[Most frequent causes of fecal incontinence in our environment].

The objective of this piece of work was to assess the most frequent causes of fecal incontinence in our environment. 204 patients undergoing fecal incontinence of various types of severity were evaluated and later referred to "motilidad digestiva" department of Gastroenterology floor of Hospital de Clínicas José de San Martín, in an eight year span of time, 58 male (28.43%) and 146 female (71.56%) of an average age of 56 years. Every patient underwent a serious anamnesis, a proctologic examination, anoscopy, a rectosigmoid study, an anorectal manometry, and, a preventive electromyography was performed to those patients with a possible neurologic damage. The most frequent cause of incontinence was idiopathic 37.7%, followed by post surgery (19.6%) and rectal prolapse (13.7%), post menopause (11.2%), post delivery (9.8%), Neurogenic Incontinence (4.9%) and Traumatic Incontinence (2.9%). Doctor's performance may prevent some of the causes of incontinence.

Antegrade continence enema for the treatment of neurogenic constipation and fecal incontinence after spinal cord injury.

OBJECTIVE: To describe the effects of an antegrade continence enema stoma formed in a paraplegic man with intractable constipation and fecal incontinence. DESIGN: Case report. SETTING: Spinal cord injury unit, Veterans Affairs hospital. PARTICIPANTS: Spinal cord injury (SCI) patient with T12 paraplegia. INTERVENTION: Surgical formation of antegrade continence enema stoma. MAIN OUTCOME MEASURES: Time of bowel program care, ease of fecal elimination, safety of procedure. RESULTS: Bowel care time was decreased from 2 hours to 50 minutes daily; 6 bowel medications were discontinued; fecal incontinence was eliminated; and no surgical or medical side effects noted after the procedure. CONCLUSION: The antegrade continence enema procedure is a safe and effective means of treating intractable constipation and fecal incontinence in the adult SCI patient. This option should be considered for those persons in whom medical management of bowel care has been unsuccessful.

Manometric asymmetry in the anal canal in controls and patients with fecal incontinence.

PURPOSE: This study was designed to ascertain the existence of manometric asymmetry in the anal canal in controls and in patients with fecal incontinence. METHODS: A computerized manometric technique with an eight-channel perfusion catheter was used. Coefficient of variation (CV, a mathematical expression of the degree or magnitude of deviation of a set of data points from the mean) was developed in this study as an index of anal canal manometric asymmetry. RESULTS: At 1 cm from the anal verge, mean CV was 9.3 and 8.7 percent in asymptomatic control males and females, respectively. During a maximum voluntary squeeze effort, mean CV in control males was 9.3 percent and was not significantly different (P = 0.28) from that in control females (7.8 percent). In 14 consecutive female patients with fecal incontinence, mean CV at rest (1 cm from the anal verge) was 21 percent and was significantly higher (P < 0.01) than in control females. Similarly, during a maximum voluntary squeeze effort, mean CV in patients with fecal incontinence was 20.5 percent and was significantly higher (P < 0.01) than in the female control group (7.8 percent). CONCLUSION: It is concluded that CV, a method of expressing anal sphincter manometric asymmetry, is a useful manometric parameter in the assessment of anorectal function.

Biofeedback treatment of fecal incontinence: a critical review.

PURPOSE: The aims of this review are 1) to critically evaluate the literature on the efficacy of biofeedback treatment for fecal incontinence, 2) to compare different types of biofeedback, and 3) to identify patient characteristics which predict a successful outcome. METHODS: The MEDLINE database was searched for articles published between 1973 and 1999 which included the terms "biofeedback" and "fecal incontinence." Pediatric and adult articles in any language were screened. Inclusion for review required that the study be prospective, have five or more subjects, and have a description of the treatment protocol. RESULTS: Thirty-five studies were reviewed. Only six studies used a parallel treatment design and just three of those randomized subjects to treatment groups. A meta-analysis (weighted by subjects) was performed to compare the results of two treatment protocols that dominate the literature. The mean success rate of studies using Coordination training (i.e., coordinating pelvic floor muscle contraction with the sensation of rectal filling) was 67 percent, while the mean success rate for studies using Strength training (i.e., pelvic floor muscle contraction) was 70 percent. Furthermore, the mean success rate for those Strength training studies using electromyographic biofeedback was 74 percent, while the mean success rate for studies using anal canal pressure biofeedback Strength training was 64 percent. However, these conclusions are limited by the absence of clearly identified criteria for determining success. There are also inconsistencies in the literature regarding the patient selection criteria, severity and cause of symptoms, amount of treatment, as well as the type of biofeedback protocols and instrumentation used. Finally, no patient characteristics were identified that would assist in predicting successful outcome. CONCLUSION: Although most studies report positive results using biofeedback to treat fecal incontinence, quality research is lacking. Recommendations are made for future investigations to 1) improve experimental design, 2) include long term follow-up data, and 3) to use an adequate sample size that allows for meaningful analysis.

