RESUMO
OBJECTIVE: To compare long-term risk of reintervention across four uterus-preserving surgical treatments for leiomyomas and to assess effect modification by sociodemographic factors in a prospective cohort study in an integrated health care delivery system. METHODS: We studied a cohort of 10,324 patients aged 18-50 (19.9% Asian, 21.2% Black, 21.3% Hispanic, 32.5% White, 5.2% additional races and ethnicities) who had a first uterus-preserving procedure (abdominal, laparoscopic, or vaginal myomectomy [referred to as myomectomy]; hysteroscopic myomectomy; endometrial ablation; uterine artery embolization) after leiomyoma diagnosis in the 2009-2021 electronic health records of Kaiser Permanente Northern California. We followed up patients until reintervention (second uterus-preserving procedure or hysterectomy) or censoring. We used a Kaplan-Meier estimator to calculate the cumulative incidence of reintervention and Cox regression models to estimate hazard ratios and 95% CIs comparing rates of reintervention across procedures, adjusting for age, parity, race and ethnicity, body mass index (BMI), Neighborhood Deprivation Index, and year. We also assessed effect modification by demographic characteristics. RESULTS: Median follow-up was 3.8 years (interquartile range 1.8-7.4 years). Index procedures were 18.0% (1,857) hysteroscopic myomectomies, 16.2% (1,669) uterine artery embolizations, 21.4% (2,211) endometrial ablations, and 44.4% (4,587) myomectomies. Accounting for censoring, the 7-year reintervention risk was 20.6% for myomectomy, 26.0% for uterine artery embolization, 35.5% for endometrial ablation, and 37.0% for hysteroscopic myomectomy; 63.2% of reinterventions were hysterectomies. Within each procedure type, reintervention rates did not vary by BMI, race and ethnicity, or Neighborhood Deprivation Index. However, rates of reintervention after uterine artery embolization, endometrial ablation, and hysteroscopic myomectomy decreased with age, and reintervention rates for hysteroscopic myomectomy were higher for parous than nulliparous patients. CONCLUSION: Long-term reintervention risks for uterine artery embolization, endometrial ablation, and hysteroscopic myomectomy are greater than for myomectomy, with potential variation by patient age and parity but not BMI, race and ethnicity, or Neighborhood Deprivation Index.

OBJECTIVE: COVID-19 has had an unprecedented impact on medical care use and delivery, including stark reductions in emergency department (ED) volume. The aim of this study was to assess changes in incidence of OB/GYN ED visits and disease severity at time of presentation during the COVID-19 pandemic. STUDY DESIGN: We conducted a multicenter retrospective study of OB/GYN-related ED visits before and during the COVID-19 pandemic. Incidence rates (IRs) and severity measures were compared across time periods and years. RESULTS: A total of 18,668 OB/GYN ED encounters occurred between January 1 and December 31, 2020, compared to 21,014 encounters between January 1 and December 31, 2019. During shelter-in-place, visits decreased by 41% compared to the pre-pandemic period in 2020 before returning to typical rates (incidence rate ratio (IRR) = 0.98 in fall/winter). We found a similar proportion of patients with hemoglobin < 7 g/dL for diagnoses associated with bleeding and patients with white blood cell count > 12,000 per µL in the setting of infection comparing corresponding time periods in 2019 and 2020. There were fewer formal OB/GYN consults, hospital admissions at time of presentation, and urgent surgical procedures performed across all periods in 2020; however, hospitalization within 7 days substantially increased in the first half of 2020. CONCLUSION: The incidence of OB/GYN ED visits declined substantially between March and August 2020 but then returned to pre-pandemic levels by fall/winter 2020. The decreased incidence was not accompanied by an increase in severity of presentation.

