Outcome Measures
Primary Outcome Measures
- Proportion of patients with chronic pain that impairs daily function [6 month]
At the 6 month follow up, all participants will be asked to fill out questionnaires regarding pain. Questionnaire used will assess degree of pain and degree of impairment on daily function.
- Proportion of patients with pain related impairment of sexual function [6 month + 12 month]
At 6 and 12 month followup participants will be asked to fill out a questionnaire assessing pain related impairment of sexual function.
- Proportion of patients with pain that impairs daily function [12 month]
At the 12 month follow up, all pariticipants will be asked to fill out qestionnares regarding pain. Questionnaire used will assess degree of pain and degree of impairment of daily function.
- Early postoperative pain [10 days]
During the first 10 days, level of pain will be assessed using a Visual Analog Scale.
Other Outcome Measures
- 30 day complications [30 days]
Complications, occuring within the first 30 postoperative days will be recorded by telephone interview on day 30.
- Cut to suture time [Peroperative]
The cut to suture time will be recorded by the staff in the operating room.
- Lenght of hospital stay [Days]
- Time to return to normal daily activities [Days or weeks]
- Patients comfort [6 and 12 month]
Patients comfort with the operated hernia be assessed using questionnaires.
