Question

Parker-ker suture technique is used in

• A. Nerve anastomosis
• B. Intestinal anastomosis
• C. Tendon suturing
• D. Cystorrhaphy

Hint:

Remember that serosa-to-serosa contact is the gold standard for visceral healing. Suture patterns like Parker-Kerr, Lembert, Halsted, and Cushing are designed to achieve this inversion.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Suture techniques in veterinary surgery are selected based on the tissue characteristics and the necessity of preventing leakage of luminal contents in hollow organs.

Step 2: Detailed Explanation:
The Parker-Kerr suture is an inverting suture pattern used to close the ends of hollow visceral organs.
It is classically employed in intestinal surgery, such as during an end-to-end or side-to-side intestinal anastomosis, or when closing the stump of a transected intestine or uterine horn.
The technique utilizes a continuous horizontal mattress pattern over a clamp, which is then tightened as the clamp is slowly withdrawn.
This is followed by an inverting Cushings or Lembert suture line to invaginate the raw edges, ensuring a serosa-to-serosa fluid-tight seal.
Inverting patterns are critical in gastrointestinal surgery because contact between the serosal layers results in rapid fibrin deposition and healing, minimizing the risk of peritonitis.
Therefore, this pattern is not used for nerve anastomosis, tendon suturing, or routinely for cystorrhaphy.

Step 3: Final Answer:
The Parker-Kerr suture technique is specifically used in intestinal anastomosis and closing hollow viscera stumps.
