In 30 patients with cancer of the large bowel, 24 (80%) had detectable levels of methane in their breath, compared with 25 (39%) of 64 patients with non-malignant large-bowel disease and 83 (40%) of 208 subjects without large-bowel disease. These findings suggest that there may be a difference in anaerobic intestinal flora between patients with cancer of the large bowel and those without the disease. This difference may antedate the development of the tumour or, alternatively, result from the tumour.

Granulomata occur in the liver not only in patients with systemic granulomatous disease, but also in a variable number with underlying liver disease and in a heterogeneous group of disorders that appear to be neither hepatic nor granulomatous in nature. The hepatic granulomata found in association with liver disease are rarely attributable to complicating systemic granulomatous disease, and probably represent a nonspecific response to the underlying hepatic disease. In the heterogeneous group of diseases that appear to be neither hepatic nor granulomatous in nature, hepatic granulomata may (in some instances) represent a nonspecific response to such conditions as intraabdominal malignancy and ulcerative bowel disease. However, in others, particularly those with unexplained prolonged fever, hepatic granulomata may be attributable to specific agents that are overlooked or escape detection by currently available diagnostic measures. The etiology of hepatic granulomata can seldom be established on histological grounds alone, and usually requires collateral clinical and laboratory evidence for identification.

The clinical courses of 53 adult patients with the short bowel syndrome (SBS) were evaluated to determine the incidence of and indications for reoperation. Mesenteric vascular disease (23 patients) and malignancy/irradiation (18 patients) were the most frequent causes of resection. Early reoperation was necessary in nine (17%) patients, primarily for intestinal complications. Twenty (53%) of the 38 patients leaving the hospital required a later abdominal procedure during the mean follow-up of 30 months (range: 2 to 108 months). Three (33%) of nine patients with ulcer disease had gastric resection. Six (21%) of 28 patients at risk for cholelithiasis developed symptoms. Four of these patients underwent cholecystectomy, and three others had a prophylactic cholecystectomy. Ten patients underwent ostomy closure or formation. Intestinal disease necessitated stricturoplasty (three), serosal patch (one), minimal resection (three), or takedown of an ileal conduit (one). Twenty-four (63%) of 38 patients with SBS received home total parenteral nutrition for a mean of 22 months (range: 2 to 105 months). Eleven patients required more than 1 vascular access procedure, and 4 had more than 3 procedures. Patients with the SBS frequently require reoperation for intestinal conditions, cholelithiasis, peptic ulceration, and vascular access. Prophylactic cholecystectomy and strategies for preserving intestinal length are important considerations in these patients.

Suspected risk factors for adenocarcinoma of the small bowel in Crohn's disease include surgically excluded small bowel loops, chronic fistulous disease, and male sex. Review of all seven University of Chicago cases failed to confirm any suspected risk factor. A case-control study was performed to identify possible alternatives. Each case was matched to four randomly selected controls from an inflammatory bowel disease registry matched for year of birth, sex, and confirmed small bowel Crohn's disease. Three factors were significantly associated with the development of cancer: (1) Four cancers developed in the jejunum, and jejunal Crohn's disease was associated with the development of cancer [odds ratio (OR) 8.0, 95% confidence interval (CI) 1.6-39.3]. (2) There was an association between the development of cancer and occupations known to be associated with an increased colorectal cancer risk (OR 20.3, CI 2.7-150.5). Three cases (a chemist with exposure to halogenated aromatic compounds and aliphatic amines, a pipefitter with exposure to asbestos, and a machinist with exposures to cutting oils, solvents, and abrasives) and one of 28 controls (a fireman with multiple hazardous exposures) had an occupational risk factor. (3) Among medications taken for at least six months, only 6-mercaptopurine use was associated with cancer (OR 10.8, CI 1.1-108.7). In conclusion, proximal small bowel disease, 6-mercaptopurine use, and hazardous occupations are associated with cancer of the small bowel in patients with Crohn's disease and can be added to the list of suspected risk factors.

