We assessed the nutritional status of 119 patients with chronic gastrointestinal symptoms due to organic disorders (inflammatory bowel disease, IBD; peptic ulcer, PU; malabsorption syndrome, M; and malignant gastrointestinal tumours, T), by standard anthropometry and marker proteins (albumin; retinol-binding protein, RBP; and thyroxine-binding prealbumin, TBPA). We also studied 31 patients with irritable bowel syndrome (IBS) and 75 age-matched healthy controls (C). Compared with healthy controls, patients with organic bowel disease had significant abnormality of two or more anthropometric measurements (P less than 0.05). Plasma albumin was reduced in patients with IBD, M and T (P less than 0.001), but RBP and TBPA measurements were lower in all patient categories (P less than 0.01) including IBS. Stepwise discriminant analysis of the patient data alone, using three to six parameters, correctly separated 65 per cent PU patients, 66 per cent IBD and M, 72 per cent IBS and 88 per cent patients with T from other disease categories. We conclude that patients with chronic gastrointestinal symptoms often have some nutritional disturbances and that simple anthropometric and protein measurements might help us to distinguish patients with functional bowel disease from those with organic bowel disease.

A hydrocortisone suspension enema was radiolabeled with [99mTc]technetium sulfur colloid and administered to four normal subjects and eight patients with varying degrees of inflammatory bowel disease. The extent of enema spreading was monitored using external scintigraphy for a period of up to 4 hr after administration. Pretreatment of normal subjects with an evacuation enema resulted in spreading of the radiolabeled enema throughout the entire colon. In seven of the eight patients studied, the enema migrated a distance equal to or greater than the extent of disease involvement. An in vivo stability study with an indium-111-labeled enema, using the perturbed angular correlation technique, revealed that the enema retains its stability for up to 90 min after administration. These results indicate that the use of hydrocortisone enemas may not be restricted to distal bowel disease, but may also be effective in inflammatory bowel diseases involving proximal regions of the colon.

To better characterize Crohn's disease in the elderly, 24 patients ranging in age from 64 to 85 years were reviewed and compared with a younger group (20 to 61 years of age) matched for sex and duration of disease. Forty-one variables encompassing clinical, laboratory, and radiologic data and medical and surgical aspects of treatment were analyzed. The older group was characterized by a longer delay in diagnosis, more hematochezia, and a higher incidence of diverticular and cardiovascular disease. Elderly patients had less pain, less often a palpable abdominal mass, less small-bowel disease, less drug treatment, and no family history of inflammatory bowel disease. Otherwise, the disease in the two groups had similar manifestations, and no discriminating features to enable easy diagnosis in the elderly were found. Crohn's disease must be considered when evaluating older patients with diarrhea, abdominal pain, weight loss, and bleeding.

We present two patients with biopsy proven primary intestinal lymphangiectasia in whom CT demonstrated diffuse nodular thickening of small bowel without adenopathy or hepatosplenomegaly. One patient had extensive ascites. Although the CT findings are not specific to lymphangiectasia, they may allow one to suggest the diagnosis in the patient with protein losing enteropathy and help distinguish it from inflammatory bowel disease, lymphoma, celiac disease, or Whipple disease.

Evidence for autoimmunity in diarrhoeal disease is reviewed. Firstly, coeliac disease (CD) is considered. The incidence of tissue-reactive autoantibodies in both adults and children with CD (68% and 65%, respectively) is higher than the incidence of these autoantibodies in controls (6% in normal adults, and 14% and 9% in disease controls drawn respectively from adult and child populations). The R1 antireticulin antibody, when present, was found to disappear after several weeks on a gluten-free diet, but in contrast, other autoantibodies persisted. Secondly, a case is argued for a new disease category, namely "autoimmune enteropathy." Seven cases are reviewed in which patients presented with protracted diarrhoea, a small intestinal enteropathy which failed to heal during periods of total parenteral nutrition, and evidence of a predisposition to autoimmunity (namely, the presence of high titre autoantibodies including one specific for gut epithelium, and/or the presence of associated diseases regarded to be autoimmune). Thirdly, evidence for autoimmunity in inflammatory bowel disease is reviewed and includes discussion of serum goblet cell antibodies and of circulating T cells which participate in antibody-dependent cellular cytotoxicity in vitro using colonic epithelial cells as targets. Finally, an unusual child is described who presented with chronic diarrhoea and a flat small intestinal mucosa, who responded to gluten withdrawal but who later relapsed spontaneously during a strict gluten-free diet. Her mucosa healed only after a period of total parenteral nutrition and treatment with oral steroids. This child's enteropathy was also associated with thyrotoxicosis and a microscopic colitis.

