Pelvic floor functional outcomes after total abdominal vs total laparoscopic hysterectomy for endometrial cancer

Pre- vs Post-Operative Levator Ani Subtended Volume in Patients Undergoing Hysterectomy: A Comparative Imaging Study

INTRODUCTION AND HYPOTHESIS

The effects of hysterectomy on pelvic floor function remain uncertain, with the levator ani muscle (LAM) playing a critical role in pelvic support. The levator ani subtended volume (LASV) is an objective measure of the LAM's anatomical volume, derived from magnetic resonance imaging (MRI). This study was aimed at assessing the consistency between MRI and computed tomography (CT) in quantifying LASV, and to investigate the effect of hysterectomy on the LAM.

METHODS

This retrospective study analyzed a cohort of 55 hysterectomy patients, utilizing pre-operative pelvic MRI and post-operative CT scans to measure the LASV. To evaluate the consistency between MRI and CT, the study employed the intraclass correlation coefficient and Bland-Altman agreement analysis in a subset of 32 patients with both pre-operative scans. A paired-samplet test was used to analyze LASV changes pre- and post-hysterectomy, and linear regression analysis was performed to account for potential risk factors that may influence post-operative LASV.

RESULTS

High consistency between MRI and CT in measuring LASV was found, with an ICC of 0.911. We observed a significant increase in LASV following hysterectomy, with mean volume pre- and post-operatively of 16.66 cm3 and 18.87 cm3 respectively. Age and body mass index were significant predictors of post-hysterectomy LASV, whereas parity and the type of hysterectomy had no significant impact.

CONCLUSIONS

Hysterectomy significantly affects the LAM, resulting in an increase in post-operative LASV. Moreover, this study verifies that MRI and CT can be used interchangeably for LASV measurements in clinical practice.

Pelvic floor and sexual function 3 years after hysterectomy - A prospective cohort study

INTRODUCTION

Long term effects after hysterectomy, such as a worsening of pelvic floor and sexual function, have been studied with diverse results. Therefore, we investigated the long-term effects of hysterectomy for benign indication on pelvic floor and sexual function as well as differences in outcome depending on mode of hysterectomy.

MATERIAL AND METHODS

In a prospective clinical cohort study, we included 260 women scheduled for hysterectomy who answered validated questionnaires; pelvic floor impact questionnaire (PFIQ-7), pelvic floor distress inventory (PFDI-20) and female sexual function index (FSFI). Participants were followed up to 3 years after surgery. Nonparametric statistics and mixed effect models were used in analyses of the data.

RESULTS

After exclusions, 242 women remained in the study, with a response rate at the 3-year follow-up of 154/242 (63.6%) for all questionnaires. There was an improvement of pelvic floor function with a mean score of PFIQ-7 at baseline of 42.5 (SD 51.7) and at 3 years 22.7 (SD 49.4), (p < 0.001) and mean score of PFDI-20 at baseline was 69.6 (SD 51.1) and at 3 years 56.2 (SD 54.6), (p = 0.001). A deterioration of sexual function was seen among the sexually active women after 3 years with a mean score of FSFI at baseline 25.2 (SD 6.6) and after 3 years 21.6 (SD 10.1), (p < 0.001). However, this was not consistent with the unaltered sexual function for the whole cohort. No difference in pelvic floor or sexual function was detected when comparing robotic assisted laparoscopic hysterectomy, laparoscopic hysterectomy and abdominal hysterectomy.

CONCLUSIONS

Three years after surgery robotic assisted laparoscopic hysterectomy, total laparoscopic hysterectomy and abdominal hysterectomy improve pelvic floor function to the same extent. Among the sexually active women, a decline of sexual function was seen after 3 years, not consistent with the entire cohort and independent of surgical methods. Whether this is a trend associated with aging or menopausal transition remains to be studied.

Pelvic floor dysfunction in gynecologic cancer survivors

Pelvic floor dysfunction (PFD) is a common complication in gynecologic cancer survivors (GCS) and is now a worldwide medical and public health problem because of its great impact on the quality of life of GCS. PFD after comprehensive gynecologic cancer treatment is mainly reflected in bladder function, rectal function, sexual dysfunction and pelvic organ prolapse (POP), of which different types of gynecologic cancer correspond to different disease incidence. The prevention strategies of PFD after comprehensive gynecologic cancer treatment mainly included surgical treatment, physical therapy and behavioral guidance, etc. At present, most of them still focus on physical therapy, mostly using Pelvic Floor Muscle Training (PFMT) and multi-modal PFMT treatment of biofeedback combined with electrical stimulation, which can reduce the possibility of PFD after surgery in GCS to some extent. This article reviews the clinical manifestations, causes and current research progress of prevention and treatment methods of PFD after comprehensive treatment for GCS.

