1/12. Two cases of seminal vesicle fistula.

    Two cases of fistulation into the seminal vesicles are described. One related to Crohn's disease and the other following surgery for carcinoma of the rectum. Both cases were diagnosed by CT sinography. This technique is described and is recommended when attempting to demonstrate the internal communications of difficult perineal fistulae when standard techniques of fistulography fail.

2/12. Anal-canal duplication in a 6-year-old child.

    A 6-year-old girl with an anal deformity had been complaining of pruritus around the anus. A small pit at 6 o'clock was diagnosed as an anal duplication. Fistulography showed a 0.5-cm-depth fistula without communication to the rectum. A 1.5-cm diameter presacral mass was shown on computed tomography. There was no sacral anomaly. At fistulectomy, the fistula contained mucous, yellow-white fluid. The base was enlarged, probably because of inflammation, but was resected without any invasion of the rectum. histology showed squamous epithelium on the surface of the fistula and columnar epithelium and goblet cells in the base, which confirmed the diagnosis of an anal-canal duplication.

3/12. oligohydramnios and megacolon in a fetus with vesicorectal fistula and anal-urethral atresia: a case report.

    Severe oligohydramnios and extremely dilated bowel filled with hyperechogenic material floating in fluid were the ultrasonographic findings in a fetus at 27 weeks' gestation. Vesicorectal communication and urethral-anal atresia permitted urine to empty into the colon, causing megacolon, oligohydramnios, and markedly increased intraabdominal pressure resulting in pulmonary hypoplasia.

4/12. Anorectal-vestibular fistula without an imperforate anus in female infants: report of three cases.

    An anorectal-vestibular fistula without an imperforate anus in female infants is a rare clinical condition. This report is based on a series of 3 female infants who had fistulous communication between the bowel and the vestibule coexisting with a normal anus. Redness of the external genitalia over the labia major was the initial symptom in all 3 cases, and a suppurative discharge of pus mixed with stools was also found at the orifice of the fistula. Based on our experience, initial surgery with a double-barrel colostomy followed by a sequential fistulectomy might be safe and curative. We also review the related literature for the pathogenesis.

5/12. Low anorectal malformation associated with 'ano-urethro-cutaneous' fistula.

    Anorectal malformations are one of the common congenital anomalies encountered in the newborn period. The plethora of anomalies described makes it a complex subject for embryological explanations. Fistulous communications between the blind rectum and the urinary tract are common in boys with high/intermediate anomalies, but it is uncommon in children with low anorectal malformations, more so a double fistula. We are reporting a case of 'ano-uerthro-cutaneous fistula' associated with a low ano rectal malformation.

6/12. 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.

7/12. The role of fistulography in fistula-in-ano. Report of five cases.

    A retrospective review of 27 patients undergoing anal fistulography is presented. The etiology of the 27 fistulas studied are as follows: cryptoglandular infection in 18, IBD in 7 (Crohn's 6, CUC 1), iatrogenic in 1, and foreign body perforation in 1. Twenty-six fistulograms revealed either direct communication with the anus or rectum, or abscess cavities/tracts, or both. Two fistulograms revealed no radiographic evidence of fistula (one patient had two fistulograms). In 13 of the 27 patients (48 percent) information obtained from the fistulograms revealed either unexpected pathology (n = 7) or directly altered surgical management (n = 6). We conclude that anal fistulography in properly selected patients may add useful information for the definitive management of fistula-in-ano.

8/12. Hyperchloremic metabolic acidosis as a clue to recto-urethral fistula in an infant with anal atresia.

    An infant with high anal atresia and transverse colostomy, in whom initial radiologic evaluation of the urinary tract had been normal, developed hyperchloremic metabolic acidosis at 24 days of age. gastroenteritis and renal tubular acidosis as possible causes for this metabolic disturbance were excluded, which prompted a repeat investigation of the possibility of a communication between the urinary tract and the rectum. A recto-urethral fistula was demonstrated by urethrography. Analysis of the fluid obtained from the left colon as compared to urine in the bladder and voided urine demonstrated that electrolyte exchange was taking place in the colon, resulting in hyperchloremic hypokalemic acidosis. Treatment with oral sodium bicarbonate and daily lavage of the left colon resulted in normalization of the acid-base status and catch-up growth of the baby. Hyperchloremic acidosis associated with anal atresia and recto-urinary communication appears to be uncommon. However, early diagnosis and treatment of the metabolic derangement are of importance as it may determine the infant's overall prognosis.

9/12. Urethroperineal-rectal fistula in Crohn's disease.

    A 19-year-old white male with Crohn's disease, who complained of passing urine per rectum and having retrograde ejaculations, was noted to have a urethroperineal-rectal fistula. The fistulous communication remained patent despite pharmacologic therapy, a diversion ileostomy, and a total proctocolectomy. A fistulectomy and definitive urethral repair finally resulted in resolution of the problem.

10/12. Rectal ejaculation and prostatic carcinoma.

    A case of carcinoma of the prostate causing fistulous communication between the rectum and the prostatic ducts is presented. The patient's initial symptoms included gradual onset of inability to ejaculate and the complaint of ejaculation per rectum. Appropriate urologic studies demonstrated a fistulous connection between the area of the ejaculatory duct and the rectum. Microscopic studies of rectal discharge confirmed that semen was exiting through his rectum. All genitourinary symptoms in patients with carcinoma of the prostate warrant thorough investigation.
