Study Notes
Constipation
- Primary Causes: Pelvic floor dysfunction, slow transit constipation
- Secondary Causes: Medications (opioids, anticholinergics, calcium supplements), systemic diseases (hypothyroidism, diabetes, Parkinson's), structural abnormalities (strictures, masses)
- Alarm Symptoms: Weight loss, hematochezia, anemia, family history of colorectal cancer
- Management: Dietary changes (increase fiber and fluids), behavioral modifications (regular bowel habits), pharmacotherapy (osmotic agents like PEG and lactulose, stimulants like bisacodyl and senna, secretagogues and serotonin agonists for refractory cases)
Incarcerated vs. Strangulated Hernia
- Incarcerated Hernia: Hernia contents trapped, non-reducible, no compromised blood supply
- Symptoms: Pain, nausea, firm, non-reducible mass
- Strangulated Hernia: Compromised blood supply, ischemia, severe pain, systemic toxicity (fever, tachycardia)
- Management: Surgical emergency, risk of necrosis and perforation
Specific Conditions
Diverticular Disease
- Diverticulosis: Outpouching of the colon, associated with age and low-fiber diet, often asymptomatic or causes chronic constipation/mild pain
- Treatment: High-fiber diet, avoid restrictive diets (seeds/nuts are no longer contraindicated)
- Diverticulitis: Inflammation/infection of diverticula, acute left lower quadrant (LLQ) pain, fever, nausea, changes in bowel habits
- Diagnosis: CT abdomen/pelvis, follow-up colonoscopy after resolution
- Treatment (Mild): Oral antibiotics (e.g., amoxicillin-clavulanate, ciprofloxacin + metronidazole)
- Treatment (Severe): Hospitalization, IV antibiotics, possible drainage or surgery
Anorectal Disorders
- Hemorrhoids (Internal): Painless bleeding, prolapse, treatment includes fiber, sitz baths, topical agents, rubber band ligation, or hemorrhoidectomy
- Hemorrhoids (External): Painful thrombosis, similar treatment to internal hemorrhoids
- Proctitis: Often sexually transmitted (e.g., gonorrhea, chlamydia, HSV), anorectal discomfort, discharge, tenesmus, treatment based on pathogen (antibiotics/antivirals)
- Anal Fissures: Trauma from defecation or intercourse, pain with defecation, hematochezia, treatment includes sitz baths, fiber, nitroglycerin, or botulinum toxin for certain cases
- Anal Fistulae: Often from abscesses, consider Crohn's if recurrent, treatment is fistulotomy, preserving sphincter function
- Perirectal Abscess: Infection of anal crypts, pain, fever, erythema, treatment involves incision and drainage (I&D) with antibiotics if needed
- Rectal Prolapse: Protrusion of rectum, incontinence, treatment is surgical repair
- Fecal Impaction: Rectal fullness, pain, treatment includes manual disimpaction or enema
Hernias
- Inguinal Hernia: Most common, indirect hernias pass through the inguinal ring, repair if symptomatic or incarcerated
- Ventral/Incisional Hernia: Risk factors include obesity, prior surgeries, surgical repair if symptomatic or large
- Umbilical Hernia: Acquired in adults due to increased abdominal pressure, repair if symptomatic
- Femoral Hernia: Higher strangulation risk, always surgically repaired
Screening and Diagnosis of Colorectal Cancer
- Guaiac Testing (FOBT): Detects occult blood, lower sensitivity/specificity
- Fecal Immunochemical Test (FIT): Detects human hemoglobin, more sensitive than FOBT
- Flexible Sigmoidoscopy: Limited to rectosigmoid/descending colon
- Colonoscopy: Gold standard for screening, detection, and removal of polyps
- CT Colonography (Virtual Colonoscopy): Good for large polyps, less sensitive for small polyps
Colorectal Neoplasms
Adenomas
- Precursor to cancer; risk increases with size, villous features, and dysplasia; treatment is polypectomy with surveillance
Polyps
- Types include hyperplastic (benign), adenomatous, serrated; follow-up depends on number and histology
Familial Adenomatous Polyposis (FAP)
- Hundreds of polyps, inevitable cancer by age 50 without surgery; treatment is proctocolectomy with surveillance
Lynch Syndrome (HNPCC)
- Autosomal dominant, rapid polyp progression to malignancy, increased risk of extracolonic cancers, surveillance involves colonoscopy every 1-2 years starting at age 25
Colorectal Cancer
- Symptoms include anemia, hematochezia, bowel habit changes
- Diagnosis includes colonoscopy with biopsy, staging with CT
- Treatment includes surgical resection, chemotherapy for advanced disease
