Effects of Surgical Timing on Perioperative Clinical Outcomes in Pancreaticoduodenectomy

Influence of Timing on Outcomes of Pancreaticoduodenectomy: Complications, Hospital Costs, and Length of Stay

With the advancement of surgical techniques and the increase in pancreatic oncologic diseases, the volume of pancreaticoduodenal surgeries has been increasing year by year in our center, and multiple pancreaticoduodenal surgeries are often performed on the day of surgery. This study will compare the effect of pancreaticoduodenal surgery performed at different times on patient prognosis. This study plans to divide the patients into morning group, afternoon group, and night group through the start time of surgery, and this study plans to analyze subgroups such as laparoscopic pancreaticoduodenal surgery. The outcome indicators include perioperative complications such as pancreatic fistula, bleeding, abdominal infection, hospitalization cost, and length of hospital stay. The conclusions drawn from this study will suggest to surgeons whether pancreaticoduodenal surgery performed at different times of the day will have different outcomes for patients and will guide surgeons on the timing of pancreaticoduodenal surgery.
