Background
Anemia is a major complication for patients on chronic dialysis. Erythropoietin is effective if iron is available, however unnecessary iron supplementation results in iron overload. Reticulocyte hemoglobin equivalent (Ret-He) may be useful for assessing iron status.Methods
A national retrospective cohort study including all children on chronic dialysis in New Zealand between 2007 and 2013, pairing Ret-He with demographic information, anemia indices, and markers of iron status.Results
In 606 observations, we found a modest relationship between Ret-He and transferrin saturation (TSAT) (r?=?0.34, p?<?0.001) and a poor correlation between Ret-He and ferritin (r?=?0.09, p?=?0.04). There was a negative correlation between ferritin and hemoglobin (r?=??0.14, p?=?0.002), a weak positive correlation between TSAT and hemoglobin (r?=?0.12, p?=?0.007), and a modest positive correlation between Ret-He and hemoglobin (r?=?0.22, p?<?0.001). The diagnostic performance of Ret-He to detect absolute iron deficiency (cut-off value 28.9 pg, sensitivity 90 %, specificity 75 %, AUC 0.87) was good.Conclusions
Ret-He is a more relevant marker of iron status than ferritin and TSAT. This supports prospectively testing Ret-He to distinguish between iron deficiency and suboptimal erythropoietin dosing as competing causes for anemia. Ferritin is an unhelpful biomarker of iron deficiency in this setting.2.

Background
We compared renal functional outcomes of robotic (RPN) and open partial nephrectomy (OPN) in patients with chronic kidney disease (CKD), a definite indication for nephron-sparing surgery.Methods
A multicenter retrospective analysis of OPN and RPN in patients with baseline ≥?CKD Stage III [estimated glomerular filtration rate (eGFR) <?60 mL/min/1.73 m2] was performed. Primary outcome was change in eGFR (ΔeGFR, mL/min/1.73 m2) between preoperative and last follow-up with respect to RENAL nephrometry score group [simple (4–6), intermediate (7–9), complex (10–12)]. Secondary outcomes included eGFR decline >?50%.Results
728 patients (426 OPN, 302 RPN, mean follow-up 33.3 months) were analyzed. Similar RENAL score distribution (p?=?0.148) was noted between groups. RPN had lower median estimated blood loss (p?<?0.001), and hospital stay (3 vs. 5 days, p?<?0.001). Median ischemia time (OPN 23.7 vs. RPN 21.5 min, p?=?0.089), positive margin (p?=?0.256), transfusion (p?=?0.166), and 30-day complications (p?=?0.208) were similar. For OPN vs. RPN, mean ΔeGFR demonstrated no significant difference for simple (0.5 vs. 0.3, p?=?0.328), intermediate (2.1 vs. 2.1, p?=?0.384), and complex (4.9 vs. 6.1, p?=?0.108). Cox regression analysis demonstrated that decreasing preoperative eGFR (OR 1.10, p?=?0.001) and complex RENAL score (OR 5.61, p?=?0.03) were independent predictors for eGFR decline >?50%. Kaplan–Meier analysis demonstrated 5-year freedom from eGFR decline >?50% of 88.6% for OPN and 88.3% for RPN (p?=?0.724).Conclusions
RPN and OPN demonstrated similar renal functional outcomes when stratified by tumor complexity group. Increasing tumor age and tumor complexity were primary drivers associated with functional decline. RPN provides similar renal functional outcomes to OPN in appropriately selected patients.3.

