Examination of gastroesophageal reflux by transabdominal ultrasound: can a slow, trickling form of reflux be responsible for reflux esophagitis?
The observations above may indicate a special form of gastroesophageal reflux, namely, a slow, trickling form of it. It can be responsible for the development of GERD. Fast reflux and immediate clearance are common; however, this special trickling form was observed only in GERD patients. This may explain a number of often contradictory measurements and can make the effect of cisapride more understandable. A test meal is always necessary to distinguish a bilious reflux from an acidic one, because only the latter may require aggressive antacidic treatment.
Global oxidative stress and anastomotic intimal hyperplasia are increased, and endothelialization of prosthetic grafts is significantly reduced in rabbits fed a high-cholesterol diet. Antioxidant treatment improves EC coverage and decreases intimal hyperplasia. Reducing oxidative stress may promote healing of prosthetic grafts.
