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.

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.

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.

Endometrial ablation or resection versus levonorgestrel intra-uterine system for the treatment of women with heavy menstrual bleeding and a normal uterine cavity: a systematic review with meta-analysis.

BACKGROUND: Endometrial ablation/resection and the levonorgestrel intra-uterine system (LNG-IUS) are well-established treatment options for heavy menstrual bleeding to avoid more invasive alternatives, such as hysterectomy. OBJECTIVE: The aim was to compare the efficacy and safety of endometrial ablation or resection with the LNG-IUS in the treatment of premenopausal women with heavy menstrual bleeding and to investigate sources of heterogeneity between studies. SEARCH METHODS: We searched the databases MEDLINE, EMBASE, CENTRAL, Web of Science, Biosis and Google Scholar as well as citations and reference lists published up to August 2019. Two authors independently screened 3701 citations for eligibility. We included randomized controlled trials published in any language, comparing endometrial ablation or resection to the LNG-IUS in the treatment of premenopausal women with heavy menstrual bleeding and a normal uterine cavity. OUTCOMES: Thirteen studies (N = 884) were eligible. Two independent authors extracted data and assessed the quality of included studies. Random effect models were used to compare the modalities and evaluate sources of heterogeneity. No significant differences were observed between endometrial ablation/resection and the LNG-IUS in terms of subsequent hysterectomy (primary outcome, risk ratio (RR) = 1.13, 95% CI 0.60 to 2.11, P = 0.71, I2 = 14%, 12 studies, 726 women), satisfaction, quality of life, amenorrhea and treatment failure. However, side effects were less common in women treated with endometrial ablation/resection compared to the LNG-IUS (RR = 0.52, 95% CI 0.37 to 0.71, P < 0.001, I2 = 0%, 10 studies, 580 women). Three complications were reported in the endometrial ablation/resection group and none in the LNG-IUS group (P = 0.25). Mean age of the studied populations was identified as a significant source of heterogeneity between studies in subgroup analysis (P = 0.01). In fact, endometrial ablation/resection was associated with a higher risk of subsequent hysterectomy compared to the LNG-IUS in younger populations (mean age ≤ 42 years old, RR = 5.26, 95% CI 1.21 to 22.91, P = 0.03, I2 = 0%, 3 studies, 189 women). On the contrary, subsequent hysterectomy seemed to be less likely with endometrial ablation/resection compared to the LNG-IUS in older populations (mean age > 42 years old), although the reduction did not reach statistical significance (RR = 0.51, 95% CI 0.21 to 1.24, P = 0.14, I2 = 0%, 5 studies, 297 women). Finally, sensitivity analysis taking into account the risk of bias of included studies and type of surgical devices (first and second generation) did not modify the results. Most of the included studies reported outcomes at up to 3 years, and the relative performance of endometrial ablation/resection and LNG-IUS remains unknown in the longer term. WIDER IMPLICATIONS: Endometrial ablation/resection and the LNG-IUS are two excellent treatment options for heavy menstrual bleeding, although women treated with the LNG-IUS are at higher risk of experiencing side effects compared to endometrial ablation/resection. Otherwise, younger women seem to present a lower risk of eventually requiring hysterectomy when treated with the LNG-IUS compared to endometrial ablation/resection.

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.

Imaging for Polyps and Leiomyomas in Women With Abnormal Uterine Bleeding: A Systematic Review.

OBJECTIVE: To evaluate the accuracy of saline infusion sonohysterography in comparison with transvaginal ultrasonography for diagnosing polyps and submucosal leiomyomas in women with abnormal uterine bleeding. DATA SOURCES: We searched the databases MEDLINE, EMBASE, CENTRAL, and ClinicalTrials.gov as well as citations and reference lists to the end of November 2015. METHODS OF STUDY SELECTION: Two authors screened 5,347 citations for eligibility. We included randomized controlled trials or prospective cohort studies published in English, assessing the accuracy of saline infusion sonohysterography and transvaginal ultrasonography for diagnosing polyps and submucosal leiomyomas in women with abnormal uterine bleeding. We considered studies using histopathologic specimens obtained at either hysteroscopy or hysterectomy as criterion standard. TABULATION, INTEGRATION, AND RESULTS: Twenty-five studies were eligible. Two authors extracted data and assessed the quality of included studies. Bivariate random-effects models were used to compare the different tests and evaluate sources of heterogeneity. Saline infusion sonohysterography was superior to transvaginal ultrasonography with pooled sensitivity and specificity of 0.92 and 0.89 compared with 0.64 and 0.90, respectively (P<.001). Transvaginal ultrasound sensitivity for diagnosing polyps was particularly low (0.51). Saline infusion sonohysterography was also compared with hysteroscopy in seven studies and had similar sensitivity but inferior specificity (0.93 and 0.83 compared with 0.95 and 0.90, respectively, P=.007). All three procedures were well-tolerated by women. Saline infusion sonohysterography was successfully completed in 95% of women. Technical variations such as the use of balloon catheters were not found to affect diagnostic accuracy. CONCLUSION: Transvaginal ultrasonography lacks sensitivity to be used alone to exclude the presence of polyps and leiomyomas in women with abnormal uterine bleeding. Although less specific than hysteroscopy, saline infusion sonohysterography offers a similar detection rate and permits concomitant visualization of the ovaries and myometrium. Cost, convenience, and tolerability of different imaging techniques require further evaluation.

Low vs Standard Pressures in Gynecologic Laparoscopy: a Systematic Review.

BACKGROUND: The optimal intraperitoneal pressure during laparoscopy is not known. Recent literature found benefits of using lower pressures, but the safety of doing abdominal surgery with low peritoneal pressures needs to be assessed. This systematic review compares low with standard pneumoperitoneum during gynecologic laparoscopy. DATABASE: We searched Medline, Embase, and the Cochrane Library for randomized controlled trials comparing intraperitoneal pressures during gynecologic laparoscopy. Two authors reviewed references and extracted data from included trials. Risk ratios, mean differences, and standard mean differences were calculated and pooled using RevMan5. Of 2251 studies identified, three were included in the systematic review, for a total of 238 patients. We found a statistically significant but modest diminution in postoperative pain of 0.38 standardized unit based on an original 10-point scale (95% confidence interval [CI], -0.67 to -0.08) during the immediate postoperative period when using low intraperitoneal pressure of 8 mm Hg compared with ≥ 12 mm Hg and of 0.50 (95% CI, -0.80 to -0.21) 24 hours after the surgery. Lower pressures were associated with worse visualization of the surgical field (risk ratio, 10.31; 95% CI, 1.29-82.38). We found no difference between groups over blood loss, duration of surgery, hospital length of stay, or the need for increased pressure. CONCLUSION: Low intraperitoneal pressures during gynecologic laparoscopy cannot be recommended on the behalf of this review because improvement in pain scores is minimal and visualization of the surgical field is affected. The safety of this intervention as well as cost-effectiveness considerations need to be further studied.
