BACKGROUND Laparoscopic techniques are being used increasingly in the repair of ventral hernias and offer the potential benefits of a shorter hospital stay, decreased wound complications, and possibly a lower recurrence rate. Despite good results from high-volume centers, significant complications may occur with this approach and the morbidity of incisional(More)
Experience with laparoscopic resection of pancreatic neoplasms remains limited. The purpose of this study is to critically analyze the indications for and outcomes after laparoscopic resection of pancreatic neoplasms. The medical records of all patients undergoing laparoscopic resection of pancreatic neoplasms from July 2000 to February 2006 were reviewed.(More)
BACKGROUND This study examines the impact of age and comorbidities on complications and outcomes of laparoscopic (Lap) paraesophageal hernia (PEH) repair. METHODS Data were collected prospectively on all patients who underwent Lap PEH repair from January 1995 through June 2005. Pre- and postoperative variables including complications were analyzed.(More)
Although excess visceral fat is associated with noninfectious inflammation, it is not clear whether visceral fat is simply associated with or actually causes metabolic disease in humans. To evaluate the hypothesis that visceral fat promotes systemic inflammation by secreting inflammatory adipokines into the portal circulation that drains visceral fat, we(More)
The purpose of this study is to characterize the esophageal motor and lower esophageal sphincter (LES) abnormalities associated with epiphrenic esophageal diverticula and analyze outcomes for laparoscopic esophageal diverticulectomy, myotomy, and partial fundoplication. The endoscopic, radiographic, manometric, and perioperative records for patients(More)
CONTEXT It has been hypothesized that increased plasma bile acids (BAs) contribute to metabolic improvements after Roux-en-Y gastric bypass (RYGB) surgery by the G protein-coupled receptor TGR5-mediated effects on glucagon-like peptide-1 secretion and thyroid hormones. OBJECTIVE The objective of this study was to evaluate the importance of bariatric(More)
BACKGROUND & AIMS Most patients with extreme obesity have nonalcoholic fatty liver disease (NAFLD). Although gastric bypass (GBP) surgery is the most common bariatric operation performed in obese patients in the United States, the effect of GBP surgery-induced weight loss on the metabolic and hepatic abnormalities associated with NAFLD are not clear.

The purpose of this study was to characterize the adhesion characteristics of absorbable- and nonabsorbable-barrier-coated meshes and to report adhesiolysis-related complications during laparoscopic re-exploration after prior ventral hernia repair. Under an IRB-approved protocol, patients undergoing laparoscopic re-exploration after prior intraperitoneal(More)
The purpose of this study is to determine the incidence of residual common bile duct (CBD) stones after preoperative ERCP for choledocholithiasis and to evaluate the utility of routine intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC) in this patient population. All patients who underwent preoperative ERCP and interval LC with(More)
BACKGROUND The purpose of this comparative study is to evaluate the acute fixation strength of mechanical tacking devices and fibrin sealant against polypropylene suture for laparoscopic ventral hernia repair. METHODS Three metallic mechanical tacking devices (ProTack, Salute, EndoANCHOR), 4 absorbable tacking devices (AbsorbaTack, PermaSorb, I-Clip, and(More)
