Prevalence and correlates of fecal incontinence in community-dwelling older adults.

OBJECTIVES: To determine prevalence and correlates of fecal incontinence in older community-dwelling adults. DESIGN: A cross-sectional, population-based survey. SETTING: Participants interviewed at home in three rural and two urban counties in Alabama from 1999 to 2001. PARTICIPANTS: The University of Alabama at Birmingham Study of Aging enlisted 1,000 participants from the state Medicare beneficiary lists. The sample was selected to include 25% black men, 25% white men, 25% black women, and 25% white women. MEASUREMENTS: The survey included sociodemographic information, medical conditions, health behaviors, life-space assessment (mobility), and self-reported health status. Fecal incontinence was defined as an affirmative response to the question "In the past year, have you had any loss of control of your bowels, even a small amount that stained the underwear?" Severity was classified as mild if reported less than once a month and moderate to severe if reported once a month or greater. RESULTS: The prevalence of fecal incontinence in the sample was 12.0% (12.4% in men, 11.6% in women; P=.33). Mean age+/-standard deviation was 75.3+/-6.7 and ranged from 65 to 106. In a forward stepwise logistic regression analysis, the following factors were significantly associated with the presence of fecal incontinence in women: chronic diarrhea (odds ratio (OR)=4.55, 95% confidence interval (CI)=2.03-10.20), urinary incontinence (OR=2.65, 95% CI=1.34-5.25), hysterectomy with ovary removal (OR=1.93, 95% CI=1.06-3.54), poor self-perceived health status (OR=1.88, 95% CI=1.01-3.50), and higher Charlson comorbidity score (OR=1.29, 95% CI=1.07-1.55). The following factors were significantly associated with fecal incontinence in men: chronic diarrhea (OR=6.08, 95% CI=2.29-16.16), swelling in the feet and legs (OR=3.49, 95% CI=1.80-6.76), transient ischemic attack/ministroke (OR=3.11, 95% CI=1.30-7.41), Geriatric Depression Scale score greater than 5 (OR=2.83, 95% CI=1.27-6.28), living alone (OR=2.38, 95% CI=1.23-4.62), prostate disease (OR=2.29, 95% CI=1.04-5.02), and poor self-perceived health (OR=2.18, 95% CI=1.13-4.20). The following were found to be associated with increased frequency of fecal incontinence in women: chronic diarrhea (OR=6.39, 95% CI=2.25-18.14), poor self-perceived health (OR=5.37, 95% CI=1.75-16.55), and urinary incontinence (OR=4.96, 95% CI=1.41-17.43). In men, chronic diarrhea (OR=5.38, 95% CI=1.77-16.30), poor self-perceived health (OR=3.91, 95% CI=1.39-11.02), lower extremity swelling (OR=2.86, 95% CI=1.20-6.81), and decreased assisted life-space mobility (OR=0.73, 95% CI=0.49-0.80) were associated with more frequent fecal incontinence. CONCLUSION: In community-dwelling older adults, fecal incontinence is a common condition associated with chronic diarrhea, multiple health problems, and poor self-perceived health. Fecal incontinence should be included in the review of systems for older patients.

Fecal incontinence related to pregnancy.

Fecal incontinence related to pregnancy is an underreported and debilitating physical problem that has psychosocial ramifications. Disruption of the external and internal anal sphincters, which may occur during vaginal delivery, is the most common etiologic factor. Endoanal ultrasound is a minimally invasive, simple, and accurate diagnostic tool used to confirm and guide management of sphincter complex disruption.

Fecal incontinence in elderly patients.

Fecal incontinence is a common and important problem in the care of the elderly. An understanding of the defecation mechanism, appropriate differential diagnosis, and the best choice of treatment method are necessary to control this problem. Establishing a regular bowel program takes time and energy, but when the final result is continence, it is time and energy well spent.

Comparison of the nutritional composition of diets of persons with fecal incontinence and that of age- and gender-matched controls.

