“…Unfortunately, the studies in this review were performed before the development of the Rome II criteria. Nevertheless, most estimates indicate that the prevalence of IBS is approximately 10 -15%, and this estimate is consistent with multiple non-US IBS studies summarized in previous review articles (20). An IBS prevalence of 10 -15% estimates that as many as 30 -45 million North American adults have symptoms of IBS during any given year.…”

OBJECTIVE:The aim of this study was to systematically review published literature about the prevalence, incidence, and natural history of irritable bowel syndrome (IBS) in North America. METHODS:A computer-assisted search of MEDLINE, EMBASE, and Current Contents/Science Edition databases was performed independently by two investigators. Study selection criteria included: 1) North American populationbased sample of adults; 2) objective diagnostic criteria for IBS (i.e., Rome or Manning criteria); and 3) publication in full manuscript form in English. Eligible articles were reviewed in a duplicate and independent manner. Data extracted were converted into individual tables and presented in descriptive form. RESULTS:The prevalence of IBS in North America ranges from 3% to 20%, with most prevalence estimates ranging from 10% to 15%. The prevalences of diarrhea-predominant and constipation-predominant IBS are both approximately 5%. Published prevalence estimates by gender range from 2:1 female predominance to a ratio of 1:1. Constipationpredominant IBS is more common in female individuals. The prevalence of IBS varies minimally with age. No true population-based incidence studies or natural history studies were found. In one cohort surveyed on two occasions 1 yr apart, 9% of subjects who were free of IBS at baseline reported IBS at follow-up producing an onset rate of 67 per 1000 person-years. In all, 38% of patients meeting criteria for IBS did not meet IBS criteria at 1-yr follow-up. CONCLUSION:Approximately 30 million people in North America meet the diagnostic criteria for IBS. However, data about the natural history of IBS is quite sparse and renewed efforts should be focused at developing appropriately designed trials of the epidemiology of IBS.

“…Considering that 1 in 3 people with complaints related to IBS seek medical help, we calculate that a minimum of half a million individuals consult a doctor for this problem in the Netherlands. [22][23][24][25] On the basis of these assumptions, some 20 thousand Dutch individuals with ACNES are currently misdiagnosed as having functional abdominal pain (95% CI, 9.500 -42.000). Using similar assumptions and calculations, some 400,000 US individuals with functional abdominal syndromes may suffer from an undiagnosed CAWP such as ACNES.…”

Introduction:The abdominal wall is often neglected as a cause of chronic abdominal pain. The aim of this study was to identify chronic abdominal wall pain syndromes, such as anterior cutaneous nerve entrapment syndrome (ACNES), in a patient population diagnosed with functional abdominal pain, including irritable bowel syndrome, using a validated 18-item questionnaire as an identification tool.Methods: In this cross-sectional analysis, 4 Dutch primary care practices employing physicians who were unaware of the existence of ACNES were selected. A total of 535 patients >18 years old who were registered with a functional abdominal pain diagnosis were approached when they were symptomatic to complete the questionnaire (maximum 18 points). Responders who scored at least the 10-point cutoff value (sensitivity, 0.94; specificity, 0.92) underwent a diagnostic evaluation to establish their final diagnosis. The main outcome was the presence and prevalence of ACNES in a group of symptomatic patients diagnosed with functional abdominal pain.Results: Of 535 patients, 304 (57%) responded; 167 subjects (31%) recently reporting symptoms completed the questionnaire. Of 23 patients who scored above the 10-point cutoff value, 18 were available for a diagnostic evaluation. In half of these subjects (n ‫؍‬ 9) functional abdominal pain (including IBS) was confirmed. However, the other 9 patients were suffering from abdominal wall pain syndrome, 6 of whom were diagnosed with ACNES (3.6% prevalence rate of symptomatic subjects; 95% confidence interval, 1.7-7.6), whereas the remaining 3 harbored a painful lipoma, an abdominal herniation, and a painful scar.

INTRODUCCIÓNLos trastornos funcionales gastrointestinales son muy frecuentes. De ellos un 70% de pacientes no buscan atención médica (1,2). A pesar de ello, uno de cada 4 pacientes que acude a las consultas médicas, y un 40% de los pacientes que acuden al médico especialista en gastroenterología, son diagnosticados de trastornos funcionales (3). La prevalencia en países industrializados es del 14 al 24% de mujeres y del 5 al 19% en hombres. La prevalencia es igual en blancos que negros. El gasto sanitario en exploraciones, consultas médicas y tratamientos es muy grande, más aún si se tiene en cuenta que un 50% de los pacientes toman medicación para sus sínto-mas (4).Los estudios de prevalencia de trastornos funcionales en países subdesarrollados son escasos, en algunos la prevalencia es similar a países industrializados (5,6) mientras que en otros es claramente inferior (7).
