Barriers to Referral to Fellowship-trained Minimally Invasive Gynecologic Surgery Subspecialists.

STUDY OBJECTIVE: To determine patterns and barriers for referral to fellowship-trained minimally invasive gynecologic surgeons. DESIGN: Questionnaire. SETTING: United States and its territories and Canada. PARTICIPANTS: Actively practicing general obstetrician/gynecologists (OB/GYNs). INTERVENTIONS: Internet-based survey. MEASUREMENTS AND MAIN RESULTS: Of 157 respondents, 144 (91.7%) general OB/GYNs were included. Subspecialty fellowship training resulted in the exclusion of 13 (8.3%) respondents. A total of 86 respondents (59.7%) considered referral to fellowship-trained minimally invasive gynecologic surgery (MIGS) subspecialists. The top 3 cited reasons for nonreferral were adequate residency training (n = 84, 58.3%), preference for continuity of care (n = 48, 33.3%), and preference for referral to other subspecialists (n = 46, 31.9%). The top 3 cited reasons for referral to MIGS subspecialists were complex pathology (n = 92, 63.9%), complex medical and/or surgical history (n = 76, 52.8%), and out of scope of practice (n = 53, 36.8%). If providers required intraoperative assistance, respondents consulted an OB/GYN colleague with comparable training (n = 50, 34.7%), gynecologic oncologist (n = 48, 33.3%), or non-OB/GYN surgical subspecialist (n = 33, 22.9%). Factors that were not associated with the decision to refer to MIGS subspecialists included years in practice (p = .13), additional training experiences beyond residency (p = .45), and number of hysterectomies performed by laparotomy (p = .69). Self-reported high-volume surgeons (p <.01) were less likely to refer. In contrast, providers who self-reported as low-volume surgeons (p = .02) and were aware of MIGS subspecialists in the community (p <.01) were more likely to consider referral. Respondents reported using a laparoscopic approach to hysterectomy most frequently (n = 79, 54.9%). In contrast, 36.8% preferred the laparoscopic route for themselves or their partner, whereas 48.6% preferred the vaginal approach. CONCLUSION: Most of the general OB/GYNs would consider referral to fellowship-trained MIGS subspecialists. Providers who reported adequate residency training and those who preferred continuity of care or referral to other surgical subspecialists were less likely to refer to MIGS subspecialists.

Management and outcomes of primary vaginal Cancer.

OBJECTIVE: To analyze clinical characteristics and survival of patients with primary vaginal cancer. METHODS: Retrospective analysis of patients with primary squamous, adenocarcinoma and adenosquamous cell carcinoma of the vagina identified from the Mayo Clinic Cancer Registry between 1998 and 2018. RESULTS: A total of 124 patients were identified: stage I, 39 patients; stage II, 44, stage III, 20 and stage IV, 21. Patients with stage III and IV were older as compared to stage I and II. (mean ages 61 vs 67) (p = 0.024). Squamous cell carcinoma made up 71% of tumors. History of other malignancy was present in 24% patients. Median follow-up time was 60 months (range 1-240). Five-year PFS in stage I, II, III and IV was 58.7%, 59.4%, 67.3% and 31.8%, respectively (p = 0.039). Five-year DSS was 84.3%, 73.7%, 78.7% and 26.5% respectively (p < 0.001). Advanced stage, tumor size >4 cm, entire vaginal involvement, and lymph node (LN) metastasis were poor prognosticators in univariate analysis. Primary surgery in stage I/II patients had similar survival outcomes as compared to primary radiation, but post-operative RT rate was 55%. Brachytherapy alone was associated with a high local recurrence (80%) in stage I/II patients. The addition of brachytherapy had improved 5-year PFS and DSS than EBRT alone in patients with stage III/IVA. (p < 0.001). CONCLUSION: Surgery or radiation is effective treatment for vaginal cancer stage I and II. The addition of brachytherapy to external pelvic radiation increases survival in stages III-IV.

Tumor-free margins and local recurrence in squamous cell carcinoma of the vulva.

