Robot-Assisted Surgery for Endometriosis Current and Future Perspectives.

Successful resection of all visible lesions may effectively treat endometriosis-related infertility and pelvic pain. Minimally invasive surgery provides significant advantages, with lower rates of surgical complications such as surgical trauma, infection, postoperative pain, and hospital stay. Robotic surgery is shown to have similar perioperative outcomes to conventional laparoscopy; however, complex stage III and IV endometriosis, especially cases requiring significant resection such as deep infiltrating endometriosis, widespread peritoneal implants, and urologic and intestinal involvement, may benefit most from a robotic approach. There are certain aspects of endometriosis surgery where utilization of robotic technology might provide an additional benefit. These include (1) heterogeneity of lesions, and thus difficulty in identification; (2) difficulty in accurately predicting surgical complexity; and (3) prolonged operative time for complex cases. The objective of this review is to describe the current and future perspectives of robotic surgery as it pertains to endometriosis.

Impact of lifestyle and diet on endometriosis: a fresh look to a busy corner.

Endometriosis is a chronic inflammatory disorder with a prevalence of six to ten percent in women of childbearing age. As long as the aetiology of endometriosis is not fully understood and the disease has no definitive treatment, an examination of the environmental factors or interventions that could modify or cure endometriosis would greatly benefit women suffering from this chronic condition. This literature review utilized the electronic databases PubMed, EMBASE, and MEDLINE until February 2021. Studies indicate that fish oil may have a positive effect on reducing endometriosis-related pain due to the effects of pro-inflammatory prostaglandins derived from omega-3 fatty acids. The same effect was seen with the introduction of antioxidant vitamins C, D, and E. There is clinical viability of a low fermentable oligo-, di-, and mono-saccharides and polyols diet to successfully reduce the symptoms of patients who suffer from both endometriosis and irritable bowel syndrome. Despite the low level of evidence, there are frequent associations between endometriosis and gastrointestinal conditions in addition to the influence of various nutritional factors on the disease. The management of endometriosis requires a holistic approach focused on reducing overall inflammation, increasing detoxification, and attenuating troublesome symptoms. A dietician may provide great benefit in the management of these patients, especially at younger ages and in early stages. High-level evidence and well-designed randomized studies are lacking when it comes to studying the effect of lifestyle and dietary intake on endometriosis. Inarguably, further research with a more extensive focus is needed.

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.

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.

The effect of anemia severity on postoperative morbidity among patients undergoing laparoscopic hysterectomy for benign indications.

INTRODUCTION: One-third of non-pregnant women worldwide are anemic.1 Anemia is a known independent risk factor for postoperative morbidity.2 Given that the vast majority of hysterectomies are not performed in the emergency setting, we designed this study to evaluate the effect of preoperative anemia on postoperative morbidity following laparoscopic hysterectomy performed for benign indications. Our main goal is to encourage surgeons to use anemia-corrective measures before surgery when feasible. MATERIAL AND METHODS: Retrospective cohort study of 98 813 patients who underwent a laparoscopic hysterectomy between 2005 and 2016 for benign indications identified through the American College of Surgeons National Surgical Quality Improvement Program. Anemia was examined as a function of hematocrit and was analyzed as an ordinal variable stratified by anemia severity as mild, moderate or severe. Associations between preoperative anemia and patient demographics, preoperative comorbidities and postoperative outcomes were evaluated using univariate analyses. Multivariable logistic regression models were used to identify independent associations between hematocrit level and postoperative outcomes after adjusting for confounding covariates. At the multivariable logistic regression level, anemia severity was analyzed using hematocrit as a continuous variable to assess the independent association between each 5% decrease in hematocrit level and several postoperative morbidities. RESULTS: Of the 98 813 patients who met our inclusion and exclusion criteria, 19.5% were anemic. A lower preoperative hematocrit was associated with higher body mass index, younger age, Black or African American race, longer operative times, and multiple other medical comorbidities. After appropriate regression modeling, anemia was identified as an independent risk factor for extended length of stay, readmission and composite morbidity after surgery. CONCLUSIONS: Preoperative anemia is common among patients undergoing laparoscopic hysterectomy. Preoperative anemia increases patients' risk for multiple postoperative comorbidities. Given that most hysterectomies are performed in the elective setting, gynecologic surgeons should consider the use of anemia-corrective measures to minimize postoperative morbidity.

Effect of Perioperative Transfusion on Postoperative Morbidity Following Minimally Invasive Hysterectomy for Benign Indications.

