Esophagogastroduodenoscopy (EGD)

An upper esophagogastroduodenoscopy enables the physician to see inside the esophagus, stomach and duodenum. This diagnostic tool is used to analyze swallowing, difficulties, nausea, vomiting, reflux, bleeding, indigestion, abdominal pain or chest pain. Biopsies can be obtained for further analysis. A sedative and pain medication is normally used for patient comfort.

Diagnostic/Screening Colonoscopy

A colonoscopy is a procedure allowing physicians to examine the entire colon, from the rectum to the lower end of the small intestine. Using a lighted flexible tube with a tiny camera that transmits pictures of the colon to a video screen, the doctor examines the colon for ulcers, swelling, and polyps. the physician can also take small tissue samples to look for infection, illness, early signs of cancer, and also to remove polyps. Removed polyps are examined closely to determine if they are pre-cancerous. During a colonoscopy procedure patients receive mild sedative and pain medication for comfort. A registered nurse monitors vitals signs ans assists the doctor during the procedure.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP allow physicians to examine gastrointestinal bile duct systems of the liver, gallbladder and pancreas. Useful in diagnosing and treating problems causing jaundice, abdominal pain and many pancreas and bile duct system problems can be identified and corrected. Tumor diagnosis and biopsy, stone removal, and using endoscopic balloons or stent placement can open strictures or scarring. Performed in the radiology suite, ERCP employs a lighted flexible tube with a tiny camera that transmits pictures to a video screen. X-rays are also used with the endoscope to obtain a complete picture of the bile duct systems. ERCP procedures are performed under general anesthesia to ensure patient safety and comfort. The anesthesia team will be present to administer the medications.

Percutaneous Endoscopy Gastrostomy Placement

Placement of a gastrostomy tube is required for patients who are unable to consume sufficient calories. Required for patients who are unable to eat or swallow enough nutrition. The gastrostomy tube is placed through the abdomen into the stomach and can be used for nutrition, fluids and medications. A gastrostomy can be used for a short time or long-term for patients with diagnoses such as Amyotrophic Lateral Sclerosis (ALS - Lou Gering's Disease), facial trauma, dysphasia, and tumors of the head and neck. Physicians use a lighted flexible tube through the mouth and into the stomach to place the tube. Usually, during gastrostomy tube placement procedure patients receive a mild sedative and pain medication for comfort.
