RESUMO

OBJECTIVE: To determine the incidence of AS after right lobe living donor liver transplantation with various biliary reconstructions and to identify the predictors of this complication. MATERIAL AND METHODS: A retrospective and prospective analysis included 245 RLLDLTs for the period 2011-2018 at the Burnazjan Federal Medical Biophysical Center. The results of transplantations in 207 patients aged 19-68 years (median 43 years) were assessed. There were 82 men and 125 women. Follow-up period ranged from 10 to 98 months (median 35 months). We analyzed the relationship between surgical characteristics (preoperative data of recipients and donors, graft parameters, technical features of biliary reconstruction and features of post-transplantation period) and incidence of anastomotic strictures. A total of 58 parameters were analyzed. RESULTS: AS occurred in 20 (9.7%) recipients. Median AS-free period was 5 months (range 1-44). In 17 (85%) patients, AC developed within a year after surgery. Cumulative 1-, 2- and 5-year incidence of AS was 8.3%, 8.9%, and 11%, respectively. Significant predictors of AS were impaired arterial blood supply to the graft (HR 7.8, 95% CI 2.3-26.0, p<0.001), biliary leakage ISGLS class B or C (HR 5.0, 95% CI 2.0-12.8, p<0.001), early allograft dysfunction (HR 4.2, 95% CI 1.5-11.6, p=0.006) and female recipient (HR 3.2, 95% CI 1.1-9.9, p=0.04). In our sample, variant biliary anatomy of the graft and recipient liver, as well as technical features of biliary reconstruction did not affect the risk of AS. CONCLUSION: Variant biliary anatomy of potential donor alone should not be considered as a contraindication for organ donation and right liver lobe transplantation. Precise surgical technique, high transplantation activity, as well as experience of reconstructive interventions on the bile ducts during other operations can significantly reduce the incidence of AS after RLLDLT up to 9.7%.

RESUMO

BACKGROUND: Transthoracic esophagectomy is a crucial independent risk factor for the incidence of postoperative cardiopulmonary complications in elderly or comorbid patients. To reduce postoperative cardiopulmonary complications and promote postoperative recovery. We made an attempt to adopt the single-port inflatable mediastinoscopy combined with laparoscopy for radical esophagectomy in esophageal cancer to observe the clinical application and effect. METHOD: Data of patients with esophageal carcinoma were collected in the Hebei General Hospital from May 2018 to November 2019. The operation time, surgical blood loss, the number of dissected lymph nodes, duration of drainage tube, duration of time on the ventilator, the length of stay in ICU, postoperative complications, the length of postoperative hospital stay were collected to assess the safety and feasibility of the single-port inflatable mediastinoscopy combined with laparoscopy for radical esophagectomy in esophageal cancer. RESULTS: A total of 22 patients with esophageal cancer were analyzed in our research. There were no cases of conversion to thoracotomy、perioperative death or postoperative cardiopulmonary complications. The average operation time of all enrolled patients was 4.26 ± 0.52 h、The surgical blood loss was 142 ± 36.50 ml、The amount of dissected lymph nodes were 21.6 ± 4.2、The duration of drainage tube was 5.8 ± 2.5 days、The duration of time on the ventilator was 6.5 ± 3.4 h、The length of stay in ICU was 1.2 ± 0.4 days、The postoperative hospital stay was 12.6 ± 2.5 days. Among all the enrolled patients, one patient (4.5%) developed anastomotic fistula on the third day after surgery. Anastomotic stricture was found in 5 patients (22.7%). Pleural effusion was found in 4 cases (18.2%). Recurrent laryngeal nerve injury caused hoarseness or cough after drinking water in 3 cases (13.6%).There was one patient (4.5%) of conversion to laparotomy as the patient had serious peritoneal adhesion. All of the patients were discharged successfully. CONCLUSION: Our results showed that this surgery of single-port inflatable mediastinoscopy combined with laparoscopy for radical esophagectomy in esophageal squamous cell carcinoma is safe and feasible. The feasibility and safety could be further and better investigated with a RCT to achieve more conclusive results.