Sacral nerve stimulation in fecal incontinence.

PURPOSE: The effect of sacral nerve stimulation was studied in 45 patients with fecal incontinence. METHODS: All patients were initially tested in general anesthesia. Sacral nerves 2, 3, and 4 were tested on both sides. If a perineal/perianal muscular response to sacral nerve stimulation could be obtained, electrodes were implanted for a three-week test-stimulation period. If sacral nerve stimulation resulted in at least a 50 percent reduction in incontinence episodes during the test period, a system for permanent sacral nerve stimulation was implanted. RESULTS: When tested in general anesthesia, 43 of 45 patients had a muscular response to sacral nerve stimulation and had electrodes implanted for the three-week test period. Percutaneous electrodes were used in 34 patients, and 23 of these had at least a 50 percent reduction in incontinence episodes, whereas the electrodes dislocated in 7 patients and 4 had a poor response. Permanent electrodes with percutaneous extension electrodes were used primarily in 9 patients and after dislocation of percutaneous electrodes in an additional 6 patients; 14 of these had a good result. In the last patient, no clinical response to stimulation with the permanent electrode could be obtained. A permanent stimulation system was implanted in 37 patients. After a median of six (range, 0-36) months follow-up, five patients had the system explanted: three because the clinical response faded out, and two because of infection. Incontinence score (Wexner, 0-20) for the 37 patients with a permanent system for sacral nerve stimulation was reduced from median 16 (range, 9-20) before sacral nerve stimulation to median 6 (range, 0-20) at latest follow-up ( P < 0.0001). There was no differences in effect of sacral nerve stimulation in patients with idiopathic incontinence (n = 19) compared with spinal etiology (n = 8) or obstetric cause of incontinence (n = 5). Sacral nerve stimulation did not influence anal pressures or rectal volume tolerability. CONCLUSIONS: Sacral nerve stimulation in fecal incontinence shows promising results. Patients with idiopathic, spinal etiology, or persisting incontinence after sphincter repair may benefit from this minimally invasive treatment.

Functional asymmetry of pelvic floor innervation and its role in the pathogenesis of fecal incontinence.

UNLABELLED: While the regular and symmetric innervation of the pelvic floor has been regarded as "established" for many years, recent data indicate that asymmetry of innervation of the sphincters may exists and may contribute to the occurrence and severity of incontinence symptoms in case of pelvic floor trauma. METHODS: A systematic review of published papers on asymmetry of sphincter innervation was performed including studies in healthy volunteers and patients with incontinence. 234 consecutive patients with fecal incontinence were investigated by means of side-separated mass surface EMG from the left and right side anal canal, these data were correlated to clinical and anamnestic findings. RESULTS: The literature survey indicates that asymmetry of sphincter innervation exists in a subgroup of healthy male and female volunteers, and may be a risk factor to become incontinent in case of trauma. Patients with incontinence in whom asymmetry of sphincter innervation could be shown more frequently reported a history of pelvic floor trauma during childbirth. Childbirth per se but not the number of deliveries predicted sphincter asymmetry. Asymmetrically innervated sphincters show a compromised sphincter function in routine anorectal manometry. CONCLUSION: Assessment of sphincter innervation asymmetry may be of value in clinical routine testing of patients with incontinence. However, a new technology is needed to replace mass surface EMG by multi-electrode arrays on a sphincter probe. This is one of the goals of the EU-sponsored research project OASIS.

Long-term results of lateral internal sphincterotomy for chronic anal fissure with particular reference to incidence of fecal incontinence.

