Long-Term Complications of Office Hysteroscopy: Analysis of 1028 Cases

Implementation of Office Hysteroscopy for the Evaluation and Treatment of Intrauterine Pathology

Hysteroscopy provides a minimally invasive strategy to evaluate intrauterine pathology and manage conditions such as abnormal uterine bleeding, infertility, intrauterine adhesions, müllerian anomalies, and intrauterine foreign bodies. Increasing access to hysteroscopy procedures in the office has the potential to improve patient care by minimizing financial and logistical barriers, aiding in streamlined diagnosis and treatment planning, and potentially averting unnecessary operative procedures and anesthesia. Office hysteroscopy refers to procedures performed in outpatient settings where pain management involves no medications, oral nonsedating medications, local anesthetic agents, or oral or inhaled conscious sedation. We present best practices for the implementation of hysteroscopy in an office setting. These include appropriate patient selection, optimal procedural timing, cervical preparation for patients at highest risk of cervical stenosis or pain with dilation, individualized pain-management strategies, use of distension media, and video monitoring to engage patients in the procedure. We describe miniaturized equipment for use in the office setting and "no-touch" vaginoscopic approaches to limit patient discomfort. With appropriate training and experience, office hysteroscopy presents a simple and cost-effective modality for optimizing gynecologic care for our patients.

Uterine Fibroids and Infertility

Infertility is a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse. Uterine fibroids are the most common tumor in women, and their prevalence is high in patients with infertility. Fibroids may be the sole cause of infertility in 2–3% of women. Depending on their location in the uterus, fibroids have been implicated in recurrent pregnancy loss as well as infertility. Pregnancy and live birth rates appear to be low in women with submucosal fibroids; their resection has been shown to improve pregnancy rates. In contrast, subserosal fibroids do not affect fertility outcomes and their removal does not confer any benefit. Intramural fibroids appear to reduce fertility, but recommendations concerning their treatment remain unclear. Myomectomy should be discussed individually with the patient; other potential symptoms such as dysmenorrhea or bleeding disorders should be included in the indication for surgery.

Oral Desogestrel as Endometrial Preparation before Operative Hysteroscopy: A Systematic Review

The pharmacologic preparation of the endometrium before hysteroscopy may be achieved with the use of various drugs. This systematic review aims to summarize the available evidence regarding the use of desogestrel for endometrial preparation before hysteroscopic procedures. A literature search for suitable articles published in English language from inception of the database until August 2019 was performed using the following databases: PubMed/MEDLINE, EMBASE, the Cochrane Library, and Google Scholar. All original articles concerning desogestrel-only pretreatment before hysteroscopic surgery were considered eligible. Reviews, case reports/series, conference papers, studies including the use of combined hormonal preparation, and articles in languages other than English were excluded from the analysis. The literature search retrieved 3 studies that met all the inclusion criteria. The data demonstrated that desogestrel may be considered as a hormonal pretreatment drug before hysteroscopic procedures. The drug was distinctly effective and assessed as helpful by the operating surgeon in numerous patients who were administered the pretreatment of 75 μg daily. Oral desogestrel is a cheap, easily available, safe, and quite efficient alternative for endometrial preparation before hysteroscopic procedures.

Four year evaluation of therapeutic hysteroscopy under procedural sedation in an outpatient clinic

OBJECTIVE

Due to the evolution of hysteroscopic instruments, therapeutic hysteroscopic procedures are increasingly performed in an outpatient, office-based setting. The most important limiting factor of performing these hysteroscopic treatments is patient discomfort. Procedural Sedation Analgesia (PSA) decreases patient discomfort and anxiety. The main goal of this study is to determine safety, feasibility and patient satisfaction of therapeutic hysteroscopy performed under procedural sedation in an outpatient clinic. Our second objective was to compare 9 mm scopes with smaller diameter scopes.

