Intra-abdominal adhesions are generally considered harmless if they do not interfere with the motility of the intestinal canal. Most adhesions do not constitute an obstacle to the patency of the intestinal canal in a void state, but when the contents of the intestinal canal increase and expand, adhesions tend to affect the patency of the intestinal canal.
The following are the possible mechanisms of intestinal obstruction caused by adhesions: 1. After eating, more chyme or contents accumulate in the proximal intestinal segment of the adhesion point, and the intestinal tube expands and its weight increases.
2, adhesion tissue or organs form a strip-like adhesion zone, the formation of crypt and cavity in the abdominal cavity, the expansion of the intestinal tube activity is limited by the region, in position change, more likely to occur internal hernia, the intestinal wall by external compression, resulting in obstruction. The adhesion zone directly compresses the dilated intestinal canal and causes obstruction of intestinal contents.
3. Adhesive tissues form membranous bands, which adhere the intestinal tube into a mass, restrain the mobility of the intestinal tube, prevent the coordinated peristaltic movement of the intestinal tube, and cause stagnation of intestinal contents. The above analysis shows that increased intestinal lumen contents and dilatation of the intestinal canal are the most common causative factors for intestinal obstruction in patients with postoperative intestinal adhesions. Therefore, patients with intestinal adhesions must pay attention to dietary control, eat less and more meals, choose an easily digestible diet with less residue, do not eat full meals, do not eat indigestible food, gas-producing food, and avoid the occurrence of diarrhea (fluid accumulation in the dilated small intestinal tube during diarrhea). Once the phenomenon of abdominal pain and bloating occurs after eating carelessly, we should reduce eating or fast temporarily and go to hospital or clinic for infusion treatment to keep the body water electrolytes constant.
