Purpose: Chronic postsurgical pain （CPSP） is a majorissue associated with surgery. The primary aim of thisstudy was to define the incidence of CPSP after inguinalhernia surgery. The secondary goals were to define riskfactors for the development of CPSP. Methods: We performeda retrospective study analyzing inguinal herniapatients after surgery. We investigated the presence orabsence of pain, the site of pain, and its intensity. Factorssuch as sex, age, time of surgery, days of hospitalstay and the presence or absence of acute postsurgicalpain on the first postoperative day were compared betweenpatients with and without CPSP. Results: CPSPoccurred in 15 out of 49 patients. The median numericalrating scale（ NRS）（ 0-10）, pain score for CPSP was3 （1-8）. CPSP was significantly less in older patients.NRS score for the acute postsurgical pain of patientswith CPSP was 3 （0-10）, but NRS score of patientswho did not produce CPSP was 1 （0-7）. Conclusions:These results indicated that CPSP develops followingapproximately 30% of inguinal hernia surgery cases. Itmay be predicted by the intensity of acute postsurgicalpain on the first postoperative day.
