The irritable bowel syndrome (IBS) is a very common condition in gastroenterology clinics, but yet it is one of the pooly understood. A international working team in Rome, 1988, proposed that IBS is a functional intestinal disorder with chronic or recurrent gastrointestinal symptoms without structural or biochemical abnormalities. IBS was sub-classified into 3 groups; abdominal pain as the prominent feature with diarrhea, with constipation, with both while painless diarrhea and simple constipation without pain were excluded from IBS. There is a lot of data suggesting that IBS has a gut dysmotility, which is influenced by many stimuli (food, hormone, drug, menses, mechanical dilatation), including psychological stress. Moreover, currently available evidences implicate that IBS is a more generalized disorder of smooth muscle function not only in the intestine but also outside of the intestine.

In irritable bowel syndrome (IBS), motility disturbances occur from the upper gastrointestinal tract to the distal colon, where regulatory peptides have a wide-spread distribution. Studies on basal and postprandial plasma levels of different gut hormones show that VIP, CCK, and motilin may be closely related to the symptoms including abdominal pain, diarrhea and constipation. In addition, peptide YY and NPY have effects on absorption in the intestine, and some opioid peptides exert actions on colonic motility in IBS patients. Recent studies revealed that gall bladder in IBS has an abnormal sensitivity to CCK-8, indicating that IBS patients has an generalized abnormality of the smooth muscle of the digestive tract. Gut hormones, which act as hormones, neurotransmitters and neuromodulators depending on their releasing site, may therefore play an important role in IBS patients.

The irritable bowel syndrome (IBS) is characterized by alteration in bowel habits (i.e., constipation and/or diarrhea) and abdominal pain, and is most common gastrointestinal disorder in adults. The recurrent abdominal pain (RAP) in children is similar to IBS in adults except bowel habits, but there is no settled conception of IBS in children. In our department, diagnosis of pediatric IBS will be made if the child has; #1 functional gastrointestinal disorders without organic diseases, #2 abdominal pain and other gastrointestinal symptoms continuing more than 3 weeks, #3 psychogenic background factors. We experienced 63 cases of IBS (23.5% in all 268 cases) from April 1990 to March 1992 at our pediatric digestive outpatient clinic. They ranged from 4 to 15 years old and about 60% of them were elder than 13 years old. Psychogenic factors were usually related to environment of school life and home. Careful history taking and routine examination were most important for the diagnostic approach. Management of this disease included counseling and drug therapy. Almost all cases reached much better condition 1 to 6 weeks after the therapy started. The combination therapy with psychologist was required in a few cases.

We studied seventy patients, 23 males and 47 females with irritable bowel syndrome in adolescence aged 13-19 yrs, who visited the department of psychosomatic medicine in Takano Hospital during about six year period of April, 1986-July, 1992. Takano Hospital is a coloproctological center in Kumamoto. In the clinical pattern of adolescent patients with irritable bowel syndrome the "gas" pattern was dominant (51.4%). Patients with the gas pattern have severe symptoms of flatus, fullness, rumbling sound and abdominal pain as well as bowel dysfunction, constipation and diarrhea in a classroom. Next, the diarrheal pattern occurred in 20.0%. Diarrheal patients complained of frequent bowel movements and retention feelings before attending school. Recurrent abdominal pain-like pattern was found in 7.1% patients. Clinical symptoms in the adolescent patients seem to derived from a mental tension and stress in a close classroom or before attending school. Many adolescenct patients (67.1%) with irritable bowel syndrome are embarrassed in school-maladjustment; leaving class early, late coming, a long absence, and a withdrawal.

In the treatment of IBS best results could be obtained by implementing a comprehensive program for the patients. This might include a through examination, an explanation of the condition to the patients, psychologic managements, and correction of any bad habits, as well as drug therapy. The aim of drug therapy of IBS is the relief of the symptoms: such as abdominal pain, disturbed bowel function, anxiety or depression. As there is no drug which is effective in relieving the entire range of symptoms, drug should be chosen according to specific symptoms. Tranquilizers and antispasmodics may be the most commonly used drugs, however their efficacy is limited. To postprandial pain antispasmodics or trimebutine are most effective when prescribed before meal. Antidepressant are beneficial for the depressive state. Bulking agents are preferable mainly in relieving constipation, and loperamide is effective in treating diarrhea.

Irritable bowel syndrome (IBS) is defined as a functional bowel disorder in which abdominal pain is associated with defecation or a change in bowel habit, and with features of disordered defecation and distension. The irritable bowel syndrome occurs in 10 to 20% of people worldwide and is very commonly encountered in clinical practice. This has encouraged the pharmaceutical industry to search for effective drug therapy. So far, a universally effective agent has not been found, and since this is a chronic, benign disorder, beginning in youth, long term drug use should be avoided. Nevertheless, if a specific IBS symptom, such as constipation or abdominal pain dominates, a specific drug may be helpful. However, tests and treatment should be minimised or even avoided in order to do no harm. A largely nonpharmaceutical approach to IBS should be taken. This approach employs drugs sparingly and then only targeted at specific and resistant symptoms.

