Low pressure video endoscopic inguinal lymphadenectomy in the treatment of penile cancer: a historical control study
Background and Objective
To decrease the risk of complications of inguinal lymphadenectomy by investigating the value of low CO2 pressure video endoscopic inguinal lymphadenectomy in the treatment of penile cancer.
Methods
The clinical data of a total of 44 patients who underwent video endoscopic inguinal lymphadenectomy (VEIL) were collected for statistical analysis.
Results
The average operation time was ( 106.88 ± 17.93) min in low CO2 pressure (LP) group and ( 115.79 ± 20.29) min in normal CO2 pressure (NP) group. The average number of lymph nodes was (10.83 ± 2.14) in LP group and (11.16 ± 1.77) ml in NP group. The intraoperative PaCO2 value was (45.51 ± 4.57) mmHg in LP group and (50.77 ± 6.50) ml in NP group. The PH value of blood gas analysis was (7.35 ± 0.05) in LP group and (7.31 ± 0.04) ml in NP group. The incidence of emphysema was 2/25 in LP group while it was 9/19 in NP group. 2 cases of skin metastasis and 1 lung metastasis were observed in NP group, but not in LP group.
Conclusions
Decrease of CO2 pressure during operation will not increase the difficulty of the surgery. LP VEIL can reduce the risk of complications including hypercapnia and the subcutaneous or lung recurrence.
