Objective
To determine the effect of frailty on patient outcomes including any complication, Clavien-Dindo IV (CDIV) (intensive care unit-level) complications, and 30-day mortality for robotic-assisted radical prostatectomies (RARP) patients in comparison to other predictive indices using the modified frailty index (mFI).Material and methods
Patients undergoing RARP from 2008 to 2014 for a prostate cancer–related diagnosis were queried using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. The mFI was developed using the Canadian Study of Health and Aging Frailty Index as a model. The mFI was compared with other associative indices such as the American Society of Anesthesiology (ASA) classification and the Charlson comorbidity index (CCI). Rates of CDIV complications and 30-day mortality were analyzed based on mFI score using SAS version 9.22.Results
A total of 23,104 patients undergoing RARP were queried. RARP patients with the highest frailty score (≥3) had an adjusted odds for CDIV complications of Odds ratio of 12.107 (CI: 2.800–52.351, P< 0.005) in comparison with nonfrail RARP patients. These odds were higher than the ASA and Charlson comorbidity index. Additionally, a variable combining mFI and ASA had fair sensitivity and specificity for predicting 30-day mortality in RARP patients (C-statistic = 0.7097, P<0.0001).Conclusion
Increasing mFI scores are associated with worsening outcomes for patients undergoing RARP. A combined mFI and ASA variable can be used to predict 30-day mortality for RARP patients better than mFI or ASA alone. 相似文献2.

Purpose
To compare the duration of sick leave in patients with localized prostate cancer after robot-assisted radical prostatectomy (RARP) and open retropubic RP (ORP) at a German high-volume prostate cancer center.Methods
The data of 1,415 patients treated with RP at Martini Klinik, Prostate Cancer Center between 2012 and 2016 were, retrospectively, analyzed. Information on employment status, monthly revenues and days of work missed due to sickness were assessed via online questionnaire. Additional data were retrieved from our institutional database.Medians and interquartile ranges (IQR) were reported for continuous data. Cox proportional hazard analysis was performed to compare both surgical techniques for return to work time after RP.Results
Median time elapsed between surgery and return to work comprised 42 days in patients undergoing RARP (IQR: 21–70) and ORP (IQR: 28–84, P = 0.05). In Cox regression analysis, surgical approach showed no impact on return to work time (RARP vs. ORP hazard ratio = 1, 95% CI: 0.91–1.16, P = 0.69). Return to work time was significantly associated with employment status, physical workload and monthly income (all P<0.001). Limitation of this study is the nonrandomized design in a single-center.Conclusions
As the surgical approach did not show any influence on the number of days missed from work in patients undergoing RP, no superiority of either RARP or ORP could be identified for return to work time in a German cohort. Both surgical approaches are safe options usually allowing the patients to resume normal activities including work after an appropriate convalescence period. 相似文献3.

Background
Despite a lack of demonstrated patient benefit, many insurance providers mandate a physician-supervised diet before financial coverage for bariatric surgery.Objectives
To compare weight loss between patients with versus without insurance mandating a preoperative diet.Setting
University hospital, United States.Methods
Retrospective study of all patients who underwent laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy over a 5-year period, stratified based on whether an insurance-mandated physician-supervised diet was required. Weight loss outcomes at 6, 12, and 24 months postoperation were compared. Linear mixed-models and backward-stepwise selection were used. P<0.05 was considered significant.Results
Of 284 patients, 225 (79%) were required and 59 (21%) were not required to complete a preoperative diet by their insurance provider. Patients without the requirement had a shorter time to operation from initial consultation (P = .04), were older (P<.01), and were more likely to have government-sponsored insurance (P<.01). There was no difference in preoperative weight or body mass index or co-morbidities. In unadjusted models, percent excess weight loss was superior in the group without an insurance-mandated diet at 12 (P = .050) and 24 (P = .045) months. In adjusted analyses, this group also had greater percent excess weight loss at 6 (P<.001), 12 (P<.001), and 24 (P<.001) months; percent total weight loss at 24 months (P = .004); and change in body mass index at 6 (P = .032) and 24 (P = .007) months. There was no difference in length of stay or complication rates.Conclusions
Insurance-mandated preoperative diets delay treatment and may lead to inferior weight loss. 相似文献4.

