 Laparoscopic totally extraperitoneal hernioplasty TEP is one of the treatment options for the repair of primary unilateral inguinal hernia. Previous studies showed that patients underwent TEP have less post-operative pain and earlier return to normal activities. However, chronic pain is still a major issue affecting quality of life after TEP with a reported incidence of 9.2-22.5. Mechanical stapling is the most commonly used method of mesh fixation to prevent mesh migration but nerve entrapment by staples causing intractable pain had been reported. Recently several clinical trials showed that mesh fixation with fibrin sealant FS in TEP resulted in less chronic pain but increased incidence of seroma. A spraying device for application of FS laparoscopically is now available which can achieve mesh fixation by using fewer amounts of FS.
