The purpose of this study is to compare two methods for reinforcement of the abdominal
donor-site after breast reconstruction with the pedicled TRAM-flap. Reinforcement of the
abdominal donor-site is performed, after randomization, with either a porcine derived
biological mesh or a synthetic mesh. The patient and the investigator is blinded.
The aim is to identify the most optimal method for reinforcement of the abdominal donor-site
and thereby contribute to fast and complete rehabilitation of women undergoing breast
reconstruction with the pedicled TRAM-flap after surgical removal of the breast tissue due to
breast cancer, precursors to breast cancer or an increased risk of developing breast cancer
and thereby following preventive removal of the breast tissue.
The patients visit the outpatient clinic 4, 12 and 24 months after operation and abdominal
wall function, the donor site morbidity, the frequency of postoperative complications, the
aesthetic appearance of the reconstructed breast and the abdominal wall and costs are
evaluated.

Primary | Abdominal wall function change | Strength of abdominal wall is assessed by a standardized physical examination developed in collaboration with physiotherapists. A dynamometer is used to get an exact value of muscle strength. | Change from before surgery to 12 and 24 months after surgery | |
Secondary | Abdominal donor site morbidity | Bulge Definition: visible abdominal contour abnormality, without the presence of a fascial defect, with or without the need for surgical correction. Assessed after 3-4, 12 and 24 months by clinical examination and after 12 and 24 months by CT scanning including the Valsalva maneuver Hernia Definition: abdominal wall bulge with the presence of a palpable fascial defect and/or a fascial defect found during an additional correcting surgical procedure or by CT scanning. Assessed after 3-4, 12 and 24 months by clinical examination and after 12 and 24 months by CT scanning including the Valsalva maneuver Abdominal donor site correction procedure (within 24 months) Pain/ discomfort Assessed after 3-4, 12 and 24 months by DoloTestĀ® Study specific questionnaire regarding postoperative assessment of abdominal pain/ discomfort including effect on daily life activities and ability to perform sport |
24 months | |
Secondary | Aesthetics at the abdominal wall | Study specific questionnaire regarding postoperative assessment of the outcome including: Overall satisfaction with the appearance of the abdominal donor site Satisfaction regarding placement and the appearance of the umbilicus Investigators assessment of the abdominal donor site including: Visual bulging of the lower abdomen Placement and appearance of the umbilicus Appearance of the scar |
