The basic problem of colonic surgery is the high septic risk. Especially chronic inflammatory diseases are marked by a high periintestinal infection rate. In addition, there are catabolisms with negative protein balance and immunologic deficiency. In order to avoid there factors the principle of withdrawal of the intestinal function has been applied. Patients are put on a balanced high-caloric and completely absorable diet (2,400-3,600 cal) using a thin duodenal tube for several weeks. Depending on the initial condition the alimentation is carried out in some patients parenterally or as a supplement. From 1966 to 1981 240 patients with ulcerative and granulomatous inflammatory diseases of the colon were operated on at the Surgical Department of the University Hospital Hamburg. Using this preparation the rate of infection decreased from 54 to 14%, and the mortality resulting from septic complications from 13 to 0.8%. The main achievement of withdrawal of the intestinal function is the reduction of extraintestinal secondary infection which is responsible for the septic complications.
BACKGROUND & AIMS: A specialized system for a new method for enteroscopy, the double-balloon method, was developed. The aim of this study was to evaluate the usefulness of this endoscopic system for small-intestinal disorders. METHODS: The double-balloon endoscopy system was used to perform 178 enteroscopies (89 by the anterograde approach and 89 by the retrograde approach) in 123 patients. The system was assessed on the basis of the rates of success in jejunal and ileal insertion and the entire examination of the small intestine, diagnostic yields, ability to perform treatment, and complications. RESULTS: Insertion of the endoscope beyond the ligament of Treitz or ileocecal valve was possible in all 178 procedures. It was possible to observe approximately one half to two thirds of the entire small intestine by each approach, and observation of the entire small intestine was possible in 24 (86%) of 28 trials. The source of bleeding was identified in 50 (76%) of 66 patients with GI bleeding, scrutiny of strictures was possible in 23 patients, and a tumor was examined endoscopically in 17 patients. Two complications (1.1%) occurred. Endoscopic therapies in the small intestine including hemostasis (12 cases), polypectomy (1 case), endoscopic mucosal resection (1 case), balloon dilation (6 cases), and stent placement (2 cases) were performed successfully. CONCLUSIONS: Double-balloon endoscopy permits the exploration of the small intestine with a high success rate of total enteroscopy. The procedure is safe and useful, and it provides high diagnostic yields and therapeutic capabilities.
A distinctive form of gastritis, characterized by lymphocytic infiltration of pit epithelium, has recently been described in association with evidence of Campylobacter pylori infection. We have evaluated simultaneous small bowel and gastric biopsies from 22 patients with diarrhea or malabsorption, all of which showed small bowel changes characteristic of sprue or spruelike disease. In 10 of 22 patients, striking lymphocytic gastritis was identified. Cases positive for lymphocytic gastritis had a mean of 46.5 lymphocytes per 100 epithelial cells, compared with a mean of 3.5 in normal gastric controls and 5.1 in abnormal controls, including cases with Campylobacter gastritis. Concurrent small bowel biopsies had a mean of 47.2 lymphocytes per 100 epithelial cells. Cases without lymphocytic gastritis had means of 10.8 and 39.9 lymphocytes per 100 gastric and intestinal epithelial cells, respectively. Campylobacter organisms were identified in only 1 of the 10 patients with lymphocytic gastritis and in 3 of the 12 patients without lymphocytic gastritis. Intraepithelial lymphocytes in small bowel and stomach were positive for the antibody MT-1, indicating a T-cell infiltrate at both sites. These findings suggest that lymphocytic gastritis may occur as a manifestation of celiac sprue or spruelike disease and that the lymphocytic infiltration of celiac sprue may affect gastric epithelial mucous cells.

Macrophages play a central role during the pathogenesis of inflammation. In normal intestinal mucosa surface expression of typical macrophage markers such as CD14, CD16, CD11b or T-cell co-stimulatory molecules such as CD80 or CD86 is low indicating anergy and low pro-inflammatory activity of these cells. During inflammatory bowel disease (IBD) the mucosa is invaded by a population of macrophages displaying these markers, secreting higher cytokine levels and representing an activated cell population. CD33(+) cells (macrophages) were isolated from normal and Crohn's disease mucosa and mRNA was isolated by polyT magnetic beads. A subtractive screening was performed subtracting mRNA from normal macrophages from those of Crohn's disease macrophages. Oxidative burst activity was determined by flow cytometry. Seventy clones were obtained by the subtractive mRNA screening. Sequencing showed > 99% homology to mRNA of monocyte chemoattractant protein-1 (MCP-1) for three clones. Five clones obtained by subtraction revealed > 99% homology to mRNA of cytochrome b (subunit gp91). Differential expression of the cytochrome b subunit gp91 and the cytosolic NADPH oxidase subunit p67 was confirmed by RT-PCR and 'virtual' Northern blots. The fluorescence ratio of stimulated versus unstimulated cells was 0.9 +/- 0.16 in control macrophages indicating a lack of oxidative burst activity. In Crohn's disease this ratio was significantly increased to 1.80 +/- 0.8 (P = 0.004) confirming the molecular data. In conclusion NADPH oxidase mRNA is down-regulated or absent in macrophages from normal mucosa correlating with a lack of oxidative burst activity. In IBD macrophage-oxidative burst activity is increased and NADPH oxidase mRNA induced. Inhibition of NADPH oxidase could be a new therapeutical target in IBD and reduce mucosal tissue damage in active IBD.

Among the numerous breath tests described for gastroenterological applications, breath hydrogen (H2) tests have emerged during the past two decades as a most sensitive, reliable and feasible method for detecting carbohydrate malabsorption and maldigestion (e. g. lactose maldigestion). Hence they are regarded time honored standards of contemporary gastroenterological function tests. For the diagnosis of the small bowel bacterial overgrowth syndrome the glucose H2 breath test is a feasible tool with moderate sensitivity (approximately 65%), which, however, is not higher with alternative breath test (e. g. the 1 g 14C-D-xylose breath test). Measuring mouth-to-caecum-transit time by the breath H2 response after lactulose is more of scientific interest than clinically informative. Breath tests making use of 14C labeled substrates (usually 5 to 10 microCi) bear a rather low calculated radiation hazard and are thus in routine use in some countries, e. g. in Scandinavia, but they are abandoned in others. At least, however, radioactive 14C breath tests are (partially) dispensible, as these restrictions do not apply for the stable isotope 13C breath tests which are nonradioactive and thus devoid of any radiation hazard. For the purpose of gastroenterological function testing the 13C urea breath test for the detection of Helicobacter pylori infection, quantitative studies of gastric emptying with 13C-acetate or 13C-octanoate and quantitative liver function tests have gained diagnostic use while 13C-breath tests assessing intestinal absorption or exocrine pancreatic function have been found less effective than the respective alternatives, or too expensive. Both, H2-breath tests and 13CO2-breath tests are clinically important, diagnostic methods with well delineated indications in gastroenterology.

The preparation Mutaflor contains a defined strain of physiological E. coli bacteria. One hundred and sixty-seven physicians documented the treatment of 1,074 patients suffering from functional or chronic inflammatory bowel disease. For all indications the tolerance of Mutaflor was judged to be good to very good in over 90% of the cases. Adverse reactions which needed treatment or led to termination of the therapy, were reported in 1.5% of the cases. Initially occurring side effects, which did not need treatment and disappeared spontaneously, were observed in 2.8% of the cases. Interactions with additional or concomitant drugs did not occur. As a parameter for the evaluation of efficacy, the subjective assessment of the results by physicians and patients was used. In 84% of the patients with functional intestinal disorders and 78% of the patients with chronic inflammatory bowel disease results of treatment were judged to be good to very good.
