RESUMEN

STUDY OBJECTIVE: To analyze hysterectomy trends and vaginal cuff dehiscence (VCD) rates by mode of surgery at a tertiary care medical center and to describe characteristics of VCD cases. DESIGN: Observational retrospective cohort study. SETTING: Large academic hospital and affiliated community hospital. PATIENTS: 4722 patients who underwent hysterectomy at Columbia University Irving Medical Center between January 2010 and August 2021. INTERVENTIONS: Current Procedural Terminology and International Classification of Diseases codes identified hysterectomies and VCD cases. Hysterectomy trends and VCD rates were calculated by mode of surgery. Relative risks of VCD for each mode were compared with total abdominal hysterectomy (TAH). Clinical characteristics of VCDs were reviewed. MEASUREMENTS AND MAIN RESULTS: There were 4059 total hysterectomies. Laparoscopic hysterectomies, including total laparoscopic hysterectomies (TLHs), laparoscopic-assisted vaginal hysterectomies, and robot-assisted TLHs (RA-TLHs), increased from 41.9% in 2010 to 65.9% in 2021 (p <.001). RA-TLH increased from 5.7% in 2010 to 40.2% in 2021. Supracervical hysterectomies followed similar trends and were excluded from VCD analysis. There were 15 VCDs (overall rate 0.37%). VCD was highest after RA-TLH (0.66%), followed by TLH (0.32%) and TAH (0.27%), with no VCDs after laparoscopic-assisted vaginal hysterectomy or total vaginal hysterectomy. Compared with TAH, the relative risk for VCD after RA-TLH was 2.44 (95% confidence interval 0.66-9.00) and after TLH was 1.18 (95% confidence interval 0.24-5.83), which were not statistically significant. The mean time to dehiscence was 39 days (range 8-145 days). The most common trigger event was coitus (41%). CONCLUSION: VCD rates were low (<1%) for all modes of hysterectomy, and rates after robotic and laparoscopic hysterectomy were much lower than previously reported. Although VCD rates trended higher after robotic and laparoscopic hysterectomy compared with abdominal hysterectomy, the difference was not significant. It is difficult to determine whether this finding represents true lack of difference vs a lack of power to detect a significant difference given the rarity of VCD.

RESUMEN

OBJECTIVE: To evaluate the perioperative morbidity and mortality of patients with COVID-19 who undergo urgent and emergent surgery. SUMMARY BACKGROUND DATA: Although COVID-19 infection is usually associated with mild disease, it can lead to severe respiratory complications. Little is known about the perioperative outcomes of patients with COVID-19. METHODS: We examined patients who underwent urgent and emergent surgery at 2 hospitals in New York City from March 17 to April 15, 2020. Elective surgical procedures were cancelled throughout and routine, laboratory based COVID-19 screening was instituted on April 1. Mortality, complications, and admission to the intensive care unit were compared between patients with COVID-19 detected perioperatively and controls. RESULTS: Among 468 subjects, 36 (7.7%) had confirmed COVID-19. Among those with COVID-19, 55.6% were detected preoperatively and 44.4% postoperatively. Before the routine preoperative COVID-19 laboratory screening, 7.7% of cases were diagnosed preoperatively compared to 65.2% after institution of screening (P = 0.0008). The perioperative mortality rate was 16.7% in those with COVID-19 compared to 1.4% in COVID-19 negative subjects [aRR = 9.29; 95% confidence interval (CI), 5.68-15.21]. Serious complications were identified in 58.3% of COVID-19 subjects versus 6.0% of controls (aRR = 7.02; 95%CI, 4.96-9.92). Cardiac arrest, sepsis/shock, respiratory failure, pneumonia, acute respiratory distress syndrome, and acute kidney injury were more common in those with COVID-19. The intensive care unit admission rate was 36.1% in those with COVID-19 compared to 16.4% of controls (aRR = 1.34; 95%CI, 0.86-2.09). CONCLUSIONS: COVID-19 is associated with an increased risk for serious perioperative morbidity and mortality. A substantial number of patients with COVID-19 are not identified until after surgery.

