Optimal Bowel Preparation Method to Visualize the Distal Ileum via Small Bowel Capsule Endoscopy.

Small bowel capsule endoscopy (SBCE) is a convenient and minimally invasive method widely used to evaluate the small intestine. 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.

Correlation between hospital-onset and community-onset Clostridioides difficile infection incidence: Ward-level analysis following hospital relocation.

Background: The development of hospital-onset Clostridioides difficile infection (HO-CDI) is affected by patient and environmental risk factors. We investigated changes in the incidence of HO-CDI after relocation to a newly built hospital with 50% private rooms and evaluated the associated factors.

Methods: A retrospective study was conducted to assess trends in CDI incidences before and after the relocation using segmented regression analysis model.

Neuroendocrine tumor of the ampulla of Vater showing chronological endoscopic changes.

We report a rare case of neuroendocrine tumor of the ampulla of Vater in a 53-year-old Japanese male. The patient was admitted to our institution for workup of presyncope secondary to anemia. Medical history was pertinent for coronary artery disease, for which he had drug eluting stents (DES) placed and was on aspirin and clopidogrel therapy.

Pancreatic Colloid Carcinoma Presenting with Acute Pancreatitis.

Pancreatic colloid carcinoma, also known as mucinous non-cystic carcinoma, is a rare subtype of pancreatic cancer accounting for 1-3% of the pancreatic malignant neoplasms. We herein report a woman who initially presented for acute pancreatitis. Computed tomography showed pancreatic swelling due to acute pancreatitis and a 16-mm mass with an enhanced margin in the pancreatic tail.

A rare case of immunotherapy-induced cholangitis and gastritis.

Immune checkpoint inhibitor-related liver injury usually appears as a hepatitis pattern, with a cholangitis pattern being a rare immune-related adverse event. We report a Japanese man in his fifties with immune checkpoint inhibitor-induced cholangitis and gastritis. The patient had been treated for approximately 7 months with carboplatin, pemetrexed sodium hydrate, and bevacizumab for an undifferentiated cancer of unknown primary, with metastases to the right pleura and nasolacrimal duct.