RESUMO

In the general population, there is a strong inverse relationship between the number of ideal cardiovascular health (CVH) metrics and the total incidence of cardiovascular diseases and stroke. However, the prevalence of ideal CVH is extremely low and there are few studies on its association with newly found asymptomatic intracranial arterial stenosis (AICAS). Therefore, we performed this prospective study to assess the relationship between the newly found AICAS and ideal CVH metrics in the Chinese community population. Seven ideal CVH metrics of 3,475 participants in the Asymptomatic Polyvascular Abnormalities Community study (APAC) conducted in China (1,962 men and 1,513 women between the ages of 45 and 75 years) were collected. Based on the occurrence of newly found AICAS, all participants were divided into the AICAS group and non-ICAS group. Prevalence of ideal CVH metrics was compared between the two groups. Logistic regression was used to estimate the association of newly found AICAS with ideal CVH metrics. The result was the number of ideal CVH metrics was strongly associated with age, gender, education levels and family income (each P < 0.0001). Among the seven CVH metrics total cholesterol (TC) was the only one showing significant difference between the newly found AICAS group and non-ICAS group in our 2 years observation. Participants with less ideal CVH metrics (≤3) were associated with significantly higher prevalence of AICAS than those with more (>3) ideal CVH metrics (OR, 1.27; P = 0.045). Furthermore, less (≤3) ideal CVH metrics was markedly associated with higher incidence of AICAS for all participants, younger participants (<60 years) (OR, 1.34; P = 0.046) and men participants (OR, 1.53; P = 0.032) after adjustment for gender, age, education level, family income and stroke history. Thus we conclude that participants with newly found AICAS have high prevalence of total cholesterol status, and Individuals with low ideal CVH metrics (≤3) are associated with significantly higher prevalence of asymptomatic ICAS, especially in high-risk population of young and men participants. Therefore, primordial prevention of stroke should also focus on those high-risk populations.

RESUMO

OBJECTIVE: To evaluate the hospital charges associated with central venous stenosis in pediatric patients requiring long-term central venous catheters, via associated charges and hospital length of stay (LOS). STUDY DESIGN: This institutional review board-approved retrospective review identified pediatric patients with central venous catheters and either short bowel syndrome (SBS) or end-stage renal disease (ESRD) diagnosed between 2008 and 2015 using the Pediatric Health Information System. These 2 cohorts were selected because long-term central venous access is commonly required for survival. Prevalence of central venous stenosis, total number of admissions, procedures, LOS, and associated charges were recorded. Statistical analysis performed with Wilcoxon nonparametric and 2-sample t test with a significance of P < .05. RESULTS: Of 4952 patients with SBS and 4665 patients with ESRD, 169 (3.4%) patients with SBS and 191 (4.1%) patients with ESRD were diagnosed with central venous stenosis (360 patients total [3.7%]). The cumulative median admissions and LOS was higher in patients with SBS with central venous stenosis (15 admissions and 156 days) vs those without central venous stenosis (5 admissions and 110 days) (P < .001). The cumulative median number of admissions and LOS was higher in patients with ESRD with central venous stenosis (13 admissions and 72 days) vs those without central venous stenosis (7 admissions and 42 days) (P < .001). The mean cumulative charges for patients with SBS with central venous stenosis were higher than for those without central venous stenosis ($1.89 million vs $1.11 million, respectively) (P < .001). Similarly, the mean cumulative charges for patients with ESRD with central venous stenosis were higher than for those without central venous stenosis ($1.17 millions vs $702 000, respectively) (P < .001). CONCLUSIONS: Pediatric patients with central venous stenosis have significantly higher total charges, imaging charges, number of admissions, and longer LOS. Attention to mitigate the incidence of central venous stenosis in pediatric patients requiring long-term central venous access is warranted.