PURPOSE: Lateral internal sphincterotomy is the procedure of choice for chronic anal fissure because it relieves symptoms and heals the fissure in nearly all patients. However, there is evidence that fecal incontinence complicates lateral internal sphincterotomy. The aim of this study was to examine the outcome of lateral internal sphincterotomy in terms of fissure healing and incidence of fecal incontinence. METHODS: Between 1984 and 1996, 585 patients underwent lateral internal sphincterotomy and were surveyed by questionnaire. Eighty-three percent (487/585) responded. The mean follow-up was 72 (range, 6-145) months. RESULTS: Fissures had healed by a median of three weeks after surgery in 96 percent of patients. Recurrent fissures occurred in 8 percent. Two thirds of the recurrent fissures healed on conservative management alone. Ninety-eight percent of patients were satisfied with the outcome of surgery, but some degree of fecal incontinence occurred in fully 45 percent of patients at some time in the postoperative period. Incontinence occurred in 53.4 percent of women and 33.3 percent of men (P < 0.05). Incontinence to flatus, mild soiling, and gross incontinence occurred in 31, 39, and 23 percent of patients, respectively. However, by the time of survey (a mean of >5 years after lateral internal sphincterotomy) 6 percent reported incontinence to flatus, 8 percent had minor fecal soiling, and 1 percent experienced loss of solid stool. Importantly, only 3 percent of patients stated that incontinence had ever affected their quality of life. CONCLUSION: Although lateral internal sphincterotomy heals and relieves symptoms of chronic anal fissure in nearly all patients (96 percent), incontinence occurs frequently. Most episodes of incontinence are indeed minor and transient, but in a small subgroup, incontinence seems to be permanent.

Surgical management of chronic unremitting constipation and fecal incontinence associated with megarectum: A preliminary report.

BACKGROUND/PURPOSE: Functional constipation with associated fecal incontinence responds poorly to medical management once megarectum has developed. The authors describe resecting the dilated rectum and inserting a cecostomy button for antegrade enemas in this difficult condition. METHODS: Four children, ages 9 to 15 years, with a history of unremitting constipation and fecal incontinence were referred for evaluation after not responding to medical management. All patients had exhibited normal lumbosacral magnetic resonance images (MRI) and open rectal biopsies; however, all 4 patients had a megarectum on contrast enema. In addition, anorectal manometry was consistent with functional fecal retention. The dilated rectum was resected by anastamosing the nondilated sigmoid colon to the distal rectum, and a standard gastrostomy button was inserted into the cecum for antegrade enemas. Mean follow-up was 35 months (range, 8 to 60 months). RESULTS: Constipation and incontinence resolved within 6 months in all patients, and all children remained continent without the aid of cathartic agents. There were no postoperative episodes of fecal impaction. The only complication was antibiotic-associated diarrhea in 1 patient. Cecostomy buttons were removed at 1 year postplacement in all 4 patients with continued success. Three patients underwent repeat anorectal manometry; all 3 had normal rectal sensory threshold volumes and anorectal inhibitory reflexes. Barium studies also were obtained in the 3 patients without evidence of recurrent rectal dilation. CONCLUSIONS: Refractory constipation and incontinence associated with megarectum may be amenable to surgical intervention in selected patients. The authors' limited experience suggests that proctectomy and button cecostomy is an effective treatment option that improves the quality of life in these patients. Furthermore, proctectomy alone may be curative.

Symptoms and quality of life in community women with fecal incontinence.

BACKGROUND & AIMS: Assessments of symptom severity are necessary to guide therapy in fecal incontinence (FI). However, there is no consensus on how self-reported symptom severity in FI should be measured for this purpose, and the relationship between symptoms of FI and its impact on quality of life (QOL) is not known. METHODS: A questionnaire was mailed to an age-stratified random sample of 5300 women identified through the Rochester Epidemiology Project. Symptom severity was assessed by a validated scale (Fecal Incontinence and Constipation Assessment [FICA]), and impact on 15 domains of QOL was evaluated for subjects who had any FI during the past year. The scale incorporated the type, frequency, and amount of FI, as well as the circumstances surrounding FI (ie, urge or passive FI). A QOL-weighted symptom severity score was derived by weighting the responses for these characteristics, in each subject, by the average QOL impact for all subjects who reported that specific symptom characteristic. The relationship between symptom severity and the QOL-weighted symptom severity score was assessed by Spearman rank correlation. RESULTS: Altogether, 2800 of 5300 (53%) women responded to the survey. FI symptoms were mild (45%), moderate (50%), or severe (5%). Among women with FI, the FICA symptom severity scale was strongly correlated (r(s) = 0.92, P < .0001) with the QOL-weighted symptom severity score. CONCLUSIONS: Among unselected women in the community, self-reported symptom severity, rated by the FICA scale, was strongly correlated with the impact of FI on QOL, supporting the use of this scale to assess symptom severity in FI.

Quality of life and morbidity after permanent sacral nerve stimulation for fecal incontinence.

