Two hundred and forty consecutive patients with recurrent lower gastrointestinal bleeding were studied by colonoscopic examination. These included 187 adults and 53 children. The procedure was successful either in identifying the lesion or in excluding it up to the cecum in 216 (90% patients). The source of bleeding was identified in 138 (74%) adults and 43 (81%) Children. Predominant lesions in adults were nonspecific colitis and ulcers (58%), polyps (19%), cancer (10%), rectal varices (4%) and tuberculosis (3%). Juvenile polyps (77%) and nonspecific colitis and ulcers (23%) were the cause of bleeding in children. Both in adults and children, 92% of these lesions involved the left colon. Rectum and sigmoid colon were mainly involved. Diffuse lesions were seen when nonspecific colitis and ulcers were the source of bleeding. Thus colonoscopic examination was useful in localizing the cause of rectal bleeding and the predominant lesions were different from those reported in the Western hemisphere.
对240例连续性复发性下消化道出血患者进行了结肠镜检查。其中包括187名成人和53名儿童。该检查成功识别病变或排除直至盲肠的病变达216例（90%的患者）。138例（74%）成人和43例（81%）儿童的出血源得到了确认。成人的主要病变是非特异性结肠炎和溃疡（58%）、息肉（19%）、癌症（10%）、直肠静脉曲张（4%）和结核病（3%）。儿童出血的原因是幼年息肉（77%）和非特异性结肠炎及溃疡（23%）。成人和儿童中，这些病变的92%累及左半结肠。主要累及直肠和乙状结肠。当非特异性结肠炎和溃疡为出血源时可见弥漫性病变。因此，结肠镜检查有助于定位直肠出血的原因，且主要病变与西半球报道的不同。
