Article Synopsis
  • * The study reviewed 19 patients, predominantly experiencing hypoglycemia, with tumor locations identified in 74% of cases via CT and 88% via intraoperative ultrasound, and the most common surgical procedure was enucleation (53%).
  • * The findings suggest that accurately locating insulinomas is vital for the right surgical approach, with enucleation recommended for suitable patients due to its higher success rates and lower serious morbidity, despite a higher occurrence of pancreatic fistulas.

Article Synopsis
  • - This study evaluated the effectiveness and safety of endoscopic management for patients with walled-off necrosis, examining cases from February 2019 to December 2023.
  • - Out of 11 patients, endoscopic management had a high technical success rate (90.9%), but only a 36.3% clinical success rate without additional interventions for larger or multi-lobulated cases.
  • - Combining endoscopic management with percutaneous intervention led to successful outcomes in all cases where earlier attempts failed, demonstrating a preferable, less invasive treatment strategy while reducing the need for surgical procedures.

Synchronous primary neoplasms of Meckel's diverticulum and colon malignancies are rarely reported in the literature. We present three patients with synchronous primary neoplasms of Meckel's diverticulum and colon malignancies. All tumors located in Meckel's diverticulum were incidentally found at laparotomy and the definitive diagnosis was made with microscopic examination of surgical specimens.

Background: Many imaging methods such as ultrasonography, computed tomography (CT), magnetic resonance imaging, and endoscopy are used to identify the problems or complications that occur in the perioperative period and to determine the appropriate therapeutic approach. Specialists at surgical clinics and intensive care units sometimes need diagnostic procedures that can give quick results or reveal unexpected results. In particular, rapid on-site evaluation of patients followed under intensive care conditions has several advantages.
