Falloposcopy is the endoscopic examination of the fallopian tubes, which are challenging to access due to their deep body location, small opening from the uterus, and lumen filled with plicae. We and others have developed endoscopes that are inserted through the uterus guided by a hysteroscope into the tubal ostium. To better understand how to utilize these endoscopes either as standalone devices or in concert with everting delivery balloons, a preliminary study of anatomy and mechanical behavior was performed ex vivo on porcine and human fallopian tubes. Segments of fallopian tubes from the isthmus, ampulla and infundibulum were inflated with saline either to bursting or held at sub-burst pressures with saline or a saline-filled balloon. Formalin fixed, paraffin embedded tissue sections stained with Masson\'s trichrome were examined for damage to the mucosa and muscularis. Porcine fallopian tubes tolerated saline pressurization at 15 psi for 1 minute without morphological damage. Balloon inflation to 15 psi caused no apparent damage to the muscle layer or rupture of the fallopian tube, but balloon movement within the tube can denude the mucosal epithelial layer. Human fallopian tubes averaged higher burst pressure values than porcine tubes. Under pressurization, the external tube diameter expanded by minimal to moderate amounts. Human and porcine tissues were similar in histological appearance. These studies suggest that moderate pressurization is acceptable but will not appreciably expand the fallopian tube diameter. The results also indicate that pigs are a reasonable model to study damage from falloscopy as seen in human tissue.

UNASSIGNED: Cervical ectopic pregnancy is one of the rarest forms of ectopic pregnancy. We present a single center case series of 10 cases of cervical ectopic pregnancy, where 3 patients underwent small-caliber hysteroscopy as a single treatment method.
UNASSIGNED: This was a retrospective study of women treated at our medical center with the diagnosis of cervical ectopic pregnancy from January 1, 2018 to December 31, 2020. Patient characteristics, medical history, obstetric history, diagnostic methods were collected. Small-caliber hysteroscopy treatment was performed in 3 patients and 7 patients underwent dilation and curettage (D&C).
UNASSIGNED: We identified 10 patients diagnosed with cervical ectopic pregnancy who were treated at our center. Ultrasonography was used to diagnose all cervical ectopic pregnancies Three patients underwent small-caliber hysteroscopy as a single treatment option, while D&C was performed in 7 patients. Patients who underwent small-caliber hysteroscopy had a median gestational age at diagnosis of 7 weeks and initial βHCG < 10,000 mIU/mL. These patients had shorter hospital stay and a lower estimated blood loss than patients who underwent D&C.
UNASSIGNED: In our experience, small-caliber hysteroscopy is a safe and effective single treatment option for cervical ectopic pregnancy, but requires a skilled and experienced gynecologist.

To identify technologies associated with the least operative pain in women undergoing operative office hysteroscopic procedures.
MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central Register of Controlled Trials were searched until January 2021 using a combination of keywords \"hysteroscop*,\" \"endometrial ablation,\" \"outpatient,\" \"ambulatory,\" \"office,\" and associated Medical Subject Headings.
Randomized controlled trials evaluating the effect of hysteroscopic devices on pain experienced by women undergoing operative office hysteroscopy were included. Data were also collected regarding efficacy, procedural time, adverse events, and patient/clinician acceptability and/or satisfaction.
The search returned 5347 records. Ten studies provided data for review. Two trials compared endometrial ablation using bipolar radiofrequency with thermal balloon energy, with no significant difference in pain observed (p <.05). Seven trials evaluated technologies for endometrial polypectomy, of which, 4 compared energy modalities: miniature bipolar electrode resection against resectoscopy (N = 1), morcellation (N = 2), and diode laser resection (N = 1). Two studies compared hysteroscope diameter, and one study compared methods of polyp retrieval. A significant reduction in pain was found using morcellators rather than miniature bipolar electrosurgical devices (p <.001), 22Fr rather than 26Fr resectoscopes (p <.001), and 3.5-mm fiber-optic hysteroscopes with 7Fr forceps rather than 5-mm lens-based hysteroscopes with 5Fr forceps (p <.05). One study investigating septoplasty showed significant reduction in pain when cold mini-scissors, rather than a miniature bipolar electrode, were used (p = .013). Average procedural times ranged from 5 minutes 28 seconds to 22 minutes. The incidence of adverse events was low, and data regarding efficacy and acceptability/satisfaction were limited.
Pain is reduced when mechanical technologies such as morcellators and scissors are used compared with electrical devices for removing structural lesions in the office. For hysteroscopic and ablative procedures, smaller and quicker devices are less painful. Large-scale RCTs investigating patient pain and experience with modern operative devices in the office setting are urgently needed.

