Primary reconstruction of fingernail injuries in children with split-thickness nail bed grafts.

INTRODUCTION: Failure to detect and treat partial or complete avulsions of the nail bed may lead to severe nail deformity that predisposes to repeat injuries and is cosmetically inacceptable. Treatment of these injuries with split-thickness nail bed grafts (STNBGs) is controversial and no pediatric series has been published. METHODS: A retrospective, single center case series of nine fingers with complex nail bed injuries that were reconstructed primarily with STNBGs was performed. Surgical outcome and patient satisfaction were assessed. RESULTS: For six nail bed reconstructions, the nail bed graft was harvested from the injured finger, and for the remaining three from the great toe. Harvesting of the great toe's nail bed could be performed without removal of the nail plate by only lifting it up distally. Insufficient vascularization required primary flap coverage in six cases with three Moberg flaps, two palmar V-Y flaps, and one thenar flap. No flap was lost and all nail bed grafts had a 100% take. Only one patient required reoperation due to a hook- and split-nail deformity. All other patients were satisfied or very satisfied and the surgical outcome was least satisfactory in all but two patients. CONCLUSIONS: Primary reconstruction of complex nail bed injuries with STNBGs usually gives good cosmetic and functional results in children and prevents secondary nail growth disturbances reliably.

A minimal invasive surgical approach for children of all ages with ureteropelvic junction obstruction.

OBJECTIVE: Open dismembered pyeloplasty is considered the gold standard to treat ureteropelvic junction obstruction (UPJO) in children. Laparoscopic pyeloplasty (LP) and robot-assisted pyeloplasty (RAP) are increasingly popular. Our present protocol consists of using minimally invasive techniques for all children with UPJO. Here, we report our first 40 cases operated under this protocol. PATIENTS AND METHODS: Retrospective chart review of patients who underwent LP and RAP for UPJO between 2006 and 2010 was performed. Children younger than 4 years of age underwent LP and children aged 4 years and older with robot assistance. Results were assessed comparing pre- and postoperative imaging studies, operating time, hospital course and complications. RESULTS: Thirty-nine patients underwent 41 dismembered pyeloplasties (20 patients LP, 19 patients RAP). No conversions to open surgery were performed. The difference in operative time was statistically significant. The average hospital stay was 7 days (LP) and 6 days (RAP). All patients showed significant decrease of hydronephrosis and the overall success rate was 100%. The complication rate was 25% in the LP and 28% in the RAP group. CONCLUSION: Our data show that RAP and LP are effective to correct UPJO with similar outcomes and complication rates. None of the patients in this series required re-intervention to correct obstruction and the results are comparable with open surgery.