PURPOSE: In our clinical and research experience, persons with fecal incontinence anecdotally report altered diet intake to avoid incontinence. The purpose of this study was to compare the dietary intake of 39 persons with fecal incontinence living in the community with that of age- and gender-matched control subjects who had normal bowel function. The diets of both groups were compared with recommended dietary allowances (RDAs) for their constituent nutrients. METHODS: Subjects prospectively recorded the type, amount, and method of preparing all foods and beverages ingested for 8 consecutive days. Diet records were analyzed using the Nutritionist IV software program. MAIN OUTCOME MEASURES: The main outcome measures were the amounts and percentage of the RDAs of macronutrients and micronutrients in the subjects' diets. RESULTS: There were no significant differences in the intake of total kilocalories, protein, fat, dietary fiber, caffeine, or lactose by the fecal incontinence and control groups. The fecal incontinence group had a greater intake of carbohydrates, manganese, and vitamin B(1) compared with the control group. Diets of both groups exceeded 100% of the RDA for protein, phosphorus, iron, sodium, potassium, Vitamins B(1), B(2), B(3), B(12), and C and folate. Diets of both groups had less than 50% of the RDA for biotin, chromium, copper, and manganese but did not differ significantly. The percentages of the RDA for calcium and vitamin D were 84% +/- 6% and 56% +/- 8% for the fecal incontinence group and 90 +/- 8 (P =.6) and 69 +/- 11 for the control group (P =.4). CONCLUSIONS: The diets of persons with fecal incontinence were similar to those of control subjects with normal bowel function. Both the fecal incontinence and control groups may improve their nutritional patterns by lowering sodium and protein intake and increasing dietary fiber and monounsaturated fat intake. Calcium and vitamin D supplementation may improve dietary deficiencies and lower disease risks. Including a nutritional assessment and consultation in the care of persons with fecal incontinence to improve their general health and prevent disease is recommended, but consideration must be given to altered diet patterns perceived by the patient to prevent fecal incontinence.

Sacral neuromodulation in treatment of fecal incontinence following anterior resection and chemoradiation for rectal cancer.

PURPOSE: Fecal incontinence may occur in patients who have undergone anterior resection for rectal cancer without presenting sphincter lesions. Chemoradiation may contribute to disrupting continence mechanisms. Treatment is controversial. Assessment of fecal incontinence in patients who agreed to integrate treatment for rectal cancer and treatment with sacral neuromodulation are reported. METHODS: Fecal incontinence following preoperative chemoradiation and anterior resection for rectal cancer was evaluated in four patients. A good response was observed during the percutaneous sacral nerve evaluation test, and so permanent implant of sacral neuromodulation system was performed. Reevaluation was performed at least two months after implant. RESULTS: After device implantation, the mean fecal incontinence scores decreased, and the mean number of incontinence episodes dropped from 12.0 to 2.5 per week (P < 0.05). Permanent implant resulted in a significant improvement in fecal continence in three patients, and incontinence was slightly reduced in the fourth. Manometric parameters agreed with clinical results: maximum and mean resting tone and the squeeze pressure were normal in three patients and reduced in one. In these same three patients, neorectal sensation parameters increased when the preoperative value was normal or below normal and decreased when the preoperative value was higher than normal, whereas in one patient in whom extremely low values were recorded all of the parameters decreased significantly. CONCLUSIONS: Fecal incontinence following anterior resection and neoadjuvant therapy should be carefully evaluated. If a suspected neurogenic pathogenesis is confirmed, sacral neuromodulation may be proposed. If the test results are positive, permanent implant is advisable. Failure of this approach does not exclude the use of other, more aggressive treatment.

Fecal incontinence and spinal cord abnormalities in seven dogs.

Seven dogs with fecal incontinence and abnormal gaits were evaluated. Fecal incontinence was characterized as defecation of normal stools without posturing. Duration of clinical signs prior to evaluation ranged from 5 months to 3 years. Five dogs had upper motor neuron (UMN) paraparesis, and 2 dogs had UMN tetraparesis. With magnetic resonance imaging, spinal cord abnormalities primarily involving the dorsal aspect of the spinal cord were identified in all dogs. Five dogs had focal abnormalities, and 2 dogs had diffuse abnormalities of the spinal cord. Of the dogs with focal spinal cord lesions, 4 had cystic spinal cord abnormalities and 1 had a meningioma. Surgery was performed on all dogs with focal lesions; 4 of the 5 dogs had resolution of fecal incontinence after surgery. Results in these dogs suggest that fecal incontinence can be associated with spinal cord abnormalities and, depending on the characteristics of the lesion, can resolve after surgical treatment of the abnormality.

