Liver surgery – a single center five year experience

Abstract

Background: Different focal lesions including benign tumors, primary malignant tumors and metastasis from other organ malignancies frequently affect the liver. Aim of the study was to analyse the results of liver surgery in the last five years, focusing on long term follow-up. Methods: We conducted a prospective study of patients with liver lesions operated on in the time period from 2011 until 2016. Clinicopathological charecteristics and survival outcomes were analyzed as well as preoperative and surgical variables. Results: A total of 91 patients with liver lesions underwent surgery during the study. Mean patient age was 56,49 AE 13,75 years. The female-to-male ratio was 53:38. Operation time was 212 AE 77 min. Mean hospital stay was 9 AE 3,84 days. Mean follow-up was 36 AE 8 months. During followup 12 had reccurence, 7 of them were reoperated. Two patients underwent transcatheter arterial chemoembolization. 19 died, 8 lost of follow-up. 60 patients (65,9%) underwent one segment resection, 21 patients (23,1%) underwent hemihepatectomy and 7 patients (7,7%) had multiple segment resections. Morphological findings revealed that the most freaquently-operated pathology was liver metastasis (n=40), followed by primary malignant liver tumours in 26 cases and benign lesions in 25 cases. Conclusion: Liver surgery is complex surgical field with comparatively higher morbidity and mortality. Carefull patient preperation and consideration for operation as well as postoperative supervision is essential to obtain adequate results.
