Perioperative Venous Thromboembolism Risk in Patients Undergoing Hysterectomy for Fibroids: A US Retrospective Cohort Study

OBJECTIVES

Venous thromboembolism (VTE) occurs in 0.4%-0.7% of benign hysterectomies. Pelvic vascular compression secondary to fibroids may elevate VTE risk. We aimed to evaluate the incidence and timing of VTE among individuals undergoing hysterectomy for fibroids and other benign indications.

METHODS

Retrospective cohort study of patients who underwent a hysterectomy for fibroid and non-fibroid indications from January 2015 to December 2021. Main outcome measure was VTE consisting of pulmonary embolism or deep venous thrombosis diagnosed during 3 periods: (1) preoperative (1 year before surgery until day before surgery), (2) early postoperative (surgery date through 6 weeks after surgery), and (3) late postoperative (6 weeks to 1 year after surgery). Demographics, comorbidities, surgical characteristics, and VTE rates were compared by indication.

RESULTS

A total of 263 844 individuals with fibroids and 203 183 without were identified. In total, 1.1% experienced VTE. On multivariable regression (adjusted demographic confounders and route of surgery), the presence of fibroids was associated with increased odds of preoperative (adjusted odds ratio [aOR] 1.12; 95% CI 1.03-1.22, P = 0.011) and reduced odds of late postoperative VTE (aOR 0.81; 95% CI 0.73-0.91, P < 0.001). For individuals with fibroids, uterine weight ≥250 g and undergoing laparotomy were independently associated with preoperative (aOR 1.29; 95% CI 1.09-1.52, P = 0.003 and aOR 2.32; 95% CI 2.10-2.56, P < 0.001) and early postoperative VTE (aOR 1.32; 95% CI 1.08-1.62, P = 0.006 and aOR 1.72; 95% CI 1.50-1.96, P < 0.001).

CONCLUSIONS

Patients with fibroids were at increased odds of having VTE 1 year before hysterectomy. For those with fibroids, elevated uterine weight and laparotomy were associated with greater risk of preoperative and early postoperative VTEs.

Society of Radiologists in Ultrasound Consensus on Routine Pelvic US for Endometriosis

Endometriosis is a prevalent and potentially debilitating condition that mostly affects individuals of reproductive age, and often has a substantial diagnostic delay. US is usually the first-line imaging modality used when patients report chronic pelvic pain or have issues of infertility, both common symptoms of endometriosis. Other than the visualization of an endometrioma, sonologists frequently do not appreciate endometriosis on routine transvaginal US images. Given a substantial body of literature describing techniques to depict endometriosis at US, the Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts to make recommendations aimed at improving the screening process for endometriosis. The panel was composed of experts in the imaging and management of endometriosis, including radiologists, sonographers, gynecologists, reproductive endocrinologists, and minimally invasive gynecologic surgeons. A comprehensive literature review combined with a modified Delphi technique achieved a consensus. This statement defines the targeted screening population, describes techniques for augmenting pelvic US, establishes direct and indirect observations for endometriosis at US, creates an observational grading and reporting system, and makes recommendations for additional imaging and patient management. The panel recommends transvaginal US of the posterior compartment, observation of the relative positioning of the uterus and ovaries, and the uterine sliding sign maneuver to improve the detection of endometriosis. These additional techniques can be performed in 5 minutes or less and could ultimately decrease the delay of an endometriosis diagnosis in at-risk patients.

Patient-Reported Outcome Measures Used in Randomized Controlled Trials Following Surgical Intervention for Endometriosis: A Structured Review from the AAGL Practice Guidelines Group

OBJECTIVE

No consensus currently exists regarding patient-reported outcome measure (PROM) instruments. This structured review was conducted to identify the PROMs used by randomized controlled trials (RCTs) that evaluated surgical treatment in patients with endometriosis.

DATA SOURCES

Two parallel searches were conducted by a medical librarian using Ovid MEDLINE, Ovid Embase, and Cochrane Library for RCTs published from 2000 to July 2022. One search focused on studies reporting quality of life (QoL), and the second search focused on studies reporting pain and sexual, bowel, and bladder function.

METHOD OF STUDY SELECTION

During the title and abstract screening and reference check, 600 results were identified on PROMs relating to QoL and 465 studies on PROMs relating to pain and sexual, bowel, and/or bladder function and an evaluation of 17 and 12 studies conducted, respectively. The inclusion criteria involved selecting RCTs that focused on surgical intervention and assessing QoL, pain, and sexual, bowel, and/or bladder function using PROMs.

TABULATION, INTEGRATION, AND RESULTS

Covidence software was used to organize and identify duplicate articles through screening. We developed a data extraction form to collect key information about each included study, as well as the pertinent PROMs used in the study. Assessment of the risk of bias of each study was also performed. A total of 19 studies were identified involving 2089 participants and a total of 16 PROMs used across the studies; 9 of 19 studies (47%) were rated as having a low risk of bias. There were no high-risk studies identified in this review.

