Adenomyosis and infertility.

PURPOSE: Adenomyosis is a poorly understood entity with no unified treatment protocol. It has been thought to only affect the quality of life of older women, but growing evidence is highlighting the increased frequency of adenomyosis in younger patients and its possible effects on fertility outcomes. This can have a great impact on how clinicians screen, diagnose, and treat this condition. The aim of this review is to explore the relationship between adenomyosis and infertility. METHODS: A literature search of the keywords "adenomyosis", "infertility", "pregnancy" and "fertility" was conducted using the PubMed and Medline search engines. The articles selected were observational, systematic reviews, meta-analyses, and randomized controlled trials. The search was limited to English, abstracts were screened, and articles were selected. RESULTS: The literature reports lower clinical pregnancy rates, lower live birth rates, higher miscarriage rates, and higher odds of adverse obstetric outcomes in patients with adenomyosis. Treatment seems to be associated with higher pregnancy rates and live births rates. CONCLUSION: An association between adenomyosis and infertility seems to exist, and treatment could lead to improved fertility outcomes.

Virtual postoperative visits following robotic gynecologic surgery: a study of patient satisfaction, safety, and feasibility.

Since the onset of the COVID-19 pandemic the use of telehealth has burgeoned. Numerous surgical specialties have already adopted the use of virtual postoperative visits, but there is data lacking in both robotics and gynecology. In this single-institution prospective cohort study we sought to evaluate the patient satisfaction, feasibility and safety of postoperative telehealth visits following robotic gynecologic surgery. Thirty-three patients undergoing robotic gynecologic procedures participated in a postoperative telehealth visit approximately 2 weeks following surgery, of which 27 completed a survey which assessed participant satisfaction with the telehealth visit, overall health-related quality of life following surgery, exposure to telehealth visits, and social determinants of health. The mean satisfaction score was just below 'excellent'. Only 2 participants (6.3%) required an in-person visit. Postoperative telehealth visit satisfaction score was significantly associated only with BMI (Pearson r = 0.45, p = 0.018). These data suggest that telehealth visits following robotic gynecologic procedures appear to be safe and feasible, and are associated with a high level of patient satisfaction.

Diaphragmatic endometriosis and thoracic endometriosis syndrome: a review on diagnosis and treatment.

Endometriosis of the diaphragm has been gaining more attention in the practice of gynecologists and thoracic surgeons in recent years. Understanding related symptoms and developing imaging methods have improved their approach. A review of the literature was performed with the aim to report on incidence, diagnosis, treatment and prognosis of diaphragmatic endometriosis. We also cover the issue of the Thoracic Endometriosis Syndrome (TES). Complaints of cyclic chest pain in patients of childbearing age should have as differential diagnosis the presence of thoracic endometriosis. Catamenial pneumothorax is the main manifestation of diaphragmatic endometriosis and Thoracic Endometriosis Syndrome. Other possible manifestations are hemothorax, pulmonary nodules, and diaphragmatic hernia. Despite the possibility of drug treatment, many patients will be submitted to surgical treatment. The minimally invasive approach should be the one of choice. The robotic pathway allows for an easier approach due to its ability to articulate robotic arms, allowing the treatment of lesions in hard-to-reach locations, such as the posterior part of the diaphragm. Multidisciplinary treatment should be used in most cases, as only abdominal approach is not sufficient for the diagnosis and treatment of lesions in the thoracic cavity. The approach of endometriosis of the diaphragm and Thoracic Endometriosis Syndrome should be multidisciplinary, allowing the improvement of quality of life in most patients.

Current and Prospective Treatment of Adenomyosis.

(1) Background: Adenomyosis is a poorly understood entity which makes it difficult to standardize treatment. In this paper we review and compare the currently approved medical and surgical treatments of adenomyosis and present the evidence behind them. (2) Methods: A PubMed search was conducted to identify papers related to the different treatments of adenomyosis. The search was limited to the English language. Articles were divided into medical and surgical treatments. (3) Results: Several treatment options have been studied and were found to be effective in the treatment of adenomyosis. (4) Conclusions: Further randomized controlled trials are needed to compare treatment modalities and establish a uniform treatment algorithm for adenomyosis.

Patterns of narcotic utilization in women undergoing hysterectomy for benign indications.

