The anal sphincter force in the evaluation of postoperative imperforate anus.

Eight-four children, all of whom had imperforate anus, were evaluated by measuring the anal sphincter force (ASF). Sixty-three were boys, 46 of whom had a high imperforate anus and 17 of whom had the low anomaly. There were 7 girls with cloacal malformations, 7 girls with high type and 7 with low type of malformation. In all the boys with a high imperforate anus the ASF ranged from 50 to 300 g. Those boys with a low type had an average ASF of 513 g. Normal values vary from 480 to 600 g. Twenty-five of the boys with a high imperforate anus had undergone posterior sagittal anorectoplasty and none were clinically continent. Their ASF measurements were lower than in patients with spina bifida. Patients with a low anomaly, both boys and girls, were continent and had high ASF readings. The ASF is a simple, inexpensive, and objective measurement of fecal incontinence when this is the consequence of muscular inadequacy. A reproducible quantification is now available to compare results of different operations and different centres.

Surgical implications of genitourinary tract anomalies in patients with imperforate anus.

Genitourinary anomalies in patients with imperforate anus are a frequent source of significant morbidity. We report a retrospective study of 64 genitourinary procedures performed on 23 patients. Renal, collecting system, bladder and perineal anomalies were encountered in 65%, 83%, 87% and 65% of these complex cases, respectively. A total of 70% of the patients required intermittent catheterization due to bladder dysfunction. Surgical alternatives, complications of management and functional outcomes are reviewed in detail. Genitourinary reconstruction is best undertaken as an integral part of imperforate anus reconstruction. Failure to do so results in the loss of surgical alternatives, unnecessary reoperative procedures and compromised outcomes.

Augmented-pressure colostogram in imperforate anus with fistula.

Most newborns with imperforate anus, except for those with very low varieties, undergo a diverting colostomy performed in the postnatal period, with definitive surgical repair at a later age. Accurate demonstration of the anatomy of any associated fistula between the rectum and urogenital tract is essential for optimal surgical management. An augmented-pressure distal segment colostogram is recommended prior to definitive repair, both to confirm the level of rectal atresia and to define any associated fistulous communication. We report a case of high imperforate anus with rectourethral fistula in which the fistulous tract was not identified on the conventional contrast colostogram but was readily delineated when an augmented-pressure modification of the technique was utilized. The technical aspects of augmented-pressure colostography are presented.

Imperforate anus: an unusual presentation of a common disease.

Imperforate anus is a common problem facing the pediatric surgeon. Most cases of imperforate anus are discovered at birth during the initial physical examination and are corrected early. The pediatric population also accounts for 80% of all cases of ingested foreign bodies. Most of these pass through spontaneously and the treatment is observation. In this article, we present the case of a seven-month-old child in whom failure to pass a swallowed coin led to the diagnosis of imperforate anus. This case illustrates an uncommon presentation of a common disorder and emphasizes the importance of vigilance and careful physical examination in the newborn.

Immediate and long-term results of surgical management of low imperforate anus in girls.

BACKGROUND: The majority of girls with imperforate anus are reported to have a malformation of the low variety. Despite this, much of the literature has focused on the more complex, high lesions. METHODS: This study reviews our experience with 44 girls with low imperforate anus from a 22-year period. RESULTS: The incidence of associated anomalies was 61%, which is higher than generally reported. All patients in the study had anal fistulae. Fifty-seven percent had perineal fistulae, 23% had fourchette fistulae, and 20% had vestibular fistulae. Cutback anoplasty was performed in 55%, Potts transfer anoplasty was used in 27%, and 18% of patients were treated with either limited posterior sagittal anorectoplasty or anterior sagittal anorectoplasty. Surgical complications were uncommon. Long-term follow-up was carried out by telephone survey. This showed 89% of the girls to be successfully toilet trained. However, 47% of patients experience at least occasional soilage or episodic fecal incontinence. CONCLUSIONS: Low imperforate anus can be successfully treated using a variety of procedures without colostomy. Most girls with low imperforate anus are successfully toilet trained, but problems with continence persist in a significant number of these patients.

Percutaneous transperineal pouch localization in low imperforate anus: a new approach.

Patients who have an imperforate anus with associated infralevator, or low rectal pouch, are candidates for a perineal anoplasty. However, in the absence of a perineal fistula, intraoperative localization and isolation of the rectal pouch can be difficult. We have developed a technique to facilitate isolation and dissection of the rectal pouch for perineal anoplasty in patients with a low imperforate anus who do not have a perineal fistula present. Pouch localization is carried out preoperatively by fluoroscopic percutaneous transperineal placement of a Fogarty embolectomy catheter through the center of the anal wink. We have used this technique successfully in four consecutive patients who had a low imperforate anus, in the absence of a perineal fistula, with the pouches 1.0 to 1.5 cm from the perineum. Results have been excellent, and the dissection of the rectal pouch was facilitated greatly by the presence of the inflated Fogarty balloon.

Recurrent epididymo-orchitis caused by posterior urethral valve associated with imperforate anus.

