Risk of hysterectomy at the time of myomectomy: an underestimated surgical risk

OBJECTIVE

To evaluate the risk of hysterectomy at the time of myomectomy and the associated 30-day postoperative morbidity.

DESIGN

Cohort study.

PATIENTS

Patients who underwent myomectomies identified from the American College of Surgeons' National Surgical Quality Improvement Program from 2010 to 2021.

INTERVENTION

Unplanned hysterectomy at the time of a myomectomy procedure.

MAIN OUTCOME MEASURES

The Current Procedural Terminology codes were used to identify myomectomies performed with or without concurrent hysterectomy. Preoperative characteristics and morbidity outcomes were obtained. The univariate analysis was performed using the chi-square and Fisher exact tests, as appropriate. Multivariate logistic regression reported risk factors for individuals who underwent hysterectomy at the time of myomectomy. P values of <.05 were considered statistically significant.

RESULTS

A total of 13,213 individuals underwent myomectomy, and 399 (3.0%) had a hysterectomy performed during myomectomy. Concurrent hysterectomy was most frequently performed with the laparoscopic approach (7.1%), followed by the abdominal (3.2%) and hysteroscopic (1.9%) approaches. Age ≥43 years, obesity class II and higher, American Society of Anesthesiologists (ASA) class greater than II, tobacco use, longer operative time (>85 minutes), and laparoscopic approach were associated with a significantly increased risk of hysterectomy. When adjusting for age, body mass index, race, ASA class, case type, surgical approach, operative time, preoperative transfusion, preoperative hematocrit, and high fibroid burden, an increased odds of hysterectomy was noted for white race, longer operative time, ASA class III or higher, obesity, laparoscopic approach, and low fibroid burden. Patients who underwent concurrent hysterectomy had a longer median length of hospital stay (2 vs. 1 day), longer median operative time (161 vs. 126 minutes), increased intraoperative/postoperative blood transfusions (14.5% vs. 9.0%), and higher rates of organ/space surgical site infections (1.5% vs. 0.5%) and return to surgery (2.0% vs. 0.7%) than those who did not (P<.05). The risk of a major complication within 30 days of myomectomy increased in patients who underwent concurrent hysterectomy after adjusting for relevant confounders (adjusted odds ratio, 2.4; 95% confidence interval, 1.8-3.2).

CONCLUSION

The risk of hysterectomy during a myomectomy is higher than previously reported. The patient age of ≥43 years, obesity, white race, ASA class III or higher, longer operative time, and laparoscopic approach were associated with higher odds of hysterectomy. Identification of patients with these risk factors can aid in patient counseling and surgical planning, which may help reduce the unexpectedly high rates of hysterectomy at planned myomectomy.

Physicians' assessment of complications after gynecological surgery in Sweden: The GYNCOM survey

INTRODUCTION

Complications after gynecological surgery in Sweden are registered in the well-established Swedish National Quality Register of Gynecological Surgery, GynOp. The aim of this study was to analyze interrater reliability in assessing complications according to the methods in GynOp, and to explore physicians' perceptions of registering complications.

MATERIAL AND METHODS

A digital survey was sent to gynecologists and residents in gynecology in Sweden. Participating clinics were recruited through the Swedish network for national clinical studies in Obstetrics and Gynecology, SNAKS. Twenty fictional cases, intended to represent normal postoperative course, failure to cure, and varying degrees of complications, were developed by the research group. The clinical scenarios included abdominal and laparoscopic surgery of the uterus and adnexa, vaginal hysterectomies, as well as hysteroscopy. The respondents graded each case on the presence of a complication (yes/no). Type of complication, severity, and what action the complication required according to Clavien-Dindo was registered if a complication was acknowledged, according to the method in GynOp. Interrater reliability and the opinions of the respondents were presented descriptively. More than 80% of respondents making the same assessment was considered as agreement.

RESULTS

The response rate was 41%, with 104 responding physicians from 16 gynecological clinics. Type and severity of complication was considered relevant to register by 88% and 89% of respondents, respectively. Agreement on whether the case described a complication was >80% in 85% (17/20) of cases and agreement using the Clavien-Dindo classification was >90% in 80% (16/20) of cases. There was high agreement in assessments of classically severe complications, such as pulmonary embolism and ureteral damage, in both presence of complication and severity, as well as Clavien-Dindo (>90% for all methods). Cases with agreement <80% on whether the case described a complication were bordering between normal postoperative course and minor complication.

CONCLUSIONS

This study provides validation for the methods used to register complications after gynecological surgery according to the GynOp register, including the use of Clavien-Dindo in gynecology. However, the results indicate a need to define what should be considered symptoms inherent to each type of surgery.

