Fecal pus examination, simple examination method, intuitive results, can initially provide information on the function of the digestive tract or pathological changes, as well as indirectly determine the functional status of the gastrointestinal, pancreatic, hepatobiliary. There are many bacteria in the fecal matter. On the contrary, less systemic symptoms are more severe and less severe. Generally, the symptoms and characteristics of schistosomiasis are different, which can be severe and severe. Sigmoid colonoscopy for diffuse mucosal inflammation, ulcers of different degrees and different sizes of ulcers, flask-shaped, can be covered by blood clots, no diffuse mucosal inflammatory changes - mucosal congestion, water intestines and may have yellow small particles of chronic inflammation The ulcer is deeper.Basic Information
Specialist classification: Digestive examination classification: feces / parasitic examination
Applicable gender: whether men and women apply fasting: not fastingAnalysis results:
Not detected by the naked eye or negative by microscopy.
The stool has pus, mucus, or pus mixed with blood.
Not detected by the naked eye or negative by microscopy.Clinical significance
When there is inflammation in the lower part of the intestine, the stool has pus, or pus and mucus, pus and blood mixed together, common in dysentery, ulcerative colitis, colon cancer or rectal cancer.
Several kinds of diarrhea characterized by pus and bloody stools, bacterial dysentery, amoebic dysentery, Campylobacter enteritis, schistosomiasis, ulcerative colitis, epidemiological significance is popular, can also be distributed more scattered, low epidemic Dissemination, local epidemic has been in the epidemic area, there is a history of contact with the infected water, the appearance of feces is less, the mucus is mainly, there is a small amount of blood and feces, the feces are mixed with dark red blood and a small amount of mucus, foul odor → water Then → pus and stool will be thin, there may be pus and mucus, more feces, pus and blood mixed, mucus will have blood, odorous pH alkaline (about 8.0) acidic (6.1 ~ 6.6) - alkaline - microscopic examination of cellular components to white blood cells Mainly, a large number of neutrophils, pus cells, macrophages, epithelial cells, red blood cells are less red blood cells, more necrotic substances, visible amoeba trophozoites and Xiako-Ryden crystals visible polynuclear white blood cells and red blood cells It can be seen that red blood cells, white blood cells and schistosomiasis eggs can be seen as white blood cells and red blood cells.
The characteristics of red blood cells are fresh, not deformed, scattered in old, condensed into piles, scattered in a string like 缗 缗, scattered fresh and old, the dynamic types and quantity of fresh microscopic bacteria are reduced, the variety and quantity are more visible There are many different types of small bacilli, and there are many bacteria in the fecal matter. On the contrary, less systemic symptoms are more severe and less severe. Generally, the symptoms and characteristics of schistosomiasis are different, which can be severe and severe. Sigmoid colonoscopy for diffuse mucosal inflammation, ulcers of different degrees and different sizes of ulcers, flask-shaped, can be covered by blood clots, no diffuse mucosal inflammatory changes - mucosal congestion, water intestines and may have yellow small particles of chronic inflammation The ulcer is deeper.Positive results may be diseases: dysentery, post-dysentery syndrome, warming precautions
Requirements for inspection:
1, feces pus contains a large number of bacteria, should pay attention to seal when sending inspection, so as not to cause pollution.
