Diverticulitis is defined as an inflammation of one or more diverticula. Fecal material or undigested food particles may collect in a diverticulum. Obstruction of the neck of the diverticulum results in distension of the pouch secondary to mucous secretion and overgrowth of normal colonic bacteria. The thin-walled diverticulum, consisting solely of mucosa, is susceptible to vascular compromise and subsequent microperforation or macroperforation. This perforation may be the initiating event leading to symptomatic diverticular diseases. Disease is frequently mild when pericolic fat and mesentery wall-off a small perforation. More extensive disease leads to abscess formation and rarely, with rupture, to peritonitis.

Diverticular Colitis

 Infrequently, patients with diverticular disease develop a
 segmental colitis most commonly in the sigmoid colon. The
 endoscopic and histologic features vary, ranging from mild
 inflammatory changes with submucosal hemorrhages
 (peridiverticular red spots on colonoscopy sometimes
 referred to as "Fawaz spots") to florid, chronic active
 inflammation resembling (histologically and endoscopically)
 inflammatory bowel disease The pathogenesis is
 incompletely understood. The cause may be multifactorial,
 related to mucosal prolapse, fecal stasis, or localized
 ischemia.

Acute diverticulitis is the most common complication of colonic diverticulosis and is one of the most frequently encountered acute diseases of the colon. It begins as a localized intramural infection in a segment affected by diverticulosis, with subsequent development of localized pericolic inflammation. Colonic perforation, abscess formation, or generalized peritonitis may occur Colonic strictures and fistulas to other organs are other important complications. Serious complications are more likely if acute diverticulitis is initially unrecognized or misdiagnosed.

CLINICAL MANIFESTATIONS

 Patients may be asymptomatic or have features resembling those seen in patients with segmental colitis including hematochezia and abdominal pain .

 
Acute diverticulitis traditionally has been considered a disease of patients more than 50 years old by many authorities It has been considered a rare diagnosis in a young adult presenting with abdominal pain, with few reports in the published literature. In one report, acute diverticulitis was considered more aggressive in younger patients than in older adults.

 DIAGNOSIS Diagnosis is made histologically and endoscopically. The differential diagnosis includes inflammatory bowel disease, infectious colitis, NSAID-induced colitis, and ischemic colitis, which can usually be distinguished based upon the clinical context. However, distinction from IBD may not always be straightforward particularly since the histologic features of IBD (such as neutrophilic cryptitis, crypt abscesses and distorted crypt architecture) may all be present. Evidence of Crohn's disease elsewhere in the gastrointestinal tract can provide an important clue.
The clinical presentation of diverticulitis depends on the location of the affected diverticulum, the severity of the inflammatory process, and the presence of complications. Because diverticula and, hence, diverticulitis can develop anywhere in the gastrointestinal tract, symptoms may mimic multiple conditions.

Diverticulitis in the right colon or in a redundant sigmoid colon may be mistaken for acute appendicitis. Diverticulitis in the transverse colon may mimic peptic ulcer disease, pancreatitis, or cholecystitis. Retroperitoneal involvement may present similar to renal disease. In women, lower quadrant pain may be difficult to distinguish from a gynecological process. Mild diverticulitis presents with localized abdominal pain, commonly left lower quadrant pain. Pain is often described as crampy and may be associated with a change in bowel habits. A microperforation, most likely walled-off by adjacent structures, may present with no systemic signs of illness or infection.

The sigmoid colon, where colonic intraluminal pressures are greatest, is most commonly affected. Depending on the location of the affected diverticulum, abscesses may form peritoneally or retroperitoneally. The sigmoid and transverse colon and the anterior surface of the ascending and descending colon are intraperitoneal. The posterior surface of the right and left colon is located retroperitoneally.

Big diverticulum with Fecalith. Diverticula with Fecalith. Diverticulitis is believed to occur when a hardened piece of stool, undigested food, and bacteria (called a fecalith) becomes lodged in a diverticulum. This blockage interferes with the blood supply to the area, and infection sets in.

Big diverticulum with Fecalith.

