We evaluated the effect of diabetes mellitus on mortality and morbidity after elective hepatic resections. Of 209 patients who underwent hepatic resections between April 1985 and July 1990, 49 (23.4%) were diabetic. Postoperative morbidity was more common among diabetics than among nondiabetics (75.5% vs 51.3%), mainly due to hepatic decompensation (55.1% vs 36.3%) and intraperitoneal sepsis (18.4% vs 6.3%). However, their incidence of hospital death (2% vs 2.5%), mean +/- SD postoperative hospital stay (36.1 +/- 20.2 days vs 29.4 +/- 28.2 days), and long-term survival were comparable with those of nondiabetics. Diabetics with and without complications were similar in preoperative or postoperative insulin requirement, duration of diabetes, and preoperative fasting glucose. Nevertheless, all eight patients with 24-hour urinary glucose excretion above 1 g developed complications. We conclude that diabetics are at a high risk of morbidity, but not of mortality after elective hepatic resection.
