One stop rectal bleeding clinic: the coventry experience.

Among most patients attending a rectal clinic, rectal bleeding is a common presenting feature. In most patients, the cause is attributed to a benign lesion. In a small percentage, the cause is neoplastic, and for this reason, rectal bleeding merits further study. Left-sided tumors account for the majority of these tumors and are within the reach of a flexible sigmoidoscopy. This study aimed at examining the diagnostic performance of the one stop rectal clinic in Coventry. Between November 2001 and May 2002, 250 consecutive patients were seen in the one stop rectal bleeding clinic of a tertiary referral hospital. Patients were asked of the nature of rectal bleed and altered bowel habits and were examined by digital rectal examination, with a proctoscopy and rigid sigmoidoscopy before either a full colonoscopic examination or flexible sigmoidoscopy with a completion Barium enema. During the study period, colorectal cancer was detected in 4 patients (1.6%), adenomatous polyps in 36 patients (14.4%), and ulcerative colitis in 8 patients (3.2%). In 98 patients (39.2%), no abnormality was present, and in the remaining patients, diverticulosis (n = 60; 24%) and hemorrhoids were present (n = 44; 17.6%).
