With the market introduction of the NXE:3100, Extreme Ultra Violet Lithography (EUVL) enters a new stage. Now infrastructure in the wafer fabs must be prepared for new processes and new materials. Especially the infrastructure for masks poses a challenge. Because of the absence of a pellicle reticle front sides are exceptionally vulnerable to particles. It was also shown that particles on the backside of a reticle may cause tool down time. These effects set extreme requirements to the cleanliness level of the fab infrastructure for EUV masks. The cost of EUV masks justifies the use of equipment that is qualified on particle cleanliness. Until now equipment qualification on particle cleanliness have not been carried out with statistically based qualification procedures. Since we are dealing with extreme clean equipment the number of observed particles is expected to be very low. These particle levels can only be measured by repetitively cycling a mask substrate in the equipment. Recent work in the EUV AD-tool presents data on added particles during load/unload cycles, reported as number of Particles per Reticle Pass (PRP). In the interpretation of the data, variation by deposition statistics is not taken into account. In measurements with low numbers of added particles the standard deviation in PRP number can be large. An additional issue is that particles which are added in the routing outside the equipment may have a large impact on the testing result. The number mismatch between a single handling step outside the tool and the multiple cycling in the equipment makes accuracy of measurements rather complex. The low number of expected particles, the large variation in results and the combined effect of added particles inside and outside the equipment justifies putting good effort in making a test plan. Without a proper statistical background, tests may not be suitable for proving that equipment qualifies for the limiting cleanliness levels. Other risks are that a

Hotel room cleanliness is based on observation and not on microbial assessment even though recent reports suggest that infections may be acquired while staying in hotel rooms. Exploratory research in the first part of the authors' study was conducted to determine if contamination of hotel rooms occurs and whether visual assessments are accurate indicators of hotel room cleanliness. Data suggested the presence of microbial contamination that was not reflective of visual assessments. Unfortunately, no standards exist for interpreting microbiological data and other indicators of cleanliness in hotel rooms. The purpose of the second half of the authors' study was to examine cleanliness standards in other industries to see if they might suggest standards in hotels. Results of the authors' study indicate that standards from other related industries do not provide analogous criteria, but do provide suggestions for further research.

Construction site’s cleanliness and tidiness is one of top main concerns of construction site management. A good site management with adequate planning in regards to housekeeping will ensure safety to both the site’s working personnel and the neighbouring environment. This is especially of priority today due to the rapid growth of construction projects in Malaysia. Nevertheless, to date, statistics had shown that housekeeping related accidents happened repeatedly despite the awareness on site’s cleanliness and tidiness. The objective of this study was to explore constructor’s perspective on site cleanliness and tidiness. A set of questionnaire was distributed to thirty-four (34) Grade 7 CIDB contractors’ firms in Petaling Jaya. Petaling Jaya was chosen since this area are developed area covered with residential area and cleaning management an importance issues. The goals of the survey study were to identify the following items from the perception of the contractors: (i) the hierarchy of importance of several purposes in ensuring construction site’s cleanliness and tidiness, and (ii) the risk factors that influence a construction site’s level of cleanliness and tidiness. It was found that from the contractor’s perspective, ensuring a site cleanliness and tidiness is of importance mainly due to the need in protecting the environment, whilst, the least in cost saving. In addition, poor personnel’s working attitude was found to be the main risk factor that will influences a construction site’s level of cleanliness and tidiness. Conclusively, construction site’s cleanliness and tidiness is highly vital. Even so, for nationwide awareness on the topic matter will requires full cooperation from all related parties.

Indonesia's population has increased every year so the need for food increased, especially the availability of nutritious foods such as red meat. Red meat is one of the foods that contain sufficient elements of protein, but it was likely to contain heavy metals and bacterial contamination that has met the threshold standards. On the otherhand, beef bowels are very popular among Indonesian consumers, but many heavy metlas could accumulated into the bowels. The purpose of this research are to study the content of heavy metals and bacterial contamination on beef bowel from some places of slaughtering houses and some red meats from the market in Jakarta. The beef bowels are lung, tripe, intestine and liver while the red meats were veal and tender loin. Parameter of heavy metals measured are As, Cd and Hg, while for the initial bacterial contamination are total number of aerobic bacteria, total amount of coliform, Escherichia coli, Staphylococcus sp and Salmonella contamination. The heavy metals were analyzed using Neutron Activation Analysis, and for the total number of bacteria is using Total Plate Count. Result of research shows the As content in lung and tripe as well as the mercuric content in bowel has exceeded in the normal level such as 1.0 and 0.03 ppm, respectively. On the other hand, no heavy metals were detected in all red meats. The total microbes in beef bowel have exceeded allowable limit (1.0 x 10 6 cfu/g). No Salmonella was detected in all beef bowels and red meats observed. Nuclear technique are very helpful analysis of the heavy metas content in bowel dan red meats beef. The cleanliness slaughtering house of animals are remarkably ascertaining the quality of the beef bowel and red meats who will be sent. (author)

Cleanliness criteria to improve steam generator performance

International Nuclear Information System (INIS)

Schwarz, T.; Bouecke, R.; Odar, S.

2005-01-01

High steam generator performance is a prerequisite for high plant availability and possible life time extension. The major opponent to that is corrosion and fouling of the heating tubes. Such steam generator degradation problems arise from the continuous ingress of non-volatile contaminants, i.e. corrosion products and salt impurities may accumulate in the steam generators. These impurities have their origin in the secondary side systems. The corrosion products generally accumulate in the steam generators and form deposits not only in the flow restricted areas, such as on top of tube sheet and tube support structure, but also build scales on the steam generator heating tubes. In addition, the tube scales in general affect the steam generator thermal performance, which ultimately causes a reduction of power output. The most effective ways of counteracting all these degradation problems, and thus of improving the steam generator performance is to keep them in clean conditions or, if judged necessary, to plan cleaning measures such as mechanical tube sheet lancing or chemical cleaning. This paper presents a methodology how to assess the cleanliness condition of a steam generator by bringing together all available operational and inspection data such as thermal performance and water chemistry data. By means of this all-inclusive approach the cleanliness condition is quantified in terms of a fouling index. The fouling index allows to monitor the condition of a specific steam generator, compare it to other plants and, finally, to serve as criterion for cleaning measures such as chemical cleaning. The application of the cleanliness criteria and the achieved field results with respect to improvements of steam generator performance will be presented. (author)

Urban surfaces receive waste deposits from natural and human sources, which create a negative visual impact and are identified as potentially significant contributors to water and air pollution. Local councils are usually responsible for the sweep of roads and footpaths to keep the environment clean and free of litter. Quality controls are useful in order to check whether the services are being executed according to the quantity, quality and performance standards that are provided. In this sense, several factors might affect the efficiency of the management of cleaning and waste collection services; however, only a few contributions are available in the literature on the various aspects associated with the level of street cleanliness. In this paper, the suitability of a Cleanliness Index has been checked, for the case of Granada (South of Spain), in order to contribute to the proper management of public expenditure, improving the quality and cost of an essential service for any municipality. Results have concluded that the city exhibits a good level of cleanliness, although the standard of cleaning varied from one area of the city to another. The Cleaning Index fits well to the general situation of the different districts of Granada and thus, it could be considered a useful tool for measuring the level of cleanliness of the streets of the city and for evaluating the organization of the cleaning service, such that an outsourced company would not be responsible for controlling all the cleaning services.

Full Text Available This single center, randomized, and controlled study aimed to compare the effectiveness and safety of polyethylene glycol electrolyte lavage (PEG-EL solution and colonic hydrotherapy (CHT for bowel preparation before colonoscopy. A total of 196 eligible outpatients scheduled for diagnostic colonoscopy were randomly assigned to the PEG-EL (n=102 or CHT (n=94 groups. Primary outcome measures included colonic cleanliness and adverse effects. Secondary outcome measures were patient satisfaction and preference, colonoscopic findings, ileocecal arrival rate, examiner satisfaction, and cecal intubation time. The results show that PEG-EL group was associated with significantly better colonic cleanliness than CHT group, fewer adverse effects, and increased examiner satisfaction. However, the CHT group had higher patient satisfaction and higher diverticulosis detection rates. Moreover, the results showed the same ileocecal arrival rate and patient preference between the two groups (P>0.05. These findings indicate that PEG-EL is the preferred option in patients who followed the preparation instructions completely.

Successful colonoscopies require good bowel preparations-poor bowel preparations can increase medical costs, rates of missed lesions, and procedure duration. The combination of polyethylene glycol (PEG) 3350 without electrolytes (MiraLAX; Schering-Plough Healthcare Products, Inc, Kenilworth, NJ) and 64 oz of Gatorade (PepsiCo, Inc, Purchase, NY) has gained popularity as a bowel preparation regimen. However, the efficacy and tolerability of this approach has not been compared with standard bowel preparations in clinical trials. We compared split-dose (PEG) 3350 with electrolytes (GoLytely; Braintree Laboratories, Inc, Braintree, MA) with split-dose MiraLAX alone and in combination with pretreatment medications (bisacodyl or lubiprostone) to determine the efficacy and patient tolerability of MiraLAX as an agent for bowel preparation. We performed a prospective, randomized, blinded, controlled trial at a tertiary care center. Patients (n=403) were randomly assigned to groups given GoLytely, MiraLAX, MiraLAX with bisacodyl (10 mg), or MiraLAX with lubiprostone (24 μg). MiraLAX was combined with 64 oz of Gatorade. All patients were surveyed regarding preparation satisfaction and tolerability. The Ottawa bowel preparation scale was used to grade colon cleanliness. GoLytely was more effective at bowel cleansing (average Ottawa score, 5.1) than MiraLAX alone (average Ottawa score, 6.9) or in combination with lubiprostone (average Ottawa score, 6.8), or bisacodyl (average Ottawa score, 6.3) (P<.001). MiraLAX was associated with a trend toward longer procedure duration (P=.096). Groups given MiraLAX rated the overall experience as more satisfactory than those given GoLytely (P<.001). There were no differences between polyp detection rates (P=.346) or adverse events (P=.823). Split-dose MiraLAX in 64 oz of Gatorade is not as effective as 4 L split-dose GoLytely in bowel cleansing for screening colonoscopies. Copyright © 2011 AGA Institute. Published by Elsevier Inc. All

The cleanliness requirements for an organic-detection instrument, like the Mars Organic Molecule Analyzer Mass Spectrometer (MOMA-MS), on a Planetary Protection Class IVb mission can be extremely stringent. These include surface molecular and particulate, outgassing, and bioburden. The prime contractor for the European Space Agencys ExoMars 2018 project, Thales Alenia Space Italy, provided requirements based on a standard, conservative approach of defining limits which yielded levels that are unverifiable by standard cleanliness verification methods. Additionally, the conservative method for determining contamination surface area uses underestimation while conservative bioburden surface area relies on overestimation, which results in inconsistencies for the normalized reporting. This presentation will provide a survey of the challenge to define requirements that can be reasonably verified and still remain appropriate to the core science of the ExoMars mission.

Sena-Graph syrup has recently been formulated by an Iranian pharmaceutical company for being used in bowel evacuation before radiography, colonoscopy and surgery. This study compares the efficacy, adverse effects and patient compliance of two bowel preparation regimens with castor oil and Sena-Graph syrup in of outpatients for Intravenous Urography (IVU). One hundred and fourteen consecutive outpatients were randomized to receive either the standard bowel preparation with 60 mL of castor oil or the test method with 60 mL of Sena-Graph syrup before IVU examination. Demographic data of patients and their prior bowel preparation experience were collected before the examination. Two radiologists, blinded to the method of bowel preparation, reviewed the radiographs and graded the bowel preparation. The compliance and acceptability of both regimens were assessed by using structured questionnaires filled by the patients. The Numbers, ages, weights and gender distribution of patients and their prior bowel preparation experience in the two groups did not differ significantly. The cleanliness scores for the castor oil and Sena-Graph group were 3.97 ± 0.971 and 4.87 ± 0.917, respectively. The results indicated that Sena-Graph syrup causes a better bowel cleansing compared castor oil. Adverse effects in Sena-Graph groups were significantly lower than the castor oil group. Acceptability of the regimen in patients who used Sena-Graph was higher than the other group. The Sena-Graph regimen is significantly more effective and better tolerated than of Castor oil regimen in bowel cleansing. The incidence and severity of the adverse effects from Castor oil was higher than Sena-Graph.

The UK and China provide unique historical perspectives on the evolution of the incidence of inflammatory bowel disease, which might provide insight into its pathogenesis. Historical records from the UK document the emergence of ulcerative colitis during the mid-1800s, which was later followed by the recognition of Crohn's disease in 1932. During the second half of the 20th century, the incidence of inflammatory bowel disease rose dramatically in high-income countries. Globalisation at the turn of the 21st century led to rapid economic development of newly industrialised countries such as China. In China, the modernisation of society was accompanied by the recognition of a sharp rise in the incidence of inflammatory bowel disease. The prevalence of inflammatory bowel disease is expected to continue to rise in high-income countries and is also likely to accelerate in the developing world. An understanding of the shared and different environmental determinants underpinning the pathogenesis of inflammatory bowel disease in western and eastern countries is essential to implement interventions that will blunt the rising global burden of inflammatory bowel disease.

The minimum bacterial detection limits and operator reproducibility of the Biotrace Clean-Tracetrade mark Rapid Cleanliness Test and traditional hygiene swabbing were determined. Areas (100 cm2) of food grade stainless steel were separately inoculated with known levels of Staphylococcus aureus (NCTC 6571) and Escherichia coli (ATCC 25922). Surfaces were sampled either immediately after inoculation while still wet, or after 60 min when completely dry. For both organisms the minimum detection limit of the ATP Clean-Tracetrade mark Rapid Cleanliness Test was 10(4) cfu/100 cm2 (p 10(7) cfu/100 cm2. Hygiene swabbing percentage recovery rates for both organisms were less than 0.1% for dried surfaces but ranged from 0.33% to 8.8% for wet surfaces. When assessed by six technically qualified operators, the Biotrace Clean-Tracetrade mark Rapid Cleanliness Test gave superior reproducibility for both clean and inoculated surfaces, giving mean coefficients of variation of 24% and 32%, respectively. Hygiene swabbing of inoculated surfaces gave a mean CV of 130%. The results are discussed in the context of hygiene monitoring within the food industry. Copyright 1999 John Wiley & Sons, Ltd.

The aim of this study was to evaluate the amount of dust in supply air ducts in recently installed ventilation systems. The samples for the determination of dust accumulation were collected from supply air ducts in 18 new buildings that have been constructed according to two different cleanliness control levels classified as category P1 (low oil residues and protected against contaminations) and category P2, as defined in the Classification of Indoor Climate, Construction and Building Materials. In the ducts installed according to the requirements of cleanliness category P1 the mean amount of accumulated dust was 0.9 g/m2 (0.4-2.9 g/m2), and in the ducts installed according to the cleanliness category P2 it was 2.3 g/m2 (1.2-4.9 g/m2). A significant difference was found in the mean amounts of dust between ducts of categories P1 and P2 (P < 0.008). The cleanliness control procedure in category P1 proved to be a useful and effective tool for preventing dust accumulation in new air ducts during the construction process. Additionally, the ducts without residual oil had lower amounts of accumulated dust indicating that the demand for oil free components in the cleanliness classification is reasonable.

The mechanical cleaning and TV inspection technology for secondary-side in steam generators of Daya Bay Nuclear Power Plant has been used for preventing the heat transfer tubes from damage caused by residues in steam generator and foreign objects. A lancing has been used for steam generators. The high-pressure jet sent from the central lane to the inside of the bundle has two objectives: (a) the mechanical energy in the jet breaks up the deposit, and (b) the particles are then carried to the periphery of the generator, where they are collected by a water circulation system. The TV inspection consists of the inspection before lancing and after lancing. The former includes the inspection of outer tube lane and central tube lane, and the extraction of foreign objects; the latter includes the inspection of inter tube area, outer tube lane and central tube lane, and the extraction of foreign objects. Video cassette are visualized by a specialist who is qualified to realize a map representative of the cleanliness state of the tubesheet, and to judge if it is or not acceptable. The TV inspection obtained a cleanliness conclusion according to acceptance criteria. So, it is important to work out cleanliness acceptance criteria suit for every operation stages. The site practices shown that after lancing, although hard deposit existed and height of hard deposit in some local place exceeded 5 mm, but the sludge remaining on tubesheet was less. If we can conduct periodic lancing to steam generator, the increase rate of hard deposit will be small. (7 refs., 12 figs.)

Background IBS affects 5–11% of the population of most countries. Prevalence peaks in the third and fourth decades, with a female predominance. Aim To provide a guide for the assessment and management of adult patients with irritable bowel syndrome. Methods Members of the Clinical Services Committee of The British Society of Gastroenterology were allocated particular areas to produce review documents. Literature searching included systematic searches using electronic databases such as Pubmed, EMBASE, MEDLINE, Web of Science, and Cochrane databases and extensive personal reference databases. Results Patients can usefully be classified by predominant bowel habit. Few investigations are needed except when diarrhoea is a prominent feature. Alarm features may warrant further investigation. Adverse psychological features and somatisation are often present. Ascertaining the patients' concerns and explaining symptoms in simple terms improves outcome. IBS is a heterogeneous condition with a range of treatments, each of which benefits a small proportion of patients. Treatment of associated anxiety and depression often improves bowel and other symptoms. Randomised placebo controlled trials show benefit as follows: cognitive behavioural therapy and psychodynamic interpersonal therapy improve coping; hypnotherapy benefits global symptoms in otherwise refractory patients; antispasmodics and tricyclic antidepressants improve pain; ispaghula improves pain and bowel habit; 5‐HT3 antagonists improve global symptoms, diarrhoea, and pain but may rarely cause unexplained colitis; 5‐HT4 agonists improve global symptoms, constipation, and bloating; selective serotonin reuptake inhibitors improve global symptoms. Conclusions Better ways of identifying which patients will respond to specific treatments are urgently needed. PMID:17488783

The objective of this study was to develop the Automated Steel Cleanliness Analysis Tool (ASCATTM) to permit steelmakers to evaluate the quality of the steel through the analysis of individual inclusions. By characterizing individual inclusions, determinations can be made as to the cleanliness of the steel. Understanding the complicating effects of inclusions in the steelmaking process and on the resulting properties of steel allows the steel producer to increase throughput, better control the process, reduce remelts, and improve the quality of the product. The ASCAT (Figure 1) is a steel-smart inclusion analysis tool developed around a customized next-generation computer controlled scanning electron microscopy (NG-CCSEM) hardware platform that permits acquisition of inclusion size and composition data at a rate never before possible in SEM-based instruments. With built-in customized ''intelligent'' software, the inclusion data is automatically sorted into clusters representing different inclusion types to define the characteristics of a particular heat (Figure 2). The ASCAT represents an innovative new tool for the collection of statistically meaningful data on inclusions, and provides a means of understanding the complicated effects of inclusions in the steel making process and on the resulting properties of steel. Research conducted by RJLG with AISI (American Iron and Steel Institute) and SMA (Steel Manufactures of America) members indicates that the ASCAT has application in high-grade bar, sheet, plate, tin products, pipes, SBQ, tire cord, welding rod, and specialty steels and alloys where control of inclusions, whether natural or engineered, are crucial to their specification for a given end-use. Example applications include castability of calcium treated steel; interstitial free (IF) degasser grade slag conditioning practice; tundish clogging and erosion minimization; degasser circulation and optimization; quality assessment

Inflammatory Bowel Disease: An Expanding Global Health Problem

Directory of Open Access Journals (Sweden)

Amosy E. M'koma

2013-01-01

Full Text Available This review provides a summary of the global epidemiology of inflammatory bowel diseases (IBD. It is now clear that IBD is increasing worldwide and has become a global emergence disease. IBD, which includes Crohn's disease (CD and ulcerative colitis (UC, has been considered a problem in industrial-urbanized societies and attributed largely to a Westernized lifestyle and other associated environmental factors. Its incidence and prevalence in developing countries is steadily rising and has been attributed to the rapid modernization and Westernization of the population. There is a need to reconcile the most appropriate treatment for these patient populations from the perspectives of both disease presentation and cost. In the West, biological agents are the fastest-growing segment of the prescription drug market. These agents cost thousands of dollars per patient per year. The healthcare systems, and certainly the patients, in developing countries will struggle to afford such expensive treatments. The need for biological therapy will inevitably increase dramatically, and the pharmaceutical industry, healthcare providers, patient advocate groups, governments and non-governmental organizations should come to a consensus on how to handle this problem. The evidence that IBD is now affecting a much younger population presents an additional concern. Meta-analyses conducted in patients acquiring IBD at a young age also reveals a trend for their increased risk of developing colorectal cancer (CRC, since the cumulative incidence rates of CRC in IBD-patients diagnosed in childhood are higher than those observed in adults. In addition, IBD-associated CRC has a worse prognosis than sporadic CRC, even when the stage at diagnosis is taken into account. This is consistent with additional evidence that IBD negatively impacts CRC survival. A continuing increase in IBD incidence worldwide associated with childhood-onset of IBD coupled with the diseases’ longevity

A global perspective on irritable bowel syndrome: a consensus statement of the World Gastroenterology Organisation Summit Task Force on irritable bowel syndrome.

LENUS (Irish Health Repository)

Quigley, Eamonn M M

2012-08-15

Irritable bowel syndrome (IBS) is common in western Europe and North America, and many aspects of its epidemiology, risk factors, and natural history have been described in these regions. Recent data suggest, however, that IBS is also common in the rest of the world and there has been some evidence to suggest some differences in demographics and presenting features between IBS in the west and as it is experienced elsewhere. The World Gastroenterology Organization, therefore, established a Task Force comprising experts on the topic from all parts of the world to examine IBS from a global perspective. IBS does, indeed, seem to be common worldwide though with some significant variations in prevalence rates between regions and countries and there may well be some potentially interesting variations in presenting symptoms and sex distribution. The global map of IBS is far from complete; community-based prevalence data is not available from many areas. Furthermore, while some general trends are evident in terms of IBS impact and demographics, international comparisons are hampered by differences in diagnostic criteria, study location and methodology; several important unanswered questions have been identified that should form the basis for future collaborative research and have the potential to shed light on this challenging disorder.

To investigate the prevalence of malnutrition in patients with inflammatory bowel disease (IBD) by subjective global assessment (SGA) and the effects of oral nutritional support on the clinical parameters, consumption of energy, macronutrients and fiber intake in the Study and Control groups, prospectively. A total of 38 (28 Male; 10 Female) hospitalized patients with moderate or severe IBD (13 with Crohn's disease (CD); 25 with Ulcerative colitis (UC)) were included. At stage 1, the disease severity, clinical symptoms and, signs, food consumption and nutritional status by using subjective global assessment (SGA) were recorded. At stage 2, the patients were blindly randomized into a Study Group and Controls. In the Study Group, a standard enteral product was added into the regulated hospital diets, but for the Controls, deficits were regulated by only hospital diets for 3 weeks. the independent variables were the group, the disease and its activity, age, Body body mass index (BMI), weight loss history, the hospitalization period; the dependent variables were SGA, bowel movements, change in nutritional status, disease severity, clinical findings, and also consumption of macronutrients. Prevalance of malnutrition (SGA-B or SGA-C) for all the patients was 92.1% at the beginning and 71.1% at the end of study. Improvements in disease activity score for the patients with UC were statistically significant in both the Study Group and the Controls (p=0.006 for the Study Group and p=0.001 for the Controls, respectively). Macronutrients, total and water soluble fiber consumption levels improved, with statistically significant differences for all the groups. The prevalence of malnutrition is a major problem in patients with IBD. Not only the regulation of hospital food, but also enteral nutritional support, improved their levels of malnutrition, as well as their energy, macronutrients, and fiber consumption, and SGA is an easy method for nutritional monitoring.

Mediastinitis costs hospitals thousands of dollars a year and increases the incidence of patient morbidity and mortality. No studies have been done to evaluate adenosine triphosphate (ATP) counts on disposable and nondisposable electrocardiography (ECG) lead wires in pediatric patients. To compare the cleanliness of disposable and nondisposable ECG lead wires in postoperative pediatric cardiac surgery patients by measuring the quantity of ATP (in relative luminescence units [RLUs]). ATP levels correlate with microbial cell counts and are used by institutions to assess hospital equipment and cleanliness. A prospective, randomized trial was initiated with approval from the institutional review board. Verbal consent was obtained from the parents/guardians for each patient. Trained nurses performed ATP swabs on the right and left upper ECG cables on postoperative days 1, 2, and 3. This study enrolled 51 patients. The disposable ECG lead wire ATP count on postoperative day 1 (median, 157 RLUs) was significantly lower (P disposable ECG lead wires (median, 200 RLUs) was also lower (P = .06) than the count for the nondisposable ECG lead wires (median, 453 RLUs). Results of this study support the use of disposable ECG lead wires in postoperative pediatric cardiac surgery patients for at least the first 48 hours as a direct strategy to reduce the ATP counts on ECG lead wires. ©2014 American Association of Critical-Care Nurses.

A bacterial spore assay and a molecular DNA microarray method were compared for their ability to assess relative cleanliness in the context of bacterial abundance and diversity on spacecraft surfaces. Colony counts derived from the NASA standard spore assay were extremely low for spacecraft surfaces. However, the PhyloChip generation 3 (G3) DNA microarray resolved the genetic signatures of a highly diverse suite of microorganisms in the very same sample set. Samples completely devoid of cultivable spores were shown to harbor the DNA of more than 100 distinct microbial phylotypes. Furthermore, samples with higher numbers of cultivable spores did not necessarily give rise to a greater microbial diversity upon analysis with the DNA microarray. The findings of this study clearly demonstrated that there is not a statistically significant correlation between the cultivable spore counts obtained from a sample and the degree of bacterial diversity present. Based on these results, it can be stated that validated state-of-the-art molecular techniques, such as DNA microarrays, can be utilized in parallel with classical culture-based methods to further describe the cleanliness of spacecraft surfaces.

A multi-stage random sampling oral epidemiological survey was conducted in private and government, urban, rural town and rural village schools in 15 illakas of Sunsari District, Eastern Nepal. A total of 600, 12-13-year-old and 600 15-year-old school children were examined by trained examiners using the simplified oral hygiene index (OHI-S. The average age-group, debris and calculus index scores were combined to obtain the simplified oral hygiene index (OHI-S. The mean OHI-S scores were compared and evaluated using the parametric t-test for two independent samples. The mean OHI-S for urban 12-13-year-old school children was 0.98 compared to 1.34 for school children of rural towns and 1.44 for school children of rural villages and these differences in mean OHI-S were statistically significant ( P < 0.005. In the 15-year-old age group, urban school children had a mean OHI-S score of 1.00 compared to 1.37 for rural towns and 1.43 for rural villages. The variance in the mean OHI-S scores were statistically significant ( P < 0.005. The overall level of cleanliness in the school children surveyed was good. Children of urban schools had the lowest scores followed by school children from rural towns and then rural villages. When the mean OHI-S scores were compared with the DMFT scores, there was an inverse relationship between oral cleanliness and dental caries. Frequency of sugar consumption and the availability and affordability of fluoridated toothpaste may be important factors in the development of dental caries than oral cleanliness.

Engineering Work Plan for Development of Sludge Pickup Adapter for Fuel Cleanliness Inspections

International Nuclear Information System (INIS)

PITNER, A.L.

2000-01-01

The plan for developing an adapter to suction up sludge into a calibrated tube for fuel cleanliness inspection activities is described. A primary assessment of fuel cleanliness to be performed after processing through the Primary Cleaning Machine is whether the volume of any remaining canister sludge in or on a fuel assembly exceeds the allowable 14 cm 3 limit. It is anticipated that a general visual inspection of the sludge inventory after fuel assembly separation will usually suffice in making this assessment, but occasions may arise where there is some question as to whether or not the observed quantity of sludge exceeds this limit. Therefore a quantitative method of collecting and measuring the sludge volume is needed for these borderline situations. It is proposed to develop an adapter that fits on the end of the secondary cleaning station vacuum wand that will suction the material from the sludge collection tray into a chamber marked with the limiting volume to permit a direct go/no-go assessment of the sludge quantity

Full Text Available In this study, we aimed to determine gastrointestinal problems associated with neurogenic bowel dysfunction in spinal cord injury patients and to assess the efficacy of bowel program on gastrointestinal problems and the severity of neurogenic bowel dysfunction. Fifty-five spinal cord injury patients were included in this study. A bowel program according to the characteristics of neurogenic bowel dysfunction was performed for each patient. Before and after bowel program, gastrointestinal problems (constipation, difficult intestinal evacuation, incontinence, abdominal pain, abdominal distension, loss of appetite, hemorrhoids, rectal bleeding and gastrointestinal induced autonomic dysreflexia and bowel evacuation methods (digital stimulation, oral medication, suppositories, abdominal massage, Valsalva maneuver and manual evacuation were determined. Neurogenic bowel dysfunction score was used to assess the severity of neurogenic bowel dysfunction. At least one gastrointestinal problem was identified in 44 (80% of the 55 patients before bowel program. Constipation (56%, 31/55 and incontinence (42%, 23/55 were the most common gastrointestinal problems. Digital rectal stimulation was the most common method for bowel evacuation, both before (76%, 42/55 and after (73%, 40/55 bowel program. Oral medication, enema and manual evacuation application rates were significantly decreased and constipation, difficult intestinal evacuation, abdominal distention, and abdominal pain rates were significantly reduced after bowel program. In addition, mean neurogenic bowel dysfunction score was decreased after bowel program. An effective bowel program decreases the severity of neurogenic bowel dysfunction and reduces associated gastrointestinal problems in patients with spinal cord injury.

Irritable bowel syndrome (IBS) causes gastrointestinal symptoms such as abdominal pain, bloating, and bowel pattern abnormalities, which compromise patients’ daily functioning. Common therapies address one or two IBS symptoms, while others offer wider symptom control, presumably by targeting pathophysiologic mechanisms of IBS. The aim of this targeted literature review was to capture clinical trial reports of agents receiving the highest recommendation (Grade 1) for treatment of IBS from the 2009 American College of Gastroenterology IBS Task Force, with an emphasis on diarrhea-predominant IBS. Literature searches in PubMed captured articles detailing randomized placebo-controlled trials in IBS/diarrhea-predominant IBS for agents receiving Grade I (strong) 2009 American College of Gastroenterology IBS Task Force recommendations: tricyclic antidepressants, nonabsorbable antibiotics, and the 5-HT3 receptor antagonist alosetron. Studies specific for constipation-predominant IBS were excluded. Tricyclic antidepressants appear to improve global IBS symptoms but have variable effects on abdominal pain and uncertain tolerability; effects on stool consistency, frequency, and urgency were not adequately assessed. Nonabsorbable antibiotics show positive effects on global symptoms, abdominal pain, bloating, and stool consistency but may be most efficacious in patients with altered intestinal microbiota. Alosetron improves global symptoms and abdominal pain and normalizes bowel irregularities, including stool frequency, consistency, and fecal urgency. Both the nonabsorbable antibiotic rifaximin and the 5-HT3 receptor antagonist alosetron improve quality of life. Targeted therapies provide more complete relief of IBS symptoms than conventional agents. Familiarization with the quantity and quality of evidence of effectiveness can facilitate more individualized treatment plans for patients with this heterogeneous disorder. PMID:22754282

Short bowel syndrome

This thesis describes some aspects of short bowel syndrome. When approximately 1 m or less small bowel is retained after extensive resection, a condition called short bowel syndrome is present. Since the advent of parenteral nutrition, the prognosis of patients with a very short bowel has dramatically improved. Patients with 40 to 100 cm remaining jejunum and/or ileum can generally be maintained with oral nutrition due to increased absorption of the small bowel remnant as result of intestinal adaptation. This study reports clinical, biochemical and nutritional aspects of short bowel patients on oral or parenteral nutrition, emphasizing data on absorption of various nutrients and on bone metabolism. Furthermore, some technical apsects concerning long-term parenteral nutrition are discussed. (Auth.)

The study aimed to determine whether Coca-Cola (Coke) Zero is a safe and effective solvent for polyethylene glycol (PEG). Between December 2013 and April 2014, 209 healthy adults (115 men, 95 women) scheduled for elective colonoscopy were randomized to use either Coke Zero (n = 100) or drinking water (n = 109) with PEG as bowel preparation. Each patient received two sachets of PEG to dissolve in 2 l of solvent, to be completed 6 h before colonoscopy. Serum electrolytes were measured before and after preparation. Bowel cleanliness and colonoscopy findings were recorded. Palatability of solution, adverse effects, time taken to complete and willingness to repeat the preparation were documented via questionnaire. Mean palatability scores in the Coke Zero group were significantly better compared with the control group (2.31 ± 0.61 vs 2.51 ± 0.63, P = 0.019), with a higher proportion willing to use the same preparation again (55% vs 43%). The mean time taken to complete the PEG + Coke Zero solution was significantly faster (74 ± 29 min vs 86 ± 31 min, P = 0.0035). The quality of bowel cleansing was also significantly better in the Coke Zero group (P = 0.0297). There was no difference in the frequency of adverse events (P = 0.759) or the polyp detection rate (32% vs 31.2%). Consumption of either preparation did not significantly affect electrolyte levels or hydration status. Coke Zero is a useful alternative solvent for PEG. It is well tolerated, more palatable, leads to quicker consumption of the bowel preparation and results in better quality cleansing.

The methane decomposition in a planar RF discharge (13.56 MHz) leads both to a dust-particle generation in the plasma bulk and to a coating growth on the electrodes. Growing dust-particles fall onto the grounded electrode when they are too heavy. Thus, at the end of the experiment, the grounded electrode is covered by a coating and by fallen dust-particles. During the dust-particle growth, the negative DC self-bias voltage (VDC) increases because fewer electrons reach the RF electrode, leading to a more resistive plasma and to changes in the plasma chemical composition. In this paper, the cleanliness influence of the RF electrode on the dust-particle growth, on the plasma characteristics and composition is investigated. A cleanliness electrode is an electrode without coating and dust-particles on its surface at the beginning of the experiment.

The cleanliness of transferred graphene is of significant importance for its application as the window material in environmental cells used for electron microscopy and spectroscopy. We investigated the dependence of the cleanliness of graphene on transfer routes, including FeCl 3 etching, (NH 4 ) 2 S 2 O 8 etching, electrochemical delamination, and O 2 -bubbling, by means of transmission electron microscopy and X-ray photoelectron spectroscopy. It was found that electrochemical delamination provided the cleanest graphene with only a small amount of poly(methyl methacrylate) (PMMA) residue existing on the surface. (author)

Bowel-associated dermatosis-arthritis syndrome (BADAS) is a neutrophilic dermatosis, characterized by the occurrence of arthritis and skin lesions related to bowel disease with or without bowel bypass. We report an unusual case of BADAS in a 15-year-old white male with congenital aganglionosis of the colon and hypoganglionosis of the small intestine and multiple bowel surgeries in childhood complicated by short bowel syndrome. He presented with recurrent peripheral polyarthritis, tenosynovitis, and painful erythematous subcutaneous nodules located on the dorsolateral regions of the legs and on the dorsa of the feet. Histological examination disclosed a neutrophilic dermatosis confirming the diagnosis of BADAS.Although an uncommon disease, especially at pediatric age, it is important to evoke the diagnosis of BADAS in children and adolescents with bowel disease, because treatment options and prognosis are distinct from other rheumatologic conditions.

Hawrelak, Jason A; Myers, Stephen P

2010-10-01

The study objective was to assess the effects and tolerability of two novel natural medicine formulations in improving bowel habit and abdominal symptoms in patients with irritable bowel syndrome (IBS). The DA-IBS formula was designed to treat diarrhea-predominant and alternating bowel habit IBS, and the C-IBS formula was designed to treat constipation-predominant IBS. This was a two arm, open-label, uncontrolled pilot study. Subjects were recruited from the greater Lismore area (NSW, Australia) in 2001. The study included 31 patients who fulfilled the Rome II criteria for IBS. Twenty-one (21) patients were classified as suffering from diarrhea-predominant or alternating bowel habit IBS and 10 patients were classified with constipation-predominant IBS. The DA-IBS formula consisted of a mixture of dried, powdered bilberry fruit, slippery elm bark, agrimony aerial parts, and cinnamon quills. The C-IBS formula consisted of a mixture of dried powdered slippery elm bark, lactulose, oat bran, and licorice root. The aim of each formula was to normalize stool frequency and stool consistency. Ingestion of the DA-IBS formula was associated with a small, but significant increase in bowel movement frequency (p = 0.027). Subjects in the DA-IBS group also experienced reductions in straining (p = 0.004), abdominal pain (p = 0.006), bloating (p < 0.0001), flatulence (p = 0.0001), and global IBS symptoms (p = 0.002) during the treatment phase of the trial. Subjects in the C-IBS group experienced a 20% increase in bowel movement frequency (p = 0.016) and significant reductions in straining (p < 0.0001), abdominal pain (p = 0.032), bloating (p = 0.034), and global IBS symptom severity (p = 0.0005), as well as improvements in stool consistency (p < 0.0001). Both formulas were well-tolerated. The DA-IBS formula was not effective in improving bowel habit in individuals with diarrhea-predominant or alternating bowel habit IBS, although it did significantly improve a number of IBS

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.)

Large bowel obstruction may present as an emergency as high-grade colonic obstruction and can result in perforation. Perforated large bowel obstruction causes faecal peritonitis, which can result in high morbidity and mortality. Multidetector row computed tomography (MDCT) has the potential of providing an accurate diagnosis of large bowel obstruction. The rapid acquisition of images within one breath-hold reduces misregistration artefacts than can occur in critically ill or uncooperative patients. The following is a review of the various causes of large bowel obstruction with emphasis on important pathogenic factors, CT appearances and the use of multiplanar reformatted images in the diagnostic workup.

Evolution of the Lunar Receiving Laboratory to the Astromaterial Sample Curation Facility: Technical Tensions Between Containment and Cleanliness, Between Particulate and Organic Cleanliness

The Lunar Receiving Laboratory (LRL) was planned and constructed in the 1960s to support the Apollo program in the context of landing on the Moon and safely returning humans. The enduring science return from that effort is a result of careful curation of planetary materials. Technical decisions for the first facility included sample handling environment (vacuum vs inert gas), and instruments for making basic sample assessment, but the most difficult decision, and most visible, was stringent biosafety vs ultra-clean sample handling. Biosafety required handling of samples in negative pressure gloveboxes and rooms for containment and use of sterilizing protocols and animal/plant models for hazard assessment. Ultra-clean sample handling worked best in positive pressure nitrogen environment gloveboxes in positive pressure rooms, using cleanable tools of tightly controlled composition. The requirements for these two objectives were so different, that the solution was to design and build a new facility for specific purpose of preserving the scientific integrity of the samples. The resulting Lunar Curatorial Facility was designed and constructed, from 1972-1979, with advice and oversight by a very active committee comprised of lunar sample scientists. The high precision analyses required for planetary science are enabled by stringent contamination control of trace elements in the materials and protocols of construction (e.g., trace element screening for paint and flooring materials) and the equipment used in sample handling and storage. As other astromaterials, especially small particles and atoms, were added to the collections curated, the technical tension between particulate cleanliness and organic cleanliness was addressed in more detail. Techniques for minimizing particulate contamination in sample handling environments use high efficiency air filtering techniques typically requiring organic sealants which offgas.

Authors designed a customized Small Bowel Displacement System(SBDS) to displace the small bowel from the pelvic radiation fields and minimize treatment-related bowel morbidities. From August 1995 to May 1996, 55 consecutive patients who received pelvic radiation therapy with the SBDS were included in this study. The SBDS consists of a customized styrofoam compression device which can displace the small bowel from the radiation fields and an individualized immobilization abdominal board for easy daily setup in prone position. After opacifying the small bowel with Barium, the patients were laid prone and posterior-anterior (PA) and lateral (LAT) simulation films were taken with and without the SBDS. The areas of the small bowel included in the radiation fields with and without the SBDS were compared. Using the SBDS, the mean small bowel area was reduced by 59% on PA and 51% on LAT films (P=0.0001). In six patients (6/55, 11%), it was possible that no small bowel was included within the treatment fields. The mean upward displacement of the most caudal small bowel was 4.8 cm using the SBDS. Only 15% (8/55) of patients treated with the SBDS manifested diarrhea requiring medication. The SBDS is a novel method that can be used to displace the small bowel away from the treatment portal effectively and reduce the radiation therapy morbidities. Compliance with setup is excellent when the SBDS is used. (author)

The purpose of this study was to evaluate whether affected bowel in Crohn's disease patients can be identified by observing decreased peristalsis (frozen bowel sign) using cine balanced steady-state free precession (cine BSSFP) images. 5 radiologists independently reviewed cine BSSFP sequences from randomized MR Enterography (MRE) exams for 30 normal and 30 Crohn's disease patients, graded overall small bowel peristalsis from slowest to fastest, and graded peristalsis for the most abnormal small bowel segment. Sensitivity and specificity of the frozen bowel sign for diagnosing Crohn's disease were calculated. T tests of the peristalsis difference between abnormal segments and overall small bowel were conducted. For 5 readers, the sensitivity and specificity of cine BSSFP of the frozen bowel sign for diagnosing Crohn's disease ranged from 70% to 100% and 87% to 100%, respectively. There were significant differences in peristalsis between abnormal small bowel segments and the overall small bowel for Crohn's patients, but not in the overall small bowel between normal-MRE patients and Crohn's disease patients. Abnormal Crohn's small bowel segments have significantly decreased peristalsis compared to normal small bowel, which can be identified using cine BSSFP sequences as the frozen bowel sign.

Irritable bowel syndrome: Is it "irritable brain" or "irritable bowel"?

Directory of Open Access Journals (Sweden)

Susanta Kumar Padhy

2015-01-01

Full Text Available Irritable bowel syndrome (IBS has been recognized as one of the most common and best studied disorders among the group of functional gastrointestinal disorders. It is a functional bowel disorder in which abdominal pain or discomfort is associated with defecation or a change in bowel habit. In the Western world, IBS appears to affect up to 20% of the population at any given time but in Asian countries, the median value of IBS prevalence defined by various criteria ranges between 6.5% and 10.1%, and community prevalence of 4% is found in North India. Those attending gastroenterology clinics represent only the tip of the iceberg. The disorder substantially impairs the quality of life, and the overall health-care costs are high. IBS has therefore gained increased attention from clinicians, researchers, and pharmaceutical industries. It is often frustrating to both patients and physicians as the disease is usually chronic in nature and difficult to treat. However, the understanding of IBS has been changing from time to time and still most of its concepts are unknown. In this review we have discussed, debated, and synthesized the evidence base, focusing on underlying mechanisms in the brain and bowel. We conclude that it is both brain and bowel mechanisms that are responsible. The clinical implication of such mechanisms is discussed.

Full Text Available This article has as aim to announce the results of a clinical question referred about the intestinal cleanliness method most adapted for the pediatric population before a colorectal surgery, in order to diminish the electrolytic alterations for the utilization of the same ones and hereby to provide a better intestinal preparation with the minor risks. Is true the method of intestinal cleanliness it is a medical indication, the infirmary professionals must think about his work and wonder it brings over of his own practice and to work in a surest way (Young, 2003. There was realized a search, review and analysis of the scientific literature for that there were use different databases, as for example seeker academic GOOGLE, administrators of articles PUBMED, MEDLINE, EMBASE, SCIELO and Cochrane in Spanish and English language. Found 31 investigations that refer to the interest topic in indirect form. The conclusion were that the fosfosoda oral is effective and better tolerated in the intestinal cleanlinesses with the exception of the magnesium citrate who overcomes in flavor, for this could be an option for the use in pediatric populations. Nevertheless to use cautiously it's recommended to take renal function test and electrolytic pre, trans and post administration, added to the use of intravenous solutions mixed or electrolytic balanced intravenous as reinstatement to the losses. Nevertheless, there is no forceful evidence to determine which method of intestinal cleanliness is better and less risky for the children.