OBJECTIVE: To determine whether perioperative narcotic utilization at the time of hysterectomy has decreased since 2012. STUDY DESIGN: Retrospective cohort study. SETTING: Academic university hospital. PATIENTS: Patients who underwent a laparoscopic hysterectomy for benign indications between January 2012 and December 2018. INTERVENTIONS: Perioperative narcotics administration. MEASUREMENTS AND MAIN RESULTS: We identified 651 patients who underwent a hysterectomy for benign indications from 2012 to 2018. Of these, 377 surgeries were performed using robotic-assistance (58%) and the remainder (42%) were performed by conventional laparoscopy. Narcotic utilization declined significantly by year for both intra-operative and post-operative periods (both p<.001). The largest decline for intraoperative morphine milligram equivalents (MME) was between 2016 and 2017, while for post-operative MME, it was between 2012 and 2013. The pattern remained significant after adjusting for covariates. Intraoperative MME administration was correlated with postoperative MME use (Spearman r = 0.23, p<.001). Of the demographic variables only Body Mass Index was significantly associated with perioperative narcotic administration. CONCLUSION: Administration of opioids for intraoperative and postoperative pain after minimally invasive hysterectomy substantially decreased from 2012 to 2018. Intraoperative narcotic utilization was correlated with immediate postoperative narcotic consumption. Heightened awareness of opioid administration practices during and immediately following surgery is critically important to decreasing risk of chronic opioid dependence and providing the best possible care for the patients we serve.

Patterns of voiding following laparoscopic hysterectomy.

OBJECTIVE: Clarify the normal patterns of voiding after minimally invasive hysterectomy. We also aim to identify perioperative factors associated with delayed time to void immediately following hysterectomy. DESIGN: Retrospective cohort study SELECTION: Women undergoing laparoscopic hysterectomy between September 2012 to October 2018 at a single academic university hospital. RESULTS: 450 minimally invasive hysterectomies were included in the final analysis, 274 (60.9%) robotically-assisted, and 176 (39.1%) conventional laparoscopy. The overall median postoperative time-to-void following a retrograde bladder filling of 150 mL normal saline was 179 min. Based on the 50th percentile of the distribution of the time-to-void, two groups were created. Demographic characteristics between the groups were similar, except those who were above the 50th percentile were more likely to be older, have a reported history of previous myomectomy, and had a longer postoperative PACU stay compared to those below or equal to the 50th percentile. The mean time-to-void following conventional laparoscopic hysterectomy was less than that of robotic surgery (187.3 vs 200.5 min) however the difference was not statistically significant (p=.22). The use of hydromorphone intraoperatively and the combination of oxycodone-acetaminophen postoperatively were more likely to be associated with the group of patients above the 50th percentile but there was no significant difference in perioperative utilization of median morphine milliequivalents (MME) between the two groups. CONCLUSIONS: Following laparoscopic hysterectomy (either conventional or with robotic-assistance) with a retrograde bladder fill of 150 mL normal saline most patients will void within 4 h after surgery. This is consistent with historic data on normal voiding patterns facilitating safe same day discharge without prolonged time in the PACU.

A narrative review of functional outcomes following nerve-sparing surgery for deeply infiltrating endometriosis.

Endometriosis negatively impacts the lives of countless women around the world. When medical management fails to improve the quality of life for women with either previously confirmed or suspected endometriosis often a decision must be made whether or not to proceed with surgery. When deeply infiltrating disease is diagnosed either clinically or by imaging studies often medical management alone will not suffice without excisional surgery. Surgery for endometriosis, especially deeply infiltrating disease, is not without risks. Aside from common risks of surgery endometriosis may also involve pelvic nerves, which can be hard to recognize to the untrained eye. Identification of pelvic nerves commonly encountered during endometriosis surgery is paramount to avoid inadvertent injury to optimize function outcomes. Injury to pelvic nerves can lead to urinary retention, constipation, sexual dysfunction, and refractory pain. However, nerve-sparing surgery for endometriosis has been proven to mitigate these complications and enhance recovery following surgery. Here we review the benefits of nerve-sparing surgery for deeply infiltrating disease.

A Clinically Applicable Prediction Model for the Risk of Transfusion in Women Undergoing Myomectomy.

