This is a case of a 64-year-old patient with long standing reflux disease. At an upper endoscopy, a circumscribed early Barrett’s neoplasia was detected. Subsequent endosonography did not show any involvement of lymph nodes.

Here, an endoscopic resection of the Barrett’s neoplasia with a ligation device is performed. In this case, the final histological diagnosis of the specimen was a moderately differentiated neoplasia extending to the edge of the submucosa without any lymph vessel invasion. Therefore, the endoscopic resection is regarded to be curative in this case.

 

 

Take home messages:

 

  • Indeed, endoscopic resection is the treatment of choice for most early Barrett’s neoplasias that do not invade deeper than the upper layer of the submucosa.
  • Some neoplasias are very subtle and hard to demarcate and in these cases auxiliary techniques like chromoendoscopy are highly recommended, in particular chromoendoscopy with acetic acid as it highlights the mucosal details of both, the non-neoplastic and the neoplastic mucosa.
  • For prediction of local infiltration depth macroscopic evaluation is superior to endosonography.
  • However, before proceeding to endoscopic resection a complete staging of the tumor is mandatory. This certainly includes endosonographic evaluation of a possible lymph node involvement.

In this open-label study, adalimumab was effective for maintaining clinical remission in anti-tumor necrosis factor-naive patients with moderately to severely active ulcerative colitis who did not adequately respond to conventional therapy. Remission rate after 2 weeks treatment is about 30%, response rate about 50%.

When starting a patient on mesalamine for remission maintenance in ulcerative colitis, there is no difference in the long-term flare risk between low versus high average daily dose as long as the patients have a high to moderate level of adherence.

Oral budesonide (9 mg once daily) is effective and safe for short-term treatment of collagenous colitis, whereas short-term treatment with oral mesalamine (3 g once daily) appears to be ineffective.

An interferon-free 12-week regimen of ABT-450/r and ABT-072 with ribavirin was well tolerated in this pilot study and achieved high sustained viral response rate through 36 weeks of post-treatment observation.

This study suggest that sofosbuvir, an uridine nucleotide analogue selective inhibitor of hepatitis C virus (HCV) NS5B polymerase, is well tolerated and shows promising efficacy in a 12 weeks treatment period in patients with chronic hepatitis C virus genotype-1 infection, including those with cirrhosis.

Patients treated with MK-7009 (vaniprevir), a non-covalent competitive inhibitor of the hepatitis C virus (HCV) NS3/4A protease, plus peginterferon-α2a and ribavirin (P/R) experienced significant improvement in sustained viral response compared to P/R control in a population of HCV genotype 1 interferon-experienced patients.

Among patients with Barrett’s esophagus, approximately 2% will die of esophageal cancer within 10 years. However, patients with Barrett’s esophagus died more frequently of other causes, such as ischemic heart disease.

Single nucleotide polymorphisms in the ABO gene, predictive of ABO blood groups, are associated with risk of advanced precancerous gastric lesions in individuals infected with Helicobacter pylori, but the assessment of the risk is strictly dependent on cagA status.

Risk of Barrett’s esophagus increased linearly with earlier age at onset of frequent gastroesophageal reflux disease (GERD) symptoms. Age at symptom onset may help practitioners decide which patients with GERD symptoms to refer for endoscopic screening for Barrett’s esophagus.