Multi-Institutional Trends in Gynecological Robotic Surgery in India: A Real-World Scenario

Background Robot-assisted laparoscopic surgery in gynecology has grown exponentially compared to laparoscopic surgery. The probable reasons for the increased uptake of robotics are a shorter learning curve, three-dimensional vision, and increased dexterity compared to laparoscopic surgery, and precise surgery as compared to open surgery. This study compares the time trends of various parameters in robotic gynecological surgery in India over a decade. Material and methods In India, a retrospective analysis of all robot-assisted laparoscopic surgery for gynecologic diseases in five tertiary care hospitals was conducted between July 2011 and June 2021. Data were collected regarding demographic profiles, clinical and disease characteristics, and indications for surgery. Details related to surgery were collected, such as the number of ports, console and docking time, the procedure performed, total operative time, average blood loss, blood transfusion, and length of hospital stay. All the parameters collected were grouped into five years, and a comparison was made between the first five years (2011-2015) and the second five years (2016-2021). Statistical analysis, including descriptive statistics and trend analysis, was performed. Results During the 10 years, the total number of cases included was 1,501, out of which 764 were benign cases and 737 were pre-malignant/malignant cases. The common indications were uterine leiomyoma (31.2%) and carcinoma endometrium (28%). The mean age for benign cases was significantly lower than that for malignant cases (40.84 years and 55.42 years, respectively). Mean blood loss was significantly lower for benign indications (97.48 mL) than for oncological surgery (184.67 mL) and needed fewer transfusions. The mean length of stay (LOS) for benign (2.07 days) and malignant/ pre-malignant cases (2.32 days) and the mean BMI for benign (28.40) and for oncological patients (28.47) were similar in both groups. The docking time reduced significantly in the last five years. Conclusion The current retrospective study demonstrates an increasing uptake of robotic technology in gynecological surgery in India. Of the total cohort of cases, 70.9% of patients underwent gynecological robotic surgery in the last five years. A burst of adaptability happened for malignant cases in 2017 and benign cases in 2018, probably due to the increased availability of robotic platforms and improved awareness of technology and training among medical professionals. The number of cases has grown exponentially over the last five years in both benign and malignant/ pre-malignant scenarios; however, there has been a downward trend in the robotic surgery performed in the previous couple of years due to the uncertainty of the COVID pandemic.

Risk Assessment Model for Complications in Minimally Invasive Hysterectomy: A Pilot Study

Objective: To estimate the rate of intra-operative and postoperative complications, and to define the risk of 30-day major postoperative complications (Clavien-Dindo > 2) according to the presence of one of 10 different variables of minimally invasive (MI) hysterectomy; and then to create a risk assessment model easily applicable in clinical practice. Methods: A single center single arm retrolective study. Data of consecutive patients who have undergone MI hysterectomy for gynaecologic disorders between May 2018 and April 2021 were analyzed. Perioperative surgical outcomes, occurrence of intra- and postoperative complications, and readmissions within 30 days from surgery were registered. Univariate and multivariable analyses were performed to determine the factors associated with major postoperative complications. Results: Over the study period, 445 patients were included in the study. The majority of patients developed a minor event, while major complications (grade III) were required in 14 patients. None of the patients showed a grade IV or V complication. Univariate analysis was performed on patients who had developed intra- or postoperative complications from those who did not experience complications. Body mass index (BMI) (p-value 0.045) and surgeon’s experience (p-value 0.015) were found to be associated with a different surgery time. Regarding major postoperative complications, a statistically significant association was found for the variables: BMI (p-value 0.006), previous abdominal surgery (p-value 0.015), and surgeon’s experience (p-value 0.035) in the univariate analysis. Also in the multivariate analysis, the risk of major postoperative complications was higher in these three different variables. BMI, previous surgery, and surgeon’s experience were inserted in a reproducible risk assessment model in order to stratify the risk of major postoperative complications. Conclusions: We proposed a risk assessment model including factors not previously considered in the literature: the standardization of the surgical technique, the surgeon’s experience, the best MI approach (laparoscopy or robot-assisted), and previous abdominal surgery are crucial tools to consider. Further prospective studies with a larger population sample are needed to validate these preliminary evaluations for patients undergoing MI hysterectomy.

Hysterectomy for cervical intraepithelial neoplasia: A retrospective observational multi-institutional study

OBJECTIVE

To analyze the clinical management, the outcomes, and the trend in hysterectomy rates (HR) in patients who underwent this procedure for cervical intraepithelial neoplasia (CIN).

METHODS

Multicentric retrospective observational study conducted on 242 patients who underwent hysterectomy for CIN between 2010 and 2020 in nine Italian institutions. Hysterectomy for invasive or micro-invasive neoplasia, sub-total hysterectomy, or trachelectomy were excluded.

