Sutures and Wound Repair/ General Surgery (ABSA) Practice Test

Why is silk not recommended for use in the gallbladder, kidney, or bladder?

1. It absorbs too quickly

2. It may become a nucleus for stone formation

3. It is too thick for these organs

4. It cannot be sterilized properly

The correct answer is: It may become a nucleus for stone formation

Silk is a natural fiber that is known for its relatively good tissue handling properties, but it poses significant risks in certain anatomical locations, such as the gallbladder, kidney, or bladder. The primary reason for not using silk in these areas is that it may become a nucleus for stone formation. Silk’s surface characteristics can allow for the accumulation of mineral deposits and other materials that can lead to the formation of stones. In the gallbladder, for example, the presence of sutures might foster the development of gallstones, which can result in complications such as obstruction or infection. Similarly, in the kidney and bladder, the potential for stone formation can result in urinary tract obstructions and other serious renal concerns. Understanding this risk is essential in surgical practices, as the goal is to minimize complications and promote optimal healing. The other options revolve around different attributes of silk, but they do not address the predominant concern of foreign body reaction and stone aggregation, which is critical in the management of patients undergoing surgeries involving these organs.
