A first case of endoscopical removal of an eroded adjustable gastric band in Croatia.

Laparoscopic gastric banding (LAGB) is one of the most common surgical procedures in the treatment of morbid obesity since it provides good long-term outcomes in weight loss and decrease of comorbidities associated with obesity. Although the procedure has low morbidity and almost none-existing mortality, certain complications can occur. Erosion of the band into the gastric wall is one of the rare complications in LAGB. The reported incidence varies from 1 to 11%, however the largest study reported an incidence of 1.6%. This is in accordance with the incidence in our Centre for obesity, where only one case of erosion occurred among 112 operative procedures. The aim of this paper is to present a patient with gastric band erosion and it's removal by using the endoscopic techniques as a minimally invasive management method.

Treatment of atrial fibrillation with second-generation cryoballoon followed by contact-sensing radiofrequency catheter ablation for arrhythmia recurrences-results of a 5-year follow-up.

INTRODUCTION: The aim of this study was to report the long-term follow-up results of cryoballoon (CB) ablation in patients with atrial fibrillation. METHODS: All consecutive patients who underwent second-generation CB ablation from February 2015 to December 2017 were included in our study. In all procedures, we used a 28-mm CB placed via a single transseptal puncture guided by intracardiac ultrasound. A 20-mm octapolar intraluminal circular catheter was used for intracardiac recordings. A single 180-s freeze strategy was employed. Repeated procedures were performed with a 3D mapping system and radiofrequency catheters. RESULTS: A total of 126 patients (69.8% male, mean age 57 ± 11 years), of which 77.0% had paroxysmal atrial fibrillation (PAF), were included in the study. After a 5-year period, 52.4% of patients were in sinus rhythm without AF recurrence, off antiarrhythmic drugs. A total of 61.9% of patients were free of AF recurrence when redo PVI procedures were performed. When accounting for redo pulmonary vein isolation and antiarrhythmic drugs, a total of 73.8% of the patients were without AF recurrence in long-term follow-up. The patients who underwent redo pulmonary vein isolation procedures had statistically significant lower rates of AF recurrence (p = 0.006). In patients with PAF, long-term success rates improved from 62.9 to 79.4% for patients who underwent the redo procedure (p = 0.020). In patients with persistent atrial fibrillation (PersAF), success rates went up from 41.4 to 55.1% for patients with single or repeated PVI procedure (p = 0.071). In the whole cohort, a total of 3 (2.4%) procedure-related major complications occurred which included persistent PNP, arterial pseudoaneurysm, and arteriovenous fistula. CONCLUSION: Our data suggest a favorable long-term safety and efficacy profile of second-generation CB ablation. In the mixed paroxysmal and persistent population, up to 73.8% of patients remained free of AF recurrence in the 5-year follow-up, when accounting for redo procedures and AADs. Only 2.4% of patients experienced major complications of the ablation procedure, none with permanent sequelae.

Cardiac arrest in a patient with Ebstein's anomaly without accessory pathways.

We describe a case report of a patient with cardiac arrest and Ebstein's anomaly. This case report shows us necessity for arrhythmia evaluation and sudden death risk stratification even in asymptomatic patients. Prophylactic ICD implantation in this patient population is limited to observational studies and the selection of patients is impeded by the absence of randomized trials and weak predictors.

Position of intragastric balloons in global initiative for obesity treatment.

Obesity is chronic disease with multiple health consequences and among the most severe health problems worldwide. According to public health records around 65% of population in Croatia are overweight and 20% obese. National physicians chamber with support of Health and Social Welfare Ministry gave recommendations on diagnosing and treating of obesity in form of national consensus. Treatment of obesity is complex and enrolls multiple clinical specialties. Change of life style, strenuous physical activity and pharmacotherapy are part of conservative treatments. Patients are treated more efficiently by minimally invasive endoscopic procedures or bariatric surgery depending on starting body mass index score. Implantation of intragastric balloons is conceptually simple method of obesity treatment. Modern devices as Bio-Enterics intragastric balloons (BIB), (Inamed Health, USA) are gaining wide popularity among both patients and physicians. BIB intragastric offers the best gains with individuals ranging BMI from 35 to 40. Efficiency has relative timeline dependance from 85% at 6 months to 24% at 36 months. BIB offers substantial ameliorative influence on obesity comorbidities, particularly cardiovascular risk. Treatment with BIB is also efficient but transient treatment modality in morbidly and superobese individuals to reduce preoperative risks of general and bariatric surgery. Obesity treatment with BIB is well tolerated and safe, offering better quality of life. Nevertheless, due to relative poor results of conservative obesity treatments on long-term follow up further investigations defining new clinical parameters for solving treatment resistance. In order to provide resourcefully individualized approach modern perspectives are focused on endocrine constitutes of obesity. Hormonal effects of BIB treatment in compare to bariatric surgery are potentially interesting for the prospect studies.

[Clinical characteristics of patients with renovascular hypertension]. / Klinicke osobitosti bolesnika s renovaskularnom hipertenzijom.