Fecal incontinence in females older than aged 40 years: who is at risk?

PURPOSE: This study was designed to estimate the prevalence of, and identify risk factors associated with, fecal incontinence in racially diverse females older than aged 40 years. METHODS: The Reproductive Risks for Incontinence Study at Kaiser is a population-based study of 2,109 randomly selected middle-aged and older females (average age, 56 years). Fecal incontinence, determined by self-report, was categorized by frequency. Females reported the level of bother of fecal incontinence and their general quality of life. Potential risk factors were assessed by self-report, interview, physical examination, and record review. Multivariate logistic regression analysis was used to determine the independent association between selected risk factors and the primary outcome of any reported fecal incontinence in the past year. RESULTS: Fecal incontinence in the past year was reported by 24 percent of females (3.4 percent monthly, 1.9 percent weekly, and 0.2 percent daily). Greater frequency of fecal incontinence was associated with decreased quality of life (Medical Outcome Short Form-36 Mental Component Scale score, P = 0.01), and increased bother (P < 0.001) with 45 percent of females with fecal incontinence in the past year and 100 percent of females with daily fecal incontinence reporting moderate or great bother. In multivariate analysis, the prevalence of fecal incontinence in the past year increased significantly [odds ratio per 5 kg/m2 (95 percent confidence interval)] with obesity [1.2 (1.1-1.3)], chronic obstructive pulmonary disease [1.9 (1.3-2.9)], irritable bowel syndrome [2.4 (1.7-3.4)], urinary incontinence [2.1 (1.7-2.6)], and colectomy [1.9 (1.1-3.1)]. Latina females were less likely to report fecal incontinence than white females [0.6 (0.4-0.9)]. CONCLUSIONS: Fecal incontinence, a common problem for females, is associated with substantial adverse affects on quality of life. Several of the identified risk factors are preventable or modifiable, and may direct future research in fecal incontinence therapy.

Long-term efficacy of dynamic graciloplasty for fecal incontinence.

PURPOSE: Patients with end-stage fecal incontinence in whom all standard medical and surgical treatment has failed or is not expected to be effective can be treated by dynamic graciloplasty. The aim of this study was to review the long-term efficacy data. METHODS: Success was defined as a greater than 50 percent decrease in the frequency of incontinent episodes. Measured physiologic parameters included enema retention time and the difference in resting and squeezing pressures with and without stimulation. Measured quality-of-life parameters included the Medical Outcomes Study Short Form 36 Health Status Questionnaire, a Fecal Incontinence TyPE Specification, the Zung Self-Rating Depression Scale, the "state" portion of the State-Trait Anxiety Inventory, and the Visual Analog Scale, which were administered at baseline and through follow-up. Independent monitors collected data as part of a multicenter trial for patients who underwent dynamic graciloplasty from May 1993 to November 1999. RESULTS: There were 129 patients entered in the study, 115 of whom met eligibility criteria and were included in the efficacy outcome analysis. Twenty-seven patients entered the study with a preexisting functioning stoma; the remaining 88 patients did not have a functioning stoma at the time of enrollment. Success was achieved in 62 percent of nonstoma patients at 12 months; these results were sustained at 18-month and 24-month follow-up assessments (55 and 56 percent, respectively). The success rate in the stoma patients increased from 37.5 percent (9 of 24 patients) at 12 months to 62 percent (13 of 21 patients) at 18 months and was 43 percent at 24 months (9 of 21 patients), which reflects the increased number of patients whose stomas were closed. Although the measured physiologic continence parameters generally improved, these changes did not correlate with continence outcome. The group of patients (stoma and nonstoma) who underwent dynamic graciloplasty showed statistically significant improvements in quality of life as measured by Medical Outcomes Study Short Form 36 physical function (P = 0.006) and social functioning (P = 0.02) assessment. CONCLUSIONS: Dynamic graciloplasty was successful in the majority of patients with end-stage fecal incontinence. This result was usually achieved by 12 months after surgery in patients who did not have stomas and by 18 months in patients who had stomas at the time of dynamic graciloplasty surgery. These various improvements conferred by dynamic graciloplasty persisted during the two-year follow-up.

Fecal incontinence. Studies on physiology, pathophysiology and surgical treatment.

