Incidence of opioid-induced esophageal dysfunction.

BACKGROUND: Retrospective studies have suggested that long-term use of opioids can cause esophageal motility dysfunction. A recent clinical entity known as opioid-induced esophageal dysfunction (OIED) has been postulated. There is no data from prospective studies assessing the incidence of opioid-induced effects on the esophagus. AIM: Evaluate the incidence of OIED during chronic opioid therapy. METHODS: From February 2017 to August 2018, all patients seen in the Pain Unit of the hospital, who started opioid treatment for chronic non-neoplastic pain and who did not present esophageal symptoms previously, were included. The presence of esophageal symptoms was assessed using the Eckardt score after 3 months and 1 year since the start of the study. In February 2021, the clinical records of all included patients were reviewed to assess whether esophageal symptoms were present and whether opioid therapy was continued. In patients presenting with esophageal symptoms, an endoscopy was performed and, if normal, a high-resolution esophageal manometry was performed. For a confidence level of 95%, a 4% margin of error and an estimated prevalence of 4%, a sample size of 92 patients was calculated. RESULTS: 100 patients were included and followed while taking opioids, for a median of 31 months with a range between 4 and 48 months. Three women presented with dysphagia during the first 3 months of treatment, being diagnosed with esophagogastric junction outflow obstruction; type II and type III achalasia. The cumulative incidence of OIED was 3%; 95%-CI: 0-6%. CONCLUSIONS: Chronic opioid therapy in patients with chronic non-neoplastic pain is associated with symptomatic esophageal dysfunction.

Decreased Esophageal Sensitivity to Acid in Morbidly Obese Patients: A Cause for Concern?

BACKGROUND/AIMS: To evaluate esophageal sensitivity to acid between morbidly obese (MO) patients and non-MO controls with abnormal esophageal acid exposure. METHODS: We conducted a cross-sectional study of 58 patients: 30 MO (cases) and 28 non-MO (controls). Esophageal symptoms and esophageal sensitivity to 0.1 M hydrochloric acid solution (Bernstein test) were compared between MO and non-MO patients with a prior diagnosis of abnormal esophageal acid exposure. RESULTS: MO patients were less symptomatic than non-MO controls (14% vs 96%; odds ratio [OR], 0.006; 95% confidence interval [CI], 0.001 to 0.075; p=0.000). MO patients were more likely to present with decreased esophageal sensitivity to the instillation of acid than non-MO controls (57% vs 14%; OR, 8; 95% CI, 1.79 to 35.74; p=0.009). Subgroup analysis revealed no differences in esophageal sensitivity in MO patients with and without abnormal esophageal acid exposure (43% vs 31%; p=0.707). CONCLUSIONS: Silent gastroesophageal reflux disease (GERD) is common among MO individuals, likely due to decreased esophageal sensitivity to acid. The absence of typical GERD symptoms in these patients may delay discovery of precancerous conditions, such as Barrett's esophagus. We believe that these patients may require a more aggressive diagnostic work-up to rule out the presence of silent GERD.

Effects of high-resolution esophageal manometry on oxygen saturation and hemodynamic function.

The effect of high-resolution esophageal manometry (HRM) on oxygen saturation (SaO2) and hemodynamic function has not been previously evaluated. This was a prospective study of consecutive patients referred for HRM. Demographic and clinical data were collected on all patients. The study variables included SaO2, heart rate (HR) and blood pressure (BP). SaO2 and HR were measured at baseline, during intubation, during and 5 min after HRM. BP was measured at baseline, during and after HRM. 158 (56% women) patients with a mean age of 56 (SD 15) years were included. Thirty-five (22%) were obese and 55 (35%) were overweight. Eighteen (12%) patients had a history of respiratory disease and 27 (17%) were smokers. Intubation was difficult in 22%. Exploration tolerance was poor in 17% or very poor in 6%. The average duration of the test was 9.9 (SD 2.8) minutes. Sixty-four (47%) and 59 (37%) patients had SaO2 below 95% during intubation and during HRM, respectively. Three patients had SaO2 ≤90%. Sixty-nine (44%) patients had tachycardia during intubation and 8 (5%) during HRM. The appearance of desaturation (SaO2 <95%) during intubation was associated with a lower basal SaO2; desaturation during HRM and 5 minutes after HRM was associated with a higher age, a higher BMI and a lower basal SaO2. HRM decreases SaO2 and increases heart rate primarily during the insertion of the probe, as part of the standard stress response and therefore HMR can be considered a safe procedure. However, in older and overweight patients, respiratory parameters should be monitored.