The absorption of 75Se-23-selena-25-homotaurocholate (SeHCAT) was compared with vitamin-B12 absorption and conventional radiography in 44 patients with inflammatory bowel disease. The retention of SeHCAT was normal in 11 patients with ulcerative colitis but was abnormally low in 9 patients with terminal-ileal resection, 9 out of 14 patients with small-bowel Crohn's disease and in 2 out of 10 patients with Crohn's colitis. The 5 patients with small-bowel Crohn's disease and normal retention had either inactive disease or no radiological evidence of terminal ileal involvement. Measurements of the absorption of vitamin B12 did not discriminate between these groups, and there was very poor correlation between B12 and SeHCAT absorption (r = 0.506, P less than 0.05). There was extremely good correlation of SeHCAT retention measured using a wholebody counter with that measured using an uncollimated gamma camera (r = 0.96, P less than 0.001). The results suggest that SeHCAT retention may prove complementary to conventional methods of assessing small-bowel disease in patients with inflammatory bowel disease. As measurement by gamma camera is feasible, this test can be used in most departments of nuclear medicine.

The results of fibreendoscopy of the colon are described in 255 consecutive examinations. Of the examinations, 26.5% resulted in a diagnosis being made solely by endoscopy. This included 17 cases of carcinoma, 15 patients with polyps, and 25 patients with inflammatory bowel disease. The most common reason for referral was undiagnosed rectal bleeding (75 cases) and endoscopy alone was successful in diagnosing the probable or definitive source of bleeding in 50% of the cases referred. It is not yet clear, however, to what extent this figure may reflect the inadequacy of conventional radiology.A definitive radiological diagnosis was refuted in 11 patients and an unnecessary laparotomy avoided in seven of these. There is no doubt that fibreoptic colonoscopy increases diagnostic accuracy in large bowel disease and is especially helpful in cases where radiology is either negative or equivocal.

Two pathologists have independently applied 95 separate pathological criteria to 50 cases of inflammatory large bowel disease firmly diagnosed clinically as 25 cases of Crohn's disease and 25 cases of ulcerative colitis. The observer agreement in the recording of each feature has been calculated and correlations have been made between the pathological features and the final agreed diagnosis in order to obtain an estimate of the value of each feature in differential diagnosis. The features which have been found to be most accurately observed and useful in the diagnosis of Crohn's disease include confluent linear ulcers, deep fissures, an aggregated inflammatory pattern, and sarcoid-like granulomata. The features which have been shown to be most accurate and valuable in the diagnosis of ulcerative colitis include a ;healed granular' mucosa, a continuous inflammatory pattern, an irregular gland pattern, and the absence of fissures. The authors consider that the use of such accurate and valuable pathological criteria in the examination of inflammatory bowel disease would facilitate retrospective correlation with the clinical findings and help to clarify those intermediate cases which are at present a source of diagnostic difficulty.

Plasma levels of circulating carcinoembryonic antigen (CEA) were measured by zirconyl phosphate gel radioimmunoassay in 112 patients with chronic inflammatory bowel disease. The levels were then related to category, extent, duration, and severity of disease, as well as to the ages and surgical status of the patients. The distribution of CEA levels and their mean values were significantly raised over the levels in 33 normal control subjects, and were similar among patients with ulcerative colitis compared with those with granulomatous bowel disease. Positive values were defined as those in excess of 2.5 ng/ml. Positive assays occurred in 42% of ulcerative colitis patients, in 38% of Crohn's disease patients, and in 40% of the total group with inflammatory bowel disease. Among normal control subjects, only 3% were positive. Among inflammatory bowel disease patients, positive CEA assays occurred more frequently with more severe disease, more extensive anatomical involvement, younger ages, and shorter duration of disease. Those patients who had undergone total colectomy showed levels of circulating CEA and frequency of CEA positivity similar to those of an age-matched normal control group. Levels of CEA did not correspond with known cancer risk factors in patients with inflammatory bowel disease. Although rising or persisting plasma CEA values unrelated to severity and extent of disease may indicate an unfavourable prognosis in cancer, this study shows that a single CEA value in patients with chronic inflammatory bowel disease is not a reliable indicator of cancer risk.

Fifty-one patients with large bowel disease were examined with the Olympus CF-SB fibreoptic colonoscope. With adequate bowel preparation and employing inhalational analgesia administered by a self-demand valve the whole sigmoid colon could be examined in the majority of patients within 30 minutes. In 23% of cases (12/51) the diagnosis was either made or confirmed by this procedure alone. Fibreoptic sigmoidoscopy is especially helpful in patients with either equivocal or failed barium enemas and is indicated in patients with unexplained rectal bleeding, extending the search for polyps and cancer, and studying patients with inflammatory bowel disease.About one quarter of biopsies taken from a flat mucosal surface with the Olympus flexible biopsy forceps may be insufficient for detailed histology due to their small size. For this reason multiple biopsies may be taken. Adequate biopsies were always obtained from projecting lesions and could be very accurately sited. Colour photography employing automatic exposure control is used to supplement the information obtained. It is concluded that fibreoptic sigmoidoscopy is a valuable additional investigation in selected patients with suspected disease of the large bowel and to date has been without complications.
