The number of patients with end-stage renal disease who benefit from chroni
c dialysis is steadily increasing. This study was designed to assess abdomi
nal surgery in chronic hemodialysis (CHD) patients. A 7-year retrospective
study was conducted including all the patients on CHD who underwent abdomin
al surgery in our unit. These patients were separated into an elective and
an emergency surgery group. Forty-three patients underwent surgery. In the
elective surgery group (18 patients), the most common diseases were colorec
tal cancer, symptomatic gallbladder stones, and hernia. There was no death
related to surgery in this group, and only one patient developed a complica
tion (5%). In the emergency surgery group (25 patients), the most common di
seases were mesenteric ischemia and gastrointestinal bleeding from angiodys
plasia. Complications occurred in 10 patients (total morbidity rate, 40%),
and 6 of them died (mortality rate, 24%). Gastrointestinal elective surgery
in patients on CHD can be performed with low morbidity and mortality rates
. The emergency group was differentiated by the high prevalence of bleeding
from angiodysplasia and mesenteric infarction, as well as its high surgica
l mortality rate.
