Abstract
Volumetric laser endomicroscopy (VLE) uses optical coherence tomography (OCT) for real-time, microscopic cross-sectional imaging. A US-based multi-center registry was constructed to prospectively collect data on patients undergoing upper endoscopy during which a VLE scan was performed. The objective of this registry was to determine usage patterns of VLE in clinical practice and to estimate quantitative and qualitative performance metrics as they are applied to Barrett's esophagus (BE) management. All procedures utilized the NvisionVLE Imaging System (NinePoint Medical, Bedford, MA) which was used by investigators to identify the tissue types present, along with focal areas of concern. Following the VLE procedure, investigators were asked to answer six key questions regarding how VLE impacted each case. Statistical analyses including neoplasia diagnostic yield improvement using VLE was performed. One thousand patients were enrolled across 18 US trial sites from August 2014 through April 2016. In patients with previously diagnosed or suspected BE (894/1000), investigators used VLE and identified areas of concern not seen on white light endoscopy (WLE) in 59% of the procedures. VLE imaging also guided tissue acquisition and treatment in 71% and 54% of procedures, respectively. VLE as an adjunct modality improved the neoplasia diagnostic yield by 55% beyond the standard of care practice. In patients with no prior history of therapy, and without visual findings from other technologies, VLE-guided tissue acquisition increased neoplasia detection over random biopsies by 700%. Registry investigators reported that VLE improved the BE management process when used as an adjunct tissue acquisition and treatment guidance tool. The ability of VLE to image large segments of the esophagus with microscopic cross-sectional detail may provide additional benefits including higher yield biopsies and more efficient tissue acquisition.

Abstract
Although laparoscopic donor hepatectomy is increasingly common, few centers with substantial experience have reported the results of pure laparoscopic donor right hepatectomy (PLDRH). Here, we report the experiences of 60 consecutive liver donors undergoing pure laparoscopic donor hepatectomy (PLDH), with most undergoing right hepatectomy. None of the 60 donors who underwent PLDH had intraoperative complications and none required transfusions, reoperation, or conversion to open hepatectomy. Forty-five donors who underwent PLDRH between November 2015 and December 2016 were compared with 42 who underwent conventional donor right hepatectomy (CDRH) between May 2013 and February 2014. The total operation time was longer (330.7 vs 280.0 minutes; P < .001) and the percentage with multiple bile duct openings was higher (53.3% vs 26.2%; P = .010) in the PLDRH group. However, the length of postoperative hospital stay (8.4 vs 8.2 days; P = .495) and rate of complications (11.9% vs 8.9%; P = .733) and re-hospitalizations (4.8% vs 4.4%; P = 1.000) were similar in both groups. PLDH, including PLDRH, is feasible when performed by a highly experienced surgeon and transplant team. Further evaluation, including long-term results, may support these preliminary findings of comparative outcomes for donors undergoing PLDRH and CDRH.

Abstract
Essentials Data on venous thromboembolism (VTE) after L-asparaginase (L-asp) in Asian lymphoma are scarce. This is a population-based study in Asian patients with lymphoid disease and L-asp-related VTE. The overall incidence of L-asp-associated VTE was similar to reports on Caucasians. This first and largest study in Asians shows that mainly adult patients are at risk of thrombosis. SUMMARY Background L-asparaginase (L-asp)-associated venous thromboembolism (VTE) is a serious adverse complication associated with acute lymphoblastic leukemia (ALL) and lymphoma treatment. The incidence rate of L-asp-related VTE in Asian cancer patients is not well known. Methods We performed a population-based study between 2009 and 2013 using claim databases, including both diagnostic and medication codes, such as anti-cancer treatment with L-asp and VTE diagnoses from the starting date until 3 months after cessation of L-asp. Results A total of 3286 patients were prescribed L-asp treatment for any type of lymphoid malignancy including ALL and lymphoma; 116 patients (3.5%) experienced VTE. The most common site of thrombosis was the upper extremities (34.5%). Cerebral vein thrombosis (1.7%) occurred in two pediatric patients; 2.4% (43/1795) of pediatric patients and 4.9% (72/1486) of adult patients suffered from VTE, respectively; 2.7% (56/2064) of ALL and 4.9% (59/1217) of lymphoma patients were diagnosed with VTE after L-asp exposure. After univariate analysis, both the diagnosis of lymphoma (vs. ALL) and being an adult patient (vs. pediatric patient) were risk factors for VTE occurrence. However, after multivariate analysis, only age > 18 remained a risk factor for VTE (odds ratio, 1.79; 95% confidence interval, 1.14-2.81). Conclusions This is the first and largest population-based study in Asian patients with lymphoid malignancies treated with L-asp demonstrating that adult patients are at elevated risk of thrombosis after L-asp exposure. The overall incidence of L-asp-related VTE amongst these patients was similar to that in Caucasian populations.

