Ultrasonic detection of viscera slide as an indicator of abdominal wall adhesions.
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.
