Patient and surgeon ranking of the severity of symptoms associated with fecal incontinence: the fecal incontinence severity index.
PURPOSE: The purpose of this research was to develop and evaluate a severity rating score for fecal incontinence, the Fecal Incontinence Severity Index. METHODS: The Fecal Incontinence Severity Index is based on a type x frequency matrix. The matrix includes four types of leakage commonly found in the fecal incontinent population: gas, mucus, and liquid and solid stool and five frequencies: one to three times per month, once per week, twice per week, once per day, and twice per day. The Fecal Incontinence Severity Index was developed using both colon and rectal surgeons and patient input for the specification of the weighting scores. RESULTS: Surgeons and patients had very similar weightings for each of the type x frequency combinations; significant differences occurred for only 3 of the 20 different weights. The Fecal Incontinence Severity Index score of a group of patients with fecal incontinence (N = 118) demonstrated significant correlations with three of the four scales found in a fecal incontinence quality-of-life scale. CONCLUSIONS: Evaluation of the Fecal Incontinence Severity Index indicates that the index is a tool that can be used to assess severity of fecal incontinence. Overall, patient and surgeon ratings of severity are similar, with minor differences associated with the accidental loss of solid stool.

The role of overlapping sphincteroplasty in traumatic fecal incontinence.
Fecal incontinence is one of the most distressing conditions. Even there is a great variety of etiologic factors, they can be systematized in two main categories; fecal incontinence with normal and fecal incontinence with abnormal function of pelvic floor muscles. The latter is more interesting for surgeons since this category includes the great majority of surgically caused and surgically correctable fecal incontinences. Disruption of the anal sphincter caused by obstetric injury, anorectal operations or external trauma is the commonest cause of fecal incontinence. In the period 1990-1999, 53 patients with fecal incontinence caused by sphincter injury were treated on the third department for colorectal surgery, First Surgical Clinic. There were 43 females and 10 males with a mean age of 36.1 years (range 18-64). Causes of fecal incontinence were: obstetric trauma 38 patients. (71%), fistulotomy 9 (17%), war injuries 3 (6%) and nonspecific 3 (6%). The severity of incontinence was graded by Browning--Parks's classification. There were no patients in group A and B, in group C were 11 patients and in D group 37 patients. Wexner score system was also utilized preoperatively and postoperatively to determine continence function more precisely. Clinical exam, anoscopy and special investigations, such as anal manometry, EMG and defecography were carried out in all cases. Period between injury and repair was between 6 months and 20 years. Severe pudendal neuropathy was present in 17 patients. Five patients had oostomies performed at the time of injury. In three cases was present traumatic cloaca and in one case rectovaginal fistula. Overlapping sphincter repair technique was carried out in all cases. Full bowel preparation and antibiotics were prescribed. Anterior sphincteroplasty was performed in 39 cases, lateral in 7, posterior in 3 and anterior sphincteroplasty + posterior plication of puborectalis (Parks operation) in 4 patients. Protective colostomy was not performed in any case. The outcome of the procedure was considered as excellent, good, fair and poor (excellent when full control of solid and liquid stool and flatus was achieved, good when there was continence to feces but not to flatus, fair when patients could control only solid feces and poor when only partial control of solid feces was obtained). The overall functional results were as follows: Excellent in 25 patients (47.2%), good in 12 (22.7%), fair in 11 (20.7%) and poor in 5 (9.4%). Wound infection occurred in 9 (16.9%) patients, leading to disruption of sutures in three patients with consequent poor results. Two of them were reoperated. The duration of follow-up was from 5 to 60 months. We conclude that an overlapping sphincteroplasty is a method of choice in treating fecal incontinence caused by trauma. The best results are achieved with anterior sphincteroplasty. Results of posterior sphincteroplasty were disappointing. If present, pudendal neuropathy directly influences the outcome of sphincteroplasty. Manometric studies correlate with the clinical outcome.

