Outcomes of liver surgery in the elderly population over 70 years
E. Melloul, N. Halkic, N. Demartines (Lausanne)
Objective: To evaluate the postoperative outcome in patients older than 70 years undergoing minor or
major liver surgery (more or less than 3 Couinaud’s segments), and compare the results with patients
below the age of 70 years.
Methods: Between 2000 and 2007, we retrospectively analyzed all liver resections performed at our
tertiary referral center. The patients were divided into 2 groups : > or = 70 years old (elderly group)
and < 70 years old (young group). Preoperative co-morbidities and early outcomes were analyzed.
Complications were assessed using a validated scoring system. Liver failure was defined using the
50/50 criteria.
Results: During the study period, 245 hepatectomies have been performed. Forty nine patients were
included in the elderly group and 151 in the young group. The mean age was 74 years (range 70-85)
and 52 years, respectively (p 70 years remain an
independant risk factor of mortality, as cardiac insufficiency in multivariate analysis. However, liver
function is interestingly not altered in the elderly.
