Services & Treatments

The gastroenterology and colorectal specialists at Advocate Illinois Masonic Medical Center’s Digestive Health Institute work to prevent and treat a range of gastrointestinal tract diseases using the most minimally invasive and innovative procedures available.

Diagnostic and Interventional Endoscopy in the GI Lab
We offer diagnostic and interventional endoscopy. During diagnostic endoscopy procedures, your physician uses a flexible tube called an endoscope to see the inside of your gastrointestinal tract and look for polyps or other problems.

Diagnostic Endoscopy

In a diagnostic endoscopy, your physician looks at the lining of the gastrointestinal tract utilizing an endoscope, a thin, flexible tube with a tiny light and camera at the end of it. Your physician passes the endoscope into your intestines through either your esophagus or rectum to see an image of your intestinal tract on a monitor.

  • Anorectal manometry (3D): A procedure used to measure the muscle contractions in your anus and rectum
  • Capsule endoscopy: A procedure in which you swallow a capsule with a camera on it, which takes pictures of the inside of your GI tract
  • Colonoscopy: An internal examination of the colon
  • Esophageal manometry (3D): A procedure used to measure the muscle contractions in your esophagus
  • Esophageal 48-hour pH monitoring: A procedure used to measure the regurgitation or backwash of acid from your stomach into your esophagus
  • Esophagogastroduodenoscopy (EGD): An internal examination of the lining of your esophagus, stomach and upper duodenum
  • Flexible sigmoidoscopy: An internal examination of the inside of the lower portion of your colon, called the sigmoid colon
  • Upper endoscopy: An internal examination of the upper part of your GI tract in which the endoscope is passed through your mouth and throat and into your esophagus

Interventional Endoscopy

With interventional endoscopy procedures, physicians can take tissue samples or do other minor surgical procedures while examining your GI tract. This means quicker treatment and recovery for patients, as well as a lower risk for complications compared to traditional surgery.

  • Colonic stent placement: Insertion of a small tube to hold open a colon obstruction and allow food and liquid to pass through more easily
  • Endoscopic mucosal resection (EMR): A procedure in which a physician removes cancerous tissues or lesions from a patient’s digestive tract
  • Endoscopic retrograde cholangiopancreatography (ERCP): A procedure used to identify stones, tumors or narrowing in the bile ducts
  • Esophageal stent placement: Insertion of a small tube to hold open a blocked or narrowed part of the esophagus to help a patient swallow more easily
  • Endoscopic ultrasound (EUS) with fine needle aspiration: A procedure in which a physician inserts an endoscope and gathers ultrasound images of the inside of the digestive tract; a needle can be used to aspirate tissue and obtain cells that can be analyzed for signs of cancer or other problems
  • Laparoscopic-assisted endoscopic polyp removal: A minimally invasive procedure used to remove polyps
  • Percutaneous endoscopic gastrostomy (PEG tube): Insertion of a feeding tube through the abdominal wall into the stomach during an EGD
  • Radiofrequency ablation therapy (Barrx™ HALO): A minimally invasive treatment for Barrett’s esophagus, a condition that can lead to esophageal cancer. In this procedure, a physician uses an endoscope to insert a catheter that generates short bursts of high energy to burn away a thin layer of damaged tissue around the circumference of the esophagus.
  • Trans Oral Incisionless Fundoplication (TIF): A procedure that reconstructs the antireflux valve using an EsophyX™ device and restores the body’s natural protection against reflux. The EsophyX™ device and the endoscope are gently inserted through the mouth to form and fasten tissue folds to reconstruct the antireflux valve at the junction of the esophagus and the stomach.

Medical, Diagnostic and Surgical Procedures for Colorectal Care
Although not all colorectal diseases are curable, many can usually be treated successfully, especially if detected early. The colorectal surgeons at Advocate Illinois Masonic Medical Center are compassionate professionals, skilled at detecting problems and using the least invasive treatment methods.

When treating diseases and disorders of the colon and rectum, we use lifestyle changes, medical treatments and the most advanced technology available. With an emphasis on preserving sphincter control and avoiding the need for permanent stomas, our team creates an individualized treatment plan to get you back to a normal lifestyle as soon as possible.

Diagnostic Procedures and Technologies

  • Anal physiology lab
  • Anorectal manometry (3D): A procedure used to measure the muscle contractions in the anus and rectum
  • Biofeedback: A technique used to help patients learn to control their body's functions by using electrical sensors that receive information (feedback) about the body (bio)—this feedback helps patients focus on making subtle changes in their bodies, such as relaxing certain muscles, to achieve desired results
  • Colonoscopy: An internal examination of the colon
  • Defecography: A radiological test that allows the doctor to visualize what occurs when you are emptying your rectum to help with diagnosis
  • Flexible sigmoidoscopy: An internal examination of the inside of the lower portion of the colon, called the sigmoid colon
  • Sitz bath

Medical and Surgical Procedures

  • Artificial anal sphincter placement
  • Da Vinci® robotic surgery
  • Endoscopic ultrasound (EUS) with fine needle aspiration: A procedure in which a physician inserts an endoscope and gathers ultrasound images of the inside of the digestive tract. A needle can be used to aspirate tissue and obtain cells that can be analyzed for signs of cancer or other problems.
  • Endo-anal rectal ultrasound (3D)
  • Hyperthermic intraperitoneal chemotherapy (HIPEC)
  • Ileal pouch-anal anastomosis
  • Image-modulated radiation therapy (IMRT)
  • Image-guided radiotherapy (IGRT)
  • InterStim® anal electrical stimulation therapy
  • Laparoscopic colon resections and surgery
  • Neuromodulation therapy
  • Rubberband ligation
  • Sphincter-preserving surgery
  • Surgical muscle repair
  • RapidArc® radiotherapy: A revolutionary technology that delivers more precise radiotherapy than conventional treatments for those with colorectal cancer. While reducing the traditional 10- to 15-minute treatment down to two minutes, it minimizes the chance of tumor movement during treatment, decreases the actual dose of radiation to the patient, reduces the scattering of radiation outside the tumor and preserves more healthy tissue than conventional radiotherapy.
