1Radiofrequency ablation for treatment of hypersplenism: A feasible therapeutic option显示文摘We present a case of a patient with hypersplenism secondary to portal hypertension due to hepato-splenic schistosomiasis, which was accompanied by severe and refractory thrombocytopenia. We performed spleen ablation and measured the total spleen and ablated volumes with contrast-enhanced computed tomography and volumetry. No major complications occurred, thrombocytopenia was resolved, and platelet levels remained stable, which allowed for early treatment of the patient's underlying disease. Previous work has shown that splenic radiofrequency ablation is an attractive alternative treatment for hypersplenism induced by liver cirrhosis. We aimed to contribute to the currently sparse literature evaluating the role of radiofrequency ablation(RFA) in the management of hypersplenism. We conclude that splenic RFA appears to be a viable and promising option for the treatment of hypersplenism.Guilherme Lopes P Martins Joao Paulo G Bernardes Marcello S Rovella Raphael G Andrade Publio Cesar C Viana Paulo Herman Giovanni Guido Cerri Marcos Roberto Menezes 2015World Journal of Gastroenterology2015,21,20:17
2Encapsulating peritoneal sclerosis显示文摘Encapsulating peritoneal sclerosis(EPS) is a debilitating condition characterized by a fibrocollagenous membrane encasing the small intestine, resulting in recurrent small bowel obstructions. EPS is most commonly associated with long-term peritoneal dialysis, though medications, peritoneal infection, and systemic inflammatory disorders have been implicated. Many cases remain idiopathic. Diagnosis is often delayed given the rarity of the disorder combined with non-specific symptoms and laboratory findings. Although cross-sectional imaging with computed tomography of the abdomen can be suggestive of the disorder, many patients undergo exploratory laparotomy for diagnosis. Mortality approaches 50% one year after diagnosis. Treatment for EPS involves treating the underlying condition or eliminating possible inciting agents(i.e. peritoneal dialysis, medications, infections) and nutritional support, frequently with total parenteral nutrition. EPSspecific treatment depends on the disease stage. In the inflammatory stage, corticosteroids are the treatment of choice, while in the fibrotic stage, tamoxifen may be beneficial. In practice, distinguishing between stages may be difficult and both may be used. Surgical intervention, consisting of peritonectomy and enterolysis, is timeconsuming and high-risk and is reserved for situations in which conservative medical therapy fails in institutions with surgical expertise in this area. Herein we review the available literature of the etiology, pathogenesis, diagnosis, and treatment of this rare, but potentially devastating disease.Christopher J Danford Steven C Lin Martin P Smith Jacqueline L Wolf 2018World Journal of Gastroenterology2018,24,28:13

4Endoscopic ultrasound-guided celiac plexus neurolysis using a reverse phase polymer显示文摘AIM:To assess the feasibility of endoscopic ultrasound(EUS)guided celiac plexus neurolysis(CPN) using a poloxamer. METHODS:In this prospective evaluation,six Yorkshire pigs underwent EUS-guided CPN.Three received an injection of 10 mL of 0.25%Lidocaine plus methylene blue(group 1) and three received an injection of 10 mL of 0.25%Lidocaine plus blue colored poloxamer(PS137-25)(group 2) .Necropsy was performed immediately after the animals were sacrificed.The abdominal and pelvic cavities were examined for the presence of methylene blue and the blue colored poloxamer.RESULTS:EUS-guided CPN was successfully performed in all 6 pigs without immediate complication.Methylene blue was identified throughout the peritoneal and retroperitoneal cavity in group 1.The blue colored poloxamer was found in the retroperitoneal cavity immediately adjacent to the aorta,in the exact location of the celiac plexus in group 2.CONCLUSION:EUS-guided CPN using a reverse phase polymer in a non-survival porcine model was technically feasible.The presence of a poloxamer gel at the site of the celiac plexus at necropsy indicates a precise delivery of the neurolytic agent.Keith L Obstein Fernanda P Martins Gloria Fernández-Esparrach Christopher C Thompson 2010World Journal of Gastroenterology2010,16,6:3
5厚皮拉伸盐构造运动中上覆层构造影响因素分析显示文摘理论分析表明 ,盐撤量与拉伸造成的空间之间的平衡是决定拆离滑脱形变完全与否的控制因素。当盐撤量大于同期形成的拉伸空间时 ,上覆层发生完全拆离滑脱形变 ;反之 ,则发生非完全拆离滑脱形变。分析模拟表明 ,盐层越厚、岩盐粘滞度越小及上覆前构造层越厚 ,盐撤量就越大 ,完全拆离滑脱形变过程持续得也越久 ;区域拉伸和基底断层位移速率越大及基底断层下降盘越长 。戈红星 Bruno C Vendeville Martin P A Jackson 2003石油学报2003,24,5:3
6Percutaneous transluminal angioplasty balloons for endoscopic ultrasound-guided pancreatic duct interventions显示文摘BACKGROUND Endoscopic ultrasound(EUS)-guided main pancreatic duct(PD)access may be used when conventional endoscopic retrograde cholangiopancreatography(ERCP)techniques fail.The use of a percutaneous transluminal angioplasty balloon(PTAB),originally developed for vascular interventions,can be used to facilitate transmural(e.g.,transgastric)PD access and to dilate high-grade pancreatic strictures.AIM To describe the technique,efficacy,and safety of PTABs for EUS-guided PD interventions.METHODS Patients who underwent EUS with use of a PTAB from March 2011 to August 2021 were retrospectively identified from a tertiary care medical center supply database.PTABs included 3-4 French angioplasty catheters with 3-4 mm balloons designed to use over a 0.018-inch guidewire.The primary outcome was technical success.Secondary outcomes included incidence of adverse events(AEs)and need for early reintervention.RESULTS A total of 23 patients were identified(48%female,mean age 55.8 years).Chronic pancreatitis was the underlying etiology in 13(56.5%)patients,surgically altered anatomy(SAA)with stricture in 7(30.4%),and SAA with post-operative leak in 3(13.0%).Technical success was achieved in 20(87%)cases.Overall AE rate was 26%(n=6).All AEs were mild and included 1 pancreatic duct leak,2 cases of post-procedure pancreatitis,and 3 admissions for post-procedural pain.No patients required early re-intervention.CONCLUSION EUS-guided use of PTABs for PD access and/or stricture management is feasible with an acceptable safety profile and can be considered in patients when conventional ERCP cannulation fails.Jad P AbiMansour Barham K Abu Dayyeh Michael J Levy Andrew C Storm John A Martin Bret T Petersen Ryan J Law Mark D Topazian Vinay Chandrasekhara 2022World Journal of Gastrointestinal Endoscopy2022,14,8:2
