In view of the vague knowledge of many patients about anal fistula and post-surgical care and precautions, I summarize the things to pay attention to after surgery in the hope that it will be helpful to all patients. Definition of anal fistula: An infected channel between the anal canal and the perianal skin and perianal tissue gap formed from an infection of the anal glands is called an anal fistula. Anal fistulas are the inevitable result of incision and drainage or natural breakdown of a perianal abscess. Anorectal fistulas, or anal fistulas for short, account for one-quarter of all anorectal diseases and rank second only to hemorrhoids. The first is that the first day after the operation should be mainly in a flat position, the anal drain can be placed on the side, because the flat position on the incision pressure hemostatic effect is better, but also conducive to rest; try to reduce the number of times out of bed, to avoid the incision easy bleeding; bed turning movements as gentle as possible, to avoid excessive amplitude leading to the release of the dressing dressing caused by bleeding; after the operation to be anesthesia awake, if there is no nausea After the anesthesia wakes up, if there is no nausea, vomiting, you can eat a small amount of liquid food, such as white porridge and pasta. Second: On the first day after surgery, after the anal incision dressing is removed, it is not advisable to get out of bed immediately, try to lie down for one hour and observe that there is no obvious bleeding from the incision, then you can get out of bed, if the incision is large and there is more blood seepage, it is recommended to remove the anal filling dressing in stages to avoid pressure drop causing hemorrhage; on the first day after surgery, the diet is also semi-liquid as much as possible, and you can eat more vegetables and fruits to facilitate laxation. Third: On the second day after surgery, if the incision does not bleed significantly, you can exercise appropriately after meals, controlled at 15-30 minutes, to help the recovery of intestinal function and facilitate defecation; appropriate anal lifting exercise, preferably 5 groups of 50 times per day, which helps the blood circulation of the incision to promote incision healing, and also helps the functional exercise of anal muscles to promote defecation and avoid fecal incontinence; diet should be as light as possible, preferably The diet should be as light as possible, preferably with more vegetables and less meat, to help soften the stool and avoid possible bleeding after the stool. Fourth: post-operative anal swelling, tingling, itching, etc. may occur, which is a common phenomenon in the healing process of anal incision, this is a normal process, do not worry, about three to six months later, these symptoms will basically disappear; post-operative drug change process must observe the drainage of the main fistula, but also to observe the existence of branch fistula, if there is a branch fistula must be placed in time to drain the drainage strip The first thing you need to do is to make sure that you have the right amount of money to pay for your surgery. I hope the above experience will help patients in need and finally, may the world be free of fistulas.
