The role of colonoscopy in the diagnosis and management of lower intestinal bleeding.

Colonoscopy and roentgenographic studies are complementary techniques in the evaluation of disorders involving the large bowel. The exact roles of these methods in the diagnosis and management of lower intestinal bleeding, however, remain to be established. In this paper, we have formulated various roles for colonoscopy in lower intestinal hemorrhage depending upon the rate and activity of the bleeding according to whether the episode is: 1) recent minor bleeding or recurrent minor or occult bleeding; 2) severe bleeding which has stopped; 3) severe and active bleeding. In addition, we discuss colonoscopic therapy of bleeding lesions and intraoperative endoscopy of the small and large bowel.

Flexible sigmoidoscopy: diagnostic yield in 1015 patients.

The purposes of our study were to 1) identify the number of neoplastic lesions (adenomatous polyps and cancer) diagnosable by flexible sigmoidoscopy (FS) in patients with symptoms of colorectal disease and 2) determine the age distribution of patients in whom neoplastic lesions are detected by FS. A total of 1015 patients, ages 20-89 years, underwent FS because of the following indications: rectal bleeding, occult blood loss, anemia, change in bowel habit, weight loss, and abdominal pain. FS examined a mean distance of 49 +/- 2 cm (SEM) in an average time of 11.5 min. A bowel preparation of 2 Fleet enemas was adequate in 95% of patients and the examination was well tolerated by all age groups. There were no complications encountered. Eight-five neoplastic lesions were identified in 78 patients. Fifty-four percent of all adenomatous polyps and 61% of the cancers were detected beyond 20 cm. Neoplastic lesions were identified in all adult decades studied, ranging from 3.2% of patients aged 20-40 years, 8.0% for patients between 40 and 60, and 10.1% from 60 to 80; with a peak yield of 11.2% in the 7th decade. Cancer was diagnosed only in patients more than 40 years; 3.3% of patients over 60 had carcinoma compared to 0.8% in patients less than 60. These data provide evidence for the value of FS as a safe initial diagnostic procedure to detect neoplastic lesions in symptomatic patients of all adult age groups.

Anatomical extent of fiberoptic sigmoidoscopy.

The anatomical extent of fiberoptic sigmoidoscopy was determined by placing a clip on the colonic mucosa and subsequently locating the clip on barium enema. A 60 cm exam viewed the entire sigmoid colon in 81% of patients. Exams of 50-55 cm, 40-45 cm, and 30-35 cm extent viewed the entire sigmoid colon in 68%, 27%, and 13%, respectively. The 50-55 cm and 60 cm exams collectively viewed 90% and 95% of the sigmoid colon surface, respectively. The 30-35 cm and 40-45 cm exams collectively viewed 53% and 70% of the sigmoid colon surface respectively. The anatomical extent of fiberoptic sigmoidoscopy clearly exceeds that of rigid sigmoidoscopy. These data help to define the diagnostic potential of fiberoptic sigmoidoscopy.
