A 62-year-old male presented with complaints of daily heartburn and chest discomfort. These symptoms had been ongoing for seven to eight years but had worsened over the last few months. He underwent an upper endoscopy and Barrett's esophagus was diagnosed.

A 59-year-old male was diagnosed with Barrett's esophagus five years ago. On his last surveillance endoscopy, random biopsies of Barrett's mucosa showed low-grade dysplasia. The patient was referred to IESMG for further evaluation and treatment.

A 66-year-old white male was diagnosed with Barrett's esophagus. Endoscopy and biopsies showed an area of nodular high-grade dysplasia. At IESMG, he underwent endoscopic mucosal resection (EMR) of the nodular area with success. He is now considered for ablation of residual Barrett's esophagus.

A 78-year-old male ex-smoker with emphysema and a long-standing history of GERD was found on upper endoscopy to have Barrett’s esophagus with a focal area of raised mucosa. A 1 cm nodular lesion was identified along a “tongue” of Barrett’s mucosa.

A 63-year-old male with chronic GERD was diagnosed to have circumferential Barrett’s involving a 4 to 5 cm segment of the distal esophagus. Biopsies showed high-grade dysplasia, confirmed by a second pathologist.

A 60-year-old man with cirrhosis secondary to alcoholic liver disease presented with a history of multiple gastrointestinal bleeds over a three-year period. The patient had a history of both esophageal and gastric varices and had undergone multiple episodes of esophageal variceal band ligation.

An 80-year-old male with a history of multiple endocrine neoplasia type 1 presented to an outside hospital with burgundy stool. He had a history of gastric varices secondary to thrombosis of the portal and splenic veins.

A 71-year-old male with cryptogenic cirrhosis and hepatocellular carcinoma was transferred from an outlying hospital with acute GI bleeding. He underwent portal decompressive surgery one year earlier for variceal bleeding.

A 42-year-old male with a history of necrotizing biliary pancreatitis complicated by splenic vein thrombosis presented with episodic transfusion-dependent melena. Multiple upper and lower endoscopies, RBC tagged scans, and small bowel radiographs were unrevealing of a bleeding source.

An 83-year-old male with a history of iron deficiency anemia underwent upper endoscopy and was found to have a 3 cm sessile adenoma in the second portion of the duodenum extending over two folds. Biopsies showed tubular adenoma without dysplasia. He was referred to IESMG for consideration of mucosectomy.

A 54-year old female who underwent screening colonoscopy was found to have a 5 cm adenomatous growth encompassing the hemicircumference of the sigmoid colon. Biopsies showed a tubular-villous adenoma. She was referred for mucosectomy.
