Rome Ⅲ:The functional gastrointestinal disorders, third edition, 2006

Functional gastrointestinal disorders （FGIDs） represent a common and important class of disorders within gastroenterology. Rome Ⅰ, the first edition was published in 1994, with symptom-based diagnostic criteria for FGIDs. These criteria began to change the diagnostic approach to F-GIDs, and no longer considered ＂diagnoses of exclusion＂ but rather ＂diagnoses of inclusion＂. Rome Ⅱ, the second edition published in 2000, resulted from the continual process of analyzing new scientific and clinical evidence in the study of F-GIDs. Rome Ⅱ, diagnostic criteria for irritable bowel syndrome （IBS）, was extended with a focus on the frequency of symptoms occurring twelve weeks （not necessarily consecutive weeks） within twelve months. ROlE Ⅲ, the third edition, conservative one, was published in September 2006, with changes made only where there is good evidence to do so. Some of the differences between Rome Ⅱ and Rome Ⅲ criteria are highlighted in this issue.

Epidemiology of functional gastrointestinal disorders in children and adolescents: A systematic review

To assess the prevalence of functional gastrointestinal disorders (FGIDs) in children and adolescents.METHODSPubMed, EMBASE, and Scopus databases were searched for original articles from inception to September 2016. The literature search was made in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. For inclusion, each study had to report epidemiological data on FGIDs in children between 4 and 18 years old and contain standardized outcome based on Rome II, III or IV criteria. The overall quality of included epidemiological studies was evaluated in accordance with Loney’s proposal for prevalence studies of health literature. Two reviewers assessed each study for data inclusion and extraction. Discrepancies were reconciled through discussion with seniors.RESULTSA total of 659 articles were identified from the databases and 16 through manual search. A total of 43 articles fulfilled the eligibility criteria for full-text reading, with 26 remaining to be included in the final analysis. All studies were written in English and published between 2005 and 2016. Eight (30.8%) articles were performed in North America, five (19.2%) in Latin America, five (19.2%) in Europe, seven (27%) in Asia, and one (3.8%) in Africa. Sample size varied between 114 and 99416 subjects, totaling 132600 individuals. Fourteen (53.9%) studies recruited their target samples from schools, 11 (42.3%) from healthcare settings and the remaining one (3.8%) from online panel community. The overall FGID prevalence rates for student samples ranged from 9.9% to 29% to as high as 87% in clinical samples. Cyclic vomiting, irritable bowel syndrome and functional constipation were the most researched conditions, with a prevalence ranging from 0.2% to 6.2%, 0% to 45.1% and 0.5% to 86.9%, respectively. The qualitative appraisal revealed that most of the studies showed average or below average generalizability.CONCLUSIONThe heterogeneity of the studies on FGIDs must be improved in order to allow comparison. Improvements should include appropriate sampling of representative population, comparable study setting, and consistent data collection.

Stress and sleep quality in doctors working on-call shifts are associated with functional gastrointestinal disorders

To investigate the role of sleep quality and psychosocial problems as predictors of functional gastrointestinal disorders (FGIDs) in doctors that work 24 hour-on-call shifts.METHODSIn this cross-sectional observation study, using the Rome III Questionnaire and Pittsburgh Sleep Quality Index (PSQI), we analyzed 170 doctors with 24 hour-on-call shifts.RESULTSAmong the participants that had experienced a 24 hour-on-call shift within the last 6 mo, 48 (28.2%) had FGIDs. Overall prevalence of irritable bowel syndrome (IBS) and functional dyspepsia (FD) were 16.5% and 17.1%, respectively, with 5.3% exhibiting both. Sleep scores (PSQI) (8.79 ± 2.71 vs 7.30 ± 3.43, P = 0.008), the presence of serious psychosocial alarm (83.3% vs 56.6%, P = 0.004), and the proportion of doctors who experienced over two months of recent on-call work (81.2% vs 68.9%, P = 0.044) were significantly different between individuals with or without FGIDs. Multivariate analysis revealed that presenting serious psychosocial alarm was an independent risk factor for prevalence of FD (OR = 5.47, 95%CI: 1.06-28.15, P = 0.042) and poor sleep quality (PSQI ≥ 6) was a predictor of IBS (OR = 4.17, 95%CI: 1.92-19.02, P = 0.016).CONCLUSIONPhysicians should recognize the role of sleep impairment and psychological stress in the development of FGIDs and a comprehensive approach should be considered to manage patients with FGIDs.

