It is a representative disease of acute abdomen and can be caused by various factors, but 60% of them are caused by adhesions. At the beginning of the disease, there are anatomical and functional changes in the obstructed intestinal segment, followed by loss of body fluids and electrolytes, impaired circulation in the intestinal wall, necrosis and secondary infections, which can eventually lead to toxemia, shock and death. Of course, if timely diagnosis and active treatment can be made, most of them can reverse the development of the disease to cure. Therefore, for intestinal obstruction, it is important to confirm the diagnosis and treatment at an early stage.
The main pathophysiological changes of intestinal obstruction are loss of distended body fluids and electrolytes, as well as infection and toxemia. The severity of these changes varies depending on the height of the obstruction, the duration of the obstruction, and the presence or absence of blood supply disorders in the intestinal wall. Therefore, once intestinal obstruction is diagnosed, gastrointestinal decompression is a necessary emergency management measure for intestinal obstruction.
The basic treatment for small intestinal obstruction includes: gastrointestinal decompression, correction of water and electrolyte disorders and acid-base imbalance, prevention and control of infection and poisoning, and non-surgical treatment such as surgery or Chinese herbal medicine, raw vegetable oil, acupuncture and acupoint injection to release the obstruction.
However, there are many drawbacks of traditional therapy for small intestinal obstruction, including: 1. The ordinary gastrointestinal decompression tube, due to its short length, only attracts in the gastric cavity, so it can only attract the accumulated liquid and gastric juice in the stomach, but cannot directly attract the fluid and gas trapped in the small intestine, especially the trapped material in the low small intestine, so the small intestinal obstruction in a slightly lower position, the simple gastric tube decompression, cannot reach the site of obstruction and cannot well Therefore, for small intestinal obstruction in a slightly lower position, simple decompression of the gastric tube cannot reach the site of obstruction and cannot attract the trapped food and gas well, so that the obstruction cannot be resolved. Therefore, the relief rate of intestinal obstruction is low. At the same time, the highly distended intestinal canal has the destruction of intestinal mucosal barrier, and the wall of intestinal canal shows serious ischemia, which is very easy to cause the displacement of bacteria and even the occurrence of enterogenic endotoxemia, resulting in a vicious circle that cannot be interrupted and aggravating the damage to the body.
2.The treatment period of traditional conservative therapy is long, while surgical treatment is likely to cause re-adhesion to form obstruction; 3.It is impossible to determine the specific site of obstruction; 4.It is impossible to determine whether there is complete obstruction.
In order to solve these treatment difficulties, our hospital has newly developed the catheter therapy for small intestine obstruction. The features of this therapy in treatment are: 1. Direct decompression in the upper part of the intestinal obstruction facilitates the attraction of retained food and gas, thus helping to resolve the obstruction.
2. Chinese herbs and raw vegetable oil can be injected through the intestinal catheter to act directly on the upper part of the obstruction, which facilitates the resolution of the obstruction.
3.Compared with traditional therapy, it has the characteristics of short treatment period, quick effect and little trauma.
4.Even if the obstruction is complete, the catheter decompression treatment of intestinal obstruction can reduce the dilatation and edema of the small intestine above the obstruction, reduce the intraoperative contamination, and facilitate the release of adhesions and surgical anastomosis, and also facilitate the laparoscopic surgery.
5.For intestinal obstruction with serious adhesions and repeated adhesions, not only can intestinal catheter be used for preoperative decompression, but also intraoperative intestinal alignment to avoid recurrence of postoperative obstruction.
6.By means of abdominal plain film, intestinal obstruction catheter can help determine the specific site of obstruction and provide convenient conditions for surgical resolution of obstruction.
7.By injecting contrast agent into the catheter of intestinal obstruction, it can help to determine whether the obstruction is complete, which is conducive to early determination of whether surgery should be performed, thus reducing complications such as intestinal necrosis.
