Colonoscopy revealed pseudomembranous colitis extending from the ascending colon to the cecum, and Clostridium Difficile, toxin was positive in the feces. The administration of vancomycin in addition to oral steroids resulted in rapid improvement of the condition.

UC is marked by diffuse, superficial inflammation of the colonic mucosa, beginning in the rectum and extending proximally to involve any contiguous length of colon. The small intestine is not involved, except in the setting of extensive colitis, in which the most distal terminal ileum may exhibit similar superficial inflammation, termed backwash ileitis. Because the extent of colitis usually remains constant from the onset, the length of involved colon defines the classification of UC: proctitis (limited to the rectum), proctosigmoiditis or left-sided colitis (extending up to the splenic flexure), or pancolitis (extending into the transverse colon).

This is the case of a patient with long standing ulcerative colitis, male 37 year-old.

 UC is marked by diffuse, superficial inflammation of the
 colonic mucosa, beginning in the rectum and extending
 proximally to involve any contiguous length of colon. The
 small intestine is not involved, except in the setting of
 extensive colitis, in which the most distal terminal ileum
 may exhibit similar superficial inflammation, termed
 backwash ileitis. Because the extent of colitis usually
 remains constant from the onset, the length of involved
 colon defines the classification of UC: proctitis (limited to
 the rectum), proctosigmoiditis or left-sided colitis
 (extending up to the splenic flexure), or pancolitis
 (extending into the transverse colon).

A depressed ulcer is observed,  Proximal extension occurs in approximately one third of patients with distal disease, and regression from pancolitis is also possible The extent of involvement does not necessarily imply severity but does pertain to prognosis (e.g., the risk of cancer) and to treatment selection. The symptoms and course of UC relate to both the extent and the severity of inflammation within the involved segment of colon.

 symptoms and course of UC relate to both the extent and
 the severity of inflammation within the involved segment of
 colon.

Extensive colitis (pancolitis). In pancolitis, inflammation extends into the transverse or right colon. Patients are more likely to present with diarrhea because of diminished absorptive capacity of the colon, accompanied by rectal bleeding and urgency. Abdominal cramps may be diffuse or localized, and patients are more likely to have weight loss, systemic or extraintestinal symptoms, and anemia.

 The severity of UC depends on both the length of colon
 involved and the severity of colonic inflammation.

The cecum, the Ileocecal valve, Clinical Severity, Mild. In mild UC, patients have less than four bowel movements daily, with minimal cramps and urgency. Usually, most of the bowel movements occur early in the day; and after the morning evacuations, the patient is able to proceed with activities of daily life.

Clinical Severity

 Mild. In mild UC, patients have less than four bowel
 movements daily, with minimal cramps and urgency.
 Usually, most of the bowel movements occur early in the
 day; and after the morning evacuations, the patient is able
 to proceed with activities of daily life.

 

Clinical Severity: Moderate. Patients with moderate UC have four to eight bowel movements daily, more frequent rectal urgency, and postprandial cramping and bowel movements. Blood is present in most stools, and nocturnal wakening for bowel movements is common. The disease can interfere with daily work or school activities and social life.

The cecum.

 Clinical Severity: Moderate. Patients with moderate UC have
 four to eight bowel movements daily, more frequent rectal
 urgency, and postprandial cramping and bowel movements.
 Blood is present in most stools, and nocturnal wakening for
 bowel movements is common. The disease can interfere with
 daily work or school activities and social life.

 Severe. Patients with severe UC have more than eight bowel
 movements daily, nocturnal bowel movements, severe urgency
 with or without incontinence, and systemic signs that include
 low -grade fever, night sweats, weakness, and weight loss.
 Abdominal tenderness, tachycardia, anemia, leukocytosis, and
 hypoalbuminemia are common.

 Fulminant. Patients with fulminant colitis have more than 10
 bowel movements a day, nocturnal bowel movements, severe
 abdominal pain or relentless tenesmus, and rebound tenderness
 or distention with tympanic bowel sounds. They also have
 prostration, high fever, and hypotension. Radiographic studies
 show evidence of mucosal edema, intramural air (pneumatosis
 coli), colonic dilatation (toxic megacolon), or free abdominal air
 (perforation).

 Ulcerative Colitis. Moderate to severe colitis is characterized by granularity, friability, exudate, spontaneous bleeding  and  increasingly larger areas of ulceration. Pathophysiology: Ulcerative colitis is defined as continuous idiopathic inflammation of the colonic or rectal mucosa. The rectum is involved in more than 95% of cases. Some authorities believe that the rectum is always involved in an untreated patient. Partial healing may occur in a patient treated with topical therapy, creating diagnostic confusion.

Ulcerative Colitis. Necrosis, edema, exudate and friability are observed. Causes: An unknown factor causes an immune-mediated inflammatory response in the intestinal mucosa. Genetic susceptibility (chromosomes 12 and 16) is a factor associated with ulcerative colitis. A positive family history (observed in 1 of 6 relatives) is         associated with a higher risk for developing the disease. Smoking is not associated with ulcerative colitis This relationship is reversed in Crohn disease.
