Transvesical peritoneoscopy with rigid scope: feasibility study in human male cadaver
- 104 Downloads
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.
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.
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.
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.
