Performance of EUS-FNA for mediastinal lymphadenopathy: impact on patient management and costs in low-volume EUS centers

BACKGROUND: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of mediastinal lymphadenopathy has been shown to be a valuable diagnostic tool in high-volume EUS centers (≥ 50 mediastinal EUS-FNA/endoscopist/year). Our goal was to assess the diagnostic accuracy of EUS-FNA and its impact on clinical management and costs in low-volume EUS centers ( <50 mediastinal EUS-FNA/endoscopist/year). METHODS: Consecutive patients referred to two Dutch endoscopy centers in the period 2002-2008 for EUS-FNA of mediastinal lymphadenopathy were reviewed. The gold standard for a cytological diagnosis was histological confirmation or clinical follow-up of more than 6 months with repeat imaging. The impact of EUS-FNA on clinical management was subdivided into a positive impact by providing (1) adequate cytology that influenced the decision to perform surgery or (2) a diagnosis of a benign inflammatory disorder, and a negative impact which was subdivided into (1) false-negative or inconclusive cytology or (2) an adequate cytological diagnosis that did not influence patient management. Costs of an alternative diagnostic work-up without EUS-FNA, as established by an expert panel, were compared to costs of the actual work-up. RESULTS: In total, 213 patients (71% male, median age= 61 years, range = 23-88 years) underwent EUS-FNA. Sensitivity, specificity, and negative and positive predictive values were 89%, 100%, 80%, and 100%, respectively. EUS-FNA had a positive impact on clinical management in 84% of cases by either influencing the decision to perform surgery (49%) or excluding malignant lymphadenopathy (35%), and a negative impact in 7% of cases because of inadequate (3%) or false-negative (4%) cytology. In 9% of cases, EUS-FNA was performed without an established indication. Two nonfatal perforations occurred (0.9%). Total cost reduction was €100,593, with a mean cost reduction of €472 (SD = €607) per patient. CONCLUSIONS: Mediastinal EUS-FNA can be performed in low-volume EUS centers without compromising diagnostic accuracy. Moreover, EUS-FNA plays an important role in the management of patients with mediastinal lymphadenopathy and reduces total diagnostic cost

Urethral length in girls with lower urinary tract symptoms and forme fruste of female epispadias

To investigate systematically the length of the urethra in girls with lower urinary tract symptoms. In a group of 121 consecutive girls presented at a tertiary referral clinic for urinary incontinence or recurrent urinary tract infections, urethral length was measured by perineal ultrasound. The urethra was measured with the patient in supine position without anesthesia. Mean age of the patients was 7.8 (0-15) years. Average urethral length was 26 mm. Minimum length was 12 mm, measured in a 5-year-old girl with dribbling incontinence. Maximum measured length was 40 mm in a 15-year-old girl. In four girls (3.3%), aged 1-10 years (mean 6.3), a short urethra was detected, with measured lengths of 12 and 14 mm. All four had normal genitalia, and were referred with therapy-resistant urinary incontinence or urinary tract infections. A gradual increase in average urethral length was measured from 23 mm at birth to 32 mm at 15 years. Urethral length can be measured accurately by ultrasound. Although a short urethral length is rarely detected by ultrasound in girls with incontinence, it may be associated with therapy-resistant incontinence. In such cases, different treatment options are availabl

A fully covered self-expandable metal stent with antimigration features for benign biliary strictures : a prospective, multicenter cohort study

BACKGROUND: Self-expandable metal stents (SEMSs) are increasingly used for the treatment of benign biliary strictures (BBSs). A new fully covered SEMS (FCSEMS) with flared ends and high conformability was designed to prevent migration of the stent. OBJECTIVE: To evaluate the efficacy of a novel FCSEMS with antimigration features. DESIGN: Prospective cohort study. SETTING: Five hospitals in the Netherlands and Belgium. PATIENTS: Consecutive patients with BBS. INTERVENTION: FCSEMS placement for 3 months. MAIN OUTCOME MEASUREMENTS: Initial and long term clinical success, stent migration rate and safety. RESULTS: Thirty-eight patients (24 men; mean age, 53 ± 16 years) were included. Stent placement was technically successful in 37 patients (97%). Two patients died of an unrelated cause before stent removal, and no data on these patients were available on stricture resolution. Initial clinical success was achieved in 28 of 35 patients (80%). During follow-up after stent removal, a symptomatic recurrent stricture developed in 6 of 28 patients (21%). Overall, the long-term clinical success rate was 63% (22 of 35 patients). Stent migration occurred in 11 of 35 patients (31%), including 5 symptomatic (14%) and 6 asymptomatic (17%) migrations. In total, 11 serious adverse events occurred in 10 patients (29%), with cholangitis (n = 5) being most common. LIMITATIONS: Nonrandomized study design. CONCLUSIONS: Good initial clinical success was achieved after placement of this novel FCSEMS, but stricture recurrence was in the upper range compared with other FCSEMSs. The antimigration design could not prevent migration in a significant number of patients with a persisting stricture

