Effects of vaginal dilation therapy on vaginal condition and sexual function of endometrial cancer patients treated with radiotherapy after surgery

OBJECTIVE

This study aimed to evaluate the effect of vaginal dilation therapy on vaginal length, vaginal stenosis, vaginal elasticity, and sexual function of endometrial cancer patients treated with radiotherapy after surgery.

METHODS

A total of 117 women were enrolled in this study. They received 6 months of vaginal dilation therapy. We evaluated their vaginal length, vaginal diameter, vaginal elasticity, and sexual function before radiotherapy, after radiotherapy, and after 6 months of vaginal dilation therapy. Their vaginal condition was assessed by customized vaginal dilating molds. Their sexual function was assessed by female sexual function index. The SPSS 25 software was used to analyze all the data.

RESULTS

According to multivariate analysis, vaginal diameter (β = 0.300, 95% CI [0.217-1.446], p = 0.010) and sexual intercourse frequency before diagnosis (β = 0.424, 95% CI [0.164-0.733], p = 0.006) were significantly correlated with female sexual function after radiotherapy. Vaginal dilation therapy helped increase vaginal length, improve vaginal stenosis and sexual function (p < 0.05), though most of the figures at the end of the intervention did not fully return to those before radiotherapy. Noticeably, vaginal dilation therapy was ineffective in improving vaginal elasticity and the incidence rate of female sexual dysfunction (p > 0.05). Moreover, patients with medium or good vaginal elasticity benefited more from vaginal dilation therapy than patients with poor vaginal elasticity (p < 0.05).

CONCLUSION

Vaginal dilation therapy should be carried out timely and preventatively in endometrial cancer patients treated with radiotherapy after surgery to improve their vaginal condition and sexual function.

Vaginal stenosis treatment using computed tomography and fluoroscopy guidance

INTRODUCTION

Vaginal stenosis is a common complication following construction of a neovagina with vascularized myocutaneous flaps. This is primarily because of inconsistent or inappropriate vaginal dilator use. Image-guided recanalization, especially for obstructed genitourinary tracts, is an emerging idea in interventional radiology. Although multiple surgical techniques have been reported to treat vaginal agenesis or obstruction, the idea of image-guided recanalization of vaginal stenosis is a relatively new management strategy for vaginal stenosis.

CASE

We present a challenging case of a patient who initially presented with the complaint of increasing pelvic pressure after the creation of a neovagina via vaginoplasty. She had a distal neovagina created after extensive surgical resection for a large infiltrating pelvic rectal adenocarcinoma. A computed tomography scan revealed a fluid-filled neovaginal abscess. Examination under anesthesia revealed complete stenosis of the neovagina with no identifiable tract for dilation.

INTERVENTION

A computed tomography scan and fluoroscopy-guided sharp recanalization of the stenosed neovagina was performed, followed by serial fluoroscopic balloon angioplasty to dilate the stenosed neovagina. Finally, the patient underwent a gynecologic surgery for the excision of remaining granulation tissue to produce a more permanent patent neovagina, followed by regular and proper use of vaginal dilators to ensure patency.

CONCLUSION

This case report demonstrates that image-guided techniques can be used to aid in vaginal recanalization in the postoperative setting.

Sexual Health Update in Women

The Clinical Update series is intended to help busy clinicians stay up to date with recently published important and potentially practice-changing articles on topics pertinent to the care of women. In this update on sexual health, we review studies on use of vaginal dilators for vaginal stenosis in gynecologic cancer survivors, sexual dysfunction in transgender people, as well as studies evaluating the effect of physical activity and infertility on female sexual health.