STUDY DESIGN

All consecutive patients suitable for procedural sedation and scheduled for a therapeutic hysteroscopy in the outpatient clinic were prospectively included from February 2014 to November 2018 in a teaching hospital in the Netherlands. A variety of therapeutic hysteroscopies procedures was performed including myomectomy, removal of retained products of conception and endometrial ablation. Therapeutic hysteroscopes with 3.8 mm, 5 mm and 9 mm diameter were used. In all selected women procedure time, admission time, pain scores, anaesthesiologic and procedural complications were assessed. All women received a questionnaire on patient satisfaction.

RESULTS

In total 455 patients underwent a therapeutic hysteroscopy. Median procedure time was 11 min (2-63 min) and median admission time was 130 min (30-480 min). Median pain score according to the visual analog scale (VAS) before, during and after procedure were respectively 0 (0-10), 0 (0-4) and 0 (0-9). Anaesthesiologic complication rate was 4.4 %, all minor. Procedural complications consisted of infection postoperatively (0.4 %), excessive blood loss during procedure (0.6 %) and perforation (0.4 %). Procedure was incomplete in 3.3 % of all procedures. Patient satisfaction was high, as 96 % of the women were satisfied. No differences were found in pain scores, VAS 0 versus 1 after the procedure, between 3.8 or 5 mm and 9 mm scopes.

CONCLUSION

It is safe and feasible to perform a therapeutic hysteroscopy under procedural sedation in an outpatient setting, with low pain scores and a high degree of patient satisfaction, also when large diameter instruments are used.

Comparison between Different Diagnostic Strategies in Low-Risk Reproductive Age and Pre-Menopausal Women Presenting Abnormal Uterine Bleeding

Abnormal uterine bleeding (AUB) is a common symptom in the female population, with an estimated prevalence of 10 to 30% in fertile age and up to 90% in perimenopausal women. In most cases, AUB is due to a benign cause. However, it can also be a symptom of atypical endometrial hyperplasia or endometrial cancer, a more common disease during menopause which can also affect women in their reproductive age. Considering the high prevalence of this symptom an appropriate diagnostic algorithm is needed. Concerns about the risks, pain, and stress associated with an endometrial biopsy and its impact on the healthcare system make the choice of AUB diagnostic strategy extremely relevant. Even if the scientific community agrees on the definition of AUB, International Guidelines show some differences in the management of women of reproductive age with AUB, especially regarding the age cut-off as an independent indication for endometrial biopsy. This study compared different diagnostic strategies to identify a diagnostic pathway with high sensitivity and specificity but low impact on the health system's resources. The analysis was based on three diagnostic algorithms defined as part of the guidelines of leading scientific societies. Women of reproductive age with AUB (n = 625) and without risk of endometrial cancer were included in the study. Results showed that the best criterion to investigate AUB in women at low risk of endometrial cancer is not age cut-off but the presence or absence of focal endometrial pathology at the ultrasound and the response to the progestin therapy. This approach makes it possible to perform fewer outpatient hysteroscopic biopsies without excluding positive cases from the examination.

Management of anxiety and pain perception in women undergoing office hysteroscopy: a systematic review

PURPOSE

The aim of this review is to provide an overview of the literature about the perception and management of anxiety and pain in women undergoing an office hysteroscopic procedure.

METHODS

We performed a systematic literature search in Embase, PubMed/MEDLINE, Cochrane Library and Web of Science for original studies written in English (registered in PROSPERO 2019-CRD42019132341), using the terms 'hysteroscopy' AND 'pain' AND 'anxiety' published up to January 2019. Only original articles (randomized, observational and retrospective studies) about management of anxiety and pain related to the hysteroscopic procedure were considered eligible.

RESULTS

Our literature search produced 84 records. After exclusions, 11 studies including 2222 patients showed the following results: (a) pain experienced during hysteroscopy is negatively affected by preprocedural anxiety; (b) pharmacological interventions seem to be help in reducing pain during hysteroscopy; (c) waiting time before the procedure is a significant factor affecting patients' anxiety; (d) music during the procedure may be helpful in reducing anxiety.