RESUMO

To determine whether regular cervical dilatation is effective for preventing cervical stenosis, and to identify the associated risk factors, in postmenopausal women after LEEP. This was a prospective randomized clinical trial in postmenopausal women who underwent LEEP at our hospital between August 2018 and May 2019. Patients who met the study criteria were randomly allocated to three groups: control group (without any intervention), intervention group A (underwent cervical dilatation at the 3rd, 5th, and 8th week after LEEP) and intervention group B (underwent cervical dilatation at the 4th, 8th, and 12th week after LEEP). A colposcopic follow-up examination was conducted at 6 months after LEEP to determine the incidence of cervical stenosis. A total of 404 postmenopausal women were found to be finally eligible for the study. The rate of cervical stenosis in the control group was significantly higher than that in the intervention group, and the rate in group A was significantly lower than that in group B. We found regular dilatation after LEEP in postmenopausal women can prevent cervical stenosis. Further, the 3rd, 5th, and 8th weeks after LEEP are optimal time points. Finally, LEEP frequency and resection depth are significant risk factors and can be used to screen postmenopausal women at risk for cervical stenosis after LEEP.

RESUMO

BACKGROUND: Medical therapy and/or endoscopic balloon dilation with intralesional therapies are options for the treatment of small bowel fibrostenotic Crohn's disease (CD). AIM: To perform a systematic review summarising evidence for efficacy of systemic and endoscopic intralesional medical therapy in established small bowel strictures in adult CD patients. METHODS: A systematic search of MEDLINE, EMBASE, CENTRAL and Scopus was conducted. Primary outcomes were rates of surgical resection and repeat endoscopic dilation. Pooled event rates from random effects models across studies with 95% confidence intervals were reported. RESULTS: Ten studies describing systemic medical therapy and eight studies of intralesional injection were included. One randomised controlled trial each for systemic therapy and intrastricture injection were identified. Only observational studies were found for systemic biologic therapies, which exclusively included tumour necrosis factor (TNF) antagonists, while intralesional therapies all involved corticosteroids except for one study that evaluated infliximab. Pooled event rates for surgical resection after systemic and intralesional therapy were 28.3% (95% CI: 18.2%-41.3%) and 18.5% (95% CI: 8.3%-36.2%), respectively over a median follow-up of 23 months (range 5.5-105.8), and 21.8 months (range 5-47). Risk of repeat endoscopic balloon dilation in those with intralesional therapy was 58.3% (95% CI: 36.6%-77.3%) over a median follow-up of 21.8 months (range 5-47). CONCLUSIONS: There are no favoured therapies for patients with stricturing small bowel CD. Data are lacking for ustekinumab and vedolizumab. No endoscopic intralesional medications provided a clear benefit for prevention of repeat EBD or surgery.

