Abstract: Laparoscopic inguinal hernia repair (LIHR) is a surgical procedure of preperitoneal repair under laparoscope. It is well suited for young patients due to the advantages of postoperative slighter pain, faster resuming non restrictive activities and better cosmetic effect. Total extraperitoneal and transabdominal preperitoneal (TAPP) are alternative for experienced surgeons and TAPP is recommended for complicated hernias or beginners. Most of the inguinal hernias in young males are congenital indirect hernias, accompanied with varicocele or cryptorchid. Varicocele can be handled simultaneously during LIHR and treatment scheme for cryptorchid should be formulated before LIHR according to different situations. Cryptorchid located in abdominal cavity or inner mouth can be resected in LIHR for resectable cryptorchid. Incaecerated scrotal hernia is common in young males and can be treated by hybridization technique. Femoral hernia should be paid attention in young females. Femoral hernia of most patients can be excised completely under laparoscope if combined with cyst of uterus round ligament. If possible, young females are suggested to preserve round ligament of uterus. Keyhole surgery and T-dissection are available for selected.