The aim of our study was to show the value of comparing clinical parameters in patients with renovascular hypertension (RVH) and essential hypertension (EH). We examined the differences between renovascular hypertension patients with atherosclerosis (ATH) and those with fibromuscular dysplasia (FMD). The diagnosis of renovascular hypertension was established on the basis of renal angiography finding, which also defined the type of stenosis (ATH or FMD). Our patient group included 108 patients with atherosclerotic RVH (46 male / 62 female, median age 53 yrs), 16 patients with FMD (3 male / 13 female, median age 49 yrs), and 106 patients with EH (61 male / 45 female, median age 38 yrs). In comparison with patients with EH, patients with atherosclerotic RVH were found to be more frequently of female gender with lower body weight and height, older, and more frequently on therapy with antihypertensives. Their hypertension was of later onset and more severe stage. All those differences were statistically significant (P < 0.05). When analysis by genders was performed, women were more frequently smokers and had higher serum cholesterol levels, which is an explanation for higher proportion of female gender in atherosclerotic RVH patients. In patients with fibromuscular dysplasia a higher proportion of female gender was also present, but in comparison with ATH patients their hypertension was more often of a less than 5 years duration and they had lower serum creatinine and triglyceride levels. Our results are in agreement with the results of other authors who showed clinical parameters to be useful in screening of patients for further diagnostic procedure. This stresses the importance of good history, physical examination and well-chosen laboratory tests. They can't clearly establish or exclude the diagnosis of renovascular hypertension, but this approach could more easily point out those hypertensive patients who require a thorough work-up. Clinical parameters could furthermore help in determining the type of treatment of RVH.

Initial Weight Loss after Restrictive Bariatric Procedures May Predict Mid-Term Weight Maintenance: Results From a 12-Month Pilot Trial.

Background: Bariatric procedures are effective options for weight loss (WL) in the morbidly obese. However, some patients fail to lose any weight after bariatric surgery, and mid-term weight maintenance is variable. The aim of this study was to investigate whether initial WL could predict mid-term weight maintenance. Methods: Eighty patients were enrolled, of whom 44 were treated with the BioEnterics Intragastric Balloon (BIB), 21 with laparoscopic adjustable gastric lap-banding (LAGB), and 15 with laparoscopic sleeve gastrectomy (LSG). Percentage of body WL and percentage of excess weight loss (EWL) were calculated at baseline and after 1, 3, 6, and 12 months. Successful WL was defined as EWL >20% for patients treated with BIB and >50% for patients treated with LAGB and SG. Results: Success in the 6th and 12th month was achieved in 80% and 58% of patients in the BIB group, 33% and 40% in the LAGB group, and 60% and 73% in the LSG group. In the BIB group, WL in the 1st month correlated positively with WL at the 6th and 12th month, and an initial WL >6.5% best predicted success (sensitivity 50%, specificity 80%). A similar association was observed in the LAGB group at the 6th and 12th month and an initial WL >9.4% best predicted success (sensitivity 90.0%, specificity 81.2%). In patients treated with LSG, WL in the 3rd month correlated positively with EWL at the 6th and 12th month, with a cutoff value of 17% (sensitivity 66.7%, specificity 100%). Conclusions: WL in the 1st month in patients treated with BIB and LAGB and WL in the 3rd month in patients treated with LSG could be used as a prognostic factor to predict mid-term weight maintenance.

Obesity treatment using a Bioenterics intragastric balloon (BIB)--preliminary Croatian results.

AIM OF STUDY: This study aims to assess the effectiveness, tolerance, safety, and patient satisfaction of obesity treatments using the Bioenterics intragastric balloon (BIB). METHODS: Prospective controlled trial of 33 obese patients who were treated with the BIB from March 2008 to March 2009 and who completed the 6 months treatment. Patients were selected on the basis of workup by a multidisciplinary team. The 33 obese patients (26 females, seven males) had a median age of 35 years (range 20-58). Their median baseline body weight (BW) was 114 kg (range 89-197) and their median body mass index (BMI) was 41.4 kg/m(2) (range 31.2-60.8). RESULTS: Average weight reduction was 14 kg (range 2-37), loss total weight 10.1% (range 1.4-23.1), control BMI 35.6 kg/m(2) (range 29.4-50.3), delta BMI 4.5 (range 0.6-13.1), percentage excess weight loss 29.2 (range 2.8-53.6), and percent of excess BMI loss 29.3 (range 2.7-67.4). In one female patient the BIB was removed early due to intolerance. During the first week, minor side effects were noticed: nausea/vomiting occurred in 21 patients (63.6%), and abdominal cramps in 15 (45.5%). There was one balloon deflation and one impaction in the stomach. Those incidents were both successfully treated endoscopically. Patients had no major complications from mucosal lesions and no need for surgical interventions. All intragastric balloons were successfully removed endoscopically. Patients' treatment satisfaction correlated with the degree of BW loss (p = 0.0138). CONCLUSION: BIB treatment in our setting showed the best results for individuals with BMI from 35 to 40 kg/m(2). Our preliminary results showed that BIB is safe, well tolerated with minor side effects, and alters quality of life for the better. The complication rate was negligible, due to the detailed pretreatment examinations and follow-up.