Prevalence of severe esophagitis in Spain. Results of the PRESS study (Prevalence and Risk factors for Esophagitis in Spain: A cross-sectional study).

BACKGROUND: *N.P. and M.P. contributed equally to this study.The current prevalence of esophagitis in southern Europe is unknown. In addition, the risk factors for reflux esophagitis are not fully understood. OBJECTIVE: The objective of this article is to assess the prevalence and risk factors for esophagitis in Spain. METHODS: A prospective, observational, cross-sectional, multicenter study (PRESS study) was conducted among 31 gastrointestinal endoscopy units throughout Spain. A total of 1361 patients undergoing upper gastrointestinal endoscopy were enrolled. Sociodemographic, clinical and treatment data were recorded. RESULTS: A total of 95% of patients were Caucasian and 52% were male (mean age: 53 ± 17 years). The most frequent symptoms prompting endoscopy were heartburn (40%), regurgitation (26%) and dysphagia (15%). Fifty-four percent of patients undergoing endoscopy were receiving proton pump inhibitor (PPI) treatment. Esophagitis (mainly mild-moderate) was present in 154 (12.4%) patients. The severe form was recorded in only 11 (0.8%) patients. Multivariate analysis results indicated that the likelihood of esophagitis was higher in men (OR = 1.91, 95% CI = 1.31-2.78), in patients with high GERD-Q scores (OR = 1.256, 95% CI = 1.176-1.343), weight increase (OR = 1.014, 95% CI = 1.003-1.025) and high alcohol consumption (OR = 2.49, 95% CI = 1.16-5.36). CONCLUSION: Severe esophagitis is a rare finding in the Spanish population. Male gender, high GERD-Q score, weight increase and high alcohol consumption are main risk factors for its appearance.

Chronic Cough.

Chronic cough (CC), or cough lasting more than 8 weeks, has attracted increased attention in recent years following advances that have changed opinions on the prevailing diagnostic and therapeutic triad in place since the 1970s. Suboptimal treatment results in two thirds of all cases, together with a new notion of CC as a peripheral and central hypersensitivity syndrome similar to chronic pain, have changed the approach to this common complaint in routine clinical practice. The peripheral receptors involved in CC are still a part of the diagnostic triad. However, both convergence of stimuli and central nervous system hypersensitivity are key factors in treatment success.

Small intestinal bacterial overgrowth in inactive Crohn's disease: influence of thiopurine and biological treatment.

AIM: To investigate the influence of thiopurines and biological drugs on the presence of small intestinal bacterial overgrowth (SIBO) in patients with inactive Crohn's disease (CD). METHODS: This was a prospective study in patients with CD in remission and without corticosteroid treatment, included consecutively from 2004 to 2010. SIBO was investigated using the hydrogen glucose breath test. RESULTS: One hundred and seven patients with CD in remission were included. Almost 58% of patients used maintenance immunosuppressant therapy and 19.6% used biological therapy. The prevalence of SIBO was 16.8%. No association was observed between SIBO and the use of thiopurine Immunosuppressant (12/62 patients), administration of biological drugs (2/21 patients), or with double treatment with an anti-tumor necrosis factor drugs plus thiopurine (1/13 patients). Half of the patients had symptoms that were suggestive of SIBO, though meteorism was the only symptom that was significantly associated with the presence of SIBO on univariate analysis (P < 0.05). Multivariate analysis revealed that the presence of meteorism and a fistulizing pattern were associated with the presence of SIBO (P < 0.05). CONCLUSION: Immunosuppressants and/or biological drugs do not induce SIBO in inactive CD. Fistulizing disease pattern and meteorism are associated with SIBO.

Instability of the faecal microbiota in diarrhoea-predominant irritable bowel syndrome.

The irritable bowel syndrome (IBS) is a functional gastrointestinal disorder with a largely unknown aetiology and a wide range of symptoms. Most cross-sectional studies carried out so far suggest subtle alterations in the structure of the intestinal microbiota that are barely reproduced, partly because of the high inter-subject variation in the community composition and disorder-specific features. We performed a longitudinal study to explore the within-subject variation in the faecal microbiota in two patients with IBS classified into the diarrhoea subtype and the healthy spouse of one of them. Faecal communities were monitored over 6-8 weeks and analysed through metagenomic and metatranscriptomic approaches. We found a higher temporal instability in the fraction of active microbiota related to the IBS condition and fluctuating symptoms. Strong and quick shifts in the distribution of the active microbiota and changes in the global pattern of gene expression were detected in association with acute diarrhoea, whereas microbial composition and encoded functions were more stable. The specific alterations in the microbiota were barely reproduced within and between patients. Further research is needed to assess whether these changes are a consequence of the abnormal gut function in acute diarrhoeic episodes and the potential usefulness of tackling them.