Bowel preparation represents an essential part of CT colonography, as the accuracy of the exam is strongly related to the adequacy of colonic cleansing, and a poor bowel preparation may compromise the diagnostic quality even despite optimization of all other acquisition parameters. Residual stool and fluid in the large bowel may affect the interpretation of the exam and may increase the number of false positives and false negatives. In this regard, the majority of patients having undergone CT colonography state that bowel preparation is the most unpleasant part. Unfortunately, to date no definite consensus has been reached about the ideal bowel preparation technique, and there is great variability in preparation strategies across diagnostic centers. The purpose of this review article is to describe the development and evolution of bowel preparation techniques in order to choose the best approach for optimizing the diagnostic quality of CT colonography in each patient

Adenocarcinoma of small bowel is generally a rather rare primary tumour of small bowel with a prevalence rate of 0.5 - 3.0 / 100.000 population, but the most frequent tumour of small intestine. It more often involves the duodenum and jejunum than the ileum. The aim of this paper is also to point out the value of small bowel follow through (SBFT) in the diagnosis of stenosing lesions. An 83 - year old male patient suffered from abdominal pain, malaise, vomiting, cachexia and diarrhoea for 3 months. The result of occult blood testing was negative. Haemoglobin level was normal. Proctoscopy, colonoscopy, upper gastrointestinal (GI) endoscopy, and ultrasonography (US) did not explain the patient's problems. Ileus of the small bowel was established with abdominal plain film. Small bowel follow through (SBFT) and computer tomography (CT) showed a stenosing tumour in the jejunum. Adenocarcinoma of the small bowel was established with histological examination after resection of the tumor. SBFT, with manual compression of all segments of the small bowel, can be a very accurate diagnostic investigation for evaluation of stenosing lesions in this part of the intestine. (author)

Inflammatory bowel disease has been associated with neurological symptoms including restless legs syndrome. Here, we investigated the impact of restless legs syndrome in patients with inflammatory bowel disease on sleep, fatigue, mood, cognition, and quality of life. Two groups of inflammatory bowel disease patients, with and without restless legs syndrome, were prospectively evaluated for sleep disorders, fatigue, daytime sleepiness, depression, anxiety, and health-related quality of life. Furthermore, global cognitive function, executive function, attention, and concentration were assessed in both groups. Disease activity and duration of inflammatory bowel disease as well as current medication were assessed by interview. Inflammatory bowel disease patients with and without restless legs syndrome were matched for age, education, severity, and duration of their inflammatory bowel disease. Patients with inflammatory bowel disease and clinically relevant restless leg syndrome suffered significantly more frequent from sleep disturbances including sleep latency and duration, more fatigue, and worse health-related quality of life as compared to inflammatory bowel disease patients without restless legs syndrome. Affect and cognitive function including cognitive flexibility, attention, and concentration showed no significant differences among groups, indicating to be not related to restless legs syndrome. Sleep disorders including longer sleep latency, shorter sleep duration, and fatigue are characteristic symptoms of restless legs syndrome in inflammatory bowel disease patients, resulting in worse health-related quality of life. Therefore, clinicians treating patients with inflammatory bowel disease should be alert for restless legs syndrome.

Stricturoplasty is a surgical option for management of severe stricturing Crohn's disease of the small bowel. It avoids the need for small bowel resection and the associated metabolic complications. This report contrasts the indications and technical aspects of two different stricturoplasty techniques. Case 1 describes an extensive Michelassi (side-to-side isoperistaltic) stricturoplasty performed for a 100 cm segment of diseased small bowel in a 45-year-old patient. Case 2 describes the performance of 12 Heineke-Mikulicz stricturoplasties in a 23-year-old patient with multiple short fibrotic strictures.

The purpose of this study was to compare two osmotic carbohydrate sugar alcohols (mannitol 2.5% and sorbitol 2.5%, 2.0%, and 1.5% watery solutions) in combination with 0.2% locust bean gum (LBG) for small bowel distension for MR imaging. Small bowel distension was quantified on coronal 2D TrueFISP images by measuring the diameters of 16 small bowel loops in each of 12 healthy subjects (age range 31-55 years). Additionally, the grade of small bowel distension was rated qualitatively. Patient acceptance concerning nausea, vomiting, flatulence, and diarrhea was noted for each solution, and all results were compared by a Wilcoxon test or t test, respectively. The ingestion of water combined with LBG and either 2.5% mannitol or 2.0% sorbitol showed the best distension of the small bowel. The lowest side effect rate was observed following ingestion of sorbitol in a concentration of 2.0 and 1.5%. Based on these data, we recommend a combination of LBG and 2% sorbitol use for optimal bowel distension and minimal side effects resulting in enhanced patient acceptance. (orig.)

Sarin Yogesh

2006-01-01

Full Text Available OBJECTIVES: To describe our experience with bowel vaginoplasty done in children. MATERIALS AND METHODS: This is a retrospective study of eight children aged 10 months to 8 years, who underwent bowel vaginoplasty over a period of 5 years (2000-2005. The indications of bowel vaginoplasty included anorectovestibular fistula (ARVF associated with Mayer-Rokitansky-Kuster-Hauser (MRKH syndrome (n=6 and cloaca (n=2. The bowel segment used for vaginoplasty included colon (n=3, ileum (n=2 and duplicated rectum (n=1. In two patients of ARVF associated with uterovaginal agenesis, the distal- most part of ARVF was transected at the level of peritoneal reflection and left as neovagina, whereas the proximal bowel was pulled through at the proposed neo-anal site. All the patients were advised daily home dilatation of the neo vaginal orifice with Hegar′s dilators, for a period of six weeks. RESULTS: Bowel vaginoplasty was done in eight patients. None had any significant per-operative complication. Two patients had abdominal wound dehiscence, requiring secondary suturing. Two patients had mucosal prolapse of the neovagina, which required trimming. One patient died two months after discharge, because of meningitis. Out of the eight patients, seven are in regular follow-up. Six patients have neovagina, cosmetically acceptable to the parents; all have been radiologically proven to have adequate length. One patient had unacceptable perineal appearance with nipple-like vaginal orifice and scarred perineal wound, that merits a revision. None of the patients had vaginal stenosis and excessive mucus discharge, during follow-up visits. Although post surgical results are acceptable to the parents cosmetically, the sexual and psychological outcome is yet to be assessed. Conclusions: Bowel vaginoplasty is a safe and acceptable procedure to treat the pediatric patients of uterovaginal agenesis and cloaca.

To investigate the accuracy and inter-observer variation of bowel sound assessment in patients with clinically suspected bowel obstruction. Bowel sounds were recorded in patients with suspected bowel obstruction using a Littmann(®) Electronic Stethoscope. The recordings were processed to yield 25-s sound sequences in random order on PCs. Observers, recruited from doctors within the department, classified the sound sequences as either normal or pathological. The reference tests for bowel obstruction were intraoperative and endoscopic findings and clinical follow up. Sensitivity and specificity were calculated for each observer and compared between junior and senior doctors. Interobserver variation was measured using the Kappa statistic. Bowel sound sequences from 98 patients were assessed by 53 (33 junior and 20 senior) doctors. Laparotomy was performed in 47 patients, 35 of whom had bowel obstruction. Two patients underwent colorectal stenting due to large bowel obstruction. The median sensitivity and specificity was 0.42 (range: 0.19-0.64) and 0.78 (range: 0.35-0.98), respectively. There was no significant difference in accuracy between junior and senior doctors. The median frequency with which doctors classified bowel sounds as abnormal did not differ significantly between patients with and without bowel obstruction (26% vs 23%, P = 0.08). The 53 doctors made up 1378 unique pairs and the median Kappa value was 0.29 (range: -0.15-0.66). Accuracy and inter-observer agreement was generally low. Clinical decisions in patients with possible bowel obstruction should not be based on auscultatory assessment of bowel sounds.

Shared toilets in urban slums are often unclean and poorly maintained, discouraging consistent use and thereby limiting impacts on health and quality of life. We developed behaviour change interventions to support shared toilet maintenance and improve user satisfaction. We report the intervention effectiveness on improving shared toilet cleanliness. We conducted a cluster-randomised controlled trial among users of 1226 shared toilets in 23 Dhaka slums. We assessed baseline toilet cleanliness in January 2015. The six-month intervention included provision of hardware (bin for solid waste, 4 l flushing bucket, 70 l water reservoir), and behaviour change communication (compound meetings, interpersonal household sessions, signs depicting rules for toilet use). We estimated the adjusted difference in difference (DID) to assess outcomes and accounted for clustering effects using generalised estimating equations. Compared to controls, intervention toilets were more likely to have water available inside toilet cubicles (DID: +4.7%, 95% CI: 0.2, 9.2), access to brush/broom for cleaning (DID: +8.4%, 95% CI: 2, 15) and waste bins (DID: +63%, 95% CI: 59, 66), while less likely to have visible faeces inside the pan (DID: -13%, 95% CI: -19, -5), the smell of faeces (DID: -7.6%, 95% CI: -14, -1.3) and household waste inside the cubicle (DID: -4%, 95% CI: -7, -1). In one of few efforts to promote shared toilet cleanliness, intervention compounds were significantly more likely to have cleaner toilets after six months. Future research might explore how residents can self-finance toilet maintenance, or employ mass media to reduce per-capita costs of behaviour change. © 2017 John Wiley & Sons Ltd.

Fetal bowel anomalies - US and MR assessment

Energy Technology Data Exchange (ETDEWEB)

Rubesova, Erika [Stanford University, Department of Radiology, Lucile Packard Children' s Hospital, Stanford, CA (United States)

2012-01-15

The technical quality of prenatal US and fetal MRI has significantly improved during the last decade and allows an accurate diagnosis of bowel pathology prenatally. Accurate diagnosis of bowel pathology in utero is important for parental counseling and postnatal management. It is essential to recognize the US presentation of bowel pathology in the fetus in order to refer the patient for further evaluation or follow-up. Fetal MRI has been shown to offer some advantages over US for specific bowel abnormalities. In this paper, we review the normal appearance of the fetal bowel on US and MRI as well as the typical presentations of bowel pathologies. We discuss more specifically the importance of recognizing on fetal MRI the abnormalities of size and T1-weighted signal of the meconium-filled distal bowel. (orig.)

The MIR Environmental Effects Payload (MEEP) was attached to the Docking Module of the MIR space station for 18 months during calendar years 1996 and 1997 (March 1996, STS 76 to October 1997, STS 86). A solar panel array with more than 10 years space exposure was removed from the MIR core module in November 1997, and returned to Earth in January, 1998, STS 89. MEEP and the returned solar array are part of the International Space Station (ISS) Risk Mitigation Program. This space flight hardware has been inspected and studied by teams of space environmental effects (SEE) investigators for micrometeoroid and space debris effects, space exposure effects on materials, and electrical performance. This paper reports changes in cleanliness of parts of MEEP and the solar array due to the space exposures. Special attention is given to the extensive water soluble residues deposited on some of the flight hardware surfaces. Directionality of deposition and chemistry of these residues are discussed.

Inflammatory Bowel Disease in Primary Immunodeficiencies.

Science.gov (United States)

Kelsen, Judith R; Sullivan, Kathleen E

2017-08-01

Inflammatory bowel disease is most often a polygenic disorder with contributions from the intestinal microbiome, defects in barrier function, and dysregulated host responses to microbial stimulation. There is, however, increasing recognition of single gene defects that underlie a subset of patients with inflammatory bowel disease, particularly those with early-onset disease, and this review focuses on the primary immunodeficiencies associated with early-onset inflammatory bowel disease. The advent of next-generation sequencing has led to an improved recognition of single gene defects underlying some cases of inflammatory bowel disease. Among single gene defects, immune response genes are the most frequent category identified. This is also true of common genetic variants associated with inflammatory bowel disease, supporting a pivotal role for host responses in the pathogenesis. This review focuses on practical aspects related to diagnosis and management of children with inflammatory bowel disease who have underlying primary immunodeficiencies.

Several factors influence bowel preparation quality. Recent studies have indicated that the time interval between bowel preparation and the start of colonoscopy is also important in determining bowel preparation quality. To evaluate the influence of the preparation-to-colonoscopy (PC) interval (the interval of time between the last polyethylene glycol dose ingestion and the start of the colonoscopy) on bowel preparation quality in the split-dose method for colonoscopy. Prospective observational study. University medical center. A total of 366 consecutive outpatients undergoing colonoscopy. Split-dose bowel preparation and colonoscopy. The quality of bowel preparation was assessed by using the Ottawa Bowel Preparation Scale according to the PC interval, and other factors that might influence bowel preparation quality were analyzed. Colonoscopies with a PC interval of 3 to 5 hours had the best bowel preparation quality score in the whole, right, mid, and rectosigmoid colon according to the Ottawa Bowel Preparation Scale. In multivariate analysis, the PC interval (odds ratio [OR] 1.85; 95% CI, 1.18-2.86), the amount of PEG ingested (OR 4.34; 95% CI, 1.08-16.66), and compliance with diet instructions (OR 2.22l 95% CI, 1.33-3.70) were significant contributors to satisfactory bowel preparation. Nonrandomized controlled, single-center trial. The optimal time interval between the last dose of the agent and the start of colonoscopy is one of the important factors to determine satisfactory bowel preparation quality in split-dose polyethylene glycol bowel preparation.

MRI for chronic inflammatory bowel disease

Hansmann, H.J.; Hess, T.; Hahmann, M.; Erb, G.; Richter, G.M.; Duex, M.; Elsing, C.

2001-01-01

Chronic inflammatory bowel disease is diagnosed and monitored by the combination of colonoscopy and small bowel enteroklysis. Magnetic resonance imaging has become the gold standard for the imaging of perirectal and pelvic fistulas. With the advent of ultrafast MRI small and large bowel imaging has become highly attractive and is being advocated more and more in the diagnostic work up of inflammatory bowel disease. Imaging protocols include fast T 1 -weighted gradient echo and T 2 -weighted TSE sequences and oral or rectal bowel distension. Furthermore, dedicated imaging protocols are based on breath-hold imaging under pharmacological bowel paralysis and gastrointestinal MR contrast agents (Hydro-MRI). High diagnostic accuracy can be achieved in Crohn's disease with special reference to the pattern of disease, depth of inflammation, mesenteric reaction, sinus tract depiction and formation of abscess. In ulcerative colitis, the mucosa-related inflammation causes significantly less bowel wall thickening compared to Crohn's disease. Therefore with MRI, the extent of inflammatory changes is always underestimated compared to colonoscopy. According to our experience in more than 200 patients as well as the results in other centers, Hydro-MRI possesses the potential to replace enteroklysis in the diagnosis of chronic inflammatory bowel disease and most of the follow-up colonoscopies in Crohn's disease. Further technical improvements in 3D imaging will allow interactive postprocessing of the MR data. (orig.) [de

Small bowel tumors are rarely detected unless there is intestinal obstruction or bleeding. In the seven years 1982-1988, at Kosin Medical Center, 25 primary malignant small bowel tumors were studied radiographically with barium and / or computed tomography (CT). CT revealed gastrointestinal abnormalities in 20 patients. In ten, lesion were identified by upper G-I series, in 15 by small bowel series, and in addition, in 3 by colon enema. The most common malignant small bowel tumor was adenocarcinoma (N=15) and was next common lymphoma (N=7). On barium study, primary adenocarcinoma appeared as an irregular stricture (66.7%) and polypoid mass with intussusception was most prominent finding in lymphoma. Leiomyosarcoma appeared as an exophytic mass with excavation or ulceration. CT was found to be accurate in detecting wall thickening, complications and other associated findings. In conclusion, barium study was useful in the diagnosis of primary malignant small bowel tumor and CT was more accurate in detecting secondary findings.

Full Text Available In the era of double balloon enteroscopy, capsule endoscopy, CT, and MRI enterography is transabdominal ultrasonography (TUS underestimated method for evaluation of small bowel pathology. As often initial imagine method in abdominal complaints, nowadays has TUS much better diagnostic potential than two decades ago. High-resolution ultrasound probes with harmonic imaging significantly improve resolution of bowel wall in real time, with possibility to asses bowel peristalsis. Color flow doppler enables evaluation of intramural bowel vascularisation, pulse wave doppler helps to quantificate flow in coeliac and superior mesenteric arteries. Small intestine contrast ultrasonography with oral contrast fluid, as well as contrast enhanced ultrasonography with intravenous microbubble contrast also improves small bowel imaging. We present a review of small intestine pathology that should be detected during ultrasound examinations, discuss technical requirements, advantages and limitations of TUS, typical ultrasound signs of Crohn's disease, ileus, celiac disease, intussusception, infectious enteritis, tumours, ischemic and haemorrhagic conditions of small bowel. In the hands of experienced investigator, despite some significant limitations(obesity, meteorism, is transabdominal ultrasonography reliable, noninvasive and inexpensive alternative method to computerised tomography (CT and magnetic resonance imaging (MRI in small bowel examination.

Sufficient luminal distension is mandatory for small bowel imaging. However, patients often are unable to ingest volumes of currently applied oral contrast compounds. The aim of this study was to evaluate if administration of low doses of an oral contrast agent with high-osmolarity leads to sufficient and diagnostic bowel distension. Six healthy volunteers ingested at different occasions 150, 300 and 450 ml of a commercially available oral contrast agent (Banana Smoothie Readi-Cat, E-Z-EM; 194 mOsmol/l). Two-dimensional TrueFISP data sets were acquired in 5-min intervals up to 45 min after contrast ingestion. Small bowel distension was quantified using a visual five-grade ranking (5 very good distension, 1 = collapsed bowel). Results were statistically compared using a Wilcoxon-Rank test. Ingestion of 450 ml and 300 ml resulted in a significantly better distension than 150 ml. The all-over average distension value for 450 ml amounted to 3.4 (300 ml: 3.0, 150 ml: 2.3) and diagnostic bowel distension could be found throughout the small intestine. Even 45 min after ingestion of 450 ml the jejunum and ileum could be reliably analyzed. Small bowel imaging with low doses of contrast leads to diagnostic distension values in healthy subjects when a high-osmolarity substance is applied. These findings may help to further refine small bowel MRI techniques, but need to be confirmed in patients with small bowel disorders. (orig.)

Full Text Available Surgery, Antibiotics, Facial cleanliness and Environmental improvement (SAFE are advocated by the World Health Organization (WHO for trachoma control. However, few studies have evaluated the complete SAFE strategy, and of these, none have investigated the associations of Antibiotics, Facial cleanliness, and Environmental improvement (A,F,E interventions and active trachoma. We aimed to investigate associations between active trachoma and A,F,E interventions in communities in Southern Sudan.Surveys were undertaken in four districts after 3 years of implementation of the SAFE strategy. Children aged 1-9 years were examined for trachoma and uptake of SAFE assessed through interviews and observations. Using ordinal logistic regression, associations between signs of active trachoma and A,F,E interventions were explored. Trachomatous inflammation-intense (TI was considered more severe than trachomatous inflammation-follicular (TF. A total of 1,712 children from 25 clusters (villages were included in the analysis. Overall uptake of A,F,E interventions was: 53.0% of the eligible children had received at least one treatment with azithromycin; 62.4% children had a clean face on examination; 72.5% households reported washing faces of children two or more times a day; 73.1% households had received health education; 44.4% of households had water accessible within 30 minutes; and 6.3% households had pit latrines. Adjusting for age, sex, and district baseline prevalence of active trachoma, factors independently associated with reduced odds of a more severe active trachoma sign were: receiving three treatments with azithromycin (odds ratio [OR] = 0.1; 95% confidence interval [CI] 0.0-0.4; clean face (OR = 0.3; 95% CI 0.2-0.4; washing faces of children three or more times daily (OR = 0.4; 95% CI 0.3-0.7; and presence and use of a pit latrine in the household (OR = 0.4; 95% CI 0.2-0.9.Analysis of associations between the A,F,E components of the SAFE strategy and

Full Text Available Aim: the main objective of this study was to investigate bowels impairment due to treatment with antibiotics, its incidence and clinical peculiarities; to evaluate its role in appearance of in irritable bowel syndrome. Material and Methods. We studied 110 patients (33 males and 77 females, age range 16-83 years, who received treatment with antibiotic. We evaluated the function of the intestine before treatment with antibiotic, then in 1 week, 3 months after treatment finish (1, 2, 3, 4 visits respectively. Control group included 20 healthy persons, who haven't had antibiotics administered during recent two years. Results. We revealed that the signs of bowel function impairment took place at the first visit in 18.2% of patients, at the second visit – in 60.0% of patients, at the third visit – in 45.5% of patients and at the fourth visit – in 41.1% of patients. At the second, third and fourth visits the signs of bowels function impairment were observed reliably more often then at the first visit (before antibiotic administration, p<0.001. At the second visit the signs bowels function disorders were the most prominent: abdominal pain – in 44.5%, distention – in 46.4%, diarrhea – in 29.1%, constipation – in 18.2%, presence of both (diarrhea and periodically constipation manifestations – in 2.7%; and extraintestinal manifestations (depression. depressed mood, sorrow, apathy, decreased stamina, sleep disturbances – in 29.1% of patients. Clinical manifestations of irritable bowel syndrome occured in 6 months of observation in 32.2% of patients. Conclusions. The signs of bowel function impairment were observed in 60.0% of patients after finishing treatment with antibiotic. This incidence is much higher than in control group (р<0.001. Bowel disorders mostly manifested as the changes in quantity and consistency of feaces, pain, abdominal distention and extraintestinal manifestations. In 32.2% of patients clinical manifestations of

Full Text Available Short bowel syndrome most commonly result after bowel resection for necrosis of the bowel. It may be caused by arterial or venous thrombosis, volvolus and in children, necrotizing enterocolitis. The other causes are Crohn,s disease intestinal atresia. The factors influencing the risk on short bowel syndrome are the remaining length of the small bowel, the age of onset, the length of the colon, the presence or absence of the ileo-coecal valve and the time after resection. Besides nutritional deficiencies there some other consequences of extensive resections of the small intestine (gastric acid hypersecretion, d-lactic acidosis, nephrolithiasis, cholelithiasis, which must be diagnosed, treated, and if possible, prevented. With current therapy most patients with short bowel have normal body mass index and good quality of life.

Volvulus of the intestines may involve either the small bowel or colon. In the pediatric population, small bowel volvulus is more common, while in the adult population, colonic volvulus is more often seen. The two most common types of colonic volvulus include sigmoid and cecal volvulus. Prompt diagnosis and treatment is imperative, otherwise bowel ischemia may ensue. Treatment often involves emergent surgical exploration and bowel resection. PMID:28144211

Two children with small bowel volvulus diagnosed on barium enema examination are reported. In one patient the volvulus was associated with malrotation and in the other patient there was a post-operative peritoneal adhesion. In both cases the diagnosis was based on beaking of the head of the barium column at the site of volvulus. Radiographic demonstration of a beak sign in the small bowel on barium enema examination should suggest a diagnosis of small bowel volvulus, and indicates the need for immediate surgery. (orig.) [de

The efficacy of discharge cleaning and disinfection of high-touch surfaces of intensive care unit patient rooms in Brazil, Canada, the Netherlands, and the United States was evaluated and the effect of an educational intervention was determined. Significant site-to-site differences in cleaning regimens and baseline cleanliness levels were observed using ATP levels, colony-forming units, and reflective surface marker removal percent pass rates. An educational intervention that includes rapid feedback of the ATP measurements could significantly improve the quality of the cleaning and disinfection regimens.

The objective is to use multidetector computed tomography (MDCT) to differentiate phytobezoar impaction and small-bowel faeces in patients with small-bowel obstruction (SBO). We retrospectively reviewed 91 consecutive SBO patients with surgically proven phytobezoars (n = 31) or adhesion with small-bowel faeces (n = 60). Two readers blinded to the diagnosis recorded the following MDCT features: degree of obstruction, transition point, mesenteric fatty stranding, intraperitoneal fluid, air-fluid level, pneumatosis intestinalis, and portal venous gas. MDCT measurements of the food debris length, attenuation, luminal diameter, and wall thickness of the obstructed bowel were also compared. A higher grade of obstruction with an absence of mesenteric fatty stranding and intraperitoneal fluid was more commonly seen in the phytobezoar group than in the small-bowel faeces group (p < 0.01). The food debris length (phytobezoar, 5.7 ± 2.8 cm; small-bowel feces, 20.3 ± 7.9 cm, p < 0.01) and mean attenuation (phytobezoar, -59.6 ± 43.3 Hounsfield units (HU); small-bowel faeces, 8.5 ± 7.7 HU, p <0.01) were significantly different between the two groups. The ROC curve showed that food debris length <9.5 cm and mean attenuation value < -11.75 HU predicted phytobezoar impaction. MDCT features with measurements of the food debris length and mean attenuation assist the differentiation of phytobezoar impaction and small-bowel faeces. (orig.)

To assess the effect of the osmolarity for small bowel distension in MRI, ten volunteers ingested at two separate occasions negative oral contrast agents with different quantity and osmolarity: (1) a water solution combined with 2.0% sorbitol and 0.2% locus bean gum (LBG) with a quantity of 1500 ml and an osmolarity of 148 mOsmol/l, (2) a water solution combined with 2.0% sorbitol and 2.0% barium sulphate with a quantity of 1000 ml and an osmolarity of 194 mOsmol/l. Small bowel distension was quantified on coronal 2D-TrueFISP images by measuring the small bowel diameters. There were no statistically significant differences in mean small bowel diameter between both contrast agents. The mean small bowel distension was 19.2 mm after ingestion of 1500 ml of sorbitol-LBG solution and 19.0 mm after ingestion of 1000-ml sorbitol-barium sulphate solution. Furthermore, all volunteers found the ingestion of 1000-ml solution more pleasant than the 1500-ml solution. The ingestion of 1000 ml of sorbitol-barium sulphate solution led to a sufficient small bowel distension compared to 1500 ml of sorbitol-LBG solution. The side effect rate of both solutions was low. Based on these data, we recommend a quantity of 1000 ml of sorbitol-barium sulphate solution as an alternative for 1500-ml sorbitol-LBG solution for optimal bowel distension. (orig.)

Irritable bowel syndrome is a complex disorder whose pathophysiology involves alterations in the enteric microbiota, visceral hypersensitivity, gut immune/barrier function, hypothalamic-pituitary-adrenal axis regulation, neurotransmitters, stress response, psychological factors, and more. The importance of diet in the management of irritable bowel syndrome has taken center stage in recent times as the literature validates the relationship of certain foods with the provocation of symptoms. Likewise, a number of elimination dietary programs have been successful in alleviating irritable bowel syndrome symptoms. Knowledge of the dietary management strategies for irritable bowel syndrome will help guide nutritionists and healthcare practitioners to deliver optimal outcomes.

Short bowel syndrome.

2012-02-01

The short bowel syndrome (SBS) is a state of malabsorption following intestinal resection where there is less than 200 cm of intestinal length. The management of short bowel syndrome can be challenging and is best managed by a specialised multidisciplinary team. A good understanding of the pathophysiological consequences of resection of different portions of the small intestine is necessary to anticipate and prevent, where possible, consequences of SBS. Nutrient absorption and fluid and electrolyte management in the initial stages are critical to stabilisation of the patient and to facilitate the process of adaptation. Pharmacological adjuncts to promote adaptation are in the early stages of development. Primary restoration of bowel continuity, if possible, is the principle mode of surgical treatment. Surgical procedures to increase the surface area of the small intestine or improve its function may be of benefit in experienced hands, particularly in the paediatric population. Intestinal transplant is indicated at present for patients who have failed to tolerate long-term parenteral nutrition but with increasing experience, there may be a potentially expanded role for its use in the future.

Aim The aim of this meta-analysis was to analyze the efficacy and safety of antidepressants for the treatment of irritable bowel syndrome. Methods We searched MEDLINE, EMBASE, Scopus and The Cochrane Library for randomized controlled trials investigating the efficacy and safety of antidepressants in the treatment of irritable bowel syndrome. Article quality was evaluated by Jadad score. RevMan 5.0 and Stata 12.0 were used for the meta-analysis. Results Twelve randomized controlled trials were included in this study and most of these trials were of high quality (Jadad score ≥4). Five articles focused on tricyclic antidepressants, six articles involved selective serotonin reuptake inhibitors, and one article investigated both types of treatment. The pooled risk ratio showed antidepressant treatment can improve global symptoms (RR = 1.38, 95% CI 1.08, 1.77). In the subgroup analysis, treatment with tricyclic antidepressants showed an improvement in global symptoms (RR = 1.36, 95% CI 1.07, 1.71), while treatment with selective serotonin reuptake inhibitors showed no statistically significant difference in global symptoms compared with the control groups (RR = 1.38, 95% CI 0.83, 2.28). The pooled risk ratio of dropout due to side effects following antidepressant treatment was 1.71 with 95% CI (0.98, 2.99). The subgroup analysis showed the pooled risk ratio of dropout in the tricyclic antidepressants group was 1.92 with 95% CI (0.89, 4.17). In the selective serotonin reuptake inhibitors group, the pooled risk ratio of dropout was 1.5 with 95% CI (0.67, 3.37). Selective serotonin reuptake inhibitors showed no benefit in alleviating abdominal pain and improving quality of life. There was no difference in the incidence of common adverse events between treatment and control groups. Conclusions TCAs can improve global symptoms of irritable bowel syndrome, while there was no strong evidence to confirm the effectiveness of SSRIs for the treatment of IBS. PMID:26252008

Neurobiology of Depression and Irritable Bowel Syndrome Comorbidity

Full Text Available Irritable bowel syndrome is a disabling functional disorder with a frequent comorbidity of depression though underlying mechanisms remain yet little understood. Various signs and symptoms have been determined as diagnostic criteria in recent years and standardized as Rome-III criteria. Irritable bowel syndrome can have constipation-dominant, diarrhea-dominant or mixed clinical presentations. Main features can be summarized as continuous and recurrent abdominal pain or discomfort associated with a change of stool frequency or consistency and usually relief of symptoms with defe-cation in the absence of physical or laboratory abnormalities indicative of an organic etiology. The frequency of major depressive disorder diagnosis reaches up to two thirds of irritable bowel syndrome patients. Moreover, the comorbidity of irritable bowel syndrome among patients with major depression is highly frequent (30%. The mechanism underlying irritable bowel syndrome which have been considered as a kind of a somatization disorder for a long time and now as a functional bowel disease is in the brain-gut axis. Low grade mucosal inflammation and cytokines originating from mucosal inflammation have important functions in the pathophysiology of irritable bowel syndrome and its comorbidity with major depression. Besides the inflammatory factors lumbosacral visceral hyperexcitability which is an individual variation is proposed as the main underlying cause of irritable bowel syndrome. Visceral hyper-excitability is mediated by cytokines and neuro-mediators and stress is known to increase the effect of this mechanism. Furthermore, molecules participating in this mechanism (e.g. cytokines, corticotrophin releasing factor, neurokinins and monoamines play important roles in the pathophysiology of depression. Increased activation in the pain matrix (thalamus – insula – prefrontal cortex and insufficiency of endogenous pain inhibitory system are regarded as possible

Muscarinic acetylcholine receptor expression in aganglionic bowel.

In Hirschsprung's disease (HD) there exists an overabundance of acetylcholine (ACh), which in turn stimulates excessive production of the enzyme acetylcholinesterase. Muscarinic ACh receptors (mAChRs) play an important role in smooth-muscle contraction. Recent studies have indicated five different subtypes of mAChRs encoded by five different genes, ml to m5. The purpose of this study was to investigate the expression of each mAChR subtype in aganglionic (AG) colon to further understand the pathophysiology of HD. Entire colon resected at the time of pull-through operation for HD was obtained from 14 patients. Specimens obtained at autopsy from 8 age-matched patients without gastrointestinal disease acted as controls. Frozen sections were used for indirect immunohistochemistry as well as in-situ hybridization. Immunohistochemistry was performed using specific antiserum against each mAChR subtype and in-situ hybridization was performed using specific oligonucleotide probes against ml to m5 subtypes. Messenger RNA (mRNA) was extracted from normoganglionic (NG) and AG bowel of HD patients and normal control bowel. Reverse transcription-polymerase chain reaction was performed to evaluate mRNA levels of each mAChR subtype. To adjust the levels of mRNA expression, a housekeeping gene G3PDH, known to be expressed normally, was used as an internal control. Strong m2 and m3 immunoreactivity was observed in the mucosal layer, smooth-muscle layers, and myenteric plexus of NG bowel, whereas ml immunoreactivity was only detected in the mucosal layer. The most striking finding was the abundance of m3-immunoreactive fibers in muscle layers of NG bowel while there was a total lack of m3 fibers in smooth-muscle of AG bowel. Intense mRNA signals encoding m2 and m3 and to a lesser degree ml were detected in NG bowel, and these signals were weak in AG bowel. Immunoreactivity and mRNA expression of m4 and m5 was not detected in NG or AG bowel. The lack of m3-immunoreactive fibers in the

Though a number of CT findings of bowel and mesenteric injuries in blunt abdominal trauma are described in literature, no studies on the specific CT signs of a transected bowel have been published. In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma. We investigated the incidence of bowel transection in 513 patients admitted for blunt abdominal trauma who underwent multidetector CT (MDCT). The MDCT findings of 8 patients with a surgically proven complete bowel transection were assessed retrospectively. We report novel CT signs that are unique for transection, such as complete cutoff sign (transection of bowel loop), Janus sign (abnormal dual bowel wall enhancement, both increased and decreased), and fecal spillage. The incidence of bowel transection in blunt abdominal trauma was 1.56%. In eight cases of bowel transection, percentage of CT signs unique for bowel transection were as follows: complete cutoff in 8 (100%), Janus sign in 6 (100%, excluding duodenal injury), and fecal spillage in 2 (25%). The combination of complete cutoff and Janus sign were highly specific findings in patients with bowel transection. Complete cut off and Janus sign are the unique CT findings to help detect bowel transection in blunt abdominal trauma and recognition of these findings enables an accurate and prompt diagnosis for emergency laparotomy leading to reduced mortality and morbidity.

Bowel rotation abnormalities in heterotaxy are common. As more children survive cardiac surgery, the management of gastrointestinal abnormalities has become controversial. To evaluate imaging of malrotation in heterotaxy with surgical correlation and provide an algorithm for management. Imaging reports of heterotaxic children with upper gastrointestinal (UGI) and/or small bowel follow-through (SBFT) were reviewed. Subsequently, fluoroscopic images were re-reviewed in conjunction with CT/MR studies. The original reports and re-reviewed images were compared and correlated with surgical findings. Nineteen of 34 children with heterotaxy underwent UGI, 13/19 also had SBFT. In 15/19 reports, bowel rotation was called abnormal: 11 malrotation, 4 non-rotation, no cases of volvulus. Re-review, including CT (10/19) and MR (2/19), designated 17/19 (90%) as abnormal, 10 malrotation (abnormal bowel arrangement, narrow or uncertain length of mesentery) and 7 non-rotation (small bowel and colon on opposite sides plus low cecum with probable broad mesentery). The most useful CT/MR findings were absence of retroperitoneal duodenum in most abnormal cases and location of bowel, especially cecum. Abnormal orientation of mesenteric vessels suggested malrotation but was not universal. Nine children had elective bowel surgery; non-rotation was found in 4/9 and malrotation was found in 5/9, with discrepancies (non-rotation at surgery, malrotation on imaging) with 4 original interpretations and 1 re-review. We recommend routine, early UGI and SBFT studies once other, urgent clinical concerns have been stabilized, with elective laparoscopic surgery in abnormal or equivocal cases. Cross-sectional imaging, usually obtained for other reasons, can contribute diagnostically. Attempting to assess mesenteric width is important in differentiating non-rotation from malrotation and more accurately identifies appropriate surgical candidates. (orig.)

This prospective study aims to evaluate the efficacy of multislice computed tomography combined with colon distension by water enteroclysis (MSCTe) in determining the presence and depth of bowel endometriotic lesions. Ninety-eight women with symptoms suggestive of colorectal endometriosis underwent MSCTe; locations, number of nodule/s, size of the nodule/s and depth of bowel wall infiltration were determined. Independently from the findings of MSCTe, all women underwent laparoscopy. MSCTe findings were compared with surgical and histological results. Abnormal findings suggestive of bowel endometriotic nodules were detected by MSCTe in 75 of the 76 patients with bowel endometriosis. MSCTe identified 110 (94.8%) of the 116 bowel endometriotic nodules removed at surgery; 6 nodules missed at MSCTe were located on the rectum. MSCTe correctly determined the degree of infiltration of the bowel wall in all of the 34 serosal bowel nodules identified at MSCTe. In six nodules reaching the submucosa, the depth of infiltration was underestimated by MSCTe. MSCTe had a sensitivity of 98.7%, a specificity of 100%, a positive predictive value of 100% and a negative predictive value of 95.7% in identifying women with bowel endometriosis. MSCTe is effective in determining the presence and depth of bowel endometriotic lesions. (orig.)

2012-09-07

To determine the value of bowel sounds analysis using an electronic stethoscope to support a clinical diagnosis of intestinal obstruction. Subjects were patients who presented with a diagnosis of possible intestinal obstruction based on symptoms, signs, and radiological findings. A 3M™ Littmann(®) Model 4100 electronic stethoscope was used in this study. With the patients lying supine, six 8-second recordings of bowel sounds were taken from each patient from the lower abdomen. The recordings were analysed for sound duration, sound-to-sound interval, dominant frequency, and peak frequency. Clinical and radiological data were reviewed and the patients were classified as having either acute, subacute, or no bowel obstruction. Comparison of bowel sound characteristics was made between these subgroups of patients. In the presence of an obstruction, the site of obstruction was identified and bowel calibre was also measured to correlate with bowel sounds. A total of 71 patients were studied during the period July 2009 to January 2011. Forty patients had acute bowel obstruction (27 small bowel obstruction and 13 large bowel obstruction), 11 had subacute bowel obstruction (eight in the small bowel and three in large bowel) and 20 had no bowel obstruction (diagnoses of other conditions were made). Twenty-five patients received surgical intervention (35.2%) during the same admission for acute abdominal conditions. A total of 426 recordings were made and 420 recordings were used for analysis. There was no significant difference in sound-to-sound interval, dominant frequency, and peak frequency among patients with acute bowel obstruction, subacute bowel obstruction, and no bowel obstruction. In acute large bowel obstruction, the sound duration was significantly longer (median 0.81 s vs 0.55 s, P = 0.021) and the dominant frequency was significantly higher (median 440 Hz vs 288 Hz, P = 0.003) when compared to acute small bowel obstruction. No significant difference was seen

The research progress of acute small bowel perforation

Directory of Open Access Journals (Sweden)

Rudolf Schiessel

2015-08-01

Full Text Available This article reviews the various aetiologies of small bowel perforations and their management. In addition to the well-known aetiologies such as trauma, inflammation and circulatory disorders, several new causes of small bowel perforation have been described in recent years. The spectrum reaches from iatrogenic perforations during laparoscopic surgery or enteroscopies to drug-induced perforations with new anticancer agents. The management of small bowel perforations requires a concept consisting of the safe revision of the leaking bowel and the treatment of the peritonitis. Depending on the local situation and the condition of the patient, several treatment options are available. The surgical management of the bowel leak can range from a simple primary closure to a delayed restoration of bowel continuity. When the condition of the bowel or patient is frail, the risk of a failure of a closure or anastomosis is too high, and the exteriorization of the bowel defect as a primary measure is a safe option. The treatment of the peritonitis is also dependent on the condition of the patient and the local situation. Early stages of peritonitis can be treated by a simple peritoneal lavage, either performed by laparoscopy or laparotomy. Severe forms of peritonitis with multi-organ failure and an abdominal compartment syndrome need repeated peritoneal revisions. In such cases, the abdomen can only be closed temporarily. Different technical options are available in order to overcome the difficult care of these patients.

Felder, Seth; Margel, David; Murrell, Zuri; Fleshner, Phillip

2014-01-01

Although the auscultation of bowel sounds is considered an essential component of an adequate physical examination, its clinical value remains largely unstudied and subjective. The aim of this study was to determine whether an accurate diagnosis of normal controls, mechanical small bowel obstruction (SBO), or postoperative ileus (POI) is possible based on bowel sound characteristics. Prospectively collected recordings of bowel sounds from patients with normal gastrointestinal motility, SBO diagnosed by computed tomography and confirmed at surgery, and POI diagnosed by clinical symptoms and a computed tomography without a transition point. Study clinicians were instructed to categorize the patient recording as normal, obstructed, ileus, or not sure. Using an electronic stethoscope, bowel sounds of healthy volunteers (n = 177), patients with SBO (n = 19), and patients with POI (n = 15) were recorded. A total of 10 recordings randomly selected from each category were replayed through speakers, with 15 of the recordings duplicated to surgical and internal medicine clinicians (n = 41) blinded to the clinical scenario. The sensitivity, positive predictive value, and intra-rater variability were determined based on the clinician's ability to properly categorize the bowel sound recording when blinded to additional clinical information. Secondary outcomes were the clinician's perceived level of expertise in interpreting bowel sounds. The overall sensitivity for normal, SBO, and POI recordings was 32%, 22%, and 22%, respectively. The positive predictive value of normal, SBO, and POI recordings was 23%, 28%, and 44%, respectively. Intra-rater reliability of duplicated recordings was 59%, 52%, and 53% for normal, SBO, and POI, respectively. No statistically significant differences were found between the surgical and internal medicine clinicians for sensitivity, positive predictive value, or intra-rater variability. Overall, 44% of clinicians reported that they rarely listened

Changing face of irritable bowel syndrome

Recent years have witnessed tremendous progress in our understanding of irritable bowel syndrome (IBS). It is evident that this is a truly global disease associated with significant symptoms and impairments in personal and social functioning for afflicted individuals. Advances in our understanding of gut flora-mucosal interactions, the enteric nervous system and the brain-gut axis have led to substantial progress in the pathogenesis of symptoms in IBS and have provided some hints towards the basic etiology of this disorder, in some subpopulations, at the very least. We look forward to a time when therapy will be addressed to pathophysiology and perhaps, even to primary etiology. In the meantime, a model based on a primary role for intestinal inflammation serves to integrate the various strands, which contribute to the presentation of IBS

Is irritable bowel syndrome an infectious disease?

Science.gov (United States)

Thompson, John Richard

2016-01-28

Irritable bowel syndrome (IBS) is the most common of all gastroenterological diseases. While many mechanisms have been postulated to explain its etiology, no single mechanism entirely explains the heterogeneity of symptoms seen with the various phenotypes of the disease. Recent data from both basic and clinical sciences suggest that underlying infectious disease may provide a unifying hypothesis that better explains the overall symptomatology. The presence of small intestinal bowel overgrowth (SIBO) has been documented in patients with IBS and reductions in SIBO as determined by breath testing correlate with IBS symptom improvement in clinical trials. The incidence of new onset IBS symptoms following acute infectious gastroenteritis also suggests an infectious cause. Alterations in microbiota-host interactions may compromise epithelial barrier integrity, immune function, and the development and function of both central and enteric nervous systems explaining alterations in the brain-gut axis. Clinical evidence from treatment trials with both probiotics and antibiotics also support this etiology. Probiotics appear to restore the imbalance in the microflora and improve IBS-specific quality of life. Antibiotic trials with both neomycin and rifaximin show improvement in global IBS symptoms that correlates with breath test normalization in diarrhea-predominant patients. The treatment response to two weeks of rifaximin is sustained for up to ten weeks and comparable results are seen in symptom reduction with retreatment in patients who develop recurrent symptoms.

Automatic Bowel Motility Evaluation Technique for Noncontact Sound Recordings

Directory of Open Access Journals (Sweden)

2018-06-01

Full Text Available Information on bowel motility can be obtained via magnetic resonance imaging (MRIs and X-ray imaging. However, these approaches require expensive medical instruments and are unsuitable for frequent monitoring. Bowel sounds (BS can be conveniently obtained using electronic stethoscopes and have recently been employed for the evaluation of bowel motility. More recently, our group proposed a novel method to evaluate bowel motility on the basis of BS acquired using a noncontact microphone. However, the method required manually detecting BS in the sound recordings, and manual segmentation is inconvenient and time consuming. To address this issue, herein, we propose a new method to automatically evaluate bowel motility for noncontact sound recordings. Using simulations for the sound recordings obtained from 20 human participants, we showed that the proposed method achieves an accuracy of approximately 90% in automatic bowel sound detection when acoustic feature power-normalized cepstral coefficients are used as inputs to artificial neural networks. Furthermore, we showed that bowel motility can be evaluated based on the three acoustic features in the time domain extracted by our method: BS per minute, signal-to-noise ratio, and sound-to-sound interval. The proposed method has the potential to contribute towards the development of noncontact evaluation methods for bowel motility.

Strouse, Peter J.; DiPietro, Michael A.; Saez, Fermin

2003-01-01

To determine the frequency and significance of small-bowel intussusception identified in children on CT. All abdomen CT reports between July 1995 and April 2002 were reviewed to identify patients with small-bowel intussusception. Intussusceptions were identified as an intraluminal mass with a characteristic layered appearance and/or continuity with adjacent mesenteric fat. Ileocolic intussusceptions and intussusceptions related to feeding tubes were excluded. Imaging studies and medical records were reviewed. Twenty-five pediatric patients (16 boys, 9 girls; mean age 11.2 years) were identified with small-bowel intussusception on CT. No patient had a persistent intussusception requiring surgery. Fourteen had limited immediate repeat CT images as part of the same examination, ten of which demonstrated resolution of the CT abnormality. Follow-up CT [n=13 (6 within 24 h)], ultrasound (n=3), small-bowel follow-through (n=4) and surgery (n=3) showed no intussusception. In four patients with persistent symptoms, underlying pathology was identified requiring treatment (giardiasis, 2; small-bowel inflammation/strictures, 1; abscess and partial small-bowel obstruction after perforated appendicitis, 1). In 21 other patients, direct correlation of symptoms to CT abnormality was absent or questionable, no treatment was required, and there was no clinical or imaging evidence of persistence or recurrence. Most small-bowel intussusceptions identified in children by CT are transient and of no clinical significance. (orig.)

Cleanliness in context: reconciling hygiene with a modern microbial perspective.

The concept of hygiene is rooted in the relationship between cleanliness and the maintenance of good health. Since the widespread acceptance of the germ theory of disease, hygiene has become increasingly conflated with sterilization. In reviewing studies across the hygiene literature (most often hand hygiene), we found that nearly all studies of hand hygiene utilize bulk reduction in bacterial load as a proxy for reduced transmission of pathogenic organisms. This treatment of hygiene may be insufficient in light of recent microbial ecology research, which has demonstrated that humans have intimate and evolutionarily significant relationships with a diverse assemblage of microorganisms (our microbiota). The human skin is home to a diverse and specific community of microorganisms, which include members that exist across the ecological spectrum from pathogen through commensal to mutualist. Most evidence suggests that the skin microbiota is likely of direct benefit to the host and only rarely exhibits pathogenicity. This complex ecological context suggests that the conception of hygiene as a unilateral reduction or removal of microbes has outlived its usefulness. As such, we suggest the explicit definition of hygiene as "those actions and practices that reduce the spread or transmission of pathogenic microorganisms, and thus reduce the incidence of disease."