Introduction
Diuretic therapy has been the mainstay of treatment in chronic kidney disease (CKD) patients, primarily for hypertension and fluid overload. Apart from their beneficial effects, diuretic use is associated with adverse renal outcomes. The current study is aimed to determine the outcomes of diuretic therapy.Methodology
A prospective observational study was conducted by inviting pre-dialysis CKD patients. Fluid overload was assessed by Bioimpedance analysis (BIA).Results
A total 312 patients (mean age 64.5?±?6.43) were enrolled. Among 144 (46.1%) diuretic users, furosemide and hydrochlorothiazide (HCTZ) were prescribed in 69 (48%) and 39 (27%) patients, respectively, while 36 (25%) were prescribed with combination therapy (furosemide plus HCTZ). Changes in BP, fluid compartments, eGFR decline and progression to RRT were assessed over a follow-up period of 1 year. Maximum BP control was observed with combination therapy (?19.3 mmHg, p?<?0.001) followed by furosemide [?10.6 mmHg with 80 mg thrice daily (p?<?0.001)], ?9.3 mmHg with 40–60 mg (p?<?0.001) and ?5.9 mmHg with 20–40 mg (p?=?0.02) while HCTZ offered minimal SBP control [?3.7 mmHg with 12.5–25 mg (p?=?0.04)]. Decline in extracellular water (ECW) ranged from ?1.5 L(p?=?0.01) with thiazide diuretics to ?3.8 L(p?<?0.001) with combination diuretics. Decline in eGFR was maximum (?3.4 ml/min/1.73 m2, p?=?0.01) with combination diuretics and least with thiazide diuretics (?1.6 ml/min/1.73 m2, p?=?0.04). Progression to RRT was observed in 36 patients.Conclusion
It is cautiously suggested to discourage the use of diuretic combination therapy and high doses of single diuretic therapy. Prescribing of diuretics should be done by keeping in view benefit versus harm for each patient.4.
Background
Obesity is often associated with fatty liver (FL). In most cases, bright liver at ultrasound (US) and increased alanine aminotransferase (ALT) and gamma-glutamyltranspeptidase (GGT) levels are considered the hallmarks of nonalcoholic fatty liver disease (NAFLD). Insulin resistance (IR) is the main link between obesity and NAFLD. The use of the Bioenterics® intragastric balloon (BIB) is a safe procedure either for inducing a sustained weight loss with diet support or for preparing those patients who are candidates for bariatric surgery. The aim of the study was to investigate whether the weight loss induced by intragastric balloon might improve IR and liver enzymes. The presence or absence of FL at US and the influence of a body mass index (BMI) decrease ≥10% after BIB (ΔBMI?≥?10%) were also considered.Methods
One hundred and three consecutive obese (BMI?>?30 kg/m2) patients (38 males/65 females; mean age 41.3, range 20–63 years) underwent BIB insertion under endoscopic control. The BIB was removed 6 months later. US, clinical, and routine laboratory investigations were performed before and after BIB. IR was calculated by the homeostasis model assessment (HOMA-IR?>?2.5). Exclusion criteria were hepatitis B virus positive, hepatitis C virus positive, alcohol consumption >30 g/day, history of hepato-steatogenic drugs, and type 1 diabetes.Results
Ninety-three patients were eligible for the study. The BMI significantly decreased in all investigated patients, and it was ≥10% in 59% of the patients. FL was seen at US in 70%, impaired fasting blood glucose was present in 13%, ALT exceeded the normal limit in 30.1%, GGT exceeded the normal limit in 15%, and HOMA-IR was >2.5 in 85%. Median HOMA-IR decreased significantly in FL (4.71 vs 3.10; p?0.05) and non-FL (3.72 vs 2.81; p?0.01) groups. Median ALT decreased significantly in the FL group (31.5 vs 24; p?0.001) and GGT significantly decreased in the FL group (31 vs 23.5; p?0.05). In the FL group with ΔBMI?≥?10%, the median values of HOMA-IR (4.95 vs 2.69; p?0.05), ALT (30 vs 23; p?0.01), and GGT (28 vs 20; p?0.001) significantly decreased after BIB. In the non-FL group, HOMA-IR values significantly decreased (4.07 vs 2.36; p?0.01) in patients with a ΔBMI?≥?10%; ALT and GGT did not significantly decrease.Conclusions
Weight loss induced by intragrastric balloon reduces IR. The ALT and GGT decrease suggests an improvement in hepatic damage. The benefit depends on the decrease of BMI higher than 10%.5.