BACKGROUND: Although multiple professional organizations encourage minimally invasive surgical approaches whenever feasible, nationally, fewer than half of myomectomies are performed via minimally invasive routes. Black women are less likely than their non-Black counterparts to have minimally invasive surgery. OBJECTIVE: This study aimed to assess the trends in surgical approach among women who underwent minimally invasive myomectomies for uterine leiomyomas within a large integrated healthcare system as initiatives were implemented to encourage minimally invasive surgery, particularly evaluating differences in the proportion of minimally invasive surgery performed in Black vs non-Black women. STUDY DESIGN: We conducted a retrospective cohort study of women, aged ≥18 years, who underwent a myomectomy for a uterine leiomyoma within Kaiser Permanente Northern California between 2009 and 2019. Generalized estimating equations and Cochran-Armitage testing were used to assess myomectomy incidence and linear trend in the proportions of myomectomy by surgical route-abdominal myomectomy and minimally invasive myomectomy. Multivariable logistic regression analyses were used to assess the associations between surgical route and (1) race and ethnicity and (2) complications, controlling for patient demographic, clinical, and surgical characteristics. RESULTS: A total of 4033 adult women underwent a myomectomy during the study period. Myomectomy incidence doubled from 0.12 (95% confidence interval, 0.12-0.13) per 1000 women in 2009 to 0.25 (95% confidence interval, 0.24-0.25) per 1000 women in 2019 (P<.001). During the 11-year study period, the proportion of minimally invasive myomectomy increased from 6.0% to 89.5% (a 15-fold increase). The proportion of minimally invasive myomectomy in Black women remained lower than in non-Black women (54.5% vs 64.7%; P<.001). Black women undergoing myomectomy were younger (36.4±5.6 vs 37.4±5.8 years; P<.001), had a higher mean fibroid weight (436.0±505.0 vs 324.7±346.1 g; P<.001), and had a higher mean body mass index (30.8±7.3 vs 26.6±5.9 kg/m2; P<.001) than their non-Black counterparts. In addition to patient race, surgery performed between 2016 and 2019 compared with surgery performed between 2009 and 2012 and higher surgeon volume compared with low surgeon volume were associated with an increased proportion of minimally invasive myomectomy (adjusted relative risks, 12.58 [95% confidence interval, 9.96-15.90] and 6.63 [95% confidence interval, 5.35-8.21], respectively). Black race and fibroid weight of >500 g each independently conferred lower rates of minimally invasive myomectomy. In addition, there was an interaction between race and fibroid weight such that Black women with a fibroid weight of ≤500 g or >500 g were both less likely to have minimally invasive myomectomy than non-Black women with a fibroid weight of ≤500 g (adjusted relative risks, 0.74 [95% confidence interval, 0.58-0.95] and 0.26 [95% confidence interval, 0.18-0.36], respectively). Operative, perioperative, and medical complications were low during the 11-year study period. In regression analyses, after controlling for race, age, fibroid weight, parity, low-income residence, body mass index, surgeon volume, and year of myomectomy, the risk of complications was not markedly different comparing abdominal myomectomy with minimally invasive myomectomy. Similar results were found comparing laparoscopic minimally invasive myomectomy with robotic-assisted minimally invasive myomectomy except for women who underwent laparoscopic minimally invasive myomectomy had a lower risk of experiencing any medical complications than those who underwent robotic-assisted minimally invasive myomectomy (adjusted relative risk, 0.27; 95% confidence interval, 0.09-0.83; P=.02). CONCLUSION: Within an integrated healthcare delivery system, although initiatives to encourage minimally invasive surgery were associated with a marked increase in the proportion of minimally invasive myomectomy, Black women continued to be less likely to undergo minimally invasive myomectomy than their non-Black counterparts. Race and fibroid weight alone did not explain the disparities in minimally invasive myomectomy.

STUDY OBJECTIVE: To describe trends in minimally invasive hysterectomy (MIH) and assess patient, surgical, and provider characteristics associated with differences in vaginal versus laparoscopic rates within an integrated healthcare system. DESIGN: A retrospective cohort study. SETTING: Kaiser Permanente Northern California from 2008 to 2018. PATIENTS: Patients who underwent MIH for benign conditions excluding uterine prolapse and incontinence surgeries. INTERVENTIONS: Hysterectomies. MEASUREMENTS AND MAIN RESULTS: A total of 27518 hysterectomies were performed for benign indications. Of these, the proportion of MIH increased from 29.1% (2008) to 96.7% (2018) (p <.001). The proportion of vaginal hysterectomies (VHs) of all hysterectomies did not change significantly over the study period (p = .07); however, the proportion of VH among MIH cases decreased from a high of 50.6% in 2008 to 13.2% in 2018 (p <.001). VH rates were lower in obese and morbidly obese patients (p <.001 and p = .02, respectively) and in women with uterine weights >250 g (p <.001). The differences persisted after controlling for patient demographic, clinical, and surgery characteristics. Low surgical volume was inversely associated with VH (adjusted relative risk, 7.19; 95% confidence interval, 6.62-7.81; p <.001). VH rates ranged from 11.5% to 27.8% across service areas (hospitals). Service area remained a significant predictor of VH after controlling for patient (including body mass index and uterine weight) and surgery-related characteristics. Postoperative hospital stay decreased from 33.8 ± 16.4 hours (2008) to 6.1 ± 12.2 (2018) for VH. Operative time was shorter for VH than laparoscopic hysterectomies (LHs) (1.7 vs 2.5 hours; p <.001). Overall operative/perioperative complications were low and not significantly different (VH vs LH). CONCLUSION: As the proportion of MIH increased, LH became the preferred route despite similar rates of postoperative stay and intraoperative complications and shorter operative time for VH compared with LH. Service area and provider volume were independent predictors of MIH route, suggesting that training and evidence-based guidelines for route selection may help preserve VH rates.

