Comparison of Kimura Versus Warshaw Technique for Laparoscopic Spleen-Preserving Distal Pancreatectomy

This study aims to compare the surgical outcomes of laparoscopic spleen-preserving distal pancreatectomy using the Kimura technique versus the Warshaw technique. The primary focus is on the rates of unplanned splenectomy, occurrence of severe complications, as well as intraoperative and perioperative outcomes of both techniques.
