Endoscopic stenting for gastroduodenal outlet obstruction of a malignant origin, real life experience in a single center.

Aim: to evaluate the safety and effectiveness of self-expandable metal stent placement for malignant gastric outlet obstruction (GOO).

Methods: a retrospective, analytic cohort study at a single, tertiary-care center.

Results: thirty-six patients that underwent stent placement for GOO of malignant origin were identified during the study period.

Surgical Trauma Caused by Different Abdominal Access Routes-Comparison of Open Surgical, Laparoscopic, and NOTES Transgastric Techniques in a Porcine Model.

Background: Investigations indicate that natural orifice translumenal endoscopic surgery (NOTES) procedures induce a less pronounced postoperative inflammatory response than open or laparoscopic surgery, inflicting less trauma. In NOTES procedures, no skin incision is performed. We compare the inflammatory response added by the type of incision by measuring C-reactive protein (CRP) and tumors necrosis factor-alfa (TNF-α).

Initial experience with EUS-guided cholangiopancreatography for biliary and pancreatic duct drainage: a Spanish national survey.

Background: EUS-guided cholangiopancreatography (ESCP) allows transmural access to biliopancreatic ducts when ERCP fails. Data regarding technical details, safety, and outcomes of ESCP are still unknown.

Objective: To evaluate outcomes of ESCP in community and referral centers at the initial development phase of this procedure, to identify the ESCP stages with higher risk of failure, and to evaluate the influence on outcomes of factors related to the endoscopist.

A new in vivo method for testing closures of gastric NOTES incisions using leak of the closure or gastric yield as endpoints.

Background: We developed a non-survival in vivo model for testing of gastric natural orifice translumenal endoscopic surgery (NOTES) closures based on the gastric yield pressure. The aim of this study was to test our model comparing different endoscopic closure techniques with surgical closure of a NOTES gastric incision.

Methods: Laparotomy was performed in 30 pigs.

[Natural orifice transluminal endoscopic surgery (NOTES): initial experimental results].

Introduction: The advent of natural orifice endoscopic surgery (NOTES) and new prototypes for performing this surgical procedure led us to design an experimental animal surgical programme.

Material And Method: NOTES was performed over a period of one year, in sows, following the European guidelines on the use of experimental animals. Ninety operations were performed with no animals surviving.
