What is chronic gastritis?
Gastritis is divided into acute and chronic types. Chronic gastritis is primarily caused by various reasons that lead to chronic inflammation of the gastric mucosa or atrophic changes. This condition is quite common in clinical practice. Generally, about 85% of patients undergoing gastroscopy exhibit such symptoms, and with increasing age, the incidence of atrophic diseases gradually increases. The symptoms mainly manifest as abdominal pain, predominantly in the upper abdomen, bloating, belching, and even symptoms of black stools, which, if present, indicate bleeding of the gastric mucosa.
Is cervical polyp surgery painful?
Is cervical polyp surgery painful? The answer is not certain, as many minimally invasive techniques are now used, and some very effective anesthetics are applied, so the pain from cervical polyp surgery is not significant. When conducting hysteroscopic surgery or gynecological color ultrasound, if cervical polyps are found, they are generally removed through minimally invasive methods using a hysteroscope. The main purpose of this is to make a definitive pathological diagnosis of the polyp, which can help in early screening for many cervical diseases, such as cervical cancer.
How big must a liver hemangioma be to require surgery?
Regarding whether a liver hemangioma requires surgery, size is only one factor that determines the necessity of surgery. Generally, hemangiomas larger than five centimeters have reached the criterion for surgical intervention. However, while the size of the hemangioma is one aspect, we must also consider its location and whether there are any symptoms of compression, as well as the potential for further pathological changes. Therefore, the necessity for surgery is influenced by size, but it is just one of the factors. Of course, the larger the hemangioma, the higher the possibility of requiring surgery.
What is lipoma surgery?
The necessity of surgery for lipomas depends on their location. Lipomas are commonly found on the limbs. Whether surgery is needed depends on the size, location, and impact of the lipoma on the body. Surgery is generally recommended for lipomas that are particularly large or symptomatic. The surgical procedure involves excision followed by a pathological examination, as there is still a possibility that some lipomas could be liposarcomas, especially when located on the limbs, where such cases are more common. Therefore, for lipomas with significant symptoms and prominent manifestation, surgical removal is usually advised.
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.
Will an umbilical hernia cause abdominal pain?
Umbilical hernia may cause stomach pain. This is possible because an umbilical hernia occurs when the intestines push through a weak spot in the belly button area due to pressure. In most cases, it is the small intestine that protrudes through the hernia. If a large portion of the small intestine protrudes, it can lead to kinking and potentially cause an obstruction of the small intestine. Once the small intestine is obstructed, it can lead to abdominal pain, and may also be accompanied by bloating, nausea, and vomiting. Thus, in cases where the small intestine is kinked, it is possible for an umbilical hernia to cause stomach pain.
How to treat chronic non-atrophic gastritis with bile reflux?
For cases of chronic non-atrophic gastritis with bile reflux, it is first necessary to clarify whether there is a Helicobacter pylori infection, which can be determined by a breath test. Based on this, regular visits to the department of gastroenterology for diagnostics and treatment can be established. Firstly, it is important to take oral medication to protect the gastric mucosa and then to promote gastrointestinal motility. Regular follow-ups are very important. Generally, for patients with non-atrophic gastritis and bile reflux, it depends on whether the condition is high or low. For those in the high category, it is necessary to undergo a gastroscopy every six months.
How long will it take for an umbilical hernia to heal?
Umbilical hernia can heal on its own, generally, if the appropriate treatment method is chosen, most umbilical hernias can heal within six months. For children over two years old, if the umbilical hernia has not healed and the diameter of the umbilical ring exceeds 1.5 cm, active surgical treatment is also chosen. For children over five years old, surgical treatment is recommended regardless of the situation. Umbilical hernia occurs because the umbilical ring does not close in time during the child's development, causing the abdomen to protrude. The common treatment method is to choose a coin or cardboard larger than the umbilical ring, wrap it up, press against the umbilical ring, and fix it with adhesive tape to prevent it from moving. This treatment method generally works well and can avoid surgery. However, during the observation process, it is necessary to avoid the occurrence of incarceration or rupture of the hernia.
Do lipomas infect other people?
Lipomas are non-contagious and are tumorous formations of normal fatty tissue, often found in the limbs and trunk. They generally have clear boundaries, are soft in texture, and may feel cystic without causing pain. Lipomas grow slowly and can sometimes become very large. For most lipomas, observation is sufficient, and diagnosis can be confirmed through ultrasonography. Most patients do not require surgical treatment. However, if there is suspicion of malignancy in deeper lipomas, timely surgical removal is necessary. For lipomas that grow rapidly, cause symptoms, or affect appearance, early surgical intervention is also recommended. If pathology confirms the diagnosis, some lipomas may be liposarcomas. Most can be assessed for risk, and further treatment might be needed.
The difference between umbilical hernia and umbilical protrusion
Umbilical hernia refers to a condition in children where the umbilical ring does not close during development, causing a defect in the abdominal wall. This situation can be treated conservatively. Within half a year, the effects are generally good. You can choose a coin larger than the umbilical ring or cover it with a flat board, press it against the umbilical ring, and then use adhesive tape to fix it to prevent movement. Generally, most patients can heal on their own. If the diameter of the umbilical ring still exceeds 1.5 cm after two years old, it is advisable to actively accept surgical treatment. Moreover, the protrusion may not involve a defect in the abdominal wall but a potential weakness in the abdominal wall at the navel. Under conditions of increased abdominal pressure, there can be a protruding appearance at the navel. The biggest difference from an umbilical hernia might be that the umbilical protrusion might present a lump that does not completely disappear. In the case of an umbilical hernia, if the contents can be returned to the abdominal cavity, the hernia can disappear completely.
