Patient: description of the disease (onset time, main symptoms, hospital, etc.): abdominal pain, do the cesarean section, diagnosed as appendiceal stump inflammation, discharged from the hospital a week after the operation, the incision has two stitches has been painful, go to the hospital to check that the incision in the recovery period, normal, and now two months the incision grows well inside the pain, the ultrasound done, the abdomen has two sinus tracts, a hospital said that surgery, a hospital said that six months after the operation can be restored and so on the fever I’m not sure if I’ll be able to do it again. I would like to ask, sinus tract without surgery can slowly recover? General Surgery Department of the First People’s Hospital of Huainan, Wu Zhonghan: Hello, Ms. Feng! I would like to explain appendicitis first. The so-called appendiceal stump infection is caused by the appendix being removed with the stump retained for too long, resulting in the formation of a “small appendix”. If the ultrasound is accurate, it is necessary to determine whether the sinus tract is connected to the intestinal canal, and this can be done with a colonic iodine angiogram. If the sinus tract is connected to the intestinal canal, then the healing of the incision is pseudo-healing, the sinus tract will eventually break through the skin and connect to the outside world, thus forming a typical intestinal fistula. Appendicitis surgery as a result of intestinal fistula generally have a small impact on the body, if you can keep the drainage open, the wound clean, strengthen the nutritional support therapy, as long as the distal intestinal tube is open, intestinal fistula can be healed. If you still can’t heal, then the next step must be considered surgical treatment.
