The range and distribution of sources of lower gastrointestinal bleeding (LGIB) seem to be evolving over time. Ischemic colitis (IC) has long been recognized as a common cause of LGIB. Due to a variety of contributing factors, we suspect that IC may be implicated in an increasing proportion of inpatient cases of lower GI bleeding compared to previously published rates. We examined the medical records of 464 patients admitted to the Methodist Hospital from 2005 to 2013. Patients with LGIB admitted to the hospital with a diagnostic colonoscopy were eligible for the study. Demographics and diagnoses were grouped and categorized for ease of comparison and compatibility with prior studies. Statistical analysis was used to summarize disease distribution and calculate probability outcomes based on pooled mean values obtained from 6 previously published epidemiological studies of LGIB. Anorectal bleeding including hemorrhoids, fissures, and stercoral ulcers was the most frequent diagnosis overall (20%) followed by ischemic colitis (16%) and diverticulosis (14%). There were a significantly higher proportion of IC cases observed in our population compared to the expected proportion of cases (p < 0.01, 95%). When stratified by sex, IC was the leading overall cause in females.

Background: We assessed the value of selective arteriography in the diagnosis and management of acute gastrointestinal hemorrhage. Methods: We reviewed the records of 107 consecutive patients who had gastrointestinal hemorrhage and underwent selective arteriography between January 1992 and October 2003: 10 had upper gastrointestinal bleeding, 79 had lower gastrointestinal bleeding, and 18 had varicose bleeding with portal hypertension. Selective embolization was attempted in 15 patients to obtain hemostasis. Angiographic findings were reviewed and prospective reports were compared with the final diagnosis and outcome. Results: Of 129 angiographic studies, 36 correctly revealed the bleeding site and 93 were negative. Extravasation was seen in 24 cases at the level of stomach (n = 2), duodenum (n = 1), small bowel (n = 5), or colon (n = 16). Indirect signs of bleeding sources were identified in 12 patients (stomach in one, small bowel in four, large bowel in four, liver in three). Transcatheter embolization induced definitive hemostasis in 11 of 15 patients (73%), namely in the stomach (n = 2), small bowel (n = 3), colon (n = 7), and liver (n = 3). Three patients required surgery after embolization. Conclusion: Abdominal arteriography may localize gastrointestinal bleeding sources in approximately one-third of cases. Selective embolization may provide definitive hemostasis in most instances.
