Dixon surgery for rectal cancer can lead to severe intestinal narrowing and blockage that is difficult to treat with open surgery or colonoscopy. The aim of the present study was to develop a minimally invasive approach for treating rectal anastomotic atresia based on three cases that were managed with transurethral prostate resection instrumentation. Preoperative imaging determined the distance from the anastomotic closure to the anal margin, the length of the anastomotic closure and the degree of proximal intestinal dilation for all cases. During the procedure, the anastomotic site was visualized, and a circular electrode was used to excavate and open the blockage. Membrane-like closures were directly incised to achieve satisfactory results, with an anastomotic diameter >20 mm. Those cases with tubular atresia required an initial incision using the prostate resectoscope to relieve the obstruction, followed by radial incisions until achieving an anastomotic diameter >20 mm. At 3-6 months post-dilation, two of the patients with anastomotic atresia >20 mm had satisfactory bowel movements, whereas the remaining patient experienced tumor recurrence at the anastomotic site and discontinued treatment. This case series demonstrates the potential of transurethral prostate resection instrumentation as a safe and effective minimally invasive approach for rectal anastomotic atresia. Given that prostate resection instrumentation is readily available in hospitals in China, this approach is widely accessible to most patients. Furthermore, the technique leverages existing surgical technology and practices, requiring only a shift in the surgical site.

OBJECTIVE
To compare ribonucleic acid (RNA) quantity and purity in tissue collected with different endometrial sampling methods to establish the optimal tool for use in endometrial gene expression studies.
DESIGN
Observational study.
SETTING
University hospital.
PATIENTS
Fourteen patients with submucosal leiomyomas.
INTERVENTIONS
Unguided biopsies were obtained using a low-pressure suction device before hysteroscopy from 14 patients with submucosal leiomyomas followed by guided biopsy with a resectoscope loop. Fifty-seven samples were collected: 25 obtained using a suction device and 32 with a loop.
MAIN OUTCOME MEASURES
Total biopsy weight, RNA purity, and RNA yield for each collection method. After complementary deoxyribonucleic acid synthesis, expression was measured by quantitative polymerase chain reaction in the endometrium overlying and remote from the leiomyoma, as similar expression throughout the cavity was a prerequisite for the use of unguided biopsy method.
RESULTS
The median weight of the samples was significantly larger when obtained with the low-pressure suction device than with the resectoscope loop (153 vs. 20 mg). The RNA yield was similar (suction curette, 1,625 ng/mg; resectoscope loop, 1,779 ng/mg). The A260-to-A280 ratio was satisfactory for 94.7 % of the samples, with no difference between the groups. The endometrial expression of was similar in areas overlying the leiomyoma compared with that in remote endometrial sites (2 = 0.0224 vs. 0.0225).
CONCLUSIONS
Low-pressure endometrial suction devices provide tissue samples with acceptable RNA purity and quantity for gene expression studies. The expression of did not differ between endometrial sampling sites even in the presence of leiomyomas.

We report the case of a woman with laminaria retention up to six years, followed by spontaneous pregnancy after the removal by hysteroscope of the intrauterine retained laminaria. A 26-year-old woman (G1P0) visited our hospital with complaints of prolonged menstrual bleeding, dyspareunia, and infertility. She had a history of dilatation and evacuation (D&E) at nine weeks of gestation six years earlier. A transvaginal ultrasound showed an artifact, and hysteroscopy revealed a long foreign body, which was suspected to be a laminaria retained after the prior abortion. In the hysteroscopic surgical procedure, the laminaria was cut, and the two halves were excised using resectoscope electrodes and hooked to the electrodes for removal. Thereafter, a year later, she conceived spontaneously and gave birth to a baby by cesarean delivery due to the arrest of labor progress. We are the first to present a pregnant case after the removal of a six-year retained laminaria.

