Study Notes
Intestinal Disorders
- Appendicitis: Acute inflammation of the appendix, a worm-like tube attached to the cecum.
- Occurs when the appendix's opening to the cecum becomes blocked, allowing bacteria to accumulate and form an abscess.
- Common causes include fecaliths (hard fecal masses) in adults and lymphoid hyperplasia (enlarged lymphoid tissue) in children (often triggered by viral infections).
- Initial pain is typically in the mid-epigastric region around the umbilicus due to irritation of the visceral peritoneum (poorly localized autonomic innervation).
- As inflammation progresses, pain moves to the right lower quadrant (RLQ), specifically to McBurney's point (one-third of the distance from the iliac crest to the umbilicus).
- Diagnosis can be made by history and physical exam. CT scan if unsure or more details are needed.
- Treatment involves surgical removal of the appendix.
- Acute abdomen: acute onset abdominal pain with rebound tenderness (pain when pressure is released from the abdomen); a serious diagnosis needing urgent intervention due to potential for perforation and peritonitis.
Diverticular Disease
- Diverticulum: A blind pouch or sac protruding from the GI tract wall—a "false" diverticulum lacks all three GI tract layers.
- Commonly occurs in the sigmoid colon.
- Caused by straining to pass stool (increased intra-abdominal pressure) and a low-fiber diet. Resulting in hard stool.
- Diverticulosis: Presence of multiple diverticula.
- Diverticulitis: Inflammation of a diverticulum often presenting with left lower quadrant pain, rebound tenderness, and elevated white blood cell count. Potential for bleeding (hematochezia) or occult blood (detected with a fecal occult blood test).
- Complication possibilities include abscess formation, bowel obstruction, fistula formation (connection to another structure, e.g., colovesical fistula—air or fecal matter in urine), and perforation.
- Treatment can include antibiotics and sometimes surgery.
Adhesions
- Adhesions: Bands of scar tissue in the peritoneal cavity, often forming after abdominal surgery.
- Can cause small bowel obstruction, infertility, chronic abdominal/pelvic pain.
- Treatment is lysis of adhesions (surgical cutting of the adhesions), though this can sometimes result in more adhesions.
Intussusception
- Intussusception: Telescoping of one portion of the intestine into another, often triggered by a "lead point" (e.g., Meckel's diverticulum, lymphoid hyperplasia, viral gastroenteritis).
- Often happens near the ileocecal junction in children under one year old.
- Can lead to compromised blood supply, necrosis, bleeding, and presenting with "currant jelly" stool (thick, red stool).
- Medical emergency requiring treatment.
Intestinal Volvulus
- Intestinal volvulus: Twisting of the bowel around its mesentery.
- Common locations are the sigmoid colon and the cecum.
- Can lead to bowel obstruction and infarction.
- Imaging in sigmoid volvulus often show dilated sigmoid colon and an airless rectum.
- Typically occurs in elderly individuals (mean age ~70).
Bowel Obstruction
- Bowel obstruction: Often in small intestine (75%).
- Presents with abdominal pain, nausea, vomiting (vomiting of stomach contents due to obstruction), abdominal distension, and obstipation (inability to pass stool or gas).
- Common causes include adhesions, hernias, and tumors (colon).
- Diagnosis can include abdominal x-ray (dilated loops of bowel, air-fluid levels).
Hirschsprung's Disease
- Hirschsprung's disease: Congenital motor disorder of the intestine due to absence of ganglion cells in the bowel (neural crest cells do not migrate properly)
- Results in lack of peristalsis leading to bowel obstruction.
- Presents in newborns with failure to pass meconium, abdominal distension, and bilious vomiting. Rectum is always involved.
- Diagnosis often made via rectal suction biopsy to look for ganglion cells.
- Treatment involves surgical resection of affected portion.
- Rectum is always involved in diagnosis.
Ileus
- Ileus: Loss of bowel peristalsis.
- Common causes include medications (especially narcotics), post-operative states (post-op ileus), and Ogilvie syndrome.
- Ogilvie syndrome: Pseudo-obstruction (dilated colon without an obstructing lesion). Often seen in sedentary, hospitalized, elderly patients.
Irritable Bowel Syndrome (IBS)
- IBS: Functional bowel disorder (problem with bowel function, not structure).
- Characterized by recurrent abdominal pain, at least 3 days/month for 3 months.
- Associated with bowel changes—frequency, appearance—and defecation relieves pain.
- Primarily presents in women. No reliable cure available, treatment is often symptomatic.Â
Necrotizing Enterocolitis (NEC)
- NEC: Neonatal disorder (first month of life), commonly in preterm/low birth weight infants.
- Intestinal necrosis, obstruction, and possible perforation.
- Signs include abdominal distension, nausea, vomiting, and air in the bowel wall (pneumatosis intestinalis).
- Treatment involves bowel rest, antibiotics, and often surgery.
Angiodysplasia
- Angiodysplasia: Aberrant blood vessels in the GI tract, often in the cecum/right colon.
- Common cause of lower GI bleeding (hematochezia) in older adults.
- Thought to develop from high wall stress and compression over time.
Hereditary Hemorrhagic Telangiectasia (HHT)
- HHT (Osler-Weber-Rendu Syndrome): Inherited vascular disorder.
- Multiple dilated capillary beds (telangiectasia) throughout the GI tract (similar to angiodysplasia).
- Risk of GI bleeds, nosebleeds, and iron deficiency anemia.
- Often leads to formation of arterial vascular malformations (AVMs).