Background
Global experiences in general surgery suggest that previous abdominal surgery may negatively influence different aspects of perioperative care. As the incidence of bariatric procedures has recently increased, it is essential to assess such correlations in bariatric surgery.Objectives
To assess whether previous abdominal surgery influences the course and outcomes of laparoscopic bariatric surgery.Setting
Seven referral bariatric centers in Poland.Methods
We conducted a retrospective analysis of 2413 patients; 1706 patients who underwent laparoscopic sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) matched the inclusion criteria. Patients with no history of abdominal surgery were included as group 1, while those who had undergone at least 1 abdominal surgery were included as group 2.Results
Group 2 had a significantly prolonged median operation time for RYGB (P = .012), and the longest operation time was observed in patients who had previously undergone surgeries in both the upper and lower abdomen (P = .002). Such a correlation was not found in SG cases (P = .396). Groups 1 and 2 had similar rates of intraoperative adverse events and postoperative complications (P = .562 and P = .466, respectively). Group 2 had a longer median duration of hospitalization than group 1 (P = .034), while the readmission rate was similar between groups (P = .079). There was no significant difference between groups regarding the influence of the long-term effects of bariatric treatment on weight loss (percentage of follow-up was 55%).Conclusions
Previous abdominal surgery prolongs the operative time of RYGB and the duration of postoperative hospitalization, but does not affect the long-term outcomes of bariatric treatment. 相似文献5.

Background
Laparoscopic sleeve gastrectomy (LSG) has become a popular procedure for treatment of obesity, but it is still undecided whether resected gastric volume (RGV) is related to weight loss after LSG.Objective
The aim of this study was to investigate the influence of RGV and other factors on weight loss at 1 year after LSG in a Chinese population.Setting
University Hospital, China.Methods
A total of 53 patients who underwent LSG between August 2015 and July 2016 were enrolled. The LSG procedure and RGV measurement were performed using standardized techniques. Patients were followed-up every 3 months in the first year and 6 monthly after that. Correlations between the percentage of excess weight loss at 1 year (%EWL-1 yr) and RGV and other parameters were evaluated.Results
All patients completed at least 1 year of follow-up. No major complications or cases of underweight were seen. Mean body mass index (BMI) at 1 year after LSG was significantly lower than the baseline BMI (31.1 ± 3.8 kg/m2 versus 39.0 ± 6.6 kg/m2; P<.001). Mean %EWL-1 yr was 58.8%, and mean RGV was 862.6 ± 209.5 mL. No correlation was observed between %EWL-1 yr and RGV (r = ?0.071; P = .613). The %EWL-1 yr was correlated with preoperative weight, BMI, RGV/weight, and RGV/BMI. RGV was positively correlated with preoperative weight and BMI. Patients who achieved satisfactory weight loss (%EWL ≥50%) had significantly lower baseline BMI, and higher RGV/weight and RGV/BMI, than those who had inadequate weight loss. However, RGV was not significantly different between the 2 groups.Conclusions
Weight loss effect at 1 year after LSG was not associated with RGV in this Chinese population. RGV was influenced by the weight and BMI. 相似文献6.

Background
Warfarin dosing after bariatric surgery may be influenced by alterations in gastrointestinal pH, transit time, absorptive surface area, gut microbiota, food intake, and adipose tissue.Objectives
The aim of this study was to describe trends in warfarin dosing after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG).Setting
Single academic center.Methods
All patients chronically on warfarin anticoagulation before RYGB or SG were retrospectively identified. Indications for anticoagulation, history of bleeding or thrombotic events, perioperative complications, and warfarin dosing were collected.Results
Fifty-three patients (RYGB n = 31, SG n = 22) on chronic warfarin therapy were identified (56.6% female, mean 54.4 ± 11.7 yr of age). Of this cohort, 34.0% had prior venous thromboembolic events, 43.4% had atrial fibrillation, and 5.7% had mechanical cardiac valves. Preoperatively, the average daily dose of warfarin was similar in the RYGB group (8.3 ± 4.1 mg) and SG group (6.9 ± 2.8 mg). One month after surgery, mean daily dose of warfarin was reduced 24.1% in the RYGB group (P<.001) and 23.2% in the SG group (P = .002). At 12 months postoperatively, the required daily warfarin dose compared with baseline remained statistically different (RYGB: 6.8 ± 3.8 mg; SG: 6.1 ± 2.0 mg).Conclusions
The warfarin dose is expected to be decreased by approximately 25% from preoperative levels after both RYGB and SG. Lower dose requirement within the first month after bariatric surgery is followed by a trend toward increased warfarin dose requirements, but remain less than baseline. Because dose requirements change constantly over time, frequent postoperative monitoring of the international normalized ratio is recommended. 相似文献7.