Diet strategies used by women to manage fecal incontinence.
Fecal incontinence occurs in community-living women who are elderly, as well as younger women, particularly after vaginal childbirth. Little is known about how women manage fecal incontinence in their everyday lives. Ten women who had fecal incontinence for at least 1 year participated in an audio-taped interview in a phenomenological study. Diet modification was identified as a key strategy for managing fecal incontinence. Various food types were avoided, restricted, or used as remedies. The meanings that the women applied to the diet strategies for managing fecal incontinence had 4 themes: restricting diet and eating patterns, eating and dealing with the consequences, treating fecal incontinence with foods and fluids, and lacking therapeutic guidance regarding diet modifications for fecal incontinence. The results of this study suggest that the continence nurse specialist recognize the important role and meaning of diet as a self-care strategy for women with fecal incontinence and address diet in their assessment and management recommendations.

Gluteus maximus augmentation for the treatment of fecal incontinence.
Fecal incontinence is a devastating problem for school-aged children and adults. Medical and biofeedback therapies are unsuccessful in most patients who have severely defective internal and external sphincters. Continued fecal incontinence frequently leads to social isolation and withdrawal. Gluteus maximus augmentation of the sphincter mechanism is one surgical method for treating fecal incontinence. The authors present their results with gluteus maximus augmentation of the anal sphincter and describe patient selection criteria. From 1992 through 1996, seven patients underwent gluteus maximus augmentation of the anal sphincter for fecal incontinence. Six of these patients were children 5 to 6 years of age who had major deficiencies of their anorectal sphincter demonstrated by manometry. One patient was a 56-year-old adult woman who had acquired idiopathic fecal incontinence. Four of the six children (67%) had imperforate anus and two had cloacal anomalies (33%). The augmentation was performed in three stages. A sigmoid-end colostomy with a Hartman's pouch was followed 1 month later by rotation of a portion of the gluteus maximus for anorectal sphincter augmentation. A colostomy take down was performed 2 to 4 months later. All patients underwent dilatation after sphincter augmentation and were taught muscle exercises for using their neosphincter during the period before colostomy take down. Four of six children and the adult are continent postoperatively (71%). Both patients who remain incontinent are unable to sense rectal distention clinically or on anal manometric analysis but have excellent voluntary sphincter tone. Fecal incontinence can be successfully treated with gluteus maximus augmentation in carefully selected patients. Patients unable to sense rectal distension are unlikely to benefit from this procedure. The presence of a rectal reservoir and a skin-lined anal canal also appear to be important in attaining fecal continence.

Respective value of pudendal nerve terminal motor latency and anal sphincter electromyography in neurogenic fecal incontinence.
Fecal incontinence may be related to a neurogenic injury. Electrodiagnostic tests including pudendal nerve terminal motor latency (PNTML) and external anal sphincter electromyography (AEMG) have been proposed to reveal anal nerve damage. The aim of this study was to assess the respective value of PNTML and AEMG in the diagnosis of fecal incontinence. This study included 80 women (range 23-85 years) with fecal incontinence secondary to obstetrical and/or surgical trauma. They were evaluated by performing PNTML and AEMG. The electrophysiological results were compared and interpreted in the light of anorectal manometry (ARM) results. Electrodiagnostic test abnormalities were found in 64 of 80 patients (80%), including 28 patients with abnormal results for both tests and 36 patients with only one abnormal test. Overall, a neurogenic AEMG pattern was found in 64% of patients and a prolonged PNTML in 51%. No correlation was found between PNTML value and either AEMG grade or ARM parameters, while AEMG grade strongly correlated with squeeze pressure measured by ARM. This study showed that AEMG and PNTML did not give redundant information and allowed to explicit the mechanisms of neurogenic fecal incontinence. We found that AEMG was more sensitive and more closely related to the anal functional status (ARM parameters) than PNTML. These electrodiagnostic tests, particularly AEMG as performed in everyday practice, are useful in the assessment of neurogenic fecal incontinence.