CONCLUSION

This study identified a large number of RCTs in surgical treatment of endometriosis that used various PROMs to assess QoL, pain, and bladder, bowel, and sexual function. The PROMs used by high-quality RCTs for QoL include Endometriosis Health Profile-30, Endometriosis Health Profile-5, Short-Form 36, Short-Form 12, and EQ-5D; for bowel-related symptoms Knowles-Eccersley-Scott-Symptom Questionnaire, Gastrointestinal Quality of Life Index, and Cleveland Clinic Fecal Incontinence Severity Scoring System/Wexner; for bladder-related function Bristol Female Lower Urinary Tract Symptoms, International Prostate Symptom Score, Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire, and Urinary Symptom Profile; and finally for sexual function Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire and Sexual Activity Questionnaire. Unlike other domains, only one tool (visual analog scale) was the dominant PROM used for the assessment of pain. In addition, the use of more than one PROM in each study to assess different aspects of patient's health and pain symptoms did not become prevalent until after 2015.

Diagnostic considerations and surgical techniques for a large prolapsing submucosal myoma

OBJECTIVE

To review important diagnostic considerations for accurate identification of a prolapsing submucosal myoma and to highlight surgical techniques for minimally invasive and uterine-sparing combined vaginal and hysteroscopic myomectomy. Submucosal myomas can present with various symptoms, including vaginal bleeding, pelvic pain, and abnormal discharge, and can also contribute to infertility. This type of myoma has the potential to prolapse through the cervical canal, and prompt identification and management are essential to avoid serious sequelae, including hemorrhage, infection, and sepsis.

DESIGN

A case report. Patient consent was received to publish. This publication received an exemption from institutional review board approval from the institution as this was a case report. The investigators have no conflicts of interest.

SETTING

Academic medical center.

PATIENTS

We present a 33-year-old G5P2032 patient with pelvic pain and vaginal bleeding. Her clinical course involved multiple encounters with inaccurate diagnoses, leading to worsening symptoms. She was found ultimately to have a large, prolapsing submucosal myoma. The patient included in this video gave consent for publication of the video and posting of the video online, including on social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, and others), and other applicable sites.

INTERVENTION(S)

Given the severity of her symptoms and her desire for uterine preservation for future fertility, the patient was counseled on the need for surgical intervention and elected to proceed with a combined vaginal and hysteroscopic myomectomy.

MAIN OUTCOME MEASURE(S)

Preoperative considerations discussed in this video include common mimics of this condition, the importance of a thorough pelvic examination and preoperative imaging, as well as recommendations for surgical management.

RESULT(S)

We reviewed the following surgical techniques: (1) adequate exposure; (2) clamping of the myoma stalk; (3) morcellation "cone" technique; (4) use of intracervical vasopressin; (5) hysteroscopic evaluation; and (6) insertion of an intrauterine balloon.

CONCLUSION(S)

Prolapsing submucosal myomas can present as common gynecologic complaints but can lead to serious sequelae when timely diagnosis and treatment are not performed. Appropriate evaluation, accurate diagnosis, preoperative imaging, and knowledge of surgical techniques are critical for optimizing patient outcomes and avoiding complications in patients with a prolapsed myoma.

Multidisciplinary approach to the surgical management of interstitial ectopic pregnancy

OBJECTIVE

To present a multidisciplinary approach to localize and resect suspected interstitial ectopic pregnancies. Interstitial ectopic pregnancies are distinct from eccentric intracavitary pregnancies and are defined by ultrasound-based criteria, including an empty uterine cavity, gestational sac located >1 cm from the cavity, thin overlying myometrium <5 mm, and the interstitial line sign.

DESIGN

Case report.

SETTING

Academic medical center.

PATIENT(S)

Here, we present the case of a 28-year-old patient at 6 weeks of gestation by last menstrual period who presented to the emergency department with spotting. Initial pelvic ultrasound findings demonstrated a gestational sac and yolk sac that were believed to be located eccentrically within the uterine cavity. Follow-up imaging was performed 2 weeks later that revealed the pregnancy was located at the uterotubal junction and distinct from the endometrial cavity, consistent with an interstitial ectopic. The patient had ongoing light spotting with mild cramping, a benign clinical exam, and normal laboratory findings. Accurate assessment of pregnancy location is critical given that the mortality rate from interstitial pregnancies is twice that of other ectopics. In contrast, live birth rates for eccentric intracavitary pregnancies may be up to 69%, and some clinicians consider expectant management of asymptomatic patients in the first trimester.

INTERVENTION

The patient was recommended for inpatient admission with expedited surgical management of interstitial ectopic pregnancy. On laparoscopic entry, the pregnancy was not well-visualized because it did not deform the uterine serosa.

MAIN OUTCOME MEASURES

We present a surgical approach to suspected interstitial ectopic pregnancy that is not well-visualized at the time of laparoscopy.