OBJECTIVE: To investigate the relation of pathologic tumor-free margins and local recurrence in patients who underwent primary surgery for vulvar squamous cell carcinoma. METHODS: In this retrospective analysis, patients with stage I-III vulvar squamous cell carcinoma who underwent primary surgery between 2000 and 2018 were identified from the Mayo Clinic Cancer Registry. RESULTS: A total of 335 patients were included and divided into three groups according to tumor-free margins: group 1 (<3 mm, n = 32); group 2 (≥3 to <8 mm, n = 151); group 3 (≥8 mm, n = 152). The median follow-up time was 73 months (range 2-240). A total of 78 (23.3%) patients developed local recurrence. With the inverse propensity score weighing method adjusting baseline characters, margins <8 mm had inferior local control (HR 1.98, 95% CI 1.13-3.41). The 5-year local disease-free survival (DFS) was 48.2%, 81.5% and 84.6% for group 1, 2 and 3 respectively (p < 0.001). There were no differences in groin lymph nodes relapse (p = 0.850), distant metastases (p = 0.253), or disease-specific survival (DSS) (p = 0.289) among the three groups. Margins <8 mm, midline involvement, multifocal disease, precancerous lesions on margins and depth of invasion >1 mm were found to be poor prognosticators for local DFS in univariate analysis. Multifocal disease was the strongest predictor for local recurrence in multivariate analysis (HR 4.32, 95% CI 2.67-6.99). CONCLUSION: Patients undergoing primary surgery for vulvar squamous cell carcinoma with tumor free-margins <8 mm have a higher local recurrence rate.

Comparing survival outcomes between surgical and radiographic lymph node assessment in locally advanced cervical cancer: A propensity score-matched analysis.

OBJECTIVE: To investigate progression-free survival (PFS) and overall survival (OS) between women who underwent surgical versus radiographic assessment of pelvic lymph nodes (PLN) and para-aortic lymph nodes (PALN) prior to chemoradiation therapy for cervical cancer. METHODS: In this retrospective cohort analysis, patients with stage IB2 - IIIB squamous cell, adenocarcinoma and adenosquamous carcinoma of the cervix who completed concurrent chemoradiation therapy (CCRT) between 2000 and 2017 from the Mayo Clinic Cancer Registry were identified. A 1:2 propensity score matching between surgical and imaging groups was performed and PFS and OS were compared between groups. RESULTS: 148 patients were identified and after propensity score matching, 35 from the surgical group and 70 from the imaging group were included in the analysis. There were no statistical differences in baseline characteristics between the 2 groups. The median follow-up time was 41 months (range 7-218) for the surgical group and 51.5 months (range 7-198) for the imaging group. Five-year PFS was 62.6% for the surgical group and 72.4% in imaging group (HR 1.11, 95% CI 0.54-2.30, p = 0.77). Five-year OS was 70.2% for the surgical group and 70.5% for the imaging group (HR 1.02, 95% CI 0.46-2.29, p = 0.96). FIGO stage, PALN metastasis, and parametrial involvement were found to be poor prognosticators for PFS and OS in univariate analysis. Only PALN metastasis significantly predicted unfavorable PFS (HR 2.76, 95% CI 1.23-6.18, p = 0.01) and OS (HR 3.46, 95% CI 1.40-8.55, p = 0.01) in multivariate analysis. There were no differences in locoregional recurrence and distant metastasis between the two groups (p = 0.33 and 0.59 respectively). CONCLUSION: Patients with cervical cancer who underwent radiographic assessment of PLN and PALN had comparable survival outcomes to surgical assessment.

Temporary oophoropexy and uteropexy during gynecologic surgery.

Laparoscopic or robotic procedures involving extensive dissection of the posterior cul-de-sac and pelvic sidewalls often require the surgeon and assistants to manipulate the uterus and adnexa to optimize intraoperative visualization and access pathology. This is especially true during excision of endometriosis surgeries. Temporary oophoropexy and uteropexy improve intraoperative visualization and decrease the necessity for additional ports and surgical assistants. These procedures can be efficiently completed by using a Keith needle and suture passed suprapubically (uteropexy) or through the bilateral lower quadrants (oophoropexy) (Figure), through the target viscera, and back through the abdominal wall. The suture is then secured at the level of the abdominal wall. A video was included to describe and demonstrate these procedures. Temporary oophoropexy and uteropexy free the assistant to provide countertraction, irrigation, and removal of specimens rather than limiting the assistant to the sole duty of retraction. This can in turn improve operating room efficiency and safety.

Cost-effective minimally invasive gynecologic surgery: emphasizing surgical efficiency.

