Case 44 Abdominal Wall Defect



Marten N. Basta and Karl H. Breuing

Case 44 Abdominal Wall Defect

Case 44 A 75-year-old female enters with complaints of abdominal discomfort from worsening ventral abdominal hernia. She had originally undergone an open cholecystectomy, which was complicated by small bowel obstruction requiring emergent exploratory laparotomy and eventual skin graft.



44.1 Description




  • Large ventral abdominal hernia: Full-thickness defect traversing all tissue layers of abdominal myofascial wall




    • Herniation of peritoneal contents with skin directly over bowel



  • Loss of domain: >50% of abdominal contents lie outside of the abdominal cavity




    • Rectus abdominus muscles migrate laterally as a consequence



  • There is no evidence of visceral incarceration



44.2 Work-Up



44.2.1 History




  • Etiology of defect: Congenital, previous surgery, trauma, and resection



  • History of hernia repair: Description of attempts, techniques used, presence of mesh, location, type, and concurrent intra abdominal procedures



  • Duration defect has been present



  • Associated symptoms: Chronic pain, bowel obstruction, physical mobility, and psychosocial impact



  • Nutritional status



  • History of smoking or pulmonary disease



  • Steroids or immunosuppressive medications and autoimmune disease



44.2.2 Physical Examination




  • Body mass index (BMI): Weight (kg)/[Height (m)]2



  • Abdominal wall defect description




    • Location




      • Midline or lateral



      • Upper, middle, or lower abdomen



    • Tissue defect




      • Skin and subcutaneous tissue



      • Myofascial



      • Full thickness



    • Size of defect



    • Condition of existing tissues



  • Pre-existing incisions



  • Evidence of loss of domain



44.2.3 Pertinent Imaging or Diagnostic Studies




  • Computed tomography (CT) of the abdomen with contrast may be helpful to delineate the extent of the defect, the related anatomy, and other relevant information (e.g., bowel adhesions, abscesses)



  • Pulmonary function testing should be performed if there is pre-existing respiratory compromise or suspicion for loss of domain from a large hernia
