Which core task involves tying knots inside the abdomen using instruments?

• A. Intracorporeal suturing and knot tying.
• B. Peg transfer.
• C. Pattern cutting.
• D. Extracorporeal knot tying.

Answer: (A)

Tying knots inside the abdomen using instruments is intracorporeal suturing and knot tying. In this approach, the surgeon uses laparoscopic instruments to drive the needle, approximate tissue, and form knots entirely within the peritoneal cavity, without bringing the knot outside. This differs from extracorporeal knot tying, where knots are formed outside the body and then advanced into place. Peg transfer and pattern cutting involve manipulating objects and cutting tissue, respectively, rather than suturing and knot tying inside the abdomen.