STUDY OBJECTIVE: We sought to identify the variables independently associated with intra/postoperative blood transfusion at the time of myomectomy. We further hoped to develop an accurate prediction model using preoperative variables to categorize an individual's risk of blood transfusion during myomectomy. DESIGN: Case-control study. SETTING: Not applicable to this study, which used the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. PATIENTS: Women who underwent an open/abdominal or laparoscopic (robotic or conventional) myomectomy between 2014 and 2017 at participating ACS-NSQIP sites. INTERVENTION: The primary dependent variable was occurrence of intra/postoperative bleeding requiring blood transfusion. Patient demographics, clinical characteristics, preoperative comorbidities, intraoperative variables, and additional 30-day postoperative outcomes were compared at the bivariable level. For the prediction-model development, only variables that can be reasonably known before surgery were included. Variables associated with intra/postoperative bleeding were entered into 2 separate multivariable logistic regression models. Validation of our prediction model was performed internally using 250 bootstrapped iterations of 50% subsamples drawn from the overall population of myomectomy cases from the ACS-NSQIP database. MEASUREMENTS AND MAIN RESULTS: We identified 6387 myomectomies performed during the defined study period. The most common race in our population was black/African American (45.7%), and most of the patients (57.5%) received an open/abdominal route of myomectomy. A total of 623 patients who underwent myomectomy (9.8%) experienced intraoperative/postoperative bleeding with a need for blood transfusion. At the bivariable level, we identified several variables independently associated with the need for blood transfusion at the time of myomectomy. In using only those variables that can be reasonably known before surgery to develop our prediction model, additional multivariable logistic regression elucidated black race, need for preoperative blood transfusion, planned abdominal/open route of surgery, and preoperative hematocrit value as independently associated with blood transfusion. CONCLUSION: We identified a number of perioperative variables associated with intraoperative or postoperative bleeding requiring blood transfusion at the time of myomectomy. We subsequently created a model that accurately predicts individual bleeding risk from myomectomy, using variables that are reasonably apparent preoperatively. Making this prediction model clinically available to gynecologic surgeons will serve to improve the care of women undergoing myomectomy.

A narrative review of platelet-rich plasma (PRP) in reproductive medicine.

PURPOSE: Platelet-rich plasma (PRP) has become a novel treatment in various aspects of medicine including orthopedics, cardiothoracic surgery, plastic surgery, dermatology, dentistry, and diabetic wound healing. PRP is now starting to become an area of interest in reproductive medicine more specifically focusing on infertility. Poor ovarian reserve, menopause, premature ovarian failure, and thin endometrium have been the main areas of research. The aim of this article is to review the existing literature on the effects of autologous PRP in reproductive medicine providing a summation of the current studies and assessing the need for additional research. METHODS: A literature search is performed using PubMed, MEDLINE, and CINAHL Plus to identify studies focusing on the use of PRP therapy in reproductive medicine. Articles were divided into 3 categories: PRP in thin lining, PRP in poor ovarian reserve, and PRP in recurrent implantation failure. RESULTS: In women with thin endometrium, the literature shows an increase in endometrial thickness and increase in chemical and clinical pregnancy rates following autologous PRP therapy. In women with poor ovarian reserve, autologous intraovarian PRP therapy increased anti-Mullerian hormone (AMH) levels and decreased follicle-stimulating hormone (FSH), with a trend toward increasing clinical and live birth rates. This trend was also noted in women with recurrent implantation failure. CONCLUSIONS: Limited literature shows promise in increasing endometrial thickness, increasing AMH, and decreasing FSH levels, as well as increasing chemical and clinical pregnancy rates. The lack of standardization of PRP preparation along with the lack of large randomized controlled trials needs to be addressed in future studies. Until definitive large RCTs are available, PRP use should be considered experimental.

Rates of anastomotic leak and fistula following surgical management of bowel endometriosis: a comparison of shaving, discoid excision, and segmental resection.

Endometriosis is a complex chronic inflammatory condition that can create a multitude of bothersome painful symptoms for women. Bowel endometriosis is often misdiagnosed or overlooked leading to years of suffering for many women. The surgical management of bowel endometriosis varies based on extent of disease as well as surgeon experience. Surgical treatment for bowel endometriosis is complex and a variety of intraoperative and postoperative complications must be considered. Two significant postoperative complications for bowel endometriosis include anastomotic leak and fistula formation. There is continued debate regarding the appropriate surgical treatment for bowel endometriosis. Aggressive surgery with segmental bowel resection is being utilized more cautiously, with an increase in less aggressive shaving or disc excision techniques. Historic beliefs regarding the limitations of shaving and disc excision are being challenged, and with a reduction in morbidity these less aggressive techniques are winning favor among gynecologic surgeons. Shaving, discoid excision, and segmental bowel resection are all feasible surgical management options for bowel endometriosis. Segmental resection is associated with the highest rates of both anastomotic leak and fistula formation, while shaving is associated with the lowest.

