Predictive Factors for Morcellation during Total Laparoscopic Hysterectomy: A Cohort Study.

OBJECTIVES: Our objective was to identify predictors of morcellation during a total laparoscopic hysterectomy (TLH). METHODS: A retrospective cohort study (Canadian Task Force classification II-2) taking place in a university hospital center in Quebec, Canada. Participants were women undergoing a TLH for a benign gynaecologic pathology from January 1, 2017, to January 31, 2019. All women underwent a TLH. If the uterus was too voluminous to be removed vaginally, surgeons favoured in-bag morcellation by laparoscopy. Uterine weight and characteristics were assessed before surgery by ultrasound or magnetic resonance imaging to predict morcellation. RESULTS: A total of 252 women underwent a TLH and the mean age was 46 ± 7 (30-71) years old. The main indications for surgery were abnormal uterine bleeding (77%), chronic pelvic pain (36%) and bulk symptoms (25%). Mean uterine weight was 325 (17-1572) ± 272 grams, with 11/252 (4%) uterus being >1000 grams and 71% of women had at least 1 leiomyoma. Among women with a uterine weight <250 grams, 120 (95%) did not require morcellation. On the opposite, among women with a uterine weight >500 grams, 49 (100%) required morcellation. In addition to the estimated uterine weight (≥250 vs. <250 grams; OR 3.7 [CI 1.8 to 7.7, P < 0.01]), having ≥ 1 leiomyoma (OR 4.1, CI 1.0 to 16.0, P = 0.01) and leiomyoma of ≥5 cm (OR 8.6, CI 4.1 to 17.9, P < 0.01) were other significant predictors morcellation in multivariate logistic regression analysis. CONCLUSIONS: Uterine weight estimated by preoperative imaging as well as the size and number of leiomyomas are useful predictors of the need for morcellation.

Evaluation of a Standardized Questionnaire for Initial Assessment of Abnormal Uterine Bleeding in Premenopausal Women.

OBJECTIVE: To assess the effect of a standardized questionnaire for premenopausal women with abnormal uterine bleeding (AUB) on clinical information collection and duration of consultation. METHODS: We conducted a before and after study involving 100 premenopausal women undergoing consultation for AUB. During stage 1, 50 consultations were recorded on a consultation sheet with no specific template. During stage 2, 50 women completed a 26-item auto-administered standardized questionnaire before the consultation, which was then reviewed with the consultant and added to the medical record. The duration of consultation was assessed in subgroups of 27 women in each stage. Two independent evaluators assessed the quality and completeness of data collected in the medical records using a score sheet developed by experts. Outcomes from both stages were compared using the t test. RESULTS: The descriptive characteristics were similar in both groups. The mean global scores of the quality and completeness of data collected improved significantly between stages 1 and 2, from 67% ± 12% to 95% ± 5% (P < 0.0001), as did medical background scores (54% ± 29% vs. 85% ± 13%; P < 0.0001) and AUB-related symptoms scores (69% ± 13% vs. 97% ± 5%; P < 0.0001). A mean reduction in duration of consultation of nearly 4 minutes was observed (24.6 ± 4.3 min vs. 20.7 ± 4.8 min; P < 0.0001). CONCLUSION: The AUB-specific standardized questionnaire improves quality and completeness of data collected in medical records and reduces duration of consultation.

Technicity in Canada: A Nationwide Whole-Population Analysis of Temporal Trends and Variation in Minimally Invasive Hysterectomies.

STUDY OBJECTIVE: The objective of our study was to provide a contemporary description of hysterectomy practice and temporal trends in Canada. DESIGN: A national whole-population retrospective analysis of data from the Canadian Institute for Health Information. SETTING: Canada. PATIENTS: All women who underwent hysterectomy for benign indication from April 1, 2007, to March 31, 2017, in Canada. INTERVENTIONS: Hysterectomy. MEASUREMENTS AND MAIN RESULTS: A total of 369 520 hysterectomies were performed in Canada during the 10-year period, during which the hysterectomy rate decreased from 313 to 243 per 100 000 women. The proportion of abdominal hysterectomies decreased (59.5% to 36.9%), laparoscopic hysterectomies increased (10.8% to 38.6%), and vaginal hysterectomies decreased (29.7% to 24.5%), whereas the national technicity index increased from 40.5% to 63.1% (p <.001, all trends). The median length of stay decreased from 3 (interquartile range 2-4) days to 2 (interquartile range 1-3), and the proportion of patients discharged within 24 hours increased from 2.1% to 7.2%. In year 2016-17, women aged 40 to 49 years had significantly increased risk of abdominal hysterectomy compared with women undergoing hysterectomy in other age categories (p <.001). Comparing women with menstrual bleeding disorders, women undergoing hysterectomy for endometriosis (adjusted relative risk [aRR] 1.36; 95% confidence interval [CI], 1.28-1.44) and myomas (aRR 2.01; 95% CI, 1.94-2.08) were at increased risk of abdominal hysterectomy, whereas women undergoing hysterectomy for pelvic organ prolapse and pelvic pain (aRR 1.47; 95% CI, 1.41-1.53) were at decreased risk. Using Ontario as the comparator, Nova Scotia (aRR 1.35; 95% CI, 1.27-1.43), New Brunswick (aRR 1.25; 95% CI, 1.18-1.32]), Manitoba (aRR 1.35; 95% CI, 1.28-1.43), and Newfoundland and Labrador (aRR 1.18; 95% CI, 1.10-1.27) had significantly higher risks of abdominal hysterectomy. In contrast, Saskatchewan (aRR 0.75; 95% CI, 0.74-0.77) and British Columbia (aRR 0.86; 95% CI, 0.85-0.88) had significantly lower risks, whereas Prince Edward Island, Quebec, and Alberta were not significantly different. CONCLUSION: The proportion of minimally invasive hysterectomies for benign indication has increased significantly in Canada. The declining use of vaginal approaches and the variation among provinces are of concern and necessitate further study.