To evaluate CT findings for the differential diagnosis of mechanical bowel obstruction and paralytic ileus. Without information relating to clinical or operative findings, we retrospectively analyzed the CT scans of 24 patients with mechanical bowel obstruction and 19 patients with paralytic ileus. Final diagnosis was confirmed by operation (n=26), or by clinical symptoms, radiologic findings and follow-up study CT findings were obtained:1) the diameter of the most dilated part of the small bowel, and the thickness and enhancing pattern of the dilated small bowel wall;2) the diameter of the most dilated part of the descending colon and the ratio of the diameter of the small bowel to that of the descending colon;3) the number of transitional zones, length and thickness and 4) associated ascites and its location. The mean diameters of the most dilated part of the small bowel in mechanical bowel obstruction and paralytic ileus were 3.6cm and 2.9cm, respectively. The diameter of the small bowel in mechanical bowel obstruction was significantly greater than in paralytic ileus(p<.05). The mean thickness of dilated small bowel wall was 4.0mm in mechanical bowel obstruction and 2.4mm in paralytic ileus, and target-like enhancement was prominent in mechanical bowel obstruction(46%)(p<.05). The mean diameter of the most dilated part of the descending colon was not significantly different to that of the most dilated part of the small bowel, but the ratio of the diameter of the small bowel to that of the colon was 2.9 in mechanical bowel obstruction and 1.9 in paralytic ileus, respectively, which was statistically significant(p<.05). A transitional zone was seen in 23 cases(96%) of mechanical bowel obstruction and in nine (47%) of paralytic ileus. In mechanical bowel obstruction, mean transitional zone length was 2cm, shorter than that of paralytic ileus(3.4cm)(p<.05) The thickness of transitional zone and the presence of ascites and its locations were not significantly

Surgical treatment of bowel occlusion as late radiation effect

67 patients were operated for intestinal complications following radiotherapy. The lesions were located in the small bowel (n = 41) and in the sigmoid colon/rectum (n = 33). 98.5% of the patients were females, the most frequent cause for irradiation being ovarian cancer. Bowel stenosis with resultant chronic or acute ileus was the most frequent indication for operation. Percutaneous irradiation resulted in a significantly higher proportion of small bowel lesions (77%, p = 0.001), whilst endocavitary irradiation was followed in 67% of cases by colorectal lesions. Different application modality of irradiation also resulted in completely different symptoms for small and large bowel lesions. The operative mortality was 9.5%. Peritonitis following anastomotic leakage was the cause of death in 6 of 7 cases. In the treatment of small bowel ileus mortality following bowel resection (9%, one of 11 cases) was comparable to that of the bypass operation (6%, one of 18 cases). Both operation methods seem to be justified. Single-layer anastomosis resulted in zero mortality (21 cases) for ileus operation compared with 19% mortality (16 cases) in double-layer anastomosis and should be prefered for operations on the irradiated bowel.

To investigate the potential efficacy of bowel cancer prevention messages in increasing intentions to be more physically active. A convenience sample of 281 physically inactive persons aged 30-60 years was recruited in the Perth city centre and randomly assigned to a bowel cancer and physical activity message or a heart disease and physical activity message. After reading a booklet containing information about physical activity and its link either to bowel cancer (n = 141) or cardiovascular disease (n = 140), respondents filled in a self-completion questionnaire. The main response measures were impact on intentions to be more physically active, and perceived believability and relevance of the message. Perceived believability of the message was high in both conditions. Perceived personal relevance of the message was substantially lower in the bowel cancer than the cardiovascular disease condition. Overall, the cardiovascular disease condition achieved somewhat higher behavioural intentions than the bowel cancer condition. The finding that two in three respondents in the bowel cancer condition had increased intention to increase their level of physical activity provides support for the potential efficacy of promoting physical activity in reducing the risk of bowel cancer.

Nevedal, Andrea; Kratz, Anna L; Tate, Denise G

2016-01-01

Neurogenic bladder and bowel (NBB) is a chronic condition hindering the functioning and quality of life (QOL) of people with spinal cord injury (SCI). NBB research has focused on men with SCI leaving unanswered questions about women's experiences of living with NBB. The purpose of this study was to identify and describe women's experiences of living with SCI and NBB. Secondary analysis of semi-structured interviews from a larger qualitative study of women with SCI (N = 50) was carried out. Transcripts were coded for bowel and bladder content. Pile-sorting techniques were used to identify emergent themes related to NBB. Meta-themes were categorized under the International Classification of Functioning, Disability and Health. Bladder and bowel topics were spontaneously discussed by 46 out of 50 study participants suggesting the salience of this issue for women with SCI. We identified 6 meta-themes: life controlled by bladder and bowel, bladder and bowel accidents, women's specific challenges, life course disruption, bladder and bowel medical management, and finding independence. Findings describe concerns, strategies, and the detrimental impact of NBB in the lives of women with SCI. Findings inform policy makers, health care and rehabilitation professionals to improve accessibility and quality of life for women with NBB. Women with spinal cord injury (SCI) reported gender specific challenges to living with neurogenic bladder and bowel (NBB). Interventions designed for women with SCI can address these problems and provide recommendations for prevention and treatment. Women described the detrimental impact of NBB on life course expectations, emotional, social, physical health, and quality of life domains. Psychosocial and educational programs can be developed to address these challenges and improve overall quality of life. Recommendations for special treatment and policy considerations are needed to maximize women's independence and health while living with NBB

Postoperative traditional feeding protocols are not based on scientific studies, but rather on anecdotal evidence. We present the first prospective trial of aggressive postoperative bowel stimulation following radical hysterectomy in an attempt to determine its effect on the length of hospital stay. Twenty consecutive patients undergoing radical hysterectomy were entered onto a prospective trial of aggressive postoperative bowel stimulation, which consisted of 30 cc milk of magnesia p.o. b.i.d. starting on postoperative day 1 and biscolic suppositories q.d. starting on day 2. A clear liquid diet was begun following flatus or bowel movement and patients were discharged 12 h after tolerating a clear liquid diet. Diet was slowly advanced at home. Median time to flatus was 3 days, bowel movement 3 days, and clear liquid diet 3 days. Median time to discharge was 4 days. No patients developed ileus or bowel obstructions and there were no readmissions for bowel complications. Our median time to discharge of 4 days represents a 50% reduction in hospital stay compared to our previous prospective study using traditional postoperative bowel management (8 days), which was statistically significant at P = 0.001. Aggressive bowel stimulation with milk of magnesia and biscolic suppositories resulted in early return of bowel function and early discharge with no noticeable complications.

Full Text Available Abstract Background Radiological scoring methods such as colon transit time (CTT have been widely used for the assessment of bowel motility. However, these radiograph-based methods need cumbersome radiological instruments and their frequent exposure to radiation. Therefore, a non-invasive estimation algorithm of bowel motility, based on a back-propagation neural network (BPNN model of bowel sounds (BS obtained by an auscultation, was devised. Methods Twelve healthy males (age: 24.8 ± 2.7 years and 6 patients with spinal cord injury (6 males, age: 55.3 ± 7.1 years were examined. BS signals generated during the digestive process were recorded from 3 colonic segments (ascending, descending and sigmoid colon, and then, the acoustical features (jitter and shimmer of the individual BS segment were obtained. Only 6 features (J1, 3, J3, 3, S1, 2, S2, 1, S2, 2, S3, 2, which are highly correlated to the CTTs measured by the conventional method, were used as the features of the input vector for the BPNN. Results As a results, both the jitters and shimmers of the normal subjects were relatively higher than those of the patients, whereas the CTTs of the normal subjects were relatively lower than those of the patients (p k-fold cross validation, the correlation coefficient and mean average error between the CTTs measured by a conventional radiograph and the values estimated by our algorithm were 0.89 and 10.6 hours, respectively. Conclusions The jitter and shimmer of the BS signals generated during the peristalsis could be clinically useful for the discriminative parameters of bowel motility. Also, the devised algorithm showed good potential for the continuous monitoring and estimation of bowel motility, instead of conventional radiography, and thus, it could be used as a complementary tool for the non-invasive measurement of bowel motility.

Endometriosis: A Rare Cause of Large Bowel Obstruction

Directory of Open Access Journals (Sweden)

Gonçalo Alexandrino

2017-10-01

Full Text Available Large bowel obstruction can result in significant morbidity and mortality, especially in cases of acute complete obstruction. There are many possible causes, the most common in adults being colorectal cancer. Endometriosis is a benign disease, and the most affected extragenital location is the bowel, especially the rectosigmoid junction. However, transmural involvement and acute occlusion are very rare events. We report an exceptional case of acute large bowel obstruction as the initial presentation of endometriosis. The differential diagnosis of colorectal carcinoma may be challenging, and this case emphasizes the need to consider intestinal endometriosis in females at a fertile age presenting with gastrointestinal symptoms and an intestinal mass causing complete large bowel obstruction.

A cross-cultural perspective on irritable bowel syndrome.

Gerson, Charles D; Gerson, Mary-Joan

2010-01-01

Irritable bowel syndrome is a functional gastrointestinal illness, defined by symptoms. Irritable bowel syndrome has been described as a biopsychosocial condition, in which colonic dysfunction is affected by psychological and social factors. As a result of this unusual constellation, irritable bowel syndrome may be subject to cultural variables that differ in different parts of the globe. In this article, we describe some of the ways in which irritable bowel syndrome may be experienced differently, depending on local belief systems, psychological pressures, acceptance or resistance to a mind-body paradigm, and breakdown in support or relationship structure. Examples are given in which irritable bowel syndrome investigators from countries around the world describe various aspects of the syndrome that may affect the illness experience of their patients. We describe our own research studies that have demonstrated possible adverse effects on disease severity from relationship conflict, attribution of symptoms to physical rather than emotional cause, and the belief that irritable bowel syndrome is enduring and mysterious. Also described is our finding that symptom patterns may differ significantly between different geographic locations. Finally, we discuss the importance of "cultural competence" on the part of healthcare professionals in regard to caring for patients of diverse cultural backgrounds. © 2010 Mount Sinai School of Medicine.

To compare small bowel distension and bowel wall visualization among three different patients' positions (supine, sitting and right decubitus) during administration of oral contrast media in preparation for CT enterography (CTE). A total of 150 consecutive patients (104 males and 46 females; mean age 34.6 years, range 15-78 years) who were scheduled to undergo CTE were recruited. Patients were randomly allocated into the three position groups during oral contrast media administration, and there were 50 patients in each group. Two blinded radiologists independently scored the luminal distension and visualization of the bowel wall using a continuous 5-point scale (1: worst and 5: best) at the jejunum and ileum. The Mann-Whitney U test was used to evaluate differences between any two groups among the three positions for bowel distension and wall visualization. For ileal distension, the supine and sitting positions performed better than the right decubitus position [for reader 1, mean: 3.4/3.2/2.9 (hereafter, supine/sitting/right decubitus in order), p = 0.002/0.033; for reader 2, 3.3/3.0/2.6, p 0.05, respectively). For bowel wall visualization, the supine and sitting positions were superior to the right decubitus position for the ileum when scored by one reader (4.0/3.8/3.4, p = 0.001/0.015). Supine and sitting positions during the administration of oral contrast media provided better ileal distension than the right decubitus position in obtaining CTE. Advances in knowledge: The performance of CTE largely depends on adequate luminal distension and wall visualization. As the terminal ileum is the predominant site of small bowel pathology for inflammatory bowel disease, the supine or sitting position would be preferable for patients who are suspected of having small bowel pathology.

Full Text Available Double balloon enteroscopy (DBE is a revolutionary procedure in which the entire small bowel can be visualized endoscopically. DBE has the advantage of both diagnostic and therapeutic capabilities in the setting of small bowel neoplasms and vascular malformations. We present a unique case of a 76-year-old female who underwent small bowel DBE tattoo marking of a distal small bowel tumor complicated by development of severe abdominal pain postprocedure secondary to bowel air embolism into the mesenteric veins. Mesenteric air can be seen after other endoscopic procedures such as biopsy, mucosal clip placement and polypectomy, or following a colonoscopy. Mesenteric air embolism following small bowel tattooing procedure has not been previously reported in the literature. Mesenteric air when present may be attributed to mesenteric ischemia and can subject the patient to unnecessary surgical intervention if misdiagnosed. Thus, this report holds significance for the radiologist as computed tomography (CT findings of mesenteric air embolism must be evaluated in the context of appropriate clinical history before treatment decisions are made.

Full Text Available Background and Objectives: Irritable bowel syndrome is one of the most common functional gastrointestinal disorders striking 10-20% of the world population. Although most patients do not take medical assistance, this disease enforces significant cost on the patient and health systems and has negative effects on quality of life of the individual. After diagnosis ,treatment of this disease is the next step. Many pathways of treatment has been introduced and the efficacy of each other has been established in one way or another. The first step in the path of treatment is education and confidence of patients that might also be the most important step. Fiber diet, probiotic, anti-cholinergic and anti antispasmodics, laxatives, anti-diarrhea, the drugs affecting serotonin receptors, antidepressants and anti-anxiety, the chloride channel activator and non-drug methods such as cognitive-behavior therapy, hypnotherapy, acupuncture and herbal medicine each of which has been tested on irritable bowel syndrome and efficacy of each one has been indicated in one way or another. This paper tried to outline new treatments available in addition to categorization and discussion of various treatments for irritable bowel syndrome.Keywords: Irritable Bowel Syndrome; Probiotics; Parasmpatholytics; Laxatives.

Comparison of geographic distributions of Irritable Bowel Syndrome with Inflammatory Bowel Disease fail to support common evolutionary roots: Irritable Bowel Syndrome and Inflammatory Bowel Diseases are not related by evolution.

Irritable Bowel Syndrome (IBS) shares overlapping symptoms and some features of pathogenesis with Inflammatory Bowel Diseases (IBD: Crohn's disease [CD], and Ulcerative Colitis [UC]). Geographic markers such as latitude/sunshine and more recently lactase population distributions are found to be correlated with IBD. As a result of clinical and pathogenic similarities between the 2 conditions, some authorities questioned whether a connection exists between them. We compare IBS directly with IBD, and indirectly with geographic markers associated with IBD, in order to evaluate possible evolutionary links between IBS and IBD. Similar correlations may link IBS as a precursor to IBD and possibly other conditions which are geographically connected with IBD. Data from four systematic reviews on IBD incidence and prevalence, IBS prevalence, and lactase distributions were included. Pearson's correlations were used for comparisons, with IBD values log-transformed because of skewed distribution. The articles provided 18-28 complete set of national data. Direct comparison between IBS and IBD showed no significant correlations (r = -0.14, r = -0.06 for CD and UC prevalence, r = -0.10 for CD incidence). Indirect comparisons also failed to show correlations of IBS with lactase distributions (r = -0.17), sunshine (r = -0.2) or latitude (r = 0.097); however, there was significant correlation between lactase distributions and CD incidence (r = -0.84), prevalence (r = -0.55) and UC prevalence (r = -0.59). Both sunshine (r= -0.53) and latitude (r = 0.58) are also significantly related to CD incidence. It is concluded that IBS and IBD do not follow similar global geographic patterns. This suggests a lack of an evolutionary genetic background coincident with emergence of lactase persistence. As well, vitamin D has no obvious impact on development of IBS. Similarities with IBD may result from sub groups (not yet identified) within the current Rome

Bowel angioedema is an acute adverse reaction to iodinated contrast media (CM) that involves the gastrointestinal tract. We aimed to investigate the incidence and predisposing factors of iodinated CM-associated bowel angioedema during computed tomography (CT) examinations. This study was approved by our institutional review board, and informed consent was waived due to its retrospective design. From July 2013 to July 2015, adult patients with a history of adverse reactions to iodinated CM during CT (group A, n = 427) and patients without adverse reactions matched for age and sex with the propensity-score matching method (group B, n = 427) were studied. Contrast media-associated bowel angioedema was determined when bowel wall thickness increased after contrast enhancement compared with the precontrast scan. Potential predisposing factors including patient demographics, symptoms and time of adverse reactions, and CM-related factors were compared between patients with and without angioedema in group A. In addition, the incidence of bowel angioedema was compared between groups A and B. The incidence of CM-associated bowel angioedema in group A was 3.3% (14/427) in the per-patient analysis and 2.6% (15/578) in the per-examination analysis. The CM-associated bowel angioedema involved the distal duodenum and/or proximal jejunum and showed long-segmental circumferential bowel wall thickening on CT. None of the studied predisposing factors was different between patients with and without bowel angioedema (P > 0.05). The incidence of CM-associated bowel angioedema in group B was 1.9% (8/427) and 1.7% (8/458) for per-patient and per-examination analyses, respectively, and these rates were not significantly different between groups A and B (P = 0.346 and P = 0.370, respectively). The incidence of CM-associated bowel angioedema during CT was 1.7% to 3.3%, and none of the studied predisposing factors was associated with bowel angioedema.

Injury to the small bowel is one of the tragic complications of radiotherapy. We performed a retrospective analysis of patients operated upon for stenosis, perforation, fistulization, and chronic blood loss of the small bowel after radiotherapy for multiple malignant diseases. In the period 1970 to 1982 in the Department of General Surgery of the St. Radboud University Hospital, Nijmegen, and the Department of Surgical Oncology of the State University, Groningen, 27 patients were treated surgically. Twenty patients presented with obstruction. In 17 patients a side-to-side ileotransversostomy was performed; in three the injured bowel was resected. Of the five patients with fistulization, three underwent a bypass procedure; in two cases the affected bowel was resected. In one patient with perforation, a resection was performed, as in a patient with chronic blood loss. Two of the 20 patients (10 per cent) in whom the diseased bowel was bypassed died postoperatively. Of the seven patients whose affected bowel was resected four (57 per cent) died of intra-abdominal sepsis. Management of the patient with chronic radiation enteritis is discussed. We conclude, on the basis of our experience, that in patients with obstruction and fistulization, a bypass procedure of the affected bowel is a safe method of treatment. In case of resection, the anastomosis should be performed during a second operation.

Small bowel obstruction is a clinical condition commonly caused by postoperative adhesion, volvulus, intussusceptions, and hernia. Small bowel obstruction due to bezoars is clinically uncommon, accounting for approximately 2-4% of all obstructions. Computed tomography (CT) is a useful method in diagnosing the cause of small bowel obstruction. However, small bowel obstruction caused by bezoars may not be detected by an abdominal CT examination. Herein, we report a rare case of small bowel obstruction by Aloe vera bezoars, which were undetected by an abdominal CT. Phytobezoars should be included in the differential diagnosis of small bowel obstruction in patients with predisposing factors, such as excessive consumption of high-fiber food and diabetes.

Pharmacological treatment of bowel obstruction in cancer patients.

LENUS (Irish Health Repository)

O'Connor, Brenda

2012-02-01

INTRODUCTION: Malignant bowel obstruction (MBO) is a common complication of advanced cancer, occurring most frequently in gynaecological and colorectal cancer. Its management remains complex and variable. This is in part due to the lack of evidence-based guidelines for the clinicians involved. Although surgery should be considered the primary treatment, this may not be feasible in patients with a poor performance status or advanced disease. Advances have been made in the medical management of MBO which can lead to a considerable improvement in symptom management and overall quality of life. AREAS COVERED: This review emphasizes the importance of a prompt diagnosis of MBO with early introduction of pharmacological agents to optimize symptom control. The authors summarize the treatment options available for bowel obstruction in those patients for whom surgical intervention is not a feasible option. The authors also explore the complexities involved in the introduction of parenteral hydration and total parenteral nutrition in this group of patients. EXPERT OPINION: It is not always easy to distinguish reversible from irreversible bowel obstruction. Early and aggressive management with the introduction of pharmacological agents including corticosteroids, octreotide and anti-cholinergic agents have the potential to maintain bowel patency, and allow for more rapid recovery of bowel transit. A combination of analgesics, anti-emetics and anti-cholinergics with or without anti-secretory agents can successfully improve symptom control in patients with irreversible bowel obstruction.

To evaluate the CT findings of small bowel metastases from primary lung cancer. Of the 1468 patients with primary lung cancer between 1990 and 2000, 13 patients who had metastasis to the small intestine were collected. Of these 13 patients, nine who underwent CT scan were included for analysis. The pathologic diagnoses of primary lung cancer in these nine patients were squamous cell carcinoma in six, adenocarcinoma in two, and large cell carcinoma in one. CT scans were analyzed with regard to the site and patterns (intraluminal mass/bowel wall thickening/bowel implants) of metastatic masses, and the presence or absence of complication such as intussusception, obstruction, or perforation of the small bowel. The medical records of the patients were also reviewed retrospectively for evaluation of presenting abdominal symptom and time interval of metastases from initial diagnosis of lung cancer. Metastatic lesions were distributed throughout the small intestine: the duodenum in five, the jejunum in four, the ileum in six, and both jejunum and ileum in one patient. The size of metastatic masses of small bowel ranged from 1.3 cm to 5.0 cm (mean size, 2.6 cm) On CT, the small bowel was involved with intraluminal masses (mean size, 3.4 cm) in eight patients, diffuse wall thickening (mean thickness, 1.6 cm) in five, and bowel implants (mean size, 2.2 cm) in two. Complications occurred in seven patients, including intussusceptions without obstruction in two patients and with obstruction in two, obstruction without intussusceptions in two, and bowel perforation in one. Of 9 patients, 6 had at least one symptom referable to the small bowel including abdominal pain in 4, anemia in 3, vomiting in 1, and jaundice in 1. Lung cancer and small bowel lesions were detected simultaneously in four patients and the time interval of metastases from initial diagnosis of lung cancer ranged from 10 days to 30 months (median interval, 54 days) in patients. CT helps in defining the extent and

Acute bowel ischemia represents one of the most dramatic abdominal emergencies and, despite the fact it is more and more frequently observed in clinical practice, its mortality rate remains very high. In recent years Computed Tomography (CT) has proved to be a valid diagnostic tool in the evaluation of patients with acute abdominal syndrome and in the visualization of early signs of bowel ischemia. This paper reviews the aetiological and pathophysiological aspects as well as a broad spectrum of CT findings of this clinical condition

Bowel-associated dermatosis-arthritis syndrome (BADAS) is characterized by combined pustular skin eruption and arthralgia. It may be associated with inflammatory bowel disease or bowel bypass surgery. We report a case of BADAS in a patient with ulcerative colitis. A 39-year-old woman was being treated for a severe flare-up of ulcerative colitis present over the preceding 2 months and treated with prednisone, azathioprine and cyclosporine. She was also presenting a cutaneous eruption and arthralgia that had begun three days earlier. Dermatological examination revealed profuse vesicular and pustular lesions. Biopsy specimens showed mature neutrophilic infiltrate within the dermis. A diagnosis of BADAS was made and the same treatment was maintained. Systemic symptoms were resolved but the vesicular lesions were superseded by hypertrophic scars. Bowel-associated dermatosis-arthritis syndrome consists of a vesiculopustular eruption associated with arthralgia and/or arthritis and fever, as was the case in our patient. The histological picture is characterized by abundant neutrophilic infiltrate in the superficial dermis. The clinical and histological features and the course of BADAS allow this entity to be classified within the spectrum of neutrophilic dermatoses. Treatment chiefly involves systemic corticosteroids.

Seventy-seven patients, presenting with radiation small bowel injuries at the University of Texas M. D. Anderson Hospital and Tumor Institute at Houston between 1962 and 1978, were analyzed retrospectively. The patients were divided into two categories: bowel bypass without resection, and resection of irradiated bowel. Each group was then analyzed for its short- and long-term complications. Ileocolectomy with end-to-end anastomosis was the surgical procedure of choice in those people undergoing resection. There was no difference in short-term complications noted between the two groups. The long-term complications of fistula formation and continued small bowel necrosis could be prevented by resection, as a primary procedure. The surgical details of ileocolectomy with end-to-end anastomosis are presented, along with an analysis of the complications encountered in both groups.

Shen, Xiao-Fei; Guan, Wen-Xian; Cao, Ke; Wang, Hao; Du, Jun-Feng

2015-09-28

Small bowel volvulus, which is torsion of the small bowel and its mesentery, is a medical emergency, and is categorized as primary or secondary type. Primary type often occurs without any apparent intrinsic anatomical anomalies, while the secondary type is common clinically and could be caused by numerous factors including postoperative adhesions, intestinal diverticulum, and/or tumors. Here, we report a rare case of a 60-year-old man diagnosed with small bowel volvulus using multidetector computed tomography (MDCT) angiography. Further discovery by laparotomy showed one jejunal diverticulum, longer corresponding mesentery with a narrower insertion, and a lack of mesenteric fat. This case report includes several etiological factors of small bowel volvulus, and we discuss the possible cause of small bowel volvulus in this patient. We also highlight the importance of MDCT angiography in the diagnosis of volvulus and share our experience in treating this disease.

The normal small bowel fold is easily seen on conventional studies of the small intestine, but visualization of the small bowel villus is just at the resolution of current roentgenographic technique. When the villi are enlarged, they can be seen radiographically as an irregularity or micronodularity of the small bowel fold. The anatomy of the fold and the pathophysiology of diseases producing fold nodularity (tumor, inflammatory disease, NLH, mastocytosis) and micronodularity (lymphangiectasia, Waldenstrom macroglobulinemia, Whipple disease) are presented, with an emphasis on radiologic-pathologic correlation. The radiologist should suggest certain diseases or conditions based on the roentgenographic characteristics of the closely analyzed small bowel fold

Objective: Evaluate the use of MDCT with 3D CT angiography (CTA) and CT portal venography (CTPV) reconstruction for the diagnosis of small bowel volvulus (SBV). Methods: Multiphasic MDCT findings in nine patients (seven males and two females, age range 2-70) with surgically proven SBV were retrospectively reviewed. Non-contrast and double phase contrast enhanced MDCT including 3D CTA and CTPV reconstruction were performed in all the patients. Two experienced abdominal radiologists evaluated the images and defined the location, direction and degree of SBV. Results: On axial MDCT images, all cases show segmental or global dilatation of small intestine. Other findings include circumferential bowel wall thickening in eight cases, halo appearance and hyperemia in seven cases, whirl sign in six cases, beak-like appearance in six cases, closed loops in six cases and ascites in one case. CTA/CTPV showed abnormal courses involving main trunks of superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in seven cases, with or without distortion of their tributaries. Normal course of SMA but abnormal course of SMV was seen in the other two cases. Of all the nine cases, whirl sign was seen in six cases and barber's pole sign in five cases. Dilated SMV was observed in eight cases and abrupt termination of SMA was found in one case. Compared with surgical findings, the location, direction and degree of SBV were correctly estimated in all cases based on CTA/CTPV. Conclusion: Multiphasic MDCT with CTA/CTPV reconstruction can play an important role in the diagnosis of SBV. The location, direction and degree of SBV can all be defined preoperatively using this method.

2016-01-01

The incidence of inflammatory bowel diseases (IBD) - Crohn’s disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

Full Text Available INTRODUCTION: Invasive and non-invasive tests can be used to evaluate the activity of inflammatory bowel diseases. OBJECTIVE: The aim of the present study was to investigate the role of fecal calprotectin in evaluating inflammatory bowel disease activity and the correlation of fecal calprotectin with the erythrocyte sedimentation rate and C reactive protein values in inflammatory bowel disease. METHOD: Sixty-five patients affected with inflammatory bowel disease were enrolled. Twenty outpatients diagnosed with inflammatory bowel disease comprised the control group. RESULTS: In the present study, all patients in the control group had an fecal calprotectin value lower than the cut-off point (50 mg/kg. CONCLUSION: In conclusion, fecal calprotectin was found to be strongly associated with colorectal inflammation indicating organic disease. Fecal calprotectin is a simple and non-invasive method for assessing excretion of macrophages into the gut lumen. Fecal calprotectin values can be used to evaluate the response to treatment, to screen asymptomatic patients, and to predict inflammatory bowel disease relapses.

The effects of the volume of irradiated small bowel on late small-bowel tolerance was studied, taking into account the equivalent total dose ant type of pre-irradiation surgical procedure. A method was developed to estimate small-bowel volumes in the high-bowel volumes were measured for three-field and AP-PA pelvic treatments (165 cm 3 and 400 cm 3 , respectively), extended AP-PA treatment of para-aortic and iliac nodes (1000 cm 3 ). In a retrospective study of 111 patientst irradiated after surgery for rectal or recto-sigmoid cancer to a dose of 45-50 Gy in 5 weeks, extended AP-PA pelvic treatment (n = 27) resulted in a high incidence of severe small-bowel complications (37%), whereas for limited (three-field) pelvic treatment (n = 84) the complication rate was 6%. These complication data together with data from the literature on postoperative radiation-related small-bowel complications were analysed using the maximum likelihood method to fit the data to the logistic form of the dose-response relation, taking the volume effect into account by a power law. The analysis indicated that the incidence of radiation-related small-bowel compllications was higher after rectal surgery than after other types of surgery, which might be explained by the development of more adhesions. For both types of surgery a volume exponent of the power-law of 0.26 ± 0.05 was established. This means that if the small-bowel volume is increased by a factor of 2, the total dose has to be reduced by 17% for the same incidence of small-bowel complications.

AIM: To investigate the effectiveness of low-volume plus ascorbic acid [polyethylene glycol plus ascorbic acid (PEG + Asc)] and high-volume plus simethicone [polyethylene glycol plus simethicone (PEG + Sim)] bowel preparations. METHODS: A total of one hundred and forty-four outpatients (76 males), aged from 20 to 84 years (median age 59.5 years), who attended our Department, were divided into two groups, age and sex matched, and underwent colonoscopy. Two questionnaires, one for patients reporting acceptability and the other for endoscopists evaluating bowel cleansing effectiveness according to validated scales, were completed. Indications, timing of examination and endoscopical findings were recorded. Biopsy forceps were used as a measuring tool in order to determine polyp endoscopic size estimation. Difficulty in completing the preparation was rated in a 5-point Likert scale (1 = easy to 5 = unable). Adverse experiences (fullness, cramps, nausea, vomiting, abdominal pain, headache and insomnia), number of evacuations and types of activities performed during preparation (walking or resting in bed) were also investigated. RESULTS: Seventy-two patients were selected for each group. The two groups were age and sex matched as well as being comparable in terms of medical history and drug therapies taken. Fourteen patients dropped out from the trial because they did not complete the preparation procedure. Ratings of global bowel cleansing examinations were considered to be adequate in 91% of PEG + Asc and 88% of PEG + Sim patients. Residual Stool Score indicated similar levels of amount and consistency of residual stool; there was a significant difference in the percentage of bowel wall visualization in favour of PEG + Sim patients. In the PEG + Sim group, 12 adenomas ≤ 10 mm diameter (5/left colon + 7/right colon) vs 9 (8/left colon + 1/right colon) in the PEG + Asc group were diagnosed. Visualization of small lesions seems to be one of the primary advantages of the

Inflammatory bowel disease and irritable bowel syndrome: similarities and differences.

Inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) are classically viewed as dichotomous conditions. The former is perceived as a typical organic disease, and the latter is regarded as a disorder of gut function driven by mood. Recent research identified some shared contributing factors, which will be discussed here. Mounting evidence shows the importance in both IBD and IBS of genetic, microbiological, epithelial, and immunological factors. In some instances, these factors overlap in the two conditions as shown by: involvement of brain-gut axis dysfunction in IBD, implication of TNFSF gene in Crohn's disease and IBS, evidence of abnormal microbiota and its impact on host functions, identification of low-grade inflammation in subsets of IBS patients, and development of IBS symptoms in patients with IBD in remission. IBD and IBS remain separate conditions although there are some overlapping mechanisms. Both research and clinical management would benefit from considering a functional approach for certain manifestations of IBD and accepting an organic view in subsets of IBS patients.

The ideal preparation regimen for pediatric colonoscopy remains elusive, and available preparations continue to represent a challenge for children. The aim of this study was to compare the efficacy, safety, tolerability, and acceptance of 4 methods of bowel cleansing before colonoscopy in children. This randomized, investigator-blinded, noninferiority trial enrolled all children aged 2 to 18 years undergoing elective colonoscopy in a referral center for pediatric gastroenterology. Patients were randomly assigned to receive polyethylene glycol (PEG) 4000 with simethicon (PEG-ELS group) or PEG-4000 with citrates and simethicone plus bisacodyl (PEG-CS+Bisacodyl group), or PEG 3350 with ascorbic acid (PEG-Asc group), or sodium picosulfate plus magnesium oxide and citric acid (NaPico+MgCit group). Bowel cleansing was evaluated according to the Boston Bowel Preparation Scale. The primary end point was overall colon cleansing. Tolerability, acceptability, and compliance were also evaluated. Two hundred ninety-nine patients were randomly allocated to the 4 groups. In the per-protocol analysis, PEG-CS+Bisacodyl, PEG-Asc, and NaPico+MgCit were noninferior to PEG-ELS in bowel-cleansing efficacy of both the whole colon (P = .910) and colonic segments. No serious adverse events occurred in any group. Rates of tolerability, acceptability, and compliance were significantly higher in the NaPico+MgCit group. Low-volume PEG preparations (PEG-CS+Bisacodyl, PEG-Asc) and NaPico+MgCit are noninferior to PEG-ELS in children, representing an attractive alternative to high-volume regimens in clinical practice. Because of the higher tolerability and acceptability profile, NaPico+MgCit would appear as the most suitable regimen for bowel preparation in children.

Svensson, M.H.; Hellstroem, M.; Svensson, E.

2002-01-01

Purpose: To evaluate the quality of bowel wall visualisation at CT colonography and the impact of examination in the supine and prone positions. Material and Methods: After bowel preparation, 111 patients underwent CT colonography. Air distension, degree of fluid redistribution with change in body position (supine and prone), influence of residual stool on bowel wall assessability, and quality of overall colon visualisation were evaluated using scales. Results: Thirty of 110 patients (27%) had complete overall visualisation of the colon wall and 52 (47%) had subtotal visualisation of a limited part of the colon. The entire colon was more often air-filled in the prone position (46%) than in the supine position (18%). Joint review of supine and prone data showed that for all colon segments, except the sigmoid (86%), 95% of the patients had complete air filling. All patients had residual fluid. In 75% to 99%, depending on segment, fluid did not interfere with the bowel wall visualisation in the combined evaluation of supine and prone data sets. Thirty-one patients had residual stool with potential negative influence on polyp detection. Conclusions: The colon wall was completely, or almost completely, visualised in 75% of the patients, and examination in the supine and prone positions was necessary for complete visualisation

Bowel disease after radiotherapy

The clinical presentation, operative findings and outcome in 40 patients who required surgery for bowel disease after radiotherapy are presented. The type of presentation varied according to the time after radiotherapy. In the first month, many patients had a proctitis but none required surgery. Five patients were operated on within one month, 2 for radiation-induced acute ileitis and 3 for exacerbations of pre-existing disease (diverticular disease 2, ulcerative colitis 1). The commonest time of presentation was between 3 and 18 months after radiotherapy, when 20 patients needed surgery for bowel disease caused by radiation-induced local ischaemia. Twelve of these patients had chronic perforation, 6 had severe rectal bleeding and 2 had painful anorectal ulceration. Fifteen patients presented between 2 and 24 years after radiotherapy, usually with incomplete intestinal obstruction due to a fibrous stricture, but 2 patients had rectal carcinoma. Wide resection of the involved bowel was the principal method of treatment but any anastomosis was protected by a proximal defunctioning stoma. There was no operative mortality but 10 patients have died subsequently. The danger of dismissing these patients as having incurable malignancy is stressed because, although the condition is infrequent, it is usually amenable to adequate surgery.

To explore the associations between latitude and solar radiation with inflammatory bowel disease admission rates in Chile, the country with the largest variation in solar radiation in the world. This is an ecological study, which included data on all hospital-admitted population for inflammatory bowel disease between 2001 and 2012, according to different latitudes and solar radiation exposures in Chile. The data were acquired from the national hospital discharge database from the Department of Health Statistics and Information of the Chilean Ministry of Health. Between 2001 and 2012 there were 12,869 admissions due to inflammatory bowel disease (69% ulcerative colitis, 31% Crohn's disease). Median age was 36 years (IQR: 25-51); 57% were female. The national inflammatory bowel disease admission rate was 6.52 (95% CI: 6.40-6.63) per 100,000 inhabitants with increasing rates over the 12-year period. In terms of latitude, the highest admission rates for pediatric ulcerative colitis and Crohn's disease, as well as adult ulcerative colitis, were observed in the southernmost region with lowest annual solar radiation. Linear regression analysis showed that regional solar radiation was inversely associated with inflammatory bowel disease admissions in Chile (β: -.44, p = .03). Regional solar radiation was inversely associated with inflammatory bowel disease admission rates in Chile; inflammatory bowel disease admissions were highest in the southernmost region with lowest solar radiation. Our results support the potential role of vitamin D deficiency on inflammatory bowel disease flares.

Kim, Won Dong

1999-01-01

This study evaluated early bowel complications in cervix cancer patients, following external radiotherapy (ERT) and high dose rate intracavitary radiation (HDR ICR). Factors affecting the risk of developing early bowel complications and its incidence are analyzed and discussed. The study is the retrospective review of 66 patients who received radiotherapy at Chungbuk National University Hospital from April 1994 to December 1998. The patients underwent 41.4 or 50.4 Gy ERT according to FIGO stage and tumor size, then A point dose was boosted to 71.4 or 74.4 Gy using a remotely controlled after loading Buchler HDR ICR. The EORTC/RTOG morbidity criteria were used to grade early bowel complications, which are valid from day 1, the commencement of therapy, through day 90. The actuarial incidence, severity of complications were investigated and clinical pretreatment factors relevant to complications were found through univariate (Wilcoxon) and multivariate (Cox proportional hazard model) analysis. Of the 66 patients, 30 patients (46%) developed early bowel complications; 25 patients (38%) with grade 1 or 2, 4 patients (6%) with grade 3 and 1 patient (2%) with grade 4. The complications usually began to occur 3 weeks after the commencement of radiotherapy. The actuarial incidence of early bowel complications was 41% at 10 weeks. The early bowel complications were associated significantly with an old age and a history of previous abdomino-pelvic surgery. All three patients who had a protracted overall treatment time (about 2 weeks) due to severe bowel complication, suffered from pelvic recurrences. Forty six percent of patients experienced early bowel complications, most of which were grade 1 or 2 and relieved spontaneously or by medication. The patients with an old age or a previous surgery have a high probability of early complications and they may be less compliant with planned radiotherapy. So more careful precaution is necessary for these patients

Protocol for a randomized controlled study of Iyengar yoga for youth with irritable bowel syndrome

2011-01-01

Full Text Available Abstract Introduction Irritable bowel syndrome affects as many as 14% of high school-aged students. Symptoms include discomfort in the abdomen, along with diarrhea and/or constipation and other gastroenterological symptoms that can significantly impact quality of life and daily functioning. Emotional stress appears to exacerbate irritable bowel syndrome symptoms suggesting that mind-body interventions reducing arousal may prove beneficial. For many sufferers, symptoms can be traced to childhood and adolescence, making the early manifestation of irritable bowel syndrome important to understand. The current study will focus on young people aged 14-26 years with irritable bowel syndrome. The study will test the potential benefits of Iyengar yoga on clinical symptoms, psychospiritual functioning and visceral sensitivity. Yoga is thought to bring physical, psychological and spiritual benefits to practitioners and has been associated with reduced stress and pain. Through its focus on restoration and use of props, Iyengar yoga is especially designed to decrease arousal and promote psychospiritual resources in physically compromised individuals. An extensive and standardized teacher-training program support Iyengar yoga's reliability and safety. It is hypothesized that yoga will be feasible with less than 20% attrition; and the yoga group will demonstrate significantly improved outcomes compared to controls, with physiological and psychospiritual mechanisms contributing to improvements. Methods/Design Sixty irritable bowel syndrome patients aged 14-26 will be randomly assigned to a standardized 6-week twice weekly Iyengar yoga group-based program or a wait-list usual care control group. The groups will be compared on the primary clinical outcomes of irritable bowel syndrome symptoms, quality of life and global improvement at post-treatment and 2-month follow-up. Secondary outcomes will include visceral pain sensitivity assessed with a standardized

ACG Clinical Guideline: Diagnosis and Management of Small Bowel Bleeding.

Science.gov (United States)

Gerson, Lauren B; Fidler, Jeff L; Cave, David R; Leighton, Jonathan A

2015-09-01

Bleeding from the small intestine remains a relatively uncommon event, accounting for ~5-10% of all patients presenting with gastrointestinal (GI) bleeding. Given advances in small bowel imaging with video capsule endoscopy (VCE), deep enteroscopy, and radiographic imaging, the cause of bleeding in the small bowel can now be identified in most patients. The term small bowel bleeding is therefore proposed as a replacement for the previous classification of obscure GI bleeding (OGIB). We recommend that the term OGIB should be reserved for patients in whom a source of bleeding cannot be identified anywhere in the GI tract. A source of small bowel bleeding should be considered in patients with GI bleeding after performance of a normal upper and lower endoscopic examination. Second-look examinations using upper endoscopy, push enteroscopy, and/or colonoscopy can be performed if indicated before small bowel evaluation. VCE should be considered a first-line procedure for small bowel investigation. Any method of deep enteroscopy can be used when endoscopic evaluation and therapy are required. VCE should be performed before deep enteroscopy if there is no contraindication. Computed tomographic enterography should be performed in patients with suspected obstruction before VCE or after negative VCE examinations. When there is acute overt hemorrhage in the unstable patient, angiography should be performed emergently. In patients with occult hemorrhage or stable patients with active overt bleeding, multiphasic computed tomography should be performed after VCE or CTE to identify the source of bleeding and to guide further management. If a source of bleeding is identified in the small bowel that is associated with significant ongoing anemia and/or active bleeding, the patient should be managed with endoscopic therapy. Conservative management is recommended for patients without a source found after small bowel investigation, whereas repeat diagnostic investigations are recommended

A new method employing 99mTc-labeled pellets for determination of the gastric emptying rate and small bowel transit time is described. The participants were six normal subjects and 16 patients with irritable bowel syndrome (eight with diarrhea and eight with obstipation as the primary complaint). The gastric emptying rate was the same in the three groups. The patients in the obstipation group had a significantly longer small bowel transit time than the normals (P less than 0.02) and the patients in the diarrhea group (P less than 0.01). There was no demonstrable difference between the small bowel transit time in the normals and in the patients in the diarrhea group.

The patients in the obstipation group had a significantly longer small bowel transit time than the normals (P less than 0.02) and the patients in the diarrhea group (P less than 0.01). There was no demonstrable difference between the small bowel transit time in the normals and in the patients in the diarrhea group

Full Text Available Treatment of functional bowel disorders of irritable bowel-type (IBS in children remains a difficult task because of a lack of drugs with low adverse event profile. We here report the results of a treatment study in 203 children (66 boys and 137 girls age 4 to 18 years (mean: 10.5±4.5 years with typical IBS symptoms with abdominal pain and either predominant diarrhea (n=50, constipation (n=56, alternating stool frequency (n=28 or unspecific pain (n=69. The average duration of symptoms prior to therapy was 175 days. Most (95% patients up to age 11 were treated with a daily dose of 10 drops of Symbioflor 2 (SF2 (SymbioPharm, Herborn (cells and autolysate of 1.5–4.5x107 CFU of bacteria of Escherichia coli type, in the elder children 77% received this dosage, while the remaining received a higher dose up to 30 drops/day. Treatment lasted 43 days on average. Results: All patients tolerated the treatment well and without adverse events. The key IBS symptoms (abdominal pain, stool frequency as well as the other symptoms (bloating, mucous and blood in stool, need for straining at stools, urge to defecate improved significantly during treatment. Global assessment of therapy by parents and doctors was altogether positive. In summary these data confirm efficacy and tolerability of this probiotic compound in children and adolescents and supplement published data of probiotic IBS therapy in adults.

Proctalgia fugax in patients with the irritable bowel, peptic ulcer, or inflammatory bowel disease.

Thompson, W G

1984-06-01

One hundred forty-eight patients with gastrointestinal disease, 50 patients with the irritable bowel syndrome (IBS) and 49 each with peptic ulcer and inflammatory bowel disease, were interviewed to determine if they had proctalgia fugax (PF) and if the symptom was associated with the IBS. One-third of the patients had PF. It occurred in 51% of females and 12% of males (p less than 0.001). When corrected for sex, PF was no more prevalent in IBS than in peptic ulcer or inflammatory bowel disease. Only two of six previously described IBS symptoms were more prevalent in the PF patients. Attacks occurred in the day in 94%, and one-third of sufferers related them to defecation. The pain was localized in the anus in 90%, occurred less than five times a year in 51%, and lasted less than 1 min in 57%. In most, activity was not interrupted by this pain and only 20% had ever reported it to a physician. PF is very common among patients with abdominal symptoms, but is not related to the IBS. Since it is infrequent, benign, and transient, PF is usually not mentioned to the physician.

