Warshaw Technique in Laparoscopic Spleen-Preserving Distal Pancreatectomy: Surgical Strategy and Late Outcomes of Splenic Preservation

الملخص EN

Laparoscopic spleen-preserving distal pancreatectomy (LSPDP) can be accomplished with either the preservation or the resection of splenic vessels; the latter is also known as Warshaw technique.

Our study is designed to investigate the operation selection strategy when proceeding LSPDP and to evaluate the long-term outcomes of patients undergoing Warshaw surgery.

The medical records and follow-up data of patients who underwent LSPDP in Qilu Hospital, Shandong University, were reviewed retrospectively.

A total of thirty-five patients were involved in this study, including 17 cases of patients who were treated with Warshaw procedure (WT) while the other 18 cases had splenic vessels preserved (SVP).

Compared with the SVP group, the operative time and intraoperative blood loss in WT group were improved significantly.

The incidence of early postoperative splenic infarction was higher in WT group.

However, there was no report of splenic abscess or second operation.

Follow-up data confirmed that there was no significant difference in spleen phagocytosis and immune function compared with normal healthy population.

Our study confirms that LSPDP-Warshaw procedure is a safe and efficient treatment for the benign or low grade malignant tumors in distal pancreas in selected patients.

The long-term spleen function is normal after Warshaw procedure.

Preoperative assessment and intraoperative exploration are recommended for the selection of operation approaches.
