Summary

Malignant gastric outlet obstruction is a very disabling complication of patients with gastric, duodenal, ampullary, pancreatic, or bile duct cancer and worsens their prognosis. Current treatments have reported a similar complication rate and higher mortality in surgically treated patients. Recently, the creation of endoscopic ultrasound-guided gastroenterostomy (EUS) has shown promising results in these patients. The aim of this research is to determine the safety and efficacy of EUS-guided gastro-enterostomy in the treatment of patients with malignant gastric outlet obstruction.

Detailed description

Malignant gastric outlet obstruction is a very disabling complication that occurs in 15% to 25% of patients with gastric, duodenal, ampullary, pancreatic, or bile duct cancer and worsens their prognosis. Roux-en-Y gastrojejunostomy is considered the gold standard treatment with technical success of 98.6% (97-3% -99.9%) and clinical success of 80.1% with patency of 169.2 (136.8-201.7) days. On the other hand, the technical success reported for self-expanding metal stents is 96.2% (94.1% vs. 98.4%), technical success is 79.4%, and patency at 6 months was only 57%. However, complications occur in a similar way in both forms of treatment (major complications in 6% and late complications in 17% in both, but mortality is higher in the group treated with Roux-en-Y gastrojejunostomy (29% vs. 17%). , p \<0.001) Recently, the creation of endoscopic ultrasound-guided gastroenterostomy has shown success rates of over 90% in case series, but prospective studies evaluating the safety and efficacy of the procedure are lacking. The aim of this research to determine the safety and efficacy of EUS-guided gastro-enterostomy in the treatment of patients with malignant gastric outlet obstruction.

Conditions

• Malignant Gastric Outlet Obstruction

Interventions

Type	Name	Description
PROCEDURE	EUS-guided gastroenterostomy	First after an upper endoscopy is performed, a catheters passed throughout the endoscope channel and with x-ray verification, a guide wire is passed up to the third portion of duodenal loop. then small intestinal is filled with saline solution up to 1500cc and contrast solution. Then an endoscopic ultrasound examination will be carried out where a loop of the small intestine that is located less than 2 cm apart from the gastric wall will be looked for. Once the intestinal loop is identified a direct antegrade puncture will be performed with a luminal apposition prosthesis release system . Finally, correct position is verified with x-ray and we will look for any misplacement or leakage during this process or the presence of bleeding. Endoscopic treatment will be performed if necessary. Subsequently, the participants will go to monthly follow-up with clinical evaluation, laboratory and radiological test will be carried out until the participants dies.
