“…We used the transvesical port because it is diametrically opposed to the transgastric port and seems to offer additional advantages over transvaginal and transcolonic ports. 18 In fact, although the transvesical port does not support as large instruments as transvaginal and transcolonic ports, it is sterile, available in the 2 genders and seems particularly safe, at least in a porcine model, even when left unclosed. Moreover, the bladder dome offers the most anterior position in the lower abdomen, allowing the introduction of surgical instruments above the bowel loops.…”

Purpose:Recently there has been increasing enthusiasm for performing simple abdominal procedures by transgastric surgery. We previously reported the usefulness of a combined transgastric and transvesical approach to cholecystectomy. In this study we assessed the feasibility of combined transgastric and transvesical approach for performing a more complex surgical procedure, such as nephrectomy, in a porcine model. Materials and Methods: In a nonsurvival study combined transgastric and transvesical approaches were established in 6 female pigs. Under ureteroscope guidance we installed a transvesical 5 mm over tube into the peritoneal cavity and a flexible gastroscope was passed orally into the peritoneal cavity by a gastrotomy. We performed right or left nephrectomy with instruments introduced by the 2 devices that worked in the renal hilum, alternating device intervention for dissection and retraction procedures. Results: Four right and 2 left nephrectomies were performed. There were no complications during the creation of transvesical and transgastric access. In all animals we visualized the 2 kidneys. The renal vessels and ureter were reasonably individualized and ligated separately with ultrasonic scissors, which were introduced through the transvesical port. In 2 early cases mild hemorrhage occurred after ultrasonic ligation. To overcome this complication we applied clips successfully before ultrasonic ligation in the remaining animals. Thus, complete renal release and mobilization to the stomach were achieved in all animals. Conclusions: Nephrectomy by natural orifices using the combined transgastric and transvesical approach is technically feasible, although to our knowledge there is no reliable method for removing the specimen with current instruments.

“…the Stringer Device (LSI Solutions, Victor, NY) (15), the Eagle Claw (Olympus America, Inc., Center Valley, PA) (16,17), the NDO Plicator (NDO Surgical, Mansfield, MA, USA) (18), and the three-channel device based on ShapeLock technology (USGI Medical, Inc., San Clemente, CA) (12,19). The Stringer Device is a prototype incision and closure device that was used by Fong et al to assess the transcolonic approach as a means of accessing and systematically exploring the abdominal cavity in a pig survival study design (15). After advancing the hand-activated device under visualization to the desired incision site, a purse string suture is deployed around the planned incision site using an integrated dual metal ring mechanism.…”

“…Recently, the same researchers used the transvesical port to perform thoracoscopy with lung biopsies through the diaphragm in a survival porcine model study [24]. A transcolonic port approach has also been reported involving several complications related to the nonsterile nature of the colon [25].…”

For many abdominal procedures, advantages such as minimal scarring, reduced pain, and faster recovery have made laparoscopy the favored approach over traditional open surgery. The most recent minimally invasive approach is natural orifice transluminal endoscopic surgery (NOTES), which limits morbidity because this surgery does not require incision. This article reviews the history, development, and current and future applications of NOTES in the field of urology.