Guideline No. 412: Laparoscopic Entry for Gynaecological Surgery.

OBJECTIVE: To evaluate the benefits and risks of laparoscopic surgery and provide clinical direction on entry techniques, technologies, and their associated complications in gynaecological surgery. TARGET POPULATION: All patients, including pregnant women and women with obesity, undergoing laparoscopic surgery for various gynaecological indications. OPTIONS: The laparoscopic entry techniques and technologies reviewed in formulating this guideline included the closed (Veress needle-pneumoperitoneum-trocar) technique, direct trocar insertion, open (Hasson) technique, visual entry systems, and disposable shielded and radially expanding trocars. OUTCOMES: Implementation of this guideline should optimize decision-making in the selection of entry technique for laparoscopic surgery. EVIDENCE: We searched English-language articles from September 2005 to December 2019 in PubMed/MEDLINE, Embase, Science Direct, Scopus, and Cochrane Library using the following MeSH search terms alone or in combination: laparoscopic entry, laparoscopy access, pneumoperitoneum, Veress needle, open (Hasson), direct trocar, visual entry, shielded trocars, radially expanded trocars, and laparoscopic complications. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Canadian Task Force on Preventive Health Care approach (Appendix A). INTENDED AUDIENCE: Surgeons performing laparoscopic gynaecological surgery. SUMMARY STATEMENTS: RECOMMENDATIONS.

Minimally Invasive Hysterectomy Rates in Québec: Trends Over the Last Decade and Predictors of Technicity.

OBJECTIVE: To assess trends and predictors of a high technicity index for hysterectomies performed in the province of Québec. METHODS: We conducted a retrospective study using the ADAM database to determine the annual number hysterectomies performed for a suspected benign condition and the surgical approach used across 81 hospitals in the province of Québec from 2007 to 2017. We calculated the technicity index for each hospital and analyzed trends in surgical approach using the Cochran-Armitage test. We used logistic regression to assess potential predictors of a high technicity index (>70%), including academic centre, urban area, high volume of hysterectomies performed, and greater number of gynaecologists per hospital. RESULTS: Fifty-nine hospitals were eligible for inclusion, representing 96 431 hysterectomies during the study period. Over the decade, the technicity index increased from 43% to 66% (P < 0.001, with a 198% increase in laparoscopic hysterectomies (from 685 to 2039 per year; P < 0.001), a 50% decrease in abdominal hysterectomies (from 5528 to 2790 per year; P < 0.001), and a 8% decrease in vaginal hysterectomies (form 3551 to 3257 per year; P < 0.001). Meanwhile, the total number of hysterectomies per year declined by 17% (P < 0.001). Being an academic centre was the only significant predictor of a high technicity index >70% (68% vs. 38%; OR 7.5; P = 0.047). CONCLUSION: Technicity is increasing in the province of Québec and the majority of hysterectomies are now performed using a minimally invasive approach. This shift has mainly occurred through an increase in the laparoscopic approach and a decrease in the abdominal approach. Academic centres are more likely to have high technicity indexes.

Morcellation During Total Laparoscopic Hysterectomies: Implications of the Use of a Contained Bag System.

