Self-expanding metal stents versus antrectomy for the palliative treatment of obstructive adenocarcinoma of the gastric antrum.

Background: gastric cancer patients are first diagnosed with an unresectable tumor in up to 40% of cases. Gastric outlet obstruction causes nausea, vomiting, dehydration and malnutrition. The aim of the study was to compare self-expanding metal stents to antrectomy and Roux-en Y gastrojejunostomy for palliation of obstructive adenocarcinoma of the gastric antrum.

Argon plasma coagulation and hyperbaric oxygen therapy in chronic radiation proctopathy, effectiveness and impact on tissue toxicity.

Background: chronic radiation proctopathy (CRP) is associated with recurrent rectal bleeding and transfusional requirements. Argon plasma coagulation (APC) and hyperbaric oxygen therapy (HOT) have been shown to be effective in the control of CRP. No prospective comparisons have been reported between these treatments.
