The Esophageal Program
Established in 2009, the Northwestern Medicine Esophageal Program represents the fruition of more than two decades of expertise in esophagology.
The program is one of the largest referral points in the Midwest for esophageal function testing, with international observers routinely visiting to learn from our practices.
The program combines all essential elements that are necessary for ongoing clinical excellence and technical innovation: thoughtful clinicians, sophisticated diagnostic testing, clinical research and state-of-the-art surgical practices.
Our physicians and surgeons* authored many of the current guidelines for the treatment and management of GERD (gastroesophageal reflux disease), swallowing disorders and other conditions. Additionally, our investigators have pioneered the most modern diagnostic techniques and therapies, including wireless pH monitoring, high-resolution manometry and natural orifice surgery.
Our surgeons are experienced in various approaches to treating disorders of the esophagus, including minimally invasive and robotic surgery, trans-hiatal and trans-thoracic resection of the esophagus, partial and complete fundoplication for reflux disease, lengthening procedures for complex esophageal repairs, and trans-oral stapling (without an incision) of Zenker diverticulum.
Patients seen in either the Esophageal Program (with benign disease) or in the Robert H. Lurie Comprehensive Cancer Center of Northwestern University (with esophageal malignancy) will receive a comprehensive, multidisciplinary evaluation leading to an individualized plan for the diagnosis and staging of their condition.
The Digestive Health Center works closely with colleagues in allergy, thoracic surgery, surgical oncology, dietary, pathology, radiation and clinical oncology to ensure that the best possible therapies are chosen.
Based on the results of these detailed laboratory, imaging, endoscopic and physiologic investigations and in collaboration with their referring providers, our physicians will develop a personalized plan of treatment designed to address symptoms, maximize quality of life and enhance survival.
Motility Diagnostic Lab
An esophageal motility disorder (EMD) is a disorder of the esophagus that may cause swallowing difficulties, spasms of pain or regurgitation of food. The Motility Diagnostic Lab (part of the Digestive Health Center) treats and diagnoses many types of EMDs, including:
- Spastic esophageal motility disorders: Spastic esophageal motility disorders cause the esophageal muscles to contract and expand abnormally, causing pain and difficulty swallowing. The muscles may be uncoordinated or too weak. Spastic EMDs may include several types:
- Diffuse esophageal spasm: Uncoordinated muscle cramps in the esophagus cause pain in the chest and difficulty sending food to the stomach.
- Nutcracker esophagus: Muscle spasms occur at regular intervals and are coordinated, but the muscle spasms are excessively strong, causing non-cardiac chest pain and occasionally difficulty swallowing.
- Hypertensive lower esophageal sphincter: The lower esophageal sphincter is contracted, causing difficulty swallowing, chest pain, heartburn and regurgitation.
- Nonspecific EMD: This motility disorder contains symptoms of various esophageal motility disorders, but it does not match a pattern.
- Achalasia: Achalasia is a disorder that makes it difficult for patients to swallow solids or liquids due to nerve damage that prevents the sphincter connecting the stomach and esophagus from relaxing. Common symptoms include chest pain, heartburn and regurgitation of food.
- Esophageal scleroderma: This is an autoimmune disorder where the body attacks itself, causing scarring and thickening of the esophagus tissues. This causes abnormal functioning of the smooth muscle of the esophagus, known as esophageal scleroderma.
The Motility Diagnostic Lab offers diagnostic testing for EMDs, including:
- Oropharyngeal motility (swallowing) study: This is a study in which the patient is given small amounts of a liquid containing barium to drink with a bottle, spoon or cup. A series of X-rays is taken to evaluate what happens as the liquid is swallowed.
The Esophageal Program focuses on benign and malignant disorders of the esophagus, including GERD, hiatal hernia, achalasia, Barrett's esophagus, diverticula, tumors and esophageal cancers.
Our current research focuses on esophageal and oropharyngeal physiology and pathophysiology, including:
- Oropharyngeal studies are aimed at describing the normal mechanics of swallowing and the modifiability that can be imposed therapeutically. These studies use computerized analysis of manometric and videofluorographic swallowing studies.
- Pathophysiologic studies of the oropharynx focus on mechanisms that result in dysphagia and the efficacy of volitional compensatory strategies in modifying these defects.
- Analysis of esophagogastric junction pathophysiology, through the use of high-resolution, solid-state manometry, with respect to reflux disease and esophageal motor disorders.
Previous research interests have included central nervous system neurophysiology, autonomic nervous system neurophysiology as it relates to sodium homeostasis, and screening for esophageal cancer.
Jorge Sobenes is a husband and father who loves to cook for his family. In a nine-month period, however, he went from enjoying his favorite foods to not being able to eat or drink due to a tightening in his throat and difficulty swallowing. He lost 40 pounds and was desperate for answers. Sobenes was diagnosed with achalasia, a condition where the esophagus is unable to move food into the stomach, and was told he would need surgery.
Historically, the procedure requires several incisions in the abdomen in order to access the blocked esophageal pathway. Sobenes, however, was able to undergo surgery without any external incisions thanks to an innovative new approach called PerOral Esophageal Myotomy (POEM). The procedure is one of a growing number of surgeries to use the body’s natural orifices as an entry point, thus eliminating the need for traditional incisions. Northwestern Medicine and its Digestive Health Center is one of only a few centers in the U.S. with surgeons trained to perform the procedure.
“This surgical approach not only eliminates the need for external incisions, but also offers greater precision and a faster healing time for patients,” said Eric Hungness, MD, gastrointestinal surgeon at Northwestern Memorial Hospital.
POEM is performed by inserting an endoscope in the mouth and tunneling it down the esophagus so surgeons can access and cut abnormal muscle fibers that prevent the valve at the base of the esophagus from opening to allow food to enter the stomach. Over the past three years, over 90 POEM procedures have been performed by Hungness and colleagues at Northwestern Memorial Hospital with excellent results. Their team recently presented one of the largest experiences to date at the SAGES national meeting demonstrating a 92 percent success rate.
Sobenes, who was one of the first patients in the country to be treated for achalasia using the new procedure, said the choice was easy for him. “What I was going through was terrible. I couldn’t eat. I couldn’t drink. I wanted to get back to normal as fast as possible and was happy to hear of this alternative,” said Sobenes.
More than 3,000 people are diagnosed with esophageal achalasia each year. The Northwestern Medicine Digestive Health Center is one of the leading regional and national referral centers for achalasia and other swallowing disorders. The most common symptom is difficulty eating solid food and drinking liquids. As it advances, achalasia can cause considerable weight loss and malnutrition. Common treatments for esophageal achalasia include traditional surgical approaches, such as a Heller myotomy or a balloon dilation. POEM has been shown to have comparable or better short-term outcomes to these alternatives.
“Previously, we had to make at least five incisions in a patients abdomen in order to treat esophageal achalasia surgically,” said Hungness. “Although the research continues and long-term results are not known, POEM holds great promise for patients and demonstrates the bright future for incisionless surgeries.”
Approximately 2,000 POEM procedures have been performed in the world since 2008. Hungness, together with Nathaniel Soper, MD, chief of surgery on the medical staff at Northwestern Memorial Hospital, have been among those pioneering new minimally invasive procedures including POEM. Doctors stress that treatment options must be carefully selected based on the unique needs of the patient but say minimally invasive procedures such as POEM have been shown to offer an array of potential benefits including greater surgical precision, a shorter recovery time, shorter hospital stay, and less pain.
“This is the future of surgery,” said Soper. “With each new procedure, we learn how to apply the technique and technology to other surgeries and develop new tools.”
