Study Notes
Ulcerative Colitis
- Hallmark sign of ulcerative colitis is bloody diarrhea
- Other symptoms include:
- Abdominal cramping
- Fecal urgency
- Tenesmus
- Extra-intestinal symptoms:
- Arthralgias
- Arthritis
- Iritis or uveitis
- Aphthous skin lesions
- Gallstones
- On physical exam:
- Check orthostatic blood pressure, pulse, and nutritional state
- Identify signs of dehydration
- Perform abdominal and rectal exam
- For diagnosis:
- Obtain complete blood count (CBC), serum albumin, and inflammatory markers
- Erythrocyte sedimentation rate
- C-reactive protein
- Perform sigmoidoscopy
- Edematous mucosa with mucopus and erosions
- Deep ulceration and spontaneous bleeding
- Do not perform colonoscopy during severe disease due to risk of perforation
- Perform colonoscopy after treatment and improvement to determine extent of disease
- Exact mechanism and cause of inflammation unknown.
- Obtain complete blood count (CBC), serum albumin, and inflammatory markers
- Location of inflammation:
- Begins in the rectum and moves backwards to the sigmoid colon in a continuous fashion (subtotal colitis)
- Inflammation can extend beyond the rectum and sigmoid colon to include the entire colon (total colitis)
- Treatment goals:
- Alleviate acute symptoms
- Prevent recurrence
- Treatment options:
- Aminosalicylic acid (5-ASA)
- Corticosteroids
- Immunomodulating drugs
- Biologic therapies
- Janus kinase inhibitors
Crohn's Disease
- Crohn's disease affects the entire intestinal wall (transmural inflammation)
- Location of inflammation:
- Can occur anywhere from the mouth to the anus
- Inflammation occurs in a discontinuous and skip lesion pattern—gaps between inflamed areas are normal
- Most common area inflamed is the terminal ileum of the small intestine
- Second most common area is the large intestine
- Inflammation involves macrophages and neutrophils attacking the intestinal wall causing damage. This results in transmural inflammation
- T-cell lymphocytes infiltrate.
- Transmural inflammation forms non-caseating granuloma (indicative of chronic inflammation)
- Exact mechanism and cause of inflammation unknown.
Complications of IBD
-
Crypt abscesses:
- Epithelium of the crypt breaks down and the lumen fills with polymorphonuclear cells
- Can lead to mild fever
- Abscesses can rupture leading to peritonitis.
- Treatment for abscesses
- Intravenous antibiotic therapy
- Drainage to prevent rupture
-
Fistula formation:
- Worsening inflammation causes tunneling between two structures with the lumen of one section of bowel in communication with another section of bowel.
- Location can be anywhere a lesion is adjacent to an area (e.g., fistula between a segment of bowel and the bladder).
- Associated with pain and severe infection
- Usually requires surgical intervention
- Obstruction
-
Malabsorption of vitamins A, D, B12
- Occurs when a patient has had multiple surgical procedures
- Colon cancer
Gastric Ulcer
- Commonly located in the antral region of the stomach
- Increased permeability to hydrogen ions in the stomach mucosa
- Increased amount of acid
- H. pylori infection directly affects mucosa
- Symptoms:
- GI bleeding
- GI discomfort
- Pain that increases after a meal
- Long-standing inflammation can lead to stomach cancer
- Monitoring:
- Serial esophagogastroduodenoscopies (EGD) and biopsy
- Gastric ulcers that progress to gastric cancer may be asymptomatic.
- Monitoring is important for this reason.
- Symptoms of gastric cancer may be non-specific.
- Once symptoms are present, gastric cancer is often advanced and incurable.
- Symptoms of gastric cancer:
- Weight loss
- Abdominal pain
- Dysphagia
- Indigestion
- Heartburn
- Anemia
- Hematemesis
Inflammatory Bowel Disease (IBD)
- Chronic and relapsing
- Origin is unknown but is associated with:
- Genetics
- Alterations of the epithelial barrier functions
- Immune reactions to the intestinal flora
- Abnormal T-cell responses
- Genetic predisposition seems to be triggered by unknown mechanisms.
- Possibly related to infections with:
- Campylobacter
- Salmonella
- Possibly related to infections with:
- Seems to be a combination of both genetic predisposition and environmental factors.
- This combination leads to the immune system attacking the GI tract.
