Pseudoexstrophy associated with congenital pouch colon

Congenital pouch colon in Duhok, outcome and complications: Case series

Background

Congenital pouch colon (CPC) is a rare congenital abnormality associated with anorectal malformations with high incidence of complications and mortality. The aim of this study is to describe the various types of congenital colon pouch, their management aspects, complications of surgery, and the best management options.

Results

The incidence of congenital pouch colon in the present study was 5.3% (18 patients) of all anorectal malformations. Sixteen cases (88.8%) were males and 2 cases (12.5%) were females, (M: F ratio was 8:1). The age of presentation was ranged from 1day to 1year; 17 cases were presented in first week of life. Preoperative diagnosis of congenital pouch colon was done in 7 patients. As an initial procedure tabularization of the pouch with end colostomy was done in 15 cases, window colostomy was done in 2 cases, and excision of the pouch and proximal ileostomy was done in one patient. As a definitive procedure, abdomino-perineal pull-through of the tabularized pouch was done in 15 cases, ileo-anal anastomosis after pouch excision was done in 3 cases.

Conclusions

Pouch tabularization and end colostomy had better outcome than other types of interventions. Abdomino-perineal pull through of the tabularized pouch was the definitive surgical procedure for treatment of complete pouch colon in our study.

•

Congenital pouch colon is a rare disease that requires early diagnosis and treatment.

•

Window colostomy at the pouch is better to be avoided due to high incidence of complications.

•

Pouch tabularization and end colostomy has better outcome than other types of interventions.

Early Diagnosis of Bladder Exstrophy: Quantitative Assessment of a Low-Inserted Umbilical Cord

OBJECTIVES

Bladder exstrophy is a rare severe congenital malformation. Early prenatal diagnosis is scarcely described in the literature. Low insertion of the umbilical cord is a constant anatomic feature of bladder exstrophy. The aim of our study was to assess whether early measurements of the umbilical cord insertion-to-genital tubercle length may serve as quantitative measurements for a low-inserted umbilical cord in cases of bladder exstrophy.

METHODS

The umbilical cord insertion-to-genital tubercle length was prospectively measured in all cases referred for a nonvisualized urinary bladder before 18 weeks' gestation. Final diagnoses were compared with prenatal measurements.

RESULTS

Fifteen fetuses were evaluated for a nonvisualized bladder at a mean gestational age of 15.7 weeks (range, 14-17 weeks). Of them, 6 cases were diagnosed with bladder exstrophy, and 9 cases had a normal urinary bladder. All cases with bladder exstrophy had an umbilical cord insertion-to-genital tubercle length below the fifth percentile for gestational age, whereas cases with a normal bladder had a normal measurement.

CONCLUSIONS

Fetuses with bladder exstrophy have an umbilical cord insertion-to-genital tubercle length below the fifth percentile of the general population. This measurement may serve as a complementary objective sonographic parameter in the prenatal assessment and counseling of cases suspected of having bladder exstrophy during early pregnancy.

Antero-posterior Duplicate Exstrophy with a Wet Bladder Plate: A Diagnostic Dilemma

Variants of exstrophy are rare anomalies seen in the spectrum of bladder exstrophy-epispadias complex. We present a rare case of duplicate exstrophy with a wet bladder plate. This is a deviation from the classical description of antero-posterior duplicate exstrophy that is associated with a dry bladder plate.

Congenital pouch colon with duplicate bladder exstrophy

Congenital pouch colon, an unusual high anorectal malformation, is rarely associated with exstrophy variants. We describe a case of congenital pouch colon associated with duplicate bladder exstrophy, never reported before in literature. The relevant literature is reviewed, and the possible embryogenesis of this complex anomaly is suggested.

Pseudoexstrophy with Epispadias

The exstrophy variants are uncommon anomalies. The variants of the exstrophy complex have all the stigmata of the classical exstrophy such as divergent recti, widened symphysis pubis, and low-set umbilicus; however, the urinary tract is intact to a varying degree. Pseudoexstrophy, an exstrophy variant, is very rarely associated with epispadias. We report an unusual case of pseudoexstrophy with epispadias, in whom the intact bladder was initially covered by a mucous membrane which later epithelialized. The epispadias was repaired using a penile disassembly technique with posterior and ventral placement of bladder neck and urethra. Although the urethral meatus was hypospadiac, the child had achieved dry intervals with occasional stress incontinence.

VARIANTS OF THE EXSTROPHY COMPLEX: A SINGLE INSTITUTION EXPERIENCE

PURPOSE

Variants of the bladder/cloacal exstrophy complex are rare. Different presentations and subsequent management and outcome are discussed.

MATERIALS AND METHODS

We performed a retrospective review of our database of more than 815 patients with the exstrophy complex. Patients with variants of classic epispadias or bladder or cloacal exstrophy were identified. Anatomical presentation, surgical management, type of continence procedures and final outcome were evaluated.

RESULTS

Of the 25 patients with variants 13 were treated primarily at our institution and 12 were referred. Time until primary bladder closure ranged from 1 day to 4 years. Followup after continence procedure ranged from 1 month to 39 years. Seven of the 25 patients are awaiting a continence procedure. Six patients are dry without a continence procedure, of whom 4 have superior vesical fistulas. A total of 11 patients underwent bladder neck reconstruction (BNR), of whom 3 are dry, 2 are dry during the day but are wet at night, 1 had a failed procedure and 5 are dry after continent diversion (CD). One additional patient underwent CD initially and is dry. Referred cases of epispadias with bladder prolapse were not recognized at birth and had delayed closure. Impaired bladder growth or failed BNR required CD in 4 patients, and 2 are awaiting a continence procedure. Skin covered and duplicate exstrophy had comparable outcomes to the classic presentations. Duplicated organs were used for reconstructive procedures. Of the 6 patients with cloacal variant 2 are continent of stool and 2 await a Pena procedure. One of these patients has an ileal stoma and 1 has a colostomy.

CONCLUSIONS

The initial presentation of exstrophy variants can be confusing, often delaying initial treatment. Superior vesical fistulas permit continence without BNR due to an intact urinary sphincter. Variants such as epispadias with bladder prolapse and duplicate or skin covered exstrophy should be closed at birth with standardized techniques to promote bladder growth for later BNR. These cases are faced with the same long-term problems as the classic presentation. Cloacal variants can present with intact anal innervation, allowing a later Pena procedure.

Congenital pouch colon associated with anorectal agenesis

This article presents a review of the history and development of the various types of congenital pouch colon. Also described are the criteria for diagnosis, the treatment modalities and the results of follow-up studies to emphasize the post-operative problems. The problem of pre-operative and post-operative fecal incontinence is dealt with in more detail.

Benign symmetric lipomatosis with myelomeningocele in an adolescent: An uncommon association-case report

The authors report an unusual localization of symmetric adipose tumors associated with spinal dysraphism. Initially, the patient underwent a closure of the lumbosacral myelomeningocele. At that time, the tumors were not evident and remained undiscovered up until puberty. However, during puberty, the symmetric lipomatous masses grew at the perineal region. Except the patient's age, all findings and the clinical picture supported the diagnosis of a benign symmetric lipomatosis (BSL). To the authors' knowledge, the following case has not been described previously.

Pseudoexstrophy in a female child

A six-year-old female patient presenting with a swelling in the infraumbilical part of the abdomen, bulging out on straining, was diagnosed to have pseudoexstrophy bladder. The urinary tract was normal. The patient had bifid clitoris. There was no other associated malformation. Surgical repair of abdominal wall defect was done successfully. A new classification of exstrophy variants is proposed.
