Prevention of adhesion to prosthetic mesh: comparison of oxidized generated cellulose, polyethylene glycol and hylan G-F 20.

Background: The aim of this study was to investigate the impact of oxidized generated cellulose, polyethylene glycol and hylan G-F 20 on adhesion formation, fibrosis and inflammation after repair of abdominal wall defect with polypropylene mesh in an animal model.

Methods: Forty rats were divided into four groups and abdominal wall defect was established. The defect was repaired with polypropylene mesh alone (control group), polypropylene mesh and hylan G-F 20 as adhesion barrier, polypropylene mesh and oxidized generated cellulose as adhesion barrier, or polypropylene mesh and polyethylene glycol as adhesion barrier in Groups I, II, III, and IV, respectively.

Gastric duplication cyst in an adult.

Gastric duplication cyst which is a rare anomaly can also be observed in adulthood. Abdominal pain is the most common complaint in adults and most cases are discovered incidentally by radiological examination or gastric endoscopy. Preoperative diagnosis of gastric duplication is difficult and definitive diagnosis requires findings on laparatomy together with histopathological examination of the lesion.
