Different clinical presentations, diagnostic difficulties, and management of cecal duplication.

BACKGROUND

Cecal duplications (CDs) are very rare, representing 0.4% of all gastrointestinal duplications. This study evaluates the variable clinical presentations, imaging workup, and surgical management of CDs.

METHODS

The records of 7 patients who underwent surgery between April 2001 and December 2011 for CD were retrospectively reviewed. Sex, age, duration of complaints, diagnostic studies, surgical intervention, and pathologic findings were recorded.

RESULTS

The median age was 8 months, and mean age was 1.65 ± 2.88 years. Complaints were abdominal pain, rectal bleeding, vomiting, cough and dyspnea, and a prenatally detected cystic mass. The patients were referred with the diagnosis of appendicular abscess, necrotizing enterocolitis, gastrointestinal lymphoma, and intraabdominal cystic mass. Abdominal distention, signs of peritonitis, substernal retraction, fullness at right lower quadrant, and normal findings were detected on physical examination. Diagnostic imaging included plain abdominal radiography (7), ultrasonography (7), computed tomography (3), and magnetic resonance imaging (2). A cystic mass was reported on radiologic studies in 6 patients and appendicular abscess in 1. Cyst and cecum were resected, ileocolostomy was performed in 6 patients, and cyst excision was performed in 1. The diagnosis of duplication cyst was made by pathologic examination in all patients.

CONCLUSIONS

Cecal duplications may be detected incidentally; however, they may mimic appendicular abscess, a tumor mass, or necrotizing enterocolitis. Whether cystic lesions are symptomatic, they should be excised when detected because of possible complications.