STUDY OBJECTIVE: To determine the proportion of patients discharged with a urinary catheter after a same-day benign gynecologic minimally invasive hysterectomy (MIH) according to active vs passive voiding protocols. The secondary objectives included assessing postanesthesia care unit (PACU) duration and postoperative urinary retention (POUR) rate ≤2 weeks of discharge. DESIGN: Retrospective, observational cohort study. SETTING: Large integrated healthcare system serving approximately 40% of the Northern California population. PATIENTS: Patients aged 18 years or older undergoing same-day MIH without urogynecology procedures from 2015 to 2018 were categorized into active or passive voiding trial groups. Active voiding trials were defined as patients arriving in the PACU with a catheter, retrograde filling of the bladder with 300 mL saline then allowing for voiding ≥50% within 30 minutes. If the patients were unable to void this volume, they were discharged with a catheter to be removed within 24 hours. A passive voiding trial involved filling or not filling the bladder before PACU arrival without a catheter, then allowing for voiding or performing a straight catheterization if the patients were unable to void. INTERVENTIONS: Retrospective cohort study. MEASUREMENTS AND MAIN RESULTS: A total of 1644 (83.2%) patients underwent passive voiding trials, and 333 (16.8%) underwent active voiding trials. The proportion of patients discharged with a catheter was lower in the passive voiding group than in the active voiding group (5.4% vs 10.5%; p = .001). The passive group had a shorter mean PACU time than the active group (218 ± 86 vs 240 ± 93 minutes; p <.001). The crude POUR rates for the passive and active voiding groups were 1.8% and 3.0%, respectively (p = .16). CONCLUSION: Within an integrated healthcare system, patients who underwent passive voiding trials compared with those who underwent active voiding trials were discharged home from the PACU after a shorter duration. In addition, a larger proportion of the patients who underwent passive voiding trials were discharged home without a urinary catheter. There were no differences in the POUR rates. Our findings suggest that passive voiding trials can be safely used after a benign MIH to reduce hospital duration, optimize healthcare resources, and improve patient experience.

STUDY OBJECTIVE: To develop a risk prediction model for occult uterine sarcoma using preoperative clinical characteristics in women undergoing hysterectomy for presumed uterine leiomyomata. DESIGN: Cases of uterine sarcoma were identified from the electronic medical records. Age/race-matched controls were selected at a 2:1 ratio (controls:cases) from a cohort of 45 188 women who underwent hysterectomy for uterine leiomyomata or abnormal bleeding during the same time interval. Unadjusted conditional logistic regression was performed to identify risk factors for occult uterine sarcomas, defined as no preoperative suspicion for malignancy. A risk prediction model was developed using a weighted logistic regression model, and the performance of the model was assessed using the receiver operator characteristic curve and corresponding area under the curve. SETTING: A large integrated health care system in California PATIENTS: Women 18 years of age and older who underwent a hysterectomy and were diagnosed with a uterine sarcoma and matched controls from 2006 to 2013. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: There were 117 cases of occult uterine sarcomas that met inclusion criteria during the study period. The final risk prediction model included age, race/ethnicity, number of myomas, uterine weight, uterine size increase, degree of pelvic pain, and recent history of blood transfusion. The risk prediction model showed high accuracy based on the receiver operating characteristic curve method (area under the curveâ¯=â¯0.83; 95% confidence interval, 0.77-0.90); however, the positive predictive values were low (0.048 or less) at all risk thresholds. CONCLUSION: Multiple clinical features are associated with the presence of a uterine sarcoma, but when incorporated into a prediction model, they fail to provide significantly more information about women who may have an unrecognized sarcoma and only marginally improve the certainty about women who are not likely to have sarcoma.

