Urethrorectal fistula ligation and transection in a dog with a history of unilateral abdominal cryptorchidism and misdiagnosed anal gland disease.

A 10-month-old unilaterally cryptorchid male labradoodle dog was presented to a specialty surgery referral center with a reported history of persistent anal sac leakage that was unresponsive to conservative management. The dog underwent castration and left anal sacculectomy but was witnessed urinating from the anus postoperatively. A contrast urethrogram was performed, and a urethrorectal fistula located between the distal portion of the pelvic urethra and the caudal aspect of the rectum was diagnosed. One week later, the dog underwent ligation and transection of the fistula. Surgery was successful and the dog recovered unremarkably with complete resolution of clinical signs. A contrast urethrogram 1 mo after surgery confirmed the successful ligation and transection of the fistula. Key clinical message: To the authors' knowledge, this is the first clinical report of urethrorectal fistula ligation and transection in a dog with unilateral abdominal cryptorchidism and misdiagnosed anal sac disease. Our findings underscore the importance of a thorough physical examination, history taking, and clinical workup for appropriate diagnosis and treatment of multiple congenital abnormalities.

Ligature et transection de la fistule urétrorectale chez un chien ayant des antécédents de cryptorchidie abdominale unilatérale et de maladie des glandes anales mal diagnostiquée. Un chien Labradoodle mâle unilatéralement cryptorchide âgé de 10 mois a été présenté à un centre de référence en chirurgie spécialisée avec des antécédents signalés de fuite persistante du sac anal qui ne répondait pas à une prise en charge conservatrice. Le chien a subi une castration et une sacculectomie anale gauche, mais a été vu en train d'uriner par l'anus après l'opération. Un urétrogramme de contraste a été réalisé et une fistule urétrorectale située entre la partie distale de l'urètre pelvien et la face caudale du rectum a été diagnostiquée. Une semaine plus tard, le chien a subi une ligature et une section de la fistule. La chirurgie a été un succès et le chien s'est rétabli sans particularité avec une résolution complète des signes cliniques. Un urétrogramme de contraste 1 mois après la chirurgie a confirmé la réussite de la ligature et de la section de la fistule.Message clinique clé :À la connaissance des auteurs, il s'agit du premier rapport clinique de ligature et de transection de fistule urétrorectale chez un chien atteint de cryptorchidie abdominale unilatérale et d'une maladie du sac anal mal diagnostiquée. Nos résultats soulignent l'importance d'un examen physique approfondi, d'une anamnèse et d'un bilan clinique pour un diagnostic et un traitement appropriés des anomalies congénitales multiples.(Traduit par Dr Serge Messier).

Congenital aphallia associated with congenital urethrorectal fistula: A rare case report.

RATIONALE: Aphallia is an extremely rare congenital malformation of unknown cause, with few reports in the literature. It is usually associated with other urogenital and gastrointestinal anomalies and is believed to be a result of either the absence of a genital tubercle or chromosome polymorphism. Herein, we describe an extremely rare case of congenital aphallia with congenital urethrorectal fistula and describe our treatment for this patient. PATIENT CONCERNS: An 8-year-old boy was brought to our hospital by his parents because of congenital absence of the penis. The child was male per karyotype and had excess heterochromatin on chromosome 9 (46 XY with 9 qh+). No urethral orifice was identified, and urine passed rectally since birth; thus, urinary tract outlet obstruction led to urine reflux from the anus to the epididymis for a long time. The boy had to be placed on prophylactic antibiotics because he developed urinary tract infection and epididymitis almost every day. DIAGNOSIS: Congenital aphallia (46 XY normal male karyotype) associated with congenital urethroretal fistula. INTERVENTIONS: We performed urethral exteriorization via perineal urethroplasty and urethrorectal fistula repair. The parents approved for phallic reconstruction when the boy reached puberty. OUTCOME: A new external urethral orifice was created on the lower scrotum. The urinary reflux was corrected, and the epididymitis symptoms disappeared. The urethral fistula was then closed. At 8 months follow up, the patient was no longer on antibiotics and had no symptoms of urinary tract infection or epididymitis. CONCLUSIONS: Compatible treatment should be adopted to address urinary tract drainage and infection. Management requires a stepwise approach to address needs as they arise. Neophalloplasty should be performed by an experienced team in early adolescence.