STUDY OBJECTIVE: To examine the impact of perioperative allogeneic blood transfusion (ABT) on postoperative infectious wound occurrences, sepsis-related events. and venous thromboembolism. DESIGN: Retrospective cohort study. SETTING: Hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). PATIENTS: Patients who underwent a minimally invasive hysterectomy for benign indications between 2012 and 2016 were selected from the ACS-NSQIP. Patients with concurrent open hysterectomy, prolapse, or malignancy were excluded. Those with preoperative, intraoperative or postoperative red blood cell transfusion were considered positive for perioperative ABT. INTERVENTION: Minimally invasive hysterectomy for benign indications. MEASUREMENTS AND MAIN RESULTS: Univariate analyses were performed to determine associations of preoperative and intraoperative patient variables and postoperative outcomes with perioperative ABT. Multivariate analysis was completed to test the independent associations of perioperative ABT with outcomes while adjusting for possible confounders. Of the 90,231 patients who met our inclusion criteria, 1447 had a perioperative transfusion (1.6%). Perioperative ABT was associated with multiple preoperative variables. After multivariate analysis, perioperative ABT remained significantly associated with infectious wound events (adjusted odds ratio [aOR], 1.96; 95% confidence interval [CI], 1.9-2.58; p < .001), thromboembolic events (aOR, 2.75; 95% CI, 1.5-5.05; p = .001), and sepsis events (aOR, 6.49; 95% CI, 4.29-9.79, p < .001). CONCLUSION: ABT is a commonly used to treat perioperative anemia in patients undergoing gynecologic surgery. The results of this study, however, show that perioperative ABT increases a patient's risk of postoperative complications following minimally invasive hysterectomy. Gynecologic surgeons should consider the use of alternative treatments for perioperative anemia, including intravenous iron supplementation, erythropoiesis-stimulating agents, normovolemic hemodilution, and preoperative hormonal suppression, to help reduce the morbidity associated with perioperative ABT.

Perioperative Narcotic Trends in Women Undergoing Minimally Invasive Myomectomy.

STUDY OBJECTIVE: Evaluate the perioperative narcotic utilization patterns at the time of myomectomy, specifically as they relate to the opioid epidemic. We also aim to evaluate the differences between conventional laparoscopy and robotic surgery in terms of narcotic utilization. DESIGN: Retrospective cohort study. SETTING: Single academic university hospital. PATIENTS: Women undergoing minimally invasive myomectomy. INTERVENTIONS: Laparoscopic or robot-assisted myomectomy. MEASUREMENTS AND MAIN RESULTS: We identified 312 minimally invasive myomectomies to be included in the final analysis. For the entire cohort, the mean age (± standard deviation) was 35.7 ± 5.1 years, and the mean body mass index was 28.3 ± 6.3. Of the 312 myomectomies included, 239 (76.6%) were performed using robotic assistance, and the remainder (23.4%) were performed by conventional laparoscopy. A statistically significant inverse relationship was found between year of myomectomy and perioperative narcotic administration (p <.001). Yearly morphine milligram equivalent (MME) administration decreased significantly for both intraoperative and postoperative administration (p <.001). The largest decline for intraoperative MME use was between 2016 and 2017, and for postoperative MME use, it was between 2012 and 2013. There was no statistically significant difference in perioperative narcotic administration between conventional laparoscopy and robot-assisted myomectomy. The time effect for intraoperative (p <.001) and postoperative (p <.001) narcotic administration remained significant after adjusting for covariates, including mode of surgery, race, insurance, age, and body mass index. None of the background variables assessed were associated with perioperative narcotic administration. CONCLUSION: Perioperative narcotic administration for minimally invasive myomectomy has decreased following widespread awareness of the national opioid crisis.

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.

Surgical management of neuroproliferative-associated vestibulodynia: a tutorial on vestibulectomy with vaginal advancement flap.

