Summary Background: Radiofrequency powered segmental thermal ablation Closure FAST has become a globally engaged technology for ablation of incompetent great saphenous veins (GSVs). Mid-term results of slowly resolving side effects are still not described. Methods: RSTA-treated GSVs (n = 295) were followed for 24 months in a prospective multicenter trial. Clinical control visits included flow and reflux analysis by duplex-ultrasound and assessment of treatment related side effects at all times. Results: 280 of 295 treated GSVs (94.9%) were available for 24 months follow-up. According to the method of Kaplan and Meier at 24 months after the intervention 98.6% of treated legs remained free of clinically relevant axial reflux. The average VCSS score improved from 3.9 ± 2.1 at screening to 0.7 ± 1.2 at 24 months follow-up (p < 0.0001). While only 41.1% of patients were free of pain before treatment, at 24 months 99.3% reported no pain and 96.4% did not experience pain during the 12 months before. At 24 months n=3 legs showed pigmentation along the inner thigh and one leg showed study-treatment related paresthesia. Conclusion: Radiofrequency powered segmental thermal ablation Closure FAST showed a very moderate side-effect profile in conjunction with a high and durable clinical success rate.

Objective the aim of this study was to assess the results of mechanochemical endovenous ablation either in the primary or recurrent saphenous vein insufficiency, including only patients with veno-venous shunt type III. Methods retrospective analysis of a prospective study of patients with symptomatic chronic venous insufficiency who underwent ClariVein® technique. A total of 134 saphenous veins were included between August 2017 and August 2018. Follow-up was performed by Duplex ultrasound at 1, 6 and 12 months. Primary endpoints were technical and anatomical success. Secondary endpoints were the need for further treatment of varicose collateral veins by sclerotherapy, outcomes regarding recurrent insufficiency and clinical success. Results A total of 111 great saphenous veins and 23 small saphenous veins were treated with a technical success of 95.6%. The overall anatomical success rates at 1, 6 and 12 month were 96.2%, 88.8% and 84.4%, respectively, without differences between primary and recurrent insufficiency. Deferred sclerotherapy over varicose collaterals was carried out in 28% of the patients with anatomical success. Clinical improvement was achieved in 87.3%. Conclusions MOCA technique has proven to be an effective technique, although additional treatment over varicose collaterals could be necessary in up to one-third. Atrophy of the saphenous vein and the lack of persistent varicose collateral veins during follow-up seem to be indicators of successful therapy.

The Moment

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

Aim: To compare the clinical and radiographic outcomes observed in Necrotic Immature Permanent Teeth (NIPT) after revascularization or apexification with MTA-apical plug. Methodology: PubMed/MEDLINE, Web of science and Scopus were the databases used, up to July 30th, 2017, for article research. Independent reviewers read the titles and abstracts of all reports that met inclusion/exclusion criteria: prospective or retrospective clinical studies comparing the revascularization of root canal and apexification. Clinical success of therapies, deposition and thickening of lateral dentinal walls (root width) and the continuation of root development (root length) were investigated. Bias risk of included studies was assessed using the Cochrane risk of bias. Results: From 1642 records, five papers fulfilled all inclusion criteria. Overall, 91 teeth were submitted to revascularization and 64 teeth to apexification with MTA. The mean follow-up was 23.2 months in revascularization and 21.8 in apexification. Clinical success rate was of 87.9% in the revascularization group and 90.6% in the apexification group. An increase on lateral dentinal walls thickening was observed in most revascularization cases (13%) while MTA as apical plug suggest a mild resorption of the root (1.3%). High bias risk was observed on included studies. Conclusions: Apexification with MTA-apical plug provides similar clinical success to revascularization. However, radiographic measurements showed an improvement in thickening of lateral dentinal walls in most of the revascularization cases in addition to a higher dental development. However, these results should be interpreted with caution.

Background. Endoscopic transpapillary gallbladder stenting (ETGBS) is an effective procedure for treating high-risk patients with acute cholecystitis and severe comorbidities. However, the efficacy of ETGBS for recurrent cholecystitis (RC) remains unclear. This study aimed to explore its efficacy in patients with RC for whom cholecystectomy is contraindicated because of its high surgical risk.Methods. Data on 19 high-risk patients who had undergone ETGBS for RC after initial conservative therapy in our institution between June 2006 and May 2012 were retrospectively examined. The primary outcome was the clinical success rate, which was defined as no recurrences of acute cholecystitis after ETGBS until death or the end of the follow-up period. Secondary outcomes were technical success rate and adverse events (AEs).Results. The clinical success rate of ETGBS was 100%, the technical success rate 94.7%, and AE rate 5%: one patient developed procedure-related mild acute pancreatitis. The clinical courses of all patients were as follows: four died of nonbiliary disease, and the remaining 15 were subsequently treated conservatively. The median duration of follow-up was 14.95 months (range 3–42 months).Conclusions. ETGBS is an effective alternative for managing RC in high-risk patients with severe comorbidities.

