متن کاملStudy on laparoscopic spleen preserving distal pancreatectomy procedures comparing splenic vessel preservation and non-preservation.
BACKGROUND The purpose of this study is to investigate whether two types of laparoscopic spleen-preserving distal pancreatectomy (Lap-SPDP) techniques are being implemented safely. The study compares the clinical outcomes from laparoscopic Warshaw operation (Lap-W) with those from laparoscopic splenic vessels preserving SPDP (Lap-SPDP-VP) and considers the role of those operations. METHODS On...