Appropriate surgical management of ovarian endometrioma: excision or drainage?

Endometriosis negatively impacts the lives of countless women around the world. When medical management fails to improve quality of life often women are left making a decision whether or not to proceed with surgery. With endometriomas, patient's surgical options include complete surgical removal or drainage via laparoscopy. Here, we review the literature to discuss both techniques, excision and drainage of endometriomas, and what the research supports for endometrioma management.

Safety and feasibility of the three-port robot-assisted hysterectomy across uterine weights.

One strategy thought to reduce direct costs associated with robotic surgery is minimizing the number of robotic arms used for a surgery. We aim to demonstrate the safety and feasibility of the three-port robot-assisted hysterectomy across uterine weights. Retrospective cohort study in a tertiary care university hospital of consecutive patients undergoing a three-port robot-assisted hysterectomy for benign indications. All surgeries were performed between 2012 and 2018 by fellowship-trained minimally invasive gynecologic surgeons. Data from 232 patients were collected. Eighty-eight (37.9%) patients had a uterine weight < 250 g, 63 (27.2%) had a uterine weight between 250 and 500 g, 51 (22.0%) had a uterine weight between 500 and 1000 g, and 30 (12.9%) had a uterine weight ≥ 1000 g. Multivariable regression analysis revealed no statistically significant differences between uterine weight groups and time spent in PACU, the total length of hospital stay, or direct cost. When setting the < 250 g as referent, patients with uterine weights between 500 and 1000 g, and more than 1000 g had an operative time that was on average 23.4% and 91.6% longer than patients with uterine weight < 250 g, respectively (p < 0.01). Patients with uterine weights between 500 and 1000 g and more than 1000 g had an EBL that was on average 35% and 156% higher than patients with uterine weight < 250 g, respectively (p < 0.01). Our data support the safety and feasibility of the three-port robot-assisted hysterectomy technique across uterine weights.

Reliability and Validity of 2 Surgical Prioritization Systems for Reinstating Nonemergent Benign Gynecologic Surgery during the COVID-19 Pandemic.

STUDY OBJECTIVE: Scientifically evaluate the validity and reproducibility of 2 novel surgical triaging systems, as well as offer modifications to the Medically-Necessary, Time-Sensitive (MeNTS) criteria for improved application in gynecologic surgeries. DESIGN: Retrospective cohort study. SETTING: Academic university hospital. PATIENTS: Ninety-seven patients with delayed benign gynecologic procedures owing to the coronavirus disease 2019 pandemic. INTERVENTION(S): Surgical prioritization was assessed using 2 novel scoring systems, the Gynecologic Medically-Necessary Time-Sensitive (Gyn-MeNTS) and modified Elective Surgery Acuity Scale (mESAS) systems for all 93 patients included. MEASUREMENTS AND MAIN RESULTS: The interrater reliability and validity of 2 novel surgical prioritization systems (Gyn-MeNTS and mESAS) were assessed. The Gyn-MeNTS scores were calculated by 3 raters and analyzed as continuous variables, with a lower score indicating more urgency/priority. The mESAS score was calculated by 2 raters and analyzed as a 3-level ordinal variable with a higher score indicating more urgency/priority. All 5 raters were blinded to reduce bias. The Gyn-MeNTS interrater reliability was tested using Spearman r and paired t tests were used to detect systematic differences between raters. Weighted κ indicated mESAS reliability. Concurrent validity with mESAS and surgeon self-prioritization (SSP) was examined with Spearman r and logistic regression. Spearman r's for all Gyn-MeNTS rater pairs were above 0.80 (0.84 for 1 vs 2; 0.82 for 1 vs 3; and 0.82 for 2 vs 3, all p <.001) indicating strong agreement. The weighted κ for the 2 mESAS raters was 0.57 (95% confidence interval, 0.40-0.73) indicating moderate agreement. When used together, both scores were significantly independently associated with SSP, with strong discrimination (area under the curve, 0.89). CONCLUSION: Interrater reliability is acceptable for both scoring systems, and concurrent validity of each is moderate for predicting SSP, but discrimination improves to a high level when they are used together.