Background
Preoperative immobility in general surgery patients has been associated with an increased risk of postoperative complications. It is unknown if immobility affects bariatric surgery outcomes.Objectives
The aim of this study was to determine the impact of immobility on 30-day postoperative bariatric surgery outcomes.Setting
This study took place at a university hospital in the United States.Methods
The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. Preoperative immobility was defined as limited ambulation most or all the time. Logistic regression analysis was performed to determine if immobile patients are at increased risk (odds ratio [OR]) for 30-day complications.Results
There were 148,710 primary minimally invasive bariatric procedures in 2015. Immobile patients had an increased risk of mortality (OR 4.59, P<.001) and greater operative times, length of stay, reoperation rates, and readmissions. Immobile patients had a greater risk of multiple complications, including acute renal failure (OR 6.42, P<.001), pulmonary embolism (OR 2.44, P = .01), cardiac arrest (OR 2.81, P = .05), and septic shock (OR 2.78, P = .02). Regardless of procedure type, immobile patients had a higher incidence of perioperative morbidity compared with ambulatory patients.Conclusions
This study is the first to specifically assess the impact of immobility on 30-day bariatric surgery outcomes. Immobile patients have a significantly increased risk of morbidity and mortality. This study provides an opportunity for the development of multiple quality initiatives to improve the safety and perioperative complication profile for immobile patients undergoing bariatric surgery. 相似文献8.

Background
The impact of omega-loop gastric bypass (OLGB) on weight loss and liver enzymes remains inconclusive.Objective
The aim of this study was to compare the impact of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and OLGB on weight loss and liver enzyme levels.Setting
National Bariatric Surgery Registry.Methods
The study included 10,675 cases of SG, 1590 cases of RYGB, and 469 cases of OLGB that had available baseline and 1-year (12 ± 2 mo) follow-up data.Results
The highest percentage of excess weight loss was achieved by the OLGB group (84.5% ± 26.7%), followed by the SG (78.5% ± 26.0%) and RYGB (72.0% ± 26.5%) groups (P<.05). The data show that 10% of OLGB cases, 5.2% of RYGB cases, and 1.9% of SG cases (P<.001) had increases in alanine aminotransferase levels, from a normal baseline mean of 23.9 ± 7.5 U/L to an abnormal mean of 64.8.7 ± 66.0 U/L, at follow-up. Similar trends were observed for aspartate aminotransferase and alkaline phosphatase. A regression analysis showed that OLGB was a predictive risk factor for normal baseline alanine aminotransferase levels becoming abnormal postoperatively compared with SG (odds ratio [OR] = 5.65) or RYGB (OR = 2.08) (P<.001). Similarly, OLGB was a predictive risk factor for baseline aspartate aminotransferase and alkaline phosphatase levels becoming abnormal postoperatively. Female sex was the only other meaningful predictive risk of alanine aminotransferase (OR = 2.45) and aspartate aminotransferase (OR = 1.82) becoming abnormal postoperatively.Conclusion
This study confirmed the strengths of OLGB weight loss outcomes but also demonstrated its negative impact on liver enzymes. Thus, patients and caregivers should be informed of the risks, and close follow-up is warranted. 相似文献9.

