One hundred and forty four patients underwent colonoscopy to detect the cause of rectal bleeding. This was successful in either identifying the lesion or excluding the presume of lesions up to the cecum in 88.8% patients. The source of bleeding was diagnosed in 106 (73.61%) patients. Predominant lesions were nonspecific colitis and ulcers (62.26%), polyps (17.92%), cancer (8.49%), rectal varices (3.77%) and tuberculosis (1.88%). The remainder had other colonic conditions such as radiation colitis, ischemic colitis, vascular malformation, diverticulosis, right sided ulcerative colitis and pseudo-pancreatic cyst communicating with the descending colon. The majority (94.33%) of these lesions involved the left colon. Thus colonoscopic examination was useful in localizing the cause of rectal bleeding and the predominant lesions were differed from those reported in the western hemisphere.
144例患者接受了结肠镜检查以查明直肠出血的原因。在88.8%的患者中，该检查成功识别出病变或排除了直至盲肠的病变推测。106例（73.61%）患者的出血源得到诊断。主要病变为非特异性结肠炎和溃疡（62.26%）、息肉（17.92%）、癌症（8.49%）、直肠静脉曲张（3.77%）和结核病（1.88%）。其余患者患有其他结肠疾病，如放射性结肠炎、缺血性结肠炎、血管畸形、憩室病、右侧溃疡性结肠炎以及与降结肠相通的假性胰腺囊肿。这些病变大多数（94.33%）累及左半结肠。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。