Treatment of Perianal Abscess and Fistula in Infants and Young Children: From Basic Etiology to Clinical Features.

Perianal abscess and anal fistula are 2 common anorectal diseases in infants and young children. However, their causes, clinical diagnosis, and treatment remain controversial. Compared to adults, infants with these 2 diseases exhibit unique clinical characteristics. Blind pursuit of conservative treatment or surgery may worsen the condition, resulting in increased pain in young patients and greater economic burden and psychological harm to parents. Therefore, it is crucial to select correct and effective treatments. This review summarizes the relevant literature from the past 10 years and systematically explains the pathogenesis, clinical characteristics, and treatment measures of perianal abscess and anal fistula in infants with the goal of providing clinicians a deeper understanding of perianal abscess and anal fistula in infants and summarizing safe and effective treatment methods.

Outcome of Single Stage Correction of High Variety of Anorectal Malformation.

The standard treatment of high variety anorectal malformation (ARM) is the staged approach. A growing interest in one stage correction of high variety ARM was noted recently. The aim of this study was to examine the feasibility, safety and outcome of single stage correction of High variety ARM. This prospective study was carried out in the Department of Paediatric Surgery, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2012 to September 2013. It was conducted among 30 patients, all having high ARM. The type of ARM was diagnosed by clinical examinations and imaging studies like Invertogram and Transperineal USG. Other associated congenital anomalies were excluded. Out of 30 patients 11(36.67%) were male and 19(63.33%) were female. The age incidence ranges from 2 days to 5 months with the mean±SD age 1.70±1.63 months. The type of fistula present along with ARM in male varies from rectobulber urethral fistula, recto prostatic urethral fistula, recto vesical fistula and in one case without any fistula. Type of fistula was rectovestibular, rectovaginal and one cloacal malformation among the female patients. The treatment modalities in male patients vary in transabdominal pull through anorectoplasty and PSARP, in which the former was done more (72.73%). In case of female patients, treatment modalities vary in transabdominal pull through and anorectoplasty and transfistulous anorectoplasty, with the later done more (52.63%). Regarding post operative complications, there was 1(14.29%) wound infection in male and 1(33.33%) in female, partial wound disruption in 1(14.29%) male patient, mucosal prolapse 2(28.57%) in male and 1(33.33%) in female, anal stenosis 1(14.29%) in male and 1(33.33%) in female, perianal soiling in 1(14.29%) male patient. All the complications were treated by adopting various measures. One stage correction of High variety ARM in both male and female patients is technically feasible. The safeties of this approach depend on the adherence to strict inclusion criteria. The early post operative complications are acceptable and can be managed successfully.

Congenital anal atresia with rectovestibular fistula, scoliosis, unilateral renal agenesis, and finger defect (VACTERL association) in a patient with partial bicornuate uterus and distal vaginal atresia: A case report.

