5 Strategies for Screening Barretts Esophagus

The commonly used procedure for screening and surveillance of Barretts esophagus is standard Esophagogastroduodenoscopy with biopsies per the Seattle Protocol. Surveillance periods differ depending on the degree of dysplasia limited to patients with Barrett’s oesophagus and confirmed dysplasia with endoscopic eradication therapy. Barrett oesophagus (BE) is a pre-malignant condition defined by conversion into the metaplastic columnar epithelium of the normal oesophagal squamous epithelium.

Nevertheless, a consensus has not yet been established on the specific criteria for the diagnosis. Most BE cases are acquired, with chronic gastroesophageal reflux (GERD) being the precipitant. Rare families have an increased risk of developing BE via the autosomal dominant inheritance of certain susceptibility alleles, known as the family Barrett phenotype oesophagus. BE predisposes patients for dysplasia and oesophagal adenocarcinoma (EAC), cancer with high morbidity and mortality, to grow. Surveillance systems, focused on the occurrence of non-dysplastic Barrett’s Esophagus, low-grade dysplasia, high-grade dysplasia, or invasive adenocarcinoma, have been developed to help management decisions. As new experiments and new research are analyzed and used in updated recommendations, these tend to change.

Another subject, which has undergone recent change, is when to apply various endoscopic and surgical therapies. Advances in technology and further patient risk stratification studies are research areas of focus with the potential to influence future recommendations for the diagnosis and management of Barretts Esophagus. Barretts Esophagus’ screening justification is early detection of patients at elevated risk of developing EAC, and prompt intervention to reduce mortality. Given a lack of randomized controlled trials (RCTs), indirect evidence indicates that screening leads to earlier stage identification of EAC, better results and 5-year survival rates increase.

The latest screening methods are ineffective as more patients diagnosed with EAC have no prior diagnosis of Barretts Esophagus and patients with EAC have no prior symptoms of gastroesophageal reflux disorder (GERD). Numerous modern screening methods for Barrett’s oesophagus, such as unsedated transnasal endoscopy, trefoil factor-3 cytospin and balloon cytology, oesophagal capsule endoscopy, liquid biopsyare available here.  Also, advanced imaging strategies such as narrow-band imaging, colour-based chromoendoscopy, confocal laser endomicroscopy, thermal laser endomicroscopy, and computer-assisted, 3-dimensional analysis of wide-area transepithelial sampling designed to help detect dysplasia are also investigated.

The 5 Strategies for screening Barretts Esophagus are listed below:

  1. Using Seattle protocol and biopsy of any mucosal defects in salmon-coloured mucosa above the GEJ, thorough visual examination during EGD and four-quadrant biopsies at every 1–2 cm interval is the gold standard procedure for Barretts Esophagus screening. There was also an assessment of normal brush cytology for Barretts Esophagus detection. Cytology has a high diagnostic precision for high-grade dysplasia, moderate sensitivity to Barretts Esophagus and poor sensitivity compared to histology for poor-grade dysplasia. Adding brush cytology supplements histology and raises the expense of diagnostic yield without change.
  2. Normal sEGD is expensive and associated with a slight risk of complications such as cardiopulmonary attacks, vomiting, leakage, perforation and indirect costs associated with patients. SEGD is therefore not a reasonable tool for screening huge populations, and it needs an alternative, inexpensive, widely accessible and reliable screening process.
  3. Unseated transnasal endoscopy (uTNE) is conducted to use an ultra thin endoscope utilizing topical anaesthesia to reduce the need for sedation. uTNE vulnerability to columnar lined oesophagus and IM recognition, as opposed to sEGD. The functional time varied from 3.7 ± 1.8 to 5.5 ± 1.7 min, and the average recovery period was faster in uTNE than in sEGD.
  4. Compared to sEGD, uTNE was better with less complication linked to treatment and sedation and high acceptability with the willingness to undergo repeat procedures. Slight complications involved mild suffocation, gagging, vomiting, nasal pain, sore throat and slight epitasis. No major adverse effects have been identified. For an RCT, the mean cost differences for sEGD and hospital-based uTNE vary. However, endoscopes with removable sheaths such as EndoSheath technology minimize costs by reducing the need for disinfection, and non-physicist professionals may be qualified to do the operation. Better acceptance and affordability allow for uTNE to be considered as a BE screening test for patients.
  5. Cytosponge is a mesh encircled by a gelatine capsule connected to a transorally passing line. The capsule melts in the proximal abdomen five minutes after swallowing, increasing the mesh to a 3 cm sphere. The cytological specimen sample is stained with Trefoil Factor 3, which is a biomarker for IM.

It is clear that by reading the above-mentioned information carefully one can easily be aware of the Barretts esophagus , which is very useful for everyone to the diagnosis of mortality from oesophageal adenocarcinoma along with its reduction also. Further, this information also emphasizes the most effective strategies of screening Barretts Esophagus. One can also contact the Refluxmd.com to gain more details regarding the same and some other essential facts related to a healthy life.
