Diagnosis of gynecologic malignancy after the treatment of presumed benign fibroid disease with interventional radiology procedures: a retrospective cohort study.

OBJECTIVE: To ascertain the finding of future diagnosis of malignancy in women who undergo nonsurgical treatment for uterine fibroid disease with interventional radiology (IR) procedures. DESIGN: Mixed-methods retrospective cohort study. SETTING: Two tertiary care academic hospitals in Boston, Massachusetts. PATIENT(S): A total of 491 women who underwent radiologic intervention for fibroids between 2006 and 2016. INTERVENTION(S): Uterine artery embolization or high-intensity focused ultrasound ablation. MAIN OUTCOME MEASURE(S): Subsequent surgical interventions and diagnosis of gynecologic malignancy after the IR procedure. RESULT(S): During the study period, 491 women underwent treatment of fibroids with IR procedures; follow-up information was available for 346 cases. The mean age was 45.3 ± 4.8 years, and 69.7% were between the ages of 40 and 49 years. Regarding ethnicity, 58.9% of patients were white, and 26.1% were black. The most common symptoms were abnormal uterine bleeding (87%), pelvic pressure (62.3%), and pelvic pain (60.9%). A total of 106 patients underwent subsequent surgical treatment of fibroids. Of the 346 patients who had follow-up, 4 (1.2%) were diagnosed with leiomyosarcoma after their interventional treatment for fibroids. An additional 2 cases of endometrial adenocarcinoma and 1 case of a premalignant lesion of the endometrium were noted. CONCLUSION(S): The proportion of patients who went on to be diagnosed with leiomyosarcoma after conservative IR treatments appears to be higher than previously reported. A thorough preprocedural workup and patient counseling regarding the possibility of underlying uterine malignancy should be undertaken.

Oxycodone Use During the Postoperative Period After Hysterectomy for Benign Indications.

OBJECTIVES: The objective of this study was to estimate the amount of oxycodone tablets required for pain control in the 2-week postoperative period after laparoscopic hysterectomy (LH) and vaginal hysterectomy (VH) for benign disease. METHODS: We conducted a prospective cohort study of English-speaking women 18 years or older undergoing hysterectomy for benign indications. Participants completed a pain survey at baseline and daily for 2 weeks postoperatively. In addition, they recorded the number of oxycodone tablets and other pain medications taken daily for 2 weeks. The primary outcome was the median number of oxycodone tablets (5 mg) consumed after LH or VH during 2 weeks postoperative. RESULTS: Eighty-one women underwent VH and 82 underwent LH. Women who underwent VH were older (mean ± SD, 64.2 ± 10.3 years vs 47.5 ± 7.7 years), more parous (2 [interquartile range (IQR), 2-3] vs 2 [IQR, 1-2]), and less likely to be sexually active (51.9% vs 79.3%, P < 0.02). Women in the VH group also had significantly lower baseline pain levels (0 [IQR, 0-1] vs 1 [IQR, 0-4], P < 0.001). All VH participants had surgery for prolapse, whereas only 12.2% in the LH group had surgery for this indication (P < 0.001). Most in the LH group had surgery for fibroids (61%) or abnormal uterine bleeding (15.9%). Women in the VH group consumed significantly less oxycodone tablets postoperatively (median, 4.5 [IQR, 1-9] vs 7 [IQR, 2-18]; P = 0.047) and took oxycodone for less days after discharge (median, 1 [IQR, 0-3] vs 3 [IQR, 1-6]; P < 0.001). CONCLUSIONS: Women consume less oxycodone after minimally invasive hysterectomy than previously thought. Those who undergo VH may consume less oxycodone than those who undergo LH.

Superior Hypogastric Plexus Block to Reduce Pain After Laparoscopic Hysterectomy: A Randomized Controlled Trial.

