Author Information Authors Catherine D. Introduction Acute diverticulitis is inflammation due to micro-perforation of a diverticulum. Etiology Risk factors that increase the chances of developing diverticulitis are the same as those related to diverticulosis.

Pathophysiology Diverticulitis is the result of microscopic and macroscopic perforations of the diverticular wall. History and Physical Clinical manifestation of acute diverticulitis varies depending on the severity of the disease. Evaluation Diagnosis of acute diverticulitis can be made clinically based on history and physical examination alone.

Postoperative and Rehabilitation Care After recovering from diverticulitis, the patient must be examined to rule out a malignancy. Deterrence and Patient Education A high-fiber diet can prevent diverticulosis. Enhancing Healthcare Team Outcomes Acute diverticulitis has enormous morbidity and while there are no universal guidelines, expert opinion recommends a multidisciplinary approach for diagnosis and management.

Acute Diverticulitis - StatPearls. Fiber absorbs water as it passes through the intestine, producing bulky stools that move through more quickly, reducing the likelihood of constipation and the resulting pressure in the colon. When fiber is inadequate, stools are small and hard, and the colon must contract with greater force to expel them, putting extra pressure on the colon walls. A high-fiber diet should include a mix of whole grains, nuts, seeds, fruits, legumes such as dried beans , and vegetables. See "Fiber content of various foods.

However, this idea has been disproved. For people who can't or don't consume enough fiber in foods, supplements are available, including psyllium Fiberall, Konsyl, Metamucil, others , methylcellulose Citrucel, generic , and calcium polycarbophil FiberCon. It's important to take these supplements with adequate water — usually at least 8 ounces, preferably more, with each dose. Women should aim for 25 grams of fiber per day 21 grams if you're over age Added fiber can have unpleasant side effects, such as bloating or gas.

To minimize this problem, increase your daily intake gradually, by about 5 grams per week, until you reach your goal. And be sure to drink plenty of fluids.

Regular exercise, especially aerobic exercise, can also help. It speeds the movement of food through the colon, reducing the risk of constipation and the formation of hard, dry stools. Both fiber which is filling and exercise help combat obesity, which has been linked in several reports to the development of diverticulitis and diverticular bleeding. Considering how many millions of Americans have diverticulosis, it's remarkable that complications are so rare. However, they do occur and can be serious. Diverticulitis occurs when the wall of a diverticulum is eroded by pressure, trapped fecal matter, or both.

If the damage is severe enough, a tiny perforation develops in the diverticulum and allows bacteria to infect the surrounding tissues. Usually, the body's immune system is able to confine the infection to a small area on the outside of the colon.

But sometimes the infection develops into an abscess that erodes surrounding tissue, creating fistulas — passageways between the bowel and other structures in the abdominal cavity. Fecal material may spill out of the diverticulum into the abdominal cavity, causing peritonitis infection of the peritoneum, the membrane that lines the abdominal cavity.

Peritonitis is a critical condition that calls for prompt medical attention. The surgeon makes an opening in the abdominal wall a colostomy which helps clear the infection and inflammation. The colon is brought through the opening and all waste is collected in an external bag. The colostomy is usually temporary, but it may be permanent, depending on the severity of the case.

Diverticulitis most often affects the elderly. In Western countries, diverticular disease most commonly involves the sigmoid colon 95 percent of patients. The prevalence of diverticular disease has increased from an estimated 10 percent in the s to between 35 and 50 percent by the late s, and 65 percent of those currently 85 years of age and older can be expected to have some form of diverticular disease of the colon. Less than 5 percent of those aged 40 years and younger may also be affected by diverticular disease.

Left-sided diverticular disease involving the sigmoid colon is most common in the West, while right-sided diverticular disease involving the ascending colon is more common in Asia and Africa.