The appropriateness of colonoscopies at a teaching hospital: magnitude, associated factors, and comparison of EPAGE and EPAGE-II criteria.

BACKGROUND: The growing demand for colonoscopies and inappropriate colonoscopies have become a significant problem for health care. OBJECTIVES: To assess the appropriateness of colonoscopies and to analyze the association with some clinical and organizational factors. To compare the results of the European Panel of Appropriateness of Gastrointestinal Endoscopy (EPAGE) and the EPAGE-II criteria. DESIGN: Cross-sectional study. SETTING: Endoscopy unit of a teaching hospital in Spain. PATIENTS: Patients referred for colonoscopy, excluding urgent, therapeutic indications, and poor cleansing. MAIN OUTCOME MEASUREMENTS: Appropriateness of colonoscopies according to the EPAGE criteria. RESULTS: From 749 colonoscopies, 619 were included. Most patients were referred by gastroenterologists (66.1%) in an outpatient setting (80.6%). Hematochezia was the most frequent indication (31.5%) followed by colorectal cancer-related indications (27.3%); a clinically relevant diagnosis was established in 41%. Inappropriate use was higher with EPAGE (27.0%) than EPAGE-II (17.4%) criteria. Surveillance after colonic polypectomy and uncomplicated lower abdominal pain were the indications exhibiting higher inadequacy. Inappropriate use was less with older age, in hospitalized patients, with referrals from internal medicine, and in colonoscopies with clinically relevant diagnoses. Agreement between EPAGE and EPAGE-II was fair (weighted κ = 0.31) but improved to moderate (simple κ = 0.60) after grouping appropriate and uncertain levels. LIMITATIONS: The appropriateness criteria are based on panel opinions. Some patients (12%) could not be evaluated with the EPAGE criteria. CONCLUSIONS: Our study identifies substantial colonoscopy overuse, especially in tumor disease surveillance. The EPAGE-II criteria decrease the inappropriate rate and the possibility of overlooking potentially severe lesions.

Structural alterations of faecal and mucosa-associated bacterial communities in irritable bowel syndrome.

Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder in western countries. Previous studies on IBS, mostly based on faecal samples, suggest alterations in the intestinal microbiota. However, no consensus has been reached regarding the association between specific bacteria and IBS. We explore the alterations of intestinal bacterial communities in IBS using massive sequencing of amplified 16S rRNA genes. Mucosal biopsies of the ascending and descending colon and faeces from 16 IBS patients and 9 healthy controls were analysed. Strong inter-individual variation was observed in the composition of the bacterial communities in both patients and controls. These communities showed less diversity in IBS cases. There were larger differences in the microbiota composition between biopsies and faeces than between patients and controls. We found a few over-represented and under-represented taxa in IBS cases with respect to controls. The detected alterations varied by site, with no changes being consistent across sample types.

Prevalence of irritable bowel syndrome (IBS) in first-degree relatives of patients with inflammatory bowel disease (IBD).

BACKGROUND: Epidemiological studies have shown a greater prevalence of irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) among first-degree relatives of patients diagnosed of these diseases. However, it is not known whether relatives of patients with IBD have a greater prevalence of IBS than the general population. AIMS: To analyse the prevalence of IBS among first-degree relatives by consanguinity (parents, siblings and offspring) and affinity (spouses) of patients with IBD. MATERIALS AND METHODS: A prevalence study was conducted identifying 490 relatives of 91 patients with IBD. Of these, 404 met inclusion criteria; and 360 (response rate: 89.1%) answered the questionnaires. Subjects were invited to participate in the study through index cases (patients with IBD). The following variables were collected: age, sex, history of digestive diseases, kinship and cohabitation with the index case. The relatives completed a questionnaire to identify those who met Rome I and Rome II criteria for IBS. RESULTS: The overall prevalence of IBS among the first-degree relatives of patients with IBD was 49.4% and 10% according to Rome I and Rome II criteria respectively. IBS prevalence was higher in first-degree blood relatives than in spouses of patients (Rome I: 53.1% vs 29.1%, p=0.001; Rome II: 10.8% vs 5.4%, NS). No differences were found in IBS prevalence depending on whether relatives were living with the index case or not. CONCLUSION: IBS prevalence in first-degree relatives of patients with IBD is elevated. It is significantly greater in blood relatives, which suggests involvement of genetic and psychological factors rather than environmental factors.

