There are usually no sequelae after ileocecal resection, but a few patients may have adhesions, risk of infection and sequelae such as malabsorption of nutrients and diarrhea. Surgical resection of the ileocecal region will produce scar adhesions and increase the risk of adhesive bowel obstruction. Patients who feel discomfort and pain at the surgical site of the abdomen should be hospitalized as soon as possible. Postoperatively, the risk of infection can be increased. After the ileocecal flap is removed, the rapid flow of small bowel contents to the large bowel and the backflow of cecum contents into the ileum cannot be effectively prevented, which irritates the bowel wall and increases the risk of infection. Postoperatively, it can also lead to malabsorption of nutrients. The end of the ileum is the main absorption site for bile salts, internal factors and vitamin B12, and after resection of the ileocecal valve, the flow of nutrients from the ileum to the large intestine increases, and the absorption of nutrients decreases. As the function of the ileocecal valve disappears after the operation, the difference between the environment and flora in the ileum and the jejunum is narrowed, which can easily lead to the occurrence of enterocolitis, and thus diarrhea manifestation is easy to occur.