RATIONALE: Vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect (VACTERL) association and Müllerian duct anomalies are rare conditions. We present a rare condition with the co-occurrence of the VACTERL association and Müllerian duct hypoplasia to characterize patients' clinical presentations, outcomes, and treatment. PATIENT CONCERNS: An 11-year-old girl presented to our hospital with severe lower abdominal pain, lower vaginal atresia with enlargement of the upper vagina and a bicornuate uterus with a Y-shaped uterine cavity filled with hematometra on pelvic magnetic resonance imaging. Her medical history included congenital anal atresia with a rectovestibular fistula, congenital right renal deficiency, congenital right thumb malformation, and scoliosis. DIAGNOSES: 1. Congenital genital tract malformations, a partial bicornuate uterus, and distal vaginal atresia (U3aC0V4); 2. VACTERL association (congenital anal atresia with rectovestibular fistula, scoliosis with hemi vertebra and butterfly vertebra, unilateral renal agenesis, and finger defect). INTERVENTIONS: Colpotomy, laparoscopic exploration, pelvic adhesiolysis, and hysteroscopy were performed. OUTCOMES: Two months after surgery, a pelvic examination showed an unobstructed vagina which was 10 cm long and 2 fingers wide, without adhesion or constriction. LESSONS: Clinicians should have a high index of suspicion when evaluating patients with genital malformations associated with VACTERL. Early diagnosis of distal vaginal atresia with appropriate surgical intervention decreases long-term morbidity.

Functional assessment of the patients with perineal and vestibular fistula treated by anterior sagittal anorectoplasty.

BACKGROUND: Anterior sagittal anorectoplasty (ASARP) has been a standardised operative treatment for anorectal malformation (ARM). This retrospective study was undertaken to evaluate patients with perineal fistula (PF) and vestibular fistula (VF) treated by ASARP in our institution. PATIENTS AND METHODS: Twenty patients (PF, n = 14; male, n = 8 and female, n = 6 and VF, n = 6) were evaluated. Eighteen patients underwent primary ASARP without protective colostomy. Two patients underwent colostomy because of intestinal atresia and suspected of other type ARM. The age range of operation was from 4 months to 5.0 years. Sixteen patients (PF, n = 13; male, n = 7 and female n = 6 and VF, n = 3) over 3 years of age were evaluated according to the Krickenbeck classification. RESULTS: Operative complications occurred in one patient. Minor wound dehiscence occurred in six patients. Mucosal prolapse occurred in two patients. According to the Krickenbeck classification, amongst male patients with PF, all patients had voluntary bowel movements (VBMs) and two patients had Grade 1 soiling, while four patients had Grade 2 constipation. Amongst female patients with PF, all patients had VBM and no soiling, one patient had Grade 1 and two patients had Grade 2 constipation. In patients with VF, one patient was continent with Grade 1 soiling. One patient had Grade 2 and two patients had Grade 3 constipation. CONCLUSIONS: ASARP without colostomy carried a risk of wound dehiscence. The ASARP technique provided normal or moderate outcomes for VBM and soiling. However, in about half of patients, defecation management with laxative therapy was required to achieve a normal condition.

Anovestibular fistula in an infant with retroviral infection - case report.

A vestibular fistula with a normal anus is a rare subtype of anorectal malformation seen more often in East Asia and India. Though mostly congenital, some authors have suggested acquired etiologies for this condition. Infants with retroviral infection have been reported to develop acquired rectovestibular fistulas. We report a case of an infant anovestibular fistula in a patient with retroviral infection.

Laparoscopic dissection and division of distal fistula in boys with rectourethral fistula.

BACKGROUND: Congenital rectourethral fistula (RUF) is the most common form of anorectal malformations found in boys. The aim of this study is to review our experience with dissection and division of distal fistula using laparoscopic surgery in the management of RUF, especially rectourethral bulbar fistula. METHODS: One hundred and two consecutive boys with congenital RUF who underwent conventional or single-incision laparoscopic surgery between July 2008 and June 2015 were enrolled in the study. The dissection of the distal fistula was performed along submucosal layer to a level 0.5 cm proximal to the urethra. Rectal mucosa of the fistula was dissected to the distal most point and completely transected flush with the posterior urethra. The residual muscular cuff was ligated with Hem-o-Lock clip or 5-0 PDS suture. Voiding cystourethrography and pelvic magnetic resonance imaging were performed at 3 mo, 6 mo, and 1 y postoperatively. RESULTS: All patients successfully underwent laparoscopic surgery without conversion. The mean age at the time of operation was 4.3 ± 2.9 mo. The operative times for the rectoprostatic fistula and rectobulbar fistula were similar (118.2 versus 119.4 min, P = 0.082). There was no significant difference in average operative time between conventional laparoscopic surgery group and single-incision laparoscopic surgery group (118.8 versus 119.1 min, P = 0.281). There was no injury to the urethra or vas deferens. The urethral catheter was removed on postoperative day 10. All patients were followed up. The median follow-up period was 3.3 ± 1.8 y. No recurrent fistula or urethral diverticulum was detected on voiding cystourethrography and pelvic MRI at 1 y. CONCLUSIONS: Submucosal dissection and division of distal fistula using a laparoscopic approach is safe, feasible, and effective for congenital RUF, especially bulbar fistula, in boys.

