80% of rectal cancers have been misdiagnosed as hemorrhoids

Xiao Wang is a handsome young man who just turned 30 this year.
Under the repeated persuasion of the anorectal doctor, I reluctantly came to our endoscopy center for colonoscopy
Before the examination, Xiao Wang didn't care, and said swearingly, "I am a hemorrhoid.
As a result, the mirror just entered 10 cm, and I saw the following:
At that time, a poorly differentiated invasive carcinoma was considered, and the pathological result came out: "(10 cm from the rectum) small cell malignant tumor, tending to be poorly differentiated carcinoma, further classification by immunohistochemistry

Not to mention, how Xiao Wang's wife faced this result, and how embarrassing the three-year-old son is.
Hemorrhoids and rectal cancer can both cause blood in the stool
Hemorrhoids are venous masses formed by varicose veins in the lower rectum, anal canal and anal border.
Hemorrhoids are venous masses formed by varicose veins in the lower rectum, anal canal and anal border.
Therefore, its bleeding is mainly caused by various reasons (such as sedentary, weakened immunity, long-term oral anticoagulants, drinking, spicy stimulation, etc.
Rectal cancer is a malignant tumor and is the "abnormal tissue" of the human body
Therefore, the source of bleeding is mostly caused by cancer infiltrating the rectal mucosa and causing the surface ulceration or the ulceration of the cancer itself

Hemorrhoids in the stool are characterized by bleeding during or after defecation, bright red in color , as shown in the figure:
Hemorrhoids are divided into internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, anal fissures, etc.
External hemorrhoids generally do not bleed, internal hemorrhoids bleed but generally not painful, most of them are spotting, linear, or jet-like, and the color is mostly bright red.
Sometimes there is a small amount of blood on the surface of the stool or the toilet paper is dyed red, and sometimes it is dripping blood, and bleeding after defecation Stop on your own

Rectal cancer bleeding is characterized by the mixture of blood and stool, and the blood in the stool is dark red, also known as jam-like stool , as shown in the figure:

In addition to blood in the stool, hemorrhoids also have the following symptoms:

① Internal hemorrhoids prolapse:

Secondary internal hemorrhoids are accompanied by prolapse of defecation, which can be recovered on their own after defecation;In the third stage, it cannot be recovered by itself, and it must be recovered by hand, and it can even come out when exerting force or coughing
.

②Pain: Internal hemorrhoids are generally pain-free, but severe pain may occur if the internal hemorrhoids are incarcerated (that is, they are "stuck" in the anus and cannot be returned to the anus after prolapse)
.
.
③ Anal itching
.
The internal hemorrhoids of the third stage and above can cause dampness and itching around the anus due to the relaxation of the sphincter muscle and the secretion of intestinal secretions

Digital anal examination
Digital anal examination
General digital rectal examination is very important, because most hemorrhoids and rectal cancer occur in the areas that can be touched by the fingers
.
.
If you use your fingers to touch it from the anus, you feel that there are soft protrusions inside, and the mucosal nodules with smooth and non-tender surfaces are hemorrhoids
.
.
If you feel that there are irregularly shaped cauliflower lumps with uneven edges and uneven surfaces or ulcers with raised edges and depressions in the center, and you find that the intestinal lumen is narrow enough to accommodate only one finger;
If you feel that there are irregularly shaped cauliflower lumps with uneven edges and uneven surfaces or ulcers with raised edges and depressions in the center, and you find that the intestinal lumen is narrow enough to accommodate only one finger;After the examination, those with blood and mucus on the fingertips are very likely to suffer from rectal cancer

Colonoscopy
Colonoscopy
Secondly, doctors need to use special inspection equipment, such as bell mouth anoscope, electronic proctoscope, electronic colonoscopy, etc.
These inspections require the patient to defecate or even clean the intestines in order to distinguish whether it is hemorrhoids or tumors under direct vision