BACKGROUND
In polypectomy with mechanical hysteroscopic morcellators, the tissue removal procedure continues until no polyp tissue remains. The decision that the polypoid tissues were removed completely is made based on visual evaluation. In a situation where the polyp tissue was visually completely removed and no doubt that the polyp has been completely removed, short spindle-like tissue fragments on the polyp floor continue in most patients. There are no studies in the literature on whether visual evaluation provides adequate information at the cellular level in many patients in whom polypoid tissues have been determined to be completely removed. The aim of the present study was to analyze the pathological results of the curettage procedure, which was applied following the completion of polyp removal with operative hysteroscopy, and to evaluate whether there was residual polyp tissue in the short spindle-like tissue fragments that the mechanical hysteroscopic morcellator could not remove. The secondary aims of this study were to compare conventional loop resection hysteroscopy with hysteroscopic morcellation for the removal of endometrial polyps in terms of hemoglobin/hematocrit changes, polypectomy time and the amount of medium deficit.
METHODS
A total of 70 patients with a single pedunculate polypoid image of 1.5-2 cm, which was primarily visualized by office hysteroscopy, were included in the study. Patients who had undergone hysteroscopic polypectomy were divided into two groups according to the surgical device used: the morcellator group (n = 35, Group M) and the resectoscope group (n = 35, Group R). The histopathological results of hysteroscopic specimens and curettage materials of patients who had undergone curettage at the end of operative hysteroscopy were evaluated. In addition, the postoperative 24th hour Hb/HCT decrease amounts in percentage, the polypectomy time which was measured from the start of morcellation, and deficit differences were compared between groups.
RESULTS
In total, 7 patients in the morcellator group had residual polyp tissue detected in the full curettage material. The blood loss was lower in the morcellator group than in the resectoscope group (M, R; (-0.07 ± 0.08), (-0,11 ± 0.06), (p < 0.05), respectively). The deficit value of the morcellator group were higher (M, R; (500 ml), (300 ml), (p < 0.05), respectively). The polypectomy time was shorter in the morcellator group (M, R; mean (2.30 min), (4.6 min), (p < 0.05)).
CONCLUSIONS
Even if the lesion is completely visibly removed during hysteroscopic morcellation, extra caution should be taken regarding the possibility of residual tissue. There is a need for new studies investigating the presence of residual polyp tissue.

Comparison of Efficacy of Vaginal Misoprostol versus a Synthetic Osmotic Dilator (Dilapan-S) for Cervical Preparation before Operative Hysteroscopy: A Randomized Controlled Study.
OBJECTIVES
To compare the need for mechanical cervical dilatation following vaginal misoprostol or synthetic osmotic dilator (Dilapan-S) usage for cervical preparation before operative hysteroscopy.
MATERIALS AND METHODS
Fifty-five premenopausal women scheduled for operative hysteroscopic procedures with a 26 Fr resectoscope were included in this randomized, controlled clinical trial. After randomization, either 400 μg of vaginal misoprostol or intracervical synthetic osmotic dilator (Dilapan-S) was inserted 12 h before operative hysteroscopy. The need for additional mechanical cervical dilatation before insertion of the resectoscope was compared between the two groups. Initial cervical diameter before mechanical dilatation, intraoperative complications (cervical tears, creation of a false passage), and ease of dilatation were also compared between the two groups.
RESULTS
In the misoprostol group, 92% of women required additional mechanical cervical dilatation, whereas only 36% of women in the Dilapan-S group required additional dilatation ( < 0.05). The median initial cervical diameter achieved with Dilapan was 9 mm (Q1: 7 mm; Q3: 10 mm), and with misoprostol, it was 6 mm (Q1: 4.5 mm; Q3: 8 mm) ( < 0.05). There was no significant difference in other outcome parameters between the two groups.
CONCLUSION
Synthetic osmotic dilator (Dilapan-S) is more efficacious than vaginal misoprostol at ripening the cervix before operative hysteroscopy.

