Six cases of confirmed retained surgical sponges are reviewed. In five patients a clean, clear-cut acoustic shadow could be identified in relation to a palpable mass. In four of these patients the sponges were identified preoperatively by their ultrasonographic appearance. Abdominal radiographs were usually obtained afterwards, to confirm the diagnostic impression or to rule out bowel gas or calcifications. Since this ultrasonographic finding has not been described previously, the authors call attention to it in order to prevent misdiagnosis.
回顾了6例确诊的手术海绵残留病例。在5例患者中，可在可触及的肿块处发现清晰明确的声影。其中4例患者术前通过超声表现识别出了海绵。之后通常会进行腹部X光检查，以确认诊断印象或排除肠道气体或钙化。由于此前尚未描述过这种超声表现，作者特此提请注意，以防止误诊。
