RESUMEN
Previous studies have rarely investigated the role of non-vitamin K oral anticoagulants (NOAC) and warfarin in the secondary prevention of ischemic stroke patients with nonvalvular atrial fibrillation (NVAF). In this study, we compared the effectiveness and safety of NOAC and warfarin for secondary prevention in Korean ischemic stroke patients with NVAF. Based on the Korean National Health Insurance Service Database, this study included 21,064 oral anticoagulants-naïve acute ischemic stroke patients with NVAF between July 2015 and June 2019. The main study outcomes included ischemic stroke, systemic embolism, major bleeding, and death. During the observational periods, NOAC users had a significantly decreased risk of ischemic stroke + systemic embolism (adjusted hazard ratio [aHR] 0.86; 95% confidence interval [CI] 0.78-0.95), ischemic stroke (aHR 0.89; 95% CI 0.81-0.99), major bleeding (aHR 0.78; 95% CI 0.68-0.89), and all-cause death (aHR 0.87; 95% CI 0.81-0.93). Standard-dose NOAC users had a lower risk of ischemic stroke, systemic embolism, and major bleeding events than warfarin users. In contrast, low-dose NOAC users did not differ in risk from warfarin users for all outcomes. In conclusion, NOACs were associated with a lower risk of secondary thromboembolic events and bleeding complications in Korean ischemic stroke patients with NVAF than warfarin.

BACKGROUND AND AIMS: No medication has been found to reduce liver-related events. We evaluated the effect of sodium-glucose cotransporter-2 inhibitor (SGLT2i) on liver-related outcomes. APPROACH AND RESULTS: Single nucleotide polymorphisms associated with SGLT2 inhibition were identified, and a genetic risk score (GRS) was computed using the UK Biobank data (n=337,138). Two-sample Mendelian randomization (MR) was conducted using the FinnGen (n=218,792) database and the UK Biobank data. In parallel, a nationwide population-based study using the Korean National Health Insurance Service (NHIS) database was conducted. The development of liver-related complications (ie, hepatic decompensation, HCC, liver transplantation, and death) was compared between individuals with type 2 diabetes mellitus and steatotic liver diseases treated with SGLT2i (n=13,208) and propensity score-matched individuals treated with dipeptidyl peptidase-4 inhibitor (n=70,342). After computing GRS with 6 single nucleotide polymorphisms (rs4488457, rs80577326, rs11865835, rs9930811, rs34497199, and rs35445454), GRS-based MR showed that SGLT2 inhibition (per 1 SD increase of GRS, 0.1% lowering of HbA1c) was negatively associated with cirrhosis development (adjusted odds ratio=0.83, 95% CI=0.70-0.98, p =0.03) and this was consistent in the 2-sample MR (OR=0.73, 95% CI=0.60-0.90, p =0.003). In the Korean NHIS database, the risk of liver-related complications was significantly lower in the SGLT2i group than in the dipeptidyl peptidase-4 inhibitor group (adjusted hazard ratio=0.88, 95% CI=0.79-0.97, p =0.01), and this difference remained significant (adjusted hazard ratio=0.72-0.89, all p <0.05) across various sensitivity analyses. CONCLUSIONS: Both MRs using 2 European cohorts and a Korean nationwide population-based cohort study suggest that SGLT2 inhibition is associated with a lower risk of liver-related events.

