(b,c) Preoperative US images show increased intestinal wall echogenicity and wall thickening (arrow), complex ascites (asterisk), and free air (arrowheads) between the hepatic surface and the anterior abdominal wall. (d) Preoperative abdominal radiographs obtained 1 h after US show no pneumoperitoneum. (e) Pneumoperitoneum (arrows) appears on abdominal radiographs obtained 35 h after US.
