Abstract:

Objective: To compare 3D Gel installation sonohysterography (3D GIS) with office hysteroscopy (OH) in assessment of uterine cavity prior to ICSI procedure in patients with reproductive failure

Patients and Methods: 180 women with reproductive failure (infertility or repeated pregnancy losses) planned for ICSI procedure were recruited from those attendants of outpatient infertility clinic of obstetrics and gynecology department of Qena and Al-Azhar University Hospitals during the period from January 2016 to December 2016. Uterine cavity assessment was done by 3D Gel installation sonohysterography and office hysteroscopy in the postmenstrual proliferative phase of menstrual cycle. Sensitivity and specificity, positive and negative predictive values of 3D Gel instillation sonohysterography were assessed.

Results: 27 cases (15%) had abnormal uterine cavity or intrauterine lesions and 153 cases (85%) reported as normal by 3 D GIS (sensitivity of 88.9%, specificity 98%, positive predictive value of 88.9% and negative predictive value 98%).

Conclusions: 3D GIS had good predictive values in detection of uterine cavity anomalies and intrauterine lesions in comparison to hysteroscopy.

Recommendations: 3D GIS can be an alternative to office hysteroscopy in uterine cavity assessment prior to ICSI procedure.

1. Introduction


In fact, infertility related to uterine cavity abnormalities has been estimated to be the causal factor in as many as 10% to 15% of couples seeking treatment. Moreover, abnormal uterine findings have been found in 34% to 62% of infertile women [1]. A successful pregnancy outcome for infertile women undergoing ICSI procedure depends on many factors. Among these factors good embryo quality (A or B), favorable intrauterine environment and a skillful ICSI laboratory are prerequisites to achieve a successful pregnancy outcome. Intrauterine abnormalities play an important role in implantation failure in ICSI trials [2-4].

Different methods such as hysterosalpingography (HSG), transvaginal sonography (TVS), three dimensional transvaginal sonography (3-D TVS), three dimensional saline infusion sonography (3-D SIS) and diagnostic hysteroscopy, can be used in uterine abnormalities diagnosis. Hysteroscopy has been established as gold standard in infertility work up with high accuracy in diagnosis [3,5,6]. The availability of office hysteroscopy nowadays has been used for outpatients as a routine examination. It allows direct visualization of the uterine cavity and detects any uterine cavity abnormalities as biconuate uterus, uniconuate or uterine septum, also can detect the presence of intrauterine lesions or pathologies such as polyps, submucous fibroids or adhesions [7].

Recently transvaginal 3D ultrasonography is considered as accurate and noninvasive tool for uterine cavity assessment in outpatients so it can take place. Office hysteroscopy (OH) costs less in comparison to hysteroscopy with no complications [9,10]. Instillation sonography was introduced to improve the reliability of transvaginal ultrasound and, in the meantime, make advantage of its relative easiness compared to Diagnostic Hysteroscopy [11]. Sonohysterography is a procedure in which fluid (saline or gel) is instilled transcervically into the uterine cavity to provide enhanced visualization of the endometrial lining during transvaginal ultrasound examination. Both saline infusion sonohysterography and Gel Infusion sonohysterography are simple, safe, well tolerated and accurate techniques in the assessment of intra-uterine abnormalities [12]. As water easily leaks from the body cavity, it has to be replenished continuously during imaging, gel rather than watery contrast is used for GIS, which is a simple technique offering an optimal and stable distension of the uterine cavity with minimal inconvenience for the patient [15].


2. Objective


The aim of this study was to evaluate 3D GIS vs. OH in uterine cavity assessment prior to ICSI procedure in patients with reproductive failure.

Patients and Methods: 180 women with reproductive failure planned for ICSI procedure were recruited in this study from those attendants of outpatient infertility clinic of obstetrics and gynecology department of Qena and Al – Azhar University Hospitals during the period from January 2016 to December 2016. Exclusion criteria was acute or chronic PID, possible pregnancy, cervical stenosis, active uterine bleeding, uterine size >12 cm).

