[Non-palpable testicle: joint review of pediatric endo-surgical group and its management by laparoscopy]. / El testículo no palpable y su tratamiento por laparoscopia. Revisión conjunta del Grupo Español de Endocirugía Pediátrica (GEEP).

We present the joint serie of 5 Pediatric Centers with 256 patients diagnosed of cryptorchidism with nonpalpable testis treated by laparoscopy. We have found that Ultrasound examination is not very useful. This entity affects more to the left side 60%. In near half of the cases 46% we have not found any testicle and in 54% it was carried out an orquidopexy by different methods. In 27% we made an orquidopexy by Fowler-Stephens technique with 86% of good results. We think that laparoscopy is the best way of diagnosis and treatment of this patients.

[Should the medico-surgical strategy for biliary atresia be changed in view of liver transplantation as a reality?]. / Debe cambiar la estrategia medico-quirúrgica de la atresia biliar ante la realidad del trasplante hepático?

Biliary atresia (BA) is the main source of candidates for paediatric liver transplantation (PLTx) with 64 per 100 of survival. The follow-up of 35 immediate candidates of BA, 19 of them transplanted, induced to the authors to change some details on the BA treatment. This disorder does not finish already with portoenterostomy. Eventually mortality causes are infection and chronic rejection. The functional loss of jejunal segment in the Roux en Y may explain the poor cyclosporin absorption and therefore chronic rejection. By other hand, chronic malnutrition presented by these patients before PLTx may favour infection. Authors recommend more aggressive medical treatment before PLTx and technical improvement in the portoenterostomy with the aim of previous surgery does not difficult posterior PLTx.
