Our office has created a new video describing what a patient goes through when they undergo esophageal manometry as well as 24 hour multi-channel pH and impedance testing.
This test is often ordered when a patient is suspected to be suffering from reflux, whether acid or non-acid, or is possibly suffering from abnormal muscle activity of the esophagus.
Symptoms that a patient may experience that may lead to such testing include: Read more »

H. pylori dominated the GI news in the 1990s, and despite it disappearing from the front pages, it remains a common and important clinical problem. The dominant recommended initial treatment strategy has been a clarithromycin-based PPI triple therapy, with either amoxicillin or metronidazole as the third drug. This approach was based on clinical studies, ease of use, and tolerability factors. Bismuth-based quadruple therapy (a bismuth agent, metronidazole, tetracycline, and a PPI), despite demonstrating excellent activity, was usually relegated to second-line therapy because of the complexity of the dosing as well as compliance and tolerability issues.
However, duringthe last decade, the widespread use of macrolides in the general population has led to rising resistance to clarithromycin (by 30% or more of H. pylori strains in some areas), and when clarithromycin resistance is present, the efficacy of clarithromycin-containing triple therapy falls from about 80% to 50% or even lower. However, clarithromycin resistance does not affect the efficacy of bismuth-based quadruple therapy, and that efficacy of those regimens remains at about 90% when patients are compliant with the treatment.
So the questions for you to consider are:
1) Do you know what the clarithromycin resistance rate in H. pylori is in your community?
2) What first-line H. pylori treatment regimen do you use?
3) Are you planning to change your H. pylori treatment strategy now that clarithromycin resistance rates are rising?
Let us know what you think.

It was sometime in the mid-nineties that parents started showing up in my office with reams of paper. Inkjet printouts of independently unearthed information pulled from AltaVista and Excite. Google didn’t exist. In the earliest days of the Web, information was occasionally leveraged by families as a type of newfound control.
A young father and his inkjet printer
One case sticks clearly in my mind. It was that of a toddler with medically unresponsive acid reflux and chronic lung disease. After following the child for some time, the discussion with the family finally moved to the option of a fundoplication (anti-reflux surgery). On a follow-up visit the father had done his diligence and appeared in the office with a banker box brimming with printed information. He had done his homework and his volume of paper was a credible show of force.
At the time in Houston, the Nissen and Thal fundoplication were the accepted fundoplication procedures in children. Deep from the bottom of one of the boxes, the father produced a freshly-reported method of fundoplication from Germany. He had compared the potential complications with other types of fundoplication and this was the procedure he wanted.
What he didn’t understand was that an experimental technique used on a limited numbers of adults didn’t necessarily represent the best option for his toddler. I gave it everything I had but didn’t get very far. The tenor of his argument was slightly antagonistic. Ultimately there was nothing more I could do. I deferred the remainder of the discussion to one of our best “talking” surgeons, but knew the father wouldn’t get the time and consideration that I had offered.
I never saw the child again. As they say, the father voted with his feet. Read more »
