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.

Distal colonic motor activity was measured in 12 control subjects and seven constipation-predominant irritable bowel syndrome patients to examine the effects of intravenous administration of cholecystokinin. In the basal state, no significant motility differences were noted between these two groups. Following the intravenous administration of the hormone cholecystokinin, a statistically significant reduction in colonic motility in control subjects and a non-significant decrease in motility in irritable bowel syndrome patients was seen. Our results do not suggest an exaggeration of the colonic motor response to cholecystokinin occurs in irritable bowel syndrome.

Previous research has demonstrated a number of conditions, such as sleep disturbance, fatigue, depression, spastic colon and mitral valve prolapse, associated with fibromyalgia. The present report describes additional symptoms and medical conditions that appear to be associated with the syndrome based on a survey of 554 individuals with fibromyalgia compared with a group of 169 controls. Individuals with fibromyalgia self report a greater incidence of bursitis, chondromalacia, constipation, diarrhea, temporomandibular joint dysfunction, vertigo, sinus and thyroid problems. Symptomatic complaints found statistically more prevalent in fibromyalgia patients included concentration problems, sensory symptoms, swollen glands and tinnitus. Other associations occurring with significant increased frequency were chronic cough, coccygeal and pelvic pain, tachycardia and weakness. Our previous report on inheritance patterns in fibromyalgia was reaffirmed with 12% reporting symptomatic children and 25% reporting symptomatic parents. Of the respondents, 70% noted that their symptoms were aggravated by noise, lights, stress, posture and weather.

In this article, we review the currently available techniques for measuring small intestinal and colonic transit. In addition, we describe the characteristics of an ideal test that provided the rationale for the development and validation of a gastrointestinal and colonic transit test at the Mayo Clinic. This new technique assesses regional transit of solid radiolabeled particles of the same size through the entire digestive tract and provides further insights into motor physiologic processes of the gut. By means of a delayed-release methacrylate-coated capsule, isotopically labeled pellets are delivered to the colon as a single bolus; thereby, dispersion of isotope throughout the small bowel is avoided because of the gradual emptying of chyme from the stomach. Similar pellets labeled with a different isotope can be used to assess gastric and small bowel transit. These new methods for measuring transit have also led to insights into the pathogenesis of unexplained gastrointestinal symptoms and disease states. Thus, we demonstrated that in healthy subjects, ileocolonic transfer of chyme occurs in boluses; this transfer is impaired in patients with myopathic pseudo-obstruction. The emptying rate of the proximal colon is an important determinant of the pathophysiologic features of colonic disease; thus, colonic transit is delayed in cases of severe idiopathic constipation. In contrast, rapid emptying of the proximal colon influences stool weight in diarrhea-predominant irritable bowel syndrome. An integrated approach for studying gastric, small bowel, and colonic transit by using the same radiolabeled particle provides a useful, clinically applicable method for evaluating gastrointestinal symptoms and for measuring motor function of the entire digestive tract without need for intubation; cost and radiation exposure are acceptable.

Irritable bowel syndrome, constipation, and diarrhea may complicate a pregnancy. Complaints of IBS and constipation may be managed by nonpharmaceutical methods. A careful history should be conducted to determine whether these complaints are of an acute or a long-standing nature. Conservative treatment of IBS is recommended and may include stool-bulking agents, a high-fiber diet, elimination of offensive foods, and the behavioral treatment of passive muscle relaxation, biofeedback or supportive psychotherapy. Constipation is generally self-limiting. It also may be treated conservatively with stool-bulking agents, increases in dietary fiber, and the addition of pelvic muscle exercises, preferably using electromyographic biofeedback. Laxatives should be used judiciously (Table 1). Diarrhea is caused most often by infectious agents in pregnancy but may also be from food poisoning or a viral disease. Infectious diarrhea may be treated by mild antidiarrheal agents and safe antibiotics. Fluid replacement is the mainstay of treatment, and care should be taken, remembering that the treatment involves two patients. These complaints can generally be managed conservatively, but persistent cases should be investigated as in a nonpregnant patient.

Behavioral research in gastroenterology has grown exponentially over the last decade. Controlled studies demonstrate that psychotherapy, stress management, and hypnosis are effective for irritable bowel syndrome; and behavioral treatments are preferred over medical management for some types of fecal incontinence and vomiting. For peptic ulcer disease, interest in behavioral treatments has declined. However, a new syndrome, functional dyspepsia, is now recognized, in which ulcerlike symptoms occur without ulcer and frequently in association with psychological symptoms. For inflammatory bowel disease, stress management training has produced inconsistent outcomes. Newly recognized disorders for which behavioral treatments are needed include constipation associated with inability to relax the pelvic floor muscles during defecation, functional rectal pain (proctalgia), noncardiac chest pain, and aerophagia (excessive air swallowing).

Almost all functions of the gastrointestinal tract have been shown to be under central nervous control and to respond to environmental factors such as stress. It is, therefore, not surprising that disturbed gastrointestinal functions may be altered through psychological therapy approaches. For motor dysfunctions of the esophagus and functional dyspepsia, there is a lack of behavioral therapy studies, while controlled studies utilizing relaxation techniques, stress management strategies and anxiety treatment have been shown to improve symptoms and prevent recurrence in reflux esophagitis and peptic ulcer disease despite the wide use of effective medication. Most studies have treated patients with symptoms of the irritable bowel syndrome: This approach usually combined conventional medical treatment with psychotherapy. Psychological management usually consisted of relaxation training, stress management and patient information. Additional behavioral modification, e.g. of eating and defecation behavior, is superior to pharmacological and dietary management alone. The role of biofeedback therapy in these patients remains to be clarified in the future. It is, however, therapy of choice in some patients with constipation due to spastic pelvic floor syndrome and in fecal incontinence, if the external anal sphincter is insufficient to maintain continence. There ist a systematic lack of treatment opportunities as compared to the number of patients seeking health care for functional bowel disorders.

Biofeedback has had a greater impact on gastroenterology than on any other medical subspecialty. Biofeedback is the treatment of choice for many of the most common types of fecal incontinence, and preliminary studies suggest that it is likely to become a preferred method for treating patients with constipation related to inability to relax the striated pelvic floor muscles during defecation. This dysfunction may account for up to 50% of patients with chronic constipation. Thermal biofeedback forms part of a multicomponent behavioral treatment for irritable bowel syndrome that is reported to be effective, and other promising applications of biofeedback for gastrointestinal disorders are under investigation.