OBJECTIVE: To assess whether a superior hypogastric plexus block performed during laparoscopic hysterectomy reduces postoperative pain. METHODS: We conducted a multicenter, randomized, single-blind, controlled trial of superior hypogastric plexus block at the start of laparoscopic hysterectomy. Women undergoing a laparoscopic hysterectomy for any indication and with any other concomitant laparoscopic procedure were eligible. Standardized preoperative medications and incisional analgesia were provided to all patients. Our primary outcome was the proportion of patients with a mean visual analog scale (VAS) pain score lower than 4 within 2 hours postoperatively. Patients but not surgeons were blinded to the treatment group. Twenty-nine patients per group was estimated to be sufficient to detect a 38% absolute difference in the proportion of patients with a VAS score lower than 4 at 2 hours postoperatively, with 80% power and an α of 0.05. To account for loss to follow-up and potential imbalances in patient characteristics, we planned to enroll 50 patients per group. All analyses were intention to treat. RESULTS: Between January 2018 and February 2019, 186 patients were eligible; 100 were randomized and analyzed. Demographic and clinical characteristics were similar between the two groups. There was no significant difference in the proportion of patients with a mean VAS score lower than 4 within 2 hours postoperatively between patients who received a superior hypogastric plexus block (57%) and patients who did not (43%) (odds ratio 1.63, 95% CI 0.74-3.59; adjusted odds ratio 1.84, 95% CI 0.75-4.51). CONCLUSION: Among patients undergoing laparoscopic hysterectomy with standardized enhanced perioperative recovery pathways, superior hypogastric plexus block did not significantly reduce postoperative pain. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT03283436.

Triaging abnormal cervical cancer screening tests using p16INK4a detection by ELISA on fresh cervical samples.

PROBLEM: Cervical cancer screening strategies in the United States include cotesting (human papillomavirus (HPV) with cytology), primary HPV with genotyping and reflex cytology, and cytology alone. An ongoing challenge is the appropriate triage of patients to colposcopy to those at highest risk. We investigated whether incorporation of p16INK4a immunodetection by enzyme-linked immunosorbent assay (ELISA) on fresh cervical samples obtained at the time of screening could improve appropriate referral to colposcopy. METHOD OF STUDY: A derivation group comprised of cervical swabs collected from subjects with high-grade dysplasia or cancer (positive control) and from subjects with negative screening history (negative control). Samples collected from colposcopy were used to evaluate the existing screening strategies individually and with incorporation of p16INK4a ELISA. Histology was used as the gold standard. RESULTS: Among 163 subjects recruited, 138 were included. In the derivation group, mean p16INK4a level was 2.86 ng/mL (n = 31) and 0.58 ng/mL (n = 20) among positive and negative controls respectively (p = 0.002) with an area under the receiver operator characteristic curve of 0.79 (p < 0.001). Among colposcopy subjects, sensitivity/specificity for cotesting, primary HPV, and cytology were 94%/42%, 88%/45%, and 88%/49%, respectively. Incorporation of p16INK4a resulted in similar sensitivity and improved specificity (cotesting+p16 88%/58%, primary HPV+p16 88%/57%, cytology+p16 81%/62%; p = 0.23/p = 0.008) with decrease in colposcopy referrals by 15% to 22% (p = 0.01). CONCLUSIONS: These results demonstrate the feasibility of quantifying p16INK4a by ELISA in fresh cervical samples, and its potential as an adjunct to existing screening strategies in the identification of high grade-dysplasia while reducing the number of colposcopic referrals.

Peri- and Postoperative Outcomes of Outpatient vs Inpatient Laparoscopic Apical Prolapse Repair.

