Diagnostic office hysteroscopy; why is it still painful procedure despite the surgical experience and mini-hysteroscope?

AIM: To evaluate the effect of cervical canal features on pain during outpatient hysteroscopy performed by experienced surgeons using mini-hysteroscope. METHODS: A prospective observational study was conducted on 303 women undergoing diagnostic hysteroscopy without anesthesia. Pain intensity was evaluated using the visual analog scale (VAS) when the cervical canal was passed. The patients were divided into two groups according to the VAS score: painless or mild pain (VAS <4) and moderate or severe pain (VAS ≥ 4). The relationship between cervical canal characteristics (length, version, and flexion positions, history of cervical intervention, stenosis, synechiae), obstetric and gynecological history, preoperative anxiety level, procedure duration, and pain intensity was examined. RESULTS: Moderate pain (4 ≤ VAS < 7) was observed in 38% of patients (n = 117) and 14 patients (5%) experienced severe pain (VAS ≥ 7). In multivariate analysis, nulliparity (p = 0.01; OR, 4.6; 95% CI, 1.7-13.2), postmenopausal state (p = 0.02; OR, 2.2; 95% CI, 1.2-4.3), excessive flexion of the cervix and retroverted uterus (p <0.001; OR, 4.1; 95% CI, 2.0-8.5) were identified as risk factors for a painful procedure. Diagnostic hysteroscopy was successful in 98% of the patients. The pain was the primary cause of the failed hysteroscopy. CONCLUSION: In addition to nulliparity and postmenopausal status, unfavorable features of the cervical canal, such as the excessive flexion position of the cervix and uterine retroversion are significant causes of pain during outpatient hysteroscopy.

Surgical Management of Cesarean Scar Defect: The Hysteroscopic-Assisted Robotic Single-Site Technique.

STUDY OBJECTIVE: To educate surgeons on the advantages of robotic techniques in hysteroscopic-assisted single-site resection of cesarean scar defect. DESIGN: A step-by-step video presentation detailing the complete surgical procedure. SETTING: University Hospital, Baylor College of Medicine, Houston, Texas. PATIENTS: The first patient was a 34-year-old G2P2002 who complained of dysmenorrhea and menorrhagia, with an expressed desire for a single-site cesarean scar defect correction. Her surgical history included 2 cesarean deliveries, in 2012 and 2014. The second patient was a 34-year-old G4P3013 who complained of dysmenorrhea and a persistent mucus vaginal discharge, with an expressed desire for a cesarean scar defect correction in anticipation of conception. Her surgical history was notable for 3 previous cesarean deliveries. Neither patient's ultrasound report showed adenomyosis or any other pathologies. INTERVENTIONS: In both patients, hysteroscopic-assisted robotic single-site resection of the cesarean scar defect was performed, using a monopolar hook, wristed needle drivers, cold scissors, and a diagnostic vs operative hysteroscope. Entry was made through the umbilicus with a 15-mm incision and carried down through the subcutaneous tissue until the fascia was grasped and entered using Mayo scissors. The abdomen was inspected. The bladder was carefully disected off of the lower uterine segment and then backfilled to aid identification of the correct plane for dissection. Once the bladder was adequatetly dissected off of the uterus, the suspected defect could be identified. The monopolar hook was used to incise the defect, and the tip of the hysteroscope was placed through the defect to fully delineate it. The edges were trimed with cold scissors (Endoshears) in the first surgery and the monopolar hook in the second surgery. The uterine defect was closed with 2 layers of countinuous running V-Loc suture. The peritonium was closed with an additional V-Loc suture in a running fashion. Finally, hysteroscopy was performed. The closure was noted to be watertight, verifying successful repair of the defect. In the second case, an intercede was placed over the defect to help prevent future adhesive disease. In addition, after consulting with experts in cesarean scar repair, an energy device was recommended, and thus the monopolar hook over cold scissors was used for the second case due to its superior cutting effect. In both cases, the pelvis was inspected, and hemostasis was observed throughout. MEASUREMENTS AND MAIN RESULTS: The 2 cases had similar outcomes, with successful repair of the cesarean scar defect and resolution of the patient's symptoms. The thickness of the residual myometrium in cesarean scar defect was 2.8 mm in the first case and 2.3 mm in the second case. This video is exempt from Institutional Review Board review. In the first case, the surgery was completed in 90 minutes with only 15 mL of blood loss. The patient was discharged home on the day of surgery and denied any postoperative complications at her follow-up appointment. In the second case, the surgery was completed in 85 minutes with only 10 mL of blood loss. The patient was discharged home on the day of surgery. At her follow-up appointment, she had a positive pregnacy test and denied any postoperative complications. When contacted at a later date, she revealed that she was 15 weeks pregant. CONCLUSION: Hysteroscopic-assisted single site resection of a cesarean scar defect is a feasible method for the resection of cesarean scar defect. Use of the robot makes the difficult surgical techniques required for this operation easier and more accessible.

