Patient: I’ve had this surgery for two weeks, and today I removed the gauze and found that the inside of the incision, I should say inside the stomach, and I found that the incision was convex in that position. I found it only after removing the gauze. Some people say it’s because the gas inside has not yet disappeared and it will take some time. Doctor: From your description, you can see that the surgical treatment worked well, but the incision was found to be convex after two weeks. There are several complications late after appendectomy, 1, incisional infection; 2, intra-abdominal infection; 3, intestinal adhesion; 4, incisional hernia; 5, incisional scar, etc. From your description I think the situation you described may be the latter two cases, you can go to the hospital for ultrasound examination, and it is usually clear.
