  6. Examination of coated tablet of 99Tcm-5-aminosalicylic acid for delivering drug in colon

    The radionuclide trace technique is used to examine and determine that 99Tcm-5-aminosalicylic acid coated table delivere drug in colon. 5-aminosalicylic acid labelled with 99Tcm is made to be coated tablet. Which character in artificial gastrointestinal liquid is observed by testing radioactivity leakage of the coated tablet, and in dogs vivo motor process by SPECT. Coated tablet is not dissolved in artificial gastric juice and outward appearance of which does not change. Coated table is take out after laid in artificial gastric juice for 1 h and placed in artificial intestinal liquid, partial coating is corroded and appears a great quantity of hole in a utensil at 3 h, and coating starts to burst and release at 3.5 h. The coated tablet starts to release drug in ascending colon and remain in colon for 6-7 h after taking orally. Therefore coated table of 99Tcm-5-aminosalicylic acid is able to release drug by location in colon. (authors)

    2006-01-01

    Full Text Available Mutual azo prodrug of 5-aminosalicylic acid with histidine, was synthesized by coupling L-histidine with salicylic acid, for targeted drug delivery to the inflamed gut tissue, in inflammatory bowel disease. In vitro kinetic studies in HCl buffer (pH 1.2 showed negligible release of 5-aminosalicylic acid, whereas in phosphate buffer (pH 7.4, only 14% release was observed over a period of 6h. In rat fecal matter, the release of 5-aminosalicylic acid was almost complete (85.6%, with a half life of 163 min, following zero order kinetics. The azo conjugate was evaluated for its ulcerogenic potential by Rainsford′s cold stress method. Therapeutic efficacy of the carrier system and the mitigating effect of the azo conjugate were evaluated in trinitrobenzenesulphonic acid- induced experimental colitis model. The synthesized prodrug was found to be equally effective in mitigating the colitis in rats, as that of sulfasalazine, without the ulcerogenicity of 5-aminosalicylic acid, and adverse effects of sulfasalazine.

  11. Pharmacokinetics and tissue distribution of 14C-5-aminosalicylic acid (14C-5-ASA) in rats

    5-Aminosalicylic acid (5-ASA) is effective in the treatment of ulcerative colitis and Crohn's disease. As part of a preclinical metabolism profile with 5-ASA, we evaluated the tissue level and distribution of 14C-5-ASA in rats. Biodistribution of 14C-radioactivity was determined in the major organs of rats after a single oral dose (34 mg/kg; 15 uci/rat). Data from tissue area under the curve (AUC 0-72) indicated that the highest amounts of radioactivity were retained in cecum (481.1 hr.ug.equ/gm), colon-rectum (178.5 hr.ug.equ/gm), ileum (166.7 hr.ug.equ/gm), jejunum (65.5 hr.ug.equ/gm), followed by kidneys (58.0 hr.ug.equ/gm) and liver (14.8 hr.ug.equ/gm). The radioactivity retained in tissues at 72 hours postdose was wither nondetectable or less than 0.1 ppm. The radioactivity concentration in blood was highest at 0.5 hr (tmax) postdose and the terminal half-life (t1/2) of 14C-radioactivity (5-ASA + metabolite) was 2.7 hours. 14C-5-ASA is absorbed and distributed in the body. The greatest amount of 14C-radioactivity was found in the stomach and GI tract. 14C-5-ASA was eliminated completely (44.9% in the urine, 51.7% in the feces) 72 hours after administration without significant tissue retention

    Prosberg, Michelle V; Vester-Andersen, Marianne K; Andersson, Mikael; Jess, Tine; Andersen, Jon T; Vind, Ida; Bendtsen, Flemming

    2016-01-01

    BACKGROUND: Noncompliance to long-term medical therapy is a well-known problem among patients treated for ulcerative colitis, but studies of long-term consequences in unselected patients are lacking. The authors aimed to determine the risk of recurrence according to long-term compliance with oral 5......-aminosalicylic acid among unselected patients with ulcerative colitis. METHODS: The authors conducted a 7-year follow-up study of a population-based inception cohort of 243 Danish patients with ulcerative colitis diagnosed from 2003 to 2004. Compliance was defined as consumption of ≥80% of prescribed oral 5...... treatment, or colectomy) in compliant versus noncompliant patients. RESULTS: In total, 182 patients(75%) experienced at least 1 recurrence during follow-up. For the first year after diagnosis, risk of recurrence did not differ significantly between compliant and noncompliant patients. For 1 to 3 years...

  13. The prophylactic effect of 5-aminosalicylic acid and salazosulphapyridine on degraded-carrageenan-induced colitis in guinea pigs

    Poulsen, Steen Seier

    1984-01-01

    placebo group, all guinea pigs developed many small punctiform ulcerations in the cecum (median, 30/cm2). In the 5-ASA group no protective effect was demonstrated, since the number of ulcerations was 37/cm2. The difference is not statistically significant. However, the SASP group presented significantly......Experimental colitis was induced in guinea pigs by administration of 5% degraded carrageenan for 5 days. The prophylactic effect of a slow-release preparation of 5-aminosalicylic acid (5-ASA; 13 mg/100 g/day) was compared with approximately equimolar amounts of salazosulphapyridine (SASP; 26 mg/100...... fewer ulcerations (4/cm2). The concentrations of 5-ASA and/or its acetylated metabolite were several times higher in the cecum content and twice as high in plasma in the SASP group, indicating a difference in the absorption patterns of 5-ASA and the two drugs. These results and the etiological...

  14. Inhibitory Effect of Flavonoids on the Efflux of -Acetyl 5-Aminosalicylic Acid Intracellularly Formed in Caco-2 Cells

    Shin Yoshimura

    2009-01-01

    Full Text Available -acetyl 5-aminosalicylic acid (5-AcASA that was intracellularly formed from 5-aminosalicylic acid (5-ASA at 200 M was discharged 5.3, 7.1, and 8.1-fold higher into the apical site than into the basolateral site during 1, 2, and 4-hour incubations, respectively, in Caco-2 cells grown in Transwells. The addition of flavonols (100 M such as fisetin and quercetin with 5-ASA remarkably decreased the apically directed efflux of 5-AcASA. When 5-ASA (200 M was added to Caco-2 cells grown in tissue culture dishes, the formation of 5-AcASA decreased, and, in addition, the formed 5-AcASA was found to be accumulated within the cells in the presence of such flavonols. Thus, the decrease in 5-AcASA efflux by such flavonols was attributed not only to the inhibition of -acetyl-conjugation of 5-ASA but to the predominant cellular accumulation of 5-AcASA. Various flavonoids also had both of the effects with potencies that depend on their specific structures. The essential structure of flavonoids was an absence of a hydroxyl substitution at the C5 position on the A-ring of flavone structure for the inhibitory effect on the -acetyl-conjugation of 5-ASA, and a presence of hydroxyl substitutions at the C3 or C4 position on the B-ring of flavone structure for the promoting effect on the cellular accumulation of 5-AcASA. Both the decrease in 5-AcASA apical efflux and the increase in 5-AcASA cellular accumulation were also caused by MK571 and indomethacin, inhibitors of MRPs, but not by quinidine, cyclosporin A, P-glycoprotein inhibitors, and mitoxantrone, a BCRP substrate. These results suggest that certain flavonoids suppress the apical efflux of 5-AcASA possibly by inhibiting MRPs pumps located on apical membranes in Caco-2 cells.

    2016-09-01

    In this work, thiolated chitosan/alginate composite microparticulates (CMPs) coated by Eudragit S-100 were developed for colon-specific delivery of 5-aminosalicylic acid (5-ASA) and curcumin (CUR), and the use of it as a multi drug delivery system for the treatment of colitis. The physicochemical properties of the CMPs were evaluated. In vitro release was performed in gradually pH-changing medium simulating the conditions of different parts of GIT, and the results showed that the Eudragit S-100 coating has a pH-sensitive release property, which can avoid drug being released at a pH lower than 7. An everted sac method was used to evaluate the mucoadhesion of CMPs. Ex vivo mucoadhesive tests showed CMPs have excellent mucosa adhesion for the colonic mucosa of rats. In vivo treatment effect of enteric microparticulates systems was evaluated in colitis rats. The results showed superior therapeutic efficiency of this drug delivery system for the colitis rats induced by TNBS. Therefore, the enteric microparticulates systems combined the properties of pH dependent delivery, mucoadhesive, and control release, and could be an available tool for the treatment of human inflammatory bowel disease.

  17. 5-aminosalicylic acid is an attractive candidate agent for chemoprevention of colon cancer in patients with inflammatory bowel disease

    Yang Cheng; Pierre Desreumaux

    2005-01-01

    Inflammatory bowel disease (IBD) is classically subdivided into ulcerative colitis (UC) and Crohn's disease (CD). Patients with IBD have increased risk for colorectal cancer. Because the pathogenesis of colorectal carcinoma has not been entirely defined yet and there is no ideal treatment for colon cancer, cancer prevention has become increasingly important in patients with IBD. The two adopted methods to prevent the development of colon cancer in clinical practice include the prophylactic colectomy and colonoscopic surveillance.But patients and physicians seldom accept colectomy as a routine preventive method and most patients do not undergo appropriate colonoscopic surveillance. Chemoprevention refers to the use of natural or synthetic chemical agents to reverse, suppress, or to delay the process of carcinogenesis.Chemoprevention is a particularly useful method in the management of patients at high risk for the development of specific cancers based on inborn genetic susceptibility, the presence of cancer-associated disease, or other known risk factors. Prevention of colorectal cancer by administration of chemopreventive agents is one of the most promising options for IBD patients who are at increased risks of the disease. The chemopreventive efficacy of nonsteroidal antiinflammatory drugs (NSAIDs) against intestinal tumors has been well established. But with reports that NSAIDs aggravated the symptoms of colitis, their sustained use for the purpose of cancer chemoprevention has been relatively contraindicated in IBD patients. Another hopeful candidate chemoprevention drug for IBD patients is 5-aminosalicylic acid (5-ASA), which is well tolerated by most patients and has limited systemic adverse effects, and no gastrointestinal toxicity. 5-ASA lacks the well-known side effects of longterm NSAIDs use. Retrospective correlative studies have suggested that the long-term use of 5-ASA in IBD patients may significantly reduce the risk of development of colorectal cancer

  19. 5-Aminosalicylic Acid Azo-Linked to Procainamide Acts as an Anticolitic Mutual Prodrug via Additive Inhibition of Nuclear Factor kappaB.

    Kim, Wooseong; Nam, Joon; Lee, Sunyoung; Jeong, Seongkeun; Jung, Yunjin

    2016-06-01

    To improve the anticolitic efficacy of 5-aminosalicylic acid (5-ASA), a colon-specific mutual prodrug of 5-ASA was designed. 5-ASA was coupled to procainamide (PA), a local anesthetic, via an azo bond to prepare 5-(4-{[2-(diethylamino)ethyl]carbamoyl}phenylazo)salicylic acid (5-ASA-azo-PA). 5-ASA-azo-PA was cleaved to 5-ASA and PA up to about 76% at 10 h in the cecal contents while remaining stable in the small intestinal contents. Oral gavage of 5-ASA-azo-PA and sulfasalazine, a colon-specific prodrug currently used in clinic, to rats showed similar efficiency in delivery of 5-ASA to the large intestine, and PA was not detectable in the blood after 5-ASA-azo-PA administration. Oral gavage of 5-ASA-azo-PA alleviated 2,4,6-trinitrobenzenesulfonic acid-induced rat colitis. Moreover, combined intracolonic treatment with 5-ASA and PA elicited an additive ameliorative effect. Furthermore, combined treatment with 5-ASA and PA additively inhibited nuclear factor-kappaB (NFκB) activity in human colon carcinoma cells and inflamed colonic tissues. Finally, 5-ASA-azo-PA administered orally was able to reduce inflammatory mediators, NFκB target gene products, in the inflamed colon. 5-ASA-azo-PA may be a colon-specific mutual prodrug acting against colitis, and the mutual anticolitic effects occurred at least partly through the cooperative inhibition of NFκB activity.

    2013-09-01

    The object of this study was to investigate the effect of probiotic Escherichia coli strain Nissle 1917 (EcN) (i) EcN lipopolysaccharide (EcN LPS) and (ii) bacteria-free supernatant of EcN suspension (EcN supernatant) on in vitro transepithelial transport of mesalazine (5-aminosalicylic acid, 5-ASA), the most commonly prescribed anti-inflammatory drug in inflammatory bowel disease (IBD). Effect of co-administered EcN LPS (100 µg/ml) or EcN supernatant (50 µg/ml) on the 5-ASA transport (300 µmol/l) was studied using the Caco-2 monolayer (a human colon carcinoma cell line) as a model of human intestinal absorption. Permeability characteristics for absorptive and secretory transport of parent drug and its intracellularly-formed metabolite were determined. The quantification of 5-ASA and its main metabolite N-acetyl-5-amino-salicylic acid (N-Ac-5-ASA) was performed by high performance liquid chromatography. Obtained results suggest that neither EcN LPS nor EcN supernatant had effect on the total 5-ASA transport (secretory flux greater than absorptive flux) and on the transport of intracellularly formed N-Ac-5-ASA (preferentially transported in the secretory direction). The percent cumulative transport of the total 5-ASA alone or in combination with EcN LPS or EcN supernatant did not exceed 1%. PMID:23846256

  1. Novel pH-sensitive hydrogels for 5-aminosalicylic acid colon targeting delivery: in vivo study with ulcerative colitis targeting therapy in mice.

    2016-07-01

    Current guidelines recommend patients with active and mild-to-moderate ulcerative colitis (UC), who have received initial therapy with 5-aminosalicylic acid (5-ASA). In this study, a novel drug delivery vehicle achieved by pH-sensitive hydrogels was applied to 5-ASA. In our previous work, a novel P(CE-MAA-MEG) pH-sensitive hydrogel was successfully synthesized by the heat-initiated free radical polymerization method. The aim of this study is to investigate its site-specific delivering of drugs to the colon and evaluate its colon-targeting characteristic in vivo. 5-ASA was chosen as a model drug and successfully loaded in the hydrogel. In vitro investigations were carried out to evaluate its release process. Above all, animal treatment results reveal an obvious effect on the UC healing. Therefore, all results suggested that the developed 5-ASA-P(CE-MAA-MEG) hydrogel (5-ASA-GEL) as a colon-targeting vector might have a great potential application in the UC therapy. PMID:25693641

    As we all known that diabetes is a chronic disease with major health consequences.Research has revealed that the occurrence of diabetes have great thing to do with the chromium deficient. Almost 40 years after the first report of glucose tolerance factor(GTF) [1], no conclusive evidence for an isolable ,biologically active form of chromium exited. Three materials have been proposed to be the biologically active form of chromium: "glucose tolerance factor", chromium Picolinate and low-molecular-weight chromium-binding substance (LWMCr) [2] . So there is potential for the design of new chromium drugs .5-Aminosalicylic acid (5-ASA) is identified as an active component in the therapy of inflammatory bowel disease (IBD) such as Crohn's disease and ulcerative colitis . The therapeutic action of 5-ASA is believed to be coupled to its ability to act as a free radical scavenger [3-4],acting locally on the inflamed colonic mucosa [5-7]. However, the clinical use of 5-ASA is limited, since orally administered 5-ASA is rapidly and completely absorbed from the upper gastrointestinal tract and therefore the local therapeutic effects of 5-ASA in the colon is hardly expected.In this paper, we report the synthesis of chromium(Ⅲ)5-aminosalicylate from 5-ASA and CrCl3. 6H2O.The synthesis route is as follow:The complex has been characterized by elemental analysis, IR spectra, X-ray powder diffractionand TG-DTA . They indicate that the structure is tris(5-ASA) Chromium . Experiments show that thecomplex has a good activity for supplement tiny dietary chromium, lowering blood glucose levels,lowering serum lipid levels and in creasing lean body mass .

  4. Antioxidant activities and radical scavenging activities of flavonoids studied by the electrochemical methods and ESR technique based on the novel paramagnetic properties of poly(aniline-co-5-aminosalicylic acid)

    Graphical abstract: ESR spectra of the PAASA/RGO/graphite electrodes: (1) in the buffer solution consisting of 0.20 M phosphate and methanol (80: 20, v/v), (2) in the buffer solutions containing 150 μM of (+)-catechin. -- Abstract: Four kinds of flavonoid, viz. flavanone naringenin, Flavone apigenin, flavonol kaempferol, and flavanol (+)-catechin, are used to investigate their antioxidant and radical scavenging activitis in the water-methanol solution of pH 6.3, using the electrochemical methods and electron spin resonance (ESR) technique. Poly(aniline-co-5-aminosalicylic acid) (PAASA) is first used as a radical source that was polymerized on a reduced graphene oxide (RGO)/glassy carbon (GC) disk or on the RGO/graphite fiber electrode. The assessment of the antioxidant activities is performed using both cyclic voltammetry and the open circuit potential measurement. On the basis of results from both electrochemical mathods, the order of the antioxidant actitvities of flavonoids is as follows: (+)-catechin > kaempferol > apigenin > naringenin However, the difference in the antioxidant activities between naringenin and apigenin is very small. On the basis of the ESR signal intensities of PAASA, the order of the radical scavenging activities of flavonoids is in good agreement with that of the above antioxdant activities.Three oxidation peaks on the cyclic voltammograms of (+)-catechin are first detected, which gives us a deep insight into the oxidation mechanism of (+)-catechin

  5. Pharmacokinetics in Wistar Rats of 5-[(4-Carboxybutanoyl)Amino]-2-Hydroxybenzoic Acid: A Novel Synthetic Derivative of 5-Aminosalicylic Acid (5-ASA) with Possible Anti-Inflammatory Activity

    Correa-Basurto, José; Rosales Hernández, Martha Cecilia; Padilla Martínez, Itzia Irene; Mendieta-Wejebe, Jessica Elena

    2016-01-01

    5-[(4-carboxybutanoyl)amino]-2-hydroxybenzoic acid (C2) is a novel synthetic derivative of 5-aminosalicylic acid (5-ASA), which is currently being evaluated ex vivo as an anti-inflammatory agent and has shown satisfactory results. This study aimed to obtain the pharmacokinetic profiles, tissue distribution and plasma protein binding of C2 in Wistar Rats. Additionally, an HPLC method was developed and validated to quantify C2 in rat plasma. The pharmacokinetic profiles of intragastric, intravenous and intraperitoneal administration routes at singles doses of 100, 50, and 100 mg/kg, respectively, were studied in Wistar rats. The elimination half-life of intravenously administered C2 was approximately 33 min. The maximum plasma level of C2 was reached approximately 24 min after intragastric administration, with a Cmax value of 2.5 g/mL and an AUCtot value of 157 μg min-1/mL; the oral bioavailability was approximately 13%. Following a single intragastric or oral dose (100 mg/kg), C2 was distributed and detected in all examined tissues (including the brain and colon). The results showed that C2 accumulates over time. The plasma protein binding results indicated that the unbound fraction of C2 at concentrations of 1 to 20 μg/mL ranged from 89.8% to 92.5%, meaning that this fraction of C2 is available to cross tissues. Finally, the blood-plasma partitioning (BP ratio) of C2 in rat plasma was 0.71 and 0.6 at concentrations of 5 and 10 μg/mL, respectively, which indicates that C2 is free in the plasmatic phase and not inside blood cells. The results of this study suggest that a fraction of the administered C2 dose is absorbed in the stomach, and the fraction that is not absorbed reaches the small intestine and colon. This distribution constitutes the main advantage of C2 compared with 5-ASA for the treatment of ulcerative colitis (UC) and Crohn's disease (CD). PMID:27454774

    AIM: To investigate the release of cyclodextrin-5-amino salicylic acid (CyD-5-ASA) in cecum and colon.METHODS: An anti-inflammatory drug 5-ASA was conjugated onto the hydroxyl groups of α-, β- and γ-cyclodextrins (CyDs) through an ester linkage, and the in vivo drug release behavior of these prodrugs in rat' s gastrointestinal tract after the oral administration was investigated.RESULTS: The 5-ASA concentration in the rat's stomach and small intestine after the oral administration of CyD5-ASA conjugate was much lower than that after the oral administration of 5-ASA alone. The lower concentration was attributable to the passage of the conjugate throughthe stomach and small intestine without significant degradation or absorption, followed by the degradation of the conjugate site-specific in the cecum and colon. The oral administration of CyD-5-ASA resulted in lower plasma and urine concentration of 5-ASA than that of 5-ASA alone.CONCLUSION: CyD-5-ASA conjugates may be used as prodrugs for colon-specific drug delivery system.

