Stool-like discharge from abdominal wound

Introduction Abdominal incision or drainage of intestinal contents in the drainage opening is a reliable evidence of intestinal fistula, but it is difficult to accurately determine the location of the internal orifice. In general, the ileal effluent is mostly yellow rice porridge or thin paste, and the colonic sputum discharge is semi-formed or non-formed. Colonic hernia is a common surgical pathological condition. The abnormal passage between the gastrointestinal tract due to various reasons, the pathological path between the intestine and other hollow organs or between the intestine and the body surface belongs to the intestinal fistula. category.

Cause

Because of the different causes of intestinal fistula, the size and length of the fistula vary greatly. According to the shape of the intestinal fistula, the colonic fistula is roughly divided into three categories: 1 complete paralysis: due to surgery, the intestine is fully valgus, revealing the abdominal wall In addition, all or most of the contents of the intestines flow out of the mouth. 2 tubular fistula: can be pathological or postoperative, especially the abdominal drainage tube is hard, compression of the colon wall caused by necrosis of the colon, the tube is small and the tube is long, most of the intestinal contents flow into the intestine distal to the intestine Within the tube, only a small portion flows out of the mouth from the fistula. 3 lip-shaped sputum: mostly caused by trauma, the intestine is close to the abdominal wall, a part of the intestinal mucosa is turned out of the mouth, and the contents of the intestine are partially discharged from the external fistula and partially into the distal intestine. The mouth of the intestine wall may be single or multiple, and the outer mouth of the abdominal wall may also be single or multiple. Intestinal fistula caused by surgery or trauma, although it is a single sputum at the beginning, sometimes it is caused by the incision of the abdominal wall, the intestinal tract is exposed, the intestinal wall is infected, the edema is serious, the dressing is damaged or the intestinal cavity pressure forms multiple fistulas. Extrapyretic fistula is a low-grade hernia. The seriousness of the hazard is: on the one hand, abdominal infection, causing severe peritonitis, followed by loss of water and electrolytes and malnutrition.

Excretion of fecal samples from abdominal wounds is a definitive evidence for the diagnosis of intestinal fistula, and examinations have confirmed that abnormal passages in the colon and abdominal wall can also be diagnosed.

After colonic injury, inflammation or tumor, such as colonic repair or intestinal resection and anastomosis, anastomotic rupture and leakage occurred. It occurred 4 to 5 days after surgery. After the operation, abdominal pain was relieved, and persistent abdominal pain increased. With toxemia, such as elevated body temperature, abdominal tenderness, rebound tenderness and abdominal muscle tension are also getting worse, then you should first test the abdominal cavity infection, or the possibility of intestinal fistula. Intestinal content in the abdomen incision drainage is a reliable evidence of intestinal fistula, but it is difficult to accurately determine the location of the internal orifice. In general, the ileal effluent is mostly yellow rice porridge or thin paste, and the colonic sputum discharge is semi-formed or not formed, and the fecal auxiliary examination is performed.

Differential diagnosis

Identification:

It is mainly necessary to identify with other mouthwashes of the intestines.

diagnosis:

1. Excretion of fecal samples from abdominal wounds is the definitive evidence for the diagnosis of intestinal fistula. Examination of the abnormal passage of the colon and abdominal wall can also be diagnosed.

2, colonic injury, inflammation or tumors such as colonic repair or intestinal resection and anastomosis, anastomotic rupture and leakage occurred, occurred 4 to 5 days after surgery, began to have abdominal pain after surgery, and then continued abdominal pain increased Often accompanied by toxemia, such as elevated body temperature, abdominal tenderness, rebound tenderness and abdominal muscle tension are also getting worse, then you should first test the abdominal cavity infection, or the possibility of intestinal fistula. Abdominal incision In general, the ileal effluent is mostly yellow rice porridge or thin paste, and the colonic sputum discharge is semi-formed or non-formed.