RESUMEN

STUDY OBJECTIVE: The purpose of this study was to assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on surgical volume and emergency department (ED) consults across obstetrics-gynecology (OB-GYN) services at a New York City hospital. DESIGN: Retrospective cohort study. SETTING: Tertiary care academic medical center in New York City. PATIENTS: Women undergoing OB-GYN ED consults or surgeries between February 1, 2020 and April 15, 2020. INTERVENTIONS: March 16 institutional moratorium on elective surgeries. MEASUREMENTS AND MAIN RESULTS: The volume and types of surgeries and ED consults were compared before and after the COVID-19 moratorium. During the pandemic, the average weekly volume of ED consults and gynecology (GYN) surgeries decreased, whereas obstetric (OB) surgeries remained stable. The proportions of OB-GYN ED consults, GYN surgeries, and OB surgeries relative to all ED consults, all surgeries, and all labor and delivery patients were 1.87%, 13.8%, 54.6% in the pre-COVID-19 time frame (February 1-March 15) vs 1.53%, 21.3%, 79.7% in the COVID-19 time frame (March 16-April 15), representing no significant difference in proportions of OB-GYN ED consults (p = .464) and GYN surgeries (p = .310) before and during COVID-19, with a proportionate increase in OB surgeries (p <.002). The distribution of GYN surgical case types changed significantly during the pandemic with higher proportions of emergent surgeries for ectopic pregnancies, miscarriages, and concern for cancer (p <.001). Alternatively, the OB surgery distribution of case types remained relatively constant. CONCLUSION: This study highlights how the pandemic has affected the ways that patients in OB-GYN access and receive care. Institutional policies suspending elective surgeries during the pandemic decreased GYN surgical volume and affected the types of cases performed. This decrease was not appreciated for OB surgical volume, reflecting the nonelective and time-sensitive nature of obstetric care. A decrease in ED consults was noted during the pandemic begging the question "Where have all the emergencies gone?" Although the moratorium on elective procedures was necessary, "elective" GYN surgeries remain medically indicated to address symptoms such as pain and bleeding and to prevent serious medical sequelae such as severe anemia requiring transfusion. As we continue to battle COVID-19, we must not lose sight of those patients whose care has been deferred.

RESUMEN

STUDY OBJECTIVE: The primary objective was to compare carbon dioxide (CO2) absorption rates in patients undergoing gynecologic laparoscopy with a standard versus valveless insufflation system (AirSeal; ConMed, Utica, NY) at intra-abdominal pressures (IAPs) of 10 and 15 mm Hg. Secondary objectives were assessment of surgeons' visualization of the operative field, anesthesiologists' ability to maintain adequate end-tidal CO2 (etCO2), and patients' report of postoperative shoulder pain. DESIGN: A randomized controlled trial using an equal allocation ratio into 4 arms: standard insufflation/IAP 10 mm Hg, standard insufflation/IAP 15 mm Hg, valveless insufflation/IAP 10 mm Hg, and valveless insufflation/IAP 15 mm Hg. SETTING: Single tertiary care academic institution. PATIENTS: Women ≥ 18 years old undergoing nonemergent conventional or robotic gynecologic laparoscopic surgery. INTERVENTIONS: A standard or valveless insufflation system at IAPs of 10 or 15 mm Hg. MEASUREMENTS AND MAIN RESULTS: One hundred thirty-two patients were enrolled and randomized with 33 patients per group. There were 84 robotic cases and 47 conventional laparoscopic cases. CO2 absorption rates (mL/kg*min) did not differ across groups with mean rates of 4.00 ± 1.3 in the valveless insufflation groups and 4.00 ± 1.1 in the standard insufflation groups. The surgeons' rating of overall visualization of the operative field on a 10-point Likert scale favored the valveless insufflation system (median visualization, 9.0 ± 2.0 cm and 9.5 ± 1.8 cm at 10 and 15 mm Hg, respectively) over standard insufflation (7.0 ± 3.0 cm and 7.0 ± 2.0 cm at 10 and 15 mm Hg, respectively; p <.001). The anesthesiologists' ability to maintain adequate etCO2 was similar across groups (p = .417). Postoperative shoulder pain scores were low overall with no significant difference across groups (p >.05). CONCLUSION: CO2 absorption rates, anesthesiologists' ability to maintain adequate etCO2, and postoperative shoulder pain did not differ based on insufflation system type or IAP. Surgeons' rating of visualization of the operative field was significantly improved when using the valveless over the standard insufflation system.