The thesis consists of ten previously published studies and a review. The physiological and pathophysiological mechanisms in fecal incontinence has been studied by anal manometry, both by standard static anal manometry and by a new method, dynamic anal manometry, where anal sphincter pressure can be measured during simultaneous opening and closing of the anal canal. Patients with fecal incontinence showed abnormal sphincter pressures more frequently when dynamic anal manometry was used compared to standard anal manometry. The physiology and pathophysiology of the rectum was studied using rectal compliance measurements. Patients with normal anorectal function had a large variation in rectal compliance. Patients with fecal incontinence had as a group, lower rectal compliance than continent patients. This may lead to increased frequency of incontinence episodes in patients with fecal incontinence. The relationship between idiopathic fecal incontinence and pudendal nerve terminal latency was studied in 178 patients. The far majority of patients had normal latencies, and there was no correlation between latency and anal manometry. In contrast to previous suggestions, idiopathic fecal incontinence does not seem to be caused by pudendal nerve damage. Reconstruction of the external anal sphincter in patients with fecal incontinence due to obstetric sphincter lesion showed a poorer functional result among patients older than forty years compared to younger. This indicates that the general muscular weakening with age contribute to the incontinence in these patients. The treatment of more complicated forms of fecal incontinence consists of, apart from conservative treatment or colostomi, mainly in muscle transpositions or artificial anal sphincter. Transposition of the distal part of the gluteus maximus muscle to encircle the anal canal, did not lead to acceptable continence in any of the patients studied. Transposition of the gracilis muscle lead to acceptable continence in half the patients. Patients where the transposed muscle were stimulated by a neurostimulator had satisfactory continence in most cases. However, with this method several re-operations were necessary in some patients. In addition, some patients developed severe evacuation difficulties. Implantation of an artificial sphincter resulted in long-term improvement of continence in that half of patients in whom the artificial sphincter remained implanted. The other half of the patients had the artificial sphincter explanted due to various reasons, most frequently due to infection around the device. In selected patients with more complicated fecal incontinence, stimulated gracilis transposition or implantation of an artificial anal sphincter may be offered as an alternative to colostomy. Sacral nerve stimulation is a new method which seems to provide the best results among the more advanced procedures. Its minimally invasive character also contribute to the increasing use of this method in the last few years. Evaluation and treatment of fecal incontinence is presently in a state of rapid change with focus on more elaborate investigative methods and more diversified treatment.

Functional changes after physiotherapy in fecal incontinence.

BACKGROUND: Physiotherapy is a common treatment option in patients with fecal incontinence. Although physiotherapy may result in relief of symptoms, to what extent improvement is associated with changes in anorectal function is still unclear. AIM: The aim of the present study was to investigate prospectively how anorectal function changes with physiotherapy and whether these changes are related to changes in fecal incontinence score. METHODS: Consenting consecutive patients (n=266) with fecal incontinence (91% women; mean age, 59 years) underwent anorectal manometry, anal and rectal mucosal sensitivity measurements, and rectal capacity measurement at baseline and after nine sessions of standardized pelvic floor physiotherapy. These findings were compared with changes in Vaizey incontinence score. RESULTS: On follow-up 3 months after physiotherapy, squeeze pressure (p=0.028), as well as urge sensation threshold (p=0.046) and maximum tolerable volume (p=0.018), had increased significantly. The extent of improvement was not related to age, duration of fecal incontinence, menopause, and endosonography findings. All other anorectal functions did not change. An improvement in the Vaizey score was moderately correlated with an increase in incremental squeeze pressure (r=0.14, p=0.04) and a decrease in anal mucosal sensitivity threshold (r=0.20, p=0.01). CONCLUSIONS: Physiotherapy improves squeeze pressure, urge sensation, and maximum tolerable volume. However, improved anorectal function does not always result in a decrease in fecal incontinence complaints.

Anorectal pressure gradient and rectal compliance in fecal incontinence.

