Abstract
Objectives: The purpose of the present study was to compare hematological and clinical characteristics of patients who underwent sleeve gastrectomy before and after surgery
Methods: Medical records information from 2009 to 2014, for 395 male and female patients who underwent sleeve gastrectomy at King Khalid University Hospital (KKUH) were extracted according to preselected inclusion criteria. A paired t-Test was used to compare the changes in the hematological before and after surgery. Independent t-Test was used to evaluate differences among genders. All statistical analysis was conducted using SPSS version 22.
Results: Female patients were more than males by 60.3% to 39.7% with 25 years as the most frequent age, and morbid obese patients more than obese and overweight with 80.3%, 18.50% and .3%. significate changes were seen in BMI, MCV, PLT, HCT by comparing pre and post operatively results. 49 patients out of 145 showed improvement from Iron deficiency anemia after the surgery while 18 out of 250 patients developed the disease after the surgery. polycythemia was improvement in 9 patients out of 19 while 17 patients out of 376 showed development after the surgery.
Conclusion: Sleeve gastrectomy showed no significant relationship with iron deficiency anemia and polycythemia. However, it showed significant changes in hematological values such as MCV, PLT, HCT and BMI as a clinical characteristic.