Background
The objective of this study was to assess predictors for new-onset stone formers after Roux-en-Y gastric bypass (RYGBP).Methods
One hundred and fifty-one obese patients underwent RYGBP and were followed for 1 year. The analysis comprised two study time points: preoperative (T0) and 1 year after surgery (T1). They were analyzed for urinary stones, blood tests, and 24-h urinary evaluation. Nonparametric tests, logistic regression, and multivariate analysis were conducted using SPSS 17.Results
Median BMI decreased from 44.1 to 27.0 kg/m2 (p?<?0.001) in the postoperative period. Urinary oxalate (24 versus 41 mg; p?<?0.001) and urinary uric acid (545 versus 645 mg; p?<?0.001) increased significantly postoperatively (preoperative versus postoperative, respectively). Urinary volume (1310 versus 930 ml; p?<?0.001), pH (6.3 versus 6.2; p?=?0.019), citrate (268 versus 170 mg; p?<?0.001), calcium (195 versus 105 mg; p?<?0.001), and magnesium (130 versus 95 mg; p?=?0.004) decreased significantly postoperatively (preoperative versus postoperative, respectively). Stone formers increased from 16 (10.6 %) to 27 (17.8 %) patients in the postoperative analysis (p?=?0.001). Predictors for new stone formers after RYGBP were postoperative urinary oxalate (p?=?0.015) and uric acid (p?=?0.044).Conclusions
RYGBP determined profound changes in urinary composition which predisposed to a lithogenic profile. The prevalence of urinary lithiasis increased almost 70 % in the postoperative period. Postoperative urinary oxalate and uric acid were the only predictors for new stone formers. 相似文献6.

Background
Dialysis-related destructive spondyloarthropathy caused by beta-2 microglobulin (β2M) amyloid deposits in intervertebral discs is a major burden for patients undergoing long-term dialysis. This study aimed to quantify the presence of β2M amyloid deposits in the intervertebral disc tissue of such patients and analyze whether there was a significant correlation between β2M accumulation and the duration of dialysis.Methods
Two groups of patients who had undergone surgery for degenerative spinal pathologies were selected: the dialysis group (n?=?29) with long-term dialysis and the control group (n?=?10) with no renal impairment. Tissue sections were prepared from specimens of intervertebral disc tissue obtained during spinal surgery and analyzed via histological staining, including immunohistochemistry (IHC) and Congo red.Results
There was a statistically significant multifold increase of β2M expression in the disc tissue of long-term dialysis patients when compared to non-dialysis patients, as shown by both IHC (0.019?±?0.023 μm2 vs. 0.00020?±?0.00033 μm2, respectively; p?=?0.012) and Congo red staining (0.027?±?0.041 μm2 vs. 9.240?×?10?5?±?5.261?×?10?5 μm2, respectively; p?=?0.047). We also note a moderate strength positive correlation between the duration of dialysis and positive IHC (r?=?0.39; p?=?0.015) and Congo-red staining (r?=?0.42; p?=?0.007).Conclusions
The problem of β2M amyloidosis in long-term dialysis patients remains unresolved even with predominant use of high-flux dialysis membranes. This highlights the insufficiency of current dialysis modalities to effectively filter β2M.7.

Background
Although measures to reduce and treat the postoperative surgical drain output are discussed, along with the increased interest in causative factors related to the prevention and treatment reported by many studies, these are still controversial.Methods
A retrospective study was conducted on a consecutive series of 217 patients who had underwent ACCF between January 2016 and March 2017. Patients were categorized based on normal or increased total drain output. These two groups were compared for demographic distribution and clinical data to investigate the predictive factors of increased drain output by multivariate analysis.Results
The overall incidence rate of increased drain output after ACCF was 16.6%. There are no significant differences in sex, BMI, history of taking aspirin, and ASA classification between the two groups (P?>?0.05). Of the patients with increased drain output, a significantly higher proportion of patients have OPLL in the surgical level, 18 (50.0%) versus 33 (18.2%) (P?=?0.000). The mean age was 60.67?±?8.18 years versus 54.41?±?10.05 years (P?=?0.001). Number of discs involved was 2.42?±?0.50 versus 2.02?±?0.65 (P?=?0.001). Operation time was 112.22?±?16.49 min versus 105.21?±?17.89 min (P?=?0.031). Intraoperative blood loss was 109.86?±?62.02 mL versus 87.83?±?56.40 mL (P?=?0.036). Logistic regression analysis showed that age (OR, 1.075; p?=?0.003), history of smoking (OR, 2.792; p?=?0.021), OPLL in surgical level (OR, 2.107; p?=?0.001), and number of discs involved (OR, 2.764; p?=?0.003) maintained its significance in predicting likelihood of increased surgical drain output.Conclusions
The occurrence of increased drain output after ACCF is most likely multifactorial and is related to age, history of smoking, OPLL in surgical level, and number of discs involved.8.

