GI MOTILITY DISORDERS PART 2 Small Intestinal Motility

Objectives – Small Intestinal Motility

Enteric Nervous System in the Small Bowel has “APPS” for five kinds of motor behavior

An Abnormal Power Propulsion is running pathologic states with cramping abdominal pain fecal urgency and acute watery diarrhea

An Orally Directed Power Propulsion APP is running during emesis

Obstructive Ileus and Paralytic Ileus Causes Narrowed lumen Closed lumen Characteristics Strong propulsive circular muscle contractions Symptoms Severe abdominal pain Abdominal distention Obstructive Ileus Causes Sequelae labarotomy (postoperative ileus) Peritonitis Metabolic dysregulation (diabetic ketoacidosis) Characteristics Propulsive circular muscle contractions diminished or absent Symptoms Severe abdominal pain Abdominal distention Paralytic Ileus Wood 2156 are forms of Pathologic Ileus
