Total Laparoscopic Hysterectomy Utilizing a Robotic Surgical System

Objectives:

To describe the use of a robotic surgical system for total laparoscopic hysterectomy.

Methods:

We report a series of laparoscopic hysterectomies performed using the da Vinci Robotic Surgical System. Participants were women eligible for hysterectomy by standard laparoscopy. Operative times and complications are reported.

Results:

We completed 10 total laparoscopic hysterectomies between November 2001 and December 2002 with the use of the da Vinci Robotic Surgical System. Operative results were similar to those of standard laparoscopic hysterectomy. Operative time varied from 2 hours 28 minutes to 4 hours 37 minutes. Blood loss varied from 25 mL to 350 mL. Uterine weights varied from 49 g to 227 g. A cystotomy occurred in a patient with a history of a prior cystotomy unrelated to the robotic system.

Conclusion:

Total laparoscopic hysterectomy is a complex surgical procedure requiring advanced laparoscopic skills. Tasks like lysis of adhesions, suturing, and knot tying were enhanced with the robotic surgical system, thus providing unique advantages over existing standard laparoscopy. Total laparoscopic hysterectomy can be performed using robotic surgical systems.     

Robotic-Assisted Hysterectomy for the Management of Severe Endometriosis: A Retrospective Review of Short-Term Surgical Outcomes

Objectives:

The primary objective was to examine the safety and feasibility of robotic-assisted laparoscopy in a cohort of women treated surgically for stage III and IV endometriosis. The secondary objective was to explore whether the stage of endometriosis affected surgical outcome.

Methods:

In this cohort study, 43 women with severe endometriosis were treated with robot-assisted laparoscopic hysterectomy with unilateral or bilateral salpingo-oophorectomy for stage III (n = 19) or stage IV (n = 24) disease.

Results:

Histopathologic evaluation confirmed endometriosis in all patients, and fibroids were also shown in 12 patients. The median actual operative time was 145 min (range, 67–325 min), and the median blood loss was 100 mL (range, 20–400 mL). All but one of the procedures were completed successfully robotically. The length of hospital stay was 1 d for 95% of patients (41 of 43), and 2 patients had prolonged stays of 4 d and 5 d, respectively. One patient was readmitted for a vaginal cuff abscess; this represented the only complication identified in this series.

Conclusions:

Robot-assisted laparoscopic surgery appears to be a reasonably safe and feasible method for the definitive surgical management of women with severe endometriosis.     

A Review of the Current Status of Laparoscopic and Robot-assisted Sacrocolpopexy for Pelvic Organ Prolapse

Context

Abdominal sacrocolpopexy (ASC) represents the superior treatment for apical pelvic organ prolapse (POP) but is associated with increased length of stay, analgesic requirement, and cost compared with transvaginal procedures. Laparoscopic sacrocolpopexy (LSC) and robot-assisted sacrocolpopexy (RSC) may offer shorter postoperative recovery while maintaining equivalent rates of cure.

Objective

This review evaluates the literature on LSC and RSC for clinical outcomes and complications.

Evidence acquisition

A PubMed search of the available literature from 1966 to 2013 on LSC and RSC with a follow-up of at least 12 mo was performed. A total of 256 articles were screened, 69 articles selected, and outcomes from 26 presented. A review, not meta-analysis, was conducted due to the quality of the articles.

Evidence synthesis

LSC has become a mature technique with results from 11 patient series encompassing 1221 patients with a mean follow-up of 26 mo. Mean operative time was 124 min (range: 55–185) with a 3% (range: 0–11%) conversion rate. Objective cure was achieved in 91% of patients, with similar satisfaction rates (92%). Six patient series encompassing 363 patients treated with RSC with a mean follow-up of 28 mo have been reported. Mean operative time was 202 min (range: 161–288) with a 1% (range: 0–4%) conversion rate. Objective cure rate was 94%, with a 95% subjective success rate. Overall, early outcomes and complication rates for both LSC and RSC appeared comparable with open ASC.

Conclusions

LSC and RSC provide excellent short- to medium-term reconstructive outcomes for patients with POP. RSC is more expensive than LSC. Further studies are required to better understand the clinical performance of RSC versus LSC and confirm long-term efficacy.

Patient summary

Laparoscopic and robot-assisted sacrocolpopexy represent attractive minimally invasive alternatives to abdominal sacrocolpopexy. They may offer reduced patient morbidity but are associated with higher costs.     

Comparing the da Vinci Si Single Console and Dual Console in Teaching Novice Surgeons Suturing Techniques

Background and Objectives:

Robot-assisted laparoscopic surgery is often taught with the surgical mentor at the surgeon console and the trainee at the patient''s bedside. The da Vinci dual console (Intuitive Surgical, Sunnyvale, California) allows a surgical mentor to teach with both the mentor and the trainee working at a surgeon console simultaneously. The purpose of this study is to evaluate the effectiveness of the dual console versus the single console for teaching medical students robotic tasks.

Methods:

Forty novice medical students were randomized to either the da Vinci single-console or dual-console group and were taught 4 knot-tying techniques by a surgical mentor. The students were timed while performing the tasks.

Results:

No statistically significant differences in mean task times were observed between the single- and dual-console groups: interrupted stitch with a 2-handed knot (300 seconds for single vs 294 seconds for dual, P = .59), interrupted stitch with a 1-handed knot (198 seconds for single vs 212 seconds for dual, P = .88), figure-of-8 stitch with a 2-handed knot (261 seconds for single vs 219 seconds for dual, P = .20), and figure-of-8 stitch with a 1-handed knot (200 seconds for single vs 199 seconds for dual, P = .53).

Conclusion:

No significant difference was observed in performance time when teaching knot-tying techniques to medical students using the da Vinci dual console compared with the single console. More research needs to be performed on the utility of the da Vinci dual console in surgical training.

Laparoscopy vs Robotics in Surgical Management of Endometrial Cancer: Comparison of Intraoperative and Postoperative Complications

Study ObjectiveTo compare the rates of intraoperative and postoperative complications of robotic surgery and laparoscopy in the surgical treatment of endometrial cancer.DesignUnicentric retrospective study (Canadian Task Force classification II-2).SettingTertiary teaching hospital.PatientsThe study was performed from January 2002 to December 2011 and included patients with endometrial cancer who underwent laparoscopic or robotically assisted laparoscopic surgical treatment. Data collected included preoperative data, tumor characteristics, intraoperative data (route of surgery, surgical procedures, and complications), and postoperative data (early and late complications according to the Clavien-Dindo classification, and length of hospital stay). Morbidity was compared between the 2 groups.Measurements and Main ResultsThe study included 146 patients, of whom 106 underwent laparoscopy and 40 underwent robotically assisted surgery. The 2 groups were comparable in terms of demographic and preoperative data. Intraoperative complications occurred in 9.4% of patients who underwent laparoscopy and in none who underwent robotically assisted surgery (p = .06). There was no difference between the 2 groups in terms of postoperative events.ConclusionRobotically assisted surgery is not associated with a significant difference in intraoperative and postoperative complications, even when there were no intraoperative complications of robotically assisted surgery.