STUDY OBJECTIVE: To assess the feasibility of outpatient laparoscopic management of apical pelvic organ prolapse along with indicated vaginal repairs and anti-incontinence procedures. DESIGN: Retrospective cohort study. SETTING: Tertiary-care academic center, Boston, MA. PATIENTS: Total of 112 patients seen in the minimally invasive gynecologic surgery and urogynecology clinics with symptomatic pelvic organ prolapse. INTERVENTIONS: Laparoscopic hysterectomy, sacrocervico- or sacrocolpopexy along with vaginal prolapse and anti-incontinence procedures as indicated from 2013 to 2017 at Brigham & Women's Hospital and Brigham & Women's Faulkner Hospital performed by a minimally invasive gynecologic surgery and urogynecology team. MEASUREMENTS AND MAIN RESULTS: Of the 112 patients, 52 were outpatient and 60 were admitted (median stay in admission group = 1 day; range 1-3). Patient baseline characteristics, American Society of Anesthesiologists' class, and pelvic organ prolapse quantification stage were similar between the outpatient and admitted cohorts. Most patients underwent hysterectomy at the time of the sacropexy (65.4% outpatient vs 73.3% admitted, p = .08). Concomitant apical prolapse repair was more common in the outpatient group (98.1% vs 85%, p = .02). The proportion of outpatient procedures increased from 17% in 2013 to a peak of 70% in 2016. Operating room time was shorter for the outpatient cohort (103.9 minutes vs 115.5 minutes, p = .04), but other perioperative outcomes were similar. There were no intraoperative complications. The numbers of postoperative complications, readmission, and reoperations were low and similar between outpatient and admitted cohorts. No factor was predictive of admission on regression analysis. CONCLUSION: Laparoscopic apical prolapse repair with concomitant vaginal repairs can be performed safely as an outpatient procedure. A unique team approach may foster a shorter, more efficient procedure without compromising short-term outcomes.

Two-dimensional (2D) versus three-dimensional (3D) laparoscopy for vaginal cuff closure by surgeons-in-training: a randomized controlled trial.

BACKGROUND: Objective evidence is lacking as to the benefit of the addition of 3D vision to conventional laparoscopy in Gynecologic surgery. This study aims to compare 3-D visual system to traditional 2-D laparoscopic visualization for the laparoscopic closure of the vaginal cuff during total laparoscopic hysterectomy by surgeons-in-training [defined as senior OBGYN resident or Minimally Invasive Gynecologic Surgery (MIGS) fellow]. METHODS: 51 patients undergoing total laparoscopic hysterectomy at two tertiary care academic hospitals were randomized to two-dimensional or three-dimensional vision system with cuff closure performed by surgeons-in-training. The primary outcome was the time taken for vaginal cuff closure. Secondary outcomes included peri-operative outcomes and assessment of surgeon's perception of ease of cuff closure. RESULTS: 27 (52.9%) cases were allocated to cuff closure with the 2D system and 24 (47.1%) cases to closure with the 3D vision system. Patient baseline characteristics were similar between the vision systems. Mean vaginal cuff closure time was not significantly different between 2D and 3D vision (10.1 min for 2D versus 12 min for 3D, p = 0.31). An additional 24 s was added to cuff closure time with each 1 kg/m2 increase in BMI, after controlling for potential confounders (p = 0.003). There was no difference in the surgeon rating of ease of cuff closure between 2D and 3D. Peri-operative outcomes are similar among the two groups. CONCLUSION: We did not demonstrate any benefits of 3D vision system over conventional 2D for the task of laparoscopic vaginal cuff suturing performed by surgeons-in-training. RCT Registration Number NCT02192606 https://clinicaltrials.gov/ct2/show/NCT02192606 (July 17, 2014).

Laparoscopic treatment of endometriosis and predictors of major complications: A retrospective cohort study.