Octylonium bromide (OB) is a drug with spasmolytic properties acting selectively on the smooth muscle of the gastrointestinal tract by interfering with calcium mobilization from extra- and intra-cellular deposits. The etiopathogenetic implications of a psychosomatic nature of the irritable bowel syndrome amply justify the use of a spasmolytic (OB) with a benzodiazepine. In our study, we compared the combination OB + DZ (20 mg + 2 mg) T.I.D. versus OB alone (20 mg) in 30 patients suffering from irritable bowel syndrome. The double-blind study lasting 3 weeks was aimed at evaluating gastrointestinal symptoms (bowel motions, aspect of faeces, abdominal pain, pre-evacuation pain, bloating) during the three days preceding the study and during the last five days of treatment, as well as the anxiogenic situation as assessed by the STAI scale (State Tract Anxiety Inventory) before and at the end of the treatment period. The results obtained showed that both treatments considerably reduced gastrointestinal symptoms even though OB alone did not appear to be equally effective and the anxiety component was significantly reduced only by treatment with the combination. The absence of side effects and the perfect tolerability of both treatments showed the OB + D combination T.I.D. to be the treatment of choice for patients suffering from irritable bowel syndrome.

Serotoninergic innervation may contribute to the control of colonic motility and to visceral sensation from the large bowel. Indeed, ondansetron hydrochloride, a selective 5-hydroxytryptamine type 3 receptor antagonist, has been shown to slow colonic transit in healthy volunteers. Thus, we wished to determine whether 5-hydroxytryptamine type 3 receptor blockade slows colonic and small bowel transit in patients with diarrhea-predominant irritable bowel syndrome (IBS) and whether symptoms would be ameliorated with drug therapy. Of 14 patients with well-established IBS who entered a randomized, double-blind, placebo-controlled crossover pilot trial of 4 weeks of treatment with ondansetron, 16 mg three times daily, 11 completed the study. A minimal "washout period" of 4 weeks (median, 7 weeks) separated the two phases of the trial because patients were required to have similar symptoms before both periods of the study. Colonic transit tended to be longer during drug therapy than during the placebo trial, but this difference was not significant. Small intestinal transit and orocecal transit were unchanged by the drug. The integrated and peak postprandial increases in neurotensin, peptide YY, and human pancreatic polypeptide in serum were not significantly different in the drug and placebo periods. After treatment with ondansetron, stool consistency improved significantly; however, stool frequency, stool weight, abdominal pain, and the symptom criteria for IBS were not significantly altered by the drug. The results of this pilot study suggest that the motor effects expected with 5-hydroxytryptamine type 3 receptor blockade (namely, slowed colonic transit) may be diminished in some patients with IBS. The subjective improvement in stool consistency may reflect changes in the perception of defecation.(ABSTRACT TRUNCATED AT 250 WORDS)

Motility-like dyspepsia, a clinical subgroup of functional dyspepsia, refers to the cluster of symptoms which suggests an underlying motility disturbance of the upper gut. Characteristic symptoms, in addition to upper abdominal pain or discomfort, are nausea, vomiting, early satiety, anorexia, postprandial abdominal bloating and excessive repetitive postprandial belching. Patients with concomitant symptoms of irritable bowel syndrome are currently excluded from this clinical entity. Delayed gastric emptying of solids and/or liquids, postprandial antral hypomotility and antroduodenal incoordination, gastric myoelectrical arrhythmias and dysfunction of visceral afferents are the major alterations in upper gut sensorimotor activity which have been described. An empirical trial of medical therapy is warranted if there are no "alarm" symptoms at presentation. If symptoms are not relieved after 2-4 weeks, then investigations of the upper gastrointestinal tract, preferably by endoscopy, to exclude the presence of organic disease, is advisable. Management approaches are then reassurance, dietary manipulations and attention to psychosocial aspects. Prokinetic agents appear to be useful as short-term medical therapy in some patients, but optimum long-term treatment strategies, including the use of medications which may improve a diminished tolerance to gut distension, are not established.

We investigated the effect of octylonium bromide on a number of symptoms and functional aspects of the irritable bowel syndrome. Seventy-two patients complaining mainly of abdominal pain were studied in a double-blind trial (octylonium bromide 40 mg tid for 4 weeks or placebo). Clinical parameters were: abdominal pain, bloating and bowel frequency. Sigmoid manometry with simultaneous recording of the thresholds for distension and/or pain upon graded inflation of an endoluminal balloon was performed before and at the end of treatment. In contrast to placebo, octylonium bromide significantly reduced pain and bloating, and significantly increased (p < 0.02) the pain threshold throughout the treatment period. However, comparison with the placebo group failed to show any relevant differences. Neither treatment influenced the frequency of bowel movement. Sigmoid motility during distension was significantly reduced after octylonium bromide (p < 0.05), but it did not change after placebo. In conclusion, octylonium bromide is capable of reducing symptoms and motor reactivity of the sigmoid in patients with irritable bowel syndrome.