A written consent was obtained from all participants and the study was approved from Medical Ethics Committee of Faculty of Medicine, South Valley and Al- Azhar Universities.


3. Methods


1. Thorough history was taken, general and local examination was done for all participants in this study.

2. For all participants uterine cavity was assessedby3DGelinstillation sonohysterography and office hysteroscopy in the postmenstrual proliferative phase of menstrual cycle 3 or 4 days apart by 2 different operators and the findings were recorded separately. Prophylactically broad spectrum antibiotic was given to all patients to minimize intrauterine infection also intravenous or intramuscular potent analgesia was given before procedure for all patients to abolish uterine distention pain of GIS or OH.


4. Technique


After inspection of the uterine cervix with the use of a Cusco's speculum, a neonatal suction tube was used for Gel Instillation connected to the syringe with gel, the use of a tenaculum for gentle cervical traction was necessary. After removal of the speculum, the 3D ultrasound transducer was introduced into the vagina and the uterus was determined in the longitudinal plane figure (1).




Approximately 20 ml of EX -EM gel was instilled into the uterine cavity by pushing the plunger of the syringe with light pressure by an assistant. After detection the gel foam in the uterine cavity in the sagittal plane, the transducer was rotated to the cross sectional plane to visualize uterine cavity in coronal section for better assessment. Uterine cavity contour was inspected for irregularities and suspected intracavitary lesions. Deformations of the endometrial lining, absence of central hyperechoic line, and the appearance of any structure with or without well-defined margins or variable echogenicity were considered abnormal figure (2, 3, and 4).


     

Office hysteroscopy was performed with a rigid micro- hysteroscope (storz trade) with a 2.9 mm diagnostic sheath. Normal saline solution was used as distention medium with maximum intrauterine pressure of 100 mm Hg. The uterine cavity was evaluated with inspection of both tubal ostia. Cervical preparation was done using 200 ug of misoprostol 6 hours prior to office hysteroscopy to minimize introduction failure rate. Vaginoscopy was the main trend used for office hysteroscopy. Assessment of anterior, posterior and lateral walls of uterine cavity was carefully done and any intrauterine abnormalities as uterine septum or intrauterine lesions as polyps, adhesions and sub mucous fibroids were recorded. During both procedures the patients were asked to rate the pain experienced using a 100-mm visual analog scale (VAS).

Sensitivity, specificity, positive and negative predictive values of 3D GIS in detection of uterine anomalies or intra cavitery lesions were assessed and data interpreted and statistically analyzed.


5. Statistical Methods


Results were expressed as means ± standard deviation (SD) or number (%). Comparison between categorical data was performed using Chi square test. Standard diagnostic indices including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy were calculated as described by Galen (1980). The data were considered significant if p-values was ≤ 0.05 and highly significant if p< 0.01. Statistical analysis was performed with the aid of the SPSS computer program (version 19 windows).


6. Results


27 of 180 cases had abnormal uterine cavity or intrauterine lesions that represents (15%) and 153 (85%) cases reported as normal by 3 D GIS, with office hysteroscopy only 24 of 27 of abnormal 3 D GIS cases confirmed as abnormal (true positive) and 3 cases were normal (false positive) and 150 of 153 of 3 D GIS normal cases were normal by office hysteroscopy (true negative and 3 cases were abnormal (false negative).

Table 1 shows characteristics of the studied patients

Table 2 and 3 show comparison between the two procedures as regard to pain and complications respectively. Pain, bleeding and headache were significantly higher after OH.