Background
Morbidity after gastrectomy remains high. The potentially modifiable risk factors have not been well described. This study considers a series of potentially modifiable patient-specific and perioperative characteristics that could be considered to reduce morbidity and mortality after gastrectomy.Methods
This retrospective cohort study includes adults in the ACS NSQIP PUF dataset who underwent gastrectomy between 2011 and 2013. Sequential multivariable models were used to estimate effects of clinical covariates on study outcomes including morbidity, mortality, readmission, and reoperation.Results
Three thousand six hundred and seventy-eight patients underwent gastrectomy. A majority of patients had distal gastrectomy (N?=?2,799, 76.1 %) and had resection for malignancy (N?=?2,316, 63.0 %). Seven hundred and ninety-eight patients (21.7 %) experienced a major complication. Reoperation was required in 290 patients (7.9 %). Thirty-day mortality was 5.2 %. Age (OR?=?1.01, 95 % CI?=?1.01–1.02, p?=?0.001), preoperative malnutrition (OR?=?1.65, 95 % CI?=?1.35–2.02, p?<?0.001), total gastrectomy (OR?=?1.63, 95 % CI?=?1.31–2.03, p?<?0.001), benign indication for resection (OR?=?1.60, 95 % CI?=?1.29–1.97, p?<?0.001), blood transfusion (OR?=?2.57, 95 % CI?=?2.10–3.13, p?<?0.001), and intraoperative placement of a feeding tubes (OR?=?1.28, 95 % CI?=?1.00–1.62, p?=?0.047) were independently associated with increased risk of morbidity. Association between tobacco use and morbidity was statistically marginal (OR?=?1.23, 95 % CI?=?0.99–1.53, p?=?0.064). All-cause postoperative morbidity had significant associations with reoperation, readmission, and mortality (all p?<?0.001).Conclusions
Mitigation of perioperative risk factors including smoking and malnutrition as well as identified operative considerations may improve outcomes after gastrectomy. Postoperative morbidity has the strongest association with other measures of poor outcome: reoperation, readmission, and mortality.9.

