BACKGROUND Various neoplasms, including neuroendocrine neoplasms (NENs), can arise from the presacral space. Most presacral lesions are detected due to symptoms arising from tumor growth. However, diagnosing small, asymptomatic presacral tumors is challenging because of their unique location.

- Sessile serrated lesions (SSLs) are potential precursors to colorectal cancer, and selectively removing them could decrease healthcare costs, yet distinguishing them from hyperplastic polyps (HPs) during colonoscopy is difficult.* -
- A multicenter study involved expert endoscopists using magnifying colonoscopy to differentiate SSLs from HPs, with findings showing a sensitivity of 79.8% overall and 82.4% for those diagnosed with high confidence.* -
- Despite the expertise involved, accurately diagnosing SSLs is challenging, leading to a recommendation that all JNET type 1 lesions that are 6 mm or larger should be removed to avoid missing a significant number of SSLs.*
Article Synopsis
- Accurate estimation of polyp size is crucial for determining treatment and monitoring intervals in colorectal care, yet many endoscopists make these estimations incorrectly without realizing it.
- A study involving 261 endoscopists in Japan assessed how experience influenced their ability to size polyps, revealing that those with fewer colonoscopy procedures performed in the past year were more likely to misjudge sizes.
- Results showed that inexperienced endoscopists tended to overestimate polyp sizes significantly more than their experienced counterparts, highlighting the need for better training and awareness in size estimation.
Article Synopsis
- This study explored the benefits of removing colorectal polyps immediately during the insertion phase of a colonoscopy, instead of waiting until the withdrawal phase.
- A randomized trial involved 220 patients with small left-sided polyps, comparing instant polypectomy to the traditional method, and found that the instant removal reduced overall procedure time significantly.
- Results showed that instant removal not only shortened the procedure but also prevented any missed polyps, suggesting it as a more efficient approach without negative impacts on the examination.
We report the first case of non-specific interstitial pneumonia (NSIP) in a patient with cancer-associated myositis (CAM) that emerged along with the recurrence of the cancer. A 60-year-old woman, with a history of partial gastrectomy for gastric cancer 11 years ago, presented with exertional dyspnea with anti-Jo-1 antibody-positive myositis. Surgical lung biopsy showed NSIP with metastatic gastric cancer.

Methods: Patients who received colonoscopy and polypectomy were recruited in the retrospective study. Probable histology of the polyps was predicted by six colonoscopists by the use of NICE classification.
Cytomegalovirus (CMV)-associated gastric ulcers can be found not only in immunocompromised hosts but also in normal individuals. The accurate endoscopic diagnosis of CMV ulcers is not easy because of the absence of characteristic morphological features. We present a case of CMV-associated gastric ulcer in an immunocompetent patient.

It has not been determined whether standard oral and intravenous administration of antibiotics have different prophylactic effects against post-TACE/TAI infection. We compared the efficacy of oral levofloxacin (LVFX) and intravenous cephazolin (CEZ) in patients receiving TACE/TAI for hepatocellular carcinoma (HCC) using a prospective design.
