Laparoscopic radical antegrade modular pancreatosplenectomy: preliminary experience with 10 cases

Background The radical antegrade modular pancreatosplenectomy (RAMPS) which is a reasonable surgical approach for left-sided pancreatic cancer is emphasis on the complete resection of regional lymph nodes and tumor-free margin resection. Laparoscopic radical antegrade modular pancreatosplenectomy (LRAMPS) has been rarely performed, with only 49 cases indexed on PubMed. In this study, we present our experience of LRAMPS. Methods From December 2018 to February 2020, 10 patients underwent LRAMPS for pancreatic cancer at our department. The data of the patient demographics, intraoperative variables, postoperative hospital stay, morbidity, mortality, pathologic findings and follow-up were collected. Results LRAMPS was performed successfully in all the patients. The median operative time was 235 min (range 212-270 min), with an EBL of 120 ml (range 100-200 ml). Postoperative complications occurred in 5 (50.0%) patients. Three patients developed a grade B pancreatic fistula. There was no postoperative 30-day mortality and reoperation. The median postoperative hospital stay was 14 days (range 9-24 days).The median count of retrieved lymph nodes was 15 (range 13-21), and four patients (40%) had malignant-positive lymph nodes. All cases achieved a negative tangential margin and R0 resection. Median follow-up time was 11 months (range 3-14 m). Two patients developed disease recurrence (pancreatic bed recurrence and liver metastasis) 9 months, 10 months after surgery, respectively. Others survived without tumor recurrence or metastasis. Conclusions LRAMPS is technically safe and feasible procedure in well-selected patients with pancreatic cancer in the distal pancreas. The oncologically outcomes need to be further validated based on additional large-volume studies.
