Abstract:

Objective　To explore the anatomical nature of the preperitoneal space during laparoscopic inguinal hernia repair, and provide us with anatomical basis for surgery.　Methods　Anatomic observation and analysis were carried out retrospectively on 30 patients undergoing laparoscopic inguinal hernia repair from January 2012 to December 2012 in our hospital．The surgical approaches, anatomic planes and technical tips were also elucidated by drawings and videos.　Results　Retzius space and Bogros space made up preperitoneal space. Transversalis fascia could be divided into superficial layer and deep layer. Between peritoneum and deep layer of transversalis fascia was avascular area. transversalis fascia thickened to form theiliopubic tract, which lied on the posterior aspect of the inguinal ligament. The iliopubic tract formed medial wall of femoral and inferior walls of the inguinal canal. The femoral branches of the genitofemoral nerve and the lateral femoral cutaneous nerve  trvelled through below the iliopubic tract.　Conclusions　The premise of laparoscopic inguinal hernia repair is that we are familiar with the mark point of Myopectineal orifice in preperitoneal space, it has important clinical significance.
