Q

indirect vs direct inguinal hernias?

A
  • if you place your finger over the deep inguinal ring (just above the mid-point of the inguinal ligament), then you can control an indirect inguinal hernia which has been reduced.
  • If when youpress the deep ring, thehernia still protrudes, then the hernia is emerging via a defect in the posterior wall medial to this point and is, therefore, adirect hernia.

Q

why does pregnancy increase risk of an obturator hernia?

Q

localised infection to generalized peritonitis?

A

A localised infection may develop because the infection becomes walled-off or is contained by the positioning of adjacent organs. In this situation, an abscess may develop in an attempt to control the spread of infection. If the infection spreads throughout the peritoneal cavity this leads to generalised peritonitis
