Chronic postoperative inguinal pain (CPIP) is a diagnostic and therapeutic challenge following inguinal hernia repair. For many years ZweiChirurgen are treating patients from all over Switzerland with this condition. Sometimes it is more convenient for the patients to get their surgery for CPIP close to their place of residence. This week PD Dr. Henry Hoffmann operated a patient with CPIP in the Cantonal Hospital Aarau with the referring colleague Dr. Alexander Gräfitsch, senior physician surgery.