  12. Common misconceptions about 5-aminosalicylates and thiopurines in inflammatory bowel disease

    Javier P Gisbert; María Chaparro; Fernando Gomollón

    2011-01-01

    Misconceptions are common in the care of patients with inflammatory bowel disease (IBD). In this paper, we state the most commonly found misconceptions in clinical practice and deal with the use of 5-aminosalicylates and thiopurines, to review the related scientific evidence, and make appropriate recommendations. Prevention of errors needs knowledge to avoid making such errors through ignorance. However, the amount of knowledge is increasing so quickly that one new danger is an overabundance of information. IBD is a model of a very complex disease and our goal with this review is to summarize the key evidence for the most common daily clinical problems. With regard to the use of 5-aminosalicylates, the best practice may to be consider abandoning the use of these drugs in patients with small bowel Crohn' s disease. The combined approach with oral plus topical 5-aminosalicylates should be the first-line therapy in patients with active ulcerative colitis; once-daily treatment should be offered as a first choice regimen due to its better compliance and higher efficacy. With regard to thiopurines, they seem to be as effective in ulcerative colitis as in Crohn' s disease. Underdosing of thiopurines is a form of undertreatment. Thiopurines should probably be continued indefinitely because their withdrawal is associated with a high risk of relapse. Mercaptopurine is a safe alternative in patients with digestive intolerance or hepatotoxicity due to azathioprine. Finally, thiopurine methyltransferase (TPMT) screening cannot substitute for regular monitoring because the majority of cases of myelotoxicity are not TPMT-related.

  15. Severe chest pain in a pediatric ulcerative colitis patient after 5-aminosalicylic acid therapy

    2008-01-01

    Severe reactions to mesalamine products are rarely seen in pediatric patients. We report a case of a 12-year-old boy who had a severe cardiac reaction to a mesalamine product Asacol. Past medical history is significant for ulcerative colitis (UC) diagnosed at 9 years of age. Colo- noscopy one week prior to admission revealed pancoli- tis. He was treated with Asacol 800 mg three times per day and prednisone 20 mg/d. He was subsequently ad- mitted to the hospital for an exacerbation of his UC and started on intravenous solumedrol. He had improvement of his abdominal pain and diarrhea. The patient com- plained of new onset of chest pain upon initiating Asacol therapy. Electrocardiogram (ECG) revealed non-specific ST-T wave changes with T-wave inversion in the lateral leads. Echocardiogram (ECHO) revealed low-normal to mildly depressed left ventricular systolic function. The left main coronary artery and left anterior descending artery were mildly prominent measuring 5 mm and 4.7 mm, respectively. His chest pain completely resolved within 24-36 h of discontinuing Asacol. A repeat echo- cardiogram performed two days later revealed normal left ventricular function with normal coronary arteries (< 3.5 mm). Onset of chest pain after Asacol and im- mediate improvement of chest pain, as well as improve- ment of echocardiogram and ECG findings after discon- tinuing Asacol suggests that our patient suffered from a rare drug-hypersensitivity reaction to Asacol.

  1. Double-contrast enema

    A solid state digital system (FCR 101) was employed in our comparative evaluation of the image quality of conventional versus digital techniques in the study of colon by means of double-contrast enema. Sixty patients were examined with a single AP view, using digital radiography with 100% radiation dose and progressive 50% and 75% reductions; the radiographs thus obtained were then compared with the corresponding conventional ones. The examined parameters were organ profile and mucosal pattern. Each digital and conventional radiographs was evaluated by 2 independent radiologists and a value is given to each parameter i.e., 1=good, 2=sufficient, 3=insufficient. Upon comparison of the average values obtained for digital and conventional radiographs in optimal conditions and with a dose reduced by 50%, the digital technique was seen to give a more detailed and accurate representation of both low-contrast mucosal pattern and of organ profile. With the dose reduced by 75%, a slight increase was observed in background noise which caused a slight loss in image definition, but this did not reduce image readability with respect to conventional radiographs. To conclude, the digital method with a 50% exposure reduction is to be preferred in the examination of the colon, especially in pediatric radiology; furthermore, since this technique allows better detailing at lower contrast, it is ot be preferred in the study of the pathologic conditions affecting mainly/only the mucosal pattern-e.g., cancer, ulcerative colitis, Crohn's disease, and so on. An exposure dose reduced by 75% may be used for following lesions previously diagnosed and when a less detailed depiction of the mucosal pattern is enough

    Contrast enema was performed in a select group of 126 neonates with ambiguous diagnosis of necrotizing enterolcolitis (NEC). Enema findings were compared with that on plain abdominal radiographs (AXR) and the clinical outcome. Thirty-one of the 34 patients with a discharge diagnosis of NEC were interpreted to have a positive contrast enema, and 91 of the 92 patients without a discharge diagnosis of NEC were interpreted to have a negative contrast enema. The AXR was interpreted as positive in 57 patients and as negative or indeterminate in 69. Not a single case of perforation was produced. Judicious use of contrast enema can improve specificity of diagnosis in cases with discordant clinical and plain radiographic findings. (orig.).

    A new technic of the barium enema was proposed for the better colonic double contrast study with the average 204ml of 50w/v% barium, applied to 109 serial patients. The barium was introduced to sigmoid colon, and then pushed to a mid transverse colon by the air insufflation through an enema syringe, a new device. An advance to cecum is accomplished by the air insufflation and/or the position change of the patient. The barium transfer method was developed for the best spot film exposure, through colon, by the position change of the patient, the tilting of the x-ray table and the air insufflation with the enema syringe. The mean angle of the x-ray table tilted was -10 .deg. at the beginning the barium enema till the barium sent past the splenic flexure, -15 . deg. for the best lateral view of rectum and -18 .deg. for the bet prone PA view of rectosigmoid colon. This was a simple, better and economic double contrast barium enema for the cooperative patients.

    Full Text Available OBJECTIVES: To study the effect of short-chain fatty-acids on atrophy and inflammation of excluded colonic segments before and after the development of diversion colitis. INTRODUCTION: Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, possibly evolving with mucous and blood discharge. The most favored hypotheses to explain its development is short-chain fatty-acid deficiency in the colon lumen. METHODS: Wistar rats were submitted to colostomy with distal colon exclusion. Two control groups (A1 and B1 received rectally administered physiological saline, whereas two experimental groups (A2 and B2 received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively, whereas the B groups were therapeutically treated (after post-operative day 40. The mucosal thickness of the excluded colon was measured histologically. The inflammatory reaction of the mucosal lamina propria and the lymphoid tissue response were quantified through established scores. RESULTS: There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001, which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126 and in the intestinal lumen (p = 0.0256. Group A2 showed no mucosal thickness recovery and significant increases in the numbers of lymphocytes (p = 0.0006 and eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022. CONCLUSION: Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy.

  10. Enterogastroesophageal reflux during barium enema: Report of a case

    Enterogastric reflux during barium enema examination has been ascribed to various causes including incompetence of the ilepcecal valve, shunt, fistula, excessive barium etc. Recently we have encountered a case of complete enterogastroesphageal regurgitation during barium enema examination performed for the reduction of the ileocolic intuosusception in 6 months old baby. The regurgitation occurred only in the first of two barium enema examinations conducted at one month interval for recurring intussusception. The barium-saline solution used in the present study was not more than 350 ml in quantity. No organic or physical causes of such a complete regurgitation could be determined

    In this study, water soluble hyaluronic acid (HA) based hydroxamate and conjugates with biologically active amines and hydrazides such as p- and o-aminophenols, anthranilic, 4- and 5-aminosalicylic acids, nicotinic, N-benzylnicotinic and isonicotinic hydrazides, p-aminobenzenesulfonamide (Streptocide), p-aminobenzoic acid diethylaminoethyl ester (Procaine), and 4-amino-2,3-dimethyl-1-phenyl-3-pyrazolin-5-one (4-aminoantipyrene) were examined as matrix metalloproteinase-2 inhibitors (MMPIs). In a dose of 0.27-270μM, the most efficient MMPIs were HA conjugates with o-aminophenol=4-aminoantipyrine>4-aminosalicylic acid>5-aminosalicylic acid. Conjugates with Streptocide, Procaine and HA hydroxamate showed 40-50% inhibitory effect at all used concentrations. Conjugates with anthranilic acid and isonicotinic hydrazide (Isoniazid) in a dose of 0.27μM inhibited enzyme activity by ∼70%, but with the concentration increase their inhibitory effect was decreased.

    Purpose: To compare the accuracy of multidetector computerized tomography enema (MDCT-e) and magnetic resonance enema (MRI-e) in determining the presence of sigmoid and rectal endometriotic nodules. Materials and methods: 260 women (32.6 ± 4.3 years) with symptoms suggestive of rectosigmoid endometriosis underwent MDCT-e and MRI-e prior to laparoscopy. After retrograde colonic distention and injection of intravenous contrast medium, patients were scanned on a 64-row MDCT scanner. MRI-e was performed on a 1.5 T magnet using an 8 channels phased array coil; intestinal distention was achieved by introducing in the rectum 250–300 ml of ultrasonographic gel diluted with saline solution. Radiological findings were compared with surgical and histological results. Results: 176 women had rectosigmoid endometriosis at surgery. There was no significant difference in the accuracy of MDCT-e (98.5%) and MRI-e (96.9%) in the diagnosis of sigmoid and rectal endometriosis (p = 0.248). The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio and negative likelihood ratio of MDCT-e and MRI-e were respectively 98.3%, 98.8%, 99.4%, 96.5%, 81.59, 0.02 and 97.2%, 96.4%, 98.3%, 94.1%, 26.89, 0.03. Conclusions: Both MDCT-e and MRI-e are accurate in the diagnosis of rectal and sigmoid endometriosis.

  14. Barium enema findings of milk allergy in infants

    We wanted to evaluate the barium enema findings of milk allergy in infants. Retrospective evaluation of the plain abdominal radiography and barium enema findings was performed in fifteen young infants suffering with milk allergy. The presence of gaseous distension, rectal gas, paralytic ileus and mechanical obstruction was evaluated on the plain radiography. The presence of spasm, a transitional zone, a reversed rectosigmoid index and mucosal irregularity was analyzed on the barium enema; the presence of barium retention was also evaluated on 24-hour-delayed plain radiography. Paralytic ileus was the most common finding on the plain radiography (93%). On the barium enema, continuous spasm of the colon, ranging from the rectum to the descending colon, was revealed in ten infants (67%). A transitional zone was observed in one infant and a reversed rectosigmoid index was revealed in four. Mucosal irregularity was observed in two infants. Barium retention was demonstrated in 11 of fifteen cases: throughout the entire colon (n = 3), from the rectum to the descending colon (n = 7), and up to the transverse colon (n = 1). The most common barium enema finding of milk allergy in infants was spasm of the distal colon. The other findings were a transitional zone, a reversed rectosigmoid index, mucosal irregularity and barium retention

  15. The diagnostic value of barium enema in acute appendicitis

    Acute appendicitis is the most common acute surgical condition of the abdomen. When the clinical presentation is atypical, barium enema has proven to be safe and useful in confirming the diagnosis and reducing the negative surgical exploration. However, the performance of barium enema in acute appendicitis has known contraindication primarily because of fear of leakage by perforation of the inflamed appendix. This study using barium enema as a diagnostic aid in acute appendicitis with atypical clinical presentation was performed to further support the previously noted efficacy and safety of this procedure. The results were as followings: 1. In case of acute appendicitis with atypical clinical presentation, the use of barium enema as a diagnostic aid increased the accuracy of diagnosis and decreased the negative surgical exploration. In women between 11 to 50 years old age, especially, it played important role differentiating appendicitis from nonsurgical acute abdomen. 2. The results of the study were 92.31% in sensitivity, 7.69% in false positive, 6.9% in false negative, and 10.26% in negative appendectomy. 3. None of case of leakage of barium by perforation of the inflamed appendix was noted, therefore, barium enema was thought to be safe as a diagnostic aid in acute appendicitis. 4. A simple partial or non filling of appendix without other associated positive finding could not exclude appendicitis, therefore, close clinical observation was necessary. 5. The positive findings of barium enema and their sensitivity were as followings: 1. Non filling of appendix: 90% 2. Partial filling of appendix: 91.7% 3. Displacement or a local impression on terminal ileum: 100%

    Full Text Available Introduction. Intussusception is a common abdominal emergency in infants and children. Ultrasonography and barium enema are very useful in diagnosis and treatment of this condition. The aim of the study was to assess the accuracy of ultrasound-guided saline enema for intussusception and to determine if some factors may improve the outcome of this technique. Material and methods. Intussusception was diagnosed in 63 patients at the Clinic of Pediatric Surgery in Novi Sad. The study period was divided into two 2-year phases: phase I, from 2001 through 2002, and phase II, from 2003 through 2004. During phase I, besides barium enema and fluoroscopy, we started using ultrasonography and ultrasound-guided hydrostatic saline enema in the diagnosis and reduction of intussusception. In phase II, this method of reduction was routinely used in all cases. Our technique of ultrasonic reduction was similar to the conventional hydrostatic barium reduction, except the reservoir was higher than that of barium, analgosedation ot patients was performed and in case of difficult and prolonged reduction, gentle manual pressure to the abdomen at right lower quadrant was used. Results. In phase I the diagnostic accuracy of ultrasonography in detecting intussusception was 53.8% , and 100% in phase II. The success rate of ultrasound-guided saline enema was 55.5% in phase I, and 83.8% in phase II. Only 6 patients (16.2% underwent operative manual reduction of intussusception in phase II. There were no cases with bowel gangrene or perforations in both groups. Conclusions. Ultrasonography is a useful screening tool in the diagnosis of intussusception. The main advantage of hydrostatic reduction with ultrasound guidance is avoidance of ionizing radiation. The success rate of this method of reduction may be increased with an integrated team approach to the management and with modifications of the technique.

    Full Text Available Nadine van Dongen,1 Ad A Kaptein21Patient Intelligence Panel, London, United Kingdom; 2Medical Psychology, Leiden University Medical Centre, Leiden, The NetherlandsPurpose: To gain insight from people in The Netherlands with inflammatory bowel disease (IBD on their experiences with enema use, and their views on the use of enemas and mode of enema delivery.Methods: A total of 112 patients from The Netherlands with physician-diagnosed Crohn's disease, ulcerative colitis, or other intestinal problems completed an online questionnaire of 24 questions. These included: sociodemographic and clinical characteristics, enema use, adherence, perceived advantages/disadvantages of enema use, ideal enema design, and patient views on medication, and on drugs and medical care in general. All respondents had personal experience with enema use and were members of the Patient Intelligence Panel. The Medication Adherence Report Scale and Beliefs about Medicines Questionnaire were also used to assess patient responses.Results: Respondents reported overall satisfaction with their last enema use (4.3 on a scale of one to seven, with the main reasons for dissatisfaction being difficulty of administration and pain. Perception of enema convenience was rated 3.3 on average; one-fifth of respondents gave the lowest rating of “very problematic.” Three distinct improvements for enema design were suggested. Respondents were generally neutral or positive in their beliefs on enema medication, but were more neutral to negative in their views of drugs and prescribing in general.Conclusion: Real-life data on the views of patients with inflammatory bowel disease towards enema use are limited. Patients in this study were aware of the importance of adherence with their enema, but mainly did not regard it as convenient or easy to administer, and reported discomfort with enema use. Enema design was deemed by respondents as worth improving, and suggested improvements aimed to

  18. Early colon cancer : findings on double contrast barium enema

    The purpose of this study is to describe the radiologic findings of early colon cancer on double-contrast barium enema. We retrospectively reviewed the double-contrast barium enemas of eight patients (M:F = 6:2; mean age : 67 yrs; range : 48-77 yrs) who were pathologically proven to be early colon cancer. The location, size and gross morphology of lesions was evaluated using double-contrast barium enema, while depth of invasion, degree of differentiation, precancerous lesions and lymph node metastasis were evaluated histopathologically. Early colon cancer was found in the rectum (n=4), sigmoid colon (n=3) and ascending colon (n=1). The size of mass ranged from 2.3 ∼ 8.3 (mean, 4.6) cm. And the polypoid type was most common (n=7); this was subdivided into sessile (Is, n=5), semipedunculated (Isp, n=1) and pedunculated type (Ip, n=1). Another mass was a sessile polypoid combined with a flat depressed lesion. In eight cases, four cancers were confined to the mucosa, while the remaining four had infiltrated the submucosa. Most cancers arose from villous and villotubular adenoma. All cases were well-differentiated adenocarcinoma and no metastasis to lymph nodes had occurred. In early colon cancer, lesions were mainly polypoid and large. Most arose from villous and villotubular adenoma. (author). 19 refs., 1 tab., 3 figs

  19. Self-Administered Ethanol Enema Causing Accidental Death

    Thomas Peterson

    2014-01-01

    Full Text Available Excessive ethanol consumption is a leading preventable cause of death in the United States. Much of the harm from ethanol comes from those who engage in excessive or hazardous drinking. Rectal absorption of ethanol bypasses the first pass metabolic effect, allowing for a higher concentration of blood ethanol to occur for a given volume of solution and, consequently, greater potential for central nervous system depression. However, accidental death is extremely rare with rectal administration. This case report describes an individual with klismaphilia whose death resulted from acute ethanol intoxication by rectal absorption of a wine enema.

