What Is the Caecum?

The cecum: the initial segment of the large intestine, which is also the shortest segment of the large intestine. It is about 6 to 8 cm in length and is located in the lower right part of the abdominal cavity. colon. It is the beginning of the large intestine. It is in the shape of a sac and is located in the right popliteal fossa. It is connected to the ileum. The mucous membrane at the entrance of the ileum to the cecum protrudes into the intestinal cavity, forming upper and lower lip-shaped ileocecal flaps, which can prevent the contents of the large intestine from flowing back into the small intestine.

Cecum I. Overview:

The cecum is the pouch-like portion of the large intestine. Because the distal end is occluded, it is called the cecum. A small tube protrudes from the distal end of the cecum, called the appendix. Because of its small lumen, it is easy to be blocked and inflamed. It is appendicitis, commonly known as cecumitis. The cecum, also known as the appendix, is the starting part of the large intestine. It is located in the lower right part of the abdominal cavity, just on the caudal side where the right popliteal ileum enters the large intestine. A person's cecum degenerates, the lower end is freely presented as a cecum, and it continues upwards to the ascending colon. There is a hole in the lower part through the appendix. The ileocecal flap is located on the inner side wall of the ascending colonic junction area. The flap is based on the small intestine annulus muscles and protrudes to the large intestine. It is the portal through which the small intestine passes through the large intestine. The cecum is rarely inflamed. The so-called "cecumitis" is mostly a misnomer for appendicitis. In the TCM literature "difficult classics", the cecum is called the "appendix" and is one of the seven punches.

Cecum II: Anatomy:

The cecum is the beginning of the large intestine and the shortest in the large intestine. The lower end of the cecum begins with an enlarged blunt end, which varies in length from person to person, generally about 6 to 8 cm upward, connected to the end of the ileum and continuing into the ascending colon. On the posterior medial wall of the lower end of the cecum, there is a free slender intestine, called an appendix, or a vermiform process. In general, the cecum is similar to the colon. There are also three colonic bands on the surface. They converge toward the root of the appendix and continue with the muscular layer of the appendix. Therefore, no matter how the position of the appendix changes, the root of the appendix can be found down along the colonic band. In addition, on the left posterior wall of the cecum and ascending colon phase, there is an opening at the end of the ileum, which is called the ileocecal orifice. The shape of the mouth is mostly oval-shaped fissures, and the upper and lower edges have half-moon-shaped mucosal folds, which are called colon valves. The upper edge of the fold is called the upper lip, and its attachment site is about the level between the ileum and colon. The lower edge of the fold is called the lower lip. The entire lower lip is long and depressed, and its attachment site is about the junction between the ileum and the cecum. The anterior and posterior ends of the upper and lower lips are combined with each other and extend forward and backward respectively to form a colon valve band. The various structures formed by the mucosal folds above are all related to the thickening of the circular muscle layer at the end of the ileum at the ileocecal colon. The thickened circular muscle has the function of sphincter. It can not only prevent the contents of the large intestine from flowing back to the small intestine, but also control the chyme to not enter the large intestine too quickly, so that the chyme can be fully digested and absorbed in the small intestine.

Cecum III. Diseases related to cecum and their clinical treatment:

1. Cecumitis: The name of this disease is Uyghur medicine, which is the main feature of inflammation of the cecum. Etiology of persistent constipation, intestinal obstruction often, intestinal parasites or eating fruit seeds, shelled food slides into the cecum for a long time, resulting in rotten gas damage to the cecum. Symptoms include mild fever, irritability, insomnia, nausea and bloating, vomiting, severe pain in the right abdomen, and increased pressure. You can feel lumps by touching your hand. If you are inflamed by parasites, you can find a history of deworming. Expelling the block, mainly anti-inflammatory and analgesic. Be sure to lie still, do not do much activity, and do not take various preparations orally. To open the block, 230g of olive oil plus boiling water or soapy water enema, anti-inflammatory and analgesic, hot topical, if you want to vomit, you should apply it cold; if parasitic inflammation, you should use insect repellent treatment.