Endoscopic Corticosteroid Injections Do Not Reduce Dysphagia After Endoscopic Dilation Therapy in Patients With Benign Esophagogastric Anastomotic Strictures

<p>BACKGROUND & AIMS: Benign anastomotic strictures are often difficult to treat. We assessed the efficacy of adding corticosteroid injections to endoscopic dilation therapy with Savary bougienage.</p><p>METHODS: In a multicenter, double-blind trial, 60 patients (mean age, 63 +/- 9 years; 78% male) with an untreated cervical anastomotic stricture after esophagectomy with gastric tube reconstruction and dysphagia for at least solid food were randomly assigned to groups given 4 quadrant injections of 0.5 mL triamcinolone (40 mg/mL, n = 29) or saline (controls, n = 31) into the stricture, followed by Savary dilation to 16 mm. Dysphagia, complications, and quality of life were assessed after 1 and 2 weeks and 1, 3, and 6 months. The primary end point was a dysphagia-free period of 6 months.</p><p>RESULTS: In the corticosteroid group, 45% of the patients remained dysphagia-free for 6 months, compared with 36% of controls (relative risk, 1.26; 95% confidence interval, 0.68-2.36; P = .46). Median time to repeat dilation was 108 days (range, 15-180 days) in the corticosteroid group vs 42 days (range, 17-180 days) for controls (P = .11). A median number of 2 dilations (range, 1-7) was performed in the corticosteroid group vs 3 dilations (range, 1-9) in controls (relative risk, 0.76; 95% confidence interval, 0.42-1.38; P = .36). Two major intervention-related complications occurred, 1 submucosal laceration in the corticosteroid group and 1 hemorrhage in the control group. Four patients in the corticosteroid group, but none of the controls, developed Candida esophagitis (P = .03).</p><p>CONCLUSIONS: Corticosteroid injections do not provide a statistically significant decrease in frequency of repeat dilations or prolongation of the dysphagia-free period in patients with benign anastomotic esophagogastric strictures.</p>

Dilation or biodegradable stent placement for recurrent benign esophageal strictures: a randomized controlled trial

BACKGROUND: Dilation is the standard of care for recurrent benign esophageal strictures (BES). Biodegradable stents may prolong the effect of dilation and reduce recurrences. Efficacy and safety of dilation and biodegradable stent placement early in the treatment algorithm of recurrent BES were compared. METHODS: This multicenter, randomized study enrolled patients with BES treated with previous dilations to ≥ 16 mm. The primary end point was number of repeat endoscopic dilations for recurrent stricture within 3 and 6 months. Secondary outcomes through 12 months included safety, time to first dilation for recurrent stricture, dysphagia, and level of activity. RESULTS: At 3 months, the biodegradable stent group (n = 32) underwent significantly fewer endoscopic dilations for recurrent stricture compared with the dilation group (n = 34; P < 0.001). By 6 months, the groups were similar. The number of patients experiencing adverse events was similar between the groups. Two patients in the biodegradable stent group died after developing tracheoesophageal fistulas at 95 and 96 days post-placement; no deaths were attributed to the stent. Median time to first dilation of recurrent stricture for the biodegradable stent group was significantly longer (106 vs. 41.5 days; P = 0.003). Dysphagia scores improved for both groups. Patients in the biodegradable stent group had a significantly higher level of activity through 12 months (P < 0.001). CONCLUSION: Biodegradable stent placement is associated with temporary reduction in number of repeat dilations and prolonged time to recurrent dysphagia compared with dilation. Additional studies are needed to better define the exact role of biodegradable stent placement to treat recurrent BES.status: publishe
