Robotic Spleen-Preserving Distal Pancreatectomy: The Warshaw and Kimura Techniques

Abstract

Spleen-preserving distal pancreatectomy offers an alternative surgical approach to the traditional distal pancreatectomy combined with splenectomy for removing benign and low-grade malignant lesions in the distal pancreas, avoiding complications associated with splenectomy. This procedure can be accomplished either by resecting and ligating the splenic vessels (Warshaw technique) or by preserving them (Kimura technique). Currently, the widespread use of minimally invasive surgery has established laparoscopic and robotic approaches for spleen-preserving distal pancreatectomy as valid and safe options for treating such conditions. Our protocol aims to describe how the Warshaw and Kimura techniques of spleen-preserving distal pancreatectomy can be performed robotically. The first patient is a 36-year-old female with a neuroendocrine tumor (NET) in the pancreatic body who underwent a spleen-preserving distal pancreatectomy with the ligation of the splenic vessels (WT). The second patient is a 76-year-old male with chronic pancreatitis presenting with a dilated main pancreatic duct in the tail of the pancreas who underwent a spleen-preserving distal pancreatectomy with a vessel-preserving approach (KT).