  20. Experiences with Cascara-Salax preparating children for barium enema

    30 children prepared for barium enema using Cascara-Salax are reported on. The results are: 1. A satisfactory preparation is possible in out-patient children older than ten years. 2. For children aged 6 to 10 years only the half dose early in the afternoon before the X-ray examination is necessary. 3. In most cases the colon is completely clear, if not, the X-ray study is generally not influenced by rests of stool. 4. It should be considered that other - and often unreliable - cleaning manoevers aren't necessary, the Cascara-Salax - method ist time - saving and side-effects are not of value. (orig.)

  1. Diagnosis and treatment of childhood intussusception using rea-time ultrasonography and saline enema: preliminary report

    Diagnosis and successful reduction of intussusception using realtime ultrasonography and saline enema was reported in 2 cases of ileocolic childhood intussusception. The principle of this saline enema is the same with barium enema in terms of hydrostatic reduction. But barium and fluoroscopy were replaced by warm normal saline and realtime ultrasonography. Characteristic ultrasonographic findings of intussusception prior to and during the saline enema were well demonstrated. Reduction process of intussusception could be traced by real time scan along the course of the colon and successful reduction could be confirmed by ultrasonography alone. Ultrasonographic evidences of successful reduction were loss of echogenic mass with rapid turbulent flow of saline in cecum and absence of target sign in ultrasonography after evaluation of saline. This new method not only is free from radiation exposure and risk of barium peritonitis but also shows characteristic ultrasonographic findings of intussusception as specific as barium enema. Therefore it is expected that hydrostatic saline enema with reatime ultrasonography can replace the barium enema as a treatment of choice of childhood intussusception

    Purpose Anastomotic leakage in colorectal surgery is a very important issue. Although many studies have shown the positive effects of enteral glutamine (Gln) on anastomotic healing, none has assessed the effects of administering Gln via an enema for anastomotic healing. To fill this study gap, this study investigated the intraluminal effect of administration of Gln enema on the healing of colonic anastomosis in a rat model. Methods Thirty Wistar albino rats were divided into three groups containing 10 rats each and were subjected to distal left colon transection and anastomosis. Postoperatively, group I (the control group) was administered no treatment, group II was administered daily placebo enemas containing physiological saline, and group III was administered daily 2% L-Gln enemas. After sacrifice on postoperative day 5, anastomotic healing, burst pressure, tissue hydroxyproline levels, and histological parameters were measured, and group values were compared via statistical analysis. Results Group III was found to have the highest mean bursting pressure and tissue hydroxyproline levels and the lowest mean ischemia score. While the values of these parameters were not found to differ significantly among the groups, the lack of significance may have been due to the limited number of subjects examined. Conclusion Administration of a Gln enema may have a positive effect on anastomosis in terms of bursting pressure and histopathological parameters. Future research should examine administration of a preoperative Gln enema as a means of decreasing the traumatic effects of the enema and identifying its applicability in surgical practice.

  4. Rectosigmoid endometriosis: Comparison between CT water enema and video laparoscopy

    Aim: To evaluate the accuracy of water enema computed tomography (CT) for predicting the location of endometriosis in patients with contraindications to magnetic resonance imaging (MRI), focusing on rectosigmoid lesions and having laparoscopic and histological data as the reference standard. Materials and methods: Thirty-three women (mean age 33.4 ± 3.1 years) suspected of having deep pelvic endometriosis underwent 64-row CT and video laparoscopy within 4 weeks. Two radiologists blinded to the clinical data evaluated the CT images obtained after colonic retrograde distension using water as the contrast medium, and a comparison with laparoscopic and histological findings was performed. CT sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy were calculated. The radiation dose to patients was estimated. Cohen's weighted kappa (κ) test was used to evaluate the interobserver agreement. Results: In 23 out of 33 patients (69%) intestinal implants were found at surgery and pathological examinations. CT confirmed the diagnosis of rectosigmoid endometriosis in 20 out of 23 implants. Three nodules located on the proximal sigmoid colon (two serosal lesions and one infiltrating the muscularis layer) with a diameter of less than 1 cm were not diagnosed. CT sensitivity, specificity, PPV, NPV, and accuracy values were 87, 100, 100, 77, and 91%, respectively. The mean effective dose estimate was 6.30 ± 1.7 mSv. Almost perfect agreement between the two readers was found (k = 0.84). Conclusion: Water enema CT can play a role in the diagnosis of bowel endometriosis and represents another accurate potential tool for video laparoscopic approaches, especially in patients for whom MRI is contraindicated

  5. Sensitivity of single contrast barium enema with regard to colorectal disease as diagnosed by colonoscopy

    The results of single contrast barium enema were retrospectively correlated with colonoscopically diagnosed colorectal disease in 54 patients (75 lesions). Altogether 66 lesions (88%) were correctly diagnosed. The sensitivity of barium enema for polyps was 81% (26/32). There were three perceptive errors and three polyps 5 mm or less in size were not demonstrated by barium enema. Twenty-nine cases of inflammatory disorders were all correctly diagnosed. One of 12 malignancies was missed by perceptive error. In two cases with vascular malformations the barium enema was normal. 4/9 (44%) of missed lesions were perceptive errors and could have been probably avoided by a second independent reading of films.

  7. Colonic diverticulosis: evaluation with double contrast barium enema

    To evaluate the pattern of colonic diverticulosis according to age and sex, and recent trend. The authors retrospectively reviewed 120 cases of colonic diverticulosis in 1,020 patients who had undergone a double contrast barium enema examination between January 1st, 1993, and December 31st, 1995, and analyzed the frequency, size, multiplicity and anatomical site, according to age and sex. Diverticulum size was classified into one of three groups : less than 5mm, 5-10mm, over 10mm in diameter. The overall incidence of colonic diverticulosis was 120 cases among 1,020 patients(11.8%) with an incidence 5.3 times higher in males than in females. Peak incidence was in the fifth decade, with 19 cases (15.8%) among males, and after the sixth decade, with four cases(3.3%) among females. Mean age was 57.7 years. Diverticulum size of 5-10mm in diameter was predominant (2% of cases); average diameter was 5-6mm. The incidence of colonic diverticulosis was 5.1 times more frequent in the right colon (101 cases) than in the left (20 cases). The overall incidence of colonic diverticulosis has continually increased; in addition it has also recently increased slightly in left-sided colon. This is thought to be due to various factors, both congenital and acquired, including longer life with good health care, constipation, irritable bowel syndrome, stress and the tendency of eating patterns to more closely resemble those of the west

  9. Sonography-guided gastrografin enema for meconium plug syndrome in premature newborns: preliminary results

    To evaluate the usefulness of sonography-guided Gastrografin enema for the diagnosis and treatment of meconium plug syndrome in premature newborns in a neonatal intensive care unit (NICU). Fifteen premature newborns underwent 23 sonography-guided Gastrografin enemas on the 8th day of life on average (range: 3 days-21 days). The gestational age and birth weight (mean±standard deviation) of the patients were 29±2 weeks and 999±148 g, respectively. The diagnosis of meconium plug syndrome was based on relevant clinical and radiological findings. Diluted Gastrografin (1:3, 17-45 ml) was administered through a rectal tube under the guidance of sonography until it reached to the cecum. Thereafter, immediate post-procedure and delayed portable abdominal radiographs were taken. All the procedures were done within the NICU. We reviewed the dates of meconium evacuation and the first feeding after the last enema from the clinical data. Radiologically, the timing of the radiographic improvement after the last enema was checked. In cases of distended distal ileum with meconium on preenema sonography, follow-up sonography was performed to determine the interval change after gastrografin enema. None of the sonography-guided Gastrografin enemas performed within the NICU caused procedure-related complications. Meconium was evacuated within one day in all patients. In 14 patients, on average, feeding was started on the 7th day and radiographic improvement was observed on the 3rd day. Four of the five patients showing a distended distal ileum with meconium revealed a decrease in ileal distension on follow-up sonography. On the other hand, the other patient, who did not show such a decrease on follow-up sonography, was found to have ileal stenosis during subsequent surgery. Sonography-guided Gastrografin enema is a safe and effective bedside procedure, when performed in the NICU for the diagnosis and treatment of meconium plug syndrome

Enemas can be very effective but may cause serious adverse events, such as perforation or metabolic derangement. Our aim was to evaluate the outcome of the use of cleansing enema for acute constipation and to assess adverse events within 30 days of therapy. Methods: We performed a two-phase study: an initial retrospective and descriptive study in 2010, followed by a prospective study after intervention, in 2011. According to the results of the first phase we established guidelines for the treatment of constipation in the Emergency Department and then used these in the second phase. Results: There were 269 and 286 cases of severe constipation in the first and second periods of the study, respectively. In the first study period, only Fleet® Enema was used, and in the second, this was changed to Easy Go enema (free of sodium phosphate. There was a 19.2% decrease in the total use of enema, in the second period of the study (P < 0.0001. Adverse events and especially, the perforation rate and the 30-day mortality in patients with constipation decreased significantly in the second phase: 3 (1.4% versus 0 (P = 0.0001 and 8 (3.9% versus 2 (0.7% (P = 0.0001, for perforation and death in the first and second period of the study, respectively. Conclusion: Enema for the treatment of acute constipation is not without adverse events, especially in the elderly, and should be applied carefully. Perforation, hyperphosphatemia (after Fleet Enema, and sepsis may cause death in up to 4% of cases. Guidelines for the treatment of acute constipation and for enema administration are urgently needed. Keywords

  12. Air enema used in the evaluation of acute colitis. A comparison between instant radiography and endoscopy

    Purpose: The purpose of this study was to evaluate air enema as a method of assessing acute colitis. Material and Methods: Twenty-seven patients with symptoms of acute colitis underwent plain abdominal radiography, air enema, and colonoscopy within 48 h. The films were evaluated by 3 observers with different levels of experience, both independently and together, and the results were then compared to the findings at endoscopy. Results: Air enema visualized a greater part of the colon than plain abdominal radiography. When air enema was compared to endoscopy as the reference, it showed good correlation, with a positive predictive value of 92% (sensitivity 62%, specificity 85%). Evaluation of the rectum was less accurate, a finding that emphasized the importance of rigid sigmoidoscopy. Conclusion: Air enema is a useful diagnostic method in acute colitis, it is easily performed and tolerated well with no observed complications. It is also easy to interpret, as shown by a high level of agreement (κ=0.67) among the 3 independent observers with very different levels of experience. (orig.)

  13. Virtual colonoscopy with electron beam CT: correlation with barium enema, colonoscopy and pathology

    To perform virtual colonoscopy using electron beam tomography(EBT) in patients in whom a colonic mass was present, and to compare the results with those obtained using barium enema, colonoscopy and gross pathologic specimens. Materials and Methods : Ten patients in whom colonic masses were diagnosed by either barium enema or colonoscopy were involved in this study. There were nine cases of adenocarcinoma and one of tubulovillous adenoma. Using EBT preoperative abdominopelvic CT scans were performed. Axial scans were then three-dimensionally reconstructed to produce virtual colonoscopic images and were compared with barium enema, colonoscopy and gross pathologic specimens. Virtual colonoscopic images of the masses were classified as either 1)polyploid, 2)sessile,3)fungating, or 4)annular constrictive. We also determined whether ulcers were present within the lesions and whether there was obstruction. Results : After virtual colonoscopy, two lesions were classified as polyploid, one as sessile, five as fungating and two as annular constrictive. Virtual colonoscopic images showed good correlation with the findings of barium enema, colonoscopy and gross pathologic specimens. Three of six ulcerative lesions were observed on colonoscopy; in seven adenocarcinomas with partial or total luminal obstruction, virtual colonoscopy visualized the colon beyond the obstructed sites. In one case, barium contrast failed to pass through the obstructed portion and in six cases, the colonoscope similarly failed. Conclusion : Virtual colonoscopies correlated well with barium enema, colonoscopy and gross pathologic specimens. They provide three dimensional images of colonic masses and are helpful for the evaluation of obstructive lesions

  14. Benefits of Barium Enema in Patients with Incomplete Colonoscopy. Prospective Study of 45 Cases

    To evaluate the usefulness of barium enema in patients with incomplete colonoscopy. There was carried out a prospective 10-month study of 45 patients with incomplete colonoscopy (27 men and 18 women), who were later examined by means of barium enema (33 conventional, 12 double-contrast) in order to check for additional pathology in portions of the colon not visualized by colonoscopy. Barium enema diagnosed six possible additional lesions (13.3%) in portions of the colon not visualized by incomplete colonoscopy (four neoplasia and two non-neoplasia). Regarding the neoplasia two were true positives and two false positives. Both true positives were adenocarcinomas (one synchronous caecum, and another in splenic angle). The two false positives corresponded to fecal matter stuck to the intestinal wall. Regarding the non-neoplasia, multiple stenosis was detected in a patient with Crohn's disease and an enterocolic fistula was found in a patient with sigmoid colon neoplasia. The diagnostic yield of barium enema in the detection of additional pathology in colon portions not visualized by colonoscopy was of 9%. Barium enema following incomplete colonoscopy permits a complete colon evaluation in most cases, and it offers additional diagnostic information. (Author) 21 refs

    1988-01-01

    Necrotizing enterocolitis (NEC) is associated with considerable morbidity and mortality in infants. The diagnosis relies heavily upon radiographic and clinical features. Failure to accurately diagnose NEC is associated with a risk of complications and death, however overdiagnosis also causes both morbidity and mortality as well as excessive medical costs. This report documents the use of barium enema to evaluate suspected clinical or radiographic NEC in 31 premature infants with ambiguous clinical and radiographic signs. The enema was normal in 26 infants and no treatment for NEC was given. Only one of these infants developed signs of NEC subsequent to the examination. Five infants had radiographic evidence of colitis including small ulcerations, spasm, intramural extravasation of barium and mucosal irregularity. Two of the five positive cases are pathologically documented. The barium enema can represent a significant improvement in the specificity of the diagnosis of NEC. Its greatest value is in the exclusion of NEC in ambiguous cases.

  16. The clinical research of the relation between air-pressure enema and the bowel swelling in infantile intussusception

    Objective: To explore the relation of air enema with bowel swelling in' infantile intussusception. Methods: In 61 cases of infantile intussusception, the thickness of the swollen bowel wall was measured and recorded by color Doppler. Then different air pressure was used for enema according to the thickness of the swollen bowel wall. Results: There were 52 (85%) cases succeeded in the operations, with 9 cases (15%) failed.. Thus the standard of feasibility of air-pressure enema in infantile intussusception was as following: (1) When the thickness of the dropsical bowel wall l.5cm, air pressure less than 8 kPa could be used only for diagnosis, not for therapy to prevent gastrointestinal perforation. Conclusion: There is obvious relation between the succession of air-pressure enema with the dropsical degree of bowel wall in infantile intussusception. This standard has very high leading value for the selection of air-pressure enema in infantile intussusception. (authors)

  18. A comparison of radiographer and radiologist reports on radiographer conducted barium enemas

    Purpose: To compare radiographer and radiologist reports on radiographer conducted barium enemas. Method: Two specially trained, experienced radiographers performed barium enemas and prepared provisional reports without consulting radiologists. Later, formal radiologist reports were issued. The reports of each were compared and correlated with clinical findings derived from case note review. Results:Seven hundred and eighty eight patients had barium enemas. Males numbered 295 (37.5%) and females 493 (62.5%). Patients ages ranged from 17 to 95 years (mean 62). The radiologist reported 244 as normal, 432 as diverticular change, 70 with polyps (31 of which had co-existent diverticular disease), 31 with carcinomas and 12 with colitis (three of which had co-existent diverticular disease). Taking the radiologist reports as gold-standard radiographer reports were concordant in 753 (95.5%). There were 35 (4.5%) discordant radiographer reports of these 19 were false-positive diagnoses of polyps and six false positive diagnoses of diverticular change. There were seven false-negative diagnoses of polyps (only one of these was found to have a polyp at follow-up endoscopy). There was one false-negative diagnosis of colitis and two false-negative reports of diverticular change. On follow up there were no false negative diagnoses of carcinoma by either radiographer or radiologist. There was one concordant false-positive diagnosis of carcinoma. Conclusion:Radiographers with specialized training can report barium enemas to a high standard

  19. Barium enema findings (segmental colitis) in four neonates with bloody diarrhea - possible cow's milk allergy

    Four neonates with sudden onset of bloody diarrhea and barium enema findings suggestive of segmental colitis are reported. The infants were not very ill and in all four, the condition was self-limiting. An exact etiology for the condition was not determined but in all of the infants a possible association with cow's milk intolerance was suggested. (orig.)

    A new technique in the preoperative staging computed tomography of rectal cancer using a water enema to promote full distension of the rectum was compared with standard CT in a non-randomised blind study. One hundred and twenty-one patients were enrolled. There were 57 in the water enema CT group and 64 in the standard group. The stage of the disease was assessed following strict criteria and tested against the pathological examination of the resected specimen. Water enema CT was significantly more accurate than standard CT with an accuracy of 84.2% vs. 62.5% (Kappa: 0.56 vs. 0.33: Kappa Weighted: 0.93 vs. 0.84). The diagnostic gain was mainly evident in the identification of rectal wall invasion within or beyond the muscle layer (94.7 vs. 61). The increased accuracy was 33.7% (CL95: 17-49; P < 0.001). The results indicate that water enema CT should replace CT for staging rectal cancer and may offer an alternative to endorectal ultrasound. PMID:8739828

  1. Video disc recording in double contrast barium enema - comparison with conventional fluoroscopy

    The use of electronic radiography in double contrast enema reduced the fluoroscopic area exposure of three different radiologists by 48-63% compared with conventional fluoroscopy. The fluoroscopic technique in video disc recording (VDR) differs from the conventional fluoroscopic technique and therefore the use of VDR requires additional training. (orig.)