Review
A case of delayed postoperative bleeding after excision of endometrial polyp using resectoscope in an infertile woman with von Willebrand disease:a case report and literature review.
Von Willebrand disease (VWD) is a bleeding disorder caused by a congenital quantitative reduction, deficiency, or qualitative abnormality of the von Willebrand factor (VWF). Here, we report a case of delayed postoperative bleeding in an infertile woman with endometrial polyps complicated by VWD. The patient was a 39-year-old infertile woman with type 2A VWD. At 38 years of age, she was referred to our hospital for infertility and heavy menstrual bleeding. Hysteroscopy revealed a 15-mm polyp lesion in the uterus. The patient was scheduled for transcervical resection (TCR) of the endometrial polyp. Gonadotropin-releasing hormone agonists were preoperatively administered to prevent menstruation. The VWF-containing concentrate was administered for 3 days according to guidelines. The patient was discharged on postoperative day 3 after confirming the absence of uterine bleeding. Uterine bleeding began on postoperative day 6. The patient was readmitted on postoperative day 7 and treated with VWF-containing concentrate for 5 days, after which hemostasis was confirmed. TCR surgery for endometrial lesions is classified as a minor surgery, and guidelines recommend short-term VWF-containing concentrate replacement. However, it should be kept in mind that only short-term VWF-containing concentrate replacement may cause rebleeding postoperatively.

Management of the posterior urethral valve (PUV) is a clinical challenge in pediatric urology. We report the results of a modified valve ablation method without using a pediatric resectoscope and thermal energy. Patients were selected from children with PUV who were referred to the pediatric urology clinic of Shahid Labbafinejad Hospital, Tehran, Iran, and have undergone endoscopic valve ablation surgery between May 2019 to May 2021. Ten male patients with PUV underwent mechanical valve ablation without the use of the conventional pediatric resectoscope, and thermal energy was replaced by a 6F semi-rigid urethroscope and 3Fr ureteral catheter. Patients were assessed both pre-and postoperatively using serum creatinine, urinary tract ultrasound imaging, and voiding cystourethrography. The mean age was 23.88±30.13 months (range= 25 days to 8 years). Four out of 10 patients (40%) had elevated serum creatinine, and seven had unilateral or bilateral hydroureteronephrosis (70%). No major complications were reported according to Clavien-Dindo Classification System. The level of serum creatinine, the grade of hydroureteronephrosis, and the ratio of the prostatic urethra to anterior urethra diameter in postoperative voiding cystourethrography were decreased. A decrease in serum creatinine level occurred in patients after valve ablation, but this decrease was not statistically significant (P=0.059). The decrease in hydroureteronephrosis grade on the right (P=0.006) and left (P=0.022) was statistically significant. There was no evidence of urethral stenosis or need for repeating resection. It can be concluded that our mechanical valve ablation method might be a safe and effective technique for PUV ablation.

BACKGROUND
An isthmocele is a myometrial defect in the site of the caesarean scar. In symptomatic women with abnormal uterine bleeding and secondary infertility, surgical correction can be considered. Most authors advocate that when there's a residual myometrium ≥ 3mm it can be corrected through resectoscopic approach and when < 3mm the treatment should be laparoscopic, eventually guided by diagnostic hysteroscopy. Both these techniques have important limitations; therefore, the authors propose combining both techniques, in the same procedure, in order to overcome them.
OBJECTIVES
To demonstrate the advantages of a surgical technique for correction of an isthmocele using both resectoscopic and laparoscopic resection.
MATERIAL AND METHODS
A stepwise demonstration of the technique with narrated video footage.
MAIN OUTCOME MEASURES
Intraoperative data and outcomes in the patient's follow-up.
RESULTS
One month after the surgery the patient was asymptomatic, reporting a resolution of the uterine abnormal bleeding, and the ultrasound showed a full correction of the isthmocele.
CONCLUSION
A combination of resectoscopic and laparoscopic resection, in correcting bigger isthmoceles, is a good option to fully excise all the fibrotic tissue.
LEARNING OBJECTIVE
This video aims to demonstrate the benefits of using a technique combining resectoscopic and laparoscopic resection for correcting larger isthmoceles.