Background
Acetyl-CoA synthetase 2 (ACSS2) is highly expressed in various cancers, whereas ACSS2 expression and function in renal cell carcinoma (RCC) are unknown.Methods
We investigated ACSS2 expression in 198 human RCC tissues using immunohistochemistry, and analyzed its clinicopathological correlation and prognostic relevance. Overexpression and knockdown of ACSS2 were used to investigate the proliferation, migration and invasion of human RCC 786-O, 769-P, and ACHN cell lines.Results
High-ACSS2 expression was associated with advanced T stage (P = 0.008), advanced tumor-node-metastasis stage (P = 0.015) and high University of California, Los Angeles, Integrated Staging System score category (P = 0.009). Multivariate analysis identified high-ACSS2 expression as a poor prognostic factor for recurrence-free survival (hazard ratio [HR] = 1.83, P = 0.038) and overall survival (HR = 1.60, P = 0.043). Cell-based functional assays showed that ACSS2 knockdown inhibited RCC cell growth, migration, and invasion, whereas overexpression of ACSS2 enhanced these effects. ACSS2 silencing inhibited PI3K/AKT signaling pathway.Conclusion
ACSS2 may increase tumor progression and aggressive behavior and be an independent prognostic factor in RCC. 相似文献10.

Background
Identifying the optimal surgical approach for patients with localized prostate cancer (PCa) managed in the community setting remains controversial due to the lack of robust, prospective data.Objective
To assess surgical outcomes and changes in urinary and sexual quality of life (QOL) over time in patients undergoing radical prostatectomy (RP).Design, setting, and participants
Our study included patients enrolled in Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE), a large, prospective, mostly community-based, nationwide PCa registry, who underwent RP between 2004 and 2016.Intervention
Open (ORP) versus robot-assisted radical prostatectomy (RARP) for localized PCa.Outcome measurements and statistical analysis
Demographic and clinicopathologic data and surgical outcomes were compared between ORP and RARP. Self-reported, validated questionnaires (scaled 0–100 with higher numbers indicating better function) were used to evaluate urinary and sexual QOL at different time points. Repeated measures mixed-models assessed changes in function and bother over time in each domain.Results and limitations
Among 1892 men (n = 1137 ORP; n = 755 RARP), Cancer of the Prostate Risk Assessment score, Gleason grade at biopsy and RP, and pT-stage were lower in ORP patients (all p < 0.01). Men undergoing RARP had comparable surgical margin rates, lymph node yields, and biochemical recurrence rates. In a subset analysis with 1451 men reporting baseline and follow-up QOL data, ORP patients reported superior scores in urinary incontinence (ORP mean ± standard deviation 69 ± 26 vs RARP 62 ± 27) and bother (ORP 75 ± 29 vs RARP 68 ± 28, both p < 0.01) only in the 1st yr after RP. Differences in sexual outcomes did not differ between groups, nor did any QOL scores beyond 1 yr. Limitations include a decrease in the rate of questionnaire response during follow-up, potential selection biases in terms of patient assignment to ORP versus RARP and survey completion rates, and the fact that RARP cases likely included the initial learning curve for the CaPSURE surgeons.Conclusions
Most patients experienced changes in urinary and sexual QOL in the 1st 3 yr following RP. The pattern of recovery over time was similar between ORP and RARP groups. Patients should not expect different oncologic or QOL outcomes based on surgical approach.Patient summary
Aside from a small, early, and temporary advantage in terms of urinary incontinence and bother favoring open surgery, minimal differences in outcomes are observed when comparing men who undergo open versus robot-assisted prostatectomy in the community setting. 相似文献11.

