BACKGROUND Surgical revision for weight regain after Roux-en-Y gastric bypass (RYGB) has been tempered by the high complication rates associated with standard approaches. Endoluminal revision of stoma and pouch dilation should intuitively confer a better risk profile. However, questions of clinical safety, durability, and weight loss need to be answered. We(More)
BACKGROUND As the field of natural orifice translumenal endoscopic surgery (NOTES) expands, new access sites are being investigated. One access site to the peritoneal cavity, which has not been the subject of much investigation, is transrectal access. The aim of this article is to describe a new method to peritoneal access: transrectal endoscopic(More)
Single-incision laparoscopic surgery (SILS) has been proposed as a minimally invasive technique with the advantages of smaller external scars and reduced pain. Furthermore, usage of the flexible endoscope for SILS in lieu of the standard laparoscope provides distinct visualization advantages. This video shows a single-incision cholecystectomy performed(More)
BACKGROUND Single-incision laparoscopic and natural orifice translumenal endoscopic surgery (NOTES) are technically challenging methods. Robotics might have the potential to overcome such hurdles with computer technology. METHODS The da Vinci Standard and S System (Intuitive, Sunnyvale, USA) were used in human cadavers and pigs to perform single-incision(More)
Natural orifice surgery has evolved from a preclinical setting into a common occurrence at the University of California San Diego (UCSD). With close to 40 transvaginal cases, we have become comfortable with this technique and are exploring other indications. One of the perceived advantages in natural orifice surgery is the potential reduction in the(More)
Surgery is moving towards less invasive and cosmetically superior approaches such as single incision laparoscopy (SIL). While trans-umbilical SIL is gaining popularity, incisions may lead to post-operative deformations of the umbilicus and the possibility of an increased rate of incisional hernias. Access within the pubic hairline allows preservation of the(More)
BACKGROUND Patient satisfaction after percutaneous endovascular procedures is significantly influenced by the amount of time to ambulation postprocedure. The purpose of this study was to assess the complication rates of early ambulation after use of closure devices or topical hemostatic agents for femoral access sites for endovascular procedures. METHODS(More)
Natural orifice translumenal endoscopic surgery (NOTES) has the potential to decrease the burden of an operation on a patient. Limitations of the endoscopic platform require innovative solutions to provide retraction and create an operation comparable with the gold standard, laparoscopic cholecystectomy. Four patients underwent transvaginal cholecystectomy.(More)
Transvaginal cholecystectomy has been performed at several institutions using hybrid natural orifice translumenal endoscopic surgery (NOTES) techniques. A 42-year-old woman with symptomatic cholelithiasis was taken to the operating room for transvaginal cholecystectomy after giving informed consent. A single 5-mm laparoscope was placed at the umbilicus,(More)