RESULTS

A significant increase in the trend of HR for CIN was recorded (P = 0.002, r = 0.81; C.I. 95%: 0.415-0.949); HR increased from 0.46% in the year 2010 to 3.32% in 2020. The mortality rate was 0.4%, and 5% had operative complications. On definitive histopathology examination, a CIN of any grade was recorded in 71.5% of cases, and an occult invasive cancer in 1.24%. No pathology or CIN1 was found in 26.8% of cases, suggesting over treatment. During follow-up, a vaginal lesion was recorded in 5% of cases.

CONCLUSION

A significant increase in the number of hysterectomies performed for CIN in the last 10 years was recorded. Hysterectomy for CIN can lead to complications, risk of the onset of vaginal lesions, and risk of overtreatment, and remains, in the first instance, an unacceptable treatment, to be proposed only after adequate counseling.

Uterine Artery Embolisation of Fibroids and the Phenomenon of Post-Embolisation Syndrome: A Systematic Review

Post-embolisation syndrome (PES) is a prevalent complication that occurs in patients following uterine artery embolisation (UAE) for the treatment of uterine fibroids. The aetiology of PES remains incompletely understood, although postulated to result secondary to tissue infarction resulting in release of inflammatory mediators. We followed PRISMA guidelines and performed a systematic review of studies of PES following UAE from inception to October 2022. Our published protocol was prospectively registered. Our search yielded 54 results. We reviewed 22 full texts, and nine articles were included. Observational studies comprised 6/9 relevant studies, with 5/9 retrospective design. The rate of PES was documented in 5/8 studies (excluding case report) with a reported incidence ranging from 4-34.6%. Five of the nine studies studies postulated that the aetiological basis of PES is inflammatory related. Further research is necessary to advance our understanding of PES to define the biological basis of the syndrome with more certainty and gain a consensus on peri-procedure management to reduce incidence and improve patient outcomes.

Effects of hysterectomy on pelvic floor function and sexual function-A prospective cohort study

INTRODUCTION

Hysterectomy is one of the most common major surgical procedures in women. The effects of hysterectomy on pelvic floor and sexual function are uncertain. Our objective was to investigate the effects of hysterectomy for benign indications on pelvic floor and sexual function and to compare different modes of surgery.

MATERIAL AND METHODS

We performed a prospective clinical cohort study. In all, 260 women scheduled for hysterectomy answered validated questionnaires (Pelvic Floor Impact Questionnaire, Pelvic Floor Distress Inventory and Female Sexual Function Index). Participants were followed 6 months and 1 year after surgery. Data were analyzed using nonparametric statistics and mixed effect models.

RESULTS

Women with subtotal hysterectomy, vaginal hysterectomy, laparoscopic assisted vaginal hysterectomy, and previous prolapse/incontinence surgery were excluded from further analysis, leaving the remaining cohort to 242 patients. The response rate at 6 months and 1 year follow-up was 180/242 (74.3%) and 169/242 (69.8%), respectively. There was an improvement of pelvic floor function at both follow-ups; mean score of Pelvic Floor Impact Questionnaire at baseline was 42.5 (51.7), at 6 months 19.9 (42.2) and at 1 year 23.7 (50.3) (p < 0.001). The mean score of Pelvic Floor Distress Inventory at baseline was 69.6 (51.1), at 6 months 49 (43.2) and at 1 year 49 (43.2) (p < 0.001). There was an improvement of sexual function after 6 months (mean score of Female Sexual Function Index at baseline 17.9 [SD 11.7] and at 6 months 21.0 [SD 11.7]) (p < 0.001). There was no difference in pelvic floor or sexual function when comparing surgical techniques.

CONCLUSIONS

Robotic assisted laparoscopic hysterectomy, laparoscopic hysterectomy and abdominal hysterectomy improve pelvic floor function to the same extent at 6 months and 1 year after surgery. There was an overall improvement of sexual function 6 months after hysterectomy, but this did not persist after 1 year.

Comparing Characteristics of and Postoperative Morbidity after Hysterectomy for Endometriosis versus other Benign Indications: A NSQIP Study

STUDY OBJECTIVE

Compare the difference in postoperative morbidity for benign total hysterectomy by indication.

DESIGN

Retrospective cohort.

SETTING

United States hospitals participating in the American College of Surgeons National Surgical Quality Improvement Project database from 2018 to 2019.

PATIENTS

Patients undergoing total hysterectomy for benign indications age 18 to 55 years old.

INTERVENTIONS

Univariate comparisons were made between patients with hysterectomies for endometriosis and other benign indications. Unadjusted and adjusted logistic regression models were used to investigate the association between primary outcomes and hysterectomy indication; covariates in the adjusted model include age, race, ethnicity, and route.