HYPOTHESIS: Permanent sacral nerve stimulation (SNS) is a promising emerging treatment for fecal incontinence. However, there is little data on morbidity and quality of life (QOL) during long-term stimulation. DESIGN: Prospective trial to assess morbidity and QOL in patients treated with SNS. Median follow-up was 13 months (range, 1-42 months). SETTING: University hospital providing primary, secondary, and tertiary care. PATIENTS: Between December 2001 and July 2005, SNS was tested in 44 patients (30 women), with a median age of 65 years (range, 15-88 years). INTERVENTIONS: Percutaneous nerve evaluation and permanent insertion of an implantable pulse generator. MAIN OUTCOME MEASURES: Morbidity, stool diary, and Wexner Score for fecal incontinence; Hanley Score for urinary incontinence; and Gastrointestinal Quality of Life Index, the 36-item short form health survey, and the Royal London Hospital questionnaire for QOL. RESULTS: A permanent stimulator was implanted in 37 patients (84%). Eight patients (22%) experienced complications that required surgical intervention. (A successful restimulation was possible for 5 of those patients.) Adverse effects of SNS were remedied in 5 patients by reprogramming the stimulator. Wexner Scores decreased from a median of 16 points preoperatively (range, 6-20), to a median of 5 points postoperatively (range, 0-13; P<.001). The median number of involuntary stool losses and for urge defecations also decreased significantly. Significant improvement in QOL was found in both generic and incontinence-specific questionnaires (P<.05). The success rate of SNS was 77% (34 of 44 patients) and 92% (34 of 37) in patients with permanent implantation. CONCLUSIONS: The minimally invasive technique of SNS is safe and effective. Most adverse effects can be easily remedied. Our data demonstrate that SNS significantly improves patients' QOL, including their physical and psychological well-being.

Neuromodulation for fecal incontinence: outcome in 16 patients with definitive implant. The initial Italian Sacral Neurostimulation Group (GINS) experience.

PURPOSE: Sacral nerve modulation appears to offer a valid treatment option for some patients with fecal incontinence and functional defects of the internal anal sphincter or of the striated muscle. METHODS: Sixteen patients with fecal incontinence (4 males; mean age, 51.4 (range, 27-79) years) with intact or surgically repaired (n = 1) anal sphincter underwent permanent sacral nerve stimulation implant. Cause was traumatic in two patients, and associated disorders included scleroderma (2 patients) and spastic paraparesis (1 patient); eight (50 percent) of the patients also had urinary incontinence, and two (12.5 percent) had nonobstructive urinary retention. All patients were selected on the basis of positive findings from at least one peripheral nerve evaluation. The stimulating electrode was positioned in the S2 (1 patient), S3 (14 patients), or S4 (1 patient) sacral foramen. RESULTS: Mean follow-up was 15.5 (range, 3-45) months. Mean preimplant Williams score decreased from 4.1 +/- 0.9 (range, 2-5) to 1.25 +/- 0.5 (range, 1-2) (P = 0.01, Wilcoxon test), and the number of incontinence accidents for liquid or solid stool in 14 days decreased from 11.5 +/- 4.8 (range, 2-20) before implant to 0.6 +/- 0.9 (range, 0-2) at the last follow-up. Important manometric data were an increase in mean maximal pressure at rest of 37.7 +/- 14.9 mmHg (implantable pulse generator 49.1 +/- 18.7, P = 0.04) and in mean maximal pressure during squeeze (prestimulation 67.3 +/- 21.1 mmHg, implantable pulse generator 82.6 +/- 21.0, P = 0.09). CONCLUSIONS: Neuromodulation can be considered an option for fecal incontinence. However, an accurate clinical and instrumental evaluation and careful patient selection are required to optimize outcome.

Modified Thiersch procedure with silastic mesh implant: a simple solution for fecal incontinence and severe prolapse.

Most of the surgical procedures proposed for the treatment of fecal incontinence associated with prolapse are associated with considerable morbidity and mortality. We used a modified Thiersch procedure with a Silastic mesh implant (Dow-Corning 501-3) on a series of 12 patients over a period of 2 1/2 years. Nine patients obtained excellent control of the prolapse and incontinence. Only one patient was dissatisfied with her operation. The excellent results reported by other authors using a Silastic mesh implant have been reproduced in this small series of patients. This relatively safe and simple operation may still be the procedure of choice for fecal incontinence and rectal prolapse.