Functional gastrointestinal disorders in inflammatory bowel disease: Time for a paradigm shift?

Recent advances in biological therapies have revolutionalised and redefined treatment targets in inflammatory bowel disease(IBD).There is now a stronger emphasis on achieving the more stringent therapeutic goals of mucosal and histological healing,rather than clinical remission alone.Consequently,the treatment of refractory“functional”gastrointestinal symptoms,often attributed as the aftermath of previous inflammation,has recently become more prominent in quiescent disease.With further expected advances in anti-inflammatory treatments on the horizon,the burden of such symptoms in quiescent disease,which have been relatively neglected,is set to become an even bigger problem.In this article,we highlight the current state of research and understanding in this field,including recent developments and clinical practice guidelines on the diagnosis and management of functional gastrointestinal symptoms,such as irritable bowel syndrome and functional anorectal and pelvic floor disorders,in patients with quiescent IBD.These disorders are not only highly prevalent in these patients,they are often misdiagnosed,and are difficult to treat,with very few evidence-based therapies.Moreover,they are associated with substantial impairment in quality-of-life,considerable morbidity,and psychological distress.There is therefore an urgent need for a change in emphasis towards earlier recognition,positive diagnosis,and targeted treatment for patients with ongoing functional gastrointestinal symptoms in the absence of active IBD.This article also highlights the need for further research to develop much needed evidence-based therapies.

Prevalence of functional gastrointestinal disorders in children with celiac disease on different types of gluten-free diets

BACKGROUND Functional gastrointestinal disorders(FGIDs)are common during the pediatric age.FGIDs are not related to biochemical or structural abnormalities.However,since they have a high prevalence,several studies have evaluated an overlap between FGIDs and organic diseases.Individuals with celiac disease(CD)have been shown to be at an increased risk for functional abdominal pain,even if they adhere well to a gluten-free diet(GFD).Little information is available for the pediatric age group.The aims of our study were to evaluate the prevalence of FGIDS in CD children 1 year after diagnosis and to compare the prevalence of FGIDs in CD children on a GFD with processed foods compared with those on a GFD with natural products.AIM To assess the prevalence of FGIDs in children with CD after 1 year of follow-up and to compare the prevalence of FGIDs in children with CD on a GFD with processed foods and in children on a GFD with natural products.METHODS We recruited pediatric patients aged 1-18 years with a new CD diagnosis.Participants were randomized to two groups:Group A on a GFD with processed foods(diet 1);and group B on a GFD with natural products(diet 2).Clinical monitoring,diet assessment and the questionnaire on pediatric gastrointestinal symptoms-Rome IV version were performed at diagnosis(T0)and after 12 mo of follow-up(T1).Dietary intake was assessed using a 3-d food diary record.Data from the diaries were evaluated using WinFood nutrient analysis software.We assessed the prevalence of FGIDs at T1 and the correlation with the type of GFD.RESULTS We registered 104 CD children,with 55 patients in group A(53.0%)and 49 patients in group B(47.0%).Initially,30 of the 55(54.5%)CD children were symptomatic in group A,while 25 of 49(51.0%)were symptomatic in group B.At T1,in spite of a low or negative serology for CD,FGIDs prevalence was 10/55(18.0%)in group A and 8/49(16.3%)in group B,with no statistically significant difference between the two groups(P=0.780).At T1 the macro-and micronutrient intake was similar across the two groups with no significant differences in nutrient analysis.However,in both groups at T1 we found that a lower prevalence of FGIDs(P=0.055)was associated with an inferior caloric(odds ratio=0.99,95%confidence interval:0.99-1.00)and fat(odds ratio=0.33,95%confidence interval:0.65-0.95)intake.CONCLUSION Our results showed that CD children on a GFD have gastrointestinal symptoms with an elevated prevalence of FGIDs.Our study suggests that developing FGIDs may be linked to caloric intake and percentage of food fat,but it does not change between a GFD with processed foods or a GFD with natural products.However,long-term monitoring is required to evaluate a correlation between FGIDs and various types of GFDs.

