Abdominal surgery for patients on maintenance hemodialysis

Despite the growing number of major surgical procedures being performed for patients on maintenance hemodialysis, few reports focus on the management and outcome of such patients, especially those undergoing major abdominal surgery. We conducted a retrospective review of 30 patients on maintenance hemodialysis who underwent abdominal surgery, 20 of whom underwent an elective operation and 10, an emergency operation. The indications of elective surgery included gastrointestinal cancer, biliary tract disease, and abdominal aortic aneurysm, while those for emergency surgery mainly involved gastrointestinal perforation or bleeding. There were no statistically significant differences between the elective group and the emergency group regarding either the mean time on hemodialysis or the preoperative clinical data. The morbidity and mortality rates were 15% and 10%, respectively, for the patients who underwent elective surgery and 50% and 70%, respectively, for those who underwent emergency surgery (P<0.01 andP<0.05, respectively). Those patients with more than a 2-year history of hemodialysis had a significantly higher mortality rate following abdominal surgery than those with less than a 2-year history (P<0.01). Thus, the morbidity and mortality rates of patients on maintenance hemodialysis who require major abdominal surgery are significantly high, which reinforces the need to further improve the intensive perioperative management of such patients.
