ABSTRACT
We compared surgical outcomes between single-port access total laparoscopic hysterectomy (SPA-TLH) and hybrid robotic single-site hysterectomy (RSSH), a new technique of combining the benefits of SPA-TLH with RSSH in this study. A total of 64 patients were retrospectively analyzed. They underwent either hybrid RSSH or SPA-TLH for benign gynecologic disease between December 2018 and August 2021. To assess the feasibility of hybrid RSSH, the clinical characteristics and surgical outcomes were compared between the hybrid RSSH group (n = 29) and the SPA-TLH group (n = 35). All of the surgeries were completed without requiring additional ports or conversion to laparotomy. The surgical outcomes including total operative time, uterine weight, estimated blood loss, hemoglobin changes, length of hospital stay, and postoperative pain scores were not significantly different between the two groups. The colpotomy time, including the detachment of the uterosacral and cardinal ligaments, was shorter in the hybrid RSSH group than in the SPA-TLH group (8.0 min vs. 14.0 min; p = 0.029). However, the vaginal cuff closure time was longer in the hybrid RSSH group than in the SPA-TLH group (15.0 min vs.10.0 min; p = 0.001). No difference was observed with regards to intraoperative and postoperative complications. Hybrid RSSH appears to be a feasible procedure for hysterectomy in patients with benign gynecologic diseases.
ABSTRACT
Background: Invisible cervical cancers on MRI can indicate less invasive surgery. Cervical cancers consist of squamous cell carcinoma (SCC) and non-SCC, each with different long-term outcomes. It is still unclear if surgical planning should be changed according to the histologic type of cervical cancer when it is not visible on MRI. Purpose: The purpose of the study was to determine if surgical planning for cervical cancer that is not visible on MRI is influenced by the histologic type. Materials and methods: Between January 2007 and December 2016, 155 women had Federation of Gynecology and Obstetrics (FIGO) stage 1B1 cervical cancer that was not visible on preoperative MRI. They underwent radical hysterectomies and pelvic lymph node dissections. Among them, 88 and 67 were histologically diagnosed with SCC and non-SCC, respectively. The size of the residual tumor, depth of stromal invasion, parametrial invasion, vaginal invasion, lymphovascular invasion, and lymph node metastasis were compared between these patients using the t-test, Mann-Whitney U test, Chi-squared test, or Fisher's exact test. The recurrence-free and overall 10-year survival rates were compared between the groups by Kaplan-Meier analysis. Results: The mean sizes of residual tumors were 8.4 ± 10.4 mm in the SCC group and 12.5 ± 11.9 mm in the non-SCC group (p = 0.024). The mean depth of stromal invasion in the SCC group was 12.4 ± 21.2% (0%-100%), whereas that in the non-SCC group was 22.4 ± 24.4 (0%-93%) (p = 0.016). However, there was no difference in parametrial or vaginal invasion, lymphovascular invasion, or lymph node metastasis (p = 0.504-1.000). The recurrence-free and overall 10-year survival rates were 98.9% (87/88) and 95.5% (64/67) (p = 0.246), and 96.6% (85/88) and 95.5% (64/67) (p = 0.872), respectively. Conclusions: The non-SCC group tends to have larger residual tumors and a greater depth of stromal invasion than the SCC group, even though neither is visible on MRI. Therefore, meticulous care is necessary for performing parametrectomy in patients with non-SCC cervical cancer.
ABSTRACT
The objective of the present pilot study is to compare operative outcomes between vaginal natural orifice transluminal endoscopic surgery (vNOTES) and single-port access (SPA) adnexectomy. Subjects were patients who underwent adnexectomy for benign adnexal disease, from November 2019 to May 2021. A total of 12 patients underwent vNOTES adnexectomy, and 55 patients received SPA laparoscopic adnexectomy. All surgeries were performed by one surgeon. In order to balance the baseline characteristics of the patients, 1:2 matching was performed. The vNOTES group demonstrated a low postoperative pain score within 12 h after surgery. They also required less use of analgesic medications postoperatively. Other surgical outcomes were comparable between the two groups. This study showed that vNOTES adnexectomy has comparable surgical outcomes to SPA.
