Bloating and pain after minimally invasive appendicitis surgery may be caused by normal phenomenon, abdominal infection, weakened intestinal peristalsis and other reasons. 1. Normal phenomenon: there will be normal pain in the abdominal incision in the short term after minimally invasive appendicitis surgery, and due to the short-term intestinal paralysis after anesthesia, and the pneumoperitoneum established in the minimally invasive surgery will lead to abdominal distension. Therefore, mild abdominal distension after minimally invasive appendicitis surgery may be normal. 2. Abdominal infection: In minimally invasive appendicitis surgery, the infection foci are not cleaned up or the infection spreads, which will lead to abdominal infection and cause peritonitis, resulting in symptoms of abdominal distension after minimally invasive appendicitis surgery. 3. Weakened intestinal peristalsis: After minimally invasive appendicitis surgery, intestinal peristalsis may be weakened, resulting in increased intestinal gas accumulation, causing the symptoms of abdominal distension. Therefore, after the minimally invasive appendicitis surgery stomach distension pain should go to the hospital in a timely manner to improve the examination, clear the cause of the disease and then give targeted treatment.
