Permanent sacral nerve stimulation for fecal incontinence.

OBJECTIVE: To characterize the longer-term therapeutic response of permanent sacral nerve stimulation for fecal incontinence and to delineate suitable indications and the mode of action. SUMMARY BACKGROUND DATA: A single report of permanent sacral nerve stimulation in three patients followed up for 6 months showed marked improvement in fecal continence. Acute evaluation has shown that the effect may be mediated by altered rectal and anal smooth muscle activity, and facilitation of external sphincter contraction. METHODS: Five women (age 41-68 years) with fecal incontinence for solid or liquid stool at least once per week were followed up for a median of 16 months after permanent implantation. All had passive incontinence, and three had urge incontinence. The cause was scleroderma in two, primary internal sphincter degeneration in one, diffuse weakness of both sphincters in one, and disruption of both sphincters in one. RESULTS: All patients had marked improvement. Urgency resolved in all three patients with this symptom. Passive soiling resolved completely in three and was reduced to minor episodes in two. Continence scores (scale 0-20) improved from a median of 16 before surgery to 2 after surgery. There were no early complications, and there have been no side effects. One patient required wound exploration at 6 months for local pain, and a lead replacement at 12 months for electrode displacement. The quality of life assessment improved in all patients. The resting pressure increased in four patients, but there was no consistent measured physiologic change that could account for the symptomatic improvement. CONCLUSIONS: In patients with sphincter degeneration and weakness, and possibly in those with sphincter disruption, sacral nerve stimulation markedly improves fecal incontinence.

Postanal repair for fecal incontinence--is it worthwhile?

PURPOSE: Patients with idiopathic or neurogenic incontinence without an isolated sphincter defect may be suitable candidates for a postanal repair. The aim of this study was to assess the results of postanal repair in patients with idiopathic or neurogenic fecal incontinence and to evaluate the role of various parameters, including preoperative physiologic testing on outcome. METHODS: Postanal repair was offered by a single surgeon to patients meeting the following criteria: incontinence score of at least 12 of 20, absence of an isolated anterior external anal sphincter defect, and failed conservative, medical, and biofeedback management. Physiologic investigation and clinical findings of female patients who had postanal repair for fecal incontinence between 1992 and 1998 were reviewed. Physiologic investigation included anorectal manometry, pudendal nerve terminal motor latency, concentric needle electromyography, and endoanal ultrasonography. Follow-up was obtained by telephone questionnaire; moreover, patients were asked to grade the outcome of their surgery as excellent or good (success) or as fair or poor (failure). RESULTS: Twenty-one patients of median age 68 (range, 40-80) years had a mean duration of fecal incontinence before postanal repair of 6.8 (range, 0.5-22) years. Twenty patients (95 percent) were available for at least one year of follow-up. Seventeen patients (80.9 percent) had at least one prior vaginal delivery, and prior sphincteroplasty had been performed in 10 patients (47.6 percent). The morbidity and mortality rates were 5 and 0 percent, respectively. After a mean follow-up period of three (range, 1-7.5) years, seven patients (35 percent) considered surgery to be successful and had a statistically significant decrease in their incontinence score. Neither prolongation of pudendal nerve terminal motor latency nor external sphincter damage as noted on electromyography or any of the preoperative manometric parameters correlated with outcome. Furthermore, patients' ages at surgery did not correlate with the degree of postoperative improvement in continence scores nor did the duration of the patients' symptoms, number of vaginal deliveries, or a history of previous surgery for fecal incontinence. CONCLUSION: None of the factors assessed was demonstrated to be predictive of outcome after postanal repair; moreover, the currently available preoperative testing has not altered the success rate, which remains low (35 percent). Despite the low success rate, the absence of any mortality and the low morbidity suggest that postanal repair may be a valid therapeutic approach. However, it should be offered only to selected patients with persistent, severe fecal incontinence despite an anatomically intact external anal sphincter who are not candidates for or refuse all other operative modalities.

Left-colon antegrade continence enema (LACE) procedure for fecal incontinence.

