[Morpho-functional radiologic evaluation of ileal reservoirs].

Nine patients (4 males and 5 females) have been treated by proctocolectomy with ileal pouch "reservoir". Defecography has been performed. Five patients have been examined by defecography before and four after closure of a loop ileostomy performed to cover healing of the pouch and ileoanal anastomoses. Pouch's evacuation is often inadequate in "S" shaped reservoir (Parks), but postoperative complications are infrequent. Pouch's evacuation is often total in "J" shaped reservoir (Utsunomiya), but post-operative complications are possible.

[Restorative proctocolectomy. A morphological-functional study by computed tomography with coronal scans].

Restorative proctocolectomy with ileal pouch has become the surgical treatment of choice for patients with ulcerative colitis and familial polyposis of the colon. Defecography is the radiologic technique commonly used to obtain detailed information on function and morphology of the ileal pouch, but it fails to depict the pelvis. Computed Tomography (CT), with coronal images only was used to examine 10 patients with ulcerative colitis, submitted to restorative proctocolectomy. Coronal CT, yielding a panoramic view of the pelvis, represent an effective alternative technique to defecography. In fact, the two techniques provide comparable information relative to the ileal pouch; coronal CT also depicts the possible thickening of pouch walls and of pelvic fat tissue. Coronal CT also depicts the continence of ileo-anal and ileo-ileal anastomoses and the functional changes of the perineal muscles at rest and during squeezing. Coronal CT images allow easy and clear detection of such major postoperative complications as pelvic inflammation and fistulae (less frequently stenosis or dehiscences of the anastomosis).

Anismus and biofeedback: who benefits?

BACKGROUND: Biofeedback is the main treatment for dyschezia in patients with anismus, but retraining may fail because of the frequent association of pelvirectal disorders with anismus. We set out to identify indices of biofeedback failure in the treatment of anismus. PATIENTS AND METHODS: From May 1990 to May 1993, 27 patients (20 women and seven men; median age 46 years) with anismus in which dyschezia was not improved by laxative agents were enrolled in a biofeedback retraining programme. All patients underwent proctologic examination, anal manometry and defecography. Anismus was defined as an increase in anal pressure during attempted defecation in conjunction with an impairment of rectal emptying as assessed using an objective test (barium paste expulsion). Associated disorders were encountered frequently. These included abnormal perineal descent (22 cases), large rectocoele (12 cases), high-grade rectal prolapse (six cases), abnormally high anal canal pressures at rest (seven cases) and abnormal rectal response to inflation (20 cases). Anismus was the sole abnormality in 12 patients when perineal descent, low-grade prolapse and abnormal rectal sensations were not taken into account. RESULTS: Biofeedback retraining did not suppress dyschezia in 13 out of 27 patients. Neither associated disorders (rectocoele, rectal prolapse, abnormal perineal descent, anal pressure and abnormalities of rectal sensation) nor a relevant past history (hysterectomy, laxative abuse, use of antidepressive agents) were encountered more frequently in these 13 patients than in the other 14. The duration of symptoms before treatment was significantly longer in the group unresponsive to biofeedback retraining (81 +/- 61 compared with 33 +/- 34 months for the responsive group, P < 0.01), but the total duration of symptoms and the number of retraining sessions attended did not differ significantly between the two groups. CONCLUSIONS: (1) Extensive examination (defecography and manometry) before biofeedback retraining of anismus is not mandatory because the failure of retraining (48%) is not related to the presence of associated pelvirectal disorders. (2) A long past history of dyschezia seems to provide an index of the failure of biofeedback retraining.

[Anorectal functional study. The state of the art].