RESUMO

BACKGROUND: Symptomatic intracranial stenosis was perceived to convey a high risk of recurrent stroke, but two previous trials (SAMMPRIS and VISSIT) did not show superiority of intracranial stenosis stenting over intensive medical management alone. These findings were partly due to a lower than expected risk of recurrent stroke without stenting, possibly reflecting the young age of recruits (median age <60 years), and raise questions about generalisability to routine clinical practice. We therefore studied the age-specific prevalence, predictors, and prognosis of symptomatic intracranial stenosis in a population-based cohort of patients with transient ischaemic attack and minor stroke on intensive medical management. METHODS: The Oxford Vascular Study (OXVASC) is a prospective incidence cohort study of all vascular events in a population of 92 728 people residing in Oxfordshire, UK. All patients, irrespective of age, with transient ischaemic attack and minor ischaemic stroke occurring between March 1, 2011, and March 1, 2018 (follow-up to Sept 28, 2018), were ascertained with multiple methods, including assessment in a dedicated daily emergency clinic and daily review of all hospital admissions. Imaging was by MR angiography of the intracranial and cervicocranial arteries, by CT angiography if MR angiography was contraindicated, and by transcranial Doppler and carotid ultrasound if CT angiography was contraindicated. All patients received intensive medical treatment without stenting, and those with intracranial vascular imaging were analysed in our study, which assessed the age-specific prevalence of 50-99% intracranial stenosis and the associated stroke risk of 50-99% and 70-99% stenosis (adjusted for age and vascular risk factors) during follow-up to Sept 28, 2018. FINDINGS: Of 1368 eligible patients with intracranial vascular imaging, 241 (17·6%) had 385 50-99% symptomatic or asymptomatic intracranial stenosis. The prevalence of symptomatic 50-99% intracranial stenosis increased from 29 (4·9%) of 596 at younger than 70 years to 10 (19·6%) of 51 at 90 years or older (ptrend<0·0001). Of 94 patients with 50-99% symptomatic intracranial stenosis, 14 (14·9%) had recurrent strokes (12 ischaemic and two haemorrhagic) during a median follow-up of 2·8 years (IQR 1·5-4·6). Although symptomatic intracranial stenosis conveyed an increased risk of ischaemic stroke compared with no intracranial stenosis (adjusted hazard ratio 1·43, 95% CI 1·04-1·96), the risk of same-territory ischaemic stroke in patients with 70-99% symptomatic intracranial stenosis tended to be less than those reported in the non-stenting groups of the previous trials (1-year risk 5·6% [95% CI 0·0-13·0] vs 9·4% [3·1-20·7] in VISSIT; 2-year risk 5·6% [0·0-13·0] vs 14·1% [10·1-19·4] in SAMMPRIS). INTERPRETATION: The prevalence of 50-99% symptomatic intracranial stenosis increases steeply with age in predominantly Caucasian patients with transient ischaemic attack and minor ischaemic stroke. However, the risk of recurrent stroke on intensive medical treatment of symptomatic intracranial stenosis is consistent with the two previous randomised controlled trials in younger cohorts, supporting the generalisability of the trial results to routine practice.

RESUMO

The ring finger protein 213 gene (RNF213) rs112735431 was significantly associated with intracranial artery stenosis/occlusion disease (ICASO) in Japan and Korea and to a lesser degree in China. We conducted a case-control study to examine the prevalence and correlates of the RNF213 rare variants in Chinese patients with symptomatic ICASO. A total of 503 cases including 390 ischemic stroke patients (ICASO-IS), 113 intracranial hemorrhage patients (ICASO-ICH) and 227 control subjects were recruited. The snapshot technique was used for RNF213 rare variants analysis, including rs112735431, rs148731719, rs37144111 and rs138130613. Moreover, a meta-analysis was performed to explore the relationship between RNF213 variants and ICASO in Asian. In our case-control study, we found that the rs138130613 variant was significantly associated with ICASO-IS (OR = 9.92, 95% CI 1.24-79.19, p = 0.03). The mean age of first ischemic stroke onset of variant carriers was earlier than the noncarriers (51.3 ± 18.0 versus 66.0 ± 12.9 years old, p = 0.02), but the conventional atherosclerotic risk factors and the characteristics of artery stenosis did not differ between them. In addition, the meta-analysis showed significant association between the rs112735431 polymorphism and the ICASO or ICASO-IS, and this variant was found more often in women and young-onset patients in Asia. This study suggests that the RNF213 rs112735431 and rs138130613 are genetic risk variants for ischemic stroke with intracranial artery stenosis/occlusion in China and rs112735431 is also associated with the high risk of ICASO in Asia. Further large-scale investigation of the RNF213 gene will provide new insights into pathogenetic mechanisms of symptomatic ICASO.

