title: Laparoscopic spleen-preserving distal pancreatectomy for pancreatic neoplasms: a retrospective study.
abstract: OBJECTIVE
  To describe the clinical characteristics, technical procedures, and outcomes of patients undergoing laparoscopic spleen-preserving distal pancreatectomy (LSPDP) for benign and malignant pancreatic neoplasms.
  
  
  METHODS
  The clinical data of 38 patients who underwent LSPDP in the Sir Run Run Shaw Hospital between January 2003 and August 2013 were analyzed retrospectively. Surgical techniques for LSPDP included preservation of the splenic artery and vein (Kimura's technique) and ligation of the splenic pedicle with preservation of the short gastric vessels (Warshaw's technique).
  
  
  RESULTS
  There were no conversions to open surgery in the 38 patients. Splenic vessels were conserved during spleen-preserving pancreatectomy, except in two patients who underwent resection of the splenic vessels and preservation only of the short gastric vessels. The mean operation time was 123.2 ± 52.4 min, the mean intraoperative blood loss was 78.2 ± 39.5 mL, and the mean postoperative hospital stay was 7.6 ± 2.9 d. The overall rate of postoperative complications was 18.4% (7/38), and the rate of clinical pancreatic fistula was 13.2% (5/38). All postoperative complications were treated conservatively. The postoperative pathological diagnoses were 22 cases of benign pancreatic disease and 16 cases of borderline or low-grade malignant lesions. During a median follow-up of 38 mo (range: 5-133 mo), no recurrence was observed.
  
  
  CONCLUSIONS
  LSPDP is a safe, feasible and effective procedure for the treatment of benign and low-grade malignant tumors of the distal pancreas.
