Impact of surgeon work duration prior to distal pancreatectomy on perioperative outcomes: a propensity score matching analysis

BACKGROUND: Surgeons are likely to get progressively fatigued during the course of a normal workday. The objective of this study was to evaluate the impact of surgeon work duration prior to performing distal pancreatectomy (DP) on the perioperative outcome, especially frequency of grade II or higher grade postoperative complications. METHODS: Patients undergoing DP for all causes were divided into two groups according to surgeon work hours prior to performing DP: group A (less than 5 h) and group B (5–10 h). Propensity score matching (PSM) analysis (1:1) were performed to balance the baseline characteristics between the two groups. Intraoperative complications were compared between the two groups. Postoperative complications and their severity were followed up for 60 days and mortality for 90 days. The study was powdered to identify a 15% difference in the incidence of grade II or higher grade complications. RESULTS: By using PSM analysis, the patients in group A (N = 202) and group B (N = 202) were well matched regarding demographics, comorbidities, operative technique, pancreatic texture and pathology. There was no significant difference in the incidence of grade II or higher grade complications between the two groups. There was no difference in clinically relevant postoperative pancreatic fistula, percutaneous drainage, readmission, reoperation, or morality. Group B was associated with a higher incidence of intraoperative organ injury, which could be managed successfully during the operation. CONCLUSION: The retrospective study demonstrated that the surgeon work duration did not significantly affect the clinical outcome of DP.