RESULTS

The following principles are explored: the use of multiple minimally invasive modalities (laparoscopy and hysteroscopy) to perform a thorough evaluation of the pregnancy location; incorporation of intraoperative ultrasound; temporary vessel ligation and injection of intramyometrial vasopressin; complete enucleation of the products of conception; and closure of the myometrial defect.

CONCLUSION

We emphasize the benefits of a multidisciplinary approach for the localization and resection of interstitial ectopic pregnancy. This patient was discharged home in good condition with no complications.

Salpingo-oophorectomy or surveillance for ovarian endometrioma in asymptomatic premenopausal women: a cost-effectiveness analysis

BACKGROUND

The lifetime risk of ovarian cancer is 1.9% among women with endometriosis compared with 1.3% among the general population. When an asymptomatic endometrioma is incidentally discovered on imaging, gynecologists must weigh the procedural complications and the potential for subsequent surgical menopause against future ovarian pathology or cancer.

OBJECTIVE

We aimed to determine if performing unilateral salpingo-oophorectomy is a more cost-effective strategy for the prevention of death than surveillance for asymptomatic endometriomas.

STUDY DESIGN

We created a cost-effectiveness model using TreeAge Pro (TreeAge Software Inc; Williamstown, MA) with a lifetime horizon. Our hypothetical cohort included premenopausal patients with 2 ovaries who did not desire fertility. Those diagnosed with asymptomatic endometrioma underwent either unilateral salpingo-oophorectomy or surveillance (ultrasound 6-12 weeks after diagnosis, then annually). Our primary effectiveness outcome was mortality, including death from ovarian cancer or surgery and all-cause mortality related to surgical menopause (± hormone replacement therapy) if the contralateral ovary is removed. We modeled the probabilities of surgical complications, occult malignancy, development of contralateral adnexal pathology, surgical menopause, use of hormone replacement therapy, and development of ovarian cancer. The costs included surgical procedures, complications, ultrasound surveillance, hormone therapy, and treatment of ovarian cancer, with information gathered from Medicare reimbursement data and published literature. Cost-effectiveness was determined using the incremental cost-effectiveness ratio of Δ costs / Δ deaths with a willingness-to-pay threshold of $11.6 million as the value of a statistical life. Multiple 1-way sensitivity analyses were performed to evaluate model robustness.

RESULTS

Our model demonstrated that unilateral salpingo-oophorectomy is associated with improved outcomes compared with surveillance, with fewer deaths (0.28% vs 1.50%) and fewer cases of ovarian cancer (0.42% vs 2.96%). However, it costs more than sonographic surveillance at $6403.43 vs $5381.39 per case of incidental endometrioma. The incremental cost-effectiveness ratio showed that unilateral salpingo-oophorectomy costs $83,773.77 per death prevented and $40,237.80 per case of ovarian cancer prevented. As both values were well below the willingness-to-pay threshold, unilateral salpingo-oophorectomy is cost-effective and is the preferred strategy. If unilateral salpingo-oophorectomy were chosen over surveillance for premenopausal patients with incidental endometriomas, 1 diagnosis of ovarian cancer would be prevented in every 40 patients and 1 death averted in every 82 patients. We performed 1-way sensitivity analyses for all input variables and determined that there were no reasonable inputs that would alter our conclusions.

CONCLUSION

Unilateral salpingo-oophorectomy is cost-effective and is the preferred strategy compared with surveillance for the management of incidental endometrioma in a premenopausal patient not desiring fertility. It incurs fewer deaths and fewer cases of ovarian cancer with costs below the national willingness-to-pay thresholds.

Endometrial Sampling for Preoperative Diagnosis of Uterine Leiomyosarcoma

STUDY OBJECTIVES

To examine the effectiveness of endometrial sampling for preoperative detection of uterine leiomyosarcoma in women undergoing hysterectomy, identify factors associated with missed diagnosis, and compare the outcomes of patients who had a preoperative diagnosis with those of patients who had a missed diagnosis.

DESIGN

Retrospective cohort study using linked data from the New York Statewide Planning and Research Cooperative System and New York State Cancer Registry from 2003 to 2015.

SETTING

Inpatient and outpatient encounters at civilian hospitals and ambulatory surgery centers in New York State.

PATIENTS

Women with uterine leiomyosarcoma who underwent a hysterectomy and a preoperative endometrial sampling within 90 days before the hysterectomy.

INTERVENTIONS

Endometrial sampling.

MEASUREMENTS AND MAIN RESULTS

A total of 79 patients with uterine leiomyosarcoma met the sample eligibility criteria. Of these patients, 46 (58.2%) were diagnosed preoperatively, and 33 (41.8%) were diagnosed postoperatively. Patients in the 2 groups did not differ significantly in age, race/ethnicity, bleeding symptoms, or comorbidities assessed. In multivariable regression analysis, women who had endometrial sampling performed with hysteroscopy (compared with women who had endeometrial sampling performed without hysteroscopy) had a higher likelihood of preoperative diagnosis (adjusted risk ratio [aRR] 3.03; 95% confidence interval [CI], 1.43-6.42). Patients with localized stage (vs distant stage) or tumor size >11 cm (vs <8 cm) were less likely to be diagnosed preoperatively (aRR 0.50; 95% CI, 0.28-0.89, and aRR 0.54; 95% CI, 0.30-0.99, respectively). Supracervical hysterectomy was not performed in any of the patients whose leiomyosarcoma was diagnosed preoperatively compared with 21.2% of the patients who were diagnosed postoperatively (p = .002).

