No large-scale clinical study has been done to show the standard surgical boundary and efficacy of laparoscopic para-aortic lymphadenectomy (LPAL).
Therfore, this study aimed to evaluate the feasibility, efficacy, and standard surgical boundary of LPAL performed up to the left renal vein level in gynecological malignancies.
Medical records of 333 patients were retrospectively reviewed. All cases had gynecologic malignancies and had an operation including LPAL by a single surgical team between November 2003 and May 2018.
Three hundred twenty-six patients underwent LPAL as part of their staging, restaging, or debulking surgery. Seven patients with isolated para-aortic lymph node recurrence underwent a repeat LPAL. The median age and body mass index were 54 years (range, 28-81 years) and 26.0 kg/m
(range, 20.3-37.2 kg/m
), respectively. The median operating time was 60 minutes (range, 24-135 minutes), and the median number of harvested para-aortic lymph nodes was 12 (range, 6-49). There were 11 cases of complications: 5 of major vessel injuries (3 inferior vena cava, 1 aorta, and 1 common iliac vein), 2 lymphocysts, 2 cases of chylous ascites, a cisterna chyli rupture, and 1 case of ureteric injury. There were 2 conversions to laparotomy: 1 left common iliac vein laceration that needed to be repaired and removal of an enlarged para-aortic lymph node completely.
It is feasible and efficient to perform LPAL to the left renal vein level for women with gynecologic malignancies by well-trained gynecologic oncology surgeons according to our suggested standard surgical boundary.