RESUMEN

STUDY OBJECTIVE: To evaluate the Essentials in Minimally Invasive Gynecology (EMIG)- Fundamentals of Laparoscopic Surgery Laparoscopic Simulation System and the EMIG Hysteroscopy Simulation System for face validity and functionality in a pilot testing environment. DESIGN: A prospective controlled pilot study. SETTING: Three teaching institutions in the US Southwest. SUBJECTS: Twenty-seven residents and gynecologists, with 22 fitting who fit 1 of 4 categories of exposure to hysteroscopic and laparoscopic surgery and surgical simulation. Eleven were postgraduate year 1 and 5 postgraduate year 3, 1 was American Board of Obstetrics & Gynecology certified, and 5 were either fellows in-training or had completed a fellowship in minimally invasive gynecologic surgery. INTERVENTIONS: After completing a screening survey, each subject was exposed to a structured orientation to the 2 simulation systems and then tested with proctor supervision on the 5 laparoscopic and 2 hysteroscopic exercises. A short 5-point Likert questionnaire designed to determine face validation and question clarity was administered to each subject at sites 2 and 3. MEASUREMENTS AND MAIN RESULTS: Face validity was high for each of the 7 exercises (means ranged from 4.8 to 4.9 of 5), and subjects considered instructions to be clear (means from 4.7 to 4.9). The recorded exercise times generally reduced with increasing levels of training, although the sample sizes were not designed to determine significance given the pilot design. Similarly, exercise errors were generally less frequent with increasing experience. The systems, including the devices and recording mechanisms, performed well, and proctor evaluation and training were satisfactory. CONCLUSION: The EMIG laparoscopic and hysteroscopic simulations systems were considered to have good face validity and appear to be suitable for a construct validation trial to confirm their utility in distinguishing among trainees and practitioners with a wide spectrum of endoscopic surgical experience. The recording and specimen storage mechanisms will allow for multiple proctors to rate a candidate's performance, thereby enhancing evaluation consistency and quality.

RESUMEN

PURPOSE OF REVIEW: This review highlights the complexity of caring for gynecologic patients who refuse blood transfusion and discusses the importance of early, targeted perioperative and intraoperative medical optimization. We review alternative interventions and the importance of medical management to minimize blood loss and maximize hematopoiesis, particularly in gynecologic patients who may have significant uterine bleeding. The review also focuses on intraoperative interventions and surgical techniques to prevent and control surgical blood loss. RECENT FINDINGS: With improvements in surgical technique, greater availability of minimally invasive surgery, and increased use of preop UAE and cell salvage, definitive surgical management can be safely performed. New technologies have been developed that allow for safer surgeries or alternatives to traditional surgical procedures. Many medical therapies have been shown to decrease blood loss and improve surgical outcomes. Nonsurgical interventions have also been developed for use as adjuncts or alternatives to surgery. SUMMARY: The care of a patient who declines blood transfusion may be complex, but gynecologic surgeons can safely and successfully offer a wide variety of therapies depending on the patient's goals and needs. Medical management should be implemented early. A multidisciplinary team should be mobilized to provide comprehensive and patient-centered care.

RESUMEN

BACKGROUND: Many gynecologic, urologic, and pelvic reconstructive surgeries require accurate intraoperative evaluation of ureteral patency. OBJECTIVE: We performed a randomized controlled trial to compare surgeon satisfaction with 4 methods of evaluating ureteral patency during cystoscopy at the time of benign gynecologic or pelvic reconstructive surgery: oral phenazopyridine, intravenous sodium fluorescein, mannitol bladder distention, and normal saline bladder distention. STUDY DESIGN: We conducted an unblinded randomized controlled trial of the method used to evaluate ureteral patency during cystoscopy at time of benign gynecologic or pelvic reconstructive surgery. Subjects were randomized to receive 200 mg oral phenazopyridine, 25 mg intravenous sodium fluorescein, mannitol bladder distention, or normal saline bladder distention during cystoscopy. The primary outcome was surgeon satisfaction with the method, assessed via a 100-mm visual analog scale with 0 indicating strong agreement and 100 indicating strong disagreement with the statement. Secondary outcomes included comparing visual analog scale responses about ease of each method and visualization of ureteral jets, bladder mucosa and urethra, and operative information, including time to surgeon confidence in the ureteral jets. Adverse events were evaluated for at least 6 weeks after the surgical procedure, and through the end of the study. All statistical analyses were based on the intent-to-treat principle, and comparisons were 2-tailed. RESULTS: In all, 130 subjects were randomized to phenazopyridine (n = 33), sodium fluorescein (n = 32), mannitol (n = 32), or normal saline (n = 33). At randomization, patient characteristics were similar across groups. With regard to the primary outcome, mannitol was the method that physicians found most satisfactory on a visual analog scale. The median (range) scores for physicians assessing ureteral patency were 48 (0-83), 20 (0-82), 0 (0-44), and 23 (3-96) mm for phenazopyridine, sodium fluorescein, mannitol, and normal saline, respectively (P < .001). Surgery length, cystoscopy length, and time to surgeon confidence in visualization of ureteral jets were not different across the 4 randomized groups. During the 189-day follow-up, no differences in adverse events were seen among the groups, including urinary tract infections. CONCLUSION: The use of mannitol during cystoscopy to assess ureteral patency provided surgeons with the most overall satisfaction, ease of use, and superior visualization without affecting surgery or cystoscopy times. There were no differences in adverse events, including incidence of urinary tract infections.

