Total pancreatectomy for pancreatic malignancy with preservation of the spleen.

BACKGROUND

Total pancreatectomy may be necessary to achieve margin-negative resection for pancreatic cancer. However, despite the desirability of saving the spleen, the feasibility, safety, and oncological outcomes of spleen-preserving total pancreatectomy have not been studied in patients with malignancy involving the pancreatic neck or proximal body. The aim of this study was to report the efficacy of spleen-preserving total pancreatectomy using the Warshaw technique for patients with pancreatic malignancies.

METHODS

A retrospective analysis of patients who underwent total pancreatectomy for malignant pancreatic diseases between December 2006 and January 2018 focused on comparing the clinical outcomes between conventional operations with splenectomy and spleen-preserving total pancreatectomy using the Warshaw technique.

RESULTS

Thirty-eight patients among a total of 59 total pancreatectomies had the spleen preservation by the Warshaw operation. In this series, the pancreatic ductal adenocarcinomas resected with the Warshaw technique were of smaller tumor size but had greater rates of vascular invasion, resulting in the more frequent vascular resection. No patients had splenic complications requiring splenectomy, but two patients intended to have the Warshaw operation were converted to splenectomy because of splenic malperfusion. Asymptomatic perigastric varices were noted in 4 patients. Postoperative morbidity and mortality were comparable between the Warshaw and conventional operation groups. Recurrence-free and overall survival was similar in both groups.

CONCLUSION

In patients with pancreatic malignancy, total pancreatectomy with preservation of the spleen using the Warshaw technique achieves outcomes comparable with conventional total pancreatectomy with splenectomy in selected patients.
