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

BACKGROUND: Colorectal cancer invading the adjacent organs/structures is detected in 5% to 20% of all surgical interventions performed for the management of colorectal cancer. OBJECTIVE: Our purpose is to verify the safety and feasibility of laparoscopic surgery for the treatment of locally advanced colorectal cancer invading the adjacent organs. DESIGN: This is a retrospective study. SETTINGS: The study was conducted at a single institution in Japan. PATIENTS: 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. MAIN OUTCOME MEASURES: The primary outcome measures were curative resection rate, morbidity rate, and recurrence of laparoscopic and open multivisceral resection in patients with colorectal cancer. RESULTS: 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
