Many people have this perception: the cecum is a small intestine, sometimes lesions occur in the resection will not have too much impact. In fact, this is a misunderstanding. The cecum also has a role in removing toxins, which can purify the body. What exactly is the symptom of paracolic hernia of the appendix, below, the professional doctor to tell you about the seriousness of this condition, what are the key reasons? (A) pathogenesis There are three crypts around the ileocecal region, all of which are generally small and unlikely to form an internal hernia. If they are too large and deep, there is a possibility that the small intestine may protrude into them under increased intra-abdominal pressure, forming an internal hernia and causing complete or incomplete intestinal obstruction. (II) Pathogenesis Due to the rotation of the midgut during embryonic period, three crypts are formed in the ileocecal region, i.e., supra-ileocecal crypt, infra-ileocecal crypt and post-caecal crypt. Supra-ileocecal crypt and infra-ileocecal crypt are formed by folds of the peritoneum during the branching of ileocecal arteries, and the post-caecal crypt is due to the abnormality of the intestinal rotation process, in which, normally, the cecum rotates and descends to the right iliac fossa, and is completely attached to the posterior abdominal wall of the right iliac fossa. Under normal circumstances, the cecum rotates down into the right iliac fossa and attaches itself completely to the posterior abdominal wall of the right iliac fossa. 1, ileocaecal recess (superior ileocaecal recess), also known as the ileocecal fossa or Luschka fossa, is supplied by the ileocecal artery in front of the ileocecal conjunction of the branches of the ileocecal artery – anterior cecal artery, the peritoneal membrane is wrapped around the peritoneal folds formed in the shape of an arch-shaped peritoneal crease, known as cecal vascular folds (visceral folds), or ileocecal folds ( superior ileocaecal folds). superior ileocaecal fold) and the formation of a narrow gap; its anterior border for the cecal vascular fold, the posterior is the ileocecal mesentery, the right border is the ileocecal junction, below the end of the ileum, the mouth of the crypt opens to the left lower (Figure 1), the crypt is common in children, usually with the growth of age and become smaller, the elderly significantly reduced and often disappeared. 2, ileocaecal recess (inferior ileocaecal recess) The peritoneal folds in front of the end of the ileum in front of the appendiceal mesentery is called the ileocaecal fold or ileocaecal fold, different from the cecum vascular folds, generally does not contain blood vessels, in the ileocaecal fold (ileocaecal fold) and appendiceal mesentery in the deeper part of the interstice between the ileo-caecal fold, i.e., for the ileocaecal fossa, also known as ileocaecal fossa (Figure 1), ileocaecal fossa (figure 1). 1), the anterior border of the ileocaecal fossa is the ileocaecal fold, above it is the back of the ileum and its mesentery, on the right side is the cecum, and behind it is the upper part of the appendiceal mesentery, and the mouth of the fossa opens to the left and downward. According to statistics, about 60% to 85% of individuals have ileocecal fossa, and this fossa is more obvious in young people, and is often filled with fat as they grow older. 3.The retrocecal recess (retrocecal recess) is a gap between the back of the cecum and the posterior abdominal wall (Figure 1), about 10% of individuals have retrocecal recess, its size, range of individual varies greatly, occasionally can be extended upward to the ascending colon posteriorly for a considerable distance, and the depth of which is sufficient to allow to extend into the whole finger, the retrocecal recess anteriorly for the cecum (occasionally the lower part of the ascending colon), and the posterior border is the iliac fossa. The peritoneal wall layer, flanked by the caecal folds, also known as parietocolic folds, is a continuation of the peritoneum from the cecum to the iliac fossa, and the appendix is often located in the posterior crypt of the cecum. If the above ileocecal folds are too large and too deep, in the case of increased intra-abdominal pressure, the small intestine can be protruded into them, forming an internal hernia; and cause complete or incomplete intestinal obstruction, clinically, the intestinal tube protrudes into the ileocecal upper crypt and the ileocecal lower crypt than protruding into the posterior crypt of the caecum to form internal hernia more common. In summary, these problems are the serious causes of the disease. These causes can lead to overdrafting of the physical condition and cause malnutrition, among other reasons. Everyone is already aware of these conditions. Specialized hospital clinics will be very professional in helping people with the disease. You should go to the hospital in time, so as not to delay the condition to bring more serious pain.
