We found that female sex , direct inguinal hernias at the primary procedure , operation for a recurrent inguinal hernia , and smoking were significant risk factors for recurrence after inguinal hernia surgery .
Background .
Several factors influence the risk of recurrence after inguinal hernia surgery ; however , a systematic review and meta- analysis of patient-related risk factors for recurrence after inguinal hernia surgery has not been performed earlier .
Inguinal herniorrhaphy in women
Inguinal hernias in women are relatively rare , and an outcome in this specific subgroup of hernias has not been documented in the literature . An analysis was performed using data from the prospect i ve recording of 3,696 female inguinal hernia repairs in the national Danish hernia data base , in the 5.5 year period from January 1 , 1998 to June 30 , 2003 , where observation time specific reoperation rates were used as a proxy for recurrence . In the 3,696 female inguinal herniorrhaphies recorded , the overall reoperation rate was 4.3 % , which is slightly higher compared to male inguinal herniorrhaphies  ( 3.1 % ) ( P=0.001 ) . The reoperation rate was independent of the type of surgical repair . In 41.5 % of the reoperations a femoral hernia was found , compared to 5.4 % in males . Female inguinal herniorrhaphy is followed by a higher reoperation rate than in males , and is unrelated to the type of repair . The frequent finding of a femoral hernia at reoperation suggests the need for the exploration of the femoral canal at the primary operation