Pelvic Neuroanatomy: An Overview of Commonly Encountered Pelvic Nerves in Gynecologic Surgery.

OBJECTIVE: This video tutorial identifies key anatomic landmarks useful in identifying the path of the most commonly encountered pelvic nerves in benign gynecologic surgery. DESIGN: This is a narrated overview of commonly encountered pelvic nerves during benign gynecology, their origin, sensory, and motor function, as well as sequelae related to injury. SETTING: The unintended injury of pelvic neural connections can be a complication of any pelvic surgery, however, surgery for malignancy or endometriosis may increase the likelihood of encountering these nerves. The majority of focus surrounding surgical nerve injury, however, relates to patient positioning [1]. Injury to the pelvic nerves can lead to lifelong sexual, bladder, and defecatory dysfunction [2]. INTERVENTIONS: We review the Genitofemoral, Lateral Femoral Cutaneous, Ilioinguinal, Obturator, Superior and Inferior Hypogastric nerves, Pelvic Splanchnic nerves, and the Sacral nerves. Surgical illustrations are used (Fig. 1) alongside real-time narrated video to help viewers recognize the normal course of commonly encountered pelvic nerves at the time of gynecologic surgery (Figs2-3). CONCLUSION: The surgical management of complex pelvic disease can unfortunately carry significant patient morbidity [3]. The neural pathways traveling through the pelvis via the hypogastric nerves are responsible for proprioception, vaginal lubrication, and proper functioning or the urethral and anal sphincters [4]. Sparing these nerves during pelvic surgery, and especially when anatomic planes are distorted by pelvic disease, requires surgical expertise and an immense understanding of pelvic neuroanatomy [4,5]. Preservation of the pelvic neural pathways is necessary to deliver the best patient outcomes while minimizing unwanted surgical complications. This video tutorial also highlights the origin of these nerves, their anatomic location, procedures in which these nerves may be encountered, and what sequelae occur from their unintended injury.

Augmented Realities, Artificial Intelligence, and Machine Learning: Clinical Implications and How Technology Is Shaping the Future of Medicine.

Technology has been integrated into every facet of human life, and whether it is completely advantageous remains unknown, but one thing is for sure; we are dependent on technology. Medical advances from the integration of artificial intelligence, machine learning, and augmented realities are widespread and have helped countless patients. Much of the advanced technology utilized by medical providers today has been borrowed and extrapolated from other industries. There remains no great collaboration between providers and engineers, which may be why medicine is only in its infancy of innovation with regards to advanced technologic integration. The purpose of this narrative review is to highlight the different technologies currently being utilized in a variety of medical specialties. Furthermore, we hope that by bringing attention to one shortcoming of the medical community, we may inspire future innovators to seek collaboration outside of the purely medical community for the betterment of all patients seeking care.

Robotic surgery during the COVID pandemic: why now and why for the future.

Health care has changed in unprecedented ways since the first reported cases of COVID-19. With global case rates continuing to rise and government restrictions beginning to loosen, many worry that a second wave in our future. In many hospitals around the world, non-emergent surgeries were put on hold as hospitals were transformed into COVID centers. As surgeons and administrators do their best to reinstate non-emergent procedures, guidance is sought from any and all reliable sources. Robotic surgery has many known and demonstrated benefits over open surgery and often over conventional laparoscopy. In this commentary, we aim to highlight some of the advantages robotic surgery may offer during this uniquely challenging time in health care.

Ob/Gyn resident self-perceived preparedness for minimally invasive surgery.