PURPOSE OF REVIEW: The United States has the highest healthcare costs among developed countries. This review evaluates surgical practices and equipment choices during endoscopic hysterectomy, highlighting opportunities for the gynecologic surgeon to reduce costs and maximize surgical efficiency. RECENT FINDINGS: There are opportunities to economize at every step of the endoscopic hysterectomy. When surgeons are provided education about instrumentation costs, the cost of hysterectomy has been shown to decrease. Colpotomy has been found to be the rate-limiting step in laparoscopic hysterectomy; use of a uterine manipulator likely saves time and money. When evaluating the economic impact of route of surgery, the cost differential between laparoscopic and robotic-assisted hysterectomy has decreased. Robotic-assisted hysterectomy may be more cost-effective in some cases, such as for larger uteri. From a systems-level perspective, dedicating a specific operating room team to the gynecology service can decrease operative time. SUMMARY: The gynecologic surgeon is best equipped to control surgery-related costs by making choices that improve surgical efficiency and decrease operating room time. If a costlier piece of equipment leads to a more efficient case, the choice may be more cost-effective. There are multiple systems-level changes that can be implemented to decrease surgery-related costs.

Perioperative Outcomes of Total Vaginal Hysterectomy in Women with Prior Cesarean Delivery.

STUDY OBJECTIVE: To compare the incidence of perioperative complications of total vaginal hysterectomy (TVH) in women with and without a prior cesarean section (CS). DESIGN: Retrospective cohort. SETTING: Tertiary care academic institution. PATIENTS: A total of 742 women who underwent TVH over a 5-year period. INTERVENTIONS: TVH. MEASUREMENTS AND MAIN RESULTS: Prior CS did not increase the overall rate of Clavien-Dindo grades 2 to 3 complications (p =.20). The incidence of cystotomy (2.2% CS vs 1.1% no CS, p =.29), ureteral injury (1.1% vs 0.2%, p =.23), proctotomy (1.1% vs 0.2%, p =.23), postoperative bleeding (1.1% vs 0.6%, p =.47), or reoperation (0.0% vs 0.3%, p = 1.00) was not increased from having a prior CS. Prior CS increased blood transfusion (5.6% vs 0.6%, p <.05) but did not increase conversion to laparotomy (2.2% vs 0.6%, p =.15), length of hospitalization (11.2% vs 14.1% discharge on the same day, 66.3% vs 63.6% discharge on postoperative day 1, and 22.5% vs 22.4% discharge on or after postoperative day 2, p =.76), or 30-day readmission rates (1.1% vs 3.5%, p =.34). CONCLUSION: In patients who underwent TVH, a prior CS increased postoperative blood transfusion but did not increase the risk for overall perioperative complications.

Robotic Excision of Full-thickness Diaphragmatic Endometriosis.

STUDY OBJECTIVE: To describe a robotic approach to excision of full-thickness diaphragmatic endometriosis. DESIGN: Surgical technique demonstration. SETTING: Symptomatic diaphragmatic endometriosis is commonly associated with lesions that are deeply invasive. In the presence of symptomatic diaphragmatic endometriosis, the posterior diaphragm should be explored. INTERVENTIONS: This video presents a systematic robotic approach to the excision of diaphragmatic endometriosis, highlighting key anatomic landmarks and technical considerations to complete the procedure safely and effectively. Resection of hepatic ligaments, use of a 30° endoscope, and right lateral access can be used to visualize this anatomic area [1]. The phrenic nerve is rarely identified during laparoscopy, if at all, and an inability to identify this structure during hemidiaphragm resection does not seem to result in significant patient morbidity. After diaphragm resection, the pleural cavity and lung should be systematically inspected to rule out the presence of additional endometriotic lesions. If the long axis of the diaphragmatic defect is parallel to the posterior chest wall and can be closed tension-free, then mesh is not necessary [1]. Insertion of a red rubber catheter into the thorax along with the use of negative pressure suction at the end of closure of the diaphragmatic defect may avoid use of a postoperative chest tube. CONCLUSION: The use of robotic assistance for resection of diaphragmatic endometriosis makes this procedure easy and safe to perform. Compared with ablative procedures, complete surgical excision offers higher rates of symptom improvement and resolution in patients with diaphragmatic endometriosis.

Predictors of Postoperative Urinary Retention in Outpatient Minimally Invasive Hysterectomy.

