Dietary care for postoperative constipation or diarrhea: After the operation, patients are generally required to start defecating around 48 hours, once a day, and the stool should be soft and paste-like to avoid damage and increased pain caused by friction when the stool is discharged through the trauma. If there is no bowel movement for 3 days after surgery, the patient is instructed to increase some foods containing vegetable fats, such as sesame, broth, etc. A small amount of sesame oil or honey can also be taken with boiling water at night before bedtime, and after the above dietary therapy, the stool can generally be discharged. If it cannot be discharged, a small enema with open cork can be used.
