Whether intestinal obstruction is dangerous depends on the actual individualized level.

If the obstruction has progressed to symptoms of peritonitis, and if intestinal necrosis cannot be ruled out, not performing timely exploratory laparotomy surgery could potentially endanger the patient's life.

However, if it is just a mild incomplete obstruction, with signs of passing gas and stools, and the patient’s abdominal symptoms are not pronounced, and related examinations are not concerning, then the risk to the patient might be relatively smaller.

Therefore, in such cases, it is not possible to generalize, and decisions need to be made based on the individual situation.

Do intestinal obstructions cause vomiting?

The typical four major symptoms of intestinal obstruction are pain, vomiting, bloating, and constipation. Vomiting refers to the urge to vomit; however, it does not mean that every patient with an obstruction must exhibit symptoms of vomiting, as the symptoms vary depending on the location of the obstruction. Obstructions can be categorized into lower and upper types. Upper obstruction may present more apparent vomiting symptoms, while lower obstruction might lead to significant bloating but less obvious vomiting. Therefore, vomiting is not a necessary symptom for the treatment of intestinal obstruction, but it can help in assessing the condition of the obstruction.

Enema method for intestinal obstruction

Enemas are an effective treatment measure in the management of intestinal obstruction. An enema involves a nurse using an enema bag to introduce about 500 milliliters of soapy water through a rounded-tip catheter into the rectum via the anus. Typically, the catheter is inserted about 30 centimeters deep. The purpose of injecting soapy water into the rectum is to stimulate intestinal peristalsis, leading to the expulsion of intestinal contents. During this process, it is important to avoid damage to the intestinal mucosa and consider the patient's tolerance. Generally, it is preferable to retain the soapy water for an extended period for better results.

Causes of intestinal obstruction

The causes of intestinal obstruction include factors external to the intestine and those originating from the intestine itself. External factors are mainly adhesions and bands of adhesions that cause intussusception or volvulus, thereby leading to intestinal obstruction. Congenital adhesive bands are common in children. Adhesions resulting from abdominal surgery or intra-abdominal inflammatory lesions are the most common causes of adult intestinal obstruction, although a minority of patients may have no history of abdominal surgery or inflammation. Additionally, incarcerated external or internal hernias may also cause intestinal obstruction. Furthermore, tumors external to the intestine or abdominal compression can also lead to obstruction.

Early symptoms of intestinal obstruction

What are the early symptoms of intestinal obstruction? For intestinal obstruction, the symptoms that appear in the early stages vary depending on the location of the obstruction. If it is a high-level obstruction, the main early symptoms are nausea and vomiting. If it is a low-level obstruction, abdominal distension is more prominent early on, and nausea and vomiting are less common. Additionally, the cause of the obstruction also leads to different symptoms. For instance, if the obstruction is simply due to adhesions in the abdominal cavity, the early symptoms may include poor appetite or nausea and vomiting. If it is caused by tumors in the digestive tract, early symptoms might include abdominal bloating, difficulty defecating, bloody stools, or changes in the characteristics of the stool, among others.

How long to fast for intestinal obstruction

Intestinal obstruction and the barrier to the passage of intestinal contents can lead to intestinal obstruction, typically characterized by abdominal pain, bloating, cessation of passing gas and stools, and in cases of high intestinal obstruction, it may also involve nausea and vomiting. How long fasting should be continued in the case of intestinal obstruction depends on whether the patient has resumed passing gas and stools, as well as whether symptoms such as abdominal pain, bloating, nausea, and vomiting have subsided. If the patient's abdominal pain and bloating have mostly subsided, passing gas and stools have resumed, and there is no bloody stool or symptoms of nausea and vomiting, then a gradual reintroduction of a liquid diet can be started. If abdominal pain and bloating do not worsen, and there is passing gas and stools, then a transition to a semi-liquid diet until a normal diet is resumed can be made. Therefore, the duration of fasting for intestinal obstruction should be determined based on the effectiveness of the treatment for the obstruction.
