Dolichocolon (redundant colon) is an underdiagnosed cause of severe constipation in humans. The clinical presentation reported here in a rhesus macaque closely resembles that of intestinal adenocarcinoma, the most common neoplasia in macaques. Dolichocolon should be considered in differential diagnosis of macaques with anorexia, weight loss, and constipation.

Redundant colon, also referred to as "dolichocolon," is an anatomical variant associated with elongation and redundancy thought to be associated with constipation, abdominal pain, and distention. Diagnosis requires radiological visualization of the non-dilated colon in situ via barium enema or abdominopelvic computed tomography (CT). Colonic redundancy is based on 3 criteria: sigmoid loop displaced cranially relative to the iliac crests (type 1); transverse colon caudal to the iliac crests (type 2); and redundant loops at the hepatic or splenic flexure (type 3).

Unlabelled: Diffuse intestinal ganglioneuromtosis is a benign tumor of the enteric nervous system, that almost always occurs in children with systemic syndromes. Whereas isolated cases in adults are exceedingly rare.
Case Presentation: A 38-year-old man presented with refractory chronic constipation.

Background: Ventral mesh rectopexy (VMR) is widely accepted for the treatment of rectal prolapse or obstructed defecation. However, despite good anatomical results, the improvement of functional symptoms (constipation or incontinence) cannot always be obtained and in some cases these symptoms may even worsen. The aim of the present study was to identify possible predictors of functional failure after VMR.

The pre-operative work-up for non-metastatic colon cancer includes colonoscopy and thoraco-abdomino-pelvic computed tomography (CT) with intravenous (IV) contrast. Colonoscopic determination of the anatomical location of the tumor may be erroneous, particularly with a long redundant colon (dolichocolon), and the search for synchronous colon neoplasms is limited when the endoscope cannot traverse the tumor-bearing segment. While computed tomography colonography angiography (CTC-A) makes it possible to assess distant tumor metastasis, it remains limited for the assessment of loco-regional extension.