INTRODUCTION: Patients with advanced endometriosis may be at an increased risk of surgical complications following laparoscopic treatment of endometriosis; however, this relationship has not been examined. We sought to identify predictors of major complications following laparoscopic treatment of endometriosis. MATERIAL AND METHODS: A retrospective cohort study of women who underwent laparoscopic treatment of suspected endometriosis between 2009 and 2016 within the Division of Minimally Invasive Gynecologic Surgery at Brigham and Women's Hospital, Boston, MA, USA. Predictors of major perioperative complications were assessed by comparing the characteristics of women who had any major intraoperative or postoperative complication with those of women who had no complication. RESULTS: A total of 397 women underwent laparoscopic treatment of suspected endometriosis including excision of superficial endometriosis (55.4%), excision of deep-infiltrating endometriosis (24.9%), fulguration of endometriosis (38.3%), hysterectomy (23.2%), ovarian cystectomy (35.5%), salpingectomy (18.6%), oophorectomy (15.1%), and bowel resection (1.0%). Women were followed for 60 days following surgery, over which time 18 women (4.5%) had a major perioperative complication. Patient characteristics and preoperative imaging were similar between women with and without complications. Women with advanced endometriosis, including stage III or IV endometriosis, deep-infiltrating endometriosis, or rectovaginal disease, were more likely to have a complication, though this did not reach statistical significance (77.8% of women with a complication versus 56.7% of women without a complication had advanced endometriosis, P = 0.077). Women who had a complication were more likely to have undergone adhesiolysis or ureterolysis (88.9% of women with a complication versus 52.5% without a complication underwent adhesiolysis, P = 0.002; and 61.1% of women with a complication versus 28.8% without a complication underwent ureterolysis, P = 0.003). The total number of procedures was greater for women who had a complication (4.3 ± 1.2 vs 3.2 ± 1.5, P = 0.003). All other procedure characteristics were similar between women with and without complications. CONCLUSIONS: Complications following laparoscopic treatment of suspected endometriosis could not be predicted by preoperative patient characteristics or surgical findings of advanced endometriosis. Adhesiolysis, ureterolysis, and an increased number of total procedures may be predictive of perioperative complications, suggesting that surgical complexity as measured by the procedures performed, rather than the disease severity, may increase the risk of a complication compared with women who do not undergo these procedures.

Perioperative Antibiotic Use and Associated Infectious Outcomes at the Time of Myomectomy.

OBJECTIVE: To report the frequency of perioperative antibiotic use at time of myomectomy and associated risk of infectious outcomes. METHODS: We conducted a retrospective cohort study including all women who underwent any route of myomectomy from 2009 to 2016 at two academic hospitals in Boston, Massachusetts. Cases involving chromopertubation or conversion to hysterectomy were excluded from further analysis. Medical records were queried for the use or nonuse of perioperative antibiotics, as well as baseline patient factors and perioperative outcomes. Statistical analyses included univariate comparisons between treatment groups, as well as multivariable logistic regression analyses of infectious morbidity controlling for patient age, route of surgery, presence of high-risk factors, any intraoperative complication, myoma weight, and entrance into the endometrial cavity. Matched cohort analysis also was performed to confirm findings in the setting of underlying differences between groups. RESULTS: A total of 1,211 patients were included in the myomectomy cohort, 92.7% of whom received perioperative antibiotics at the time of surgery. Demographic characteristics were similar between the group that received and the group that did not receive antibiotics. The cases with antibiotic use were associated with longer operative times, higher estimated blood loss, and greater myoma burden. No difference was noted with regard to intraoperative or postoperative complications. Surgical site infection occurred more commonly in the group that did not receive antibiotics (2.9% vs 6.8% in the antibiotic and no-antibiotic groups, respectively; effect size 0.43, 95% CI 0.18-0.97 P=.04), representing a nearly fourfold increase in odds of any surgical site infection in the absence of perioperative antibiotic use (adjusted odds ratio 3.77, 95% CI 1.30-10.97, P=.015). CONCLUSION: A high frequency of antibiotic use was noted at time of myomectomy, despite lack of clear evidence supporting the practice. Patients who received perioperative antibiotics had fewer postoperative infectious outcomes and, in particular, experienced a lower incidence of surgical site infection.

Persistence of Symptoms After Total vs Supracervical Hysterectomy in Women with Histopathological Diagnosis of Adenomyosis.

