Pancreatic diseases often require surgery or invasive procedures to provide a chance for a cure. However, due to the pancreas's unique anatomical structure, its relative position to adjacent organs, and its dual endocrine and exocrine functions, the complexity of surgery is increased, impacting the patient's postoperative quality of life. Therefore, this project aims to retrospectively collect basic data, preoperative and postoperative blood tests (blood cell counts, biochemistry, tumor markers, glucose-related, lipid-related), and preoperative and postoperative imaging examinations (CT, MRI, Ultrasound, PET scan, Endoscopy, etc.) of patients who underwent pancreatic surgery at our hospital. We aim to compare whether surgical methods, lesion margin clearance rates, and postoperative remnant pancreatic volume affect the patient's endocrine function, exocrine function, quality of life, and disease prognosis. This analysis is intended to understand the indications, surgery-related factors, and prognosis for patients planning to undergo pancreatic surgery, with the expectation of providing more diverse and specific treatment recommendations for patients with pancreatic diseases in the future
