Spontaneous rupture of the rectus abdominis

Introduction to spontaneous rupture of the rectus abdominis Spontaneous rupture of the rectus abdominis (spontaneous rupture of musculus rectus abdominis) refers to the rupture of the rectus abdominis caused by indirect trauma, which is associated with the rectus abdominis fibrosis, often occurs when the abdominal pressure is increased, suturing the abdominal muscles is the main treatment. basic knowledge The proportion of the disease: the incidence rate is about 0.001% -0.002%, more common in obese patients Susceptible people: no special people Mode of infection: non-infectious Complications: bloating

Cause of spontaneous rupture of the rectus abdominis

Rectus abdominis lesions (28%):

Muscle fiber weakness caused by various reasons, such as multiple pregnancy, chronic long-term cough, difficulty in defecation, vomiting or sneezing, so that muscle fibers are repeatedly damaged, degenerated, muscle fiber elasticity is reduced, intra-abdominal pressure is increased or repeated intra-abdominal The pressure suddenly increases, causing rupture when it exceeds the tensile strength of the rectus abdominis.

Increased intra-abdominal pressure (30%):

Increased intra-abdominal pressure caused by various reasons, such as pregnancy, long labor, etc. can lead to excessive stretching of the rectus abdominis, fatigue and anti-tension decline, over time, it is easy to cause rupture and bleeding of the rectus abdominis, so it is extremely difficult The intraductal hematoma of the rectus abdominis is different, or both.

Cool and tired (15%):

Others suggest that cold and fatigue may induce spontaneous rupture of the rectus abdominis.

Prevention of spontaneous rupture of rectus abdominis

Pay attention to prevent upper respiratory tract infection, avoid constipation and difficulty urinating, and prevent recurrence of the disease.

Spontaneous rupture complications of the rectus abdominis Complications

Spontaneous rupture of the rectus muscle can cause local blood pressure to force the rectum, bladder, ureter, compression of the rectum can cause difficulty in defecation, compression of the bladder can form frequent urination, urgency, compression of the ureter can cause decreased urine output, serious cases can be due to the capsule Increased internal pressure affects glomerular filtration rate resulting in a significant reduction in urine output

Symptoms of spontaneous rupture of the rectus abdominis. Common symptoms The rectus abdominis touches the border... Constipation Abdominal muscles are tight and the lower abdomen is severely painful and gradually... Nausea

Before the onset, often accompanied by a history of upper respiratory tract infection, history of bronchitis or constipation, sudden onset, severe pain in the lower abdomen, uneasiness, gradually spread to the midline of the abdomen, but no radiation pain, sometimes accompanied by nausea, occasional vomiting, large, urinating Normal, the muscles of the lower abdomen are muscle tension, and the fixed mass of the border is unclear in the rectus abdominis.

Examination of spontaneous rupture of the rectus abdominis

Routine tests showed normal clotting time and a slight decrease in red blood cell count.

1. B-ultrasound and CT examination revealed that the mass was located in the sheath of the rectus abdominis, which was not connected to the abdominal cavity. The density of the hematoma was lower and the boundary was clearer.

2. X-ray examination of abdominal plain film and pyelography without positive findings.

Diagnosis and diagnosis of spontaneous rupture of rectus abdominis

1. A detailed history of trauma, history of pregnancy, history of infection and pathogenesis can help to make judgments.

2. Clinical features The lower abdomen is severely painful and gradually spread to the midline of the abdomen. The lower abdominal muscles are tight and the fixed mass of the border is unclear.
