A diverticulum is a pouch-like structure formed when the mucosa of the colon protrudes outward through a weak part of the intestinal wall, and poor drainage of the diverticulum causes inflammation, called colonic diverticulitis. It is more common in middle-aged and elderly people aged 50-70 years, and more women than men. It is usually due to weakness of the intestinal wall and constipation caused by a low-fiber diet that increases intestinal pressure. Clinical manifestations of colonic diverticulitis are usually not obvious, mainly manifested as abdominal pain, accompanied by constipation, bloating and other discomfort symptoms, abdominal pain is persistent or spasmodic, stool frequency increases, stool with blood or positive occult blood. Related laboratories When patients present with colonic diverticulitis, they should promptly visit the general surgery and gastroenterology departments of hospitals to perform routine blood tests, X-ray examinations, abdominal ultrasound and abdominal CT to confirm the diagnosis. Routine blood tests may show elevated blood leukocyte count and neutrophil percentage and elevated ultrasensitive C-reactive protein; abdominal ultrasonography may reveal thickening of the intestinal wall and the presence of surrounding abscess formation; CT examination may reveal inflammatory manifestations of pericolonic fat, visible fistulas and abscesses, and barium enema may reveal the presence of diverticula. Treatment of colonic diverticulitis is usually conservative, that is, under the guidance of a doctor using anti-inflammatory drugs, such as norfloxacin, cephalosporins, etc., and drugs to regulate intestinal flora, probiotics such as bifidobacteria and other symptomatic treatment. If colonic diverticulitis is complicated by serious complications such as intestinal obstruction, peritonitis, diffuse peritonitis that produces abscess, poor drainage of abscess, persistent intestinal obstruction, fistula formation, hemorrhage, etc., which is ineffective by conservative treatment, or recurrent hemorrhage within a short period of time, surgical treatment is feasible. The company’s main goal is to provide a comprehensive range of products and services to the public. In case of fistula or obstruction, continuous gastrointestinal decompression and intravenous rehydration therapy should be performed.