To study whether anorectal pressure gradients discriminated better than standard anal manometry between patients with fecal incontinence and subjects with normal anal function, anorectal pressure gradients were measured during rectal compliance measurements in 36 patients with fecal incontinence and in 22 control subjects. Anal and rectal pressures were measured simultaneously during the rectal compliance measurements. With standard anal manometry, 75% of patients with fecal incontinence had maximal resting pressure within the normal range, and 39% had maximum squeeze pressure within the normal range. Anorectal pressure gradients did not discriminate better between fecal incontinence and normal anal function, since, depending on the parameters used, 61%-100% of the incontinent patients had anorectal pressure gradients within the normal range. Patients with fecal incontinence had lower rectal volumes than controls at constant defecation urge (median 138 ml and 181 ml, P < 0.05) and at maximal tolerable volume (median 185 ml and 217 ml, P < 0.05). We conclude that measurements of anorectal pressure gradients offer no advantage over standard anal manometry when comparing patients with fecal incontinence to controls. Patients with fecal incontinence have a lower rectal volume tolerability than control subjects with normal anal function.

Rectal compliance in the assessment of patients with fecal incontinence.

Rectal compliance (dV/dP) was studied in 31 patients with fecal incontinence, 8 patients with constipation, and 16 control subjects. Patients with fecal incontinence experienced a constant defecation urge at a lower rectal volume and also had a lower maximal tolerable volume and a lower rectal compliance than control subjects (median 126 vs. 155 ml, 170 vs. 220 ml, and 9 vs. 15 ml/mm Hg, respectively; P less than 0.05). Constipated patients had a higher constant defecation urge volume and maximal tolerable volume than controls (median, 266 ml and 300 ml; P less than 0.05). There was no differences in the parameters between patients with idiopathic fecal incontinence and patients with incontinence of traumatic origin, indicating that a poorly compliant rectum in patients with fecal incontinence may be secondary to anal incontinence due to the lack of normal reservoir function.

Idiopathic Constipation and Fecal Incontinence.

Patients with constipation or fecal incontinence have great potential for remediation. Both disorders warrant a thorough diagnostic evaluation to search for remediable causes, especially to identify defecation disorders. Constipation should be treated by relieving any impactions and then starting a course of fiber supplementation of at least 20 g per day. If not successful, other agents such as lactulose, polyethylene glycol solutions, or stimulants can be added. Biofeedback may be very helpful. If all else fails, several surgical procedures are available. Fecal incontinence should be treated by fiber supplements, encouragement of regularity, and enemas as needed. Kegel exercises and biofeedback are often helpful, but surgery may be needed and is most effective in recent onset or traumatically induced incontinence.

Combined anorectal manometry and defecography in 50 consecutive adults with fecal incontinence.

Fifty consecutive patients presenting with fecal incontinence were evaluated prospectively with anorectal manometry, defecography, and other tests of anorectal function to assess the clinical utility of defecography in fecal incontinence. Leakage of contrast at rest and failure to narrow the anorectal angle with pelvic squeezing were specific but not sensitive predictors of decreased sphincter pressures as determined by manometry. Thus, after manometry, defecography provided no additional information regarding sphincter strength. Retention of contrast in large rectoceles or incomplete rectal evacuation at defecography had excellent correlation with the presence of clinical symptoms of outlet obstruction constipation (present concurrently with incontinence) and indicated an etiology of outlet obstruction symptoms. Defecography may provide useful information in incontinent patients with outlet obstruction constipation symptoms but has little additive value to anorectal manometry in incontinent patients without such symptoms.

Physiologic variables that predict the outcome of treatment for fecal incontinence.

Identification of physiologic factors that predict response to fecal incontinence therapy would be helpful in choosing the optimal treatment and advising patients on the likelihood of a successful outcome. However, few physiologic parameters have been consistently identified as important in predicting response to either biofeedback or surgery. The process of isolating these factors has been hampered by heterogeneity in the definition of fecal incontinence, lack of consensus on what constitutes a successful outcome, lack of follow-up data, variations in the way "standard" treatments are implemented, and lack of properly powered randomized controlled trials. Among the physiologic variables that studies have generally found to be predictive of successful outcomes in biofeedback treatment are the threshold for external anal sphincter contraction after treatment, the inclusion of sensory training in treatment, and a reduction in volume for the first sensation after treatment. Factors that have not been found to be important in predicting outcome following biofeedback retraining include the duration of fecal incontinence, pudendal nerve damage, patient age, symptom severity, pretreatment anal canal pressures, and results of anal ultrasonography. The presence of some degree of anorectal sensation is the only preoperative assessment that has been found to be predictive of response to surgical therapy. It is recommended that outcome measures for fecal incontinence be more clearly defined, that future biofeedback studies elaborate the predictive value of pretreatment anorectal sensation and the response to sensory retraining, and that postsurgical measurements such as anal squeeze pressure and sphincter length be taken into account.