CONCLUSION

Endometrial sampling detected leiomyosarcoma preoperatively in 58.2% of the patients. The use of hysteroscopy with endometrial sampling improved preoperative detection of leiomyosarcoma by threefold. Patients with a missed diagnosis had a higher risk of undergoing suboptimal surgical management at the time of their index surgery.

Perioperative outcomes in a nationwide sample of patients undergoing surgical treatment of ovarian endometriomas

OBJECTIVE

To evaluate the perioperative outcomes of premenopausal women undergoing cystectomy or oophorectomy for ovarian endometriomas (OMAs) and other benign neoplasms.

DESIGN

Retrospective cohort study.

SETTING

Clinical database containing information from 580 US hospitals.

PATIENT(S)

Women 18 to 50 years old who underwent ovarian cystectomy or oophorectomy for benign indications between 2010 and 2020.

INTERVENTION(S)

We compared procedure route, length of hospital stay, and complication rates by surgical indication (OMA vs. other benign neoplasms) and surgical procedure (cystectomy vs. oophorectomy).

MAIN OUTCOME MEASURE(S)

Thirty-day perioperative adverse events following adnexal surgery, including conversion to laparotomy, blood transfusion, ileus, urinary tract injury, bowel injury, readmission, and death.

RESULT(S)

We identified 120,208 ovarian cystectomies (28,182 OMAs and 92,026 other indications) and 53,476 oophorectomies (8,622 OMAs and 44,854 other indications). During cystectomy, patients with OMAs more commonly experienced conversion to laparotomy (5.1% vs. 3.1%) and readmission (8.5% vs. 7.1%). For oophorectomies, patients with OMAs less frequently had minimally invasive surgery (55.8% vs. 64.8%) or outpatient procedures (33.8% vs. 41.8%). Urinary tract and bowel injuries were rare. Multivariable logistic regression demonstrated that the presence of OMA predicted composite complications during cystectomy (adjusted odds ratio [aOR] 1.23, 95% confidence interval [CI] 1.18-1.28) but not during oophorectomy (aOR 1.05, 95% CI 0.99-1.12). Patients with OMAs had 1.37 times the odds of a composite complication during oophorectomy than during cystectomy (95% CI 1.28-1.47).

CONCLUSION(S)

Patients undergoing ovarian cystectomy for OMAs had higher rates of perioperative adverse events than patients undergoing ovarian cystectomy for other benign neoplasms. Laparotomies were performed more often during oophorectomies for OMAs than for other benign indications.

The Large Uterus Classification System: a prospective observational study

Objective

To investigate the Large Uterus Classification System (LUCS) ability to predict surgical outcomes and complications in total laparoscopic hysterectomies (TLHs) for large uteri.

Design

Prospective observational study.

Setting

Two referral centres.

Population or sample

Three hundred and ninety‐two women who underwent TLH for a large uterus (uterine fundus at or over the transverse umbilical line).

Methods

Between 2004 and 2019, the intraoperative LUCS was estimated in all patients. The LUCS considers the uterine and adnexal vascular pedicles displacement. Type 1 is without vascular pedicles displacement. Type 2 has the cephalad displacement of adnexal vascular pedicles. The uterine vessels displacement regardless of adnexal pedicles defines Type 3.

Main outcome measures

Patients’ characteristics with perioperative outcomes were prospectively collected and compared between the three types of large uteri.

Results

Two hundred and fifty‐one (64%), 82 (20.9%) and 59 (15.1%) women had Type 1, Type 2 and Type 3 uteri, respectively. Women with Type 1 uteri had a lower uterine weight, shorter operative time, less blood loss and lower complication rates than women with Types 2 and 3. The conversion rate to laparotomy in Type 1 was similar to that in Type 2 (odds ratio [OR] 0.98; 95% CI 0.32–3.56) but lower than Type 3 (OR 0.35; 95% CI 0.14–0.97); in Type 2 it was lower than Type 3, although without the conventional statistical significance (OR 0.36; 95% CI 0.13–1.13; P = 0.07). Multivariable analysis showed that the uterine Type (1 versus 2–3) was independently associated with the total complications rate (OR 2.00; 95% CI 1.09–3.68; P = 0.02).

Conclusions

The LUCS appears associated with surgical outcomes and complications, potentially stratifying the surgical risk and guiding the surgical technique in TLHs for large uteri.

