RESUMO
STUDY OBJECTIVE: Several studies have been published on hysteroscopic treatment of cesarean scar defect using the 26 Fr resectoscope. This study compared the effects of the 26 Fr resectoscope with those of the 16 Fr mini-resectoscope in terms of efficacy, safety profile, and peri- and postoperative complications. DESIGN: A prospective cohort study. SETTING: Tertiary care university hospital (S. Orsola-Malpighi, Bologna, Italy). PATIENTS: Three hundred and nine women having symptoms and with a cesarean scar defect diagnosis were divided into 2 groups according to a temporal criterion: from March 2012 to March 2015, 155 consecutive women (control group) underwent isthmoplasty with the 26 Fr resectoscope (Karl Storz, Tuttlingen, Germany), whereas from April 2015 to March 2018, 154 consecutive women (study group) underwent isthmoplasty with the 16 Fr mini-resectoscope (Gubbini system, Tontarra Medizintechnik, Tuttlingen, Germany). INTERVENTIONS: One hundred and fifty-five women (control group) underwent isthmoplasty with the 26 Fr resectoscope, and 154 women (study group) underwent isthmoplasty with the 16 Fr mini-resectoscope. The so-called "channel-like" 360° endocervical resection technique was applied. MEASUREMENTS AND MAIN RESULTS: The isthmoplasty time with the 2 resectoscopes, excluding cervical dilatation, was similar (pâ¯=â¯.25), whereas the overall surgical time was shorter in the case of the mini-resectoscope. The use of the 16 Fr mini-resectoscope was significantly associated with a reduced volume of distension medium used (p <.001) and a lower fluid absorption (p <.001). A significant increase (pâ¯=â¯.01) in postoperative complications in the control group (9/155; 5.8%) compared with the study group (1/154; 0.7%) was also found. No significant reduction in discharge time was observed between the 2 groups (pâ¯=â¯.13). Patient satisfaction immediately after surgery was significantly higher (p <.001) in the study group than in the control group. CONCLUSION: Isthmoplasty with a 16 Fr mini-resectoscope seems to be as effective as isthmoplasty with a 26 Fr resectoscope in reducing postmenstrual abnormal uterine bleeding and suprapubic pelvic pain. It is associated with a significant reduction in overall surgical time owing to the non-necessity of performing cervical dilatation. The 16 Fr mini-resectoscope facilitates surgery in small anatomical spaces such as the cervical canal and reduces the complication rate linked to blind maneuvers not respecting the uterine anatomy.

STUDY OBJECTIVE: To show the technique of hysteroscopic channel-like 360° repair of a cesarean scar defect performed with a Gubbini 16F miniresectoscope (GUBBINI system; Tontarra Medizintechnik, Tuttlingen, Germany). DESIGN: A step-by-step demonstration of the surgical technique using slides, pictures, and a video (an instructive video [Video 1]). SETTING: A university hospital (Bologna University Hospital, Sant'Orsola-Malpighi Polyclinic, Bologna, Italy). PATIENTS: A 35-year-old woman with a history of a previous cesarean section complaining of pelvic pain and postmenstrual spotting. INTERVENTIONS: With the vaginoscopic approach, the isthmocele was localized; a high-frequency 90° angled circular loop electrode and pure cutting current of 100 W were used to resect the fibrotic tissue of the proximal (step 1) and distal (step 2) part of the niche. We performed resection not only of the fibrotic tissue underneath the niche but also of the inflamed tissue placed around the niche and on the opposite site (the so-called channel-like 360° endocervical ablation). A high-frequency angled ball electrode was used to obtain focused coagulation of all residual inflamed tissue still present on the niche surface and on the cervical canal walls (step 3); the aim of this step is to facilitate the re-epithelialization of the cervical canal walls by the paraphysiological endocervical epithelium. The procedure was ended by controlling any bleeding of the endocervical vessels by reducing the inflow and pressure of the distending medium and by focused electrocauterization with a ball electrode (step 4). MEASUREMENTS AND MAIN RESULTS: The operative time was 14 minutes. The small diameter of a 16F resectoscope and the use of a miniaturized loop without cervical dilation allow the operative procedures to be performed without cervical dilation and without anatomic distortion of the defect, reducing the risk of complications. The small diameter of the sheaths also makes the surgical gesture faster with an easier and faster approach to the niche compared with isthmocele hysteroscopic standard surgery. CONCLUSION: The presence of a uterine scar defect is usually asymptomatic or refers to postmenstrual spotting with dark red or brown discharge, dysmenorrhea, dyspareunia, chronic pelvic pain, infertility, or a dull sensation after menstruation. Several factors may play a role in isthmocele development such as a low uterine incision, a deficient suturing technique of the uterine incision, and patient-related factors that impair wound healing or increase inflammation or adhesion formation. Different techniques were used as reconstructive therapies of the cesarean scar defect including laparoscopic or robot-assisted laparoscopic excision, vaginal repair, or hysteroscopic treatment. All of these procedures remove or ablate the niche fibrotic tissue with the aim of relieving symptoms. Asymptomatic cases should not be treated. According to the most recent literature, hysteroscopic repair of a cesarean scar represents an effective and safe surgical option in cases of a symptomatic isthmocele. The persistence of symptoms has been reported in up to 18% of cases, so adequate counseling should be performed before the procedure.

