“…SPECT/CT can also estimate the length of the gastrointestinal tract leading to the bleeding site and therefore help decide which endoscopic approach to use for further evaluation (57). Furthermore, SPECT/CT helps clarify and avoid the pitfalls that can mimic gastrointestinal bleeding (35). More studies are needed to validate these results.…”

“…Obtaining lateral images or changing the position of the penis can distinguish penile activity from rectal bleeding (35). In addition, variable uterine activity during the ovulatory cycle causes fixed increased perfusion due to endometrial proliferation (76).…”

“…When a dualhead camera is used, simultaneous imaging in the anterior and posterior views may improve the sensitivity for detecting rectal bleeding. Furthermore, lateral views are helpful in differentiating anterior vascular penile activity (which can move or change in intensity during imaging) from bleeding in the more posteriorly located rectosigmoid colon (35).…”

“…Through early coordination of clinical services (such as interventional radiology, gastroenterology, or surgery), the patient can be directed promptly to the next diagnostic or therapeutic procedure if GIBS has positive results (35). Any unnecessary delay increases the likelihood of negative angiography findings, as bleeding often stops spontaneously (33).…”

“…These patients are more likely to benefit from a colonoscopy, which has a yield of 74%-90%, because it is most diagnostic when bleeding is slow or has stopped [14,15] . If unsuccessful in determining the location of the bleed, a radionuclide scanning with (99 m Tc)-labeled red blood cell can be used [17] . Despite the higher sensitivity of nuclear scintigraphy (86%) as compared to angiography and its ability to detect bleeding at rates as low as 0.1 mL/min, its lack of temporal resolution, as well as presence of false positives and error in localization due to presence of reverse peristalsis in the bowel have limited its use in the diagnosis and localization of the LGIB [17] .…”

AIM:To assess if certain triaging rules could be estab lished to optimize the yield of mesenteric angiography. METHODS:Medical records of 101 patients were ret rospectively reviewed and parameters relating to age, gender, pulse rate, blood pressure, serum hemoglobin, intensive care unit (ICU) admission, and the number of packed red blood cells (PRBC) transfused in the 12 and 24 h prior to the angiography were tabulated in two groups with positive and negative angiography results. RESULTS:We found no correlation between gender, pulse rate, blood pressure or serum hemoglobin and positivity of the mesenteric angiogram. But patients with positive angiogram were found to be on average 7 years older (73.2 years vs 65.9 years old) (P = 0.02).Angiogram was positive in 39.3 % (11/28) of patients admitted in ICU vs 23.2% (17/73) who were admitted elsewhere in the hospital (P = 0.03). In the 12 and 24 h prior to angiography, patients with a positive angio gram received a mean of 2.7 ± 2.3 and 3.3 ± 2.6 units of PRBC s respectively, while patients with a negative angiogram had a mean of 1.6 ± 1.9 (P = 0.02) and 2.1 ± 2.6 units (P = 0.04) received respectively in the same period. CONCLUSION:Older age, ICU admission, having re ceived at least 4 units PRBC over 12 h or 5 units over 24 h prior to angiogram are leading indicators for a positive study.© 2014 Baishideng Publishing Group Inc.

We evaluated several factors in 101 patients undergoing mesenteric angiography in a tertiary care institution to see if any could be used for predicting a positive angiogram. We found that vital signs are poor discriminators but older age, intensive care unit admission, having received at least 4 units PRBC over 12 h or 5 units over 24 h prior to angiogram are leading indicators for a positive study. We postulate that the reason is that patients are given enough blood units to compensate for blood loss and stabilize vital signs and therefore the number of blood units given indirectly correlate with severity of active bleeding.Rasuli P, Doumit J, Boulos M, Rizk C, Doumit G.