Aim: To analyse the technical success and reporting sensitivity of radiographer performed small bowel enteroclysis (SBE) undertaken by a specialist radiographer according to a standard technique [Nolan DJ, Cadman PJ. The small bowel enema made easy. Clinical Radiology 1987;38(3):295-301]. Methods: Patients (1413) had 1646 SBE in 10 years from May 1992 to April 2002. The original request card and the separate radiographer and consultant radiologist reports were reviewed. Where the radiology reports were discordant or inconclusive, the clinical notes were also reviewed. Results: Patients (1022) X-ray films were available. Nine hundred and forty-three (93.3%) SBEs had been successfully completed. Radiographer and consultant radiologist reporting had a 99.3% concordance. There was a 98.4% sensitivity for Crohn's disease (181 of 184 cases where Crohn's disease was the clinical final diagnosis). Overall reporting sensitivity was 93.7% although correct 'probably normal and abnormal' reporting bias suggests a sensitivity of 96.9%. Sixty of 943 (6.4%) reports were inconclusive. Of 1022 patients, 68 (6.6%) of small bowel intubations were not achieved, or else consent was withdrawn at the time of the procedure. Conclusion: Specialist radiographers can perform small bowel enteroclysis with a reporting sensitivity equal to that of a consultant radiologist. Radiographers accustomed to providing an SBE service become skilled at passing fine bore feeding tubes into the small bowel and can provide this service also

Small-bowel carcinoid with no liver metastases.

2009-01-01

Carcinoid is a slowly-growing tumor from the group of neuroendocrine or APUD tumors. Characteristic of these tumors is the production of biogene amins & polypeptide hormones. 90% of all carcinoids are located in the GI system. A female patient, 68 years old, comes for a visit with signs of diffuse abdominal pain, diarrhea, irregular bowel movements, weakness, dyspnea and pretibial edemas. The gastroenterologist gives her only symptomatic therapy at first, and starts the examinations after her hospitalization (initial dg: Enterocolitis). One month later she visits again with the same complains. CT scan result shows steatosis hepatica and lots of liquids in the small bowel and colon. She underwent operation--resection of 20 cm of the small bowel with tumor masses and part-time ileostoma. The biopsy of the resected segment of the bowel shows multiple carcinoids. Our patient had no flushing of the skin and therefore couldn't be suspected clinically for this diagnosis. The intestinal carcinoid does not usually produce the carcionid syndrome unless hepatic metastases have occurred. The infiltration of the mesentery provokes an intense fibrotic reaction resulting in kinking of the bowel segments, which causes intestinal obstruction as it happened in this patient. As long as in our clinic we don't have this technique, it is much harder to make an early diagnosis. Fortunately our patient was diagnosed before liver metastases occurred, and therefore her treatment was successful.

The objective of this article is to review the pathophysiology of acute small bowel diseases, and to correlate the mechanisms of disease with computed tomography (CT) findings. Disease entities will be classified into the following: immune mediated and infectious causes, vascular causes, mechanical causes, trauma, and others. Having an understanding of acute small bowel pathophysiology is a useful teaching tool, and can lead to imaging clues to the most likely diagnosis of acute small bowel disorders.

Large Intraluminal Ileal Hematoma Presenting as Small Bowel Obstruction in a Child

International Nuclear Information System (INIS)

Lim, Yun Jung; Nam, So Hyun; Kim, Seon Jeong

2015-01-01

Intraluminal small bowel hematoma has been rarely reported in children, as a rare cause of small bowel obstruction. We present a case of an intraluminal ileal hematoma presenting as small bowel obstruction in a child. Computed Tomography (CT) indicated a large intraluminal hyperdense lesion in the distal ileum as the cause of small bowel obstruction. Abdominal ultrasonography (US) showed an echogenic mass-like lesion with multiple septa in the distal ileum. Small bowel obstruction due to a complicated cystic mass was provisionally diagnosed. Histopathologic examination of the resected mass suggested a submucosal ileal hematoma. Although intraluminal small bowel hematoma is rare in children, it can present as an intraluminal cystic mass and should be considered as a rare cause of small bowel obstruction. The US and CT findings of submucosal ileal hematoma could be useful for the diagnosis of such cases in the future

The aim of this study was to evaluate the effect of using different floor types to accommodate growing and finishing beef cattle on their performance, cleanliness, carcass characteristics and meat quality. In total, 80 dairy origin young bulls (mean initial live weight 224 kg (SD=28.4 kg)) were divided into 20 blocks with four animals each according to live weight. The total duration of the experimental period was 204 days. The first 101 days was defined as the growing period, with the remainder of the study defined as the finishing period. Cattle were randomly assigned within blocks to one of four floor type treatments, which included fully slatted flooring throughout the entire experimental period (CS); fully slatted flooring covered with rubber strips throughout the entire experimental period (RS); fully slatted flooring during the growing period and moved to a solid floor covered with straw bedding during the finishing period (CS-S) and fully slatted flooring during the growing period and moved to fully slatted flooring covered with rubber strips during the finishing period (CS-RS). Bulls were offered ad libitum grass silage supplemented with concentrates during the growing period. During the finishing period, bulls were offered concentrates supplemented with chopped barley straw. There was no significant effect of floor type on total dry matter intake (DMI), feed conversion ratio, daily live weight gain or back fat depth during the growing and finishing periods. Compared with bulls accommodated on CS, RS and CS-RS, bulls accommodated on CS-S had a significantly lower straw DMI (Pcarcass characteristics or meat quality. However, bulls accommodated on CS-S had a tendency for less channel, cod and kidney fat (P=0.084) compared with those accommodated on CS, RS and CS-RS. Overall, floor type had no effect on the performance, cleanliness, carcass characteristics or meat quality of growing or finishing beef cattle.

Irritable bowel syndrome is the most frequent functional disorder of the digestive system. Patients with irritable bowel syndrome have motor disorders not only in the colon, but also in other parts of the digestive tract such as the oesophagus and small intestine; however, it is not known whether the stomach is also involved. We used a radiolabelled mixed solid-liquid meal (technetium-99m for the solid component, indium-111 for the liquid component) to study gastric emptying of solids (GES), liquids (GEL) and indigestible solids (GER) in 50 patients diagnosed as having irritable bowel syndrome (30 with predominant constipation and 20 with predominant diarrhoea). GER was measured by counting the number of indigestible solids remaining in the stomach 4 h after they were swallowed. In patients with irritable bowel syndrome, GES and GEL were slower than in control subjects (P<0.05). GER was normal in all patients except for two women. Thirty-two patients (64%) showed delayed GES, 29 (58%) delayed GEL, and 2 (4%) delayed GER. Among patients with irritable bowel syndrome, GES was slower in those with predominant constipation than in those with predominant diarrhoea (P<0.05); GEL and GER were similar in both groups. Gastroparesis was found in a large proportion of patients with irritable bowel syndrome, suggesting the presence of a more generalised motor disorder of the gut. (orig.)

Getting ready for a colonoscopy is difficult and involves many steps. Information given to patients is very important for adherence to treatment. We created a novel smart phone application (SPA) aimed to increase bowel preparation quality and patient satisfaction. We carried out a prospective, endoscopist-blinded, randomized, controlled trial. We enrolled 260 outpatient (58% female, age range 21-75 years) owners of a smartphone. Patients were allocated to two different protocols: instructions provided by SPA (SPA group; n = 108) or written instructions with visual aids (control group; n = 152). All procedures were carried out in the afternoon and patients received the same purgative regimen (2 L polyethylene glycol (PEG) solution plus ascorbic acid), in a full-dose same-day regimen. The study was designed to detect an improvement in quality of bowel preparation using the Harefield Cleansing Scale (HCS) scale. Effect of protocol on patient satisfaction was assessed with a specific questionnaire at the time of colonoscopy. Proportion of patients who obtained successful bowel preparation for colonoscopy (HCS A or B) was significantly higher in the SPA group than in the control group (100% vs 96.1%, respectively; P = 0.037). Mean global HCS scores were similar in both groups. Patient-reported tolerability and overall experience with the prescribed bowel preparation were significantly higher for the SPA group than for the control group. Successful cleansing and patient acceptability with the use of SPA were superior to written instructions in outpatients submitted for colonoscopy using 2 L PEG solution plus ascorbic acid. © 2015 The Authors.

Individuals with diverticulosis frequently also have irritable bowel syndrome (IBS), but there are no longitudinal data to associate acute diverticulitis with subsequent IBS, functional bowel disorders, or related emotional distress. In patients with postinfectious IBS, gastrointestinal disorders cause long-term symptoms, so we investigated whether diverticulitis might lead to IBS. We compared the incidence of IBS and functional bowel and related affective disorders among patients with diverticulitis. We performed a retrospective study of patients followed up for an average of 6.3 years at a Veteran's Administration medical center. Patients with diverticulitis were identified based on International Classification of Diseases, 9th revision codes, selected for the analysis based on chart review (cases, n = 1102), and matched with patients without diverticulosis (controls, n = 1102). We excluded patients with prior IBS, functional bowel, or mood disorders. We then identified patients who were diagnosed with IBS or functional bowel disorders after the diverticulitis attack, and controls who developed these disorders during the study period. We also collected information on mood disorders, analyzed survival times, and calculated adjusted hazard ratios. Cases were 4.7-fold more likely to be diagnosed later with IBS (95% confidence interval [CI], 1.6-14.0; P = .006), 2.4-fold more likely to be diagnosed later with a functional bowel disorder (95% CI, 1.6-3.6; P mood disorder (CI, 1.4-3.5; P IBS and functional bowel disorders. We propose calling this disorder postdiverticulitis IBS. Diverticulitis appears to predispose patients to long-term gastrointestinal and emotional symptoms after resolution of inflammation; in this way, postdiverticulitis IBS is similar to postinfectious IBS.

Hypothalamic digoxin, hemispheric chemical dominance, and inflammatory bowel disease.

Science.gov (United States)

Kurup, Ravi Kumar; Kurup, Parameswara Achutha

2003-09-01

The isoprenoid pathway produces three key metabolites--endogenous digoxin, dolichol, and ubiquinone. It was considered pertinent to assess the pathway in inflammatory bowel disease (ulcerative colitis and regional ileitis). Since endogenous digoxin can regulate neurotransmitter transport, the pathway and the related cascade were also assessed in individuals with differing hemispheric dominance to find out the role of hemispheric dominance in its pathogenesis. All the patients with inflammatory bowel disease were right-handed/left hemispheric dominant by the dichotic listening test. The following parameters were measured in patients with inflammatory bowel disease and in individuals with differing hemispheric dominance: (1) plasma HMG CoA reductase, digoxin, dolichol, ubiquinone, and magnesium levels; (2) tryptophan/tyrosine catabolic patterns; (3) free-radical metabolism; (4) glycoconjugate metabolism; and (5) membrane composition and RBC membrane Na+-K+ ATPase activity. Statistical analysis was done by ANOVA. In patients with inflammatory bowel disease there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels, and low ubiquinone and elevated free radical levels. There was also an increase in tryptophan catabolites and a reduction in tyrosine catabolites. There was an increase in cholesterol:phospholipid ratio and a reduction in glycoconjugate level of RBC membrane in these groups of patients. Inflammatory bowel disease is associated with an upregulated isoprenoid pathway and elevated digoxin secretion from the hypothalamus. This can contribute to immune activation, defective glycoprotein bowel antigen presentation, and autoimmunity and a schizophreniform psychosis important in its pathogenesis. The biochemical patterns obtained in inflammatory bowel disease is similar to those obtained in left-handed/right hemispheric dominant individuals by the dichotic listening test. But all the patients with peptic ulcer disease were right

To investigate the association between characteristics of individuals with spinal cord injury and neurogenic bowel and their perceived quality of life. The study design is an exploratory, descriptive correlational design. To measure the variables of the study the Quality of Life Survey developed by Randell et al. (2001) was used to measure perceived quality of life related to bowel management. Individual bowel management preferences and subjective costs and benefits of the preferences were gathered through the Neurogenic Bowel Characteristics Survey. PARTICIPANTS/METHOD: Data were collected from a random half of the individuals who met the inclusion criteria from the patient database (n=1193). Two hundred and forty one surveys were analyzed for this study. More than half of the sample (n=134) provided their own bowel management consisting of digital stimulation, suppositories, and other aids; 8% (n=19) had a colostomy. Regardless of the bowel management program 54% (n=127) were satisfied with current methods. Although time reported to complete bowel programs ranged from 1 to 120 minutes, there was no difference in rating of satisfaction with time. There was a statistically significant difference between those satisfied and dissatisfied with current bowel management and quality of life; those satisfied demonstrated a higher quality of life on three subscales, work function (p= .021), bowel problems (p< .001), and social function (p< .001). Those dissatisfied with their bowel program perceived a lower quality of life and indicated problems of time (p= .001), pain or discomfort (p= .033), and poor results (p< .001). Research data provide the patient's perspective on bowel management characteristics, complications, satisfaction, and their perceived quality of life. Results of this research will be incorporated into bowel management education and possible modification of the current inpatient bowel management program. © 2012 Association of Rehabilitation Nurses.

PURPOSE/OBJECTIVE: One of the goals in the treatment of gastrointestinal tract malignancies is to preserve normal bowel function. Evaluation of bowel function to date, however, has been highly subjective and restricted in definition. Presented is a tool that has been validated for use as a more specific assessment of bowel function after therapeutic intervention. MATERIALS AND METHODS: The Bowel Function Self Assessment Tool [BFSAT] was developed from descriptive data obtained from cancer patients who presented with problems related to bowel function. The BFSAT and FACT-C scale were administered to 134 patients with colorectal cancer. Prior treatment had included radiation, administered either alone or in combination with chemotherapy, following surgical resection. RESULTS: Content validity was achieved through the multimodality review panel process. Based on descriptors provided by patients, publications and a multimodality review panel who screened the items for clarity and content, 29 of the initial 40 items were unanimously agreed upon and included in the questionnaire. A correlation of 0.51, which is significant beyond the 0.001 level, was obtained between the BFSAT and the FACT-C, indicating strong concurrent validity. The internal consistency and reliability was confirmed by coefficient alpha levels of 0.85, which matched the 0.85 coefficient alpha level for the FACT-C scale in this population. Factor analysis will be conducted when a larger sample size is available. CONCLUSION: Baseline reliability and validity have been established for the BFSAT. The BFSAT shows strong correlation with the FACT-C scale. Providing information regarding function and clinical outcome, the BFSAT complements the FACT-C in the evaluation of quality of life parameters among patients with colorectal cancer

The normal small bowel fold is easily seen on conventional studies of the small intestine, but visualization of the small bowel villus is at the limit of resolution of current roentgenographic technique. When the villi are enlarged, they appear radiographically as an irregularity or micronodularity of the small bowel fold. The anatomy of the fold and the pathophysiology of diseases producing fold nodularity (tumor,inflammatory disease, NLH, mastocytosis) and micronodularity (lymphangiectasia, Waldenstrom macroglobulinemia, Whipple disease) are presented, with an emphasis on radiologic-pathologic correlation. The radiologist should suggest certain diseases or conditions based on the roentgenographic characteristics of the closely analyzed small bowel fold

Bowel function in long-term rectal cancer survivors with anastomosis has not been characterized adequately. We hypothesized that bowel function is associated with patient, disease, and treatment characteristics. The cohort study included Kaiser Permanente members who were long-term (≥5 years) rectal cancer survivors with anastomosis. Bowel function was scored using the self-administered, 14-item Memorial Sloan-Kettering Cancer Center Bowel Function Index. Patient, cancer, and treatment variables were collected from the electronic medical chart. We used multiple regression to assess the relationship of patient- and treatment-related variables with the bowel function score. The study included 381 anastomosis patients surveyed an average 12 years after their rectal cancer surgeries. The total bowel function score averaged 53 (standard deviation, 9; range, 31-70, higher scores represent better function). Independent factors associated with worse total bowel function score included receipt of radiation therapy (yes vs. no: 5.3-unit decrement, p 6 cm: 3.2-unit decrement, p decrement, p decrement, p model explained 20% of the variation in the total bowel function score. Low tumor location, radiation therapy, temporary ostomy during initial treatment, and history of smoking were linked with decreased long-term bowel function following an anastomosis. These results should improve decision-making about surgical options.

111 In-labelled leucocytes were used to obtain gamma camera images of inflamed of bowel in a wide variety of inflammatory bowel disease. No false positive scans were observed in the irritable bowel syndrome and in bowel malignancy. All patients with moderate or severely active disease had positive scans. Faecal excretion of 111 Indium increased with disease severity. 111 In-tropolone labelling appeared to offer the advantage over 111 In-acac labelling in localising inflamed bowel earlier. In many cases the bowel was imaged within 40 min of re-injection of the leucocytes. 111 In-leucocyte scanning provides a novel approach to the problem of diagnosis and assessment of inflammatory bowel disease. It is non-invasive, requires no bowel preparation and thus is safe in the acutely sick patient where conventional radiological imaging methods may be hazardous. 111 Indium faecal excretion provides an objective assessment of disease activity which should prove useful in evaluating treatment regimes

Effective clinical imaging of the small intestine is accomplished only with methods capable of accurately demonstrating bowel morphology. The two major approaches to barium enema examination of this segment of gut - orally and enteroclysis - will be described and illustrated with short videotape presentations. Pursued vigorously and with interest, both methods can yield excellent results in an efficient manner. Careful execution of the examination rather than use of a particular methodology is probably the most important factor in realizing such results. However, each method has its advantages and disadvantages, and these will be presented and discussed. A cursory small bowel examination has no role in modern medicine. Radiologists assume primary responsibility for the diagnostic evaluation of the small bowel and should strive to refine and advance the accuracy of the examination

Inflammatory bowel disease is a global disease in the 21st century. We aimed to assess the changing incidence and prevalence of inflammatory bowel disease around the world. We searched MEDLINE and Embase up to and including Dec 31, 2016, to identify observational, population-based studies reporting the incidence or prevalence of Crohn's disease or ulcerative colitis from 1990 or later. A study was regarded as population-based if it involved all residents within a specific area and the patients were representative of that area. To be included in the systematic review, ulcerative colitis and Crohn's disease needed to be reported separately. Studies that did not report original data and studies that reported only the incidence or prevalence of paediatric-onset inflammatory bowel disease (diagnosis at age incidence (119 studies) and prevalence (69 studies) of Crohn's disease and ulcerative colitis. We used temporal trend analyses to report changes as an annual percentage change (APC) with 95% CI. We identified 147 studies that were eligible for final inclusion in the systematic review, including 119 studies of incidence and 69 studies of prevalence. The highest reported prevalence values were in Europe (ulcerative colitis 505 per 100 000 in Norway; Crohn's disease 322 per 100 000 in Germany) and North America (ulcerative colitis 286 per 100 000 in the USA; Crohn's disease 319 per 100 000 in Canada). The prevalence of inflammatory bowel disease exceeded 0·3% in North America, Oceania, and many countries in Europe. Overall, 16 (72·7%) of 22 studies on Crohn's disease and 15 (83·3%) of 18 studies on ulcerative colitis reported stable or decreasing incidence of inflammatory bowel disease in North America and Europe. Since 1990, incidence has been rising in newly industrialised countries in Africa, Asia, and South America, including Brazil (APC for Crohn's disease +11·1% [95% CI 4·8-17·8] and APC for ulcerative colitis +14·9% [10·4-19·6]) and Taiwan (APC

The Internet is a widely used information resource for patients with inflammatory bowel disease, but there is variation in the quality of Web sites that have patient information regarding Crohn's disease and ulcerative colitis. The purpose of the current study is to systematically evaluate the quality of these Web sites. The top 50 Web sites appearing in Google using the terms "Crohn's disease" or "ulcerative colitis" were included in the study. Web sites were evaluated using a (a) Quality Evaluation Instrument (QEI) that awarded Web sites points (0-107) for specific information on various aspects of inflammatory bowel disease, (b) a five-point Global Quality Score (GQS), (c) two reading grade level scores, and (d) a six-point integrity score. Thirty-four Web sites met the inclusion criteria, 16 Web sites were excluded because they were portals or non-IBD oriented. The median QEI score was 57 with five Web sites scoring higher than 75 points. The median Global Quality Score was 2.0 with five Web sites achieving scores of 4 or 5. The average reading grade level score was 11.2. The median integrity score was 3.0. There is marked variation in the quality of the Web sites containing information on Crohn's disease and ulcerative colitis. Many Web sites suffered from poor quality but there were five high-scoring Web sites.

For radiotherapy in rectal cancer patients treated with small bowel displacement device (SBDD) and belly board, We will suggest new indication of using SBDD depending on obesity index by analyzing correlation between obesity and irradiated small bowel volume. In this study, We reviewed 29 rectal cancer patients who received pelvic radiation therapy with belly board and SBDD from January to April in 2012. We only analyzed those patients treated with three-field technique (PA and both LAT) on 45 Gy (1.8 Gy/fx). We measured patients' height, weight, body mass index (BMI), waist-hip ratio (WHR) and divided BMI into two groups.(≥23:BMI=group 1, <23:BMI=group 2) We performed a statistical analysis to evaluate correlation between total volume of bladder (TV{sub bldder}), obesity index and high dose volume of small bowel (small bowel volume irradiated at 90% of prescribed dose, HDV{sub sb}), low dose volume of small bowel (small bowel volume irradiated at 33% of prescribed dose, LDV{sub sb}). The result shows, gender, WHR and status of pre operative or post operative do not greatly affect HDV{sub sb} and LDV{sub sb}. Statistical result shows, there are significant correlation between HDV{sub sb} and BMI (p<0.04), HDV{sub sb} and TV{sub bladder} (p<0.01), LDV{sub sb} and TV{sub bladder} (p<0.01). BMI seems to correlate with HDV{sub sb} but does not with LDV{sub sb} (p>0.05). There are negative correlation between HDV{sub sb} and BMI, TV{sub bladder} and HDV{sub sb}, TV{sub bladder} and LDV{sub sb} . Especially, BMI group1 has more effective and negative correlation with HDV{sub sb} (p=0.027) than in BMI group 2. In the case of BMI group 1, TV{sub bladder} has significant negative correlation with HDV{sub sb} and LDV{sub sb} (p<0.04). In conclusions, we confirmed that Using SBDD with belly board in BMI group 1 could more effectively reduce irradiated small bowel volume in radiation therapy for rectal cancer. Therefore, We suggest using belly board with SBDD in order

Surgical site infections (SSIs), such as wound infection, fascial dehiscence, and intraabdominal abscess, commonly occur following penetrating abdominal trauma. However, most of the literature involves penetrating colon injuries. There are few reports describing complications following penetrating stomach and small bowel injuries. Based on the hypothesis that SSIs are commonly found following penetrating stomach and small bowel trauma, a prospective observational study was performed at an academic Level I trauma center from March 1, 2004 until August 31, 2006. The subjects were patients who had sustained a penetrating injury to the stomach or small bowel. Patients were followed for the development of an SSI, defined as wound infection, fascial dehiscence, or intraabdominal abscess. A total of 178 patients were admitted with penetrating stomach or small bowel injuries over the 29-month period. There were 121 (68%) gunshot injuries and 57 (32%) stab wounds. Associated intraabdominal injuries occurred in 74% of patients. Overall, SSIs occurred in 20% of cases. Risk factors for SSI included associated duodenal or colon injury, whereas time to operating room, blood loss, and type and duration of antibiotic use were not. When associated colon injuries were excluded, SSIs occurred in 16% of patients with gastric injuries and 13% of those with small bowel injuries. SSIs commonly follow penetrating stomach and small bowel trauma. Risk factors for SSI include associated duodenal or colon injury. Delay to operating room, blood loss, and type and length of antibiotic prophylaxis were not associated with an increased risk of SSI.

Irritable bowel syndrome is the most frequent functional disorder of the digestive system. Patients with irritable bowel syndrome have motor disorders not only in the colon, but also in other parts of the digestive tract such as the oesophagus and small intestine; however, it is not known whether the stomach is also involved. We used a radiolabelled mixed solid-liquid meal (technetium-99m for the solid component, indium-111 for the liquid component) to study gastric emptying of solids (GES), liquids (GEL) and indigestible solids (GER) in 50 patients diagnosed as having irritable bowel syndrome (30 with predominant constipation and 20 with predominant diarrhoea). GER was measured by counting the number of indigestible solids remaining in the stomach 4 h after they were swallowed. In patients with irritable bowel syndrome, GES and GEL were slower than in control subjects (P<0.05). GER was normal in all patients except for two women. Thirty-two patients (64%) showed delayed GES, 29 (58%) delayed GEL, and 2 (4%) delayed GER. Among patients with irritable bowel syndrome, GES was slower in those with predominant constipation than in those with predominant diarrhoea (P<0.05); GEL and GER were similar in both groups. Gastroparesis was found in a large proportion of patients with irritable bowel syndrome, suggesting the presence of a more generalised motor disorder of the gut. (orig.)

Despite having optimal pull-through (PT) surgery for Hirschsprung's disease (HSCR), many patients experience persistent bowel symptoms with no mechanical/histopathological cause. Murine models of HSCR suggest that expression of key neurotransmitters is unbalanced proximal to the aganglionic colonic segment. We aimed to investigate expression of key enteric neurotransmitters in the colon of children with HSCR. Full-length PT specimens were collected fresh from children with HSCR (n=10). Control specimens were collected at colostomy closure from children with anorectal malformation (n=8). The distributions of neuronal nitric oxide synthase (nNOS), choline acetyltransferase (ChAT), vasoactive intestinal peptide (VIP), and substance P (SP) were evaluated using immunofluorescence and confocal microscopy. Neurotransmitter quantification was with Western blot analysis. ChAT expression was high in aganglionic bowel and transition zone but reduced in ganglionic bowel in HSCR relative to controls. Conversely, nNOS expression was markedly reduced in aganglionic bowel but high in ganglionic bowel in HSCR relative to controls. VIP expression was similar in ganglionic HSCR and control colon. SP expression was similar in all tissue types. Imbalance of key excitatory and inhibitory neurotransmitters in the ganglionic bowel in HSCR may explain the basis of bowel dysmotility after an optimal pull-through operation in some patients.

The relevance of diet in both the pathogenesis and the therapy of inflammatory bowel disease is an evolving science. Disturbance of intestinal microflora (dysbiosis) is putatively a key element in the environmental component causing inflammatory bowel disease. Prebiotics are among the dietary components used in an attempt to counteract dysbiosis. Such predominantly carbohydrate dietary components exert effects on the luminal environment by physicochemical changes through pH alteration, by pro...

To evaluate the usefulness of CT for the diagnosis of the cause and localization of small bowel obstruction. Out of a group of children who underwent a CT examination for a suspected small bowel obstruction, 19 patients with confirmed underlying disorders were identified and included in the study. Neonates and patients with duodenal obstruction were excluded from the study. The CT findings were analyzed for the location of obstruction site, abnormalities of the mesentery and mesenteric vessels, bowel wall thickening, closed loop obstruction, and strangulation. The obstruction site was divided into five parts. The preoperative CT diagnosis was compared with the final diagnosis. Causes of small bowel obstruction were intussusception (n = 6), appendiceal perforation (n = 4), transmesenteric internal hernia (n = 2), postoperative bands (n = 1), idiopathic multiple bands (n = 1), a foreign body (n = 1), a small bowel adenocarcinoma (n = 1), Meckel's diverticulitis (n = 1), tuberculous peritonitis (n = 1) and Salmonella enteritis with bowel perforation (n = 1). The CT findings showed mesenteric vascular prominence (n = 13), omental or mesenteric infiltration (n = 10), localized bowel wall thickening (n = 7) closed loops obstruction (n = 3) and strangulation (n = 1). The obstruction site was identified in all cases. The causes of obstruction could be diagnosed preoperatively in 14 cases, but a preoperative diagnosis was difficult in 5 cases. The causes of small bowel obstruction in children are variable, and CT is useful for evaluating the cause and localization of small bowel obstruction

To evaluate the diagnostic criteria for differentiation between benign and malignant bowel wall lesions on ultrasonogram (US) and CT. We prospectively analyzed 55 bowel lesions on US and CT, including 29 cases of benign lesion and 26 cases of malignant lesion. The thickness and length of the lesions were measured and the bowel features were classified into four categories : a) obliteration of bowel wall layers, b) marginal irregularity, c)eccentric wall thickening, and d) heterogeneous perilesional fat changes. We analyzed the sensitivity, specificity, positive and negative predictive values of each criterion. The mean thickness of malignant bovel lesions was 1.77 / 1.84 cm on US/CT, and that of benign lesions was 0.71 / 0.80 cm on US/CT. There was statistically significant difference in thickness between benign and malignant lesions (P<.05). The statistical analysis of incremental study showed that the most sensitive and specific criteria for malignant lesions were more than 1.2cm in thickness and less than 5.0cm in length. Among feature criteria, bowel wall obliteration, irregular margin and eccentric contour were statistically and significantly different between benign and malignant lesions (P<.05). The most sensitive and specific feature criterion was the bowel wall obliteration. The most sensitive and specific criteria for differentiation between benign and malignant bowel lesions were thickness and obliteration of bowel wall layers. Particularly, US was useful for the detection of bowel wall layers

Objective: Celiac disease (CD) is a common, lifelong disease with small bowel malabsorption based on genetically conditioned gluten intolerance. The clinical manifestation could be very heterogeneous. The proof of celiac disease is now based mainly on clinical and laboratory (antibodies and enterobiopsy) signs, which are in some cases problematic and inconvenient. Materials and methods: In our study we have examined 250 patients with suspection or with proven celiac disease and we evaluated specific ultrasound small bowel changes in this group. In the next step, we chose 59 patients with laboratory proved celiac disease and we statistically compared ultrasound, other laboratory and clinical findings in different forms and stages of the disease. Results: Specific small bowel pathologies in patients with celiac disease (like changes of intestinal villi in different parts of small bowel, abnormal peristalsis and mesenterial lymphadenopathy) can be well visualized by ultrasound and in combination with clinical and laboratory signs ultrasound examination could have an important role in screening, determination of diagnosis and monitoring of patients with different forms of celiac disease.

The causes of obstruction are diverse with varied embryological origins, and some underlying etiologies are not yet well described. Some findings of neonatal bowel obstruction can be detected prenatally on ultrasound imaging. The obstruction is classified as “high” when the level of obstruction is proximal to the ileum, and “low” when the level of obstruction is at the ileum or colon. Early diagnosis of the type of intestinal obstruction and localization of the obstructive bowel segment guides timely and appropriate management of the underlying pathologic entity. Neonatal bowel obstructions are ideally managed at specialized centers with a large volume of neonatal surgery and dedicated pediatric surgical and anesthesia expertise. Although surgical intervention is necessary in most cases, initial management strategies often target underlying metabolic, cardiac, or respiratory abnormalities. Imaging plays a key role in early and accurate diagnosis of the abnormalities. When bowel obstruction is suspected clinically, initial imaging workup usually involves abdominal radiography, which may direct further evaluation with fluoroscopic examination such as upper gastrointestinal (UGI contrast study or contrast enema. This article provides a comprehensive review of clinical and radiological features of common and less common causes of intestinal obstruction in the neonatal age group, including esophageal atresia, enteric duplication cysts, gastric volvulus, congenital microgastria, hypertrophic pyloric stenosis, duodenal atresia

Arteriovenous Malformation Detected by Small Bowel Endoscopy

Directory of Open Access Journals (Sweden)

Takaaki Fujii

2014-10-01

Full Text Available Gastrointestinal bleeding that originates in the small intestine is often difficult to diagnose. When successful diagnosis reveals a lesion that can be localized preoperatively, the laparoscopic approach is an appropriate and beneficial treatment modality for small bowel resection. A 69-year-old man presented with a 6-month history of gastrointestinal bleeding and symptomatic transfusion-dependent anemia. Upper and lower endoscopy were normal. Double-balloon endoscopy established the source of the bleeding as a 0.5-cm polypoid mass appearing as a submucosal tumor with redness and pulsation in the lower ileum, suggesting a vascular lesion. Laparoscopic small bowel resection was successful in removing the mass in the ileum. Histological evaluation of the mass revealed an arteriovenous malformation. Preoperative small bowel endoscopy can be useful for diagnosing the cause and localization of arteriovenous malformation in the small intestine.

To describe the sonographic (US) and clinical features of spontaneously reduced small bowel intussusception, and to discuss the management options for small bowel intussusception based on US findings with clinical correlation. During a five years of period, 34 small bowel intussusceptions were diagnosed on US in 32 infants and children. The clinical presentations and imaging findings of the patients were reviewed. The clinical presentations included abdominal pain or irritability (n = 25), vomiting (n 5), diarrhea (n = 3), bloody stool (n = 1), and abdominal distension (n = 1), in combination or alone. US showed multi-layered round masses of small (mean, 1.5 ± 0.3 cm) diameters and with thin (mean, 3.5 ± 1 mm) outer rims along the course of the small bowel. The mean length was 1.8 ± 0.5 cm and peristalsis was seen on the video records. There were no visible lead points. The vascular flow signal appeared on color Doppler images in all 21 patients examined. Spontaneous reduction was confirmed by combinations of US (n = 28), small bowel series (n = 6), CT scan (n = 3), and surgical exploration (n 2). All patients discharged with improved condition. Typical US findings of the transient small bowel intussusception included 1) small size without wall swelling, 2) short segment, 3) preserved wall motion, and 4) absence of the lead point. Conservative management with US monitoring rather than an immediate operation is recommended for those patient with typical transient small bowel intussusceptions. Atypical US findings or clinical deterioration of the patient with persistent intussusception warrant surgical exploration

Contouring and Constraining Bowel on a Full-Bladder Computed Tomography Scan May Not Reflect Treatment Bowel Position and Dose Certainty in Gynecologic External Beam Radiation Therapy

Purpose: To evaluate, in a gynecologic cancer setting, changes in bowel position, dose-volume parameters, and biological indices that arise between full-bladder (FB) and empty-bladder (EB) treatment situations; and to evaluate, using cone beam computed tomography (CT), the validity of FB treatment presumption. Methods and Materials: Seventeen gynecologic cancer patients were retrospectively analyzed. Empty-bladder and FB CTs were obtained. Full-bladder CTs were used for planning and dose optimization. Patients were given FB instructions for treatment. For the study purpose, bowel was contoured on the EB CTs for all patients. Bowel position and volume changes between FB and EB states were determined. Full-bladder plans were applied on EB CTs for determining bowel dose-volume changes in EB state. Biological indices (generalized equivalent uniform dose and normal tissue complication probability) were calculated and compared between FB and EB. Weekly cone beam CT data were available in 6 patients to assess bladder volume at treatment. Results: Average (±SD) planned bladder volume was 299.7 ± 68.5 cm{sup 3}. Median bowel shift in the craniocaudal direction between FB and EB was 12.5 mm (range, 3-30 mm), and corresponding increase in exposed bowel volume was 151.3 cm{sup 3} (range, 74.3-251.4 cm{sup 3}). Absolute bowel volumes receiving 45 Gy were higher for EB compared with FB (mean 328.0 ± 174.8 vs 176.0 ± 87.5 cm{sup 3}; P=.0038). Bowel normal tissue complication probability increased 1.5× to 23.5× when FB planned treatments were applied in the EB state. For the study, the mean percentage value of relative bladder volume at treatment was 32%. Conclusions: Full-bladder planning does not necessarily translate into FB treatments, with a patient tendency toward EB. Given the uncertainty in daily control over bladder volume for treatment, we strongly recommend a “planning-at-risk volume bowel” (PRV{sub B}owel) concept to account for bowel motion

Systematic review: Complementary and alternative medicine in the irritable bowel syndrome.

LENUS (Irish Health Repository)

Hussain, Z

BACKGROUND: Complementary and alternative medical therapies and practices are widely employed in the treatment of the irritable bowel syndrome. AIM: To review the usage of complementary and alternative medicine in the irritable bowel syndrome, and to assess critically the basis and evidence for its use. METHODS: A systematic review of complementary and alternative medical therapies and practices in the irritable bowel syndrome was performed based on literature obtained through a Medline search. RESULTS: A wide variety of complementary and alternative medical practices and therapies are commonly employed by irritable bowel syndrome patients both in conjunction with and in lieu of conventional therapies. As many of these therapies have not been subjected to controlled clinical trials, some, at least, of their efficacy may reflect the high-placebo response rate that is characteristic of irritable bowel syndrome. Of those that have been subjected to clinical trials most have involved small poor quality studies. There is, however, evidence to support efficacy for hypnotherapy, some forms of herbal therapy and certain probiotics in irritable bowel syndrome. CONCLUSIONS: Doctors caring for irritable bowel syndrome patients need to recognize the near ubiquity of complementary and alternative medical use among this population and the basis for its use. All complementary and alternative medicine is not the same and some, such as hypnotherapy, forms of herbal therapy, specific diets and probiotics, may well have efficacy in irritable bowel syndrome. Above all, we need more science and more controlled studies; the absence of truly randomized placebo-controlled trials for many of these therapies has limited meaningful progress in this area.

The aim of the study is to explore the prevalence of gingival signs of inflammation and its relationship to oral cleanliness and age among Special Olympics athletes from Europe and Eurasia. A retrospective longitudinal study was performed with data collected through standardized oral from 15.941 athletes from annual Special Olympics events held in 49 countries, from Europe and Eurasia between 2007 and 2012. The data was analysed descriptively, with One-Way ANOVA test and Chi-Square test. The level of significance was predetermined at a p value < 0.05. A total of 7,754 athletes presented with gingival signs (48.64%). There were no significant differences (p= 0,095) in mean gingival signs between age groups, however the association between mouth cleaning and age, was statistically significant. The data suggests that there is a high prevalence of gingival signs among individuals with special needs; over 50% in more than 20 countries. Therefore, there is a serious need for education and preventive programs for the patients, their parents and caregivers.

Until recently, no studies have prospectively evaluated bowel function after sphincter-preserving surgery for rectal cancer with the use of a validated bowel function scoring system. The aim of this study was to investigate possible risk factors for altered bowel function after sphincter-preserving surgery. This was a prospective study. The study was conducted between January 2006 and May 2012 at the authors' institution. Patients who underwent sphincter-preserving rectal cancer surgery were recruited. Bowel function was assessed 1 day before (baseline) and at 1 year after sphincter-preserving surgery or temporary ileostomy takedown with the use of the Memorial Sloan Kettering Cancer Center questionnaire. Multivariable analysis was performed to identify the factors associated with altered bowel function after surgery. Overall, 266 patients were eligible for the analysis. The tumor was located in the upper, middle, and lower rectum in 68 (25.5%), 113 (42.5%), and 85 (32.0%) patients. Intersphincteric resection and temporary ileostomy were performed in 18 (6.8%) and 129 (48.5%) patients. The mean Memorial Sloan Kettering Cancer Center score was 64.5 ± 7.6 at 1 year after sphincter-preserving surgery or temporary ileostomy takedown. The Memorial Sloan Kettering Cancer Center score decreased in 163/266 patients (61.3%) between baseline and 1 year after surgery. Tumor location (p = 0.01), operative method (p = 0.03), anastomotic type (p = 0.01), and temporary ileostomy (p = 0.01) were associated with altered bowel function after sphincter-preserving surgery in univariate analyses. In multivariable analysis, only tumor location was independently associated with impaired bowel function after sphincter-preserving rectal cancer surgery. This study was limited by its nonrandomized design and the lack of measurement before preoperative chemoradiotherapy. We suggest that preoperative counseling should be implemented to inform patients of the risk of bowel dysfunction

Examinations using ionizing radiation are frequently used in the evaluation of disease activity in children affected by idiopathic inflammatory bowel disease (IBD). To develop an MR imaging protocol without the need for fluoroscopic insertion of an enteral tube and to assess the disease activity in children with IBD. Included in the study were 37 children (22 girls and 15 boys; age range 7-15 years, mean 11.67 years) with IBD who underwent MR imaging of the small bowel. Of these 37 children, 32 had Crohn disease and 5 had indeterminate colitis. A water solution containing herbal fibres was administered orally or through a nasogastric tube. Patients were imaged on a 1.5-T MR scanner with T1-weighted and Τ2-weighted sequences followed by a dynamic study using 3-D T1-W images after intravenous administration of gadolinium. The percentage enhancement of the bowel wall was significantly increased in patients with abnormal C-reactive protein (CRP) values compared to patients with CRP values in the normal range (P<0.001). A relatively weak but significant correlation between percentage enhancement of the bowel wall and CRP values was noted during all phases of enhancement. This MR imaging protocol is a safe and well-tolerated method for evaluating disease activity and extraintestinal manifestations of IBD in children. (orig.)

High-quality bowel preparation is essential for successful outpatient colonoscopy. Currently, the rate of adequate bowel preparation for outpatient colonoscopy in the USA is low. Patients often fail to adhere to recommended preparation instructions. Limited literature exists on evaluating educational intervention as a means of improving the quality of bowel preparation prior to outpatient colonoscopy. Our objective was to determine the effect of an educational intervention on the quality of outpatient colonoscopy preparation. The secondary objective was to determine whether the quality of bowel preparation improves overall colonoscopy outcomes as measured by rate of polyp detection and caecal intubation time. A single-blinded, prospective, randomised, controlled trial was conducted in two inner-city gastroenterology clinics in the USA. One hundred and sixty-four subjects were enrolled and randomly assigned to one of two groups. The control group subjects received verbal and written instructions for colonoscopy. The intervention group subjects received the same instructions and were then asked to answer a questionnaire. The subjects' responses were reviewed and an additional explanation of the preparation process provided. An attending gastroenterologist determined the quality of each bowel preparation at the time of colonoscopy using the Universal Preparation Assessment Scale. The educational intervention had no impact on the overall quality of bowel preparation (P=0.12). However, the type of food (liquid vs solid) consumed during the 24 hours prior to the procedure (P=0.04) and the time since the last solid meal (P=0.03) did have an impact on preparation quality. Other significant factors included elapsed time to first bowel movement from the initiation of bowel preparation (P=0.05) and age younger than 55 (P=0.02). Adequate bowel preparation was associated with shorter total procedure (P=0.001) and caecal intubation (P=0.01) times. Our study failed to demonstrate

To analyse the effect of mechanical bowel preparation vs no mechanical bowel preparation on outcome in patients undergoing elective colorectal surgery. Meta-analysis of randomised controlled trials and observational studies comparing adult patients receiving mechanical bowel preparation with those receiving no mechanical bowel preparation, subdivided into those receiving a single rectal enema and those who received no preparation at all prior to elective colorectal surgery. A total of 36 studies (23 randomised controlled trials and 13 observational studies) including 21568 patients undergoing elective colorectal surgery were included. When all studies were considered, mechanical bowel preparation was not associated with any significant difference in anastomotic leak rates (OR = 0.90, 95%CI: 0.74 to 1.10, P = 0.32), surgical site infection (OR = 0.99, 95%CI: 0.80 to 1.24, P = 0.96), intra-abdominal collection (OR = 0.86, 95%CI: 0.63 to 1.17, P = 0.34), mortality (OR = 0.85, 95%CI: 0.57 to 1.27, P = 0.43), reoperation (OR = 0.91, 95%CI: 0.75 to 1.12, P = 0.38) or hospital length of stay (overall mean difference 0.11 d, 95%CI: -0.51 to 0.73, P = 0.72), when compared with no mechanical bowel preparation, nor when evidence from just randomized controlled trials was analysed. A sub-analysis of mechanical bowel preparation vs absolutely no preparation or a single rectal enema similarly revealed no differences in clinical outcome measures. In the most comprehensive meta-analysis of mechanical bowel preparation in elective colorectal surgery to date, this study has suggested that the use of mechanical bowel preparation does not affect the incidence of postoperative complications when compared with no preparation. Hence, mechanical bowel preparation should not be administered routinely prior to elective colorectal surgery.

Inflammatory bowel disease.

Inflammatory bowel disease (IBD) is increasing in frequency in Australia. General practitioners play an important role in early diagnosis and in a multidisciplinary approach to managing such patients. Keeping abreast of evolving concepts, particularly in treatment, is challenging. This article aims to address key issues in diagnosis and management to better equip general practitioners for their role in multidisciplinary management of patients with IBD. Making the diagnosis can be difficult, but is facilitated by appropriate clinical suspicion and sensible judgment as to who undergoes diagnostic tests such as colonoscopy. Treatment of ulcerative colitis has changed little in recent years, except for our improved ability to deliver mesalazine to the large bowel via the recent availability of several oral and rectal preparations. Prevention of relapse using these is an important strategy in the majority of patients. Treatment of Crohn disease is changing due to more realistic concepts of the natural history of the disease and the development of new, powerful anti-inflammatory therapies. Attention to issues other than intestinal inflammation such as nutrition, education and counselling, remain important in achieving optimal management.

Inflammatory bowel disease and colorectal cancer

Directory of Open Access Journals (Sweden)

Andreja Ocepek

Full Text Available Background: Colorectal cancer is one of the most frequent cancers in developed countries and Slovenia, and the incidence is still rising. Groups of people with higher risk for colorectal cancer are well defined. Among them are patients with inflammatory bowel disease. The risk is highest in patients in whom whole large bowel is affected by inflammation, it rises after 8 to 10 years and increases with the duration of the disease. Precancerous lesion is a displastic, chronically inflammed mucosa and not an adenoma as in cases of sporadic colorectal carcinoma.Conclusions: Many studies suggest that the influence of genetic factors differs between sporadic and inflammatory bowel disease related colorectal cancer. Symptomatic patients at the time of diagnosis have a much worse prognosis. The goal of prevention programes is therefore discovering early precancerous lesions. Established screening protocols are based on relatively frequent colonoscopies which are inconvinient for the patient as well as the endoscopist. Use of specific genetic markers, mutations of candidate genes, as a screening method and a prognostic predictor could greatly lighten therapeutic decisions.

