Factors influencing inguinal hernia symptoms and preoperative evaluation of symptoms by patients: results of a prospective study including 1647 patients

Background Current recommendations for hernia treatment suggest applying techniques aimed at reducing postoperative pain in patients experiencing intense preoperative pain. However, there is still no reliable stratification method of preoperative pain, its circumstances, intensity and frequency, and the current assessments of hernia symptoms are performed by means of a subjective evaluation. The aim of this work is to discuss preoperative pain before hernia repair and determine its nature depending on the type and length of hernia persistence and the patient’s age.
