Abstract
BACKGROUND: Intraoperative blood loss is one of the predictors of outcome of open hepatectomy. But the impact of blood loss in laparoscopic hepatectomy (LH) on postoperative outcomes is poorly understood. The aim of this study is to analyze the association between blood loss and postoperative outcomes after LH. METHODS: A retrospective analysis of prospectively maintained database of patients undergoing LH from 1995 to 2016 was performed. The data were divided into two groups based on the extent of blood loss: Group 1 (<250 ml) and Group 2 (≥250 ml). The basic characteristics and postoperative outcomes were compared between these groups. RESULTS: A total of 504 patients underwent 611 LH (Group 1: 414 and Group 2: 197). The mean age was 62.4 years. The most common indication was liver secondaries (71.7%). Major hepatectomy was performed in 37% cases. Mean operative time was 225 ± 110.5 min and estimated blood loss was 239 ± 399.4 ml (range 0-4500 ml). Group 2 had significantly higher number of patients with malignant lesions undergoing major hepatectomy, anatomical resection with higher requirement for blood transfusion, and longer hospital stay. The incidence of conversion rate, overall complications including liver failure, renal failure, and postoperative mortality, was significantly higher in Group 2. However, the bile leak rate was similar in the two groups. CONCLUSION: Intraoperative blood loss is most frequent in patients undergoing major LH. Blood loss ≥250 ml during LH may adversely affect the postoperative outcomes.