CONCLUSIONS

The utilization of office hysteroscopy is hampered by varying levels of anxiety and pain perceived by women who are candidates for the procedure. For these reasons, it is essential to identify effective pharmacological and non-pharmacological strategies to alleviate these factors. We recommend further studies especially focusing on non-pharmacological interventions to facilitate the dissemination of good clinical practices among hysteroscopists.

Effectiveness of Hysteroscopic Techniques for Endometrial Polyp Removal: The Italian Multicenter Trial

STUDY OBJECTIVE

To compare the effectiveness and safety of different techniques of hysteroscopic polypectomy.

DESIGN

Multicenter, prospective observational trial (Canadian Task Force classification II-2).

SETTING

Nineteen Italian gynecologic departments (university-affiliated or public hospitals).

PATIENTS

Consecutive patients suffering from endometrial polyps (EPs).

INTERVENTIONS

Hysteroscopic polypectomy, as performed through different techniques.

MEASUREMENTS AND MAIN RESULTS

Included in the study were 1404 patients (with 1825 EPs). The setting was an ambulatory care unit in 40.38% of the cases (567 women), of whom 97.7% (554) did not require analgesia/anesthesia. In the remaining 59.62% of women (837 women), the procedures were performed in an operating room under mild sedation, local or general anesthesia. Minor complications occurred in 32 patients (2.27%), without significant differences between the techniques used (p = ns). Uterine perforation occurred in 14 cases, all performed in the operating room with some kind of anesthesia, only 1 with a vaginoscopic technique and the remaining during blind dilatation (odds ratio [OR], 19.98; 95% confidence interval [CI], 1.19-335.79; p = .04). An incomplete removal of EPs was documented in 39 patients. Logistic regression analysis showed that a higher risk of residual EPs was associated with the use of a fiber-based 3.5-mm hysteroscope (OR, 6.78; 95% CI, 2.97-15.52; p <.001), the outpatient setting (OR, 2.17; 95% CI, 1.14-4.14; p = .019), and EPs located at the tubal corner (OR, 1.98; 95% CI, 1.03-2.79; p = .039). No association between incomplete EP removal and EP size or number was recorded (p = ns), as well as with the other variables evaluated.

CONCLUSION

Outpatient polypectomy was associated with a minimal but significantly higher risk of residual EPs in comparison with inpatient polypectomy. Conversely, inpatient polypectomy was associated with a considerably higher risk of uterine perforation and penetration in comparison with office hysteroscopy. Because of lower intraoperative risks and higher cost-effectiveness, office hysteroscopy may be considered, whenever possible, as the gold standard technique for removing EPs.

A Pilot Study Comparing Hysteroscopic Adhesiolysis by Conventional Resectoscope Versus Mini-resectoscope

OBJECTIVES

To compare the feasibility and efficacy of the mini-resectoscope with the conventional resectoscope in terms of the operative, menstrual, and reproductive outcome in hysteroscopic adhesiolysis in infertile women.

METHODS

We conducted a parallel prospective randomized study at All India Institute of Medical Sciences, New Delhi. A total of 60 patients underwent hysteroscopic adhesiolysis using either conventional resectoscope (n = 30) or mini-resectoscope (n = 30). The primary outcome measures were pregnancy-related indicators. Secondary outcome measures were the operative parameters (cervical dilatation time, operation time, postoperative pain scores, fluid deficit, and preoperative and postoperative sodium levels), second-look hysteroscopy findings, and improvement in the menstrual pattern after surgery.

RESULTS

Cervical dilatation time and pain score 30 minutes after the procedure were significantly lower in the mini-resectoscope group. Out of the total 21 cases with hypomenorrhea, 12 cases (57.1%) started having normal menstrual flow postsurgery. All amenorrheic patients resumed menstruation after surgery. However, nine cases continued to have hypomenorrhea. Over long-term follow-up, 16 patients out of 60 had conceived (seven in the conventional resectoscope group and nine in the mini-resectoscope group). There were three ongoing pregnancies, three abortions, one ectopic pregnancy, and nine term pregnancies. The difference between the two groups was not statistically significant.

