  13. 13. Contents can not reduced back to abdomen<br />Causes:<br />- Adhesions<br />- Large contents and narrow neck<br />IRREDUCIBLE HERNIA<br />
  14. 14. Hernia content balloons over external ring when reduction is attempted. <br />
  15. 15. Obstructed Hernia<br />Irreducible hernia with obstructed intestinal lumen without interference with blood supply<br />Clinically ----- colic, constipation, vomiting, .......<br />Sometimes it is difficult to differentiate from strangulation so it is better to be managed as strangulated hernia <br />
  16. 16. Strangulated hernia<br />= Serious impairment of blood supply of the contents with or without obstruction ----- ischemia ----- if not treated within 5-6 hrs ------ gangrene<br />In strangulation venous impairment occurs first ---- intestinal congestion & edema ------- more congestion &edema ----- arterial impairment ------ ischemia ---- exudation of blood into the sac + bacterial transudation through the wall ( infected toxic fluid in the sac ) ------ gangrene ----- perforation <br />