OBJECTIVE: This study sought to report the feasibility and clinical implications of in-bag morcellation for total laparoscopic hysterectomy (TLH). METHODS: Women who required uterine morcellation during TLH from January 2017 to December 2018 (at the Centre Hospitalier Universitaire de Québec - CHUL, Québec, QC) were included. Women with a preoperative suspicion of malignancy were excluded (Canadian Task Force classification II-2). RESULTS: During the 2-year study period, uterine morcellation was required in 42% (106 of 252) of women undergoing TLH. Mean uterine weight of morcellated uterus was 541 ± 291 g, with 11 of 106 uteri weighing >1000 g. In-bag morcellation was attempted in 84 of 106 (79%) and successfully performed in 79 of 84 (94%) women. Failures resulted from inability to insert the specimen into the bag or apparent perforation. Uncontained morcellation was chosen for 22 of 106 (21%) women, most of whom underwent vaginal morcellation of the uterus. Total operative time was 40 minutes longer for the in-bag morcellation group (170 ± 48 vs. 130 ± 43 min; P < 0.001), although this difference can be partly explained by the higher mean uterine size compared with the uncontained morcellation group (580 ± 309 vs. 391 ± 122 g; P = 0.01). In a subgroup analysis of 16 women, the mean times of installation and extraction of the bag were estimated to be 17 ± 9 and 4 ± 3 minutes, respectively. Complications were infrequent (2 of 106) and occurred in the in-bag morcellation group. CONCLUSION: In-bag morcellation is feasible in a high proportion of women undergoing laparoscopic hysterectomy and is associated with an increase in operative time. Larger studies will be required in order to better assess the risk of complications with in-bag morcellation and the potential benefits of this technique, namely, reducing the spread of tissue.

Contained Morcellation of Very Large Uterus.

A 38-year-old woman was referred to our centre for symptomatic leiomyoma. The patient had a large uterus, heavy menstrual bleeding, and compressive symptoms refractory to medical treatments. The patient was then scheduled for total laparoscopic hysterectomy with contained morcellation. After circular colpotomy completion, a strong, folded, 4-L bag with an additional sleeve for the optics was inserted into the abdominal cavity through the vagina. The colored tabs on the edge of the bag mouth served as landmarks during bag deployment. After ensuring optimal positioning, the entire bag was fully deployed, and the specimen was placed inside. Thereafter, the coloured tabs were joined together, and a monofilament drawstring was cinched to close the bag and pulled out through the suprapubic trocar. Next, the small extra sleeve was brought up through the umbilical incision. The bag was then insufflated, and the power morcellator was inserted through the suprapubic incision. After completing the morcellation, the pneumo bag was evacuated, and knots were made in both openings of the bag to avoid spillage. The closed bag was finally removed through the vagina, with final laparoscopic closure of the vaginal vault.

No. 193-Laparoscopic Entry: A Review of Techniques, Technologies, and Complications.

OBJECTIVE: To provide clinical direction, based on the best evidence available, on laparoscopic entry techniques and technologies and their associated complications. OPTIONS: The laparoscopic entry techniques and technologies reviewed in formulating this guideline include the classic pneumoperitoneum (Veress/trocar), the open (Hasson), the direct trocar insertion, the use of disposable shielded trocars, radially expanding trocars, and visual entry systems. OUTCOMES: Implementation of this guideline should optimize the decision-making process in choosing a particular technique to enter the abdomen during laparoscopy. EVIDENCE: English-language articles from Medline, PubMed, and the Cochrane Database published before the end of September 2005 were searched, using the key words laparoscopic entry, laparoscopy access, pneumoperitoneum, Veress needle, open (Hasson), direct trocar, visual entry, shielded trocars, radially expanded trocars, and laparoscopic complications. VALUES: The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on the Periodic Health Examination. RECOMMENDATIONS AND SUMMARY STATEMENT.

[Development of technicality indices of hysterectomies in Quebec]. / Évolution de l'indice de technicité des hystérectomies au Québec

OBJECTIVE: Assess the evolution of the technicity index for hysterectomies in Québec. METHODS: We used the ADAM ( Analyse en direct des actes médicaux) database to determine the number of hysterectomies done each year within 79 hospitals in Québec from 2002 to 2009. Excluding oncologically indicated surgeries, we calculated the number of hysteretomies and the proportion performed by the vaginal route (laparoscopically assisted or not), by laparoscopu, and by laparotomy for each study year. RESULTS: We obtained complete data fo 67 (85%) of 79 hospitals, for a total of 74 210 (94%) of 79 305 hysterectomies done. We observed a decline in the total number of hysterestomies from 12 860 in 2002-2003 to 8010 in 2008-2009 (P<0.001) Furthermore, the proportion of hysterectomies done by laparoscopy increased, the proportion of vaginal hysterectomies remained stable, and the proportion of hysterectomies done by laparoscopy increased. For all of Québec, the technicity index increased from 39.9% in 2002-2003 to 44.3% in 2008-2009 (P<0.001). CONCLUSION: The number of hysterectomies is declining and the technicity index is increasing in Quebec. We believe that this can be attributed to an increased use of medical alternatives and the presence of gynaecologists better trained in advanced laparoscopic surgery.