Assessing and treating patients with complex fecal incontinence.
Fecal incontinence is the involuntary loss of gas, liquid, and/or solid stool. It affects 2.2% of the general population. Because fecal incontinence can be socially and psychologically devastating, and is not easily discussed, this figure is probably understated. Patients presenting with fecal incontinence need to be properly assessed, including physiological testing of the pelvic floor muscles and nerves. Identifying any abnormal anatomy or physiology in the pelvic floor helps the clinician develop a care plan that best suits the patient's etiology. Knowledge of the physiology of the pelvic floor musculature and its effects on continence is improving. Treatment options also have broadened. This article describes the current techniques of assessment and treatment, including the "gold standard," and newer investigational procedures offered to patients with complex fecal incontinence.

Clinical, manometric, and EMG characteristics of patients with fecal incontinence.
Fecal incontinence occurs frequently in both men and women. Yet, few studies on fecal incontinence have separated the evaluation and interpretation of data by gender. This study was designed to identify differences in the clinical, anorectal manometry, and electromyography (EMG) characteristics between male and female patients with fecal incontinence. We compared 53 incontinent males (mean age, 64 years) with 72 incontinent females (mean age, 61 years). Each patient underwent computerized anorectal manometry, and invasive (pudendal nerve conduction studies and concentric needle EMG) and noninvasive EMG (anal sensor surface electrode). An anal incontinence score (AIS) ranging from 0 to 6 was used to categorize patients. Male patients had higher incontinence scores at presentation (AIS greater than 4, 70% vs. 54%). Female patients had significantly lower resting pressure (40 vs. 53 mmHg, p < 0.05) and more women had sphincter asymmetry (36% vs. 25%, p < 0.05). Both groups had similar PNTMLs (2.41 vs. 2.47 ms). Difference was seen in the net strength of the sphincter (women 4.0 microV vs. men 8.0 microV, p < 0.05), as measured by noninvasive EMG. In conclusion, it is well known that there are differences in anorectal physiologic function between male and female patients with normal continence. Comparing male and female patients with fecal incontinence suggests that female patients tend to have worse sphincter function that men. Both groups had similar EMG alterations, suggesting a common neurogenic injury as etiology. Future studies are needed to address the sexes separately.

Fecal incontinence.
Fecal incontinence is common and socially disabling. Only a few patients with fecal incontinence present to medical practitioners. Investigative techniques have improved, and it is possible now to define accurately functional or anatomic deficits. Careful planning of treatment with the possibility of using a variety of treatment modalities is essential. Novel conservative and surgical techniques have the potential to improve the outcome for patients with fecal incontinence.

A clinical approach to fecal incontinence.
Fecal incontinence is the impaired ability to control gas or stool. It is a disabling and distressing condition. Its exact incidence and prevalence are unknown. It is a disorder about which patients are frequently reluctant to discuss, even with their physician. However, it is a common condition especially in older individuals, where the prevalence has been reported to approach 60%. In women, incontinence reaches 54% as a result of childbirth. Of the patients surgically treated, the female-to-male ratio is 4 to 1. In an epidemiological study to identify its community-based prevalence, the University of Illinois determined fecal incontinence existed in 2.2% of the general population. There is available treatment for fecal incontinence. Many patients improve with conservative treatment (constipating agents, antidiarrheal medications, dietary changes) or with biofeedback. For patients where conservative treatment has failed, surgical treatment (direct-apposition sphincter repair, overlapping sphincteroplasty, postanal repair, neosphincter procedures) may be successful.

