BACKGROUND Reduction mammaplasty is the fifth most common reconstructive surgical procedure in the United States. The incidence of invasive breast cancer in breast reduction specimens is between 0.06 and 0.4 percent. However, the incidence of atypical hyperplasia and other precancerous lesions is not well described. METHODS The authors conducted a(More)
The foundation for natural orifice transluminal endoscopic surgery (NOTES) is to access the peritoneal and other body cavities through the wall of the alimentary tract via natural orifices, with the goal of performing procedures within the peritoneum and other cavities, without the need to make incisions in the abdominal wall. We have made great progress in(More)
BACKGROUND Ventral incisional hernias still remain a common surgical problem. We tested the feasibility of transvaginal placement of a large synthetic mesh to repair a porcine hernia. METHODS Seven pigs were used in this survival model. Each animal had creation of a 5-cm hernia defect and underwent a transvaginal repair of the defect with synthetic mesh.(More)
Transvaginal cholecystectomy with laparoscopic assistance has been performed safely in humans. The next goal was to develop a natural orifice transluminal endoscopic surgery (NOTES) technique to perform cholecystectomy without laparoscopic instruments using one flexible endoscope and flexible accessories. The aim of the study was to test the feasibility of(More)
BACKGROUND Currently, no endoscopic clips have been proven to be effective in ligating the cystic duct in natural orifice transluminal endoscopic surgery (NOTES) hybrid cholecystectomy. OBJECTIVE To determine the safety and feasibility of a prototype endoscopic flexible clip applier, which is the only flexible device that deploys a zero-gap clip. DESIGN(More)
BACKGROUND Adhesion-related complications after abdominal surgery result in significant morbidity and costs. Results from animal studies investigating prevention or treatment of adhesions are limited due to lack of consistency in existing animal models. The aim of this study was to compare quality and quantity of adhesions in four different models and to(More)
BACKGROUND Placement of stents may be an alternative option to treat gastrojejunal (GJ) anastomotic leaks after Roux-en-Y gastric bypass (RYGB) surgery. The aim was to evaluate the performance of a covered metal stent (Alimaxx-E, 18 x 100 mm) across a GJ leak in a porcine model. METHODS In eight pigs, a RYGB was performed and a 1-cm leak was created.