ABSTRACT
Single-port access (SPA) laparoscopic surgery and vaginal natural orifice transluminal endoscopic surgery (vNOTES) have many advantages. The objective of the present study is to compare patient characteristics, operative details, and postoperative outcomes between the two surgical methods. Patients who were planned to undergo vNOTES or SPA laparoscopic surgery between April 2020 and June 2021 were prospectively enrolled. The surgical method was determined by a single surgeon after imaging results evaluation and a physical exam. Those who had favorable pelvic conditions without any evidence of adhesion were scheduled for vNOTES. A total of 33 patients underwent a vNOTES hysterectomy while 40 patients received a SPA laparoscopic hysterectomy. All surgeries were performed by one surgeon. The proportion of the patients who had a history of vaginal delivery was significantly higher in the vNOTES group. The operative time for port installation was significantly longer in the vNOTES group, but the total operative time was shorter compared to the SPA group. The postoperative pain scores 12 h after the operations were also significantly lower in the vNOTES group. Other surgical outcomes were comparable between the two groups. The present study demonstrated that the early operative outcomes of vNOTES hysterectomy were comparable to those of SPA hysterectomy. It also highlights the importance of adequate patient selection when determining surgical methods based on imaging results and physical examinations.
ABSTRACT
OBJECTIVE: To report a case of vulvar epithelioid sarcoma, a rare type of tumor that has been reported in 37 cases in the English literature to date. CASE REPORT: We report three cases of vulvar epithelioid sarcoma, proximal type. Wide excisions of the mass were performed with margins free of tumor in all three cases. CONCLUSION: Due to its low incidence, there are no evidence-based diagnostic algorithms or published recommendations for treatment. Locoregional lymph node involvement, vascular invasion, tumor size larger than 2 cm, deep localization, presence of necrosis, and a high mitotic index are known as poor prognostic factors. Adjuvant radiotherapy is advisable in the presence of a high-grade tumor or positive margins. The beneficial effect of adjuvant chemotherapy is not well established. Treatment decisions should be made based on the individual case presentation and pathology evaluation.

PURPOSE: This study evaluated the factors associated with endometrial pathologies during tamoxifen use in women with breast cancer. METHODS: This study analyzed 821 endometrial biopsies from women who received tamoxifen for breast cancer. Clinical characteristics were compared according to the presence of endometrial pathology (atypical hyperplasia and cancer). In addition, patients with endometrial polyps were compared with women with normal histology. RESULTS: Among 821 biopsies, atypical endometrial hyperplasia and cancer were diagnosed in 7 women each. Endometrial polyps were found in 173 women, and 634 women presented normal histology. In comparing women with endometrial pathology (atypical hyperplasia and cancer, n = 14) and those without pathology, parity was significantly lower (P = 0.014) and endometrial thickness was significantly higher (P < 0.001) in women with pathology. In addition, abnormal uterine bleeding was more common in the pathology group (P < 0.001). However, age, body mass index, menopausal status, intrauterine device use, history of diabetes mellitus, and duration of tamoxifen use did not differ according to the presence of pathology. In comparing women with endometrial polyps and those with normal endometrium, significant differences were found in parity (P < 0.001), duration of tamoxifen use (P = 0.003), and endometrial thickness (P < 0.001), but not in the presence of abnormal vaginal bleeding. CONCLUSION: Parity, endometrial thickness, and the presence of abnormal vaginal bleeding, but not age, body mass index, and menopausal status, may be associated with endometrial pathology during tamoxifen use in women with breast cancer. This finding might provide useful information for gynecological surveillance and counseling during tamoxifen treatment.
