Dynamic IO Adynamic IO |

|
Classification of intestinal obstruction |
1.Acc to onset: acute (SI) Chronic (LI) Acute on top of chronic 2. Site : -Lumen(FB, fecal impaction, gallstone) -on the wall: strictures, cancer. - pressure from outside: hernia, volvulus, adhesion, interssusception. 3. Causes of obstruction mechanical obstruction Strangulation obstruction Functional obstruction. (paralytic ileus, MVO)

Pathophysiology of intestinal obstruction |
1.At proximal to obstruction: - hyperperistalsis - anti peristalsis phase (vomiting of content) - distension of loop due to fluid and gas. - increase the pressure against the wall-- occlusion of venous-- oedema - - more pressure-- occlusion of arterioles -- ischemia & gangrene. - bacterial overgrowth 2. At distal to obstruction - normal peristalsis and emptying of the content. - eventually become empty and collapse. Function obstruction: - no peristalsis (absent of bowel sound) |

Complication of intestinal obstruction |
Fluid & electrolyte loss Hypovolemic shock Toxemic Perforation & peritonitis |
|
|
Clinical picture of IO |
Pain (colicky) Vomiting Distention Constipation |
|
|
Treatment of IO |
1. Resuscitation (pre operative preparation) = drip and suck (Ryle tube), IV fluid, antibiotics. 2. Operation. - Deliver the ceacum & examine. - decompress the bowel - deal with the cause. |
