Synchronous Surgery for Colorectal Cancer and Liver Metastases. Laparoscopic Colorectal Resection Improvesshort Term Outcomes

Abstract

Introduction: 25% of patients with colorectal cancer present with liver metastases of diagnosis. Long term survival is influenced by obtaining a complete removal of the primary tumor and liver metastases. Aim of this study was to assess short-term outcomes of combined resection of left colon and rectum and liver metastases. Comparing the results of the primary tumor, resection performed laparoscopically or by laparotomy. Method: From September 2006 to August 2021 34 patients underwent combined resection of colorectal cancer and synchronous liver metastases, 23 patients underwent laparoscopic colorectal resection (LPS Group), 11 undergoin resection by laparotomy. Right colonic resections were excluded from the study. Results: The groups resulted comparable in terms of patients and disease characteristics extent of liver resection lymphadenectomy and length if surgery. LPS group has a significantly lower blood loss (350ml vs 500ml,p<0,001).LPS group was associated with lower postoperative morbidity and shorter hospital stay (7 days vs 11 days p<0,001). The results of patients groups undergoing colon resection confirmed the significant reduction in postoperative morbidity and length of hospital stay. Conclusion: Laparoscopic approach of colorectal in patients undergoing simultaneous resection of liver metastases of laparoscopy is associated with reduction of blood loss, morbidity and postoperative hospital stay, without affecting the oncologic radicality. In simultaneous resections of colorectal cancer and liver metastases. Postoperative morbidity and hospital stay are mainly conditioned by the type of procedure rather than the extent of liver resection.
