describe luminal,mural and extramural intestinal obstruction
Luminal intestinal obstruction refers to a condition where there is a blockage or narrowing of the intestinal lumen, the central hollow portion of the intestines. This can be caused by various factors such as the presence of a tumor, foreign object, or a twisted bowel. Luminal obstruction can cause symptoms like abdominal pain, distension, vomiting, and difficulty passing stool.
Mural intestinal obstruction occurs when there is a blockage or narrowing of the intestinal wall. This can happen due to conditions like inflammation, scarring, or thickening of the intestinal wall. Mural obstruction can be caused by conditions such as Crohn's disease, diverticulitis, or tumors. The symptoms of mural intestinal obstruction are similar to luminal obstruction and may include abdominal pain, bloating, nausea, and constipation.
Extramural intestinal obstruction refers to a condition where there is a blockage or compression of the intestines from outside the intestinal wall. This can be caused by factors such as hernias, adhesions, or tumors in nearby organs. The symptoms of extramural intestinal obstruction are similar to luminal and mural obstruction and include abdominal pain, distension, vomiting, and difficulty passing stool. Treatment for all types of intestinal obstruction may involve surgical intervention to remove the obstruction and restore normal intestinal function.
