Initial experience of robotic anterior pelvic exenteration at a single institute.

OBJECTIVE: To present the initial experience with robotic anterior pelvic exenteration in patients with advanced pelvic cancer at Galaxy Care Laparoscopy Institute, Pune, India. METHODS: A retrospective chart review of data from 10 patients with advanced cervical carcinoma and bladder involvement or with vault recurrence following hysterectomy who were treated at the study hospital between November 2009 and May 2011. Clinicopathologic data and postoperative data including operative time, blood loss, blood transfusions, hospital stay, lymph node yield, and complications were recorded. RESULTS: The mean operative time was 180 minutes, the mean blood loss was 110mL, and the mean duration of hospital stay was 5 days. There were no treatment-related morbidities or mortalities. A mean parametrial clearance of 3cm with a distal vaginal margin of 3.5cm was achieved. All patients had tumor-free margins. The mean number of harvested lymph nodes was 24. Six patients had positive lymph nodes on pathologic examination and were treated with chemoradiotherapy. At a median follow-up of 11 months, 8 patients were disease-free. CONCLUSION: Robot-assisted anterior pelvic exenteration had favorable operative, pathologic, and short-term clinical outcomes. A large multicenter study is required to confirm the results.

Nerve-sparing radical hysterectomy made easy by laparoscopy.

STUDY OBJECTIVE: To evaluate the technical feasibility of nerve-sparing radical hysterectomy performed laparoscopically. PATIENTS: Thirty-five women with cervical cancer stage Ia1 or Ib1. INTERVENTIONS: All patients underwent laparoscopic nerve-sparing hysterectomy. MEASUREMENTS AND MAIN RESULTS: Oncologic results were comparable to those of conventional laparoscopic radical hysterectomy. There was complete recovery of bladder function after removal of the Foley catheter. Results of urodynamic studies at 3 weeks after surgery were normal. CONCLUSION: Oncologic and functional results are comparable to those of conventional laparoscopic radical hysterectomy. Magnification enabled by laparoscopy is helpful in better dissection and preservation of nerve anatomy.

Indian experience of robotics in gynecology.

AIMS: To study the role of robotics in various gynaecological cases, benign and malignant. MATERIALS AND METHODS: A total number of 80 cases have been analyzed. Operative time, estimated blood loss, hospital stay, complications, conversion rates have been retrospectively studied in all cases. Nodal yield, vaginal margin and paracervical clearance have been studied in all malignant cases. This investigation was conducted at a single minimal access surgery institute. RESULTS: Of total 80 cases, 29 were benign and 51 were malignant cases. In benign cases, total robotic hysterectomies were 24, 2 cases of tubotuboplasty, 1 case of endometriotic cyst excision, 1 case of metroplasty and 1 case of rectovaginal fistula. In 51 cases, 37 of radical hysterectomy, 9 exenterations and 6 were parametrectomy. In benign cases, mean operative time was 80 min, estimated blood loss was 20 ml, mean hospital stay was for 1 day, no major complications and no conversions. In malignant cases, mean operative time was 122 min, estimated blood loss was 50-100ml, 2 cases of ureteric fistulas and no conversions, nodal yield was 30, vaginal margin was 2.5-3.8 cm and para cervical clearance was 3-3.5 cm. CONCLUSIONS: Ours is the largest series of robotic surgery in gynecological procedures in India. Benign and malignant cases were addressed robotically showing the feasibility.

Single-site laparoscopic radical hysterectomy using conventional ports and instruments.

STUDY OBJECTIVE: To study the technical feasibility of performing a radical hysterectomy via laparoscopic single-site surgery LESS. PATIENT: A 45-year-old woman with cervical cancer stage IA2. INTERVENTION: Biopsy report showed invasive keratinizing squamous cell carcinoma, grade II. We duplicated the steps of our "Pune technique" of laparoscopic radical hysterectomy to perform a radical hysterectomy via laparoscopic single-site surgery using conventional ports and instruments. MEASUREMENTS AND MAIN RESULTS: Oncologic clearance was comparable to that of conventional laparoscopic radical hysterectomy. Operative time was 120 minutes, and blood loss was 50 mL. CONCLUSION: Reduced port laparoscopic radical hysterectomy is technically feasible. Oncologic clearance and functional results are comparable to those of the multiport variant, with good cosmetic results.

