Severe abdominal infection

Introduction Severe abdominal infection is a more complicated problem in abdominal surgery. Severe abdominal infection refers to a wide range of infections of the abdominal cavity, which lasts for a long time, and is associated with peritoneal infection of multiple organ dysfunction syndrome (MODS).

Cause

The cause of severe abdominal infection

Common causes of severe abdominal infections in abdominal surgery include multiple abdominal trauma, severe pancreatitis, abdominal abscess, and postoperative stomach, intestine, gallbladder, pancreas, and external hemorrhoids.

The diagnostic methods for identifying the location and form of abdominal infection are mainly ultrasound and CT. B-ultrasound is often affected by abdominal gas accumulation in the treatment of abdominal infection, but can guide the puncture drainage of abscess. CT can understand the location of the infected lesion, the related changes of the adjacent organs, and even the inflammation and edema of the intestinal wall, the effusion of the upper and lower jaws, and the accumulation of gas can be clear.

Differential diagnosis

Severe abdominal infection is confusing

1. Underarm infection: The underarm abscess is a secondary infection, and its location is related to the primary disease. The localized empyema located below the diaphragm, in the transverse colon and above the mesentery is collectively referred to as the subphrenic abscess. The right posterior interhepatic abscess is the most common, and the cause is related to the influence of lymphatic flow and respiratory movement. The intra-abdominal pressure in this space of the abdominal cavity is the lowest. Followed by the right subhepatic space and the right upper anterior space abscess, the left axillary abscess is relatively rare.

2, appendix infection: Iris, Vermiform Appendix, is a degenerative organ of humans (the herbivore's appendix is very developed), about 7-9 cm long, about 0.5 cm in diameter, located in the lower right side of the abdomen, inside the cecum, proximal end It is connected with the cecum and the distal end is blocked. Because the appendix cavity is small, it is a blind tube. Food debris and fecal stones are easy to fall into the cavity, blocking the lumen and causing inflammation. The surface projection is called MacBurney point, and the position is right. Before the anterior superior iliac spine to the umbilical cord, at the middle 1/3 junction, there is tenderness at the point of appendicitis. The appendix in adults is mainly related to immune function. Soon after birth, lymphoid tissue begins to accumulate in the appendix. It peaks around 20 years old, then falls rapidly, and disappears after 60 years old. However, at the stage of physical development, the appendix can play the role of lymphoid organs, promote the maturation of B lymphocytes (a white blood cell) and immunoglobulin A. The generation of antibodies. The researchers also demonstrated that the molecules involved in the production of the appendix help lymphocytes to metastasize to other parts of the body. Most of the appendix infections occur after surgery.
