The primary objective of the present study is to investigate a possible correlation between abdominal wall function and subjective measures of QoL before and after laparoscopic repair of small- to medium sized incisional hernia.

This prospective study includes 25 patients undergoing laparoscopic incisional hernia repair. Abdominal wall function is examined by determination of maximal truncal flexion and extension with a fixated pelvis using a Goodstrength dynamometer (Metitur Ltd., Jyväskylä, Finland). Subjective scores of QoL (HerQLes), pain (visual analogue scale) and physical activity (International Physical Activity Questionnaire) are assessed. Patients are examined before, one month after and three months after the operation. Furthermore, pulmonary function is examined preoperative and three months postoperative by standard spirometry (forved vital capacity, peak expiratory flow, forced expiratory volume in 1 second) as well as maximum in- and expiratory pressure is measured.

Inclusion Criteria:

• Elective laparoscopic repair for one or more incisional hernias in the midline (at least 5 cm caudal to the xiphoid process and at least 5 cm cranial to the pubic bone), using a synthetic mesh
• Horizontal fascial defect between 3 and 8 cm
• Age between 25 and 75 years
• American Association of Anesthesiologist score between I and III
• Body mass index < 33 kg/m^2

Exclusion Criteria:

• Severe musculoskeletal, neurologic or cardiopulmonary disease preventing the patient from climbing stairs or shopping for groceries
• Existing stoma
• Postoperative complications requiring intervention

This prospective study includes 25 patients undergoing elective laparoscopic incisional hernia repair. Patients are included from Bispebjerg Hospital and Hvidovre Hospital, two university hospital surgical departments with unrestricted referral of patients.
