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 .
Hernia surgery in a defined population: a prospective three year audit.
OBJECTIVE To establish a register of  inguinal hernia surgery  that allows audit and analyses of data from several centres . DESIGN Prospect i ve recording of data on a common protocol . SETTING Eight Swedish hospitals . SUBJECTS All groin hernia operations done for patients over 15 years old from January 1992 to December 1994 . MAIN OUTCOME MEASURES Methods of repair , postoperative complications including mortality , day surgery rate , and reoperations for recurrence . RESULTS During the three years studied 4879 hernia operations were undertaken in 4474 patients .  Postoperative mortality within 30 days of operation for emergency and elective hernia repairs was 3.5 % and 0.07 % , respectively . Of all herniorrhaphies 798 ( 16 % ) were done for recurrences , 142 of these after operations between 1992 and 1994 . At 24 months 4 % of all operations had been redone because of recurrences with highly significant variations among hospitals ranging from 1.5 % to 6.7 % . Postoperative complications within 30 days after operation , direct hernia , recurrent hernia , and the use of absorbable sutures were associated with an increased risk of reoperation . CONCLUSIONS A quality register recorded voluntarily can identify significant interhospital differences in outcome as well as variables associated with an increased risk of reoperation , thereby raising quality awareness and facilitating the process of improvement
