The total length of normal adult small intestine is about 4 to 4.5 meters. The first 3/5 is jejunum and the second 2/5 is ileum. The main function of jejunum is to absorb nutrients in food, while the function of ileum is to absorb water. Because the complete loss of ileum will inevitably lead to the disorder of water and salt metabolism that is difficult to correct, it is necessary to keep enough ileum in small intestine resection. Therefore, if the patient's intestinal segment is the small intestine, then the rest must be the ileum. This situation will not have any impact no matter what diet is adopted in the future, because the patient's intestinal absorption function has basically lost.
The length of the colon is more than one meter. If the intestinal segment is colon, it will not have any special influence on the patient. However, if you want to take the method of strengthening diet to accelerate the recovery of patients, it is basically ineffective. This is because the repair of surgical trauma is a completely automatic process for the body. As long as the patient's nutritional status is not extremely poor, his recovery time is basically constant and will never change because of the quality of his diet. Taking the wound repair after appendicitis operation as an example, from the observation results of hundreds of appendix operations I have done in the past, no matter how patients eat after operation, the initial healing time of the wound is about seven days. It has long been a knowledge that patients need to make up for it by strengthening diet after operation, so that patients can recover as soon as possible, but the actual effect can only be regarded as a psychological comfort at best.
Of course, as long as the patient has an appetite after surgery, making the food that the patient wants to eat in a different way can at least make the patient have a good mood, as long as it is not too difficult to digest and not too greasy. As for the amount of each meal, it should be controlled in the range of 100 g to 200 g at first, eat more meals and less, and gradually increase after two to three days.
