Purpose:
The aim was to compare the short-term and long-term outcomes of patients with metastatic colorectal cancer (CRC) undergoing laparoscopic versus open colorectal resection with simultaneous resection for liver metastases. Currently there is a lack of studies that have investigated the oncosurgical aspects and the short and long-term outcomes from these procedures.
Materials And Methods:
A retrospective study of patients who underwent simultaneous resections for CRC and synchronous liver metastases between 2008 and 2019 in 2 university affiliated medical centers.
Results:
Sixty-three patients were identified of whom 21 had successful laparoscopic simultaneous resections. In 43% of patients, the primary tumor was located in the right colon. The 3-year overall survival and disease-free survival rates were 87% and 48%, respectively. When compared with a separate control group of 42 patients who underwent conventional open resections, the laparoscopic approach was associated with an increased operative time (286 vs. 225 min, P=0.05), but a shorter hospital stay (6 vs. 8 d, P=0.008).
Conclusions:
Simultaneous laparoscopic colorectal and parenchymal sparing liver resection for metastatic CRC is safe, feasible, and it is a preferable approach because of better short-term outcome compared with open surgery while not compromising survival and disease recurrence.