STUDY OBJECTIVE: To estimate the incidence of infection after diagnostic and operative hysteroscopic procedures performed in an in-office setting with different distension media (saline solution or CO2). DESIGN: Prospective, multicenter, observational study (Canadian Task Force classification II-2). SETTING: Tertiary women's health centers. PATIENTS: A total of 42,934 women who underwent hysteroscopy between 2015 and 2017. INTERVENTIONS: Of the 42,934 patients evaluated, 34,248 underwent a diagnostic intervention and 8686 underwent an operative intervention; 17,973 procedures used CO2 and 24,961 used saline solution as a distension medium. Patients were contacted after the procedure to record postprocedure symptoms suggestive of infection, including 2 or more of the following signs occurring within the 3 weeks after hysteroscopy: fever; lower abdominal pain; uterine, adnexal, or cervical motion tenderness; purulent leukorrhea; vaginal discharge or itchiness; and dysuria. Vaginal culture, clinical evaluation, transvaginal ultrasound, and histological evaluation were completed to evaluate symptoms. MEASUREMENTS AND MAIN RESULTS: Operative hysteroscopies comprised polypectomies (nâ¯=â¯7125; 82.0%), metroplasty (nâ¯=â¯731; 15.0%), myomectomy (nâ¯=â¯378; 7.8%), and tubal sterilization (nâ¯=â¯194; 4.0%). Twenty-five of the 42,934 patients (0.06%) exhibited symptoms of infection, including 24 patients (96%) with fever, 11 (45.8%) with fever as a single symptom, 7 (29.2%) with fever with pelvic pain, and 10 (41.7%) with fever with dysuria. In 5 patients with fever and pelvic pain, clinical examination and transvaginal ultrasound revealed monolateral or bilateral tubo-ovarian abscess. In these patients, histological examination from surgical specimens revealed the presence of endometriotic lesions. CONCLUSION: The present study suggests that routine antibiotic prophylaxis is not necessary before hysteroscopy because the prevalence of infections following in-office hysteroscopy is low (0.06%).

STUDY OBJECTIVE: To compare the costs of hysteroscopic polypectomy using mechanical and electrosurgical systems in the hospital operating room and an office-based setting. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Tertiary referral hospital and center for gynecologic care. PATIENTS: Seven hundred and fifty-four women who underwent endometrial polypectomy between January 20, 2015, and April 27, 2016. INTERVENTIONS: Hysteroscopic endometrial polypectomy performed in the same-day hospital setting or office setting using one of the following: bipolar electrode, loop electrode, mechanical device, or hysteroscopic tissue removal system. MEASUREMENTS AND MAIN RESULTS: The various costs associated with the 2 clinical settings at Palagi Hospital, Florence, Italy were compiled, and a direct cost comparison was made using an activity-based cost-management system. The costs for using reusable loop electrode resection-16 or loop electrode resection-26 were significantly less expensive than using disposable loop electrode resection-27, the tissue removal system, or bipolar electrode resection (p = .0002). Total hospital costs for polypectomy with all systems were significantly less expensive in an office setting compared with same-day surgery in the hospital setting (p = .0001). Office-based hysteroscopic tissue removal was associated with shorter operative time compared with the other procedures (p = .0002) CONCLUSION: The total cost of hysteroscopic polypectomy is markedly higher when using disposable equipment compared with reusable equipment, both in the hospital operating room and the office setting. Same-day hospital or office-based surgery with reusable loop electrode resection is the most cost-effective approach in each settings, but requires experienced surgeons. Finally, the shorter surgical time should be taken into consideration for patients undergoing vaginal polypectomy in the office setting, owing more to patient comfort than to cost savings.

