Disease relevance of Hysteroscopy

• CONCLUSIONS: Switching from tamoxifen to anastrozole treatment significantly reduced the need for a second hysteroscopy and D&C due to recurrent vaginal bleeding or thickening of the endometrium in postmenopausal breast cancer patients with tamoxifen-induced endometrial abnormalities [1].
• OBJECTIVE: To study the effects of preoperative naproxen on postoperative and post-discharge outcome and consumption of analgesics in patients undergoing diagnostic hysteroscopy and laparoscopy for infertility [2].
• Carbon dioxide embolism following diagnostic hysteroscopy [3].
• CO2 hysteroscopy for diagnosis of cervical polyps was performed in 36 patients [4].
• CONCLUSIONS: There is a good overall agreement between 3D SIS and diagnostic hysteroscopy in classification of submucous fibroids [5].

High impact information on Hysteroscopy

• Bleeding diaries were collected, hysteroscopies were performed, endometrial biopsies were obtained for standardized histological evaluation, and VEGF histochemical immunostaining (H)-scores were assigned [6].
• The current study evaluated TF levels in endometrial bleeding (BL) and nonbleeding (NBL) sites obtained by camera-guided hysteroscopy during Norplant contraception [7].
• MATERIALS AND METHODS: The authors prospectively examined 138 women receiving tamoxifen by using transvaginal US, hysterosonography, and office hysteroscopy [8].
• OBJECTIVE: The purpose of this study was to evaluate the possible effect of the antihypertensive agent nifedipine (a calcium channel antagonist) on the endometrium of asymptomatic menopausal women by using transvaginal sonography, hysteroscopy, and endometrial sampling [9].
• The ATAC ('Arimidex', Tamoxifen, Alone or in Combination) adjuvant breast cancer trial: baseline endometrial sub-protocol data on the effectiveness of transvaginal ultrasonography and diagnostic hysteroscopy [10].

Chemical compound and disease context of Hysteroscopy

• METHODS: Postmenopausal women with breast cancer who were receiving tamoxifen, with ultrasonographic endometrial thickness greater than 4 mm or vaginal bleeding, had hysteroscopy with selective endometrial biopsies [11].
• Transient blood oxygen desaturation, hypercapnia, and coagulopathy after operative hysteroscopy with glycine used as the distending medium [12].
• Two women, one with refractory postabortion hemorrhage and the other with refractory postpartum hemorrhage, were managed with vasopressin, operative hysteroscopy, and a dilute vasopressin pack [13].
• In contrast, in cases of minor pathology (small polyps, mucosal elevations, crypts, hypervascularization), hysteroscopy with saline presented with significantly higher diagnostic accuracy (85.4%) compared with hysteroscopy with CO2 (64.6%) [14].
• CONCLUSION: Saline infusion sonography is an accurate and well-tolerated method to evaluate abnormal uterine bleeding, compared with hysteroscopy [15].

Biological context of Hysteroscopy

• CONCLUSIONS: Both misoprostol and laminaria were equally effective in inducing proper cervical priming prior to operative hysteroscopy with minimal time of cervical dilatation [16].
• The use of misoprostol as a cervical ripening agent in operative hysteroscopy [17].
• CONCLUSION: Women receiving tamoxifen, especially those who are asymptomatic, should be closely monitored by transvaginal sonography and hysteroscopy to detect endometrial pathologies [18].
• CONCLUSIONS: As it is not possible to distinguish direct and indirect fluid absorption during hysteroscopic surgery, measuring expired breath ethanol is insufficient to assess overall fluid balance, and continuous volumetric assessment is still required [19].
• Carbon dioxide hysteroscopy immediately after second trimester abortion [20].

Anatomical context of Hysteroscopy

• INTERVENTION(S): Application of lidocaine spray both to the surface of the cervix and into the cervical canal before performing hysteroscopy [21].
• Hysteroscopy showed a single tubular uterine cavity projecting to the left with a single left tubal ostium, consistent with a unicornuate uterus [22].
• Forty-nine women (Group I) had standard IVF-embryo transfer, while in 34 women (Group II) hysteroscopy and polypectomy were performed immediately following oocyte retrieval, the suitable embryos were all frozen, and the replacement cycle took place a few months later [23].
• An occlusive device of gamma polymerized hydrogel, a P-block, was applied in the isthmic part of the oviduct by trans-cervical hysteroscopy [24].
• In order to mimic the delivery of CO2 into the pelvic circulation during sustained hysteroscopic surgery, direct insufflation of CO2 was done into the femoral vein of six anesthetized ewes [25].

Associations of Hysteroscopy with chemical compounds

• The use of misoprostol prior to hysteroscopy in postmenopausal women [26].
• The diagnostic hysteroscopies were performed 4-6 weeks after the miscarriage, using CO2 as medium for uterine distention [27].
• There were no other significant differences in the outcome of hysteroscopy between the placebo and lignocaine groups, although there was a significant reduction in the use of additional anesthesia in both groups compared with historical controls [28].
• OBJECTIVE: Our purpose was to report transient complications associated with operative hysteroscopy with glycine used as the distending medium [12].
• In both cases, the injection of dilute vasopressin paracervically when coupled with operative hysteroscopy was quite effective in determining the cause of the bleeding and was instrumental in avoiding major operative procedures [13].

Gene context of Hysteroscopy

• OBJECTIVE: To report hemolytic crisis in a woman with glucose-6-phosphate dehydrogenase (G6PD) deficiency who underwent diagnostic hysteroscopy using endoscopic instruments sterilized in gluteraldehyde and phenol disinfectant [29].
• We conclude that local MTX administration via hysteroscopy after tubal ostium visualization is feasible [30].
• Routine hysteroscopy before entering an IVF programme should be seriously considered [31].
• The uterine cavity findings on HSG and at hysteroscopy were compared [32].
• Hysteroscopy was performed 1-2 weeks after the decline of beta-HCG concentrations to negative values [33].

Analytical, diagnostic and therapeutic context of Hysteroscopy

• CONCLUSION: Peritonitis can presumptively occur from sorbitol when it is used as a distending medium and should be considered on the differential diagnosis when a patient presents with abdominal pain immediately after hysteroscopy [34].
• OBJECTIVE: To evaluate the efficacy of treatment for infertility associated with endometriosis by selective tubal catheterization under hysteroscopy and laparoscopy [35].
• OBJECTIVE: To estimate endometrial thickness by transvaginal ultrasound technique (TVU) in patients treated with tamoxifen; and to compare the results with hysteroscopy and directed biopsy, and to relate the findings to curettage material [36].
• During a 70-month period, CO2 hysteroscopy was carried out on 52 pregnant women wearing IUDs with retracted tails [37].
• The findings from the endometrial sampling, combined with the evaluation of the uterine cavity using operative hysteroscopy (115), hysterectomy (74) or HSE (hysterosonographic examination) (166), were used as the true values [38].