RESUMEN

The Robotic Objective Structured Assessment of Technical Skills (R-OSATS) is a previously validated assessment tool that is used to assess 5 standardized inanimate robotic surgery drills. R-OSATS is used to evaluate performance on surgical drills, with scores of 0 to 20 for each drill. Our objective was to establish the minimum threshold score that denotes competence on these drills. Thus, we performed a standard setting study using data from surgeons and trainees in 8 academic medical centers. Cutoff scores for the minimal level of competence using R-OSATS were established using 2 techniques: the modified Angoff and the contrasting groups methods. For the modified Angoff method, 8 content experts met and, in an iterative process, derived the scores that a minimally competent trainee should receive. After 2 iterative rounds of scoring and discussion with the modified Angoff method, we established a minimum competence score per drill with high agreement (rWG range, 0.92-0.98). There was unanimous consensus that a trainee needs to achieve competence on each independent drill. A second method, the contrasting groups method, was used to verify our results. In this method, we compared R-OSATS scores from "inexperienced" (34 postgraduate year 1 and 2 trainees) with "experienced" (22 faculty and fellow) robotic surgeons. The distributions of scores from both groups were plotted, and a cutoff score for each drill was determined from the intersection of the 2 curves. Using this method, the minimum score for competence would be 14 per drill, which is slightly more stringent but confirms the results obtained from the modified Angoff approach. In conclusion, using 2 well-described standard setting techniques, we have established minimum benchmarks designating trainee competence for 5 dry lab robotic surgery drills.

RESUMEN

PURPOSE: To compare the frequency of minimally invasive surgical approach to hysterectomy between two time periods, during which the use of the robotic technique has rapidly increased. METHODS: This study is a retrospective review of 623 consecutive patients who underwent hysterectomy for benign indications at the Division of Minimally Invasive Gynecologic Surgery via laparoscopic, robotic, laparotomy, mini-laparotomy and vaginal approaches from July 2004 to June 2010. "Early period" refers to the first 311 patients, and "late period" refers to the remaining 312 patients. RESULTS: The characteristics of patients from the early and late periods were comparable in terms of age, BMI and uterine weight. The rates of hysterectomy by laparotomy, traditional laparoscopy, robotic, vaginal, and mini-laparotomy were significantly different between the early and late periods (17.7 to 5.4%, 39.5 to 17.6%, 23.8 to 64.1%, 5.8 to 4.8% and 13.2 to 8%, respectively, P < 0.01), with the overall rates of hysterectomies completed via a minimally invasive approach increasing from 82.3 to 94.6%, respectively (P < 0.01). There were no differences in surgical complications between the two periods. CONCLUSION: Increased utilization of a robotic approach to hysterectomy correlates with decreasing rates of abdominal hysterectomy concurrent with decreasing rates of traditional laparoscopic hysterectomy. This shift in surgical approach to hysterectomy, while beneficial in increasing the rates of minimally invasive approach to hysterectomy, may have significant economic implications due to the higher cost of robotic surgery.