Rotary bending as a mean for improving micro-cleanliness of stainless steels for high demanding applications

Directory of Open Access Journals (Sweden)

Sourisseau Thomas

2018-01-01

Full Text Available Stainless steels are used for automotive or medical applications which require a high fatigue resistance correlated to a high level of micro-cleanliness. A methodology based on rotary bending tests carried out on wires or bars has been defined to determine the material’s endurance limit (after 100 millions cycles and identify the largest subcutaneous inclusions or precipitates where failures initiate. This methodology has been applied to EN 1.4568 spring wires. Failures were found to initiate both at oxide inclusions and AlN precipitates. For the same size, AlN precipitates were observed to be more critical towards crack initiation than oxide inclusions, due to their angular shape and lower thermal expansion at high temperatures. However, oxide inclusions larger than the AlN maximum size strongly impact the material’s fatigue limit, and their density and size should be reduced.

Small Bowel Obstruction due to Intestinal Xanthomatosis

Directory of Open Access Journals (Sweden)

L. E. Barrera-Herrera

2015-01-01

Full Text Available Vast majority of bowel obstruction is due to postoperative adhesions, malignancy, intestinal inflammatory disease, and hernias; however, knowledge of other uncommon causes is critical to establish a prompt treatment and decrease mortality. Xanthomatosis is produced by accumulation of cholesterol-rich foamy macrophages. Intestinal xanthomatosis is an uncommon nonneoplastic lesion that may cause small bowel obstruction and several cases have been reported in the English literature as obstruction in the jejunum. We report a case of small intestinal xanthomatosis occurring in a 51-year-old female who presented with one day of copious vomiting and intermittent abdominal pain. Radiologic images revealed jejunal loop thickening and inflammatory changes suggestive of foreign body obstruction, diagnostic laparoscopy found two strictures at the jejunum, and a pathologic examination confirmed a segmental small bowel xanthomatosis. This case illustrates that obstruction even without predisposing factors such as hyperlipidemia or lymphoproliferative disorders.

Extensive small bowel intramural haematoma secondary to warfarin.

Intramural haematoma is a rare complication of oral anticoagulant therapy, occurring in  1 in 2500 patients treated with warfarin. This report describes a 71-year-old gentleman who presented with tachycardia, vomiting and abdominal distension on a background of anticoagulation for a metallic aortic valve. He was found to have a supratherapeutic international normalized ratio (INR) of 9.9 with an extensive small bowel intramural haematoma and secondary small bowel obstruction. He was successfully managed non-operatively with fluid resuscitation, INR reversal, bowel rest and nasogastric decompression. The patient's presentation was atypical with a lack of classic symptoms such as abdominal pain. This highlights the importance of considering intramural haematoma as a differential diagnosis for gastrointestinal symptoms in anticoagulated patients.

We evaluated the CT criteria useful for the diagnosis of the site of bowel perforation in patients with this or mesenteric injury caused by blunt abdominal trauma. CT findings of 26 patients with blunt abdominal trauma were retrospectively analyzed by two observers who were unaware of operative findings, and the results of their analysis were compared with those findings. Twenty cases of bowel perforation found at the jejunum (8), ileum (9), and colon (3), and six cases of mesenteric injuries were confirmed by operation. We evaluated CT findings of 1) segmental bowel wall thickening, b) focal mesenteric fat infiltration, c) loculated fluid collection and d) extraluminal air adjacent to the bowel, and in addition analyzed the locations of ascites and free air, and the associated injuries of solid organs. The most common finding at the site of bowel perforation was segmental bowel wall thickening (17 cases), followed by focal mesenteric fat infiltration (12 cases), loculated fluid (12 cases) and extraluminal air ajacent to the bowel (9 cases). Segmental bowel wall thickening was present at 34 sites, and the perforations were confirmed at 17 of these(50%). Focal mesenteric fat infiltration was present at 19 sites;the perforations were proven at 12(63%). Loculated fluid collections were confirmed at 12/20 sites(60%), and extraluminal air adjacent to the bowel at 9/12(75%). The positive predictive value of criteria a, b, d, c) was 100%, and the positive predictive values of a, b, c) and a, d) were 60 and 67%, respectively. We observed ascites in 16 cases and intraperitoneal free air in 8 cases, the locations of ascites and free air did not, however, significantly correlate with the perforation sites. Extraluminal air adjacent to the bowel was the most specific criterion, and segmental bowel wall thickening was the most sensitive criterion. of all criteria, the finding 'a, b, c, d' most accurately predicted the site of bowel perforation

Mesenteric lymphangiomas are rare abdominal masses that are seldom associated with small bowel volvulus, and especially in adult patients. We report here on an unusual case of small bowel volvulus that was induced by a mesenteric lymphangioma in a 43-year-old man who suffered from repeated bouts of abdominal pain. At multidetector CT, we noticed whirling of the cystic mesenteric mass and the adjacent small bowel around the superior mesenteric artery. Small bowel volvulus induced by the rotation of the mesenteric lymphangioma was found on exploratory laparotomy. Lymphangioma should be considered as a rare cause of small bowel volvulus in adult patients.

Preoperative Diagnosis of Adult Intussusception Caused by Small Bowel Lipoma

Full Text Available Adult intussusception is rare, accounting for only 5% of all intussusceptions, for which preoperative diagnosis is difficult. We herein report a preoperatively diagnosed case of adult intussusception caused by a small bowel lipoma. A 33-year-old man was admitted to our hospital with three weeks history of colicky epigastric pain. Computed tomography revealed thickening of the ileal wall suggestive of intussusception. Colonoscopy revealed an ileocolic intussusception. Barium enema for reduction of ileocolic intussusception demonstrated a small bowel tumor in the ileum 15 cm proximal to the ileocecal valve. The intussusception was reduced, and the patient underwent partial resection of the ileum encompassing the small bowel tumor. Histological findings confirmed the diagnosis of lipoma of the small bowel. The patient made a satisfactory recovery and remains well.

Recurrent intestinal volvulus in midgut malrotation causing acute bowel obstruction: A case report.

Science.gov (United States)

Sheikh, Fayed; Balarajah, Vickna; Ayantunde, Abraham Abiodun

2013-03-27

Intestinal malrotation occurs when there is a disruption in the normal embryological development of the bowel. The majority of patients present with clinical features in childhood, though rarely a first presentation can take place in adulthood. Recurrent bowel obstruction in patients with previous abdominal operation for midgut malrotation is mostly due to adhesions but very few reported cases have been due to recurrent volvulus. We present the case of a 22-year-old gentleman who had laparotomy in childhood for small bowel volvulus and then presented with acute bowel obstruction. Preoperative computerised tomography scan showed small bowel obstruction and features in keeping with midgut malrotation. Emergency laparotomy findings confirmed midgut malrotation with absent appendix, abnormal location of caecum, ascending colon and small bowel. In addition, there were small bowel volvulus and a segment of terminal ileal stricture. Limited right hemicolectomy was performed with excellent postoperative recovery. This case is presented to illustrate a rare occurrence and raise an awareness of the possibility of dreadful recurrent volvulus even several years following an initial Ladd's procedure for midgut malrotation. Therefore, one will need to exercise a high index of suspicion and this becomes very crucial in order to ensure prompt surgical intervention and thereby preventing an attendant bowel ischaemia with its associated high fatality.

Tc-99m sucralfate scanning for inflammatory bowel disease

Lieberman, L.M.; Becker, S.; Mekhmandarov, S.; Steinmetz, A.

1987-01-01

The authors investigated 14 patients with idiopathic inflammatory bowel disease (IBD) by administering Tc-99m sucralfate (TcS) orally and imaging the abdomen 4 and 24 hours after dose. All patients had either barium radiographic studies or colonoscopy before the scan. The scan identified seven of nine patients who had radiologically demonstrated small-bowel lesions and four of five patients with colonic disease. The authors' preliminary experience suggests that TcS maybe a useful procedure to document location and extent of active disease. It provides information about both small and large bowel in one procedure, is noninvasive, easy to perform, and has low radiation absorbed dose

Change in functional bowel symptoms after prostatectomy: A case-control study

Conclusions: This is the first forward study regarding bowel symptom changes following prostatectomy. The main positive finding of this study is that open prostatectomy was followed by significant increase in diarrhea and bowel habit alternation associated with onset of abdominal pain. Specifically the change was found after open operation but not after TURP. Prostatectomy whether in form of open or transurethral may cause onset of abdominal discomfort and bowel habit change.

To assess the efficacy, tolerability, and safety of hypnosis in adult irritable bowel syndrome by a meta-analysis of randomized controlled trials. Studies were identified by a literature search of the databases Allied and Complementary Medicine Database, Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, PubMed, PsycINFO, and Scopus (from inception to June 30, 2013). Primary outcomes were adequate symptom relief, global gastrointestinal score, and safety. Summary relative risks (RRs) with number needed to treat (NNT) and standardized mean differences (SMDs) with 95% confidence intervals (95% CIs) were calculated using random-effects models. Eight randomized controlled trials with a total of 464 patients and a median of 8.5 (7-12) hypnosis sessions over a median of 12 (5-12) weeks were included into the analysis. At the end of therapy, hypnosis was superior to control conditions in producing adequate symptom relief (RR, 1.69 [95% CI = 1.14-2.51]; NNT, 5 [3-10]) and in reducing global gastrointestinal score (SMD, 0.32 [95% CI = -0.56 to -0.08]). At long-term follow-up, hypnosis was superior to controls in adequate symptom relief (RR, 2.17 [95% CI = 1.22-3.87]; NNT, 3 [2-10]), but not in reducing global gastrointestinal score (SMD, -0.57 [-1.40 to 0.26]). One (0.4%) of 238 patients in the hypnosis group dropped out due to an adverse event (panic attack). This meta-analysis demonstrated that hypnosis was safe and provided long-term adequate symptom relief in 54% of patients with irritable bowel syndrome refractory to conventional therapy.

We wanted to describe the CT findings of small bowel anisakiasis with the pathologic correlation. Four patients with surgically and pathologically proven small bowel anisakiasis were included in this retrospective study. They were three men and one woman and their ages ranged from 28 to 43 years (mean age: 38 years). We evaluated their clinical, CT and histological findings. All the patients had a history of ingesting raw fish within 24 hours from the time of symptom onset. They complained of abdominal pain (n=4), nausea (n=4), vomiting (n=2) and diarrhea (n=1). Physical examination revealed tenderness (n=4), rebound tenderness (n=4) and increased bowel sounds (n=3). Leukocytosis was noted in all the patients on the laboratory examination. None of the patients showed eosinophilia. The CT findings were segmental small bowel wall thickening with preserved layering (n=4), focal segmental luminal narrowing with proximal dilatation (n=4), peritoneal thickening (n=3), mesenteric or omental infiltration (n=4) and varying degrees of ascites (n=4). On the histopathologic examination, they revealed an infiltration of eosinophils (n=4) in all layers of the bowel wall with severe edema. The larvae were found on surgico-pathologic examination in all the cases. The CT findings may be helpful to make the specific diagnosis of small bowel anisakiasis in a patient with the clinical findings of an acute abdomen and a history of eating raw fish

Genetic factors play an important role in the pathogenesis of inflammatory bowel disease. In this review, we will provide an update on the rapid advances in the discovery of inflammatory bowel disease, primarily Crohn's disease, associated genes. Seven recently published Crohn's disease genome-wide association studies have confirmed prior findings related to the nucleotide-binding oligomerization domain 2 (NOD2) gene and the IBD5 locus. In addition, 10 novel loci have been identified and well replicated. Several promising associations between Crohn's disease and gene variants have been identified and replicated, the two most widely replicated being variants in the IL23R and ATG16L1 genes. These findings highlight and further support the importance of the immune system and its interactions with the intestinal microflora in the pathogenesis of inflammatory bowel disease.

Colonoscopy plays an important role in the diagnosis and treatment of gastrointestinal illness in both Western countries and Japan. However, preparative bowel cleansing for colonoscopy is frequently troublesome for elderly and/or constipated patients, since they must drink larger volumes of lavage solution for adequate cleansing. We investigated the use of prokinetic agents for improving the efficacy and tolerability of bowel cleansing prior to colonoscopy. 613 patients were divided into two groups according to oral lavage solution used (polyethylene glycol or magnesium citrate), and were further randomized to receive either vehicle (100 ml water) alone, vehicle with 5 mg mosapride citrate, or vehicle with 50 mg itopride hydrochloride 30 min before administration of lavage solution. Experimental parameters included bowel cleansing quality, times to first defecation and completion of bowel cleansing, and incidence of uncomfortable abdominal symptoms during colonoscopy preparation. Administration of mosapride citrate or itopride hydrochloride prior to oral lavage solution did not significantly improve bowel cleansing quality. However, statistically significantly fewer uncomfortable abdominal symptoms were found in patients who received mosapride citrate or itopride hydrochloride versus vehicle alone. Prokinetic agents effectively decreased the incidence of uncomfortable abdominal symptoms experienced during colonoscopy preparation. Copyright 2008 S. Karger AG, Basel.

Full Text Available Background: While many bowel resections in developed countries are due to congenital anomalies, indications for bowel resections in developing countries are mainly from preventable causes. The aim of the following study was to assess the indications for, morbidity and mortality following preventable bowel resection in our centre. Patients and Methods: Retrospective analysis of all cases of bowel resection deemed preventable in children from birth to 18 years from June 2005 to June 2012. Results: There were 22 preventable bowel resections with an age range of 7 days to 17 years (median 6 months and male:female ratio of 2.1:1. There were 2 neonates, 13 infants and 7 older children. The indications were irreducible/gangrenous intussusceptions (13, abdominal gunshot injury (2, gangrenous umbilical hernia (2, blunt abdominal trauma (1, midgut volvulus (1, necrotizing enterocolitis (1, strangulated inguinal hernia (1, post-operative band intestinal obstructions (1.

MRI of the small bowel is a new method for the assessment of inflammatory bowel diseases. However, inflammatory bowel disease can affect both the small and large bowel. Therefore, our goal was to assess the feasibility of displaying the small bowel and colon simultaneously by MR imaging. Eighteen patients with inflammatory bowel disease were studied. For small bowel distension, patients ingested a solution containing mannitol and locust bean gum. Furthermore, the colon was rectally filled with water. MR examinations were performed on a 1.5-T system. Before and after intravenous gadolinium administration, a T1w data set was collected. All patients underwent conventional colonoscopy as a standard of reference. The oral ingestion and the rectal application of water allowed an assessment of the small bowel and colon in all patients. By means of MRI (endoscopy), 19 (13) inflamed bowel segments in the colon and terminal ileum were detected. Furthermore, eight additional inflammatory lesions in the jejunum and proximal ileum that had not been endoscopically accessible were found by MRI. The simultaneous display of the small and large bowel by MRI is feasible. Major advantages of the proposed MR concept are related to its non-invasive character as well as to the potential to visualize parts of the small bowel that cannot be reached by endoscopy. (orig.)

Full Text Available IntroductionThe purpose of this retrospective study was to report neurological manifestations noted in patients who were monitored for inflammatory bowel disease, in order to document the pathophysiological, clinical, progressive, and therapeutic characteristics of this entity.Material and methodsWe conducted a retrospective study on patients monitored -in the gastroenterology service in Ibn Sina Hospital in Rabat, Morocco- for inflammatory bowel disease from 1992 till 2013 and who developed neurological manifestations during its course. Patients with iatrogenic complications were excluded, as well as patients with cerebrovascular risk factors.ResultsThere were 6 patients, 4 of whom have developed peripheral manifestations. Electromyography enabled the diagnosis to be made and the outcome was favorable with disappearance of clinical manifestations and normalization of the electromyography.The other 2 patients, monitored for Crohn’s disease, developed ischemic stroke. Cerebral computed tomography angiography provided positive and topographic diagnosis. Two patients were admitted to specialized facilities.ConclusionNeurological manifestations in inflammatory bowel disease are rarely reported.  Peripheral neuropathies and stroke remain the most common manifestations. The mechanisms of these manifestations are not clearly defined yet. Currently, we hypothesize the interaction of immune mediators.

Background and Objectives: Irritable bowel syndrome is one of the most common functional gastrointestinal disorders striking 10-20% of the world population. Although most patients do not take medical assistance, this disease enforces significant cost on the patient and health systems and has negative effects on quality of life of the individual. After diagnosis ,treatment of this disease is the next step. Many pathways of treatment has been introduced and the efficacy of each other has been established in one way or another. The first step in the path of treatment is education and confidence of patients that might also be the most important step. Fiber diet, probiotic, anti-cholinergic and anti antispasmodics, laxatives, anti-diarrhea, the drugs affecting serotonin receptors, antidepressants and anti-anxiety, the chloride channel activator and non-drug methods such as cognitive-behavior therapy, hypnotherapy, acupuncture and herbal medicine each of which has been tested on irritable bowel syndrome and efficacy of each one has been indicated in one way or another. This paper tried to outline new treatments available in addition to categorization and discussion of various treatments for irritable bowel syndrome.

Patients with inflammatory bowel disease [IBD] are at increased risk for developing some types of neoplasia. Our aims were to determin the risk for cancer in patients with IBD and to describe the relationship with immunosuppressive therapies and clinical management after tumor diagnosis. Retrospective, multicenter, observational, 5-year follow-up, cohort study. Relative risk [RR] of cancer in the IBD cohort and the background population, therapeutic strategies, and cancer evolution were analyzed. A total of 145 cancers were diagnosed in 133 of 9100 patients with IBD (global cumulative incidence 1.6% vs 2.4% in local population; RR = 0.67; 95% confidence interval [CI]: 0.57-0.78). Patients with IBD had a significantly increased RR of non-melanoma skin cancer [RR = 3.85; 2.53-5.80] and small bowel cancer [RR = 3.70; 1.23-11.13]. After cancer diagnosis, IBD treatment was maintained in 13 of 27 [48.1%] patients on thiopurines, in 2 of 3 on methotrexate [66.6%], none on anti-TNF-α monotherapy [n = 6] and 4 of 12 [33.3%] patients on combined therapy. Rate of death and cancer remission during follow-up did not differ [p > 0.05] between patients who maintained the treatment compared with patients who withdrew [5% vs 8% and 95% vs 74%, respectively]. An association between thiopurines [p = 0.20] or anti-TNF-α drugs [p = 0.77] and cancer was not found. Patients with IBD have an increased risk for non-melanoma skin cancer and small bowel cancer. Immunosuppresive therapy is not related to a higher overall risk for cancer or worse tumor evolution in patients who maintain these drugs after cancer diagnosis.

Comparison of Water, Mannitol and Positive Oral Contrast for Evaluation of Bowel By Computed Tomography

Directory of Open Access Journals (Sweden)

Padhmanaban Elamparidhi

2017-10-01

Full Text Available Introduction: Small bowel remains a challenging anatomical site. Imaging approaches like CT-enterography helps in diagnosing non specific clinical presentations and imaging aids in appropriate management. Hence, bowel evaluation by CT requires a oral contrast agent for diagnosing the bowel pathology. Thus, quantitative and qualitative analysis of three oral contrast agents i.e., water, mannitol and positive contrast was done for identification of ideal intraluminal contrast agent. Aim: To assess the performance of mannitol as an endoluminal contrast agent as compared to water and positive contrast in the evaluation of bowel, to compare the distention of bowel with different oral contrasts and also to assess the usefulness of bowel distension in assessment of mural enhancement pattern of bowel. Materials and Methods: A comparative observational study was performed which consisted of 75 patients who were divided into three groups of 25 patients each. Patients in each group were given 1500 ml of oral contrast. Group I was given mannitol, Group II was given water and Group III was given positive contrast. Assessments of bowel distention at various levels and mural enhancement of bowel were studied. Chisquare test was used as test of significance for qualitative data. ANOVA (Analysis of Variance was the test of significance for quantitative data. Results: Bowel distention was excellent in mannitol compared to water and positive contrast. Wall enhancement and mural pattern was better appreciated with mannitol compared to other two contrast agents. Conclusion: Adequate bowel evaluation by CT requires an oral contrast agent which can cause maximal bowel distention, uniform intraluminal attenuation, increased contrast between intraluminal content and bowel wall with no artifacts and adverse effects. Mannitol has all the above characteristic and can be used as ideal neutral oral contrast agent.

Unusual causes of mechanical small bowel obstruction

We herein report our experience regarding unusual causes of bowel obstruction to increase the awareness of surgeons regarding this disease. From 1991 to 2003, we had experience at the University affiliated hospitals, northern Jordan with 24 patients with small bowel obstruction resulting from unusual causes. We retrospectively reviewed the medical records of these patients with regards to the mode of presentation, cause of obstruction, radiological and operative findings, management and outcome. We recorded 15 patients who underwent previous abdominal surgery. Preoperative diagnosis was correct in only one patient with an internal hernia, but the abdominal CT scan suggested the diagnosis in 5 of the 9 patients who had the scan. The final diagnosis was internal hernias in 11 patients, foreign bodies in 5, ischemic strictures in 3, carcinoid tumors in 2, endometriosis in 2, and metastatic deposit from interstitial bladder carcinoma in one patient. Nine of the 12 patients with recurrent obstruction had either short course or recurrence obstruction during the same hospital admission. W carried out bowel resections in 15 patients (5 resections were due to bowel strangulation). Post operative death occurred in 4 patients. Awareness of these rare causes of intestinal obstruction even in patients with previous abdominal operation might improve the outcome. The tentative diagnosis of adhesion obstruction in patients with unusual obstructive etiology might lead to a higher rate of gangrenous complications. Rigorous preoperative evaluation including careful history and early abdominal CT may show the obstructive cause. (author)

Small Bowel Dose Parameters Predicting Grade ≥3 Acute Toxicity in Rectal Cancer Patients Treated With Neoadjuvant Chemoradiation: An Independent Validation Study Comparing Peritoneal Space Versus Small Bowel Loop Contouring Techniques

Purpose: To determine whether volumes based on contours of the peritoneal space can be used instead of individual small bowel loops to predict for grade ≥3 acute small bowel toxicity in patients with rectal cancer treated with neoadjuvant chemoradiation therapy. Methods and Materials: A standardized contouring method was developed for the peritoneal space and retrospectively applied to the radiation treatment plans of 67 patients treated with neoadjuvant chemoradiation therapy for rectal cancer. Dose-volume histogram (DVH) data were extracted and analyzed against patient toxicity. Receiver operating characteristic analysis and logistic regression were carried out for both contouring methods. Results: Grade ≥3 small bowel toxicity occurred in 16% (11/67) of patients in the study. A highly significant dose-volume relationship between small bowel irradiation and acute small bowel toxicity was supported by the use of both small bowel loop and peritoneal space contouring techniques. Receiver operating characteristic analysis demonstrated that, for both contouring methods, the greatest sensitivity for predicting toxicity was associated with the volume receiving between 15 and 25 Gy. Conclusion: DVH analysis of peritoneal space volumes accurately predicts grade ≥3 small bowel toxicity in patients with rectal cancer receiving neoadjuvant chemoradiation therapy, suggesting that the contours of the peritoneal space provide a reasonable surrogate for the contours of individual small bowel loops. The study finds that a small bowel V15 less than 275 cc and a peritoneal space V15 less than 830 cc are associated with a less than 10% risk of grade ≥3 acute toxicity

2006-01-01

Purpose: We sought to investigate retrospectively the safety and effectiveness of using external hand compression to displace adjacent bowel loops during MRI-guided percutaneous cryoablation of renal tumors. Materials and methods: Fourteen patients (six women, eight men; mean age: 72 years) with 15 renal tumors (mean diameter: 2.4 cm; range: 1.4-4.6 cm) adjacent to bowel were treated with MRI-guided percutaneous cryoablation during which bowel was displaced manually. Bowel loop of concern was ascending colon (n 5), descending colon (n = 8), descending colon and small bowel (n = 1), ascending colon and small bowel (n = 1). To analyze effectiveness of the maneuver, mean distance between tumor margin and bowel before and after the maneuver were compared and analyzed using paired Student's t-test. Minimum distance between iceball edge and adjacent bowel with external manual displacement during freezing was also measured. Safety was assessed by analyzing post-procedural MR imaging for adjacent bowel wall thickening and focal fluid collections as well as patients' clinical and imaging follow-up. Results: Mean distance between tumor margin and closest adjacent bowel increased from 0.8 cm (range: 0-2 cm) before external manual compression to 2.6 cm (range: 1.6-4.1 cm) with manual displacement (p < 0.01). Mean minimum distance between iceball edge and closest adjacent bowel during the procedures was 1.6 cm (range: 0.5-3.5 cm). No evidence of bowel injury was encountered. Twelve of 15 tumors had follow-up (mean: 10 months) that showed no tumor recurrence. Conclusion: MRI-guided percutaneous cryoablation of renal tumors adjacent to bowel can be done safely and effectively using external hand compression to displace bowel loops

Prin, C.

2012-01-01

Between 2004 and 2006, EDF noticed primary / secondary leakages on Steam Generators (SG) of a French nuclear plant. Further studies have shown that fouling by iron oxides and clogging of the quatrefoils broached holes of the Tubes Support Plates (TSP) are aggravating factors of the risk of cracking by vibration-induced fatigue of the SG's tubes. EDF then initiated a program of chemical cleaning of steam generators to restore and maintain an acceptable state of cleanliness of the secondary part of SG. This paper presents EDF's strategy to achieve this goal. It is organized as follows : first, fouling and clogging phenomenon and associated estimation means are explained. Then the strategy of chemical cleaning and its evolution are presented. The implemented processes as well as process monitoring and plants requalification are also described. Finally, the operations performed, the continuous improvement process conducted in connection with the French Nuclear Safety Authority (ASN) and the control of environmental impact are reviewed. This paper was written with the support of AREVA and Westinghouse, the two operators of chemical cleaning in France. (author)

One of the perceived disadvantages of the biliopancreatic diversion with duodenal switch operation is diarrhea. The aim of this study was to compare the bowel habits of patients after duodenal switch operation or Roux-en-Y gastric bypass. A prospective comparative case series design was used. Forty-six patients who underwent duodenal switch (n=28) or gastric bypass (n=18) were asked to complete a daily diary for 14 days after losing least 50% of their excess body weight. Data were collected on number of bowel episodes, incontinence, urgency, stool consistency, and awakening from sleep to defecate. Background variables were recorded from the medical files. The duodenal switch group was heavier (body mass index 53.5 vs 47.0 kg/m(2), p=0.03) and older (47.5 vs 41.0 years, p=NS) than the gastric bypass group. Median time to 50% excess body weight loss was 22 months in the duodenal switch group compared to 10.0 months in the gastric bypass group (p=0.001). Patients after duodenal switch surgery reported a median of 23.5 bowel episodes over the 14-day study period compared to 16.5 in the gastric bypass group (p=NS). There was no between-group differences in any of the other bowel parameters studied. Although duodenal switch is associated with more bowel episodes than gastric bypass, the difference is not statistically significant. Bowel habits are similar in patients who achieve 50% estimated body weight loss with duodenal switch surgery or gastric bypass.

Full Text Available Context The term inflammatory bowel disease (IBD classically includes ulcerative colitis (UC and Crohn’s disease (CD. An abnormally increased mucosal permeability seems to underlie UC, whereas CD is thought to be the result of an immune deficiency state. Evidence Acquisition While these phenomena may well be labeled as genetic factors, the environment has its role as well. Drugs (chiefly, antibiotics and non-steroidal anti-inflammatory molecules, with proton pump inhibitors recently joining the list and smoking habits are all being scrutinized as IBD causative factors. Results Once almost unknown, the prevalence of IBD, in the Eastern World and China, is now increasing by manifold, therefore arousing warning signals. Conclusions A multidisciplinary approach will soon be necessary, to face the tenacious behavior of IBD, on a global perspective.

To define functional gastrointestinal pain, irritable bowel syndrome (IBS), levator ani syndrome, proctalgia fugax, the pathophysiology of these syndromes and the treatments that can be proposed. Review of articles published on the theme based on a Medline (PubMed) search and consensus conferences selected according to their scientific relevance. IBS is very common. Patients report abdominal pain and/or discomfort, bloating, and abnormal bowel habit (diarrhoea, constipation or both), in the absence of any structural or biochemical abnormalities. IBS has a complex, multifactorial pathophysiology, involving biological and psychosocial interactions resulting in dysregulation of the brain-gut axis associated with disorders of intestinal motility, hyperalgesia, immune disorders and disorders of the intestinal bacterial microflora and autonomic and hormonal dysfunction. Many treatments have been proposed, ranging from diet to pharmacology and psychotherapy. Patients with various types of chronic pelvic and perineal pain, especially those seen in urology departments, very often report associated IBS. This syndrome is also part of a global and integrated concept of pelviperineal dysfunction, avoiding a rigorous distinction between the posterior segment and the midline and anterior segments of the perineum.

Enteroclysis and small bowel series: Comparison of radiation dose and examination time

International Nuclear Information System (INIS)

Thoeni, R.F.; Gould, R.G.

1991-01-01

Respective radiation doses and total examination and fluoroscopy times were compared for 50 patients; 25 underwent enteroclysis and 25 underwent small bowel series with (n = 17) and without (n = 8) an examination of the upper gastrointestinal (GI) tract. For enteroclysis, the mean skin entry radiation dose (12.3 rad [123 mGy]) and mean fluoroscopy time (18.4 minutes) were almost 1 1/2 times greater than those for the small bowel series with examination of the upper GI tract (8.4 rad [84 mGy]; 11.4 minutes) and almost three times greater than those for the small bowel series without upper GI examination (4.6 rad [46 mGy]; 6.3 minutes). However, the mean total examination completion time for enteroclysis (31.2 minutes) was almost half that of the small bowel series without upper GI examination (57.5 minutes) and almost four times shorter than that of the small bowel series with upper GI examination (114 minutes). The higher radiation dose of enteroclysis should be considered along with the short examination time, the age and clinical condition of the patient, and the reported higher accuracy when deciding on the appropriate radiographic examination of the small bowel

Acute bowel ischemia (ABT) is a life-threatening condition which most often effects elderly patients. It requires an intensive treatment and quick diagnosis. Unfortunately ABI manifested not only by specific but also various nonspecific clinical or laboratory finding. The radiological symptoms of the bowel ischemia are also differentiated and often nonspecific while the specific findings are rather uncommon.That is why the knowledge of the bowel ischemia pathogenesis and possible CT findings is so important for the correct diagnosis. The our paper, we present the radiological findings of the acute bowel ischemia based on the analysis of the patients' abdominal -CT examination. The purpose of our study is to MDCT in patients with acute bowel ischemia. The material of this study consists of four computer tomography examinations - three of those an angio-CT and one abdominal - in patients with acute abdomen symptoms. The result revealed the mesenteric thrombosis in two cases, and mesenteric artery stenosis in one case. In one case, the thrombus was present in the abdominal aorta. In conclusion, we claim that the MDCT should be the modality of choice for the diagnosis of the acute bowel ischemia. (author)

Power, N.; Atri, M.; Ryan, S.; Haddad, R.; Smith, A.

2007-01-01

Aim: To evaluate the predictors of clinically important gastrointestinal anastomotic leaks using multidetector computed tomography (CT). Subjects and methods: Ninety-nine patients, 73 with clinical suspicion of anastomotic bowel leak and 26 non-bowel surgery controls underwent CT to investigate postoperative sepsis. Fifty patients had undergone large bowel and 23 small bowel anastomoses. The time interval from surgery was 3-30 days (mean 10 ± 5.9 SD) for the anastomotic group and 3-40 days (mean 14 ± 11 SD) for the control group (p = 0.3). Two radiologists blinded to the final results reviewed the CT examinations in consensus and recorded the presence of peri-anastomotic air, fluid or combination of the two; distant loculated fluid or combination of fluid and air; free air or fluid; and intestinal contrast leak. Final diagnosis of clinically important anastomotic leak (CIAL) was confirmed at surgery or by chart review of predetermined clinical and laboratory criteria. Results: The prevalence of CIAL in the group undergoing CT was 31.5% (23/73). The CT examinations with documented leak were performed 5-28 (mean; 11.4 ± 6 SD) days after surgery. Nine patients required repeat operation, 10 percutaneous abscess drainage, two percutaneous drainage followed by surgery, and two prolonged antibiotic treatment and total parenteral nutrition (TPN). Of the CT features examined, only peri-anastomotic loculated fluid containing air was more frequently seen in the CIAL group as opposed to the no leak group (p = 0.04). There was no intestinal contrast leakage in this cohort. Free air was present up to 9 days and loculated air up to 26 days without CIAL. Conclusion: Most postoperative CT features overlap between patients with and without CIAL. The only feature seen statistically more frequently with CIAL is peri-anastomotic loculated fluid containing air

THE AIM OF THE STUDY was sonographic assessment of the gallbladder and its contractility in functional abdominal pain and irritable bowel syndrome in children. The study comprised 96 children aged 6 to 18 years, 59 girls and 37 boys. Depending on diagnosis, the children were divided into three groups. 38 children with functional abdominal pain constituted the first group, 26 children with irritable bowel syndrome were included to the second group, the third group consisted of 32 healthy children (control group). Diagnosis of functional abdominal pain and irritable bowel syndrome was made based on the III Rome Criteria. In irritable bowel syndrome both forms with diarrhea (13) and with constipation (13) were observed. Anatomy and contractility of the gallbladder were assessed by ultrasound examination. The presence of septum, wall thickness, thick bile, vesicle volume in fasting state and 30th and 60th minute after test meal were taken into consideration. Test meal comprised about 15% of caloric requirement of moderate metabolism. Children with bile stones and organic diseases were excluded from the study. Thickened vesicle wall and thick bile were present more frequently in children with irritable bowel syndrome and functional abdominal pain than in control group (p functional abdominal pain than in irritable bowel syndrome and control group (p = 0.003, p = 0.05). Vesicle contractility after test meal was greatest in children with functional abdominal pain. Evaluation of diminished (smaller than 30%) and enlarged (greater then 80%) gallbladder contractility at 30th and 60th minute after test meal demonstrated disturbances of contractility in children with irritable bowel syndrome and functional abdominal pain.

Full Text Available Accidental ingestion of foreign bodies are a common condition in clinical practice. However, small bowel perforation which dues to ingestion foreign bodies has been rarely seen. In this article, we report a case of small bowel perforation which dues to ingestion foreign body. A 80-year-old female patient, presenting with complaints of acute abdomen, was admitted to the emergency department. She denied abdominal pain, nausea and vomiting. The patient had tenderness and defense on the right lower quadrant. Contrast enhanced abdominal computed tomography has been used on the patient's diagnosis. This revealed small bowel perforation due to the ingestion of foreign body. The patient was operated emergency. A microperforation due to fish bone was detected on the terminal ileum. The patient underwent debridement and primary repair. The patient was discharged postoperative 7th day without problem. Bowel perforation due to the ingestion of foreign bodies should be considered in the differential diagnosis of acute abdomen. Keywords: Foreign body, Small intestine, Perforation

Capsule endoscopy was approved by the FDA in 2001. Gastrointestinal bleeding and inflammatory bowel disease are the main indications. It has been available in our hospital since 2004. We retrospectively analysed data from patients who underwent small bowel capsule endoscopy in our hospital from October 2004 to April 2015. Indications were divided into: Obscure gastrointestinal bleeding (occult and overt), inflammatory bowel disease, and other indications. Findings were divided into: Vascular lesions, inflammatory lesions, other lesions, normal studies, and inconclusive studies. A total of 1027 out of 1291 small bowel studies were included. Mean patient age was 56.45 years; 471 were men and 556 women. The most common lesion observed was angiectasia, as an isolated finding or associated with other lesions. Findings were significant in up to 80% of studies when the indication was gastrointestinal bleeding, but in only 50% of studies in inflammatory bowel disease. Diagnostic yield was low in the group «other indications». No major complications were reported. Small bowel capsule endoscopy has high diagnostic yield in patients with gastrointestinal bleeding, but yield is lower in patients with inflammatory bowel disease. Our experience shows that capsule endoscopy is a safe and useful tool for the diagnosis of small bowel disease. The diagnostic yield of the technique in inflammatory bowel disease must be improved.

Objective: To evaluate influence of prone/ supine position, gender, operation, bladder distension on bowel irradiated for patients with rectal cancer during pelvic radiotherapy. Methods: 36 patients with rectal cancer were investigated. Treatment plans were created with three dimensional treatment planning system. The dose and volume of bowel irradiated were analyzed according to dose-volume histograms (DVH) for every patient. The prescribed dose was 50 Gy. Results: The extent of bladder distension significantly influenced the mean doses and the V 45 high dose volumes of bowel irradiated. The treatment position and gender significantly influenced the V 15 low dose volume of bowel irradiated, the operation significantly influenced the mean doses of bowel. Either prone and supine position, or preoperative and postoperative, the doses of bowel irradiated for good bladder distension were lower and the volumes were smaller than that for bad bladder distension. The V 45 high dose volume of bowel irradiated for bad and good bladder distension at prone position were 15.3% and 7.4% (P=0.023), respectively, and at postoperative 14.1% and 7.2% (P=0.014), respectively. Conclusions: The doses and volumes of pelvic bowel irradiated were significantly influenced by the extent of bladder distension, and partly influenced by the prone/supine position, gender and operation.

Gastrointestinal Motility, Part 2: Small-Bowel and Colon Transit.

Science.gov (United States)

Maurer, Alan H

2016-03-01

Because of the difficulty often encountered in deciding whether a patient's symptoms originate in the upper or lower gastrointestinal tract, gastrointestinal transit scintigraphy is a uniquely suited noninvasive, quantitative, and physiologic method of determining whether there is a motility disorder affecting the stomach, small bowel, or colon. Small-bowel and colon transit studies can be performed alone or together with gastric emptying studies after oral administration of an appropriately radiolabeled meal. It is hoped that newly published standards for performing these studies and the anticipated arrival of new Current Procedural Terminology codes in the United States for small-bowel and colon transit studies will increase their availability and use. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

Magnetic reasonance (MR) enterography enables high contrast resolution depiction of the location and cause of bowel obstruction through a combination of predictable luminal distension and multiplanar imaging capabilities. Furthermore, because the patient is not exposed to ionizing radiation, sequential 'dynamic' MR imaging can be performed repeatedly over time further facilitating depiction of the site and/or the cause of obstruction. With increasing availability of MR imaging and standardization of the oral contrast medium regimens, it is likely that this technique will assume an ever-increasing role in the evaluation of small bowel dilation in the coming years. We illustrate the utility of MR enterography in the evaluation of small bowel dilation, whether it be mechanical, functional (e.g., ileus), or related to infiltrative mural disease.

To study graft-versus-host reaction (GVHR) in small-bowel transplantation and its underlying mechanisms and to find methods for circumventing GVHR, we used an unidirectional GVHR model in which F1 Lewis (LEW) x Wistar King A (WKA) hybrid rats received small-bowel transplants from either LEW or WKA parent rats. The survival time of F1 hybrid rats that received full-length small-bowel transplantation from LEW and WKA was 16.3+/-2.1 days and 18.2+/-3.4 days, respectively. When one-quarter of LEW small bowel was transplanted to an F1 hybrid recipient, the survival time was significantly longer at 44.0+/-23.4 days compared with rats that had received full-length LEW small-bowel transplantation. The survival time of F1 hybrid rats which received an injection of high-dose (5 x 10(8) cells) LEW or WKA spleen cells was 11.9+/-4.0 days and 13.1+/-3.6 days, respectively. However, when an injection containing a low dose (1 x 108 cells) of LEW spleen cells was used, survival was > 100 days, showing significance compared with the survival of rats receiving the higher dose LEW spleen-cell injection. Both small-bowel transplantation and spleen-cell injection were compared for the effective period of recipient resistance to donor cell or small-bowel transplantation as second challenge. When the F1 rats given a quarter LEW small-bowel transplant as first challenge were treated with a high-dose of spleen cells 30 days after transplantation, they survived for > 30 days without GVHR. F1 rats that were treated with a low-dose LEW spleen-cell injection, followed 30 days later by full LEW small-bowel transplantation, had a survival time of > 100 days. These results indicate that segmental small-bowel transplantation and spleen-cell injection as first challenge may facilitate the prevention of GVHR, resulting in resistance to subsequent immunological challenge.

1980-01-01

A group of patients with damage of the GI tract by therapeutic irradiation for intra-abdominal neoplasma such as the carcinoma of uterus and rectum has been presented. With regard to the location of radiation damage, 32 cases of them are limited in the recto-sigmoid colon, 3 cases in the small bowel and 4 cases in both bowels. Among 19 cases who underwent an operation, radiation damage was found in the colon of 12 cases. Colostomy was made in all cases and in 2 cases colon resection was also performed. If radiation damage is noticed only in the rectum, colostomy is good indicated except for the cases in which a massive bleeding is seen. As to small bowel damages, if the symptoms of patient do not respond to the conservative treatment, operative intervention is necessary. At operation, the surgeon should be aware of the risks involved in performing adhesiolysis. (author)

Phytobezoar in a jejunal diverticulum as a cause of small bowel obstruction: a case report

Directory of Open Access Journals (Sweden)

Rauf Fozia

2011-09-01

Full Text Available Abstract Introduction Phytobezoars are concretions of poorly digested fruit and vegetable fibers found in the alimentary tract. Previous gastric resection, gastrojejunostomy, or pyloroplasty predispose people to bezoar formation. Small-bowel bezoars normally come from the stomach, and primary small-bowel bezoars are very rare. They are seen only in patients with underlying small-bowel diseases such as diverticula, strictures, or tumors. Primary small-bowel bezoars almost always present as intestinal obstructions, although it is a very rare cause, being responsible for less than 3% of all small-bowel obstructions in one series. Jejunal diverticula are rare, with an incidence of less than 0.5%. They are usually asymptomatic pseudodiverticula of pulsion type, and complications are reported in 10% to 30% of patients. A phytobezoar in a jejunal diverticulum is an extremely rare presentation. Case presentation A 78-year-old Pakistani man presented to our clinic with small-bowel obstruction. Upon exploration, we found a primary small-bowel bezoar originating in a jejunal diverticulum and causing jejunal obstruction. Resection and anastomosis of the jejunal segment harboring the diverticulum was performed, and our patient had an uneventful recovery. Conclusion Primary small-bowel bezoars are very rare but must be kept in mind as a possible cause of small-bowel obstruction.

Full Text Available Background. Functional dyspepsia is the prototype functional gastrointestinal disorder. This study was designed to determine its prevalence, subtypes, and risk factors associated with the subtypes. Method. Patients with upper gastrointestinal symptoms who presented for endoscopy were administered a questionnaire containing the functional dyspepsia and irritable bowel syndrome modules of the Rome III diagnostic criteria. Results. Of 192 patients who had functional dyspepsia, epigastric pain syndrome, postprandial distress syndrome, and combination of the two subtypes accounted for 79.2%, 62.5%, and 50%, respectively. Multivariate analysis of the risk factors showed that independent predictors of postprandial distress syndrome were alcohol and irritable bowel syndrome while irritable bowel syndrome was independent predictor of epigastric pain syndrome. Alcohol, smoking, and use of nonsteroidal anti-inflammatory drugs were independent predictors of cooccurrence of postprandial distress syndrome and epigastric pain syndrome. Conclusion. Functional dyspepsia accounts for 62.5% of dyspepsia in a population of black African patients. Regarding symptomatology, epigastric pain syndrome, postprandial distress syndrome, and combination of the two subtypes account for 79.2%, 62.5%, and 50%, respectively. Risk factors for functional dyspepsia are irritable bowel syndrome, alcohol, smoking, and use of nonsteroidal anti-inflammatory drugs.

Full Text Available Objective: To evaluate if addition of educational cartoon to pediatric bowel preparation instructions improves the quality of bowel preparation and patient experience. Methods: Patients were randomized to control group receiving standard bowel preparation instructions or intervention group receiving additional educational cartoon. To objectively rate bowel preparation, a blinded endoscopist completed numeric Ottawa score (0-14, with 0 being best. The family also completed a questionnaire rating the bowel preparation process. Results: Data from 23 patients were analyzed. Mean Ottawa score in the intervention group compared with controls was not significantly different (mean scores 3.73 and 3.33, respectively; P = .384. Level of education was significantly correlated with better Ottawa score in the overall population (ρ = −.462, P = .026 and within the control group (ρ = −.658, P = .02. Both groups of patients reported positive experience with bowel preparation. Conclusion: There may be benefit to further investigation of this educational cartoon in parents with less than college level education or non-English-speaking families in larger population of patients.