OBJECTIVES
To compare intrauterine adhesion (IUA) formation after hysteroscopic removal (HR) of retained products of conception (RPOC) with IUA formation after ultrasound-guided electric vacuum aspiration (EVA) and externally validate the outcomes of an RCT.
STUDY DESIGN
This prospective cohort study was conducted from April 2015 until June 2022 in 2 Dutch teaching hospitals and one Belgian university hospital. Women opting for EVA underwent the procedure as soon as possible. In the HR group, the therapeutic hysteroscopy was performed at least eight weeks after the end of pregnancy. Postoperatively, an office second-look hysteroscopy was offered to all patients. Women were included if they had been diagnosed with RPOC ranging from 1 to 4 cm on ultrasound and did not want to participate in the RCT. EVA was performed using a Karman cannula. Operative hysteroscopy consisted either of hysteroscopic morcellation with the TruClear™ System or the Intrauterine BIGATTI Shaver or cold loop resection with a bipolar resectoscope.
RESULTS
Of 178 included women, 124 were treated with HR and 28 with EVA. Outcomes of HR and EVA did not differ significantly in terms of complications (5.6 % vs 3.6 %; p = 1.00). Second-look hysteroscopy showed IUAs in 14 of 91 women (15.4 %) after HR and in 1 of 16 (6.3 %) after EVA (p = .461). Completeness of removal was significantly higher (90.1 %) after HR than after EVA (68.8 %) (p = .035). Additional operative hysteroscopy was required in 14.3 % of the HR group versus 37.5 % in the EVA group (p = .036).
CONCLUSION
In our cohort study, no significant differences in IUAs or complications were found. RPOC removal with HR was more often complete than removal with EVA, and additional therapeutic hysteroscopy was less frequently required after HR. These findings need to be correlated with those of RCTs.

OBJECTIVES
To compare the efficiency and safety profile of conventional monopolar, bipolar plasmakinetic and holmium laser techniques for transurethral resection of bladder tumour.
METHOD
The prospective comparative study was conducted from July 2019 to May 2021 after approval from the ethicsreview committee of Kafrelsheikh University, Egypt, and comprised patients of either gender with primary non muscle invasive bladder cancer who qualified for transurethral resection of bladder tumour. The patients were stratified into low-risk group A, intermediate risk group B and high-risk group C in accordance with the guidelines of the European Association of Urology. Comprehensive cystoscopy and panendoscopy were done in all cases. Once panendoscopy was done, tumour resection was performed with monopolar resectoscope in group A, plasmakinetic resectoscope in group B and holmium laser in group C). Data was collected at preoperative, peroperative, postoperative and follow-up stages. Data was analysed using SPSS 21.
RESULTS
Of the 84 patients, 67(79.76%) were males and 17(20.23%) were females. There were 27(32.14%) patients in group A; 21(77.8%) males and 6(22.2%) females withy mean age 60.63±11.76 years. Group B had 32(38%) patients; 26(81.2%) males and 6(18.8%) females with mean age 65.34±7.55 years. Group C had 25(29.76%) patients; 20(80%) males and 5(20%) females with mean age 59.48±12.6 years. The mean follow-up period was 12.97±2.70 months in group A, 12.81±2.75 monthsin group B and 13.48±3.3 monthsin group C. Visualised complete resection was done in 23(85.8%) group A patients, 29(90.6%) group B patients and 24(96%) group C patients(p=0.018). Visualised complete resection, tumour multiplicity, tumour size, catheter duration, and hospital stay were significant predictors (p<0.05). Survival analysis showed 26(96.3%), 30(93.75%) and 25(100%) cases in groups A, B and C, respectively.
CONCLUSIONS
Bipolar plasmakinetic and holmium laser techniques were found to be more effective and safer than the conventional monopolar technique for transurethral resection of bladder tumour in patients with primary non-muscle invasive bladder cancer.