Understanding the pelvic anatomy.

The pelvic anatomy is constant, with few variations. It has a distinct appearance when observed using the 2-dimensional laparoscope. Thus it is important to master the laparoscopic anatomy and use this knowledge to perform better surgery. The laparoscope offers better vision in a narrow space and thus helps better understanding of the anatomy than what can be seen during open surgery. The objectives of this video are to enable the observer to become familiar with the surgical anatomy, to apply anatomical knowledge to develop fine surgical skills, and to address the myths of open surgical anatomy. The lucid graphics, images, and commentary will enable easy understanding of the pelvic anatomy.

Nerve-sparing robotic radical hysterectomy: our technique.

Robotic surgery is now becoming accepted for treatment of gynaecological malignancies. Nerve preservation during radical hysterectomy is increasingly being offered due to improved post-operative bladder and sexual function. We aimed to demonstrate the feasibility of performing a nerve-sparing radical hysterectomy robotically and to assess the oncological and functional outcomes associated with this surgery. Between August 2011 and January 2013, a total of 12 non-consecutive patients underwent robotic surgery for early stage cervical cancer at our institution. Patients comprising FIGO stage IA2 to IB1 were treated with nerve-sparing robotic radical hysterectomy using a C1 (Querleu-Morrow classification) type technique. The feasibility, operative time, blood loss, oncological outcome and post-operative bladder function were assessed. All the procedures were completed robotically without conversion to laparoscopy or laparotomy. The mean age of the patients was 56 years (range 44-76) and their mean body mass index was 22.6 kg/m(2) (range 18.1-26.4). The mean operative time was 156 min (range 120-250); the mean blood loss was 120 ml (50-250). The Foley catheter was removed on the third post-operative day, with full recovery of bladder function in all patients except one who required prolonged catheterisation for 3 weeks. Residual urine was 40 ml (range 30-80). Parametrial margins of 2.5-3 cm, distal vaginal margins of 2-2.5 cm and a mean nodal harvest of 24 (range 18-30) were achieved. The mean hospital stay was 3 days (range 2-6). The median follow-up is 12 months. There is no loco-regional recurrence. All the patients are sexually active. Robotic nerve-sparing radical hysterectomy is technically feasible to perform, and is oncologically safe for early stage cervical carcinoma.

Robotic total pelvic exenteration.

INTRODUCTION: Pelvic exenteration is now becoming widely acceptable as a curative procedure rather than a palliative one. Performing these surgeries by minimally invasive techniques helps to improve the quality of life and decrease the morbidity of these extensive procedures. AIMS AND OBJECTIVES: To demonstrate the feasibility of performing a total pelvic exenteration robotically, and to study the morbidity associated with such extensive surgery. MATERIALS AND METHODS: A 35-year-old female with advanced cervical cancer presented with a vesicovaginal fistula and a rectovaginal fistula. In view of these, we performed a total robotic pelvic exenteration with colo-anal anastomosis and uretero-sigmoidostomy. The patient refused an ileal-loop conduit for urinary tract diversion due to social reasons associated with a stoma. RESULTS: The total operative time was 240 min and the console time was 120 min. The estimated blood loss was 300 ml and the intensive care unit stay was 2 days. Post-operatively, the patient had good faecal and urinary continence and good quality of life.

More with LESS: a novel report of nerve sparing radical hysterectomy performed using LESS.

Laparoendoscopic single-site surgery (LESS) and natural orifice translumenal endoscopic surgery are now being used in gynecologic oncologic procedures. We used our expertise with LESS to perform nerve-sparing laparoscopic radical hysterectomy. A 45-year-old woman with stage IA2 cervical cancer was referred to us. The biopsy specimen showed grade II invasive keratinizing squamous cell carcinoma. We duplicated the steps of our laparoscopic nerve-sparing radical hysterectomy procedure to perform a nerve-sparing radical hysterectomy via LESS using conventional ports and instruments. Oncologic clearance was comparable to that in conventional laparoscopic radical hysterectomy. Bladder function recovered completely after removal of the Foley catheter. Nerve-sparing laparoscopic radical hysterectomy using fewer ports is technically feasible. The oncologic clearance and functional results are comparable to those in the multiport variant.
