Abstract: Objective To analyze the self-gripping mesh and mesh fixed with tacks in laparoscopic transabdominal preperitoneal (TAPP) herniorrhaphy for giant inguinal hernia.Methods A total of 80 patients of giant inguinal hernia who were subjected to TAPP from Jan.2014 to Jan.2016 were studied. All patients were divided into two groups, including self-gripping mesh group (observation group, n=42) and mesh fixed with tacks group (control group, n=38). The operation time, hospital stay after operation, hospitalization cost, complications and visual analogue scale (VAS) after operation were observed. Results All the operations were successfully completed. There was no significant difference in the average operation time and complications, and comparing with control group, the self-gripping mesh group cost less money and caused less pain, the difference was significant (P<0.05).Conclusion Use of self-gripping mesh will decrease hospitalization cost and post hospital stay, and does not increase the risk of complications such as recurrence and it's an effectivemeasure for reducingpostoperative pain, which is worth to be popularized.