Background
While hypoglycemia during an oral glucose tolerance test (OGTT) has been shown to occur in a considerable portion of nonpregnant post–bariatric surgery (BS) patients, its incidence among pregnant post-BS patients evaluated for gestational diabetes has only been sparsely studied.Objectives
We investigated OGTT results and pregnancy outcomes in pregnant women who underwent 3 types of bariatric procedures before pregnancy.Setting
A university hospital.Methods
From medical records, data were collected on glucose measurements during a 100-g, 3-hour OGTT, as well as maternal and fetal outcomes.Results
Of 119 post-BS pregnant patients included in the study, 55 underwent laparoscopic sleeve gastrectomy, 34 laparoscopic adjustable gastric banding, and 30 laparoscopic Roux-en-Y gastric bypass surgery. Hypoglycemia (<55 mg/dL) was encountered in 59 (49.6%) patients during the OGTT. Among them, the nadir plasma glucose levels occurred 2 hours after glucose ingestion in 25 (42.4%) and after 3 hours in 34 (57.6%), with a median value of 47 (44–52) mg/dL. The risk of hypoglycemia was higher among women with prior laparoscopic Roux-en-Y gastric bypass surgery (83.3%) than among those with prior laparoscopic sleeve gastrectomy (54.5%; P = .009) or laparoscopic adjustable gastric banding (11.8%; P<.0001). Time from surgery to conception was significantly shorter among women with evidence of hypoglycemia during OGTT (median 711 versus 1246 days, P = .002). Compared with patients without evidence of hypoglycemia, patients who experienced hypoglycemia had lower rates of gestational diabetes (P = .03) but higher proportions of low birth weight (P = .01) and small for gestational age infants (P = .03).Conclusions
Because hypoglycemia is common during OGTT among post-BS parturients, other diagnostic methods should be considered in this setting. The association found between hypoglycemia and poor fetal growth warrants investigation as to whether interventions to prevent hypoglycemia will improve fetal outcome. 相似文献12.

Background
Hypoglycemia after bariatric surgery is an increasingly recognized metabolic complication associated with exaggerated secretion of insulin and gut hormones.Objective
We sought to determine the incidence of hypoglycemic symptoms (hypo-sx) after bariatric surgery and characteristics of those affected compared with those unaffected.Setting
University hospital.Methods
We collected retrospective survey data from the patients who underwent bariatric surgery at a single center. Based on number and severity of postprandial hypo-sx in Edinburgh hypoglycemia questionnaire postoperatively, patients without preoperative hypo-sx were grouped into high versus low suspicion for hypoglycemia. We used multivariable logistic regression to examine potential baseline and operative risk factors for the development of hypo-sx after surgery.Results
Among the 1119 patients who had undergone bariatric surgery who received the questionnaire, 464 (40.6%) responded. Among the 341 respondents without preexisting hypo-sx, 29% (n = 99) had new-onset hypo-sx, and most were severe cases (n = 92) with neuroglycopenic symptoms. Compared with the low suspicion group, the high suspicion group consisted of more female patients, younger patients, patients without diabetes, and those who underwent Roux-en-Y gastric bypass with a longer time since surgery and more weight loss. In multivariate analysis, factors independently associated with incidence of hypo-sx after bariatric surgery were female sex (P = .003), Roux-en-Y gastric bypass (P = .001), and absence of preexisting diabetes (P = .011).Conclusions
New onset postprandial hypoglycemic symptoms after bariatric surgery are common, affecting up to a third of those who underwent bariatric surgery. Many affected individuals reported neuroglycopenic symptoms and were more likely to be female and nondiabetic and to have undergone Roux-en-Y gastric bypass. 相似文献13.

Background
Bariatric surgery is associated with increased thromboembolic risk, which may extend well beyond hospital stay. The hemostatic mechanisms implicated in this risk are not well established.Objectives
We aimed to determine the dynamics of hemostatic changes and procoagulant potential among patients undergoing laparoscopic sleeve gastrectomy, during both the early and late postoperative periods.Setting
A university hospital.Methods
Patients who underwent laparoscopic sleeve gastrectomy were recruited consecutively to this study. Blood samples were taken preoperatively, before discharge (postoperative day [POD] 3), and at the first follow-up visit (POD10). All samples were tested for complete blood count, C-reactive protein, von Willebrand factor, factor VIII, fibrinogen, and thrombin generation.Results
The median preoperative body mass index of the 26 participants was 41.3 (38.7–43.3) kg/m2. Compared with preoperative evaluation, fibrinogen, von Willebrand factor antigen and activity, and factor VIII levels were significantly higher at POD3 and POD10 (P<.0001 for all comparisons). Peak thrombin levels and endogenous thrombin potential (ETP) were higher at POD3 (P = .005 for both comparisons) and POD10 (P = .0009 and<.0001) compared with baseline. ETP and peak thrombin, as well as fibrinogen, von Willebrand factor, and factor VIII levels, were comparable between POD3 and POD10. Multivariate analysis showed that the only predictor of postoperative ETP was the preoperative ETP level (β = .55, P = .007).Conclusions
As determined by thrombin generation, laparoscopic sleeve gastrectomy was associated with hypercoagulability, which persisted during POD10. This finding suggests a possible benefit of extended thromboprophylaxis. Nevertheless, our results should be interpreted with caution due to the lack of a control group. 相似文献14.

