Article Synopsis
  • Gossypiboma is a rare surgical complication where gauze is unintentionally left inside the body, leading to inflammation and tissue adhesion, often without symptoms for years.
  • * It can be difficult to diagnose preoperatively, as common imaging techniques like ultrasound and CT may not clearly show it, especially when located near the gastrointestinal tract.
  • * The report highlights how endoscopic ultrasound and fine-needle aspiration can be effective for diagnosing gossypiboma before surgery by providing detailed imaging and tissue analysis.

An 83-year-old male underwent three transgastric punctures with endoscopic ultrasound-guided fine-needle aspiration for the examination of a pancreatic body tumor. After a diagnosis of resectable pancreatic cancer and undergoing distal pancreatectomy, the patient was administered postoperative adjuvant chemotherapy with oral S-1 for 6 months, and carcinoembryonic antigen and carbohydrate antigen 19-9 levels were bimonthly evaluated. Carbohydrate antigen 19-9 levels continually increased to 4638.

Aim: The purpose of this study was to clarify whether fatty pancreas might lead to impaired pancreatic endocrine or exocrine function.

Material And Methods: The study involved 109 participants who had undergone the glucagon stimulation test and N-benzoyl-L-tyros-p-amino benzoic acid (BT-PABA) test to assess pancreatic function as well as unenhanced abdominal computed tomography (CT). Pancreatic endocrine impairment was defined as ΔC peptide immunoreactivity less than 2 [mmol/L] in the glucagon stimulation test, and pancreatic exocrine impairment was defined as a urinary PABA excretion rate less than 70% on the BT-PABA test.

A woman in her 70s presented with dehydration and malnutrition due to watery diarrhea. She was examined and diagnosed with gastrointestinal amyloidosis accompanied by a protein-losing gastroenteropathy secondary to rheumatoid arthritis. She first underwent treatment with an anti-tumor necrosis factor alpha (TNF-α) antibody for secondary amyloidosis, but due to lack of adequate response, she was switched to an anti-interleukin (IL)-6 receptor antibody.

Background: Endoscopic resection (ER) has recently become standard treatment, even for early gastric cancer (EGC) in the remnant stomach. We aimed to compare long-term survival after ER versus radical surgery for EGC in the remnant stomach.

Methods: We retrospectively compared overall and cause-specific survival of patients who had undergone ER or radical surgery for EGC in the remnant stomach from 1998 to 2012.