Functional gastrointestinal disorders,mental health,genetic susceptibility,and incident chronic kidney disease

Background:Whether functional gastrointestinal disorders(FGIDs)are associated with the long-term risk of chronic kidney disease(CKD)remains unclear.We aimed to investigate the prospective association of FGIDs with CKD and examine whether mental health mediated the association.Methods:About 416,258 participants without a prior CKD diagnosis enrolled in the UK Biobank between 2006 and 2010 were included.Participants with FGIDs(including irritable bowel syndrome[IBS],dyspepsia,and other functional intestinal disorders[FIDs;mainly composed of constipation])were the exposure group,and non-FGID participants were the non-exposure group.The primary outcome was incident CKD,ascertained from hospital admission and death registry records.A Cox proportional hazard regression model was used to investigate the association between FGIDs and CKD,and the mediation analysis was performed to investigate the mediation proportions of mental health.Results:At baseline,33,156(8.0%)participants were diagnosed with FGIDs,including 21,060(5.1%),8262(2.0%),and 6437(1.6%)cases of IBS,dyspepsia,and other FIDs,respectively.During a mean follow-up period of 12.1 years,11,001(2.6%)participants developed CKD.FGIDs were significantly associated with a higher risk of incident CKD compared to the absence of FGIDs(hazard ratio[HR],1.36;95%confidence interval[CI],1.28-1.44).Similar results were observed for IBS(HR,1.27;95%CI,1.17-1.38),dyspepsia(HR,1.30;95%CI,1.17-1.44),and other FIDs(HR,1.60;95%CI,1.43-1.79).Mediation analyses suggested that the mental health score significantly mediated 9.05%of the association of FGIDs with incident CKD and 5.63-13.97%of the associations of FGID subtypes with CKD.Specifically,the positive associations of FGIDs and FGID subtypes with CKD were more pronounced in participants with a high genetic risk of CKD.Conclusion:Participants with FGIDs had a higher risk of incident CKD,which was partly explained by mental health scores and was more pronounced in those with high genetic susceptibility to CKD.

Thinking and Strategy on the Diagnosis and Treatment of Functional Gastrointestinal Disorders with Integrative Medicine

The functional gastrointestinal disorders (FGIDs) are a group of diseases mainly manifested as gastrointestinal functional disorders,including 45 kinds of different diseases,such as functional dyspepsia(FD), irritable bowel syndrome (IBS),functional constipation

Fecal calprotectin in pediatric gastrointestinal diseases:Pros and cons

BACKGROUND Fecal calprotectin is a valuable biomarker for assessing intestinal inflammation in pediatric gastrointestinal diseases.However,its role,pros,and cons in various conditions must be comprehensively elucidated.AIM To explore the role of fecal calprotectin in pediatric gastrointestinal diseases,including its advantages and limitations.METHODS A comprehensive search was conducted on PubMed,PubMed Central,Google Scholar,and other scientific research engines until February 24,2024.The review included 88 research articles,56 review articles,six metaanalyses,two systematic reviews,two consensus papers,and two letters to the editors.RESULTS Fecal calprotectin is a non-invasive marker for detecting intestinal inflammation and monitoring disease activity in pediatric conditions such as functional gastrointestinal disorders,inflammatory bowel disease,coeliac disease,coronavirus disease 2019-induced gastrointestinal disorders,gastroenteritis,and cystic fibrosis-associated intestinal pathology.However,its lack of specificity and susceptibility to various confounding factors pose challenges in interpretation.Despite these limitations,fecal calprotectin offers significant advantages in diagnosing,monitoring,and managing pediatric gastrointestinal diseases.CONCLUSION Fecal calprotectin holds promise as a valuable tool in pediatric gastroenterology,offering insights into disease activity,treatment response,and prognosis.Standardized protocols and guidelines are needed to optimize its clinical utility and mitigate interpretation challenges.Further research is warranted to address the identified limitations and enhance our understanding of fecal calprotectin in pediatric gastrointestinal diseases.

