1442 Are Blood Group and Antibody Screening Necessary Before Emergency Laparoscopic Appendicectomy?

Abstract

Abstract Aim The incidence of bleeding complications in laparoscopic surgery are low. At present, there are no national guidelines on pre-operative blood group and antibody screening (G&S) in patients undergoing emergency laparoscopic surgery. The aim of this study is to establish the incidence of intraoperative bleeding requiring transfusion during emergency laparoscopic appendicectomy. In turn, this will indicate the necessity of routine preoperative G&S. Method Retrospective data collection of all emergency laparoscopic appendicectomy procedures at a large tertiary hospital from January 2015 to January 2020 (5 years). Patients having routine or open procedures were excluded. The transfusion department records were used to identify any patients receiving a transfusion intraoperatively. Results 1362 emergency laparoscopic appendicectomy procedures were performed during the 5-year period. 4/1362 (0.29%) patients received intraoperative transfusion of blood products. Of these, 3 patients had known haematological disorders. One patient was transfused for bleeding associated with intraoperative miscarriage. Conclusions No patients required transfusion for surgical haemorrhage. The small number of patients requiring transfusion were predictable because of pre-existing haematological disorders and clinical status. Our data is one of the largest series available and the results demonstrate that routine preoperative G&S is not justified. Instead, a selective approach would ensure high risk patients are appropriately screened. In event of vessel injury and major haemorrhage, O negative blood can be used. Furthermore, we estimate that elimination of a routine second G&S sample could have saved our institution approximately £2500 per year.