Previous studies have investigated the impact of preoperative hysteroscopy on the staging and survival of predominantly grade 1 endometrial cancers. We sought to evaluate the effect of hysteroscopy on the peritoneal spread of tumor cells and disease course in a large series of patients with high-risk endometrial cancer.
Patients who underwent hysterectomy for grade 3 endometrial carcinoma on final surgical pathology at the Mayo Clinic in Rochester, MN between January 2009 to June 2016 were included, noting hysteroscopy within 6 months from surgery. Intra-peritoneal disease was defined as any positive cytology OR adnexal invasion OR stage IV. The presence of intra-peritoneal disease OR peritoneal recurrence within 2 years from surgery was defined as peritoneal dissemination. Cox proportional hazards models were fit to evaluate associations between hysteroscopy exposure and progression within 5 years following surgery.
Among 831 patients, 133 underwent hysteroscopy. There was no difference in age, body mass index, ASA ≥3, or serous histology between patients who did or did not undergo hysteroscopy. Advanced stage disease (III/IV) was less common among patients who underwent hysteroscopy (30.1% vs 43.8%, P=0.003). No difference was observed between those with vs without hysteroscopy in the rate of positive cytology (22.0% vs 29.7%, P=0.09), stage IV (16.5% vs 21.9%, P=0.16), intra-peritoneal disease (28.6% vs 36.1%, P=0.09), or peritoneal dissemination (30.8% vs 39.3%, P=0.06). On stratifying by stage, hysteroscopy did not increase the risk of progression (HR 1.06, 95% CI 0.59 to 1.92 for stage I/II; HR 0.96, 95% CI 0.62 to 1.48 for stage III/IV).
In this retrospective study of grade 3 endometrial cancer, we did not observe any significant association between pre-operative hysteroscopy and the incidence of positive cytology, peritoneal disease, peritoneal dissemination, or cancer progression.

This study sought to answer the following question: What are the complications and assisted reproductive technology outcomes among women with hydrosalpinges managed by hysteroscopic microinsert tubal occlusion compared with women with hydrosalpinges managed by laparoscopic proximal tubal occlusion or salpingectomy?
This was a retrospective cohort study conducted from January 2009 to December 2014 at two academic, tertiary care, in vitro fertilization centres in Toronto, Ontario. All patients (n = 52) who underwent hysteroscopic tubal occlusion for hydrosalpinges were identified. Patients who proceeded with embryo transfer cycles after hysteroscopic microinsert (n = 33) were further age matched to a cohort of patients who underwent embryo transfer after laparoscopic proximal tubal occlusion or salpingectomy (n = 33). Main outcome measures were clinical pregnancy rate per patient and per embryo transfer cycle.
Among 33 patients, there were 39 fresh and 37 frozen embryo transfer cycles in the hysteroscopic group (group A); among 33 patients in the laparoscopic group (group B), there were 42 fresh and 29 frozen embryo transfer cycles. The cumulative clinical pregnancy rate in group A and group B was similar (66.7% vs. 69.7%, respectively; P = 0.8). The clinical pregnancy rate per embryo transfer cycle was also similar in both groups (28.9% in group A vs. 32.4% in group B; P = 0.6). There were two incidents of ectopic pregnancy in the laparoscopic group and no ectopic pregnancy in the hysteroscopic group. There were three major complications: tubo-ovarian abscess, distal migration of the coil after microinsert placement, and an acute abdomen following the hysteroscopic procedure.
Pregnancy outcomes after hysteroscopic placement of a microinsert for hydrosalpinx management before embryo transfer were comparable to those following laparoscopic proximal tubal occlusion or salpingectomy. However, caution is advised regarding microinsert placement for hydrosalpinges before proceeding with assisted reproductive technology.

