Influence of body mass index ≥30 on pure laparoscopic donor right hepatectomy

Abstract

Background: Pure laparoscopic donor right hepatectomy (PLDRH) for donors with obesity has not been previously investi-gated. This study aimed to investigate the influence of donor obesity (BMI ³30 kg/m2) on and clinical outcomes after PLDRH. Material/Methods: Records of all living donors who underwent PLDRH between November 2015 and May 2018 and open conven-tional donor right hepatectomy (CDRH) between January 2011 and October 2015 at Seoul National University Hospital were retrospectively reviewed. The donors were divided into 3 groups: PLDRH BMI ³30, PLDRH BMI <30, and CDRH BMI ³30. Results: Donors in the PLDRH BMI ³30 group (n=7) were compared with those in the PLDRH BMI <30 (n=65; control 1) and CDRH BMI ³30 (n=8; control 2) groups. Graft weight was significantly heavier in PLDRH BMI ³30 than in control 1 (P=0.012). The lowest hemoglobin (Hb) value was higher (P=0.014) and DHb% was lower (P=0.005) in PLDRH BMI ³30 than in control 1. Similarly, the lowest Hb value was higher (P=0.021) and DHb% was lower (P<0.001) in PLDRH BMI ³30 than in control 2. The peak alanine aminotransferase (ALT) (P=0.029) and DALT% were higher in PLDRH BMI ³30 than in control 2. No significant differences in hospital stay and postoperative complications were found between PLDRH BMI ³3 and control 1, as well as between PLDRH BMI ³3 and control 2. Conclusions: This study revealed that PLDRH is feasible in donors with obesity.
