    Diverticulosis

    The presence of multiple noninflamed diverticula in the colon.

    Diverticulitis

    Inflammation of diverticula that may lead to complications like perforation.

    Common location for diverticula

    Diverticula are most common in the left (descending, sigmoid) colon.

    Lifestyle risk factors

    Diet low in fiber, obesity, inactivity, smoking increase diverticular disease risk.

    Study Notes

    Diverticulosis and Diverticulitis

    • Diverticula are sac-like pouches that form in the colon's lining.
    • Diverticulosis is the presence of these non-inflamed pouches.
    • Diverticulitis is the inflammation of one or more diverticula, potentially leading to perforation.
    • Diverticular disease ranges from asymptomatic diverticulosis to complicated diverticulitis with complications like perforation, abscesses, fistulas, and bleeding.
    • Diverticula are prevalent in older adults, but many never experience diverticulitis.

    Etiology and Pathophysiology

    • Diverticula are most common in the left colon (descending and sigmoid).
    • They develop at weak points in the intestinal wall where blood vessels pass through.
    • Likely caused by genetic and environmental factors, primarily diet and lifestyle.
    • Western, industrialized diets low in fiber and high in red meat and refined carbohydrates are linked to increased risk.
    • Vegetarians have a lower risk.
    • Other risk factors include obesity, inactivity, smoking, excessive alcohol use, and NSAID use.

    Clinical Manifestations and Complications

    • Most diverticulosis cases are asymptomatic.
    • Symptoms in symptomatic cases typically include abdominal pain, bloating, flatulence, and alterations in bowel habits.
    • Diverticula can bleed or lead to diverticulitis.
    • Diverticulitis symptoms commonly include acute pain in the left lower abdomen, distention, decreased or absent bowel sounds, nausea, vomiting, and systemic infection signs.
    • Older adults with diverticulitis may lack fever and have normal white blood cell counts and minimal abdominal tenderness.
    • Diverticulitis can erode the bowel wall and perforate into the peritoneum.
    • A localized abscess forms when the body walls off the perforation site.
    • Peritonitis develops if the abscess cannot be contained.
    • Bleeding is possible but usually resolves spontaneously.

    Diagnostic Studies

    • Diverticular disease may be detected incidentally during routine colonoscopy or sigmoidoscopy.
    • Diverticulitis diagnosis relies on physical exam, complete blood count (CBC), and imaging.
    • Computed tomography (CT) scan with oral contrast is the preferred diagnostic tool.
    • Other options include abdominal X-rays, ultrasound, and MRI.

    Interprofessional and Nursing Care

    • Acute diverticulitis treatment focuses on allowing the colon to rest and inflammation to subside.
    • Some patients can be managed at home with a clear liquid diet, bed rest, and pain medication.
    • Hospitalization is required for severe symptoms, inability to tolerate oral fluids, systemic infection symptoms (fever, significant ↑ WBC), or co-morbid conditions.
    • Recurrent diverticulitis or complications (abscess, obstruction) may need surgical intervention.
    • Surgery often involves colon resection with primary anastomosis.
    • Temporary colostomy is used if an anastomosis is not possible.
    • Colostomy is reversed when the colon has healed.
    • Educating patients about the disease and treatment is important, as adherence to treatment and good understanding often reduce exacerbations.
    • Patients should follow a high-fiber diet (primarily fruits and vegetables), reduce fat and red meat intake.
    • A minimum 2 liters of daily fluid intake is recommended.
    • Avoiding increased intra-abdominal pressure (straining, vomiting, bending, heavy lifting, tight clothing) is crucial.
    • In cases of obesity, weight loss is important. Encourage smoking cessation.

    Complications of Diverticulitis

    • Hemorrhage
    • General peritonitis
    • Fistula
    • Intestinal obstruction
    • Local suppuration
    • Stricture
    • Acute and chronic conditions

    Diagnostic Assessments

    • Medical history and physical exam
    • Stool test for occult blood
    • Complete blood count (CBC)
    • Urinalysis
    • CT scan with oral contrast
    • Abdominal and/or chest X-ray
    • MRI
    • Ultrasound

    Management

    • Conservative therapy: high-fiber diet, fiber supplements, weight loss (if overweight), smoking cessation
    • Acute care (diverticulitis): antibiotic therapy, NPO status, intravenous (IV) fluids, analgesics, and possible nasogastric (NG) suction, surgery, resection of involved colon, and possible temporary colostomy.
