Referral Patterns for Endocrine Surgical Disease

ObjectiveReferrals between physician specialties are common practice, and clear patterns develop. The increasing availability of high-volume endocrine surgery subspecialists with better outcomes may change these patterns. This study aimed to determine what factors influence endocrinologists’ referral patterns for the surgical treatment of endocrine disease.MethodsA national, cross-sectional, voluntary survey of members of the American Association of Clinical Endocrinologists examined physician demographics, physician’s opinions on referral to endocrine surgery, preferred surgeon specialty, knowledge about surgeon characteristics, and how these factors influenced which surgeons they referred patients, as well as what changes in these factors would alter their referral patterns.ResultsThe survey response rate was 15% (73/500), and 97% were endocrinologists. On average, 0 to 5 patients/ week were referred for surgery. Most respondents (91.8%) felt that endocrinologists should decide which surgeon to refer. General surgery was the preferred surgeon specialty (43.7%), and endocrine surgery was the preferred subspecialty (70.8%). The factors most often cited as very important in referral to a surgeon included surgeon outcome/ complications (71%), familiarity with surgeon (65%), surgeon’s communication with referring physician (61%), and surgeon volume (59%). The factors most often cited as likely to change physician referral patterns included patient satisfaction (62%), complication rates (57%), surgeon outcomes (54%), and surgeon volume (50%). The factors most often cited as unlikely to change referral patterns included new surgeon availability (70%) and hospital/surgeon advertising (58%).ConclusionReferring physicians want experienced endocrine surgeons with high operative volumes and good outcomes whom they are familiar with. The promotion of referral to high-volume surgeons requires communication, good outcomes, and satisfied patients. (Endocr Pract. 2014;20:571-575)     

冠状动脉CT造影对冠心病的临床诊断价值研究

目的：探讨研究冠状动脉CT造影检查对冠心病的临床诊断价值。方法：收集我院2012年1月至2013年10月共计70例临床怀疑为冠心病的患者,对这些患者分别进行冠状动脉CT造影检查和数字减影冠状动脉造影（DSA）检查,记录这两项检查所得结果及数据,以检查数据为基础对冠状动脉CT造影和数字减影冠状动脉造影检查的临床实验效果进行对比研究。结果：70例病人均可顺利完成以上两种检查,按照数字减影冠状动脉造影检查的标准,冠状动脉CT造影的敏感度为92.2%,特异度为97.4%、阳性预测率为90.5%、阴性预测率98%。结论：相对于数字减影冠状动脉造影检查,冠状动脉CT造影检查是一种更加安全、可靠、无创且更具临床指导意义的检测技术,因此可以推荐作为冠心病诊断的首选方法。

选择性冠状静脉动脉化搭桥术中不同移植物的应用疗效比较

目的:对比选择性冠状静脉动脉化(SCVBG)搭桥治疗弥漫性右冠状动脉狭窄病变中选择乳内动脉和大隐静脉作为桥血管的治疗效果。方法:选择2008年10月到2014年10月在我院行SCVBG搭桥的84例患者资料,其中选择大隐静脉作为桥血管进行冠状静脉动脉化搭桥患者46例(大隐静脉桥组),选择乳内动脉作为桥血管进行冠状静脉动脉化搭桥患者38例(乳内动脉桥组)。随访记录两组患者的生存情况、近期复查超声心动图、冠状动脉CTA及心绞痛复发率。结果:乳内动脉桥组患者总生存率(100%)明显高于大隐静脉桥组(82.6%)(P0.05)。乳内动脉桥组患者桥血管和心中静脉通畅率(100%)明显大于大隐静脉桥组(54.35%)(P0.05)。两组患者左心室射血分数(LVEF)较治疗前明显增加,左心室舒张期末内径(LVEDD)较治疗前明显减小(P0.05)。治疗后,乳内动脉桥组患者心绞痛复发率明显小于大隐静脉桥组(P0.05)。结论:SCVBG搭桥治疗弥漫性右冠状动脉狭窄病变中,选择乳内动脉桥效果优于大隐静脉桥,能明显提高桥血管和心中静脉通畅率,降低心绞痛复发率。     

Coronary Artery Disease with Single Coronary Artery

The authors have reviewed the literature in search of the coexistence of single coronary artery with significant coronary artery disease. Two cases of single right coronary artery are described. In both, the anomalies were unsuspected and diagnosed roentgenographically in life. Both patients had angina pectoris, positive graded-exercise stress tests, and hemodynamically significant obstruction or occlusion to the coronary arteries. In neither case was the stenosis proximal or amenable to bypass surgery.
