Advanced Procedures

Dr. Abousaif is specially trained in the most advanced minimally invasive and non-invasive techniques, which help manage and treat gastrointestinal conditions.

Cellvizio Optical Biopsy

Cellvizio optical biopsy is a groundbreaking technology in the imaging filed. This simple endomicroscopy procedure generates microscopic images of tissue instantaneously and in a minimally-invasive manner, effectively increasing the quality and range of what can be seen. The procedure greatly aids in detecting diseases and identifying appropriate treatments for issues such as:

  • Barrett’s Esophagus
  • Gastric Diseases
  • Biliopancreatic Strictures
  • Pancreatic Cysts
  • Inflammatory Bowel Diseases
  • Colorectal Lesions
  • Lung Nodules
  • Urinary Tract Lesions

Colon Cancer Prevention/Screening

Colon cancer screenings are performed to detect pre-cancerous polyps and other early cancers in the large intestine. This type of screening can find problems that can be treated before cancer develops or spreads. Regular screenings may reduce the risk of death and complications caused by colorectal cancer. There are several different ways to screen for colon cancer, including stool tests and colonoscopies.


This is a safe, non-surgical procedure that allows us to evaluate the lower part of your gastrointestinal tract, including the end of your small intestine, colon, rectum, and anus. A colonoscopy not only screens for colon cancer, but also to investigate a variety of lower gastrointestinal symptoms and disorders.

Esophagogastroduodenscopy (EGD)

EGD is an endoscopic procedure that allows Dr. Abousaif to examine your esophagus, stomach, and duodenum (part of your small intestine). EGD is used to evaluate a number of digestive disorders. It is a popular diagnostic option because patients generally tolerate it well and it causes minimal discomfort.

Flexible Sigmoidoscopy

A flexible sigmoidoscopy is an exam performed to evaluate the lower part of the large intestine (colon). During the exam, a thin, flexible tube is inserted into the rectum. A tiny video camera at the tip of the tube allows Dr. Abousaif to view the inside of the rectum and most of the colon — about the last two feet (61 centimeters) of the large intestine. If necessary, tissue samples (biopsies) can be taken through the scope during a flexible sigmoidoscopy exam.

Hemorrhoid Electrotherapy (HET)

Hemorrhoids are swellings containing enlarged blood vessels that are found inside or around the anal canal. In HET, a probe is used to apply an electric current to the hemorrhoids, which causes them to shrink.

Percutaneous Endoscopic Gastrostomy Placement (PEG)

PEG is an endoscopic medical procedure in which a tube is passed into a patient’s stomach through the abdominal wall, most commonly to provide food, liquids, and/or medications when oral intake isn’t possible or swallowing is difficult.

Small Bowel Enteroscopy

Since evaluation of the small bowel is difficult due to its length and location, a longer scope is necessary for effective visualization, therapeutic and interventional therapies. In some cases, balloons are fitted onto the end of the scope and inflated to examine the more inaccessible areas of the small bowel. This alternative to the more invasive open-abdomen procedure is used to help in the location of gastrointestinal bleeding as well as initial diagnosis of conditions such as Crohn’s disease, celiac disease, and Irritable Bowel Syndrome.

Solesta Injections

These injections are used for the treatment of bowel control problems (also referred to as accidental bowel leakage, or fecal incontinence) in patients 18 years and older who have tried and failed other “conservative” therapies such as changes in diet, fiber therapy, and medications. Solesta is a gel composed of naturally made materials similar to the natural starches, sugars, and tissue in your body. Solesta is an option after conservative methods have failed, but before you consider undergoing surgery.