- Common IBD diseases:
- Ulcerative Colitis
- Crohn's Disease
- Symptoms and risk factors overlap
Risk factors for Ulcerative Colitis and Crohn's Disease

- Gallstones
-
Physical exam focuses on:
- Patient's volume status
- Signs of dehydration
- Abdominal tenderness

- Deep ulceration and spontaneous bleeding in severe cases
-
Treatment goals:
- Alleviate acute symptoms
- Prevent reoccurrence
-
Pharmacological management:
- Aminosalicylic acid (5-ASA)
- Corticosteroids
- Immunomodulating drugs
- Biologic therapies
- Janus kinase inhibitors
-
Lesions:
- Begin in the rectum and move backward to the sigmoid colon (subtotal colitis)
- Can extend beyond the rectum and sigmoid colon (total colitis)
-
Complications:
- Crypt abscesses
- Fistula formation
- Obstruction
- Malabsorption of vitamins A, D, B12
- Colon cancer
Crohn’s Disease
-
Lesions:
- Occur anywhere from the mouth to the anus
- Proceed in a discontinuous and skip lesion pattern
- Gaps between inflamed areas are normal
- Most common area of inflammation: terminal ileum of the small intestine
- Second most common area of inflammation: large intestine
-
Pathology:
- Macrophages and neutrophils attack the intestinal wall, causing damage due to inflammation
- Lesions extend through all three layers of the intestinal wall (transmural inflammation)
- T-cell lymphocytes infiltrate to cause transmural inflammation, which overtime, forms non-caseating granulomas (indicating chronic inflammation)
Gastric Ulcers
- Location: Commonly located in the antral region of the stomach
- Pathophysiology: Increased permeability to hydrogen ions in the stomach mucosa increases the amount of acid; H. pylori infection directly affects the mucosa
-
Symptoms:
- GI bleeding
- GI discomfort and pain that increases after a meal
-
Complications:
- Long-standing inflammation can lead to stomach cancer
- Monitoring: Serial esophagogastroduodenoscopies (EGD) and biopsy

- Symptoms include abdominal cramping, fecal urgency, and tenesmus
- May also include extraintestinal symptoms such as arthralgias, arthritis, iritis or uveitis, aphthous skin lesions, or gallstones
- On exam, check for orthostatic blood pressure, pulse, and nutritional state
- Also check for signs of dehydration, abdominal tenderness, and rectal bleeding
- CBC, serum albumin, ESR, and CRP can be useful in diagnosing and monitoring the disease
- Sigmoidoscopy is key for diagnosis, showing edematous mucosa with mucopus and erosions
- In severe cases, deep ulceration and spontaneous bleeding may be present
- Colonoscopy should be avoided if severe due to risks of perforation
- Colonoscopy can be used to determine the extent of the disease once the patient is treated and improved
- Treatment aims to alleviate acute symptoms and prevent recurrence
- Treatment options include aminosalicylic acid (5-ASA), corticosteroids, immunomodulating drugs, biologic therapies, and Janus kinase inhibitors
- The exact cause of inflammation is unknown
- Lesions begin in the rectum and move backward in a continuous fashion (subtotal colitis)
- Can extend beyond the rectum and sigmoid colon to include the entire colon (total colitis)
- Inflammation can occur anywhere from the mouth to the anus in a discontinuous pattern (skip lesions)
- The terminal ileum of the small intestine is the most common site, followed by the large intestine
- Inflammation is characterized by macrophage and neutrophil attack on the intestinal wall causing damage
- Lesions extend through all three layers of the intestinal wall (transmural inflammation)
- T-cell lymphocytes infiltrate to cause transmural inflammation which overtime, forms non-caseating granulomas
- Crypt abscesses can form, leading to mild fever
- Abscesses can rupture, leading to peritonitis
- Fistulae can form between different structures, associated with pain and severe infection
- Obstruction, malabsorption, and colon cancer can also occur
Crohn’s Disease
- Crohn's disease is an inflammatory bowel disease (IBD) with an insidious onset
- Symptoms include intermittent low-grade fever, diarrhea, right lower quadrant (RLQ) pain, and tenderness.
- Similar risk factors as Ulcerative Colitis:
- Age: Diagnosed most often between 15-45 and 60-80 years old
- Family history: Especially if a close relative has the disease
- Smoking: Especially in Crohn’s disease
- High fat diet: Especially in Ulcerative Colitis
- History of Salmonella or Campylobacter infections
Gastric Ulcer
- Commonly located in the antral region of the stomach
- Increased permeability to hydrogen ions and H. pylori infection can contribute to its development
- Symptoms include GI bleeding, GI discomfort, and pain that increases after a meal
- Long-standing inflammation can lead to stomach cancer
- Patients are monitored with serial EGD and biopsy
- Advanced gastric cancer can be asymptomatic, highlighting the importance of serial monitoring
- Once symptoms appear, they are often non-specific and cancer may be advanced and incurable
Inflammatory Bowel Disease (IBD)
- Chronic and relapsing inflammatory condition with an unknown origin
- Associated with genetics, epithelial barrier dysfunction, immune response to intestinal flora, and abnormal T-cell responses
- There is a predisposition for developing IBD, possibly triggered by infections like Campylobacter or Salmonella in the large and/or small intestine.