Disturbances of anal continence and evacuation are frequent. Numerous techniques are now available to measure anorectal function. There is also a better understanding of the anatomy and physiology of the pelvic floor which has a major role in anorectal function. ANORECTAL MANOMETRY. Manometry of the anal canal is an index of the resistance of sphincters to the passage of faeces. Resting pressure is due mainly to the internal anal sphincter whereas voluntary contraction is due mainly to the external anal sphincter. Anorectal manometry is essential in measuring the length of the anal canal and in establishing the presence of the rectoanal inhibitory reflex. Several techniques are employed to evaluate anorectal manometry which is useful in the investigation of patients with faecal incontinence and constipation. PUDENDAL LATENCIES: Pudendal latencies are valuable in the study of the innervation of the external anal sphincter. Pudendal latencies are measured thanks to the stimulation of the S2-S4 nerves lying in the proximity of the ischial spine through the use of a special glove (St Mark's glove). Prolonged pudendal latencies are typical of neurogenic faecal incontinence but it can be brought about by childbirth, rectal prolapse, obstructed defecation and old age. ELECTROMYOGRAPHY. Electromyography is useful in the study of the function of the pelvic floor. This technique can be performed with single fibre needles which make it possible to measure the action potentials and the fibre density of the muscular fibres. Fibre density is raised in neurogenic faecal incontinence and the action potentials are polyphasic in this condition. Concentric needles are employed to map the anal sphincters and this is useful for evaluating the extent of the damage caused by traumatic events like a third degree tear. ANAL ENDOSONOGRAPHY. Anal ultrasound is very effective in the study of the morphology of the anal sphincters and it requires a rectal probe fitted with a 7-MHz transducer. It is as accurate as electromyography in evaluating the damage to the anal sphincters but it is not painful and it is more acceptable to the patient. DEFECOGRAPHY. This radiological test is a dynamic study of the pelvic floor during defecation. It is very useful for investigating the function and the morphology of the rectum and the pelvic floor during defecation. Important parameters like: the anorectal angle, the opening of the anal canal, the position of the pelvic floor and the descent of the perineum can be evaluated with this test. Defecography is useful in the study of patients with rectal prolapse and constipation. CONCLUSION. All these tests provide extremely useful information on the pelvic floor and are reproducible. They can be of great help in evaluating patients with pelvic floor disorders but they are no substitute for clinical judgement.

[Anorectal asynchronism. Clinical, manometric and therapeutic data].

OBJECTIVES: Anorectal asynchronism is a frequent and unrecognized cause of terminal constipation. The aim of this study was to describe clinical and instrumental findings, and results of biofeedback therapy. METHODS: From 1987 to 1991, 18 patients with anorectal asynchronism were studied then treated by biofeedback training. RESULTS: We found high rates of pelvic and perineal trauma (77.7%), of psychogenic factors (6.5%), of urinary incontinence (27.8%). The manometrical study confirmed puborectalis paradoxical contraction during defecation straining, and all the patients could not expel a rectal balloon containing 50 ml of air; non-specific manometrical abnormality was found in 44.5% patients. Excessive stamp of puborectalis muscle was always found at defecography; 77.7% of the patients had incomplete rectal evacuation, and 61.1% had an associated pelvic floor disorder. Biofeedback training was successful, and 88.9% of the patients were cured by 5 or 6 sessions. There was no predictive parameter in our study, but recovery rate seemed to be lower for patients from 45 to 55 years old. CONCLUSION: The diagnosis of the anorectal asynchronism is easily made with manometry and defecography. Treatment with biofeedback gives very good results in almost all patients.

Characterization of swallowing and defecation in Parkinson's disease.

UNLABELLED: Despite the high prevalence of Parkinson's disease, the pathophysiology of its gastrointestinal symptoms remains poorly understood. OBJECTIVES: to evaluate swallowing and defecatory function in patients with Parkinson's disease and age- and sex-matched controls and to correlate objective findings with subjective symptoms. METHODS: The following studies were performed on 13 patients with Parkinson's disease and seven controls: extrapyramidal function assessment, gastrointestinal symptom survey, videoesophagram, colon transit study, defecography, and anorectal manometry. RESULTS: Abnormal salivation (frequency, %, control vs. Parkinson's disease: 14 vs. 77, p < 0.05), dysphagia (14 vs. 77, p < 0.05), constipation (14 vs. 31, p < 0.05), and defecatory dysfunction (29 vs. 77, p < 0.05) were more common among Parkinsonian patients. However, videoesophagographic abnormalities were equally common in both groups. Colon transit time was significantly prolonged in the Parkinson's disease group. Altered puborectalis function was noted on defecography in 31% of Parkinson's disease subjects, but in none of the controls (p < 0.05). Anorectal manometry identified several abnormalities in the Parkinson's disease group, which included decreased basal anal sphincter pressures, prominent phasic fluctuations on squeeze, and a hyper-contractile external sphincter response to the rectosphincteric reflex. Many patients exhibited both slow transit and manometric abnormalities, and symptoms were poor predictors of test results. CONCLUSION: In this group of patients with mild to moderate Parkinson's disease, videoesophagographic abnormalities were not confined to the patients with Parkinson's disease. Studies of colonic and anorectal function, in contrast, identified a number of abnormalities. Therefore, colonic and anorectal dysfunction appears to be an early gastrointestinal manifestation of Parkinson's disease, and may represent the direct involvement of the gut by this disease process.