Conception following successful repair of two previous failed attempts at repair of partial transverse vaginal septum diagnosed after marital union: A case report

Transverse vaginal septum is a congenital anomaly in which a membrane obstructs the vagina. This can be partial or complete in type. Although rare, it presents peculiar challenges in symptomatology, diagnosis, and ultimate management. To our knowledge, we are the first to report a shortest vaginoplasty-conception interval following successful repair of previously failed repair of partial transverse vaginal septum. A 28-year-old Nigerian married nulliparous lady who presented to us with history of inability of penile-vaginal penetration with the presence of normal menstrual flow after two previous failed attempts at repair. She had a vaginoplasty with placement of a vaginal mold to prevent stenosis. She was subsequently able to have successful sexual intercourse and achieved pregnancy after 2 months, without recurrence of vaginal stenosis. When transverse vaginal septum is encountered in a married nullipara, a thorough clinical evaluation of the viability and feasibility of a vaginoplasty should be made during the first surgery. If repeated failed repair occurs, as in our case, we recommend meticulous and experienced surgical attention from the outset. The originality in this report lies in the very short period between repair and successful conception. Thus, we obtained satisfactory short-term clinical outcome of successful conception at the 2 months follow-up.

Using New Vaginal Doses Evaluation System to Assess the Dose-Effect Relationship for Vaginal Stenosis After Definitive Radio(Chemo)Therapy for Cervical Cancer

Objective

The study aims to investigate if a relationship exists between vaginal doses and vaginal stenosis (VS) using posterior-inferior border of symphysis (PIBS) points and the International Commission on Radiation Units-Rectum (ICRU-R) point evaluation system for definitive radio(chemo)therapy in locally advanced cervical cancer.

Methods and Materials

From a vaginal dose study in China, 351 patients were prospectively assessed. For every reference point of the PIBS system and ICRU-R point was calculated for all BT and summed with EBRT. Pearson's chi-square test and Student's unpaired t-test compared variables with and without vaginal stenosis (VS) G ≥2. The risk factors were assessed for VS G ≥2 in multi- and univariate analyses through Cox proportional hazards model followed by a dose-effect curve construction. The VS morbidity rate was compared via the log-rank test using the median vaginal reference length (VRL).

Results

The patients (38-month median follow-up) had 21.3% three-year actuarial estimate for VS G ≥2. Compared to G <2 patients, VS G ≥2 patients received higher doses to PIBS points except for PIBS - 2 and had significantly shorter VRL. VRL (HR = 1.765, P = 0.038), total EBRT and BT ICRU-R point dose (HR = 1.017, p = 0.003) were risk factors for VS. With VRL >4.6 cm, the 3-year actuarial estimate was 12.8% vs. 29.6% for VRL ≤4.6 cm. According to the model curve, the risks were 21, 30, and 39% at 75, 85, and 95 Gy, respectively (ICRU-R point dose).

Conclusions

PIBS system point doses correlated with late vaginal toxicity. VRL combined with both EBRT and BT dose to the ICRU-R point contribute to VS risk.

Vaginal dilator use to promote sexual wellbeing after radiotherapy in gynecological cancer survivors

This study investigated the efficacy of a vaginal dilator (VD) for the treatment of radiation-induced vaginal stenosis (VS) and the effect of a VD on sexual quality of life.Fifty three patients with endometrial or cervical cancers participated in this prospective observational study. All participants were treated with radical or adjuvant external beam radiotherapy and/or brachytherapy. They were routinely examined 4 times after radiotherapy (RT) and were also asked to complete a validated sexual function-vaginal changes questionnaire. SPSS version 20 and Minitab version 16 were used for the statistical analysis. The statistical significance was set at P < .05.The VS grading score decreased and the comfortably insertable VD size gradually increased throughout a year of VD use; all patients with initial grade 3 showed a VS of grade 2 after 12 months of VD use and 65.8% of the patients with initial grade 2 demonstrated a final VS of grade 1, while 77.8% of the participants who started with the first size of VD reached the third size after 12 months. Starting VD therapy ≤3 months after the end of RT was associated with a significant decrease in VS. A total of 60.9% of participants reported that they did not feel their vaginas were too small during intercourse after 12 months of dilation, whereas only 11.5% gave the same answer before starting dilation. Furthermore, 47.17% rated their satisfaction with their sexual life 5 out of 7 and only 3.77% gave a score of 3 after 12 months of dilation.Endometrial and cervical cancer survivors are encouraged to use VD to treat VS and for sexual rehabilitation after RT. This study recommends starting vaginal dilation no more than 3 months after treatment at least 2 to 3 times a week for 10 to 15 minutes over 12 months. However, larger, well-designed randomized clinical trials should be conducted to develop specific guidelines for VD use and efficacy in VS and sexual sexual quality of life after RT.