Vaginal surgery: don't get bent out of shape

Vaginal hysterectomy rates in the United States are decreasing, despite it being the recommended hysterectomy route for benign hysterectomy by multiple societies. Visualization issues are a known barrier to a medical student learning in the operating room, and it is likely that this also extends to resident training. In addition, vaginal surgery can be taxing on both the surgeons and assistants, with high rates of musculoskeletal work disorders reported in vaginal surgeons. The use of a camera is integral to endoscopic surgery, and table-mounted retractor systems have been used for decades in open surgery. We bring these 2 features into vaginal surgery, that is, using a table-mounted camera system and a table-mounted vaginal retractor. When used together as demonstrated in this video, these tools can improve visualization and may improve ergonomics for the entire surgical team, including learners, during vaginal surgery.

Endometriosis and the Urinary Tract: From Diagnosis to Surgical Treatment

We aim to describe the diagnosis and surgical management of urinary tract endometriosis (UTE). We detail current diagnostic tools, including advanced transvaginal ultrasound, magnetic resonance imaging, and surgical diagnostic tools such as cystourethroscopy. While discussing surgical treatment options, we emphasize the importance of an interdisciplinary team for complex cases that involve the urinary tract. While bladder deep endometriosis (DE) is more straightforward in its surgical treatment, ureteral DE requires a high level of surgical skill. Specialists should be aware of the important entity of UTE, due to the serious health implications for women. When UTE exists, it is important to work within an interdisciplinary radiological and surgical team.

Feasibility and Outcomes of Opportunistic Bilateral Salpingectomy in Patients with Traditional Relative Contraindications to Vaginal Hysterectomy

STUDY OBJECTIVE

To compare the feasibility of opportunistic bilateral salpingectomy (OBS) at the time of vaginal hysterectomy (VH) for benign disease in patients with and without relative contraindications (RCs) to the vaginal approach and to evaluate the factors that contribute to the inability to perform OBS.

DESIGN

Retrospective chart review.

SETTING

Tertiary medical center.

PATIENTS

Women undergoing hysterectomy for benign indications between November 2014 and October 2017 who were consented for either VH with or without removal of tube(s) and/or bilateral salpingectomy.

INTERVENTIONS

RCs to the vaginal approach are defined as lack of prolapse (cervix high, cervix not visualized, cervix tucked underneath pubis, or minimal descent), enlarged uterus (≥250 g or a size of a ≥12-week uterus), nulliparity, obesity (body mass index ≥30 kg/m²), previous cesarean section (CS), known adhesions, and known adnexal pathologic condition.

MEASUREMENTS AND MAIN RESULTS

A total of 258 patients underwent VH and attempted to undergo OBS within the study period; of these, 112 patients (43.4%) had no RC, and 146 patients (56.6%) had ≥1 RCs. Overall, successful salpingectomy was performed in 86.8% of patients. There was no significant difference in the rate of success in patients without or with ≥1 RCs (84.9% vs 89%, p = .15). Salpingectomy was unsuccessful in 13.2% of patients (n = 34). In a multivariable logistic regression analysis, the odds of unsuccessful OBS were 3.83 times higher in patients without prolapse (confidence interval [CI], 0.99-14.76; p = .051), 2.71 times higher in patients with obesity (CI, 1.23-5.94; p = .013), and 3.07 times higher in patients with previous CS (CI, 1.17-8.08; p = .023) as compared to patients without any relative contraindications. An enlarged uterus was associated with successful salpingectomy (odds ratio, 0.28; 95% CI, 0.08-0.94; p = .039) compared with a normal-sized uterus. When excluding enlarged uterus, patients with 2 to 3 RCs had 11.24 and 6.8 higher odds of an unsuccessful OBS than patients with no (CI, 3.73-33.87; p <.001) and 1 RC (CI, 2.36-19.63; p <.001), respectively. There were no differences in postoperative stay or rates of readmission among patients with or without successful salpingectomy at the time of VH.

CONCLUSION

OBS is associated with a high overall rate of success in patients with and without traditional RCs to VH. Lack of prolapse, obesity, and previous CS were associated with failed attempt at salpingectomy. Patients with ≥2 RCs to VH should be counseled about the high likelihood of failed salpingectomy.

Perioperative Interventions to Minimize Blood Loss at the Time of Hysterectomy for Uterine Leiomyomas: A Systematic Review and Meta-analysis

STUDY OBJECTIVE

Hysterectomy for uterine leiomyoma(s) is associated with significant morbidity including blood loss. A systematic review and meta-analysis was conducted to identify nonhormonal interventions, perioperative surgical interventions, and devices to minimize blood loss at the time of hysterectomy for leiomyoma.

DATA SOURCES

Librarian-led search of Embase, MEDLINE, Web of Science, Scopus, Cumulative Index to Nursing and Allied Health Literature, and Cochrane databases from 1946 to 2018 with hand-guided updates.

METHODS OF STUDY SELECTION

Included studies reported on keywords of hysterectomy, leiomyoma, and operative blood loss/postoperative hemorrhage/uterine bleeding/metrorrhagia/hematoma. The review excluded a comparison of route of hysterectomy, morcellation, vaginal cuff closure, hormonal medications, vessel sealing devices for vaginal hysterectomy, and case series with <10 patients.