Compliance and diagnostic efficacy of mini-hysteroscopy versus traditional hysteroscopy in infertility investigation.

OBJECTIVE: The aim of this study was to compare traditional hysteroscopy with mini-hysteroscopy in terms of compliance, side effects and diagnostic efficacy. STUDY DESIGN: We prospectively considered 950 female candidates for an IVF programme. All women underwent outpatient hysteroscopy; in 602 cases (Group A) a mini-hysteroscope was employed; in 348 women (Group B) a 5-mm hysteroscope was adopted. RESULTS: Cavity findings were similar in both groups. Endometrial polyps and uterine septum seem to be more frequent in our infertile patients than in the general population. No significant differences in terms of side effects were found between the groups. Mean visual analogue pain scale score was significantly lower in the patients of Group A than in those of Group B (p<0.001). CONCLUSIONS: Office mini-hysteroscopy is a very effective diagnostic tool in an infertility work-up and is more widely accepted than traditional hysteroscopy. Routine use of the technique should be considered.

Tubal perforation by ESSURE microinsert.

Female tubal sterilization remains the most widely used method of permanent contraception worldwide. Recent studies have shown the new sterilization technique by ESSURE microinsert to be an effective method with decided advantages for the patient in terms of morbidity associated to a quick recovery. We discuss the possible hysteroscopic signs of tubal perforation and the right measures to take if a perforation is suspected, with respect to the possible complications and contraceptive failure.

Mechanisms of thermal injury to the lower genital tract with radiofrequency resectoscopic surgery.

STUDY OBJECTIVE: Identification of mechanisms of thermal injury to the lower genital tract during radiofrequency (RF) resectoscopic surgery. DESIGN: Laboratory comparative study using uterovaginal tissue models. SETTING: University surgical laboratory. PATIENTS: No patients involved. INTERVENTIONS: A tissue model was created to simulate the uterus, contiguous posterior vaginal wall, and the introitus. Instrumentation included a RF electrosurgical generator; a continuous-flow resectoscope; and rollerball electrodes, both intact and with insulation defects created in a standardized fashion. The resectoscope was serially activated, varying electrode insulation defects and RF waveforms and wattage, both in open-circuit conditions, with or without cervical contact, and with variable amounts of the external sheath within the simulated cervical canal. The cervix was either overdilated or minimally dilated so that the surrogate cervical tissue was snug to the external sheath. After activation of the generator, the external sheath was brought into contact with the proximal vagina and perineum, any visible arcing was noted, and tissue effects were visually graded according to a zero-to-three scale. MEASUREMENTS AND MAIN RESULTS: When the resectoscope was in contact with the cervix, the prerequisites for vaginal injury included cervical overdilation, a proximal electrode insulation defect, and less than 2 cm of the external sheath in the canal. There was greater risk with larger electrode insulation defects located beside the telescope, and there was a greater degree of coupling and injury with high voltage outputs. CONCLUSION: The incidence of vaginal and perineal burns associated with unipolar RF resectoscopes can likely be minimized by careful attention to technique.

Office hysteroscopy: comparison of 2.7- and 4-mm hysteroscopes for acceptability, feasibility and diagnostic accuracy.

OBJECTIVE: To compare 2.7- and 4-mm rigid optics, with 3- and 5-mm outer sheaths, respectively, in office diagnostic hysteroscopy by evaluating pain, patient tolerability, optical view and diagnostic accuracy of the procedure. STUDY DESIGN: Three hundred seventy-one consecutive patients undergoing hysteroscopy were included in a prospective, randomized clinical trial, and the outcomes were analyzed. A saline solution was used as the distension medium. The t test for unpaired samples, chi2 tables of contingency and ANOVA 2 x 3 were used where appropriate. The study took place at Tor Vergata University Hospital of Rome, Rome, Italy. The 371 women were referred consecutively for suspected endometrial pathologies and were separated into 2 groups. Diagnostic accuracy of the hysteroscopic procedure, pain experienced by the 2 groups (as assessed by a visual analogue score) and patient acceptability were assessed with a questionnaire. RESULTS: Satisfactory hysteroscopy was achieved in 253 of 310 patients with a 2.7-mm hysteroscope and in 47 of 61 patients with a 4-mm hysteroscope. This difference was not significant. Menopausal status was the most important factor influencing the practicability of the hysteroscopic procedure (p < 0.001). CONCLUSION: The narrower-diameter hysteroscopes tended to lower the incidence of pain associated with office hysteroscopy, but this was not significant. Parity did not show any influence on hysteroscopic practicability. Menopausal status was the most important factor influencing the feasibility of the hysteroscopic procedure.

