Graded Pneumatic Dilation using Rigiflex Achalasia Dilators in Patients with Primary Esophageal Achalasia 总被引:14,自引:0,他引:14
Shailesh C. Kadakia M.D. F.A.C.P. F.A.C.G. F.C.C.P. Roy K. H. Wong M.D. F.A.C.P. F.A.C.G. 《The American journal of gastroenterology》1993,88(1):34-38
Pneumatic dilation is the initial therapy for primary esophageal achalasia. Recently, polyethylene balloon (Rigiflex) dilators have been used with varying success and complication rate. We performed a total of 47 dilations in 29 consecutive patients with achalasia using the Rigiflex dilators. The 3.0-cm balloon was always used first. If there was no symptomatic response, a 3.5-cm balloon was used after 4–8 wk. If there was still no symptomatic response after 4-8 wk, a 4.0-cm dilator was used. Eighteen (62%) patients were successfully dilated with a 3.0-cm balloon only. Of 11 patients not responding to a 3.0-cm balloon, five were dilated successfully with a 3.5-cm balloon. Of six patients not responding to a 3.5-cm balloon, four were successfully dilated with a 4.0-cm balloon dilator. Two patients eventually required surgery. The overall success with Rigiflex balloon dilator was achieved in 27 of 29 (93%) patients. There were no complications. We conclude that pneumatic dilation for esophageal achalasia performed in a graded fashion starting with Rigiflex 3.0-cm balloon dilator has a high success rate without complications in patients with achalasia. 相似文献

BackgroundThe prevalence of osteoarthritis of the hallux metatarsophalangeal joint (MTPJ) is 1 in 40 people over the age of 50. Surgical treatment options for MTPJ arthritis include joint preservation, joint resurfacing, and arthrodesis. Hallux MTPJ implants have evolved over the past several decades, but are associated with various complications. The aim of this study was to examine the MAUDE database to determine reported adverse events for hallux MTPJ implants.Materials and methodsThe US Food and Drug Administration’s (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was reviewed from 2010 to 2018 to review voluntary reported adverse event reports for approved implants within the United States. We recorded the type of adverse event and excluded duplicate reports and those extracted from already published literature.ResultsAmong 64 reported hallux MTPJ implant adverse events, the most common modes of adverse events were component loosening (34%), infection (14.1%), component fracture (9.4%), inflammation (9.4%), and allergic reaction (7.8%). Regarding implant type, Cartiva SCI had the highest percentage of adverse events (23.4%), followed by Arthrosurface ToeMotion (20.3%), Ascension MGT (12.5%), Arthrosurface HemiCAP® (10.9%), Futura primus (9.4%), and Osteomed Reflexion (6.3%). There was an increase in reported adverse events after 2016. The MAUDE database does not report the total incidence of implant insertion.ConclusionOur study of the MAUDE database demonstrated that component loosening and infection are the most common modes of adverse events for hallux MTPJ implants. Cartiva accounted for one-fourth of the implant-related adverse events during our study period, followed by ToeMotion, and Ascension MGT implants. Continued reporting of adverse events will improve our understanding on short and long-term complications of various hallux MTPJ implants.Level of evidenceLevel IV; Case Series from Large Database Analysis; Treatment Study. 相似文献

The 2013 Academic Emergency Medicine consensus conference focused on global health and emergency care research. One conference breakout session discussed research ethics and developed a research agenda concerning global acute care research ethics. This article represents the proceedings from that session, particularly focusing on ethical issues related to protecting human subjects while conducting acute care research. Protecting human research subjects from unnecessary risk is an important component of conducting ethical research, regardless of the research site. There are widely accepted ethical principles related to human subjects research; however, the interpretation of these principles requires specific local knowledge and expertise to ensure that research is conducted ethically within the societal and cultural norms. There is an obligation to conduct research ethically while recognizing the roles and responsibilities of all participants. This article discusses the complexities of determining and applying socially and culturally appropriate ethical principles during the conduct of global acute care research. Using case studies, it focuses both on the procedural components of ethical research conducted outside of “Western” culture and on basic ethical principles that are applicable to all human subjects research. This article also proposes specific research topics to stimulate future thought and the study of ethics in these complex circumstances. 相似文献