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.

New surgical options for fecal incontinence in patients with imperforate anus.

INTRODUCTION: Anorectal malformations are among the various etiologic factors causing fecal incontinence. Patients with imperforate anus are difficult to treat, specifically those with high lesions. The artificial bowel sphincter and electrically stimulated gracilis neosphincter are two relatively new techniques that have been used for the treatment of patients with severe refractory fecal incontinence. The aim of this study was to evaluate the results of these technologies in the treatment of patients with chronic fecal incontinence due to imperforate anus. METHODS: All patients with imperforate anus who had fecal incontinence and underwent either the artificial bowel sphincter procedure or the gracilis neosphincter procedure between February 1995 and December 2000 were evaluated. Preoperative and postoperative incontinence score (Cleveland Clinic Florida Incontinence Score; 0 = perfect continence; 20 = complete incontinence), quality of life, (Fecal Incontinence Quality of Life Scale, 29 items forming 4 scales), and manometric sphincter pressure results were compared. RESULTS: Eleven patients had artificial bowel sphincter and five had the gracilis neosphincter (one nonstimulated) procedure. There were 11 males and 5 females of a mean age of 25.3 (range, 15-45) years. The mean follow-up time was 1.7 years (5 months to 5.7 years). Eight (50 percent) complications occurred in six patients, including three with fecal impaction (all artificial bowel sphincter), three with device migration (two gracilis neosphincter, one artificial bowel sphincter), and two patients with concomitant wound infection (one gracilis neosphincter, one artificial bowel sphincter); no patients had the devices explanted. Fourteen patients had manometric data (10 artificial bowel sphincter and 4 gracilis neosphincter) available. The overall incontinence score decreased from a preoperative mean of 18.5 to a postoperative mean of 7.5 in the artificial bowel sphincter group (P < 0.01) and from 17.4 to 9.4 in the gracilis neosphincter group (P = 0.06). All four Fecal Incontinence Quality of Life scales increased in both the artificial bowel sphincter (lifestyle and depression/self-perception, P = 0.02; coping/behavior and embarrassment, P = 0.03) and the gracilis neosphincter (lifestyle and coping, P = 0.06; depression and embarrassment, P = 0.05) patients. As well, the mean resting and squeeze pressures increased with both techniques (artificial bowel sphincter: P = 0.008 and P = 0.02, respectively; gracilis neosphincter: P = 0.4 and P = 0.1, respectively). All results were statistically significant in the artificial bowel sphincter group. CONCLUSIONS: Artificial bowel sphincter and gracilis neosphincter are efficient methods to treat patients with imperforate anus. These techniques should be considered for patients with imperforate anus and severe fecal incontinence.

Fecoflowmetry in fecal incontinence.

The fecoflowmetric pattern of fecal incontinence was studied in 38 patients. 21 patients had complete and 17 partial incontinence. Twenty normal controls of matching sex and age were also studied. EMG of external anal sphincter and puborectalis as well as the measuring of anal pressure were done. The fecal flow rate was determined by means of the fecoflowmeter. In complete incontinence, the EMG of the rectal sphincters showed no activity, and the anal pressure was lower than controls at rest and on squeezing (p less than 0.0001). The fecoflowgram showed as 'minicurve' because the patients had leaked most of the enema before the test started. In partial incontinence the enema before the test started. In partial incontinence EMG of the sphincters showed subnormal activity on squeezing. The anal pressure recorded values lower than in the normal controls at rest (p less than 0.001) and on voluntary squeezing (p less than 0.0001), though they were higher than those of complete incontinence. The flow rate parameters and curve were characteristics. The evacuated volume as well as the mean and maximum flow rate were higher (p less than 0.001), while the flow time (p less than 0.001) and the time to maximum flow (p less than 0.01) were shorter than in normal subjects. The ascending limb of the flow curve rose more steeply and was smooth. There was no plateau. The descending limb sloped more gradually and showed fluctuations. Fecoflowmetry could thus be an investigative tool not only in diagnosing but also in identifying the type of fecal incontinence.
