The incidence and mortality of colorectal cancer (CRC) in the Czech Republic is significant. The National CRC Screening Program started in 2000 and was further enhanced in 2009. In 2010, the European Guidelines were introduced.

Natural orifice transluminal endoscopic surgery vs laparoscopic ovariectomy: complications and inflammatory response.

Aim: To compare natural orifice transluminal endoscopic surgery (NOTES) vs standard laparoscopic ovariectomy in mini pigs with respect to technical aspects, complications and parameters of systemic inflammatory response.

Methods: This was a randomized, experimental, survival study. Ten female mini pigs underwent NOTES transgastric ovariectomy (NOTES group) and ten female mini pigs underwent laparoscopic ovariectomy (LAP group).

Training on an ex vivo animal model improves endoscopic skills: a randomized, single-blind study.

Background: Animal models are used for training of different endoscopic procedures. Whether this really improves endoscopic skills remains controversial.

Objective: To assess the effectiveness of training by using an ex vivo animal gastric model on the performance of two therapeutic procedures-hemostasis and treatment of perforation.
