Technical considerations in distal pancreatectomy with splenic preservation.

Splenic preservation may be attempted when distal pancreatectomy is performed for nonmalignant disease. The splenic artery and vein can be preserved with meticulous control of the multiple small, thin-walled branches that tether these vessels to the pancreas, allowing splenic salvage. Mobilization of the spleen into the operative field, ligation of the short gastric vessels and splenectomy are not performed. Thus, the operative procedure may be accomplished in carefully selected patients with little increase in operative time or blood loss over conventional distal pancreatectomy with splenectomy.