Rare association of congenital penile urethrocutaneous fistula with Y-type urethral duplication.

A 24-year-old man presented with symptoms of difficulty in passage of urine, mixed with gas and stool from penoscrotal junction since birth. He had a history of surgery (posterior sagittal anorectoplasty) for imperforate anus in first week of his life. On physical examination, external meatus was adequate with small 5×5 mm fistulous opening noted at penoscrotal junction with normal anal tone and opening. On evaluation with retrograde urethrography, voiding cystourethrogram, cystoscopy and barium enema, he was found to have penile urethrocutaneous fistula of 0.5×0.5 cm with Y-type incomplete urethral duplication. Urethroanal fistula (Y-type urethral duplication) was of small size (<5 mm), so closed primarily through perineal route with interposition of ischiorectal fat. Penile urethrocutaneous fistula (4 mm) too was closed primarily and covered with tunica vaginalis flap in single sitting. It has been 6 months since surgery and the patient is fully continent and voiding well with no urinary or faecal leak.

Anorectal malformations: definitive surgery during adulthood.

BACKGROUND: Anorectal malformations (ARMs) are rarely seen in adults, since majority of cases are corrected in infancy or childhood. The aim of this study was to describe the profile of patients who underwent definitive surgery to correct their ARM in adulthood, and to discuss the outcomes of surgery (morbidity, mortality, and function). METHODS: This retrospective study included patients 18 years old and above, managed surgically by the Division of Colorectal Surgery at the Philippine General Hospital, University of the Philippines, Manila, from January 1, 2004, to December 31, 2012. Data from the Integrated Surgical Information System and the patients' hospital records were used to fill out a Data Collection Form. Frequencies and percentages were then computed. RESULTS: Eight patients were included in the study. The most common reason for consult was recurrent urinary tract infection (UTI, 25%). One patient had an imperforate anus (IA) without a fistula, and 1 patient had IA with rectal atresia, and the 6 had an IA with a fistula. All but one (87.5%) of the patients had undergone a prior diversion in infancy or childhood. Definitive surgical procedures included posterior sagittal anorectoplasty (PSARP) in 3 patients, anal transposition in 2 patients, laparotomy with colocutaneous anastomosis in two patients, and laparotomy and PSARP in 1 patient. There were 3 cases (37.5%) of postoperative complications. These complications included ureteral injury, enterocutaneous fistula, anal stricture, rectal stricture, rectovesical fistula, and recurrent rectourethral fistula. There was no reported mortality. Five patients already had their stomas reversed at the time of this writing. CONCLUSION: Our results showed that the rarity of the disease, limited surgical experience, and a technically challenging anatomy make the management of ARMs that persist into adulthood a formidable undertaking.

Anorectal malformation with rectobladder neck fistula: A distinct and challenging malformation.

