Mortality in patients with unresectable gastric cancer complicated with tumor bleeding.

Background: gastric cancer (GC) is a gastrointestinal (GI) neoplasia which often complicates with GI bleeding. It is uncertain if bleeding worsens mortality in this group of patients.

Aims: to compare 30- and 90-day mortality in patients with unresectable GC (uGC) and tumor bleeding versus patients with the same neoplasia without bleeding.

Risk factors associated to argon plasma coagulation treatment failure in patients with chronic radiation proctopathy.

Background: argon plasma coagulation (APC) is the current endoscopic treatment of choice for patients who develop chronic radiation proctopathy. The aim of this study was to identify risk factors associated with treatment failure.

Methods: one hundred and ninety-nine patients treated with argon plasma coagulation in a single center were retrospectively analyzed.