Anal endosonographic findings in patients with obstructed defecation.

Anal endosonography, including measurements of anal sphincter size, was performed in 16 patients with obstructed defecation. The findings were compared with those at defecography and anal manometry. Patients with rectocele and intussusception had a normal endosonographic appearance. One patient with puborectalic spasm had normal sonography. There was no correlation between sphincter size and anal manometry. The external sphincter muscle was thicker and the cross-sectional area larger in patients with obstructed defecation than in healthy controls (p < 0.05). Two patients with sphincter spasm and impaired rectal emptying at defecography had clearly thickened internal sphincters which may be the cause of their defecatory disorder. Three patients with previous anal dilatation or hemorrhoidectomy had sphincteric defects. Anal endosonography may be considered in patients with obstructed defecation to identify patients with internal sphincter hypertrophy.

Results of biofeedback in constipated patients: a prospective study.

PURPOSE: The aims of this study were to assess the results of biofeedback treatment in constipated patients and to identify variables that might be used to predict the outcome. METHOD: Twenty-eight patients (5 men; median age, 46 (range, 22-72) years) with any degree of paradoxical activation measured with thin hook needle electromyography in the external sphincter or puborectalis muscle were included. The symptom duration varied between 1 and 30 (median, 9) years. The patients had eight outpatient training sessions with electromyography-based audiovisual feedback. All patients were followed up prospectively with a validated bowel function questionnaire from which a symptom index was created. RESULTS: At three months, nine patients had no improvement and underwent other treatments. The remaining 19 patients were followed up for a median of 14 (range, 12-34) months. Twelve patients (43 percent) stated they had improved rectal emptying. A good result was associated with increased stool frequency (P < 0.05), improved symptom index (P < 0.01), and reduction of laxative use (P < 0.05). A long symptom duration, a high pretreatment symptom index, and laxative use were related to a poor result (P < 0.01-0.05). The improved group had less perineal descent (P < 0.05), and a prominent puborectalis impression on defecography tended to be more common (P = 0.06). CONCLUSION: With the use of wide inclusion criteria, biofeedback was successful in 43 percent of patients, with a treatment effect lasting at least one year. The results suggest that biofeedback should be used as the initial treatment of constipated patients with a paradoxical puborectalis contraction.

Electromyography of the pelvic floor musculature in the assessment of obstructed defecation symptoms.

PURPOSE: The purpose of this study was to use electromyography to examine the behavior of the external sphincter, puborectalis muscle, and pubococcygeus muscle during attempted defecation in patients with symptoms of obstructed defecation and in normal subjects to highlight differences of clinical significance. METHODS: A total of 35 patients (31 females) aged 20 to 80 (mean, 53.7 +/- 13.3) years with unprepared bowel who had normal colon transit time and obstructed defecation symptoms and 12 voluntary control subjects (7 females) aged 23 to 68 (mean, 48 +/- 11.5) years underwent an electromyography evaluation of the activity of the external sphincter, puborectalis muscle, and pubococcygeus muscle during attempted defecation. The patients were also examined in separate sessions with defecography and anal manometry. RESULTS: During attempted defecation, puborectalis muscle and external sphincter always reacted in the same manner. When evaluated with pubococcygeus muscle, three main patterns of activity were observed either in patients or in controls: 1) coordinated activation pattern; 2) coordinated inhibition pattern; and 3) uncoordinated or equivocal pattern: activation of pubococcygeus muscle with inhibition of puborectalis muscle/external sphincter, activation followed by inhibition of the three muscles, and activation followed by inhibition of pubococcygeus muscle and no change in the others. We never observed activation of puborectalis muscle/external sphincter concomitant with inhibition of pubococcygeus muscle. The inhibitory coordinated pattern occurred significantly (P = 0.01) more frequently in controls than in patients. These subjects also presented a significantly (P = 0.01) lower frequency of pubococcygeus muscle inhibition. CONCLUSIONS: Either activation or inhibition appears as a physiological behavior, possibly adopted in different circumstances, of the pelvic floor muscles during attempted defecation. The higher prevalence of coordinated inhibitory patterns in normal subjects and the lower frequency of pubococcygeus muscle inhibition in patients with symptoms of obstructed defecation, however, suggests that a loss of inhibition capacity progressing from pubococcygeus muscle to puborectalis muscle/external sphincter muscles could determine the insurgence of obstructed defecation symptoms in some subjects, who should therefore benefit from biofeedback retraining aimed at reacquisition of the inhibition capacity of all muscles of the pelvic floor during defecation.