A Breakthrough Point in Integrative Medical Research:Challenge of Treating Overlapping Symptoms in Functional Gastrointestinal Disorders

Functional gastrointestinal disorders(FGIDs)are common disorders that are characterized by persistent and recurring gastrointestinal symptoms.Many patients with FGIDs have overlapping symptoms,which impaired the quality of life and ability to work of patients,and left a considerable impact on health-care systems and society.Chinese medicines(CMs)are commonly utilized by many patients with FGIDs.This article discusses the current status of diagnosis and treatment of FGIDs,the advantages and characteristics of CM treatment,and how integrated medicine can make a breakthrough in FGIDs diagnosis and treatment.

Cow’s milk-induced gastrointestinal disorders:From infancy to adulthood

Milk is related to many gastrointestinal disorders from the cradle to the grave due to the many milk ingredients that can trigger gastrointestinal discomfort and disorders.Cow’s milk protein allergy(CMPA)is the most common food allergy,especially in infancy and childhood,which may persist into adulthood.There are three main types of CMPA;immunoglobulin E(IgE)-mediated CMPA,non-IgEmediated CMPA,and mixed type.CMPA appears before the first birthday in almost all cases.Symptoms may start even during the neonatal period and can be severe enough to simulate neonatal sepsis.CMPA(often non-IgE mediated)can present with symptoms of gastroesophageal reflux,eosinophilic esophagitis,hemorrhagic gastritis,food protein-induced protein-losing enteropathy,and food protein-induced enterocolitis syndrome.Most CMPAs are benign and outgrown during childhood.CMPA is not as common in adults as in children,but when present,it is usually severe with a protracted course.Lactose intolerance is a prevalent condition characterized by the development of many symptoms related to the consumption of foods containing lactose.Lactose intolerance has four typical types:Developmental,congenital,primary,and secondary.Lactose intolerance and CMPA may be the underlying pathophysiologic mechanisms for many functional gastrointestinal disorders in children and adults.They are also common in inflammatory bowel diseases.Milk consumption may have preventive or promoter effects on cancer development.Milk may also become a source of microbial infection in humans,causing a wide array of diseases,and may help increase the prevalence of antimicrobial resistance.This editorial summarizes the common milk-related disorders and their symptoms from childhood to adulthood.

Fructose-sorbitol ingestion provokes gastrointestinal symptoms in patients with eating disorders

AIM:To evaluate gastrointestinal(GI) symptoms and breath hydrogen responses to oral fructose-sorbitol(F-S) and glucose challenges in eating disorder(ED) patients.METHODS:GI symptoms and hydrogen breath concentration were monitored in 26 female ED inpatients for 3 h,following ingestion of 50 g glucose on one day,and 25 g fructose/5 g sorbitol on the next day,after an overnight fast on each occasion.Responses to F-S were compared to those of 20 asymptomatic healthy females.RESULTS:F-S provoked GI symptoms in 15 ED patients and one healthy control(P < 0.05 ED vs control) .Only one ED patient displayed symptom provocation to glucose(P < 0.01 vs F-S response) .A greater symptom response was observed in ED patients with a body mass index(BMI) ≤ 17.5 kg/m 2 compared to those with a BMI > 17.5 kg/m 2(P < 0.01) .There were no differences in psychological scores,prevalence of functional GI disorders or breath hydrogen responses between patients with and without an F-S response.CONCLUSION:F-S,but not glucose,provokes GI symptoms in ED patients,predominantly those with low BMI.These findings are important in the dietary management of ED patients.

