Objective: The 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. Methods: Changes 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. Results: Both 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). Conclusions: Both 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. [ABSTRACT FROM AUTHOR]

Objectives: To analyze risk factors of post-ERCP pancreatitis (PEP) in high risk patients in whom prophylactic pancreatic stents (PPSs) were intended to use to prevent endoscopic retrograde cholangiography (ERCP)-related complications. Patients and methods: Three hundred and seventeen high-risk patients for developing PEP were considered for preventive pancreatic stent placement in our endoscopy unit over 5 years. 5 Fr, 3–5 cm long PPSs were used. All data were collected in a predefined database. Development of PEP despite PPS placement was analyzed. Results: PEP occurred in 29 of 288 successfully stented patients (10.07%; 24 mild, four moderate, one severe). PPS was protective against all risks factors except for sphincter of Oddi dysfunction (SOD). PPS related complication rate was 2.78% (n = 8). Unsuccessful stenting occurred in 29 patients (9.15%), PEP developed in 41.38% (n = 12; seven mild, four moderate, one severe). Those patients who had more patient related risk factors were more likely to develop PEP despite preventive measures with PPS. On the contrary, PPS placement was less successful in patients who had more procedure related risk factors. Conclusions: PPS is protective against all risks factors of PEP except for SOD in high-risk patients. More vulnerable patients who have more patient-related risk factors are more likely to develop PEP despite PPS is used, while more complex procedures predispose to unsuccessful PPS placement in patients with more procedure-related risk factors. PPS insertion in high-risk patients is effective and safe preventive method and the procedure related complication rate is reasonably low. [ABSTRACT FROM AUTHOR]

Összefoglaló. Bevezetés: Az epeúti kövesség meglétének valószínűsége különböző klinikai prediktorok alapján megbecsülhető, e faktorok szenzitivitása és specificitása azonban nem kielégítő. Az endoszkópos ultrahangvizsgálat az epeúti kövesség diagnosztizálásának szemiinvazív precíz eszköze. Célkitűzés: Célunk az endoszkópos ultrahangvizsgálat diagnosztikus érzékenységének vizsgálata gyanított epeúti kövesség esetén. Módszer: A prospektív vizsgálat során a betegeket az Amerikai Emésztőszervi Endoszkópos Társaság (ASGE) ajánlása szerint meghatározott prediktorok alapján közepes és magas valószínűségi csoportokba osztottuk, és endoszkópos ultrahangvizsgálatot, valamint amennyiben szükséges volt, endoszkópos retrográd kolangiopankreatográfiát (ERCP) végeztünk. Eredmények: Összesen 95 beteget vizsgáltunk. Az endoszkópos ultrahangvizsgálat 53 (56%) beteg esetében írt le epeúti kövességet: 55%-ban (39/71) a közepes valószínűségi és 58%-ban (14/24) a magas valószínűségi csoportban. Az ERCP mindegyik choledocholithiasisos esetet megerősítette. A két valószínűségi csoport között nem volt szignifikáns különbség (p = 0,56) az ERCP által igazolt epeúti kövesség tekintetében. Az ERCP csupán 1 esetben detektált epeúti kövességet a negatív endoszkópos ultrahangvizsgálat ellenére. Az endoszkópos ultrahangvizsgálat specificitása 100%, szenzitivitása 98%, míg pozitív és negatív prediktív értéke 100%, valamint 98% volt. Megbeszélés: Az epeúti kövesség meglétének becslése különböző klinikai prediktorok alapján kihívást jelenthet. Következtetés: Az endoszkópos ultrahangvizsgálat szenzitív és pontos diagnosztikus eszköz a choledocholithiasis kimutatására és értékelésére, olyan esetekben is, amelyeknél az előzetes képalkotók nem találtak kövességet. Orv Hetil. 2022; 163(10): 400-406., Introduction: The likelihood of common bile duct stones can be prognosticated by various clinical predictors, however, the sensitivity and specificity of these factors are moderate. Endoscopic ultrasonography has been shown to be a semi-invasive precise test for the detection of common bile duct stones., Objective: Our aim was to assess the diagnostic accuracy of endoscopic ultrasonography in patients with suspected choledocholithiasis., Method: Patients of this prospective study were categorized and divided into intermediate likelihood and high likelihood groups according to the clinical predictors defined by the American Society of Gastrointestinal Endoscopy (ASGE) guidelines and referred for linear endosonography. Endoscopic retrograde cholangiopancreatography (ERCP) was performed if needed., Results: A total of 95 patients were assessed. Common bile duct stones were detected by endoscopic ultrasonography overall in 53 (56%) patients: 55% (39/71) in the intermediate likelihood and 58% (14/24) in the high likelihood group of patients. The detected common bile duct stones in all patients were confirmed by ERCP. There was no significant difference (p = 0.56) in the detection of stones by ERCP between the two likelihood groups. ERCP confirmed choledocholithiasis only in one patient whose preceding endosonography did not detect stone. The specificity and sensitivity of endoscopic ultrasonography were 100% and 98%, the positive predictive value and negative predictive value were 100% and 98%, respectively., Discussion: Estimating the likelihood of choledocholithiasis based on various clinical predictors might be challenging., Conclusion: Endoscopic ultrasonography is a highly sensitive and accurate diagnostic tool for the detection and evaluation of common bile duct stones also in patients with previous normal imaging findings.

