I have never had a doctor that has fulfilled my needs as a patient. I want and need a doctor that knows what they are doing and he does. Thank you so very much."

Since Dr. Gordon arrived in Mexico, MO in 1990, there has been a lot of change in his medical practice. He has added a large Research Department to his clinic. This Research Department is currently active in over 20 Clinical Research Protocols that are all FDA-approved. These research clinics are often spread across the U.S., as well as in other countries. Dr. Gordon's clinic is often the only site in the state of Missouri for the majority of these trials.


Dr. Gordon's clinic currently employs Matt Burkemper, Study Coordinator; Matt Quintero, Study Coordinator; Amy Hill, LPN, Study Coordinator and Brenda Gordon, RN, BSN.


Dr. Gordon is well educated and is board certified as a Diplomat by the American Board of Internal Medicine in Internal Medicine as well as Gastroenterology.


The clinic has a very devoted professional and highly trained staff that works both in the Research Department and the Clinic. The clinic has seen new drugs approved by the FDA due to the outstanding research efforts they have provided. The Center had about 20 patients in the Humira trials for Crohn's patients. Most of these subjects completed anywhere from 4 to 12 years of participation in the studies at the clinic. It was very exciting for the staff and subjects to see how eachother reacted to this new innovative medication. Dr. Gordon feels he has advantages over others that don't get to work with research, in that he is already experienced with the drugs before they are even out on the market. The entire clinic is excited for the subjects that get to participate, and there are many subjects that are very glad they opted to participate in studies. There are many patients that will tell of their postitive experience in research protocol. One subject drove from Olathe, KS to participate in a Crohn’s Study, and then relocated to Canada. She continued to come to Dr. Gordon’s Research Clinic even though she was offered to transfer to a Canadian Research Site that would be more convenient. She loved Dr. Gordon and his research staff and was not going to transfer over to any other clinic. She continued to come in to the clinic for her research visits until the study was closed because the drug was FDA approved and available for commercial use for Crohn’s Disease.


Dr. Gordon’s Center conducts clinical research trials in the areas of IBD (inflammatory bowel disease) including Crohn’s disease and ulcerative colitis, IBS (irritable bowel syndrome with diarrhea or constipation), C-Diff (clostridium difficile), idiopathic or diabetic gastroparesis, and GERD. Clinical research trials are an opportunity for patients to be evaluated and treated with cutting edge therapy in controlled, FDA-approved protocols.  These protocols are used to investigate the safety and effectiveness of medication on patients in their disease state.  The studies and the medications involved may help patients recover from these conditions.


These research trials are not only beneficial for the patient individually, but the medical community as a whole. New treatments and medications are being approved by the FDA at a rapid pace thanks to the doctors and their patients’ involvement in these studies. One example is Humira, a medication now approved for the effective treatment of Crohn’s disease and more recently ulcerative colitis, which was tested right here in Mexico, Missouri.


Since he started conducting clinical research in 1992, Dr. Gordon has been selected to conduct hundreds of studies.  Most of these focus on the digestive issues that his clinic specializes in, but some address other issues, like gout.  The studies can last as few as 8 weeks or as long as 7 years, possibly longer.  Regardless of the length of time, being involved in medical research, from a physician’s standpoint, takes a certain dedication that a regular clinical practice may not always demand.  Dr. Gordon attends many educational research seminars, meetings and even delivers multiple keynote addresses on topics of interest at conferences in the US.  


“More than anything, I want the people in Mexico and surrounding communities to know what we are doing at our clinic. We are on the cutting edge and striving everyday to help people who are suffering from terrible conditions & problems that may not respond to traditional therapy.”  


Dr. Gordon performs quality medical care to patients with a variety of problems relating to the digestive system such as nausea, vomiting, diarrhea, constipation, change in bowel habits, rectal pain, rectal bleeding, hemorrhoids, abnormal weight loss or abnormal weight gain, loss of appetite, acute or chronic pancreatitis, abnormal liver function blood tests, hepatitis, nervous stomach, abdominal pain and/or burning, chest pain – non-cardiac, difficulty or painful swallowing, indigestion/heartburn, bloating and/or excess gas, blood in the stool, ulcers, diverticulosis, diverticulitis, colon polyps, irritable bowel, inflammatory bowel disease such as Crohn’s disease and ulcerative colitis.


Dr. Gordon has the capabilities to perform flexible sigmoidoscopy, anoscopy, proctoscopy and capsule endoscopy at his clinic, the Center for Digestive & Liver Diseases, Inc.  The capsule endoscopy has its own camera and light source and records video of the GI tract for 8 hours. In addition to videoing the esophagus, stomach, and colon, it is used as a diagnostic aid for viewing the small intestine, a very difficult proposition until recent innovations.  This procedure can be useful in diagnosing patients that need to have the small intestine evaluated due to persistent symptoms such as abdominal pain, diarrhea, bleeding or anemia. It is also used to evaluate the small intestine in certain chronic gastrointestinal diseases such as Crohn’s disease. Capsule endoscopy also allows the doctor to obtain information regarding the motility of the GI tract by showing how long it takes for the capsule to travel through the stomach and small bowel. It is ideal for patients that are unable to tolerate a traditional EGD or colonoscopy.  The capsule endoscopy requires very little preparation, so it is easier to tolerate than a colonoscopy preparation.  The patient comes to the office in the morning, and picks up a capsule that has a very tiny camera in it. The patient swallows the capsule just like any pill.  The capsule is comparable in size to a vitamin. The patient then simply attaches a monitor to the outside of their body and they’re off to enjoy a normal day.  They must only return to the clinic in the afternoon to remove the monitor. The capsule travels through the GI tract and is eliminated naturally through a bowel movement. The patient does not feel it pass, and most often won’t even notice it as it is not always visible within the stool. Retrieval of the capsule is not necessary as it is disposable.


For added convenience, Dr. Gordon does esophagogastroduodenoscopies (EGD) and colonoscopies at Audrain Medical Center, Surgery Center of Columbia and Hannibal Regional Hospital allowing the patient to decide where to have their study procedure if protocol instructed.


In our research clinic, we currently only have studies for adults 18 years of age and older.  Please contact the Center for Digestive and Liver Diseases, Inc if you are interested to learn more about the research trials currently enrolling to see if you might be eligible.
