Endoscopic ultrasound-guided radiofrequency ablation of the pancreas: An experimental study with pathological correlation.

Background: The treatment of pancreatic cancer represents a major objective in clinical research, as it still remains the fourth leading cause of cancer deaths among men and women, with approximately 6% of all cancer-related deaths.

Materials And Methods: We studied the assessment of an endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) probe through a 19G needle in order to achieve a desirable necrosis area in the pancreas. Radiofrequency ablation of the head of the pancreas was performed on 10 Yorkshire pigs with a weight between 25 kg and 35 kg and a length of 40-70 cm.

Peritoneal access, transgastric peritoneoscopy and oophorectomy - feasibility study on an experimental Swine model.

Background/aims: Natural orifice translumenal endoscopic surgery (NOTES) still poses numerous challenges, even in cases of relatively simple surgical procedures. This study aims to assess the feasibility of transgastric resectional interventions using commonly available endoscopic equipment as well as to offer a safe closure method of the gastric access site.

Methodology: Ten pigs underwent pure transgastric endoscopic oophorectomy using a single channel endoscope.

[Hydatid cyst--rare presentations].

Hydatid disease is an parasitic infestation due to germens from Echinococcus family, principal localizations of the disease being hepatic and pulmonary. We present two cases of disease, first localized primary on the buttock and second with multiple organ involving. We consider these cases interesting because of rarity and complexity of lesions.
