  • Characterization of Chronic Gastritis in Lynch Syndrome Patients With Gastric Adenocarcinoma

    Gastric cancer is one of the Lynch syndrome (LS)-associated malignancies. Previous studies have suggested that LS patients with gastric cancer also had chronic atrophic gastritis in the background mucosa, but further histologic characterization was not attempted.

  • Cirrhosis Is Associated With Worse Outcomes in Ischemic Colitis: A Nationwide Retrospective Study

    Ischemic colitis (IC) occurs when the blood supply of the large intestine becomes compromised. Cirrhosis is a disease entity in which there is a delicate balance between pro-coagulant and anti-coagulant states. Our aim was to examine the impact cirrhosis has on outcomes in patients with ischemic colitis.

    Colonic capsule endoscopy (CCE) derived from the video capsule endoscopy, initially proposed to explore the small bowel, has demonstrated high sensitivity and specificity for colonic polyp detection. The primary outcome of the study was to assess the safety, feasibility, and reliability of CCE after colorectal surgery.