Manometric evaluation of defecation disorders: Part II. Fecal incontinence.
Fecal incontinence is a silent affliction that often leads to self-imposed ostracism. For many years, a lack of understanding regarding its pathophysiology and a lack of empathy among many physicians has bedeviled this problem. However, during the last two decades, remarkable strides have been made, both in the evaluation and in the treatment of incontinence. These advances stem from the ability to perform a detailed and comprehensive assessment of anorectal physiology. Anorectal manometry has spearheaded this renaissance. Manometry is not a single test but consists of a series of measurements that include an assessment of anal sphincter function, rectal sensation, rectoanal reflexes, and rectal compliance. Electrophysiological assessments such as pudendal nerve terminal latency can provide additional information regarding neuromuscular integrity. Newer techniques such as vectography, saline continence test, impedance planimetry, and prolonged ambulatory anorectal manometry have added a new dimension to the overall assessment. Radiological tests such as defecography and anal endosonography can provide complimentary information. These tests of anorectal function have advanced immensely our understanding of the pathophysiological mechanisms that are responsible for fecal incontinence. Equipped with sound objective information, today, it is possible to treat most incontinent patients with novel treatments that include medical, biofeedback, or surgical therapies. This is the second article in a two-part evaluation of defecation disorders that discusses the manometric evaluation of fecal incontinence.

Diagnostic testing in fecal incontinence.
Fecal incontinence is a common problem that disproportionately affects women and the elderly and has a significant impact on the quality of life. Incontinence is often multifactorial. Anorectal manometry, anal endosonography, magnetic resonance imaging, pudendal nerve latency, and electromyography provide morphologic and physiologic assessments of the internal and external anal sphincters, rectal motor and sensory function, rectal compliance, and rectoanal reflexes. This information, in concert, provides clues to the pathophysiology of fecal incontinence and may help to guide medical, surgical, or biofeedback therapy. These tests have also been used to assess the effectiveness of the therapeutic modalities. No data are available on the cost-effectiveness of diagnostic testing in fecal incontinence. Newer techniques, including electrophysiologic testing and morphologic imaging of the anorectum, are being pursued.

Pathophysiology of adult fecal incontinence.
Fecal incontinence occurs when the normal anatomy or physiology that maintains the structure and function of the anorectal unit is disrupted. Incontinence usually results from the interplay of multiple pathogenic mechanisms and is rarely attributable to a single factor. The internal anal sphincter (IAS) provides most of the resting anal pressure and is reinforced during voluntary squeeze by the external anal sphincter (EAS), the anal mucosal folds, and the anal endovascular cushions. Disruption or weakness of the EAS can cause urge-related or diarrhea-associated fecal incontinence. Damage to the endovascular cushions may produce a poor anal "seal" and an impaired anorectal sampling reflex. The ability of the rectum to perceive the presence of stool leads to the rectoanal contractile reflex response, an essential mechanism for maintaining continence. Pudendal neuropathy can diminish rectal sensation and lead to excessive accumulation of stool, causing fecal impaction, mega-rectum, and fecal overflow. The puborectalis muscle plays an integral role in maintaining the anorectal angle. Its nerve supply is independent of the sphincter, and its precise role in maintaining continence needs to be defined. Obstetric trauma, the most common cause of anal sphincter disruption, may involve the EAS, the IAS, and the pudendal nerves, singly or in combination. It remains unclear why most women who sustain obstetric injury in their 20s or 30s typically do not present with fecal incontinence until their 50s. There is a strong need for prospective, long-term studies of sphincter function in nulliparous and multiparous women.