Surgical innovations in hysteroscopic surgery have radically changed the way of treating intrauterine pathologies, throughout the advent of the \'see-and-treat\' philosophy, which transferred the advantages of inpatient surgery to the office setting. However, in-office operative hysteroscopy was mainly limited to minor pathology as a supplement to its diagnosis, whereas commonly larger abnormalities were left to be treated in the operating room. Nowadays, pre-surgical assessment of uterine pathology is based on modern ultrasound evaluation and the evolving role of in-office hysteroscopy as a well-planned treatment modality for larger lesions and more complex procedures. Office operative hysteroscopy has been accepted as a feasible, cost-effective, practical way to treat almost any intrauterine disease. Despite the growing role of other imaging tools in the proper evaluation of benign uterine diseases, especially extended beyond to direct hysteroscopic visualization, diagnostic hysteroscopy remains a valuable tool of direct endometrial sampling and may be used as the first line in the diagnosis of endometrial cancer and hyperplasia. Our aim is to describe the most recent innovations and future perspectives in the field of outpatient operative hysteroscopy: mini-resectoscopes, intrauterine morcellators, tissue retrieval systems, diode laser, new miniaturized mechanical instruments, endometrial ablation devices and portable and entry-level hysteroscopes.

To report on the performance of hysteroscopic injection of tracers (indocyanine green (ICG) and technetium-99m (Tc-99m)) for sentinel lymph node (SLN) mapping in endometrial cancer.
Single-center retrospective evaluation of consecutive patients who underwent SLN mapping following hysteroscopic peritumoral injection of tracer. Detection rate (overall/bilateral/aortic) diagnostic accuracy, and oncologic outcomes were evaluated.
A total of 221 procedures met the inclusion criteria. Mean patient age was 60 (range 28-84) years and mean body mass index was 26.9 (range 15-47) kg/m2 . In 164 cases (70.9%) mapping was performed laparoscopically. The overall detection rate of the technique was 94.1% (208/221 patients). Bilateral pelvic mapping was found in 62.5% of cases with at least one SLN detected and was more frequent using ICG than with Tc-99m (73.8% vs 53.3%; p<0.001). In 47.6% of cases SLNs mapped in both pelvic and aortic nodes, and in five cases (2.4%) only in the aortic area. In eight patients (3.8%) SLNs were found in aberrant (parametrial/presacral) areas. Mean number of detected SLNs was 3.7 (range 1-8). In 51.9% of cases at least one node other than SLNs was removed. Twenty-six patients (12.5%) had nodal involvement: 12 (46.2%) macrometastases, six (23.1%) micrometastases, and eight (30.7%) isolated tumor cells. In 12 cases (46.8%) the aortic area was involved. Overall, 6/221 (2.7%) patients had isolated para-aortic nodes. Three false-negative results were found, all in the Tc-99m group. All had isolated aortic metastases. Overall sensitivity was 88.5% (95% CI 71.7 to 100.0) and overall negative predictive value was 96.5% (95% CI 86.8 to 100.0). There were 10 (4.8%) recurrences: five abdominal/distant, four vaginal, and one nodal (in the aortic area following a unilateral mapping plus side-specific pelvic lymphadenectomy). Most recurrences (9/10 cases) were patients in whom a completion lymphadenectomy was performed. No deaths were reported after a mean follow-up of 47.7 months.
Hysteroscopic injection of tracers for SLN mapping in endometrial cancer is as accurate as cervical injection with a higher detection rate in the aortic area. ICG improves the bilateral detection rate. Adding lymphadenectomy to SLN mapping does not reduce the risk of relapse.

