ARTICLE HIGHLIGHTS
Research background

Resection of hepatic metastasis from neuroendocrine tumors (NETs) improves quality of life and prolongs 5-year survival. Ablation can be utilized with surgery to achieve complete resection. Although several studies report long-term outcomes for patients undergoing ablation, none have explored perioperative effects of ablation in patients with metastatic NETs.

Research motivation

Currently, there is no literature on whether perioperative ablation increases risk of adverse outcomes in patients undergoing hepatic metastasectomy.

Research objectives

Our objective was to determine if intra-operative ablation during hepatectomy increases risk of adverse outcomes such as surgical site infections (SSIs), bleeding, and bile leak.

Research methods

We performed a retrospective analysis of the hepatectomy module of the National Surgical Quality Improvement Program database from 2015-2019 to determine the odds of SSIs, bile leaks, or bleeding in patients undergoing intraoperative ablation when compared to hepatectomy alone.

Research results

Of the 966 patients included in the study, 298 (30.9%) underwent ablation during hepatectomy. There were 78 (11.7%) patients with SSIs in the hepatectomy alone group and 39 (13.1%) patients with a SSIs in the hepatectomy with ablation group. Bile leak occurred in 41 (6.2%) and 14 (4.8%) patients in the two groups, respectively; bleeding occurred in 117 (17.5%) and 33 (11.1%), respectively. After controlling for confounding variables, ablation did not increase risk of SSI (P = 0.63), bile leak (P = 0.34) or bleeding (P = 0.07) when compared to patients undergoing resection alone on multivariate analysis.

Research conclusions

Ablation is safe in the perioperative period and does not increase the risk of infection, bleeding, or bile leak in patients undergoing hepatic resection for neuroendocrine liver metastasis.

Research perspectives

Future studies should focus on whether size, number, or relationship to vascular structures influences perioperative outcomes in this cohort of patients.