Background
Obesity has been associated with daytime urinary incontinence (UI), likely due to increased intra-abdominal pressure.Objectives
To assess incontinence symptoms in severely obese adolescents before and 3 years after bariatric surgery.Setting
Tertiary care pediatric hospitals in the United States.Methods
The Teen-Longitudinal Assessment of Bariatric Surgery is a prospective, multicenter study designed to evaluate efficacy and safety of bariatric surgery in adolescents. Patients<19 years of age undergoing bariatric surgery at 5 centers between 2007 and 2012 were enrolled. Trained study staff collected baseline and postoperative anthropometric and clinical data. Presence and severity of UI were determined by standardized interview.Results
A total of 242 patients (76% female) were evaluated at baseline. The mean age was 17.1 years at baseline, and 72% were of white race. The preoperative median body mass index was 50.5 kg/m2. At baseline, 18% of females and 7% of males reported UI. Prediction analysis at baseline indicated that females, white race, and increasing body mass index had greater odds for UI. UI prevalence in females and males decreased to 7% and 0%, respectively, at 6 months after surgery (P<.01) and remained stable out to 36 months postoperatively. Furthermore, older patients were less likely to achieve 3-year UI remission or improvement.Conclusions
In adolescents undergoing bariatric surgery, UI was more common in females than in males. Incontinence status significantly improved by 6 months and was durable to 3 years after surgery, suggesting that bariatric surgery favorably affects anatomic or physiologic mechanisms of bladder control in both males and females. 相似文献15.

Background
Laparoscopic sleeve gastrectomy (LSG) can result in de novo and worsen preexisting gastroesophageal reflux disease (GERD). Post-LSG patients with GERD refractory to proton pump inhibitors (PPI) usually undergo more invasive, anatomy-altering Roux-en-Y gastric bypass surgery. Lower esophageal sphincter (LES) electrical stimulation (ES) preserves the anatomy and has been shown to improve outcomes in GERD patients.Objective
To evaluate the safety and efficacy of LES-ES in post-LSG patients with GERD not controlled with maximal PPI therapy.Setting
Prospective, international, multicenter registry.Methods
Patients with LSG-associated GERD partially responsive to PPI underwent LES-ES. GERD outcomes pre- and poststimulation were evaluated based on quality of life, esophageal acid exposure (after 6–12 mo), and PPI use.Results
Seventeen patients (11 female, 65%), treated at 6 centers between May 2014 and October, 2016 with a median follow-up of 12 months (range 6–24), received LES-ES. Median age was 48.6 years (interquartile range, 40.5–56), median body mass index 31.7 kg/m2 (27.9–39.3). All patients were on at least daily PPI preoperatively; at last follow-up, 7 (41%) were completely off PPI, 5 (29%) took PPI on an intermittent basis, and 5 (29%) were on single-dose PPI. Median GERD–health-related quality of life scores improved from 34 (on-PPI, 25–41) at baseline to 9 (6–13) at last follow-up (off-PPI, P<.001). Percentage of time with esophageal pH<4 improved from 13.2% (3.7–30.7) to 5.8% (1.1–54.4), P = .01.Conclusion
LES-ES in post-LSG patients suffering from symptomatic, PPI-refractory GERD resulted in significant improvement of GERD-symptoms, esophageal acid exposure, and need for PPI. Preserving the post-LSG anatomy, it offers a valid option for patients unable or unwilling to undergo Roux-en-Y gastric bypass surgery. 相似文献16.

