BACKGROUND The aim of this study was to examine whether midline, paramedian, or transverse incisions offer potential advantages for abdominal surgery. DATA SOURCES We searched MEDLINE, Embase, Web of Science, and The Cochrane Central Register of Controlled Trials from 1966 to 2009 for randomized controlled trials comparing incision choice. METHODS We(More)
BACKGROUND Complete resection of hilar cholangiocarcinoma (HCCA) is a critical determinant of long-term survival. This study validates a previously reported preoperative clinical T staging system for determining resectability of HCCA. STUDY DESIGN Consecutive patients with confirmed HCCA treated over an 18-year period were included. Patient demographics,(More)
BACKGROUND Management options for symptomatic and infected walled-off pancreatic necrosis (WOPN) have evolved over the past decade from open surgical necrosectomy to more minimally invasive approaches. We reported the use of a combined percutaneous and endoscopic approach (dual modality drainage [DMD]) for the treatment of symptomatic and infected WOPN,(More)
UNLABELLED Intraductal papillary neoplasm of the bile duct (IPNB) is a variant of bile duct carcinoma characterized by intraductal growth and better outcome compared with the more common nodular-sclerosing type. IPNB is a recognized precursor of invasive carcinoma, but its pathogenesis and natural history are ill-defined. This study examines the(More)
BACKGROUND The optimum approach to neoadjuvant therapy for patients with borderline resectable pancreatic cancer is undefined. Herein we report the outcomes of an extended neoadjuvant chemotherapy regimen in patients presenting with borderline resectable adenocarcinoma of the pancreatic head. METHODS Patients identified as having borderline resectable(More)
OBJECTIVE We have previously demonstrated that P. aeruginosa can have profound effects on the intestinal epithelial barrier via one of its virulence factors, the PA-I lectin/adhesin. The aims of the present study were to further characterize the interaction of P. aeruginosa and the intestinal epithelium using both in vitro and in vivo approaches. METHODS(More)
BACKGROUND Lymphangiogenesis, the formation of lymphatic vessels, has not been reported in engineered tissue. The purpose of this study was to characterize lymphangiogenesis in tissue-engineered small intestine. METHODS Biodegradable polymer scaffolds seeded with intestinal organoid units were implanted into syngenic recipient rats. Twenty-three(More)
BACKGROUND AND AIMS Glucagon-like peptide 2 (GLP-2) is an endogenous hormone with potent and specific intestinotrophic activity in vivo and in vitro. The aim of this study was to define the initial signal transduction mechanisms mediating the proliferative actions of GLP-2 on intestinal epithelial cells. METHODS The proliferative actions of GLP-2 on the(More)
After massive small bowel resection (MSBR), the remnant small intestine adapts to restore Na absorptive function. The possibility that this occurs through increases in cellular Na absorptive capacity was examined by assessing the regional effects of 50% proximal MSBR on the function and expression of the apical membrane Na/H exchangers (NHEs) NHE2 and NHE3.(More)
BACKGROUND/PURPOSE Hilar cholangiocarcinoma (HCCA) is a rare cancer with a low resectability rate, frequent recurrence after resection and an overall poor outcome. It is widely accepted that en bloc partial hepatectomy is a necessary part of the surgical therapy, but controversy surrounds other areas, including extent of lymphadenectomy and preoperative use(More)