  2. Venous barium embolization, a rare, potentially fatal complication of barium enema: 2 case reports

    Venous embolization of barium has been recognized for 4 decades as one of the most dreaded complications of barium enema. Fortunately, the condition is extremely rare. In this report, the radiographic findings in 2 cases of venous embolization (one involving the portal vein and one systematic) are described, and ways to decrease the risk of this complication are discussed.

  3. Revaluation on detection of metastatic cancer of the colorectum with barium enema. Comparison with computed tomography and colonoscopy

    The findings with barium enema were analyzed and compared to those with computed tomography and colonoscopy in 15 patients with metastatic cancer of the colorectum, which were from 8 gastric, 2 colonic, 2 ovarian, 1 pancreatic, 1 prostatic carcinomas and 1 unknown origin. Primary cancers of intra-abdominal cavity origin tended to make multiple colorectal metastases (91.7%). With barium enema colonic and rectal involvement was mostly expressed as the tethered type and the diffuse type by Ishikawa's classification, respectively. Computed tomography detected direct tumor invasion to the colorectum in 4 cases. Of the other 11 cases, 8 patients (72.3%) showed abnormally thickened colorectal wall. Colonoscopy detected only 3 (37.5%) out of 8 lesions seen in 4 patients who had undergone colonoscopy before barium enema. Many of the lesions missed were the tethered type involvement. Barium enema is the most sensitive method to detect metastatic cancer of the colorectum. (author)

    Enema use or douching is a risk factor for HIV/STI in men who have sex with men (MSM). However, few studies have explored enema use practices. We examined the frequency of enema use, type of products used, and reasons to use and not to use before and after receptive anal sex in a large sample of MSM (N = 4,992) recruited from 16 U.S. cities. Through online surveys, we examined personal, behavioral, and environmental factors associated with enema use. Most (52 %) participants reported having douched at least once and 35 % reported douching within the last 3 months. While most (88 %) reported enema use before receptive anal sex, 28 % douched after receptive anal sex. Most participants (65 %) used water to douche, 24 % added salt, soap, and/or antibacterial products to water, and 30 % reported using commercially available products. Being a man of color, HIV-positive, diagnosed with an STI, identifying as "versatile" in sex, and having more than two unprotected sex partners were significantly associated with recent enema use. Douching behavior appears closely associated with HIV/STI risk. Douching with water may be a concern since it may increase HIV/STI infection by damaging the epithelium. Development and promotion of a non-damaging, non-water based enema specifically for use in anal sex are recommended. In addition, the seemingly contradictory recommendations that water-based lubricant is recommended for anal sex but water-based enemas are dangerous need to be reconciled into a single consistent message.

  5. Intra-individual comparison of patient acceptability of multidetector-row CT colonography and double-contrast barium enema

    AIMS: To compare the subjective acceptability of CT colonography in comparison with barium enema in older symptomatic patients, and to ascertain preferences for future colonic investigation. MATERIALS AND METHODS: The study population comprised 78 persons aged 60 years or over with symptoms suggestive of colorectal neoplasia, who underwent CT colonography followed the same day by barium enema. A 25-point questionnaire was administered after each procedure and an additional follow-up questionnaire a week later. Responses were compared using Wilcoxon matched pairs testing, Mann-Whitney test statistics and binomial exact testing. RESULTS: Participants suffered less physical discomfort during CT colonography (p=0.03) and overall satisfaction was greater compared with barium enema (p=0.03). On follow-up, respondents reported significantly better tolerance of CT colonography (p=0.002), and were less prepared to undergo barium enema again (p<0.001). Of 52 subjects expressing an opinion, all preferred CT to barium enema. CONCLUSION: Patient satisfaction was higher with CT colonography than barium enema. CT colonography caused significantly less physical discomfort and was overwhelmingly preferred by patients

  6. Barium enema carried out by digital luminescent radiography (DLR) and conventional screen-film system combinations

    120 double-contrast barium enemas were obtained by both digital luminescent radiography (DLR) and conventional screen-film systems, the digital exposure dose being 50% of the conventional one. In DLR two differently post processed images were obtained from one X-ray exposure: a display with low spatial frequency enhancement was processed to look like a conventional radiograph and was complemented by a display with high spatial frequency enhancement. Analysing the results statistically DLR proved to be diagnostically equivalent to conventional radiography despite the reduction in exposure dose and a slightly diminished image quality. High spatial frequency enhancement did not provide further diagnostic information and is therefore superfluous in barium enemas. (orig.)

    2004-12-01

    About one-half of patients with meconium ileus (MI) present with a complication such as volvulus, atresia, meconium peritonitis or giant cystic meconium peritonitis. The treatment of these complications requires surgery. However, the preoperative diagnosis of complicated MI is difficult. We describe two neonates with complicated small-bowel obstruction, one with MI related to cystic fibrosis and the other not related to cystic fibrosis. In both, contrast enema depicted a spiral appearance of the distal small bowel, which at surgery proved to be the result of volvulus associated with antenatal bowel perforation. This appearance of the small bowel on contrast enema in this clinical setting has not been previously described. The recognition of this spiral appearance of the distal small bowel suggests the need for surgery. (orig.)

CONCLUSÃO: A associação de budesonida com probióticos acelera o trofismo mucoso na colite experimental.

  10. Whipple's disease demonstrated by double contrast small bowel enema with barium and methylcellulose

    The radiologic findings on small bowel enema examination using barium and methylcellulose (SBE+Ba+MC) in a patient with Whipple's disease before and after treatment are described. The changes on SBE+Ba+MC corresponded well to the clinical and morphologic picture. The advantages of this double contrast technique compared to the enteroclysis with barium alone are demonstrated. The SBE+Ba+MC is a good method to demonstrate the manifestations of Whipple's disease involving the small bowel and the mesentery. (orig.)

  11. Radiographer and radiologist perception error in reporting double contrast barium enemas: A pilot study

    Purpose: The practice of radiographers performing double contrast barium enemas (DCBE) is now widespread and in many centres the radiographer's opinion is, at least, contributing to a dual reporting system [Bewell J, Chapman AH. Radiographer performed barium enemas - results of a survey to assess progress. Radiography 1996;2:199-205; Leslie A, Virjee JP. Detection of colorectal carcinoma on double contrast barium enema when double reporting is routinely performed: an audit of current practice. Clin Radiol 2001;57:184-7; Culpan DG, Mitchell AJ, Hughes S, Nutman M, Chapman AH. Double contrast barium enema sensitivity: a comparison of studies by radiographers and radiologists. Clin Radiol 2002;57:604-7]. To ensure this change in practice does not lead to an increase in reporting errors, this study aimed to compare the perception abilities of radiographers with those of radiologists. Methods: Three gastro-intestinal (GI) radiographers and three consultant radiologists independently reported on a selection of 50 DCBE examinations, including the level of certainty in their comments for each examination. A blinded comparison of the results with an independent 'standard report' was recorded. Results: The results demonstrate there was no significant difference in perception error for any of the levels of certainty, for single reporting, for double reading by a radiographer/radiologist or by two radiologists. Conclusions: The study shows that radiographers can perceive abnormalities on DCBE at similar sensitivities and specificities as radiologists. While the participants in the study may be typical of a district general hospital, the nature of the study gives it limited external validity. As a pilot, the results demonstrate that, with slight modification, the methodology could be used for a larger study

  14. Colorectal neoplasm: Magnetic resonance colonography with fat enema-initial clinical experience

    2007-01-01

    AIM: To assess Magnetic resonance colonography with fat enema as a method for detection of colorectal neoplasm. METHODS: Consecutive twenty-two patients underwent MR colonography with fat enema before colonoscopy. T1-weighted three-dimensional fast spoiled gradientecho with inversion recovery sequence was acquired with the patient in the supine position before and 75 s after Gadopentetate Dimelumine administration. Where by, pre and post MR coronal images were obtained with a single breath hold for about 20 s to cover the entire colon. The quality of MR colonographs and patients' tolerance to fat contrast medium was investigated. Colorectal neoplasms identified by MR colonography were compared with those identified on colonoscopy and sensitivity of detecting the lesions was calculated accordingly. RESULTS: MR colonography with fat enema was well tolerated without sedation and analgesia. 120 out of 132 (90.9%) colonic segments were well distended and only 1 (0.8%) colonic segment was poor distension. After contrast enhancement scan, mean contrast-to-noise ratio (CNR) value between the normal colonic wall and lumen was 18.5 ± 2.9 while mean CNR value between colorectal neoplasm and lumen was 20.2 ± 3.1. By Magnetic resonance colonography, 26 of 35 neoplasms (sensitivity 74.3%) were detected. However, sensitivity of MRC was 95.5% (21 of 22) for neoplasm larger than 10 mm and 55.6% (5 of 9) for 5-10 mm neoplasm. CONCLUSION: MR colonography with fat enema and T1-weighted three-dimensional fast spoiled gradientecho with inversion recovery sequence is feasible in detecting colorectal neoplasm larger than 10 mm.

  16. Randomized clinical trial on the use of antispasmodic drugs in barium enema: impact on radiological practice

    Purpose: To assess the willingness of radiologists to change their practice when the results of a randomized clinical trial (RCT) on the use of antispasmodic drugs in barium enema are presented. Materials and Methods: During the years 1994 and 1995 two postal questionnaires were sent to 481 practicing radiologists who were all members of the Netherlands Society of Radiology. In the first questionnaire the respondents were asked to give the characteristics of their practices in performing daily barium enema. The data from this questionnaire was used as a reference. The second questionnaire was sent to the respondents together with an abstract on the randomized clinical trial supporting the use of antispasmodic drugs in barium enema. We also indicated a preference for Buscopan over Glucagon as the antispasmodic drug. The willingness to change prescription habits was measured by comparing the data of the two questionnaires. Results: Of 481 practicing radiologists, 312 responded to the first questionnaire and gave information of their prescription habits (response rate 64%). These 312 responders were sent an abstract of the RCT and were asked to fill out a second questionnaire to determine their willingness to change their practice. Two hundred and sixty-seven radiologists responded (response rate 86%). A significant number of 119 (51%) were willing to increase the use of antispasmodic drugs. A significant number of 128 (55%) chose to increase the use of Buscopan, while a significant number of 81 (32%) were willing to decrease the use of Glucagon. Conclusion: Direct exposure to the results of an RCT recommending the use of antispasmodic drugs in barium enema, especially Buscopan, is likely to increase its use by practicing radiologists

    2014-06-01

    We report the case of a 58-year-old woman who was referred to our hospital due to frequent bloody mucus diarrhea. She was diagnosed with cap polyposis based on typical endoscopic and histological findings. Colonoscopy revealed multiple, reddish, mucus-capped polypoid lesions from the rectum to the sigmoid colon. A pathological examination revealed that the polyps were covered by erosive and inflamed granulation tissue with decreased crypt cells. Laboratory data indicated positive values for Helicobacter pylori immunoglobulin G antibody and hypoproteinemia. Metronidazole, H. pylori eradication, and levofloxacin therapies were not effective; however, the subsequent administration of betamethasone enema dramatically improved the clinical symptoms and endoscopic findings. The hypoproteinemia was normalized after the therapy. The dose of the betamethasone enema was tapered gradually, and no recurrence was observed 6 months after discontinuation of the treatment. This case suggests that betamethasone enema may be considered as the second treatment choice for cap polyposis patients after H. pylori eradication, metronidazole or levofloxacin therapy.

  18. Factors influencing the detection of abnormalities in barium enemas performed by junior radiologists

    Aim: To study the effects of patient variability, technical examination and radiologist-related factors on the radiological diagnosis of barium enema studies. Materials and Methods: Twenty-one residents (12 women and nine men, age 26-39 years) performed 523 double contrast barium enemas in a university hospital. Diagnoses were classified as normal (n=203), diverticulosis (n=224), polyps (n=25), tumours (n=20) and other (n=46); five were missing diagnoses. Binary and multinomial logistic regressions were used to study the relations between the independent variables and the radiological diagnoses. Results: Patients' advanced age (p<0.001) and obesity (p=0.041) were significant positive predictors for the detection of any abnormalities, as was good or moderate study quality (p=0.023). However, patients' obesity was negatively associated with the detection of polyps (p=0.037). Pathological findings were associated with higher dose-area products (p=0.047) than normal cases. Residents' advanced age (p=0.029) and experience (a high number of previously performed barium enemas; p=0.009) were negative predictors for the detection of pathological findings. Conclusion: Patients' obesity hampers polyp detection, possibly due to decreased image quality or coexisting diverticula. The most experienced and oldest residents missed positive findings, possibly due to insufficient consultation of supervising radiologists, emphasizing the need for their optimal cooperation

  19. THE BENEFITS OF IVP AND BARIUM ENEMA IN PATIENTS UNDERGOING HYSTERECTOMY FOR BENIGN CONDITIONS

    1995-06-01

    Full Text Available A review of500 cases was undertaken in order to identify which patients undergoing hrsterectomy for benign disease weresubjected topreoperative intravenous pyelogram (lVP and/ or barium enema (BE, and what abnormalities couldbe anticipatedbythese procedures as a surgical screen."nOver 80% ofthe cases reviewed underwent trans-ahdominal hysteredomy, and the remainder hadvaginal hysterectomy. Close to one-third of the patients were admitted with the diagnosis offibroid; and one-sixth with uterine prolapse. Miscellaneous benign conditions included adnexal masses, ovarian cysts, and dysfunctional uterine bleeding. Twentytwo patients (4.4% had IVP preoperatively, while eight patienls (1.6% were given both lIP and barium enema prior to hysterectomy. Over three-fourth ofthe 22 patients revealed normal IVP, while one-half who had received both IVP and/or BE had an unremarkable roentgenogram interpretation. None of the subiects who had unusual findings in either group were ofclinical significance on the pathology report Post-operative coursefor the patients was also quite unremarkable. This review indicates that when benign disease is clear-cut and hysteredomy is indicated there is no needfor IVP and barium enema.

    To evaluate the usefulness of barium enema in patients with incomplete colonoscopy. There was carried out a prospective 10-month study of 45 patients with incomplete colonoscopy (27 men and 18 women), who were later examined by means of barium enema (33 conventional, 12 double-contrast) in order to check for additional pathology in portions of the colon not visualized by colonoscopy. Barium enema diagnosed six possible additional lesions (13.3%) in portions of the colon not visualized by incomplete colonoscopy (four neoplasia and two non-neoplasia). Regarding the neoplasia two were true positives and two false positives. Both true positives were adenocarcinomas (one synchronous caecum, and another in splenic angle). The two false positives corresponded to fecal matter stuck to the intestinal wall. Regarding the non-neoplasia, multiple stenosis was detected in a patient with Crohn's disease and an enterocolic fistula was found in a patient with sigmoid colon neoplasia. The diagnostic yield of barium enema in the detection of additional pathology in colon portions not visualized by colonoscopy was of 9%. Barium enema following incomplete colonoscopy permits a complete colon evaluation in most cases, and it offers additional diagnostic information. (Author) 21 refs.

    Background The few studies on MR colonography with air enema involved feasibility of bowel distention and imaging quality and lacked detection sensitivity of colorectal neoplasms. The purpose of this prospective study was to assess the detection sensitivity of colorectal neoplasms with the three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography with air enema.Methods A total of 30 patients scheduled for optical colonoscopy due to rectal bleeding, positive fecal occult blood test results or altered bowel habits were recruited and successfully underwent entire colorectal examinations with three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography and subsequent optical colonoscopy on the same day. Detection sensitivity of colorectal neoplasms with MR colonography was statistically analyzed on a per-neoplasm size basis by using findings from optical colonoscopy and histopathological examinations as the reference standards.Results Seventy-six neoplasms were detected with optical colonoscopy, consisting of 1 mm-5 mm (n=11), 6 mm-9 mm (n=29) and >10 mm (n=36) in diameter. Detection sensitivities of 1 mm-5 mm, 6 mm-9 mm, ≥10 mm and >6 mm colorectal neoplasms with MR colonography were 9.1%, 75.9%, 100% and 89.2%, respectively; overall detection sensitivity for all sizes colorectal neoplasms was 77.6%.Conclusions Detection sensitivity of three-dimensional Fourier transform fast spoiled gradient-recalled MR colonography with air enema is low for 1 mm-5 mm colorectal neoplasms, but the detection sensitivity is 89.2% for ≥6 mm neoplasms, and all ≥10 mm neoplasms could be detected.

    1997-02-01

    Questionnaires were sent to all Consultant Radiologists in the UK regarding complications from barium enema examinations. The 756 respondents performed a total of 738,216 examinations over the three year period 1992 to 1994. Seventy-seven Consultants (10.2%) reported a total of 82 complications including 13 deaths: an overall mortality rate of 1 in 56,786. Only three of 30 (10%) cases of bowel perforation died, as compared with nine out of 16 (56%) cases of cardiac arrhythmia. The only remaining death was a consequence of vaginal intubation. Details of all the reported complications are recorded. This was an entirely retrospective study. PMID:9043049

  4. Limitations of combined flexible sigmoidoscopy and double contrast barium enema in patients with rectal bleeding

    Eighty-seven outpatients with non-massive rectal bleeding or asymptomatic positive fecal occult blood were evaluated with 35 cm flexible sigmoidoscopy, double contrast barium enema (DBCE) and colonoscopy. 82% had hemorrhoids and 35% harbored colorectal neoplasia. The combination of flexible sigmoidoscopy and DCBE missed none of 7 malignant lesions. However, 35% of benign polyps ≥ 1 cm and 60.5% of those < 1 cm were not detected by this combination. The presence of hemorrhoids should not prevent a search for colon neoplasia and colonoscopy is the preferred method. (orig.)

