Experimental reconstruction of an abdominal wall defect with electrospun polycaprolactone-ureidopyrimidinone mesh conserves compliance yet may have insufficient strength.

Summary of "Experimental reconstruction of an abdominal wall defect with electrospun polycaprolactone-ureidopyrimidinone mesh conserves compliance yet may have insufficient strength."

Electrospun meshes mimic the extracellular matrix, which may improve their integration. We aimed to compare polycaprolactone (PCL) modified with ureidopyrimidinone (UPy) electrospun meshes with ultra-lightweight polypropylene (PP; Restorelle) reference textile meshes for in vivo compliance. We chose UPy-PCL because we have shown it does not compromise biomechanical properties of native tissue, and because it potentially can be bioactivated.

Medical and Biotech [MESH] Definitions

A birth defect in which the URINARY BLADDER is malformed and exposed, inside out, and protruded through the ABDOMINAL WALL. It is caused by closure defects involving the top front surface of the bladder, as well as the lower abdominal wall; SKIN; MUSCLES; and the pubic bone.

Rare congenital deformity syndrome characterized by a combination of five anomalies as a result of neural tube defect. The five anomalies are a midline supraumbilical abdominal wall defect (e.g., OMPHALOCELE), a lower STERNUM defect, a congenital intracardiac defect, an anterior DIAPHRAGM defect, and a diaphragmatic PERICARDIUM defect (e.g., PERICARDIAL EFFUSION). Variants with incomplete and variable combinations of the defects are known. ECTOPIA CORDIS; CLEFT LIP; and CLEFT PALATE are often associated with the syndrome.

A protrusion of abdominal structures through the retaining ABDOMINAL WALL. It involves two parts: an opening in the abdominal wall, and a hernia sac consisting of PERITONEUM and abdominal contents. Abdominal hernias include groin hernia (HERNIA, FEMORAL; HERNIA, INGUINAL) and VENTRAL HERNIA.

The outer margins of the ABDOMEN, extending from the osteocartilaginous thoracic cage to the PELVIS. Though its major part is muscular, the abdominal wall consists of at least seven layers: the SKIN, subcutaneous fat, deep FASCIA; ABDOMINAL MUSCLES, transversalis fascia, extraperitoneal fat, and the parietal PERITONEUM.

Surgical removal of excess abdominal skin and fat and tightening of the ABDOMINAL WALL. Abdominoplasty may include LIPECTOMY of INTRA-ABDOMINAL FAT, tightening of the ABDOMINAL MUSCLES, and re-creation of the UMBILICUS.