Attention deficit hyperactivity disorder and gastrointestinal morbidity in a large cohort of young adults

BACKGROUND Although the association of attention deficit hyperactivity disorder(ADHD)with psychiatric disorders is well known,its association with somatic diseases is unclear.Only few studies have investigated the gastrointestinal(GI)morbidity in adult patients with ADHD.AIM To measure gastrointestinal comorbidity and its burden on healthcare in young adults with ADHD.METHODS The cohort included subjects aged 17-35 years recruited to the Israel Defense Forces in 2007-2013,33380 with ADHD and 355652 without(controls).The groups were compared for functional and inflammatory conditions of the gastrointestinal tract and clinic and specialist visits for gastrointestinal symptoms/disease during service(to 2016).Findings were analyzed by generalized linear models adjusted for background variables.RESULTS Compared to controls,the ADHD group had more diagnoses of functional gastrointestinal disorders(referred to as FGID),namely,dyspepsia[odds ratio(OR):1.48,95%confidence interval(CI):1.40-1.57,P<0.001],chronic constipation(OR:1.64,95%CI:1.48-1.81,P<0.001),and irritable bowel syndrome(OR:1.67,95%CI:1.56-1.80,P<0.001)but not of organic disorders(inflammatory bowel disease,celiac disease).They had more frequent primary care visits for gastrointestinal symptoms[rate ratio(RR):1.25,95%CI:1.24-1.26,P<0.001]and referrals to gastrointestinal specialists(RR:1.96,95%CI:1.88-2.03,P<0.001)and more episodes of recurrent gastrointestinal symptoms(RR:1.29,95%CI:1.21-1.38,P<0.001).Methylphenidate use increased the risk of dyspepsia(OR:1.49,95%CI:1.28-1.73,P<0.001)and constipation(OR:1.42,95%CI:1.09-1.84,P=0.009).CONCLUSION ADHD in young adults is associated with an excess of FGID and increased use of related health services.Research is needed to determine if an integrative approach treating both conditions will benefit these patients and cut costs.

Gastrointestinal symptoms in acromegaly:A case control study

BACKGROUND Acromegaly is a chronic disease caused by a pituitary somatotroph adenoma resulting in excess secretion of growth hormone,which leads to excess secretion of Insulin like growth factor 1 from the liver,causing abnormal soft tissue growth.There is increasing awareness that diseases affecting connective tissue are associated with an increase in functional gastrointestinal symptoms.Data was collected from patients with a confirmed diagnosis of acromegaly to evaluate the intensity,variety and impact of abdominal symptoms in comparison with a control group who were healthy participants recruited from the local fracture clinic.AIM To evaluate the frequency type and burden of abdominal symptoms in acromegaly in comparison with a control group.METHODS Medical documentation of patients with a diagnosis of acromegaly treated in one tertiary medical centre between 2010 and 2017 has been analysed.Data was collected from patients with confirmed acromegaly,using the Short Form Health Survey(SF36)and Rome IV Diagnostic questionnaire for Functional Gastrointestinal Disorders in Adults(R4DQ)and compared to a sex-and agematched control group,to assess the burden of abdominal symptoms.Microsoft Excel and IBM SPSS v 25 were used for data analysis.RESULTS Fifty patients with acromegaly(24 male and 26 females;age range 23-64 years,mean 43)and 200 controls(96 male and 104 females;age range 18-84,mean 42.4)were recruited.92%(46 out of 50)of patients with acromegaly reported abdominal symptoms and 78%(39 out of 50)had at least one functional gastrointestinal disorder according to the Rome IV diagnostic criteria,compared to 16%of controls(OR>1,P<0.0001).The most commonly reported symptom was constipation(69%acromegaly vs 21%of controls OR>1,P<0.0001,95%CI:4.4–15.8).34 out of 50(68%)respondents met the criteria for functional constipation according to Rome IV.Upper gastrointestinal disorders were also more prevalent in the acromegaly group.There was no statistically significant difference in the prevalence of biliary and anorectal symptoms between the two groups.Patients in acromegaly group scored lower on the mean scores of the eight parameters of SF36 Quality of Life questionnaire(mean scores 60.04 vs 71.23,95%CI:-13.6829 to-8.6971,OR>1,P<0.001)as compared to the control group.CONCLUSION Upper and lower functional gastrointestinal tract disorders(defined by Rome IV diagnostic criteria)are significantly more prevalent in patients with acromegaly compared with healthy age and sex matched controls in our study.Functional constipation is the most commonly reported problem.Poorer quality of life may in part be attributable to the increased prevalence of abdominal symptoms.