OBJECTIVE: To evaluate the changes in (1) residual myometrial thickness (RMT), (2) cesarean scar defect (CSD) size, and (3) clinical symptoms, before and after channel-like (360°) hysteroscopic resection for the treatment of CSD. METHODS: A single-center, observational, prospective, cohort study was carried out enrolling all symptomatic patients of childbearing age, diagnosed with CSD and routinely scheduled for channel-like (360°) hysteroscopic resection from July 2020 to July 2021 at the Division of Gynecology and Human Reproduction Physiopathology, Department of Medical and Surgical Sciences, IRCCS Azienda Ospedaliero-Univeristaria di Bologna. University of Bologna, Italy. The primary outcome was the difference in mean RMT before and after the procedure. Secondary outcomes were the differences before and 4 months after the surgery in: (1) CSD size measured by transvaginal ultrasound, (2) visual analog scale (VAS) scores for the symptoms, and (3) abnormal uterine bleeding (AUB) rate. Lastly, patients' satisfaction was assessed by the global impression of improvement (PGI-I) score. RESULTS: We found a significant difference before and after the procedure in: (1) mean RMT (+2.0 mm; P < 0.001); mean size of the CSD (base: +1.6 mm; height: -2.5 mm; transverse diameter: -3.2 mm; volume: -263.7 mm3 ; P < 0.001); (2) mean VAS score for dyspareunia (-5.84; P < 0.001), dysmenorrhea (-8.94; P < 0.001), pelvic pain (-2.94; P < 0.001); (3) AUB rate (91% vs. 3%; P < 0.001). Lastly, the mean PGI-I score ± SD was 1.7 ± 0.9. CONCLUSION: Channel-like (360°) hysteroscopic resection for the treatment of patients with symptomatic CSD may lead to an increase in RMT, decrease in CSD, and improvement of symptoms after the procedure, with high patient satisfaction.

PURPOSE OF REVIEW: To review the treatments of the cesarean-induced isthmocele in restoring infertility, associated techniques, and the risks of complications associated with their use. RECENT FINDINGS: Isthmocele is a reservoir-like pouch defect on the anterior wall of the uterine isthmus located at the site of a previous cesarean delivery scar. The flow of menstrual blood through the cervix may be slowed by the presence of isthmocele, as the blood may accumulate in the niche because of the presence of fibrotic tissue, causing pelvic pain in the suprapubic area. Moreover, persistence of the menstrual blood after menstruation in the cervix may negatively influence the mucus quality and sperm quality, obstruct sperm transport through the cervical canal, interfere with embryo implantation, leading to secondary infertility. The removal of the local inflamed tissue may be performed by laparoscopic, combined laparoscopic-vaginal, or vaginal surgery, and operative hysteroscopy, a minimally invasive approach to improve symptoms and restore fertility. SUMMARY: Isthmocele occurs after cesarean section, a common method of delivery and one of the most frequent surgical procedures, so that its upward incidence appears likely to continue in the near future. Because of its minimal invasiveness, resectoscopy may be the better choice for treatment, yielding good therapeutic results.

