Patients with pain on the right side of the stomach, the common clinical causes are mainly the following cases. First, patients with gallbladder stones accompanied by cholecystitis will have obvious pain in the right side of the abdomen with muscle tension. At this time, the severity of the patient’s lesion can be clarified through ultrasound examination, and timely anti-infection, antispasmodic and analgesic treatment can be given to relieve the inflammation of the gallbladder. Patients are recommended to undergo cholecystectomy electively, which can avoid recurrent attacks of local pain. Second, patients with ileal malignant tumor, once intestinal obstruction occurs, will cause pain symptoms on the right side of the stomach. At this time, the patient will be accompanied by obvious abdominal distension, anal stopping exhaustion and defecation. It is suggested that the patient should undergo radical resection of tumor and lymph node dissection in time, which can achieve certain therapeutic effect after surgery. Once the stone is embedded in the ureter, it will cause ureteral dilatation and fluid accumulation, which can also cause pain on the right side of the stomach, and the stone can be discharged smoothly by extracorporeal impact lithotripsy to relieve the symptoms of pain on the right side of the stomach.
