Robotic-assisted central pancreatectomy: A minimally invasive approach for benign and low-grade lesions.

Background: Centrally located pancreatic lesions are often treated with extended pancreaticoduodenectomy or distal pancreatectomy resulting in loss of healthy parenchyma and a high risk of diabetes and exocrine insufficiency. Robotic central pancreatectomy (RCP) is a parenchyma sparring alternative that has been shown safe and feasible [1,2].
Methods: In this article, we describe our operative technique and the perioperative outcomes of a series of RCP for low-grade or benign pancreatic tumors.
Results: Six patients (5 female and 1 man) with a median age of 51.5 (44-68) years underwent a RCP for 2 serous cystadenomas, 2 mucinous cystic tumors, 1 neuroendocrine tumor, and 1 autoimmune pancreatitis. There were no conversions, intraoperative complications, or perioperative transfusions. Median operative time and was 240 (230-291) minutes and median blood loss was 100 (100-400) ml. The median hospital stay was 8 (5-27) days. There were no mortalities, reoperations, or readmissions. One patient developed a grade B pancreatic fistula which was successfully managed conservatively. All resections had free margins and the median tumor size was 2.5 (1.5-3.5) cm. After a mean follow-up of 46 months, no patients presented new-onset diabetes or exocrine insufficiency.
Conclusions: RCP represents the least invasive option for both the patient and the pancreatic parenchyma. With a standardized technique, RCP results in low postoperative morbidity and excellent long-term pancreatic function. Although our results are excellent, POPF still represents the main complication of central pancreatectomy with an incidence ranging from 0 to 80% depending on multiple factors such as the surgeon, technique, and pancreatic texture.
