[Ultrasonographic aspect of the rectal wall in liver cirrhosis].

The aim of this study was to assess the ultrasonographic abnormalities of the rectal wall and surrounding structures in patients with cirrhosis and to correlate these findings with endoscopy. From November 1992 to May 1993, 53 cirrhotic patients and 30 control subjects were examined by transrectal ultrasonography and rectoscopy. In addition to rectoscopy and transrectal ultrasonography, patients with cirrhosis underwent an upper gastrointestinal endoscopy.