BACKGROUND AND AIMS: Metabolic dysfunction-associated fatty liver disease (MAFLD) encompasses heterogeneous fatty liver diseases associated with metabolic disorders. We aimed to evaluate the association between MAFLD and extrahepatic malignancies based on MAFLD subtypes. METHODS: This nationwide cohort study included 9 298 497 patients who participated in a health-screening programme of the National Health Insurance Service of Korea in 2009. Patients were further classified into four subgroups: non-MAFLD, diabetes mellitus (DM)-MAFLD, overweight/obese-MAFLD and lean-MAFLD. The primary outcome was the development of any primary extrahepatic malignancy, while death, decompensated liver cirrhosis and liver transplantation were considered competing events. The secondary outcomes included all-cause and extrahepatic malignancy-related mortality. RESULTS: In total, 2 500 080 patients were diagnosed with MAFLD. During a median follow-up of 10.3 years, 447 880 patients (6.0%) with extrahepatic malignancies were identified. The DM-MAFLD (adjusted subdistribution hazard ratio [aSHR] = 1.13; 95% confidence interval [CI] = 1.11-1.14; p < .001) and the lean-MAFLD (aSHR = 1.12; 95% CI = 1.10-1.14; p < .001) groups were associated with higher risks of extrahepatic malignancy than the non-MAFLD group. However, the overweight/obese-MAFLD group exhibited a similar risk of extrahepatic malignancy compared to the non-MAFLD group (aSHR = 1.00; 95% CI = .99-1.00; p = .42). These findings were reproduced in several sensitivity analyses. The DM-MAFLD was an independent risk factor for all-cause mortality (adjusted hazard ratio [aHR] = 1.41; 95% CI = 1.40-1.43; p < .001) and extrahepatic malignancy-related mortality (aHR = 1.20; 95% CI = 1.17-1.23; p < .001). CONCLUSION: The diabetic or lean subtype of MAFLD was associated with a higher risk of extrahepatic malignancy than non-MAFLD. As MAFLD comprises a heterogeneous population, appropriate risk stratification and management based on the MAFLD subtypes are required.

BACKGROUND: This study aimed to compare clinical and surgical outcomes of robotic single-port hysterectomy (RSPH) using the da Vinci® SP surgical system and robotic multisite hysterectomy (RMSH) with the da Vinci Xi system in benign gynecologic disease. METHODS: The retrospective study included 134 patients who underwent RSPH or RMSH between November 2019 and December 2020. Total operation time, amount of blood loss, and the change in hemoglobin (Hb) after surgery and the weight of the removed uteri were also measured. Data on complications such as post-operative fever and length of hospitalization were also compared and analyzed. RESULTS: There was no significant difference in the total operation time between the two groups, although the operation time was slightly longer in the RSPH group. Results in the RSPH group were superior to the RMSH group in docking time and wound incision time (1.67 ± 0.79 vs. 5.46 ± 2.25 min, p-value <0.01; 6.48 ± 4.29 vs. 9.10 ± 4.64 min, p-value <0.01, respectively). On the other hand, wound suture time took longer in the RSPH group (18.12 ± 5.66 vs. 10.69 ± 3.18 min, p-value <0.01). The weights of the removed specimens were higher in the RMSH group (302.64 ± 190.56 vs. 369.24 ± 181.70 g, p-value <0.04). The amount of blood loss during surgery and the difference in hemoglobin (Hb) before and after surgery were less in the RSPH group (97.39 ± 113.79 vs. 224.93 ± 152.29 mL, p-value <0.01, 1.51 ± 1.08 vs. 2.54 ± 1.08 g/dL, p-value <0.01). When considering the weight difference as a correction between the two surgical groups (because there were many heavier samples in the RMSH group), the blood loss of the RSPH group was also less than that of the RMSH group by 115.95 ± 23.78 mL (p-value <0.01). CONCLUSIONS: On the basis of our data, the robotic hysterectomy using the da Vinci SP surgical system might be feasible and safe, even if the hysterectomy is complex, and comparable to robotic multisite surgery by the da Vinci Xi system.