Association between gastrointestinal symptoms and affectivity in patients with bipolar disorder

AIM To study if anxiety, depression and experience of stress are associated with gastrointestinal(GI) symptoms in patients with bipolar disorder.METHODS A total of 136 patients with bipolar disorder(mean age 49.9 years; 61% women) and 136 controls from the general population(mean age 51.0 years; 60% women) were included in the study. GI symptoms were assessed with The Gastrointestinal Symptom Rating Scale-irritable bowel syndrome(GSRS-IBS), level of anxiety and depression with The Hospital Anxiety and Depression Scale(HADS) and stress-proneness with Perceived Stress Questionnaire. Over a ten year period, all visits in primary care were retrospectively recorded in order to identify functional GI disorders.RESULTS In subjects with low total HADS-score, there were no significant differences in GI-symptoms between patients and controls(GSRS-IBS 7.0 vs 6.5, P = 0.513). In the patients with bipolar disorder there were significant correlations between all GSRS and HADS subscores for all symptom clusters except for "constipation" and "reflux". Factors associated to GI symptoms in the patient group were female sex(adjusted OR = 2.37, 95%CI: 1.07-5.24) and high HADS-Depression score(adjusted OR = 3.64, 95%CI: 1.07-12.4). These patients had also significantly more visits for IBS than patients with low HADS-Depression scores(29% vs 8%, P = 0.008). However, there was no significant differences in consulting behaviour for functional GI disorders between patients and controls(25% vs 17%, P = 0.108).CONCLUSION Female patients and patients with high HADS depression score reported significantly more GI symptoms, whereas patients with low HADS scores did not differ from control subjects.

Enduring association between irritable bowel syndrome and war trauma during the Nicaragua civil war period:A population-based study

BACKGROUND Psychosocial and physical trauma are known risk factors for irritable bowel syndrome(IBS),including in war veterans,whereas war exposure in civilians is unclear.Nicaragua experienced two wars,1970-1990:The Sandinistas Revolution(1970s)and The Contra War(1980s).Our aim was to investigate the role of exposure to war trauma in the subsequent development of IBS in the context of an established health surveillance system(11000 households).AIM To investigate in a civilian population the relationship between exposure to war trauma and events and the subsequent development of IBS in the context of an established public health and demographic surveillance system in western Nicaragua.METHODS We conducted a nested population-based,cross-sectional study focused on functional gastrointestinal disorders based on Rome II criteria.1617 adults were randomly selected.The Spanish Rome II Modular Questionnaire and Harvard Trauma Questionnaire were validated in Nicaragua.War exposure was assessed with 10 measures of direct and indirect war trauma and post-war effects.Multiple exposures were defined by≥3 measures.RESULTS The prevalence of IBS was 15.2%[Female(F)17.1%,Male(M)12.0%],war exposure 19.3%(F 9.3%,M 36.7%),and post-traumatic stress disorder(PTSD)5.6%(F 6.4%,M 4.3%).Significant associations with IBS in the civilian population were observed(adjusted by gender,age,socioeconomic status,education):physical and psychological abuse[adjusted odds ratio(aOR):2.25;95%confidence interval:1.1-4.5],witnessed execution(aOR:2.4;1.1-5.2),family member death(aOR:2.2;1.2-4.2),and multiple exposures(aOR:2.7;1.4-5.1).PTSD was independently associated with IBS(aOR:2.6;1.2-5.7).CONCLUSION An enduring association was observed in the Nicaragua civilian population between specific civil war-related events and subsequent IBS.Civilian populations in regions with extended armed conflict may warrant provider education and targeted interventions for patients.