Inadequate bowel preparation is a problem frequently encountered by gastroenterologists who perform colonoscopies on hospitalized patients. A method is needed to increase the quality of bowel preparation in inpatients. An educational booklet has been shown to increase the overall quality of bowel preparation for outpatients. We performed a prospective study to evaluate the effects of an educational booklet on the quality of bowel preparation in a group of hospitalized patients. We performed a randomized, single-blind, controlled trial of all inpatients at a tertiary care medical center scheduled for inpatient colonoscopy from October 2013 through March 2014. They were randomly assigned to groups that were (n = 45) or were not (controls, n = 40) given the booklet before bowel preparation the evening before their colonoscopy. All patients received a standard bowel preparation (clear liquid diet the day before the procedure, followed by split-dose GoLYTELY). At the colonoscopy, the Boston Bowel preparation scale (BBPS) was used to assess bowel preparation. The primary outcome measure was adequate bowel preparation (a total BBPS score ≥6 with all segment scores ≥2). Secondary outcomes assessed included total BBPS score, BBPS segment score, and a total BBPS score of 0. There were no differences between the groups in age, race, sex, body mass index, history of colonoscopy, history of polyps, or time of colonoscopy. Twenty-eight patients who received the booklet (62%) and 14 who did not (35%) had an adequate bowel preparation (P = .012). The number needed to treat to attain adequate bowel preparation was 4. After adjusting for age and history of prior colonoscopies, the odds of achieving an adequate bowel preparation and a higher total BBPS score after receipt of the booklet were 3.14 (95% confidence interval, 1.29-7.83) and 2.27 (95% confidence interval, 1.05-4.88), respectively. Three patients in the booklet group and 9 in the no-booklet group had a BBPS score

Learning disability nurses have a key role in addressing the health inequalities experienced by people with learning disabilities. People with learning disabilities are less likely to participate in bowel screening than other sectors of the population, despite there being evidence of this population being at an increased risk of developing bowel cancer. There are a range of barriers at individual and systemic levels that impact on participation in bowel screening by people with learning disabilities. Actions to address these barriers have been identified in the literature and learning disability nurses are a key agent of change in enabling people with learning disabilities to participate in the national screening programmes.

Full Text Available The growth rate of inflammatory bowel diseases among children actualizes early detection of this pathology form and its aftera effects, including secondary osteoporosis. The research purpose is to study the characteristics of osseous tissue mineralization, disorder of physical growth and sexual maturity of children, suffering from inflammatory bowel diseases. The researchers have examined 116 children, including 33 children, suffering from inflammatory bowel diseases; 26 children, suffering from persistent colitis; 29 children, suffering from gasatroduodenitis; and 28 children with no GI tract pathologies. The study deals with estimate of level of mineral osseous tissue density, biochemical rates of osseous metabolism, as well as physical growth and sexual maturity. reduction of mineral osseous tissue density was found among 48,5% of children, suffering from inflammatory bowel diseases, 23% of children, suffering from persistent colitis, 31% of children, suffering from chronic gastritis and 18% of almost healthy children, at the same time, it was more apparent among children, suffering from inflammatory bowel diseases. The lowest rates of mineral osseous tissue density were among girls. Calcium phosphoric metabolism did not change apart from calcium creatinine coefficient, if osteopenia was observed. Thus, reduction of mineral osseous tissue density is often observed among children, suffering from inflammatory bowel diseases, especially among adolescent girls. Therefore, it conditions the necessity to include densimetry into the conventional examination plan for children, suffering from inflammatory bowel diseases. Authors also find it advisable to monitor physical growth and sexual maturity of children.Key words: children, inflammatory bowel diseases, osteoporosis.

Rational Use of Antibiotics in the Treatment of Functional Bowel Disorders

Directory of Open Access Journals (Sweden)

Roberta Fasulo

2010-07-01

Full Text Available Functional gastrointestinal symptoms such us bloating, fullness, flatulence, diarrhea, and constipation due to irritable bowel syndrome (IBS were recently attributed to small bowel bacterial overgrowth, a condition depending on the presence of an increased number of bacteria in the small bowel. However, the methodology used to describe this association may be harshly criticized, since it has already been shown to be quite inaccurate. As a result an inappropriate use of antibiotics was consequently generated. In fact, antibiotics could be effective in the treatment of functional complaints, but only in a limited subgroup of patients, characterized by an increase of fermentation at colonic level. In this review, we have examined the papers suggesting a pathophysiological link between IBS and small bowel bacterial overgrowth, underlining its inappropriateness, and put forth our personal view on the rationale for antibiotic use in IBS.

To evaluate rational and experiential intelligence in irritable bowel syndrome (IBS) sufferers. We recruited 100 subjects with IBS as per Rome II criteria (50 consulters and 50 non-consulters) and 100 healthy controls, matched by age, sex and educational level. Cases and controls completed a clinical questionnaire (including symptom characteristics and medical consultation) and the following tests: rational-intelligence (Wechsler Adult Intelligence Scale, 3rd edition); experiential-intelligence (Constructive Thinking Inventory); personality (NEO personality inventory); psychopathology (MMPI-2), anxiety (state-trait anxiety inventory) and life events (social readjustment rating scale). Analysis of variance was used to compare the test results of IBS-sufferers and controls, and a logistic regression model was then constructed and adjusted for age, sex and educational level to evaluate any possible association with IBS. No differences were found between IBS cases and controls in terms of IQ (102.0 +/- 10.8 vs 102.8 +/- 12.6), but IBS sufferers scored significantly lower in global constructive thinking (43.7 +/- 9.4 vs 49.6 +/- 9.7). In the logistic regression model, global constructive thinking score was independently linked to suffering from IBS [OR 0.92 (0.87-0.97)], without significant OR for total IQ. IBS subjects do not show lower rational intelligence than controls, but lower experiential intelligence is nevertheless associated with IBS.

Instructional videos on bowel preparation have been shown to improve bowel preparation scores during colonoscopy. YouTube™ is one of the most frequently visited website on the internet and contains videos on bowel preparation. In an era where patients are increasingly turning to social media for guidance on their health, the content of these videos merits further investigation. We assessed the content of bowel preparation videos available on YouTube™ to determine the proportion of YouTube™ videos on bowel preparation that are high-content videos and the characteristics of these videos. YouTube™ videos were assessed for the following content: (1) definition of bowel preparation, (2) importance of bowel preparation, (3) instructions on home medications, (4) name of bowel cleansing agent (BCA), (5) instructions on when to start taking BCA, (6) instructions on volume and frequency of BCA intake, (7) diet instructions, (8) instructions on fluid intake, (9) adverse events associated with BCA, and (10) rectal effluent. Each content parameter was given 1 point for a total of 10 points. Videos with ≥5 points were considered by our group to be high-content videos. Videos with ≤4 points were considered low-content videos. Forty-nine (59 %) videos were low-content videos while 34 (41 %) were high-content videos. There was no association between number of views, number of comments, thumbs up, thumbs down or engagement score, and videos deemed high-content. Multiple regression analysis revealed bowel preparation videos on YouTube™ with length >4 minutes and non-patient authorship to be associated with high-content videos.

Role of antibiotics for treatment of inflammatory bowel disease.

Inflammatory bowel disease is thought to be caused by an aberrant immune response to gut bacteria in a genetically susceptible host. The gut microbiota plays an important role in the pathogenesis and complications of the two main inflammatory bowel diseases: Crohn's disease (CD) and ulcerative colitis. Alterations in gut microbiota, and specifically reduced intestinal microbial diversity, have been found to be associated with chronic gut inflammation in these disorders. Specific bacterial pathogens, such as virulent Escherichia coli strains, Bacteroides spp, and Mycobacterium avium subspecies paratuberculosis, have been linked to the pathogenesis of inflammatory bowel disease. Antibiotics may influence the course of these diseases by decreasing concentrations of bacteria in the gut lumen and altering the composition of intestinal microbiota. Different antibiotics, including ciprofloxacin, metronidazole, the combination of both, rifaximin, and anti-tuberculous regimens have been evaluated in clinical trials for the treatment of inflammatory bowel disease. For the treatment of active luminal CD, antibiotics may have a modest effect in decreasing disease activity and achieving remission, and are more effective in patients with disease involving the colon. Rifamixin, a non absorbable rifamycin has shown promising results. Treatment of suppurative complications of CD such as abscesses and fistulas, includes drainage and antibiotic therapy, most often ciprofloxacin, metronidazole, or a combination of both. Antibiotics might also play a role in maintenance of remission and prevention of post operative recurrence of CD. Data is more sparse for ulcerative colitis, and mostly consists of small trials evaluating ciprofloxacin, metronidazole and rifaximin. Most trials did not show a benefit for the treatment of active ulcerative colitis with antibiotics, though 2 meta-analyses concluded that antibiotic therapy is associated with a modest improvement in clinical symptoms

Irritable bowel syndrome: the burden and unmet needs in Europe.

LENUS (Irish Health Repository)

Quigley, E M M

2012-02-03

Irritable bowel syndrome affects approximately 10-15% of the European population, although prevalence rates vary depending on the classification used and the country surveyed. This may be due to differences in patterns of medical care and diagnosis of the condition. Up to 70% of individuals with irritable bowel syndrome may not have been formally diagnosed. The disorder affects 1.5-3 times as many women as men and poses a significant economic burden in Europe, estimated at euro 700-euro 1600 per person per year. It also reduces quality of life and is associated with psychological distress, disturbed work and sleep, and sexual dysfunction. It is a chronic disorder, which affects many individuals for more than 10 years. Most patients are managed in primary care, although some are referred to gastroenterologists and other specialists. Patients with irritable bowel syndrome undergo more abdomino-pelvic surgery than the general population. We propose that a positive diagnosis of the condition may avoid the delay in diagnosis many patients experience. We conclude that, in Europe, there are significant unmet needs including lack of familiarity with irritable bowel syndrome, difficulties in diagnosis and lack of effective treatments for the multiple symptoms of the disorder. The development of pan-European guidelines for irritable bowel syndrome will benefit patients with this condition in Europe.

Place of phosphatidylcholine in the treatment of inflammatory bowel disease

Full Text Available In the pathogenesis of most diseases of the intestine, inflammation is important, and, often, critical. Its pathogenetic role in the inflammatory bowel disease was studied broadly and comprehensively. In recent years, research has begun on its contribution to intestinal damage in functional pathology — irritable bowel syndrome. The participation of inflammation in the development of erosive and ulcerative lesions of the lower gastrointestinal tract on the background of non-steroidal anti-inflammatory drugs (NSAID-enterocolopathy seems paradoxical. The role of phospholipids in the construction of cell membranes is well known. One of the main membrane phospholipids of most living organisms (with the exception of microbes is phosphatidylcholine (PC. In membranes of the intestinal epithelium, the content of PC increases from 10 to 50 % in the direction from the apical surface to the basal one, and the maximum amount of PC is located on the outside of the cell membranes. Phosphatidylcholine showed its high efficacy and safety in the treatment of inflammatory bowel diseases, such as non-specific ulcerative colitis. People taking NSAIDs have demonstrated the protective role of PC in preventing damage to the upper and lower gastrointestinal tract. Given the common pathogenetic mechanisms between these diseases and irritable bowel syndrome, the use of PC in patients with irritable bowel syndrome seems promising, especially in its post-infection variant.

Fetal primary small bowel volvulus without atresia or malrotation is an extremely rare but life-threatening surgical emergency. We report a case of primary small bowel volvulus that presented as sudden fetal distress and was diagnosed on the basis of the 'whirl-pool sign' of fetal sonography. This diagnosis led to emergency operation after birth at the third trimester with a good outcome. Although the pathogenesis of fetal primary small bowel volvulus is unclear, ganglion cell immaturity may play a role in the etiology. Copyright © 2013 Elsevier Inc. All rights reserved.

Torigian, Drew A.; Levine, Marc S.; Rubesin, Stephen E.; Laufer, Igor

2001-01-01

Objective: The purpose of this study was to assess the frequency of isolated small bowel dilatation on abdominal radiographs in patients with colonic fecal impaction and also to elucidate the cause of this finding. Methods: A computerized search of radiology files revealed 515 patients with colonic fecal impaction on abdominal radiographs. The radiologic reports described isolated small bowel dilatation not related to other known causes of ileus or obstruction in 18 (3.5%) of the 515 patients. The films were reviewed to determine the distribution of fecal impaction and the degree and extent of small bowel dilatation. In 16 cases, medical records were reviewed to determine the clinical presentation, treatment, and course. Finally, follow-up radiographs were reviewed in four cases to determine the response to treatment of the impaction. Results: All 16 patients with available medical records had abdominal symptoms. The average diameter of the dilated small bowel on abdominal radiographs was 3.7 cm. Fourteen patients (78%) had a diffuse colonic fecal impaction (nine) or a predominantly right-sided fecal impaction (five) that involved the cecum, and the remaining four (22%) had a left-sided colonic fecal impaction. All 12 patients with clinical follow-up had resolution of symptoms and all four with follow-up radiographs had resolution of small bowel dilatation after treatment of the underlying impaction. Conclusion: Fecal impaction should be considered in the differential diagnosis of small bowel dilatation on abdominal radiographs, as treatment of the underlying impaction usually produces a dramatic clinical response with resolution of the small bowel dilatation on follow-up radiographs

Diospyrobezoar as a Cause of Small Bowel Obstruction

2012-09-01

Full Text Available Phytobezoar, a concretion of indigestible fibers derived from ingested vegetables and fruits, is the most common type of bezoar. Diospyrobezoar is a subtype of phytobezoar formed after excessive intake of persimmons (Diospyros kaki. We report the case of a diabetic man with a 5-day history of abdominal pain after massive ingestion of persimmons who developed signs of complicated small bowel obstruction. The patient had a previous history of Billroth II hemigastrectomy associated with truncal vagotomy to treat a chronic duodenal ulcer 14 years earlier. Since intestinal obstruction was suspected, he underwent emergency laparotomy that revealed an ileal obstruction with small bowel perforation and local peritonitis due to a phytobezoar that was impacted 15 cm above the ileocecal valve. After segmental intestinal resection, the patient had a good recovery and was discharged on the 6th postoperative day. This report provides evidence that diospyrobezoar should be considered as a possible cause of small bowel obstruction in patients who have previously undergone gastric surgery.

High-quality bowel preparation is necessary for colonoscopy. A few studies have been conducted to investigate improvement in bowel preparation quality through patient education. However, the effect of patient education on bowel preparation has not been well studied. A randomized and prospective study was conducted. All patients received regular instruction for bowel preparation during a pre-colonoscopy visit. Those scheduled for colonoscopy were randomly assigned to view an educational video instruction (video group) on the day before the colonoscopy, or to a non-video (control) group. Qualities of bowel preparation using the Ottawa Bowel Preparation Quality scale (Ottawa score) were compared between the video and non-video groups. In addition, factors associated with poor bowel preparation were investigated. A total of 502 patients were randomized, 250 to the video group and 252 to the non-video group. The video group exhibited better bowel preparation (mean Ottawa total score: 3.03 ± 1.9) than the non-video group (4.21 ± 1.9; P educational video could improve the quality of bowel preparation in comparison with standard preparation method.

Bär, Florian; Sina, Christian; Fellermann, Klaus

2013-01-01

Although a great variety of new drugs have been introduced for the therapy of inflammatory bowel diseases so far, a definite cure of the disease is still out of scope. An anti-inflammatory approach to induce remission followed by maintenance therapy with immunosupressants is still the mainstay of therapy. Thiopurines comprising azathioprine and its active metabolite mercaptopurine as well as tioguanine, are widely used in the therapy of chronic active inflammatory bowel disease (IBD). Their steroid sparing potential and efficacy in remission maintenance are out of doubt. Unfortunately, untoward adverse events are frequently observed and may preclude further administration or be life threatening. This review will focus on new aspects of thiopurine therapy in IBD, its efficacy and safety. PMID:23555158

Nutrigenetics, nutrigenomics and inflammatory bowel diseases.

Ferguson, Lynnette R

2013-08-01

Inflammatory bowel disease includes ulcerative colitis and Crohn's disease, which are both inflammatory disorders of the gastrointestinal tract. Both types of inflammatory bowel disease have a complex etiology, resulting from a genetically determined susceptibility interacting with environmental factors, including the diet and gut microbiota. Genome Wide Association Studies have implicated more than 160 single-nucleotide polymorphisms in disease susceptibility. Consideration of the different pathways suggested to be involved implies that specific dietary interventions are likely to be appropriate, dependent upon the nature of the genes involved. Epigenetics and the gut microbiota are also responsive to dietary interventions. Nutrigenetics may lead to personalized nutrition for disease prevention and treatment, while nutrigenomics may help to understand the nature of the disease and individual response to nutrients.

Coffee enemas are believed to cause dilatation of bile ducts and excretion of bile through the colon wall. Proponents of coffee enemas claim that the cafestol palmitate in coffee enhances the activity of glutathione S-transferase, an enzyme that stimulates bile excretion. During video capsule endoscopy (VCE), excreted bile is one of the causes of poor preparation of the small bowel. This study aimed to evaluate the feasibility and effect of coffee enema for preparation of the small bowel during VCE. In this pilot study, 17 of 34 patients were assigned to the coffee enema plus polyethylene glycol (PEG) 2 L ingestion group, whereas the 17 remaining control patients received 2 L of PEG only. The quality of bowel preparation was evaluated in the two patient groups. Bowel preparations in the proximal segments of small bowel were not differ between two groups. In the mid and distal segments of the small intestine, bowel preparations tend to be better in patients who received coffee enemas plus PEG than in patients who received PEG only. The coffee enema group did not experience any complications or side effects. Coffee enemas may be a feasible option, and there were no clinically significant adverse events related to coffee enemas. More prospective randomized studies are warranted to improve small bowel preparation for VCE. PMID:25136541

Scintigraphic pattern of small bowel bleeding

Anshu Rajnish Sharma; Charan, S.; Silva, I.

2004-01-01

Introduction: Small intestine is the longest part of gastrointestinal tract. Intra-luminal haemorrhage occurring anywhere in its long and tortuous course is difficult to trace. It is relatively inaccessible to endoscopic evaluation. Upper GI endoscopy can see only up to distal duodenum, whereas colonoscope can view maximum of 30 centimeters of terminal ileum after negotiating the scope through ileo-caecal valve. Hence, localization of bleeding source from small bowel remains a difficult clinical problem. This group of patients can be evaluated with scintigraphy for localizing the site of bleeding before undergoing either angiography or surgery. To our best of knowledge, there is no study, which has utilized scintigraphy for evaluation of small bowel bleed exclusively. The present study has been designed to know the efficacy of 99mTc-RBC scintigraphy in detecting small bowel bleed and to know whether it can differentiate between jejunal and ileal bleeding ? Materials and methods: Thirteen patients presenting with lower gastrointestinal bleeding (malena) were enrolled for the study. In all cases, upper GI endoscopy (UGIE) was unremarkable. Colonoscopic examination was either negative or suspected bleeding occurring proximal to ileo-caecal valve. Thus, in these patients, it is presumed clinically that bleeding is originating from small bowel. Barium meal follow through (BMFT) studies, however, could not delineate any etiological lesion in these patients. There were 8 men and 5 women (mean age 48 years). All patients were anemic (Hb- 6 gm%) and mean 3 units of blood were transfused.These patients were subjected to Tc-99m labeled red blood cells scintigraphy (15 mci, in-vivo method) for localization of source of bleeding. The scintiscan was acquired in two phases. A first pass phase acquired at a rate of 2 seconds per frame for 60 seconds followed by acquisition of static abdominal images (500 K, 256 x 256 matrix) at 5 minutes intervals up to 90 minutes on LFOV gamma

2015-01-01

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder which is characterised by symptoms such as bloating, altered bowel habit and visceral pain. It’s generally accepted that miscommunication between the brain and gut underlies the changes in motility, absorpto-secretory function and pain sensitivity associated with IBS. However, partly due to the lack of disease-defining biomarkers, understanding the aetiology of this complex and multifactorial disease remains elusi...

2014-01-01

Full Text Available Background. Uterine leiomyosarcoma is a rare and aggressive gynecologic malignancy with an overall poor prognosis. Lungs, bones, and brain are common sites of metastases of uterine leiomyosarcoma. Metastases of uterine leiomyosarcoma to the small bowel are extremely rare, and only four case reports have been published to date. Case presentation. A 55-year-old Saudi woman diagnosed with a case of uterine leiomyosarcoma treated with total abdominal hysterectomy (TAH and bilateral salpingooophorectomy (BSO presented in emergency room after sixteen months with acute abdomen. Subsequent work-up showed a jejunal mass for which resection and end-to-end anastomosis were performed. Biopsy confirmed the diagnosis of small bowel metastasis from uterine leiomyosarcoma. Further staging work-up showed wide spread metastasis in lungs and brain. After palliative cranial irradiation, systemic chemotherapy based on single agent doxorubicin was started. Conclusion. Metastatic leiomyosarcoma of small bowel from uterine leiomyosarcoma is a rare entity and is sign of advanced disease. It should be differentiated from primary leiomyosarcoma of small bowel as both are treated with different systemic chemotherapeutic agents.

AN ANALYTICAL STUDY IN ADHESIVE BOWEL OBSTRUCTION

Directory of Open Access Journals (Sweden)

Gerald Anand Raja

2017-04-01

Full Text Available BACKGROUND Peritoneal adhesions can be defined as abnormal fibrous bands between organs or tissues or both in the abdominal cavity that are normally separated. Adhesions may be acquired or congenital; however, most are acquired as a result of peritoneal injury, the most common cause of which is abdominopelvic surgery. Less commonly, adhesions may form as the result of inflammatory conditions, intraperitoneal infection or abdominal trauma. The extent of adhesion formation varies from one patient to another and is most dependent on the type and magnitude of surgery performed as well as whether any postoperative complications develop. Fortunately, most patients with adhesions do not experience any overt clinical symptoms. For others, adhesions may lead to any one of a host of problems and can be the cause of significant morbidity and mortality. MATERIALS AND METHODS This is a retrospective study of 50 patients admitted in Government Royapettah Hospital with adhesive bowel obstruction between September 2008 to September 2010. All patients were admitted and managed either conservatively or surgically. RESULTS 1. Adhesive bowel disease is the most common cause for bowel obstruction followed by hernias. 2. Increased incidence is noted in females. 3. Increased incidence of adhesions was documented in gynaecological and colorectal surgeries. 4. Below umbilical incisions have higher propensity for adhesion formation. 5. Laparotomies done for infective aetiology have higher adhesion risks. 6. Most of adhesive obstructions can be managed conservatively. 7. Adhesiolysis preferably laparoscopic can be done. For gangrenous bowel resection and anastomosis or ostomy done. 8. Given the above risk factors, adhesive bowel disease can be prevented to a certain extent. CONCLUSION The formation of peritoneal adhesions continues to plague patients, surgeons and society. Although, research in this area is ongoing, there is currently no method that is 100% effective in

Full Text Available Mr. P was a 57-year-old man who presented with symptoms of bowel obstruction in the setting of a known metastatic pancreatic cancer. Diagnosis of malignant bowel obstruction was made clinically and radiologically and he was treated conservatively (non-operativelywith octreotide, metoclopromide and dexamethasone, which provided good control over symptoms and allowed him to have quality time with family until he died few weeks later with liver failure. Bowel obstruction in patients with abdominal malignancy requires careful assessment. The patient and family should always be involved in decision making. The ultimate goals of palliative care (symptom management, quality of life and dignity of death should never be forgotten during decision making for any patient.

Adenosine A2B Receptors: An Optional Target for the Management of Irritable Bowel Syndrome with Diarrhea?

Directory of Open Access Journals (Sweden)

Teita Asano

2017-11-01

Full Text Available Irritable bowel syndrome (IBS is a functional gastrointestinal disorder, with the characteristic symptoms of chronic abdominal pain and altered bowel habits (diarrhea, constipation, or both. IBS is a highly prevalent condition, which negatively affects quality of life and is a significant burden on global healthcare costs. Although many pharmacological medicines have been proposed to treat IBS, including those targeting receptors, channels, and chemical mediators related to visceral hypersensitivity, successful pharmacotherapy for the disease has not been established. Visceral hypersensitivity plays an important role in IBS pathogenesis. Immune activation is observed in diarrhea-predominant patients with IBS and contributes to the development of visceral hypersensitivity. Adenosine is a chemical mediator that regulates many physiological processes, including inflammation and nociception. Among its receptors, the adenosine A2B receptor regulates intestinal secretion, motor function, and the immune response. We recently demonstrated that the adenosine A2B receptor is involved in visceral hypersensitivity in animal models of IBS. In this review, we discuss the possibility of the adenosine A2B receptor as a novel therapeutic target for IBS.

We evaluated 40 patients with strangulated bowel obstructions who underwent surgery at our hospital between September 2000 and August 2005. Here, the patients' background characteristics, cause of strangulation, clinical symptoms, laboratory and imaging results, preoperative diagnosis, treatment and prognosis are discussed. The sex ratio was 1:1, the average age was 71.2 years, and 31 cases (77.5%) had past histories of abdominal surgery, mainly in the lower abdominal region. As for the causes of the constrictions, adhesions and funiculi accounted for half of the cases. We recognized 23 cases (57.5%) because of peritoneal irritation signs and 8 cases (20.0%) because of a state of shock; both groups underwent emergency operations. Regarding imaging findings, abdominal computed tomography revealed ascites in 28 cases (77.8%) and limited bowel dilation in 25 cases (69.4%) the correct preoperative diagnosis rate was 85.0%. Bowel resections were performed in 29 cases (72.5%). Five patients (12.5%) died, three because of multiple organ failure and two because of respiratory insufficiency (i.e., pneumonia). Patients with a poor general condition or severe complications must be adequately cared for, although the diagnosis of this disease is comparatively easy. (author)

Enterocolic lymphocytic phlebitis: statistical analysis of histology features in viable and ischemic bowel.

Science.gov (United States)

Medlicott, Shaun A C; Guggisberg, Kelly A; DesCôteaux, Jean-Gaston; Beck, Paul

2006-07-01

Enterocolic lymphocytic phlebitis is a rare cause of segmental ischemic enterocolitis. This artery-sparing transmural vasculitis is classically a circumferential phlebitis with perivenular lymphocyte cuffing and thrombi in the absence of systemic manifestations. Myointimal hyperplasia may represent a chronic phase of enterocolic lymphocytic phlebitis. Subclinical or early stage enterocolic lymphocytic phlebitis is not well delineated. We analyzed 600 submucosal and subserosal veins from both ischemic and intact bowel segments to discern if vascular morphology varied between sites. Crescentic and circumferential lymphocytic phlebitis is more common in viable bowel than in the ischemic segment. A nonsignificant trend was found for increased crescentic morphology between intact bowel remote from the ischemic focus compared with that adjacent to the ischemic focus. Hallmarks of ischemic bowel are necrotizing phlebitis and thrombi formation. Thrombophlebitis morphology is distinctly different in viable and ischemic bowel, changing from the classic lymphocytic to necrotizing lesions respectively.

Occult spondyloarthritis in inflammatory bowel disease.

2016-02-01

Spondyloarthritis (SpA) is a frequent extra-intestinal manifestation in patients with inflammatory bowel disease (IBD), although its real diffusion is commonly considered underestimated. Abnormalities in the microbioma and genetic predisposition have been implicated in the link between bowel and joint inflammation. Otherwise, up to date, pathogenetic mechanisms are still largely unknown and the exact influence of the bowel activity on rheumatic manifestations is not clearly explained. Due to evidence-based results of clinical studies, the interest on clinically asymptomatic SpA in IBD patients increased in the last few years. Actually, occult enthesitis and sacroiliitis are discovered in high percentages of IBD patients by different imaging techniques, mainly enthesis ultrasound (US) and sacroiliac joint X-ray examinations. Several diagnostic approaches and biomarkers have been proposed in an attempt to correctly classify and diagnose clinically occult joint manifestations and to define clusters of risk for patient screening, although definitive results are still lacking. The correct recognition of occult SpA in IBD requires an integrated multidisciplinary approach in order to identify common diagnostic and therapeutic strategies. The use of inexpensive and rapid imaging techniques, such as US and X-ray, should be routinely included in daily clinical practice and trials to correctly evaluate occult SpA, thus preventing future disability and worsening of quality of life in IBD patients.

Gastrointestinal angiodysplasias recurrently bleed, accounting for 3-5% of obscure gastrointestinal bleeding. The advent of small bowel capsule endoscopy (SBCE) has led to an increased recognition of small bowel angiodysplasias (SBAs) but little is known about their etiology. Previous small cohorts and case reports suggest an equal gender incidence and associations with cardiovascular disease, renal impairment, and coagulopathies.

Does surgery for deep infiltrating bowel endometriosis improve fertility? A systematic review.

Iversen, Maja L; Seyer-Hansen, Mikkel; Forman, Axel

2017-06-01

Reduced fertility is a major concern in women with endometriosis. The influence of surgery of deep infiltrating endometriosis (DIE) affecting the bowel wall on fertility is controversial and the literature on this field is heterogeneous. In this review we addressed whether surgery for bowel DIE improves the spontaneous pregnancy rate, and the results of in vitro fertilization (IVF), and the potential risk of such surgery. We conducted a literature search including the terms "deep", "deep infiltrating", "bowel", rectovaginal", "endometriosis", "fertility", "infertility" and "IVF" in PubMed. No randomized controlled studies were found. Other publications of relevance included four retrospective and three prospective observational studies. Moreover, one retrospective study compared results of IVF treatment with or without previous surgery for bowel DIE. All studies reported detailed data on surgical complications. The poor data quality precluded firm conclusions. The results indicate, however, the possibility that surgery for bowel DIE may improve the spontaneous pregnancy rate, and positive effects on IVF outcome cannot be excluded. Such surgery will be associated with risk of major complications. The lack of proper data precludes conclusions on the potential role for bowel DIE surgery to improve the spontaneous pregnancy rate and results of IVF treatment. Positive effects cannot be excluded, but the definite risk of major complications must be taken into account. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Appointment waiting times and education level influence the quality of bowel preparation in adult patients undergoing colonoscopy

Full Text Available Abstract Background Risk factors for poor bowel preparation are recognized to be independent of the type of bowel preparation method used. Patient and administrative factors influencing bowel preparation are known to vary in different healthcare systems. Methods A prospective, cross-sectional study of patients undergoing colonoscopy in an Asian tertiary centre was conducted to identify risk factors associated with poor bowel preparation, and to evaluate the impact of poor bowel preparation on technical performance and patient comfort. Results Data on 501 patients (mean age 60.1 ± 14.0 years old, 51.2% males, 60.9% with secondary education or higher was available for analysis. Poor bowel preparation was present in 151 patients (30.1%. Lower education level (OR = 2.35, 95% CI = 1.54 - 3.60, colonoscopy appointment waiting time beyond 16 weeks (OR = 1.86, 95% CI = 1.04 - 3.37 and non-adherence to bowel preparation instructions (OR = 4.76, 95% CI = 3.00 - 7.55 were identified as independent risk factors for poor bowel preparation. Poor bowel preparation was associated with a lower cecal intubation rate (78.1% versus 98.3%, p Conclusions Education levels and appointment waiting times, in addition to non-adherence to bowel preparation instructions, increase the risk of poor bowel preparation in adult patients undergoing colonoscopy. The latter has a significant impact on colonoscopy performance and patient comfort.

Computed tomography features of small bowel volvulus

Small bowel volvulus is a cause of acute abdomen and commonly occurs in neonates and young infants. Although it is rare in adults in the Western world,' it is a relatively common surgical emergency in the Middle East, India and Central Africa. It is associated with a mortality rate of 10-67% and, hence, it is important to make an early diagnosis to expedite surgical intervention. Computed tomography has become an important imaging modality in diagnosis and a number of signs have been recognized in a handful of documented case reports. We describe a case of small bowel volvulus that illustrates these important CT signs. Copyright (1999) Blackwell Science Pty Ltd

Use of Prebiotics for Inflammatory Bowel Disease

Andrew Szilagyi

2005-01-01

Full Text Available The relevance of diet in both the pathogenesis and the therapy of inflammatory bowel disease is an evolving science. Disturbance of intestinal microflora (dysbiosis is putatively a key element in the environmental component causing inflammatory bowel disease. Prebiotics are among the dietary components used in an attempt to counteract dysbiosis. Such predominantly carbohydrate dietary components exert effects on the luminal environment by physicochemical changes through pH alteration, by production of short chain fatty acids and by selectively promoting putatively 'health-beneficial' bacteria. The present review elaborates on some of the background rationale and mechanisms on the use of prebiotics. Additionally, published animal and human trials are discussed.

How Probiotic Reduce Symptoms of Irritable Bowel Syndrome?

2014-04-01

Full Text Available Introduction: Irritable bowel syndrome (IBS is a common gastrointestinal disorder in children that may lead to anxiety, frequent physician visits and school absenteeism. The aim of this study is to reviewe effects of probiotic for irritable bowel syndrome.   Materials and Methods: This study review articles about probiotic for irritable bowel syndrome in pubmed and google scholar.   Results: Multiple etiologic factors were suggested for IBS, including psychosocial factors, altered gastrointestinal motility,   malfermentation of food residues and changes in the intestinal micro flora. It is reported that patients with IBS have a great homogeneity in the fecal flora with a decrease in lactobacilli, coliforms and bifidobacteria in comparison to healthy individuals. The beneficial effects of probiotics in IBS could be explained by increasing the mass of beneficial bacteria such as lactobacilli strains in the digestive tract, decreasing bacterial overgrowth in the small bowel. Recently it was also demonstrated that some lactobacilli strains may modulate intestinal pain attacks by inducing the expression of μ-opioid and cannabinoid receptors in the intestinal epithelial cells. Probiotics can also reinforce the intestinal mucosal barrier and normalize the motility of the digestive tract and its visceral sensitivity and reversing the imbalance between the pro- and anti-inflammatory cytokines so that suggested as a therapeutic option for IBS.   Conclusion: Probiotic has been suggested as a therapeutic option for IBS by modulation pathophysiologic events in these patients.

Christoffer Soendergaard

2017-05-01

Full Text Available Growth hormone (GH plays major anabolic and catabolic roles in the body and is important for regulating several aspects of growth. During an inflammatory process, cells may develop a state of GH resistance during which their response to GH stimulation is limited. In this review, we will emphasize specific mechanisms governing the formation of GH resistance in the active phase of inflammatory bowel disease. The specific molecular effects mediated through individual inflammatory mediators and processes will be highlighted to provide an overview of the transcriptional, translational and post-translational inflammation-mediated impacts on the GH receptor (GHR along with the impacts on GH-induced intracellular signaling. We also will review GH’s effects on mucosal healing and immune cells in the context of experimental colitis, human inflammatory bowel disease and in patients with short bowel syndrome.

Small bowel diverticulitis is a rare cause of an acute abdomen. Originating from acquired diverticula of the jejunum, less often of the ileum, or Meckel diverticulum, the symptoms are non-specific, simulating other acute inflammatory disorders, such as appendicitis, cholecystitis or colonic diverticulitis. The diagnosis of small bowel diverticulitis is solely based on radiologic findings, with computed tomography (CT) regarded as the method of choice. In recent years, a number of case reports have described the spectrum of the CT features in acute small bowel diverticulitis and its dependence on the severity of the inflammatory process. Typical findings are an inflamed diverticulum, inflammatory mesenteric infiltration, extraluminal gas collection and mural edema of adjacent small bowel loops with resultant separation of bowel loops. An enterolith is rarely found in an inflamed diverticulum. Complications include abscesses, fistulae, small bowel obstruction and free perforation with peritonitis. Small bowel diverticulitis can be a diagnostic problem if it involves the terminal ileum or Meckel's diverticulum. For preoperative confirmation of the presumed diagnosis of small bowel diverticulitis on CT, an enteroclysis for acquired diverticula or a technetium scan for Meckel's diverticulum should be performed. We present the CT findings in three patients of acute small bowel diverticulitis, two affecting the jejunum and one a Meckel's diverticulum. (orig.)

Purpose: Hyperfractionation has been advocated to improve local tumor control by increasing radiation dose without increasing late normal tissue complications. The aim of this study was to determine if hyperfractionation decreased late bowel complications. Methods and Materials: Thirty patients with Stage II and III cervical cancer were randomized to receive either hyperfractionation or conventional fractionation. Patients were followed for 5 years and monitored for tumor control, recurrence, and bowel complications. The relative risks of tumor control and bowel complications were computed at 1 year and 5 years of follow-up. Kaplan-Meier survival curves were plotted to determine probabilities of being tumor-free and bowel complication-free. Results: There were 15 patients in each group. At 1 year of follow-up, 2 patients in the hyperfractionation group (13%) and 7 patients in the conventional treatment group (45%) had tumor (relative risk [RR] 0.3; 95% confidence interval [CI] 0.1, 1.1; p = 0.054). Delayed bowel complications were seen in 8 patients in the hyperfractionation group and 1 patient in the conventional treatment group (RR 7.5; 95% CI 1.1, 52; p = 0.014). At 5 years, 2 patients in the hyperfractionation group and 8 patients in the conventional treatment group had tumor (RR 0.3; 95% CI 0.1, 1.1; p = 0.04). Delayed bowel complications (Grades 2 and 3) occurred in 9 women in the hyperfractionation group and 2 patients in the conventional group (RR 5.4; 95% CI 1.5, 19.5; p 0.0006). Kaplan-Meier analysis showed that the hyperfractionation group had significantly more bowel complications over the 5 years of follow-up (p 0.024). Conclusion: Hyperfractionation may result in better tumor control both at 1 year and at 5 years following treatment of cervical cancer. However, hyperfractionation could lead to increased late bowel complications and must be used judiciously in the treatment of cervical cancer

Full Text Available Abstract Background Despite a lower incidence of bowel cancer overall, Indigenous Australians are more likely to be diagnosed at an advanced stage when prognosis is poor. Bowel cancer screening is an effective means of reducing incidence and mortality from bowel cancer through early identification and prompt treatment. In 2006, Australia began rolling out a population-based National Bowel Cancer Screening Program (NBCSP using the Faecal Occult Blood Test. Initial evaluation of the program revealed substantial disparities in bowel cancer screening uptake with Indigenous Australians significantly less likely to participate in screening than the non-Indigenous population. This paper critically reviews characteristics of the program which may contribute to the discrepancy in screening uptake, and includes an analysis of organisational, structural, and socio-cultural barriers that play a part in the poorer participation of Indigenous and other disadvantaged and minority groups. Methods A search was undertaken of peer-reviewed journal articles, government reports, and other grey literature using electronic databases and citation snowballing. Articles were critically evaluated for relevance to themes that addressed the research questions. Results The NBCSP is not reaching many Indigenous Australians in the target group, with factors contributing to sub-optimal participation including how participants are selected, the way the screening kit is distributed, the nature of the test and comprehensiveness of its contents, cultural perceptions of cancer and prevailing low levels of knowledge and awareness of bowel cancer and the importance of screening. Conclusions Our findings suggest that the population-based approach to implementing bowel cancer screening to the Australian population unintentionally excludes vulnerable minorities, particularly Indigenous and other culturally and linguistically diverse groups. This potentially contributes to exacerbating

Epstein-Barr virus infection is associated with inflammatory bowel disease, but its role as a pathogenetic or exacerbating factor remains unclear. The aim of this study was to evaluate the association between Epstein-Barr virus infection and inflammatory bowel disease, particularly in regard to exacerbation of disease activity. This was a nonrandomized crosssectional study in subgroups of patients with inflammatory bowel disease compared with a control group with noninflammatory disease. Participants were patients treated for ulcerative colitis or Crohn's disease and individuals undergoing evaluation for noninflammatory disease recruited from 2 urban adult gastrointestinal referral centers in Greece. Diagnosis of inflammatory bowel disease was based on standard clinical and endoscopic criteria. Demographic and clinical characteristics of all participants were recorded. Whole blood samples and fresh tissue samples from biopsy of intestinal sites were obtained from each participant. The presence of Epstein-Barr virus was determined by amplifying the LMP1 gene of the virus in blood and intestinal tissue samples. The study comprised 94 patients with inflammatory bowel disease (63 with ulcerative colitis and 31 with Crohn's disease) and 45 controls with noninflammatory disease. Of the 94 patients, 67 (71.3%) had disease exacerbation and 27 (28.7%) were in remission. The prevalence of Epstein-Barr virus genome was significantly higher in patients than in controls for intestinal tissue (44 patients, 46.8% vs 6 controls, 13.3%; p = 0.001), but not for whole blood (24 patients, 25.5% vs 9 controls, 20%; p = 0.3). The viral genome was found significantly more frequently in intestinal samples from patients with disease exacerbation compared with patients in remission (38 patients with exacerbation, 56.7% vs 6 patients in remission, 22.2%; p = 0.001), but no significant difference was found for whole blood (18 patients with exacerbation, 26.8% vs 6 patients in remission, 22

The interrelationships between ventilation rate, indoor air quality, and energy consumption in operation rooms at rest are yet to be understood. We investigate the effect of ventilation rate on indoor air quality indices and energy consumption in ORs at rest. The study investigates the air temperature, relative humidity, concentrations of carbon dioxide, particulate matter (PM), and airborne bacteria at different ventilation rates in operation rooms at rest of a medical center. The energy consumption and cost analysis of the heating, ventilating, and air conditioning (HVAC) system in the operation rooms at rest were also evaluated for all ventilation rates. No air-conditioned operation rooms had very highest PM and airborne bacterial concentrations in the operation areas. The bacterial concentration in the operation areas with 6-30 air changes per hour (ACH) was below the suggested level set by the United Kingdom (UK) for an empty operation room. A 70% of reduction in annual energy cost by reducing the ventilation rate from 30 to 6 ACH was found in the operation rooms at rest. Maintenance of operation rooms at ventilation rate of 6 ACH could save considerable amounts of energy and achieve the goal of air cleanliness.

Inflammatory bowel diseases, principally Crohn's disease and ulcerative colitis, and celiac disease are among the most common immune-mediated gastrointestinal diseases. We aim to elucidate the clinical course and outcomes of patients with concomitant inflammatory bowel disease and celiac disease, a unique population that remains scarcely studied to date. A retrospective matched case-control study of adults with coexistent inflammatory bowel disease and celiac disease was performed at a tertiary referral institution in North America. Logistic regression and Kaplan-Meier curves compared disease characteristics and clinical outcomes of the two groups. A total of 342 inflammatory bowel disease patients were included in this study, of which 114 had coexistent celiac disease and 228 did not. Patients with coexistent inflammatory bowel disease and celiac disease had higher rates of primary sclerosing cholangitis (19.3% vs 5.7%; odds ratio, 4.4; 95% confidence interval, 2.1-9.4; pceliac disease (10.5% vs 3.5%; odds ratio 3.2; 95% confidence interval 1.3-8.2; p=0.01), compared to patients without concomitant celiac disease. Patients with inflammatory bowel disease with concomitant celiac disease have unique phenotypic features compared to non-celiac inflammatory bowel disease, with higher risks for colitis-related hospitalizations, extensive colitis, and primary sclerosing cholangitis. Increased recognition of coexistent IBD and celiac disease can prompt clinicians to investigate for concomitant disease sooner, particularly in patients with seemingly refractory disease.

Digestive volvulus affects the stomach, small bowel and mobile segments of the colon and often has a developmental cause. Reference radiologic examinations include upper gastrointestinal contrast series for gastric volvulus, possibly with ultrasonography for small-bowel volvulus, and contrast enema for colonic volvulus. Treatment is usually surgical. This pictorial essay describes the embryological development and discusses the clinical and radiologic presentation of volvulus, depending on location, and details the appropriate radiologic examinations.

Full Text Available The aim of our study was to compare patients with irritable bowel syndrome (IBS and healthy controls regarding the expression of toll-like receptors 2, 4, 5, and 9 (TLR2, TLR4, TLR5, and TLR9, the primary mucosal receptors of bacterial components, in small and large bowel mucosa. Methods. We analysed biopsies from jejunum and sigmoid colon of 22 patients (17 females with IBS aged 18–66 (median: 39 years and 14 healthy volunteers (12 females aged 22–61 (median: 42 years. Eight patients had constipation-predominant IBS (C-IBS, 7 had diarrhoea-predominant IBS (D-IBS, and 7 had IBS without predominance of constipation or diarrhoea. We analysed mRNA levels for TLRs using quantitative PCR and distribution of TLRs in mucosa using immunohistochemistry. Results. We found increased mRNA expression of TLR4 (mean fold change 1.85±0.31 versus 1.0±0.20; p<0.05, TLR5 (1.96±0.36 versus 1.0±0.20; p<0.05 and TLR9 (2.00±0.24 versus 1.0±0.25; p<0.01 but not of TLR2 in the small bowel mucosa from patients with IBS compared to the controls. There was no significant difference in mRNA levels for TLRs in colon mucosa between patients and controls. Conclusion. Upregulation of TLR4, TLR5, and TLR9 suggests the involvement of bacteria or dysregulation of the immune response to commensal flora in small bowel mucosa in IBS patients.

Full Text Available The incidence of chronic diarrhea in Asia is between 0.8-1.0%. The diseases and abnormalities according to the location, which can cause chronic diarrhea, are divided into three locations: the small bowel, the large bowel and extraintestinal. The small bowel diseases include infectious and non-infectious diseases. The infectious diseases are bacterial infections, parasitic infections etc. The non-infectious diseases include of Crohn’s disease, Celiac sprue, NSAID enteropathy, lactose intolerance, benign tumor, carcinoid tumor, carcinoma, post surgery complications, laxative etc. The approaches to diagnosis include good anamnesis, careful physical examination, supporting laboratory tests, more specialized supporting examinations including X-ray of the colon, esophagogastroduodenum follow-through, enteroclysis, ileo-colonoscopy and endoscopy on the upper portion of the digestive tract including the small intestine with biopsy for histopathology examinations. The treatment for chronic diarrhea is divided into supportive and causal therapy. (Med J Indones 2002; 11: 179-89 Keywords: small bowel, chronic diarrhea, approaches to diagnosis, treatment

Comorbid Illness, Bowel Preparation, and Logistical Constraints Are Key Reasons for Outpatient Colonoscopy Nonattendance

2016-01-01

Full Text Available Background. Colonoscopy nonattendance is a challenge for outpatient clinics globally. Absenteeism results in a potential delay in disease diagnosis and loss of hospital resources. This study aims to determine reasons for colonoscopy nonattendance from a Canadian perspective. Design. Demographic data, reasons for nonattendance, and patient suggestions for improving compliance were elicited from 49 out of 144 eligible study participants via telephone questionnaire. The 49 nonattenders were compared to age and sex matched controls for several potential contributing factors. Results. Nonattendance rates were significantly higher in winter months; the OR of nonattendance was 5.2 (95% CI, 1.6 to 17.0, p<0.001 in winter versus other months. Being married was positively associated with attendance. There was no significant association between nonattendance and any of the other variables examined. The top 3 reasons for nonattendance were being too unwell to attend the procedure, being unable to complete bowel preparation, or experiencing logistical challenges. Conclusions. Colonoscopy attendance rates appear to vary significantly by season and it may be beneficial to book more colonoscopies in the summer or overbook in the winter. Targets for intervention include more tailored teaching sessions, reminders, taxi chits, and developing a hospital specific colonoscopy video regarding procedure and bowel preparation requirements.

