Purpose: Laparoscopic sleeve gastrectomy (LSG) is currently the most common bariatric surgery in the world. Although it appears to be a safe treatment for obesity, it is still at risk of complications. The latest literature shows that postoperative bleeding occurs in 2-4% of cases, and up to 3% of cases requires reoperation for hemostasis. The aim of the study is to assess the effect of tranexamic acid (TXA) on hemorrhagic events and the reoperation rate in patients undergoing LSG.
Methods: The study was designed as a retrospective analysis of patients undergoing LSG. We investigate the patients 6 months before and 6 months after introducing the prophylaxis doses of TXA into our bariatric protocol (non-TXA group vs TXA group).
Results: Three hundred fourteen patients underwent LSG in a high-volume center from 2016 to 2017. After introducing TXA, a statistically significant reduction in the incidence of hemorrhage during surgery was observed (22.3% vs 10.8%, p = 0.006). There was a statistically significant reduction in the need for the staple line oversewing (10.2% vs 1.9%, p = 0.002). The mean operating time and the mean length of hospital stay were significantly higher in the non-TXA group than TXA group (63.1 vs 53.7 min, p < 000.1; 2.3 vs 2.1, p = 0.02). In both groups of patients, no venous thromboembolism or other complications occurred within 6 months after the surgery.
Conclusions: The prophylactic doses of TXA may be useful in reducing the hemorrhagic events during LSG. It may also shorten the length of hospital stay and the operating time.