Background
There are currently no methods in clinical use that can detect early systemic dissemination of urothelial tumor cells.Objective
To evaluate measurement of circulating tumor cells (CTCs) as a biomarker for disseminated disease in patients with advanced bladder cancer.Design, setting, and participants
Between March 2013 and October 2015, 88 patients were prospectively included in the study: 78 were scheduled for radical cystectomy (RC) ± perioperative chemotherapy and 10 treated with palliative chemotherapy. The CellSearch CTC test was further assessed in this context by investigating expression of epithelial cell adhesion molecule (EpCAM) in primary tumors obtained at cystectomy from an independent cohort of 409 patients.Outcome measurements and statistical analysis
Presence of CTCs was tested for association with tumor stage, lymph node metastases, metastatic disease on [18 F]-fluorodeoxyglucose-positron emission tomography (FDG-PET), and cancer-specific and progression-free survival.Results
CTCs were detected in 17/88 patients (19%). In 61 patients who underwent FDG-PET-computed tomography (CT), a statistically significant association with presence of CTCs was found for radiological metastatic disease but not for normal PET-CT results (12/35 [34%] vs. 2/26 [8%], P = 0.014). After a median follow-up time of 16.5 months (95% CI: 9.6–21.4), presence of CTCs was associated with an increased risk of progression among patients treated with RC with or without perioperative chemotherapy (n = 75, P = 0.049). A multivariate analysis adjusted for clinical tumor stage, clinical lymph node status, and age showed that CTCs were an independent marker of progression (n = 75; hazard ratio = 2.78; 95% CI: 1.005–7.69; P = 0.049) but not of cancer-specific death (P = 0.596). In 409 cystectomised patients, more than 392 (96%) of the bladder tumors expressed EpCAM.Conclusions
CTCs were present in 19% of patients with advanced urothelial tumors and were associated with metastatic disease on FDG-PET-CT and with increased risk of disease progression after RC. A significant portion of urothelial cancer cells do express EpCAM and can thus be identified using EpCAM-antigen–based CTC detection methods. 相似文献17.

The current popularity of metabolic surgery has led to increasing attention to long-term nutritional complications.Objective
The purpose of this retrospective study is to accurately define the long-term incidence of clinically significant anemia after Roux-en-Y gastric bypass (RYGB) and to identify factors that contribute to increased risk.Methods
The study cohort consisted of 2116 patients who underwent RYGB with necessary laboratory information available, and with longitudinal follow-up available (mean 5.3 ± 3.3 yr). A concurrent cohort of nonoperated patients matched for age, sex, body mass index, and baseline hemoglobin was identified (N = 1126). The RYGB and control cohorts were followed longitudinally to estimate the percent that develop mild, moderate, or severe anemia using Kaplan-Meier analysis. Predictors of severe anemia within the RYGB cohort were identified using Cox regression.Results
The percent developing postRYGB mild, moderate, and severe anemia was 27%, 9%, and 2% at 1 year postRYGB and increased to 68%, 33%, and 11% at 5 years postRYGB. As compared with the nonoperated control cohort, the RYGB cohort was more likely to develop mild anemia (hazard ratio [HR] = 1.36, P<.001), moderate anemia (HR = 1.75, P<.001), and severe anemia (HR = 1.87, P<.001). Severity of anemia was associated with an increasing percentage of microcytosis (P<.0001). Clinical factors independently associated with an increased risk of severe anemia within the RYGB cohort included females and males>40 years of age (HR = 2.97, 95% confidence interval [CI] = 1.14, 7.75, P = .026), preoperative anemia (HR = 1.65, 95% CI = 1.19, 2.29, P = .0029), preoperative low ferritin level (HR = 2.28, 95% CI = 1.39, 3.74, P = .0029), and a rapid 6-month weight loss trajectory (HR = 1.71, 95% CI = 1.22, 2.38, P = .0018).Conclusions
The long-term incidence of clinically significant anemia after RYGB is alarmingly high and warrants more detailed study. 相似文献18.

