Role of tranexamic acid in reducing perioperative blood loss in transthoracic esophagectomy

Background and objectives: Transthoracic esophagectomy is usually associated with significant perioperative bleeding and blood loss. The present study investigated the role of prophylactic tranexamic acid on intra- and postoperative blood loss and the need for blood transfusion in transthoracic esophagectomy (Ivor Lewis esophagectomy). Materials and Methods: Patients who underwent laparotomy and right thoracotomy with intrathoracic anastomosis for esophageal malignancy were enrolled in the study. The enrolled cases were divided into two groups namely Group A and B. Informed consents were obtained from all the enrolled patients. Group A patients received a standard dose of 1 gram of intravenous tranexamic acid one hour before the beginning of surgery while Group B patients did not receive any tranexamic acid before or after the surgery. Peroperative blood loss was estimated and noted. Post-operative blood loss was assessed from the surgical drains. Results: A total of 55 cases were included in the study. Group A and B had 27 and 28 cases respectively. The mean age of the Group A and Group B patients was 60.1 ± 6.2 and 60 ± 6.9 years respectively. Out of 27 cases in Group A, 7 (25%) patients had a postoperative haemorrhage (blood loss) up to 300 ml and among the remaining 20, only 2 (7%) patients required blood transfusion as hematocrit fell below 20%. Compared to Group A, patients in Group B who did not receive preoperative tranexamic acid, 21(75%) patients had postoperative haemorrhage up to 300 ml (Group A vs. Group B: p=0.0002). Regarding intraoperative blood loss no significant (p >0.05) difference was observed among the cases in two groups. Conclusion: The study revealed that administration of prophylactic tranexamic acid resulted into fewer postoperative blood loss in transthoracic esophagectomy. IMC J Med Sci 2022; 16(1): 003.