Clinical value of symptom assessment in patients with constipation.

PURPOSE: This study was designed to evaluate symptoms and clinical findings in a prospective series of patients with chronic constipation. METHODS: A total of 155 consecutive patients with intractable constipation underwent detailed symptom registration, anorectal manometry, electromyography, colonic transit time measurement, and defecography. RESULTS: All investigations were completed by 134 patients (112 females) with a median age of 52 (range, 17-79) years. Whole-gut transit time was delayed in 55 patients (41 percent), pelvic floor dysfunction was diagnosed in 59 patients (44 percent), but in 35 percent of patients both transit time and pelvic floor function were found to be normal. Three symptoms were shown to have an independent value for the diagnosis of slow-transit constipation. Patients with slow transit more often reported two or fewer stools per week (84 vs. 46 percent), laxative dependence (87 vs. 44 percent), and a history of constipation since childhood (58 vs. 22 percent) than did those with normal transit. Pelvic floor dysfunction was associated with a higher prevalence of backache (53 vs. 33 percent) and a lower prevalence of normal stool frequency (19 vs. 36 percent), heartburn (12 vs. 27 percent), and a history of anorectal surgery (7 vs. 21 percent) compared with those with normal pelvic floor function. All four symptoms retained an independent value in the logistic regression analysis for pelvic floor dysfunction. Two symptoms characterized the group with normal transit and normal pelvic floor function: normal stool frequency and alternating diarrhea and constipation. CONCLUSIONS: Symptoms are good predictors of transit time but poorer predictors of pelvic floor function in patients with constipation.

Is rectal intussusception a cause of idiopathic incontinence?

PURPOSE: The cause of rectal intussusception in patients primarily dominated by symptoms of anal incontinence has not been fully elucidated, especially for patients with idiopathic incontinence. METHODS: Between 1991 and 1996, 51 patients referred with a diagnosis of idiopathic incontinence were prospectively evaluated by standard questionnaire, clinical examination, defecography, and anal manometry. Fourteen female patients were identified with rectal intussusception and were treated by transabdominal rectopexy. Postoperatively, clinical assessment and anal manometry were performed at regular intervals. RESULTS: Continence was improved after rectopexy (P < 0.01). The postoperative increases in the anal resting pressure, maximum squeeze pressure, and maximum tolerated volume were not statistically significant. CONCLUSIONS: Rectopexy improved anal incontinence in patients with rectal intussusception. The cause of rectal intussusception in anal incontinence could not be explained by functional improvement of the internal anal sphincter tone or an increase in the maximum tolerated volume. Rectal intussusception may be a cause of idiopathic incontinence in patients; however, larger prospective studies are required to support this concept.

Analysis of patients with poor outcome of rectocele repair.

