benefits when compared with conventional techniques. There are few such video tapes available to gastroenterologists. It has been shown that patients are keen to accept educational material in this form provided it is shown at a suitable time and in a suitable venue.

Elderly ileostomists and their social problems.

There is no clear definition of who is "elderly." For the purpose of this review, we studied ileostomists over the age of 60. Fifty of 55 such members of the Ileostomy Association completed a questionnaire about problems they had experienced. The mean age of the respondents was 68.5 +/- 5.5 years, and they had had an ileostomy for 14.6 +/- 10.2 years. Only 68% of patients felt that they had received a full explanation before surgery. Family members and the Ileostomy Association had been most effective in support of the ileostomist; stoma therapists less so. Thirty-two percent of patients were shocked or repelled by their stoma immediately after surgery, and 54% had problems touching or cleaning it, although their difficulties diminished with time. The majority of patients were unaffected in their social activities by surgery, although 18% gained confidence and 12% lost it. These problems were unaffected by age at operation.

Inflammatory bowel disease in the rural Indian subcontinent: a survey of patients attending mission hospitals.

39 missionaries working at 38 separate mission hospitals or clinics in Bangladesh. India, Nepal and Pakistan completed questionnaires about their clinical practice during the previous year, 1980. Data were collected about gastrointestinal disorders, including coeliac disease, tropical sprue, bloody diarrhoea, amoebiasis, typhoid, cholera, inflammatory bowel disease and diverticular disease. More than 386,000 out-patients and over 56,000 in-patients were treated with an estimated 12,272 cases of bloody diarrhoea, 7,310 of amoebiasis, 2,113 of typhoid and 872 cases of intestinal tuberculosis, 74 cases of inflammatory bowel disease were diagnosed, of which 56 were ulcerative colitis and the remainder were said to have Crohn's disease. Surgery was performed in 28 hospitals, but only 10 (26%) had a histology service. Inflammatory bowel disease appears to be a relatively more common cause of diarrhoea in the Indian subcontinent than in sub-Saharan Africa (z = 5.47, p less than 0.001). The proportion of patients with bloody diarrhoea who have ulcerative colitis Crohn's disease was similar throughout the region. The rate of cases having ulcerative colitis rather than Crohn's disease was greater in India (z = 3.1, p less than 0.005), and in Bangladesh (z = 3.2, p less than 0.005), than in Pakistan (z = 1.28, NS) or Nepal and Bhutan (z = 0, NS). The relative risk of Indians developing ulcerative colitis rather than Crohn's disease is 2.6 (95% confidence limits 1.4-4.8, NS). This may reflect diagnostic difficulties in distinguishing Crohn's disease from intestinal tuberculosis, but it may also shed light on similar differences now being reported in migrant groups in Western Europe.

Epidemiological survey of coeliac disease and inflammatory bowel disease in first-degree relatives of coeliac patients.

One hundred and sixty-two of 182 patients with coeliac disease provided satisfactory details of family size and the prevalence of coeliac disease and inflammatory bowel disease among their first-degree relatives. Patients ranged in age from 11 months to 79 years with a mean age of 41 (+/- 23) years. Twenty patients had at least one first-degree relative with coeliac disease: a total of 25 of 861 relatives were affected (prevalence = 2904/100,000) compared with an expected 0.9 cases (prevalence = 100/100,000; p less than 0.001). Six relatives had inflammatory bowel disease (prevalence = 697/100,000) compared with an expected 1.3 cases (prevalence = 150/100,000; p less than 0.001). Five of these had ulcerative colitis, and one had Crohn's disease. The relative risk of ulcerative colitis is, therefore, five times greater for first-degree relatives of people with coeliac disease than for the general population (95 per cent confidence interval, 4.7-7.2). There is a clear association between coeliac disease and ulcerative colitis, which may point to factors involved in the aetiology of colitis.

Small bowel biopsy for disaccharidase levels: evidence that endoscopic forceps biopsy can replace the Crosby capsule.

Lactase, sucrase and maltase activities in endoscopic biopsies from the second part of the duodenum were compared to those in Crosby capsule biopsies from the proximal jejunum. In patients with villous atrophy disaccharidase activities were reduced compared with histologically normal mucosa in the duodenum and jejunum. Disaccharidase activities were significantly lower in the duodenum than in the proximal jejunum of patients with histologically normal mucosa and in those with partial villous atrophy but not significantly different for total villous atrophy patients. Primary and secondary disaccharidase deficiencies can be identified in biopsies from the duodenum. Duodenal biopsy is a valid alternative to jejunal biopsy for the diagnosis of disaccharidase deficiency.

Epidemiological study of asymptomatic inflammatory bowel disease: the identification of cases during a screening programme for colorectal cancer.

An asymptomatic population of 37,000 people in the Nottingham area were offered faecal occult blood tests in a screening study for colorectal cancer. Seventeen thousand nine hundred and thirty people completed the tests and 481 individuals with positive tests underwent full investigation of the colon. Eight people with previously undiagnosed inflammatory bowel disease were identified. In five cases there was total ulcerative colitis; in one a proctitis and in two Crohn's disease. Two further patients with ulcerative colitis were identified; they had been lost to follow up for 25 and 45 years respectively. The combined prevalence of inflammatory bowel disease was 56/10(5) and it is likely that current studies of the epidemiology of these conditions may underestimate the true prevalence by between 27% and 38%.

Crohn's disease: risk of recurrence and reoperation in a defined population.

Two hundred and ten patients with Crohn's disease (CD) were identified in an epidemiological survey of inflammatory bowel disease in the Leiden Health Care Region of the Netherlands. The survey included all patients with CD seen between 1979-1983. The duration of disease ranged from less than one year to 48 years. Of the 210 patients with CD, 118 (56%) underwent surgical resection. Sixty one had an ileocaecal resection, 14 a proctocolectomy, in seven cases as a two stage procedure; 12 a segmental colectomy with end-to-end anastomosis and eight a subtotal colectomy with ileostomy. Twenty-one of these 118 patients (18%) had recurrences requiring reoperation; in 11 because of recurrence at the anastomotic site. Life table analysis showed that after 10 years 17% of patients required further resection for recurrence and 8% for relapse. By 20 years the rate of recurrence had risen to 56%. Patients over the age of 30 at first resection were at 1.5 fold greater risk of requiring further surgery than younger patients. The initial site of disease played no role in recurrence and there was no evidence that preoperative disease duration, delay in diagnosis, or late surgery had any effect on recurrence rates. This is one of the few community based studies to measure recurrence and relapse. A balanced appraisal is that surgery is not permanently curative, but the need for further resection may be lower than previously suggested.
