Abdomen & Gastrointestinal System RTEC 91 Pathology

Trachea anterior to esophagus

Normal KUB

Contrast Agents

Normal Stomach which position?

Normal Esophagus which position?

Congenital Disorders

Increased incidences with Down Syndrome 30% with esophageal atresia/tracheoeso- phageal fistula are born prematurely

“double bubble sign” indicates duodenal atresia

Cecum atresia

Hirschsprung’s Disease

Mega colon

Bowel Obstruction?

Pyloric Stenosis “String Sign”

Schatzki’s ring

Achalasia

Esophageal Strictures Most common etiology; peptic stricture Gastric contents/ acid contents reflux into the esophagus causing inflammation, scarring and stricture formation.

Peptic Ulcer Lower esophagus Stomach Duodenum

Esophageal Varices

Normal gastric pattern

Malabsorption Syndrome Group of diseases that interfere with normal digestion and absorption of food through the small intestine –Celiac disease –Regional Enteritis (Crohn’s Disease) –Ulcerative colitis

Celiac disease or Sprue

Regional Enteritis

Crohn’s Disease

ulcerative colitis

ulcerative colitis vs Crohn’s?

What is the most common abdominal emergency surgery in the U.S?

Appendicitis

Degenerative Diseases Gastrointestinal System

anterior abdominal hernia

Inguinal Hernia

Haital Hernia

Intrathoracic stomach malrotation

Bowel Obstructions Normally the small & large bowels are nearly always active in peristalsis. Various types of conditions can interfere with this action and cause obstruction. Mechanical vs Paralytic ileus

Bowel Obstruction “Step Ladder Sign”

Cantor tube Mechanical bowel obstruction

Gallstone Ileus

Volvulus

intussusception

paralytic ileus “step ladder sign”

Diverticular Diseases Diverticulum – pouch or sac of the mucous membrane. Esophagus, Colon, Bladder

Esophageal Diverticula

Zenker’s Diverticulum

Meckel’s Diverticulum

Diverticulosis

Diverticulitis

Neoplastic Diseases Benign or Malignant Esophagus, Stomach, Small-Bowel, Colon Endoscope, Colonoscopy, Sygmoidoscopy is best to diagnose

Leiomyoma

Malignant vs Benign Tumors

Gastric neoplasm w/ perforation

Small bowel tumor

Colonic Polyps

Sigmoid colon CA

Colon mass

Cecum mass

Colon CA – “apple core sign” What else do you see?

Free air

Calcified fibroid

Calcified aorta
