Objective To discuss some problems about the procedure choice,the size of mesh and the necessity of mesh stapling in laparoscopic inguinal herniorrhaphy.Methods Laparoscopic inguinal herniorrhaphy was performed in 212 patients with inguinal hernia,including intraperitoneal onlay mesh(IPOM) in 18 cases,transabdominal preperitoneal hernia repair(TAPP) in 20 cases,and totally extraperitoneal hernia repair(TEP) in 174 cases.All patients were followed up for 1 to 50 months.Results Among patients underwent IPOM,The operation time was 38 to 162 min,adhensive intestinal obstruction occurred in 2 patients,bladder injury in 1 case and reoccurrence in 2 cases.Of patients underwent TAPP,the operation time was 52 to 136 min,1 patient had the symptoms of adhensive intestinal obstruction and 1 case appeared inguinal pain,no reoccurrence occurred.AS for patients underwent TEP,the operation time of stapled ones was 36 to 187 min,and 30-62 min of the nonstapled,the complications were mostly hematomas or seromas,accounting for 19 cases,4 cases appeared inguinal pain,1 case suffered bladder injury and only 1 patient recurred.Conclusions Laparoscopic herniorrhaphy is safe and reliable.The key points to assure operation success include thorough understanding of inguinal anatomy,skilled technique and experience summarization.