Sexual Dysfunction in Cervical Cancer Survivors: A Scoping Review

Sexual function in cervical cancer survivors declines significantly after treatments irrespective of the modality used. Only a few studies have looked at their psychosexual needs, perception, and acceptance of psychosexual support. This review summarizes findings of current qualitative as well as quantitative studies to understand the plight of cervical cancer survivors regarding sexual dysfunction and the management issues. The effect of gynecologic cancers on sexuality depends on multiple factors such as psychosexual factors, biologic factors, and age. Younger patients have poorer outcomes with a more pronounced impact on sexual well-being. Radicality of surgery has direct correlation with sexual dysfunction. Low or no sexual interest, lack of lubrication, dyspareunia, and reduced vaginal caliber are frequently found. For too long, researchers have focused on defining the prevalence and types of sexual problems after various cancer treatments. The area that continues to be neglected is the evaluation of effective interventions to prevent or treat cancer-related sexual dysfunction. In particular, mental health and medical specialists need to collaborate to create cost-effective treatment programs. Collaborative intervention with gynecologists, sexologists, radiotherapists, and nursing staff would be beneficial to optimize the sexual wellness of cancer survivors and their spouses.

Pelvic Radiation Therapy Induced Vaginal Stenosis: A Review of Current Modalities and Recent Treatment Advances

Radiation-induced vaginal stenosis (VS) is a common side effect of pelvic radiotherapy (RT). RT-induced VS may have various negative effects on women’s quality of life, in particular dyspareunia, decreased vaginal lubrication and difficulties in sexual intercourse. This narrative review provides the aspects of RT-induced VS pathogenesis, incidence, evaluation and associated risk factors. Available treatment modalities are discussed in the article, putting the focus on preliminary, although promising, experience in the use of hyaluronic acid and laser therapy in cancer survivors after pelvic RT.

The first major complication due to laser treatment for stress urinary incontinence: a short report

AIM

Stress urinary incontinence (SUI) is a common benign disease causing a markedly negative impact on quality of life. Vaginal laser is a minimally invasive treatment and no major complications of this technique have been published to date. The purpose of the article is to present the first major adverse event related to this treatment.

MATERIALS AND METHODS

We present the case of a 48-year-old woman with an important complication after vaginal laser for SUI.

RESULTS

The patient presented a transverse vaginal septum and shortening of vaginal length after two sessions of vaginal erbium:yttrium aluminum garnet laser treatment. She required two surgical interventions, local injections, and pelvic floor physiotherapy, although currently the patient has not experienced complete resolution of symptoms.

DISCUSSION AND CONCLUSIONS

Vaginal laser use can lead to serious adverse events. Selection of patients and treatment must be carried out with caution.

EROS study: evaluation between high-dose-rate and low-dose-rate vaginal interventional radiotherapy (brachytherapy) in terms of overall survival and rate of stenosis

Purpose

To compare the survival and toxicity outcomes in patients with endometrial cancer treated with either high-dose-rate (HDR) or low-dose-rate (LDR) vaginal brachytherapy (VBT) following external beam radiotherapy (EBRT).

Material and methods

From January 2000 to December 2014, patients with endometrial cancer after radical hysterectomy with/without pelvic and/or para-aortic lymphadenectomy were treated with adjuvant EBRT (45 Gy, 1.8 Gy/day to the whole pelvis) and subsequent VBT boost (HDR dose of 7 Gy in one fraction or LDR VBT dose of 25 Gy). The dose was prescribed at 0.5 cm from the surface of the applicator and the proximal half to two-thirds of the vagina was irradiated. The outcomes of patients were evaluated in terms of local control (LC), overall survival (OS), and rates of adverse events.