PURPOSE: The aim of the present study was to analyze the prognostic value of clinical data and physiologic tests in patients undergoing rectocele repair for obstructed defecation. METHODS: Between 1988 and 1996, 89 consecutive female patients with obstructed defecation caused by a rectocele were enrolled in the study. Median age at time of presentation was 55 (range, 35-81) years. All patients underwent a combined transvaginal and transanal rectocele repair. End evaluation to assess long-term results was performed by an independent observer after a median duration of follow up of 52 (range, 12-92) months. The presence of the following five symptoms was evaluated: prolonged and unsuccessful straining at stool, feelings of incomplete evacuation, manual assistance during defecation, false urge to defecate, and a stool frequency of less than three times per week. When none or just one of these symptoms was present, outcome of rectocele repair was considered successful. The outcome was considered as a failure when two or more of these symptoms were recorded. Furthermore, all patients were asked to score the outcome of their operations as excellent, good, moderate, or poor. Clinical data and the results of physiologic tests obtained in patients with a poor outcome of surgery were compared with those obtained in patients with a successful outcome. RESULTS: Objective outcome of rectocele repair, based on the presence of symptoms, was found to be successful in 63 (71 percent) patients. Sixty-one patients considered outcome of surgery excellent or good (69 percent). Graded subjective outcomes between the two groups showed significantly better grades in cases of success. Duration of symptoms, number of symptoms, age, parity, and previous hysterectomy had no influence on the final outcome of surgery. Defecographic parameters, such as size of the rectocele, barium trapping in the rectocele, poor rectal evacuation, or intussusception, had no prognostic value. Signs of anismus based on defecography, electromyography, and balloon-expulsion studies did not influence outcome of surgery. The presence of symptoms such as defecation frequency, manual assistance, severe straining, false urge to defecate, or feelings of incomplete evacuation had no impact on the outcome. However, in patients without a daily urge to defecate or with a stool frequency of less than once per week, results of rectocele repair were significantly worse than in patients with a daily urge to defecate or a defecation frequency of more than once per week or both. In 14 of 26 patients with a poor outcome, colonic transit studies were performed. A delayed passage was observed throughout the entire colon in seven patients, in the left part of the colon and the rectosigmoid colon in four patients, and in the rectosigmoid colon in one patient. In two patients colonic transit was normal. CONCLUSIONS: Combined transvaginal and transanal rectocele repair is beneficial for the majority of patients with obstructed defecation. In patients without a daily urge to defecate or a stool frequency of less than once per week, indicating colonic malfunctioning, the outcome of rectocele repair seems to be poor.

Detection of a rectocele-like prolapse in the colonic J-pouch using pouchography: cause or effect of evacuation difficulties?

The functional outcome after a low anterior resection for rectal cancer is improved by a colonic J-pouch reconstruction. One functional problem with J-pouches is difficulty in evacuation, which is more common with large reconstructions. Since rectoceles are common findings on defecography in patients with evacuation difficulties, we proposed that a rectocele-like prolapse may be thus found in patients with large J-pouches. Pouchography was used to identify a rectocele-like prolapse (RP) in 26 patients with a 10-cm J-pouch (10-J group) and 27 patients with a 5-cm J-pouch (5-J group). Pouchography was performed at 3 months, 1 year, and 2 years after surgery. Functional assessments were performed 1 year postoperatively. Clinical function was evaluated using a questionnaire. The evacuation function was evaluated by the balloon expulsion and saline evacuation test. No patients had an RP at 3 months or 1 year after surgery. An RP was significantly more common in the 10-J group than in the 5-J group at 2 years after surgery (P = 0.0374). An evacuation difficulty was significantly more common in the 10-J group than in the 5-J group. The evacuation function in the 10-J group was also significantly inferior to that in the 5-J group. An RP appearing 2 years after surgery is more common in patients with evacuation difficulties and large colonic J-pouch reconstructions.

[Obstructed defecation].

Adequate therapy of obstructed defecation (pelvic outlet obstruction) is often challenging, as the etiology and clinical symptoms include a wide range of disorders. Standardized diagnostic assessment has to differentiate between obstructed defecation caused by either pelvic outlet obstruction or slow transit constipation. Additionally, morphologic changes of colon, rectum, or the pelvic floor have to be separated from functional disorders. Providing defecography or dynamic MR of the pelvic floor, common causes of outlet obstruction such as sigmoidoceles, in which surgery is indicated, and rectal prolapse can be diagnosed with high accuracy. However, the diagnosis and therapeutic options in symptomatic rectocele and intussusception are controversial. Patients with functional disorders such as rectoanal dyssynergia are candidates for conservative treatment (biofeedback). To identify patients who will benefit from surgery for obstructed defecation, careful patient selection remains the crucial issue in diagnostic assessment.

[Differential diagnosis in descending perineum syndrome].

Clinical symptoms in descending perineum syndrome show considerable variations, ranging from obstructed defecation to combined fecal and urinary incontinence and including different types of prolapse. Differential diagnosis has to compete with this complexity. Common pelvic floor disorders associated with descending perineum are rectocele, rectal prolapse, enterocele, and sigmoidocele. Standardized diagnostic tools include detailed history and clinical examination with proctorectoscopy as well as anorectal manometry, endoanal ultrasound, defecography, and dynamic MR of the pelvic floor. The diagnosis and proposed therapy have to be developed within an interdisciplinary concept.

The current role of imaging techniques in faecal incontinence.