PURPOSE: Antegrade continence enemas (ACE) are an efficacious therapeutic option for patients with fecal incontinence. The authors review their institution's experience with a variation of the Monti-Malone ACE procedure using the left colon as a source of an intestinal conduit and enema reservoir. METHODS: From 2000 to 2002, 18 patients with fecal incontinence or intractable constipation underwent left-colon ACE (LACE) procedure. Concomitant Mitrofanoff appendicovesicostomy was performed in 15 patients and bladder augmentation in 9. The majority of patients had neural tube defects. A segment of left colon was tubularized, tunneled into the muscular wall of the distal colon, and exteriorized through the left upper quadrant or midabdomen. Stomal catherization and enema installation were started one month postoperatively. RESULTS: Fifteen patients (83%) achieved fecal continence, 2 remain incontinent of stool, and 1 experienced stomal closure (mean follow-up was 24 +/- 9 months). Two patients had stomal stenosis that required revision. The mean enema volume in patient's achieving continence was 360 +/- 216 mL, and the mean transit time was 18 +/- 12 minutes. CONCLUSIONS: LACE is an efficacious procedure for fecal incontinence that can be performed safely at the time of major urologic reconstruction. Administration of enemas into the left colon has several physiologic advantages that result in predictable bowel evacuation.

Constipation and fecal incontinence in the elderly.

The successful management of constipation and fecal incontinence in the elderly requires an understanding of colorectal function, careful delineation of the patient's complaint, and in selected patients, specialized studies of colonic and anorectal function. This article reviews (1) the prevalence and nature of lower bowel dysfunction in the elderly population: (2) colonic and anorectal physiologic changes that are associated with aging; (3) the causes, consequences, and approaches to the management of constipation in the elderly; and (4) the causes of fecal incontinence in this age group and the treatment available.

A 10-year follow-up of urinary and fecal incontinence among the oldest old in the community: the Canadian Study of Health and Aging.

Urinary incontinence is common in the elderly. The epidemiology of fecal and double (urinary and fecal) incontinence is less known. The Canadian Study of Health and Aging (CSHA) is a national study of elderly living in the community at baseline (n = 8,949) and interviewed in 1991-1992, 1996, and 2001. Using data from the CSHA, we report the prevalence of urinary, fecal, and double incontinence in each wave and the cumulative incidence between waves and investigate the predictors of urinary and fecal incontinence. Urinary incontinence increased rapidly in old age, being almost twice as high in women as in men. Fecal and double incontinence were less common, but also increased rapidly with age. In women, parity showed a positive relationship with (prevalent) urinary incontinence. In men, diabetes was a risk factor for urinary and fecal incontinence. We conclude that urinary, fecal, and double incontinence increase rapidly with age and that inquiry about incontinence should be part of routine medical and nursing assessment of all elderly.

Ischemic fecal incontinence and rectal angina.

In 36 patients who consulted for fecal incontinence or rectal pain, or both, there was grossly visible scarring of the rectum and biopsy revealed mucosal atrophy and fibrosis. A steal from the hemorrhoidal arteries to the iliac vessels was demonstrated in 3 subjects. Maximum tolerable volumes within a rectal balloon were smaller than in control subjects, both in men (192 vs. 273 ml) and in women (142 vs. 217 ml) (p less than 0.01). The rectoanal inhibitory reflex was abnormal in all but 1 patient. Specific abnormalities were a decreased amplitude or a prolonged duration of the reflex. It was totally absent in 2 patients. This study is compatible with the hypothesis that chronic ischemia of the rectum may cause fecal incontinence or rectal pain.

Endosonography for assessment of anorectal changes in patients with fecal incontinence.

Our aim was to evaluate the anorectal changes in patients with fecal incontinence by using different endoultrasound techniques. Eighteen females with fecal incontinence and 14 healthy controls (females) were examined. Rigid linear transducer and 10 MHz radial scanning miniprobe were used. Statistically significant difference was found in the mean percentage of decreasing of the anorectal angle during contraction between healthy subjects (21.4%) and incontinent patients (7.5%). The mean percentage of shortening of the puborectal muscle length during squeezing was significantly lower in patients (9.6%) than in controls (17.9%). By means of miniprobe the anal sphincter defects were clearly demonstrated. Endosonography with a radial scanning miniprobe and rigid linear transducer ensures complex morphological and functional assessment of the anorectal region.