BACKGROUND: Rectobladder neck fistula is the highest and most complex anorectal malformation in boys and the only one that requires an abdominal approach, open or laparoscopic, for repair. The aim of this study was to describe the unique characteristics of rectobladder neck fistulas that warrant special attention and to describe the associated anatomic variants in the genitourinary tract. METHODS: The database of a tertiary medical center was retrospectively reviewed for all patients treated for rectobladder neck fistula, by our team in 1980-2011. Data on surgical history, associated and functional defects, treatment and outcome were collected by chart review. RESULTS: The study group included 111 patients. The most common anatomic urologic defect was a single kidney in 37 patients (33.3%) and the most common functional urologic defect was vesicoureteral reflux in 40 patients (36%), including 11/37 patients with a single kidney (29.7%). Of the 40 patients who underwent cystoscopy, 16 (40%) had a higher than normal location of the verumontanum. Follow-up ranged from 2 to 290months (median 59). Urinary continence was achieved in 40 of the 61 patients (65.5%) for whom data were available, and fecal continence was achieved in 9 of the 69 patients (13%) for whom data were available. A sacral ratio of 0.4 or less was associated with lower rates of urinary control (23%) and fecal control (0%), relative to higher ratios. Twenty stomas (18%) were found to be located too distally, limiting the availability of the bowel for a pull through. CONCLUSIONS: Rectobladder neck fistula carries a poor prognosis for bowel control and is associated with a high rate of urinary malformations that require long-term care. Pediatric surgeons need to be aware of these complications in order to provide proper treatment and parental counseling. Intra-vesical verumontanum is found in a surprisingly high percentage of patients. The combination of a single kidney with vesicoureteral reflux is common and should be closely followed to avoid renal deterioration. Special attention should be given to colostomy construction to avoid complications and unnecessary procedures. A sacral ratio of 0.4 or less is an indicator of poor fecal and urinary control.

Imperforate anus with rectopenile fistula: a case report and systematic review of the literature.

BACKGROUND: Although anorectal malformations (ARMs) are frequently encountered, rare variants difficult to classify have been reported. METHODS: This study describes a patient with ARM and rectopenile fistula. The literature was reviewed systematically to assess the anatomical characteristics, clinical presentations and operations of this rare type of ARM. RESULTS: Eight patients were reported in the six included articles. In three patients, the fistula extended from the rectum to the anterior urethra without communication with the skin. In one patient, the fistula, located deep in corpus spongiosum, opened to the ventral aspect of the penis without communication with the urethra. In the remaining four patients, the fistula extended from the rectum to the cutaneous orifice in the ventral aspect of penis, with communication or a short common channel with the urethra. CONCLUSIONS: Imperforate anus with fistula extending into the penis is a rare variant of anorectal malformation. Unawareness of this lesion resulted in a delay of correct diagnosis and appropriate management. A thorough examination, including colonourethrography and fistulography, should be performed in all patients with a fistula opening in the ventral aspect of the penis.

[An Adult Case of Transperineal Repair of Congenital Rectourethral Fistula Using Gracilis Muscle Flap Interposition].

A man in his 50s was referred to our hospital after recurrent severe urinary tract infection. He had undergone anoplasty for anorectal malformation during early infancy. He noticed urinary leakage from the anus for a long time. Under diagnosis of congenital rectourethral fistula, we performed fistula closure. The fistula was transsected via transperineal incision and each stump was closed. A gracilis muscle flap approximately 30 cm long was harvested from the left thigh, brought into the deepest part between the separated rectum and urethra through a subcutaneous tunnel and fixed there. The urinary leakage from the anus disappeared, and the infection resolved. Application of gracilis muscle flap for congenital diseases is rare, but was useful in the present case.

The management of anorectal malformation with congenital vestibular fistula: a single-stage modified anterior sagittal anorectoplasty.