MEASUREMENTS AND MAIN RESULTS

A total of 29 742 women underwent hysterectomies, of which 3596 (12.1%) were performed for endometriosis. Patients undergoing hysterectomy for endometriosis were likely to be younger, were predominately White, and had less comorbidities. They were also more likely to have previous abdominal surgery, have previous pelvic surgery, undergo a laparoscopic approach, and undergo lysis of adhesions (all p <.001). Overall length of stay (≥1 day 73.1% vs 78.6%; p = .983) and operative time (median 118.0 vs 125.0 minutes; p <.001) were similar in both groups. Examining primary outcomes, patients with endometriosis were more likely to experience major morbidity (3.8% vs 3.4%; adjusted odds ratio [OR], 1.25; p = .033), with no difference in minor or overall morbidity (5.8% vs 6.9% [p = .874] and 8.8% vs 9.4% [p = .185], respectively). There were two 30-day mortalities, none in the endometriosis group. Patients with endometriosis were more likely to develop deep surgical site infection (SSI)/organ-space infection (2.3% vs 1.6%; OR, 1.42; p = .024) and less likely to receive blood transfusion (1.8% vs 3.0%; OR, 0.58; p <.001). There was no difference in occurrence of superficial SSI, sepsis, venous thromboembolism, readmission, or reoperation between groups.

CONCLUSION

Patients undergoing hysterectomy for endometriosis were more likely to experience major morbidity and deep SSI, although overall major morbidity is rare.

Outcomes of Women Undergoing Excision of the Retained Cervix After Supracervical Hysterectomy

OBJECTIVE

To characterize the indications for and complication rates of excision of the retained cervix after supracervical hysterectomy.

METHODS

We performed a retrospective cohort study of women undergoing excision of the retained cervix after supracervical hysterectomy in the 2010-2014 National Inpatient Sample. International Classification of Diseases, Ninth Revision codes were used to identify indication for the procedure and surgical complications. We weighted the hospital-level data to obtain nationwide estimates of patient characteristics, surgical complications, and length of stay.

RESULTS

Nationwide, 1,140 women underwent excision of the retained cervix after hysterectomy. Their mean age was 49 years, and the majority were White and privately insured. Leiomyomas were the most commonly coded indication (35%, 95% CI 29-42), followed by prolapse (14%, 95% CI 9-18). Eighteen percent (95% CI 13.0-23.1) were performed for malignancy, including 5.3% (95% CI 2.3-8.2) for cervical cancer. Only 11.5% (95% CI 7.3-15.6) of cases were performed laparoscopically. The overall complication rate was high (38%, 95% CI 32-45), particularly for bleeding complications (26%, 95% CI 20-31) and transfusion (15%, 95% CI 11-20). Gastrointestinal complication rates were second highest (8%, 95% CI 5-12); ileus was the most common gastrointestinal complication (7.0%, 95% CI 3.7-10.4). The median length of stay was 2 days (range 0-34).

CONCLUSION

Women who undergo excision of the retained cervix after supracervical hysterectomy experience high rates of complications, the most common of which was bleeding. Patient counseling regarding removal of the cervix at the time of hysterectomy should include this information.

Consensus on safe implementation of vaginal natural orifice transluminal endoscopic surgery (vNOTES)

STUDY OBJECTIVE

The first ever report of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for benign gynaecological was reported in 2012. There has been an exponential uptake of the number of surgeons performing such procedures worldwide with no official guidance to ensure the safe implementation of this technique into gynaecological practice due its recency. The objective of this study is to report an international consensus-based statement to help guide a basis for adopting vNOTES into clinical practice.

STUDY DESIGN

The consensus-based statement was developed amongst 39 international experts using the Delphi methodology over three successive rounds. Consensus was pre-defined as an agreement of 80% or more by the experts. Consensus sought over eight key concepts pertaining to vNOTES including patient selection, perioperative management, surgical technique, instruments, anatomy, training, registries and trials and definition of the surgical technique. Recommendations from an expert anaesthetist and urogynaecologist were also sought to give a broader perspective with respect to the implementation of vNOTES.

RESULTS

Fifty nine international surgeons were invited to participate and 39 (66%) agreed to participate based on being involved in a minimum of 20 vNOTES procedures. They were from 13 countries across 5 continents (Europe, North America, South America, Australia and Asia). Participation was 100% on all three rounds. Overall, consensus was reached in 50 of the 56 questions (89%) with the remaining 6 questions where consensus was not reached pertaining to the domain of patient selection.

CONCLUSION

An international expert based vNOTES statement is presented here to help guide adoption of vNOTES based on the experience of early adopters. Consensus was achieved on most components of this consensus statement. Given the recency of this technique, until high-level evidence becomes available, this statement provides an appropriate guidance to the safe implementation of vNOTES into gynaecological practice.
