Liquid-injection for preperitoneal dissection of transabdominal preperitoneal (TAPP) inguial hernia repair

Background The creation of an adequate peritoneal flap during laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair, while avoiding injuring surrounding structures can be technically challenging. Liquid infiltration of the preperitoneal space can help facilitate dissection and avoid inadvertent injuries. We describe a novel technique for TAPP inguinal hernia repair using liquid-injection for preperitonal dissection and report our initial experience.