RESUMO

BACKGROUND/AIM: Severe benign cicatricial stricture (SBCS) is a major complication after definitive chemoradiation therapy (dCRT) for esophageal squamous cell carcinoma (ESCC). This study was conducted to investigate risk factors of SBCS in patients with localized ESCC. PATIENTS AND METHODS: This study included 197 patients with clinical stage (cSt) II/III ESCC with T3 primary tumor, treated with dCRT between 2000 and 2011. SBCS was defined as the inability to pass a 9-mm diameter endoscope or the presence of symptoms requiring treatment. RESULTS: Complete response was obtained in 87 patients (44%). Multivariate analysis revealed that hypoalbuminemia (hazard ratio=5.65; 95% confidence interval=1.50-21.28; p=0.010) and the inability to pass an endoscope (hazard ratio=5.90; 95% confidence interval=1.52-22.85; p=0.010) were risk factors of SBCS. CONCLUSION: The inability to pass an endoscope and hypoalbuminemia were identified as risk factors of SBCS in patients with cSt II/III ESCC with T3 primary tumor.

RESUMO

This retrospective study describes the incidence and prevalence of ureteral stenosis/obstruction (US/O) in a cohort of 334 renal transplants recipients in our center over the last 5 years and evaluates the risk factors that may influence the occurrence of US/O. The parameters studied included the following: history of prostate disease, smoking, urinary tract infection, renal lithiasis, ureterovesical reflux, presence and level of polar artery, type of ureterovesical anastomosis, delayed graft function, double J catheter, lymphocele, urinoma, acute rejection, prolonged catheterization, post-transplant infravesical obstruction and BK virus infection, age of the donor and recipient, and months on dialysis. Also evaluated were the nadir creatinine and instances of cold ischemia, asystole, reanastomosis, and double J catheter removal. The average incidence of US/O was 7.6% and was significantly correlated with factors of alteration of the uretero-bladder dynamics without finding a relation to vascular factors.

RESUMO

BACKGROUND: Inflammation plays an important role in atherosclerosis but the contribution of neutrophils to this process is unclear. We sought to assess whether neutrophil count is associated with intracranial atherosclerotic stenosis (ICAS). METHODS: A total of 2847 individuals were included in our study, including 1363 with acute ischemic stroke and 1484 normal controls without stroke. The presence of ICAS was confirmed by magnetic resonance angiography. The association between neutrophil count and ICAS was evaluated by multivariable logistic regression analysis. RESULTS: Among 2847 individuals included in this study, individuals with ICAS had higher neutrophil counts than those without ICAS in groups with and without stroke (P <  0.0001 for stroke group, P = 0.0097 for group without stroke). The multivariable logistic regression analysis showed that the third and fourth quartiles were independent predictors of ICAS in all the subjects (Q3: OR 1.81, 95% CI 1.39-2.37, Q4: OR 2.29, 95% CI 1.70-3.10) and patients in the fourth quartile had a higher risk for the occurrence of ICAS in stroke group (Q4: OR 2.82, 95% CI 1.79-4.48). However, there was no significant association between neutrophil count and ICAS in the group without stroke. CONCLUSIONS: The levels of circulating neutrophils were associated with the presence of ICAS. Our findings suggest that neutrophils may play a role in the pathogenesis of stroke related to ICAS and emphasize the need to develop proper strategies to control neutrophil response for the treatment of ICAS.

RESUMO

BACKGROUND: Subglottic stenosis (SGS) is a complication that develops after intubation and is characterized by respiratory distress. The aim was to evaluate patients with post-intubation SGS and to discover the factors contributing to its development. METHODS: A total of 112 patients who had a history of intubation were included. The case group consisted of 50 patients with post-extubation persistent respiratory symptoms for which flexible bronchoscopy (FOB) was conducted and showed SGS. The control group consisted of 62 patient with no post-extubation persistent respiratory symptoms, for whom FOB was not done (n = 54), and who had post-extubation persistent respiratory symptoms and underwent FOB, which did not show subglottic stenosis (n = 8). RESULTS: No significant differences were detected related to age, gender, and gestational age. The median number of recurrent intubations was 2.5 and 3 in the case group and in control group, respectively (P = 0.14). The median duration of intubation was 20.5 days in the case group, and 6 days in the control group (P < 0.001). The Myer-Cotton classification indicated a degree of obstruction of grade 1 (mild) in 30% (n = 15), grade 2 in 16% (n = 8), grade 3 in 48% (n = 24), and grade 4 in 6% (n = 3) of the case group. CONCLUSION: The duration of intubation was found to be a significant risk factor for SGS development. Age at intubation, gender, gestational age, indication of intubation, and the number of recurrent intubations were found to have no significant association. Patients with post-extubation persistent respiratory problems, especially those with prolonged intubations, should be evaluated for SGS.