Glucocorticoid-induced androgen inactivation by aldo-keto reductase 1C2 promotes adipogenesis in human preadipocytes.

Adipogenesis and lipid storage in human adipose tissue are inhibited by androgens such as DHT. Inactivation of DHT to 3α-diol is stimulated by glucocorticoids in human preadipocytes. We sought to characterize glucocorticoid-induced androgen inactivation in human preadipocytes and to establish its role in the antiadipogenic action of DHT. Subcutaneous and omental primary preadipocyte cultures were established from fat samples obtained in subjects undergoing abdominal surgeries. Inactivation of DHT to 3α/ß-diol for 24 h was measured in dexamethasone- or vehicle-treated cells. Specific downregulation of aldo-keto reductase 1C (AKR1C) enzymes in human preadipocytes was achieved using RNA interference. In whole adipose tissue sample, cortisol production was positively correlated with androgen inactivation in both subcutaneous and omental adipose tissue (P < 0.05). Maximal dexamethasone (1 µM) stimulation of DHT inactivation was higher in omental compared with subcutaneous fat from men as well as subcutaneous and omental fat from women (P < 0.05). A significant positive correlation was observed between BMI and maximal dexamethasone-induced DHT inactivation rates in subcutaneous and omental adipose tissue of men and women (r = 0.24, n = 26, P < 0.01). siRNA-induced downregulation of AKR1C2, but not AKR1C1 or AKR1C3, significantly reduced basal and glucocorticoid-induced androgen inactivation rates (P < 0.05). The inhibitory action of DHT on preadipocyte differentiation was potentiated following AKR1C2 but not AKR1C1 or AKR1C3 downregulation. Specifically, lipid accumulation, G3PDH activity, and FABP4 mRNA expression in differentiated preadipocytes exposed to DHT were reduced further upon AKR1C2 siRNA transfection. We conclude that glucocorticoid-induced androgen inactivation is mediated by AKR1C2 and is particularly effective in omental preadipocytes of obese men. The interplay between glucocorticoids and AKR1C2-dependent androgen inactivation may locally modulate adipogenesis and lipid accumulation in a depot-specific manner.

Uterine artery embolization complicated by uterine perforation at the site of previous myomectomy.

A 46-year-old woman had an unusual complication from uterine myoma embolization by development of extensive necrosis with subsequent uterine perforation at the location of a previous myomectomy. We suggest that a scarred uterus may be a risk factor for uterine fibroid embolization complications, such as uterine necrosis.

Effect of Postoperative Hormonal Suppression on Fertility in Patients With Endometriosis After Conservative Surgery: A Systematic Review and Meta-analysis.

OBJECTIVE: To evaluate the effect of hormonal suppression on fertility when administered to infertile patients or patient wishing to conceive after surgery for endometriosis. DATA SOURCES: A systematic search of MEDLINE, EMBASE, CENTRAL and ClinicalTrials.gov was performed by two independent reviewers from the databases' inception until December 2020. METHODS OF STUDY SELECTION: We included randomized controlled trials comparing any suppressive hormonal therapy to an inactive control (placebo or absence of treatment) after conservative surgery for endometriosis. Studies that did not report fertility outcomes after surgery were excluded. TABULATION, INTEGRATION AND RESULTS: This systematic review and meta-analysis was registered in PROSPERO. Two reviewers extracted data and assessed the risk of bias as well as the strength of evidence using GRADE (Grading of Recommendations, Assessment, Development and Evaluation) methodology. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines were followed. Relative risks (RRs) were pooled by quantitative random effect meta-analysis. From 3,138 citations, 19 trials (2,028 patients) were included. Overall, no difference was observed between the treatment and the control group for pregnancy (RR 1.15; 95% CI 1.00-1.32) and live births (RR 1.05; 95% CI 0.84-1.32). When pooling all hormonal therapies, the duration of administration of postoperative therapy was identified as a substantial source of heterogeneity between studies (I2 difference=74%) with increased chances of pregnancy compared with control when administered for at least 3 months (RR 1.22; 95% CI 1.04-1.43). Gonadotropin-releasing hormone (GnRH) agonists (14 trials, 1,721 patients) were associated with increased chances of pregnancy compared with placebo or no treatment (RR 1.20; 95% CI 1.03-1.41; I2=25%). Data were limited for other hormonal treatments with no significant difference between groups. Subgroup analyses taking into account the use of fertility treatments (insemination or in vitro fertilization), stages of the disease and risk of bias of included trials did not modify the results. CONCLUSION: Postoperative hormonal suppression should be considered on a case-by-case basis to enhance fertility while balancing this benefit with the risks of delaying conception. If chosen, GnRH agonists would be the treatment of choice, and a duration of at least 3 months should be favored. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, CRD42021224424.