    2007-01-01

    Post-operative complications of colorectal surgery occur not uncommonly. They have to be detected as early as possible, in order to reduce their morbidity and mortality rates. The most frequent early complications are abscesses, mechanical obstruction, and anastomotic leak. Imaging studies are required in order to assess such complications. We present a case for which radiological procedures were contributive for an optimal diagnosis of anastomotic leak following colo-rectal anastomosis. We emphasize the role of conventional radiology (contrast enema) combined with CT in the post-operative detection of an anastomotic intestinal leak. PMID:18376770

  6. Early manifestation of Yersinia colitis demonstrated by the double-contrast barium enema

    Aspestrand, F.

    1986-11-01

    A 19-year old female with a bloody, diarrheal illness of acute onset where Crohn's disease primarly was suspected is presented. The double-contrast barium enema revealed multiple, diffusely scattered aphthous erosions of the colonic mucosa: the rectum was scarcely affected. Biopsies taken by endoscopy demonstrated nonspecific inflammatory changes of the mucous membrane. However, routinely taken stool cultures revealed an infectious colitis due to Yersinia enterocolitica. Our case demonstrates the necessity to consider Yersinia enterocolitis in the radiographic differential diagnosis when the diagnosis of Crohn's disease or ulcerative colitis seems obvious.

    Ribault, L; Carli, P; Gabet, J; Martet, G; Gournier, J P

    1988-11-01

    The rectal administration of irritant substances can induce lesions which do not regress after removal of the cause. More or less severe and more or less extensive stenoses have been reported in the literature. The authors report a case of very extensive and very tight rectosigmoid stenosis developing after potassium enema administered to a chronically constipated 26 year old African woman with limited rectal stenosis of unknown origin. Rectosigmoid and left colonic resection with trans-anal recto-colonic anastomosis gave this patient normal intestinal transit and good faecal comfort. PMID:3225277

  9. Clinical and Experimental Study on Treatment of Infantile Autumn Diarrhea by Retention Enema with Qilian Liquid (

    2001-01-01

    :Objective:To find out the effective treatment for infantile autumn diarrhea(IAD).Methods:Retention enema with Qilian Liquid(QLL) was applied to 106 patients of IAD with positive antigen of rotavirus in stool,and the result in the treated group was compared with that in the control group(82 patients) in aspects of clinical effect, negative conversion rate of rotavirus in stool and change of serum immunoglobulin. Animal experimental study was also conducted.Results:The disappearance time of principal symptoms, negative conversion rate of rotavirus in stool and serum levels of IgA and IgG in the treated group were significantly better than those in the control group (P<0.01, P< 0.05). Experimental study showed that QLL not only has the anti-viral effects to stop diarrhea, but also has effects in enhancing immune function and protecting intestinal mucous membrane. Conclusion:Retention enema with QLL is an effective therapy for the treatment of IAD.

  10. Effect of glucagon on the diagnostic accuracy of double-contrast barium enema examinations.

    Thoeni, R F; Vandeman, F; Wall, S D

    1984-01-01

    The effect of glucagon-induced hypotonicity on the diagnostic accuracy of double-contrast barium enema examinations was determined in 133 consecutive patients in a double-blind crossover study. All patients underwent colonoscopy and served as their own controls by undergoing a double-contrast study after intravenous injection of 1 mg of glucagon and another after intravenous injection of 1 ml of saline placebo, in randomized order. The frequencies of good/excellent hypotonicity and quality of examinations after first doses of glucagon (55.3% and 80.8%) were not significantly different from the frequencies of good/excellent results after first doses of saline (51.3% and 86.5%). The sensitivity was 72.6% after glucagon and 64.5% after placebo; the specificity was 88.7% after glucagon and 77.9% after placebo; and the respective accuracies were 81.2% and 71.9%. These percentages should be used only to compare results with and without glucagon and, by study design, do not represent results of a complete double-contrast study. The variation among these percentages was not statistically significant, but diverticulitis was more accurately diagnosed after glucagon. It was concluded that glucagon does not significantly improve the sensitivity and specificity of the double-contrast barium enema examination and should be used only in selected instances.

    2003-04-01

    AIM: To evaluate the efficacy of peppermint oil in barium as a spasmolytic agent during a double-contrast barium enema (DCBE). MATERIALS AND METHODS: A total of 383 DCBEs with positive results from occult blood tests were assessed. Patients were assigned to one of four groups: peppermint in barium (n=91), peppermint in tube (n=90), Buscopan (n=105), or no treatment (n=97). After a screening sigmoidoscopy, the DCBEs were performed using air as a distending gas. In the Buscopan group, the DCBE was performed with an intramuscular injection of 20 mg Buscopan at the start of the examination. Patients in the no-treatment group underwent DCBE without any spasmolytic agent. A peppermint oil preparation (30 ml) was mixed in the barium solution for patients in the peppermint-in-barium group, and the same dose of peppermint oil was included in the enema tube in the peppermint-in-tube group. The presence of spasm on a series of spot films was evaluated without information about the type of spasmolytic agent used. RESULTS: The percentage of patients in the four groups (no treatment, Buscopan, peppermint in tube, and peppermint in barium) with absence of spasm in the entire colon on the series of spot films was 13.4, 38.1, 41.8, and 37.8%, respectively. In the group using peppermint oil or Buscopan, the rate of patients with non-spasm examination was higher than that in no-treatment group (p<0.0005). Peppermint oil had the same spasmolytic effect as the systemic administration of Buscopan in the transverse and descending colon. Peppermint oil had a stronger effect in the caecum and the ascending colon than a Buscopan injection (p<0.005). There was no advantage to placing peppermint oil in the enema tube over mixing it in the barium solution. A total of 157 polyps were found during the DCBE procedures, and no differences were observed in the number of lesions among the four groups. Peppermint oil did not impair image quality. CONCLUSION: Barium solution mixed with peppermint oil

  13. Comparison of Golytely lavage with standard diet/cathartic preparation for double-contrast barium enema.

    Girard, C M; Rugh, K S; DiPalma, J A; Brady, C E; Pierson, W P

    1984-06-01

    In a two-part study, two groups of 100 outpatients each were randomly assigned a colon preparation. In part 1, a standard 1-day diet/cathartic combination was compared with Golytely. In part 2, diet/cathartics was compared with Golytely plus Dulcolax (bisacodyl). The standard preparation provided good or excellent feces removal in 81 (80%) of 101 subjects. Golytely alone was successful in only 21 (53%) of 40 patients, but Golytely followed by Dulcolax achieved good or excellent feces removal in 31 (82%) of 38. Degraded mucosal coating with Golytely alone, due to excessive fluid retention, was also corrected by the addition of Dulcolax. Golytely alone is not an adequate method of colon cleansing for double-contrast barium enema, but Golytely plus Dulcolax is as effective as the standard preparation. PMID:6609598

  14. Choice of double contrast barium enema (DCBE) method based on patient exposure dose

    Morbidity of colon cancer continues to increase, taking second and third places in malignant tumors. The incidence of colorectal cancer (CRC) increases exponentially with age; those over 50 years of age represent 37% of general population, yet account for 95% of the cases, and more than 96% of the deaths from colon malignancies For a long time radiologic examinations were considered as a main pre-operative diagnostic method for cancer of the colon. The sensitivity of the barium enema with regard to diagnosis of the carcinoma and polyps ranges from 92-98.5%. Sigmoidoscopy for detection and removal of polyps has been shown to decrease the incidence of subsequent CRC's by 70-80% in distal colon. However, the sigmoid colon is often difficult to examine because of associated diverticular disease, and about 15% of tumors in the sigmoid colon are overlooked. Authors)

  15. Ischaemic colitis: Diagnostic evaluation by means of contrast enema and CT

    The abdominal plain radiograph reveals a tympanous colon, loss of sacculation, gas in the colon wall (pneumatosis coli), or free air (incase of perforation), indicating ischaemic processes and possible subsequent complications. In the contrast enema (made with aqueous iodine contrast medium), the oedema caused by ischaemic processes in the mucosa or submucosa can be perceived as thumb prints. A serrate image of the mucosa indicates necrosis; antimesenterial sacculations are signs of a deep lying intestinal wall necrosis including the risk of perforation. The CT is able to show in addition to the sacculations ischaemia-induced thickening of the intestinal wall. Another advantage of CT is that the surrounding tissue can be assessed at the same time, and extra-mural complications such as an abscess or air in the portal vein are revealed, which may indicate an ischaemic process deep in the intestinal wall accompanied by bacterial infiltration.

  16. Intestinal preparation for colon enema with fosfo-soda fleet versus the conventional method

    The authors evaluate the possible optimization of a well-tolerated and versatile method of intestinal preparation able to adequately free the lumen and consequently improve diagnostic results with a lower risk of prolonged hospital stay for incorrectly prepared patients. They examined 40 patients, namely 20 men and 20 women referred to the Institute of radiology of the 'Sacro Cuore' Catholic University of Rome (Italy), Gastrointestinal tract unit, to undergo double contrast colonic enema. The statistical analysis of all data was performed with Wilcoxon test. Intestinal preparation with fosfo-soda fleet appeared to be definitely better than the conventional method relative to tolerance, while providing similarly satisfactory data relative to the other parameters

    Abstract Background and Aims The standard whole-colon tests used to investigate patients with symptoms of colorectal cancer are barium enema and colonoscopy. Colonoscopy is the reference test but is technically difficult, resource intensive, and associated with adverse events, especially in the elderly. Barium enema is safer but has reduced sensitivity for cancer. CT colonography ("virtual colonoscopy") is a newer alternative that may combine high sensitivity for cancer with safety and patien...

  19. Comparison of Sucralfate and Hydrocortisone Enemas in Treatment of Active Ulcerative Proctitis; A Double-Blind Randomized ClinicalL Trial

    2003-08-01

    Full Text Available Sucralfate enema has been proposed and investigated in treatment of ulcerative proctitis, but its efficacy is still a matter of debate. Hydrocortisone enema is still an established drug in treatment of ulcerative proctitis. This study was designed to compare the effect of sucralfate enema with hydrocortisone enema. Patients with active sigmoidoscopic and histologic features of ulcerative proctitis were included. All patients had clinical manifestations of proctitis for at least four weeks prior to the study and had negative parasitic stool culture. The total of 25 patients entered the study. They were randomly divided in two groups; group I (n =14 and group II (n = 11 who received sucralfate and hydrocortisone enemas respectively for 4 weeks. Both groups had a significant improvement in clinical features, histologic activity and sigmoidoscopic evaluation in comparison with the baseline. Furthermore there was no significant differences between the two groups concerning mean changes of clinical, sigmoidoscopic, and histologic grading, after treatment. Considering the low cost and minimal adverse effects of sucralfate, and almost equal efficacy in comparison with hydrocortisone enema, its usage can be recommended.

  20. An oral modified-release nifedipine tablet (Adalat LA) and its appearance on double contrast barium enema

    Adalat LA 30 mg and 60 mg tablets are widely prescribed oral modified release nifedipine preparations with a porous, non-digestible plastic tablet coating which is required in order to effect the osmotically driven slow release mechanism. These tablets may therefore be seen anywhere along the gastrointestinal tract and are passed apparently whole in the faeces. An example of the appearance within the rectum of Adalat LA 30 (Bayer) on double contrast barium enema is shown and the main features described. A review of the literature is given. Recognition of the appearances during the barium enema examination will prompt those performing the procedure to question the drug history where relevant and will reduce the incidence of false-positive reporting.

  1. Hereditary nonpolyposis colorectal cancer: not just a barium enema! Radiographic manifestations and screening tools

    Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant trait characterized by presentation of colorectal cancer (CRC) at an early age and by an increased risk of other primary malignancies, including those of the endometrium. ovaries, stomach, small bowel, upper biliary tract, skin, and brain, as well as by transitional cell carcinoma (TCC) that especially involves the renal pelvis and ureter. Because specific genetic mutations causing HNPCC have been recently discovered, genetic screening options have been developed for some families. Subsequently, radiology has an increasing role in surveillance for and management of these HNPCC-associated tumours. Although colonoscopy is the mainstay of a screening regimen for colon cancer, the barium enema has been a standard radiologic investigation. Further, computed tomography (CT) colonography (now practised in various centres) will, with further refinement, prove to be of increasing value. Ultrasonography is a standard investigation for endometrial and ovarian cancer, with CT and magnetic resonance (MR) imaging often playing a central role. As for TCC, intravenous urography (IVU) had been a standard investigation tool. However, with continued evolution of multidetector row CT with postprocessing manipulation (CT urography [CTU]), the role of IVU is diminishing in most centres. Newfoundland has a high prevalence of HNPCC exhibiting a broad range of manifestations. In this article, radiologic images of various tumours from individuals with HNPCC demonstrate a radiologic spectrum of this fascinating hereditary disease. Screening implications and specific screening methods are reviewed. (author)

    To evaluate prospectively the effect of sodium butyrate enemas on the treatment of acute and the potential influence on late radiation-induced proctitis. 31 patients had been treated with sodium butyrate enemas for radiation-induced acute grade II proctitis which had developed after 40 Gy in median. During irradiation the toxicity was evaluated weekly by the Common Toxicity Criteria (CTC) and subsequently yearly by the RTOG (Radiation Therapy Oncology Group) and LENT-SOMA scale. 23 of 31 patients (74%) experienced a decrease of CTC grade within 8 days on median. A statistical significant difference between the incidence and the severity of proctitis before start of treatment with sodium butyrate enemas compared to 14 days later and compared to the end of irradiation treatment course, respectively, was found. The median follow-up was 50 months. Twenty patients were recorded as suffering from no late proctitis symptom. Eleven patients suffered from grade I and 2 of these patients from grade II toxicity, too. No correlation was seen between the efficacy of butyrate enemas on acute proctitis and prevention or development of late toxicity, respectively. Sodium butyrate enemas are effective in the treatment of acute radiation-induced proctitis in patients with prostate cancer but have no impact on the incidence and severity of late proctitis.

    Introduction A targeted Hirschsprung disease (HD) diagnostic is necessary, as it determines a specific approach primarily based on surgical resection of the affected aganglionic colonic segment. The aim of this study was to evaluate the diagnostic accuracy of a contrast enema (CE) for HD diagnosis and to determine whether it should be performed before or after rectal biopsies (RBs). Methods A retrospective observational study of children undergoing RB for HD investigation was performed. In the performed CE, the occurrence and the level of a colonic caliber change (CCC) were recorded and its concordance with the histologically assessed level of aganglionosis by RB and the odds ratio were calculated. Results A total of 107 cases were included. Sensitivity and specificity for a CCC in CE were 74.1% and 94.6%. A CCC present in CE was associated with a 50-fold increased probability for a histologically proven HD. The overall concordance between a CCC and the histologically assessed level of aganglionosis was high (kappa 0.642, p = 0.003), being correct in 94.4% of cases when the CCC was located in the rectosigmoid, but only in 50% of cases when it was located in more proximal segments. By performing a CE only after HD diagnosis confirmation by RB would avoid 67.5% of CE with no loss of diagnostic accuracy. Conclusion We confirm that CE is a valuable tool for HD diagnosis; however, it should only be performed for subsequent diagnostic and surgical planning following histological confirmation of HD by RB. On the basis of this, an algorithm for an optimized investigation and management of HD is presented. PMID:25803244

    2005-01-01

    Ten new rare earth solid complexes were synthesized by the reaction of sodium 5-aminosalicyliate with rare earth chloride. The structure character, physical and chemical properties of these complexes were studied by IR, UV, 1H NMR spectra, TG-DTA, fluorescence, elemental analyses, molar conductance and magnetic susceptibility. The ten rare earth complexes exist in dimeric form probably and the coordination number is seven. The antibacterial activity of the ligand and six complexes was also tested against Staphylococcus aureus, Escherichia coli and Bacillus subtilis, and the effect of Yb complex at 20 mg·ml-1 against Staphylococcus aureus is most significant.

    2004-01-01

    Early studies from tertiary referral centers in the United States and Europe showed that patients with long-standing and extensive inflammatory bowel disease (IBD) have an increased risk of colon cancer. It was subsequently appreciated that the degree of risk depended on the population being studied and on both genetic and environmental factors (eg diet, drugs and prior surgical treatment). Indeed, over the past decade or so, the effects of chronically administered medications, including 5-am...

    Full Text Available OBJETIVO: Verificar, retrospectivamente, a prevalência do refluxo cecoileal diagnosticado pelo enema opaco, caracterizar sua distribuição etária e sexual e classificá-lo conforme o grau de intensidade. MATERIAIS E MÉTODOS: Foram revistos 715 enemas opacos, incluindo 268 homens e 447 mulheres com idade média de 54 anos. RESULTADOS: Dos 715 casos examinados, 46,5% apresentaram refluxo cecoileal, sendo 45% do tipo leve, 37,5% do tipo moderado e 17,5% do tipo severo. Refluxo cecoileal esteve presente em 48,3% das mulheres e em 43,6% dos homens. A distribuição percentual do refluxo cecoileal por faixa etária mostrou 46,1% nos indivíduos com menos de 21 anos, 42,1% nos indivíduos entre 21-40 anos, 49,8% nos indivíduos entre 41-60 anos e 44,7% nos indivíduos com mais de 60 anos. CONCLUSÃO: Refluxo cecoileal foi achado relativamente freqüente em nosso material, correspondendo os graus moderado e severo a 25% do material examinado. Aparentemente, não há associação entre seu surgimento e sexo ou idade. A etiopatogenia e conseqüências do refluxo cecoileal são ainda pouco conhecidas. Alguns estudos sugerem que o comprometimento de componentes da junção ileocecal, como os ligamentos, pode favorecer seu aparecimento. Entre as conseqüências prováveis, incluem-se a contaminação e alteração motora ileais, resultantes do material refluído do ceco.OBJECTIVE: Retrospectively determining the coloileal reflux prevalence at the barium enema examination, characterizing its distribution by sex and age range and classifying it according to the intensity degree.

  8. Correlation of double-contrast high-density barium enema, colonoscopy, and histology in children with special attention to disparities

    Colonscopic and double-contrast high-density barium enema (DCBE) findings were correlated in 68 patients (39 boys and 29 girls) aged 6 months to 18 years (mean 11.6 years) evaluated over a 24-month period. There was excellent correlation in 53 patients (78.0%) and good correlation in another 3 (4.4%) who had identical diagnoses and only slightly differing extent of disease reported. In 2 of these, DCBE showed more extensive disease, confirmed histologically in 1. Distal colitis seen on colonoscopy as reddening and neovascularity was missed on DCBE in 6 patients. Colonoscopy and DEBE failed to show a polyp in 1 patient each. One patient who had a normal DCBE and colonoscopy demonstrated a histological abnormality, and 1 patient with an abnormality on histology and DCBE was normal on colonscopy. A disparity resulted from the time between procedures in 1 patient and observer error in another. This high correlation is far better than any previously reported in children, supporting the use of high-density barium sulfate and double-contrast barium enemas in pediatric patients. (orig.)