Rectal bleeding, fecal incontinence, and high stool frequency after conformal radiotherapy for prostate cancer: normal tissue complication probability modeling.

PURPOSE: To analyze whether inclusion of predisposing clinical features in the Lyman-Kutcher-Burman (LKB) normal tissue complication probability (NTCP) model improves the estimation of late gastrointestinal toxicity. METHODS AND MATERIALS: This study includes 468 prostate cancer patients participating in a randomized trial comparing 68 with 78 Gy. We fitted the probability of developing late toxicity within 3 years (rectal bleeding, high stool frequency, and fecal incontinence) with the original, and a modified LKB model, in which a clinical feature (e.g., history of abdominal surgery) was taken into account by fitting subset specific TD50s. The ratio of these TD50s is the dose-modifying factor for that clinical feature. Dose distributions of anorectal (bleeding and frequency) and anal wall (fecal incontinence) were used. RESULTS: The modified LKB model gave significantly better fits than the original LKB model. Patients with a history of abdominal surgery had a lower tolerance to radiation than did patients without previous surgery, with a dose-modifying factor of 1.1 for bleeding and of 2.5 for fecal incontinence. The dose-response curve for bleeding was approximately two times steeper than that for frequency and three times steeper than that for fecal incontinence. CONCLUSIONS: Inclusion of predisposing clinical features significantly improved the estimation of the NTCP. For patients with a history of abdominal surgery, more severe dose constraints should therefore be used during treatment plan optimization.

Treatment of constipation and fecal incontinence in stroke patients: randomized controlled trial.

BACKGROUND AND PURPOSE: Despite its high prevalence in stroke survivors, there is little clinical research on bowel dysfunction in this population. This is the first randomized controlled trial to evaluate treatment of constipation and fecal incontinence in stroke survivors. METHODS: Stroke patients with constipation or fecal incontinence were identified by screening questionnaire (122 community, 24 stroke rehabilitation inpatients) and randomized to intervention or routine care (73 per group). The intervention consisted of a 1-off structured nurse assessment (history and rectal examination), leading to targeted patient/carer education with booklet and provision of diagnostic summary and treatment recommendations (after consultation with geriatrician) to patient's general practitioner (GP)+/-ward physician. RESULTS: Percentage of bowel movements (BMs) per week graded as "normal" by participants in a prospective 1-week stool diary was significantly higher in intervention versus control patients at 6 months (72% versus 55%; P=0.027), as was mean number of BMs per week (5.2 versus 3.6; P=0.005). There was no significant reduction in fecal incontinence, although numbers were small. At 12 months, intervention patients were more likely to be modifying their diets (odds ratio [OR], 3.1 [1.2 to 8.0]) and fluid intake (OR, 4.2 [1.4 to 12.2]) to control their bowels and to have visited their GP for their bowel problem (OR, 5.0 [1.4 to 17.5]). GP prescribing of laxatives and suppositories was significantly influenced at 12 months. CONCLUSIONS: A single clinical/educational nurse intervention in stroke patients effectively improved symptoms of bowel dysfunction up to 6 months later, changed bowel-modifying lifestyle behaviors up to 12 months later, and influenced patient-GP interaction and physician prescribing patterns.

Correlating the Fecal Incontinence Quality-of-Life Score and the SF-36 to a proposed Ostomy Function Index in patients with a stoma.

Quality of life is affected by the creation of a stoma. To assess the validity of the Ostomy Function Index in patients with a stoma, a prospective survey was conducted from July 2000 to September 2001 among patients participating in local United Ostomy Association chapters (N = 99; 55 with a colostomy and 44 with an ileostomy). The Short Form 36 general health survey, Fecal Incontinence Quality of Life Scale, and the proposed Cleveland Clinic Florida Ostomy Function Index were used to assess general health and stoma function in patients with an ostomy. The average proposed function index score (7 = excellent function, 35 = poor function) was 11.97 (range 7 to 22). The proposed function Index correlated with the Fecal Incontinence Quality of Life Scale and the physical and mental component scales of the SF-36 (P < 0.05). The correlation between the proposed function index and the Fecal Incontinence Quality of Life Scale was stronger in colostomy than in ileostomy patients. With the exception of the SF-36 role-emotional domain in ileostomy patients, the function index correlated with all SF-36 scales (P <0.05) in both patient groups. The results of this study suggest that ostomy function is variable and correlates with quality of life and that the Fecal Incontinence Quality of Life Scale offers a limited assessment of quality of life in colostomy patients. The Cleveland Clinic Florida Ostomy Function Index offers an objective assessment of ostomy function that reflects on quality of life. Additional studies to refine measurement of quality of life in stoma patients are warranted.