Concurrent Surgery for Locoregional Gynecologic Cancers and Pelvic Floor Disorders in a Population of Patients With Medicare Insurance

OBJECTIVE

To estimate the rate of concurrent surgery for locoregional gynecologic cancer and pelvic organ prolapse-urinary incontinence (POP-UI) and to assess the rate of surgery for POP-UI within 5 years for those who did not undergo concurrent surgery.

METHODS

This is a retrospective cohort study. The SEER-Medicare data set was used to identify cases of local or regional endometrial, cervical, and ovarian cancer diagnosed from 2000 to 2017. Patients were followed up for 5 years from diagnosis. We used χ 2 tests to identify categorical variables associated with having a concurrent POP-UI procedure with hysterectomy or within 5 years of hysterectomy. Logistic regression was used to calculate odds ratios and 95% CIs adjusted for variables statistically significant (α=.05) in the univariate analyses.

RESULTS

Of 30,862 patients with locoregional gynecologic cancer, only 5.5% underwent concurrent POP-UI surgery. Of those with a preexisting diagnosis related to POP-UI, however, 21.1% had concurrent surgery. Of the patients who had a diagnosis of POP-UI at the time of initial surgery for cancer and who did not undergo concurrent surgery, an additional 5.5% had a second surgery for POP-UI within 5 years. The rate of concurrent surgery remained constant over the time period (5.7% in 2000 and 2017) despite an increase in the frequency of POP-UI diagnosis in the same time frame.

CONCLUSION

The rate of concurrent surgery for patients with an early-stage gynecologic cancer and POP-UI-associated diagnosis in women older than age 65 years was 21.1%. Of women who did not undergo concurrent surgery but had a diagnosis of POP-UI, 1 in 18 underwent surgery for POP-UI within 5 years of their index cancer surgery. Dedicated efforts must be made to identify patients who would most benefit from concurrent cancer and POP-UI surgery in those with locoregional gynecologic cancers and pelvic floor disorders.

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.

Functional Changes of the Genitourinary and Gastrointestinal Systems before and after the Treatment of Endometrial Cancer-A Systematic Review

Simple Summary

Endometrial cancer is currently one of the most common gynecological cancer and accounts for around 5% of all female cancers. The treatment strategy most often includes surgery and adjuvant radiation therapy. Thanks to the high effectiveness of used treatment methods, the patients can live longer lives. Unfortunately their quality of life can be negatively affected by side effects resulting from weakening pelvic floor such as urinary incontinence, pelvic organ prolapse and fecal incontinence. In our paper we analyzed the studies published between 2010 and 2020 that touch upon the prevalence and management of pelvic floor dysfunction in endometrial cancer patients. Our results show increase in the incidence of pelvic floor disorders after various forms of endometrial cancer treatment and the need for more good quality research in the subject to be able to provide patients with holistic care focused on minimizing treatment side effects and prioritizing their quality of life.

Abstract

The incidence of endometrial cancer (EC), which coexists with such civilization diseases as diabetes, obesity or hypertension, is constantly increasing. Treatment includes surgery as well as brachytherapy, teletherapy, rarely chemotherapy or hormone therapy. Due to the good results of the treatment, the occurrence of side effects of therapy becomes a problem for the patients. One of the large groups of side effects includes the pelvic organ prolapse, urinary and fecal incontinence. The aim of this study was to present current knowledge on the occurrence of pelvic floor dysfunction in women treated for EC. A literature review was conducted in the PubMED and WoS databases, including articles on pelvic floor dysfunction in women with EC. PRISMA principles were followed in the research methodology. A total of 1361 publications were retrieved. Based on the inclusion and exclusion criteria, 24 papers were eligible for the review. Mostly retrospective studies based on different questionnaires were evaluated. No prospective studies were found in which, in addition to subjective assessment, clinical examination and objective assessment of urinary incontinence were used. Studies show a significant increase in the incidence of pelvic floor disorders, including urinary incontinence, after various forms of EC treatment. We believe that assessment of complications after endometrial cancer treatment is clinically relevant. The review emphasizes the importance of programming prospective studies to prevent and address these disorders at each stage of oncologic treatment.

