RESUMO
STUDY OBJECTIVE: To identify the top 3 perceived barriers to performing office hysteroscopy (OH) by minimally invasive gynecologic surgery (MIGS) faculty and fellows and identify opportunities for education on this key topic that will be most effective in fellowship training and MIGS practice. DESIGN: Cross-sectional survey study targeted at all American Association of Gynecologic Laparoscopists-accredited Fellowship in Minimally Invasive Gynecologic Surgery fellows, program directors, and associate program directors in February to April 2022. The survey was designed by faculty who have extensive experience in OH procedures. In addition, a literature search was performed to aid with question design. SETTING, PATIENTS, AND INTERVENTIONS: This was a REDCap electronic survey administered through the Fellowship in Minimally Invasive Gynecologic Surgery listserv. No additional follow-up was performed after survey completion. The 15-minute survey was sent to 60 program directors, 92 assistant program directors, and 158 fellows, including the incoming class of 2024 and the 2022 fellowship graduates. MEASUREMENTS AND MAIN RESULTS: A total of 93 responses were received; 67% of respondents performed OH but 73% of those performed 5 procedures or less per month. Most participants controlled pain with nonsteroidal anti-inflammatory drugs +/- paracervical block. The most common perceived barrier to performing OH was concern over pain management. Other commonly cited concerns were equipment costs, sterilization costs, and office staff training; 37% to 44% of respondents also cited lack of departmental support and insufficient clinic time, respectively, as barriers, and 56% indicated they are interested in educational materials on OH. CONCLUSION: Our study suggests general interest in, but a low volume of, OH among MIGS fellows and faculty. The most common perceived barrier was concern regarding pain management. This has been well studied in the literature and likely presents an area for greater education to improve OH utilization. We also uncovered concerns regarding systemic barriers, such as equipment costs, departmental support, and clinic structure. This is an area for further research and advocacy efforts to address barriers to OH on a system level.

STUDY OBJECTIVES: To evaluate whether the use of radiofrequency energy during resectoscopy leads to increases in patient blood levels of carboxyhemoglobin (COHb) and investigate procedural variables associated with these elevations. DESIGN: A prospective cross-sectional study of 40 subjects undergoing a hysteroscopic procedure using bipolar radiofrequency energy. SETTING, PATIENTS, AND INTERVENTIONS: The study was conducted at an ambulatory surgery center. Procedures for uterine leiomyoma, septa, products of conception, or a combination of these pathologies were included. We measured blood COHb levels before and immediately after the surgery. Abnormal postoperative COHb level was defined as an increase of plasma COHb ≥3.0%. All patients with abnormal postoperative levels were contacted and screened for carbon monoxide toxicity symptoms. Summary statistics included frequency for categorical variables and averages for continuous variables. p values were reported without modification. MEASUREMENTS AND MAIN RESULTS: A total of 17.5% of subjects met the criteria for abnormal postoperative COHb levels. None of these subjects reported symptoms of carbon monoxide toxicity. One subject with an elevated postoperative COHb level had intraoperative hemodynamic changes possibly related to COHb elevation. An abnormal postoperative COHb level was associated with a higher fluid deficit (p = .024) and greater myoma volume (p = .04). CONCLUSION: This study demonstrates that systemic absorption of carbon monoxide is a reproducible phenomenon in hysteroscopic resections using bipolar diathermy. Greater absorption is associated with a higher fluid deficit and greater myoma volume. Although none of the subjects with an abnormal increase screened positive for symptoms in the postoperative setting and only 1 experienced hemodynamic changes intraoperatively, our study looked at a healthy and young patient population. More research is needed on the safety of this COHb exposure in patients with medical comorbidities. Special consideration should be given to the possibility of carbon monoxide absorption and the uncertain long-term effects when planning extensive hysteroscopic resections.

Objective: To determine quality-adjusted life years (QALYs) over 3 years after transcervical fibroid ablation (TFA) with the Sonata System. Methods: The SONATA trial was a prospective multicenter interventional trial that assessed the safety and efficacy of TFA for treatment of women with symptomatic uterine fibroids. Change in generic health status was assessed with the EuroQol 5-Dimension questionnaire (0-1 scale). Fibroid-specific quality of life (QOL) was measured on a 0 to 100 scale with the health-related quality of life subscale of the Uterine Fibroid Symptom and Quality-of-Life (UFS-QOL). The number of QALYs gained relative to baseline and cumulative QALYs were calculated using the area under the curve at each follow-up visit over 3 years. Results: Among 147 women receiving TFA, fibroid-specific QOL increased from 40 ± 21 at baseline to 84 ± 19 at 1 year and 83 ± 23 at 3 years (p < 0.001). Generic QOL increased from 0.72 ± 0.21 at baseline to 0.89 ± 0.12 at 1 year and 0.88 ± 0.16 at 3 years (p < 0.001). Over 3 years, TFA resulted in 1.24 ± 0.64 QALYs gained when using fibroid-specific health utility scores and 0.49 ± 0.61 QALYs gained when using generic health utility scores. Cumulative QALYs experienced at 3 years as a percentage of perfect health were 82% with fibroid-specific scores and 88% with generic health scores. Conclusions: Women treated by TFA with the Sonata System for symptomatic uterine fibroids reported durable improvements in generic and fibroid-specific QOL, as well as clinically meaningful increases in QALYs over 3 years.

