The abdominal standing plain x-ray film showed gas shadows and the gas-fluid levels in the intestine, but there was no free gas under the diaphragm (Figure 1A). This finding was consistent with a small intestinal obstruction or OH (Figures 1B-D). When the incarcerated intestinal wall was returned to its original position, a 3-cm-diameter section of ischemic necrotic tissue was detected (Figures 1E-G). Antibiotic therapy and rehydration were provided after the operation, and no obvious abnormalities were detected by postoperative CT (Figure 1H).