STUDY OBJECTIVE: To identify risk factors associated with postoperative urinary retention in patients undergoing outpatient minimally invasive hysterectomy. DESIGN: A retrospective cohort study. SETTING: An academic medical center. PATIENTS: All patients undergoing outpatient minimally invasive hysterectomy between January 2013 and July 2018 were considered for inclusion in the study. INTERVENTIONS: Outpatient laparoscopic, vaginal, or robotically assisted laparoscopic hysterectomy. MEASUREMENTS AND MAIN RESULTS: Four hundred forty-four patients met the inclusion criteria. Postoperative urinary retention occurred in 94 patients, and 347 patients successfully passed their voiding trial in the postanesthesia care unit for a pass rate of 79%. Demographic characteristics were similar, except patients who experienced postoperative urinary retention were less likely to be menopausal (23.4% vs 34.7%, p = .038). Those with urinary retention received more perioperative opioids (morphine milligram equivalent of 14.4 mg vs11.2 mg, p = .012), had longer operative times (122.9 ± 55.6 vs 95.7 ± 42.3 minutes, p < .01), and experienced more blood loss (105.3 ± 134.4 vs 78.5 ± 86.8 mL, p = .025). The rate of urinary tract infections was similar. Logistic regression analysis showed that the route of hysterectomy and age were not associated with an increased risk for urinary retention, whereas a longer operative time and higher doses of perioperative opioid use were. CONCLUSION: In patients undergoing minimally invasive outpatient hysterectomy, a longer operative time and increased perioperative narcotic use increases the risk of postoperative urinary retention.

Shared decision-making in opioid prescribing for minimally invasive hysterectomy: A prospective randomized controlled trial.

OBJECTIVE: To determine the impact of shared decision-making in postsurgical opioid prescribing in women who underwent minimally invasive (MIS) hysterectomy. DESIGN: A randomized controlled trial. SETTING: A single, tertiary care, academic center. PATIENTS AND PARTICIPANTS: From January 2019 through April 2020, 73 women aged 18 years and older who had a planned MIS hysterectomy with the Department of Gynecology were enrolled into the study (36 in the standard arm and 37 in the patient-directed arm). INTERVENTIONS: Participants were assigned either to the standard arm (30 tablets) or patient-directed arm (0-30 tablets) of oxycodone 5 mg. MAIN OUTCOME MEASURES: The primary outcome was the percentage of excess opioid tablets, calculated by the number of unused tablets divided by the number of tablets prescribed. Secondary outcomes included total opioid tablets used, frequency of obtaining additional opioid tablets after discharge, frequency of unscheduled post-operative visits, and patient satisfaction with number of opioid tablets prescribed. RESULTS: Age, race, and body mass index did not differ between groups. Hysterectomies were performed via laparoscopy (16.9 percent), robotic-assisted laparoscopy (38.5 percent), and vaginal routes (44.6 percent). The median (IQR) number of oxycodone prescribed in the patient-directed arm was 15.0 (12.0 and 24.0) tablets. The standard arm had a greater percentage of excess oxycodone tablets 73.6 percent (0.03) than the patient-directed arm 56.3 percent (0.03, p < .01). However, there was no difference in the total number of oxycodone used by patients in the standard (mean 7.9 [0.5] tablets) and patient-directed arms (mean 8.4 [0.5] tablets, p = .50). The mean number of oxycodone used for the entire cohort was 8.1 (0.4) tablets. CONCLUSIONS: Shared decision-making significantly decreased the percent of excess oxycodone tablets but did not decrease the total number of oxycodone tablets used in patients undergoing MIS hysterectomy. Patients used about 22 tablets less than the standard 30 tablets prescribed.

Radical Extirpation With Intraoperative Radiotherapy for Locally Recurrent Gynecologic Cancer: An Institutional Review.