BACKGROUND: Although widely used in clinical fields, real-world data on the role of warfarin and non-vitamin K oral anticoagulants (NOACs) for the secondary prevention of thromboembolic complications in ischemic stroke patients with nonvalvular atrial fibrillation (NVAF) are scarce. AIMS: This retrospective cohort study compared the effectiveness and safety of secondary prevention of NOAC and warfarin in ischemic stroke patients with NVAF. METHODS: From the Korean National Health Insurance Service Database, we included 16,762 oral anticoagulants-naive acute ischemic stroke patients with NVAF between July 2016 and June 2019. The main outcomes included ischemic stroke, systemic embolism, major bleeding, and all-cause of death. RESULTS: In total, 1717 warfarin and 15,025 NOAC users were included in the analysis. After 1:8 propensity score matching, during the observation period, all types of NOACs had a significantly lower risk of ischemic stroke and systemic embolism than warfarin (edoxaban: adjusted hazard ratio [aHR], 0.80; 95% confidence interval [CI], 0.68-0.93, rivaroxaban: aHR, 0.82; 95% CI, 0.70-0.96, apixaban: aHR, 0.79; 95% CI, 0.69-0.91, and dabigatran: aHR, 0.82; 95% CI, 0.69-0.97). Edoxaban (aHR, 0.77; 95% CI, 0.62-0.96), apixaban (aHR, 0.73; 95% CI, 0.60-0.90), and dabigatran (aHR, 0.66; 95% CI, 0.51-0.86) had lower risks of major bleeding and all-cause of death. CONCLUSIONS: All NOACs were more effective than warfarin in the secondary prevention of thromboembolic complications in ischemic stroke patients with NVAF. Except for rivaroxaban, most NOACs demonstrated a lower risk of major bleeding and all-cause of death than warfarin.

OBJECTIVE: The purpose of this study was to assess health-related quality of life (HRQoL) in Korean patients with cervical cancer according to the duration of treatment and cancer progression of cervical cancer. METHODS: This study included 452 outpatients with cervical intraepithelial neoplasia (CIN) or invasive cervical cancer from six tertiary hospitals in South Korea. The questionnaire included the EQ-5D-3L instrument, patients' age, cancer progression (CIN or invasive cervical cancer), treatment duration (<1 year, ≥1 year but <2 years, and ≥2 years), treatment method (surgery, chemotherapy, radiation therapy), and presence of recurrence. HRQoL indices were calculated for these independent factors, and the mean was compared using ANOVA. Multiple regression analysis was performed to analyze factors affecting HRQoL in patients with cervical cancer. RESULTS: The EQ-5D index was 0.93 for patients with CIN, 0.87 for patients with invasive cervical cancer, and 0.78 for patients with recurrent invasive cervical cancer. HRQoL was significantly lower as the CIN progresses to cervical cancer. HRQoL of patients with invasive cervical cancer was lowest within 1 year of treatment in all stages. In addition, the HRQoL of patients with CIN or invasive cervical cancer who received chemotherapy and radiotherapy was lower than that of patients who underwent surgery. Multiple regression analysis showed that the HRQoL decreased significantly as increasing age, the first year of treatment after diagnosis, cancer recurrence, or chemotherapy. CONCLUSION: The HRQoL of patients with cervical cancer is affected not only by the stage of cancer progression but also by the duration of treatment and the type of treatment. As a result, when trying to apply the quality of life of patients with cervical cancer to cost-utility analysis, it is necessary to consider the duration and the type of treatment they receive.

AIM: To report our initial experience with robotic single-port myomectomy (RSPM) using the da Vinci SP surgical system and to evaluate the feasibility of the procedure. MATERIAL AND METHODS: This prospective observational study was performed at a university teaching hospital from January 2019 to December 2019. Sixty-one women with symptomatic fibroids received RSPM. RESULTS: Based on seven resected fibroids and a maximal diameter of resected fibroids <10 cm, the women were arbitrarily divided into two groups. The mean number and maximal diameter of the removed fibroids were 3.7 ± 3.8 (2.3 ± 1.8 in Group 1 vs. 7.2 ± 5.3 in Group 2) and 7.6 ± 2.9 cm (6.8 ± 1.6 in Group 1 vs. 9.5 ± 4.3 in Group 2), respectively. The mean operation time, hemoglobin change, and hospital stay were 149.9 ± 72.9 min (123.8 ± 43.8 in Group 1 vs. 217.6 ± 89.4 in Group 2), 2.3 ± 1.0 g/dL (2.1 ± 0.9 in Group 1 vs. 2.7 ± 1.2 in Group 2), and 4.5 ± 0.8 days (4.4 ± 0.8 in Group 1 vs. 4.7 ± 0.9 in Group 2). There was no conversion to multi-port laparoscopy or laparotomy nor were there any major complications. CONCLUSIONS: RSPM using the da Vinci SP surgical system is feasible surgical modality for women with symptomatic fibroid and is expected to increase indications of single-port myomectomy by solving many of the ergonomics problems inevitably accompanying single-port laparoscopic myomectomy.

