Donor safety in live donor laparoscopic liver procurement: systematic review and meta-analysis

Donor safety is a major concern in live organ donation. Live donor laparoscopic liver procurement is an advanced surgical procedure that is performed in highly specialized centers. Since its first report, not much progress has been endeavored for that procedure. We planned to include all the randomized and comparative nonrandomized studies. Patients’ population: live donors who are submitted to organ procurement via laparoscopy. Out of 5,636 records retrieved from the literature, only seven nonrandomized studies were included in this review, which encompassed 418 patients, 151 patients of whom underwent laparoscopic procurement. The quality scores for the included studies ranged from 66 to 76 %. The operative time was significantly shorter in the conventional open group (SD = 0.863, 95 % CI 0.107–1.819). Blood loss in the laparoscopic group was comparable with the conventional open approach (SD = −0.307, 95 % CI −0.807 to 0.192). In subgroup analysis, laparoscopy was protective against blood loss in laparoscopic parenchymal dissection (SD = −1.168, 95 % CI −1.758 to −0.577). The hospital stay was equal in both groups. Patients in laparoscopic group consumed fewer analgesics compared with conventional open group (SD = −0.33, 95 % CI −0.63 to −0.03). Analgesics use was lower in the laparoscopic group compared with the conventional approach. The rate of Clavien complications was equal in both groups (OR 0.721, 95 % CI 0.303–1.716). No difference was found between subgroup analysis based on the harvested liver lobe. Funnel plot and statistical methods used revealed low probability of publication BIAS. Live donor laparoscopic liver procurement could be as safe as the conventional open approach. Lower blood loss and lower consumtion of analgesics might be offered in the laparoscopic approach.