[German Artificial Sphincter System--GASS. Development and in vitro evaluation of a novel, fully-implantable, highly integrated sphincter prosthesis for therapy of high-grade fecal incontinence].

No highly integrated sphincter prosthesis for therapy of major fecal incontinence exists. Therefore, we developed a novel neosphincter, made of polyurethane. The GASS consists of a support ring (SR) which includes a fluid reservoir, fixed on the outer diameter of the SR, and a multi-chamber occluding cuff (C(int)) on the inside diameter. The total inflation volume of C(int) is about 23 cc. The integrated micropump based on piezotechnology measures 30x13x1 mm3 (flowrate 1.4 cc/min, max. backpressure 40,000 Pa) . GASS was evaluated around the external sphincter of isolated porcine anal canals. The threshold of continence was defined as the inflating volume which water ceased to leak through the area occluded by C(int) under an induced rectal pressure of 150 cm H2O. Minimal filling volumes maintained continence for liquids against high luminal pressures. A low intraanal resting pressure (delta p(anal)) induced by activated GASS indicates a little risk of ischemic injury of the anal canal in vivo (median delta p(anal) 24.1 mm hg:15 cc vs 46.9 mm hg:21 cc). In summary, a highly integrated and efficient high-tech neosphincter for the therapy of major fecal incontinence could be realized.

[Integrated study of fecal incontinence with defecography, anal ultrasonography, perineography, and manometry].

INTRODUCTION: Imaging methods such as defecography, anal US and perineography, combined with manometry, now permit to identify a growing number of causes of anorectal and pelvic floor deficiency. Fecal incontinence patients can thus be approached correctly relative to both diagnosis and treatment. We investigated the role of these techniques in the work-up of fecal incontinence. MATERIAL AND METHODS: Thirty-eight subjects suffering from fecal incontinence were examined. Defecography was carried out with a special commode and videorecorded on a VHS cassette. Anal US was performed with a 7-MHz rotating probe (type 1846) with 3-cm focus length. Perineography was carried out in 15 female patients. RESULTS: The anorectal angle (ARA) at rest was increased (mean: 106 degrees; normal range: 90-100 degrees) in 34 cases; involuntary barium leakage was seen in 8 patients, especially on coughing. On squeezing, ARA was normal in 10 cases (mean: 72 degrees; normal range: 60-90 degrees); in 5 cases of puborectal hypotonia there was no angular excursion between rest and squeezing (mean: 105 degrees). During evacuation, the average ARA value was 166 degrees in 21 cases and ARA stretched to verticalization in 8 cases (mean: 179 degrees). Morphofunctional anorectal changes appeared as rectal mucosal prolapse (12 cases), rectocele (10 cases), perineal descent syndrome (8 cases) and external rectal prolapse (3 cases). Anal US identified 15 interruptions in sphincterial rings: 12 patterns were hypoechoic, 2 mixed and 1 hyperechoic. Atrophic thinning of internal anal sphincter was seen in 5 idiopathic incontinence patients. Perineography demonstrated cystocele in 5 cases and cystourethrocele in 1 case. Manometry showed sphincterial hypotonia at rest in 15 cases, lower values of anorectal pressure on squeezing in 8 and smaller air volumes inhibiting external sphincterial tone in 19 cases. CONCLUSIONS: Defecographic studies with evaluation of ARA and its changes are an important tool with high diagnostic yield. When combined with other techniques, they provide differential criteria for sphincterial and puborectal causes and permits to identify associated pelvic floor dysfunctions. We believe that defecography, anal US (and perineography in complex disorders) are necessary techniques for the correct clinical approach to fecal incontinence patients, whose role and diagnostic yield are a valid support to manometry.

Prospective comparison of short- and long-term effects of pelvic floor exercise/biofeedback training in patients with fecal incontinence after surgery plus irradiation versus surgery alone for colorectal cancer: clinical, functional and endoscopic/endosonographic findings.

