The Importance of Determining Preoperative Serum Concentration of Carbohydrate Antigen 19-9 and Carcinoembryonic Antigen in Assessing the Progression of Colorectal Cancer.

Introduction: Many evidence indicates that Carcinoembryonic antigen (CEA) and Carbohydrate antigen 19-9 (CA 19-9) have strong reactivity with tumor cells and may serve as a useful marker in identifying patients with colorectal cancer (CRC).

Objectives: The goal of this study was to evaluate the relationship between preoperative concentration of serum levels of CEA and CA 19-9 and progression of colorectal cancer.

Methods: The retrospective study included 80 patients operated for colorectal cancer at the Clinic for General and Abdominal Surgery, Clinical Center of University of Sarajevo, from 2013 to 2018.

Radiofrequency Assisted Hepatic Parenchyma Resection Using Radiofrequent Generator (RF) Generator.

Introduction: The role of Radio frequent Generator (RF) has been extended from simple tumor ablation to routine hepatic resection. RF energy precoagulates the tissue and thus allows the closure of small blood vessels and bile ducts. The development of surgical techniques and modern technological advances have enabled liver resections to be significantly surgically better controlled in the sense of bleeding, and are more successful and safer for patients.