Összefoglaló. Bevezetés: Az endoszkópos retrográd cholangiopancreatographiát (ERCP) követő pancreatitis (PEP) incidenciája a magas kockázatú betegcsoportban 14,7%. Célkitűzés: A munkacsoportunk által szerzett tapasztalatok elemzése. Módszerek: A profilaktikus pancreassztentes (PPS), magas kockázatú betegek adatait tartalmazó prospektív adatbázisunkat elemeztük retrospektív módon. Az adatokat a PEP-incidencia és a súlyosság tekintetében összehasonlítottuk a korábbi, hasonlóan magas kockázatú, sztent nélküli beteganyagunkkal, illetve a sztenteléssel kapcsolatos szövődményeket és a különböző sztenttípusokat is elemeztük. A Cotton-kritériumok szerint értékeltük a PEP-t. Eredmények: A 317, magas kockázatú betegből 288 esetben (90,9%) volt sikeres a PPS-implantáció. A sztent nélküli kontrollcsoportba 121, magas kockázatú beteget választottunk be. A sikeresen sztentelt betegekben a PEP incidenciája 10,0% volt. Ez és a PEP súlyossága (enyhe: 8,3%, középsúlyos: 1,4%, súlyos: 0,3%) is szignifikánsan alacsonyabb volt a PPS nélküli beteganyaghoz (PEP: 31,4%, enyhe: 15,7%, középsúlyos: 10,7%, súlyos: 5,0%) és a sikertelenül sztentelt betegekhez (PEP: 41,3%, enyhe: 24,1%, középsúlyos: 13,8%, súlyos: 3,4%) képest. Az utóbbi két csoport közötti különbség nem volt szignifikáns. A sztenttel kapcsolatos szövődmények közül a leggyakrabban a korai sztentkicsúszást (5/288 beteg, 1,74%) és a proximalis sztentmigrációt (3/288 beteg, 1,04%) észleltük. A sztenttípusok közül a legkedvezőbb mellékhatás-profilúnak a Freeman-típusú, belső füllel és külső "pigtail" véggel ellátott sztenteket találtuk. Következtetés: A profilaktikus pancreassztentelés hatékonyan csökkenti a PEP incidenciáját, és a súlyosságát az enyhébb esetek felé tolja el. Alkalmazása viszonylag egyszerű, azonban ismerni kell használatának megfelelő technikáját, időben történő eltávolításának és a szövődmények felismerésének fontosságát. Eredményeink és a nemzetközi ajánlások alapján magas PEP-rizikójú betegekben a PPS rutinszerű alkalmazása minden ERCP-laborban ajánlott. Orv Hetil. 2021; 162(1): 31-38., Introduction: The most frequent complication of endoscopic retrograde cholangiopancreatography (ERCP) is post-ERCP pancreatitis (PEP). Its incidence in the high-risk patient population is 14.7%., Objective: To analyze 10 years experiences of our working group., Methods: We retrospectively analyzed our prospective database of high-risk patients treated with prophylactic pancreatic stents (PPS) including the period between 2009 and 2014. We compared PEP incidence and severity findings with our historical data of pre-PPS period of similarly high-risk patients (no-stent group), furthermore analyzed the complications of PPS insertion and different stent types. PEP was defined and categorized according to the Cotton criteria., Results: In 317 high-risk patients, PPS implantation was successful in 288 cases (90.9%). The no-stent group comprised of 121 patients. Incidence and the severity of PEP in the successfully stented group (all: 10.0%; mild: 8.3%, moderate: 1.4%, severe: 0.3%) were significantly lower compared to the no-stent group (all: 31.4%; mild: 15.7%, moderate: 10.7%, severe: 5.0%) and the unsuccessfully stented group (all: 41.3%; mild: 24.1%, moderate: 13.8%, severe: 3.4%). The difference between the latter two groups was not significant. Only early dislodgment (5/288 patients, 1.74%) and proximal migration (3/288 patients, 1.04%) were observed as stent-related complications. Freeman type (single inner flange, outer pigtail end) stent was the best based on the complication profile., Conclusion: Prophylactic pancreatic stenting effectively lowers the incidence and severity of PEP. We should recognize the proper technic of its application and the importance of proper timing of its extraction and identification of complications. Utilization of PPSs in high-risk patients is strongly recommended in every ERCP center. Orv Hetil. 2021; 162(1): 31-38.

