Is colonoscopy necessary in addition to stool test for diagnosing dysentery?

Stool examination for dysentery should be followed by colonoscopy. Dysentery is an intestinal infectious disease caused by Shigella infection, primarily manifested by symptoms such as fever, abdominal pain, diarrhea, and tenesmus. Patients may have a history of dysentery and show positive results in stool examination. Colonoscopy, an essential auxiliary examination for diagnosing intestinal diseases, can observe lesions in the colon and rectum. If a patient has a history of dysentery and positive stool examination results, colonoscopy is usually required to further confirm the diagnosis. During colonoscopy, the intestinal tract can be cleaned and disinfected through the scope, which aids in disease diagnosis. Besides colonoscopy, the diagnosis should also consider the patient's clinical symptoms if the stool examination is positive.

Acute dysentery typically presents with symptoms like fever, abdominal pain, and diarrhea. Antibiotic treatment can be prescribed, such as Cefixime Granules or Levofloxacin Hydrochloride Capsules.

Chronic dysentery often manifests as abdominal pain, diarrhea, and mucous bloody stool. Oral medications like Berberine Tablets or Gegen Qinlian Tablets can be prescribed for treatment.

If the patient experiences severe diarrhea, it is crucial to replenish fluids to prevent dehydration. Patients with dysentery should actively seek treatment to prevent disease progression or recurrence. In daily life, attention should be paid to food hygiene and personal hygiene, avoiding the consumption of unclean or raw and cold foods.