OBJECTIVES: We characterized referral trends over time at a transgender clinic within an integrated health system in Northern California. We identified the transition-related requests of pediatric transgender and gender-nonconforming patients and evaluated differences in referrals by age group. METHODS: Medical records were analyzed for all patients <18 years of age in the Kaiser Permanente Northern California health system who were referred to a specialty transgender clinic between February 2015 and June 2018. Trends in treatment demand, demographic data, service requests, and surgical history were abstracted from medical charts and analyzed by using descriptive statistics. RESULTS: We identified 417 unique transgender and gender-nonconforming pediatric patients. The median age at time of referral was 15 years (range 3-17). Most (62%) identified on the masculine spectrum. Of the 203 patients with available ethnicity data, 68% were non-Hispanic. During the study period, the clinic received a total of 506 referrals with a significant increase over time (P < .001). Most referrals were for requests to start cross-sex hormones and/or blockers (34%), gender-affirming surgery (32%), and mental health (27%). Transition-related requests varied by age group: younger patients sought more mental health services, and older patients sought hormonal and surgical services. Eighty-nine patients underwent gender-affirming surgeries, mostly before age 18 and most frequently mastectomies (77%). CONCLUSIONS: The increase in referrals supports the need for expanded and accessible health care services for this population. The transition-related care of patients in this large sample varied by age group, underscoring the need for an individualized approach to gender-affirming care.

STUDY OBJECTIVE: To investigate rates of utilization of alternative treatments before hysterectomy for benign gynecologic indications within a large integrated health care system. DESIGN: Retrospective cohort study of patients who underwent hysterectomies for benign gynecologic conditions between 2012 and 2014 (Canadian Task Force classification II-2). SETTING: Kaiser Permanente Northern California, a community-based integrated health system. PATIENTS: Women who underwent hysterectomy for a benign gynecologic condition between 2012 and 2014. INTERVENTIONS: From an eligible cohort of 6892 patients who underwent hysterectomy, a stratified random sample of 1050 patients were selected for chart review. Stratification was based on the proportion of indications for hysterectomy. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the use of alternative treatments before hysterectomy. Alternative treatments included oral hormone treatment, leuprolide, medroxyprogesterone intramuscular injections, a levonorgestrel intrauterine device, hormonal subdermal implants, endometrial ablation, uterine artery embolization, hysteroscopy, and myomectomy. Of the 1050 charts reviewed, 979 (93.2%) met the criteria for inclusion in this study. The predominant indication for hysterectomy was symptomatic myomas (54.4%), followed by abnormal uterine bleeding (29.0%), endometriosis (5.8%), pelvic pain (3.1%), dysmenorrhea (3.4%), and other (4.3%). The major routes of hysterectomy were laparoscopy (68.7%) and vaginal hysterectomy (13.4%). Before hysterectomy, 81.2% of patients tried at least 1 type of alternative treatment (33.8% with 1 treatment and 47.4% with at least 2 treatments), and 99.3% of patients were counseled regarding alternative treatments. Compared with younger women age <40 years, women age 45 to 49 years were less likely to use alternative treatments before hysterectomy (adjusted odds ratio, 0.41; 95% confidence interval, 0.21-0.76). There were no variations in treatment rates by socioeconomic status or between major racial and ethnic groups. The final pathological analysis identified myomas as the most common pathology (nâ¯=â¯637; 65.1%); 96 patients (9.8%) had normal uterine pathology. CONCLUSION: More than 80% of patients received alternative treatments before undergoing hysterectomy for a benign gynecologic condition. Additional investigation is warranted to assess alternative treatment use as it relates to preventing unnecessary hysterectomies.