Provoked vestibulodynia is an often underdiagnosed and mismanaged medical condition that impacts the lives of many women. When symptoms are due to a dramatically increased density of pain fibers in the vestibular endoderm, the condition is referred to as neuroproliferative-associated vestibulodynia. Unfortunately, assessment of pain fiber density can only be performed after surgery during histologic examination. First-line therapies for this condition often include topical or oral medications targeting hyperalgesia and allodynia at the vulvar vestibule. However, in the setting of refractory disease, surgical treatment should be considered. The surgical video (Video 1) highlights anatomical landmarks as well as key surgical steps when performing a vulvar vestibulectomy with a vaginal advancement flap for the treatment of neuroproliferative-associated vestibulodynia. Surgeons should have a thorough understanding of pertinent vulvar anatomical landmarks before performing this procedure (Figure 1). The goal of vulvar vestibulectomy, as described in this video, is to excise the entirety of the vestibule containing the pathologic density of afferent pain fibers. This tutorial serves to identify key anatomical landmarks including Hart's line as well as outline the meticulous dissection required for successful completion of this procedure. We describe our surgical instrumentation as well as provide insight into steps that can be taken to minimize postoperative morbidity.

Applications of Tranexamic acid in benign gynecology.

PURPOSE OF REVIEW: Bleeding at the time of benign gynecologic surgery, as well as from benign gynecologic conditions, is a major source of morbidity for many women. Few nonhormonal medical options exist for the treatment of heavy menstrual bleeding, and to reduce surgical bleeding during major gynecologic surgery. Interest in Tranexamic acid (TXA) as a means to reduce surgical blood loss has been growing across many surgical specialties. This review focuses on applications for TXA as a means to reduce heavy menstrual bleeding (HMB) as well as to reduce surgical bleeding during benign gynecologic surgery. RECENT FINDINGS: Tranexamic acid is an effective treatment to reduce the volume of bleeding during menstruation. Tranexamic acid was found to be superior to both placebo and oral progestins, and as good as combined oral contraceptives at reducing menstrual blood volume. Tranexamic acid has also been show to reduce the volume of bleeding during abdominal myomectomy as well as hysterectomy. There is a major need for prospective studies evaluating the utility of TXA for reducing blood loss during benign gynecologic surgery. SUMMARY: Tranexamic acid has been found to be an excellent affordable nonhormonal treatment option for women with HMB and should be considered during major gynecologic surgery.

Technique for Tissue Containment and Extraction in the Complex Minimally Invasive Myomectomy Setting.

STUDY OBJECTIVE: To achieve tissue containment and extraction for numerous and large myomas in the complex minimally invasive difficult myomectomy setting via a surgical tutorial including technical pointers and suggestions DESIGN: A step-by-step explanation of the .surgery using video (instructive video) (Canadian Task Force classification III). Institutional review board approval was not required for this study. SETTING: George Washington University Hospital, Washington, DC. PATIENTS: Multiple patients with a high number or large size of leiomyomata. INTERVENTIONS: Four reproducible techniques that enable the minimally invasive gynecologic surgeon to perform complex tissue containment and extraction: MEASUREMENTS AND MAIN RESULTS: One of the main challenges encountered with minimally invasive myomectomy procedures includes myoma containment and extraction. Given the potential risks for leiomyomatosis and the spread of leiomyosarcoma, the Food and Drug Administration banned electromechanical morcellation device usage [1]. After implementation of the ban and fueled by the increasing size and number of myomas removed through minimally invasive techniques, tissue containment and extraction are becoming increasingly challenging. This shift is partly reflected by the number of complications attributable to surgeon experience [2,3]. With the increase in the number of myomas removed during a minimally invasive myomectomy, the risk of myoma retention in the abdominal cavity is amplified. Also, the increase in the myoma size removed through minimally invasive surgery renders tissue extraction through contained, extracorporeal, manual morcellation more challenging [2-5]. Inefficiencies in tissue containment and extraction could potentially be hazardous to the patient's safety and detrimental to the operating room efficiency, and the AAGL Practice Report on tissue extraction emphasizes that the use of specimen retrieval pouches should be investigated further [2-6]. Patients underwent uncomplicated complex minimally invasive myomectomy. CONCLUSION: Mastering these reproducible techniques maximizes patient safety and operating room efficiency during minimally invasive myomectomy procedures.

Impact of Diabetes Mellitus on Postoperative Complications Following Laparoscopic Hysterectomy for Benign Indications.