RESUMEN

Laparoscopic surgery has revolutionized the manner in which many operations are performed today. The volume of tissue to be removed during some operations can be a limiting factor for laparoscopy and is frequently a reason for converting from a minimally invasive laparoscopic surgical approach to the conventional open surgical approach. The introduction of the electronic morcellator has helped facilitate the removal of large specimens via minimally invasive surgery. The purpose of this study is to evaluate the effectiveness of the Gynecare Morcellex® morcellator (Ethicon, Inc., Somerville, NJ), the MOREsolution™ morcellator (Blue Endo, Lenexa, Kansas), and the Rotocut™ G1 morcellator (Karl Storz, Tuttlingen, Germany) tissue morcellators based upon their ease of use and efficacy in a simulation setting among an unbiased cohort of novice surgeons. University of Central Florida College of Medicine students were observed using the three different morcellators in a randomized order on 250 g beef tissue models and were surveyed on the ease of use of the morcellators. The MOREsolution™ tissue morcellator demonstrated significantly faster tissue morcellation times (544.6 ± 123.0 sec) and produced a higher number of long tissue fragments (7.44 ± 0.683) compared to the Rotocut™ G1 morcellators' time (609.7 ± 153.2 sec) and number of long tissue fragments (6.00 ± 0.638). No significant differences were found between the Gynecare Morcellex® and other morcellators in the total number of fragments obtained nor study participant opinion on the ease of use of the three morcellators. This study demonstrates that the MOREsolution™ morcellator is a faster morcellator and produces larger tissue fragments as compared to the Rotocut™ G1; however, more studies should be performed to confirm these findings in a clinical setting.

RESUMEN

The worldwide growth of robot-assisted laparoscopic surgery has been exponential since its FDA approval for use in gynecologic surgery in the spring of 2005. This growth has spanned the entire gamut of gynecologic procedures and pathology. One area that has leveraged the unique aspects of robotics has been its application to the conservative surgical management of uterine fibroids. This manuscript will review the surgical technique and highlight the current situation regarding the scientific literature with an evidence-based focus on the role of robot-assisted laparoscopic myomectomy (RALM) with the daVinci Surgical System (Intuitive Surgical, Sunnyvale, CA).

RESUMEN

A successful pregnancy relies on the proper cellular, biochemical, and mechanical functions of the uterus. A comprehensive understanding of uterine mechanical properties during pregnancy is key to understanding different gynecological and obstetric disorders such as preterm birth, placenta accreta, leiomyoma, and endometriosis. This study sought to characterize the macro-scale equilibrium material behaviors of the human uterus in non-pregnancy and late pregnancy under both compressive and tensile loading. Fifty human uterine specimens from 16 patients (8 nonpregnant [NP] and 8 pregnant [PG]) were tested using spherical indentation and uniaxial tension coupled with digital image correlation (DIC). A three-level incremental load-hold protocol was applied to both tests. A microstructurally-inspired material model considering fiber architecture was applied to this dataset. Inverse finite element analysis (IFEA) was then performed to generate a single set of mechanical parameters to describe compressive and tensile behaviors. The freeze-thaw effect on uterine macro mechanical properties was also evaluated. PG tissue exhibits decreased overall stiffness and increased fiber network extensibility compared to NP uterine tissue. Under indentation, ground substance compressibility was similar between NP and PG uterine tissue. In tension, the fiber network of the PG uterus was found to be more extensible and dispersed than in nonpregnancy. Lastly, a single freeze-thaw cycle did not systematically alter the macro-scale material behavior of the human uterus.

RESUMEN

BACKGROUND AND OBJECTIVES: We compared the perioperative outcomes of hysterectomy performed by robotic (RH) versus laparoscopic (LH) routes for benign indications using the Dindo-Clavien scale for classification of the surgical complications. METHODS: Retrospective chart review of all patients who underwent robotic (n=288) and laparoscopic (n=257) hysterectomies by minimally invasive surgeons at the University of Michigan from March 2001 until June 2010. RESULTS: Age, body mass index, operative time, and estimated blood loss were not statistically different between groups. The RH subgroup had a larger uterine weight (LH 186.4±130.6 g vs RH 234.9±193.9 g, P=.001), higher prevalence of severe adhesions (13.2% vs 23.3%, respectively, P=.003), and stage III-IV endometriosis (4.7% vs 15.3%, respectively, P<.05). There were no differences in the rates of Dindo-Clavien grade I, grade II, and grade III surgical complications between the RH and LH groups (9.7%, 13.2%, and 3.1%, respectively, in the RH group vs 6.2%, 9.3%, and 5.8%, respectively, in the LH group, P>.05). However, the rates of urinary tract infection were higher in the RH group (LH 2.7% vs RH 6.9%, P=.02), whereas the conversion to laparotomy rate was higher in the LH group (LH 6.2% vs RH 1.7%, P=.007). CONCLUSIONS: Perioperative outcomes for laparoscopic and robotic hysterectomy for benign indications appear to be equivalent.