OBJECTIVE: To evaluate differences in the incidence of benign ureteroenteric stricture, we compared stricture rates of robot-assisted radical cystectomy (RARC) and open radical cystectomy (ORC) using Surveillance, Epidemiology, and End Results-Medicare data. METHODS: We identified 332 RARC and 1449 ORC performed between 2009 and 2014 to determine stricture rates at 6, 12, and 24 months following surgery. We defined ureteroenteric stricture as the need for procedural intervention. Additionally, we compared the incidence of stricture diagnosis. Multivariable proportional hazards regression was performed to determine factors associated with stricture development. RESULTS: The incidence of ureteroenteric stricture at 6 and 12 months was higher for RARC vs ORC at 12.1% vs 7.0% (P < .01) and 15.0% vs 9.5% (P = .01), respectively. RARC vs ORC stricture incidence at 2 years did not differ significantly at 14.6% vs 11.4% (P = .29). Similarly, the stricture diagnosis rates were significantly lower following ORC at 6, 12, and 24 months (P < .05). In adjusted analysis, RARC (HR 1.64, 95%CI 1.23-2.19) and preoperative hydronephrosis (HR 1.51, 95% CI 1.17-1.94) were associated with the development of stricture. Higher hospital volume was associated with a lower risk of stricture (HR 0.40, 95%CI 0.26-0.63). CONCLUSION: RARC is associated with a higher rate of ureteroenteric stricture diagnosis and intervention on a population-based level that is mitigated by higher hospital volume. A significant study limitation is inability to differentiate extracorporeal vs intracorporeal diversion. However, a stricture complication compounds the financial burden of care and efforts must be pursued to improve this surgical outcome.

RESUMO

BACKGROUND: The use of a small circular stapler (CS) has been reported to increase the incidence of benign anastomotic stricture of the intrathoracic anastomosis after esophagectomy, but no study has evaluated the effects of the CS size on cervical esophagogastrostomy. Based on a propensity-matched comparison, the present study was designed to determine whether the perioperative outcomes differ between 21- and 25-mm CSs after minimally invasive esophagectomy with cervical anastomosis. METHODS: From January 2015 to December 2017, 162 patients who received CS cervical esophagogastric anastomosis after minimally invasive esophagectomy for esophageal cancer were identified from our surgical database. A propensity-matched analysis was used to compare the outcomes between the 21- and 25-mm CS groups. Endpoints included anastomotic leak, dysphagia, reflux, stricture, and other major postoperative outcomes within 6 postoperative months. RESULTS: There were 69 and 93 patients in the 21- and 25-mm CS groups, respectively. Propensity matching produced 57 patients in each group. The two groups were not remarkably different in benign anastomotic stricture rate (P = 0.528). All strictures were resolved by balloon dilatation. The 25-mm CS group had a significantly longer operative time in cervical anastomosis than the 21-mm group (P = 0.005). No statistically significant differences in anastomotic leak rates, dysphagia scores, reflux scores, or other postoperative complications were noted between the two groups. CONCLUSIONS: The use of a 21-mm CS in minimally invasive esophagectomy with cervical esophagogastric anastomosis did not result in greater anastomotic stricture as compared with a 25-mm CS. The 21-mm CS was associated with a significantly shorter operative time.

