Barrett's esophagus(BE) is a change in the esophageal lining and is known to be the major precursor lesion for most cases of esophageal adenocarcinoma(EAC).Despite an understanding of its association with BE for many years and the falling incidence rates of squamous cell carcinoma of the esophagus, the incidence for EAC continues to rise exponentially. In association with this rising incidence, if the delay in diagnosis of EAC occurs after the onset of symptoms,then the mortality at 5 years is greater than 80%. Appropriate diagnosis and surveillance strategies are therefore vital for BE. Multiple novel optical technologies and other advanced approaches are being utilized to assist in making screening and surveillance more cost effective. We review the current guidelines and evolving techniques that are currently being evaluated.

We review the use of Endoscopic Mucosal Resection in the treatment of early colorectal cancer. Newer endoscopic imaging modalities have lead to earlier detection of advanced lesions thus enabling endoscopic curative therapy of lesions that would otherwise need surgery. Early outcomes data suggest promising results. But further long term prospective studies are needed.

AIM To study and describe patients who underwent treatment for gastric antral vascular ectasia(GAVE) with different endoscopic treatment *** We reviewed patients with GAVE who underwent treatment at University of Alabama at Birmingham between March 1, 2012 and December 31, 2016. Included patients had an endoscopic diagnosis of GAVE with associated upper gastrointestinal bleeding or iron deficiency *** Seven out of 15 patients had classic watermelon description for GAVE, 1/15 with diffuse/honeycomb pattern and 6/15 with nodular GAVE per EGD description. Seven out of 15 patients required multimodal treatment. Four out of six of patients with endoscopically nodular GAVE required multimodal therapy. Overall, mean pre-and post-treatment hemoglobin(Hb) values were 8.2 ± 0.8 g/dL and 9.7 ± 1.6 g/dL, respectively(P ≤ 0.05). Mean number of packed red blood cells transfusions before and after treatment was 3.8 ± 4.3 and 1.2 ± 1.7(P ≤ 0.05), *** Patients with nodular variant GAVE required multimodal approach more frequently than non-nodular variants. Patients responded well to multimodal therapy and saw decrease in transfusion rates and increase in Hb concentrations. Our findings suggest a multimodal approach may be beneficial in nodular variant GAVE.