OBJECTIVE: Ultrasonographic differential diagnosis of ovarian tumors is important for appropriate management. We conducted study to compare the performance of the Assessment of Different NEoplasias in the adneXa (ADNEX) model with a subjective assessment (SA) in differentiating between benign and malignant adnexal masses in Korean women. METHODS: A total of 353 patients who underwent adnexal surgery with abnormal pelvic ultrasonographic findings from August 2016 to August 2017 were included in study. The presumptive diagnosis of adnexal malignancy was determined by both SA and the ADNEX model to be >10% calculated risk of malignancy. The area under the curve (AUC) comparison between the SA and ADNEX models was performed using DeLong's method. RESULTS: 340 patients with benign tumors and 13 with malignant adnexal tumors among 292 (82.72%) premenopausal and 61 (17.28%) postmenopausal women were included. The AUCs of SA and the ADNEX model for discrimination between benign and malignant tumors were 0.79 and 0.92, respectively (P=0.10). The sensitivity and specificity of SA and the ADNEX model were 83.5% and 97.0%, and 90.0% and 82.0%, respectively. Comparison of the ADNEX model regarding menopausal status revealed that the predictability was not different. The AUCs of SA and the ADNEX model in premenopausal women were 0.74 and 0.89, respectively (P=0.12). The AUCs of SA and the ADNEX model in postmenopausal women were 0.86 and 0.94, respectively (P=0.60). CONCLUSION: The ADNEX model offers excellent discrimination between benign and malignant ovarian tumors with similar sensitivity and specificity to SA in both premenopausal and postmenopausal Korean women.
RESUMEN
OBJECTIVE: The gold standard procedure for treating patients with apical pelvic organ prolapse (POP) is sacrocolpopexy. However, no report comparing the two types of single-incision robotic sacrocolpopexy, namely, single-site robotic sacrocolpopexy (SS-RSC) and single-port robotic sacrocolpopexy (SP-RSC) exists. Therefore, we compared the safety and effectiveness of SS-RSC and SP-RSC. MATERIALS AND METHODS: In this study, 48 patients who underwent single-incision RSC, 40 non-consecutive patients who underwent SS-RSC, and 8 consecutive patients who underwent SP-RSC for symptomatic POP quantification stage III-IV and were eligible for the 1-year follow-up (FU) were included. We compared the surgical time and operative outcomes of SS-RSC and SP-RSC. We also compared the data of the initial 8 cases in each group. RESULTS: The mean patient age was 59.2 ± 11.0 years and 66.1 ± 8.0 years in the SS-RSC (n = 40) and SP-RSC (n = 8) groups, respectively. The mean operative time (OT) and console time were comparable between the SS-RSC and SP-RSC groups (135.3 ± 31.6 min vs 141.8 ± 23.5 min; 94.6 ± 32.2 min vs 89 ± 9.5 min, respectively). The docking time and cervix suturing time were short in the SP-RSC group (P < 0.05). However, in the analysis of the initial 8 cases in each group, all surgical times except the cervix suturing time were shorter in the SP-RSC group (P < 0.05). Three cases had intraoperative bladder injury (two [5.0%] in the SS-RSC and one [12.5%] in the SP-RSC group). Two cases (5.0%) had umbilical incisional hernia in the SS-RSC group. Two cases had vaginal mesh erosion on the posterior vaginal wall, with 1 case in each group. One case (2.5%) experienced a recurrence of POP; an anterior compartment POP-Q stage 2 following SS-RSC at the 4-week FU. CONCLUSION: Single-incision RSC, both SS-RSC and SP-RSC, is a feasible and effective surgical option for treating symptomatic apical POP with an aesthetic finish.