Hysteroscopic evaluation of the endometrium with biopsy can be performed using different graspers whose terminal ends have specific features. This technical note aims to describe an innovative hysteroscopic grasper, the biopsy snake grasper sec. VITALE (Centrel S.r.l., Ponte San Nicolò, Padua, Italy), which can be used to grasp and cut at the same time. The characteristic features of this grasper are as follows: a sleeve with an opening along the whole width, a flat pointed tip with serrated edges fixed to its end by a U-shaped joint, and 2 sharp-edged jaws that completely encompass the tip when they are clenched. The biopsy snake grasper sec. VITALE, therefore, aims to be a useful innovative tool. It is a robust, easy-to-use instrument compatible with all modern hysteroscopes equipped with a 1.67-mm (5 French) working channel.

To introduce an effective method combining various endoscopes in the treatment of intravesical migrated intrauterine device (IUD).
A step-by-step explanation of the surgery using video, approved by the Shengjing Hospital of China Medical University.
Shengjing Hospital of China Medical University.
A 39-year-old young woman, in whom an IUD was inserted 2 months prior, presented with frequent urination after IUD insertion. Cystoscope and pelvic computed tomography were performed, and the results showed an IUD in the bladder. The migrated IUD was found partly in the uterus and partly in the bladder by hysteroscope and cystoscope. Management of the migrated IUD consists of 4 steps: (1) lysing the adhesion between the bladder and uterus, (2) suturing the bladder and taking the IUD part out of the bladder, (3) removing the IUD part in the uterus, and (4) suturing the bladder again to reinforce it and suturing the uterus.
The migrated IUD in the bladder was successfully and completely extracted by the method combining various endoscopes; operative time was 56 minutes. In the follow-up period the patient did not report any symptoms of frequency urination. This surgical process has the following characteristics: Preoperative examination should be performed to clarify the ectopic site of the IUD, various endoscopes should be combined for diagnosis and treatment, and endoscopic surgery is an effective treatment method for migrated IUD.

To demonstrate our technique for hysteroscopic resection of the complete uterine septum.
Step-by-step description and demonstration of the procedure using pictures and video (educational video). The video was approved by our hospital\'s Ethical Committee.
Uterine malformations represent a rare, yet usually asymptomatic condition that can be associated with poor obstetric outcomes. The European Society for Gynaecological Endoscopy(ESGE)/European Society of Human Reproduction and Embryology (ESHRE)classification is widely accepted for the description of female genital tract anomalies. Treatment of the uterine septum should be considered if fertility is desired, with hysteroscopic resection the gold standard procedure.
A patient with a U2bC2V1 malformation according to the ESGE/ESHRE classification was treated with hysteroscopy. The procedure was performed in the operating room under general anesthesia using a 9-mm hysteroscope with a bipolar cutting loop. Surgery began with resection of the vaginal septum with monopolar electrosurgery until the cervix was visualized. A Foley probe was placed in 1 uterine hemicavity, and then hysteroscopy on the other hemicavity was performed. Transrectal ultrasound guidance was used to identify the limits of the septum and thereby enhance the safety of the procedure. Resection of the septum started in the upper part until the Foley probe was seen, then continued downward until internal cervical orifice was reached. In the hysteroscopic follow-up after 3 months, we visualized a small residual septum that was resected to fully restore the uterine cavity and improve the patient\'s obstetric outcomes. The procedure was completed without complications, and a second-look hysteroscopy showed a normal uterine cavity.
The combination of real-time ultrasound guidance and placement of an intrauterine balloon through the cervix may increase safety during the procedure by providing clear visualization of the uterine cavity and septum border during resection.
