Table 2.

Major and secondary surgical treatments were performed simultaneously for metastatic neuroendocrine tumours to the liver (n= 172)

Major operative interventions	n	%
Trisectionectomy (extended hepatectomy)	22	12.8%
Hepatectomy	49	28.5%
Bisegmentectomy/sectionectomy (partial hepatectomy)	34	19.8%
Segmentectomy	21	12.2%
Wedge resection	14	8.1%
RFA alone	18	10.5%
Cholecystectomy without resection	1	0.6%
No hepatic intervention	13	7.5%
Secondary interventions
Wedge resection	17	9.9%
RFA	23	13.4%
Segmentectomy	17	9.9%

Secondary procedures typically managed contralateral lesions not encompassed in the simultaneous major resection because of location or expected final liver volume. An additional 34 patients (19.8%) also underwent a prophylactic cholecystectomy to prevent chemical cholecystitis from future treatments, such as transarterial embolization.
