Clinical manifestations obstruction

Intestinal obstruction is the main clinical manifestations of abdominal pain, vomiting, abdominal distension, No stool and no anal exhaust. The emergence of these symptoms occur and obstruction of , parts of height, and closely related to the degree of intestinal blockage.
(1) abdominal pain: simple mechanical intestinal obstruction is generally paroxysmal keen colic, intestinal obstruction above the site due to strong peristaltic. Such pain can have the following characteristics: ① wave-by weight, and then reduce, after a period of quiet again attack. ② abdominal pain attack may flu gas fell to a sudden stop at the site, at this time the most intense abdominal pain, and then there temporarily alleviate. ③ when there will be the onset of abdominal pain or intestinal peristalsis, the patient consciously seems to be mass movement. ④ abdominal pain can be heard Music hyperthyroidism, sometimes patients themselves can be heard.
Strangulating intestinal obstruction due to the mesenteric ischemia and inlay closed, abdominal pain often associated with persistent abdominal pain paroxysmal heavier than intense pain. Sometimes mesenteric serious strangulating, can cause persistent severe abdominal pain, abdominal pain, in addition to other signs are not obvious, the diagnosis can cause difficulties.
Paralytic ileus abdominal pain are often not obvious, paroxysmal colic is particularly rare. Obstruction unless there is strangulating, abdominal pain significantly better when small intestinal obstruction, usually pain.
(B) vomiting: vomiting in the obstruction can occur soon after, as in the early days of reflection, for food or vomit gastric juice. Then he entered a period of quiescent, recurrent vomiting time positions may be as obstruction, such as high as small bowel obstruction, quiescent short, more frequent vomiting, gastric juice for vomit, duodenal fluid and bile. As low as small bowel obstruction, quiescent period can be maintained 1 to 2 days before re-vomiting, with the smell of vomit samples of the feces. As for the strangulating obstruction, vomit can be a SEPIA or bloody. When vomiting colonic obstruction rare.
(C) abdominal distension: abdominal distension general obstruction occurred in a period of time after beginning to emerge. Abdominal distention extent of the site and obstruction, high abdominal distension of small bowel obstruction, not obvious, while low performance for the whole of obstruction of abdominal swelling, accompanied intestinal type. When all paralytic ileus significant abdominal swelling, but not with intestinal type. Closed loop can be a partial obstruction of expansion, drum sound. Obstruction by ileocecal valve can be closed showed that abdominal swelling and often a high degree of asymmetry.
(4) Exhaust stop defecation: Complete obstruction after defecation exhaust stop. As peristalsis in the early increase in the residual obstructive following sites can emit gases and stool, a small amount of exhaust so early defecation can not rule out the diagnosis of intestinal obstruction. In some strangulating intestinal obstruction such as intussusception, mesenteric vascular thrombosis or embolism, since bloody anal discharge liquid or jam-like it.