Background
This study utilized a multi-institutional database to evaluate risk factors for readmission in patients undergoing curative gastrectomy for gastric adenocarcinoma with the intent of describing both perioperative risk factors and the relationship of readmission to survival.Methods
Patients who underwent curative resection of gastric adenocarcinoma from 2000 to 2012 from seven academic institutions of the US Gastric Cancer Collaborative were analyzed. In-hospital deaths and palliative surgeries were excluded, and readmission was defined as within 30 days of discharge. Univariate and multivariable logistic regression analyses were employed and survival analysis conducted.Results
Of the 855 patients, 121 patients (14.2 %) were readmitted. Univariate analysis identified advanced age (p?<?0.0128), American Society of Anesthesiology status ≥3 (p?=?0.0045), preexisting cardiac disease (p?<?0.0001), hypertension (p?=?0.0142), history of smoking (p?=?0.0254), increased preoperative blood urea nitrogen (BUN; p?=?0.0426), concomitant pancreatectomy (p?=?0.0056), increased operation time (p?=?0.0384), estimated blood loss (p?=?0.0196), 25th percentile length of stay (<7 days, p?=?0.0166), 75th percentile length of stay (>12 days, p?=?0.0256), postoperative complication (p?<?0.0001), and total gastrectomy (p?=?0.0167) as risk factors for readmission. Multivariable analysis identified cardiac disease (odds ratio (OR) 2.4, 95 % confidence interval (CI) 1.6–3.3, p?<?0.0001), postoperative complication (OR 2.3, 95 % CI 1.6–5.4, p?<?0.0001), and pancreatectomy (OR 2.2, 95 % CI 1.1–4.1, p?=?0.0202) as independent risk factors for readmission. There was an association of decreased overall median survival in readmitted patients (39 months for readmitted vs. 103 months for non-readmitted). This was due to decreased survival in readmitted stage 1 (p?=?0.0039), while there was no difference in survival for other stages. Stage I readmitted patients had a higher incidence of cardiac disease than stage I non-readmitted patients (58 vs. 24 %, respectively, p?=?0.0002).Conclusions
Within this multi-institutional study investigating readmission in patients undergoing curative resection for gastric cancer, cardiac disease, postoperative complication, and concomitant pancreatectomy were identified as significant risk factors for readmission. Readmission was associated with decreased overall median survival, but on further analysis, this was driven by differences in survival for stage I disease only.10.
Purpose
Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease; however, the frequency of recurrence can be reduced if curative surgery following adjuvant chemotherapy is applied. At present, adjuvant chemotherapy is uniformly performed in all patients, as it is unclear which tumor types are controlled best or worst. We investigated patients with recurrence to establish the optimum treatment strategy.Methods
Of 138 patients who underwent curative surgery for PDAC, 85 developed recurrence. Comprehensive clinicopathological factors were investigated for their association with the survival time after recurrence (SAR).Results
The median SAR was 12.6 months. Treatments for recurrence included best supportive care, GEM-based therapy and S-1. The performance status [hazard ratio (HR) 0.12, P?<?0.001], histological invasion of lymph vessels (HR 0.27, P?<?0.001), kind of treatment for recurrence (HR 5.0, P?<?0.001) and initial recurrence site (HR 2.9, P?<?0.001) were independent significant risk factors for the SAR. The initial recurrence sites were the liver (n?=?21, median SAR 8.8 months), lung (n?=?10, 14.9 months), peritoneum (n?=?6, 1.7 months), lymph nodes (n?=?6, 14.7 months), local site (n?=?17, 13.9 months) and multiple sites (n?=?25, 10.1 months). A shorter recurrence-free survival (<?1 year) and higher postoperative CA19-9 level were significantly associated with critical recurrence (peritoneal/liver).Conclusions
Several risk factors for SAR were detected in this study. Further investigations are needed to individualize the adjuvant chemotherapy for each patient with PDAC.11.

Introduction and hypothesis
There is no consensus on the most appropriate type of anesthesia for placement of a midurethral sling. Our objective was to compare intra- and perioperative outcomes for this procedure performed under general anesthesia versus monitored anesthesia care.Methods
Retrospective cohort analysis of women undergoing outpatient placement of synthetic retropubic midurethral sling under general anesthesia (n?=?141) or monitored anesthesia care (n?=?84). Patients undergoing concomitant procedures were excluded. Primary outcome was operating room time. Secondary outcomes included surgical and recovery times, cost, discharge home with a catheter, and postoperative pain and/or nausea.Results
In the general anesthesia group, both operating room time (mean?±?SD, 67.6?±?13.3 min vs 56.9?±?11.8 min, p?<?0.001) and recovery room time (240.0?±?69.8 min vs 190.1?±?78.3 min, p?<?0.001) were longer, whereas there was no difference in surgical time (30.0?±?8.9 min vs 29.0?±?9.7 min, p?=?0.43). Cost was significantly higher in the general anesthesia group ($4,095?±?715 vs $3,877?±?777, p?=?0.03). There was no difference in rates of bladder perforation (6.4 % vs 11.9 %, p?=?0.33). Patients who underwent general anesthesia had higher rates of discharge with a catheter (27.0 % vs 15.8 %, p?=?0.04).Conclusion
Monitored anesthesia care may offer significant benefits over general anesthesia in women undergoing retropubic midurethral sling, including shorter operating room and recovery times, lower costs, and less voiding dysfunction in the immediate postoperative period.12.

