When distal pancreatectomy is performed in benign disease or low-grade borderline malignancy, splenic preservation is usually recommended. There is a report from Memorial Sloan Kettering Center that the patient group with splenectomy has higher morbidity than non-splenectomy group in open distal pancreatectomy [2]. And spleen has a role in immunology, and there may be a possibility of post-splenectomy sepsis when spleen was removed. There are two methods of preserving the spleen, one is splenic vessel preserving method and another is splenic vessel sacrificing method (Warshaw technique). Splenic vessel preserving operation is associated with less complication associated with splenic infarction. However, this procedure is technically more demanding than splenic vessel sacrificing operation. Even after preservation of the splenic vessels, the patency of the vessels may not last long enough. There has been report on high incidence of the splenic venous obstruction compared to open surgery on long-term follow-up of the splenic vessel-preserved patients [3]. Subsequent multi-institutional studies showed that this higher rate of splenic vein patency may be related with technical inadequacy in early period of surgeon’s experiences [4]. When preserving splenic vessels is difficult or splenic vessels are injured during operation, Warshaw technique is a useful option. Warshaw technique is easy to perform compared to splenic vessel saving surgery with the advantages of preserving the spleen.