BACKGROUND: Current research pertaining to minimally invasive gynecologic surgical outcomes in the context of diabetes mellitus (DM) is limited. This study seeks to evaluate the association between DM and postoperative complications following laparoscopic hysterectomy for benign indications. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was utilized. We identified laparoscopic hysterectomies completed for benign indications from 2007 to 2016 using current procedural terminology codes. Complications were evaluated by DM status: non-insulin-dependent DM (NIDDM), insulin-dependent DM (IDDM), and non-DM. Postoperative complications were evaluated utilizing univariate and multivariate analyses. RESULTS: We identified 56,640 laparoscopic hysterectomies. Though both the IDDM and NIDDM cohorts had an increased incidence of postoperative complications compared to the non-diabetes cohort. The IDDM group had the highest incidence of all 3 cohorts. Compared to non-DM, the IDDM group had higher odds of reintubation (OR 4.23; 95% CI 1.59-11.19), urinary tract infection (OR 1.45; 95% CI 1.022-2.069), and extended length of stay (OR 1.75; 95% CI 1.36-2.26). CONCLUSION: Both NIDDM and IDDM were independent risk factors for postoperative complications after laparoscopic hysterectomy. However, the IDDM cohort had the highest odds of complications. Diabetic patients should be carefully counseled regarding their elevated risk of perioperative complications.

Novel Approach for 2-Port Laparoscopic Hysterectomy.

Background and Objectives. To describe a novel technique for a port-reducing laparoscopic hysterectomy. The 2-port laparoscopic hysterectomy (TPH) is performed through two 5-mm ports without the use of any multiport channels. We demonstrate outcomes via a large case series. We also describe and provide a video showing the TPH technique. Methods. Retrospective comparative study between the newly developed TPH and the conventional 4-port hysterectomy techniques. Variables of patients who underwent a TPH with fellowship-trained gynecologic surgeons at a single academic university hospital were collected through electronic medical records chart review. Results. Forty-five patients underwent a TPH. Mean age was 39.4, body mass index was 28.5 kg/m2, and uterine weight was 170.0 g. Our outcomes of interest were operative time (98.4 minutes, mean), estimated blood loss (65.6 mL, mean), conversion to 3-port (1/45), and intraoperative (0/45) and postoperative (5/45) complications. By comparing the TPH to the conventional 4-port laparoscopic hysterectomy within a similar setting, we provide insight into variables that prompt the minimally invasive gynecologic surgeon to perform a port-reducing procedure. Patients were more likely to be allocated for a TPH if they were younger (37.8 vs 44.7, P = .005), had a lower body mass index (29.0 vs 32.5, P = .07), smaller uterus (143.1 vs 672.3 g, P < .001), and were white (56.8% and 22.4%, P < .001). Conclusions. The TPH is a novel port-reducing hysterectomy that is safe in a subset of patients with small uteri and limited surgical history who require no other surgical interventions at the time of hysterectomy.

Surgical variance between postconceptional and preconceptional minimally invasive transabdominal cerclage placement.

Recent data show that transabdominal cerclage placement via laparoscopy carries better obstetrical outcomes in comparison to transabdominal cerclage placement via laparotomy. In this surgical tutorial, we review the technique for minimally invasive abdominal cerclage and highlight the surgical differences between preconceptional and conceptional cerclage.

Multidisciplinary Resection of Deeply Infiltrative Endometriosis.