The reproductive outcome in 41 consecutive patients with cesarean-induced isthmocele and secondary infertility was evaluated prospectively. Patients included menopausal women (mean [SD; 95% CI] age, 35 [4.1; 29-42] years), with fertility duration of 3 to 8 (4.6 [28]) years with isthmocele, postmenstrual abnormal uterine bleeding, and suprapubic pelvic pain. Transvaginal ultrasound and office hysteroscopy were used to diagnosis isthmocele. Complete fertility tests were performed to exclude other causes of infertility in both female and male participants. Operative hysteroscopy was performed to correct the cesarean scar defect, and histologic findings were evaluated. Correction of isthmocele via operative hysteroscopy was successful in all cases evaluated. Patients became pregnant spontaneously between 12 and 24 months after isthmoplasty. Thirty-seven of the 41 patients (90.2%) delivered via cesarean section, and 4 (9.8%) had a spontaneous abortion in the first trimester. Isthmoplasty resulted in resolution of postmenstrual abnormal uterine bleeding and suprapubic pelvic pain in all patients. Thus, it was concluded that surgical treatment of cesarean-induced isthmocele using a minimally-invasive approach (operative hysteroscopy) restores fertility and resolves symptoms in women with a cesarean section scar and secondary infertility.

Os instrumentos empregados na histeroscopia cirúrgica experimentaram grandes avanços nos últimos 30 anos e permitiram escolher desde ressectoscópios de 26 e 21 Fr. acoplados a corrente mono ou bipolar até a office hysteroscopy, que contempla o uso de sistemas operatórios de diâmetros semelhantes àqueles empregados na histeroscopia diagnóstica. Essas opções ampliaram e fortaleceram as possibilidades de indicação cirúrgicas, minimizaram riscos e reduziram acentuadamente as contra indicações. A introdução do minirressectoscópio de Gubbini de 16 Fr. na prática histeroscópica permitiu, graças ao seu diâmetro reduzido, a execução de procedimentos ambulatoriais com a técnica de slicing, que aumenta e facilita as possibilidades do see and treat ambulatorial. A funcionalidade do instrumento tem se revelado satisfatória, já que permite a passagem da corrente de mono para bipolar no mesmo ressectoscópio em uso e nas mesmas alças multiuso. A nossa casuística, que compreende 1.350 pacientes e inclui variadas patologias intrauterinas e endocervicais, demonstra uma eficácia de 100% do instrumento, cuja limitação, não categórica, subordina-se aos miomas com diâmetro superior a 3 cm.
The instruments employed in surgical hysteroscopy experienced great advances in the last 30 years, allowing operators to choose from resectoscopes of 26 and 21 fr. coupled with mono or bipolar current, to the use of office hysteroscopy, which contemplates the use of operating systems of diameters similar to those employed in diagnostic hysteroscopy. All these options have broadened and strengthened the possibilities of surgical indications, minimizing risk and reducing sharply the contraindications. The introduction of the miniresectoscope of Gubbini of 16 fr. thanks to its reduced diameter, enabled the implementation of outpatient procedures with the technique of slicing, increasing andfacilitating the possibilities of see and treat outpatient. The functionality of the instrument has proved to be satisfactory as it allows the passage of current from mono to bipolar in the same resectoscope in use and under the same multipurpose handles. Our series,comprising 1,350 patients and including various intrauterine and endocervical pathology, demonstrates an effectiveness of 100% of the instrument, whose limitation, not categorical, is subordinated to the fibroids with diameter greater than 3 cm.