OBJECTIVE: This study aimed to demonstrate the use of preoperative magnetic resonance imaging (MRI) findings to select the optimal surgical technique between single-site (SS) and multi-site (MS) robotic myomectomy based on clinical experience, for the preservation of fertility. METHODS: Ninety-eight patients who underwent SS or MS robotic myomectomy using the da Vinci® Si system after undergoing MRI were evaluated retrospectively. The correlation between preoperative MRI findings and the intraoperative or postoperative findings during robotic myomectomy for the preservation of fertility was analyzed. The reproductive outcome was investigated when the patient wished to conceive. RESULTS: The mean age of the patients was 35.68±5.04 years and 80 patients (81.6%) were nulliparous. The total diameter of myomas on MRI was 106.75±54.52 mm. The number of resected myomas was 4.31±4.39 (range, 1-27), and the total weight of resected myomas was 293.11±281.13 (range, 30-1,260) g. Myomas with high signal intensity on MRI required less time for resection. MS robotic myomectomy was performed for an increased number and total diameter of a myoma or a deep-seated myoma. Postoperatively, all patients resumed normal menstruation. Of the 15 patients who wished to conceive, 12 (80%) conceived successfully. Of these, uterine dehiscence occurred in 1 patient and 10 patients underwent an uneventful cesarean section. CONCLUSION: SS or MS robotic myomectomy can be recommended for patients who wish to conserve fertility. However, the optimal surgical technique should be selected based on preoperative MRI findings to predict an effective surgical process and the successful preservation of fertility.
RESUMEN
AIM: The purpose of this study was to report on 626 cases of successful robotic single-site (RSS) surgeries to address various types of gynecologic disease and to evaluate the outcomes and learning curve inherent to RSS surgery in the gynecology field. METHODS: A total of 626 cases of RSS surgeries were performed by 3 gynecologic surgeons at Ewha Womans University Medical Center, Robot Surgery Center from November 2014 to January 2018 were collected retrospectively. All of the patients' charts were reviewed, and the clinical characteristics and surgical variables were analyzed. RESULTS: Among the total of 626 cases, there were 220 cases of RSS myomectomy (RSSM), 182 cases of RSS hysterectomy (RSSH), 195 of RSS adnexectomy, 24 of RSS sacrocolpopexy (RSS SCP) and 5 were classified as other RSS surgeries. The patient's mean age was 38.98 ± 10.07 years. There was 3.99 ± 2.15 min of mean docking time and 117.78 ± 51.18 min of mean operating time. The surgical variables were analyzed annually. The total operating time was seen to decrease significantly according to each period. The docking time declined significantly and gradually after 1 year. We also analyzed each of the surgical types by time. The operating time of RSSH, RSSM, RSS adnexectomy and RSS SCP fell over time. The tendency found was for operating time to decline sharply following the first 10 cases. When we analyzed the data at annual intervals, the operating time was most significantly less and stable following the first year. There were a few intraoperative or perioperative complications in 16 cases (2.6%). CONCLUSION: Robotic single-site surgery is a feasible and safe procedure for treating various kinds of gynecologic diseases. The learning curve was approximately 10 cases of RSS surgery in gynecologic disease, having a greater amount of experience at performing RSS surgery was revealed to be key to achieving better surgical outcomes.

OBJECTIVE: We aimed to present our initial experience with robotic single-port surgery performed using the da Vinci® SP surgical system for benign gynecologic diseases. MATERIALS AND METHODS: This retrospective cohort study was performed at an academic tertiary care hospital From December 2018 to January 2019. Thirty-one women with benign gynecologic diseases underwent robotic single-port surgery performed using the da Vinci® SP surgical system. RESULTS: During the study period, hysterectomy, myomectomy, adnexectomy, and sacrocolpopexy were performed in seven, twelve, five, and seven women, respectively. The mean age and body mass index of patients, respectively, were 47.7 ± 12.8 years and 22.7 ± 3.1 kg/m2. In terms of operative outcomes, the mean docking time, operating time, estimated blood loss, and hospitalization time were 2.2 ± 2.1 min, 126.3 ± 61.6 min, 93.9 ± 76.9 mL, and 4.6 ± 0.7 days. There was no laparoconversion or major complication. CONCLUSION: Robotic single-port laparoscopy using the da Vinci® SP surgical system might be a suitable alternative surgical technique for various benign gynecologic diseases. However, further studies are required to clarify the feasibility and safety of the application of this novel robot surgical system.

