Laparoscopic versus open radical resection for transverse colon cancer: evidence from multi-center databases.

Abstract

The role of laparoscopic approach is still a controversy for transverse colon cancer. Our investigation aimed to evaluate the perioperative and oncologic outcomes of laparoscopic versus open radical resection for transverse colon cancer based on evidence from multi-center databases. 416 patients with transverse colon cancer undergoing radical surgery were analyzed including 181 laparoscopic resections and 235 open resections from January 2004 to May 2017 based on multi-center databases. Perioperative and oncologic outcomes were compared. No statistical differences regarding the baseline characteristics were observed between the two groups except the procedure type. Compared with open approach, laparoscopic approach was associated with statistically longer operation time (209.96 vs. 173.31min, P = 0.002), significantly shorter time to soft food intake (4.73 vs. 6.01days, P = 0.034), and shorter postoperative hospitalization (12.05 vs. 14.44days, P = 0.001). In terms of oncologic outcomes, laparoscopic resection was correlated with statistically more lymph node retrieval (13.52 vs. 15.91, P = 0.002) and similar 5-year overall survival (91.2% vs. 89.1%, P = 0.356) and disease-free survival (89.6% vs. 86.0%, P = 0.873), compared with open resection. For patients with transverse colon cancer, laparoscopic approach can achieve several short-term advantages without decreasing long-term oncologic survival.