STUDY OBJECTIVE: To describe a multidisciplinary approach for the resection of deeply infiltrative endometriosis using the robotic platform. DESIGN: A technical video showing a step-by-step approach for the resection of deeply infiltrative endometriosis (Canadian Task Force classification level III). Institutional review board approval was not required for this study. SETTING: There is considerable involvement of the bowel and bladder with deeply infiltrative endometriosis [1-3]. The need for operative procedures involving multiple organs while performing a complete resection is common. The benefits of minimally invasive surgery for a gynecologic pathology have been documented in numerous studies. Patients had fewer medical and surgical complications postoperatively, better cosmesis, and better quality of life [4-6]. We believe that deeply infiltrative endometriosis does not preclude patients from having a minimally invasive resection procedure. In this video, we describe how the robotic platform was used for a seamless transition between surgical specialties including gynecology, colorectal, and urology to ensure complete resection of endometriosis lesions involving multiple organs. PATIENT: A 47-year-old woman with a 4-year history of severe pelvic pain, dysuria, dyspareunia, dyschezia, and dysmenorrhea failing multiple medical therapies presented to our clinic to discuss surgical options. After thorough counseling, the decision was made to proceed with definitive surgical management. Postoperatively, the patient was admitted for 2 days of postoperative inpatient care. After meeting all immediate postoperative milestones, she was discharged with an indwelling Foley catheter and instructed to follow up in the clinic with all 3 surgical specialties. At the 1-week interval, she was seen by the urology team; her indwelling catheter was removed after a cystoscopy was performed documenting adequate healing. Two weeks postoperatively, the patient was seen by the gynecology and colorectal teams and was noted to be healing adequately from the procedure. Her six-week visit was also unremarkable. She continued to follow up with the gynecology team for her yearly well-woman examinations and has been symptom free for 2 years after the surgery. She takes norethindrone daily to minimize recurrence. INTERVENTIONS: Preoperative pelvic magnetic resonance imaging (MRI) showed bladder endometriosis and extensive rectovaginal endometriosis. We describe the multidisciplinary approach used for surgery and the procedures performed by each specialty. The urology team performed a cystoscopy preoperatively to assess for full-thickness erosions and the location of those lesions in that event. The urology team also reviewed the magnetic resonance images with the radiology team, and the endometriosis lesions were suspected to be close to the bladder trigone, keeping in mind that this finding could be overestimated given that the bladder was deflated at the time the imaging was obtained. Accordingly, at the time of surgery, the decision was made to proceed with cystoscopy and the placement of ureteral stents as a prophylactic measure. An intentional cystotomy and resection of the bladder section involved with endometriosis were performed followed by watertight closure. The trigone area of the bladder was not involved, and ureteral reimplantation was not needed in this case. The gynecology team operated second and performed an extensive dissection of the retroperitoneal space with the development of the pararectal and paravesical spaces. They also ligated the uterine artery at its origin followed by dissection of the uterovesical space, effectively reflecting the bladder off of the lower uterine segment. At this point, they proceeded with a total hysterectomy, and the specimen was removed from the pelvis through the vaginal cuff. Preoperatively, the colorectal surgeon ordered a colonoscopy to determine if full-thickness erosions were present and reviewed the magnetic resonance images with the radiology team. Based on the MRI and colonoscopy, all patients are counseled and consented for the possibility of a low anterior resection and loop ileostomy to protect the anastomosis. Based on the understanding that colorectal and gynecologic surgeries have a different approach when dissecting the pararectal space at our institution, a discussion between the 2 teams is initiated at the multidisciplinary session for surgery planning. In the case we present, the colorectal surgeon opted for the removal of the uterus before his dissection was initiated given that he dissects this space presacrally and not retroperitoneally like the gynecology counterpart. He would also benefit from the extra space for dissection with the uterus out of the pelvis. The colorectal part of the case was initiated by mobilization of the rectum and dissecting the obliterated rectovaginal space. The presacral space was then opened followed by mobilization of the rectosigmoid from its attachment. The case was concluded with full transection and reanastomosis of the rectum section involved with endometriosis. The specimen was also removed from the pelvis through the vaginal cuff. MEASUREMENTS AND MAIN RESULTS: Complete resection of deeply infiltrative endometriosis spanning beyond the scope of 1 surgical specialty. No immediate intraoperative, perioperative, or long-term complications from surgery. Complete resolution of endometriosis symptoms. CONCLUSION: We encourage collaborative care for planning and performing comprehensive and safe resection of deeply infiltrative endometriosis.

Systematic Review of Transabdominal Cerclage Placed via Laparoscopy for the Prevention of Preterm Birth.

Preterm birth is the leading cause of neonatal mortality and morbidity. Multiple interventions are available to minimize this occurrence; however, despite current recommendations including medical management, cervical length screening, and transvaginal cerclage, a substantial number of women still experience preterm birth. For those patients, experts recommend transabdominal cerclage (TAC). In this systematic review, we compared 26 studies (1116 patients) of TAC placed via laparotomy (TAC-lap) and 15 studies (728 patients) of TAC placed via laparoscopy (TAC-lsc). There was no significant difference in overall neonatal survival between the TAC-lsc and TAC-lap groups (89.9% vs 90.8%, respectively; p = .80). When T1 losses were excluded, the neonatal survival rate was significantly higher for the TAC-lsc group (96.5% vs 90.1%; p < .01). In terms of obstetrical outcomes, the TAC-lsc group had a higher rate of deliveries at gestational age (GA) > 34 weeks (82.9% vs 76%; p < .01) and a lower rate of deliveries at GA 23.0 to 33.6 weeks (6.8% vs 14.8%; p < .01). The TAC-lsc group also had fewer T2 losses (3.2% vs 7.8%; p < .01). TAC-lsc offers all the benefits of minimally invasive surgery with better obstetrical outcomes compared with TAC-lap.

Feasibility, Safety, and Prediction of Complications for Minimally Invasive Myomectomy in Women With Large and Numerous Myomata.

