Short-term preoperative diet modification reduces steatosis and blood loss in patients undergoing liver resection.
Surgery(2013)
摘要
Background. Steatosis and steatohepatitis have been associated with increased morbidity and mortality after liver resection. Our objective was to determine the effect of a preoperative calorie-restricted diet on steatosis and steatohepatitis in patients undergoing liver resection. Methods. We studied 111 consecutive patients who had major elective hepatic resections. More than 90% of the patients had cancer resections. The mean body mass index was 27.2; 32% had a body mass index >= 30. A week-long calorie- and fat-restricted diet was instituted in the most recent patient group (n = 51). We retrospectively evaluated steatosis and steatohepatitis in the diet and no-diet control groups. Clinical outcomes of the 2 groups, including complications and blood loss, were compared. Results. The preoperative diet patients had less steatosis (15.7% vs 25.5% of hepatocytes containing fat, P = .05) than the nondiet controls. A lower percentage of patients in the diet group had steatohepatitis than in the nondiet group (15% vs 27%, P =. 02). Preoperative diet patients had less mean intraoperative blood loss than nondiet patients (600 mL vs 906 mL, P = .002). There was no difference in overall or infectious complications between the groups. Conclusion. We have shown for the first time that short-term calorie restriction before liver resection significantly reduces both hepatic steatosis and steatohepatitis. Dietary modification also was associated with decreased intraoperative blood loss. This intervention is easily instituted; therefore, it is clinically feasible.