TABULATION, INTEGRATION, AND RESULTS

Surgical blood loss, postoperative hemoglobin (Hb) drop, hemorrhage, transfusion, and major and minor complications were analyzed and aggregated in meta-analyses for comparable studies in each category. A total of 2016 unique studies were identified, 33 of which met the inclusion criteria, and 22 were used for quantitative synthesis. The perioperative use of misoprostol in abdominal hysterectomy (AH) was associated with a lower postoperative Hb drop (0.59 g/dL; 95% confidence interval [CI], 0.39-0.79; p < .01) and blood loss (-96.43 mL; 95% CI, -153.52 to -39.34; p < .01) compared with placebo. Securing the uterine vessels at their origin in laparoscopic hysterectomy (LH) was associated with decreased intraoperative blood loss (-69.07 mL; 95% CI, -135.20 to -2.95; p = .04) but no significant change in postoperative Hb (0.24 g/dL; 95% CI, -0.31 to 0.78; p = .39) compared with securing them by the uterine isthmus. Uterine artery ligation in LH before dissecting the ovarian/utero-ovarian vessels was associated with lower surgical blood loss compared with standard ligation (-27.72 mL; 95% CI, -35.07 to -20.38; p < .01). The postoperative Hb drop was not significantly different with a bipolar electrosurgical device versus suturing in AH (0.26 g/dL; 95% CI, -0.19 to 0.71; p = .26). There was no significant difference between an electrosurgical bipolar vessel sealer (EBVS) and conventional bipolar electrosurgical devices in the Hb drop (0.02 g/dL; 95% CI, -0.15 to 0.20; p = .79) or blood loss (-50.88 mL; 95% CI, -106.44 to 4.68; p = .07) in LH. Blood loss in LH was not decreased with the LigaSure (Medtronic, Minneapolis, MN) impedance monitoring EBVS compared with competing EBVS systems monitoring impedance or temperature (2.00 mL; 95% CI, -8.09 to 12.09; p = .70). No significant differences in hemorrhage, transfusion, or major complications were noted for all interventions.

CONCLUSION

Perioperative misoprostol in AH led to a reduction in surgical blood loss and postoperative Hb drop (moderate level of evidence by Grading of Recommendations, Assessment, Development and Evaluation guidelines) although the clinical benefit is likely limited. Remaining interventions, although promising, had at best low-quality evidence to support their use at this time. Larger and rigorously designed randomized trials are needed to establish the optimal set of perioperative interventions for use in hysterectomy for leiomyomas.

Is High-intensity Focused Ultrasound Effective for the Treatment of Adenomyosis? A Systematic Review and Meta-analysis

STUDY OBJECTIVE

To systematically review the literature regarding the efficacy of high-intensity focused ultrasound (HIFU) in reducing adenomyotic lesions, patients' pain and bleeding symptoms, and the impact on patients' quality of life.

DATA SOURCE

A search was performed through PubMed/MEDLINE and Cochrane databases.

METHODS OF STUDY SELECTION

All available studies published in the English language in the last 10 years that evaluated the effects of HIFU for adenomyosis.

TABULATION, INTEGRATION, AND RESULTS

A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A meta-analysis was performed on data from homogeneous studies. Pooled results from the meta-analysis showed that after HIFU treatment for adenomyosis, a large effect was observed in reducing the uterine volume at 12 months (standard mean difference [SMD] = 0.85), a significant reduction in dysmenorrhea at 3 months (SMD = 1.83) and 12 months (SMD = 2.37), and a significant improvement in quality of life at 6 months (SMD = 3.0) and 12 months (SMD = 2.75). Adverse reactions after HIFU were reported in 55.9% of patients.

CONCLUSION

This review suggests a potential benefit for HIFU in the treatment of adenomyosis-related symptoms; however, findings of the meta-analysis were based on fewer, nonuniform studies, which did not equally account for each specific symptom/parameter across the board. Results showed there appears to be a potential of HIFU in the treatment of adenomyosis-related symptoms. To date, there are no comparative and randomized clinical trials comparing the HIFU technique with other conservative treatment options. As yet, there are insufficient data regarding fertility and pregnancy outcomes.

Structured Ultrasound and Magnetic Resonance Imaging Reports for Patients with Suspected Endometriosis: Guide for Imagers and Clinicians

In this article we propose a structured imaging report applied to ultrasound and magnetic resonance imaging in patients with suspected endometriosis.

