Totally Laparoscopic Pancreaticoduodenectomy: Comparison Between Early and Late Phase of an Initial Single-Center Learning Curve.

Despite recent advances in minimally invasive pancreatic surgery, laparoscopic pancreaticoduodenectomy (LPD) has not reach a wide diffusion, mainly due to its technical difficulty. Considering its potential benefits, efforts should be made to improve its adoption. Between January 2017 and March 2020, LPD was offered as the primary approach to all the patients with an indication to pancreaticoduodenectomy. The overall cohort was divided into two groups: the early group (EG), including the first 30 cases, and the late group (LG), with the remaining patients. Perioperative data were gathered from a prospectively collected database and retrospectively analyzed, comparing the short-term outcomes of the two groups. In the study period, 52 patients underwent LPD. Among these, 88.4% patients were preoperatively diagnosed with a malignant disease. No difference was found between EG and LG in terms of baseline characteristics, mean operative time, estimated blood loss, and conversion to laparotomy. The overall complication rate was 57.7%, with severe complications occurring in 14 patients (26.9%). Two patients (3.8%) deceased within 90 days from the operation. No difference was found between EG and LG regarding postoperative outcomes. Among oncological patients, 86.7% received an R0 resection, and 13.3% had an R1 resection. The EG and LG did not differ in terms of oncological radicality and number of lymph nodes retrieved. LPD is a reproducible surgical technique that may provide acceptable results in both early and late phase of experience, when performed by surgical team with broad background in laparoscopic surgery.
