This is a prospective cohort study. Patients have an incisional or parastomal hernia with \>20 cm fascial defect on pre-operative imaging who will undergo an anticipated open bilateral transversus abdominis release with retromuscular synthetic mesh will have their abdominal wall tension measured using a tension scale and their intra-abdominal pressure measured using a urinary catheter containing pressure sensors. The investigators aim to quantify the changes, as well as explore and describe the physiologic shifts that may be associated with these changes.
Study Type
OBSERVATIONAL
Enrollment
2
Abdominal wall tension measurement All patients will have the tension of their abdominal wall measured during surgery using a tension scale or "tensiometer."
Intra-abdominal pressure All patients will have their intra-abdominal pressure continuously monitored using Sentinel's FDA approved TraumaGuard catheter, a pressure-sensing urinary catheter.
