Qi X, Pan Y, Hu Z, Kang W, Willis J, Olowe K, et al.
J Biomed Opt . 2008 Nov; 13(5):054055. PMID: 19021435
Colonic crypt morphological patterns have shown a close correlation with histopathological diagnosis. Imaging technologies such as high-magnification chromoendoscopy and endoscopic optical coherence tomography (OCT) are capable of visualizing crypt morphology...

Das A, Ben-Menachem T, Farooq F, Cooper G, Chak A, Sivak Jr M, et al.
Gastroenterology . 2007 Dec; 134(1):65-74. PMID: 18061180
Background & Aims: Triage of patients with acute upper gastrointestinal hemorrhage (UGIH) has traditionally required urgent upper endoscopy. The aim of this study is to evaluate the use of artificial...

Overholt B, Wang K, Burdick J, Lightdale C, Kimmey M, Nava H, et al.
Gastrointest Endosc . 2007 Jul; 66(3):460-8. PMID: 17643436
Background: Barrett's esophagus (BE) with high-grade dysplasia (HGD) is a risk factor for development of esophageal carcinoma. Photodynamic therapy (PDT) with Photofrin (PHO) has been used to eliminate HGD in...

Kucera S, Isenberg G, Chak A, Wong R, Das A, Faulx A, et al.
Gastrointest Endosc . 2007 Jun; 66(1):79-83. PMID: 17591478
Objective: To prospectively determine if the current practice of radiologists' interpretation of post-ERCP spot images sent by endoscopists resulted in discrepancies in interpretation, affected subsequent management of patients, and resulted...

Das A, Singh P, Sivak Jr M, Chak A
Gastrointest Endosc . 2007 Mar; 65(7):960-8. PMID: 17331513
Background: Controlled trials support pancreatic-stent placement as an effective intervention for the prevention of post-ERCP acute pancreatitis in high-risk patients. Objective: To perform a decision analysis to evaluate the most...

Das A, Chak A, Sivak Jr M, Payes J, Cooper G
Clin Gastroenterol Hepatol . 2006 May; 4(6):695-700. PMID: 16713744
Background & Aims: Endoscopic ultrasonography (EUS) staging is used for management of esophageal cancer, but its effect on the outcome of patients is unknown. Our aim was to study the...

Boolchand V, Faulx A, Das A, Zyzanski S, Isenberg G, Cooper G, et al.
Gastrointest Endosc . 2006 Jan; 63(2):228-33. PMID: 16427926
Background: Current guidelines recommend consideration of screening patients with chronic GERD for Barrett's esophagus (BE). Unsedated esophagoscopy (UE) is a less costly alternative to standard EGD for identifying BE. The...

Singh P, Chak A, Willis J, Rollins A, Sivak Jr M
Gastrointest Endosc . 2005 Nov; 62(6):970-4. PMID: 16301046
Background: In vivo optical coherence tomography (OCT) imaging has not yet been applied to the pancreatic ductal system. The aim of this study was to obtain in vivo OCT images...

Isenberg G, Sivak Jr M, Chak A, Wong R, Willis J, Wolf B, et al.
Gastrointest Endosc . 2005 Nov; 62(6):825-31. PMID: 16301020
Background: Endoscopic optical coherence tomography (EOCT) is a high-resolution, cross-sectional tissue-imaging technique that provides microscopic morphologic information. EOCT should detect dysplasia in Barrett's epithelium, but this has not been established...

Olds G, Cooper G, Chak A, Sivak Jr M, Chitale A, Wong R
J Clin Gastroenterol . 2005 Mar; 39(4):273-7. PMID: 15758618
Goals/background: Previous studies have demonstrated low yield and conflicting results as to the ability of technetium-99m labeled red blood cell (TRBC) scintigraphy to accurately localize the site of bleeding in...
