Objective To assess variation in the route of hysterectomy over 7 years and to assess regional variation in practice. Design Retrospective cohort study. Setting English NHS Hospitals 2011–2017. Population 230 876 patients having a hysterectomy for six diagnostic categories (endometrial cancer, endometriosis and pain, menstrual disorders, fibroids, benign adnexal masses, and ‘other’) identified from Hospital Episode Statistics. Methods The proportion of hysterectomies carried out by each route was calculated for each year overall and for each primary diagnosis by year. Comparisons between 2011 and 2017 were via chi‐square test. Rank correlation coefficients were calculated to assess trends over the study period. Analysis of regional variation in practice was restricted to 2017. A multivariable logistic regression was performed to obtain crude and adjusted odds of having a minimal access hysterectomy. Main outcome measures The proportion of abdominal, vaginal, laparoscopic, and failed laparoscopic procedures for each primary diagnosis by study year. Odds of a minimal access hysterectomy in 2017. Results The proportion of hysterectomies performed laparoscopically increased from 20.2% in 2011 to 47.2% in 2017, as did the proportion of failed laparoscopic procedures; 1.7% in 2011 to 2.8% in 2017. The proportion of abdominal hysterectomies decreased from 70.4% in 2011 to 46.5% in 2017. There was a smaller decrease in vaginal procedures from 7.8% in 2011 to 3.5% in 2017. Regional variation in the route of hysterectomy was demonstrated in 2017, which persisted when adjusted for confounding factors. Conclusions The proportion of laparoscopic procedures has increased, and it was the commonest route of hysterectomy for this cohort in 2017. There were significant regional differences in route of hysterectomy in 2017. Tweetable abstract Increasing laparoscopic hysterectomy and decreasing abdominal hysterectomy rates from 2011 to 2017 with regional variation in practice.
Objectives To assess the inter‐rater agreement and reliability of using subjective pattern recognition for diagnosing endometrial cancer (EC) on ultrasound in women with postmenopausal bleeding (PMB). Methods This was a prospective cross‐sectional study conducted at a gynecological rapid‐access clinic, between October 2016 and December 2017, in which consecutive women with PMB and endometrial thickness of ≥ 4.5 mm on transvaginal ultrasound examination were included. Women on hormone replacement therapy or tamoxifen and those with a history of primary gynecological malignancy were excluded. Two raters independently performed ultrasound examinations, blinded to each other's findings, and classified women as having uniformly thickened endometrium, benign endometrial polyp or EC, using subjective pattern recognition. Inter‐rater reliability of ultrasound diagnosis was assessed using Cohen's kappa (κ) statistic. All women subsequently underwent either outpatient endometrial biopsy, hysteroscopy or hysterectomy. Results Forty women were included in the study, with a median age of 61 (interquartile range (IQR), 57–69) years and a median endometrial thickness of 11.0 (IQR, 6.2–20.3) mm. Final histological analysis confirmed 16 (40%) women with EC, 16 (40%) with benign endometrial polyp, four (10%) with atrophic endometrium, three (8%) with proliferative endometrium and one (3%) with endometrial hyperplasia. Inter‐rater agreement for the ultrasound diagnoses of uniformly thickened endometrium, benign endometrial polyp and EC was 14/16 (87.5%), 22/30 (73.3%) and 28/34 (82.4%), respectively; inter‐rater reliability was good (κ = 0.69; 95% CI, 0.49–0.88). When the ultrasound diagnoses were grouped as either cancer or no cancer, inter‐rater agreement was 85% and inter‐rater reliability was good (κ = 0.78; 95% CI, 0.61–0.95). Rater A correctly identified 14/16 cases of EC and Rater B identified 15/16. EC was misdiagnosed as benign polyps on ultrasound in two women by Rater A and in one woman by Rater B. The overall accuracies of Rater A and Rater B in differentiating between benign endometrial pathologies and malignancy were 90% and 90%, respectively. Conclusions Our results show good inter‐rater reliability of subjective pattern recognition in diagnosing uniformly thickened endometrium, benign endometrial polyp and EC on ultrasound in women with PMB. Our findings should facilitate wider use of subjective pattern recognition in routine clinical practice. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.
Objective: To develop and validate novel prediction models to personalise the risk of conversion from laparoscopic to open hysterectomy in benign conditions.
