Our goal was to validate hand-motion analysis (HMA) as an objective measure of surgical skill on real patients. METHODS HMA (hand movement frequency, hand travel distance) was evaluated serially on 2(More)
We present a case of intraperitoneal bladder rupture in a 42-year-old man repaired by a laparoscopic approach. Details of the case and a description of the operative procedure are outlined. We also review the literature on laparoscopic repair of traumatic bladder rupture.
