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.

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.
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.

Scattered Patches of dark erythematous mucosa. The dark appearance of the patches suggest that the acute phase has passed. Colonic diverticular disease is a common problem in the Western world. The incidence of the disease increases with age but only a minority of these patients are symptomatic. Complications of diverticular disease, however, can cause significant morbidity and mortality. Studies about the natural history of diverticular disease, and the incidence of complications after an initial attack, have reported varying outcomes.

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.

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.

The sigmoid and descending colon show signs of diverticulitis.
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.

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.

A 70 Year- old female, had rectal bleeding. This diverticula was the cause of severe enterorragia. Pathogenesis of a diverticular bleeding. 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.

Close up of the diverticula. Same case as above Diverticular bleeding usually is self-limited but may be recurrent. The bleeding stopped spontaneously. 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.