RESUMO
BACKGROUND: Myomectomy is associated with a significant risk of hemorrhage. Tranexamic acid is a synthetic lysine derivative with antifibrinolytic activity used in other surgical disciplines to reduce blood loss during surgery. However, its utility in gynecologic surgery is not well understood. OBJECTIVE: This study aimed to determine the effect of early administration of intravenous tranexamic acid on perioperative bleeding and blood transfusion requirements in women undergoing myomectomy. STUDY DESIGN: This study was a double-blinded, randomized, placebo-controlled trial conducted in an academic teaching hospital. Women with symptomatic fibroids thought to be at risk for large intraoperative blood loss who met the following criteria were included in the study: (1) at least 1 fibroid ≥10 cm, (2) any intramural or broad ligament fibroid ≥6 cm, and/or (3) at least 5 total fibroids based on preoperative imaging. Patients were randomized to receive a single intravenous bolus injection of tranexamic acid 15 mg/kg (intervention group) versus an intravenous bolus injection of saline of equivalent volume (placebo group) 20 minutes before the initial surgical incision. Perioperative bleeding was defined by measuring intraoperative estimated blood loss, change between pre- and postoperative hemoglobin, and frequency of blood transfusions. Estimated blood loss was calculated by combining the blood volume collected within the suction canister and the weight of used sponges. The 2 groups were compared for age; body mass index; perioperative hemoglobin and hematocrit; perioperative blood loss; duration of surgery; blood transfusion requirements; and the number, total weight, and volume of myomas removed. RESULTS: A total of 60 patients (30 per arm) were enrolled into the study between March 1, 2015, and January 29, 2018. Age, body mass index, baseline hemoglobin and/or hematocrit, number and total weight of myomas removed, and size of myomas did not differ between arms. Of 60 patients, 32 (53%) had laparoscopic myomectomy, 24 (40%) had robotic myomectomy, and 4 (7%) had laparotomy. Median estimated blood loss was 200 mL for the tranexamic acid group and 240 mL for the placebo group (P=.88). There was no difference in median duration of surgery (165 vs 164 minutes; P=.64) or change in perioperative hemoglobin (1.00 vs 1.1 g/dL; P=.64). Patients in the tranexamic acid group did not require blood transfusions; however, 4 patients (13.3%) in the placebo group (P=.11) required blood transfusions. CONCLUSION: Intravenous administration of tranexamic acid in patients undergoing laparoscopic or robotic myomectomies was not associated with decreased blood loss.

Studies have demonstrated that during hysteroscopic myomectomy with bipolar diathermy, carbon monoxide is produced and enters the patient's circulation. However, little is known regarding the immediate or long-term sequelae of transient rises in carboxyhemoglobin levels during hysteroscopic surgery. This paper aims to suggest recommendations for acute evaluation, management, patient counseling, and future research. We present a case of a 36-year-old woman (Gravida 0, Para 0) with abnormal uterine bleeding-leiomyoma and resultant anemia, undergoing hysteroscopic resection of a large submucous myoma. During surgery, the patient was found to have a critically elevated level of carboxyhemoglobin and accompanying electrocardiogram derangements. She was managed with prolonged intubation, 100% O2, and trending of her carboxyhemoglobin levels before extubation. This demonstrates the importance of being cognizant of the potentially toxic gaseous byproducts of bipolar resection and of including intravasation of these byproducts in one's consideration of patient safety during extensive resections. Bipolar hysteroscopic resection of large leiomyomas may result in critically high carboxyhemoglobin levels, which can impair end-organ oxygen delivery with resultant ischemia; the risks of myocardial ischemia should be discussed with the anesthesia team before attempting an extensive resection. Electrocardiogram changes indicative of ischemia should prompt discontinuation of the case. Finally, carboxyhemoglobin poisoning should be included in the differential diagnosis of patients who demonstrate longer-than-expected anesthesia recovery times after bipolar resection of large submucous leiomyomas, and they should be managed with repeat evaluation of carboxyhemoglobin levels, supplemental oxygen, and cardiac monitoring.

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.

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.

