title: Histopathological study of oesophageal mucosa in patients with varices: a comparison between bleeders and non-bleeders.
abstract: Thirty-six patients with oesophageal varices underwent a non-shunting operation including oesophageal transection. Of these, 16 had an emergency or elective operation (bleeders) and the remaining 20 had prophylactic surgery (non-bleeders). A comparative study was performed between the bleeders and non-bleeders in terms of preoperative endoscopic findings and histopathology of the oesophagus. The severity of red colour sign showed no significant difference between the two groups. The venous dilatation in each of the three layers of the oesophageal mucosa was demonstrated histologically to be of the same degree in bleeders and non-bleeders. In addition, the hepatic venous pressure gradient in cirrhotic patients did not differ between the two groups; for bleeders this was a mean(s.d.) of 15.2(6.1) mmHg and for non-bleeders 14.4(2.9) mmHg. We were unable to find any factors differentiating bleeders from non-bleeders, although these results do not justify prophylactic surgery for oesophageal varices.
