Recently, there have been several reports on minimally-invasive surgery for extended pancreatectomy (MIEP) in the literature. However, to date, only a limited number of studies reporting on the outcomes of MIEP have been published. In the present study, we report our initial experience with MIEP defined according to the latest the International Study Group for Pancreatic Surgery (ISPGS) guidelines.


Over a 14-month period, a total of 6 consecutive MIEP performed by a single surgeon at a tertiary institution were identified from a prospectively maintained surgical database. EP was defined as per the 2014 ISPGS consensus. Hybrid pancreatoduodenectomy (PD) was defined as when the entire resection was completed through minimally-invasive surgery, and the reconstruction was performed open through a mini-laparotomy incision.


Six cases were performed including 2 robotic extended subtotal pancreatosplenectomies with gastric resection, 1 laparoscopic-assisted (hybrid) extended PD with superior mesenteric vein wedge resection, 2 robotic-assisted (hybrid) PD with portal vein resection (1 interposition Polytetrafluoroethylene graft reconstruction and 1 wedge resection) and 1 totally robotic PD with wedge resection of portal vein. Median estimated blood loss was 400 (250-1500) ml and median operative time was 713 (400-930) min. Median post-operative stay was 9 (6-36) days. There was 1 major morbidity (Grade 3b) in a patient who developed early post-operative intestinal obstruction secondary to port site herniation necessitating repeat laparoscopic surgery. There were no open conversions and no in-hospital mortalities.


Based on our initial experience, MIEP although technically challenging and associated with long operative times, is feasible and safe in highly selected cases.