PURPOSE: This study aimed to evaluate the mid-term outcomes of single-stage modified anterior sagittal anorectoplasty (ASARP) for anorectal malformation with vestibular fistula. METHOD: Twenty-six patients with congenital imperforate anus and vestibular fistula underwent single-stage modified sphincter-saving ASARP between January 2008 and December 2012. The ages of the patients at the time of operation ranged from 1 month to 5.1 years. Standard ASARP procedure was modified to avoid the incision of the external sphincter complex. Instead a potential tunnel was created through the center of external sphincter complex under the endoscopic guidance. The patients were evaluated for fecal continence and complications. RESULT: Modified ASARP was successfully performed in all patients. The mean operation time was 52.2 ± 3.5 min (range 47-61 min). The operative blood loss was minimal. There was no operative complication. Wound infection occurred in 3 patients (3/26, 11.5%). All patients were followed up for 4.2 ± 1.5 years (range 2-6 years). No patient developed fecal incontinence. Three patients (3/26, 11.5%) had soiling once or twice per week. Four patients (4/26, 15.4%) had constipation amenable to diet management. Mucosal prolapse occurred in 1 patient (1/26, 3.8%). There was no recurrence of fistula, anal stenosis or anterior displacement of the neorectum. CONCLUSION: Mid-term results show that single-stage modified ASARP is an effective and safe option for patients with anorectal malformation and congenital vestibular fistula.

Infantile Fistula-in-Ano: A Report of Two Patients and Review for Dermatologists.

Infantile fistula-in-ano is a well-known entity to pediatric surgeons but less recognized by dermatologists. Because these patients may initially present to a dermatologist or pediatric dermatologist, familiarity with the presentation is important. We present two infants with fistula-in-ano and review the literature on this condition.

One stage operation through modified posterior sagittal approach preserving the sphincter intact for anal agenesis with rectovestibular fistula.

PURPOSE: To describe the surgical technique and outcomes of an one stage operation through modified posterior sagittal approach (PSAP) preserving the sphincter intact for anal agenesia with rectovestibula fistula. PATIENTS AND METHODS: 57 patients suffering from anal agenesis with rectovestibular fistula were operated by a one-stage operation through a modified PSAP preserving the external sphincter intact from 2002 to 2010. The operation was performed in one-stage through a posterior sagittal approach with three modifications: The external sphincter complex was not opened on the posterior side, the dissection was carried out outside the rectal pouch, the rectal pouch was not tapered and was pulled through the center of the external sphincter identified by muscle stimulator. RESULTS: Patients age varied from 3 days to 30 days (mean: 21±9 days). The mean operative time was 57±8 min (range, 35-90 min). There were no intraoperative complications. There were no intraoperative or postoperative deaths. There were no early postoperative complications. Follow up from 40 months to 140 was obtained in 52 (91.2%) patients. Constipation has seen in 3 patient, 46 patients (88.5%) had 1-2 defecations per day, 2 patients (3.85%) had 3-4 defecations per day, 1 patients (1.9%) had more than 4 defecations, and 3 patients(5.8%) had one defecation every 2-3 days. Rectal mucosal prolapse occurred in 7 patients who required a second operation. CONCLUSION: One stage operation through modified PSAP is feasible, is safe and provides good continence outcomes for anal agenesis with rectovestibular fistula.

Bowel functional outcomes in females with perineal or vestibular fistula treated with anterior sagittal anorectoplasty: controlled results into adulthood.

