Background/aims: This study aimed to examine the synergistic effect of independent risk factors on post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP).
Methods: This multicenter retrospective study included 1,273 patients with native papillae who underwent ERCP for bile duct stones in Japan. Independent PEP risk factors were identified using univariate and multivariate analyses.
Article Synopsis
- * A study focused on 20 high-risk, unresectable CRLM patients treated with hepatectomy and optional local ablation; outcomes showed that all patients responded positively to chemotherapy, with low recurrence rates after surgery.
- * The findings indicate that the treatment approach for high-risk patients is effective, achieving a 3-year disease-free survival rate of 57.4% and a 5-year overall survival rate of 56.2%, regardless of whether local ablation was included.
The field-induced quantum-disordered state of layered honeycomb magnet α-RuCl is a prime candidate for Kitaev spin liquids hosting Majorana fermions and non-Abelian anyons. Recent observations of anomalous planar thermal Hall effect demonstrate a topological edge mode, but whether it originates from Majorana fermions or bosonic magnons remains controversial. Here, we distinguish these origins from combined low-temperature measurements of high-resolution specific heat and thermal Hall conductivity with rotating magnetic fields within the honeycomb plane.

However, especially in the distal ileum, visualization of the intestinal mucosa is frequently hampered by the remaining intestinal contents, making it difficult to detect critical lesions. Although several studies have reported on the efficacy of bowel preparation before SBCE, no standardized protocol has been established.

- Internal hernias, particularly those in the pararectal fossa, are rare and can lead to serious complications if not diagnosed quickly.
- An 87-year-old woman presented with lower abdominal pain and vomiting, which led to the discovery of a strangulated small bowel obstruction during surgery.
- The patient was successfully treated without bowel resection, highlighting the importance of considering rare internal hernias in undiagnosed intestinal obstruction cases.
