Introduction/Background This study is aimed to investigate the possibility of pre-operative oral oil administration in displaying the chylous tubes and preventing chylous leakage in laparoscopic para-aortic lymphadenectomy in gynecologic surgeries.
Methodology In this retrospective study, 30 patients with gynecological malignancies who had indications for laparoscopic para-aortic lymphadenectomy up to the renal vessels were give pre-operative oral oil (oil administration group) (n=15) or not (control group) (n=15) at our hospital between September 2017 and June 2018. The chylous tubes displaying rate, incidence of chylous leakage and other perioperative datum of the two groups were compared.
Results uccessful display of chylous tubes was observed in 93.3% (14/15) patients in the oil administration group. The chylous leakage was 0 in the oil administration group, and 33.3% (5/15) in the control group. The postoperative drainage duration (4.1±1.0d vs 7.6±1.4d, P=0.000), somatostatin application time (0d vs 5.9±0.8d), and post-operative hospital stay (6.0±2.3 d vs 9.1±2.1d, P=0.001) were significantly shorter in the oil administration group. The total cost is lower in the oil administration group (4972.52±80.54dollars vs 6260.80±484.47 dollars, P=0.000).
Conclusion Pre-operative oil administration is a feasible and effective method to display the chylous tubes and to prevent the chylous leakage in para-aortic lymphadenectomy.