Etiology and management of fecal incontinence.
Fecal incontinence is a challenging condition of diverse etiology and devastating psychosocial impact. Multiple mechanisms may be involved in its pathophysiology, such as altered stool consistency and delivery of contents to the rectum, abnormal rectal capacity or compliance, decreased anorectal sensation, and pelvic floor or anal sphincter dysfunction. A detailed clinical history and physical examination are essential. Anorectal manometry, pudendal nerve latency studies, and electromyography are part of the standard primary evaluation. The evaluation of idiopathic fecal incontinence may require tests such as cinedefecography, spinal latencies, and anal mucosal electrosensitivity. These tests permit both objective assessment and focused therapy. Appropriate treatment options include biofeedback and sphincteroplasty. Biofeedback has resulted in 90 percent reduction in episodes of incontinence in over 60 percent of patients. Overlapping anterior sphincteroplasty has been associated with good to excellent results in 70 to 90 percent of patients. The common denominator between the medical and surgical treatment groups is the necessity of pretreatment physiologic assessment. It is the results of these tests that permit optimal therapeutic assignment. For example, pudendal nerve terminal motor latencies (PNTML) are the most important predictor factor of functional outcome. However, even the most experienced examiner's digit cannot assess PNTML. In the absence of pudendal neuropathy, sphincteroplasty is an excellent option. If neuropathy exists, however, then postanal or total pelvic floor repair remain viable surgical options for the treatment of idiopathic fecal incontinence. In the absence of an adequate sphincter muscle, encirclement procedures using synthetic materials or muscle transfer techniques might be considered. Implantation of a stimulating electrode into the gracilis neosphincter and artificial sphincter implantation are other valid alternatives. The final therapeutic option is fecal diversion. This article reviews the current status of the etiology and incidence of incontinence as well as the evaluation and treatment of this disabling condition.

Geriatric fecal incontinence.
Fecal incontinence is a common problem in the elderly population,particularly in nursing homes, and is one of the common reasons for nursing home placement. In addition to the inconvenience of the incontinence for the patient and caregiver, it is associated with increased mortality. Identifiable physiologic changes in the anorectal region may contribute to the development of fecal incontinence.Fecal incontinence is a disorder of men and women, with an equal or greater prevalence in men in advancing years. All patients who have fecal incontinence warrant an initial medical evaluation,including the exclusion of fecal impaction. Cognitively impaired patients benefit most from habit training. Selected elderly patients who have fecal incontinence may benefit from biofeedback and surgical intervention.

Fecal incontinence.
Fecal incontinence is frequently seen in elderly patients, particularly in association with dementia. It can result from underlying disease, fecal stasis, or neurologic disorders, some of which are reversible. With proper care and treatment, it is possible to reduce the prevalence of fecal incontinence in elderly patients.

Dynamic graciloplasty for fecal incontinence.
Fecal incontinence is a socially incapacitating condition with associated high treatment costs. The most common cause of fecal incontinence is trauma during childbirth followed by surgical interventions. After unsuccessful conventional treatment, muscle transposition is the next treatment option. Two local muscles are used for this purpose: the gluteus and the gracilis muscles. With both muscles, long-term muscle contractions are difficult to maintain due to muscle fatigue. The gracilis muscle, however, is technically much easier to transfer and most activities of daily living and even sports are still possible. Experimental studies have shown that electrical stimulation of skeletal muscles can transform fatigue-prone muscles into fatigue-resistant muscles. In 1986, we started to perform graciloplasty procedures with intramuscular electrodes connected to an electrical stimulator. To date, 200 patients have been treated in our institution using dynamic graciloplasty. All patients had severe incontinence without control of liquid or solid feces, most of them had previously received unsuccessful treatment using other techniques. The mean age was 48 years, the average time that patients had been incontinent was 12.4 years, and the cause of incontinence were trauma (n = 99), congenital (n = 28), pudendopathy (n = 58), and low motor neurological lesions (n = 15). Of these patients, 76% were considered to have successful outcomes. Patients whose cause of incontinence was trauma or pudendopathy tended to respond better to this treatment than patients with anal atresia.

Imaging fecal incontinence.
Fecal incontinence is the inability to defer release of gas or stool from the anus and rectum by mechanisms of voluntary control. It is an important medical disorder affecting the quality of life of up to 20% of the population above 65 years. The most common contributing factors include previous vaginal deliveries, pelvic or perineal trauma, previous anorectal surgery, and rectal prolapse. Many physicians lack experience and knowledge related to pelvic floor incontinence disorders, but advancing technology has improved this knowledge. Increased experience with endoanal ultrasound and endoanal magnetic resonance imaging have given us a better understanding not only of the anatomy of the anal canal but also of the underlying morphological defects in fecal incontinence. Current imaging methods are emphasized and recent literature is reviewed.
