ABSTRACT

Natural orifice transluminal endoscopic surgery (notes), is a novel approach to the peritoneal cavity, that has been used for both diagnostic and surgical procedures. Aims: to evaluated the safety and feasibility of per-oral transgastric route for peritoneal approach and for several basic surgical techniques in a porcine experimental model. Material and methods: five pigs entered in the study. Under general anesthesia , a conventional endoscope was passed into the stomach, the gastric wall was punctured by mean of a sphincterotome and the size of the gastric incision was increased with a cholecystectomy and intestinal loops mobilization were attempted. Gastric incision closure was performed with endoloops. Results: a good observation of the peritoneal cavity was achieved. Liver samples were obtained in all procedures as well as mobilization of small intestinal loops. Cholecystectomy was possible in only three cases. Conclusion: transgastric approach to the peritoneal cavity seems to be a potential alternative to the classical laparotomy and laparoscopic technique.


La cirugía endoscópica transluminal por orificios naturales (NOTES) es un nuevo abordaje a la cavidad peritoneal que ha sido utilizada ya sea como procedimiento diagnóstico o quirúrgico. Objetivos: Evaluar la seguridad y factibilidad de la ruta per-oral transgástrica para el acceso a la cavidad peritoneal , y para la realización de técnicas quirúrgicas básicas en un modelo experimental porcino. Material y métodos: Se utilizaron cinco cerdos. Bajo anestesia general mediante un endoscopio convencional se accedió al estómago y se puncionó la pared gástrica mediante un papilótomo. La abertura se amplió ya sea con papilótomo o con balón. Se exploró la cavidad peritoneal y se intentó realizar: biopsias hepáticas en todos los procedimientos, lo mismo ocurrió con la movilización de asas intestinales. La colecistectomía fue posible en sólo tres ocasiones. Conclusión: el abordaje transgástrico de la cavidad peritoneal pareciera ser una potencial alternativa a la laparotomía clásica y laparoscópica.
