Cecal Volvulus

Volvulus occurs when an air-filled segment of the colon twists about its mesentery. The

sigmoid colon is involved in up to 90% of cases, but volvulus can involve the cecum !"0%# or transverse colon. $ volvulus may reduce spontaneously, but more commonly produces bowel

obstruction, which can progress to strangulation, gangrene, and perforation. Chronic constipation

may produce a large, redundant colon chronic megacolon# that predisposes to volvulus,

especially if the mesenteric base is narrow.

The symptoms of volvulus are those of acute bowel obstruction. atients present with

abdominal distention, nausea, and vomiting. &ymptoms rapidly progress to generali'ed

abdominal pain and tenderness. (ever and leu)ocytosis are heralds of gangrene and*or 

 perforation. +ccasionally, patients will report a long history of intermittent obstructive symptoms

and distention, suggesting intermittent chronic volvulus.

Cecal volvulus results from nonfiation of the right colon. otation occurs around the

ileocolic blood vessels and vascular impairment occurs early. lain -rays of the abdomen show

a characteristic )idney-shaped, air-filled structure in the left upper uadrant opposite the site of 

obstruction#, and a /astrografin enema confirms obstruction at the level of the volvulus

nli)e sigmoid volvulus, cecal volvulus can almost never be detorsed endoscopically.

1oreover, because vascular compromise occurs early in the course of cecal volvulus, surgical

eploration is necessary when the diagnosis is made. ight hemicolectomy with a primary

ileocolic anastomosis usually can be performed safely and prevents recurrence. &imple detorsion

or detorsion and cecopey are associated with a high rate of recurrence.
