Patient: You performed this surgery on my mom, and it’s been 15 days today, and she is recovering well from the surgery. I would like to thank Dr. Wu! The last two days have been very difficult to defecate, and it’s hard to sit down and hold it inside the anus. Is this normal or abnormal? Wu Tao, Department of General Surgery, Peking University First Hospital: Thank you for your trust! Sorry for not being able to reply in time. After rectal or sigmoid surgery, defecation will be affected to a certain extent because some physiological reflexes of defecation have changed, and patients need some time to recover. The main methods: 1, maintain a normal diet, fruits and vegetables need to eat, to prevent dry stools; 2, training bowel regularity, the early post-operative rather more often, try to avoid many days without defecation; 3, the usual training of the anal sphincter, mainly for contraction of the anus. At the same time, you can take a sitz bath with warm water to relax the muscles, after the stool or 2-3 times a day; 4, only as a last resort to use some laxatives to help defecate. I hope my answer can help! Or contact me. Patient: My mom was reviewed by you last week Friday – with the oral capsules of Roxida and did not have any reaction after using them. The only thing is that the amount of food has increased, she eats 4 or 5 meals a day, and she gets hungry after eating for a while. The blood test you gave me, when do I have to go back to you for a review? Wu Tao, Department of General Surgery, Peking University First Hospital: Sorry for the delayed reply. The laboratory tests done in the hospital were all normal, and the tumor markers were all at normal levels. It is good that there is no reaction to oral chemotherapy, but usually some symptoms will appear in the later courses; it is good that you can eat and have more strength to tolerate chemotherapy. Chemotherapy treatment schedule: after 14 days of continuous use, rest for 7 days. During these 7 days, find time to review the blood test and liver and kidney function, and continue chemotherapy if normal. Other tumor markers, ultrasound, etc. can be reviewed once every 3 months or so, depending on your schedule.
