ObjectiveThe efficacy of argon plasma coagulation (APC) on gastric antral vascular ectasia (GAVE) may be impaired over time and depends greatly on the application settings. Endoscopic band ligation (EBL) may be an alternative, but study on its efficacy is limited. This study aimed to evaluate and compare the clinical efficacy of APC and EBL in treating GAVE.MethodsChanges in the need for blood transfusion, number of treatment sessions and hospitalizations were retrospectively assessed in 63 transfusion‐dependent patients with GAVE (mean age: 67.1 y, 54.0% female) treated with either APC or EBL (45 and 18 patients, respectively) in four tertiary endoscopic centers.ResultsBoth methods substantially increased hemoglobin levels and decreased patients' need for a transfusion (22.0 ± 4.0 g/L and −5.62 ± 2.30 units of packed red blood cells [RBC] with APC, and 27.4 ± 6.1 g/L and −4.79 ± 2.46 units of packed RBC with EBL), without a significant statistical difference between the methods. However, fewer EBL sessions were required both for the cessation of need for a transfusion compared with those for the resolution of GAVE lesions (0.90 ± 0.10 vs 1.69 ± 0.31, P = 0.028).ConclusionsBoth APC and EBL are effective in GAVE treatment. EBL may be superior in terms of number of treatment sessions, but not in its influence on hemoglobin level and need for transfusion. Further prospective studies with large, homogeneous sample size and standardized APC settings are needed.
Bevezetés: A malignus epeúti szűkületek palliatív endoszkópos kezelésekor öntáguló fém-és műanyag stentek alkalmazhatók. Az irányelvek a fémstenteket magas költségük miatt négy hónapot meghaladó várható túlélés esetén javasolják. Célkitűzés: A szerzők célul tűzték ki a malignus epeúti szűkületek esetén alkalmazott kétféle stent eredményes-ségének és költséghatékonyságának összehasonlítását. Módszer: A retrospektív vizsgálatba 37 fém-és 37 műanyag stentet kapott beteget vontak be. Meghatározták a stentek átjárhatósági idejét, szövődményrátáját és az ellátás kumulatív költségét. Eredmények: A fémstentek komplikációs rátája a műanyag stentekhez képest alacsonyabbnak (37,84 és 56,76%), míg átlagos átjárhatósági idejük hosszabbnak (19,11 és 8,29 hét; p = 0,0041) bizonyult. A stenteléssel összefüggő hospitalizációk (1,18 és 2,32; p = 0,05) és intervenciók száma szignifikánsan magasabb volt a műanyag stentes csoportban (17 és 27; p = 0,033). Esetükben a kettős stentimplantáció az átjárhatósági időt 7,68-ról 10,75 hétre emelte. Összköltség tekintetében nem találtak szignifikáns eltérést (p = 0,848). Következtetések: Költséghaté-konyság és a betegek megterhelése alapján két hónapos várható túlélés esetén fémstent-implantáció javasolható, míg rövid várható túléléskor többszörös műanyagstent-implantációra kell törekedni.

The use of metal stentsis recommended if the patient's life expectancy is more than four months. Aim: To compare the therapeutic efficacy and cost-effectiveness of metal and plastic stents in the treatment of malignant biliary obstruction. Method: The authorsretrospectively enrolledpatients who received metal (37 patients) or plastic stent (37 patients). The complication rate, stent patency and cumulative cost of treatment were assessed in the two groups. Results: The complication rate of metal stents was lower (37.84% vs. 56.76%), but the stent patency was higher compared with plastic stents (19.11 vs. 8.29 weeks; p = 0.0041). In the plastic stent group the frequency of hospitalization of patients in context with stent complications (1.18 vs. 2.32; p = 0.05) and the necessity of reintervention for stent dysfunction (17 vs. 27; p = 0.033) were substantially higher. In this group multiple stent implantation raised the stent patency from 7.68 to 10.75 weeks. There was no difference in the total cost of treatment of malignant biliary obstruction between the two groups (p = 0.848). Conclusions: Considering the cost of treatment and the burden of patients the authors recommend self-expandable metal sten timplantation if the life expectancy of patients is more...
