“…Several studies have since used the transgastric port for intraperitoneal abdominal procedures, such as fallopian tube ligation, cholecystectomy, gastrojejunostomy, lymphadenectomy, oophorectomy, partial hysterectomy, splenectomy, appendectomy, and diaphragmatic pacing [6][7][8][9][10][11][12][13][14][15]23]. Following the initial enthusiasm, however, abdominal procedures through isolated transgastric routes raised limitations that jeopardized application in humans.…”

“…Using two endoscopes, or a single endoscope conjugated with a transabdominal trocar, Park et al [7] and Swanstrom et al [26] experienced significant difficulties performing cholecystectomy using shape-lock technology. Rolanda et al [20] introduced a combined transgastric and transvesical approach to effectively perform moderately complex upper-abdominal procedures such as cholecystectomy.…”

“…These developments marked a new era in minimally invasive abdominal surgery, compelling novel, previously audacious goals, such as avoidance of incisions and pain. With the visceral wall no longer a barrier to endoscopic intervention, various authors described novel, complex abdominal procedures [6][7][8][9][10][11][12][13][14][15][16]. In 2006, such reports motivated researchers in this emerging field to organize the Natural Orifice Surgery Consortium for Assessment and Research (NOSCAR), a joint initiative supported by the American Society for Gastrointestinal Endoscopy (AGES) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES).…”

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.

“…In 2004, Kalloo et al [1] described access to the peritoneal cavity through the transgastric port in a porcine model. Since then, several studies have been performed using transgastric access [2][3][4][5][6]. However, many limitations were described, particularly when singly performed by transgastric port.…”

Transvesical peritoneoscopy with rigid scope: feasibility study in human male cadaver

et al. 2010

View full text Add to dashboard Cite

Background Transvesical port refers to the method of accessing the abdominal cavity through a natural orifice (i.e., urethra) under endoscopic visualization. Since its introduction in 2006, various reports have been published describing different surgical interventions using a rigid ureteroscope in a porcine model. The aim of this study was to test the access and feasibility of peritoneoscopy by using a rigid ureteroscope in a human male cadaver.Methods Two adult male cadavers were used to perform the procedures. A rigid ureteroscope was used for the creation of transvesical access into the peritoneal cavity. Peritoneoscopy, liver biopsy, and identification and manipulation of the ileocecal appendix were performed. Results Transvesical access into the peritoneal cavity was quickly established. The rigid ureteroscope easily allowed visualization of the abdominal cavity with good image quality. Liver biopsy and manipulation of ileocecal appendix were carried out without difficulties. Conclusions Peritoneoscopy, liver biopsy, and ileocecal appendix manipulation using a rigid ureteroscope through a transvesical port is feasible in a cadaver model. The development of a specific rigid scope for the transvesical port might herald a promising future for this NOTES access.

“…In fact, Reddy and Rao (N. Reddy, V. G. Rao, oral communications, May 15 and 19, 2005; N. Reddy, oral communication, May 2004) and Kalloo et al [8] described a new port to the peritoneal cavity through a transgastric approach in humans and pigs, respectively. Subsequently, various authors described more-complex intra-abdominal procedures in porcine models, opening a new era in surgery that is being considered third generation surgery: the natural orifice translumenal endoscopic surgery (NOTES) [7,9,[11][12][13][14][19][20]. Building on these findings, our group described transvesical endoscopic peritoneoscopy as a complementary and safe approach to the abdominal cavity in a porcine model [10,16].…”

Transvesical thoracoscopy: A natural orifice translumenal endoscopic approach for thoracic surgery

et al. 2007

View full text Add to dashboard Cite

Background: Recently there has been an increasing enthusiasm for using natural orifices translumenal endoscopic surgery (NOTES) to perform scarless abdominal procedures. We have previously reported the feasibility and safety of the transvesical endoscopic peritoneoscopy in a long-term survival porcine model as useful for those purposes. Herein, we report our successful experience performing transvesical and transdiaphragmatic endoscopic approach to the thoracic cavity in a long-term survival study in a porcine model. Methods: Transvesical and transdiaphragmatic endoscopic thoracoscopy was performed in six anesthetized female pigs. A 5 mm transvesical port was created on the bladder wall and an ureteroscope was advanced into the peritoneal cavity. After diaphragm inspection, we introduced through the left diaphragmatic dome a ureteroscope into the left thoracic cavity. In all animals, we performed thoracoscopy as well as peripheral lung biopsy. Animals were sacrificed by day 15 postoperatively. Results: We easily introduced a 9.8 Fr ureteroscope into the thoracic cavity that allowed us to visualize the pleural cavity and to perform simple surgical procedures such as lung biopsies without complications. There were neither respiratory distress episodes nor surgical complications to report. Postmortem examination revealed complete healing of vesical and diaphragmatic holes, whereas no signs of infection or adhesions were observed in the peritoneal or thoracic cavities. Conclusion: This study demonstrates the feasibility of transvesical thoracoscopy in porcine model. However, although this study extends the potential applications of NOTES to the thoracic cavity, new instruments and further work are needed to provide evidence that this could be translated to humans and with advantages for patients.