Background and objective
The primary objective was to evaluate the learning curve of minimally invasive radical prostatectomy (MIRP) in our institution and analyze the salient learning curve transition points regarding oncological outcomes.Methods
Clinical, pathologic, and oncological outcome data were collected from our prospectively collected MIRP database to estimate positive surgical margin (PSM) and biochemical recurrence (BCR) trends during a 15-year period from 1998 to 2013. All the radical prostatectomies (laparoscopic prostatectomy [LRP]/robot-assisted laparoscopic radical prostatectomy [RARP]) were performed by 9 surgeons. PSM was defined as presence of cancer cells at inked margins. BCR was defined as serum prostate-specific antigen >0.2 ng/ml and rising or start of secondary therapy. Surgical learning curve was assessed with the application of Kaplan-Meier curves, Cox regression model, cumulative summation, and logistic model to define the “transition point” of surgical improvement.Results
We identified 5,547 patients with localized prostate cancer treated with MIRP (3,846 LRP and 1,701 RARP). Patient characteristics of LRP and RARP were similar. The overall risk of PSM in LRP was 25%, 20%, and 17% for the first 50, 50 to 350, and>350 cases, respectively. For the same population, the 5-year BCR rate decreased from 30% to 16.7%. RARP started 3 years after the LRP program (after approximately 250 LRP). The PSM rate for RARP decreased from 21.8% to 20.4% and the corresponding 5-year BCR rate decreased from 17.6% to 7.9%. The cumulative summation analysis showed significantly lower PSM and BCR at 2 years occurred at the transition point of 350 cases for LRP and 100 cases for RARP. In multivariable analysis, predictors of BCR were prostate-specific antigen, Gleason score, extraprostatic disease, seminal vesicle invasion, and number of operations (P<0.05). Patients harboring PSM showed higher BCR risk (23% vs. 8%, P< 0.05).Conclusions
Learning curve trends in our large, single-center experience show correlation between surgical experience and oncological outcomes in MIRP. Significant reduction in PSM and BCR risk at 2 years is noted after the initial 350 cases and 100 cases of LRP and RARP, respectively. 相似文献19.

Background
Biliopancreatic diversion with duodenal switch (BPD-DS) is one of the most effective bariatric surgeries, in terms of weight loss and remission of co-morbidities. It is however associated with a significant risk of protein and nutritional deficiency, as well as gastrointestinal side effects.Objectives
To assess the effect of increasing the strict alimentary limb on weight loss, nutritional deficiency and quality of life, compared with standard BPD-DS.Settings
University-affiliated tertiary care center.Methods
Prospective randomized double blind (patient-evaluator) trial in which patients were assigned in a 1:1 ratio to undergo a modified BPD-DS with a long alimentary limb (1 m from Treitz ligament, n = 10) or a standard biliopancreatic diversion (strict alimentary limb of 1.5 m, n = 10). Common channel was kept at 100 cm in both groups. Follow-up at 12 months was completed in all patients.Results
Initial weight (126 ± 10 versus 125 ± 17, P = .92), age (40 ± 7 versus 37 ± 8, P = .35), and sex ratio (1 female/9 males) were similar in both groups. Excess weight loss and total weight loss were significantly higher in the standard BPD-DS group (93.4 ± 12% versus 73.3 ± 7%, P = .0007 and 46 ± 5.6% versus 37 ± 3.4%, P = .0004). The study group had significantly higher vitamin D, manganese, and copper levels at 12 months. Both groups had similar drop in glycated hemoglobin, cholesterol levels, and resolution of co-morbidities at 12 months. Long alimentary limb was associated with significantly less bowel movements a day (1.6 ± .97 versus 2.55 ± 1.01, P = .01), less gastrointestinal side effects (bloating and gas, P<.05) and required less pancreatic enzymes supplements (0 versus 40%, P = .04) and calcium supplement. Quality of life was significantly improved in both groups in all domains (all P<.05).Conclusion
At 12 months, weight loss was lesser in the long alimentary limb group. There was however no difference in the remission of co-morbidities and higher levels of vitamin D, manganese, and copper. Gastrointestinal adverse effects and the need for pancreatic enzymes were less with similarly excellent quality of life at 12 months. Longer follow-up is necessary to evaluate long-term weight loss and nutritional deficiencies. 相似文献20.
