Crohn's disease is what kind of disease?
Crohn's disease is an inflammatory bowel disease primarily affecting the terminal ileum and the right half of the colon. Typical symptoms include abdominal pain, diarrhea, intestinal obstruction, and it may also lead to complications such as intestinal perforation or rectal bleeding. Additionally, it can affect joints, skin, liver, and other organs. The course of the disease is often recurrent and difficult to cure completely. Currently, there are no specifically effective drugs. Severe complications may require surgical treatment. Mild symptoms can be controlled with medication. Dietary guidelines suggest eating small, frequent meals that are high in nutrition and low in fat, and it is important to consume more vegetables and supplement with vitamin C.
How is appendicitis surgery done?
Appendicitis currently primarily involves two surgical methods. One is appendectomy via laparoscopy, and the other is the traditional method involving an incision at McBurney's point to remove the appendix. While the surgical methods differ, the principle behind the surgery is the same: in the abdominal cavity, the appendix is separated from the mesentery, then the appendiceal artery is ligated and the appendix is removed from the base. The stump is disinfected with iodine, and purse-string sutures are used to wrap the stump. If there is an appendiceal perforation causing diffuse peritonitis, it is necessary to thoroughly clean the pus from the abdominal cavity, then check that no surgical instruments are left inside before closing the abdomen. Postoperatively, the use of antibiotic medication depends on the patient's condition, and a minimum rest period of two weeks is required. (The use of medications should be under the guidance of a doctor.)
How to diagnose appendicitis
Appendicitis is primarily diagnosed clinically through a physical examination. The patient is asked to lie flat, exposing the abdomen, with legs bent. The doctor stands on the patient’s right side and uses the right hand with fingers together to gently rub the abdomen, pressing on the McBurney's point. If there is significant pain, this is considered positive tenderness. Then, the doctor quickly lifts the fingers; if there is significant rebound pain, it is generally confirmed as acute appendicitis. During acute appendicitis, as the appendix lumen expands and the appendix becomes congested and edematous, ultrasound imaging can also show corresponding signs that serve as an auxiliary diagnosis. Once acute appendicitis is confirmed, it is mostly treated surgically.
How to care for gastric ulcer bleeding
Gastric ulcer bleeding is a relatively common complication. First, it is important to soothe the patient's emotions, encourage rest, reduce mental stress, and pay attention to significant bleeding, which can cause vomiting of blood. It is necessary to promptly clean the blood stains in the mouth to prevent aspiration, provide timely symptomatic treatment, and choose to use proton pump inhibitors combined with endoscopic hemostasis. Vascular intervention or surgery may be required when necessary. Dietary management should be strengthened, with regular meals, consumption of soft, easily digestible food, and avoidance of hard, cold foods. It is crucial to strictly abstain from smoking and alcohol, and to consume less strong tea, coffee, etc., while actively treating any complications. (Please use medications under the guidance of a doctor.)
How to relieve pain from acute appendicitis
For rapid pain relief in acute appendicitis, one can choose antispasmodic or sedative medications. However, it is important to note that acute appendicitis often requires surgical treatment clinically. If the pain is not particularly severe, conservative medication treatment can also be chosen, using sensitive antibiotics for anti-inflammatory pain relief. If surgery involves appendectomy, laparoscopic appendectomy is generally chosen, which has less intraoperative bleeding and quicker postoperative recovery. Only after the appendix is removed can the onset of acute appendicitis be effectively controlled or the transition from acute to chronic appendicitis prevented. (Specific medications should be used under the guidance of a physician.)
Can appendicitis recur?
Acute appendicitis, if not treated surgically, can relapse under poor lifestyle and dietary habits and then transform into chronic appendicitis. Therefore, appendicitis can recur. However, if the appendix is removed during an acute episode of appendicitis, then appendicitis will not recur. Currently, the primary clinical treatment for appendicitis is surgery, because without surgery, the recurrence rate of appendicitis is quite high, and ultimately, the appendix must be removed.
Can appendicitis cause a fever?
Appendicitis can cause fever. After the fever, a routine blood test will show a significant increase in white blood cells, which is often referred to as an elevated blood profile. In addition to fever, appendicitis may also cause vomiting and nausea. A typical symptom is abdominal pain, starting around the navel and then gradually moving to the lower right abdomen. For the fever, active symptomatic fever reduction should be pursued, or appendectomy can be chosen. Currently, laparoscopic appendectomy is more common, with less bleeding during the operation and faster post-operative recovery.
Does appendicitis cause fever?
Appendicitis often causes fever, due to systemic infection caused by inflammation entering the bloodstream. Generally, it only causes a low fever without chills. The temperature in suppurative appendicitis does not exceed 38 degrees Celsius. High fever above 38 degrees Celsius is mostly seen in cases of appendiceal perforation or concurrent peritonitis. In addition to fever, acute appendicitis also presents with abdominal pain, tenderness and rebound pain in the abdomen, tension in the abdominal muscles, as well as nausea, vomiting, and increased frequency of bowel movements due to reflexive gastric spasms.
How is acute appendicitis diagnosed?
The diagnosis of acute appendicitis is primarily based on clinical symptoms, signs, and auxiliary examinations. The patient describes abdominal pain accompanied by nausea and vomiting. During the physical examination, migratory pain in the lower right abdomen and significant rebound tenderness upon palpation are noted. Additionally, ultrasound diagnostics suggest swelling of the appendix lumen, all indicative of acute appendicitis. For acute appendicitis, once confirmed, surgery is generally required to remove the appendix, which is the only way to completely cure acute appendicitis.
Gastrointestinal cold with fever for a few days
Gastrointestinal colds are mostly caused by viral infections of the intestines leading to gastroenteritis and symptoms of upper respiratory infections. Typically, a fever may last two to three days, but this can vary from person to person. If the individual has a strong immune system, the duration of the fever may be shorter; however, in elderly people or infants, the duration may be extended. It is important to focus on active treatment, which includes drinking plenty of water, eating more vegetables, reducing time spent outdoors, actively using anti-cold medications and medications for treating intestinal infections. During this time, attention should be paid to maintaining a regular diet, with timely and measured meals, and reducing consumption of greasy, spicy, and irritating foods. (Specific medications should be used under the guidance of a physician.)
