Background: Irritable bowel syndrome is a diagnosis of exclusion. It is a functional bowel disorder characterized by chronic abdominal pain, discomfort, bloating, and alteration of bowel habits in the absence of any detectable organic cause."Tu than hoan" is a traditional remedy applied for the treatment of syndromes of traditional medicine which have the similar characteristics to irritable bowel syndrome of diarrhea state of modern medicine. Objectives: The study had two purposes: (1)To evaluate the therapeutic effects of the remedy on the clinical symptoms of patients with irritable bowel syndrome of diarrhea state comparing with Duspatalin; (2)To evaluate the side effects of the remedy. Subjects and method:162 patients diagnosed with irritable bowel syndrome of diarrhea state were treated at Bach Mai hospital from March to August 2005. They divided into 2 groups, the control group included 77 patients and the study group included 85 patients. : clinical test, comparing with controls. Results: 80% of patients recovered from diarrhea; 82.4% of patients with defecation returned to normal; 93.6% stopped mucous feces; 76.5% stopped bellyache. Good therapeutic effect was 61.2% (p < 0.05). Conclusions: Tu than hoan had good therapeutic effects in the treatment of irritable bowel syndrome of diarrhea state. None of patients had to discontinue the medicine due to side effects. \r\n', u' \r\n', u'

2.The Pathophysiology of Irritable Bowel Syndrome: Inflammation and Motor Disorder.
The Korean Journal of Gastroenterology 2006;47(2):101-110
Irritable bowel sydrome (IBS) is one of the most common disorders and a heterogeneous condition in view of symptoms and underlying mechanisms. Though underlying causes of pathophysiologic changes remain unclear, low grade mucosal inflammation and abnormal intestinal motility are accepted mechanisms which alter gut function and generate symptoms of IBS. First, before 1980s, abnormal colonic and rectal motor functions were regarded as the main pathophysiology of IBS, but only 25-75% of IBS patients have apparent motor abnormalities which differ from the motor functions in normal controls. So, various gastrointestinal motility tests were not indicated for the diagnosis of IBS. The high-amplitude propagating contractions of colon in IBS patients may be related to the visceral pain perception. Second, the low grade mucosal inflammation may be involved in the pathophysiology of visceral hypersensitivity. Post infectious IBS (PI-IBS) occupied 6-17% of the total IBS and some previous prospective studies reported that 7-33% of acute bacterial enteritis patients developed IBS after 6-12 months of infection. The relative risk of IBS in the gastroenteritis cohort was 11.9 and the strongest risk factor is the duration of diarrhea. After enteritis event, the increased number of immunocytes, mast cells and large amount of lymphocytes infiltration were revealed in mucosa and enteric nervous system of the gut. Beside the inflammatory cells, enterochromaffin cells, cytokines and inducible nitric oxide may be related to the pathophysiologic mechanism of PI-IBS. Lastly, the abnormalities in the gastrointestinal autonomic nervous system can induce constipation or motor disorders, but further research should elucidate it.

BACKGROUND/AIMS: Capsule endoscopy is a diagnostic method for evaluating the small bowel lumen and can detect undiagnosed lesions. The aim of this study was to evaluate the diagnostic yield and clinical impact of capsule endoscopy in patients with refractory diarrhea-predominant irritable bowel syndrome and functional abdominal pain. METHODS: This study involved a retrospective analysis of prospectively collected data, maintained in a database. Patients with refractory diarrhea-predominant irritable bowel syndrome and functional abdominal pain within the period of March 2012 to March 2014 were included. Capsule endoscopy was used to detect small bowel pathologies in both groups. RESULTS: Sixty-five patients (53.8% female) fulfilled the inclusion criteria and had a mean (±standard deviation) age of 50.9±15.9 years. Clinically significant lesions were detected via capsule endoscopy in 32.5% of the patients in the abdominal pain group and 54.5% of the patients in the diarrhea group. Overall, 48% of patients had small bowel pathologies detected during the capsule endoscopy study. Inflammatory lesions and villous atrophy were the most frequent lesions identified in 16.9% and 15.3% of patients in the abdominal pain and the diarrhea groups, respectively. CONCLUSIONS: Routine use of capsule endoscopy in patients with irritable bowel syndrome should not be recommended. However, in patients with refractory conditions, capsule endoscopy may identify abnormalities.

4.Natural History and Overlap of Functional Gastrointestinal Disorders.
The Korean Journal of Gastroenterology 2012;60(6):345-348
Functional gastrointestinal (GI) disorders are common in the general population. Based on the Rome III classification, these disorders are mutually exclusive disorders keeping the homogeneity of each functional GI disorder in research area. In contrast, many population and clinical studies have reported a considerably high rate of overlap between functional GI disorders. The overlap of functional GI disorders over other intestinal diseases might simply occur by chance due to a highly prevalent disorder. Moreover, functional GI disorders is considered a chronic stable disorder that may wax and wane for several years. However, a recent study about the natural history of functional GI disorders showed substantial transition among functional GI disorders over time. The natural history of functional GI disorders with overlapping other functional GI disorders are still in infancy and better understanding of these will be important in determining the efficacy of future therapeutic interventions.