Cecalitis is also called appendicitis. It is a condition formed by the inflammation of the appendix that spreads to the entire cecum. Disease name. Commonly known as cecumitis. Medically, a small tubular organ like an earthworm extending from the lower end of the cecum in the abdominal cavity of a human body is called an appendix (also called vermicular process). It is located in the right popliteal fossa, the upper end of which is connected to the posterior inner wall of the cecum and opens in the cecum. The total length is about 2-20 cm. If germs, parasites or other foreign matter enter, the appendix becomes inflamed. The main symptoms are right lower quadrant pain, nausea, and vomiting. Traditional Chinese and Western medicines are used for anti-inflammatory treatment, and patients with acute severe or repeated treatment must undergo surgical removal. In order to cause more common diseases, the patients may be life-threatening, and care must be taken to prevent them. In the article "Reorganizing the Party's Style," Mao Zedong pointed out that the purpose of rectification is to treat illness and save people, just like cutting appendicitis. It is a common abdominal disease that can be divided into acute and chronic. At the beginning of acute appendicitis, there is pain in the upper abdomen or umbilical cord, and then to the right lower abdomen. Physical examination of the right lower abdomen includes tenderness, rebound pain and muscle tension, which may be accompanied by nausea, vomiting, fever, and increased white blood cells. In severe cases, perforation of the appendix can cause appendix mass or peritonitis. Treatment includes acupuncture, Chinese medicine, antibiotics, and surgery. Chronic appendicitis often has faint and tenderness in the right lower abdomen, and can be recurrent. Surgical treatment is appropriate. Inflammation of an appendic infection located in the lower right part of the abdominal cavity. The appendix is an earthworm-like blind tube connected to the end of the cecum. Its opening is narrow, the mesangium is short and easily twisted, and it is easy to be blocked by food residues, fecal stones, foreign bodies, etc., causing secretions to escape into the cecum and causing bacterial infection and inflammation. Appendicitis is divided into acute and chronic. Acute appendicitis is the most common surgical acute abdominal disorder in young adults. The main symptom is abdominal pain. The abdominal pain of most patients begins in the upper abdomen or around the umbilicus, and after a few hours the pain turns to the right lower abdomen; followed by nausea, vomiting, general malaise, and fever. Physical examination showed marked tenderness in the right lower quadrant, severe inflammation of the right lower quadrant and rebound tenderness in the severely inflamed person, and an increase in white blood cell count on blood tests. Based on these symptoms and signs, the vast majority can be diagnosed. Of course, there are also symptoms and signs that are not typical, which makes diagnosis difficult and delays treatment. Acute appendicitis can cause severe complications such as purulent peritonitis caused by necrotic perforation, so early diagnosis and treatment should not be ignored. Chronic appendicitis is an acute appendicitis after recurrence or frequent right lower quadrant pain. Appendicitis is best treated with surgical removal of the appendix. The combination of Chinese and Western medicine with Chinese medicine, acupuncture and antibiotics can also relieve the symptoms of most patients, but there is still the possibility of recurrence. Therefore, it should be based on the disease, medical conditions and patient requirements. And other comprehensive consideration of treatment options.

CT Cecum IV. CT diagnosis of cecum cancer:

Blind ascending colon: The clinical symptoms of blind ascending colon cancer appear relatively late. Due to the relatively large intestinal cavity, large tumors often form before they are discovered. Cancers cause thickening of the intestinal wall and cause narrowing of the intestinal cavity. The narrow intestinal cavity is mostly eccentric, and the vast majority are ulcerous cancers, with Borrmann 2 cancers being the most common.

Borrmann type 1 cancer that occurs in the cecum can cause intussusception. Failure to pay attention to the manifestations of the intussusception can lead to missed diagnosis. Most tumors are located in the front of the intestine loop, showing a soft tissue density mass shadow. The side of the intestinal lumen is hemispherical, and the surface is not smooth. The enhancement of the tumor is more obvious after enhancement.

In addition to blind ascending colon cancer, lumps located in the ileocecal region should be distinguished from peripheral appendix abscesses, lymphoma, Crohn's disease, Behcet's disease, idiopathic ulcers, and intestinal tuberculosis.

The clear relationship between lesions and ileocecal valves during reading is of great value in differential diagnosis.