Hyperbaric oxygen in the treatment of fecal incontinence secondary to pudendal neuropathy.

PURPOSE: Hyperbaric oxygen therapy has several physiologic effects on damaged nerves in animal models, which lead to an improvement in neurologic function. Idiopathic fecal incontinence secondary to pudendal neuropathy is usually treated with biofeedback, which shows improvement in only 50 percent of patients. METHODS: Thirteen patients (12 females, age range, 40-75 years) with chronic pudendal neuropathy and fecal incontinence were identified. They received 30 treatments of hyperbaric oxygen during a period of 6 weeks. Each treatment was at 2.4 atmospheres breathing pure oxygen for 90 minutes. Pudendal latencies were performed sequentially throughout the treatment and one and six months after it had finished. Questionnaires were used to assess improvements in symptoms and quality of life (Wexner fecal incontinence quality of life score). RESULTS: All patients completed the treatment without major complications. There was a consistent improvement of the latencies (on the left 2.36 msec initially, reduced to 2.08 msec at 6-month follow-up and on the right 2.23 msec, on the left reduced to 2.07 msec at 6 months). These improvements were significant (Wilcoxon's two-tailed, asymptomatic significance, comparing pretreatment to 6-month follow-up, left 0.005, right 0.003). Incontinence sores also improved (12.08 initially to 11.64 at the end of treatment, 10.55 at 1-month follow-up, and 10.45 at 6-month follow-up). Using the same test, the improvement in incontinence scores also was significant when comparing pre-end (0.05) and pre-one month (0.011) but not pre-six month (0.054). CONCLUSIONS: Hyperbaric oxygen therapy has improved pudendal nerve function and continence in this group of patients. The cause for this improvement in latencies is unclear at present but may be because of a direct effect on the nerve or an improvement in blood flow to the nerve through angiogenesis. However, these results are good enough to schedule further trials.

Anorectal functioning in fecal incontinence.

Manometric testing was performed on three groups of subjects: 14 patients complaining of fecal incontinence, 14 age- and sex-matched continent patients, and 14 sex-matched younger normal controls. The younger group displayed significantly stronger contractions of the external anal sphincter and puborectalis than the two patient groups, which did not differ. No differences were found in the relaxation of the internal and sphincter. The incontinent group required a significantly larger stimulus in order to detect rectal distension compared to either the continent patients or the younger normals. An additional group of unmatched normals and incontinent patients demonstrated significant differences in their ability to retain rectally infused saline. The patients leaked sooner and retained less; however, the performance of the normals was considerably reduced from that reported in previous studies. The aging process seems to result in weakening of the striated muscles of the anal canal, although fecal incontinence need not occur. The afferent limb of the anorectal sensorimotor mechanism does not necessarily deteriorate with aging. A lower threshold for sensation of rectal distension among continent individuals apparently helps them to avoid incontinent episodes, even though maximum contractile pressures in their anal canal are no different from a comparable group of incontinent individuals.

Cost-effectiveness of dynamic graciloplasty in patients with fecal incontinence.

PURPOSE: This study evaluates the cost-effectiveness of dynamic graciloplasty for intractable fecal incontinence. PATIENTS AND METHODS: The costs and effects of dynamic graciloplasty were measured in a prospective, longitudinal study and in a clinical trial. Forty-three patients with intractable fecal incontinence were evaluated before and after dynamic graciloplasty. Costs were obtained from the hospital information system and from patient-oriented questionnaires. We compared the costs of a dynamic graciloplasty with the costs of a colostomy. Colostomy costs were evaluated using a group of seven patients who had a stoma in place for incontinence for several years. Sensitivity analyses were included. RESULTS: Total direct costs of lifelong dynamic graciloplasty were $31,733 (United States dollars), costs of lifelong conventional treatment were $12,180 (United States), and costs of colostomy, including lifelong stoma care, were $71,576 (United States). The clinical success rate of dynamic graciloplasty was 74 percent. Quality of life after successful dynamic graciloplasty was better than with conventional treatment. CONCLUSION: We found that dynamic graciloplasty was more expensive than conventional treatment but resulted in a significantly higher quality of life. Stoma treatment was the least attractive alternative regarding both costs and effects. The Dutch Health Insurance Executive Board recommended reimbursement for the dynamic graciloplasty procedure.