Gastrointestinal bleeding has a profound impact on public health due to its high prevalence and severity. With the elderly population taking more anticoagulants/antiaggregants/non-steroid anti-inflammatory drugs, the digestive bleeding will certainly raise more and more challenges in quantity as well as in severity for the public healthcare system. The emergency medicine specialists and gastroenterologists have a central role in the management of patients presenting with gastrointestinal bleeding. In certain cases, radiologists, invasive radiologists, intensive care specialists and surgeons should also be involved in the decision making process and management of patients. Therefore, Hungarian experts felt the need to elaborate a comprehensive, multidisciplinary, practical local guideline reflecting the frequently arisen aspects based on current international guidelines. This guideline proposal covers topics of basic requirements, initial assessment of patients, risk evaluation, laboratory tests, hemodynamic resuscitation in the case of gastrointestinal bleeding followed by its consecutive steps of diagnosis and therapy sorted by location of the source of the hemorrhage. The authors give practical instructions for unsuccessful hemostasis or rebleeding. Finally, the role of surgery is also summarized in the management of gastrointestinal bleeding.

Introduction: Sphincter of Oddi dysfunction usually occurs after cholecystectomy, but it can sometimes be detected in patients with intact gallbladder too. The diagnostic value of the non-invasive functional tests is not established in this group of patients and the effects of sphincterotomy on transpapillary bile outflow and gallbladder motility are unknown., Aims: The aim of this study was to determine the effect of endoscopic sphincterotomy on the gallbladder ejection fraction, transpapillary bile outflow and the clinical symptoms of patients with acalculous biliary pain syndrome., Patients and Methods: 36 patients with acalculous biliary pain syndrome underwent quantitative hepatobiliary scintigraphy, and all of them had decreased cholecytokinin-induced gallbladder ejection fraction. The endoscopic manometry of the sphincter of Oddi showed abnormal sphincter function in 26 patients who were enrolled the study. Before and after endoscopic sphincterotomy all patients had ultrasonographic measurement of cholecystokinin-induced gallbladder ejection fraction with and without nitroglycerin pretreatment and scintigraphy was repeated as well. The effects of sphincterotomy on gallbladder ejection fraction and transpapillary biliary outflow were evaluated. In addition, changes in biliary pain score with a previously validated questionnaire were also determined., Results: All 26 patients had decreased gallbladder ejection fraction before sphincterotomy measured with scintigraphy (19+18%) and ultrasound (16+9.7%), which was improved after nitroglycerin pretreatment (48.2+17%; p<0.005). Detected with both methods, the ejection fraction was in the normal range after sphincterotomy (52+37% and 40.8+16.5%), but nitroglycerin pretreatment failed to produce further improvement (48.67+22.2%, NS). Based on scintigraphic examination sphincterotomy significantly improved transpapillary biliary outflow (common bile duct half time 63±33 min vs. 37±17 min; p<0.05). According to results obtained from questionneries, 22 of the 26 patients gave an account of significant symptom improvement after sphincterotomy., Conclusions: Endoscopic sphincterotomy improves cholecystokinin-induced gallbladder ejection fraction, transpapillary biliary outflow as well as biliary symptoms in patients with acalculous biliary pain syndrome and sphincter of Oddi dysfunction. Cholecystokinin-induced gallbladder ejection fraction with nitroglycerin pretreatment, measured with ultrasonography can be useful to select a subgroup of patients who can benefit from sphincterotomy.