Pelvic organ prolapse after 3 modes of hysterectomy: long-term follow-up

BACKGROUND

There are various indications and approaches for hysterectomy; yet, the difference in long-term risk of subsequent prolapse after surgery is not well studied.

OBJECTIVE

To assess the risk of prolapse after abdominal, vaginal, and laparoscopic or robotic hysterectomy for up to 17 years from surgery.

STUDY DESIGN

A retrospective chart review study of women undergoing hysterectomy across all indications (benign and malignant) between 2001 and 2008 was conducted. An equivalent random sample of hysterectomy patients was selected each year. We compared demographic and other surgical characteristics data including age, race, parity, body mass index, indication and year of hysterectomy, blood loss, cervix removal, cuff suspension, and complications using chi-square, Kruskal-Wallis test, and Fisher's exact across the 3 groups. Presence and treatment of subsequent prolapse (based on patient symptoms, pelvic exam, International Classification of Diseases, Ninth Revision diagnosis, and current procedural terminology pessary or surgical codes) were compared with Kaplan-Meier survival analysis and Cox proportional hazards regression.

RESULTS

Of the 2158 patients, 1459, 375, and 324 underwent open, vaginal, and laparoscopic or robotic hysterectomy, respectively. The vaginal group (56) was older than the abdominal (52) or laparoscopic or robotic (49) groups, with a P value of <.05. Most patients were White with a mean body mass index of 30 kg/m². The main indication was cancer for abdominal (33%) and laparoscopic or robotic hysterectomy (25%) and prolapse for vaginal hysterectomy (60%). Time to prolapse was shortest after vaginal surgery (27 months) and longest after laparoscopic or robotic surgery (71 months). After controlling for confounders, including surgery indication, the hazard ratio for subsequent prolapse was no different among vaginal (hazard ratio=1.36 [0.77-2.45]), laparoscopic or robotic (hazard ratio=1.47 [0.80-2.69]), or open (reference) hysterectomy. Prolapse grade was similar across the 3 groups. About 50% of women with recurrent prolapse received physical therapy, pessary, or surgical treatment.

CONCLUSION

At the 17-year follow-up, the route of hysterectomy is not associated with a difference in recurrence, grade, or subsequent treatment of prolapse when the indication for hysterectomy is considered. Prolapse, as an indication for hysterectomy, increases risk for recurrence. Women planning a hysterectomy should be counseled appropriately about the risk of subsequent prolapse.

Long-term quality of life outcomes of women treated for early-stage endometrial cancer

OBJECTIVE

To compare long-term quality of life in women treated for early-stage endometrial cancer with population norms, and to compare quality of life outcomes of patients who had total laparoscopic or total abdominal hysterectomy.

METHODS

Once the last enrolled patient had completed 4.5 years of follow-up after surgery, participants in the Laparoscopic Approach to Cancer of the Endometrium (LACE) clinical trial were asked to complete a self-administered questionnaire. Two instruments-EuroQol 5 Dimension 3-level (EQ-5D-3L) and the Functional Assessment of Cancer Treatment-General Population (FACT-GP)-were used to determine quality of life. The mean computed EQ-5D-3L index scores for LACE participants at different age categories were compared with Australian normative scores; and the FACT-GP scores were compared between patients treated with surgical treatments.

RESULTS

Of 760 women originally enrolled in the LACE trial, 259 (50.2%) of 516 women consented to provide long-term follow-up data at a median of 9 years (range 6-12) after surgery. On the EQ-5D-3L, long-term endometrial cancer survivors reported higher prevalence of anxiety/depression than normative levels across all age groups (55-64 years, 30% vs 14.9%; 65-74 years, 30.1% vs 15.8%; ≥75 years, 25.9% vs 10.7%). For women ≥75 years of age, the prevalence of impairment in mobility (57.6% vs 43.3%) and usual activities (58.8% vs 37.9%) was also higher than for population norms. For the FACT-GP, the physical (effect size: -0.28, p<0.028) and functional (effect size: -0.30, p<0.015) well-being sub-scale favored the total laparoscopic hysterectomy compared with total abdominal hysterectomy recipients.

CONCLUSION

Compared with population-based norms, long-term endometrial cancer survivors reported higher prevalence of anxiety/depression across all age groups, and deficits in mobility and usual activities for women aged ≥75 years. Physical and functional well-being were better among women who were treated with total laparoscopic hysterectomy than among those receiving total abdominal hysterectomy.