OBJECTIVE: To assess perioperative outcomes and identify predictors of complications for minimally invasive surgery (MIS) myomectomy in a cohort of women with large and numerous myomata. DESIGN: Case-control study (Canadian Task Force classification II-2). SETTING: Academic tertiary care medical center. PATIENTS: Women undergoing MIS myomectomy performed by 3 high-volume surgeons between April 2011 and December 2014. INTERVENTIONS: Characteristics were compared between women who experienced complications and those who did not. Factors predictive of complications were then identified. MEASUREMENTS AND MAIN RESULTS: A total of 221 women underwent an MIS myomectomy, 47.5% via a laparoscopic approach and 52.5% via robotic surgery. The mean ± SD specimen weight was 408.1 ± 384.9 g, uterine volume was 586.1 ± 534.1 cm3, dominant myoma diameter was 9.6 ± 5.1 cm, and number of myomata removed was 4.5 ± 4.1. The most common complications were hemorrhage >1000 mL (8.6%) and blood transfusion (4.1%). The conversion rate was 1.8%. A dominant myoma diameter of ≥12 cm and a uterine volume of ≥750 cm3 increased the odds of complications (odds ratio [OR], 7.44; 95% confidence interval [CI], 2.03-31.84; p = .004 and OR, 6.15; 95% CI, 1.55-30.02; p = .014 respectively). A receiver operating characteristic curve considering dominant myoma diameter and uterine volume had an area under the curve of 0.81. A combination of dominant myoma diameter of ≥10 cm and uterine volume of 600 cm3 predicted complications with 79% sensitivity and 79% specificity. CONCLUSION: Our cohort had large and numerous myomata with high specimen weights, but complications were comparable to those reported in previous studies of MIS myomectomy with less complex pathology. Hemorrhage and transfusion accounted for the majority of complications, and a combination of dominant myoma diameter and uterine volume was predictive of complications. Both factors can be easily defined before surgery and may be used to guide patient counseling, referrals, and implementation of preventative measures for hemorrhage and transfusion.

Comparison of methods of morcellation: manual versus power.

INTRODUCTION: With the growing controversy surrounding power morcellation (PM), other approaches must be examined so that women may still benefit from minimally invasive gynecologic surgeries. In this study we sought to compare power morcellation to manual morcellation through mini-laparotomy or vaginally. MATERIALS AND METHODS: Retrospective cohort study carried out at an urban teaching hospital including 274 women who underwent a minimally invasive myomectomy or hysterectomy, requiring morcellation for tissue extraction. Surgical outcomes were compared between PM, manual morcellation through mini-laparotomy (MMM) and manual morcellation through the vagina (MMV). Primary outcome measured was operative time. Secondary outcomes were intraoperative and postoperative complications. RESULTS: Compared with PM, MMM was associated with shorter operative time for hysterectomy, (140.5 min vs. 164.2 min, p = 0.05). Intraoperative and postoperative complications were similar among groups. There were four postoperative complications in the MMV group, one related to blood transfusion and three related to postoperative vaginal cuff and pelvic infections. CONCLUSION: Compared with PM, MMM is associated with shorter operative time during hysterectomies. Intraoperative and postoperative complications were similar among groups.

Abdominal Approaches to Tissue Containment and Extraction in Minimally Invasive Gynecologic Surgery.

STUDY OBJECTIVE: To show different abdominal methods of tissue containment and specimen extraction techniques as an alternative to electromechanical morcellation (EMM). DESIGN: A stepwise surgical tutorial using a narrated video (Canadian Task Force classification III). SETTING: An academic tertiary care hospital. INTERVENTIONS: Minimally invasive gynecologic surgery requires the extraction of large tissue specimens through small incisions. EMM was largely used until recently when the Food and Drug Administration issued a statement on its safety. In this video, we present alternative techniques to EMM as well as different methods of tissue containment. Uteri specimens are contained using a 3M Steri-Drape isolation bag (3M Healthcare, Maplewood, MN) and, alternatively, the Alexis Containment Extraction System (Applied Medical, Rancho Santa Margarita, CA). The contained specimen is manually extracted through the 2.5-cm umbilical port incision using the paper roll technique described here. CONCLUSION: These techniques for tissue containment and extraction provide an alternative to EMM. They allow the minimally invasive surgeon to contain and retrieve large specimens. When used appropriately, these techniques can decrease conversion rates to open abdominal surgery. They are easily reproducible with a minimal learning curve.
