Real-time ultrasonography can detect the movement of viscera immediately deep to the abdominal wall. This motion of abdominal contents is called viscera slide, and is produced by the force of respiratory motion (spontaneous viscera slide) or by manual ballottement of the abdomen (induced viscera slide). Viscera slide was observed in 18 "normal" subjects (no history of previous abdominal surgery or peritonitis) and in 24 subjects at "risk" for abdominal wall adhesions because of previous abdominal operations or past history of peritonitis. In 14 of the 24 "risk" group subjects, spontaneous and induced viscera slide was restricted to excursions of less than 1 cm (58.3%). Operations were performed on 18 patients, which confirmed the fact that restriction of ultrasonically detected viscera slide identified abdominal wall adhesions in all cases, but no adhesions were found in patients with normal viscera slide. This ultrasonic finding of restricted viscera slide may be useful in the preoperative discovery and localization of abdominal wall adhesions prior to laparoscopy or laparotomy.
实时超声检查能够立即检测到腹壁深层脏器的运动。腹部脏器的这种运动被称为脏器滑动，它是由呼吸运动的力量（自发性脏器滑动）或通过腹部的手推浮动触诊法（诱发性脏器滑动）产生的。在18名“正常”受试者（既往无腹部手术或腹膜炎病史）以及24名因既往腹部手术或既往腹膜炎病史而有腹壁粘连“风险”的受试者中观察到了脏器滑动。在24名“风险”组受试者中的14名（58.3%），自发性和诱发性脏器滑动的幅度限制在小于1厘米。对18名患者进行了手术，这证实了超声检测到的脏器滑动受限在所有病例中都能识别腹壁粘连这一事实，但在脏器滑动正常的患者中未发现粘连。这种脏器滑动受限的超声表现可能有助于在腹腔镜检查或剖腹手术前对腹壁粘连进行术前发现和定位。
