Video Endoscopic Inguinal Lymphadenectomy vs Open Inguinal Lymphadenectomy for Carcinoma Penis: Expanding Role and Comparison of Outcomes.

OBJECTIVE

To compare differences of morbidity profile, oncological yield, and efficacy between video endoscopic inguinal lymphadenectomy and open inguinal lymphadenectomy cases.

MATERIALS AND

METHODS

A total of 29 patients with proven squamous cell carcinoma of the penis were selected for inguinal lymphadenectomy from August 2013 to January 2017. Video endoscopic lymphadenectomy was performed on 1 limb and open inguinal lymphadenectomy was performed on the contralateral side. Relevant outcome data such as operative time, complication rate, number of lymph nodes removed, number of positive nodes, and recurrence during the follow-up period were collected, analyzed, and compared.

RESULTS

The mean operative time was significantly longer for the video endoscopic inguinal lymphadenectomy group (mean = 162.83 minutes) as compared with the open group (mean = 92.35 minutes). However, the mean numbers of lymph nodes removed were 7.6 in the endoscopic group and 8.3 in the open group. Postoperative complications occurred in 10 limbs (34.48%) in the open group and in 3 limbs (10.34%) in the endoscopic group. In the follow-up period ranging from 7 to 28 (mean 14) months, 2 patients died because of either distant or visceral metastasis.

CONCLUSION

The present study clearly outlines the fact that video endoscopic inguinal lymphadenectomy can deliver an equivalent lymph node yield similar to open inguinal lymphadenectomy with significantly less morbidity and is not affected by either the palpability or the number of palpable nodes. Thus, we believe that this minimally invasive technique can provide a prudent alternative for the management of the inguinal region in carcinoma of the penis.