In a patient who underwent surgical excision of recurrent tumor of ovarian disgerminoma, small bowel injury following radiotherapy was treated by extensive excision of the small intestine followed by intravenous hyperalimentation (I.V.H.) and hyperbaric oxygen therapy. From its clinical course and treatment, we concluded that 1) In small bowel complication due to radiation injury, especially perforation of the small bowel, radical excision of the diseased segment is most promising, if the general and local conditions permit. 2) I.V.H. is effective for protecting and improving postoperative malnutrition after extensive excision of the small bowel. 3) Hyperbaric oxygen therapy is very effective for postoperative paralytic ileus in the case in which surgical operation cannot be performed. 4) Zinc deficiency as a complication of prolonged I.V.H. therapy must be protected. 5) It is necessary to study pathophysiology of short bowel syndrome following the extensive excision and to continue treatment and careful long-term follow-up.

Buhmann, S.; Wielage, C.; Fischer, T.; Reiser, M.; Lienemann, A.; Kirchhoff, C.; Mussack, T.

2005-01-01

Purpose: to develop and evaluate a method to visualize and quantify large bowel motility using functional cine MRI. Methods: fifteen healthy individuals (8males, 7 females, 20 to 45 years old) with no history or present symptoms of bowel disorders were enrolled in a functional cine MRI examination at 6 a. m. after a starving phase for at least eight hours before and after oral administration of Senna tea (mild stimulating purgative). Two consecutive sets of repeated measurements of the entire abdomen were performed using a 1.5T MRI system with coronal T2-weighted HASTE sequences anatomically adjusted to the course of the large bowel. A navigator technique was used for respiratory gating at the level of the right dorsal diaphragm. The changes in diameter (given in cm) were measured at 5 different locations of the ascending (AC), transverse (TC) and descending colon (DC), and assessed as parameters for the bowel motility. Results: the mean values as a statistical measure for large bowel relaxation were determined. Before ingestion of Senna tea, the mean diameter measured 3.41 cm (ascending colon), 3 cm (transverse colon) and 2.67 cm (descending colon). After the ingestion of Senna tea, the mean diameter increased to 3.69 cm (ascending colon) to 3.4 cm (transverse colon) and to 2.9 cm (descending colon). A statistically significant difference was demonstrated with the Wilcoxon test (level of confidence 0.05). For the determination of dynamic increase, the changes of the statistical scatter amplitude to the mean value were expressed as percentage before and after the ingestion of Senna tea. Thereby, an increase in variation and dynamic range was detected for the AC (112.9%) and DC (100%), but a decrease in the dynamics for the TC (69%). Conclusion: a non-invasive method for the assessment of bowel motility was developed for the first time. The use of functional cine MRI utilizing a prokinetic stimulus allowed visualisation and quantification of large bowel motility

The primary objective was to explore young people's risk appraisals of bowel cancer, including whether they had a coherent understanding of the protective effects of physical activity (PA). A secondary objective was to examine whether the illness risk representations (IRRs) framework could be used to understand beliefs underlying bowel cancer risk appraisals. Qualitative. Framework analysis of semi-structured interviews with 19 people aged 14-17 years. Participants judged their risk of getting bowel cancer as low. This was based on a lack of family history of cancer and their current lifestyle behaviours, which were viewed as having a protective effect, or because they planned on making change to their lifestyle in the future when disease risk became more relevant. Participants were not aware of, and struggled to understand, the link between PA and bowel cancer. They also lacked knowledge of the effects of, or treatments for, bowel cancer. Beliefs underlying judgements about the risk of bowel cancer fitted the IRR framework reasonably well. The present research suggests that interventions designed to increase PA with a view to reducing the risk of bowel cancer should aim to make the future risk of bowel cancer feel more tangible, help young people to understand the full range of consequences, explain how and why preventative behaviours such as PA are effective in reducing risk, and emphasize that the typical late presentation of symptoms, and therefore investigation by health care services, reduces treatability. Statement of contribution What is already known on this subject? Physical activity (PA) performed throughout the lifespan can have a protective effect on bowel cancer, but levels of PA are low among young people. Changing beliefs about the risk of getting bowel cancer may be a useful strategy in motivating PA. What does this study add? Increased understanding of how young people think about bowel cancer and the relationship between PA and cancer

Inflammatory bowel disease is a chronic, debilitating disorder of the gastrointestinal tract. The etiology of inflammatory bowel disease has not been elucidated, but is thought to be multifactorial with both environmental and genetic influences. A large body of research has been conducted to elucidate the etiology of inflammatory bowel disease. This article reviews this literature, emphasizing the studies of breastfeeding and the studies of genetic factors, particularly NOD2 polymorphisms.

Hepatoid adenocarcinoma is a rare extrahepatic tumor defined as having a morphologic and immunohistochemical similarity to hepatocellular carcinoma. In this case report, we describe a patient with hepatoid adenocarcinoma of the jejunum with multiple liver metastases that developed in the absence of risk factors. We describe the radiologic findings including those of dynamic computed tomography and small bowel follow-through. To the best of our knowledge, only two cases of hepatoid adenocarcinoma of the small bowel have been reported in patients with inflammatory bowel disease.

Small bowel volvulus in children. Its appearance on the barium enema examination

1980-01-01

Two children with small bowel volvulus diagnosed on barium enema examination are reported. In one patient the volvulus was associated with malrotation and in the other patient there was a post-operative peritoneal adhesion. In both cases the diagnosis was based on beaking of the head of the barium column at the site of volvulus. Radiographic demonstration of a beak sign in the small bowel on barium enema examination should suggest a diagnosis of small bowel volvulus, and indicates the need for immediate surgery.

1995-01-01

This experimental study was performed for evaluate the effects of cis-diamminedichloroplatinum(II) (cis-DDP) on the radiation injury of rat bowel by histopathologic changes. Rats were exposed to entire abdomen by a single doses of X-ray(6-10 Gy) without or with cis-DDP(2.5mg/kg). Rats were divided into 3 groups such as radiation alone, cis-DDP alone and combined group. In combined group, cis-DDP was given 30 minutes before or immediately after irradiation. Cis-DDP induced the inflammatory cell infiltrations with focal necrosis of the mucosa in the small bowel and no abnormal change in the large bowel. In radiation alone group, mucosal necrosis, submucosal fibrosis and muscular necrosis were prominent changes in small bowel and submucosal fibrosis in the large bowel. The submucosal fibrosis in the small bowel was appeared in 10 Gy of radiation alone group and 8 Gy of cis-DDP infusion after radiation and 6 Gy of cis-DDP infusion before radiation of combined group. In the large bowel, submucosal fibrosis was noted in 8 Gy of radiation alone group 8 Gy of cis-DDP infusion after radiation and 6 Gy of cis-DDP infusion before radiation of combined group. In the small bowel, the enhancement ratio was 1.67 in a group of cis-DDP infusion before radiation and 1.25 in group of cis-DDP infusion after radiation as the end point was the submucosal fibrosis. In the large bowel, the enhancement ratio was 1.33 in a group of cis-DDP infusion before radiation and 1.0 in a group of cis-DDP infusion after radiation as the end point was the submucosal fibrosis. This study suggested that cis-DDP enhance the radiation effect in the small and large bowel especially when cis-DDP was infused before radiation

There is no consensus concerning small bowel preparation before capsule endoscopy (CE). This study evaluated the effects of 4 regimens on small bowel cleansing and diagnostic yield. Patients were randomly divided into 4 groups. Group A consumed a clear liquid diet after lunch on the day before CE, followed by overnight fasting. Group B took 250 mL 20% mannitol and 1 L 0.9% saline orally at 05:00 hours on the day of the procedure. In group C, the same regimen was taken at 20:00 hours on the day before and at 05:00 hours on the day of CE. In group D, in addition to the group C regimen, 20 mL oral simethicone was taken 30 minutes before CE. Two hundred patients were prospectively enrolled, and 7 were excluded from the final analysis because of incomplete small bowel transit. No significant difference was noted among the 4 groups for small bowel transit time. Bowel preparation in group D was significantly better than for the other regimens for overall cleansing of the proximal small bowel, and showed improved overall cleansing of the distal small bowel when compared with 10-hours overnight fasting. Pathological lesions of the proximal and distal small bowel were, respectively, achieved in 82 and 74 patients, mostly distributed in group D. Small bowel preparation that involves split-dose oral mannitol plus single-dose simethicone for CE can improve mucosal visualization and subsequent diagnostic yield when compared with 10-hours overnight fasting.

Abdominal tuberculosis (TB) is the sixth most common extrapulmonary site of involvement. The sites of involvement in abdominal tuberculosis, in descending order of frequency, are lymph nodes, genitourinary tract, peritoneal cavity, and gastrointestinal tract. The radiological armamentarium for evaluating tuberculosis of the small bowel (SBTB) includes barium studies (small bowel follow-through, SBFT), CT (multidetector CT, CT enterography, and CT enteroclysis), ultrasound (sonoenteroclysis), and magnetic resonance imaging (MRI; enterography and enteroclysis). In this review, we illustrate the abnormalities at MDCT enterography in 20 consecutive patients with SB TB and also describe extraluminal findings in these patients. MDCT enterography allows non-invasive good-quality assessment of well-distended bowel loops and the adjacent soft tissues. It displays the thickness and enhancement of the entire bowel wall in all three planes and allows examination of all bowel loops, especially the ileal loops, which are mostly superimposed. The terminal ileum and ileocaecal junction are the most common sites of small bowel involvement in intestinal TB. The most common abnormality is short-segment strictures with symmetrical concentric mural thickening and homogeneous mural enhancement. Other findings include lymphadenopathy, ascites, enteroliths, peritoneal thickening, and enhancement. In conclusion, MDCT enterography is a comprehensive technique for the evaluation of SB TB

1985-01-01

The physiology, solution composition, indications, efficacy, and safety of whole-bowel irrigation (WBI) for mechanical bowel cleansing are reviewed. WBI with isotonic electrolyte solutions produces diarrhea when the infusion rate exceeds the capacity of the intestine to distend and absorb the solution. A number of solutions are used for WBI, including 0.9% sodium chloride, balanced electrolyte solutions, lactated Ringer's, mannitol, and electrolyte solutions containing polyethylene glycol 3350 (PEG). WBI solution administration rates vary from 15-90 mL/min, by oral ingestion or nasogastric tube, with total volumes ranging from 1 to 20 L. The onset of diarrhea occurs as soon as 20 minutes with clearing of the effluent as early as 90 minutes. Faster administration rates appear to shorten overall cleansing time. Two PEG-electrolyte lavage solutions (ELSs) have recently gained FDA approval. The recommended dosage rate is 1.2-1.8 L/hr orally or by nasogastric tube until rectal effluent is clear. In most patients, this requires a maximum of 4-6 L. Initial data indicate that PEG-ELSs are safe for elderly patients and for patients who have an increased risk of fluid overload, but these solutions have not been evaluated in children, pregnant women, or patients with inflammatory bowel disease. WBI is an effective alternative to other regimens for removing fecal material and reducing bowel lumen bacterial counts before colonoscopy and colorectal surgery. Retention of bacterial counts before colonoscopy and colorectal surgery. Retention of excess WBI solution may interfere with the quality of barium enema radiographs; this can be minimized by completing the irrigation the evening before the examination. Gastrointestinal side effects occur in about one third of the patients following WBI, but do not generally require discontinuing the irrigation.

Optimal bowel preparation increases the cecal intubation rate and detection of neoplastic lesions while decreasing the procedural time and procedural-related complications. Although high-volume polyethylene glycol (PEG) solution is the most frequently used preparation for bowel cleansing, patients are often unwilling to take PEG solution due to its large volume, poor palatability, and high incidence of adverse events, such as abdominal bloating and nausea. Other purgatives include osmotic agents (e.g., sodium phosphate, magnesium citrate, and sodium sulfate), stimulant agents (e.g., senna, bisacodyl, and sodium picosulfate), and prokinetic agents (e.g., cisapride, mosapride, and itopride). A combination of PEG with an osmotic, stimulant, or prokinetic agent could effectively reduce the PEG solution volume and increase patients’ adherence. Some such solutions have been found in several published studies to not be inferior to PEG alone in terms of bowel cleansing quality. Although combination methods showed similar efficacy and safety, the value of these studies is limited by shortcomings in study design. New effective and well-tolerated combination preparations are required, in addition to rigorous new validated studies. PMID:26973388

Full Text Available Abstract Background Irritable bowel syndrome (IBS and inflammatory bowel disease (IBD symptoms often overlap. In some IBS cases there are subtle inflammatory changes similar to the immune-mediated pathophysiology of IBD, and the risk of both increases after infectious gastroenteritis (IGE. Methods To evaluate the effect of IBS and IGE on IBD risk utilizing US Department of Defense medical encounter data, active duty personnel with IBS were matched to subjects without IBS. Medical encounter history was analyzed to assess for incident IBD. IGE was identified from documented medical encounters and by self-report. Relative risks were calculated using Poisson regression models. Results We identified 9,341 incident IBS cases and 18,678 matched non-IBS subjects and found an 8.6-fold higher incidence (p p  Conclusions These data reflect a complex interaction between illness presentation and diagnosis of IBS and IBD and suggest intercurrent IGE may increase IBD risk in IBS patients. Additional studies are needed to determine whether IBS lies on the causal pathway for IBD or whether the two are on a pathophysiological spectrum of the same clinical illness. These data suggest consideration of risk reduction interventions for IGE among IBS patients at high disease risk.

In 20 healthy Peruvians aerobic cultures were done of upper small bowel contents, obtained following the method of the string capsule or Enterotest, and of faringeal material, obtained doing gargles with sterilized water. In 15 (75%) of the 20 subjects cultures of small bowel contents either were sterile (in 5 subjects, or 25% of the total) or revealed only diverse aerobic germs (in 10 subjects, or 50% of the total), the germs more frequently found being: negative coagulase staphylococcus albus (in 7 subjects, or 35% of the total), alpha hemolytic streptococcus (in 4 subjects, or 20% of the total) and Neisseria catarrhalis (in 4 subjects, or 20% of the total). In 5 (25%) of the 20 subjects, coliform bacteria were found in the upper small bowel (Klebsiella pneumonia in 2, and Escherichia coli in the remaining 3). Of those 5 subjects, only 2 (10% or the total of 20) had the microorganisms exclusively in the bowel, and in both the concentration of germs was 10(4)/ml. On the contrary, the 3 remaining subjects (15% of the total) had coliforms also in the pharynx; in 2 of the 3 subjects the concentration of germs found in the bowel was 10(3)/ml, and, in the remaining one, 10/ml; only one of the 3 subjects presented germs in the pharynx in a greater concentration than in the bowel, while another presented germs in the same concentration in both localizations, and the remaining one presented germs in the bowel in a concentration lower than in the pharynx.(ABSTRACT TRUNCATED AT 250 WORDS)

The radiolesions of the small bowel

International Nuclear Information System (INIS)

Bories-Azeau, A.; Dayan, L.

1980-01-01

The irradiation of the pelvic abdominal cancers extends beyond the centre of the tumour and may induce actinic digestive lesions. The bowel and more rarely the small bowel -which is the subject-matter of our study- are concerned by those radiolesions that are favoured by therapeutic overdose, post-operative adhesions fastening the bows, radio-surgical or chemicostatic associations, and lastly by vascular or nutritive deficiencies. One may distinguish between two kinds of lesions, depending on the lapse of time before their coming out and on the symptoms. The early or acute types are characterized by a radio-mucitis and give an exsudative enteropathy with anorexia, vomiting, diarrhoea and loss of weight, of which the diagnosis is easy because it occurs during the irradiation and lessens at the end of the treatment. The late radiolesions of the small bowel are characterized by sclerosis and chronic endarteritis and, after a longlasting period of latency, give varied symptoms: disordered intestinal transit which sometimes is irreversible, perforation, fistula, syndrome of malabsorption, giving often rise to be mistaken for a recurrence of the cancer. The treatment varies whether the lesion is segmental or diffuse. In the first case, the failure of the medical means accounts for the surgical cutting away or the internal derivation; in the second case, the digestive mutilation which would result from an enlargement of the lesion commands to be more cautious and to call for the methods of parenteral feeding and digestive setting to rest [fr

Placebo effect in clinical trial design for irritable bowel syndrome.

Ongoing efforts to improve clinical trial design in irritable bowel syndrome have been hindered by high placebo response rates and ineffective outcome measures. We assessed established strategies to minimize placebo effect as well as the various ap-proaches to placebo effect which can affect trial design. These include genetic markers such as catechol-O-methyltransferase, opioidergic and dopaminergic neurobiologic theory, pre-cebo effect centered on expectancy theory, and side effect unblinding grounded on conditioning theory. We reviewed endpoints used in the study of IBS over the past decade including adequate relief and subjective global relief, emphasizing their weaknesses in fully evaluating the IBS condition, specifically their motility effects based on functional net value and relative benefit-harm based on dropouts due to adverse events. The focus of this review is to highlight ongoing efforts to improve clinical trial design which can lead to better outcomes in a real-world setting.

Context: In irritable bowel syndrome (IBS), disturbance of bowel motility is associated with infiltration of inflammatory mediators and cytokines into the intestine, such as neutrophils, myeloperoxidase (MPO), tumor necrosis factor alfa (TNF-α), and lipid peroxide. Aims: Regarding promising anti-inflammatory and anti-oxidative effects of Hypericum perforatum (HP) extract, besides its anti-depressant effect, this study was designed to evaluate the effects of HP in an experimental model of IBS. Settings and Design: IBS was induced by a 5-day restraint stress in rats. The HP extract was administered by gavage in doses of 150, 300, and 450 mg/kg for 26 days. Fluoxetine and loperamide were used as positive controls. Gastric emptying and small bowel and colon transit, besides the levels of TNF-α, MPO, lipid peroxidation, and antioxidant power, were determined in colon homogenates. Statistical Analysis Used: Data were analyzed by one-way ANOVA followed by Tukey's post hoc test for multiple comparisons. Results: A significant reduction in small bowel and colonic transit (450 mg/kg), TNF-α, MPO, and lipid peroxidation and an increase in antioxidant power in all HP-treated groups (150, 300, and 450 mg/kg) were seen as compared with the control group. Gastric emptying did not alter significantly when compared with the control group. Treatment with loperamide (10 mg/kg) significantly inhibited gastric emptying and small bowel and colonic transit, while flouxetine (10 mg/kg) decreased gastric emptying, TNF-α, MPO, and lipid peroxidation and increased the antioxidant power of the samples in comparison with the control group. Conclusions: HP diminished the recruitment of inflammatory cells and TNF-α following restraint stress not in a dose-dependent manner, possibly via inhibition of MPO activity and increasing colon antioxidant power, without any difference with fluoxetine. The HP extract inhibits small bowel and colonic transit acceleration like loperamide but has minimal

Midgut volvulus, the most common serious complication of malrotation, can be diagnosed using conventional contrast fluoroscopy, US or CT. CT is a quick and comprehensive examination in the evaluation of complex acute abdominal pathology in children. Contrast-enhanced CT can readily help the radiologist recognize perfusion abnormalities of the bowel, which is vital for reducing morbidity and mortality in affected children. Our case emphasizes and demonstrates additional CT features of bowel infarction in a child with a proven malrotation with midgut volvulus. (orig.)

Small bowel obstruction in percutaneous fixation of traumatic pelvic fractures

Directory of Open Access Journals (Sweden)

Roberto Bini

2013-01-01

Full Text Available The use of external fixation for the initial treatment of unstable, complex pelvic injuries with hemodynamic instability remains an effective treatment for multiply injured patients. Bowel entrapment within a pelvic fracture is a rarely reported, potentially fatal complication. Here, we report a polytrauma patient with pelvic fractures who developed an intestinal obstruction after an external fixation. At an explorative laparotomy, we found an ileum segment trapped in the sacral fracture. Reported cases of bowel entrapment in pelvic fractures, especially in sacral fractures, are exceedingly rare. The diagnosis is often delayed due to difficulty distinguishing entrapment from the more common adynamic ileus. In conclusion, clinicians and radiologists should be aware of this potentially lethal complication of pelvic fractures treatment. To exclude bowel entrapment, patients with persistent ileus or sepsis should undergo early investigations.

Full Text Available Background Functional gastrointestinal (GI disorders are very common and many patients with such disorders are not satisfied with treatment outcomes. Psychological aspects of functional disorders need special attention that may play an important role in patient management. Objectives In this study, psychology evaluation was performed for a population of patients with functional bowel disorders. Patients and Methods One hundred patients with functional bowel disorders including 50 patients with irritable bowel syndrome (IBS referred to GI clinics were candidates for psychiatry evaluation; of those 60 patients completed the study. Psychiatric disorders were diagnosed using a structured clinical interview based on diagnostic and statistical manual of mental disorders IV (DSM IV. Results Of 60 patients with functional bowel disorders (including 39 IBS, 51 (85% were diagnosed with at least one psychiatry disorder. The most common disorders were dysthymia (25% and obsessive-compulsive disorder (20%. There was no significant difference between IBS patients and other functional bowel disorders regarding the prevalence of psychiatric disorders. Conclusions Psychiatric disorders are very prevalent among patients with functional bowel disorders. Prompt diagnosis and appropriate management of associated psychiatric disorders along with GI targeted treatments may lead to a better outcome in these patients.

To identify CT findings predictive of surgical management in non-emergency small bowel obstruction (SBO). Contrast-enhanced abdominal CT of 129 patients with non-emergency SBO were evaluated for small bowel luminal diameter, wall thickness, presence of the small bowel faeces sign (intraluminal particulate matter in a dilated small bowel) and length, transition point, submucosal oedema, mesenteric stranding, ascites and degree of obstruction (low grade partial, high grade partial and complete obstruction). Medical records were reviewed for age, gender, management and history of abdominal surgery, abdominal malignancy, or SBO. Statistical analyses were performed with Stata Release 9.2. Degree of obstruction was the only predictor of need for surgery. Whereas 18.0% of patients with low-grade partial obstruction (n = 50) underwent surgery, 32.5% of patients with high-grade partial obstruction (n = 77) and 100% of patients with complete obstruction (n = 2) required surgery (P = 0.004). The small bowel faeces sign was inversely predictive of surgery (P = 0.018). In non-emergency SBO patients with contrast-enhanced CT imaging, grade of obstruction predicts surgery, while the small bowel faeces sign inversely predicts need for surgery. (orig.)

2000-10-01

Technetium-99m-labeled leukocyte (WBC) imaging is a valuable screening method for inflammatory bowel disease, especially in children, because of its high rate of sensitivity, low cost, and ease of preparation. A 14-year-old girl is described who had juvenile arthritis and iritis complicated by inflammatory bowel disease. She was examined for recurrent abdominal pain. A Tc-99m stannous colloid WBC scan was performed, and tracer accumulation was seen in the small bowel in the region of the distal ileum on the initial 1-hour image. Delayed imaging at 3 hours also revealed tracer accumulation in the cecum and ascending colon, which was not seen on the early image. A biopsy of the colon during endoscopy showed no evidence of active inflammation in the colon. The small bowel was not seen. Computed tomography revealed changes suggestive of inflammatory bowel disease in the distal ileum. The appearance on the WBC study was most likely a result of inflammatory bowel disease involving the distal ileum, with transit of luminal activity into the large bowel.

The effect of barium infusion rate on the diagnostic value of small bowel enteroclysis

Oudkerk, M.; Rijke, A.M.

1988-01-01

Although enteroclysis may have many advantages over the conventional methods of small bowel examination, the contrast material is not always infused at a rate appropriate to gain maximum diagnostic information. In this study, 190 patients were examined by small bowell enteroclysis at five contrast infusion rates ranging from 50 to 150 ml/min using a newly designed infusion pump system. The results show that at rates above 75 ml/min, motility disturbances are masked by small bowel dilatation and paralysis, transit times are extended and morphological detail is obscured. At rates below 75 ml/min, incomplete filling of the loops renders optimal diagnostic evaluation impossible. An infusion rate of 75 ml/min was found to be optimal for initiating small bowel studies. This rate can be adjusted for individual cases when pathology or drugs affect the motility of the small bowel. 13 refs.; 5 figs.; 1 table

Objectives Irritable bowel syndrome (IBS) is a chronic, disabling condition that greatly compromises patient functioning. The aim of this study was to assess the impact of a 6-week twice per week Iyengar yoga (IY) program on IBS symptoms in adolescents and young adults (YA) with IBS compared with a usual-care waitlist control group. Methods Assessments of symptoms, global improvement, pain, health-related quality of life, psychological distress, functional disability, fatigue, and sleep were collected pre- and posttreatment. Weekly ratings of pain, IBS symptoms, and global improvement were also recorded until 2-month follow-up. A total of 51 participants completed the intervention (yoga = 29; usual-care waitlist = 22). Results Baseline attrition was 24%. On average, the yoga group attended 75% of classes. Analyses were divided by age group. Relative to controls, adolescents (14–17 years) assigned to yoga reported significantly improved physical functioning, whereas YA (18–26 years) assigned to yoga reported significantly improved IBS symptoms, global improvement, disability, psychological distress, sleep quality, and fatigue. Although abdominal pain intensity was statistically unchanged, 44% of adolescents and 46% of YA reported a minimally clinically significant reduction in pain following yoga, and one-third of YA reported clinically significant levels of global symptom improvement. Analysis of the uncontrolled effects and maintenance of treatment effects for adolescents revealed global improvement immediately post-yoga that was not maintained at follow-up. For YA, global improvement, worst pain, constipation, and nausea were significantly improved postyoga, but only global improvement, worst pain, and nausea maintained at the 2-month follow-up. Conclusions The findings suggest that a brief IY intervention is a feasible and safe adjunctive treatment for young people with IBS, leading to benefits in a number of IBS-specific and general functioning domains for

There is an ongoing debate on the use of antibiotics instead of appendectomy for treating appendicitis but diagnostic difficulties and longstanding inflammation might lead to increased incidence of bowel cancer in these patients. The aim of this population-based study was to investigate the incidence of bowel cancer after non-surgical treatment of appendicitis. Patients diagnosed with appendicitis but lacking the surgical procedure code for appendix removal were retrieved from the Swedish National Inpatient Register 1987-2013. The cohort was matched with the Swedish Cancer Registry and the standardised incidence ratios (SIR) with 95% confidence interval (95% CI) for appendiceal, colorectal and small bowel cancers were calculated. Of 13 595 patients with non-surgical treatment of appendicitis, 352 (2.6%) were diagnosed with appendiceal, colorectal or small bowel cancer (SIR 4.1, 95% CI 3.7-4.6). The largest incidence increase was found for appendiceal (SIR 35, 95% CI 26-46) and right-sided colon cancer (SIR 7.5, 95% CI 6.6-8.6). SIR was still elevated when excluding patients with less than 12 months since appendicitis and the incidence of right-sided colon cancer was elevated five years after appendicitis (SIR 3.5, 95% CI 2.1-5.4). An increased incidence of bowel cancer was found after appendicitis with abscess (SIR 4.6, 95% CI 4.0-5.2), and without abscess (SIR 3.5, 95% CI 2.9-4.1). Patients with non-surgical treatment of appendicitis have an increased short and long-term incidence of bowel cancer. This should be considered in the discussion about optimal management of patients with appendicitis.

Evaluate the factor structure of youth and maternal involvement ratings on the Inflammatory Bowel Disease Family Responsibility Questionnaire, a measure of family allocation of condition management responsibilities in pediatric inflammatory bowel disease. Participants included 251 youth aged 11-18 years with inflammatory bowel disease and their mothers. Item-level descriptive analyses, subscale internal consistency estimates, and confirmatory factor analyses of youth and maternal involvement were conducted using a dyadic data-analytic approach. Results supported the validity of 4 conceptually derived subscales including general health maintenance, social aspects, condition management tasks, and nutrition domains. Additionally, results indicated adequate support for the factor structure of a 21-item youth involvement measure and strong support for a 16-item maternal involvement measure. Additional empirical support for the validity of the Inflammatory Bowel Disease Family Responsibility Questionnaire was provided. Future research to replicate current findings and to examine the measure's clinical utility is warranted.

Full Text Available Merkel cell carcinoma (MCC is an uncommon cutaneous malignant tumor that presents as a rapidly growing skin nodule on sun-exposed areas of the body. MCC is aggressive with regional nodal and distant metastases to the skin, lung, and bones. There have been no reports of metastatic MCC to the mesentery and 6 reports describing metastasis to the small intestine. We present a case of metastatic MCC to the mesentery with infiltration to the small bowel, 8 years after original tumor resection. This is the 5th metastasis and it encased the small bowel resulting in a hair-pin loop contributing to the unusual clinical presentation. Although MCC metastatic to the bowel is uncommon, it is not rare. It is important to recognize the unusual manifestations of this disease as they are becoming more common in the future. Routine radiologic surveillance and thorough review of systems are important to patient follow-up.

Aim: To validate a newly developed software prototype that automatically analyses small bowel motility by comparing it directly with manual measurement. Material and methods: Forty-five patients with clinical indication for small bowel magnetic resonance imaging (MRI) were retrospectively included in this institutional review board-approved study. MRI was performed using a 1.5 T system following a standard MR-enterography protocol. Small bowel motility parameters (contractions-per-minute, luminal diameter, amplitude) were measured three times each in identical segments using the manual and the semiautomatic software-assisted method. The methods were compared for agreement, repeatability, and time needed for each measurement. All parameters were compared between the methods. Results: A total of 91 small-bowel segments were analysed. No significant intra-individual difference (p > 0.05) was found for peristaltic frequencies between the methods (mean: 4.14/min manual; 4.22/min software-assisted). Amplitudes (5.14 mm; 5.57 mm) and mean lumen diameters (17.39 mm; 14.68) differed due to systematic differences in the definition of the bowel wall. Mean duration of single measurement was significantly (p < 0.01) shorter with the software (6.25 min; 1.30 min). The scattering of repeated measurements was significantly (p < 0.05) lower using the software. Conclusion: The software-assisted method accomplished highly reliable, fast and accurate measurement of small bowel motility. Measurement precision and duration differed significantly between the two methods in favour of the software-assisted technique

Small and large bowel volvulus are uncommon causes of bowel obstruction with nonspecific clinical manifestations which may delay the diagnosis and increase morbidity. Therefore, radiologists play an important role in promptly establishing the diagnosis, recognizing underlying congenital or acquired risk factors and detecting potentially life-threatening complications. Multidetector CT performed with intravenous contrast is currently the preferred modality for the evaluation of volvulus, which is best appreciated when imaging is perpendicular to the axis of bowel rotation, hence the benefit of multiplanar reformations. In this pictorial essay we review the pathophysiology of the different types of intestinal volvulus, discuss diagnostic criteria for prompt diagnosis of volvulus and emphasize early recognition of the complications.

We describe the clinical presentation, evaluation, management and outcome of patients experiencing small bowel perforation following radiation therapy for cervical cancer. A database consisting of 95 Japanese women with stage 0-4 A cervix cancer treated between 1991 and 2004 contained seven patients (7.4%) with small bowel perforation. The median age at the time of perforation was 72.5 years (range 62-78). The median time from completion of radiotherapy to perforation was 6 months (range 2-58). Surgery (one small bowel resection and anastomosis with diversion; six small bowel resection and anastomosis) was performed immediately in all seven patients. One of seven patients died of small bowel perforation (i.e. mortality rate was 14%). Bowel adhesion was detected during the operation in only three cases (43%). Signs of peritonitis were absent in six cases (86%). Severe abdominal pain was seen in all seven patients. The perforation site was ileum in all seven cases. In all patients, pathological changes were compatible with postirradiation injury of the gastrointestinal tract. The presenting complaints of patients with bowel perforation following radiotherapy vary, and signs of peritonitis may be absent. Emergency physicians must be alert for these complications in patients who have been treated with radiotherapy.

Full Text Available Background: High-quality bowel preparation is crucial for achieving the goals of colonoscopy. However, choosing a bowel preparation in clinical practice can be challenging because of the many formulations. This study aims to assess the impact the type of bowel preparation on the quality of colonoscopy in a community hospital setting. Methods: A retrospective, observational study was conducted utilizing a colonoscopy screening/surveillance database in central Illinois during the period of January 1, 2010, to March 31, 2014. Patients without bowel preparation assessment were excluded from this study. Controlling for the confounders, generalized linear models were used to estimate the adjusted impact [odds ratio (OR] of bowel preparation type on the quality of preparation (excellent, good, fair, and poor, and on the detection of advanced adenoma. The association between the time of withdrawal after insertion and the quality of preparation was also examined using a linear model. Results: A total of 28,368 colonoscopies; half the patients were male, and the average age was 61±9 years. Polyethylene glycol (PEG was used in the majority (70.2% of bowel preparations, followed by sodium sulfate (21.4%, sodium phosphate (2.5%, magnesium sulfate (0.4%, and others. Compared with PEG, magnesium sulfate had a poorer quality of bowel preparations (OR=0.6, 95% CI 0.4–0.9; p<0.05, whereas the quality of bowel preparation was significantly improved by using sodium sulfate (OR=5.7, 95% CI 5.4–6.1; p<0.001 and sodium phosphate (OR=2.1, 95% CI 1.8–2.5; p<0.001. For those who had adequate bowel preparation, the better quality of preparation significantly increased the detection rate of advanced adenoma (5.0, 3.6, and 2.9% for excellent, good, and fair, respectively. Conclusion: When possible, sodium sulfate–based preparations should be recommended in the community setting for colonoscopy because of their high quality of bowel preparation.

Cost Effectiveness of Screening Colonoscopy Depends on Adequate Bowel Preparation Rates - A Modeling Study.

Directory of Open Access Journals (Sweden)

James Kingsley

Full Text Available Inadequate bowel preparation during screening colonoscopy necessitates repeating colonoscopy. Studies suggest inadequate bowel preparation rates of 20-60%. This increases the cost of colonoscopy for our society.The aim of this study is to determine the impact of inadequate bowel preparation rate on the cost effectiveness of colonoscopy compared to other screening strategies for colorectal cancer (CRC.A microsimulation model of CRC screening strategies for the general population at average risk for CRC. The strategies include fecal immunochemistry test (FIT every year, colonoscopy every ten years, sigmoidoscopy every five years, or stool DNA test every 3 years. The screening could be performed at private practice offices, outpatient hospitals, and ambulatory surgical centers.At the current assumed inadequate bowel preparation rate of 25%, the cost of colonoscopy as a screening strategy is above society's willingness to pay (<$50,000/QALY. Threshold analysis demonstrated that an inadequate bowel preparation rate of 13% or less is necessary before colonoscopy is considered more cost effective than FIT. At inadequate bowel preparation rates of 25%, colonoscopy is still more cost effective compared to sigmoidoscopy and stool DNA test. Sensitivity analysis of all inputs adjusted by ±10% showed incremental cost effectiveness ratio values were influenced most by the specificity, adherence, and sensitivity of FIT and colonoscopy.Screening colonoscopy is not a cost effective strategy when compared with fecal immunochemical test, as long as the inadequate bowel preparation rate is greater than 13%.

[Towards new therapeutic paradigms beyond symptom control in the management of inflammatory bowel diseases.

Inflammatory bowel diseases, Crohn's disease and ulcerative colitis are chronic relapsing conditions that may result in progressive bowel damage, high risk of complications, surgery and permanent disability. The conventional therapeutic approach for inflammatory bowel diseases is based mainly on symptom control. Unfortunately, a symptom-based therapeutic approach has little impact on major long-term disease outcomes. In other chronic disabling conditions such as diabetes, hypertension and rheumatoid arthritis, the development of new therapeutic approaches has led to better outcomes. In this context a "treat to target" strategy has been developed. This strategy is based on identification of high-risk patients, regular assessment of disease activity by means of objective measures, adjustment of treatment to reach the pre-defined target. A treat to target approach has recently been proposed for inflammatory bowel disease with the aim at modifying the natural history of the disease. In this review, the evidence and the limitations of the treat to target paradigm in inflammatory bowel disease are analyzed and discussed.

Arora, Manish

2008-01-01

Objective: To assess the efficacy of low-volume powder polyethylene glycol (PEG)-3350 as a sole bowel preparation for colonoscopy. Methods: This case series examined 245 consecutive patients (a mixture of inpatients and outpatients undergoing screening colonoscopy) at a hospital endoscopy center over a 2-year period. The patients received powder PEG-3350 in the amount of 204 g dissolved in 32 oz of water and taken in 3 divided doses 1 hour apart with 8 oz of water in between each dose. Colon preparation scores (CPS) were used to assess the quality of colon cleansing. The results obtained from the 245 patients were collated and compared to those of patients receiving sodium phosphate, the historical control. Results: The mean CPS was calculated to be 3.43, with a standard deviation of 1.12. Of the 245 patients, 92 were scored with a grade of 4, and 5 patients had incomplete colonoscopies secondary to failure of bowel preparation (CPS=0). Among the remaining patients, 22 and 26 were graded as poor (CPS=1) or fair (CPS=2) bowel preparations, respectively. Conclusion: The low-volume powder PEG-3350 formula used in our case series showed effective colon cleansing and may be considered for use as a sole bowel preparation. PMID:21960925

Aim: To investigate the frequency, clinical significance, and outcome of small-bowel intussusceptions in adults detected using ultrasound in an outpatient setting. Patients and methods: In two different retrospective (January 2001 to April 2003) and prospective (May 2003 to June 2005) periods, 33 small-bowel intussusceptions were found in 32 patients (13 females; mean age: 38.1 years) with known or suspected intestinal disease. Patients underwent diagnostic work-up to assess any organic disease. Patients with self-limiting intussusception were submitted to clinical and ultrasonographic follow-up. Results: Of the 32 patients with small-bowel intussusception, 25 were identified in the prospective series of 4487 examinations (0.53%) and seven in the retrospective series of 5342 examinations (0.15%; p = 0.002). Four patients had persistent and 28 self-limiting intussusceptions. Self-limiting intussusceptions were idiopathic in 11 patients (39%) or associated with organic diseases in 17 (Crohn's disease in 11 patients, celiac disease in three, ulcerative colitis in one patient, and previous surgery for cancer in two). Self-limiting intussusceptions were asymptomatic in 25% of patients. Conclusion: Small-bowel intussusceptions in adults are not rare and are frequently self-limiting, idiopathic, or related to organic diseases, mainly Crohn's disease and coeliac disease.

Guo, Jian-long; Bao, Yan-ping; Wang, Min

2017-12-01

During the production of Ti-bearing Al-killed ultra-low-carbon (ULC) steel, two different heating processes were used when the converter tapping temperature or the molten steel temperature in the Ruhrstahl-Heraeus (RH) process was low: heating by Al addition during the RH decarburization process and final deoxidation at the end of the RH decarburization process (process-I), and increasing the oxygen content at the end of RH decarburization, heating and final deoxidation by one-time Al addition (process-II). Temperature increases of 10°C by different processes were studied; the results showed that the two heating processes could achieve the same heating effect. The T.[O] content in the slab and the refining process was better controlled by process-I than by process-II. Statistical analysis of inclusions showed that the numbers of inclusions in the slab obtained by process-I were substantially less than those in the slab obtained by process-II. For process-I, the Al2O3 inclusions produced by Al added to induce heating were substantially removed at the end of decarburization. The amounts of inclusions were substantially greater for process-II than for process-I at different refining stages because of the higher dissolved oxygen concentration in process-II. Industrial test results showed that process-I was more beneficial for improving the cleanliness of molten steel.

Gallstone Ileus: An Unlikely Cause of Mechanical Small Bowel Obstruction

2017-06-01

Full Text Available Gallstone ileus is a rare disease that accounts for 1–4% of intestinal obstructions. Almost exclusively a condition in the older female population, it is a difficult diagnosis to make. We report the case of gallstone ileus in a 94-year-old Caucasian female, who presented to the emergency department with acute-onset nausea, coffee-ground emesis, lack of bowel movement, and abdominal distension. On CT scan, the diagnosis of gallstone ileus was made by the presence of a cholecystoduodenal fistula, pneumobilia, and small bowel obstruction. Emergent laparotomy with a one-stage procedure of enterolithotomy and stone removal by milking the bowel distal to the stone were performed. The postoperative course was uneventful until postoperative day 4 when the patient was found tachycardic, lethargic, and unresponsive. We reviewed the literature on the diagnosis and treatment of gallstone ileus.

Is there a role for prophylactic colectomy in Lynch syndrome patients with inflammatory bowel disease?

McNamara, Kate L; Aronson, Melyssa D; Cohen, Zane

2016-01-01

Lynch syndrome and chronic inflammatory bowel disease are two important risk factors for colorectal cancer. It is unclear whether Lynch syndrome patients with inflammatory bowel disease are at sufficiently increased risk for colorectal cancer to warrant prophylactic colectomy. This study aims to identify all cases of Lynch syndrome and concurrent inflammatory bowel disease in a large familial gastrointestinal cancer registry, define incidence of colorectal cancer, and characterize mismatch repair protein gene mutation status and inflammatory bowel disease-associated colorectal cancer risk factors. We retrospectively identified and collected clinical data for all cases with confirmed diagnoses of Lynch syndrome and inflammatory bowel disease in the Familial Gastrointestinal Cancer Registry at Mount Sinai Hospital in Toronto, Canada. Twelve cases of confirmed Lynch syndrome, and concurrent inflammatory bowel disease were identified. Four cases developed colorectal cancer. An additional five cases had colectomy; one was performed for severe colitis, and four were performed for low-grade dysplasia. None of these surgical specimens contained malignancy or high-grade dysplasia. The presentation of Lynch syndrome with inflammatory bowel disease is uncommon and not well described in the literature. This small but important series of twelve cases is the largest reported to date. In this series, patients with Lynch syndrome and concurrent inflammatory bowel disease do not appear to have sufficiently increased risk for colorectal cancer to recommend prophylactic surgery. Therefore, the decision to surgery should continue to be guided by surgical indications for each disease. Further evaluation of this important area will require multi-institutional input.

Full Text Available Abstract Background Irritable Bowel Syndrome (IBS is a functional bowel disorder characterised by episodes of abdominal pain associated with altered bowel habits. Many IBS sufferers believe that diet may play a role in triggering these episodes and may avoid certain foods. However relatively few studies have undertaken a dietary assessment in IBS sufferers to examine the wider impact of the condition upon diet. Methods 104 individuals with IBS were recruited and asked to complete a validated food frequency questionnaire (FFQ. The data were analysed against Dietary Reference Values for food energy and nutrients for the United Kingdom and observed intakes for the general population and for differences between IBS subtypes and the UK population. Results The data show that the dietary intakes of this population of IBS sufferers met the UK Dietary Reference Values. The average energy intake of the population exceeded the Estimated Average Requirements of the UK population and the balance of macronutrients was favourable. Intakes of selected micronutrients significantly exceeded the reference nutrient intakes. There were no differences between IBS subtypes. Conclusions The IBS subpopulation appear to have an adequate and balanced macronutrient intake with no evidence of inadequate micronutrient intake.

Patients with irritable bowel syndrome (IBS) show a wide range of symptoms including diarrhea, abdominal pain, changes in bowel habits, nausea, vomiting, headache, anxiety, depression and cognitive impairment. Methylglyoxal has been proved to be a potential toxic metabolite produced by intestinal bacteria. The present study was aimed at investigating the correlation between methylglyoxal and irritable bowel syndrome. Rats were treated with an enema infusion of methylglyoxal. Fecal water content, visceral sensitivity, behavioral tests and serum 5-hydroxytryptamine (5-HT) were assessed after methylglyoxal exposure. Our data showed that fecal water content was significantly higher than controls after methylglyoxal exposure except that of 30 mM group. Threshold volumes on balloon distension decreased in the treatment groups. All exposed rats showed obvious head scratching and grooming behavior and a decrease in sucrose preference. The serum 5-HT values were increased in 30, 60, 90 mM groups and decreased in 150 mM group. Our findings suggested that methylglyoxal could induce diarrhea, visceral hypersensitivity, headache as well as depression-like behaviors in rats, and might be the key role in triggering systemic symptoms of IBS.