BACKGROUND: Anterior sagittal anorectoplasty is a standardized operative treatment for females with congenital rectoperineal or vestibular fistula. The controlled, long-term outcomes require characterization. OBJECTIVE: The aim of this study was to define the bowel functional outcomes following anterior sagittal anorectoplasty in relation to age- and sex-matched controls. DESIGN: This cross-sectional study was conducted at a single institution. PATIENTS: All females treated for congenital perineal or vestibular fistula with anterior sagittal anorectoplasty between 1983 and 2006 were invited to answer a detailed, previously validated questionnaire on bowel function. Each patient was matched to 3 controls who had answered identical questionnaires. Ethical approval was obtained. Social continence was defined as soiling or fecal accidents <1/week and no requirement for changes of underwear or protective aids. SETTING: This study was conducted at the Hospital for Children and Adolescents, University of Helsinki, Finland. INTERVENTIONS: No interventions were performed. MAIN OUTCOME MEASURES: The primary outcomes measured were the prevalence of problems with rectal sensation, voluntary bowel control, soiling, fecal accidents, constipation, and social problems. Bowel function score (out of 20 items) was considered, as well as the age at completion of toilet training for stool. RESULTS: Of 34 respondents (79%; median age, 13 (4-28) years), all had voluntary bowel movements. Problems withholding defecation, soiling, and fecal accidents were significantly more common among patients than controls (p ≤ 0.001). Eighty-five percent of patients and 100% of controls (p = 0.001) were socially continent; 41% of patients and 76% of controls were totally continent (p = 0.0003). Constipation tended to decline with age (from 59% to 25%; p = 0.16). The bowel functional outcome was good in 68% of patients, satisfactory in 26% of patients, and poor in 6% of patients. Diapers for stool had been discontinued at the same median age as controls. LIMITATIONS: Number of patients in comparative analysis of symptoms by age group. CONCLUSIONS: After anterior sagittal anorectoplasty for perineal or vestibular fistula, 2 of 3 of patients are likely to achieve bowel control comparable to normal in the long term, and the vast majority will be socially continent. The effective treatment of constipation is essential.

[Exstrophy of rectal duplication associated with anorectal malformation and penoscrotal transposition with perineal hypospadias. A case report]. / Duplicación rectal extrofiada asociada a malformación anorrectal y transposición pene-escrotal con hipospadias perineal. reporte de un caso clínico.

We present the case of a male patient who required treaatment due to anorectal agenesis with recto urethral fistula and penoscrotal transposition with perineal hypospadias, associated with a perineal tumor. The perineal tumor was found strongly adhered and contiguous to the rectum which makes it compatible with an exstrophy of rectal duplication. Surgical reconstruction of the birth defect was performed in stages until acceptable biological function and esthetic results were obtained.

Long term outcomes of laparoscopic-assisted anorectoplasty: a comparison study with posterior sagittal anorectoplasty.

PURPOSE: The aim of this study is to compare the long term outcomes between laparoscopic-assisted anorectoplasty (LAARP) and posterior sagittal anorectoplasty (PSARP) for children with rectobladderneck and rectoprostatic fistula anorectal malformations (ARM). METHODS: Thirty-two ARM children with rectobladderneck and rectoprostatic fistula who underwent LAARP between October 2001 and March 2012 were reviewed. The outcomes were compared with those of 34 ARM children who underwent PSARP between August 1992 and September 2001. The sacral ratio (SR), age at operation, operative time, postoperative hospital stay and complications were evaluated. Bowel functions were assessed using the Krickenbeck classification. RESULTS: The mean operative time of the LAARP was significantly shorter than that of PSARP group (1.62 ± 0.40 vs 2.13 ± 0.30 h). The postoperative hospital stay was significantly shorter in the LAARP group (5.8 ± 0.65 vs 8.4 ± 0.67 h). The wound infections (11.8% vs 0%) and recurrent fistula (11.8% vs 0%) were more common in PSARP patients. Th e overall morbidity rate of PSARP group was significantly higher than that of the LAARP group (35.3% vs 12.5%, p<0.05). However, 7.5% of the LAARP patients developed rectal prolapse. Twenty-four of 32 patients were followed up for more than 3 years in LAARP group. The median follow up period was 7.5 years (range 4-11) in LAARP patients and 15.5 years (range 11-20) in PSARP patients. The rates of voluntary bowel movement, soiling (grade 1, 2 & 3) were similar in both groups. More patients from PSARP group developed grade 2 or 3 constipation (22.5% vs 0%, P<0.01). CONCLUSIONS: Compared to PSARP, LAARP is a less invasive procedure. The long term functional outcomes after LAARP were equivalent if not better than those of PSARP.