BACKGROUND: The appropriate level of positive end-expiratory pressure (PEEP) during intra-operative mechanical ventilation remains unclear. OBJECTIVE: The aim of this study was to investigate the effects of different levels of PEEP with low tidal volume (low-VT) ventilation in a steep Trendelenburg position (30°) and pneumoperitoneum on oxygenation, respiratory mechanics and ventilation distribution using electrical impedance tomography. DESIGN: A randomised controlled trial. SETTING: Single university secondary care centre, conducted from January 2017 to December 2017. PATIENTS: Forty female patients, aged 20 to 60 years, and of American Society of Anesthesiologists' (ASA) physical status 1 or 2, undergoing elective robotic gynaecological surgery were included. INTERVENTION: Forty patients were allocated randomly to a PEEP4 (PEEP 4âcmH2O) group or a PEEP8 (PEEP 8âcmH2O) group. MAIN OUTCOME MEASURES: The primary outcomes were respiratory mechanics. The secondary outcomes included changes in ventilation distribution across the ventral and dorsal regions of interest and postoperative pulmonary complications (PPCs) using a modified clinical pulmonary infection score. RESULTS: There was no difference in PaO2 at any time point. The peak inspiratory pressure (PIP) and mean airway pressure (MPAW) of the PEEP4 group were lower than those of the PEEP8 group (Pâ<â0.001). The oxygenation factor in the PEEP4 group was higher than that in the PEEP8 group during mechanical ventilation at all times. There was no difference in the fractional distribution of end-expiratory ventilation according to region of interest between the two groups. CONCLUSION: Both 4 and 8âcmH2O of PEEP with low-VT ventilation can be used for robotic gynaecological surgery that requires a steep Trendelenburg position and pneumoperitoneum. However, 8âcmH2O of PEEP had no benefit over 4âcmH2O of PEEP with respect to oxygenation and improvement of dorsal regional ventilation. TRIAL REGISTRATION: The trial was registered at the Clinical Trial Registry of Korea (KCT0002255). https://cris.nih.go.kr.

Misoprostol is widely used in daily practice for induction of labor and cervical dilatation prior to intrauterine procedures, including dilatation and curettage or hysteroscopy. Anaphylactic shock to intravaginal misoprostol can occur not only in pregnant women, as reported in 2 previous cases, but also in a non-pregnant, perimenopausal woman, as in the case described herein. A 49-year-old woman received vaginal misoprostol for cervical ripening prior to hysteroscopic myomectomy and experienced anaphylactic shock. Two 400 µg doses of misoprostol 6 hours apart caused uncontrolled shaking and high fever followed by shock. In conclusion, the possibility of anaphylactic shock should be considered in patients with sudden hypotension following misoprostol administration. Prompt identification and management are crucial to prevent morbidity and mortality following an anaphylactic shock to misoprostol.
RESUMEN
Objective: To compare perioperative outcomes of robotic single-site (RSS) surgery with conventional single-port laparoendoscopic surgery for the treatment of advanced-stage endometriosis. Materials and Methods: This is a retrospective cohort study that included 120 patients who received single-port laparoendoscopic surgery or RSS surgery for the treatment of advanced-stage endometriosis at Ewha Womans University's Mokdong Hospital in Seoul, Korea between December 2014 and May 2017. Single-port laparoendoscopic cystectomy and adhesiolysis were performed in 52 patients (Single-port laparoendoscopic [SPL] group) and RSS cystectomy and adhesiolysis were performed in 68 patients (RSS group). Perioperative outcomes that we analyzed, included age, operative time, estimated blood loss, length of hospital stay, size of endometriosis, laterality of endometriosis, degree of endometriosis infiltration (i.e., deep versus not), and recurrence. Results: The patients in both groups were of similar ages. Longer operative times (107.8 ± 37.6 min for RSS group versus 76.9 ± 46.4 min for SPL group, P = .001) and more estimated blood loss (106.67 ± 171.67 mL for RSS group versus 57.1 ± 44.9 mL for SPL group, P = .001) were measured in the RSS group. However, the mean size of endometriosis was statistically larger (5.23 ± 2.53 cm for RSS group versus 4.37 ± 2.14 cm for SPL group, P = .030) and higher rates of more deeply infiltrative endometriosis (52 cases in RSS group, 76.5% versus 33 cases in SPL group, 63.5%) were observed in RSS group. Multicystic endometriosis occurred in 26 cases in the RSS group (38.2%). No significant differences were seen in terms of length of hospital stay (4.58 ± 0.61 of SPL group versus 4.59 ± 0.58 of RSS group, P = .862) or intraoperative and postoperative complications between the groups. Recurrence occurred in one case in the RSS group (1.9%). Conclusion: RSS surgery can be used in the treatment of advanced-stage endometriosis, especially in more complicated cases.

