Abstract: Laparoscopic inguinal hernioplasty is based on myopectineal orifice and mesh repair. However, the inguinal region is located in the transition area of the trunk and lower limbs, the anatomy is complex. In order to improve teaching and learning, the authors propose to simplify the surgical anatomy of laparoscopic inguinal region, in which myopectineal orifice is simplified to five triangle and a Chinese character as “大”. This is beneficial to master local anatomy and laparoscopic inguinal hernioplasty.
