Approach Considerations, Barrett Esophagus Screening and Surveillance, Ablative Therapy for Barrett Esophagus. The goal of ablative therapy is to destroy the Barrett epithelium to a sufficient depth to eliminate the intestinal metaplasia and allow regrowth of squamous epithelium. A number of modalities have been tried, usually in combination with medical or surgical therapy because successful ablation appears to require an antacid environment. Human studies have been performed with radiofrequency ablation (RFA), photodynamic therapy (PDT), argon plasma coagulation (APC), multipolar electrocoagulation (MPEC), heater probes, various forms of lasers, endoscopic mucosal resection (EMR), and cryotherapy. Ablative therapy is emerging as a viable alternative to surgical resection or esophagectomy for patients with high- grade dysplasia in Barrett esophagus. In fact, in most major medical centers ablation is first- line therapy. A study by Prasad found that the 5- year survival rate for patients with high- grade dysplasia in Barrett esophagus who were treated with PDT and EMR was comparable to that of patients treated with esophagectomy. It is also a treatment option for low- grade dysplasia in Barrett esophgus, provided the risks and benefits are thoroughly discussed with the patient. This technique requires the use of sizing balloons to determine the inner diameter of the targeted portion of the esophagus. Irritable Bowel Syndrome. The following information comes from The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), a part of the National. Discover natural cures to treat Barrett's Esophagus (Barrett's Syndrome), a digestive ailment related to GERD that can cause esophageal spasm and lead to cancer. Bloating or fullness, Nausea or vomiting, Stomach cramps and Upset stomach. WebMD Symptom Checker helps you find the most common medical conditions indicated by the. Peptic Ulcer Disease. Peptic ulcer disease (PUD) is a very common ailment, affecting one out of eight persons in the United States. The causes of PUD have gradually. ![]() This is followed by placement of a balloon- based electrode with a 3- cm long treatment area that incorporates tightly spaced, bipolar electrodes that alternate in polarity. The electrode is then attached to a radiofrequency generator and a preselected amount of energy is delivered in less than 1 second at 3. W. Shaheen et al demonstrated that RFA was associated with a high rate of complete eradication of dysplasia and intestinal metaplasia and a reduced risk of disease progression in patients with dysplastic Barrett esophagus. Among patients with high- grade dysplasia, complete eradication occurred in 8. Patients in the ablation group had less disease progression than did those in the control group (3. In a randomized study of 1. Barrett esophagus and low- grade dysplasia, Phoa et al found that in comparison with endoscopic surveillance, endoscopic radiofrequency ablation (RFA) significantly reduced the rate of neoplastic progression to high- grade dysplasia or adenocarcinoma. Typically, a hematoporphyrin is used as the photosensitizing agent because it has a greater affinity for neoplastic tissue. Another agent, 5- aminolevulinic acid (ALA), which induces endogenous protoporphyrin IX and has selectivity for the mucosa over deeper submucosal layers, has also been used. The results have been promising for the regression of Barrett esophagus, as well as for the treatment of dysplasia and superficial carcinoma. Using PTD to treat 1. Overholt et al found that Barrett mucosa was completely eliminated in 4. ![]() Do you have any of the following symptoms? Bloating, gas, belching, reflux, heartburn, burning in the stomach, constipation, or a heavy feeling in the stomach after.Additionally, PDT is an expensive and time- consuming endeavor, and early use was complicated by esophageal stricture requiring dilation in 5. PDT has been largely replaced by RFA in most medical centers performing ablation. APC ablation. APC is a method of contact- free high- frequency current coagulation in which the burning of tissue stops as soon as the area is ablated. One study using high- power APC was reported to result in complete restoration of squamous mucosa in 3. The major complications were chest pain and odynophagia, which occurred in 5. Only 3 patients experienced stricture, which was treated easily with dilation. Only 1 endoscopic, as well as histologic, recurrence was observed at 1. Continued How Is Barrett's Esophagus Diagnosed? Because there are often no specific symptoms associated with Barrett's esophagus, it can only be diagnosed with an. ![]() Nissen fundoplication. Other studies have been less encouraging, with persistence of residual foci of Barrett epithelium under the neosquamous lining in 2. MPEC ablation. MPEC is a method in which the mucosa is ablated by direct contact with an electrocautery probe. Sampliner et al used this technique to treat 1. LSBE, using half of the patient's own esophagus as an internal control, and found that all 1. Treatment took an average of 2. No adenocarcinoma or high- grade dysplasia of the esophagus developed in any of the patients. These results indicated the long- term efficacy and safety of mucosal ablation in Barrett esophagus. Laser ablation. Lasers have been used in numerous small studies for eradication of Barrett esophagus. Results were less consistent with this modality than with those listed above. Studies that demonstrated full or partial regression endoscopically were confounded by the persistence of glandular elements beneath the neosquamous epithelium in as many as one third of cases. Cryoablation. One of the newer ablative techniques is low- pressure cryospray ablation using liquid nitrogen, pioneered at the author's institution. The components of the low- pressure spray cryoablation device are as follows: Liquid nitrogen tank. Electronic console - For monitoring and controlling cryogen release. Dual foot pedal - For controlling cryogen release and heating of the catheter. Catheter - A multilayered, 7- 9. F, open- tipped catheter for spray of supercold nitrogen gas through an upper endoscope. The mechanism of injury is unique relative to other ablative techniques. Cryoablation induces apoptosis, causes cryonecrosis at supercold temperatures (- 7. The Barrett epithelium is resistant to apoptosis and, therefore, may be uniquely suited for treatment by cryoablation. A pilot study at the author's institution using cryoablation in Barrett esophagus with degrees of dysplasia ranging from no dysplasia to multifocal, high- grade dysplasia achieved complete endoscopic reversal of Barrett esophagus in 7. SIM or dysplasia at 6- month follow- up. These results will need confirmation at other institutions.
