Regardless of whether or not the laparoscopic approach is used, the simple closure using an omental patch is considered to be preferable to other surgical therapies for a duodenal ulcer perforation. We used abdominal ultrasonography (US) to identify the perforation site of the duodenal ulcer. To our knowledge, this is the first report describing how the perforation site of duodenal ulcers can be identified using US. Three patients diagnosed with perforated duodenal ulcers based on abdominal computed tomography and abdominal radiographic findings were scheduled for surgery. Under general anesthesia, US demonstrated free air on the liver and a "fish-eye sign" when the anterior or lateral wall was perforated. We performed a simple closure using an omental patch through a skin incision measuring only 3 cm in diameter above the area showing the fish-eye sign. The postoperative recovery was no different from that seen when a laparoscopic approach is used at our hospital. Even though the laparoscopic procedure is still the surgical modality of choice, the US technique allows for a successful diagnosis without invasive examinations. We believe that most surgeons and/or radiologists should try to detect the fish-eye sign using US as the diagnostic modality of first choice if they suspect a duodenal ulcer perforation. This technique allows us to mark the perforation site accurately before surgery.
