Abstract
Background
Postoperative pancreatic fistulas (POPFs) are considered inevitable in some patients after pancreaticoduodenectomy (PD), and measures to minimize their clinical impact are needed. Postpancreatectomy hemorrhage (PPH) and intra-abdominal abscess (IAA) are the most severe POPF-related complications, and concomitant leakage of contaminated intestinal content is considered the main cause. An innovative method, modified non-duct-to-mucosa pancreaticojejunostomy (TPJ), was created to prevent concomitant leakage of intestinal content, and its effectiveness was compared between two periods.
Methods
All PD patients undergoing pancreaticojejunostomy from 2012 to 2021 were included. The TPJ group consisted of 529 patients recruited from January 2018 to December 2021. A total of 535 patients receiving the conventional method (CPJ) from January 2012 to June 2017 were used as a control group. PPH and POPF were defined according to the International Study Group of Pancreatic Surgery definition, but only PPH grade C was included for analysis. An IAA was defined as a collection of postoperative fluid managed by CT-guided drainage with documental culture.
Results
There were no significant differences in the rate of POPF between the two groups (46.0% vs. 44.8%; p = 0.700). Furthermore, the percentages of bile in the drainage fluid in the TPJ and CPJ groups were 2.3% and 9.2%, respectively (p < 0.001). Lower proportions of PPH (0.9% vs. 6.5%; p < 0.001) and IAA (5.7% vs. 10.8%; p < 0.001) were observed for TPJ than for CPJ. On adjusted models, TPJ was significantly associated with a lower rate of PPH (odds ratio [OR] 0.132, 95% confidence interval [CI] 0.051–0.343; p < 0.001) and IAA (OR 0.514, 95% CI 0.349–0.758; p = 0.001) than CPJ.
Conclusions
TPJ is feasible to be performed and is associated with a similar rate of POPF but a lower percentage of concomitant bile in the drainage fluid and subsequent rates of PPH and IAA than CPJ.
