Diverticular disease assigns to symptomatic and asymptomatic disease with an underlying pathology of colonic diverticula. Predisposing factors for the formation of diverticula include a low-fiber diet and physical inactivity. Approximately 85 percent of patients with diverticula are believed to remain asymptomatic. Symptomatic disease without inflammation is a diagnosis of exclusion requiring colonoscopy because imaging studies cannot discern the significance of diverticula. Fiber supplementation may interrupt progression to symptomatic disease or improve symptoms in patients without inflammation. Comput tomography is make acceptableed for diagnosis when inflammation is instant Antibiotic therapy aimed at anaerobes and gram-negative wands is first-line treatment for diverticulitis. Whether treatment is administered forward an inpatient or outpatient basis is determined according to the clinical status of the patient and his or her ability to tolerate oral intake. Surgical consultation is indicated for disease that does not suit to medical management or for repeated attacks that may be les likely to be agreeable to to medical therapy and have a higher mortality rate. active surgical consultation also should be obtained when there is evidence of abscess formation, fistula formation, obstruction, or delivered perforation.

**********

Diverticular disease includes a representation of conditions sharing the underlying pathology of acquired diverticula of the colon Because diverticular disease flash on the minds almost exclusively in developed countries, it has been dubbed a "disease of Western Civilization." (1)

Acquired diverticula form within the relative weakness in the muscle wall of the colon at the site where arteries (the vasa recta) penetrate the muscularis layer to reach the mucosa and submucosa. Diverticula generally are multiple. Each diverticulum is typically 5 to 10 mm in diameter, moreover at times they can exce 20 mm The in the greatest degree common site is the sigmoid colon although diverticula can appear throughout the large bowel, with right-sided disease being more customary in asians and in patients younger than 60 years. (23) Vegetarians and others who exhaust large amounts of dietary fiber have a lower incidence of diverticula. although the pathogenic mechanisms of diverticular disease are poorly understood, they are clearly related to tangled interactions of colon structure, intestinal motility, diet, and genetic features. (4)

The authentic prevalence of diverticula is unknown, unless in one large observational meditation (5) of 9,086 consecutive patients undergoing colonoscopy for all indications, the overall prevalence of diverticulosis was 27 percent and increased with patient age. Studies performed in the 1970 propose that the prevalence of diverticula may be as high as 60 percent in patients older than 80 years, with no clear sex predilection. Of patients with diverticula, 80 to 85 percent are believed to remain asymptomatic. Three fourths of the remaining 15 to 20 percent of patients have symptomatic diverticular disease with colicky abdominal pain on the other hand no inflammation. the remaining single fourth (or approximately 5 percent of all patients with diverticula) exhibit diverticulitis, and a small number will cause to grow complications of diverticulitis such as abscess formation, fistulas, obstruction, or hemorrhage. (6) Table 1 compares the various diverticular syndromes

Diverticulosis

Diverticulosis is an anatomic diagnosis that describes the port of one or more diverticula. Uncomplicated, asymptomatic diverticulosis typically is diagnosed incidentally and does not require further work-up. Consensus guidelines6 commend a high-fiber diet in these patients to hinder symptomatic diverticular disease, although there are no randomized controll trials to support or repel this strategy.

Symptomatic Diverticular Disease

Symptomatic diverticular disease, also known as symptomatic diverticulosis, is characterized on nonspecific attacks of abdominal pain without evidence of an inflammatory proces This pain typically is colicky in nature, further can be steady, and frequently is relieved by passing flatus or having a bowel change Patients often note that attacks are precipitated on eating. Bloating and changes in bowel habits also can meet the eye and constipation is more belonging to all than diarrhea. Fullness or tendernes in the left lower quadrant, or occasionally a delicate palpable loop of sigmoid colon frequently is appreciated on physical examination. these nonspecific symptoms overlap considerably with those of irritable bowel syndrome; disorders of inhibitory have the direction of of neuromuscular function may play a part in the development of one as well as the other diseases.

PATHOGENESIS

For unknown reasons, single a small percentage of patients with diverticulosis disclose symptomatic diverticular disease. Some researchers have propos that more painful disease is associated with an increased motility index and increased intraluminal compressing (8) Prospective studies (9,10) in men have shown no connection between symptomatic diverticular disease and smoking, caffeine, or alcohol intake, although lack of physical activity appears to play at least an indirect part In a large prospective thought (11) of 43,881 U.S. male health care professionals, an inverse relationship was noted between the consumption of insoluble dietary fiber and the growth of symptomatic diverticular disease.