The coeliac disease (CD) or gluten-sensitive enteropathy (GSE) is a permanent intolerance to wheat gliadin and to correlated proteins inducing malabsorption and typical damages of the jejunal mucosa (total or subtotal villous atrophy = SVA) in genetically-predisposed individuals ("DQW2"). A large amount of research has been devoted to CD pathogenesis: the most recent studies, thanks to sophisticated and experimental methods, support the pathogenetic immunological theory and the one of direct cytotoxicity. The correct diagnostic procedure for CD, established in 1970 by the European Society for Pediatric Gastroenterology and Nutrition (ESPGAN), suggested three small bowel mucosal biopsies. In the last years, because of the difficulties of such a practice, the necessity of non-invasive diagnostic approaches has developed; such approaches have been verified in absorption tests (one-hour blood xylose, intestinal permeability methods) and in immunogenetic tests (antibodies antigliadin, anti-reticulin, anti-endomysium, anti 90 KD glycoprotein, anti-human jejunum, HLA I/II antigens). The specific MHC antigens establish CD's incidence in several population and in particular situations, as in first-degree relatives and in diseases associated with CD (dermatitis herpetiformis (DH), insulin dependent diabetes mellitus (IDDM) and other auto-immune syndromes). The specific serum antibodies singly used as first level screening if estimated in combination with absorption tests, reach the highest levels of specificity and sensibility in CD diagnosis. It's anyway fundamental the comparison with at least a typical CD histological feature, caused by a challenge with a sufficient gluten to be carried in dubious cases and in non high auxological risk age (ESPGAN 1989). Adolescence is a period of frequent non compliance with a gluten-free diet and of particular psychological and physical problems: the apparent "gluten insensitivity", typical of teen-agers and adults, recalls the definitions of silent CD and latent CD (iceberg like). In the first case the jejunal mucosa is abnormal and the symptomatology isn't evident. In latent CD, genetically restricted, the mucosa is normal but there are minimal markers of inappropriate immunity to gliadin (at intestinal humoral immunity level) and a possible worsening of histological lesions to the third stage under environmental stimuli. This represents a two-stage model CD. That's why CD is still under-evaluated despite recent statistics reporting an increasing incidence (late and atypical forms). Prevalence rates between 1:300 and 1:4,000 and more are quoted in literature. The necessity of a strict gluten-free diet is confirmed by the evident frequency of lymphoma and by the increased risk of malignancy in untreated CD.(ABSTRACT TRUNCATED AT 400 WORDS)

Pyogenic abscesses of the liver occur in association with a variety of diseases. Sometimes they are caused by anaerobic infections of liver metastases. Uncommonly, however, multiple hepatic abscesses caused by anaerobic bacteria are the presenting signs of unsuspected colonic cancer in the absence of liver metastases. We report a 60-year-old man who presented with febrile cholestatic liver disease initially thought to be metastases. Repeated ultrasound-directed liver biopsies yielded a diagnosis of multiple abscesses. Bacteroides fragilis was grown from the liver specimen and the patient responded well to metronidazole treatment. Two months later, however, overt symptoms of large bowel disease led to the diagnosis of colonic adenocarcinoma. After a 6-month postoperative follow-up, the patient is free of liver metastases. Anaerobic liver abscesses should always alert the clinician to possible silent colonic cancer.