Structured management strategy versus usual care for gastroesophageal reflux disease: rationale for pooled analysis of five European cluster-randomized trials.

BACKGROUND: Gastroesophageal reflux disease (GERD) has a major impact at the primary care level and there is a need to evaluate whether the diagnosis and therapeutic management of GERD in Europe needs to be improved. METHODS: This project was designed to test the hypothesis that a new primary care management strategy would improve outcomes for patients with GERD, compared with usual care, in Europe. The analysis pools five separate cluster-randomized studies conducted in Austria, Italy, Norway, Spain and Sweden. These studies used a strategy based on the self-administered GerdQ questionnaire to stratify adult patients with symptoms of heartburn or regurgitation according to the frequency and impact of symptoms. A score of ≥8 indicates a high probability of suffering GERD. Patients with a GerdQ impact score ≤2 were treated with generic proton-pump inhibitors according to local guidance, and patients with an impact score ≥3 were treated with esomeprazole 40 mg once daily. RESULTS: In total, 2400 patients were enrolled across the five studies. The protocols were modified by individual countries according to their local guidelines/requirements. In Norway, the new management strategy was compared with traditional routine endoscopy and 24-hour pH-metry, and encompassed proton-pump inhibitor reimbursement restrictions. Outcome measures differed by country, but included control of GERD symptoms, self-rated health status and work productivity, treatment changes, specialist referrals and physician adherence. GERD-related use of healthcare resources was also evaluated. CONCLUSION: The pooled analysis will determine whether a locally adapted primary care management strategy for GERD, using GerdQ as a patient-tailored diagnostic and therapeutic evaluation tool, is beneficial compared with usual care across five countries with different standard approaches to GERD management and control.

High prevalence of heartburn and low acid sensitivity in patients with idiopathic achalasia.

BACKGROUND: Heartburn is frequently reported by patients with achalasia before treatment. However, the esophageal sensitivity to acid as a possible mediator of this symptom has not been previously evaluated. AIM: To evaluate the prevalence of gastroesophageal reflux symptoms and the esophageal sensitivity to acid perfusion in patients with untreated achalasia. METHODS: Forty patients with achalasia were prospectively evaluated. Forty-three patients with gastroesophageal reflux disease comprised the control group (ten of them with Barrett's esophagus). Symptoms were evaluated by a structured clinical questionnaire. Objective assessment was performed by ambulatory 24-h esophageal pH monitoring and endoscopy. Esophageal sensitivity to acid was evaluated by esophageal perfusion of ClH 0.1 N. RESULTS: Fifteen (37%) of the 40 patients with achalasia presented heartburn, but only four of them had esophagitis and/or abnormal esophageal pH recording. Eight patients had abnormal pH recording. Three patients had esophagitis. The esophagus was sensitive to acid in seven (17%) patients with achalasia, three of them with heartburn and one with abnormal pH recording. In the control group, 40 of 43 (93%) presented heartburn. Acid perfusion was positive in 32 (74%). Sensitivity to acid was lower in patients with achalasia than in those with gastroesophageal reflux disease with or without Barrett's esophagus. CONCLUSIONS: The prevalence of heartburn in patients with achalasia is high, although its association with objective indicators of gastroesophageal reflux disease is weak. Patients with achalasia have lower esophageal sensitivity to acid than patients with GERD, suggesting that heartburn is does not arise from this condition.

The effects of thiopurine therapy on health-related quality of life in Inflammatory Bowel Disease patients.

BACKGROUND: The effect of thiopurine immunomodulators on health-related quality of life (HRQoL) in patients with inflammatory bowel disease (IBD) has been controversial. The aims were to evaluate the HRQoL in patients with IBD treated with thiopurines and assess the short- and long-term impacts of the treatment on HRQoL. METHODS: Ninety-two consecutive patients who started treatment with thiopurines were prospectively included. Evaluation of HRQoL was performed at months 0, 6, and 12 using two questionnaires, the Short-Form Health Survey (SF-36) and the Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS: Baseline score of IBDQ was 4,6, range (2,31-6,84), with an impairment of the five dimensions of HRQoL compared with inactive patients. Results obtained in 8 dimensions of SF-36 showed worse HRQoL than Spanish general population. At 6 months patients had a significant improvement in overall IBDQ score -5,8 (1,58 -6,97)- and also in all IBDQ dimensions. All the 8 dimensions of SF-36 obtained a significant improvement. At twelve months score of IBDQ was 6,1, range (2,7-6,98), with improvement in all dimensions compared with baseline and 6 months. SF-36 showed a similar significant improvement in all subscales. CONCLUSIONS: Thiopurine immunomodulators alone or with other treatments have a positive and long lasting impact on HRQoL of IBD patients.

