Symptoms of intramural injury of large intestine?

summary

Most of the injuries were caused by industrial and agricultural injuries, traffic accidents, life accidents and fights, especially abdominal closed injuries. The incidence of abdominal visceral injury was the fifth, which was lower than that of small intestine, spleen, liver and kidney. Symptoms of intramural injury of large intestine? Let's talk about it.

Symptoms of intramural injury of large intestine?

(1) abdominal pain and vomiting: perforation or mass damage of colon and rectum, abdominal pain and vomiting after feces overflowing into abdominal cavity. The pain was first limited to the perforation, then spread to the whole abdomen and became diffuse peritonitis.

(2) peritoneal irritation: abdominal tenderness, muscle tension and rebound pain. The pain of perforation or rupture is the most obvious.

(3) bowel sounds were weakened or even disappeared.

matters needing attention

(1) colon external placement: it is suitable for multiple rupture of the free part of colon, such as transverse colon and sigmoid colon. After exploration, another incision was made to lift the injured intestinal loop out of the abdominal wall, and a small hole was poked under the mesenteric vascular arch. The glass tube was used as the supporting tube to fix the injured intestinal loop out of the abdominal wall to prevent it from retracting into the abdominal cavity. (2) suture of injured intestinal loop plus proximal external placement: suitable for ascending and descending colon and rectum to fix intestinal loop injury. During the operation, the peritoneum beside the wound must be cut, the injured intestinal loop must be dissociated, the wound must be debridement, and whether there are multiple perforations must be detected. After the wound is sutured in double layers at one stage, it must be put into the original position, and then the proximal colon must be dissociated for colostomy. For example, sigmoid colostomy was performed after rectal injury was sutured, and transverse colostomy was performed after descending colon injury was sutured. In order to achieve fecal flow diversion, promote wound healing.
