The effects of ventilation with high density oxygen on the strength of gastrointestinal anastomosis

Purpose: The aim of our study is to evaluate the effects of administration of perioperative supplemental oxygen on anastomoses. Methods: Forty male Wistar albino rats were used in the study and randomized into 4 groups. Ischemia-reperfusion models were built in groups 3 and 4. Jejunojejunostomy was performed in all rats and assigned to an oxygen/nitrous oxide mixture with a fraction of inspired oxygen of 30\% in groups 1 and 3 and 80\% in groups 2 and 4. The measurements of perianastomotic tissue oxygen pressure, bursting pressure, level of hydroxyproline were evaluated and compared in all groups. Results: The perianastomotic tissue oxygen pressures, bursting pressures and levels of hydroxyproline were identified as significantly high in groups 2 and 4, administered a fraction of inspired oxygen of 80\%, compared to groups 1 and 3, administered a fraction of inspired oxygen of 30\%. Conclusion: Perioperative supplemental oxygen contributes positively to the anastomotic healing

Changes In The Frequencies Of Abdominal Wall Hernias And The Preferences For Their Repair: A Multicenter National Study From Turkey

Abdominal wall hernias are a common problem in the general population. A Western estimate reveals that the lifetime risk of developing a hernia is about 2%.– As a result, hernia repairs likely comprise the most frequent general surgery operations. More than 20 million hernias are estimated to be repaired every year around the world. Numerous repair techniques have been described to date however tension-free mesh repairs are widely used today because of their low hernia recurrence rates. Nevertheless, there are some ongoing debates regarding the ideal approach (open or laparoscopic),, the ideal anesthesia (general, local, or regional),, and the ideal mesh (standard polypropylene or newer meshes).,PubMedWoSScopu
