BACKGROUND: Lower endoscopy (LE) is the standard diagnostic modality for lower gastrointestinal bleeding (LGIB). Conversely, computed tomographic angiography (CTA) offers an immediate non-invasive diagnosis visualizing the entire gastrointestinal tract. The aim of this study was to compare these 2 modalities with regards to diagnostic value and bleeding control. METHODS: Tertiary center retrospective analysis of consecutive patients admitted for LGIB between 2006 and 2012...

Acute lower gastrointestinal bleeding usually presents as hematochezia, rectal bleeding or melena and represents 1-2% of the medical appointments in the Emergency Services. Mortality reaches the 30-40% and it is highly related with the severity and associated comorbidity. Most clinical practice guidelines include colonoscopy at some point in the diagnostic and therapeutic process (urgent for severe cases and ambulatory for mild ones) and look for predictors of severity. In the last years, there have been numerous studies where is clear the relevance and complementarity of advanced diagnostic imaging techniques, gradually incorporated as an alternative or second step in severe cases...

BACKGROUND AND AIMS: There are limited data to predict which patients with lower gastrointestinal bleeding are at risk for adverse outcomes. We aimed to develop a clinical tool based on admission variables to predict 30-day mortality in lower gastrointestinal bleeding. METHODS: We used a validated machine learning algorithm to identify adult patients hospitalized with lower gastrointestinal bleeding at an academic medical center between 2008 and 2015. The cohort was split randomly into a derivation and validation cohort...

BACKGROUND: Anemia is defined as hemoglobin below the cutoff of normal in studies examining the gastrointestinal (GI) tract in iron-deficiency anemia (IDA). Although the risk of GI cancer (GIC) increases as hemoglobin decreases, guidelines do not usually recommend hemoglobin thresholds for IDA investigation. METHODS: To elucidate whether underlying GI disorders explain the different hemoglobin values and clinical outcomes observed initially in IDA patients referred for GI workup, we prospectively investigated the diagnostic yield of a thorough GI examination in consecutive IDA adults with predefined hemoglobin <9g/dL and no extraintestinal bleeding...

BACKGROUND: Bleeding from the small bowel is a rare pathology that represents 5-10% of gastrointestinal bleeding; 0.06% to 5% of cases are due to the presence of diverticula of the small intestine. The majority of diverticula are asymptomatic and present symptoms when there is a complication. CLINICAL CASE: We present the case of a 53-year-old male with a history of chronic renal failure and hypertension. While he was hospitalized due to cerebrovascular disease he recurrently presented lower gastrointestinal bleeding that required blood transfusion on several occasions...

Lower gastrointestinal bleeding is most commonly associated with diverticulosis, ischemic colitis, vascular ectasia, and anorectal disease and less commonly associated with colonic malignancy. Infrequently, it is associated with mesenteric varices, a rare etiology that is not well documented in the radiology literature. We present a case of a 50-year-old man diagnosed as having intermittent left colonic bleeding from mesenteric varices due to a critical stenosis at the portal vein-inferior mesenteric vein confluence...

BACKGROUND: The U.S. medical malpractice system assumes that the threat of liability should deter negligence but it is unclear whether malpractice environment impacts healthcare quality. We thus sought to explore the association between state malpractice environment and post-operative complication rates. STUDY DESIGN: This observational study included Medicare fee-for-service beneficiaries undergoing one of the following surgeries in 2010: colorectal, lung, esophageal, or pancreatic resection, total knee arthroplasty, craniotomy, gastric bypass, abdominal aortic aneurysm repair, coronary artery bypass grafting, or cystectomy...

Gastrointestinal bleeding from non-Meckel's small bowel diverticulosis is uncommon. Depending on the diverticulum's location, a patient's presentation can suggest either an upper or lower gastrointestinal source. We present two cases of bleeding from non-Meckel's small bowel diverticula. One patient was managed successfully with endoscopic therapy, and the second required surgical resection after two failed attempts at achieving hemostasis endoscopically.
