As physicians, we have grown accustomed to the concept of screening for and surveillance of those found to have premalignant conditions with the expectation that by doing so we can prevent cancer and do little if any harm. In reality this concept has rarely been demonstrated to be true and indeed we often do great […]
Roughly one-fifth of all human cancers arise in the gastrointestinal tract. Worldwide, over 3.5 million patients are newly diagnosed with GI tract cancer each year, of whom 310,000 are in the U.S. alone. These malignancies show marked gender, racial and socioeconomic differences in incidence. For instance, esophageal and gastric adenocarcinomas occur more frequently in U.S. […]
Most Crohn’s disease patients who undergo an intestinal resection will have postoperative recurrence. The most effective way to prevent recurrence is to initiate an anti-TNF within four weeks of surgery. It has been my practice that patients at high risk for postoperative Crohn’s disease recurrence initiate anti-TNF shortly after they are discharged from the hospital. […]
A surgical resection for a patient with Crohn’s disease is a major milestone in the natural history of their condition. It is without a doubt that patients who require surgery will make avoiding further surgery a priority and accordingly many patients will consider any possible preventive measure. I explain to patients that surgery is usually […]
Gastroesophageal reflux disease (GERD) testing has evolved ever since the initial introduction of the catheter-based pH test more than half a century ago. More accurate pH measurements and improved patient tolerability were achieved by reducing the catheter’s diameter and stiffness, and the catheter-based pH test has continued to improve over the years.1 Introduction of the […]
Prolonged pH or reflux monitoring is neither essential to the primary evaluation or treatment of patients with suspected gastroesophageal reflux disease (GERD) who respond to therapy nor needed for patients who have endoscopydocumented erosive esophagitis that responds to antisecretory therapy. The history, endoscopic findings and clinical response to therapy provide adequate support for the diagnosis of GERD in […]
As a card-carrying gastroenterologist, I enjoy performing screening colonoscopy just like most of my society brethren. However, I feel strongly that the fecal immunochemical test (FIT) is a fully acceptable alternative for colorectal cancer (CRC) screening. Perhaps the easiest defense for those of us who are enthusiastic about stool-based screening is the quality of evidence supporting it. […]
In Australia and some European countries, colorectal cancer (CRC) screening occurs in an organized or programmatic setting, usually funded by the national government. Organized screening commonly relies on fecal occult blood testing (FOBT) as the primary means of screening, and usually the fecal immunochemical test (FIT). FIT is a good option for these programs as […]
F or patients found to have low-grade dysplasia (LGD) in Barrett’s esophagus, two recent studies suggest that the decision between treating with radiofrequency ablation (RFA) or simply continuing endoscopic surveillance is a slam dunk for RFA.1,2 In a European, randomized trial of surveillance versus radio frequency ablation (SURF) for 136 patients who had LGD confirmed […]
The primary goal of ablation in Barrett’s esophagus is to reduce progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC). The decision to perform endoscopic therapy (with the goal to eliminate intestinal metaplasia), is based on the principles of: 1. documenting an elevated risk of progression, 2. demonstrating reduction in risk of progression using robust […]