Three patients with extranodal peripheral T-cell lymphoma and a distinctive clinical presentation are described. They had acute onset of fever, weight loss, progressive liver failure, bleeding diathesis, pancytopenia, and myelodysplastic changes in the bone marrow. Each patient had one or more paraneoplastic complications: severe rhabdomyolysis with myoglobinuria and secondary renal failure, cutaneous vasculitis, gluten-sensitive enteropathy, polyserositis, and increased macrophages with hemophagocytic activity. They did not have peripheral lymphadenopathy. The complex clinical presentations simulated collagen vascular disorders, systemic infections, or severe liver disease rather than a malignant lymphoma. Routine histologic studies revealed a small population of lymphoma cells in the bone marrow, spleen, and liver. Immunophenotyping studies demonstrated their T-cell phenotype, and cytogenetic analysis showed the clonality in Patients 1 and 2; clonal T-cell receptor gene rearrangement was found in Patients 2 and 3. These studies should be considered in the evaluation of patients with constitutional symptoms, liver failure, coagulopathy, and pancytopenia even in the absence of peripheral lymphadenopathy.

Radiation-induced small bowel injury is a limiting factor to postoperative tumoricidal pelvic doses exceeding 4500 to 5000 cGy. Data from a review of the literature showed the inadequacy of medical measures and the bad reproducibility of radiation therapeutic attempts to decrease small intestine damage. Recent studies cited the benefit of a polyglycolic acid mesh to create an absorbable intestinal sling and suspend the loops above the pelvic radiation field. In 60 cases of gynecologic and rectal malignancies with a surgical intestinal morbidity of 8.3% (5 cases), the rate of radiation enteritis was 7% (4 cases) with an average follow-up of 17.8 months (range, 1 to 57 months). The quality of small intestinal elevation and the absence of loop herniation were demonstrated by the barium index. Magnetic resonance imaging was used for checking the polymer polyglycolic acid mesh position and its complete resorption at the third to fifth postoperative month. The authors conclude that this new procedure is safe in selected patients with high pelvic recurrence risk after optimal surgery, in residual disease after debulking surgery, or at the time of exploration for unresectable pelvic tumors. Clinical studies are ongoing to evaluate the long-term efficacy of this surgical technique to prevent chronic radiation enteropathy and improve locoregional control in advanced pelvic carcinomas.

Nine patients with lymphoma occurring in association with inflammatory bowel disease were admitted to The Mount Sinai Hospital between 1960 and 1983. Five (two men and three women) occurred among 1156 patients (0.43%) with ulcerative colitis (UC) and four (men), among 1480 patients (0.27%) with Crohn's disease (CD), a strong male preponderance in the latter group. In all four of the patients with CD and in four of the five patients with UC, the lymphomas were extraintestinal. The mean age of onset of UC in these patients was late (46 years, 19 years older than in our overall series), with lymphomas occurring a mean of only 12 years later. By contrast, patients with CD had bowel disease much younger (mean age, 26 years), and their lymphomas appeared after a longer disease duration (mean, 24 years). The risk factors for the one patient with colonic lymphoma were similar to those with colitis-associated colorectal carcinoma: extensive and long-standing colitis and relatively young age when malignant disease developed. Four of the patients with lymphoma had associated colonic carcinoma; in three of them, the carcinoma appeared within the first decade of colitis, an unusual occurrence. A second malignant lesion also occurred in three patients with UC.

Damage to bowel often complicates radiotherapy for abdominal and pelvic malignancy. The symptoms of chronic irradiation enteropathy, which often include intractable diarrhoea, are generally attributed to vascular injury. We have examined specimens of bowel resected from patients who had been therapeutically irradiated to assess the extent of injury to the enteric nerve plexuses. To facilitate visualisation of nerve fibres and cells of neural or neuroendocrine origin, sections were immunostained with antibodies to neuron-specific enolase or PGP 9.5, widely used markers of nerves and neurons. Electron microscopy was performed in selected cases. In 27 out of 33 specimens the number of nerve fibres in the lamina propria was obviously increased compared to that in control material. Scattered cells with the histological, immunohistochemical and ultrastructural features of ganglion cells were noted within the lamina propria in 23 of the specimens, and in 18 cases so-called neuroendocrine cells, not normally seen in this location, were also present. These radiation-induced changes in the innervation of the bowel may contribute to the symptoms of chronic radiation enteropathy.
