The development of gastroparesis is closely related to genetic factors. Genealogical studies show that relatives of people with chronic digestive gastroparesis have a 2.5-3 times greater chance of developing gastroparesis than the general population. And gastroparesis can be triggered by a variety of diseases, which is a cause for concern for patients. Acute appendicitis, in particular, can be particularly distressing when it strikes. Therefore, it is especially important to treat stomach cramps as early as possible. The examination items for stomach cramps caused by acute appendicitis: 1. Blood count The increase in white blood cell count in patients with acute appendicitis, accounting for about 90% of patients, is an important basis for clinical diagnosis. It is usually in the range of (10-15) × 109/L. As inflammation increases, the leukocyte count increases and may even exceed 20 × 109/L. However, in elderly and frail patients or those with suppressed immune function, the leukocyte count does not necessarily increase. In conjunction with an increase in leukocyte count, there is an increase in neutrophil count (about 80%). The two are often seen together, but there is also a significant increase (>80%) in the ratio of neutrophils only, which is of equal importance. When the disease is progressing, the symptoms are worsening, and the already increased white blood cell count suddenly decreases, it is often a manifestation of sepsis, which is a critical sign and should be taken seriously. 2, urine routine The urine examination of patients with acute appendicitis is not special, but it is still necessary to routinely examine urine in order to exclude urological diseases that resemble the symptoms of appendicitis, such as ureteral calculi. Occasionally, if the distal appendix is inflamed and adheres to the ureter or bladder, a small amount of red and white blood cells may appear in the urine, which should not be confused with stones. 3, abdominal radiographs Acute appendicitis without complications may be completely normal on radiographs and have no diagnostic significance. In the case of complications of limited or diffuse peritonitis, the following can be found: ① pneumatization of the intestinal cavity and liquid gas planes in the right lower abdomen at the end of the cecum and ileum; ② scoliosis of the lumbar vertebrae and the shadow of the right psoas major muscle are blurred; ③ appendiceal fecal stones are sometimes seen; ④ soft tissue masses in the right lower abdomen are set off by the surrounding inflatable intestinal curves, and the edges can be relatively clear; ⑤ pneumoperitoneum due to perforation is extremely rare; ⑥ dilatation of the transverse colon can help diagnose and exclude ureteral stones (5) pneumoperitoneum due to perforation is extremely rare; (6) dilatation of the transverse colon can help diagnose and exclude ureteral calculi, intestinal obstruction and other possibilities, but the specificity is poor.
