Spleen-preserving Distal Pancreatectomy or Distal Pancreatectomy With Splenectomy?

GOALS We designed this study to evaluate the efficacy of spleen salvage during distal pancreatectomy for patients with benign and borderline malignant tumors. BACKGROUND Despite the emphasis on its role, the spleen has commonly been removed in distal pancreatectomy. STUDY From January 2005 to July 2009, 82 patients underwent distal pancreatectomy with splenectomy (DPS) and 78 patients underwent spleen-preserving distal pancreatectomy (SPDP). Medical records were retrospectively reviewed. RESULTS There were no significant differences in demographics, final diagnoses, estimated blood loss, intraoperative transfusion, and operative time between the 2 groups. More perioperative complications occurred in the DPS group than in the SPDP group (P=0.0344). Consequently, postoperative hospital stay was significantly shorter in the SPDP group than in the DPS group (P=0.0273). In the follow-up survey, episodes of common cold or flu were apparently more frequent in the DPS group (P=0.047). More patients in the DPS group felt fatigue (P=0.0481) and poor health condition (P=0.0371). Less newly developed (P=0.0193) and aggravated diabetes mellitus (P=0.0361) were also observed in the SPDP group. Platelet counts on postoperative day (POD) 5, hemoglobin on POD 3, WBC counts, and CRP level on POD 2 were significantly higher in the DPS group than in the SPDP group and these differences continued to be significant for months after surgery. CONCLUSIONS In addition to frequent higher grade complications, prolonged hospital stays, and severe hematological abnormalities, DPS seemed to result in poor health condition based on the follow-up survey. Even an effort to preserve an adult spleen in distal pancreatectomy is worthwhile.
