The pain in the stomach is accompanied by significant vomiting and no diarrhea. The patient may also have vomiting of obvious gastric contents or bloody coffee-like fluid, unless it is caused by gastric dilatation. Patients with gastric ulcers in the acute phase should opt for gastrointestinal decompression, spasm relieving medications, and intravenous fluid replacement. In addition, there are patients with simple intestinal spasm or incomplete intestinal obstruction, so they present with abdominal pain, abdominal distension, nausea, vomiting, and stopping the defecation from the anus. The cause of intestinal obstruction is mainly due to laparotomy, which leaves behind fibrous strips or adhesion bands that affect the peristaltic function of the intestine and the downward advancement of intestinal contents, so they will present with obstruction, and if necessary Surgical treatment is required.