[Lesser known aspects of gastroesophageal reflux disease: non-acid reflux and functional pyrosis]. / Aspectos menos conocidos de la enfermedad por reflujo gastroesofágico: pirosis funcional y reflujo no ácido.

Gastroesophageal reflux disease (GERD) is defined as a pathologic condition that develops when reflux of stomach contents produce annoying symptoms and/or complications. According to whether esophagitis is present, GERD is classified as being erosive and non-erosive. Functional pyrosis is defined by the presence of retrosternal burning for at least 6 months in the absence of structural or metabolic alterations, GERD, or motor disorders that could cause the symptoms. Currently, functional pyrosis does not include patients with an acid-sensitive esophagus or those who improve with antisecretory drugs, which differentiates this entity from non-erosive GERD. GERD has usually been identified with acid reflux. However, the availability of new diagnostic methods such as Bilitec and, especially, impedance monitoring has revealed that acid, weakly acidic and gas reflux is able to produce distressing symptoms and complications in some patients.

Constipation during pregnancy: a longitudinal survey based on self-reported symptoms and the Rome II criteria.

An increase in the prevalence of constipation during pregnancy has been suggested to occur. We designed a prospective study to evaluate the prevalence of constipation during pregnancy and puerperium, to investigate possible associations with eating habits and lifestyle, and to evaluate the frequency of laxative use. A structured questionnaire was developed addressing demographics, obstetric characteristics, lifestyle, eating habits, variables required for the diagnosis of constipation, and laxative use to evaluate the prevalence of constipation during pregnancy and puerperium. The questionnaire was administered in the obstetric clinic in the first trimester of pregnancy, and by telephone in the second and third trimesters, and in the puerperal period. The prevalence of self-reported constipation in these time periods was 45.4, 37.1, 39.4, and 41.8%, respectively. Prevalence defined by the Rome II criteria for the same time periods was 29.6, 19, 21.8, and 24.7%. These values were similar to the data previously reported for the female population. Agreement between the self-reported and Rome II results was moderate. The self-reported criterion showed high sensitivity in all time periods, using the Rome II criterion as gold-standard. No factor was associated with variations in the prevalence of constipation during pregnancy, though an increase was recorded in the consumption of fruit, vegetables, fiber, and water. The prevalence of constipation during pregnancy and puerperium is similar to that recorded among the female population from the same geographic area.

[Swallowing disorders: a challenge for the gastroenterologist]. / Trastornos de la deglución: un reto para el gastroenterólogo.

Alterations in the physiological mechanism of swallowing involve several anatomical structures performing complex and coordinated activities. These alterations can be secondary to various pathological conditions with highly varied causes. Consequently, the approach to patients with swallowing disorders represents a diagnostic challenge. The first difficulty arises in establishing a diagnosis of the syndrome, in which the presence of dysphagia is often the key symptom. The second difficulty lies in identifying the alteration: distinguishing between those affecting the oral and pharyngeal phases and those affecting the pharyngeal phase is clinically important since the etiology and diagnostic strategy will differ. Whenever possible, treatment should be etiological and should aim to restore the swallowing mechanism. Alternative routes for nutrition are sometimes required, either because etiological treatment is lacking or to avoid complications.

Impact of upper digestive symptoms in patients with irritable bowel syndrome.