OBJECTIVES: Using the da Vinci single-site platform, surgeons can perform more minimally invasive surgery. However, surgical challenges exist due to the limitations of single-site instrumental movements. To aid in the performance of successful robotic single-site hysterectomy, a new suturing technique using the current set of limited instruments is introduced in this study. MATERIAL & METHODS: New vaginal cuff suturing techniques have been used in 55 robotic single-site hysterectomies in our institute over the past 2 years. A needle driver approach utilizing screwing and advancing the needle driver in the correct direction at an increasing angle from the transverse cuff margin with dragging and formation of an adequate loop of thread was used when suturing the vaginal cuff. RESULTS: Using the new vaginal suturing techniques, easy and firm vaginal cuff closure with reduced operative time relative to previous hysterectomies was achieved. CONCLUSION: The new vaginal cuff suturing techniques may convince more surgeons to perform robotic single-site hysterectomies more frequently and with greater ease.

OBJECTIVE: The objective of this study was to investigate the incidence of unexpected uterine malignancy (UUM) diagnosed after hysteroscopic surgery for presumed submucosal leiomyomas or endometrial polyps. STUDY DESIGN: From the Korean national health insurance database between January 1, 2009 and December 31, 2015, we analyzed inpatient sample data that were extracted by a stratified random sampling (gender and age) method. We extracted women with or without UUM that was diagnosed after hysteroscopic surgery using diagnosis codes and procedure codes. RESULTS: A total of 11,866 women who underwent hysteroscopic surgery were extracted from 4,476,495 women. The mean age of the patients who underwent hysteroscopic surgery was 37.8⯱â¯0.1â¯years. A hysteroscopic myomectomy or polypectomy was performed in 3498 and 8368 women, respectively. The incidence of UUM diagnosed after hysteroscopic myomectomy or polypectomy was 0.86% and 1.11%, respectively. The logistic regression analysis showed that the risk of UUM increased with age (Odds Ratio (OR), 1.61; 95% Confidence Interval (CI), 1.47-1.77; Pâ¯<â¯0.001) and did not indicate hysteroscopic myomectomy or polypectomy (OR, 1.21; 95% CI, 0.93-1.55; Pâ¯=â¯0.151). CONCLUSIONS: The incidence of UUM diagnosed after hysteroscopic myomectomy (0.86%) or polypectomy (1.11%) was higher than that of UUM diagnosed after hysterectomy (0.19%) or myomectomy (0.12%) for presumed benign leiomyoma. The incidence of UUM increased over the age of 50.