STUDY OBJECTIVE: To compare symptom persistence in women with adenomyosis based on retention or removal of the cervix at the time of hysterectomy. DESIGN: Retrospective cohort study and follow-up survey (Canadian Task Force classification xx). SETTING: Tertiary care academic hospital in Boston, Massachusetts. PATIENTS: Women (n = 1580) who underwent laparoscopic hysterectomy for benign indications between 2008 and 2012 at Brigham and Women's Faulkner Hospital and Brigham and Women's Hospital. INTERVENTION: Retrospective chart review and follow-up survey. MEASUREMENTS AND MAIN RESULTS: Among the 1580 women contacted, 762 (48%) responded to the postoperative symptom resolution survey. Of these 762 women, 623 agreed to participate in the study. Menopausal women or those who had undergone bilateral salpingo-oophorectomy were excluded. Adenomyosis was identified on histopathologic evaluation of the uterus in 171 of the remaining 443 women (39%). Compared with women without adenomyosis, those with adenomyosis were older on average (mean age, 46.6 ± 6.8 years vs 45.0 ± 5.5 years; p = .009) and more likely to report that abnormal bleeding and pain led to their hysterectomy (87.7% vs 79.8%; p = .03 and 64.9% vs 51.4%; p = .009, respectively). The rates of total and supracervical hysterectomies were similar in the 2 groups. Following surgery, women with adenomyosis were less likely than those without adenomyosis to report persistent pain (adjusted odds ratio [aOR], 0.43; 95% confidence interval [CI], 0.20-0.93; p = .03). Persistent bleeding was similar in the 2 groups (aOR, 0.97; 95% CI, 0.49-1.93; p = .94). Among women with adenomyosis, multivariable logistic regression showed no difference in persistence of symptoms with cervical removal or retention at the time of hysterectomy. CONCLUSION: Compared with women without adenomyosis, those with histopathologically proven adenomyosis were less likely to report persistent pain following hysterectomy. Retention of the cervix does not appear to increase the risk of symptom persistence or postprocedure patient satisfaction.

Prospective Evaluation of Manual Morcellation Techniques: Minilaparotomy versus Vaginal Approach.

STUDY OBJECTIVE: To compare the number of days required to return to daily activities after laparoscopic hysterectomy with 2 tissue extraction methods: manual morcellation via colpotomy or minilaparotomy. Secondary outcomes were additional measures of patient recovery, perioperative outcomes, containment bag integrity, and tissue spillage. DESIGN: Multicenter prospective cohort study and follow-up survey (Canadian Task Force classification II-2). SETTING: Two tertiary care academic centers in northeastern United States. PATIENTS: Seventy women undergoing laparoscopic hysterectomy with anticipated need for manual morcellation. INTERVENTIONS: Tissue extraction by either contained minilaparotomy or contained vaginal extraction method, along with patient-completed recovery diary. MEASUREMENTS AND MAIN RESULTS: Recovery diaries were returned by 85.3% of participants. There were no significant differences found in terms of average pain at 1, 2, or 3 weeks after surgery or in time to return to normal activities. Patients in both groups used narcotic pain medication for an average of 3 days. After adjusting for patient body mass index, history of prior surgery, uterine weight, and surgeon, there were no differences found for blood loss, operative time, length of stay, or incidence of any intra- or postoperative complication between groups. All patients had benign findings on final pathology. More cases in the vaginal contained extraction group were noted to have bag leakage on postprocedure testing (13 [40.6%] vs 3 [8.3%] tears in vaginal and minilaparotomy groups, respectively; p = .003). CONCLUSION: Regarding route of tissue extraction, contained minilaparotomy and contained vaginal extraction methods are associated with similar patient outcomes and recovery characteristics.

Incisional Outcomes of Umbilical vs Suprapubic Mini-laparotomy for Tissue Extraction: A Retrospective Cohort Study.

