Impact of Postoperative Complications on Survival and Recurrence After Resection of Colorectal Liver Metastases

OBJECTIVE To study the effect of postoperative complications (POC) on overall survival (OS) and disease-free survival (DFS) after surgical resection of colorectal liver metastases (CRLM). SUMMARY BACKGROUND DATA Morbidity rates after liver resection can reach 45%. The negative impact of POC on oncologic outcomes has been reported in various types of cancer, especially colorectal. However, data on the consequences of POC after CRLM resection on long-term survival are scarce. METHODS Eligible studies examining the association between POC after CRLM resection and OS/DFS were sought using the PubMed and Web of Science databases. A random-effects model was used to calculate pooled effect estimat…
