What are the differences between transverse and longitudinal sections of the uterine body?

Patient's question:

Since my surface skin is vertically incised. I heard that if the surface skin is vertical, the uterine body is transversely incised. Is this vertical incision of the surface skin considered part of the lower segment of the uterus? I am looking forward to your reply. Thank you!

Doctor's answer:

The horizontal and vertical incisions of cesarean section are related to aesthetics. The horizontal incision follows the direction of skin tension lines, resulting in fewer scars, better appearance, and relatively faster healing. The likelihood of uterine rupture is lower with a horizontal incision compared to a vertical one. The vertical incision is particularly quick to perform but is not as aesthetically pleasing. After a horizontal incision, pubic hair can cover the scar, making it invisible. The horizontal incision is a more aesthetically pleasing surgery, but it takes longer to perform—it involves cutting horizontally, vertically, and then horizontally, which is not as fast as the vertical incision. However, when actually cutting into the uterus, it is always the lower segment of the uterus. In emergency situations, a horizontal incision cannot be performed at all.