Evaluation of Positioning Devices for Optimization of Outcomes in Laparoscopic and Robotic-Assisted Gynecologic Surgery

In this review, we evaluate techniques, devices, and equipment for patient positioning and their effect on patient outcomes, such as cephalad slide and neuropathy, in laparoscopic and robotic-assisted gynecologic surgery. We conducted a systematic review by searching MEDLINE, Embase, and Cochrane Library for relevant articles published over a 15-year period. Study selection, data extraction, and quality assessment were performed by 2 reviewers independently. Seven articles, including 3 randomized controlled trials and 4 case series, were included in our analysis. Four studies evaluated cephalad patient slide. In 2 randomized controlled trials (n = 103), the mean slide with various devices (i.e., memory foam, bean bag with shoulder braces, egg crate, and gel pad) ranged from 1.07 ± 1.93 cm to 4.5 ± 4.0 cm. The use of a bean bag with shoulder supports/braces was associated with minimal slide, with a median slide of 0 cm (range, 0-2 cm) in a retrospective series and with mean slide of 1.07 ± 1.93 cm in a randomized controlled trial (vs memory foam). No conclusive effect of body mass index on slide could be identified. Five studies evaluating the incidence of neuropathy found an overall incidence of 0.16% and no differences among slide-preventing devices. The minimal slide described across studies supports the conclusion that any of the currently used devices and techniques for safe patient positioning are within reason. The low overall incidence of neuropathy is also reassuring. Best evidence recommendations cannot be made for a specific device or technique; our findings suggest the importance of strict adherence to the basic tenets of safe patient positioning to minimize slide and prevent nerve injury.

The current management of deep endometriosis: a systematic review

INTRODUCTION

Endometriosis is a chronic inflammatory disease that affects young women in reproductive age. It has mainly three different clinical presentations: superficial (peritoneal), ovarian (endometriomas) and deep endometriosis (DE). The last one is the most advanced form of the disease, frequently impairing fertility and harming women's quality of life (QoL).

EVIDENCE ACQUISITION

We conducted a systematic review on the surgical treatment of DE in the last ten years focusing on its benefits to improve QoL and for pain relief as well as related surgical complications.

EVIDENCE SYNTHESIS

Twenty-three studies were included for qualitative analysis. Overall, included studies showed a relevant improvement in QoL as well as in pain scores using specific questionnaires and the ten-point Visual Analogue Scale (VAS) for pain.

CONCLUSIONS

Until further comparative studies regarding medical versus surgical treatment for DE are concluded, currently, surgery is the best option for patients with DE and severe pain (VAS>7).

Role of Imaging Tools for the Diagnosis of Borderline Ovarian Tumors: A Systematic Review and Meta-Analysis

Borderline ovarian tumors (BOTs) have a low malignant potential and occur most often in young women. Its preoperative diagnosis can improve surgical strategy and reproductive approach. This study systematically reviews the literature for the accuracy of transvaginal ultrasound (TVUS), magnetic resonance (MRI), and computed tomography (CT) in the diagnostic of BOTs. We conducted a search in PubMed/Medline of articles in English from the last 5 years and included 14 studies for systematic review, 9 of them in the meta-analysis. The pooled sensibility and specificity was respectively 77.0% and 83.0% for TVUS (5 studies) and 85% and 74% for MRI (4 studies) in differentiating benign from malignant BOTs. CT and positron emission tomography (PET)-CT techniques were heterogeneous between studies, so a meta-analysis was not performed for the 4 studies on CT and PET-CT. However, these 4 studies have also shown a high accuracy in differentiating BOTs from malignant ovarian cancers.

Ten Principles for Safe Surgical Treatment of Ovarian Endometriosis

STUDY OBJECTIVE

To show a step-by-step laparoscopic approach for excision of an ovarian endometrioma following surgical principles for safety and maximal preservation of ovarian function.

DESIGN

Video. Medical management of ovarian endometriomas is not recommended. Operative laparoscopy is the treatment of choice. Although considered a simple procedure, ovarian cystectomy requires a precise and correct technique in order to preserve ovarian function.

SETTING

A private hospital.

PATIENT

An asymptomatic, 27-year-old woman with ultrasound imaging suggesting a 6.2 × 5.4 cm left endometrioma. Additional findings of endometriotic implants were noted in the posterior aspect of the left broad ligament, retrocervical region, Douglas pouch, and left round ligament.

INTERVENTIONS

After trocar insertion, standard inspection of the pelvic cavity with identification of endometriosis lesions and adhesions was performed. The endometrioma was drained with direct trocar puncture to avoid spillage of the endometriotic contents. Cyst aspiration and saline cleaning were executed. After drainage, a cold cut was performed at the puncture site for better identification of the cyst capsule. Through gentle traction and countertraction, the capsule was peeled from the ovarian cortex, preserving as much ovarian tissue as possible followed by careful hemostasis with a bipolar instrument. The ovary is fixed, anatomy re-established, and concomitant pelvic endometriosis resected. We aim for complete surgical excision in order to avoid leaving disease behind. The ovarian edges were reapproximated using simple interrupted stitches.

MEASUREMENTS AND MAIN RESULTS

The total procedure time was 40 minutes.

CONCLUSION

Laparoscopic endometrioma stripping offers an effective option for ovarian endometriosis treatment, reducing recurrence and being reproducible by gynecologic surgeons after proper training.

