The rectus abdominis touches an ill-defined fixed mass

Introduction The spontaneous rupture of the rectus abdominis is often accompanied by a history of upper respiratory tract infection, a history of bronchitis or constipation. Sudden onset, severe pain in the lower abdomen, uneasiness, and gradually spread to the midline of the abdomen, but no radiation pain, sometimes accompanied by nausea, occasional vomiting, large, normal urine. Check the lower abdomen for muscle tension, and the fixed rectus in the rectus abdominis can be touched.

Before the onset, there is often a history of upper respiratory tract infection, history of bronchitis or exertion of constipation. Sudden onset, severe pain in the lower abdomen, uneasiness, and gradually spread to the midline of the abdomen, but no radiation pain, sometimes accompanied by nausea, occasional vomiting, large, normal urine. Check the lower abdomen for muscle tension, and the fixed rectus in the rectus abdominis can be touched.

1. Medical history: Detailed investigation of trauma history, pregnancy history, infection history and pathogenesis will help to make judgments.

2. Clinical features: severe pain in the lower abdomen and gradually spread to the midline of the abdomen. The lower abdominal muscles are tight and the fixed mass of the border is unclear.

Differential diagnosis

Identification

The outer wall of the abdominal wall has fixed tenderness: it is the main clinical sign of the semilunar hernia. The anterior and posterior layers of the rectus abdominis sheath heal at the lateral edge of the rectus abdominis, forming a semilunar, convex-laterally curved, sacral structure, ie the meniscus (Fig. 1, 2). The peritoneal or intra-abdominal organs protrude through the meniscus of the lateral abdominis, called the spigelian hernia, also known as the lateral abdomen. Spige (1617) first described the anatomy of the meniscus, so it is also known as spiglian.

Painful mass can be seen in the lower left abdomen: can be seen in ulcerative colitis, rectum, sigmoid cancer. Rectal, sigmoid schistosomiasis granuloma, left oocysts and so on.

There is tenderness in the cystic mass of the left upper abdomen: the cystic inflammatory mass in the left upper abdomen has obvious tenderness, such as the tumor in the middle of the abdomen, which is often a tumor or cyst of the stomach or pancreas, or an intragastric stone.

Upper abdomen mass: upper abdominal lesions caused by various reasons, palpation with mass. Common in liver cirrhosis, chronic pancreatitis, stomach cancer, gallbladder cancer and other diseases.