Background: Gender affirming surgeries are increasingly accessible to transgender and non-binary individuals due to changes in health care coverage policies and rising numbers of trained providers. Improved access to care has led to an increase in the number of individuals pursuing gender affirming surgeries. Little is known about how to optimally prepare patients for these surgeries. Aims: This evaluation examined attendees' assessment of a four-hour single-session class developed to prepare transgender and non-binary patients and their caregivers for gender affirming surgeries in a multi-disciplinary transgender clinic within an integrated health care system. Methods: A multi-disciplinary group of providers within a health maintenance organization in Northern California designed and facilitated two separate curricula, one for patients preparing for metoidioplasty/phalloplasty and the other preparing for vaginoplasty. Between November 2015 and June 2017, 214 patients and caregivers took one of the two versions of the class and completed the post-class survey evaluating perceived favorability of the class and preparedness regarding surgery options, complications and postoperative care. Descriptive statistics were used to summarize the Likert scale questions, with 1 showing the least improvement and 5 showing the most. Results: Of the 214 patients and caregivers that completed the survey, the majority reported that they were better informed about their surgical options (mean: 4.4, SD: 0.7), more prepared for surgery (mean: 4.5, SD: 0.6), better informed about possible complications (mean: 4.5, SD: 0.7), and better understood their postoperative care needs (mean: 4.6, SD: 0.6). Of the respondents, 204 (95%) reported they would recommend the course to a friend preparing for gender affirming surgery. Discussion: Our findings demonstrate that a single-session class is a favorable method for preparing transgender and non-binary patients to make informed decisions regarding the perioperative gender affirming surgical process, from preoperative preparedness, to surgical complications, and postoperative care.
RESUMO
OBJECTIVE: To examine trends in minimally invasive hysterectomy and power morcellation use over time and associated clinical characteristics. METHODS: We conducted a trend analysis and retrospective cohort study of all women 18 years of age and older undergoing hysterectomy for benign conditions at Kaiser Permanente Northern California collected from electronic health records. Generalized estimating equations and Cochran-Armitage testing were used to assess the primary outcomes, hysterectomy incidence, and proportion of hysterectomies by surgical route and power morcellation. Logistic regression analysis was used to assess secondary outcomes, clinical characteristics, and complications associated with surgical route. RESULTS: There were 31,971 hysterectomies from 2008 to 2015; the incidence decreased slightly from 2.86 (95% confidence interval [CI] 2.85-2.87) to 2.60 (95% CI 2.59-2.61) per 1,000 women (P<.001). Minimally invasive hysterectomies increased from 39.8% to 93.1%, almost replacing abdominal hysterectomies entirely (P<.001). Vaginal hysterectomies decreased slightly from 26.6% to 23.4% (P<.001). The proportion of nonrobotic laparoscopic hysterectomies with power morcellation increased steadily from 3.7% in 2008 to a peak of 11.4% in 2013 and decreased to 0.02% in 2015 (P<.001). Robot-assisted laparoscopic hysterectomies remained a small proportion of all hysterectomies comprising 7.8% of hysterectomies in 2015. Women with large uteri (greater than 1,000 g) were more likely to receive abdominal hysterectomies than minimally invasive hysterectomy (adjusted relative risk 11.62, 95% CI 9.89-13.66) and laparoscopic hysterectomy with power morcellation than without power morcellation (adjusted relative risk 5.74, 95% CI 4.12-8.00). Laparoscopic supracervical hysterectomy was strongly associated with power morcellation use (adjusted relative risk 43.89, 95% CI 37.55-51.31). CONCLUSION: A high minimally invasive hysterectomy rate is primarily associated with uterine size and can be maintained without power morcellation.