OBJECTIVE: To report survival outcomes in patients with locally recurrent gynecologic cancers managed with curative-intent radical extirpation, perioperative external beam radiotherapy, and intraoperative radiotherapy (IORT). PATIENTS AND METHODS: We conducted a retrospective cohort analysis of 44 patients with locally recurrent gynecologic cancer treated at a single tertiary-care center (Mayo Clinic in Arizona) over a 15-year period (January 1, 2004, to July 31, 2019). This cohort included patients with uterine (n=21, 47.7%), ovarian (n=3, 6.8%), cervical (n=11, 25.0%), vaginal (n=2, 4.5%), vulvar (n=1, 2.3%), and unknown primary (n=6, 13.6%) cancer. Curative-intent radical extirpation included pelvic exenteration (n=13, 29.5%), laterally extended endopelvic resection (n=22, 50.0%), excision of para-aortic lymph node metastasis (n=8, 18.2%), and radical vaginectomy (n=1, 2.3%). Of the 44 patients in our cohort, 37 (84.1%) received IORT and 7 (15.9%) had intended to receive IORT but did not receive it. RESULTS: The median follow-up for the 44 patients was 12 months (range, 1 to 161 months). For patients who received IORT, the median progression-free survival (PFS) and overall survival (OS) were 13 and 21 months, respectively, and the 3-year cumulative incidence of central, locoregional, and distant recurrence was 27.0% (10 of 37), 40.5% (15 of 37), and 37.8% (14 of 37), respectively. Surgical margins were classified as negative (28 of 44, 63.6%), microscopic (11 of 44, 25.0%), or macroscopic (5 of 44, 11.4%). Negative, microscopic, and macroscopic surgical margins resulted in 3-year PFS of 51.8%, 20.5%, and 0%, respectively (P=.01) and 3-year OS of 62.9%, 20.0%, and 0%, respectively (P=.035). Progression-free survival (P=.69) and OS (P=.88) were not different between patients with negative surgical margins who received (n=21) and did not receive (n=7) IORT. Ten of 37 patients (27.0%) had development of grade 3 or higher toxicities, with 1 death due to sepsis. CONCLUSION: Complete tumor resection at the time of curative-intent radical extirpation achieved higher rates of PFS and OS regardless of IORT administration.

Surgical or imaging lymph node assessment in locally advanced cervical cancer: a systematic review and meta-analysis.

OBJECTIVE: To evaluate the survival impact of imaging vs surgical nodal assessment in patients with cervical cancer stage IB2-IVA prior to definitive chemoradiotherapy (CRT). METHODS: PubMed, MEDLINE, Cochrane Library, and ClinicalTrials.gov were used to search for publications in English and Chinese over a 50-year period. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols was used to conduct this review. Inclusion criteria were studies that compared survival outcomes in International Federation of Gynecology and Obstetrics 2009 stage IB2-IVA cervical cancer patients with pre-therapy pelvic and/or aortic lymphadenectomy (LND) or imaging. One or more of the following modalities were used for nodal assessment: computed tomography (CT), magnetic resonance imaging, or positron emission tomography-CT. The National Institutes of Health Quality Assessment Tool was utilized to assess study quality. RESULTS: The initial search identified 65 studies, and five met the inclusion criteria. There were a total of 1,112 patients. Seven hundred and fifty-four underwent pelvic and/or aortic LND and 358 had imaging. When compared to LND, imaging had a sensitivity and specificity of 88.9% and 22.2% for pelvic lymph node (LN), and 33%-62.5% and 92%-95.5% for para-aortic LN. There were no differences in progression-free survival (PFS) (hazard ratio [HR]=1.13; 95% confidence interval [CI]=0.73-1.74; I²=75%; p<0.01) and overall survival (OS) (HR=1.06; 95% CI=0.66-1.69; I²=75%; p<0.01) between surgical and imaging nodal assessment. CONCLUSIONS: Imaging and surgical nodal assessment has comparable PFS and OS in patients with cervical cancer stage IB2-IVA. TRIAL REGISTRATION: PROSPERO Identifier: CRD42020155486.

Short interpregnancy intervals and associated risk of preterm birth in Asians and Pacific Islanders.

PURPOSE: The prevalence of short interpregnancy intervals (IPIs) and associated rates of preterm birth has been understudied in Asian and Pacific Islander populations. We sought to estimate rates of short IPI among Asian subgroups and Pacific Islanders and associated risk of preterm birth. MATERIALS AND METHODS: For this retrospective cohort study, we linked records of women in California with a first birth in 1999-2000 and a second birth before 2005 with hospital discharge data. We used multivariate modeling to determine whether specific Asian ethnicities and Pacific Islanders were at greater risk of short IPI (<6 months, 6-18 months) and if a short IPI increased risk for preterm birth in these groups. RESULTS: Our sample included 189,931 women. In multivariable analyses, Asian subgroups and Pacific Islanders were more likely to have an IPI <6 months than were White women (Pacific Islanders: OR 3.31 (95%CI [2.7, 4.1]); Filipinas: OR 1.51 (95%CI [1.33, 1.71]); Southeast Asians: OR 1.93 (95%CI [1.73, 2.1]); East Asians: OR 1.65 (95%CI [1.48, 1.84]); other Asians: OR 2.04 (95%CI [1.70, 2.4])). CONCLUSIONS: Asian and Pacific Islander women have higher rates of IPI <6 months, but this did not significantly increase their risk of preterm birth.
