Our Service

Our center is equipped with advance equipment to provide services for patients with symptoms and disorders related to the gastrointestinal motility such as GERD, constipation, and fecal incontinence. Our services are as follows; 

High Resolution Esophageal Impedance Manometry (HRIM)

  • Measures pressures and fluid movement in the esophagus from upper to lower esophageal sphincter
  • UES
    • Degree of UES relaxation
    • Magnitude of the intrabolus pressure
    • Presence or absence of pharyngeal peristalsis
  • Esophagus
    • Propagation of the pressure waves and the contractile vigor of the pressure waves
    • Bolus transit and clearance
  • LES
    • LES location
    • LES pressure and relaxation

24-hour pH/Impedance Reflux Monitoring

  • Ambulatory Combined Multichannel Intraluminal Impedance and pH (MII-pH) Monitoring
  • Number of reflux episodes
  • Characterization of reflux episodes
    • Physical properties (i.e., liquid, gas, mixed)
    • Chemical properties (i.e., acid or nonacid)
    • Height of the refluxate
    • Bolus presence and clearance
    • Acid presence and clearance
  • Relationship between symptoms and reflux episodes
  • Gastric belching and supragastric bleching

Pharyngeal manometry

  • Quantification of propulsive and resistive problems within the pharyngoesophageal segment and their respective possible relations.

Videofluoroscopic Swallow Study (VFSS)

  • Dynamic radiological technique
  • Evaluates signs of impaired efficacy and safety of swallowing

Hydrogen breath test

  • Diagnosis of small bowel bacterial overgrowth & carbohydrate malabsorption
  • Small bowel carbohydrate bacterial fermentation
  • Small bowel transit time

Saliva flow rate test

  • Xerostomia evaluation
  • Protocol :
    • Unstimulated salivary flow rate test
    • Stimulated salivary flow rate test (2% citric acid solution)
    • Report as mL/min

Anorectal manometry

  • Anal sphincter function
  • Anorectal sensation
  • Anorectal coordination during defecation
  • Anorectal reflexes

Balloon expulsion test

  • Bedside assessment of the ability to expel a simulated stool (warm water filled balloon)
  • Identify evacuation disorder

Antroduodenal manometry

  • Stomach & duodenal contraction
  • Small bowel neural function

Colonic manometry

  • Colonic motor function
  • Colonic motor response to stimuli (food, drugs) : provocation test

Rectal Barostat

  • Evaluation of rectal sensation & compliance
  • Diagnosis of defecatory disorder

Colonic transit study

  • Radioopaque markers test
  • Colonic transit time

Timed Barium Esophagogram

  • Assess the esophageal emptying
  • Initial evaluation of motor dysphagia, commonly caused by achalasia
  • Measure height and width of the barium column between 1,2, and 5 minutes

Esophageal Transit Scintigraphy

  • Measure esophageal transit time
  • Measure the time required for a liquid bolus of 15–30 mL of water containing 3.7–11 MBq (0.1–0.3 mCi) of either 99mTc diethylenetriaminepentaacetic acid or 99mTc-sulfur colloid to transit the esophagus after a single swallow
  • Measure esophageal retention at 10 min

Gastric scintigraphy

  • Evaluate gastric emptying
  • Ingestion of a test standard meal (typically >200 kcal) labeled with a radioactive isotope (99mTc for solids and 111 Indium for liquids)
  • Measurement of the percentage of gastric emptying after one, two, and four hours after ingestion.

Barium Defecography

  • Anorectal coordination during defecation
  • Demonstration of anatomical abnormality of pelvic floors
  • Anal sphincter anatomy and function

MRI Defecography

  • Anorectal coordination during defecation
  • Demonstration of anatomical abnormality of pelvic floors
  • Anal sphincter anatomy and function
