[Esophageal atresia. Personal experience and review of the literature]. / Atresia esofagea: nostra esperienza e revisione della letteratura.

INTRODUCTION: A long gap between the esophageal pouches in esophageal atresia is a relatively rare finding; it adds a significant challenge in the surgical correction and final outcome. MATERIAL AND METHODS: We retrospectively reviewed all cases of long gap esophageal atresia managed at our institution between 2000 and 2006, focusing on antenatal period, delivery weight, maurity, associated malformations, initial management and definitive repair. RESULTS: Sixteen patients with esophageal atresia were observed. Five of them (31%) presented a long gap. Delayed reconstruction was achieved in 4 children at an average age of 63 days (range 40-95 days). Primary repair was possible at birth in one case. All children had a direct anastomosis with one or more Livaditis myotomies in four cases. DISCUSSION: Surgical management of long gap esophageal atresia remains controversial. Most authors believe that elongation of the native esophagus provides a better functional outcome. In particular conditions, when this goal cannot be achieved, esophageal substitution is the last resort. Many techniques have been proposed to obtain esophageal elongation; although all the procedures give acceptable results, none of them has been unanimously accepted by pediatric surgeons. The circular or spiral myotomy is still the most commonly used technique to lengthen the esophagus in the repair of long gap atresias. CONCLUSIONS: In our limited experience circular myotomy (single or double) has proven an effective and reliable technique which allows direct repair of the esophagus even in the presence of initial gaps of 4 vertebral bodies.

Complete epididymal separation presenting as polyorchidism.

We describe an unusual case of a 21-month-old boy with complete separation of the testis and epididymis. Two homogeneous structures were observed in the scrotum of a newborn boy in addition to a third structure. Polyorchidism was suspected, but follow-up sonographic studies showed a decrease in the echogenicity of the left scrotal structure. Surgical exploration revealed the testis and epididymis to be completely separated, with no duplicated testis. Orchidopexy was then performed.

Cystic dysplasia of the rete testis associated to cryptorchidism: a case report.

A case of cystic dysplasia of the rete testis (CDRT) is reported. Nine months after right orchidopexy, a 10-year-old boy presented a palpable mass in the ipsilateral hemi-scrotum. Preoperative ultrasound showed a cystic lesion involving almost the whole testis. Radical orchidectomy was performed and at gross examination a hilar multiloculated cystic lesion was confirmed; microscopic examination showed cystic spaces lined by benign appearing monostratified epithelium with atrophy of the surrounding testicular parenchyma. These findings were consistent with the diagnosis of cystic dysplasia of the rete testis. Immunohistochemical investigation evidenced a pattern similar to that of a normal rete testis. Renal ultrasound and DTPA scintigraphy performed after pathological diagnosis documented the absence of the ipsilateral kidney. CDRT is a rare cause of scrotal swelling in the pediatric patient. When diagnosis is suspected, based on clinical and sonographic findings, conservative surgery may be considered.
