Short- and Long-term Outcomes of Minimally Invasive Versus Open Multivisceral Resection for Locally Advanced Colorectal Cancer.

Abstract

Colorectal cancer invading the adjacent organs/structures is detected in 5% to 20% of all surgical interventions performed for the management of colorectal cancer. Our purpose is to verify the safety and feasibility of laparoscopic surgery for the treatment of locally advanced colorectal cancer invading the adjacent organs. This is a retrospective study. The study was conducted at a single institution in Japan. We compared the morbidity, appropriate oncological resection, and disease-free survival of laparoscopic and open multivisceral resection in patients with colorectal carcinoma in the period between 2007 and 2015. The primary outcome measures were curative resection rate, morbidity rate, and recurrence of laparoscopic and open multivisceral resection in patients with colorectal cancer. Thirty-one patients received laparoscopic surgery, and 50 received open surgery. The amount of blood loss was smaller in the laparoscopic group than in the open group (60 vs 595 mL, p < 0.01). Curative surgery was performed in 46 patients of the open group (92.0%) and in 30 patients of the laparoscopic group (96.8%). Days until oral intake (5 vs 7 days, p < 0.01) and postoperative hospital stay (14 vs 19 days, p < 0.01) were shorter in the laparoscopic group. Overall morbidity was not different between the groups (22.5% vs 40.0%). Three-year disease-free survival rates were 62.7% in the open group and 56.7% in the laparoscopic group (p = 0.5776). This study was a retrospective small study conducted at a single institute. Laparoscopic multivisceral resection may be a safe, less invasive alternative to open surgery, with less blood loss and shorter hospital stay, and was not inferior to open surgery based on long-term oncological end points.