 Inspissated stool or a fecalith within a thin walled
 diverticulum will cause erosion and inflammation leading to
 infection and perforation. This may vary from a minimal
 peridiverticular phlegmon, which progresses to a
 peridiverticular or mesenteric abscess, which may then
 become a walled off pelvic or intra-abdominal abscess, to
 one that perforates into the free peritoneal cavity causing
 generalized peritonitis. Usually only one diverticulum
 becomes inflamed leading to the different stages of
 inflammation noted.
Diverticular disease is rare in people younger than 40 years. Disease is more virulent in young patients, with a high risk of recurrences or complications. Obesity is an important risk factor in young people.

Intradiverticular diverticulum. Some large diverticula can have a small daughter, inside a sigmoid diverticulum. A diverticulum if there are more than one they are known as diverticula is a protrusion of the inner lining of the intestine through the outer muscular coat, forming a small pouch with a narrow neck. The commonest site for diverticula to develop is the lower left part of the colon. The presence of diverticula is often referred to as diverticulosis. Most diverticula develop during later life and are more and more common with increasing age. But can form anywhere in the large intestine. Once these pouches form they remain for life but frequently cause no problems.

The colonic diverticulum which appears to form as a herniation of intestinal mucosa through defect in the colonic wall where penetration of arterioles (vasa recta) occurs. This places the vasa recta adjacent to the neck of the diverticulum. Trauma the scraping of intestinal contents against the neck and dome of a diverticulum, led to repeated damage of its associated vasa recta with weakening and predisposition to rupture and massive bleeding.

 Complications of diverticulitis:
    Diverticulitis can lead to complications such as infections,
     perforations or tears, blockages, or bleeding. These
    complications always require treatment to prevent them from
    progressing and causing serious illness.

 Bleeding . When diverticula bleed, blood may appear in
 the toilet or in your stool. Bleeding can be severe, but it
 may stop by itself and not require treatment. Bleeding
 diverticula are caused by a small blood vessel in a
 diverticulum that weakens and finally bursts. If
 the bleeding does not stop, surgery may be necessary.

 Abscess, Perforation and Peritonitis The infection causing
 diverticulitis often clears up after a few days of treatment with
 antibiotics. If the condition gets worse, an abscess may form in
 the colon. An abscess is an infected area with pus that may cause
 swelling and destroy tissue. Sometimes, the infected diverticula
 may develop small holes, called perforations. These perforations
 allow pus to leak out of the colon into the abdominal area. If the
 abscess is small and remains in the colon, it may clear up after
 treatment with antibiotics. If the abscess does not clear up with
 antibiotics, the doctor may need to drain it. To drain the abscess,
 the doctor uses a needle and a small tube called a catheter. The
 doctor inserts the needle through the skin and drains the fluid
 through the catheter. This procedure is called "percutaneous
 catheter drainage" Sometimes surgery is needed to clean the
 abscess and, if necessary, remove part of the colon. A large
 abscess can become a serious problem if the infection leaks out
 and contaminates areas outside the colon. Infection that spreads
 into the abdominal cavity is called peritonitis. Peritonitis requires
 immediate surgery to clean the abdominal cavity and remove the
 damaged part of the colon. Without surgery, peritonitis can be
 fatal.

 Fistula A fistula is an abnormal connection of tissue between two
 organs or between an organ and the skin. When damaged tissues
 come into contact with each other during infection, they
 sometimes stick together. If they heal that way, a fistula forms.
 When diverticulitis-related infection spreads outside the colon, the
 colon's tissue may stick to nearby tissues. The most common
 organs involved are the urinary bladder, small intestine, and skin.
 The most common type of fistula occurs between the bladder and
 the colon. It affects men more than women. This type of fistula
 can result in a severe, long-lasting infection of the urinary tract.
 The problem can be corrected with surgery to remove the fistula
 and the affected part of the colon.

 Intestinal Obstruction The scarring caused by infection may
 cause partial or total blockage of the large intestine. When this
 happens, the colon is unable to move bowel contents normally.
 When the obstruction totally blocks the intestine, emergency
 surgery is necessary. Partial blockage is not an emergency, so the
 surgery to correct it can be planned.
Perforation as a complication of acute diverticulitis. There is a continuum of perforation from micro perforation, which is presumably an igniting step in acute diverticulitis and which occurs well before there is evolution to a visible peridiverticular abscess.