Epididymo-orchitis is an uncommon complication of imperforate anus. A 14-year-old boy who received surgical repair for imperforate anus was diagnosed with right epididymo-orchitis. Intravenous pyelography showed a right solitary kidney. Posterior urethral valve, reflux of contrast medium to the ejaculatory duct and incomplete duplicate urethra were suspected from voiding cystourethrography. Valve ablation was performed to prevent the recurrence of epididymo-orchitis. Improvement of urinary force was achieved and the patient has been free of recurrence during a 2-year follow up. For the patient with imperforate anus, we should evaluate not only anorectal function, but also the genitourinary tract in order to preserve renal function and fertility.

[Urodynamic investigations of bladder disturbances in imperforate anus and Hirschsprung's disease) (author's transl)].

104 children with imperforate anus and 68 children with megacolon congenitum were subjected to careful analysis in respect of postoperative incontinence of urine. This was observed in 20 patients with imperforate anus (19.2%) and 15 patients with Hirschsprung's disease (22%). In children with imperforate anus urine incontinence showed a slight tendency only to spontaneous cure. For example, 19.1% of the children with imperforate anus still showed signs of incontinence 11 years after the first operation. On the other hand, there was often a spontaneous cure of incontinence of urine in children with Hirschsprung's disease, so that 5.8% only of the patients had incontinence after the same period. The causes of incontinence are of a multifactorial nature. Rectourethral fistulas, which can damage the sphincter vesicae externus, play an important part. This is likewise true of sequel operations in the pelvis minor with iatrogenic lesions of the sacral nerve fibres; of associate malformations of the urogenital tract and of the vertebral column; and of chronic relapsing infections of the urinary tract caused by an accompanying encopresis (incontinence of faeces).

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

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

Tethered cord and associated vertebral anomalies in children and infants with imperforate anus: evaluation with MR imaging and plain radiography.

PURPOSE: To evaluate in children and infants with imperforate anus the prevalence and types of occult myelodysplasia that may result in tethered cord and the association of these lesions with vertebral anomalies. MATERIALS AND METHODS: Records and images were retrospectively reviewed in 86 patients who underwent spine magnetic resonance imaging and had either low-level imperforate anus (n = 30), intermediate-level imperforate anus (n = 15), or high-level imperforate anus (n = 41). RESULTS: Thirty-one of 86 patients (36%) had occult myelodysplasia suggestive of tethered cord (27% of all patients with low-, 33% of all patients with intermediate-, and 44% of all patients with high-level lesions). Of these 31 patients, 16(52%) were asymptomatic, 24, (77%) had a thickened fatty filum, 13 (42%) had normal conus position, and 23 (74%) had vertebral anomalies. Twenty-four of the 31 patients (77%) underwent surgical untethering. CONCLUSION: A substantial number of patients with all types of imperforate anus have occult myelodysplasia that may necessitate surgical intervention, including those patients with normal spine radiographs.

The management of the neuropathic bladder in adolescents with imperforate anus.

The management of 58 patients born with an imperforate anus who presented to the urology service and who are currently 18 years old or older is discussed. Of the 44 patients with a high imperforate anus 43 were treated by a rectal pull-through and 1 by an anal cut back procedure, while an anal cut back procedure was used in all 14 children with a low imperforate anus. A total of 32 children (55%) had a neuropathic bladder (hyperreflexic in 29 and atonic in 3). A spinal deformity was present in 72% of the hyperreflexic group but not in the atonic group. Vesicoureteral reflux occurred in 41% of the patients, two-thirds of whom had a neuropathic bladder. A total of 30 children had an associated genital anomaly and 27 had an upper tract anomaly. Nineteen children underwent an operation for the neuropathic bladder, with modern reconstructive methods involving substitution or augmentation cystoplasty, supplemented with self-catheterization, being superior to older methods with regard to continence. The incidence of a neuropathic bladder in these children is high in both operative groups but it is usually associated with a spinal deformity and unlikely to be iatrogenic in nature unless proved to be of lower motor neuron origin. Early operative management is advised to achieve continence and minimize renal impairment.

Genital malformations and coexistent urinary tract or spinal anomalies in patients with imperforate anus.

PURPOSE: Urinary tract malformations have been described in up to 50% of patients with imperforate anus but genital anomalies have been less well analyzed in the same patient population. We sought to evaluate the frequency of coexisting genital, urinary and spinal malformations in a population with imperforate anus. MATERIALS AND METHODS: We reviewed 128 cases of imperforate anus, focusing on genital malformations and their relationship to anomalies of the urinary tract and spine. The series included 69 boys and 59 girls with low (59), intermediate (22) and high (47) imperforate anus. RESULTS: Boys were much more likely to have a genital or upper urinary tract problem than girls (26 or 50 versus 5 or 30%, respectively). The risk for both sets of problems increased with the level of the anorectal lesion. The incidence of genital malformations increased from 14 to 26% in the presence of a renal lesion and from 10 to 23% with an associated spinal problem. Conversely, the incidence of urinary and spinal anomalies increased in patients with genital malformations. CONCLUSIONS: The genitalia of children with imperforate anus should be carefully examined. Patients with anorectal malformations should also be evaluated for urinary tract and spinal problems. The yield of such studies increases in patients with recognized genital malformations.
