Minimally invasive radical pancreatectomy for left-sided pancreatic cancer:Current status and future perspectives

Minimally invasive distal pancreatectomy with splenectomy has been regarded as a safe and effective treatment for benign and borderline malignant pancreatic lesions.However,its application for left-sided pancreatic cancer is still being debated.The clinical evidence for radical antegrade modular pancreatosplenectomy(RAMPS)-based minimally invasive approaches for leftsided pancreatic cancer was reviewed.Potential indications and surgical concepts for minimally invasive RAMPS were suggested.Despite the limited clinical evidence for minimally invasive distal pancreatectomy in left-sided pancreatic cancer,the currently available clinical evidence supports the use of laparoscopic distal pancreatectomy under oncologic principles in wellselected left sided pancreatic cancers.A pancreasconfined tumor with an intact fascia layer between the pancreas and left adrenal gland/kidney positioned more than 1 or 2 cm away from the celiac axis is thought to constitute a good condition for the use of margin-negative minimally invasive RAMPS.The use of minimally invasive(laparoscopic or robotic)anterior RAMPS is feasible and safe for margin-negative resection in wellselected left-sided pancreatic cancer.The oncologic feasibility of the procedure remains to be determined;however,the currently available interim results indicate that even oncologic outcomes will not be inferior to those of open radical distal pancreatosplenectomy.