RESUMO

BACKGROUND: Several technical modifications in portal vein (PV) reconstruction have shown excellent outcomes in pediatric liver transplantation (LT); however, which procedure is the best for PV reconstruction of the hypoplastic PV in pediatric LT remains unclear. METHODS: One hundred sixteen pediatric patients aged 1 or younger with biliary atresia (BA) undergoing living donor LT (LDLT) at our center were enrolled in the present study to investigate the outcomes of the different types of PV reconstruction. We compared the results between patients with and without vein graft (VG) interposition (VG group, n = 33; non-VG group, n = 83) to analyze the risk factors for PV complications (PVCs). The median follow-up period was 4.7 years. RESULTS: PVCs occurred in 10 cases (7.2%), including 5 cases in the non-VG group and 5 in the VG group. Stenosis and thrombosis occurred in 10 and 3 cases, respectively, and 3 cases suffered from both. Three patients were surgically treated for PVCs, and 2 underwent stent insertion to treat short-term recurrence after the initial treatment. The incidence of PVCs in the 2 groups did not differ to a statistically significant extent. Although retrograde PV flow was 1 of the significant risk factors in a univariate analysis, a multivariate analysis revealed that early transplant era was the only independent risk factor for PVCs. CONCLUSIONS: VG interposition for PV reconstruction in LDLT appears to be a feasible alternative option with acceptable outcomes for patients with BA. Achieving sufficient PV flow is essential to preventing PVCs after LDLT.

RESUMO

RATIONALE & OBJECTIVE: Reducing turbulent blood flow through dialysis arteriovenous fistulas (AVFs) and radial stretching of their venous wall may attenuate hyperplasia and stenosis and improve AVF outcomes in hemodialysis patients. The goal of this study was to evaluate the safety and efficacy of the VasQ implant, which intervenes on these mechanisms by physically supporting the surgical arteriovenous anastomosis. STUDY DESIGN: Prospective, randomized, controlled, multicenter study. SETTINGS & PARTICIPANTS: 40 consecutive patients with kidney failure referred for creation of a brachiocephalic fistula in 4 vascular access centers in the United Kingdom and Israel. INTERVENTIONS: AVF surgical creation with placement of the VasQ implant (treatment) versus AVF placement without the implant (control). OUTCOMES: Safety assessed as percentage of severe device-related adverse events was the primary outcome. Secondary outcomes were efficacy assessments including: (1) AVF maturation at 3 months, defined as cephalic vein diameter≥5mm and flow≥500mL/min; (2) functional cumulative patency, defined as successful 2-needle cannulation for two-thirds or more of all dialysis runs for 1 month in study participants receiving dialysis; (3) cephalic vein diameter and blood flow; and (4) primary and cumulative patency at 6 months. RESULTS: No severe device-related adverse events were observed. There was no significant difference in maturation at 3 months or primary patency at 6 months between treatment and control (85% vs 80% and 80% vs 66%). Significantly larger vein luminal diameters were observed in the treatment group versus controls at 3 and 6 months (8.27±2.2 vs 6.69±1.8mm [P=0.03] and 9.6±2.5 vs 7.56±2.7mm [P=0.03]). Functional patency at 6 months was significantly greater in the treatment group (100% vs 56% [P = 0.01]). LIMITATIONS: Small sample size, limited power for secondary end points. CONCLUSIONS: No safety signals were detected for the VasQ external support of brachiocephalic AVFs. Higher functional patency and vein luminal diameters were achieved with the device at 3 and 6 months. VasQ may safely intervene on mechanisms associated with the disturbed hemodynamic profile in the juxta-anastomotic region. FUNDING: Funded by Laminate Medical Technologies Ltd.

