Proctoscopy

 

(also, rectoscopy), in medicine, a diagnostic method that consists in the examination of rectal mucosa with a proctoscope, a steel tube 25–30 cm in length and 1.5–2 cm in diameter equipped with an electric light on a long rod and an ocular.

Proctoscopy is performed with the patient in a knee-elbow position after the preliminary preparation, which consists in the administration of an enema. The proctoscope is inserted slowly and carefully into the anus under visual control. The rectum must be inflated with air in order to have its lumen clearly visible. Proctoscopy makes it possible to detect tumors, ulcers, and cicatricial stenoses, to remove a small amount of tissue for biopsy, to remove rectal polyps, and to perform the electrocoagulation of a polyp. During proctoscopy the mucosae of both the rectum and the distal portion of the sigmoid are examined; the latter procedure is called rectoromanoscopy. Flexible fibercolonoscopes are used in the examination of deeper sections of the large intestine, including the cecum; this procedure is called colonoscopy.

The level of the primary tumor within the rectum was calculated mostly by rigid proctoscopy and/or digital rectal examination and expressed as the distance from the anal verge.
(23) A study has documented 100% negative predictive value of MR imaging for bladder or rectal invasion, suggesting that MR imaging can obviate invasive procedures, such as cystoscopy, proctoscopy, and sigmoidoscopy, and thus can reduce staging costs and morbidity.
This included a digital rectal examination and proctoscopy. Patients were then referred for a carefully directed translabial ultrasound scan of the rectum and anal sphincters.

Other endoscopic procedures and their targets include: bronchoscopy (trachea); colonoscopy (colon and large intestine); laryngoscopy (larynx); proctoscopy (rectum and lower colon); otoscopy (ear canal); cytoscopy (bladder and urinary tract); and gastroscopy (upper gastrointestinal tract).
To signal a fresh start in good relations between Russia and the United States, we gave President Medvedev an actual reset button marked "rectoscopia," or "reset!" But as luck would have it, "rectoscopia" turns out to mean "proctoscopy." (Why did I believe Joe Biden when he said he knew Russian?) But there is, as always, a bright side; Prime Minister Putin has graciously offered Bill and me complementary proctoscopies at South Ural Teaching Hospital, a lovely gesture!