Associations between irritable bowel syndrome and non-alcoholic fatty liver disease:A systematic review

BACKGROUND Irritable bowel syndrome(IBS)is associated with obesity and metabolic syndrome.IBS and non-alcoholic fatty liver disease(NAFLD)are highly prevalent entities worldwide and may share similar mechanisms including gut dysbiosis,impaired intestinal mucosal barrier and immune system activation.AIM To systematically review their association according to the Preferred Reporting Items for Systemic Review and Meta-analyses guidelines.METHODS PubMed,EMBASE and Cochrane Database of Systematic Reviews were searched for relevant papers.Manual searches were also performed.RESULTS Six studies were included.Both IBS and NAFLD subjects had significantly more metabolic risk factors like hypertension,obesity,dyslipidaemia and diabetes.Our review showed that 23.2%to 29.4%of NAFLD patients had IBS.IBS was significantly higher in NAFLD patients compared with patients without NAFLD(23.2%vs 12.5%,P<0.01).A higher proportion of IBS patients had NAFLD(65.8%to 74.0%).IBS patients were three times more likely to have NAFLD compared with non-IBS patients(P<0.001).Two studies showed a significant correlation between the severity of IBS and NAFLD.The proportion of NAFLD subjects with IBS increased with NAFLD severity.CONCLUSION Further prospective studies are warranted to evaluate the relationship and shared pathways between IBS and NAFLD,potentially leading to the development of future therapeutics.

Clinical observation on functional gastrointestinal motility disorder of postoperation of gastrointestinal tumor treated with electroacupuncture

Objective To observe the effects on functional gastrointestinal motility disorder of postoperation of gastrointestinal tumor treated with electroacupuncture. Methods Twenty-nine cases of functional gastrointestinal motility disorder of postoperation of gastrointestinal tumor were randomized into electroacupuncture group （19 cases） and control group （10 cases）. In electroacupuncture group, routine treatment after gastrointestinal operation and electroacupucture treatment were applied, Zusanli （足三里 ST 36）, Shangjuxu （上巨虚 ST 37）, Xiajuxu （下巨虚 ST 39） and Hegu （合谷 LI 4） were applied with electroacupuncture; in control group, the routine treatment after gastrointestinal operation was only applied. Anus exhaust, defecation, abdominal distension, stomachache, amount of gastrointestinal decompression drainage and changes of borborygmus were observed in two groups. Results Anus exhaust, defecation, abdominal distension, stomachache, amount of gastrointestinal decompression drainage and changes of borborygmus were relieved in two groups; and the effects of abdominal distension, anus exhaust, defecation, amount of gastrointestinal decompression drainage and borborygmus in electroacupuncture group were superior to those in control group （all P〈0.05）. Conclusion For the functional gastrointestinal motility disorder of postoperation of gastrointestinal tumor, the theraputic effect of electroacupuncture combined with routine treatment after operation is better than the routine treatment after operation.

