RESUMO
We report a case of robot-assisted total hysterectomy in a patient with extremely rare pelvic anatomy. Robot-assisted total laparoscopic hysterectomy was performed for lobular endocervical glandular hyperplasia on the left side of the uterus. The sigmoid colon was present between the two uterine corpora of a uterine didelphys and was attached to the bladder via the mesentery and fat. During surgery, the surgeon left the console and confirmed the magnetic resonance images. The surgery was then completed safely after the surgeon understood the anatomy. The postoperative condition was good, and the patient was discharged on postoperative day 5. Robot-assisted surgery has various advantages, including a good field of view, accuracy of instrument movement, and ease of viewing information in the medical record by pausing the operation. Robot assisted surgery improves not only safety and operational precision but also intraoperative convenience. Further studies are needed regarding the specific anatomy seen in this case.
RESUMO
Uterine adenomyosis is an estrogen-dependent tumor and one of the most common benign diseases in sexually mature women. The frequency of endometrial cancer associated with adenomyosis has been reported to be 18%-66%. On the other hand, endometrial cancer arising in adenomyosis (EC-AIA) is extremely rare. EC-AIA is now considered a different entity from and has a worse prognosis than endometrial cancer with adenomyosis (EC-A). In the present study, we report a case of endometrial cancer with adenomyosis in which endometrial biopsy failed to provide a definitive diagnosis. A 63-year-old female patient presented with endometrial thickening. Endometrial cytology was positive, and magnetic resonance imaging (MRI) showed small lesions suggestive of endometrial cancer with shallow invasion and adenomyosis. However, an endometrial biopsy showed only metaplasia, and careful follow-up was initiated. Subsequent endometrial cytology showed enlarged and round nuclei, uniform chromatin distribution, no thickening of nuclear margins, and abundant cytoplasm appearing in a sheet-like arrangement, suggesting atypical cells of endometrial glands with metaplasia. Three suspicious positive results and one positive result were observed, but repeated biopsies did not lead to the diagnosis of malignancy. The patient underwent diagnostic hysterectomy 19 months after the initial visit. The postoperative histopathological diagnosis was stage IA endometrial cancer (endometrioid carcinoma G1). This case of endometrial cancer associated with adenomyosis was difficult to diagnose. Our findings demonstrate that EC-AIA should be considered even if no lesions were detected by endometrial biopsy.
RESUMO
PURPOSE: To evaluate the efficacy of two progestins, levonorgestrel intrauterine system (LNG-IUS) and dienogest (DNG), for adenomyosis. METHODS: This study enrolled 157 women with adenomyosis, randomized to either LNG-IUS (n = 76) or DNG (n = 81) groups as a controlled clinical trial for 72 months. Participants were classified by three different localizations of adenomyosis: diffuse, focal, and extrinsic. VAS (Visual analog scale) score, days, and amount of uterine bleeding were assessed. Uterine volume or bone mineral density (BMD) were measured by three-dimensional ultrasonography or dual-energy X-ray absorptiometry. RESULTS: LNG-IUS and DNG comparably reduced pain scores in patients with adenomyosis. With regard to pain control, DNG offered greater efficacy than LNG-IUS in 3 months of treatment. In all types of adenomyosis, the days of bleeding after 12 months with DNG were significantly decreased compared to those with LNG-IUS. The decrease of whole uterine body was transient in any subtypes. A comparable decrease in BMD due to age-related changes in both groups was observed. CONCLUSIONS: LNG-IUS and DNG could be useful for long-term management of adenomyosis. In terms of durations of uterine bleeding, DNG was superior to LNG-IUS for 6 years.
