A colonic overtube for maintaining a sigmoid colon in a straightened configuration has a proximal end for location externally of a colon, and a distal end for insertion into a colon. A colonoscope lumen extends through the overtube to facilitate passing the overtube over a colonoscope. The overtube has a convoluted corrugation which extends along the entire length of the overtube from the proximal end to the distal end. The corrugated configuration of the overtube provides the overtube with laterally flexibility so that the overtube may flex substantially without kinking during advancement of the overtube through a colon. A flexible seal, in the form of a tubular silicone sheath of film material, is provided at the distal end of the overtube for sealing between the overtube and a colonoscope extending through the colonoscope lumen. The flexible nature of the seal enables the seal to adapt itself to the size of the colonoscope extending through the colonoscope lumen to achieve a secure, effective seal between the overtube and a colonoscope regardless of the colonoscope size.

A medical instrument used as a sigmoidoscope (1) for internal examination of the rectum and sigmoid colon of a patient. The instrument includes an outer tubular member in the form of a speculum (2) having a forward insertion end (3) and a rearward observation end (4). An inner tapered guide tube (10) is disposed at least partially within the speculum (2). A retractable obturation tube (15) is disposed between the speculum (2) and the inner guide tube (10) for relative movement between a retracted position substantially within the speculum (2) and an extended position in which the obturation tube (15) protrudes longitudinally beyond the forward end (3) of the speculum (2).

A method for inserting an endoscope into the colon of a patient includes providing a generally rigid insert having proximal and distal ends and having a curved channel passing therethrough with a lateral opening at the distal end. The insert is inserted into the patient's rectum so that the distal end is in proximity to the sigmoid flexure of the colon. The endoscope is then passed through the channel and into the sigmoid colon.

A sigmoidoscope (1) adapted for use in conjunction with a removable obturator to facilitate internal examination of the sigmoid colon of a patient. The sigmoidoscope includes a generally tubular speculum (2) having a sidewall defining a forward insertion end (3), a rearward observation end (4) and an internal lumen (5). The lumen (5) defines a substantially unobstructed viewing path between the observation end and the insertion end. Manually operable insufflation means (10) in fluid communication with the lumen of the speculum are provided for insufflation of the sigmoid colon with an insufflation medium. A coupling element (20) has a proximal end (21) for releasable connection to the observation end (4) of the speculum, a distal end (26) adapted for releasable connection to an optical head (30), and an optically transparent observation window (32) effectively isolating the distal end from the proximal end. The coupling element (20) is adapted upon connection to substantially seal the observation end of the speculum and to prevent direct contact between the optical head (30) and the speculum, without visually obstructing the viewing path.

Disclosed are diagnostic tests helpful in indicating presence of an inflammatory bowel disease (IBD) in a human patient. In one embodiment, the test comprises obtaining a sample of mucosal tissue from the ileum or sigmoid colon of the patient; evaluating sample quality by testing for cadaverine and continuing the diagnostic test if the sample has no detectable cadaverine; testing the cadaverine negative sample for N-acetylated spermine; and correlating a detectable level of N-acetylated spermine in the sample with presence of IBD in the patient. Another, less invasive, method disclosed includes a diagnostic test comprising isolating mononuclear leukocytes from the patient's blood; testing the isolated mononuclear leukocytes for level of spermidine; and correlating a level of spermidine higher than that in mononuclear leukocytes of normal subjects as indicative of an inflammatory bowel disease in the patient.