    Among the many inflammatory diseases of the colon, Crohn`s disease and ulcerative colitis occur most frequently. For primary evaluation, endoscopy has widely replaced the barium enema (BE) as diagnostic method. BE, however can provide important additional informations in the differential diagnosis of chronic inflammatory colonic diseases. Purpose of this article is the demonstration of typical, but also of atypical radiological changes in different stages of Crohn`s disease and ulcerative colitis, as well as calling attention to the importance of CT. A BE demands a refined examination technique using double contrast. All CT-examinations have to be scrutinized for changes of the bowel and mesentery. A dedicated spiral-CT examination might be indicated in a known disease in order to obtain special information. The advantage of a BE over endoscopy is a clear and reproducible demonstration of the patterns of distribution and character of the disease as well as the detection of fistulae. The classification into one or the other disease entity can be better accomplished. CT is superior in detecting bowel wall thickening, extraintestinal disease and complications. In diagnostic imaging of chronic inflammatory bowel diseases, endoscopy and radiologic techniques are used complementarily. (orig.) [Deutsch] Unter den vielen entzuendlichen Dickdarmerkrankungen sind Morbus Crohn und Colitis ulcerosa bei weitem am haeufigsten. Die Endoskopie hat den Kolonkontrasteinlauf (KE) in der Primaerdiagnostik weitgehend abgeloest.

    Full Text Available Ek kustha is a type of kshudra kustha described in different Ayurvedic classics. It is a vata-kaphaj disorder. The clinical symptom of Ek kustha described in Ayurveda resembles with the clinical symptom of Psoriasis. The clinical feature of Ek kustha described by Kashyap represents remission, relapse and seasonal variation, which are present in Psoriasis. Psoriasis like other skin disorders is challenge to the medical sciences. In modern medicine there is no definite treatment for this disease. The medicines, which are available to treat the disease, are not very effective and cannot be used for long-term management because of their local and systemic side effect as well as toxicity. Medicines, which are used in Ayurveda, are safe and being practiced since thousands of year. A large number of drugs and measures are described in Ayurveda for the treatment of Kustha. This study was designed to access the anti-inflammatory activity of Basti Therapy (Medicated Enema in the treatment of Ek kustha (psoriasis. The study was randomized open phase clinical trial. Basti planned for the therapy was Yoga-basti Karma in which Anuvasana basti was given using Mahanarayan tail while Niruh basti was given using Dashmula quath in accordance with Aharya Charak as mentioned in Siddhi Sthana 1/25. Keeping this view in mind we have started basti therapy in the patients of osteoarthritis and found encouraging results. The patients of age group 18 to 60 were selected on the basis of Ayurvedic signs and symptoms of Ek kustha. Observations were recorded for sharply defined erythemo-squamous lesions varying in size; presence of erythema, scaling and induration in the lesions; surface consists of non-coherent scales; positive Auspitz sign – (Bleeding occurs after scratching of scales; positive onion peeling sign/candle grease sign (after scratching the scales fall like peels of onion. The laboratory values of TLC, DLC, ESR and CRP were also recorded before and after the

    The aims of the study are to demonstrate the effect of probiotic use on the healing of radiation proctitis (RP) and evaluate the efficiency of fecal biomarkers at follow-up of the treatment. Thirty-two male/female rats were randomly separated into four groups of eight rats. The first group (control) was not radiated. RP was created by 17.5 Gy single dose rectal irradiation. The second group (RP) was subjected to RP, but not treated. The third group (RP+ASA) was treated with 5-aminosalicylic acid (5-ASA) 250 mg/kg daily by gastric lavage for 14 days after the irradiation, and the forth group (RP+LGG) was treated with Lactobacillus GG (LGG) 25 × 100 million CFU daily. Feces samples were taken at the 7th and 14th day of the treatment for fecal biomarkers. Rectums of the rats were resected at the 14th day by laparotomy. Samples were evaluated both macroscopically and microscopically. RP was achieved both macroscopically and microscopically. Weight loss of RP group is statistically significant (p < 0.005) than other groups. The healing ratio of RP+ASA and RP+LGG groups was significantly better than the RP group (p < 0.005) both macroscopically and microscopically. But there was no significant difference between ASA and LGG groups. Biochemically, fecal calprotectin was found to be more effective than fecal myeloperoxidase and fecal lactoferrin to show the efficacy of treatment of radiation proctitis. The results of our study demonstrate that probiotic is as effective as 5-aminosalicylic in the treatment of radiation proctitis, and fecal calprotectin is a useful biomarker in determining the response to the treatment.

Megacolon is one of its consequences that has not been classified as megaesophagus is. Our objective was to evaluate the results of contrast enemas of patients with Chagas' megacolon, in order to establish a practical radiologic classification of the disease's stage. METHODS: The authors evaluated 76 contrast enemas of patients with Chagas' megacolon and 59 enemas of normal patients. In those x-rays were measured the transversal diameters of sigmoid by the level of an imaginary line that passes between iliacs crests. The distribution of these measurements was analyzed establishing a classification into three grades (1 to 3. RESULTS: Fifty-two patients, without megacolon, had

  13. Audit in action: significant reduction of double-contrast barium enema screening time with no loss of examination quality

    The double-contrast barium enema is an examination of high patient exposure. As part of a departmental audit, the authors' fluoroscopic screening times were recorded. A study was undertaken to see if a determined effort could reduce screening time without having a detrimental effect on the quality of examination. Methods of screening time reduction were identified and implemented by two radiologists. Before the study average screening time for radiologists A and B was 2.6 min and 3.2 min, respectively (over 56 examinations). After changes, the average screening time for both was 0.9 min (over 50 examinations). This is a statistically significant reduction (p<0.01). Examinations were assessed independently by a gastroradiologist. No difference in quality of the examinations was identified. (author)

    A double blind prospective study was undertaken to evaluate the benefit of using carbon dioxide in double contrast barium enema (DCBE). 142 consecutive patients referred for DCBE were randomly allocated to receive either air or carbon dioxide (CO2) as the insufflation agent. The use of CO2 reduced the incidence of immediate and delayed severe pain from 31% to 12.5% and from 12.9% to 4.2% respectively. There was a statistically significant higher incidence of delayed severe pain in the younger age group as found in previous studies. Post-evacuation films showed that there was less residual gas after CO2. The quality of the DCBE was unchanged. We urge the more widespread use of CO2 as insufflation agent in DCBE. PMID:8472110

    To evaluate the effects of rectal enemas on rectal doses during postoperative high-dose-rate (HDR) vaginal cuff brachytherapy (VCB). This prospective trial included 59 patients. Two rectal cleansing enemas were self-administered before the second fraction, and fraction 1 was considered the basal status. Dose-volume histogram (DVH) values were generated for the rectum and correlated with rectal volume variation. Statistical analyses used paired and unpaired t-tests. Despite a significant 15 % reduction in mean rectal volume (44.07 vs. 52.15 cc, p = 0.0018), 35.6 % of patients had larger rectums after rectal enemas. No significant rectal enema-related DVH differences were observed compared to the basal data. Although not statistically significant, rectal cleansing-associated increases in mean rectal DVH values were observed: D{sub 0.1} {sub cc}: 6.6 vs. 7.21 Gy; D{sub 1} {sub cc}: 5.35 vs. 5.52 Gy; D{sub 2} {sub cc}: 4.67 vs. 4.72 Gy, before and after rectal cleaning, respectively (where D{sub x} {sub cc} is the dose to the most exposed x cm {sup 3}). No differences were observed in DVH parameters according to rectal volume increase or decrease after the enema. Patients whose rectal volume increased also had significantly larger DVH parameters, except for D{sub 5} {sub %}, D{sub 25} {sub %}, and D{sub 50} {sub %}. In contrast, in patients whose rectal volume decreased, significance was only seen for D{sub 25} {sub %} and D{sub 50} {sub %} (D{sub x} {sub %} dose covering x % of the volume). In the latter patients, nonsignificant reductions in D{sub 2} {sub cc}, D{sub 5} {sub cc} and V{sub 5} {sub Gy} (volume receiving at least 5 Gy) were observed. The current rectal enemas protocol was ineffective in significantly modifying rectal DVH parameters for HDR-VCB. (orig.)

    Radiation proctopathy is a common unfortunate complication following radiation therapy of pelvic malignancies. Symptoms of chronic radiation proctopathy include haematochezia, urgency, constipation, tenesmus, diarrhoea and rectal pain. Currently, a wide variety of pharmacological options, endoscopic cautery techniques and surgical procedures have been proposed for the treatment of chronic radiation proctopathy. Although these have been proposed primarily as treatment for rectal bleeding, the control of other symptoms has been noted with some of these agents. Pharmacological options include 5-aminosalicylic acid preparations, coticosteroid enemas, sucralfate (oral, enemas), formalin, short chain fatty acid enemas, oestrogen/progesterone, hyperbaric oxygen, antioxidants, sodium pentosan polysulphate and misoprostol rectal suppositories. Of these, sucralfate and formalin therapy appear to be effective for bleeding control. Misoprostol rectal suppositories and oral sucralfate may be useful in the prevention of acute and chronic symptoms of radiation proctopathy. Endoscopic cautery techniques have included the use of Nd:YAG laser and argon laser for coagulation of bleeding neovascular telangiectasias. Argon plasma coagulation offers a safe non-contact method of delivering haemostasis which has proven to be particularly useful in targeting difficult to reach lesions tangentially. Surgery is generally reserved for severe refractory cases involving ongoing haemorrhage, obstruction, stricture formation, fistulas and perforation. Given that formal randomized placebo-controlled studies are lacking for most treatments, the management of these patients is often challenging and unclear. Hence, there is a need for more research and education on radiation proctopathy. PMID:11552895

    2016-07-01

    Solutions of 100 mL with 1.20 mM of salicylic acid (SA), 4-aminosalicylic acid (4-ASA) or 5-aminosalicylic acid (5-ASA) have been comparatively degraded by anodic oxidation with electrogenerated H2O2 (AO-H2O2), electro-Fenton (EF) and photoelectro-Fenton (PEF). Trials were carried out with a stirred tank reactor with a BDD anode and an air-diffusion cathode for continuous H2O2 production. A marked influence of the functional groups of the drugs was observed in their decay kinetics, increasing in the order SA H2O2 and 5-ASA H2O2 H2O2 at 100 mA cm(-2). The mineralization rate in EF and PEF grew in the order: 4-ASA 98% mineralization for all the drugs at 100 mA cm(-2). Oxalic and oxamic acids were detected as final short-linear aliphatic carboxylic acids by ion-exclusion HPLC, allowing the fast photolysis of their Fe(III) complexes by UVA light to justify the high power of PEF.

    Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant trait characterized by presentation of colorectal cancer (CRC) at an early age and by an increased risk of other primary malignancies, including those of the endometrium. ovaries, stomach, small bowel, upper biliary tract, skin, and brain, as well as by transitional cell carcinoma (TCC) that especially involves the renal pelvis and ureter. Because specific genetic mutations causing HNPCC have been recently discovered, genetic screening options have been developed for some families. Subsequently, radiology has an increasing role in surveillance for and management of these HNPCC-associated tumours. Although colonoscopy is the mainstay of a screening regimen for colon cancer, the barium enema has been a standard radiologic investigation. Further, computed tomography (CT) colonography (now practised in various centres) will, with further refinement, prove to be of increasing value. Ultrasonography is a standard investigation for endometrial and ovarian cancer, with CT and magnetic resonance (MR) imaging often playing a central role. As for TCC, intravenous urography (IVU) had been a standard investigation tool. However, with continued evolution of multidetector row CT with postprocessing manipulation (CT urography [CTU]), the role of IVU is diminishing in most centres. Newfoundland has a high prevalence of HNPCC exhibiting a broad range of manifestations. In this article, radiologic images of various tumours from individuals with HNPCC demonstrate a radiologic spectrum of this fascinating hereditary disease. Screening implications and specific screening methods are reviewed. (author)

  1. Preparation of Ethylcellulose Coated Gelatin Microspheres as a Multiparticulate Colonic Delivery System for 5-Aminosalicilic Acid

    Full Text Available In the long-term management of ulcerative colitis patients, repeat dosing maybe required. Since 5-ASAis largely absorbed from the upper intestine, selective delivery of drugs into the colon may be regarded as a better method of drug delivery with fewer side effects and a higher efficacy. The aim of this study was to prepare and evaluate a double coated multiparticulate system for 5-ASA delivery using gelatin and ethylcellulose as the primary and secondarypolymer respectively. Gelatin microspheres containing 5-aminosalicylic acid was produced using the solvent evaporation method. Prepared gelatin microspheres were spherical, freeflowing, non-aggregated and showed no degradation in the acidic medium. Entrapment efficacy of microspheres was about 50%. Results showed that drug release was fast and complete and is affected by the amount of core material entrapped. Gelatin microspheres werethen coated by ethylcellulose using a coacervation phase separation technique. The idea for this approach was to prepare a delayed drug delivery system, in which, ethylcellulose protects particles for the first 6 h transit through the gastrointestinal tract. However, it was shown that this system could provide a suitable drug release pattern for colonic delivery of active agents, as 30% of the drug was released from the ethylcellulose-coated microcapsules within 6 h,while this amount was 90% of the loaded drug for gelatin microspheres under the same condition.

  2. Colon-specific prodrugs of 4-aminosalicylic acid for inflammatory bowel disease.

    Dhaneshwar, Suneela S

    2014-04-01

    Despite the advent of biological products, such as anti-tumor necrosis factor-α monoclonal antibodies (infliximab and adalimumab), for treatment of moderate to severe cases of inflammatory bowel disease (IBD), most patients depend upon aminosalicylates as the conventional treatment option. In recent years, the increased knowledge of complex pathophysiological processes underlying IBD has resulted in development of a number of newer pharmaceutical agents like low-molecular-weight heparin, omega-3 fatty acids, probiotics and innovative formulations such as high-dose, once-daily multi-matrix mesalamine, which are designed to minimize the inflammatory process through inhibition of different targets. Optimization of delivery of existing drugs to the colon using the prodrug approach is another attractive alternative that has been utilized and commercialized for 5-aminosalicylic acid (ASA) in the form of sulfasalazine, balsalazide, olsalazine and ipsalazine, but rarely for its positional isomer 4-ASA - a well-established antitubercular drug that is twice as potent as 5-ASA against IBD, and more specifically, ulcerative colitis. The present review focuses on the complete profile of 4-ASA and its advantages over 5-ASA and colon-targeting prodrugs reported so far for the management of IBD. The review also emphasizes the need for reappraisal of this promising but unexplored entity as a potential treatment option for IBD. PMID:24707139

  3. Crohn's disease recurrence in patients with ileocolic anastomosis: Value of computed tomography enterography with water enema

    Objectives: the main objective of the present work was to determine the diagnostic value of CT-enterography with water enema (CTe-WE) in the assessment of the ileocolic anastomosis in patients with Crohn's disease (CD). The prevalence of synchronous inflammatory lesions (SILs) involving gastrointestinal segments distinct from the anastomosis was also determined. Further, the association between the type of ileocolic anastomosis and the behavior (i.e. inflammatory, stricturing, penetrating) of CD recurrence was evaluated. Methods: 51 patients were retrospectively included (26 [51%] male and 25 [49%] female; mean age: 52.88 years ± 13.35). Ileocolic anastomoses were: 18 (35.3%) stapled side-to-side, 17 (33.3%) end-to-side, and 16 (31.4%) end-to-end. CTe-WEs were reviewed in consensus by two gastrointestinal radiologists. Endoscopy and medical records were used as reference standards. Results: CTe-WE yielded 95.35% sensitivity (CI 95%: 84.19–99.43%), 75.00% specificity (CI 95%: 34.91–96.81%), and 92.15% diagnostic accuracy (CI 95%: 81.31–98.02%). Anastomotic recurrence was found in 41/51 (80.4%) patients, including 30/41 (73.2%) cases of isolated anastomotic recurrence, and 11/41 (26.8%) cases of anastomotic recurrence with a SIL. A significant lower prevalence of stricturing recurrence was observed in patients with stapled side-to-side anastomoses (p = 0.033). Conclusions: CTe-WE provides a good distension of both sides of ileocolic anastomoses allowing the detection of SILs

    2016-01-01

    Background/Aims A colon transit time test using radio-opaque markers (CTTRM) is considered the gold standard for evaluating colon transit function. A 24-hour delayed film of barium enema (BE) has been used as a supplementary method in structural evaluations. The aim of this study was to evaluate the utility of a 24-hour delayed BE film for assessing colon transit function in young children with constipation. Methods In total, 93 children with constipation who performed both single-contrast BE and CTTRM were enrolled in this study. Of these, the data from 70 children were analyzed (males 33, females 37; mean age [range], 5.63 ± 2.94 [2–14] years). The basic principle of the study is “velocity = distance/time”. Time values were identified in both studies, and the colon length and distance of barium movement were measured on the 24-hour delayed BE film. Thus, colon transit velocity values could be calculated using both methods. The correlation between colon transit velocity using a 24-hour delayed BE film versus CTTRM was analyzed statistically. Results Median value (interquartile range) of colon transit velocity using CTTRM was 1.57 (1.07–2.89) cm/hr, and that using BE of that was 1.58 (0.94–2.07) cm/hr. The Spearman correlation coefficient was 0.438 (P children younger than 4 years (r = 0.537, P = 0.032). Conclusions Although the correlation between BE and CTTRM was not very strong, the 24-hour delayed BE film could provide broad information about colon transit function in young children, especially those under 4 years who usually cannot undergo CTTRM.

