Abstract
Background
In our first experience, laparoscopic pancreatoduodenectomy (LPD) was associated with higher morbidity than open PD. Since, the surgical technique has been improved and LPD was avoided in some patients at very high risk of postoperative pancreatic fistula (POPF). We provide our most recent results.
Method
Between 2011 and 2018, 130 LPD were performed and divided into 3 consecutive periods based on CUSUM analysis and compared: first period (n = 43), second period (n = 43), and third period (n = 44).
Results
In the third period of this study, LPD was more frequently performed in women (46%, 39%, 59%, p = 0.21) on dilated Wirsung duct > 3 mm (40%, 44%, 57%; p = 0.54). Intraductal papillary mucinous neoplasm (IPMN) became the primary indication (12%, 39%, 34%; p = 0.037) compared to pancreatic adenocarcinoma (35%, 16%, 16%; p = 0.004). Malignant ampulloma re-increased during the third period (30%, 9%, 20%; p = 0.052) with the amelioration of surgical technique. The operative time increased during the second period and decreased during the third period (330, 345, 270; p < 0.001) with less blood loss (300, 200, 125; p < 0.001). All complications decreased, including POPF grades B/C (44%, 28%, 20%; p = 0.017), bleeding (28%, 21%, 14%; p = 0.26), Clavien-Dindo III–IV (40%, 33%, 16%; p = 0.013), re-interventions (19%, 14%, 9%; p = 0.43), and the hospital stay (26, 19, 18; p = 0.045). Less patients with similar-sized adenocarcinoma were operated during the second period (70%, 33%, 59%; p = 0.002) with more harvested lymph nodes in the third period (21,19, 25; p = 0.031) and higher R0 resection (70%, 79%, 84%; p = 0.5). On multivariate analysis the protective factors against POPF of grades B/C were pancreatic adenocarcinoma and invasive IPMN, BMI < 22.5 kg/m2, and patients operated in the third period.
Conclusion
This study showed that the outcome of LPD significantly improves with the learning curve and patient selection. For safe implementation and during the early learning period, LPD should be indicated in patients at lower risk of POPF.
