How is kidney stone surgery performed?
How is kidney stone surgery performed? For kidney stone surgery, if the indications for surgical treatment are met, it is generally carried out in the following ways: The traditional method is open stone removal, which involves large traumas and high risks, adversely affecting the patient's postoperative recovery. Nowadays, there are some minimally invasive techniques, such as crushing the stones with a laser and then removing the stones through a corresponding tube, or directly removing the stones using a corresponding soft-endoscope. Therefore, the choice of surgery for kidney stones is generally based on related examinations to select an appropriate treatment method to alleviate the patient's condition.
Does an umbilical hernia hurt?
Umbilical hernias can be painful because they may become incarcerated or even rupture. An umbilical hernia occurs when the area has not completely closed, allowing abdominal organs, such as the omentum or intestines, to enter the hernia sac. If incarceration persists for an extended period, it can cause localized pain and even symptoms of nausea and vomiting. For umbilical hernias, we generally advocate conservative treatment within the first six months, as most patients can heal on their own. If the diameter of the umbilical ring is still greater than 1.5 cm after the age of two, we recommend surgical treatment. The conservative treatment for umbilical hernia involves using a coin or a flat board, larger than the umbilical ring, wrapped and pressed against the ring, and then secured with wide adhesive tape. This method can prevent the hernia from protruding and promote healing.
How to diagnose intestinal obstruction?
How to diagnose intestinal obstruction, which is a common acute abdomen condition in surgery. If symptoms such as cessation of passing gas or stools, abdominal pain, and vomiting occur, it may suggest the presence of an intestinal obstruction. The simplest diagnostic method for intestinal obstruction is to perform an upright abdominal plain film to assess the degree of obstruction, based on the presence or absence of fluid levels. Furthermore, identifying the fundamental cause of the obstruction is essential; this can be achieved through enhanced abdominal CT and colonoscopy to make a determination. An abdominal ultrasound can also be performed, which provides a better understanding of the condition of the intestinal obstruction. Using abdominal ultrasound, the presence of effusion can be detected, and by aspirating the effusion, its properties can be analyzed to determine if there is a condition such as bowel necrosis.
Do lipomas need surgery?
Lipomas do not necessarily require surgical treatment. They can occur in various parts of the body and are usually characterized by good mobility, a complete capsule, no tenderness, a firm texture, and mostly clear boundaries. They often present no clinical symptoms and are found incidentally. Diagnosis can be confirmed through ultrasonography. In most cases, patients only need follow-up observation. However, for lipomas in special locations, if they affect appearance or grow rapidly causing symptoms, surgical treatment may be considered. After a complete excision, pathological examination is necessary because a very small number of cases may turn out to be liposarcomas, which might require further treatment.
Does adenoid hypertrophy always require surgery?
Is surgery necessary for adenoid hypertrophy? The answer is not necessarily. Adenoid hypertrophy is generally caused by acute rhinitis, tonsillitis, or acute epidemic influenza, among other factors. These factors can lead to the rapid proliferation and enlargement of the adenoids, which may compress the tissues of the nasal cavity, causing nasal obstruction or sinusitis. In such cases, it depends on the symptoms triggered and how significant the impact is on the patient. If the symptoms are not particularly severe, some non-surgical treatments can be adopted, such as enhancing the body's own disease resistance. Oral medications for clearing heat and detoxifying, and if necessary, traditional Chinese medicine for promoting blood circulation and removing blood stasis can be used to adjust the condition. If the enlargement of the adenoids is significantly alleviated with these medicinal treatments, surgery may not be necessary. However, if the disease is not well-controlled and severely affects breathing or swallowing, surgical treatment may be considered.
How to relieve intestinal obstruction
How to alleviate intestinal obstruction, which means how to treat intestinal obstruction. After the occurrence of intestinal obstruction, it is first important to clarify what intestinal obstruction is. Intestinal obstruction is characterized by cessation of gas and stool passage from the anus, and is usually accompanied by symptoms such as abdominal distension, nausea, vomiting, and even fever. If intestinal obstruction occurs, firstly, do not eat or drink, and then carry out appropriate examinations to identify the cause of the obstruction. If it is adhesive obstruction, treatment generally includes fasting, gastrointestinal decompression, anti-inflammatory treatment, fluid replenishment, and enemas as symptomatic treatment measures, trying to keep the treatment as conservative as possible. If the obstruction is caused by a tumor, it is preferable to perform surgery to remove the obstruction based on a clear diagnosis, as this is the only effective treatment.
Principles of Intestinal Obstruction Treatment
In the treatment principles of intestinal obstruction, the basic treatment methods apply to both partial and complete intestinal obstructions. Firstly, gastrointestinal decompression is required based on the situation. Gastrointestinal decompression involves the insertion of a gastric tube, which is determined by whether the patient has symptoms of nausea and vomiting. If these symptoms are prominent, a gastric tube should be placed to drain the stomach contents, thus alleviating the burden and swelling of the intestines and aiding in the treatment of the disease. Another aspect is fluid replenishment and anti-inflammation, as intestinal obstruction will definitely lead to changes in intestinal flora and concurrent infections, making anti-infection measures very important. Fluid replenishment involves administering nutrient solutions to provide nutrition and prevent electrolyte imbalances. Additionally, enemas or traditional Chinese medicine may be used to facilitate intestinal motility. During this treatment process, it is crucial to closely monitor the condition to assess if exploratory surgery is indicated. As the condition can either improve or worsen, close observation is extremely important.
Intestinal Obstruction Nursing Measures
Intestinal obstruction is primarily a disease that requires treatment, which involves fasting from water, gastrointestinal decompression, anti-inflammation treatments, enemas, and sometimes the auxiliary use of traditional Chinese medicine. The nursing measures for this condition build upon these treatments and involve further management of daily activities. Generally, patients with intestinal obstruction must be cautious with their diet to avoid overeating or consuming foods that are hard to digest or that could potentially form obstructions. Secondly, it is important to manage and ensure that patients avoid vigorous exercise, as such activity can lead to the recurrence of intestinal obstruction, especially if there are adhesions within the abdominal cavity.
Can you run with an umbilical hernia?
Patients with umbilical hernias are generally advised against engaging in vigorous activities such as running and jumping. This is because an umbilical hernia is a type of hernia that can lead to incarceration or even rupture due to sudden increases in abdominal pressure, which would require emergency surgery. For umbilical hernias, conservative treatment is mostly adopted. Typically, affected children can self-heal within six months through conservative treatment. However, if the condition persists beyond the age of two and the diameter of the umbilical ring is still greater than 1.5 cm, surgical treatment is recommended. If the patient is over the age of five, it is advised to undergo surgery as soon as possible, regardless of the circumstances. Both before and after the surgery for an umbilical hernia, vigorous activities are not recommended. Intense activities increase abdominal pressure, which on one hand can lead to complications like incarceration, and on the other hand, can affect the outcome of the surgical treatment.
What foods are good for acute gastroenteritis?
For patients with acute gastroenteritis, it is mainly important to prevent very strong irritation to the entire mucosa of the digestive tract, otherwise symptoms such as abdominal pain and diarrhea may occur. For patients with acute gastroenteritis, in terms of diet, it is mainly important not to consume spicy and stimulating foods, to eat easily digestible foods as much as possible, and not to eat too much coarse dietary fiber, as this may be beneficial for alleviating the disease.