RESUMEN

BACKGROUND AND OBJECTIVE: Deep infiltrating pelvic endometriosis with bowel involvement is one of the most aggressive forms of endometriosis. Nowadays, robotic technology and telemanipulation systems represent the latest developments in minimally invasive surgery. The aim of this study is to present our preliminary results and evaluate the feasibility of robotic-assisted laparoscopic colorectal resection for severe endometriosis. METHODS: Between September 2009 and December 2011, 10 women with colorectal endometriosis underwent surgery with the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA, USA). We evaluated the following parameters: short-term complications, clinical outcomes and long-term follow-up, pain relief recurrence rate, and fertility outcomes. RESULTS: Extensive ureterolysis was required in 8 women (80%). Ovarian cystectomy with removal of the cystic wall was performed in 7 women (70%). Torus resection was performed in all women, with unilateral and bilateral uterosacral ligament resection in 1 woman (10%) and 8 women (80%), respectively. In addition to segmental colorectal resection in all cases, partial vaginal resection was necessary in 2 women (20%). An appendectomy was performed in 2 patients (20%). The mean operative time with the robot was 157 minutes (range, 90-190 minutes). The mean hospital stay was 3 days. Six patients had infertility before surgery, with a mean infertility time of 2 years. After a 12-month follow-up period, 4 women (67%) conceived naturally and 2 (33%) underwent in vitro fertilization. CONCLUSION: We show that robotic-assisted laparoscopic surgery for the treatment of deep infiltrating bowel endometriosis is feasible, effective, and safe.

RESUMEN

INTRODUCTION: Chronic Pelvic Pain (CPP) is a complex, multifaceted condition that affects both women and men. There is limited literature on the cost utilization the healthcare system and CPP patients incur. The purpose of this analysis is to characterize the overall healthcare utilization, cost burden, and quality-of-life restrictions experienced by CPP patients using data from an outpatient pelvic rehabilitation practice. METHODS: Healthcare utilization data was gathered by systematically reviewing and analyzing data from new patient visit progress notes stored in the clinic's electronic health records (EHR). We obtained in-network costs by using the FAIR Health Consumer online database. Overall costs were then calculated as the utilization times the per-unit costs from the FAIR database. Additionally, data on patients' visual analogue scale (VAS), absenteeism, presenteeism emergency room visits, usage of common pain medications, use of diagnostics, and participation in common treatment modalities was gathered. RESULTS: Data from 607 patients was used. The overall cost burden per patient for all surgeries combined was $15,750 for in-network services. The cost burden for diagnostics was $5,264.22 and treatments was $8,937 per patient for in-network treatments. CONCLUSION: Chronic Pelvic Pain was found to have a large cost burden of $29,951 for in-network services which includes treatments, diagnostics, and surgeries. This analysis sets the stage for future investigations involving data on costs of medications that patients have tried prior to presenting to us and costs associated with work hours lost.

RESUMEN

As technology has evolved, so has the ability to perform a hysterectomy in a minimallly invasive fashion. Currently, total laparoscopic hysterectomy has been further advanced with the advent of uterine manipulation devices that incorporate the use of a cupped colpotomizer. Unfortunately, many gynecologic surgeons lack the understanding of how to fully utilize such a surgical guide to facilitate development of the vesico-uterine reflection, skeletonize uterine vasculature, gain entry into the vagina, and subsequently close the vaginal cuff. Safe completion of these steps has the potential to minimize complications such as ureteral and bladder injury in addition to vaginal cuff dehiscence. The following technical review will address methods for the safe and effective use of various cupped colpotomizer devices during total laparoscopic hysterectomy.

RESUMEN

• Urogynaecology is a subspecialty practiced by both urologists and gynaecologists specialised in treating women with pelvic floor disorders and urinary incontinence. • While urogynaecology covers a vast range of disorders, two disorders frequently managed by urogynaecologists are pelvic organ prolapse (POP) and pelvic fistulae. • Surgical intervention is often the treatment option for both POP and pelvic fistulae after all conservative options have been attempted. The daVinci Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA, USA) has applications for the minimally invasive surgical management of POP and pelvic fistulas. • The following review will address the development and current state of robotic assistance in treating these disorders.
