Inferior-Medial Approach to Laparoscopic Splenic Vessel-Preserving Distal Pancreatectomy

초록

Background and Objectives: Complete preservation of the splenic vessels is ideal during laparoscopic spleen- preserving distal pancreatectomy (LSPDP). However, this remains challenging and time-consuming because the vessels are often deeply embedded in the pancreatic parenchyma. Herein, we introduce our inferior-medial approach to laparoscopic splenic vessel-preserving distal pancreatectomy (lap-SVPDP) and evaluate its safety and feasibility. Methods: Forty-three patients underwent LSPDP performed by a single surgeon at our institution: 26 (60.5%) lap-SVPDPs with an inferior-medial approach and 17 with the laparoscopic Warshaw technique (lap-WT). We compared the outcomes of the 2 groups. No patient undergoing lap-SVPDP required conversion to laparotomy or lap-WT. Results: Most preoperative characteristics and postoperative outcomes did not differ between the 2 groups; neither the operation time nor the intraoperative blood loss differed despite the greater technical complexity of lapSVPDP. The mean tumor size was greater in the lap-WT than the lap-SVPDP group (P 5 .001). The splenic vein patency rate of the lap-SVPDP group was not inferior to that of the open SVPDP group treated by the same surgeon. Conclusion: Inferior-medial approach lap-SVPDP could be a safe and feasible technique for lap-SVPDP; neither blood loss nor operation time is increased.
