Abstract

Purpose: Identifying the possible predictors of postoperative bleeding is advantageous to reduce healthcare costs and promote patients’ recovery. The aim of this study was to determine early postoperative bleeding predictors after bariatric surgery. Materials and Methods: This retrospective study was conducted using data from 2260 patients who underwent bariatric surgery. We diagnosed early postoperative bleeding by the following symptoms: abdominal pain, hypotension, tachycardia, hematemesis, melena, decreased hemoglobin level, the need for at least two units of packed red blood cells (PRBCs) transfusion, and reoperation within the first 48 h after surgery. Results: Our results showed the odds of early postoperative bleeding in laparoscopic Roux-en-Y gastric bypass (LRYGB) were higher than in laparoscopic sleeve gastrectomy (LSG) (OR 3.49, 95% CI 1.79 to 6.80). In addition, prior intragastric balloon (IGB) (OR 3.14, 95% CI 1.18 to 8.34) and oral non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) (OR 5.91, 95% CI 1.79 to 20.63) were positively associated with the occurrence of postoperative bleeding. In contrast, there was an inverse relationship between staple line oversewing and the odds of postoperative bleeding (OR 0.18, 95% CI 0.04 to 0.81). After stratification data based on the type of the surgery, the positive association between IGB and the odds of bleeding was constant in the LRYGB group. In the LSG group, use of non-aspirin NSAIDs was linked to a higher incidence of postoperative bleeding, while oversewing of the staple line lowered the incidence of this event. Conclusions: Our results demonstrated a positive association between type of procedure, history of IGB, and oral non-aspirin NSIADs use, as well as an inverse relationship between staple line oversewing and the odds of bleeding after bariatric surgery.