STUDY OBJECTIVE: To compare outcomes following umbilical minilaparotomy and suprapubic minilaparotomy for tissue extraction. DESIGN CLASSIFICATION: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Two large academic medical centers. PATIENTS: Women who underwent a minilaparotomy for tissue extraction following a laparoscopic hysterectomy or myomectomy between 2014 and 2016. INTERVENTIONS: Umbilical or suprapubic minilaparotomy for tissue extraction. MEASUREMENTS AND MAIN RESULTS: A total of 374 women underwent laparoscopic hysterectomy or myomectomy with minilaparotomy, including 289 (77.3%) with an umbilical minilaparotomy and 85 (22.7%) with a suprapubic minilaparotomy. The 2 groups were similar in terms of age, body mass index, parity, surgical history, procedure type, surgical approach, and surgical indication. The size of the minilaparotomy incision and the specimen weight were significantly smaller in the umbilical minilaparotomy group (mean, 3.3 ± 0.8 cm vs 4.2 ± 0.6 cm [p < .001] and 472.6 ± 357.1 g vs 683.0 ± 475.7 g [p < .001], respectively). Two women in the suprapubic minilaparotomy group sustained a bladder injury during creation of the incision. There were no other complications related to the minilaparotomy in either group. Postoperative outcomes related to the minilaparotomy incision were compiled using the medical record and a follow-up survey. Of the 374 women in this cohort, 163 responded to a detailed survey about their minilaparotomy incision (response rate, 43.5%). With regard to the minilaparotomy, 52.7% of women reported incisional symptoms; 25.9% had increased pain at the incision, 8.3% had an incisional infection, and 2.7% reported an incisional hernia. There was no significant between-group difference in incisional outcomes; however nearly 3 times as many women in the umbilical minilaparotomy group reported concerns about incisional hernia (3.1% vs 1.2%; p = .833). These findings were maintained in a multivariable logistic regression analysis. No patient or procedure characteristics were significantly associated with the development of hernia. CONCLUSION: There were no significant difference in incisional symptoms, pain, or infection following umbilical minilaparotomy vs a suprapubic minilaparotomy for tissue extraction. Although not statistically significant, the rate of incisional hernia was higher at the umbilical site compared with the suprapubic site.

Essure Removal for the Treatment of Device-Attributed Symptoms: An Expanded Case Series and Follow-up Survey.

STUDY OBJECTIVE: To evaluate perioperative outcomes and symptom resolution in women undergoing removal of the Essure device for device-attributed symptoms. DESIGN: Retrospective case series and follow-up patient survey (Canadian Task Force classification III). SETTING: Large academic medical center. PATIENTS: Fifty-two women who underwent laparoscopic or hysteroscopic Essure removal between 2012 and 2016. INTERVENTIONS: Women underwent one of four procedures: laparoscopic hysterectomy (LH) and bilateral salpingectomy (BS), laparoscopic BS and cornuectomy, laparoscopic Essure removal and BS, or hysteroscopic Essure removal and laparoscopic BS. MEASUREMENTS AND MAIN RESULTS: Fifty-two women who underwent Essure removal were asked to complete a survey regarding symptom resolution and quality of life following the procedure. Thirty-two women (61.5%) responded to the survey. Seventy-five percent (24/32) reported almost total or total improvement in quality of life, 56.3% (18/32) for sex life, 53.1% (17/32) for pelvic pain, and 65.6% (21/32) for daily activities. The majority of women reported some degree of improvement in all four domains queried (87.5%, 28/32). When asked about their symptoms in general, 31.3% (10/32) of women reported ongoing or worse symptoms after Essure removal. All procedures took approximately one hour (mean 65 min, SD 33 min), were associated with minimal blood loss (mean 31 mL, SD 17), and had no perioperative complications. CONCLUSION: Essure removal is a procedure that may be effective for treating most women with symptoms attributed to the device. Patients should be counseled that some symptoms may persist or even worsen following surgery.

Outpatient Hysterectomy Volume in the United States.

OBJECTIVE: To estimate the number of outpatient hysterectomies being performed annually in the United States in an effort to offer more correct estimates of hysterectomy use in light of reported decreasing inpatient case volume. METHODS: This is a cross-sectional analysis of State Ambulatory Surgery and Services Databases from 16 states with complete information for year 2011. Adult women undergoing hysterectomy were included. Procedure volume, route, and associated patient and surgical characteristics were calculated. RESULTS: There were 64,612 ambulatory hysterectomies reported; 81.5% of surgeries were performed laparoscopically and 16% vaginally. If these numbers are extrapolated to national estimates, this represents 100,000-200,000 outpatient hysterectomies per year. The strongest driver of the laparoscopic, compared with vaginal, route of hysterectomy in this data set was presence of cancer (odds ratio 4.01 [3.19-5.05], P<.001). In addition to indication for surgery, patient characteristics such as age, race, income, location, and primary payer were associated with mode of hysterectomy. The laparoscopic surgeries were associated with shorter length of stay (mean stay 0.65 days, [99% confidence interval 0.65-0.66] compared with 0.79 days [0.78-0.81], adjusted incidence rate ratio 0.89 [0.86-0.92], P<.001) and higher mean charges ($24,227 [$24,053-24,402] versus $14,068 [$13,811-14,330], P<.001) compared with vaginal surgeries. CONCLUSION: The perceived decline that has been reported in national hysterectomy volume may represent lack of reporting of surgeries performed in ambulatory settings. This information has considerable implications for business, public health interventions, and insurance carriers among other key stakeholders in women's health care delivery.

