This study assessed the value of common surface coil magnetic resonance imaging (MRI) in patients with evacuatory disorders including fecal incontinence and constipation. These findings were then compared with those from other standard physiological examinations and/or surgical findings. From July 1996 to June 1997, 14 consecutive patients underwent surface coil MRI for evaluation of either fecal incontinence (n=5) or constipation (n=9). In patients with incontinence we compared the findings from endoanal ultrasound (EAUS), anal MRI, and surgery regarding morphopathological findings of the internal and external anal sphincter components. In constipated patients the findings of videoprography and dynamic pelvic MRI were compared regarding the presence of rectocele, rectoanal intussusception, and sigmoidocele as well as the measurements of anorectal angle and perineal descent. The five incontinent patients were all women, with a median age of 67 years (range 43-77). EAUS revealed an anterior sphincter defect in two patients, a posterior defect in one, and normal anal sphincter images in two. Surgical findings confirmed an anterior external anal sphincter scar in two patients, an internal anal sphincter defect in one, and an anatomically normal anal sphincter in two. In one patient, although anal MRI showed posterior external anal sphincter defect, EAUS and surgery revealed normal external anal sphincter appearance. The accuracy rate between EAUS and anal MRI was only 20%, that between surgery and anal MRI 40%, and that between surgery and EAUS 80%. Thus EAUS was more accurate than anal MRI in incontinent patients. The nine constipated patients were all women, with a mean age

Functional gastrointestinal disease is believed to be very common, but reports of its prevalence have not usually evaluated random community samples, and validated questionnaires have not been used to elicit symptoms. The prevalence of specific colonic symptoms and the irritable bowel syndrome among representative middle-aged whites was determined from a defined population, and the impact of these symptoms on presentation for medical care was measured. An age- and sex-stratified random sample of 1021 residents of Olmsted County, Minnesota, aged 30-64 years, was obtained. All subjects were mailed a valid self-report questionnaire that identified gastrointestinal symptoms and functional gastrointestinal disorders. The response rate was 82% (n = 835). The age- and sex-adjusted prevalence of abdominal pain (more than six times in the prior year) was 26.2 per 100 (95% confidence interval, 23.1-29.2). The prevalence of chronic constipation (hard stools and straining and/or less than 3 stools per week greater than 25% of the time) was 17.4 (95% confidence interval, 14.8-20.0), whereas the prevalence of chronic diarrhea (loose watery stools, and/or greater than 3 stools per day greater than 25% of the time) was 17.9 (95% confidence interval, 15.3-20.5). The prevalence of abdominal pain and disturbed defecation was similar in women and men, except that infrequent defecation and straining at stool were more common in women. Using the Manning symptom criteria to identify irritable bowel syndrome (greater than or equal to 2 of 6 symptoms in those with abdominal pain more than six times in the prior year), the prevalence of irritable bowel syndrome was 17.0 per 100 (95% confidence interval, 14.4-19.6). Overall, 71 persons (9%) reported visiting a physician for abdomi

OBJECTIVE: To evaluate the efficacy and cost-effectiveness of postoperative follow-up telephone calls among pediatric patients who underwent adenotonsillectomy. DESIGN: Prospective study with a follow-up questionnaire administered by telephone. SETTING: Tertiary-care children's hospital. PATIENTS: One hundred thirty-four children between the ages of 4 and 18 years who underwent adenotonsillectomy between December 1997 and June 1998 and did not have associated cardiac, pulmonary, bleeding, or syndromic disorders were included in this pilot study. INTERVENTION: Parents of these patients were given the opportunity to participate in our study, and it was emphasized that, at any time during the child's care, if the parent desired a follow-up visit or if the child experienced any symptoms that caused concern, the parent should contact the clinic for a follow-up appointment. A telephone call was placed 3 to 4 weeks postoperatively by an otolaryngology nurse, and a questionnaire was filled out using the parents' responses. MAIN OUTCOME MEASURES: The incidence rates of voice change, velopharyngeal insufficiency, bleeding, constipation, dehydration, and pain were measured. Parent satisfaction, patient safety, and cost-benefit were also evaluated. RESULTS: Less than 5% of patients reported temporary velopharyngeal insufficiency, while 2% of patients required operative intervention for bleeding episodes and 1% required hospitalization. Voice change, reported by approximately 70% of all patients, was the most common complaint, but it resolved in all instances. Pain was reported to be most severe on postoperative day 1. Ninety-six percent of parents requested no further follow-up visit. CONCLUSIONS: Our pilot study revealed that
