Congenital Pouch Colon with Segmental Dilatation of Ileum: Congenital Pouch Colon Type 6.

Congenital pouch colon (CPC) is classified on the basis of anatomic morphology into five types. Congenital segmental intestinal dilatation associated with anorectal malformation (ARM) is very rare. We are adding two neonates of CPC type 2 associated with segmental dilatation of the ileum to single similar case described in the literature till date. Temporary stomas with excision of either of the pouches should be considered. "Defective mesenchyme formation during organogenesis" due to abnormal mesenchymal precursor cells is hypothesized as the cause for both ARM and different types of CPC.

Vesical calculi formation on the slit valves of a migrated distal end of ventriculoperitoneal shunt.

Various complications of distal end of the ventriculoperitoneal (VP) shunt have been described in the literature. We present, here, an extremely rare and potentially severe complication of vesical calculi formation on the slit valves of distal end of VP shunt which erosively migrated into the urinary bladder. Suprapubic cystolithotomy performed, peritoneal end of the tube found to be eroding and entering into the bladder with two calculi firmly stuck to slit valves in the distal end of the tubing were removed. Shunt was functional, therefore, it was pulled out and repositioned on the superior aspect of the liver; the urinary bladder was repaired. Patient did well postoperatively. This complication was revealed 1.5 years after the shunt was implanted. Although there were symptoms of dysuria and dribbling of urine of short duration, the patient did not show obvious peritoneal signs; suggesting that, penetration of a VP shunt into the urinary bladder can remain asymptomatic for a long period of time, disclosed late and can lead to considerable morbidity. Careful follow-up is important and management should be individualized.

Bilateral multicystic kidneys--an unusual case.

Multicystic dysplasia of the kidneys is a condition whose prognosis is good as it usually presents unilaterally. Bilateral cases are usually fatal in utero. We report a case of bilateral multicystic dysplasia of the kidneys where the lower moiety of the right kidney was spared cystic change. The patient had normal renal function and, following conservative management, remains alive and well 6 months later.
