Intramural duodenal hematomas have most frequently been reported in children in a traumatic setting. We present two cases of duodenal hematoma that occurred after upper gastrointestinal tract endoscopy with biopsy in children without significant prior medical history. The diagnosis was made by ultrasound, in correlation with the clinical presentation. Because the patients were hemodynamically stable, they were treated conservatively and the regression of the hematoma was followed up with ultrasound until its complete resolution. These cases demonstrate the risks of endoscopy, which are not to be neglected even in children without impaired coagulation, and the manner in which ultrasound can provide the correct diagnosis and follow-up.

Rivera J, Fusaro F, de Magnee C, Clapuyt P, Reding R. Meso-Rex shunt for immediate portal revascularization in pediatric liver transplantation: First report. Pediatr Transplantation 2011. © 2011 John Wiley & Sons A/S. Abstract: We describe the case of a 13-month-old girl transplanted for biliary atresia with PV hypoplasia. She received the left liver lobe of her mother and presented intraoperative portal thrombosis. Because of technical reasons, the opportunity to have conventional PV reconstruction using the donor left PV stump was lost. Immediate conversion to a meso-Rex shunt, using the recipient jugular vein as a bridge between the superior mesenteric vein and the graft Rex recessus, allowed excellent portal revascularization of the transplant. We suggest that synchronous meso-Rex shunt may constitute a valid alternative to truncal PV anastomosis during pediatric LT.

A case of liver transplantation for HCC complicating BA in an eight-month old infant is reported. HCC in BA is extremely rare. Screening of AFP and ultrasonographic examination should be performed regularly in patients with secondary biliary cirrhosis for early detection of HCC.

We report the case of a young girl who had hemihypertrophy and developed Wilms' tumor in both kidneys and clear-cell adenocarcinoma of the uterine cervix with no maternal history of stilbestrol ingestion during pregnancy. Karyotype on the second Wilms' tumor showed monosomy 22. The link between hemihypertrophy and Wilms' tumor is well known, but their association with clear-cell carcinoma of the cervix has not been previously described. (C) 1993 Wiley-Liss, Inc.
