Summary

Focal nodular hyperplasia of the liver (FNH) is a benign liver tumor that frequently occurs in women and is often associated with the use of oral contraceptives. The aim of this study was to report the outcomes of surgical management in patients with FNH, in terms of postoperative complications (POC). Retrospective and consecutive case series of patients with FNH surgically treated between 2010 and 2024 at Clínica RedSalud Mayor in Temuco. A supraumbilical midline laparotomy or a “J”- shaped laparotomy was performed, depending on the location of the lesion. The outcome was POC measured 30 days postoperatively. Other variables of interest were surgical time, hospital stay, mortality and follow-up. Descriptive statistics were used with calculation of percentages, measures of central tendency and dispersion Eleven patients with FNH with average age of 60.9±21.2, 90.9 % female underwent surgery. The mean FNH diameter was 8.0±1.6 cm. The average operation time was 55±16 minutes, and the media hospital stay was 3±1 days. POC occurred in one patient (9.1 %), who developed a seroma in the surgical wound. No reinterventions were required and no cases of mortality occurred. Average follow-up was 34±14 months. This series is notable for the older age of the cases and the diameter of the lesions. POC and mortality were similar to other series.
