EUS training and practice patterns among gastroenterologists completing training since 1993.

BACKGROUND: EUS training and practice patterns vary widely. The aim of this study was to assess EUS training methods, volumes, and practice patterns, and to obtain subjective assessment of endoscopic competence from endosonographers. METHODS: A survey was sent to over 1400 U.S. and international gastroenterologists who completed training since 1993. We assessed demographics, whether EUS is performed, how EUS training was obtained, and volume and type of EUS procedures performed in training and at present. Subjective assessment of adequacy of training was also obtained. RESULTS: A total of 157 physicians responded, including 76 EUS performers, of whom 67% completed advanced endoscopy fellowship, 14% were EUS trained during GI fellowship, and 19% learned via other means. EUS performers were subgrouped into those who had and had not completed advanced endoscopy fellowship, and those within and outside of an academic practice. There were significant associations between the number of upper EUS, pancreaticobiliary, and EUS-guided FNAs performed during training (p < 0.001 for all 3 groups) and completion of advanced endoscopy fellowship. Physicians in academic practice performed more EUS and FNAs per month than physicians in other types of practice (p values <0.001 and 0.001, respectively); 93.3% of respondents felt they received adequate instruction in diagnostic EUS, regardless of type of training; 88.9% of EUS performers felt they received adequate instruction in performing FNA. CONCLUSIONS: Most EUS performers are in academic practice. Those with advanced training obtained higher training volumes and perform higher volumes of EUS. The majority of respondents felt well trained regardless of training type and the number of procedures performed during training. This is the first analysis to assess these aspects of EUS training and practice.

Use of expandable metallic biliary stents in resectable pancreatic cancer.

AIM: To compare the efficacy of metal versus plastic stents for biliary strictures in patients with surgically resectable pancreatic cancer. METHODS: The medical records at MD Anderson Caner Center from September 2001 to May 2004 were reviewed. Fifty-five patients were identified to have either a metal biliary stent (13 patients, group A) or a plastic biliary stent (42 patients, group B) and subsequently went to surgery. These two groups were compared with regards to number of stents placed prior to surgery, time period between the last stent and surgery, and operative and postoperative complications. RESULTS: Of the 13 patients in group A, 12 had pancreaticoduodenectomy performed and one had exploration only due to the peritoneal metastatses discovered at the time of surgery. Of the 12 patients with pancreaticoduodenectomy, 10 had pancreatic adenocarcinoma, 1 intraductal papillary mucinous tumor, and 1 ampullary cancer. Only 2 patients required an additional endoscopic retrograde cholangiopancreatography (ERCP) after initial metal stent placement until surgery. The average time between last stent placement and surgery was 106.5 days. Of the 42 patients in group B, 35 had pancreaticoduodenectomy and 7 had either palliative surgery or exploration due to metastatic diseases discovered at the time of surgery. Of the 35 patients, 27 had pancreatic adenocarcinoma, 5 ampullary cancer, 1 neuroendocrine tumor, 1 microcystic adenoma, and 1 autoimmune pancreatitis. Sixteen patients (38%) in group B required 3 or more ERCPs with plastic stents prior to surgery. The average time between last stent placement and surgery was 56.4 days. Preoperative chemoradiation was given to all 13 patients in group A and 31 of 42 patients in group B. There were no stent-related intra- or postoperative complications in both groups. Two of 13 patients (15%) with metal stents versus 39 of 42 patients (93%) with plastic stents, however, developed either cholangitis or cholestasis due to stent occlusion while waiting for surgery. CONCLUSIONS: Contrary to the belief that metal stents are contraindicated for patients with surgically resectable pancreatic cancer, our study demonstrated that metal stents provided a longer patency rate, fewer ERCP sessions, and fewer episodes of cholangitis without adding any intra- or postoperative complications. Therefore, metal stents should be considered for patients with resectable pancreatic cancer, especially if surgery is not immediately planned as more patients are now receiving preoperative chemoradiation.
