Sickle cell disease (SCD) is one of the commonly inherited hemoglobinopathies in the Eastern Province of Saudi Arabia, 1,2 which is known to have an increased frequency of cholelithiasis. 3 Patients with SCD from the Eastern Province are known to have splenomegaly that persists into an older age group, and in some into adult life. 4,5 This is known to be associated with complications which necessitate splenectomy.6-9 When performed separately, elective cholecystectomy and splenectomy have been shown to be safe and effective in patients with SCD.6-10 Should cholecystectomy be performed concomitantly with splenectomy in patients with SCD?
Patients and MethodsA total of 112 patients had splenectomy for various hematological diseases at Qatif Central Hospital, over a period of 10 years, from 1986 to 1996. The most common indication for splenectomy was SCD. Seventy-four patients (66%) with SCD had splenectomy. Of these, 17 (23%) had concomitant splenectomy and cholecystectomy. The charts of these patients were reviewed for age at operation, sex, indication for splenectomy, whether gallstones were symptomatic or incidental, postoperative complications and outcome. The results were compared with the remaining patients with SCD, who only had splenectomy.The diagnosis of SCD was made on the basis of a positive sickling test and hemoglobin electrophoresis (Helena Laboratories Super Z Electrophoresis Kit). The histology of the spleen and gallbladder were obtained from the histopathology report. Preoperatively, all patients were hydrated with intravenous fluids at 1.5 times their maintenance rate, starting the night of the operation and continued postoperatively, until resuming full oral intake. Where necessary, blood transfusions were given preoperatively to restore their Hb to 10-12 g/dL and their hematocrit to 30%-40%. No exchange blood transfusions were performed. All patients received polyvalent Pneumovax (0.5 mL of PMY-immune 23, Lederle), as well as prophylactic antibiotics.
ResultsOf seventy-four patients with SCD who had splenectomy, 17 (23%) had concomitant splenectomy and cholecystectomy. There were nine females and eight males. Their ages ranged from 12-60 years (mean 24.4 years). Their HbS ranged from 67%-92.3% (mean 77%), and their HbF ranged from 6.2%-33% (mean 21.2%). Their demographic data, as well as indications for splenectomy and cholecystectomy, are shown in Table 1. The indications for splenectomy were hypersplenism in seven, recurrent splenic sequestration crisis in eight, and splenic abscess in two patients. In 11 patients gallstones were symptomatic in the form of recurrent right upper quadrant abdominal pain, while in the remaining 6 (35.3%), gallstones were discovered incidentally during routine ultrasound investigation.Histology of the spleens showed features of congestive splenomegaly in 15 patients with sclerosis and hemosiderosis in some of them, as well as sickling of red blood cells. In the remaining two patients with splenic abscess, there was evidence of ischemic infarction and abscess for...