BACKGROUND: Functional digestive disorders constitute a sizable proportion of gastroenterology and primary healthcare consultations, and have a negative impact on health-related quality of life. Dyspepsia and heartburn are often associated with irritable bowel syndrome (IBS); however, the incidence of these symptoms and their effect on IBS patients have not been evaluated. AIM: To investigate the clinical, psychological and health-related quality of life impact of upper digestive symptoms on IBS patients. METHODS: A prospective, observational, multicentered study was conducted in Spain: 517 IBS patients (Rome II criteria), grouped according to predominant symptoms of constipation (IBS-C), diarrhea (IBS-D) or alternating bowel habit (IBS-A) and 84 controls without IBS were recruited. Upper digestive symptoms were recorded in a 30-day diary. Health-related quality of life was evaluated by Irritable Bowel Syndrome Quality of Life and Euro-Quality of Life Five-Dimension Questionnaires; psychological well-being was evaluated by the Psychological General Well-Being Index. RESULTS: IBS patients had greater frequencies of upper digestive symptoms (72.3 vs. 6.0%), dyspepsia (21.1 vs. 4.8%) and heartburn (40.0 vs. 13.1%) (all P < 0.05) than controls. Prevalence of upper digestive symptoms was lower in patients with IBS-D than in those with IBS-C or IBS-A (P < 0.05). Health-related quality of life and psychological status were significantly worse in IBS patients with upper digestive symptoms than in those without. CONCLUSIONS: Upper digestive symptoms, frequently present in IBS patients, impair health-related quality of life and psychological status. This effect is greater in patients with IBS-C and IBS-A than in those with IBS-D. These data emphasize the importance of evaluating the presence of upper digestive symptoms in IBS patients.

Value of heartburn for diagnosing gastroesophageal reflux disease in severely obese patients.

OBJECTIVE: To evaluate the prevalence of gastroesophageal reflux disease (GERD) in severely obese patients and the association between symptoms and objective data of GERD in this population. RESEARCH METHODS AND PROCEDURES: A total of 158 consecutive severely obese patients (BMI > or = 40 kg/m(2)) were prospectively evaluated. Symptoms were evaluated by a structured clinical questionnaire. Objective assessment was made by ambulatory 24-hour esophageal pH monitoring and endoscopy. GERD was defined by the presence of symptoms or complications (esophagitis). The clinical criterion defining GERD was the presence of at least two episodes of heartburn per week. RESULTS: The mean age of the 138 patients subjected to complete study was 42.6 +/- 10.2 years, with a BMI of 50.1 +/- 6.9 kg/m(2) (range, 40.6 to 69.4 kg/m(2)); 78% were women. The prevalence of GERD evaluated by symptoms and/or esophagitis was 33.3% (46/138). Clinical criteria of GERD were present in 31/138 cases (22.5%), and 26 (18.8%) had esophagitis. In 69/138 patients (50%), pHmetry was abnormal. Fifty-three patients with esophagitis and/or abnormal pHmetry were asymptomatic. The sensitivity of heartburn as a diagnostic criterion of GERD in patients with severe obesity was 29.3%, with a specificity of 85.7%. No significant association was observed between severe obesity grade and the prevalence of symptoms and/or objective data. DISCUSSION: Asymptomatic gastroesophageal reflux (abnormal esophageal acid exposure and/or reflux esophagitis) is more common than symptomatic gastroesophageal reflux in severely obese patients. Increased BMI is not associated with a greater prevalence of GERD in these patients.

Adaptation to Spanish language and validation of the fecal incontinence quality of life scale.

PURPOSE: The aim of this study was to perform a psychometric evaluation of the Fecal Incontinence Quality of Life Scale in the Spanish language. METHODS: Eleven hospitals in Spain participated in the study, which included 118 patients with active fecal incontinence. All the patients filled out a questionnaire on the severity of their incontinence, a general questionnaire of health (Medical Outcomes Survey Short Form), and a Spanish translation of the Fecal Incontinence Quality of Life Scale (Cuestionario de Calidad de Vida de Incontinencia Anal), which consists of 29 items in four domains: lifestyle, behavior, depression, and embarrassment. On a second visit, patients repeated the Fecal Incontinence Quality of Life Scale. For each domain, an evaluation was made of temporal reliability, internal reliability, the convergent validity with the generic questionnaire of health, and the discriminant validity correlating the domains of Cuestionario de Calidad de Vida de Incontinencia Anal with the severity of fecal incontinence. RESULTS: For cultural adaptation, the answer alternatives for 14 items were modified. A total of 111 patients (94 percent) completed the study adequately. Temporal reliability (test-retest) was good for all domains except for embarrassment, which showed significant differences (P < 0.02). Internal reliability was good/excellent for all domains (Cronbach alpha >0.80, between 0.84 and 0.96). The four domains of Cuestionario de Calidad de Vida de Incontinencia Anal significantly correlated with the domains of the generic questionnaire on health (P < 0.01) and with the scale of severity of fecal incontinence (P < 0.001). All domains of Cuestionario de Calidad de Vida de Incontinencia Anal correlated negatively with the need to wear pads (P < 0.01) and with the presence of complete fecal incontinence. CONCLUSIONS: The Cuestionario de Calidad de Vida de Incontinencia Anal incorporates sufficient requirements of reliability and validity to be applied to patients with fecal incontinence.
