Upper GI Endoscopy (EGD)

An EGD (Upper GI Endoscopy) is a procedure performed to directly visualize the lining of the esophagus, stomach and first part of the small intestine (duodenum), using a flexible scope with a camera and a light on the end of it. The scope is passed through the mouth while the patient is sedated.

Zenker Diverticulum

A Zenker’s diverticulum (ZD) is an outpouching that occurs in the esophagus (muscular food pipe that connects the mouth to the stomach). It is thought that high pressure zones in the lumen of the esophagus lead to outpouching formation at a weak point in the top of the esophagus.

High-Resolution Anal Manometry

High-Resolution Anal Manometry evaluates anal sphincter function. It is done to evaluate incontinence and other disorders of defecation, including some forms of constipation. This procedure tests if there are appropriate pushing and relaxation to facilitate defecation and assesses various reflexes that control the sphincter. When done with a balloon expulsion test it can further evaluate the effectiveness of evacuation.

Peroral Endoscopic Myotomy

Peroral Endoscopic Myotomy (POEM) is used to release pressure in the distal esophagus. This can be achieved with an endoscopy, and by carefully cutting the esophageal muscle fibers with special electrocautery knives. POEM effectively replaces the need for a surgical procedure called, Heller Myotomy, which has been conventionally used to treat achalasia. It has the benefit of being less invasive than surgery and having a quicker recovery time.

Wireless Capsule Motility Testing

Wireless capsule motility testing involves swallowing a pill shaped device that sends information wirelessly to a receiver, worn by the patient for the time it takes the capsule to pass through the entire intestinal system.

Transoral Incisionless Fundoplication

First of all, Transoral Incisionless Fundoplication (TIF) is a minimally invasive, anti-reflux therapy for acid reflux disease (GERD). This is also known as heartburn. Furthermore, fundoplication literally means “wrap.” Consequently, during a TIF procedure, part of the stomach is wrapped around the esophagus (food pipe). Lastly, this is to prevent reflux of stomach acid contents upward.

FibroScan

FibroScan works by emitting a pulse of energy, which you may feel as a slight vibration on your skin. FibroScan then measures the speed of this energy and immediately provides this information to your physician, who then uses it as part of a broader evaluation of your liver health.
