ABSTRACT
BACKGROUND: Postresectional liver failure is the most frequent cause of fatal outcome following liver surgery. Diminished preoperative liver function in the elderly might contribute to this. Therefore, the aim of the present study was to evaluate preoperative liver function in patients <60 or >70 years of age scheduled for liver resection. METHODS: All consecutive patients aged <60 or >70 years who are about to undergo elective liver surgery between 2011 and 2013 and underwent the methacetin breath liver function test (LiMAx) preoperatively were included. Histologic assessment of the resected liver gave insight into background liver disease. Correlation between age and liver function was calculated with Pearson's test. RESULTS: Fifty-nine patients were included, 31 were aged <60 and 28 were aged >70 years. General patient characteristics and liver function LiMAx values (340 (137-594) vs. 349 (191-530) µg/kg/h, p = 0.699) were not significantly different between patients aged <60 and >70 years. Moreover, no correlation between age and preoperative liver function LiMAx values was found (R = 0.04, p = 0.810). CONCLUSION: Liver function did not seem to differ between younger and older patients.

BACKGROUND: The impact of postoperative complications on long-term outcomes after surgery for colorectal liver metastases (CRLM) remains controversial. During the last decade, advances in surgical as well as non-surgical treatment have increased resectability and altered outcomes. We sought to determine the influence of postoperative morbidity on disease-free (DFS) and overall survival (OS). METHODS: All patients undergoing liver resection for CRLM for the first time between 2000 and 2011 were retrospectively identified from a prospective database. Postoperative morbidity was classified according to Dindo-Clavien grade. A Dindo-Clavien grade ≥ 3a was considered a major complication. Primary outcomes were DFS and OS depending on the presence or absence of postoperative morbidity. RESULTS: Of the 266 included patients, 97 patients (37 %) developed postoperative complications, of whom 61 (23 %) had major complications. Median DFS and OS (5-year) were 17 and 53 months (42 %). The occurrence of postoperative morbidity did not significantly shorten OS (p = 0.130) and DFS (p = 0.101). However, major morbidity reduced DFS significantly (p < 0.05). CONCLUSION: In the present study, the occurrence of major postoperative complications was associated with diminished DFS. However, the effect of (major) complications on OS did not reach statistical significance.