PURPOSE: Rectus sheath block (RSB) is an anterior abdominal wall block that reduces postoperative pain associated with midline incisions. This study aims to investigate the effect of ultrasound-guided bilateral RSB (US-BRSB) on postoperative pain and analgesic consumption in patients undergoing laparoscopic gynecologic surgery. METHODS: Sixty patients who underwent laparoscopic gynecologic surgery were allocated to RSB (n = 30) or control (n = 30) group. A bilateral US-BRSB procedure (30 ml of 0.25% ropivacaine) was performed after induction of general anesthesia in the RSB group. The control group proceeded the surgery without sham block. All patients received fentanyl-based intravenous patient-controlled analgesia and rescue analgesics upon demand. Pain was scored by a blinded observer using a verbal numerical rating scale (VNRS) at rest while coughing at 0, 1, 6, 12, 24, and 48 h after postanesthesia care unit (PACU) admission. The primary outcome was the total number of rescue analgesics used in the 48-h postoperative period. RESULTS: At 0 h, VNRS were lower in the RSB group than in the control, both at rest (median VNRS 4.5 vs. 5, p = 0.02) and while coughing (median VNRS 6 vs. 7, p = 0.004). At 6 h, VNRS scores were lower in the RSB group than in the control while coughing (median VNRS 3 vs. 5, p = 0.01). Fentanyl use as rescue analgesics in the PACU was significantly lower in the RSB group than in the control (27.7 ± 32.1 vs. 53.3 ± 33.7 µg, respectively; p = 0.004). At 48 h postoperatively, the total number of rescue analgesics administered were significantly fewer in the RSB group than in the control (2.5 ± 2.5 vs. 3.9 ± 2.6, respectively; p = 0.04). CONCLUSION: US-BRSB reduces the immediate postoperative pain and opioid consumption during the early postoperative period. CLINICALTRIALS.

OBJECTIVE: Endometriosis is a common and recurring gynecologic disease which have afflicting females of reproductive age. We investigated the efficacy of long-term, post-operative use of dienogest for ovarian endometrioma. METHODS: We studied 203 patients who had undergone laparoscopic or robotic surgery for ovarian endometrioma, and were administrated dienogest 2 mg/day beginning in July of 2013, and continuing. We evaluated side effects of dienogest and ultrasonography was performed every 6 months to detect potential recurrence of endometrioma (2 cm) in these post-surgical patients. RESULTS: The follow-up observation periods were 30.2±20.9 months from surgery. The mean age was 34.1±7.2 years old. The mean diameter of pre-operative endometrioma was 5.6±3.0 cm2. One hundred eighty-two (89.7%) women received dienogest continuously for 12.0±7.1 months. Of the subjects, 21 (10.3%) patients discontinued dienogest at 2.4±1.0 months. The most common side effect when dienogest was discontinued was abnormal uterine bleeding. The occurrence rate of vaginal bleeding was 15.8%, a number which did not differ significantly in patients with/without post-operative gonadotropin releasing hormone agonist administration. The other side effects were gastrointestinal trouble including constipation, acne, headache, depression, hot flush, weight gain, and edema. However, no serious adverse events or side effects were documented and recurrent endometriomas were diagnosed in 3 patients (1.5%). CONCLUSION: The data indicates that dienogest was both tolerable and safe for long-term use as prophylaxis in an effort to obviate the recurrence of ovarian endometrioma post-operatively, as well as potential need for surgical re-intervention.
RESUMEN
OBJECTIVE: Adenomyosis and endometriosis are relatively common gynecological diseases that exhibit many common features. This study identified gynecological and non-gynecological diseases that exhibited comorbidity with adenomyosis and endometriosis in Korean women. METHODS: We used Health Insurance Review and Assessment data from 2009 to 2011 and searched for adenomyosis and endometriosis (coded as N80.1 and D25 in International Classification of Disease, 10th revision [ICD-10], respectively). We selected records from patients who had independent disease occurrences in each year, and comorbidities were estimated using Fisher's exact test. We computed each year's similarities and combined 3 years' results using Fisher's P-value summation method. RESULTS: A total of 61,516 patients' data were collected during the study period. The prevalence of adenomyosis and endometriosis were similar each year: 12.4% and 9.3% in 2009, 12.5% and 9.4% in 2010 and 13.3% and 9.1% in 2011, respectively. Meta-analysis revealed that 31 ICD-10 codes were significantly related with adenomyosis, and 44 ICD-10 codes were related with endometriosis. Gynecological diseases, such as leiomyoma and benign ovarian tumor, were significantly related to adenomyosis and endometriosis. Non-gynecological diseases, such as anemia and hypercholesterolemia, were also related to adenomyosis and endometriosis. CONCLUSION: We must monitor for the presence of gynecological and non-gynecological diseases with co-morbidities during evaluations and follow-up of patients with adenomyosis or endometriosis.