Round Ligament Technique and Use of a Vessel-sealing Device to Facilitate Complete Salpingectomy at the Time of Vaginal Hysterectomy

Prophylactic salpingectomy at the time of hysterectomy has been recommended for women at average risk for ovarian cancer. Vaginal hysterectomy is considered the preferred approach to a benign hysterectomy, and adnexectomy should not be considered a contraindication to this approach. This paper with accompanying video describes and demonstrates the round ligament technique and use of a vessel-sealing device to facilitate removal of the entire fallopian tube at the time of vaginal hysterectomy.

Cellular, histologic, and molecular changes associated with endometriosis and ovarian cancer

Our understanding of the pathogenesis of endometriosis is rapidly evolving as early molecular events are increasingly identified. Endometriosis is associated with increased risk of ovarian cancer and exhibits neoplastic phenotypes including invasion of stromal tissue and lymphatic spread to distant organs. This review of the literature establishes the clinical, epidemiologic, and pathologic correlation between endometriosis and low-grade ovarian cancer. Genetic studies have demonstrated that endometriotic lesions have mutations in genes directly related to neoplasms, in particular the p53, KRAS, PTEN, and ARID1A genes, which suggests a direct transition from a subset of endometriotic lesions to invasive carcinomas. The identification of both genetic and epigenetic biomarkers including microRNAs are essential for identifying patients at risk for the transition to neoplasia.

Leiomyoma-related hospitalization and surgery: prevalence and predicted growth based on population trends

OBJECTIVE

To estimate leiomyoma-related inpatient care in the United States for 2007 with predictions for the ensuing 40 years.

STUDY DESIGN

We used the 2007 Nationwide Inpatient Sample to estimate hospitalizations and inpatient surgeries for uterine leiomyoma in US women 15 to 54 years. We used the US Census Bureau population projections to predict leiomyoma-related inpatient care through 2050.

RESULTS

In 2007, 355,135 women were hospitalized for leiomyoma (rate = 42 per 10,000 women-years). Black women had increased rates of hospitalization, hysterectomy, and myomectomy (relative risk, 3.5, 2.4, 6.8, respectively) compared with white women. Leiomyoma-related hospitalizations are predicted to increase 23% (to 437,874) between 2007 and 2050, with 20% and 31% increases in leiomyoma-related hysterectomies and myomectomies.

CONCLUSION

Leiomyoma-related inpatient care and major surgery remains substantial despite advances in less invasive treatment options. Given population growth, the projected burden of leiomyoma-related inpatient care will increase significantly by 2050, differentially impacting black vs white women.

Removal of the retained cervical stump after supracervical hysterectomy

Current studies do not support any benefit of supracervical hysterectomy in reducing perioperative morbidity and adverse effects on pelvic support, sexual and urinary function. Prolapse, pelvic mass and bleeding were the most common indications for trachelectomy after supracervical hysterectomy. Vaginal trachelectomy was the preferred approach to the procedure involving the least complications.

Comparison of robotic and laparoscopic myomectomy

OBJECTIVE

To compare surgical outcomes of patients with symptomatic leiomyomas after robot-assisted ("robotic") or laparoscopic myomectomy.

STUDY DESIGN

Retrospective chart review of 81 patients undergoing robotic (n=40) or laparoscopic (n=41) myomectomy. Data included fibroid characteristics (number, weight, location, and pathologic findings), operating time, blood loss, complications, and postoperative hospitalization length.

RESULTS

Patients undergoing laparoscopy had a significantly larger mean uterine size, larger mean size of the largest fibroid, and greater number of fibroids. When adjusted for uterine size and fibroid size and number, no significant differences were noted between robotic vs laparoscopic groups for mean operating time (141 vs 166 minutes), mean blood loss (100 vs 250 mL), intraoperative or postoperative complications (2% vs 20% and 11% vs 17%, respectively), hospital stay more than 2 days (12% vs 23%), readmissions, or symptom resolution.

CONCLUSION

Short-term surgical outcomes were similar after robotic and laparoscopic myomectomy; long-term outcomes were not assessed.

Robotic appendectomy in gynaecological surgery: technique and pathological findings

BACKGROUND

We evaluated the feasibility, safety and pathological findings of incidental robotic appendectomy in patients undergoing robotic gynaecological surgery.

METHODS

Retrospective analysis of 107 consecutive cases of robotic appendectomy done in conjunction with other robotic gynaecological procedures between May 2004 and January 2007.

RESULTS

All appendectomies were performed robotically in conjunction with other robotic procedures. Mean time for appendectomy was 3.4 min. No perioperative complications related to appendectomy were encountered. Among 90 patients with no gynaecological malignancy, 57 patients reported chronic pelvic pain preoperatively and 21 (37%) of them had an abnormal appendiceal pathology as compared to only 5 (15%) of the 33 patients with no pelvic pain (OR. 3.2; 95% CI, 1.1-9.7, p = 0.032). Of seven patients with ovarian malignancy, three (42%) had appendicular metastasis.

CONCLUSION

Incidental robotic appendectomy can be performed safely without the need for switching to conventional laparoscopy. It should be considered in patients undergoing robotic pelvic surgery for pelvic pain and ovarian malignancy.
