ARTICLE HIGHLIGHTS
Research background

Mesenchymal tumors such as perivascular epithelioid cell neoplasm (PEComa) and inflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDC sarcoma) are very uncommon neoplasms in the liver, especially in the caudate lobe. Laparoscopic resection of such tumors in the caudate lobe has not been reported.

Research motivation

There is no report about laparoscopic resection of the rare hepatic mesenchymal neoplasms in the caudate lobe, and we wanted to explore the feasibility of laparoscopic resection of such tumors in the caudate lobe.

Research objectives

To assess the safety and feasibility of laparoscopic resection of rare caudate neoplasms like PEComa and IPT-like FDC sarcoma compared with open surgery.

Research methods

We analyzed the hospital stay duration, blood loss, operation time, time to removal of drainage tube, and occurrence of complications between the laparoscopic and open surgery groups.

Research results

The postoperative duration of hospital stay was significantly shorter in laparoscopic group, while the operation time, blood loss, time to removal of drainage tube, and occurrence of complications were comparable between the two groups.

Research conclusions

Laparoscopic resection of rare mesenchymal neoplasms like PEComa and IPT-like FDC sarcoma by isolated caudate lobectomy is safe and feasible.

Research perspectives

Our research indicates that laparoscopic caudate lobectomy is a prospective way to handle rare tumors in the caudate lobe.
