We conducted a literature review of natural orifice transluminal endoscopic surgery(NOTES),focusing on urologic procedures with gastrointestinal tract access,to update on the development of this novel surgical approach.As part of the methods,a comprehensive electronic literature search for NOTES was conducted using Pub Med and Cochrane Library from March 2002 to February 2016 for papers reporting urologic procedures performed utilizing gastrointestinal tract access.A total of 11 peer-reviewed studies examining utility of gastrointestinal access for NOTES urologic procedures were noted,with the first report in 2007.The procedures reported in the studies were total/radical nephrectomy,partial nephrectomy,adrenalectomy,and prostatectomy.The transgastric approach was identified in five studies examining total/radical nephrectomy(n = 2),partial nephrectomy(n = 1),partial cystectomy(n = 1),and adrenalectomy(n = 1).Six studies evaluated transrectal approach for NOTES,describing total/radical nephrectomy(n = 3),partial nephrectomy(n = 1),robotic nephrectomy with adrenalectomy(n = 1) and prostatectomy(n = 1).Feasibility was reported in all studies.Most studies were preclinical and acute,and limited by concerns regarding restricted instrumentation and infection risk.We concluded that gastrointestinal access for urologic NOTES demonstrates promise as described by outlined feasibility studies in preclinical models.Nonetheless,clinical application awaits further advancements in surgical technology and concerns regarding infectious potential.
We conducted a literature review of natural orifice transluminal endoscopic surgery (NOTES), focusing on urologic procedures with gastrointestinal tract access, to update on the development of this novel surgical approach. As part of the methods, a comprehensive electronic literature search for NOTES was conducted using Pub Med and Cochrane Library from March 2002 to February 2016 for papers reporting urologic procedures done utilizing gastrointestinal tract access. A total of 11 peer-reviewed studies examining utility of gastrointestinal access for NOTES urologic procedures were noted, with the first report in 2007. The procedures reported in the studies were total / radical nephrectomy, partial nephrectomy, adrenalectomy, and prostatectomy. The transgastric approach was identified in five studies examining total / radical nephrectomy (n = 2), partial nephrectomy (n = 1), partial cystectomy n = 1), and adrenalectomy (n = 1). Six studies as transrectal approach for NOTES, illustrating total / radical Nephrectomy (n = 3), partial nephrectomy (n = 1), robotic nephrectomy with adrenalectomy (n = 1) and prostatectomy (n = 1). Feasibility was reported in all studies. regarding restricted instrumentation and infection risk. We noted that the gastrointestinal access for urologic NOTES demonstrates promise described by approved feasibility studies in preclinical models. Nonetheless, clinical application awaits further advancements in surgical technology and concerns for infectious potential.
