A survey of abnormalities in the colon and rectum in patients with haemorrhoids.
BACKGROUND
Haemorrhoids are a common problem in daily practice. However, symptoms may also be caused by other abnormalities in the rectum or colon. Data on the presence of these abnormalities in patients with haemorrhoids is sparse. To examine the prevalence of abnormalities of the colon or rectum in patients with and without haemorrhoids, stratified for age.


METHODS
In a 17-year period 1910 consecutive patients with haemorrhoids and 7936 patients without haemorrhoids were analysed retrospectively. All of these patients had an endoscopic examination for different clinical reasons. All significant endoscopic co-findings (diverticuli, polyps, cancer, angiodysplasia and varices, or colitis) were recorded.


RESULTS
The patients were divided in 2 groups. Group 1 (n = 861 (45.1%)) consisted of patients with only haemorrhoids, group 2 (n = 1049 (54.9%)) consisted of patients with haemorrhoids and another endoscopic diagnosis. Patients in group 1 were significantly younger, mean age 55.3 +/- 14.1 years versus 67.4 +/- 12.1 years (p < 0.001), and underwent significantly more often a sigmoidoscopy, 11% versus 2% (p < 0.0001). Furthermore, endoscopic co-findings were found with increasing age. The majority of diverticuli, polyps, cancer and vascular lesions were detected in the age group above 50 years, while only colitis was more often present in the younger group. There was no significant difference in gender when group 1 and 2 were compared with the reference group. Diverticuli and angiodysplasia/varices occurred significantly more often in group 2. The other significant diagnoses were diagnosed more often in the reference group.


CONCLUSIONS
In patients with haemorrhoids other abnormalities can be present. Especially in older patients the clinician must be cautious to attribute complaints solely to haemorrhoids.