Background
HAL colectomy is a technique perceived to provide the benefits of laparoscopic surgery while improving tactile feedback and operative time. Published data are largely limited to small, single-institution studies.Methods
The 2012-2013 National Surgical Quality Improvement Program Participant Data Use File was queried for patients undergoing elective SL or HAL colectomy. Patients underwent 1:1 propensity matching and had outcomes compared. An additional subgroup analysis was performed for patients undergoing segmental resections only.Results
13,949 patients were identified, of whom 6084 (43.6 %) underwent HAL colectomy. Patients undergoing HAL versus SL colectomy had higher rates of postoperative ileus (8.7 vs. 6.3 %, p?<?0.001), wound complication (8.8 vs. 6.8 %, p?=?0.006), and 30-day readmission (7.5 vs. 6.0 %, p?=?0.002), without any differences in operative time (156 vs. 157 min, p?=?0.713). Amongst segmental colectomies, HAL remained associated with higher rates of wound complications (8.6 vs. 6.5 %, p?=?0.016), postoperative ileus (8.9 vs. 6.3 %, p?<?0.001), and 30-day readmission (7.1 vs. 5.9 %, p?=?0.041) with no difference in operative time between HAL and SL (145 vs. 145 min, p?=?0.334).Conclusions
Use of HAL colectomy is associated with increased risk of wound complications, postoperative ileus, and readmissions. Importantly, this technique is not associated with any decrease in operative time.13.

Purpose
To compare serum level of vitamin D [25(OH)D] in patients with life-long premature ejaculation (LPE) versus healthy controls.Methods
Healthy married potent males were recruited from February 2017 to January 2018. Group A included 40 patients suffering from LPE who were compared versus 40 healthy controls (Group B). Participants suffering from hormonal disorders, obesity, neurological, psychological, or chronic diseases or taking medications that may affect ejaculatory function, serum level of vitamin D, or the accuracy of intra-vaginal ejaculation latency time (IELT) were excluded. LPE was self-reported by the patients with subsequent feelings of frustration and measured by premature ejaculation diagnostic tool (PEDT) and IELT using stopwatch handled by their partners. 25(OH)D was measured by obtaining 2 ml of venous blood. Statistical analysis was performed using Student t, Mann–Whitney, Chi square tests, logistic regression analysis, and Spearman correlation.Results
Sixteen (20%) participants had vitamin D insufficiency/deficiency. All of them were in PE group. 25(OH)D correlated significantly with IELT (r2?=?0.349; p?<?0.001) and PEDT (r2?=?0.425; p?<?0.001). There was no statistically significant difference in age (p?=?0.341), BMI (p?=?1) or IIEF-5 (p?=?0.408) in both groups. 25(OH)D was significantly lower in patients than controls (35.75 vs. 58.92 ng/ml, p?<?0.001). ROC analysis revealed that the best cut-off value of 25(OH)D to detect patients suffering from LPE was 50.65 ng/ml with a sensitivity and specificity of 85% for both. 25(OH)D remained a significant risk factor for LPE in the logistic regression analysis (p?<?0.001).Conclusions
The current study showed that vitamin D has significant association with LPE and correlates significantly with IELT and PEDT.14.

Introduction
We hypothesized that an elevated preoperative alkaline phosphatase (AP) predicted worse outcomes for patients undergoing transarterial chemoembolization (TACE) for neuroendocrine tumor (NET) liver metastases.Methods
We reviewed all patients who underwent TACE for metastatic NET between 2009 and 2013. Survival was evaluated using preprocedure variables.Results
One hundred and nine patients underwent 210 TACE procedures. The average age was 57.7 years (range 20–78). Primary sites included pancreas (N?=?20), other gastrointestinal (N?=?52), lung (N?=?9), and unknown (N?=?28). The tumor was grade 1 in 68 (62 %), grade 2 in 21 (19 %), and grade 3 in 3 (3 %). Extrahepatic disease was present in 54 (50 %) and greater than 50 % hepatic tumor burden by imaging in 63 (58 %). Elevated bilirubin occurred in 8 (7 %), elevated AP in 22 (20 %), elevated ALT in 21 (19 %), and elevated AST in 41 (38 %). Univariate predictors included tumor grade (43 vs 27 vs 21 months, p?=?0.015), hepatic tumor burden (59 vs 37 months, p?=?0.009), and elevated AP (59 vs 23 months, p?<?0.001). On multivariate analysis, only elevated AP (p?=?0.001) predicted worse survival.Conclusions
Elevated AP prior to TACE for metastatic NET portends a worse survival outcome, even more so than tumor grade or extent of hepatic disease.15.