- Result of a combination of genetic predisposition and environmental factors that lead to the immune system attacking the GI tract.
- The two most common IBDs are Ulcerative Colitis and Crohn's Disease.
- Symptoms and risk factors can overlap.
Ulcerative Colitis
- Chronic inflammatory bowel disease (IBD) affecting the mucosal surface of the colon
- Characterized by erosion and bleeding
- Can involve the entire colon, distal portion, or extend proximally
- Has periods of flare-ups and remissions
- Patients classified as mild, moderate, or severe based on disease severity
- Symptoms include bloody diarrhea, abdominal cramping, fecal urgency, and tenesmus
- May have extra-intestinal symptoms like arthralgias, arthritis, iritis or uveitis, aphthous skin lesions, or gallstones
Diagnosing Ulcerative Colitis
- History: Ask about frequency of stools and presence of rectal bleeding.
- Physical Exam: Assess volume status (orthostatic blood pressure, pulse, and nutritional state), signs of dehydration, abdominal tenderness, and rectal bleeding.
- Laboratory Tests: Complete blood count (CBC), serum albumin, and inflammatory markers (erythrocyte sedimentation rate and C-reactive protein).
- Sigmoidoscopy: Key diagnostic tool. Mucosa will appear edematous with mucopus and erosions. In severe cases, deep ulceration and spontaneous bleeding may be present.
- Colonoscopy: Performed after treatment and improvement to determine the extent of the disease. Not recommended in severe cases due to the risk of perforation.
Treatment
- Goal: Alleviate acute symptoms and prevent reoccurrence.
-
Pharmacological Management:
- Aminosalicylic acid (5-ASA)
- Corticosteroids
- Immunomodulating drugs
- Biologic therapies
- Janus kinase inhibitors
Ulcerative Colitis vs. Crohn's Disease
-
Location of Inflammation:
- Ulcerative Colitis: Begins in the rectum and moves backward to the sigmoid colon, extending continuously (subtotal colitis). Can involve the entire colon (total colitis).
- Crohn's Disease: Occurs anywhere from the mouth to the anus in a discontinuous, skip lesion pattern with normal gaps between inflamed areas. Most common area: terminal ileum of the small intestine; second most common area: large intestine.
Pathology
- Ulcerative Colitis: Inflammation limited to the mucosal layer of the colon.
- Crohn's Disease: Transmural inflammation (all three layers of the intestinal wall), resulting in non-caseating granuloma formation.
Complications
- Crypt Abscesses: Epithelium of the crypt breaks down, lumen fills with polymorphonuclear cells, may cause mild fever. Rupture can lead to peritonitis.
- Fistula Formation: Tunneling between two structures, communication between bowel segments. Can occur anywhere a lesion is adjacent to another area (e.g., bowel-bladder fistula). Associated with pain and severe infection, often requiring surgical intervention.
- Obstruction:
- Malabsorption: Vitamins A, D, B12, especially with multiple surgical procedures.
- Colon Cancer:
Gastric Ulcer
- Location: Antral region of the stomach.
- Increased Permeability to Hydrogen Ions: Leads to increased acid levels.
- H. pylori Infection: Direct effects on the gastric mucosa.
- Symptoms: GI bleeding, GI discomfort, pain that increases after meals.
- Complications: Long-standing inflammation can lead to stomach cancer.
- Monitoring: Serial esophagogastroduodenoscopies (EGD) and biopsies.
- Cancer Progression: May be asymptomatic, emphasizing importance of monitoring. Advanced cancer often presents non-specific symptoms like weight loss, abdominal pain, dysphagia, indigestion, heartburn, anemia, or hematemesis.
Inflammatory Bowel Disease (IBD)
- Chronic and relapsing condition with unknown origin.
- Associated factors:
- Genetics
- Alterations in epithelial barrier functions
- Immune reactions to intestinal flora
- Abnormal T-cell responses
- Possible trigger: Infections (campylobacter or salmonella) in the large and/or small intestine.
