Background
The latest studies on surgical and cost-analysis outcomes after laparoscopic distal pancreatectomy (LDP) highlight mixed and insufficient results. Whereas several investigators have compared surgical outcomes of LDP vs. open distal pancreatectomy (ODP) for adenocarcinomas, few similar studies have focused on pancreatic neuroendocrine tumors (PNETs).
Methods
We reviewed the medical records of PNET patients undergoing distal pancreatectomy between 2004 and 2014. Patients were divided into LDP vs. ODP groups. Demographics, relevant comorbidities, oncologic variables, and cost-analysis data were assessed. Survival and Cox proportional hazards analyses were used to evaluate outcomes.
Results
Of the 171 distal pancreatectomies for PNETs, 73 were laparoscopic, whereas 98 were open. Patients undergoing LDP demonstrated significantly lower rates of postoperative complications (P = 0.028) and had significantly shorter hospital stays (P = 0.008). On multivariable analysis, positive resection margins (P = 0.046), G3 grade (P = 0.036), advanced WHO classification (P = 0.016), TNM stage (P = 0.018), and readmission (P = 0.019) were significantly associated with poor survival; however, method of resection (LDP vs. ODP) was not (P = 0.254). The median total direct costs of LDP vs. ODP did not differ significantly.
Conclusions
In response to the recent considerable controversy surrounding the costs and surgical outcomes of LDP vs. ODP, our results show that LDP for PNETs is cost-neutral and significantly reduces postoperative morbidity without compromising oncologic outcomes and survival.