Abstract Background: Data on the long-term outcomes of gastric peroral endoscopic myotomy (G-POEM) for refractory gastroparesis are lacking. We report the results of a large multicenter long-term follow-up study of G-POEM for refractory gastroparesis. Methods: This was a retrospective multicenter study of all G-POEM operations performed in seven expert French centers for refractory gastroparesis with at least 1 year of follow-up. The primary endpoint was the 1-year clinical success rate, defined as at least a 1-point improvement in the Gastroparesis Cardinal Symptom Index (GCSI). Results: 76 patients were included (60.5 % women; age 56 years). The median symptom duration was 48 months. The median gastric retention at 4 hours (H4) before G-POEM was 45 % (interquartile range [IQR] 29 % – 67 %). The median GCSI before G-POEM was 3.6 (IQR 2.8 – 4.0). Clinical success was achieved in 65.8 % of the patients at 1 year, with a median rate of reduction in the GCSI score of 41 %. In logistic regression analysis, only a high preoperative GCSI satiety subscale score was predictive of clinical success (odds ratio [OR] 3.41, 95 % confidence interval [CI] 1.01 – 11.54; P = 0.048), while a high rate of gastric retention at H4 was significantly associated with clinical failure (OR 0.97, 95 %CI 0.95 – 1.00; P = 0.03). Conclusions: The results confirm the efficacy of G-POEM for the treatment of refractory gastroparesis, as evidenced by a 65.8 % clinical success rate at 1 year. Although G-POEM is promising, prospective sham-controlled trials are urgently needed to confirm its efficacy and identify the patient populations who will benefit most from this procedure.

Abstract Aims  Commonly, a dysfunctional defibrillator lead is abandoned and a new lead is implanted. Long-term follow-up data on abandoned leads are sparse. We aimed to investigate the incidence and reasons for extraction of abandoned defibrillator leads in a nationwide cohort and to describe extraction procedure-related complications. Methods and results  All abandoned transvenous defibrillator leads were identified in the Danish Pacemaker and ICD Register from 1991 to 2019. The event-free survival of abandoned defibrillator leads was studied, and medical records of patients with interventions on abandoned defibrillator leads were audited for procedure-related data. We identified 740 abandoned defibrillator leads. Meantime from implantation to abandonment was 7.2 ± 3.8 years with mean patient age at abandonment of 66.5 ± 13.7 years. During a mean follow-up after abandonment of 4.4 ± 3.1 years, 65 (8.8%) abandoned defibrillator leads were extracted. Most frequent reason for extraction was infection (pocket and systemic) in 41 (63%) patients. Procedural outcome after lead extraction was clinical success in 63 (97%) patients. Minor complications occurred in 3 (5%) patients, and major complications in 1 (2%) patient. No patient died from complication to the procedure during 30-day follow-up after extraction. Conclusion  More than 90% of abandoned defibrillator leads do not need to be extracted during long-term follow-up. The most common indication for extraction is infection. Abandoned defibrillator leads can be extracted with high clinical success rate and low risk of major complications at high-volume centres.

Endovenous Thermal Ablation

Introduction: Endovascular ablation of varicose vein either by radiofrequency ablationor laser delivers sufficient thermal energy to incompetent vein segments to produce irreversible occlusion, fibrosis and ultimately disappearance of the vein.Materials and Methods: Three hundred patients with varicosities due to primary or recurrent sapheno-femoral or sapheno-popliteal junction and great or small saphenous veinreflux underwent out-patient and in-patient endovenous thermal ablation between January 2015 to December 2017.The great saphenous vein was ablated from 2-2.5 cm below sapheno-femoral junction to knee and the small saphenous vein was ablated from mid-calf to the sapheno-popliteal junction.Results: Patient returning time to normal activity was 0–1 days returning to normal daily activity were immediately after 4 hours. Duplex ultrasound follow-up (median 3-months) confirmed abolition of sapheno-femoral junction/great saphenous vein and sapheno-popliteal junction/small saphenous vein reflux in all limbs. There were no instances of skin burns or deep vein thrombosis, but, 7 patients developed transient cutaneous numbness involving sural nerve and 1 developed endovenous heat induced thrombosis 3.Conclusions: This is likely to be more effective than conventional surgery, although long-term follow up is required.  Despite being expensive in comparison to open surgery, endovenous thermal ablation is superior in terms of: minimizing pain, avoiding incision, early mobilisation and discharge. Changing the treatment distance from 2 cm to 2.5 cm peripheral to the Deep veins junction may result in a diminished incidence of endovenous heat induced thrombosis 3.
