Background:
The method of transecting the pancreatic parenchyma during pancreatic resection may influence the rate of complications, including pancreatic fistula and bleeding. The objective of this study was to compare the transection of the pancreatic parenchyma during pancreatoduodenectomy with monopolar electrocautery versus scalpel in terms of postoperative complications.
Methods:
A retrospective analysis of patients with open pancreatoduodenectomy from the German DGAV StuDoQ|Pancreas registry (January 2013 to December 2021) was performed. Transection of the pancreatic parenchyma with a scalpel versus monopolar electrocautery was compared regarding postoperative pancreatic fistula B/C, post-pancreatectomy hemorrhage B/C, and major complications (Clavien-Dindo classification ≥3) rates. Multivariable analysis with adjustment for potential confounders and surgical center cluster effect was performed.
Results:
Overall, 6,752 patients were included in the study. In 4,072 (60.3%), transection was performed with a scalpel and, in 2,680 (39.7%), with electrocautery. Transection with electrocautery was associated with higher postoperative pancreatic fistula B/C (15.4% vs 12.8%; P = .003), post-pancreatectomy hemorrhage B/C (11% vs 7.4%; P < .001), and major complications (33.4% vs 29.6%; P = .001) rates. In the multivariable analysis, after adjustment for potential confounders and surgical center, the association of the transection method with postoperative pancreatic fistula B/C (odds ratio = 1.01; 95% CI, 0.79-1.2; P = .962), post-pancreatectomy hemorrhage B/C (odds ratio = 1.23; 95% CI, 0.94-1.6; P = .127), and major complications (odds ratio = 1.09; 95% CI, 0.93-1.27; P = .297) was not significant.
Conclusion:
The study found no significant association between transection of the pancreatic parenchyma during open pancreatoduodenectomy with a scalpel compared with monopolar electrocautery regarding pancreatic fistula, postoperative bleeding, or overall major complication rates.
