Spontaneous rupture of the rectus abdominis muscle

　　History of upper respiratory tract infection, tracheitis, constipation patients, especially for elderly constipation with little drinking water, due to the weakened peristalsis function of the intestines, forceful defecation can cause a significant increase in intra-abdominal pressure and trigger the disease. It often occurs suddenly with severe lower abdominal pain, restlessness, and gradual spread to the midline of the abdomen, but without radiation pain. Sometimes accompanied by nausea, occasionally vomiting, normal bowel movements and urination. Physical examination shows muscle tension in the lower abdomen, and an indistinct, fixed mass can be palpated in the rectus abdominis area.

　　The spontaneous rupture of the rectus abdominis muscle can cause local hypertension, compressing the rectum, bladder, and ureter. Compression of the rectum can lead to difficulties in defecation, compression of the bladder can cause frequent urination and urgency, compression of the ureter can lead to decreased urine output. In severe cases, increased intravesical pressure can affect the glomerular filtration rate, resulting in significant reduction in urine output, increased creatinine and urea nitrogen levels, and even trigger renal insufficiency and failure.

　　Before onset, there is often a history of upper respiratory tract infection, tracheitis, or constipation with effort, and the onset is sudden, with severe lower abdominal pain, restlessness, and gradually spreading to the midline of the abdomen, but without radiation pain. Sometimes accompanied by nausea, occasional vomiting, normal defecation, and urination. Physical examination shows muscle tension in the lower abdomen, and an unclear boundary mass can be felt in the rectus abdominis area.

　　Spontaneous rupture of the rectus abdominis muscle refers to the rupture of the rectus abdominis muscle caused by non-direct trauma. The cause is usually accompanied by a history of upper respiratory tract infection, tracheitis, or constipation with effort, which causes an increase in intra-abdominal pressure and induces spontaneous rupture of the rectus abdominis muscle. Therefore, reducing the increase in abdominal pressure can effectively prevent the onset of the disease. For elderly patients with constipation, it is recommended to increase the intake of fruits and vegetables, and drinking honey and yogurt can have a good effect on promoting intestinal peristalsis, which can effectively prevent the onset of the disease due to increased abdominal pressure caused by intestinal problems.

　　Routine blood tests showed normal coagulation time and slightly decreased red blood cell count.

　　1. Ultrasound and CT examination:It can be found that the mass is located within the rectus sheath and does not communicate with the peritoneal cavity, and the density is lower when complicated with hematoma, with clear boundaries.

　　2. X-ray examination:Abdominal X-ray and renal pelvis contrast examination showed no positive findings.

　　Prepare dishes mainly with vegetables and lean meat, eat some kelp and seaweed, high-protein, high-nutrition diet, such as beef, milkfish, chicken, and high-nutrition food.

　　For patients with slight bleeding, clinical observation, bed rest, and the appropriate use of hemostatic drugs can prevent the exacerbation of bleeding. For patients with large amounts of bleeding, it can form a mass that compresses the rectum, bladder, and ureter, and can be surgically removed. For patients with particularly large amounts of bleeding, blood pressure and hemoglobin concentration should be monitored during surgical treatment, and blood transfusion support treatment should be determined based on the monitoring situation.