STUDY OBJECTIVE: After the US Food and Drug Administration statement warning against electronic morcellation devices, gynecologic surgeons are performing laparoscopic and robotic myomectomies with minilaparotomy incisions for tissue morcellation and removal. No data exist that focus on the superficial wound complications as a result of these larger incisions. The objective of this study is to compare the rate of wound complications for myomectomy via minilaparotomy versus laparoscopic or robotic myomectomy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Kaiser Permanente Northern California, a large integrated healthcare delivery system. PATIENTS: Women > 18 years of age who underwent a myomectomy from either complete laparoscopic or robotic approach (LR) were compared with minilaparotomy myomectomy (MM), comprising complete minilaparotomy (ML) and laparoscopic or robotic assisted by a minilaparotomy for morcellation purposes only (LRM) from January 2011 through December 2014. INTERVENTION: Myomectomy via LR, complete ML, and LRM. MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed for outcomes of interest, including superficial wound complications and surgical and demographic data. After exclusion criteria were met, 405 cases were included in the study; 270 cases were classified as MM, which included ML (n = 224), or LRM (n = 46). One hundred thirty-five cases were classified as LR. Parametric and nonparametric analyses were used to compare the 2 groups. There was no significant difference between the groups insofar as patient morbidity, including the primary outcome of wound complications and other postoperative complications; emergency visits; or readmissions. There were 2 (1.5%) wound complications in the LR group and 7 (2.6%) in the MM group (p = .72). Similarly, there were no significant differences in the subcategories of wound complications, including cellulitis, seroma, hematoma, skin separation, wound infection, or postprocedure wound complication. The distribution of estimated blood loss was significantly different between LR and MM groups with an interquartile range of 50 to 150 mL in the LR group versus 50 to 300 mL in the MM group (p < .01). The MM group experienced a shorter procedure time with a median procedure time of 125 minutes compared with 169.5 minutes in LR surgeries (p < .01). The LR group demonstrated a significantly shorter median length of hospital stay (LR 5.0 hours vs MM 23 hours; p < .01). CONCLUSION: Compared with MM, LR is associated with a shorter length of hospital stay and longer operating time but no reduction in wound complication or other patient morbidity.

OBJECTIVE: To estimate the incidence of occult uterine sarcoma and leiomyosarcoma in hysterectomies for leiomyomas and the risk associated with their morcellation. METHODS: We conducted a population-based cohort study. All uterine sarcomas from 2006-2013 in an integrated health care system were identified. Age- and race-specific incidences of occult uterine sarcoma were calculated. Kaplan-Meier survival analysis was performed. Crude and adjusted risk ratios of recurrence and death associated with morcellation at 1, 2, and 3 years were estimated using Poisson regression with inverse probability weighting. RESULTS: There were 125 hysterectomies with occult uterine sarcomas identified among 34,728 hysterectomies performed for leiomyomas. The incidence of occult uterine sarcoma and leiomyosarcoma was 1 of 278 or 3.60 (95% confidence interval [CI] 2.97-4.23) and 1 of 429 or 2.33 (95% CI 1.83-2.84) per 1,000 hysterectomies. For stage I leiomyosarcoma (n=111), eight (7.2%) were power and 27 (24.3%) nonpower-morcellated. The unadjusted 3-year probability of disease-free survival for no morcellation, power and nonpower morcellation was 0.54, 0.19, and 0.51, respectively (P=.15); overall survival was 0.64, 0.75, and 0.68, respectively (P=.97). None of the adjusted risk ratios for recurrence or death were significant except for death at 1 year for power and nonpower morcellation groups combined (6/33) compared with no morcellation (4/76) (5.12, 95% CI 1.33-19.76, P=.02). We had inadequate power to infer differences for all other comparisons including 3-year survival and power morcellation. CONCLUSION: Morcellation is associated with decreased early survival of women with occult leiomyosarcomas. We could not accurately assess associations between power morcellation and 3-year survival as a result of small numbers.

STUDY OBJECTIVE: To compare length of hospital stay for minilaparotomy vs laparoscopic hysterectomy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Kaiser Permanente Northern California, a large integrated health care delivery system. PATIENTS: Women >18 years of age undergoing laparoscopic or minilaparotomy hysterectomy because of benign indications from June 2009 through January 2010. INTERVENTION: Hysterectomy via minilaparotomy or laparoscopy. MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed for outcomes of interest including length of stay and surgical and demographic data. Parametric and non-parametric analyses were used to compare the 2 groups. The study was powered to detect a difference of 8 hours in length of stay. Two hundred sixty-three cases were identified as hysterectomy via minilaparotomy (n = 100) or laparoscopy (n = 163). The laparoscopy group demonstrated a significantly shorter mean (SD) length of stay (19 [14] hours vs. 42 [20] hours; p < .001) and less blood loss (126 [140] mL vs. 241 [238] mL; p < .001). The minilaparotomy group experienced a shorter procedure time (113 [47] minutes vs. 197 [124] minutes; p < .001). There was no difference between the groups insofar as patient morbidity including intraoperative and postoperative complications, emergency visits, readmissions, or repeat operations. CONCLUSION: Compared with minilaparotomy, laparoscopic hysterectomy is associated with shorter length of hospital stay, longer operating time, and no increased patient morbidity.