    To compare the CT colonography (CTC) and double-contrast barium enema (DCBE) for colonic evaluation in patients with renal insufficiency. Two sequential groups of consecutive patients with renal insufficiency who had a similar risk for colorectal cancer, were examined by DCBE (n = 182; mean {+-} SD in age, 51 {+-} 6.4 years) and CTC (n = 176; 50 {+-} 6.7 years), respectively. CTC was performed after colon cleansing with 250-mL magnesium citrate (n = 87) or 4-L polyethylene glycol (n = 89) and fecal tagging. DCBE was performed after preparation with 250-mL magnesium citrate. Patients with colonic polyps/masses of {>=} 6 mm were subsequently recommended to undergo a colonoscopy. Diagnostic yield and positive predictive value (PPV) for colonic polyps/masses, examination quality, and examination-related serum electrolyte change were retrospectively compared between the two groups. Both the CTC and DCBE were positive for colonic polyps/masses in 28 (16%) of 176 and 11 (6%) of 182 patients, respectively (p = 0.004). Among patients with positive findings, 17 CTC and six DCBE patients subsequently underwent a colonoscopy and yielded a PPV of 88% (15 of 17 patients) and 50% (3 of 6 patients), respectively (p = 0.089). Thirteen patients with adenomatous lesions were detected in the CTC group (adenocarcinoma [n = 1], advanced adenoma [n = 6], and non-advanced adenoma [n = 6]), as compared with two patients (each with adenocarcinoma and advanced adenoma) in the DCBE group (p = 0.003). Six (3%) of 176 CTC and 16 (9%) of 182 DCBE examinations deemed to be inadequate (p 0.046). Electrolyte changes were similar in the two groups. In patients with renal insufficiency, CTC has a higher diagnostic yield and a marginally higher PPV for detecting colorectal neoplasia, despite a similar diagnostic yield for adenocarcinoma, and a lower rate of inadequate examinations as compared with DCBE.

    2007-10-01

    Full Text Available Abstract Background and Aims The standard whole-colon tests used to investigate patients with symptoms of colorectal cancer are barium enema and colonoscopy. Colonoscopy is the reference test but is technically difficult, resource intensive, and associated with adverse events, especially in the elderly. Barium enema is safer but has reduced sensitivity for cancer. CT colonography ("virtual colonoscopy" is a newer alternative that may combine high sensitivity for cancer with safety and patient acceptability. The SIGGAR trial aims to determine the diagnostic efficacy, acceptability, and economic costs associated with this new technology. Methods The SIGGAR trial is a multi-centre randomised comparison of CT colonography versus standard investigation (barium enema or colonoscopy, the latter determined by individual clinician preference. Diagnostic efficacy for colorectal cancer and colonic polyps measuring 1 cm or larger will be determined, as will the physical and psychological morbidity associated with each diagnostic test, the latter via questionnaires developed from qualitative interviews. The economic costs of making or excluding a diagnosis will be determined for each diagnostic test and information from the trial and other data from the literature will be used to populate models framed to summarise the health effects and costs of alternative approaches to detection of significant colonic neoplasia in patients of different ages, prior risks and preferences. This analysis will focus particularly on the frequency, clinical relevance, costs, and psychological and physical morbidity associated with detection of extracolonic lesions by CT colonography. Results Recruitment commenced in March 2004 and at the time of writing (July 2007 5025 patients have been randomised. A lower than expected prevalence of end-points in the barium enema sub-trial has caused an increase in sample size. In addition to the study protocol, we describe our approach to

    Asthma is a multi-factorial and complicated lung disorder of the immune system which has expanded to a wider ambit unveiling its etiology to be omnipresent at both ends of the spectrum involving basic pharmacology and in-depth immunology. As asthma occurs through triggered activation of various immune cells due to different stimuli, it poses a great challenge to uncover specific targets for therapeutic interventions. Recent pharmacotherapeutic approaches for asthma have been focused on molecular targeting of transcription factors and their signaling pathways; mainly nucleus factor kappa B (NFκB) and its associated pathways which orchestrate the synthesis of pro-inflammatory cytokines (IL-1β, TNF-α, GM-CSF), chemokines (RANTES, MIP-1a, eotaxin), adhesion molecules (ICAM-1, VCAM-1) and inflammatory enzymes (cyclooxygenase-2 and iNOS). 5-aminosalicylic acid (5-ASA) and sodium salicylate are known to suppress NFκB activation by inhibiting inhibitor of kappa B kinase (IKκB). In order to target the transcription factor, a suitable carrier system for delivering the drug to the intracellular space is essential. 5-ASA and sodium salicylate loaded liposomes incorporated into PEG-4-acrylate and CCRGGC microgels (a polymer formed by crosslinking of trypsin sensitive peptide and PEG-4-acrylate) could probably suit the needs for developing a disease responsive drug delivery system which will serve as a prophylactic therapy for asthmatic patients.

Methods Enema liquid was dripped into the intestines through intestinal stoma, and temperature and speed of enema liquid were controlled and regulated according to the conditions of intestines. Therapeutic effect was observed. Results Among the 11 patients, 4 paitents were cured and 7 patients were improved, the total effective rate was 100% . Conclusion Application of new retention enema can extend the contact time between drug and the intestinal mucosa, which promote the absorption of drugs and ensure the effect of enema. As a result, it can improve the comfortable degree of patients as well.

  12. The Malone Antegrade Continence Enema (MACE principle in children: is it important if the conduit is implanted in the left or the right colon?

    Full Text Available OBJECTIVE: The aim of the study was to determine which was the optimal side for the conduit to be placed (right or left colon for antegrade continence enema implantation. MATERIALS AND METHODS: Between July 1999 and March 2006, 31 patients underwent the construction of a catheterizable conduit using the Malone principle (MACE In 22 cases the conduit was re-implanted in the right colon and in 9 cases in the left colon. There were 20 male patients and 11 female patients, with a mean age of 10.23 years. The follow-up period varied from 3 from 83 months (average 25 months. Right and left implantation of the conduit in the colon were compared with regards to the presence of complications, volume of the solution utilized, frequency of colonic lavage, time needed for performing the enema, and degree of satisfaction. RESULTS: One patient with the conduit in the right colon, using the appendix, lost the mechanism after two month follow-up. Thirty patients remain clean and are all capable of performing self-catheterization. No statistically significant differences were found between the groups regarding the variables studied: complications (p = 1.000, solution volume (p = 0.996, time required (p = 0.790 and patient's rating (p = 0.670. The lavage frequency required for patients with the conduit in the right colon may be lower. CONCLUSION: The MACE principle was considered effective for treating fecal retention and leaks, independent of the implantation site. The success of this surgery appears to be directly related to the patient's motivation and not to the technique utilized.

  14. The change of radiation doses to the patient when switching from conventional technique to digital technique without films in barium enema and IVU examinations. Final report SSI research project P933

    Sjöholm, B

    2003-01-01

    X-ray examinations of the colon (barium enema) and the kidneys (IVU) are combined with rather high radiation doses to the patients when using analogue technique with film-screen systems. It is therefore of great interest to see if the change from analogue to digital technique involves a reduction of doses. Barium enema and IVU examinations were monitored with DAP-meters before and after the X-ray department changed to digital techniques. For IVU also the change from storage phosphor plates to a Direct Digital detector is included. The study comprises between 53 and 87 patients for each modality of the two examinations. A considerable dose reduction was observed. In barium enema the overview images with large field sizes were omitted when using digital technique. On the other hand the number of spot images was increased from 6 to 22. The fluoroscopy time was increased from 4 minutes to 6 minutes. The DAP value was reduced from 54,3 Gy cm sup 2 to 21,9 Gy cm sup 2. For IVU a dose reduction from 44,5 Gy cm sup 2...

  16. The value of colonoscopy and double-contrast barium-enema examinations in the evaluation of patients with subacute and chronic lower intestinal bleeding

    One hundred thirty six consecutive patients were examined with histories of guaiac positive stool examinations, bright red blood per rectum, or hematochezia to determine the value of the double-contrast barium-enema (DC-BE) examination and colonoscopy/proctoscopy in establishing bleeding sites. If examination findings were analyzed in conjunction with findings of visual examination of the anal area, the difference in the respective sensitivities of the two examinations was not statistically significant. If findings at the visual inspection were excluded, the DC-BE examination missed 45 of 155 proved bleeding sites (sensitivity, 71%) and 13 of 35 nonbleeding lesions (sensitivity for all lesions 70%), while colonoscopy missed 13 of 155 bleeding sites (sensitivity, 92%) and seven of 35 nonbleeding lesions (sensitivity for all lesions, 90%). The sensitivity of both methods was similar if all rectal and anal lesions were excluded. We conclude that colonoscopy is superior to the DC-BE examination in the detection of bleeding sites but similar in results to the DC-BE examination if lesions in the anal canal and rectum are excluded. The routine use of the DC-BE examination in patients with superficial lesions in the anal canal should be discouraged unless the patient has persistent bleeding or is 50 years old or older

  17. Patient acceptability of CT colonography compared with double contrast barium enema: results from a multicentre randomised controlled trial of symptomatic patients

    To determine patient acceptability of barium enema (BE) or CT colonography (CTC). After ethical approval, 921 consenting patients with symptoms suggestive of colorectal cancer who had been randomly assigned and completed either BE (N = 606) or CTC (N = 315) received a questionnaire to assess experience of the clinical episode including bowel preparation, procedure and complications. Satisfaction, worry and physical discomfort were assessed using an adapted version of a validated acceptability scale. Non-parametric methods assessed differences between the randomised tests and the effect of patient characteristics. Patients undergoing BE were significantly less satisfied (median 61, interquartile range [IQR] 54-67 vs. median 64, IQR 56-69; p = 0.003) and experienced more physical discomfort (median 40, IQR 29-52 vs. median 35.5, IQR 25-47; p < 0.001) than those undergoing CTC. Post-test, BE patients were significantly more likely to experience 'abdominal pain/cramps' (68% vs. 57%; p = 0.007), 'soreness' (57% vs. 37%; p < 0.001), 'nausea/vomiting' (16% vs. 8%; p = 0.009), 'soiling' (31% vs. 23%; p = 0.034) and 'wind' (92% vs. 84%; p = 0.001) and in the case of 'wind' to also rate it as severe (27% vs. 15%; p < 0.001). CTC is associated with significant improvements in patient experience. These data support the case for CTC to replace BE. (orig.)

  19. Effects of liquid paraffin in the diet or infused via colonic enema on fecal elimination of 14C-hexachlorobenzene from body burdens in rats

    Twenty-one male rats were dosed once intraperitoneally with 32.2 mg 14C-hexachlorobenzene in corn oil (14C-HCB activity 11.67 μCi/rat). After 4 d, six rats were randomly selected, bled and hemi-castrated with sampling of epididymal adipose tissue to establish 14C-HCB body burdens. Thereafter, all rats were allocated randomly into three groups, each with five intact and two hemi-castrated rats. One group (controls) received only a basal diet; another received the basal diet amended with 5% light mineral oil (MO); and the third received the basal diet and 1 ml of MO once daily via enema in the upper colon. Treatments were continued throughout 27 d. Excretion of 14C-HCB and(or) metabolites into feces and urine was measured daily for each rat for 31 d after 14C-HCB dosage. Fecal excretion of 14C-HCB and(or) metabolites was increased 2.5-fold by dietary MO and 1.7-fold by MO in the colon. When adjusted to equal dosage, MO by colon was 93% as effective as MO by diet. Urinary 14C-HCB excretion was not affected by MO, except indirectly through lowered body burden. Addition of hexadecane (25 μl per 100 mg adipose tissue) into the incubation mixture enhanced (P 14C-HCB into the liquid fraction for rats not previously fed hexadecane, but had no effect on incubation mixtures from rats fed hexadecane. Results confirm that liquid paraffins enhance elimination of 14C-HCB from body burdens into feces and suggest that distribution into blood cells and plasma may partially explain the effect

    本文报道经钡灌肠检查的89例肠梗阻病例.该检查有助于区别机械性与麻痹性肠梗阻及完全性与不完全性肠梗阻,有时还可发现造成肠梗阻的原发病变,对配合临床确定手术指征,选择合适治疗方案起重要作用.提出了钡灌肠X线特点、检查方法、适应证和禁忌证等.%Eighty-nine children with bowel obstruction were diagnosed with the help of barium enema and their diagnoses were confirmed by operation. The major findings are as follows: the high contrast barium-filled colon can be readily recognized among intestinal loops of different contrasty in the abdomen on the film. It is easy to make a differential diagnosi between a complete mechanical obstruction and a paralytic ileus. With the former, the contrast between a smaller gas-free colon and the gas-distended bigger small intestine with fluid-levels will be seen on the film;while with the latter, a gas-disteuded colon with barium-levels should be present on the film:Among the small intestines, the prestence of "coffee bean sign", "concentric loop" shadow, long air-fluid-level in a hypotonic loop, and the presence of peritoneal fluid should call attention to the possible strangulation of the intestine. Some of the primary causes of intestinal obstruction can also be shown on the film by using barium enema, such as the specific "cupping" shadow in intussusception, widening of interloop opacity in necrotic enteritis, microcolon in intestinal atresia of newborn, and spastic colon segment in Hirschsprung's disease. Methods, indications and contraindications of the use of barium enema are discussed in detail in the text.

  8. Minimal preparation computed tomography instead of barium enema/colonoscopy for suspected colon cancer in frail elderly patients: an outcome analysis study

    .43], negative predictive value 0.97 [0.96], positive likelihood ratio result 1.6 [5.63], negative likelihood ratio result 0.27 [0.29], kappa 0.31 [0.43]. Tumour prevalence was 12%. A graph of conditional probabilities was generated and analysed. A variety of unsuspected pathology was also found in this series of patients. CONCLUSIONS: MPCT should be double-reported, at least initially. 'Possible' lesions should be ignored. Analysis of the graph of conditional probability applied to a group of frail, elderly patients with a high mortality from all causes (33% in our study) suggests: (1) if MPCT suggests definite or probable carcinoma, regardless of the pre-test probability, the post-test probability is high enough to warrant further action, (2) frail, elderly patients with a low pre-test probability for CRC and a negative MPCT should not have further investigation, (3) frail, elderly patients with a higher pre-test probability of CRC (such as those presenting with rectal bleeding) and a negative MPCT should have either double contrast barium enema (DCBE) or colonoscopy as further investigations or be followed clinically for 3-6 months. MPCT was acceptable to patients and clinicians and may reveal significant extra-colonic pathology

    Background/Aim: Ulcerative colitis (UC) is a type of chronic inflammatory bowel disease with unknown etiology. Several therapeutic strategies such as consumption of medicinal plants have been used for its treatment. The aim of this study was to evaluate healing effects of Calendula officinalis hydroalcoholic extract in experimentally induced UC in rat. Materials and Methods: Ninety-six rats, weighing 200 ± 20 g, were randomly divided into eight equal groups. UC induced by 3% acetic acid and oral doses of C. officinalis extract, 1500 and 3000 mg/kg, and enema (gel 10% and 20%) were given. Two groups as positive controls were given asacol (enema) and oral mesalamine. Negative control groups were given normal saline and base gel. On days 3 and 7, intestinal histopathology and weight changes, plus oxidative stress indices including malondialdehyde (MDA) level and myeloperoxidase (MPO) activity were assayed. Results: A significant increase in the body weight of rats was seen in the group given C. officinalis extract 3000 mg/kg orally, oral mesalamine, and 20% intracolonic gel form of marigold extract compared with negative control and base gel groups during the experimental period. Acute inflammation and granular atrophy after UC induction were resolved completely completely by both 20% intracolonic gel and 3000 mg/kg orally. An increase in MPO activity and a decrease in MDA level in response to oral and intracolonic gel form of C. officinalis were observed 3 and and 7 days after treatment (P < 0.05). Conclusion: Our results indicate that oral and enema forms of hydroalcoholic extract of C. officinalis can be offered as are potential therapeutic agents for UC induced in rats. PMID:26831607

    Trinitrobenzene sulfonic acid (TNBS)-induced colitis is one of the most common methods for studying inflammatory bowel disease in animal models. Several factors may, however, affect its reproducibility, rate of animal mortality, and macroscopic and histopathological outcomes. Our aim was to validate the main contributing factors to this method and compare the effects of different reference drugs upon remission of resultant colon injuries. TNBS was dissolved in 0.25 ml of ethanol (50% v/v) and instilled (25, 50, 100 and 150 mg/kg) intracolonically to the male Wistar rats. After determination of optimum dose of TNBS in male rats and assessment of this dose in female rats, they were treated with reference drugs including dexamethasone [1 mg/kg, intraperitoneally (i.p.) and 2 mg/kg, orally (p.o.)], Asacol (mesalazine, 100 mg/kg, p.o.; 150 mg/kg, enema) and hydrocortisone acetate (20 mg/kg, i.p.; 20 mg/kg, enema) which started 2 h after colitis induction and continued daily for 6 consecutive days. Thereafter, macroscopic and microscopic parameters and clinical features were assessed and compared in different groups. We found that the optimum dose of TNBS for the reproducibility of colonic damage with the least mortality rate was 50 mg/kg. Amongst studied reference drugs, hydrocortisone acetate (i.p.), dexamethasone (i.p. and p.o.) and Asacol (p.o.) significantly diminished the severity of macroscopic and microscopic injuries and could be considered effective for experimental colitis studies in rats . Our findings suggest that optimization of TNBS dose is essential for induction of colitis under the laboratory conditions; and gender exerts no impact upon macroscopic and histological characteristics of TNBS-induced colitis in rats. Furthermore, the enema forms of hydrocortisone and Asacol are not appropriate reference drugs. PMID:23181094

  12. National audit of the sensitivity of double-contrast barium enema for colorectal carcinoma, using control charts - For the Royal College of Radiologists Clinical Radiology Audit Sub-Committee

    AIM: To audit the sensitivity of double-contrast barium enema (DCBE) for colorectal carcinoma, as currently practised in UK departments of radiology. METHODS: As part of its programme of national audits, the Royal College of Radiologists Clinical Radiology Audit Sub-Committee undertook a retrospective audit of the sensitivity of DCBE for colorectal carcinoma during 2002. The following targets were set: demonstration of a lesion >=95%; correct identification as a carcinoma >=90%.RESULTS: Across the UK, 131 departments took part in the audit, involving 5454 examinations. The mean demonstration rate was 92.9% and the diagnosis rate was 85.9%, slightly below the targets set. The equivocal rate (lesion demonstrated, but not defined as malignant) was 6.9%, the perception failure rate was 2.8% and the technical failure rate was 4.4%. Control-chart methodology was used to analyze the data and to identify any departments whose performance was consistent with special-cause variation.CONCLUSION: When compared with the diagnosis rate (84.6%) and demonstration rate (92.7%) reported in the Wessex Audit 1995, [Thomas RD, Fairhurst JJ, Frost RA. Wessex regional audit: barium enema in colo-rectal carcinoma. Clin Radiol 1995;50:647-50.] a similar level of performance was observed in the NHS today, implying that the basic process for undertaking and reporting DCBE has remained relatively unchanged over the last few years. Improvement in the future will require fundamental changes to the process of reporting DCBE, in order to minimize the perception failure rate and accurately to describe lesions, so reducing the equivocal rate. Control-chart methodology has a useful role in identifying strategies to deliver continual improvement

    Full Text Available Background: Free radicals are the known mechanisms responsible for inducing colitis with two origins: Inflammatory cells and tissues. Only the inflammatory cells can be controlled by corticosteroids. Our aim was to assess the importance of neutrophils as one of the inflammatory cells in inducing colitis and to evaluate the efficacy of corticosteroids in the treatment of inflammatory bowel disease (IBD. Materials and Methods: Thirty-six mice were divided into six groups of six mice each. Colitis was induced in three groups by exposing them to acetic acid through enema (group 1, ex vivo (group 3, and enema after immune suppression (group 5. Each group had one control group that was exposed to water injection instead of acetic acid. Tissue samples were evaluated and compared based on macroscopic damages and biochemical and pathological results. Results: Considering neutrophilic infiltration, there were significant differences between groups 1, 3, 5, and the control of group 1. Groups 3, 5, and their controls, and group 1 and the control of group 3 had significant differences in terms of goblet depletion. Based on tissue originated H 2 O 2 , we found significant differences between group 1 and its control and group 3, and also between groups 5 and the control of group 3. All the three groups were significantly different from their controls based on Ferric Reducing Ability of Plasma (FRAP and such differences were also seen between group 1 with two other groups. Conclusion: Neutrophils may not be the only cause of oxidation process in colitis, and also makes the effectiveness of corticosteroids in the treatment of this disease doubtful.

