The incidence of contralateral PPV on laparoscopy in previous studies was reported as 20%-50%, but it is believed to approach 100% in premature infants. It has been reported that 4%-34% patients have the risk of developing subsequent metachronous contralateral hernia after a repair of an ipsilateral hernia.Iu If this is true, then the identification and closure of a PPV at the time of ipsilateral hernia repair will obviate the need for a second operation in thousands of children every year. With recent advances in minimally invasive surgery, transinguinal diagnostic laparoscopy has emerged as a safe and effective method for evaluating a pediatric patient with PPV. Meanwhile, the laparoscopy has been widely used to manage the infantile hypertrophic pyloric stenosis （IHPS）, due to equally high success rate, minimal complications, and a shorter hospital stay.展开更多