OBJECTIVE: The influence of irradiation on the clinical severity of incontinence, sphincter function, morphologic features and short/long-term treatment effects of sphincter training therapy is still insufficiently understood in irradiated patients with fecal incontinence after surgery for colorectal cancer. These parameters were compared in irradiated and non-irradiated patients and followed prospectively with regard to short- and long-term training effects. MATERIAL AND METHODS: Forty-one patients having been irradiated after surgery (50.0+/-5.0 Gy) and 54 non-irradiated patients with fecal incontinence participated in this prospective, non-randomized trial. Baseline evaluation included a semiquantitative severity assessment score of fecal incontinence (modified Cleveland Incontinence Score (MCIS)), rectal manometry and endoscopy. After 3 weeks (short term) of intensive in-hospital pelvic floor exercise combined with biofeedback training, a second evaluation was made. In addition, anal endosonography (EUS) was performed in cases of treatment failure. After one year (long term) a third evaluation was made clinically (MCIS score). RESULTS: Irradiated patients presented with a significantly higher degree of fecal incontinence (lower MCIS) compared to non-irradiated patients: 7.4+/-2.2 versus 8.7+/-2.7 points (p<0.001). Rectosigmoidal inflammation was more frequent in irradiated than non-irradiated patients (26.9% versus 9.3%) (p<0.03). Sphincter pressure, sensation/pain threshold and the rectoanal inhibitory reflex were similar in both groups. A significant short-term training effect was observed in both groups following sphincter training therapy in terms of an increase in MCIS from 7.4+/-2.2 to 9.4+/-2.7 points in the irradiated group and from 8.7+/-2.7 to 11.4+/-2.5 points in the non-irradiated group (p<0.0001). After one year the scores were 8.2+/-3.8 and 10.7+/-4.4 points, respectively (p<0.0001). There was a significant correlation (p<0.001) between baseline MCIS and the short- and long-term MCIS. In patients with short-term treatment failure (16.6%) anal EUS revealed structural defects of the external sphincter in four patients. There was no association of sphincter diameter with sphincter pressure, sensation/pain threshold and short/long-term MCIS. CONCLUSIONS: The main result of this study is that irradiated patients show short- and long-term training effects comparable with those of non-irradiated patients despite the higher degree of incontinence at baseline. The correlation between the initial MCIS and short- and long-term treatment effects may be regarded as an important clinical predictor for treatment outcome. Functional and morphologic features are less suitable for this purpose.

A prospective evaluation of the value of anorectal physiology in the management of fecal incontinence.

PURPOSE: This study was designed to determine whether anorectal physiology testing significantly altered patient management in the setting of fecal incontinence. METHODS: Patients referred to the anorectal physiology laboratory for evaluation of fecal incontinence were prospectively interviewed and examined by a colon and rectal surgeon. A decision to treat either medically or surgically was reached. The patients underwent physiologic testing with transanal ultrasound, pudendal nerve terminal motor latency, and anorectal manometry. A panel of board-certified colon and rectal surgeons then reviewed the history and physical examination, as well as the anorectal physiology tests, of each patient and reached a consensus on management. Management plans before and after physiologic evaluation were compared. RESULTS: Ninety patients (6 males) were entered into the study. The patients were divided in two groups: those with pretest medical management plans (n = 45) and those with pretest surgical management plans (n = 45). A change in management was noted in nine patients (10 percent). In the medical management group, the management changed from medical to surgical therapy in five patients. Transanal ultrasound detected anal sphincter defects in all patients who changed from medical to surgical management but in only 10 percent of those who remained under medical management (P = 0.0001). In the surgical management group, three patients (7 percent) changed from surgical to medical therapy and one patient (2 percent) changed from sphincteroplasty to neosphincter. Transanal ultrasound detected a limited anal sphincter defect in one patient (33 percent) who changed from surgical to medical management and a significant defect in all 41 patients (100 percent) who remained under surgical management (P = 0.003). CONCLUSIONS: Anorectal physiology testing is useful in the evaluation of patients with fecal incontinence. Without the information obtained from physiologic testing, 11 percent of patients who may have benefited from surgery would not have been given this option, and 7 percent of patients could have potentially undergone unnecessary surgery. Transanal ultrasound is the study most likely to change a patient's management plan.

Augmented unilateral gluteoplasty with fascia lata graft in fecal incontinence.