    AIM: To investigate the anti-oxidant and anti-neutrophil recruitment effects of rectal d-alpha (d-α) tocopherol administration on mild and moderately active ulcerative colitis (UC).METHODS: Fifteen patients with mild and moderately active ulcerative colitis were enrolled in an open-label study of d-α tocopherol enema (8000 U/d) for 12 wk. All patients were receiving concomitant therapy with 5-aminosalicylic acid derivatives (5-ASA) and/or immunomodulator medications. Endoscopic evaluation was performed at baseline and after 4th and 12th weeks. Disease activity was measured with the Mayo disease activity index (DAI) and remission was defined as DAI of≤2 with no blood in stool. Clinical response was defined as a DAI reduction of≥2.RESULTS: At the end of 12th week, the average DAI score significantly decreased compared to the beginning of the study (2.3±0.37 vs 8±0.48, P < 0.0001). One patient was withdrawn after 3 wk for being unavailable to follow-up. On the 4th week of therapy, 12 patients showed clinical response, 3 of whom (21.4%) achieving remission. After 12 wk, all 14 patients responded clinically to the therapy and remission was induced in 9 of them (64%). No patient reported adverse events or was hospitalized due to worsened disease activity.CONCLUSION: This preliminary report suggests that rectal d-α tocopherol may represent a novel therapy for mild and moderately active UC. The observed results might be due to the anti-inflammatory and anti-oxidative properties of vitamin E.

  4. Daily Sodium Butyrate Enema for the Prevention of Radiation Proctitis in Prostate Cancer Patients Undergoing Radical Radiation Therapy: Results of a Multicenter Randomized Placebo-Controlled Dose-Finding Phase 2 Study

    Purpose: To evaluate the efficacy of sodium butyrate enemas (NABUREN) in prostate cancer radiation therapy (RT) in reducing the incidence, severity, and duration of acute RT-induced proctitis. Methods and Materials: 166 patients, randomly allocated to 1 of 4 groups (rectal sodium butyrate 1 g, 2 g, or 4 g daily or placebo), were treated with NABUREN during and 2 weeks after RT. The grade of proctitis was registered in a daily diary. The correlation between NABUREN and proctitis was investigated through χ2 statistics. The toxicity endpoints considered were as follows: total number of days with grade ≥1 proctitis (≥G1); total number of days with grade ≥2 proctitis (≥G2); ≥G1 and ≥G2 proctitis lasting at least 3 and 5 consecutive days starting from week 4 (≥G1+3d, ≥G2+3d); damaging effects of RT on rectal mucosa as measured by endoscopy. The relationship between endpoints and pretreatment morbidities, hormonal therapy, presence of diabetes or hypertension, abdominal surgery, or hemorrhoids was investigated by univariate analysis. Results: The patients were randomly allocated to the 4 arms. No difference in the distribution of comorbidities among the arms was observed (P>.09). The mean ≥G1 and ≥G2 proctitis were 7.8 and 4.9 for placebo and 8.9 and 4.7 for the NABUREN group, respectively. No favorable trend in reduction of incidence, severity, and duration of ≥G1 and ≥G2 proctitis was observed with NABUREN use. In univariate analysis, ≥G1+3d toxicity was found to be related to hemorrhoids (P=.008), and a slight correlation was found between ≥G2 proctitis and hormonal therapy (P=.06). The RT effects on rectal mucosa as based on endoscopic assessment were mainly related to diabetes (P<.01). Endoscopy data at 6 week showed no significant difference between the placebo and butyrate arms. The other investigated endpoints were not correlated with any of the clinical risk factors analyzed. Conclusion: There was no evidence of efficacy of

    Full Text Available Obestatin, a 23-amino acid peptide derived from the proghrelin, has been shown to exhibit some protective and therapeutic effects in the gut. The aim of present study was to determine the effect of obestatin administration on the course of acetic acid-induced colitis in rats. Materials and Methods. Studies have been performed on male Wistar rats. Colitis was induced by a rectal enema with 3.5% acetic acid solution. Obestatin was administered intraperitoneally twice a day at a dose of 8 nmol/kg, starting 24 h after the induction of colitis. Seven or 14 days after the induction of colitis, the healing rate of the colon was evaluated. Results. Treatment with obestatin after induction of colitis accelerated the healing of colonic wall damage and this effect was associated with a decrease in the colitis-evoked increase in mucosal activity of myeloperoxidase and content of interleukin-1β. Moreover, obestatin administration significantly reversed the colitis-evoked decrease in mucosal blood flow and DNA synthesis. Conclusion. Administration of exogenous obestatin exhibits therapeutic effects in the course of acetic acid-induced colitis and this effect is related, at least in part, to the obestatin-evoked anti-inflammatory effect, an improvement of local blood flow, and an increase in cell proliferation in colonic mucosa.

    Ulcerative colitis (UC) is characterized by a long-standing chronic course with remissions and exacerbations. Previously, patients do not respond to 5-aminosalicylic acid compounds and corticosteroids are considered for colectomies, however, in recent years, alternative treatments emerged for steroid-refractory or steroid-dependent UC. In this review article, we focus on immunomodulators (such as azathioprine [AZA] and 6-mercaptopurine [6-MP]) and immunosuppressants (such as cyclosporine A [C...

By comparing the conformational energy profiles of ibotenic and thioibotenic acid with...... the conformations preferred by the ligands upon docking to mGlu1 and models of the other mGlu subtypes, we propose that unlike other subtypes, group III mGlu receptor binding sites require a ligand conformation at an energy level which is prohibitively expensive for ibotenic acid, but not for...

  4. [Gastric Acid].

    Ruíz Chávez, R

    1996-01-01

    Gastric acid, a product of parietal cells secretion, full fills multiple biological roles which are absolutely necessary to keep corporal homeostasis. The production of the acid depends upon an effector cellular process represented in the first step by histamine, acetilcholine and gastrin, first messengers of the process. These interact with specific receptors than in sequence activate second messengers -cAMP and the calcium-calmodulin system- which afterwards activate a kinase. An specific protein is then phosphorilated by this enzyme, being the crucial factor that starts the production of acid. Finally, a proton bomb, extrudes the acid towards the gastric lumen. The secretion process mentioned above, is progressive lyactivated in three steps, two of which are stimulators -cephalic and gastric phases- and the other one inhibitor or intestinal phase. These stages are started by mental and neurological phenomena -thought, sight, smell or memory-; by food, drugs or other ingested substances; and by products of digestion. Changes in regulation of acid secretion, in the structure of gastro-duodenal mucosal barrier by a wide spectrum of factors and agents including food, drugs and H. pylori, are the basis of acid-peptic disease, entity in which gastric acid plays a fundamental role. From the therapeutic point of view, so at the theoretical as at the practical levels, t is possible to interfere with the secretion of acid by neutralization of some of the steps of the effector cellular process. An adequate knowledge of the basics related to gastric acid, allows to create strategies for the clinical handling of associated pathology, specifically in relation to peptic acid disease in all of the known clinical forms.

  10. The influence of pretreatment with ghrelin on the development of acetic-acid-induced colitis in rats.

    Maduzia, D; Matuszyk, A; Ceranowicz, D; Warzecha, Z; Ceranowicz, P; Fyderek, K; Galazka, K; Dembinski, A

    2015-12-01

    Ghrelin has been primarily shown to exhibit protective and therapeutic effect in the gut. Pretreatment with ghrelin inhibits the development of acute pancreatitis and accelerates pancreatic recovery in the course of this disease. In the stomach, ghrelin reduces gastric mucosal damage induced by ethanol, stress or alendronate, as well as accelerates the healing of acetic acid-induced gastric and duodenal ulcer. The aim of present studies was to investigate the effect of pretreatment with ghrelin on the development of acetic acid-induced colitis. Studies have been performed on male Wistar rats. Animals were treated intraperitoneally with saline (control) or ghrelin (4, 8 or 16 nmol/kg/dose). Saline or ghrelin was given twice: 8 and 1 h before induction of colitis. Colitis was induced by a rectal enema with 1 ml of 4% solution of acetic acid and the severity of colitis was assessed 1 or 24 hours after induction of inflammation. Rectal administration of acetic acid induced colitis in all animals. Damage of colonic wall was seen at the macroscopic and microscopic level. This effect was accompanied by a reduction in colonic blood flow and mucosal DNA synthesis. Moreover, induction of colitis significantly increased mucosal concentration of pro-inflammatory interleukin-1β (IL-1β), activity of myeloperoxidase and concentration of malondialdehyde (MDA). Mucosal activity of superoxide dismutase (SOD) was reduced. Pretreatment with ghrelin reduced the area and grade of mucosal damage. This effect was accompanied by an improvement of blood flow, DNA synthesis and SOD activity in colonic mucosa. Moreover, ghrelin administration reduced mucosal concentration of IL-1β and MDA, as well as decreased mucosal activity of myeloperoxidase. Administration of ghrelin protects the large bowel against the development of the acetic acid-induced colitis and this effect seems to be related to the ghrelin-evoked anti-inflammatory and anti-oxidative effects.

The salt mixtures are prepared by neutralizing acid product mixtures from the oxidation of polyols using nitric acid and oxygen as the oxidizing agents. Nitric acid is removed from the hydroxycarboxylic acids by evaporation and diffusion dialysis.

  17. Efficacy and efficiency of small bowel double contrast enema

    Roedl, W.; Possel, H.M.; Prull, A.; Wunderlich, L.

    1986-02-01

    The double contrast examination is the most effective morphological screening method for the evaluation of the whole small intestine. Its sensitivity is 85%, its specifity 96.7%. In specific clinical problems the number of pathological roentgen rises: from 34,4% when all indications are taken into consideration to 58% in indications specific to the small intestine such as Morbus Crohn or the malabsorption syndrome. Search for tumors and the double contrast of the small intestine in unclear gastro-intestinal bleeding are unproductive. The weak point of this screening method is the lower part of the small intestine. Therefore, the selective peroral or retrograde analysis of the terminal ileum supplement the contrast method. A precondition for good results is an adequate technical standard. Besides the clinical results some technical results are therefore discussed such as contrast medium quantities, examination and X-ray time, radiation exposure and influences on the image quality.

  1. COMPARATIVE EFFICACY OF DIFFERENT REFERENCE DRUGS ON TRINITROBENZENESULFONIC ACID-INDUCED ULCERATIVE COLITIS IN THE RAT MODEL

    P.S.Venkatesan

    2013-06-01

    Full Text Available Crohn’s disease and Ulcerative colitis were chronic inflammatory disorders of the bowel categorized as inflammatory bowel diseases. Trinitrobenzene sulfonic acid (TNBS-induced colitis was one of the most common methods for studying inflammatory bowel disease in animal models. Several factors may, however, affect its reproducibility, rate of animal mortality, and macroscopic and histopathological outcomes.The current study was undertaken with the objective to validate the main contributing factors to this method and compare the effects of different reference drugs upon better amelioration of trinitrobenzenesulfonic acid (TNBS induced colitis. With the above objectives, ulcerative colitis was induced by intrarectal administration of TNBS in male Wistar rats at a dose rate of 20 mg in 0.5 mL of ethanol per animal for all groups except the negative control group, which received 0.5 mL of normal saline. Different reference drugs like dexamethasone (1 mg/kg, intraperitoneally (i.p. and 2 mg/kg, orally (p.o., hydrocortisone acetate (20 mg/kg, i.p.; 20 mg/kg, enema and sulfasalazine 500mg/kg ,p.o.were administered daily once from Day 3 to 9 except the negative and positive controls which received normal saline at the rate of 10 mL/kg body weight. All the animals were sacrificed on Day 10; the colons were excised and the colon morphology and net weight of the colon segment were graded and measured, respectively. The intestinal damage had improved significantly in the experiment groups that received different reference drugs which is comparable with sulfasalazine treated group. The experimental observations, gross pathology of intestinal lesions and statistical analysis reveals no significant difference among the different reference drugs treated groups.

  2. Retarded acid emulsion

    Fast, C.R.; Rixe, F.H.; Duffield, E.L. Jr.

    1972-08-01

    Compositions for use in acidizing hydrocarbon-bearing formations are described. Retarded acid emulsions of prolonged stability make it possible for the acid in this form to be displaced substantial distances out into the formation before becoming spent. The action of acid emulsions for use in acidizing hydrocarbon-bearing formations is prolonged by employing as the principal emulsifying agent an amine salt of dodecylbenzene sulfonic acid. Acid emulsions employing the amine salt of dodecylbenzene sulfonic acid exhibit greater stability than those employing the free acid. (8 claims)

  6. Acid distribution in phosphoric acid fuel cells

    Okae, I.; Seya, A.; Umemoto, M. [Fuji Electric Co., Ltd., Chiba (Japan)

    1996-12-31

    Electrolyte acid distribution among each component of a cell is determined by capillary force when the cell is not in operation, but the distribution under the current load conditions had not been clear so far. Since the loss of electrolyte acid during operation is inevitable, it is necessary to store enough amount of acid in every cell. But it must be under the level of which the acid disturbs the diffusion of reactive gases. Accordingly to know the actual acid distribution during operation in a cell is very important. In this report, we carried out experiments to clarify the distribution using small single cells.

Just as water dissolves an Alka-Seltzer tablet, acid rain erodes the limestone surfaces of Mexican archaeological sites at a rate of about one-half millimeter per century (Bravo et al. 2003). A half-millimeter may not seem like much, but at this pace, a few…

  10. Acid Deposition Phenomena

    Acid deposition, commonly known as acid rain, occurs when emissions from the combustion of fossil fuels and other industrial processes undergo complex chemical reactions in the atmosphere and fall to the earth as wet deposition (rain, snow, cloud, fog) or dry deposition (dry particles, gas). Rain and snow are already naturally acidic, but are only considered problematic when less than a ph of 5.0 The main chemical precursors leading to acidic conditions are atmospheric concentrations of sulfur dioxide (SO2) and nitrogen oxides (NOx). When these two compounds react with water, oxygen, and sunlight in the atmosphere, the result is sulfuric (H2SO4) and nitric acids (HNO3), the primary agents of acid deposition which mainly produced from the combustion of fossil fuel and from petroleum refinery. Airborne chemicals can travel long distances from their sources and can therefore affect ecosystems over broad regional scales and in locations far from the sources of emissions. According to the concern of petroleum ministry with the environment and occupational health, in this paper we will discussed the acid deposition phenomena through the following: Types of acidic deposition and its components in the atmosphere Natural and man-made sources of compounds causing the acidic deposition. Chemical reactions causing the acidic deposition phenomenon in the atmosphere. Factors affecting level of acidic deposition in the atmosphere. Impact of acid deposition. Procedures for acidic deposition control in petroleum industry

  4. Acidizing carbonate reservoirs with chlorocarboxylic acid salt solutions

    Richardson, E.A.; Scheuerman, R.F.; Templeton, C.C.

    1978-10-31

    A carbonate reservoir is acidized slowly by injecting an aqueous solution of a chlorocarboxylic acid salt so that the rate of the acidization is limited to the rate at which an acid is formed by the hydrolyzing of the chlorocarboxylate ions. The rate at which a chlorocarboxylic acid salt hydrolyzes to form an acid provides the desired rate of acid-release. A more complete acid-base reaction by chloroacetic acid, as compared to formic, acetic, and proprionic, is due to its being a much stronger acid. The pKa of chloroacetic acid is 2.86, whereas that of formic acid is 3.75, and that of acetic acid is 4.75. The pKa of a solution of a weak acid is the pH exhibited when the concentration of undissociated acid equals the concentration of the acid anion. 14 claims.

  8. Bile acid sequestrants

    Hansen, Morten; Sonne, David P; Knop, Filip K

    2014-01-01

    Bile acids are synthesized in the liver from cholesterol and have traditionally been recognized for their role in absorption of lipids and in cholesterol homeostasis. In recent years, however, bile acids have emerged as metabolic signaling molecules that are involved in the regulation of lipid and...... glucose metabolism, and possibly energy homeostasis, through activation of the bile acid receptors farnesoid X receptor (FXR) and TGR5. Bile acid sequestrants (BASs) constitute a class of drugs that bind bile acids in the intestine to form a nonabsorbable complex resulting in interruption of the...... enterohepatic circulation. This increases bile acid synthesis and consequently reduces serum low-density lipoprotein cholesterol. Also, BASs improve glycemic control in patients with type 2 diabetes. Despite a growing understanding of the impact of BASs on glucose metabolism, the mechanisms behind their glucose...
