Inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), in intestinal epithelial cells significantly contribute to inflammatory bowel disease (IBD) and colorectal cancer (CRC). Given our previous findings that TNF-α is upregulated in intestinal epithelial Caco-2 cells induced by skatole, a tryptophan-derived gut microbiota metabolite, the present study aimed to explore the relationship between skatole and IL-6, alongside TNF-α. Skatole elevated the promoter activity of IL-6 as well as TNF-α, and increased IL-6 mRNA expression and protein secretion.

Article Synopsis
  • ERCP is a medical procedure that can have some risks, including a condition called post-ERCP pancreatitis (PEP), which can happen when the procedure is tough to do.
  • A study with over 1,500 patients looked at whether doing an early cut (precut technique) helps lower the chances of getting PEP compared to a delayed cut.
  • The results showed that early precut patients had a lower risk of PEP (3.5%) compared to those who had a delayed cut (10.5%), and using a pancreatic stent during the delayed cut can help reduce PEP risk even more.

A 30-year-old man with idiopathic peptic ulcer disease (IPUD) experienced repeated recurrence of ulcerative bleeding despite treatment with lansoprazole and then vonoprazan. Further evaluation suggested that the cause of the ulcer was strong contractile movements of the antrum. This prompted the co-administration of trimebutine maleate (TM) and vonoprazan to relieve the stomach contractions.

Background And Aim: Percutaneous drainage of intra-abdominal abscesses is often uncomfortable for the patient and may result in prolonged hospital stays. Recent studies have shown that endoscopic ultrasound-guided abscess drainage (EUS-AD) could effectively treat various abscesses and fluid collections. However, no indications or procedures have been established for EUS-AD treatments, and studies on its usefulness and safety are insufficient.

Increased tumor necrosis factor α (TNFα) expression in intestinal epithelial cells (IECs) plays a major role in the development and progression of inflammatory bowel disease (IBD) and colorectal cancer (CRC). The present study aimed to clarify the relationship between TNFα and skatole, a tryptophan-derived gut microbiota metabolite. The aryl hydrocarbon receptor (AhR) antagonist CH223191 promoted, whereas the p38 inhibitor SB203580 suppressed the increase in TNFα mRNA and protein expression induced by skatole in intestinal epithelial Caco-2 cells.

We present a 56-year-old female patient diagnosed with stage 2/grade 3 non-alcoholic steatohepatitis (NASH) via liver biopsy. Over the next 14 years, six liver biopsies were performed, and the patient was followed up clinically. This was a valuable case wherein we were able to investigate the histology of the liver and the timing of changes in the AST/ALT ratio, platelets, albumin, FIB4-Index, and liver fibrosis markers.

  • A 72-year-old woman undergoing treatment for pancreatic cancer came to the hospital for a routine check-up and showed no abdominal symptoms.
  • Blood tests indicated elevated inflammation markers, and imaging studies suggested issues with her gallbladder, though a clear diagnosis was not initially reached.
  • Further ultrasound revealed signs of gangrenous cholecystitis, leading to surgical removal of the gallbladder, which confirmed severe tissue damage through pathology.

Afferent-loop syndrome (ALS) is known as a rare complication of partial or total gastrectomy and also occurs after pancreatoduodenectomy. The symptoms of ALS vary with the location of the mechanical obstruction, and the choice of therapeutic method should reflect the patient's condition and disease state. Herein, we report the use of endoscopic ultrasound (EUS)-guided afferent loop drainage with a plastic stent and its reintervention for malignant ALS.
