Danish male patients who had undergone bilateral TAPP (July 2012 to June 2013) were recruited from the Danish Hernia Database and cross-checked with hospital files and the National Patient Registry. A standardized postal questionnaire was sent out two years after the index surgery to investigate Patients Related Outcome Measures (PROMs) such as chronic post-operative pain.

The present study was primarily undertaken to provide evidence for the risk of activity-related chronic postoperative inguinal pain following bilateral TAPP in an all-male Danish setting. Impaired sexual activity and sleep disturbance due to pain was also recorded. Data based on nationwide consecutive patients undergoing bilateral TAPP. Data collected for the Danish Inguinal Hernia Database, hospital files and the National Patient Registry (Denmark).
