RESUMEN
We report a case of foetal urinary bladder rupture due to posterior urethral valves. A megacystis was diagnosed in a male foetus during routine second trimester ultrasound examination. The diagnosis of bladder rupture was made as, one week later, the bladder became undetectable with the appearance of ascites. During the follow-up, no oligohydramnios developed and intercurrent ascites resolved spontaneously. There are three described mechanisms releasing bladder hyperpressure: bladder diverticles, unilateral vesicoureteral reflux and bladder rupture. In this case, another mechanism might be involved: a patent urachus. The urethral valves were resected and no other surgical treatment was needed. The renal function remained normal. No long-term vesical follow-up of this pathology is available in the literature.

We report the case of a newborn presenting with a pediculated mass arising from the anal margin. Antenatal sonogram and magnetic resonance imaging were unable to diagnose the precise nature of the lesion. Sacrococcygeal teratoma, an enterogenous cyst, a polyp, a prolapse or other perineal tumors were all proposed as possible entities. At birth, no other anatomic anomaly than this homogenous 2 cm para-anal lesion was seen. Excision of the mass was performed under general anesthesia. The postoperative histological exam showed mature fat cells. Reviewing the literature, there have been few previously reported cases of congenital perineal lipoma. It is a rare, benign and easy-to-treat condition that can be evocated by morphological sonography or magnetic resonance imaging (MRI).

Stenosis due to a diaphragm is a type of intrinsic duodenal obstruction in newborns and even in childhood, when obstruction is partial. We present a case of a 13-month-old girl with diaphragmatic stenosis associated with a dilated first and second duodenum. Surgical management consisted of a partial excision of the diaphragm after vertical incision of the anterior part of the second duodenum followed by a transverse suture. This diamond-shaped anastomosis was successfully carried out laparoscopically. No tapering of the duodenum was performed as some authors suggest in cases of megaduodenum. The rapid resumption of peristalsis and fewer adherences than expected after such a minimally invasive approach could make a more invasive procedure unnecessary. Only long-term follow-up and greater experience will show which procedure is most suitable.