7. Discussion


Uterine factor represents only 2 to 3% of female infertility, but intrauterine lesions are more common in this condition (40–50%). These lesions can affect the natural fertility beside affect pregnancy rates [21,22]. Acquired uterine lesions, such as uterine fibroids, endometrial polyps, intrauterine adhesions, or all of these, may cause infertility by interfering with proper embryo implantation and growth [3]. Gel instillation can be used as an alternative for saline infusion during sonohysterography. The technique is easy to learn and seems attractive as a first choice because the technique is convenient for both the patient and the ultrasonographer. GIS offers a more stable filling of the uterine cavity, which allows detailed examination with a very precise visualization of the uterine cavity and its linings. The use of gel for this purpose is not entirely new; a dextran 70 solution was described in 1987 in first study on ultrasound and uterine cavity distension[23].

In our study, 180 patients with suspected uterine factor of infertility or a cause for recurrent pregnancy wastage were included. Patients suffered from 1ry infertility were 60.5%, 31.7% had 2ry infertility and 7.8% suffered from recurrent pregnancy loss (Table 1).

As regard to pain related to procedures according to pain score, patients experience discomfort or pain sensation with 3D GIS were lesser than OH so GIS was well tolerated and accepted by the patients (Table 2), these results were agreed with what was reported by (Van Den Bosch et al., 2009) [24].

As regards to complications experienced by patients during both procedures, complications were more obvious in OH particularly post procedure headache and bleeding (Table 3).

for 3D GIS, sensitivity, specificity, positive and negatice predictive values were 88.9%, 98%, 88.9% and 98% respectively (Table 5), these findings were comparable to findings of Yahia and Ahmed, (2015) who reported in their study that the overall sensitivity of GIS was 81% specificity 97.5%, positive predictive value 90% and negative predictive value 94%) [11]. Sensitivity and negative predictive value of 3D GIS in our study were higher than what was reported by Erika et al., 2011 (85.0% and 88.6%) respectively [25].

As regard to diagnostic value of 3D GIS in uterine cavity anomalies and intrauterine lesions, we found that 3D GIS had high sensitivity and specificity (100%) for mullerian duct anomalies and submucous fibroid but had the lowest specificity for intrauterine adhesions detection (66.7%) on the other hand positive predictive value was 100% for mullerian duct anomalies, submucous fibroid and intrauterine adhesions but 88.9 for intrauterine polyps (table 6). Negative predictive value of 3D GIS had high values for detection of uterine cavity anomalies and intrauterine lesions, these results is in agreement with what had been reported by Emanuel et al., 2009 who reported high accuracy of GIS in diagnosis of pedunculated polyp, sessile polyp, pedunculated myoma (89%) [26].

In our study the 3D GIS had high sensitivity, specificity, positive and negative predictive values in comparison to other studies in uterine cavity assessment so 3D GIS can be used as an alternative method for assessment of intrauterine lesions or presence of any congenital anomalies in the uterine cavity in infertility work up particularly in those under preparation for ICSI procedures because it safer, cheaper, noninvasive in comparison to hysteroscopy and can assess all other pelvic structures. 3 D TV U/S in coronal section can detect any abnormalities in mullarian duct fusion as biconuate uterus and uterine septum also 3 D TV U/S can measure endometrial volume and detect sub endometrial zone and assess uterine and ovarian blood velocity using Doppler u/s. The advantage of GIS over SIS that gel has slow uterine cavity filling and remains in cavity for a while that give chance for precise detection of any abnormalities or pathological lesion besides it is seldom pass from Ostia because of its high viscosity so no fear of any rarely allergic or inflammatory reaction in peritoneal cavity.


8. Conclusions


Uterine cavity assessment is mandatory prior to ICSI procedure. 3 D GIS had high sensitivity, specificity, positive and negative predictive values in detecting uterine cavity abnormalities comparable to OH. It is characterized by higher safety, lower cost, minimal invasion method with no need for anesthesia or analgesia and can be applied without special preparations in comparison to OH.


Recommendations


3 D GIS is to be used as an alternative to office hysteroscopy in uterine cavity assessment in patients with reproductive failure prepared for ICSI procedure.