Background
Non-alcoholic fatty liver disease (NAFLD) is a common, severe disease in obese patients. However, NAFLD is usually underestimated by ultrasonography. Liver biopsy is not routinely done in bariatric surgery or during the follow-up. This study therefore examined the correlation between metabolic syndrome and NAFLD in morbidly obese patients based on an assessment using transient hepatic elastography (THE).Material and Methods
This study involved 50 female patients in the pre-operative phase for bariatric surgery. Before surgery, we collected clinical, laboratory, and anthropometric variables. THE measurements were obtained using a FibroScan® device (Echosens, Paris, France), and steatosis was quantified using Controlled Attenuation Parameter software (CAP). Statistical analyses were done using linear correlation and the Kruskal-Wallis test.Results
The mean of THE and CAP values were 7.56?±?4.78 kPa and 279.94?±?45.69 dB/m, respectively, and there was a significant linear correlation between the two measurements (r?=?0.651; p?<?0.001). The numbers of metabolic syndrome parameters did not influence the THE (p?=?0.436) or CAP (p?=?0.422) values. HbA1c and HOMA-IR showed a strong linear correlation with CAP (r?=?0.643, p?=?0.013 and r?=?0.668, p?=?0.009, respectively) and a tendency to some linear correlation with THE (r?=?0.500, p?=?0.05 and r?=?0.500, p?=?0.002, respectively).Conclusion
Morbidly obese women submitted to FibroScan® presented a high prevalence of severe steatosis and advanced fibrosis in our sample. Insulin resistance parameters were correlated with steatosis, but less with fibrosis.16.

Purpose
We aimed to ascertain the feasibility of crowdsourcing via Facebook for medical research purposes; by investigating surgical, oncological and functional outcome and quality-of-life (QOL) in patients with pigmented villonodular synovitis (PVNS) enrolled in a Facebook community (1112 members).Methods
Patients completed online open surveys on demographics, surgery and clinical outcomes (group 1); and patient-reported outcome measures (PROMs) including knee-injury osteoarthritis outcome score (KOOS), hip-disability osteoarthritis outcome score (HOOS), Toronto extremity salvage score (TESS) and SF-36 (group 2). Mean follow-up was 70 months (12–374). Consistency checks were performed with Cohen’s kappa statistic for intra-rater agreement.Results
The first survey was completed by 272 patients (group 1) and 72 patients completed the second (group 2). In group 1, recurrence-rate was 58 % (69/118) after arthroscopic, 36 % (35/97) after open and 50 % (5/10) after combined synovectomy (p?=?0.003). In group 2, recurrence-rate was 67 % (26/39) after arthroscopic and 51 % (17/33) after open synovectomy (p?=?0.19). Recurrence-risk was increased for diffuse disease (OR?=?16; 95%CI?=?3.2–85; p?<?0.001). Mean function and QOL did not differ after arthroscopic or open synovectomy: KOOS 49 vs. 58 (p?=?0.24), HOOS 62 vs. 53 (p?=?0.56), TESS 78 vs. 82 (p?=?0.86), SF-36 61 vs. 66 (p?=?0.41). Cohen’s kappa statistic for intra-rater agreement was good to outstanding (κ?=?0.68–0.95; p?<?0.001).Conclusion
Local recurrence-risk was higher for diffuse-type disease and arthroscopic synovectomy. Functional outcome and QOL were comparable for both types of surgery. Gathering data via crowdsourcing seems a promising and innovative way of evaluating rare diseases including PVNS.17.