Faecal incontinence is a common multifactorial disorder. Major causes of faecal incontinence are related to vaginal delivery and prior anorectal surgery. In addition to medical history and physical examination, several anorectal functional tests and imaging techniques can be used to assess the underlying pathophysiology and to guide treatment planning in faecal incontinent patients. Anorectal functional tests provide functional information, but the potential strength comes from combining test results. Imaging techniques, including defecography, endoanal sonography, and magnetic resonance (MR) imaging, provide structural information about the anorectal region with a direct clinical impact. The major role of imaging techniques in faecal incontinence is visualising the structural and functional integrity of the anal sphincter complex. Both two-dimensional endoanal sonography and endoanal MR imaging are accurate tools to depict anal sphincter defects. The major advantage of endoanal MR imaging is the accurate demonstration of external anal sphincter atrophy. Recent studies have suggested that external phased array MR imaging and three-dimensional endoanal sonography are also valuable tools in the diagnostic work up of faecal incontinence. Decisions about the preferred technique will mainly be determined by availability and local expertise. This article demonstrates the current role of tests, predominantly imaging tests, in the diagnostic work up of faecal incontinence.

Role of pelvicography and colpocystodefecography in diagnosis of outlet obstructive constipation.

AIMS: The aim was to research the changes in pelvic floor morphology and corresponding visceras in patients with outlet obstructive constipation (OOC). PATIENTS AND METHODS: Thirty-eight patients with OOC and 12 healthy volunteers were enrolled in this study. With simultaneous pelvicography and colpocystodefecography (PCCD), including pelvicography, vaginal opacification, voiding cystography and defecography, pelvic floor morphology was observed and the anorectal angle, the level of the perineum, peritoneum and bladder were measured. RESULTS: Thirty-seven cases of internal rectal prolapse (IRP), 5 cases of rectocele (RC) and 5 cases of spastic pelvic floor syndrome SPFS were diagnosed by PCCD. 12 IRP, 4 RC and 1 SPFS were detected by common physical examination. All of these were confirmed by PCCD. Moreover, PCCD found 9 pelvic floor hernia or peritoneoceles, 6 cystoceles, 3 descending perineum syndromes and 10 uterine prolapses. Compared with controls, OOC patients had a significantly large anorectal angle during defecation, abnormal descending of the perineum at rest and during defecation, and a deep pouch of Douglas during defecation. Some patients with urinary system symptoms may have had an abnormal descent of the bladder during rest and defecation. CONCLUSION: Simultaneous PCCD has a higher positive ratio than the common physical examination in diagnosing IRP and RC, and provides information for the diagnosis of pelvic floor hernia or peritoneocele, cystocele or uterine prolapse. PCCD is helpful in the selection of a proper surgical procedure.

Outcome of overlapping anal sphincter repair after 3 months and after a mean of 80 months.

BACKGROUND: The aim of this study was to determine the functional results of anal sphincter repair after a long follow-up (mean 80.1 months). METHODS: In the period 1990-2002, 65 sphincter repairs were performed. Obstetric trauma was the cause of incontinence in 72.3% cases, fistulotomy in 13.8%, nonspecific trauma in 9.2%, and war injury in 4.6%. At the time of surgery, 12 patients had undergone an urgent stoma procedure. In all cases, anal manometry, electromyography, and defecography were performed. The severity of incontinence was evaluated preoperatively using the Wexner score system. Anterior sphincteroplasty was performed in 52 cases, lateral in 9 cases, and posterior in 4 cases. RESULTS: The results were determined according to the Wexner score system and the Browning-Parks scale. The Wexner score was calculated 3 months after operation and during every follow-up visit. Preoperative scores and those at the first and last follow-up visits were analyzed. Three months after operation excellent results were achieved in 55.5%, good in 18.5%, fair in 16.9%, and poor in 9.2% patients. After follow-up (mean 80.1 months), 26.8% had excellent results, 21.4% had good results, 12.5% had fair results, and 39.3% of patients had a poor outcome. Results determined by the Wexner score system improved from 17.8 preoperatively to 3.6 three months after operation, but deteriorated over time to 6.3 after longer follow-up (p<0.001). CONCLUSION: Overlapping sphincter repair provides satisfactory results in more than two-thirds of patients initially, but the results tend to worsen over time and are satisfactory in half of patients after longer follow-up.
