Abstract:
Objective:To investigate the feasibility and safety of single-position robotic assisted laparoscopic anterograde bilateral inguinal lymphadenectomy for penile cancer.Methods:The clinical data of 6 patients with penile cancer admitted to our hospital from January 2019 to January 2020 were retrospectively analyzed. The mean age was (52.0±8.6)years old. The pathology was primary focal squamous cell carcinoma, with 2 cases of high differentiation, and 4 cases of medium differentiation. All the 6 patients underwent single-position robotic assisted laparoscopic anterograde bilateral inguinal lymphadenectomy. Preoperative physical and imaging examinations indicated bilateral inguinal lymph node enlargement, and no distant metastasis was found in all of the 6 patients. The supine position was taken, with the head low and feet high about 15°, the legs straight and separated as far as possible in the shape of "Chinese eight" . The da Vinci robotic patient cart was placed between legs of the patient, after inserting the trocars. The external boundary of bilateral inguinal lymph node dissection was the line between the anterior superior iliac spine and 20 cm lower, the inner boundary was the pubic tubercle and its 15cm medial lower measurement, and the line between the inner boundary and the external lower edge was the lower boundary.Results:All the 6 operations were successfully completed without transfer to open surgery. Both sides of the inguinal lymph nodes were dissected at the same time. The space establishment and trocar insertion were performed simultaneously. There was no need for mobile robotic arm system during the operation. The average operative time was (105.0±20.5) min, and the amount of intraoperative blood loss was less than 50ml, the average hospital stay was(7±3) days. An average of(15.0±2.5) lymph nodes were dissected on each side. Intraoperative freezing suggested single positive lymph nodein 2 patients and no positive lymph node in 4 patients. There was no skin necrosis, 1 case of delayed wound healing, and 2 cases of lymphatic leakage. All patients were cured by conservative treatment. The 6 patients were followed up for 12-14 months, and there was no recurrence or metastasis.Conclusions:Single-position robotic assisted laparoscopic anterograde bilateral inguinal lymphadenectomy can achieve the expected surgical outcome, and has fewer perioperative complications. The surgery is safe and effective.