Office hysteroscopy and compliance: mini-hysteroscopy versus traditional hysteroscopy in a randomized trial.

BACKGROUND: Diagnostic hysteroscopy has not yet been generally accepted as a well-tolerated office procedure. The aim of our study was to verify compliance, side-effects and haemodynamic variations when a mini-hysteroscope is used. METHODS: A prospective randomized trial on office hysteroscopy was performed by comparing the use of a traditional 5 mm hysteroscope (group A) and of a 3.3 mm mini-hysteroscope (group B). Two patient groups (A and B), each comprising 100 cases, were formed on the basis of a randomized computer-generated list. RESULTS: A marked reduction in the mean (+/- SD) pelvic pain score during office hysteroscopy was seen in group B (2.3 +/- 2.1) as compared with group A (4.6 +/- 2.2) (P < 0.0001, Mann-Whitney test). This result was also confirmed when using an alternative approach: four classes of pelvic pain at the visual analogue score (VAS). A significant reduction was observed in the incidence of moderate and severe pelvic pain in group B at the end of the examination (P = 0.001) and 5-10 min later (P < 0.05). CONCLUSIONS: The use of mini-hysteroscopes (3.3 mm with diagnostic sheath) lowers considerably the level of pelvic pain the patients feel: it is halved in comparison with traditional calibre hysteroscopes (2.3 +/- 2.1, on a 0-10 VAS). Furthermore the outpatient hysteroscopy failure rate is less than half (2%) with the mini-hysteroscope compared with the traditional 5 mm hysteroscope (5%). As for side-effects and haemodynamic parameters, no differences were observed except for an increase (P < 0.05) in bradycardia in group B. The advantage of this technique is self-evident, if the patients' compliance is taken into account: in many cases the introduction or withdrawal of the vaginal speculum was reported as the greatest discomfort.

Acceptance of outpatient flexible hysteroscopy by premenopausal and postmenopausal women.

OBJECTIVE: To compare tolerance for and feasibility of outpatient flexible hysteroscopy in premenopausal and postmenopausal women. STUDY DESIGN: A comparative, prospective study including 475 premenopausal and 216 postmenopausal women who underwent outpatient hysteroscopy without analgesia. RESULTS: Mean pain score was higher in postmenopausal patients (1.55 +/- 0.56 vs. 1.27 +/- 0.38 [P < .0001]). Outpatient flexible hysteroscopy was feasible without analgesia in 471/475 premenopausal (99.2%) and 210/216 postmenopausal women (97.2%) (P = .07). CONCLUSION: Outpatient flexible hysteroscopy was feasible and well tolerated; local anesthesia should be reserved for postmenopausal women.

Flexible versus rigid endoscopes for outpatient hysteroscopy: a prospective randomized clinical trial.

To evaluate patient acceptance, optical properties and the clinical feasibility of flexible compared with rigid hysteroscopes, 142 patients undergoing outpatient hysteroscopy were included in a prospective, randomized clinical trial. The flexible hysteroscope was used in 70 patients, and the rigid instrument in 72. At different stages of the hysteroscopy the level of pain experienced by the women was assessed using a 10 cm visual analogue scale. Optical properties characterized by the parameters intrauterine visibility, hysteroscopic view and diagnostic accuracy were ranked by the surgeons using a 5-point scale (1 = excellent to 5 = insufficient), and duration of the hysteroscopy was measured. Hysteroscopy was successful in 87.5 and 100% of patients in the flexible and rigid groups respectively. With the use of rigid telescopes, discomfort at introduction and during the hysteroscopy was significantly greater (median 1.7 versus 0.7, P = 0.003; 3.1 versus 1.2, P < 0.001 respectively), but optical properties were judged to be far superior (P < 0.001 for all three comparisons) and procedure time was significantly shorter (median 70 versus 120 s, P = 0.003). In conclusion, outpatient hysteroscopy seems to be less painful when using flexible telescopes. However, rigid hysteroscopes provide superior optical qualities and permit a more rapid performance with higher success rates at much lower cost.