RESUMO

Pectus excavatum, thoracic spine deformities, tracheal hypoplasia and lateral heart displacement are frequently described in brachycephalic dog breeds. Pectus carinatum is described sporadically, although the authors' observations demonstrate that it may occur in certain brachycephalic dog breeds. It was hypothesised that dogs of screw-tailed brachycephalic breeds carry a greater risk of these anomalies than normal-tailed brachycephalic breeds, and that there could a relation between the presence of pectus excavatum or pectus carinatum and thoracic spine deformities, tracheal hypoplasia and lateral heart displacement. During retrospective studies, these anomalies were identified in lateral and dorso-ventral radiographs of the thorax in brachycephalic dog breeds. A statistical analysis revealed that the frequency of pectus excavatum occurrence in screw-tailed and normal-tailed brachycephalic dog breeds is similar. The greatest risk of pectus excavatum occurrence is carried by two breeds: Maltese (60%) and English Bulldog (58%), while for pectus carinatum: Pug (41%) and French Bulldog (18%). Dogs of screw-tailed brachycephalic breeds carry a greater risk of kyphosis (p < 0.0001), tracheal hypoplasia occurrence (p < 0.0001), compared to "normal-tailed" breeds. The hypothesis concerning a relation between the presence of pectus excavatum or pectus carinatum and the other anomalies studied was not confirmed (p > 0.05). It was demonstrated that in dogs of brachycephalic breeds there was a greater risk of co-incidence between kyphosis of the thoracic spine and lateral heart displacement (p = 0.038), as well as kyphosis of the thoracic spine and tracheal hypoplasia (p = 0.003).

RESUMO

Background: The population-based incidence of anastomotic stricture after minimally invasive oesophagectomy (MIO) and open oesophagectomy (OO) is not known. The aim of this study was to compare rates of anastomotic stricture requiring dilatation after the two approaches in an unselected cohort using nationwide data from Finland and Sweden. Methods: All patients who had MIO or OO for oesophageal cancer between 2007 and 2014 were identified from nationwide registries in Finland and Sweden. Outcomes were the overall rate of anastomotic stricture and need for single or repeated (3 or more) dilatations for stricture within the first year after surgery. Multivariable Cox regression provided hazard ratios (HRs) with 95 per cent confidence intervals, adjusted for age, sex, co-morbidity, histology, stage, year, country, hospital volume, length of hospital stay and readmissions. Results: Some 239 patients underwent MIO and 1430 had an open procedure. The incidence of strictures requiring one dilatation was 16·7 per cent, and that for strictures requiring three or more dilatations was 6·6 per cent. The HR for strictures requiring one dilatation was not increased after MIO compared with that after OO (HR 1·19, 95 per cent c.i. 0·66 to 2·12), but was threefold higher for repeated dilatations (HR 3·25, 1·43 to 7·36). Of 18 strictures following MIO, 14 (78 per cent) occurred during the first 2 years after initiating this approach. Conclusion: The need for endoscopic anastomotic dilatation after oesophagectomy was common, and the need for repeated dilatation was higher after MIO than following OO. The increased risk after MIO may reflect a learning curve.

RESUMO

BACKGROUND: To evaluate the outcome and complication rate in a single institution experience using the two most commonly used techniques of ureteroenteric anastomosis, the Bricker and Wallace anastomosis. METHODS: A total of 137 patients underwent ileal conduit for bladder cancer. Ureters were anastomosed by two experienced surgeons, one performing a Bricker and the other, a Wallace anastomosis. Stricture was identified during clinical follow-up. RESULTS: Seventy-five patients underwent a Bricker anastomotic, and 65 received a Wallace anastomosis. The average age was 70 in both groups, males were predominant (66% Bricker, 70% Wallace). Follow up period was 36.5 months in Bricker group and 17 months in Wallace group. In both groups, the body mass index (BMI) was similar (26.1 kg/m2 Bricker and 26.4 kg/m2 Wallace). We observed that the stricture rate after performing the Bricker anastomosis technique was 25.3% (19/75) as compared to 7.7% (5/65) after Wallace anastomosis technique, which was statistically significant (p = 0.001). In the Bricker group, patients with strictures had higher BMI (28.3 vs. 25.7 kg/m2, p = 0.05). On average it took 8.5 months in the Bricker group and three months in the Wallace group (p = 0.6) to develop stricture. CONCLUSIONS: The stricture rate was significantly higher when Bricker technique was applied. Although the BMI was not different in both groups, patients with a higher BMI were more likely to develop stricture. We believe that the approach of the separate and refluxing technique of Bricker anastomosis especially in obese patients poses a higher risk for anastomotic stricture formation.
