A systematic scoping review of the initial experience with laparoscopic radical antegrade modular pancreatosplenectomy for pancreatic malignancy.

Background: Laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS) is a validated surgical approach for the surgical treatment of pancreatic malignancies of the body and tail of the pancreas. Open (O-) RAMPS is an established technique that offers oncological efficacy and acceptable post-operative outcomes when compared to standard distal pancreatectomy for pancreatic malignancies. This review aimed to determine the types of evidence available for L-RAMPS, and its selection criteria and reported outcomes, using systematic scoping review methodology. Methods: A systematic review of available literature was performed in September 2020. Data extracted included patient selection criteria, technical details, total number of L-RAMPS procedures performed, lymph nodes retrieved, resection margins, survival, LOS and complications. Results: Eight papers were eligible for inclusion, totalling 92 cases. There were no studies that directly compared O- to L-RAMPS. All reports were small retrospective cohorts with 3–30 patients. Selection criteria were reported in 4/8 studies and differed between studies. Technique descriptions were included in 6/8 studies. Studies reported a median of 5 (range 1–9) out of ten operative and clinical outcomes, including operative time median range 188–431 min, intraoperative blood loss median range 18–445 mL, R0 resection rate median range 91–100%, number of lymph nodes median range 11–43, and length of stay median range 12–20 days. Conclusions: L-RAMPS is infrequently reported in the literature. There are currently no data to allow for direct comparison of O- and L-RAMPS. Reports of L-RAMPS have an acceptable oncological and safety profile. A standardised description of the operative technique and outcome reporting, as well as specific training initiatives may be beneficial to broaden the application of L-RAMPS. [ABSTRACT FROM AUTHOR]
