Final answer:
The woman with constant drainage from a non-healing abdominal wound most likely has a fecal fistula, which is an abnormal connection that has formed between the bowel and the abdominal wall.
Step-by-step explanation:
The woman who fell from a truck and developed constant drainage from a non-healing wound on the surface of her abdomen is experiencing symptoms that suggest she has developed a fecal fistula. A fistula is an abnormal connection between two parts of the body, such as between the bowel and the abdominal wall in this case, through which fluids can pass. This complication can occur after abdominal surgeries where there has been injury to the intestines. Typically, treatment involves surgical repair of the bowel, protection of the skin around the fistula, and management of the fluid output. The constant drainage and non-healing nature of the wound are key indicators of a fistula rather than an abscess, hematoma, or seroma, which present differently.