BACKGROUND: Very little is known regarding the readiness of senior U.S. Ob/Gyn residents to perform minimally invasive surgery. This study aims to evaluate the self-perceived readiness of senior Ob/Gyn residents to perform complex minimally invasive gynecologic surgery as well as their perceptions of the minimally invasive gynecologic surgery subspecialty. METHODS: We performed a national survey study of 3rd and 4th year Ob/Gyn residents. A novel 58-item survey was developed and sent to residency program directors and coordinators with the request to forward the survey link along to their senior residents. RESULTS: We received 158 survey responses with 84 (53.2%) responses coming from 4th year residents and 74 (46.8%) responses from 3rd year residents. Residents who train with graduates of a fellowship in minimally invasive gynecologic surgery felt significantly more prepared to perform minimally invasive surgery compared to residents without this exposure in their training. The majority of senior residents (71.5%) feel their residency training adequately prepared them to be a competent minimally invasive gynecologic surgeon. However, only 50% feel prepared to perform a laparoscopic hysterectomy on a uterus greater than 12 weeks size, 29% feel prepared to offer a vaginal hysterectomy on a uterus 12-week size or greater, 17% feel comfortable performing a laparoscopic myomectomy, and 12% feel prepared to offer a laparoscopic hysterectomy for a uterus above the umbilicus. CONCLUSIONS: The majority of senior U.S. Ob/Gyn residents feel prepared to provide minimally invasive surgery for complex gynecologic cases. However, surgical confidence in specific procedures decreases when surgical complexity increases.

Current Management of Gynecologic Trauma.

INTRODUCTION: To date, there are few reports describing the management of traumatic gynecologic injuries leaving physicians with little guidance. OBJECTIVE: Describe the injury patterns and the preferred management of these injuries. METHODS: A retrospective cohort study was performed using the National Trauma Data Bank (NTDB) from years 2011 to 2013. Female patients age 16 years and older with internal gynecologic injuries were identified based on diagnosis codes. Demographics, associated diagnoses and procedure codes were compiled for the cohort. RESULTS: 313 patients met inclusion criteria. The mechanism of injury was blunt in 236 (75%) patients, penetrating in 68 (21%), and other in 9 (4%). The mean Injury Severity Score was 16.6 ± 14.6. Mean age was 34 ± 21 years old. 226 (74.8%) patients had an ovarian and/or fallopian tube injury, 71 (25.2%) had a uterine injury, 8 (3%) had both, and 8 (3%) had injury to the ovarian or uterine vessels only. Of the 226 patients with ovarian and/or fallopian tube injury, 11(5%) underwent repair and 10 (4%) underwent salpingo-oophorectomy. Of the 71 uterine injuries, 15 (21%) underwent repair and 5 (7%) required a hysterectomy. CONCLUSIONS: Most traumatic internal gynecologic injuries result from blunt mechanism. Currently, these injuries are largely managed non-operatively. When surgery was performed, ovarian and uterine repair was more common than salpingo-oophorectomy and hysterectomy. Prospective large-scale studies are needed to establish a standard of treatment for the management of gynecologic trauma and to assess both short and long term outcomes and fertility rates.

Cost variance across obesity class for women undergoing laparoscopic hysterectomy by high-volume gynecologic surgeons.

Health-care costs are affected by obesity with both the direct and indirect costs of health care increasing as body mass index (BMI) increases. However, one important aspect of obesity that lacks rigorous study is what impact BMI has on direct surgical cost. We performed a retrospective cohort study of women undergoing a laparoscopic hysterectomy at our single academic university center between January 2012 and December 2017. Women were excluded if their surgery was performed by anyone other than those surgeons with subspecialty training in minimally invasive gynecologic surgery (MIGS), if their hysterectomy was performed by a modality other than conventional laparoscopy or with robotic assistance, or if the indication for hysterectomy was related to any gynecologic malignancy. We identified 600 patients who underwent laparoscopic hysterectomy during the study period. Women who underwent robotic hysterectomy, compared to laparoscopic, had a shorter operative time, lower estimated blood loss, and shorter length of stay. Mean direct cost (± standard deviation) for the cohort was $6398.53 ± $2304.67, age was 44.5 ± 7.5 years, and BMI was 32.2 ± 7.6. Direct cost for all laparoscopic hysterectomies was evaluated across the five different BMI quintiles and no significant difference between groups was found. There was no significant difference in direct cost across procedures between obese and non-obese patients (p = 0.62) and this remained true when separated out by surgical modality. However, when evaluating morbidly obese patients, there appears to be a trend toward cost reduction with robotic hysterectomy compared to conventional laparoscopy. It does not appear that BMI has a statistically significant impact on direct cost between robotic-assisted and conventional laparoscopic hysterectomy. However, these findings may be due to surgical proficiency and warrant further investigation among surgeons with lesser volume.
