Abstract
Purpose
Technical challenges and a perceived higher risk of complications hinder a wide adoption of minimally invasive pancreatoduodenectomy. We aim to further define the place of minimally invasive pancreatoduodenectomy by comparison with the traditional open approach.
Methods
A comparison of the surgical outcomes and survival after laparoscopic (LPD) versus open pancreatoduodenectomy (OPD) was retrospectively performed from a prospectively kept database. To reduce the effect of bias and confounding, baseline characteristics of both groups were matched using propensity score matching (NCT05110573; Nov 8, 2021; retrospectively registered).
Results
From a total of 67 LPD and 105 OPD patients, propensity score matching resulted in two balanced groups of 38 patients. In both groups, 87% of surgeries were performed for cancer. In the LPD group, conversion rate was 22.4%. Mean operative time was significantly longer after LPD versus OPD (320.1 ± 53.8 vs. 277.7 ± 63.8 min; p = .008). Hospital stay was significantly shorter after LPD versus OPD (median 13.5 vs. 17.0 days; p = .039). No significant differences were observed in blood loss, total complication rate (73.7% vs. 86.8%; p = .249), major complication rate (26.5% vs. 10.5%; p = .137), postoperative pancreatic fistula rate (13.2% vs. 7.9%; p = .711), 90-day mortality rate (5.3% vs. 0%; p = .493), R0 resection rate (85.4% vs. 85.8%), or number of lymph nodes (median 10.0 vs. 8.5; p = .273). In cancer patients, no significant differences were observed in overall survival (median 27.1 vs. 23.9 months; p = .693), disease-free survival, or recurrence rate.
Conclusion
LPD provided acceptable short-term and oncological outcomes. Compared to OPD, we noted a higher major complication rate, without compromising surgical safety or oncological outcomes.