Results

We analyzed data of 200 patients treated with EBRT followed by HDR VBT boost in 78 patients and LDR VBT boost in 122 patients. With a median follow-up of 25 months (range, 6-163), 5-year OS was 98% and 97% in the LDR and HDR groups, respectively (p = 0.37). The 5-year LC was similar (93% in both groups) (p = 0.81). In multivariate analyses, none of the factors assessed (age, stage, grade) impacted OS (p = 0.37) or LC (p = 0.81). Patients treated with LDR VBT after EBRT had higher rates of acute gastrointestinal toxicity. No differences were found in acute genitourinary or hematological toxicities. Late toxicity such as vaginal stenosis was registered during regular follow-up visits and was similar in the two groups (p = 0.67).

Conclusions

In our analysis, there were no differences in terms of OS and late toxicity outcomes for patients receiving LDR or HDR VBT. HDR VBT is a safe technique in comparison to LDR VBT.

Radiation-induced vaginal stenosis: current perspectives

Treatment of gynecological cancer commonly involves pelvic radiation therapy (RT) and/or brachytherapy. A commonly observed side effect of such treatment is radiation-induced vaginal stenosis (VS). This review analyzed the incidence, pathogenesis, clinical manifestation(s) and assessment and grading of radiation-induced VS. In addition, risk factors, prevention and treatment options and follow-up schedules are also discussed. The limited available literature on many of these aspects suggests that additional studies are required to more precisely determine the best management strategy of this prevalent group after RT.

Case of early postoperative adhesion in a patient with molimina due to transverse vaginal septum concomitant with imperforate hymen

Transverse vaginal septum is a residual vaginal plate composed of the Müllerian duct and urogenital sinus. Imperforate hymen results from failure of perforation of the membrane between the urogenital sinus and vaginal cavity. We report a rare case of concurrence of these two conditions. A 16-year-old girl had been treated with puncture several times for hematometra and hematocolpos from 13 years of age because of monthly occurrence of lower abdominal pain without menstrual bleeding and was referred to our hospital. Magnetic resonance imaging demonstrated hematometra, hematocolpos and expansion of the vaginal fornix. The imperforate hymen was incised and a slight adhesion at the lower vaginal cavity was detached. After that, a complete transverse vaginal septum, which was 5 mm thick, was identified. It was excised after ultrasonography-guided puncture. Although two cycles of menstrual bleeding took place, molimina recurred. Re-operation was performed 6 months after the first operation, and recurrence of adhesion in the lower vaginal cavity was identified. A silicon dilator was inserted, but she could not use it at home and instead used a tampon. Cyclic menstrual bleeding is observed 4 months after the second operation.

Simultaneous bladder and vaginal reconstruction using ileum in complicated vesicovaginal fistula

OBJECTIVES

To discuss the outcome of surgical repair in complicated vesicovaginal fistula with simultaneous bladder and vaginal reconstruction using ileum.

MATERIALS AND METHODS

Four female patients in the age group of 12-30 years are included. All the patients had complicated vesicovaginal fistula with vaginal stenosis secondary to obstetric hysterectomy (except one secondary to the genitourinary tuberculosis). Repair of vesicovaginal fistula with simultaneous bladder augmentation, ureteric reimplantation, and reconstruction of vagina using ileum was performed in all the cases.

RESULTS

All the patients had successful repair of fistula. Vaginal reconstruction using ileum, resulted in capacious vagina. Adult patients resumed to normal sexual life. Mucus discharge was the only complaint in postoperative period.

CONCLUSIONS

Malnutrition, anemia, obstructed labor, Intra uterine fetal death (IUFD), postpartum hemorrhage following forceps delivery in a rural setting followed by an emergency obstetric hysterectomy after a delay of 6-8 h (due to transfer to a tertiary center) were the few contributing factors leading to the formation of vesicovaginal fistula (VVF). Preoperative assessment of bladder capacity and vaginal capacity in such cases is mandatory. The small bowel is a readily available vascular tissue for restoring bladder and vaginal capacity.
