Abstract
Laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS) has not been widely performed due to its technical challenging. We introduce a novel approach, named "Plane first" approach, for L-RAMPS in this study. From January 2015 to August 2021, we performed 51 cases of L-RAMPS. Patients were divided into two groups basing on the surgical approach: conventional approach (group 1) and "Plane first" approach (group 2). Data were retrospectively collected in terms of demographic characteristics, intra-operative variables, post-operative variables, and follow-up outcomes. The age, sex, BMI, and tumor size were comparable between two groups. Two patients in the group 1 required converting to open surgery. The patients in the group 2 required fewer operative time (210.5 ± 65.5min vs. 252.4 ± 24.7min, p < 0.01). They also suffered from less blood loss (136.0 ± 100.0ml vs. 158.8 ± 137.0ml, p = 0.15). The overall complications for patients in two groups were comparable. In terms of oncological outcomes, posterior margin was positive in two patients (10.5%) in the group 1. One patient (3.1%) in the group 2 had positive pancreatic neck margin. The number of lymph nodes harvested and overall survival between the two groups were comparable. "Plane first" approach RAMPS for patients with pancreatic adenocarcinoma in the left pancreas is safe and feasible, even in patients with PV/SMV involvement.
