A 65-year-old male patient was admitted to our hospital with continuous left hypochondralgia. CT scanning revealed an avascular tumor at the tail of the pancreas measuring 53 x 52 x 50 mm. Preoperative serum CEA was 198 ng/ml. During laparotomy, the tumor was deemed unresectable and insertion of a catheter in the splenic artery was carried out for postoperative arterial chemotherapy. Gemcitabine (GEM) was administered 1,000 mg 3 times in 2 months via the subcutaneous port connected to the catheter. Slight nausea was the only adverse effect. Decrease in tumor size was observed and serum CEA level dropped to 16.7 ng/ml. In the outpatient setting, 500 mg of GEM was administered several times. One year has passed since the initial treatment, and while the tumor is slowly enlarging, no liver metastasis has been observed. Oral NSAID has controlled the persisting back pain. In conclusion, arterial chemotherapy using GEM for advanced pancreatic cancer may be beneficial for patients.

Background/objectives: The aim was to investigate the association between variations in the dorsal pancreatic artery (DPA) and intrapancreatic arcade anatomy with Whipple procedure outcomes and postoperative complications.
Methods: This retrospective study was conducted with 362 patients who underwent a Whipple procedure at the Department of Gastroenterological Surgery of Adana City Training and Research Hospital between January 2018 and April 2024. All data collected from medical records were compared and statistically analyzed according to the patients' survival status and arcade subtypes.

Post-stroke early activation of neutrophils contributes to intensive neuroinflammation and worsens disease outcomes. Other pre-existing patient conditions can modify the extent of their activation during disease, especially hypercholesterolemia. However, whether and how increased circulating cholesterol amounts can change neutrophil activation responses very early after stroke has not been studied.