Case Report: Three-Dimensional Printed Model for Deep Infiltrating Endometriosis.

The combination of a thorough physical examination and imaging with either magnetic resonance imaging (MRI) or pelvic ultrasound are important in the preoperative planning for deep infiltrating endometriosis (DIE). A 2-dimensional (2D) rendering of the pathology by imaging does not always accurately represent intraoperative findings. The detailed topographical relationship and extent of surrounding tissue invasion can be better appreciated by 3-dimensional (3D) modeling. A 49-year-old patient with history of endometriosis and persistent pain underwent preoperative MRI that showed features consistent with DIE endometriosis. Surgery was performed, and the findings were documented. A 3D printed model of the DIE was generated from the MRI and retrospectively compared with intraoperative findings. The 3D model demonstrated both the laterality and spatial relationship of the endometriotic nodule to the posterior uterine wall and rectum. Three-dimensional printing of DIE may be a beneficial adjunct to 2D imaging and can identify further structural relationships to support surgical planning.

Comparison of Morcellation Techniques at the Time of Laparoscopic Hysterectomy and Myomectomy.

STUDY OBJECTIVE: To compare perioperative outcomes associated with the use of 3 techniques for tissue removal at the time of laparoscopic hysterectomy and myomectomy. DESIGN: A retrospective cohort study (Canadian Task Force classification II-2). SETTING: An academic hospital in Boston, MA. PATIENTS: Women who underwent a laparoscopic or robot-assisted laparoscopic hysterectomy or myomectomy involving tissue morcellation in 2014. INTERVENTIONS: One of 3 morcellation techniques: electronic power morcellation (PM), manual vaginal morcellation via the vagina (VM), or manual morcellation via minilaparotomy (ML). MEASUREMENTS AND MAIN RESULTS: Of the 297 cases included in this study (137 myomectomies, 62 total laparoscopic hysterectomies, and 98 laparoscopic supracervical hysterectomies), 96% of the cases were performed by fellowship-trained surgeons using conventional laparoscopy. Containment bags were used at the time of tissue extraction in 77% of the cases. Baseline characteristics and perioperative outcomes were similar in all groups. In hysterectomy cases, the average specimen size was largest in the ML group (591 ± 419 g in the ML group compared with 368 ± 293 g in the PM group and 449 ± 175 g in the VM group, p = .0009). After multivariate regression, no significant difference was found in blood loss, length of stay, or complications. The operative time was shorter in the PM group compared with the ML group by 16 minutes (mean = 140 minutes [95% confidence interval, 130-149 minutes] compared with 156 [95% confidence interval, 146-167], p = .02); this association remained significant once additionally adjusting for the use or nonuse of containment bags (p = .05). CONCLUSION: We did not detect a significant difference between the 3 morcellation techniques when comparing the perioperative complications although the longest operative times were noted for the minilaparotomy approach. All 3 morcellation techniques represent viable options for tissue extraction at the time of minimally invasive surgery.

Management of Endometriosis Involving the Urinary Tract.

Endometriosis is a common cause of infertility and disabling pelvic pain in reproductive age women. The most widely accepted theory of its pathogenesis is the retrograde flow of menstrual products, although extra-abdominal and extrapelvic diagnoses have been made. After the pelvic peritoneum and gynecologic structures, the most commonly affected sites are the lower gastrointestinal and urinary tracts. When the urinary tract is involved, the bladder is the predominant site, followed by the ureters. The focus of this seminar will thus be these two anatomic sites. Delayed diagnosis is unfortunately common for endometriosis as a whole, but more so when extrapelvic sites are involved. While the first-line therapy for endometriosis is medical management, urinary tract involvement often represents advanced stage of the disease, thereby requiring surgical intervention. With timely diagnosis and intervention by skilled gynecologic or urologic surgeons, favorable outcomes can be attained.