Introduction and hypothesis
Risk factors for obstetric anal sphincter injuries (OASIS) have been well-established in singleton pregnancies. Considering the unique characteristics of twin deliveries, our aim was to identify risk factors for OASIS that are specific to twins.Methods
A retrospective study of all vaginal twin deliveries in a tertiary center between 2000 and 2014. Women who experienced OASIS (the OASIS group) were compared with those whose anal sphincter was intact (controls).Results
Overall 717 women were eligible for the study, of whom 20 (2.8 %) experienced OASIS. Women in the OASIS group were more likely to be nulliparous (95.0 % vs 53.7 %, p?<?0.001) and were characterized by a higher gestational age at delivery (36.1?±?2.5 vs 34.6?±?3.3, p?=?0.04), a higher birth weight for both twin A and twin B (2,507?±?540 g vs 2,254?±?525 g, p?=?0.03, and 25,49?±?420 g vs 2,232?±?606 g, p?=?0.004 respectively), and a higher rate of episiotomy (40.0 % vs 14.2 %, p?=?0.001), instrumental delivery for twin A (80.0 % vs 13.5 %, p?<?0.001) or twin B (80.0 % vs 18.7 %, p?<?0.001), and inter-twin delivery interval of over 30 min (20.0 % vs 7.5 %, p?=?0.04). The only factor that remained significant on multivariate analysis was instrumental delivery: forceps delivery of twin A (OR?=?8.8, 95 % CI 2.6–30.1), vacuum extraction of twin A (OR?=?9.2, 95 % CI 2.6–34.6), and forceps delivery of twin B (OR?=?15.4, 95 % CI 4.9–48.6). In women with certain combinations of risk factors the risk of OASIS was as high as 30 %.Conclusion
The overall rate of OASIS in twins is low and instrumental delivery, especially by forceps, is a risk factor.18.

Background
The population are getting older and obesity is growing. Laparoscopic sleeve gastrectomy (LSG) is increasingly used worldwide but is still used with skepticism in the elderly. The purpose of our analysis is to judge the security of LSG in patients older than 60 years compared to patients younger than 60 years.Methods
This retrospective review included data of all patients in Germany who underwent LSG between January 2005 and December 2016.The data were published online in the German Bariatric Surgery Registry. A total of 21,571 operations were gathered and divided into two groups: group I, patients <?60 years old; and group II, patients ≥?60 years old.Results
The total number of patients and the mean body mass index of group I and group II was 19,786, 51.7?±?9.5 kg/m2 and 1771, 49.2?±?8.1 kg/m2, respectively. Regarding comorbidities, group II suffered statistically significantly more comorbidities than group I (p?<?0.001). The general postoperative complications were 4.9% in group I and 7.8% in group II (p?<?0.001). There was no significant difference in special postoperative complications (p?=?0.048) and a slightly higher intraoperative complication rate in group II (2.2% vs. 1.6%, p?=?0.048). Thirty-day mortality rate for group I versus II was 0.22% and 0.23% (p?=?0.977), respectively.Conclusions
LSG is a low-risk operation and safe surgical method with acceptable, not elevated perioperative morbidity and mortality rates in patients ≥?60 years of age.19.

Background
Many benefits of minimally invasive surgery are lost in the obese, but robotic-assisted laparoscopic surgery (RALS) may offer advantages in this population. Our goal was to compare outcomes for RALS in obese and non-obese patients.Methods
A prospective database was reviewed for colorectal resections using RALS. Patients were stratified into obese (BMI?>?30 kg/m2) and non-obese cohorts (BMI?<?30 kg/m2), then case-matched for comparability. The main outcome measures were operative time, conversion rate, length of stay and complication, readmission, and reoperation rates between groups.Results
Forty-five patients were evaluated in each cohort. The BMI was significantly different (p?<?0.01). All other demographics were well matched. There were no significant differences in operative time (p?=?0.86), blood loss (p?=?0.38), intraoperative complications (p?=?0.54), or conversion rates (p?=?0.91) across cohorts. Length of stay was comparable between groups (p?=?0.45). Postoperatively, the complication (p?=?0.87), readmission (p?=?1.00), and reoperation rates (p?=?0.95) were similar. There were no mortalities. For malignant cases (37.8 %), the lymph node yield (p?=?0.48) and positive margins (p?=?1.00) were similar and acceptable in both cohorts.Conclusions
In our matched RALS series, perioperative and postoperative outcomes were similar between obese and non-obese patients undergoing colorectal surgery. RALS is a feasible option in the surgical setting of the obese patient. Further controlled studies are warranted to explore the full benefits.20.