BACKGROUND: This study was undertaken to evaluate the results of augmented unilateral gluteoplasty with fascia lata graft in patients with fecal incontinence due to congenital or neurologic disorders. METHODS: Between January 2000 and January 2001, we performed a prospective study of 11 patients with longstanding fecal incontinence (stage C3 according to Pescatori scoring system for fecal incontinence). The patients included one girl and 10 boys aged 5-19 years who had already undergone Swenson's operation for congenital megacolon (7 patients) or abdominoperineal pull-through for high imperforate anus (4 patients). Preoperative anorectal manometric studies (maximum resting pressure, maximum squeeze pressure, rectoanal inhibitory reflex and functional anal canal length), saline enema test and magnetic resonance imaging (MRI) studies were done. Unilateral gluteoplasty augmented with fascia lata graft was wrapped around the anal canal. Biofeedback retraining was started at the beginning of the fourth postoperative week. Patients were followed both objectively and subjectively for about 6-18 months. RESULTS: Eight of 11 patients (72.7%) were clinically improved, as shown by the change in incontinence score ( p=0.01). this was confirmed by the significant changes in manometric studies, functional anal canal length, rectoanal inhibitory reflex and saline enema test. MRI done one month postoperatively showed disruption in one patient. CONCLUSIONS: Unilateral gluteoplasty augmented with fascia lata graft leads to encouraging results in patients with end-stage anal incontinence due to irreversible damage to anal sphincter with less incidence of morbidity that could be related to tension on either the muscle flap or its neurovascular bundle.

Telephone vs. face-to-face biofeedback for fecal incontinence: comparison of two techniques in 239 patients.

PURPOSE: Biofeedback is an effective treatment for patients with fecal incontinence, yet little is known about how it works or the minimum regime necessary to provide clinical benefit. This study compares the effectiveness of a novel protocol of telephone-assisted biofeedback treatment for patients living in rural and remote areas with the standard face-to-face protocol for patients with fecal incontinence. METHODS: A new treatment program comprising an initial face-to-face assessment and treatment with transanal manometry and ultrasound biofeedback, followed by three treatments conducted via telephone and a final face-to-face assessment, was developed. Standard treatment involved five face-to-face treatment sessions with manometry and ultrasound. Patients from rural areas were offered the telephone-assisted treatment protocol. Data gathered prospectively included incontinence scores, a quality of life index, anal manometry, and external sphincter isometric and isotonic fatigue times. RESULTS: A total of 239 consecutive patients treated between July 2001 and July 2004 were enrolled. There were no significant differences in demographic details, past history, or pretreatment measures of the two groups. Forty-six of 55 patients (84 percent) treated with the telephone protocol and 129 of 184 (70 percent) treated by the standard technique completed treatment. There were substantial, significant improvements after treatment, including 54 percent mean improvement in patient's own rating of their incontinence in both groups; a mean decrease of 3.1 and 3.2 on the St. Mark's incontinence score (from 7.9 to 4.7 and 7.4 to 4.2 of 13) and relative improvements of 128 and 130 percent in the quality of life index (from 0.29 to 0.65 and 0.3 to 0.69 of 1) for the telephone-assisted and standard groups respectively. Importantly, there were no significant differences between the telephone-assisted or standard groups in any outcome. Of patients who completed treatment, 78 percent were better or much better. CONCLUSIONS: A less intensive regime of biofeedback seems to be equally effective as the standard intensive protocol. This finding adds weight to the evolving concept that the physical aspects of biofeedback treatment, such as manometry or ultrasound, may not be necessary in the treatment of most patients with fecal incontinence. This needs to be further tested in a randomized, controlled trial.

Is there a role for concomitant pelvic floor repair in patients with sphincter defects in the treatment of fecal incontinence?