CONCLUSIONS

The use of mini-resectoscope for hysteroscopic adhesiolysis is associated with reduced operative morbidity. Use of the mini-resectoscope is an effective and safe alternative to the conventional system.

Hysteroscopy: guidelines for clinical practice from the French College of Gynaecologists and Obstetricians

The objective of this study was to provide guidelines for clinical practice from the French College of Obstetrics and Gynecology (CNGOF), based on the best evidence available, concerning hysteroscopy. Vaginoscopy should be the standard technique for diagnostic hysteroscopy (Grade A) using a miniature (≤3.5mm sheath) (Grade A) rigid hysteroscope (Grade C), using normal saline solution distension medium (Grade C), without any anaesthesia (conscious sedation should not be routinely used), without cervical preparation (Grade B), without vaginal disinfection and without antibiotic prophylaxy (Grade B). Misoprostol (Grade A), vaginal oestrogens (Grade C), or GnRH agonist routine administration is not recommended before operative hysteroscopy. Before performing hysteroscopy, it is important to purge the air out of the system (Grade A). The uterine cavity distention pressure should be maintained below the mean arterial pressure and below 120mm Hg. The maximum fluid deficit of 2000ml is suggested when using normal saline solution and 1000ml is suggested when using hypotonic solution. When uterine perforation is recognized during operative hysteroscopy using monopolar or bipolar loop, the procedure should be stopped and a laparoscopy should be performed in order to eliminate a bowel injury. Diagnostic or operative hysteroscopy is allowed when an endometrial cancer is suspected (Grade B). Implementation of this guideline should decrease the prevalence of complications related to hysteroscopy.

Experience and results of office hysteroscopy at a primary hospital

Our aim was to analyse, retrospectively, the perioperative outcomes of 3,488 office hysteroscopies. Age, menopausal status, parity, medical indications, use or not of anaesthesia, incidents, presence of pathology in the cavity, endometrial pathology, type of surgery and pain assessment details were collected. The mean age of patients was 52.1 years. The most common medical indication was suspicious ultrasound for endometrial disease, and the most frequent symptom was metrorrhagia. We did not use any type of anaesthesia in 89.5% of patients and we could access the uterine cavity in 99.4% of cases. The complication rate was very low though 12% of patients reported severe pain while performing the test. Although office hysteroscopy in outpatients is fully established and is usually well tolerated, there is a group of patients who could benefit from analgesic treatment prior to the test, to improve their tolerance.

[Prevention of the complications related to hysteroscopy: guidelines for clinical practice]

OBJECTIVE

To provide clinical practice guidelines (CPGs) from the French college of obstetrics and gynecology (CNGOF), based on the best evidence available, concerning the adverse events related to hysteroscopy.

MATERIALS AND METHODS

Review of literature using following Keywords: hysteroscopy; vaginoscopy; infection; perforation; intrauterine adhesions

RESULTS

Vaginoscopy should be the standard technique for outpatient hysteroscopy (grade A) using a miniature (≤ 3.5mm sheath) (grade A) rigid hysteroscope (grade C), using normal saline solution distension medium (grade C), without any anesthesia (conscious sedation should not be routinely used), without cervical preparation (grade B), without vaginal disinfection and without antibiotic prophylaxy (grade B). Misoprostol (grade A), vaginal estrogens (grade C), or GnRH agonist routine administration is not recommended before operative hysteroscopy. Before performing hysteroscopy, it is important to purge the air out of the system (grade A). The uterine cavity distention pressure should be maintained below the mean arterial pressure and below 120 mmHg. The maximum fluid deficit of 2000 mL is suggested when using normal saline solution and 1000 mL is suggested when using hypotonic solution. When uterine perforation is recognized during operative hysteroscopy using monopolar or bipolar loop, the procedure should be stopped and a laparoscopy should be performed in order to eliminate a bowel injury. Diagnostic or operative hysteroscopy is allowed when an endometrial cancer is suspected (grade B).

CONCLUSION

Implementation of this guideline should decrease the prevalence of complications related to office and operative hysteroscopy.
