[Median raphe cysts of the perineum in childhood].
Median raphe cysts of the perineum are uncommon congenital lesions. Congenital lesions rarely encountered in daily clinical practice. Their diagnosis in childhood is particularly rare. We report two children with these cysts requiring surgical removal. We review the embryological, diagnostic and therapeutic aspects of these cysts, which could be of interest to pediatricians and pediatric surgeons when faced with this pathology in children.

[Participation of the colon in the compensatory process after massive intestinal resection. An experimental study in rats].
The colon participation in the adaptation process after massive intestinal resection (R.I.M.) has been rarely studied. This is an experimental study in rats to know the morphological modifications to the colon after R.I.M. of small bowel. A total of 90 Wistar rats weighing 200-250 grams were used, in two groups. Twenty animals constituted group I (control) and 70 were submitted to resection of 85-90 per 100 of the small bowel (group II, R.I.M.). Radiologic and weights controls has been performed. To end of study (four months),a the animals were sacrificed to obtain histologic samples of the large bowel for structural and morphometric studies. The results of this study to confirm the colon participation in the compensatory adaptation process after R.I.M. of small bowel.

[Acute acalculous cholecystitis secondary to immersion asphyxia. Implications in organ donation].
A case of acute acalculous cholecystitis in a two year-old girl that undergone drowning in sweet water is reported. Cerebral death was diagnosed and the organs donation was authorized. A biliary peritonitis secondary to gallbladder perforation was met during organs extraction. The liver was rejected.

[A technic to avoid postoperative intestinal hypodynamia].
The hypodynamic postoperative ileus in children, has as main cause the circle gastric distension-reflex intestinal ileus, produced by the swallowed air. The gastric emptying system-through a Levin tube from the stomach is not usually sufficient to get off all the swallowed air. Nevertheless, a continuous suction from the lower third of oesophagus, through a double lumen sump tube is twelve times more effective in the getting off de air before it comes into the stomach, without need of a nasogastric tube.