A randomized controlled trial of imipramine in patients with irritable bowel syndrome

AIM: To study the efficacy of low-dose imipramine in relieving symptoms associated with the irritable bowel syndrome (IBS). METHODS: A randomized, double-blind trial of 25 mg imipramine vs matched placebo for 12 wk was performed. Doubling the dose was allowed once at week 2 in case of an unsatisfactory early response. Primary efficacy variables were subjective global symptom relief and quality of life (QoL) using SF-36 at week 12. RESULTS: One hundred and seven patients were enrolled by advertisement or referral by general practitioners and 56 (31 imipramine: 25 placebo) completed the 16-wk study. Baseline characteristics were comparable. A high overall dropout rate was noted in the imipramine and placebo arms (47.5% vs 47.9%, P > 0.05), a mean of 25.0 and 37.4 d from enrollment, respectively (P < 0.05). At the end of 12 wk, there was a significant difference in global symptom relief with imipramine over placebo (per-protocol: 80.6% vs48.0%, P = 0.01) and a trend on intent-to-treat (ITT) analysis (42.4% vs 25.0%, P = 0.06). This improvement was evident early and persisted to week 16 (P = 0.024 and 0.053 by per-protocol and ITT analyses, respectively). Mean cumulative and componentspecific SF-36 scores improved in the imipramine group only (per-protocol, P < 0.01). Drug-related adverse events leading to patient dropout were more common in the imipramine group (25.4% vs 12.5%, P > 0.05). CONCLUSION: Imipramine may be effective in the treatment of IBS patients and is associated with improved QoL. Careful patient selection, initiation of a low dose with gradual escalation and monitoring for side effects may result in an improved therapeutic response.

Sphincter of Oddi dysfunction:Psychosocial distress correlates with manometric dyskinesia but not stenosis

AIM:To compare postcholecystectomy patients with Sphincter of Oddi(SO)dyskinesia and those with normal SO motility to determine the psychosocial distress,gender and objective clinical correlates of dyskinesia,and contrast these findings with comparisons between SO stenosis and normal SO motility.METHODS:Within a cohort of seventy-two consecutive postcholecystectomy patients with suspected SO dysfunction,manometric assessment identified subgroups with SO dyskinesia(n=33),SO stenosis(n=18)and normal SO motility(n=21).Each patient was categorized in terms of Milwaukee Type,sociodemographic status and the severity of stress-coping experiences.RESULTS:Logistic regression revealed that in combination certain psychological,sociodemographic and clinical variables significantly differentiated SO dyskinesia,but not SO stenosis,from normal SO function.Levels of psychosocial stress and of coping with this stress(i.e.anger suppressed more frequently and the use of significantly more psychological coping strategies)were highest among patients with SO dyskinesia,especially women.Higher levels of neuroticism(the tendency to stressproneness)further increased the likelihood of SO dyskinesia.CONCLUSION:A motility disturbance related to psychosocial distress may help to explain the finding of SO dyskinesia in some postcholecystectomy patients.

Epidemiological and clinical perspectives on irritable bowel syndrome in India, Bangladesh and Malaysia: A review

Irritable bowel syndrome(IBS) is a chronic gastrointestinal disorder, common in clinic and in the community. It has a significant impact on both society and patients' quality of life. The epidemiology, clinical presentation, and management of IBS may vary in different geographical regions due to differences in diet, gastrointestinal infection, socio-cultural and psychosocial factors, religious and illness beliefs, symptom perception and reporting. Although previous reviews and consensus reports on IBS in Asia have been published, Asia is quite diverse socio-demographically. In this context, India, Bangladesh and Malaysia share some similarities, including:(1) large proportion of the population living in rural areas;(2) rapid development and associated lifestyle changes in urban areas; and(3) dietary, cultural and religious practices. The present review explores the clinical and epidemiological data on IBS from these three major nations in South and South-East Asia. In-depth review of the literature revealed important differences between IBS in the East, as revealed by studies from these three countries, and the West; these include a predominantly rural profile, differences in bowel habit and symptom profile, raising concern with regards to diagnostic criteria and subtyping of IBS, higher dietary fiber consumption, frequent lactose malabsorption, parasitosis, and possible overlap between post-infectious IBS and tropical sprue. Moreover, the current perception on difference in prevalence of the disorder in these countries, as compared to the West, might be related to variation in survey methods.