Mast cells (MC) may be one factor influencing the response of visceral afferent nerves to mechanical and chemical stimuli. The aim of this study was to evaluate the degree of infiltration and activity of colonic MC in irritable bowel syndrome (IBS). Biopsy specimens were obtained from the cecum and rectum of 14 diarrhea predominant IBS and 14 normal controls. Electron microscopy was used to determine the number of intact and degranulated colonic MC and to quantify these separately according to the distance between MC and enteric nerves. An increased number of MC in both cecum and rectum in the IBS group in comparison with the control group was demonstrated (p<0.05). Activated MC in close proximity to enteric nerves were significantly increased in both cecum and rectum of the IBS group compared to control group (p<0.005). In addition, activated MC were significantly increased in close proximity to the nerves compared to those in the remote area in both cecum and rectum of the IBS group (p<0.0001). MC were significantly increased and activated in both cecum and rectum of the IBS group compared to controls. MC may play a role in the gut sensory hypersensitivity of IBS.

Functional gastrointestinal disorders are more common in women in relation to the fluctuations of female sex hormones. We tried to know the gender-related differences in the prevalence of irritable bowel syndrome and gastrointestinal symptoms according to the menstrual phase. A total of 253 women before menopause and 252 men below age 50 were examined by a gastroenterologist after completing the questionnaire. Blood tests, endoscopic procedures, and imaging studies were done, if needed. Women were subclassified into three groups according to their menst- ruation period; menstrual phase, proliferative phase, and secretory phase. Finally, 179 men and 193 women were analyzed. Irritable bowel syndrome was more frequently noticed in women than in men (p=0.01). The diarrhea-dominant type was more common in men, while constipation-dominant or alternating types were more common in women (p<0.001). Of 193 women, there was no significant difference in their gastrointestinal symptoms according to their menstrual phase. Regardless of the menstrual phase, gastrointestinal symptoms are more frequent in women. Physicians should consider different symptomatic manifestations between men and women should be considered when evaluating functional gastrointestinal disorders.

OBJECTIVETo investigate the presence of tight junction (TJ) changes of the intestinal mucosa, and elucidate the possible mechanism for changes in bowel evacuation in patients with irritable bowel syndrome (IBS).
METHODSIn 10 normal control subjects, 10 patients with constipation predominant IBS (C-IBS) and 10 with diarrhea predominant IBS (D-IBS), biopsies were taken from the terminal ileum and ascending colon. Lanthanum nitrate tracing electron microscope and cytochemical technique were employed to observe TJ changes in the intestinal mucosa.
RESULTSLike the control subjects, C-IBS patients had normal TJ structure in the intestinal mucosa, whereas D-IBS patients exhibited some abnormalities in TJ structure either in their terminal ileum (7 in 10) or ascending colon (8 in 10), revealed by TJ gap widening with lanthanum nitrate extravasation into the surrounding tissue. Such changes were also observed in 3 of the 4 patients with a history of acute infectious diarrhea.
CONCLUSIONThe changes in the intestinal mucosal TJ structure and function might contribute to altered bowel evacuation in patients with irritable bowel syndrome.

9.Current Issues on Irritable Bowel Syndrome: Diet and Irritable Bowel Syndrome.
Jeong Hwan KIM ; In Kyung SUNG
The Korean Journal of Gastroenterology 2014;64(3):142-147
Irritable bowel syndrome (IBS) is one of the most prevalent functional gastrointestinal disorders. It is a multifactorial disorder with its pathogenesis attributed to abnormal gastrointestinal motility, low-grade inflammation, visceral hypersensitivity, communication in the gut-brain axis, and so on. Traditionally, IBS has been treated with diet and lifestyle modification, fiber supplementation, psychological therapy, and pharmacological treatment. Carbohydrates are intermingled with a wide range of regularly consumed food including grains such as rye and wheat, vegetables, fruits, and legumes. Short-chain carbohydrates that are poorly absorbed exert osmotic effects in the intestinal lumen increasing its water volume, and are rapidly fermented by bacteria with consequent gas production. These effects may be the basis for the induction of most of the gastrointestinal symptoms. This has led to the use of lactose-free diets in those with lactose intolerance and of fructose-reduced diets for fructose malabsorption. As all poorly absorbed short-chain carbohydrates have similar and additive effects in the intestine, a concept has been developed to regard them collectively as FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) and to evaluate a dietary approach that restricts them all. Based on the observational and comparative studies, and randomized-controlled trials, FODMAPs have been shown to trigger gastrointestinal symptoms in patients with IBS. Food choice via the low FODMAPs and potentially other dietary strategies is now a realistic and efficacious therapeutic approach for managing symptoms of IBS.

Inflammatory polyposis of the colon is rare portion of the colon polyp entity. We experienced three patieats who suffered from colitis of unknown'etiology and discovered membranous retkular with/ without filiform polyp in the distal sigmoid colon of the them. Case 1, 56-year-old female, combined with basaloid cercinoma of the rectal canal that confirmed by pathology after abdominoperineal resection. So we obtained specimen of inflammtory polyp end tried to evaluate the mechanism of it. We found healed ulcer under the mucosal bridge. Case 2. 55-year-old male, had been suffered from irritable bowel syndrome. Prior to visit outpatient clinic, he complained tenesmus with diarrhea for a week. Inflammatory polyp was discovered by colonoacopy but his symptoms relieved by tranqulizers only. Case 3. 57-year-old male, has been a good health. He undertook colonoscopy for routine check thst revealed membranous reticular with filiform inflammatory polyp from distal sigmoid colon to hepatic flexure. Such shape of inflammatory polyp was not documented in Korea, so we reported three cases of it with review of the literature.
