Tensile strength of wound after laparoscopic cholecystectomy in a 30 years old woman depends upon –
**Core Concept**
The tensile strength of a wound refers to its resistance to rupture or disruption. In the context of laparoscopic cholecystectomy, the tensile strength of the wound is influenced by the healing process, which involves the deposition of collagen fibers and the remodeling of the extracellular matrix.
**Why the Correct Answer is Right**
The tensile strength of a wound after laparoscopic cholecystectomy is primarily determined by the synthesis and remodeling of collagen fibers. This process is mediated by fibroblasts, which produce collagen and other extracellular matrix components. The rate and extent of collagen synthesis and remodeling are influenced by various factors, including the presence of growth factors, such as transforming growth factor-beta (TGF-β), and the mechanical properties of the wound environment.
**Why Each Wrong Option is Incorrect**
**Option A:** While wound tension can affect the healing process, it is not the primary determinant of tensile strength in this context.
**Option B:** The presence of sutures or staples can provide initial stability to the wound, but they do not directly influence the tensile strength of the wound.
**Option C:** Wound infection can compromise the healing process and reduce the tensile strength of the wound, but it is not a primary determinant of tensile strength.
**Clinical Pearl / High-Yield Fact**
The tensile strength of a wound typically reaches 70-80% of its maximum value within 3-4 weeks after surgery, with complete remodeling and maximum tensile strength achieved after 6-12 months.
**Correct Answer:** C. Wound healing.
