Résumé
A fatty infiltration of the pancreas has been traditionally regarded as the main histological risk factor for postoperative pancreatic fistula, whereas the role of the secreting acinar compartment has been poorly investigated. The aim of this study was to evaluate the role of acinar content at the pancreatic resection margin in the development of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis after pancreaticoduodenectomy. Data from 388 consecutive patients who underwent pancreaticoduodenectomy (2018-2019) were analyzed. Pancreatic section margins were histologically assessed for acinar, fibrosis, and fat content. Acinar content was categorized using median and third quartile as cut-offs. Univariate and multivariable analysis of possible predictors of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis were performed. Acinar content was <60% in 166 patients (42.8%), ≥60% and ≤80% in 156 patients (40.2%), and >80% in 66 patients (17.0%). The rate of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis was significantly higher in patients with acinar content >80% (39.4% and 33.3%, respectively) as well as in those with acinar content ≥60% and ≤80% (36.5% and 35.3%, respectively), compared with patients with acinar content <60% (10.2% and 5.4%, respectively) (P < .001). Acinar content was identified as an independent predictor of clinically relevant postoperative pancreatic fistula (≥60% and ≤80%, odds ratio 2.51, P = .008; >80%, odds ratio 2.93, P = .010) and clinically relevant postoperative acute pancreatitis (≥60% and ≤80%, odds ratio 9.42, P < .001; >80%, odds ratio 10.16, P < .001). An acinar content at the pancreatic resection margin ≥60% is associated to an increased risk of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis. Fat content was associated neither with clinically relevant postoperative pancreatic fistula nor with clinically relevant postoperative acute pancreatitis.

BACKGROUND
A fatty infiltration of the pancreas has been traditionally regarded as the main histological risk factor for postoperative pancreatic fistula, whereas the role of the secreting acinar compartment has been poorly investigated. The aim of this study was to evaluate the role of acinar content at the pancreatic resection margin in the development of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis after pancreaticoduodenectomy.
METHODS
Data from 388 consecutive patients who underwent pancreaticoduodenectomy (2018-2019) were analyzed. Pancreatic section margins were histologically assessed for acinar, fibrosis, and fat content. Acinar content was categorized using median and third quartile as cut-offs. Univariate and multivariable analysis of possible predictors of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis were performed.
RESULTS
Acinar content was <60% in 166 patients (42.8%), ≥60% and ≤80% in 156 patients (40.2%), and >80% in 66 patients (17.0%). The rate of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis was significantly higher in patients with acinar content >80% (39.4% and 33.3%, respectively) as well as in those with acinar content ≥60% and ≤80% (36.5% and 35.3%, respectively), compared with patients with acinar content <60% (10.2% and 5.4%, respectively) (P < .001). Acinar content was identified as an independent predictor of clinically relevant postoperative pancreatic fistula (≥60% and ≤80%, odds ratio 2.51, P = .008; >80%, odds ratio 2.93, P = .010) and clinically relevant postoperative acute pancreatitis (≥60% and ≤80%, odds ratio 9.42, P < .001; >80%, odds ratio 10.16, P < .001).
CONCLUSION
An acinar content at the pancreatic resection margin ≥60% is associated to an increased risk of clinically relevant postoperative pancreatic fistula and clinically relevant postoperative acute pancreatitis. Fat content was associated neither with clinically relevant postoperative pancreatic fistula nor with clinically relevant postoperative acute pancreatitis.
