According to the National Cancer Society, 1 in 17 men and 1 in 19 women will be diagnosed with Colon or Rectal Cancer during their life time. Fortunately, these types of cancer are treatable with early diagnosis. "With modern screening tests that are available at Medical Center of Lewisville, we have all of the modalities to check for precancerous conditions at a very treatable stage," says colorectal surgeon, Dr. Hasan Hashmi. "We can identify at risk patients and screen to detect tumors before they reach an untreatable stage." Medical Center of Lewisville offers a complete spectrum of care with a comprehensive team of physicians including colorectal surgeons, gastroenterologist and oncologists. From diagnosis to treatment, you will receive the best care possible from a team you can trust.

Manometry: Esophageal & Anorectal

Medical Center of Lewisville utilizes several new options in the treatment and diagnosis of Colorectal and Gastrointestinal Disease including Manometry. This is a method of studying the pressure wave forms seen in the GI Tract to evaluate disorders of peristalsis and sphincter function. Anorectal Manometry is used to evaluate patients with anal sphincter disorders such as incontinence and constipation. It is also valuable in the follow up of those patients who undergo reconstructive surgery of the anal sphincter. These tests are also valuable in analyzing prior to rectal resections if a patient will be able to have effective control.

Capsule Endoscopy


Capsule Endoscopy allows your doctor to examine the lining of the middle part of your gastrointestinal tract, which includes the three portions of the small intestine (duodenum, jejunum, ileum). This part of the bowel cannot be reached by traditional upper endoscopy or by colonoscopy. The most common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine. It may also be useful for detecting polyps, inflammatory bowel disease (Crohn’s disease), ulcers, and tumors of the small intestine. Your doctor will use a pill sized video capsule called an endoscope, which has its own lens and light source and will view the images on a video monitor. You might hear your doctor or other medical staff refer to capsule endoscopy as small bowel endoscopy, capsule enteroscopy, or wireless endoscopy.

Esophageal pH Testing

Doctors at Medical Center of Lewisville are employing innovative technology to conduct pH testing to measure the degree of acidity or alkalinity in the esophagus of patients suffering from gastroesophageal reflux disease. Through a procedure involving the Bravo™ Delivery System, a pH probe is inserted via a patient’s mouth or nose and positioned above the lower esophageal sphincter where it can measure the amount and degree of acidity and how often stomach acid flows into the lower esophagus. Once the pH probe is in place, doctors can generate suction, draw a small amount of esophageal tissue into the probe and lock it in place. The physician then withdraws the pH probe and can begin measuring pH levels with minimal discomfort to the patient.

pH Monitoring:

  • Allows 48-hour or 24-hour pH monitoring
  • Enhances patient comfort and convenience
  • Eliminates throat discomfort associated with trans-nasal pH catheters
  • Patients are able to maintain normal diet and activity levels
  • Miniature pH probe transmits data to pager-sized receiver
  • Attaches to the esophagus and stays in one place