A series of 21 subjects (2 males and 19 females) affected with systemic sclerosis, was examined by small bowel (oral and intubation methods) and colon enema. The underlying process responsible for abnormalities in the small bowel and colon in systemic sclerosis is a variable and pacthy destruction of the muscularis propria, that produces the structural and functional changes detected on X-ray: Pathologic condition is the same affecting the esophagus. The scout film of the abdomen often reveals colonic distension and fecal impaction, so that it may be quite difficult to prepare adequately the patients for a barium enema. Peristalsis may be virtually absent in short segments, and transit time may be several time longer than that in normal patients. For these reasons, intestinal pseudo-obstruction may appear in systemic sclerosis. The observed radiographic changes are: 1) in the small bowel: a) dilatation of the gut, especially in its proximal portions (duodenum and jejunum), in which the valvulae conniventes are straightened, normal or thinned; b) presence of diverticula, 2-4 cm in diameter, with hemispherical shape without the neck-like opening into the bowel lumen; 2) in the colon, the characteristic finding is an increase in size of individual haustra, forming sacculations or pseudo-diverticula, usually on the antemesenteric border of the transverse colon, better demonstrated on post-evacuation film. Moreover, loss of colonic haustration is also observed associated to colonic elongation and dilatation

Purpose: To evaluate several substances regarding small bowel distension and contrast on balanced steady-state free precession (bSSFP) cine magnetic resonance (MR) images. Material and Methods: Luminal contrast was evaluated in 24 volunteers after oral application of two different contrast agent groups leading to either bright lumen (pineapple, blueberry juice) or dark lumen (tap water, orange juice) on T1-weighted images. Bowel distension was evaluated in 30 patients ingesting either methylcellulose or mannitol solution for limiting intestinal absorption. Fifteen patients with duodeno-jejunal intubation served as the control. Quantitative evaluation included measurement of luminal signal intensities and diameters of four bowel segments, qualitative evaluation assessed luminal contrast and distension on a five-point scale. Results: Quantitative and qualitative evaluation of the four contrast agents revealed no significant differences regarding luminal contrast on bSSFP images. Quantitative evaluation revealed significantly lower (P<0.05) small bowel distension for three out of four segments (qualitative evaluation: two out of four segments) for methylcellulose in comparison to the control. Mannitol was found to be equal to the control. Conclusion: Oral ingestion of tap water or orange juice in combination with mannitol is recommended for cine MR imaging of the small bowel regarding luminal contrast and small bowel distension on bSSFP sequences

2015-01-01

AIM: To investigate the efficacy of probiotics in irritable bowel syndrome (IBS) patients. METHODS: PubMed, Cochrane library, Scopus, Google Scholar, and Clinicaltrial.gov databases were searched for literature published between September 2007 and December 2013. The applied Mesh terms were “probiotics,” “irritable bowel syndrome,” and “irritable bowel syndrome treatment.” The collected data contained24 clinical trials, of which 15 were eligible for meta-analysis and nine were reviewed systematically. All studies were randomized placebo-controlled trials in patients with IBS that investigated the efficacy of probiotics in IBS improvement. The Jadad score was used to assess the methodological quality of trials. The quality scale ranges from 0 to 5 points, with a score ≤ 2 indicating a low quality report, and a score of ≥ 3 indicating a high quality report. Relative risk (RR), standardized effect size, and 95%CI were calculated using the DerSimonian-Laird method. The Cochran Q test was used to test heterogeneity with P probiotics to placebo was 1.96 (95%CI: 1.14-3.36; P = 0.01). RR of responders to therapies based on a global symptom score in IBS patients for two included trials comparing probiotics with placebo was 2.43 (95%CI: 1.13-5.21; P = 0.02). For adequate improvement of general symptoms in IBS patients, the RR of seven included trials (six studies) comparing probiotics with placebo was 2.14 (95%CI: 1.08-4.26; P = 0.03). Distension, bloating, and flatulence were evaluated using an IBS severity scoring system in three trials (two studies) to compare the effect of probiotic therapy in IBS patients with placebo, the standardized effect size of mean differences for probiotics therapy was -2.57 (95%CI: -13.05--7.92). CONCLUSION: Probiotics reduce pain and symptom severity scores. The results demonstrate the beneficial effects of probiotics in IBS patients in comparison with placebo. PMID:25780308

A simple technique to reduce small bowel toxicity when irradiating the periaortic area

International Nuclear Information System (INIS)

Hernandez, J.C.; Fine, B.; Herman, T.S.; Rothenberg, M.; Nicol, N.

1996-01-01

Purpose/Objective: Patients receiving periaortic radiation are normally treated in the supine position. We decided to evaluate whether positioning the patient prone on a modified 'belly-board' can reduce the volume of small bowel within the lateral fields in patients receiving four field periaortic radiation. Materials and Methods: Sixteen consecutive women with gynecologic primaries underwent simulation of the periaortic area using a four-field set up (AP, PA, Lats). The fields extended from the top of the L1 vertebral body to the bottom of L5 and had a mean length of 16.2 cm. The AP and PA fields had a width of 8 cm (centered on the midline of the vertebral bodies) while the right and left lateral fields had a width of 4 cm (2 cm anterior and 2 cm posterior to the anterior margin of the vertebral bodies) and did not include the spinal cord. Following oral ingestion of small bowel contrast, simulation films were obtained in the supine position and in the prone position on a modified 'belly-board' (with the pelvic opening extended superiorly to the superior abdomen). It was hypothesized that the prone position on a modified 'belly-board' would allow the abdominal small bowel to fall by gravity away from the periaortic area. We measured the volume of small bowel irradiated through the lateral fields for both the supine and prone-in-belly-board positions using the method described by Gallagher et al. Results: The volume of small bowel included within the lateral fields in the supine position ranged from 164 to 359.5 cc 3 (mean 285 cc 3 ) while placement in the prone-in-bellyboard position reduced the volume of small bowel within the lateral fields to a range of 35-152 cc 3 (mean 86 cc 3 ), an overall reduction of approximately 70% in the volume of small bowel included within lateral fields. Conclusion: The use of lateral fields in the prone-in-bellyboard position allows for significant small bowel sparing through the lateral component of a four-field periaortic set

Vascular Endothelial Dysfunction in Inflammatory Bowel Diseases: Pharmacological and Nonpharmacological Targets

Directory of Open Access Journals (Sweden)

Antonietta Gerarda Gravina

2018-01-01

Full Text Available Inflammatory bowel diseases, including Crohn’s disease and ulcerative colitis, are chronic inflammatory conditions involving primarily the gastrointestinal tract. However, they may be also associated with systemic manifestations and comorbidities. The relationship between chronic inflammation and endothelial dysfunction has been extensively demonstrated. Mucosal immunity and gastrointestinal physiology are modified in inflammatory bowel diseases, and these modifications are mainly sustained by alterations of endothelial function. The key elements involved in this process are cytokines, inflammatory cells, growth factors, nitric oxide, endothelial adhesion molecules, and coagulation cascade factors. In this review, we discuss available data in literature concerning endothelial dysfunction in patients affected by inflammatory bowel disease and we focus our attention on both pharmacological and nonpharmacological therapeutic targets.

Value of cine MRI for better visualization of the proximal small bowel in normal individuals

International Nuclear Information System (INIS)

Torkzad, Michael R.; Blomqvist, Lennart; Vargas, Roberto; Tanaka, Chikako

2007-01-01

While enteroclysis seems to be the most efficacious method in achieving bowel distension, enterographic methods have become widespread due to the unpleasantness of enteroclysis and the radiation involved with positioning the catheter. Cine images in MRI can be done without radiation. Our aim is to see if and how cine MR imaging can improve visualization of bowel loops by capturing them while distended. Ten healthy individuals were asked to drink up to 2,000 ml of an oral solution made locally over a 60-min period. Then they underwent MRI using coronal balanced fast field echo (b-FFE) covering small bowel loops. If the initial exam revealed collapsed bowel loops an additional 50 mg of erythromycine was given intravenously with the subject still in the scanner and then cine imaging was performed. The degree of distension of different segments of the small bowel was measured before and after cine imaging and compared. The distension score was significantly higher after addition of the cine images as well, being only significant for depiction of the duodenum and jejunum. Our preliminary study suggests that cine MRI can give better image depiction of the proximal small bowel in healthy volunteers, perhaps circumventing the need for enteroclysis in some cases. There is a need for validation of these results in patients with small bowel disease. (orig.)

The use of magnetic resonance enterography (MRE) has become a mainstay in the evaluation, assessment and follow up of inflammatory bowel diseases, such as Crohn's disease (CD), thanks to its high image quality and its non-ionizing nature. In particular, the advent of faster MRE sequences less sensitive to image-motion artifacts offers the possibility to obtain visual, structural and functional information of the patient's small bowel. However, the inherent subjectivity of the mere visual inspection of these images often hinders the accurate identification and monitoring of the pathological areas. In this paper, we present a framework that provides quantitative and objective motility information of the small bowel from free-breathing MRE dynamic sequences. After compensating for the breathing motion of the patient, we create personalized peristaltic activity maps via optical flow analysis. The result is the creation of a new set of images providing objective and precise functional information of the small bowel. The accuracy of the new method was also evaluated from two different perspectives: objective accuracy (1.1 ± 0.6 mm/s of error), i.e., the ability of the system to provide quantitative and accurate information about the motility of moving bowel landmarks, and subjective accuracy (avg. difference of 0.7 ± 0.7 in a range of 1 to 5), i.e., the degree of agreement with the subjective evaluation of an expert. Finally, the practical utility of the new method was successfully evaluated in a preliminary study with 32 studies of healthy and CD cases, showing its potential for the fast and accurate assessment and follow up of CD in the small bowel.

Objective: To explore alterations in myoelectric activity of the small bowel in rabbits after transarterial embolization and provide academic basis for assessing bowel viability and management. Methods: Twenty normal rabbits were selected and divided into three groups (2 mg group, n=10; 6 mg group, n=5; control group, n=5). Members of 2 mg group were embolized with PVA 2 mg, those of 6 mg group with PVA 6 mg, and the control group with normal saline 2 ml. After microcatherization embolization, myoelectric activity of the small bowel was recorded for 24 hr using chronically implanted electrodes in conscious rabbits. Results: In 2 mg group, the frequency and the amplitude of slow wave of proximal jejunum were significantly lower in post-embolization period than pre-embolization period [(17.83±0.55) cpm vs (11.59±0.23) cpm(P 0.05) and (0.1632±0.002) mV vs (0.1606±0.003) mV (P>0.05), respectively]. Conclusions: Embolization with PVA evokes significant and passive effect on basal electrical rhythm of small bowel. It could provide academic basis for assessing bowel viability to interventional embolization. (authors)

Small bowel endoscopy with existing endoscopes is limited by problems of discomfort and the technical difficulty of advancing far into the small-bowel. Our aim has been to develop and test wireless capsule endoscopy. Wireless endoscopes, in the form of capsules (11 x 33 mm), were constructed by Given Imaging. These were powered by silver oxide batteries and each contained a CMOS imaging chip and miniature processor, white light emitting diodes (LEDs), a short focal length lens, and a miniature transmitter and antenna. Two video frames per second were transmitted, using radio-frequency (approx. 410 MHz), to an array of aerials attached to the body. The array of aerials can also be used to calculate the position of the capsule in the body. The images were stored on a portable recorder carried on a belt and subsequently downloaded for analysis. The batteries allow more than 5 hours of recording, although the capsule generally passes through the whole small bowel in under two hours. Clear video images of the human bowel were recorded from the pylorus to the caecum. Wireless endoscopy, for the first time, allows painless optical imaging of the whole of the small bowel.

There are a number of gaps in our current quality of care for patients with inflammatory bowel diseases. This review proposes changes that could be made now to improve inflammatory bowel disease care. Evidence from the literature and clinical experience are presented that illustrate best practice for improving current quality of care of patients with inflammatory bowel diseases. Best care for inflammatory bowel disease patients will involve services provided by a multidisciplinary team, ideally delivered at a centre of excellence and founded on current guidelines. Dedicated telephone support lines, virtual clinics and networking may also provide models through which to deliver high-quality, expert integrated patient care. Improved physician-patient collaboration may improve treatment adherence, producing tangible improvements in disease outcomes, and may also allow patients to better understand the benefits and risks of a disease management plan. Coaching programmes and tools that improve patient self-management and empowerment are likely to be supported by payers if these can be shown to reduce long-term disability. Halting disease progression before there is widespread bowel damage and disability are ideal goals of inflammatory bowel disease management. Improving patient-physician communication and supporting patients in their understanding of the evidence base are vital for ensuring patient commitment and involvement in the long-term management of their condition. Furthermore, there is a need to create more centres of excellence and to develop inflammatory bowel disease networks to ensure a consistent level of care across different settings.

Severe ischemic bowel necrosis caused by terlipressin during treatment of hepatorenal syndrome

Directory of Open Access Journals (Sweden)

Hae Rim Kim

2013-12-01

Full Text Available Terlipressin is a vasopressin analogue that is widely used in the treatment of hepatorenal syndrome or variceal bleeding. Because it acts mainly on splanchnic vessels, terlipressin has a lower incidence of severe ischemic complications than does vasopressin. However, it can still lead to serious complications such as myocardial infarction, skin necrosis, or bowel ischemia. Herein we report a case of severe ischemic bowel necrosis in a 46-year-old cirrhotic patient treated with terlipressin. Although the patient received bowel resection, death occurred due to ongoing hypotension and metabolic acidosis. Attention should be paid to patients complaining of abdominal pain during treatment with terlipressin.

Retroperitoneal fibrosis: A rare cause of both ureteral and small bowel obstruction

2006-01-01

Retroperitoneal fibrosis (RPF) is a rare condition of unclear etiology. It can cause ureteral obstruction. We present the unique case of a 54 years old female, who initially presented with spontaneous perforation of the cecum. Upon exploring the abdomen, the classical glistening white, unyielding retroperitoneal fibrosis was encountered. A right hemicolectomy was performed.Subsequently, the patient presented with bilateral ureteral obstruction, and later on with small bowel obstruction. Ureteral obstruction was treated with stents,and small bowel obstruction was treated with bypass.To our knowledge no case of idiopathic RPF presenting with features of both bilateral ureteral and small bowel obstruction has been reported in the literature.

Forty-nine patients with a mean age of 25 months underwent a longitudinal intestinal lengthening procedure for short bowel syndrome (SBS) in our institution. Indications for the operation were dependence on parenteral nutrition in spite of adequate conservative management. The small bowel was lengthened from a mean of 27 cm to a mean of 51 cm. There was no intraoperative mortality. The following early complications occurred in our early series: ischemia of a short bowel segment of 2 cm, requiring resection in two patients, insufficiency of the longitudinal anastomosis in two patients and an intra-abdominal abscess in one. Four of 9 non-survivors died of liver failure and 3 of sepsis. Follow-up showed that 19 patients were weaned from parenteral nutrition after a mean of 9.1 months. Long-term complications encountered were dismotility with malabsorption due to bacterial overgrowth caused by progressive dilatation of the bowel, d-lactic acidosis, cholelithiasis and urolithiasis. A longitudinal intestinal lengthening procedure is an effective and safe surgical approach for SBS, provided it is performed in time, the patient's preoperative condition is optimized and technical surgical details are taken into account.

Hung, Guang-Uei; Tsai, Chien-Chung; Lin, Wan-Yu

2006-01-01

Currently, most studies combine the small bowel transit examination with gastric emptying time examination. There are significant drawbacks to this method. The radiotracer does not enter the small intestine in a bolus and the starting time for transit in the duodenum is difficult to define. This makes the result unreliable. In this study, we used a commercial enteric capsule containing radioactive charcoal to solve these problems. Activated charcoal powder was mixed with Tc-99m pertechnetate and loaded to the enteric capsule which can resist gastric acid and dissolve only in the small intestine, in-vitro stability experiment was performed by immersing these capsules in a colorless phosphate buffer of variable pH which mimicked the condition in stomach and small intestine. In addition, ten healthy Chinese volunteers were included for in-vivo experiment. Anterior and posterior views of abdomen were obtained at regular 30-minute intervals until the eighth hour after administration of the radioactive enteric capsule. Small bowel transit time was calculated. The enteric capsule remained intact for at least 480 minutes in the solution mimicking gastric content (pH=3.0) and disrupted at a mean duration of 227.2 minutes at a pH of 6.8 and at a mean duration of 212.4 minutes at a pH of 7.4 in the solution mimicking pancreaticobiliary secretions. In nine of ten volunteers, the small bowel transit time was between 30 to 270 minutes with a mean transit time of 140 min. In one volunteer, we failed to detect the exact time of small bowel transit because the capsule remained in the stomach throughout the study for up to 8 hours. We consider activated charcoal labeled with Tc-99m pertechnetate using an enteric capsule as the carrier to be a potential radioactive marker for small bowel transit study. (author)

Six patients received beer preparation prior to double contrast barium enema. The beer group scored slightly better (though not statistically significantly) both in the cleanliness and in the mucosal coating of the bowel than the control group with standard preparation. The fluid balance was unaltered. The patients in the beer group felt surprisingly well, likely due to the good fluid and energy balance provided by the beer. The beer preparation could be used in cases, when the patients are ready to intake beer and want to maintain a good nutritional status. (orig.) [de

Multi-centre, retrospective self-report postal survey. To characterise spinal cord injured (SCI) individuals with a stoma, their stoma management and outcomes, to identify sources of information and support for decision making and to explore the impact of a stoma on life satisfaction. Five UK spinal cord injury centres. A study-specific questionnaire accompanied by self-concept, life satisfaction and mood measures, and three simple rating scales for satisfaction, impact and restriction on life were sent to all known ostomates at five participating centres. Respondents were 92 individuals, mean age 56 years, mean duration of injury 26 years, 91% with colostomy. Multiple sources of information were utilised in deciding on surgery; discussion with other SCI ostomates was important. Duration of bowel care, faecal incontinence, bowel-related autonomic dysreflexia, dietary manipulation and laxative use were all significantly reduced following surgery. Rectal mucous discharge was the most common and bothersome post-stoma problem. Satisfaction with stoma was high; provision of sufficient information preoperatively was important, those with ileostomy were more dependent and less satisfied. Life satisfaction and physical self-concept were both lower in this sample than in previously reported samples of SCI individuals without reported bowel difficulties or stoma. The findings of this study of self-selected respondents with a stoma for bowel management after SCI emphasised the benefits of stoma in selected individuals and the importance of timely intervention, the complexity of the associated decision-making and of preoperative counselling. The impact of bowel dysfunction on physical self-concept warrants investigation.

Small bowel tissue engineering using small intestinal submucosa as a scaffold.

Small intestinal submucosa (SIS) is an extracellular matrix used in tissue engineering studies to create de novo abdominal wall, urinary bladder, tendons, blood vessels, and dura mater. The purpose of this study is to evaluate the feasibility of using SIS as a scaffold for small bowel regeneration in an in situ xenograft model. Twenty-three dogs had a partial defect created on the small bowel wall which was repaired with a SIS patch. Four dogs underwent small bowel resection with placement of an interposed tube of SIS. The animals were followed 2 weeks to 1 year. Three of the 23 dogs with SIS placed as a patch died shortly after surgery due to leakage from the site. The other 20 dogs survived up to time of elective necropsy with no evidence of intestinal dysfunction. At necropsy, the bowel circumference in the patched area had no stenosis. Histological evaluation showed the presence of a mucosal epithelial layer, varying amount of smooth muscle, sheets of collagen, and a serosal covering. Architecturally, the layers were not well organized in the submucosal region. An abundance of inflammatory cells was present in the early postoperative period but receded with time. All 4 dogs with a tubular segment of SIS interposed had significant problems. One had partial obstruction at 1 month, and 3 died in the early postoperative period due to leakage. This preliminary study suggests that SIS patches can be used for small bowel regeneration. Tubular segmental replacement is not feasible at this time. Copyright 2001 Academic Press.

Imaging predictors for surgery in children with Crohn disease are lacking. To identify imaging features of the terminal ileum on short-interval bowel ultrasound (US) and MR enterography (MRE) in children with Crohn disease requiring surgical bowel resection and those managed by medical therapy alone. This retrospective study evaluated patients 18 years and younger with Crohn disease undergoing short-interval bowel US and MRE (within 2 months of one another), as well as subsequent ileocecectomy or endoscopy within 3 months of imaging. Appearance of the terminal ileum on both modalities was compared between surgical patients and those managed with medical therapy, with the following parameters assessed: bowel wall thickness, mural stratification, vascularity, fibrofatty proliferation, abscess, fistula and stricture on bowel US; bowel wall thickness, T2 ratio, enhancement pattern, mesenteric edema, fibrofatty proliferation, abscess, fistula and stricture on MRE. A two-sided t-test was used to compare means, a Mann-Whitney U analysis was used for non-parametric parameter scores, and a chi-square or two-sided Fisher exact test compared categorical variables. Imaging findings in surgical patients were correlated with location-matched histopathological scores of inflammation and fibrosis using a scoring system adapted from the Simple Endoscopic Score for Crohn Disease, and a Spearman rank correlation coefficient was used to compare inflammation and fibrosis on histopathology. Twenty-two surgical patients (mean age: 16.5 years; male/female: 13/9) and 20 nonsurgical patients (mean age: 14.8; M/F: 8/12) were included in the final analysis. On US, the surgical group demonstrated significantly increased mean bowel wall thickness (6.1 mm vs. 4.7 mm for the nonsurgical group; P = 0.01), loss of mural stratification (odds ratio [OR] = 6.3; 95% confidence interval [CI]: 1.4-28.4; P = 0.02) and increased fibrofatty proliferation (P = 0.04).

Small intestinal dysplastic lesions are rare and difficult to detect before they progress to cancer. New investigative modalities, such as capsule endoscopy and doubleballoon enteroscopy, are very promising in search for premalignant lesions. Screening patients at high-risk for small bowel neoplasia is the only sensible approach. Duodenal adenoma represents the most easily accessible tumors with the possibility of curative endoscopic resection. Due to the strong association of the small bowel and colonic adenomas, it is always necessary to perform colonoscopy. In young patients, the exclusion of familial polyposis by genetic testing is always mandatory. Patients with celiac disease are especially at risk of developing nonHodgkins lymphomas and adenocarcinomas. There is a high-risk of ampuloma and other adenomas in patients with familial adenomatous polyposis. Patients with prolonged and complicated course of Crohns disease, Peutz Jeghers syndrome and patients with ileoanal pouch have higher risk of adenocarcinoma of the small intestine.

Bowel dysfunction remains a major problem in neonates. Traditional auscultation of bowel sounds as a diagnostic aid in neonatal gastrointestinal complications is limited by skill and inability to document and reassess. Consequently, we built a unique prototype to investigate the feasibility of an electronic monitoring system for continuous assessment of bowel sounds. We attained approval by the Institutional Review Boards for the investigational study to test our system. The system incorporated a prototype stethoscope head with a built-in microphone connected to a digital recorder. Recordings made over extended periods were evaluated for quality. We also considered the acoustic environment of the hospital, where the stethoscope was used. The stethoscope head was attached to the abdomen with a hydrogel patch designed especially for this purpose. We used the system to obtain recordings from eight healthy, full-term babies. A scoring system was used to determine loudness, clarity, and ease of recognition comparing it to the traditional stethoscope. The recording duration was initially two hours and was increased to a maximum of eight hours. Median duration of attachment was three hours (3.75, 2.68). Based on the scoring, the bowel sound recording was perceived to be as loud and clear in sound reproduction as a traditional stethoscope. We determined that room noise and other noises were significant forms of interference in the recordings, which at times prevented analysis. However, no sound quality drift was noted in the recordings and no patient discomfort was noted. Minimal erythema was observed over the fixation site which subsided within one hour. We demonstrated the long-term recording of infant bowel sounds. Our contributions included a prototype stethoscope head, which was affixed using a specially designed hydrogel adhesive patch. Such a recording can be reviewed and reassessed, which is new technology and an improvement over current practice. The use of this

The purpose of this pilot study is to determine whether a deep convolutional neural network can be trained with limited image data to detect high-grade small bowel obstruction patterns on supine abdominal radiographs. Grayscale images from 3663 clinical supine abdominal radiographs were categorized into obstructive and non-obstructive categories independently by three abdominal radiologists, and the majority classification was used as ground truth; 74 images were found to be consistent with small bowel obstruction. Images were rescaled and randomized, with 2210 images constituting the training set (39 with small bowel obstruction) and 1453 images constituting the test set (35 with small bowel obstruction). Weight parameters for the final classification layer of the Inception v3 convolutional neural network, previously trained on the 2014 Large Scale Visual Recognition Challenge dataset, were retrained on the training set. After training, the neural network achieved an AUC of 0.84 on the test set (95% CI 0.78-0.89). At the maximum Youden index (sensitivity + specificity-1), the sensitivity of the system for small bowel obstruction is 83.8%, with a specificity of 68.1%. The results demonstrate that transfer learning with convolutional neural networks, even with limited training data, may be used to train a detector for high-grade small bowel obstruction gas patterns on supine radiographs.

Meckel's diverticulum (MD) is the most common congenital abnormality of the gastrointestinal tract that is prevalent in 2–3% of the population. The lifetime risk of complications is estimated at 4%. Small bowel obstruction is the second most common complication of MD. Among the causes of bowel obstruction, axial torsion of MD is the rarest complication. Urgent surgical treatment is needed in cases of small bowel obstruction associated with torsion of MD. Pre-operative diagnosis of MD as a cause of small bowel obstruction is difficult, because the diagnosis can be made only if the diverticulum is delineated at the site of obstruction. We reported a case of axial torsion of MD with necrosis that caused proximal small bowel perforation in a 21 year old male.

Inflammatory bowel diseases are chronic conditions of unknown etiology, showing a growing incidence and prevalence in several countries, including Italy. Although the etiology of Crohn's disease and ulcerative colitis is unknown, due to the current knowledge regarding their pathogenesis, effective treatment strategies have been developed. Several guidelines are available regarding the efficacy and safety of available drug treatments for inflammatory bowel diseases. Nevertheless, national guidelines provide additional information adapted to local feasibility, costs and legal issues related to the use of the same drugs. These observations prompted the Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) to establish Italian guidelines on the safety of currently available treatments for Crohn's disease and ulcerative colitis. These guidelines discuss the use of aminosalicylates, systemic and low bioavailability corticosteroids, antibiotics (metronidazole, ciprofloxacin, rifaximin), thiopurines, methotrexate, cyclosporine A, TNFα antagonists, vedolizumab, and combination therapies. These guidelines are based on current knowledge derived from evidence-based medicine coupled with clinical experience of a national working group.

To show a new technique of laparoscopic intracorporeal anastomosis for transrectal bowel resection with transvaginal specimen extraction, a technique particularly suited for treatment of bowel endometriosis. Step-by-step explanation of the technique using videos and pictures (educative video). Endometriosis may affect the bowel in 3% to 37% of all endometriosis cases. Bowel endometriosis affects young women, without any co-morbidities and in particular without any vascular disorders. In addition, affected patients often express a desire for childbearing. Radical excision is sometimes required because of the impossibility of conservative treatment such as shaving, mucosal skinning, or discoid resection. Bowel endometriosis should not be considered a cancer, and consequently maximal resection is not the objective. Rather, the goal would be to achieve functional benefit. As a result, resection must be as economic and cosmetic as possible. The laparoscopic approach has proved its superiority over the open technique, although mini-laparotomy is generally performed to prepare for the anastomosis. Total laparoscopic approach in patients with partial bowel stenosis, using the vagina for specimen extraction. This technique of intracorporeal anastomosis with transvaginal specimen extraction enables a smaller resection and avoidance of abdominal incision enlargement that may cause hernia, infection, or pain. When stenosis is partial, this technique seems particularly suited for treatment of bowel endometriosis requiring resection. If stenosis is complete, the anvil can be inserted above the lesion transvaginally. Copyright © 2013 AAGL. Published by Elsevier Inc. All rights reserved.

AIM: The aim of this prospective study was to evaluate the overall findings of conventional enteroclysis (CE) with complementary magnetic resonance enteroclysis (MRE) in small bowel disease. METHODS: The study included 32 patients referred from various clinical departments, with known or suspected small bowel disease and abnormalities on CE. Immediately after CE, true fast imaging with steady-state precession (true FISP), and unenhanced and gadolinium-enhanced T1-weighted fast low-angle shot (FLASH) sequences with fat saturation were obtained. Mucosal, mural and luminal changes of the small bowel were evaluated by each technique. In addition, bowel wall thickening, bowel wall enhancement and perienteric changes were assessed by MRE. The radiological findings obtained were evaluated together as a combination, and the role of MRE in the determination of the activity and complications of the small bowel disease was assessed. Radiological findings were correlated with clinical evaluation and follow-up in all cases, including endoscopy in 14 cases and surgery in 5 cases. RESULTS: MRE provided important supplementary mural and extramural information, including degree of pathological wall thickness, mural enhancement pattern associated with disease activity, perivisceral collection, abscess formation, mesenteric fibrofatty proliferation, lymphadenopathy and increase in perienteric vascularity. Short strictures were not revealed on MRE; however, for patients with a history of abdominal malignancy, MRE helped characterize the level of any obstruction and the extent of the disease. CONCLUSION: We recommend MRE for patients who have findings of advanced inflammatory bowel disease or neoplasm on CE examination. The combination of these two techniques can provide important information on the degree and extent of the disorder.

When is irritable bowel syndrome not irritable bowel syndrome? Diagnosis and treatment of chronic functional abdominal pain.

Science.gov (United States)

Grover, Madhusudan

2012-08-01

Functional abdominal pain syndrome (FAPS) is a distinct chronic gastrointestinal (GI) pain disorder characterized by the presence of constant or frequently recurring abdominal pain that is not associated with eating, change in bowel habits, or menstrual periods. The pain experience in FAPS is predominantly centrally driven as compared to other chronic painful GI conditions such as inflammatory bowel disease and chronic pancreatitis where peripherally acting factors play a major role in driving the pain. Psychosocial factors are often integrally associated with the disorder and can pose significant challenges to evaluation and treatment. Patients suffer from considerable loss of function, which can drive health care utilization. Treatment options are limited at best with most therapeutic regimens extrapolated from pain management of other functional GI disorders and chronic pain conditions. A comprehensive approach to management using a biopsychosocial construct and collaboration with pain specialists and psychiatry is most beneficial to the management of this disorder.

Caregivers are an at-risk population for psychic and physical diseases such as irritable bowel syndrome (IBS). However, it is not known whether providing care for the chronically ill patient can be considered a risk factor for developing IBS. In this study, our aim was to evaluate the prevalence of IBS according to the Rome II criteria in a group of caregivers. A cross-sectional study was conducted through an evaluation of caregivers of chronically ill patients. Subjects completed questionnaires including the Rome II Modular Questionnaire, the Hospital Anxiety and Depression Scale, the Zarit Caregiver Burden Interview (ZCBI) (an instrument for evaluating the burden experienced by caregivers), and the irritable bowel syndrome quality of life (IBS-QoL) questionnaire. Ninety-six primary caregivers (mean age was 43.6 ± 13.7 years and 87% were women) were evaluated. The mean length of time providing care was 37.6 months (3-288 months). Forty-seven caregivers (49%) presented with IBS. The caregivers with IBS had higher scores in the global ZCBI score (47 ± 8 vs 28 ± 8, p = 0.001) and on the anxiety and depression scale (p = 0.001) than those that did not have IBS. A total of 72% were diagnosed with caregiver stress syndrome; 42 of them had IBS according to the Rome II questionnaire (60% vs 18%, p = 0.001, relative risk 3.28, 95% CI: 1.4-7.4). Caregivers of chronically ill patients have a high prevalence of IBS, which is associated with depression, anxiety, and poor QoL. © 2015 John Wiley & Sons Ltd.

Vicious circles in inflammatory bowel disease.

Sonnenberg, Amnon; Collins, Judith F

Inflammatory bowel disease can present with a bewildering array of disease manifestations whose overall impact on patient health is difficult to disentangle. The multitude of disease complications and therapeutic side effects result in conflicting ideas on how to best manage a patient. The aim of the study is to test the usefulness of influence diagrams in resolving conflicts centered on managing complex disease processes. The influences of a disease process and the ensuing medical interventions on the health of a patient with inflammatory bowel disease are modeled by an influence diagram. Patient health is the focal point of multiple influences affecting its overall strength. Any downstream influence represents the focal point of other preceding upstream influences. The mathematics underlying the influence diagram is similar to that of a decision tree. Its formalism allows one to consider additive and inhibitory influences and include in the same analysis qualitatively different types of parameters, such as diagnoses, complications, side effects, and therapeutic outcomes. Three exemplary cases are presented to illustrate the potential use of influence diagrams. In all three case scenarios, Crohn's disease resulted in disease manifestations that seemingly interfered with its own therapy. The presence of negative feedback loops rendered the management of each case particularly challenging. The analyses by influence diagrams revealed subtle interactions among the multiple influences and their joint contributions to the patient's overall health that would have been difficult to appreciate by verbal reasoning alone. Influence diagrams represent a decision tool that is particularly suited to improve decision-making in inflammatory bowel disease. They highlight key factors of a complex disease process and help to assess their quantitative interactions.

99mTc-sucralfate scintigraphy in inflammatory bowel disease

1989-01-01

Technetium-99m-labelled albumin-sucralfate was orally administered to 11 patients (Crohn's disease, 8; ulcerative colitis, 3) and 3 healthy volunteers. Serial scintigraphy was performed, and scintigraphic interpretations were compared with radiographic end endoscopic findings in an open study. It was not possible in any patient to relate the scintigraphic findings to the localizations of inflammatory bowel disease, nor was it possible to distinguish the scans in the patients from the scans of the healthy volunteers. It is concluded the 99m Tc-albumin-sucralfate scintigraphy is of no value in the detection of inflammatory bowel disease. 8 refs

To study the pattern of bowel injuries incurred by induced abortion, and the morbidity and mortality associated with them. All patients with bowel injuries due to induced abortion. Detailed data of all the patients was collected and analyzed. A total of 22 patients, mostly young with an average age of 26.86 years, presented with bowel injuries following induced abortion. Severe hemorrhage occurred in 8(36.4%) patients while 11(50%) had ileal perforation; 9(40.9%) underwent primary repair and 2(9.1%) ileostomy formation. Two (9.1%) patients with jejunal perforation had primary repair, whereas two with both jejunal and ileal perforations underwent resections with anastomosis in one and ileostomy in another. Seven (31.8%) with large gut involvement had colostomy formation. Septicemia and wound infection occurred in 7(31.8%) patients each, faecal fistula and abdominal wound dehiscence in 3(13.6%), and pelvic abscess in 1(4.6%) patient. The total mortality in this series was 6(27.3%) patients. Iatrogenic injuries during induced abortion, most commonly caused by quacks, can be minimized substantially if the procedure is performed by qualified medical personnel in proper health care facilities. There is a need for radical overhauling of the mind set in our society together with legislation. (author)

Objective: To investigate the value of MR enteroclysis with air infusion in the diagnosis of small bowel disease. Methods: Sixteen patients with suspected small bowel disease, but without acute inflammatory disease or bowel obstruction, received MR enteroclysis with air infusion. There were 12 males and 4 females, and their age ranged from 17 to 75 years. 10 patients had abdominal pain, 4 with melena or blood stool, and 2 with diarrhea. The longest course was 7 years, and the shortest 1 week. Before MR imaging, a nasoenteric catheter was inserted into the distal part of duodenum, and about 1000 ml of air was infused through the tube to distend the small bowel. 20 mg of IV anisodamine was given to reduce small-bowel peristalsis. All patients were imaged with fat-saturated Gd-DTPA enhanced coronal and axial T 1 -weighted spin-echo (SE) sequence and fast spoiled gradient echo (FSPGR) sequence. Comparison between the diagnosis of MRI and the results of surgery, pathology or clinic was performed to assess the sensitivity and specificity of MRI. Results: 5 cases were normal, 6 with Crohn disease, 2 with gastric intestinal stromal tumor (GIST), and 1 each of lymphoma, tuberculosis and irritable bowel syndrome. The lumen of normal small bowel in MR enteroclysis was no signal, the wall was outlined as middle signal by intraluminal air and surrounding air-distended bowel and was between 1-3 mm thick, and the diameter of the lumen was between 17-28 mm. Crohn disease showed segmental mural thickening, increased enhancement, luminal stricture, and even extraluminal inflammatory mass or fistula. Intestinal tuberculosis invaded the distal section of ileum, cecum, and the proximal ascending colon, the wall thickened and enhanced apparently, and cecum and proximal ascending colon shortened. GIST showed a mass that was iso-signal on T 1 WI, high signal on T 2 WI, and enhanced significantly after IV Gd-DTPA. 1 recurrent lymphoma of ileum showed mural thickening and increased

The role of psychological factors in the irritable bowel syndrome (IBS) is a matter of debate. The prevalence of psychiatric disorders is high in IBS patients. Positive response to antidepressant therapy and presence of family history of depression in IBS patients have led speculations whether this syndrome might be regarded as an affective spectrum disorder. In this study we tried to examine the possible association of IBS with affective spectrum disorders. Forty IBS patients from gastroenterology outpatient clinics of a university hospital and state hospital, 32 controls with inflammatory bowel disease and 34 healthy hospital workers were included in the study. Psychiatric interviews were done using SCID-NP (Structured Clinical Interview for DSM-Non-patients) and psychological factors were assessed by the SCL-90-R (Symptom Checklist-90-Revised), the Beck Depression Inventory, the Beck Anxiety Scale and the Hamilton Rating Scale for Depression. Family histories were obtained by FH-RDC (Family History Research Diagnostic Criteria). All groups were matched for sociodemographic variables. The prevalence of psychiatric disorders and mood disorders was higher in the IBS group than the control groups. Also IBS group rated higher on anxiety and depression scales than the other groups, where the differences were statistically significant. Presence of positive family history for mood disorders was higher in the IBS group. These results support the hypothesis that IBS might be linked to affective spectrum disorder. Psychiatric assessment and therapy might be useful in the course of irritable bowel syndrome.

With the availability of several bowel cleansing agents, physicians and hospitals performing colonoscopies will often base their choice of cleansing agent purely on acquisition cost. Therefore, an easy to use budget impact model has been developed and established as a tool to compare total colon preparation costs between different established bowel cleansing agents. The model was programmed in Excel and designed as a questionnaire evaluating information on treatment costs for a range of established bowel cleansing products. The sum of costs is based on National Health Service reference costs for bowel cleansing products. Estimations are made for savings achievable when using a 2-litre polyethylene glycol with ascorbate components solution (PEG+ASC) in place of other bowel cleansing solutions. Test data were entered into the model to confirm validity and sensitivity. The model was then applied to a set of audit cost data from a major hospital colonoscopy unit in the UK. Descriptive analysis of the test data showed that the main cost drivers in the colonoscopy process are the procedure costs and costs for bed days rather than drug acquisition costs, irrespective of the cleansing agent. Audit data from a colonoscopy unit in the UK confirmed the finding with a saving of £107,000 per year in favour of PEG+ASC when compared to sodium picosulphate with magnesium citrate solution (NaPic+MgCit). For every patient group the model calculated overall cost savings. This was irrespective of the higher drug expenditure associated with the use of PEG+ASC for bowel preparation. Savings were mainly realized through reduced costs for repeat colonoscopy procedures and associated costs, such as inpatient length of stay. The budget impact model demonstrated that the primary cost driver was the procedure cost for colonoscopy. Savings can be realized through the use of PEG+ASC despite higher drug acquisition costs relative to the comparator products. From a global hospital funding

Bowel rupture due to blunt abdominal trauma is no longer rare, and is among the most challenging problems that confront the physicians and radiologists. It is frequently difficult to diagnose because the symptoms may be trivial during the early stage and masked by more obvious, but less lethal injuries. It is well known that the roentgen examination of the abdomen is also of little value to exclude bowel rupture because of infrequency of positive findings and free gas. The plain films of 23 cases of jejunal rupture and 8 cases of ileal rupture were evaluated to sort and diagnostic features of small bowel rupture caused by blunt abdominal trauma. 1. Free intraperitoneal gas was noted in 6 cases of jejunal rupture (26%) and 1 case of ileal rupture (13%), and definite radiological evidence of free intraperitoneal fluid was present in 16 cases of patients (52%). 2. The contour change of bowel loops such as tapering or indentation were seen in 11 cases of patients (36%), and local opacity along the mesenteric root axis was demonstrated in 19 cases of patients (61%). 3. Paralytic ileus was localized to LUQ in jejunal rupture and to mid-abdomen in ileal rupture, and gastric and transverse-colon distension with gas was noticeable especially in jejunal rupture

Objective: To determine the efficacy and tolerability of tegaserod in the treatment of symptoms of irritable bowel syndrome (IBS) IBS-C patients. Patients and Methods: Tegaserod was administered in a dose of 6 mg (twice-a-day) orally for a period of 6 weeks. Symptoms were assessed before and during treatment using a questionnaire. Results: The mean age of patients was 37.5 years and 81 (69.2%) were males. The study enrolled 117 patients and 101 patients completed the study. Number of bowel movements, symptoms of straining at defecation, stool consistency, bloating, urgency and abdominal pain improved significantly following treatment (p<0.05). Analysis of data in both genders separately showed statistically significant improvement in symptoms of urgency, straining at defecation, abdominal pain and number of bowel movements following treatment. Side effects of diarrhea and vertigo (6 and 1 patients respectively) necessitating discontinuation of treatment were infrequent. Conclusion: Tegaserod given in a dose of 6 mg b.d. is effective and well tolerated in IBS-C patients. It is equally effective in males and females in relieving the symptoms of abdominal pain, bloating, straining at defecation as well as increased in the mean number of bowel movements per week.

Do gastrointestinal symptoms in patients with inflammatory bowel disease (IBD) in apparent remission reflect the coexistence of irritable bowel syndrome (IBS) or subclinical inflammation? The aims of this study were as follows: (i) to prospectively determine the prevalence of IBS symptoms in IBD patients in remission; and (ii) to determine whether IBS symptoms correlate with levels of fecal calprotectin. Remission was defined by physician assessment: Crohn's disease (CD) activity index bowel disease questionnaire), the hospital anxiety and depression scale (HAD), and fecal calprotectin were measured. Rome II criteria for IBS were fulfilled in 37/62 (59.7%) of CD patients and by 17/44 (38.6%) of those with ulcerative colitis (UC). However, fecal calprotectin was significantly elevated above the upper limit of normal in both IBD patient groups, indicating the presence of occult inflammation. Furthermore, calprotectin levels were significantly higher in CD and UC patients with criteria for IBS than in those without IBS-type symptoms. QOL scores were lower and HAD scores higher among UC patients with IBS symptoms in comparison to those who did not have IBS symptoms. IBS-like symptoms are common in patients with IBD who are thought to be in clinical remission, but abnormal calprotectin levels suggest that the mechanism in most cases is likely to be occult inflammation rather than coexistent IBS.

Objective: Endometriosis infiltrating the bowel may be difficult to differentiate from colorectal carcinoma in cases that present with non-specific clinical and imaging features. The aim of this study is to assess the value of MR diffusion-weighted imaging (DWI) in differentiating endometriosis infiltrating the bowel from colorectal carcinoma. Methods: In 66 patients, MR DWI was added to the standard imaging protocol in patients visiting our outdoor MR clinic for the analysis of suspected or known deep infiltrating endometriosis (DIE). In patients diagnosed with DIE infiltrating the bowel on MR imaging, high b-value diffusion-weighted images were qualitatively assessed by two readers in consensus and compared to high b-value diffusion weighted images in 15 patients evaluated for colorectal carcinoma. In addition, ADC values of lesions were calculated, using b-values of 50, 400 and 800 s/mm 2 . Results: A total of 15 patients were diagnosed with DIE infiltrating the bowel on MR imaging. Endometriosis infiltrating the bowel showed low signal intensity on high b-value diffusion-weighted images in all patients, whereas colorectal carcinoma showed high signal intensity on high b-value diffusion-weighted images in all patients. Mean ADC value in endometriosis infiltrating the bowel (0.80 ± 0.06 × 10 −3 mm 2 /s) was significantly lower compared to mean ADC value in colorectal carcinoma (0.86 ± 0.06 × 10 −3 mm 2 /s), but with considerable overlap between ADC values. Conclusion: Only qualitative assessment of MR DWI may be valuable to facilitate differentiation between endometriosis infiltrating the bowel and colorectal carcinoma.

The aim of this study was to explore the perceptions of health care among persons living with inflammatory bowel disease. The quality of care plays an important role in the life of persons with a chronic disease. To define what persons with inflammatory bowel disease perceive as high-quality care, greater focus must be placed on the individual's own perspective of living with the condition. A qualitative exploratory study was conducted based on focus groups. Five focus groups were conducted with adult persons living with inflammatory bowel disease, 14 men and 12 women aged 19-76 years. The interviews were performed between January-June 2014. The perceptions of health care from the perspective of persons living with inflammatory bowel disease were summarised in two categories: 'professional attitudes of healthcare staff' and 'structure of the healthcare organisation'. Persons with inflammatory bowel disease want to be encountered with respect, experience trust and obtain information at the right time. They also expect shared decision-making, communication and to encounter competent healthcare professionals. Furthermore, the expectations on and perceptions of the structure of the healthcare organisation comprise access to care, accommodation, continuity of care, as well as the pros and cons of specialised care. The findings show the importance of establishing a respectful and trusting relationship, facilitating healthcare staff and persons with inflammatory bowel disease to work as a team in fulfilling individual care needs - but there is room for improvement in terms of quality of care. A person-centred approach, which places the individual and her/his family at the centre, considering them experts on their own health and enabling them to collaborate with healthcare staff, seems important to reach a high-quality healthcare organisation for patients with Inflammatory bowel disease. © 2017 The Authors.
