The team evaluated rectal varices to identify any common characteristics of varices that are susceptible to hemorrhage.
The findings of the study were reported in the March issue of Endoscopy.
Of 425 patients with portal hypertension, who had been treated at the authors' institution, 40 individuals with rectal varices were identified.
Patient data regarding underlying hepatic diseases, hepatic function, and endoscopic findings with regard to varices were retrospectively examined.
The investigators found that bleeding from rectal varices occurred in 15 of the 40 patients.
Although the prevalence of hemorrhage tended to increase with exacerbation of hepatic dysfunction, no significant differences were found.
|Increased prevalence of hemorrhage:|
- Rectal varices of advanced form
- Varices with positive ‘red color'
| Endoscopy |
The incidence of hemorrhage tended to be somewhat higher in patients who had undergone any treatment for complicated esophageal varices, than in patients who had not. However, the difference was not significant.
The researchers did find that the prevalence of hemorrhage from rectal varices significantly increased in rectal varices of more advanced form. This prevalence was significantly higher in patients with positive ‘red color' sign.
Dr R. Shudo, of the Kobayashi Hospital, Kitami, Hokkaido, concluded on behalf of the group, "The prevalence of hemorrhage from rectal varices was significantly higher in patients with rectal varices of advanced form and/or with a positive ‘red color' sign."