The Use of CystoSure to Enable Posthysterectomy Cystoscopic Evaluation: A Case Series.

Cystoscopy can be used to diagnose urologic injuries at the time of gynecologic surgery. Current cystoscopy setup involves removing the indwelling catheter placed for the procedure and assembling a multicomponent cystoscope. The objective of this study was to evaluate and report on our initial experience with CystoSure (Emmy Medical, Holliston, MA), a new Food and Drug Administration-approved device designed to facilitate perioperative diagnostic cystoscopy. The CystoSure catheter is an 18F quad-port silicone transurethral catheter with a central sealed port for the cystoscope and a side port that allows for bladder filling. A retrospective chart review was performed of women who underwent benign laparoscopic or robotic gynecologic surgery with cystoscopy at Brigham and Women's Faulkner Hospital, Boston, MA, from May 1, 2015, to August 31, 2015. Thirty women underwent cystoscopy during the study period. The CystoSure catheter is placed at the beginning of the procedure. Total laparoscopic hysterectomy was the most common procedure, representing 90% of cases (27/30). Using the CystoSure system, full bladder survey and bilateral ureteral jets were easily evaluated in 87% (26/30) of the patients. Of the 26 cystoscopies performed successfully, 1 intravesical suture was diagnosed and addressed. In the remaining 4 patients, the 18F CystoSure catheter was too large for the urethral orifice, and a 16F catheter was used for the case. The CystoSure device allows for minimal setup and efficient performance of diagnostic cystoscopy postgynecologic surgery.

Nonresectoscopic endometrial ablation in high-risk surgical patients: a cohort study.

STUDY OBJECTIVE: To evaluate the use of nonresectoscopic endometrial ablation in women with high anesthetic and surgical risk compared with low-risk women based on the American Society of Anesthesia (ASA) physical status stratification. DESIGN: This is a cohort study of women who were classified as high-risk (HR) or low-risk (LR) cohorts based on ASA physical status stratification. The ASA classification includes 6 grades: ASAP1, a normal healthy person; ASAP2, mild systemic disease; ASAP3, severe systemic disease; ASAP4, severe systemic disease that is a constant threat to life; ASAP5, a critically ill patient who is not expected to survive without the operation; and ASAP6, declared brain-dead patient whose organs are being removed for donor purposes. Baseline characteristics including comorbidities were obtained. Outcome measures included amenorrhea, treatment failure, and operative complications. The time to treatment failure was compared using Kaplan-Meier analysis. Risk adjustments were performed using regression models. SETTING: Academic medical center in the Upper Midwest. PATIENTS: Seven-hundred eleven women underwent nonresectoscopic endometrial ablation at our institution between January 1998 and December 2005. INTERVENTIONS: Bipolar radiofrequency was used in 448 women and thermal balloon ablation in 263 women. MEASUREMENTS AND MAIN RESULTS: The HR cohort had a higher proportion of women with cardiac disease (27.1% vs. 6.7%, p < .001) and more women with nongynecologic cancer (12.3% vs. 2.9%, Fisher exact test, p < .001). Nonetheless, endometrial ablation had comparable efficacy in both the HR and LR cohorts with 5-year failure rates of 11.7% and 14.8% (p = .659), respectively. Amenorrhea rates were also similar in both cohorts (29.7% vs. 27.2%, p = .645). After adjusting for known confounders including age, parity, dysmenorrhea, previous tubal ligation, uterine length, and the type of the procedure, the calculated hazard ratio for failure in the HR cohort was 0.80 (95% confidence interval; 0.31-1.74, p = .607), and the adjusted odds ratio for amenorrhea was 1.27 (95% confidence interval, 0.71-2.20; p = .411). Complications were rare in both groups. The mortality rate in the HR cohort was significantly higher compared with the LR cohort (7.9% vs. <1%, p < .001), but this was not related to the ablation procedures. CONCLUSION: For women who are high anesthetic and surgical risks because of serious underlying comorbidities, nonresectoscopic endometrial ablation can provide minimally invasive, safe, and effective therapy for menorrhagia.
