Stepwise implementation of laparoscopic pancreatic surgery. Case series of a single centre's experience.

BACKGROUND

Laparoscopic pancreatic surgery still represents a challenge for surgeons. However, in recent decades the experience is expanding. Recent systematic reviews and meta-analyses confirm that laparoscopic pancreatic resection (LPR) is safe, feasible and worthwhile. This study analyses the first 100 consecutive LPRs in our centre.

METHODS

A retrospective analysis was conducted of the first 100 LPRs in a single supra-regional Belgian centre, performed between January 2012 and January 2019. Pre-, peri- and postoperative data were retrieved from a prospectively maintained database. All procedures were performed laparoscopically by two attending surgeons, specialized in minimally invasive and hepatopancreatobiliary surgery.

RESULTS

Of 100 procedures, 62 laparoscopic pancreatoduodenectomies (LPD) and 36 laparoscopic distal pancreatectomies (LDP) were performed, along with 1 enucleation and 1 central pancreatectomy. Indication was malignancy in 70%. Conversion rate was 24,2% in LPD and 11% in LDP. Median operative time was 330 min (IQR 300-360) in LPD and 150 min (IQR 142.5-210) in LDP. Median blood loss was 200 mL (IQR 100-487.5) in LPD and 150 mL (IQR 50-500) in LDP, transfusion rate was 22.6% and 8.3% respectively. Median length of stay (LOS) was 13 days (IQR 10-19.25) in LPD and 9 days (IQR 9-14) in LDP. R0 resection rate was 88.6% (62/70). Major complication rate (Clavien-Dindo grade III-IV) was 12%. Thirty-day mortality was 0%, 90-day mortality was 2%.

CONCLUSION

Our results confirm that LPR is a feasible and safe alternative to open pancreatic surgery. Safe implementation with a clear strategy is fundamental to gain experience and overcome the learning curve of this technically demanding procedures.
