Question 2

What is wound dehiscence?

Accepted Answer

Partial or complete separation of wound edges after closure

Answer

Dehiscence is the breakdown and separation of a surgical wound, which may expose underlying tissues and require reoperation.

Question 3

Which absorbable suture is commonly used for bowel anastomosis and mucosal closures due to its predictable absorption profile?

Accepted Answer

Polyglycolic acid (Vicryl)

Answer

Vicryl (polyglycolic acid) is a synthetic absorbable suture widely used for GI anastomoses and mucosal closures because it maintains tensile strength for approximately 3 weeks.

Question 4

What is evisceration in the context of wound complications?

Accepted Answer

Protrusion of abdominal organs through a dehisced wound

Answer

Evisceration is a surgical emergency where abdominal contents (bowel, omentum) protrude through a completely dehisced wound, requiring immediate surgical intervention.

Question 5
