Comparison of Laparoscopic Distal Pancreatectomy with or without Splenic Preservation.

Laparoscopic distal pancreatectomy (LDP) has gained large popularity in recent years, although the choice of whether to preserve the spleen has remained inconsistent. The aim of our study was to report our experiences with LDP and to provide evidence for the safety of the operative technique and an evaluation index of splenic function. We retrospectively evaluated all LDPs performed at our institution between March 2008 and February 2012. Cases were divided into a laparoscopic spleen-preserving distal pancreatectomy (LSPDP) group (n = 14) and an LDP with splenectomy (LDPS) group (n = 19). Parametric and nonparametric statistical analyses were used to compare perioperative and oncologic outcomes. Demographic characteristics, operating time, length of stay, estimated blood loss, transfusion requirement, pathologic diagnosis, and complication rate were similar between groups. Patients who underwent LDPS tended to have larger masses and lower pancreatic fistula rates, but these differences were not significant. White blood cell (WBC) counts were significantly higher in the LDPS group than in the LSPDP group on postoperative days 1 and 7. To avoid splenectomy-associated complications, preservation of the spleen and especially the splenic vessels are preferred. This procedure can be performed safely and feasibly. Lower postoperative WBC counts may imply better splenic function.