Abstract
BACKGROUND T he most commonly used methods for the cryopreservation of oocytes and embryos are vitrification and slow freezing. OBJECTIVE The aim of this study was to to investigate whether there are differences in survival, in vitro maturation (IVM), and fertilization rates between cryopreserved immature oocytes, especially germinal vesicle (GV)-stage human oocytes, following vitrification and slow freezing. MATERIALS AND METHODS A literature search was performed using the MEDLINE, Cochrane Central Register of Controlled Trials, and Embase databases. A total of three studies were included in the Bayesian meta-analysis. RESULTS There was no difference in survival rates between vitrification and slow freezing. Additionally, there was no difference in IVM rates and fertilization rates between vitrification and slow freezing. CONCLUSION The superiority of vitrification over slow freezing for cryopreservation of GV-stage human oocytes remains unclear. Additional studies on cytoarchitecture and modification of the cryopreservation protocol are essential to achieve strong conclusions.

Abstract
OBJECTIVES Serous cystic neoplasm (SCN) is a cystic neoplasm of the pancreas whose natural history is poorly known. The purpose of the study was to attempt to describe the natural history of SCN, including the specific mortality. DESIGN Retrospective multinational study including SCN diagnosed between 1990 and 2014. RESULTS 2622 patients were included. Seventy-four per cent were women, and median age at diagnosis was 58 years (16-99). Patients presented with non-specific abdominal pain (27%), pancreaticobiliary symptoms (9%), diabetes mellitus (5%), other symptoms (4%) and/or were asymptomatic (61%). Fifty-two per cent of patients were operated on during the first year after diagnosis (median size: 40 mm (2-200)), 9% had resection beyond 1 year of follow-up (3 years (1-20), size at diagnosis: 25 mm (4-140)) and 39% had no surgery (3.6 years (1-23), 25.5 mm (1-200)). Surgical indications were (not exclusive) uncertain diagnosis (60%), symptoms (23%), size increase (12%), large size (6%) and adjacent organ compression (5%). In patients followed beyond 1 year (n=1271), size increased in 37% (growth rate: 4 mm/year), was stable in 57% and decreased in 6%. Three serous cystadenocarcinomas were recorded. Postoperative mortality was 0.6% (n=10), and SCN's related mortality was 0.1% (n=1). CONCLUSIONS After a 3-year follow-up, clinical relevant symptoms occurred in a very small proportion of patients and size slowly increased in less than half. Surgical treatment should be proposed only for diagnosis remaining uncertain after complete workup, significant and related symptoms or exceptionally when exists concern with malignancy. This study supports an initial conservative management in the majority of patients with SCN. TRIAL REGISTRATION NUMBER IRB 00006477.

Abstract
BACKGROUND Direct oral anticoagulants have been evaluated for their efficacy and safety in the treatment of venous thromboembolism (VTE), which comprises deep vein thrombosis and pulmonary embolism. The randomized, double-blind Hokusai-VTE trial demonstrated that 60 mg of edoxaban once daily following initial heparin treatment is non-inferior to heparin overlapped with and followed by warfarin for the treatment of VTE, and is associated with significantly fewer bleeding events. OBJECTIVES To assess the efficacy and safety of edoxaban versus warfarin among East Asian patients enrolled in the Hokusai-VTE trial. PATIENTS/METHODS The Hokusai-VTE trial enrolled 8292 patients from 439 centers worldwide, including 1109 patients from Japan, China, Korea, and Taiwan. The primary efficacy and safety outcomes were symptomatic recurrent VTE and clinically relevant bleeding, respectively. RESULTS In the overall East Asian population, the primary efficacy outcome of symptomatic recurrent VTE occurred in 16 of 563 (2.8%) patients in the edoxaban group versus 24 of 538 (4.5%) patients in the warfarin group (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.34-1.19; P = 0.1601). The primary safety outcome of clinically relevant bleeding occurred in 56 of 563 (9.9%) patients in the edoxaban group versus 93 of 538 (17.3%) patients in the warfarin group (HR 0.56; 95% CI 0.40-0.78; P < 0.001). CONCLUSIONS Edoxaban is an effective and safer alternative to warfarin in East Asian patients with acute VTE who require anticoagulant therapy, consistent with overall study findings from the Hokusai-VTE trial.

Abstract
BACKGROUND Data on the incidence of venous thromboembolism (VTE) following major surgery in Asian populations are limited. METHODS Using the Korean Health Insurance Review and Assessment Service database, we performed a nationwide population-based epidemiologic study to estimate the incidence of VTE after major orthopedic, cancer, and benign surgeries. VTE cases were identified from all patients undergoing major surgery between 2007 and 2011 using both diagnostic and drug codes as treatment evidence of VTE within 5 weeks of surgery. We also calculated the relative risk of VTE in major orthopedic and cancer surgery compared to benign surgery. RESULTS The overall rates of postoperative VTE were 1.24%, 0.67%, and 0.05% for major orthopedic, cancer, and benign surgeries, respectively. Hip fracture (1.60%) and colorectal cancer surgeries (1.67%) were associated with the highest rates of VTE, and the rates steadily increased during the study period. Advanced age, female sex, and general anesthesia were independent risk factors for VTE. Patients undergoing surgery for colorectal, pancreatic, ovarian, and esophageal cancer, and major orthopedic surgery had a > 20-fold higher risk of VTE than those undergoing benign surgery. CONCLUSIONS This is the largest epidemiologic study to investigate the incidence of VTE after major surgery in Asia, demonstrating that the rates of postoperative VTE are lower than in Caucasian populations. This study contributes to a better understanding of the differences in postoperative VTE development between Korean and Caucasian populations; the data also suggest that perioperative prophylactic strategies in Asians should be based on studies of such populations.
