Presentation transcript:

Incarcerated hernia. A. An incarcerated femoral hernia is demonstrated as a small bowel segment herniated through the femoral canal. B. In an incarcerated incisional hernia, a small-bowel segment (arrow) is demonstrated as herniated through a small orifice in the abdominal wall. Dilated small-bowel loops proximal to the incarceration are also shown in the peritoneal cavity. C. In an umbilical hernia, a herniated small-bowel segment is demonstrated within the fluid space in the hernia sac. The segment was softly strangulated at the hernia orifice (arrow) formed by defect of the fascia, and was easily reduced by manipulation in the case. D. An incarcerated obturator hernia is demonstrated deep in the femoral region. It locates posterior to the pectineus muscle (arrows) and medial to the femoral artery (A) and vein (V).