BACKGROUND AND AIMS: More than half of all patients who undergo overlapping anal sphincter repair for fecal incontinence develop recurrent symptoms. Many have associated pelvic floor disorders that are not surgically addressed during sphincter repair. We evaluate the outcomes of combined overlapping anal sphincteroplasty and pelvic floor repair (PFR) vs. anterior sphincteroplasty alone in patients with concomitant sphincter and pelvic floor defects. PATIENTS AND METHODS: We reviewed all patients with concomitant defects who underwent surgery between February 1998 and August 2001. Patients were assessed preoperatively by anorectal manometry, pudendal nerve terminal motor latency, and endoanal ultrasound. The degree of continence was assessed both preoperatively and postoperatively using the Cleveland Clinic Florida fecal incontinence score. Postoperative success was defined as a score of <or=5, whereas postoperative quality of life was assessed by a standardized questionnaire. RESULTS: Twenty-eight patients (mean age 52.3 years) underwent overlapping anal sphincteroplasty. The mean follow-up was 33.8 months. Cleveland Clinic Florida scores postoperatively showed a significant improvement from preoperative values (14.2 vs 5.1, p<0.001). Seventeen patients (61%) underwent concomitant PFR with sphincteroplasty. Three patients (27%) without PFR and one patient (6%) with PFR underwent repeat sphincter repair due to worsening symptoms (p=0.15). Two patients with PFR and one patient without PFR ultimately had an ostomy due to a failed repair (p=0.66). Comparing patients with and without PFR, there was a trend toward higher success rates (71 vs. 45%) when pelvic prolapse issues were addressed during sphincter repair. CONCLUSION: Concomitant evaluation and repair of pelvic floor prolapse may be a clinically significant component of a successful anal sphincteroplasty for fecal incontinence but warrant further prospective evaluation.

History and examination in the assessment of patients with idiopathic fecal incontinence.

PURPOSE: This study was undertaken to identify those factors from the history and examination which might predict the pathophysiologic basis of idiopathic fecal incontinence. METHODS: In a prospective study of 237 patients with idiopathic fecal incontinence (female to male, 7:1.7; mean age, 54.8 years; median history, 3 years), history, examination, and anorectal physiology studies findings have been analyzed using contingency table analysis. RESULTS: In patients with idiopathic fecal incontinence, anorectal physiology studies have shown that a low maximum basal pressure (< 45 cm H2O) is predominantly attributable to internal and sphincter weakness, and low maximum squeezing pressure (< 76 cm H2O) is indicative of voluntary sphincter deficiency. In this study, a low maximum basal pressure is correlated with leakage, gaping of the anus on traction of the anal verge, and decreased resting tone on digital examination (all P < 0.05). A low maximum squeezing pressure is correlated with incontinence en route to the lavatory, urgency, both stress and urge incontinence of urine, reduced voluntary contraction in the external anal sphincter and puborectalis on digital examination, and a reduced or absent anorectal angle (all P < 0.05). CONCLUSION: This study has shown that an informed history and digital examination can predict the manometric findings of specialist anorectal physiology studies.

[Therapy of fecal incontinence in elderly patients: Study of a home biofeedback training program].

UNLABELLED: The increased prevalence of urinary and fecal incontinence is one of the most important factors in the loss of independence and mobility in the elderly population. It is also one of the major reasons for elderly people to give up their household and move into a nursing home. Anorectal biofeedback therapy is a very effective treatment for fecal incontinence. However, due to the increased immobility of elderly people, ambulatory biofeedback training programs which require the participants to leave their homes and travel to the next available outpatient clinic on a regular basis, especially when depending on public transportation, may prove particularly difficult for elderly, incontinent subjects. Supervised home biofeedback training programs may offer an alternative for those patients, who are motivated enough and not mentally impaired. Two different age groups of women (between 49 and 63; and between 65 and 78 years old) suffering from fecal incontinence due to external anal sphincter impairment, received a supervised home biofeedback program, after extensive anorectal diagnostics including manometry. The program focused on improving voluntary sphincter contraction. After an average of 9 months, anorectal manometry was repeated, and anal resting and squeeze pressure as well as minimal rectal perception threshold were determined. There was no effect on anal resting pressure and rectal perception. However, anal maximum squeeze pressure as well as squeeze pressure over 10 s was substantially increased with no difference between the age groups. CONCLUSION: Supervised home biofeedback for sphincter insufficiency was effective in improving the voluntary contraction of the anorectum in both age groups. Therefore, biofeedback home training programs may offer an alternative to ambulatory programs for those individuals, who are not mobile enough to regularly attend an outpatient clinic.

