ABSTRACT
BACKGROUND:
Laparoscopic sleeve gastrectomy (LSG) is nowadays the most popular bariatric procedure for obesity. However, whether LSG increases the risk of thrombosis remains unclear. The aim of this study was to investigate potential effects of LSG on coagulation system.METHODS:
Fifty-five obese patients underwent LSG between 2016 and 2018. The LSG was performed with pneumoperitoneum pressure maintained at 13 mmHg. Venous blood specimens were collected from each patient before surgery, at the end of pneumoperitoneum (i.e., 0 h after surgery), and at 24 h after surgery to determine prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), platelet count (PLT), D-dimer (D-D), red blood cell count (RBC), hematocrit (HCT), plateletcrit (PCT), cholesterol (CHOL), triglyceride (TRIG), and serum calcium (Ca). All patients were examined on the veins of the lower limbs by color Duplex sonography (CDS) before surgery and at 24 h after surgery, respectively.RESULTS:
All patients successfully underwent LSG. No severe surgery-related complications were observed during 1-month follow-up after operation. Preoperative BMI was 43.6 ± 8.3 kg/m2. The levels of coagulation factors were within the normal range before surgery, except a relatively higher PLT. The PT and D-D were increased at 0 h and 24 h after surgery (P < 0.05), whereas APTT was decreased (P < 0.05). The postoperative FIB remained similar to the preoperative one (P > 0.05). The CDS identified no thrombus in the veins of the lower limbs, either before surgery or at 24 h after surgery.CONCLUSIONS:
LSG may cause postoperative hypercoagulability of patients with obesity.Palavras-chave
