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.
ABSTRACT
Objective To discuss the surgical strategy and clinical effects of robotic assisted laparoscopic antegrade inguinal lymphadenectomy for penile cancer.Methods We retrospectively analyzed the clinical data and surgical strategy on the 7 cases,who undergoing robotic assisted laparoscopic antegrade inguinal lymphadenectomy,from August of 2016 to August of 2017.The mean age of 7 patients was (49.7 ± 7.5) years old,ranged from 40 to 62 years old,the mean BMI was (27.97 ± 3.86) kg/m2,ranged from 21.76 to 33.21 kg/m2 . There were 4 cases of T1,2 cases of T2,1 case of T3,1 case of N1,3 cases of N2,3 cases of N3 according to TNM stages.Preoperative preparation was as follows,preoperative cardiopulmonary assessment,inguinal and pelvic CT or MRI,ultrasound of lower extremity venous,bowel preparation.The patients were placed in a supine position,with an indwelling catheter,with the head positioned lower than the hip at an angle of about 15 degrees,legs were spread apart around 45 degrees,and both knees were slightly bent and externally rotated.The da Vinci robotic patient cart was pushed forward between legs of the patient.A blunt separation was carried out between Scarpa's fascia and the surface of the aponeurosis of the obliquus externus abdominis prior,then subcutaneous space was established by a self-made balloon dilatation.Results 7 cases were completed successfully without robot reposition without any conversion.Operative time of each side ranged from 50 to 90 min (70.0 ± 12.5)min.The blood loss of each side was less than 10 ml.In the 7 cases,the number of nodes removed from left inguinal region ranged from 7 to 18 (14.0 ±3.3).The number of nodes removed from right ranged from 5 to 21 (11.0 ± 3.3).Pelvic lymphadenectomy was completed in the meantime by original trocar site on 4 cases.Till now,no perioperative complications,such as flap necrosis,delayed healing of incision,cellulitis,occurred in inguinal region,except lymphorrhagia in 3 cases.During a follow-up within 3-14 months,there was no recurrence or metastasis in 6 cases except one died from tumor progression with systemic metastasis.Conclusions Antegrade inguinal lymphadenectomy for penile cancer by using Da Vinci robotic surgical system is safe and effective.This technique also appears to diminish the wound related complications associate with the standard open approach.Compared with the similar surgery,we conducted bilateral inguinal lymphadenectomy without patient cart reposition,which simplify the procedure and reduce the using of trocar.According to individual clinical conditions,pelvic lymphadenectomy also can be completed in the meantime by original trocar.

ABSTRACT
OBJECTIVE: The aim of this study was to investigate the clinical effects of sartorius tendon transposition versus sartorius transposition during bilateral inguinal lymphadenectomy of radical vulvectomy. METHODS: A total of 58 vulvar cancer patients who had surgery from May 2007 to October 2013, in which 30 patients received sartorius transposition and 28 patients received sartorius tendon transposition. All patients were matched by age, body mass index, stage, histology, and grade. Intraoperative variables and postoperative complications, recurrence, progression-free survival (PFS), and overall survival (OS) and postoperative life quality were compared and analyzed. RESULTS: No significant differences were found at median surgical times and amounts of bleeding (p=0.316 and p=0.249, respectively), neither at the incidences of groin cellulitis and lymphocele (p=0.673 and p=0.473, respectively), but the recovery times of the inguinal wounds were shorter (p=0.026) and the incidences of wound break and chronic lymphedema were significantly decreased in the tendon transposition group (p=0.012 and p=0.022, respectively). Postoperative quality of life in tendon transposition group was significantly improved as indicated by the EORTC QLQ-C30 questionnaire. Recurrences were similar (p=0.346) and no significant differences were found at PFS and OS (p=0.990 and p=0.683, respectively). CONCLUSION: Compared to sartorius transposition, sartorius tendon transposition during inguinal lymphadenectomy led to improved patient recovery, reduced postoperative complications, and improved life quality without compromising the outcomes.