Scintigraphic assessment of retrograde colonic washout in fecal incontinence and constipation.

PURPOSE: This study aimed to evaluate the colorectal luminal transport obtained by retrograde colonic washout with a new scintigraphic technique. METHODS: Nineteen patients (5 with spinal cord lesion, 6 with idiopathic fecal incontinence, and 8 with idiopathic constipation) treated with retrograde colonic washout took indium-111-labeled polystyrene pellets to label the bowel contents. Technetium-99m-diethylene-triamine-pentaacetic acid was mixed with the irrigation fluid to assess its extent within the colorectum. Scintigraphy was performed before and after a standardized washout procedure. The colorectum was divided into four segments: the cecum and ascending colon, the transverse colon, the descending colon, and the rectosigmoid. Assuming ordered evacuation of the colorectum, the contribution of each colonic segment to the total evacuation was expressed in percent of the original segmental counts. The contributions of each segment were summed to reach a total defecation score (range, 0-400), and directional segmental transports were estimated. RESULTS: The defecation score in patients with idiopathic constipation (median, 59; range, 21-130) differed significantly (P < 0.05) from the scores in those with spinal cord lesions (median, 204; range, 108-323) and idiopathic fecal incontinence (median, 188; range, 155-234). Thus, patients with spinal cord lesion or idiopathic fecal incontinence were able to empty most of the rectosigmoid and most of the descending colon, but those with idiopathic constipation could only empty 59 percent of the rectosigmoid. The irrigation fluid on average reached a point just beyond the right colic flexure that correlated with the defecation score (r(2) = 0.58, P < 0.001). CONCLUSION: The effect of retrograde colonic washout was significantly better in spinal cord lesion and idiopathic fecal incontinence than in idiopathic constipation, and its effect correlated with the extent to which the irrigation fluid had entered the colorectum.

The SECCA procedure: a new therapy for treatment of fecal incontinence.

The SECCA (Curon Medical, Freemont, CA USA) device delivers temperature-controlled radiofrequency (RF) energy to the anorectal junction to treat fecal incontinence. The procedure is performed as an outpatient either in the endoscopy suite or ambulatory surgery center. After appropriate local block, the SECCA device is then inserted into the anal canal and submucosal RF energy is delivered circumferentially to the anorectal junction. A pilot trial in Mexico on 10 patients demonstrated a significant improvement in Cleveland Clinic Florida Fecal Incontinence Scores (CCF-FIS) from a pre-treatment score of 13.5 to 12-month post-treatment score of 3.8. These patients continued to have significantly improved continence with an average CCF-FIS of 7.3 at 24-month follow up. A multi-center, institutional review board-approved, open label, prospective trial that evaluates the efficacy and safety of the SECCA procedure has been completed in the United States (U.S.). Five centers prospectively enrolled 50 patients with greater than or equal to 3 months of weekly fecal incontinence who also had failed either medical or surgical interventions. Patients underwent anoscopy, anorectal manometry (ARM), endoanal ultrasound (EAUS), and pudendal nerve terminal motor latency (PNTML) at 0 and 6 months. The CCF-FIS scale, fecal incontinence-related quality of life score (FIQL), and SF-36 were administered at 0, 3, and 6 months. After conscious sedation and local perianal block, RF energy was delivered by way of the SECCA device. At 6 months, the mean CCF-FI score improved significantly (14.5 to 11.1, p<0.0001). All FIQL parameters improved: lifestyle (2.5 to 3.1, p=0.0001), coping (1.9 to 2.3, p=0.005), depression (2.8 to 3.1, p=0.0008), embarrassment (1.9 to 2.5, p<0.0001). Sixty-percent (n=30) of the patients improved after therapy, with 70% resolution of their symptoms. The SF-36 mental composite score (45.3 to 48.3, p=0.06) and social function sub-score (64.0 to 77.3, p=0.003) improved. No changes occurred in ARM, EAUS, or PNTML. Two major complications included two mucosal ulcerations. From these data, the authors concluded that RF energy delivered for treatment of FI safely improves CCF-FIS, FIQL, and quality of life.
