Answer:
"Gustavo is having an operation in the area across his abdomen and must follow the instructions after the operation is complete."
Step-by-step explanation:
As shown in the question above, Gustavo underwent a transabdominal operation, ie Gustavo underwent surgery on the abdomen. As the abdomen is a delicate and widely used region of the human body, Gustavo's doctor provided some instructions that Gustavo should follow during the postoperative period that would ensure that he had a good recovery and no further health problems. Based on this, we can conclude that the statement that best explains this scenario is "Gustavo is having an operation on the abdomen area and should follow the instructions after the operation is completed."
