/Aims: The aim of this study was to compare the diagnostic capabilities of narrow band imaging (NBI) colonoscopy with and without optical magnification in differentiating neoplastic from nonneoplastic colorectal polyps.
Between April 2012 and March 2013, 122 patients with colorectal polyps detected by using diagnostic conventional colonoscopy were prospectively enrolled. A total of 236 polyps were evaluated with NBI, in vivo in real time during therapeutic colonoscopy, by one experienced endoscopist. Whether magnification was used or not was determined by randomization. After an in vivo real-time endoscopic prediction of histology, all lesions were endoscopically excised. Surgical pathologic reports were used as the criterion standards. The sensitivity (Sn), specificity (Sp), positive predictive value (PPV), and negative predictive value (NPV) of identifying neoplastic polyps were calculated.
A total of 236 lesions with an average size of 5.6 mm in 122 patients were assessed (159 neoplastic, 77 nonneoplastic). The Sn, Sp, PPV, and NPV in differentiating neoplastic from nonneoplastic lesions with the magnified NBI were 97.5%, 83.3%, 94.0%, and 92.6%, respectively, whereas those of the nonmagnified NBI group were 97.5%, 85.1%, 91.7%, and 95.2%, respectively.
Nonmagnified NBI colonoscopy distinguishes neoplastic from nonneoplastic colorectal polyps as accurately as does magnified NBI colonoscopy.

AbstractAbstract PDFPubReaderePub

Eradication of Helicobacter pylori is widely accepted as initial therapy for low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, approximately 20% of patients with this disease are not responsive to H. pylori eradication therapy. The aim of this study was to assess remission and relapse rates of low-grade gastric MALT lymphoma after H. pylori eradication and identify the clinical factors that affect remission.


Thirty-nine patients diagnosed with gastric MALT lymphoma (May 2003 to May 2010) were retrospectively analyzed.


Of the 39 patients, 30 (77%) had a H. pylori infection. There were 35/39 (90%) patients with stage I. Among stage I, 25 patients with the infection underwent eradication therapy and 22/25 (88%) achieved remission. The total regression rate with eradication only in stage I was 24/28 (86%). The median time to remission was 98 days (range, 22 to 397 days). Age, tumor location, invasion depth, H. pylori burden, and severity of mononuclear leukocyte and neutrophil infiltration were not related to remission. However, patients with less neutrophil infiltration were more likely to achieve a successful first H. pylori eradication (p=0.049).


The results show that the rate of low-grade gastric MALT lymphoma regression (86%) with H. pylori eradication alone was higher than that in Western studies (77.8%) and that neutrophil infiltration was inversely related to success of the first H. pylori eradication procedure.