STUDY OBJECTIVE: To produce and validate a simple, systematic and reproducible subclassification system for uterine anomalies previously classified by the American Ferility Society as Class V and VI to achieve a precise definition of each uterine anomaly, confirm the feasibility and safety of surgical correction of the anomalies, determine the type of hysteroscopic treatment, and provide a standard by which patient selection, treatment, and reproductive outcomes can be compared between centers. DESIGN: Descriptive study (Canadian Task Force Classification III). SETTING: Department of obstetrics and gynecology of a private clinic (hospital). PATIENTS: Eighty-nine patients undergoing office hysteroscopy to assess partial or complete "double" uterine cavity. INTERVENTIONS: All patients underwent 3-dimensional ultrasound. Data from hysteroscopy and untrasonography were combined to produce a geometric model comprising uterine septum length (Z variable) and fundus depth (Y variable) through which a new subclassification of the uterine anomalies was elaborated. MEASUREMENT AND MAIN RESULTS: One patient with a bicornuate uterus detected at ultrasonography was excluded from the study. The remaining 88 patients were classified according to our subclassification system. Seventy-three patients categorized as having Z 2 cm or greater (septum intersecting one-third of the uterine cavity or more) and Y more than 0 cm (normal or straight uterine fundus) underwent resectoscopic metroplasty without laparoscopic control. Twelve patients categorized as A1 (normal uterine fundus and septum < or =0.5 cm) underwent office metroplasty. Two patients categorized as B1 (straight fundus and septum < or =0.5 cm) and 1 categorized as C1 (concave fundus and septum < or =0.5 cm) were not considered candidates for surgery. Second-look hysteroscopy confirmed complete removal of the septum in the 12 patients who underwent office metroplasty (100%) and in 70 of 73 patients (96%) who underwent resectoscopic metroplasty. Comparison of these data with data retrospectively obtained in 596 women who had undergone traditional resectoscopic metroplasty under laparoscopic control did not demonstrate any significant difference in success and complication rates. CONCLUSION: Our outpatient subclassification system may address a precise diagnosis and a thorough categorization of patients with a partial or complete double uterine cavity, enabling safe and effective metroplasty without use of laparoscopy.

OBJECTIVE: To assess the accuracy of three-dimensional (3D) ultrasound in the diagnosis of congenital uterine anomalies. DESIGN: Prospective study. SETTING: University hospital. PATIENT(S): Nulliparae with three or more consecutive miscarriages. INTERVENTION(S): All women underwent 3D transvaginal ultrasound study of the uterine cavity. MAIN OUTCOME MEASURE(S): Women with negative ultrasound findings subsequently underwent office hysteroscopy, whereas a combined laparoscopic-hysteroscopic assessment was performed in cases of suspected Müllerian anomaly. RESULT(S): A specific Müllerian malformation was sonographically diagnosed in 54 women of the 284 included in the study group. All negative ultrasound findings were confirmed at office hysteroscopy. Among the women with abnormal ultrasound findings, the presence of a Müllerian anomaly was endoscopically confirmed in all. Concordance between ultrasound and endoscopy around the type of anomaly was verified in 52 cases, including all those with septate uterus and two out of three with bicornuate uterus. CONCLUSION(S): Volume transvaginal ultrasound appears to be extremely accurate for the diagnosis and classification of congenital uterine anomalies and may conveniently become the only mandatory step in the assessment of the uterine cavity in patients with a history of recurrent miscarriage.

STUDY OBJECTIVE: The obstetric complications that a cesarean delivery may produce have been known and studied for a long time. In the last few years, new correlations with some gynecologic disturbances also emerged, such as postmenstrual abnormal uterine bleeding (PAUB), and with some cases of secondary infertility. This is due to the presence of a diverticulum on the anterior wall of the uterine isthmus or of the cervical canal at the site of a previous cesarean delivery scar. The aim of our study was to assess the effectiveness of a hysteroscopic surgical technique to correct this anatomic defect and therefore eliminate the symptoms. DESIGN: A prospective study (Canadian Task Force classification III). SETTING: Private clinic and university hospital. PATIENTS: Twenty-six patients who previously had 1 or more cesarean deliveries, were evaluated from 2001 to 2005 for postmenstrual uterine bleeding and secondary infertility in 9 patients. All patients had a "niche" (which we defined as "isthmocele") principally on the isthmus-superior third of cervical canal (18/26), but on the lower cervical tract too (8/26). All of them underwent resectoscopic correction of the "isthmocele." INTERVENTIONS: Hysteroscopic resection of the edges and the bottom of the defect until the complete removal of the fibrotic scar tissue showing the muscular tissue below, using a cutting loop and pure cutting current. Aimed electrocoagulation of the bottom of the pouch with a roller-ball to avoid the in situ production of blood. MEASUREMENTS AND MAIN RESULTS: The anatomic defect in 100% of patients treated (26/26) was repaired, thus solving the symptom. Seven of 9 patients with secondary infertility became pregnant. CONCLUSIONS: The "isthmocele" represents a possible consequence of one or more cesarean deliveries and may be symptomatic in some women. It is a defect that can be easily diagnosed by hysteroscopy and successfully treated by resectoscopic technique.