Office hysteroscopy is a highly effective procedure for the evaluation and treatment of intrauterine pathology. The "see and treat" approach allows for patient treatment with the fewest amount of patient visits. The development of smaller cameras and instruments, as well as the employment of a vaginoscopy technique, has led to greater tolerability of office hysteroscopy and significant success of the "see and treat" approach. Most office hysteroscopic procedures can be accomplished with minimal premedication. There are many choices for equipment types and sterilization methods for the office hysteroscopy practice. Reimbursement for office hysteroscopy has improved, but economic challenges remain.

BACKGROUND AND OBJECTIVES: To assess the feasibility and safety of minimally invasive hysterectomy for uteri >1 kg. METHODS: Clinical and surgical characteristics were collected for patients in an academic tertiary care hospital. Included were patients who underwent minimally invasive hysterectomy by 1 of 3 fellowship-trained gynecologists from January 1, 2009, to July 1, 2015 and subsequently had confirmed uterine weights of 1 kg or greater on pathology report. Both robotic and conventional laparoscopic procedures were included. RESULTS: During the study period, 95 patients underwent minimally invasive hysterectomy with confirmed uterine weight over 1 kg. Eighty-eight percent were performed with conventional laparoscopy and 12.6% with robot-assisted laparoscopy. The median weight (range) was 1326 g (range, 1000-4800). The median estimated blood loss was 200 mL (range, 50-2000), and median operating time was 191 minutes (range, 75-478). Five cases were converted to laparotomy (5.2%). Four cases were converted secondary to hemorrhage and one secondary to extensive adhesions. There were no conversions after 2011. Intraoperative transfusion was given in 6.3% of cases and postoperative transfusion in 6.3% of cases. However, after 2013, the rate of intraoperative transfusion decreased to 1.0% and postoperative transfusion to 2.1%. Of the 95 cases, there were no cases with malignancy. CONCLUSIONS: This provides the largest case series of hysterectomy over 1 kg completed by a minimally invasive approach. Our complication rate improved with experience and was comparable to other studies of minimally invasive hysterectomy for large uteri. When performed by experienced surgeons, minimally invasive hysterectomy for uteri >1 kg can be considered feasible and safe.

OBJECTIVE: To evaluate postoperative blunt adhesiolysis after sharp adhesiolysis for the treatment of intrauterine adhesions. DESIGN: Retrospective analysis of 24 patients treated with primary hysteroscopic adhesiolysis followed by hormone therapy and serial flexible office hysteroscopy (Canadian Task Force Classification II-3). SETTING: University-affiliated community hospital. PATIENT(S): Twenty-four women with menstrual disorders, pain, or infertility resulting from intrauterine adhesions. INTERVENTION(S): Serial, postoperative, hysteroscopic blunt adhesiolysis of recurrent synechiae. MAIN OUTCOME MEASURE(S): Restoration of normal menstrual pattern, relief of dysmenorrhea, improvement in fertility, and improvement in stage of disease. RESULT(S): Eighty-three percent of patients (20/24) presented with amenorrhea or oligomenorrhea, 67% (16/24) had either infertility or recurrent miscarriages, and 54% (13/24) presented with dysmenorrhea. Initially, 50% (12/24) had severe adhesions, 46% (11/24) moderate, and 4% (1/24) minimal disease according to the March criteria. Improvement in menstrual flow occurred in 95% (18/19) of patients, relief of dysmenorrhea occurred in 92% (12/13), and 46% (7/15) of fertility patients were actively pregnant or had delivered viable infants at the conclusion of the study. There was a 92% (22/24) improvement in disease staging over the treatment interval. CONCLUSION(S): Blunt adhesiolysis with a flexible hysteroscope is effective for maintenance of cavity patency after primary treatment of intrauterine adhesions.

STUDY OBJECTIVE: To develop and evaluate the usefulness of a home-based laparoscopy practice tool in terms of skills acquisition and practice pattern. DESIGN: Six mirrored laparoscopy trainers were designed and built. Participants were enrolled in a prospective randomized controlled trial and performed a series of skills with a video-endoscopic training tower and laparoscopic training box in timed pre- and post-tests over 5 weeks. Control and experimental cohorts practiced skills tests in different settings with different equipment. Data analysis used the t test and Wilcoxon rank-sum test. Analysis of variance/analysis of covariance models were used for independent variables. (Canadian Task Force classification I.) SETTING: Midwestern tertiary care teaching hospital. PARTICIPANTS: Third-year medical students rotating through their obstetrics and gynecology clerkship. INTERVENTIONS: Control cohort participants (n = 13) practiced the skills in the video-endoscopic laboratory while the experimental cohort (n = 13) received mirrored training boxes and practiced at home. MEASUREMENTS AND MAIN RESULTS: Both groups demonstrated significant improvement, with a trend favoring the control group (p = .08). Randomization group and number of practice sessions were significant variables favoring the control group and experimental group, respectively. CONCLUSION: Home-based practice on a mirrored laparoscopy trainer improves hand-eye coordination in inexperienced surgeons and results in more frequent practice.
