BACKGROUND With cholangiocarcinoma, the only hope of a cure is resection. This study was undertaken to determine the impact of margin status, stage, tumor location, and adjuvant therapy on survival after resection of extrahepatic cholangiocarcinoma. METHODS From 1985-2006, 91 patients underwent resections of cholangiocarcinomas. Margin status was codified(More)
Many surgeons attempting Laparo-Endoscopic Single Site (LESS) cholecystectomy have found the operation difficult, which is inconsistent with our experience. This article is an attempt to promote a standardized approach that we feel surgeons with laparoscopic skills can perform safely and efficiently. This is a four-trocar approach consistent with the four(More)
Laparoendoscopic single site (LESS) surgery promises improved cosmesis and possibly less pain. However, given the small series reported to date, true estimates of the advantages and possible disadvantages of LESS surgery remain unknown. This study was undertaken to evaluate the first 100 patients undergoing LESS cholecystectomy at our institution. Patients(More)
INTRODUCTION The expansion of robotic-assisted surgery is occurring quickly, though little is generally known about the "learning curve" for the technology with utilization for complex esophageal procedures. The purpose of this study is to define the learning curve for robotic-assisted esophagogastrectomy with respect to operative time, conversion rates,(More)
Monte Carlo production in CMS has received a major boost in performance and scale since the past CHEP06 conference. The production system has been re-engineered in order to incorporate the experience gained in running the previous system and to integrate production with the new CMS event data model, data management system and data processing framework. The(More)
BACKGROUND The antiapoptotic protein survivin has been demonstrated to play an important role in colorectal carcinogenesis. However it is unclear whether the upregulation of survivin is maintained through progressive stages of disease, or if other apoptosis-related genes are coexpressed and/or repressed. We sought to evaluate survivin expression in colonic(More)
BACKGROUND The applications of laparoendoscopic single-site (LESS) surgery, including cholecystectomy, are occurring quickly, although little is generally known about issues associated with the learning curve of this new technique including operative time, conversion rates, and safety. STUDY DESIGN We prospectively followed all patients undergoing LESS(More)
INTRODUCTION The journey from conventional "open" operations to truly "minimally invasive" operations naturally includes progression from operations involving multiple trocars and multiple incisions to operations involving access through the umbilicus alone. Laparoscopic operations through the umbilicus alone, laparoendoscopic single site surgery (LESS),(More)
Apocrine adenocarcinoma is a rare malignancy with invasive potential. Its clinical behavior and histologic appearance are highly variable, making accurate diagnosis difficult. We report on a case of apocrine carcinoma presenting with lymph node infiltration and extensive extramammary Paget's disease. Wide local excision with lymph node dissection is the(More)
BACKGROUND The association between body mass index as a measure of obesity and rectal cancer outcomes has been inconsistent. Radiologic measures of visceral adiposity using CT scans have not been well characterized among rectal cancer patients. The objective of this study was to examine quantitative radiologic measures of visceral obesity compared with body(More)
