Colonoscopy : An examination of the inside of the colon, including the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, and cecum where the small bowel attaches to the large bowel , using an endoscope - a thin, lighted flexible tube inserted through the anus. Sigmoidoscopy : An examination of the inside of the rectum and sigmoid colon using an endoscope - a thin, lighted flexible tube sigmoidoscope inserted through the anus.
Also called flexible sigmoidoscopy and proctosigmoidoscopy. Endoscopy : A procedure using an endoscope to diagnose or treat a condition. There are several types of endoscopy. Those using natural body openings include esophagogastroduodenoscopy EGD which is often called upper endoscopy, gastroscopy, enteroscopy, endoscopic ultrasound EUS , endoscopic retrograde cholangiopancreatography ERCP , colonoscopy, and sigmoidoscopy.
Percutaneous endoscopic gastrostomy PEG is a procedure that utilizes endoscopy to help placement of a tube into the stomach; a small incision in the skin is also required. Endoscopies are usually performed under sedation to assure maximal patient comfort. Enteroscopy : A procedure that allows the visualization of a greater portion of the small bowel than is possible with EGD. Enteroscopy can be achieved by using a long conventional endoscope, a wireless ingestible camera a capsule endoscopy , or a double-balloon endoscope inserted in the mouth or through the rectum.
Endoscopic retrograde cholangiopancreatography ERCP : A procedure using a specific technique to study and treat problems of the ducts involving the liver, pancreas and gallbladder. This procedure utilizes a specialized endoscope with a side-mounted camera that can facilitate passage of a catheter into the bile and pancreatic ducts.
Endoscopic Ultrasound EUS : An examination with a special endoscope fitted with a small ultrasound device on the end, used to look inside the layers of the wall of the gastrointestinal tract and visualize the surrounding organs including the pancreas, liver, gallbladder, spleen and adrenal glands.
The scope is inserted in the mouth or anus in the same manner as a conventional endoscope. Percutaneous Endoscopic Gastrostomy PEG : A procedure through which a flexible feeding tube is placed with the assistance of an endoscope through a small incision in the abdominal wall into the stomach. This procedure is performed in cases where oral ingestion of nourishment or medication is impossible.
Colonoscopy is a common, safe test to examine the lining of the large bowel. During a colonoscopy, doctors who are trained in this procedure endoscopists can also see part of the small intestine small bowel and the end of the GI tract the rectum.
This procedure is often done under sedation to assure maximal patient comfort. During a colonoscopy, the endoscopist uses a flexible tube, about the width of your index finger, fitted with a miniature camera and light source.
This device is connected to a video monitor that the doctor watches while performing the test. Various miniaturized tools can be inserted through the scope to help the doctor obtain samples biopsies of the colon and to perform maneuvers to diagnose or treat conditions.
Colonoscopy can detect and sometimes treat polyps, colorectal bleeding, fissures, strictures, fistulas, foreign bodies, Crohn's Disease, and colorectal cancer.
Sigmoidoscopy, or "flexible sigmoidoscopy," lets a physician examine the lining of the rectum and a portion of the colon large intestine by inserting a flexible tube about the thickness of your finger into the anus and slowly advancing it into the rectum and lower part of the colon. This procedure evaluates only the lower third of the colon.
Sigmoidoscopy is often done without any sedation, although sedation can be used if necessary. Flexible sigmoidoscopy can detect and sometimes treat polyps, rectal bleeding, fissures, strictures, fistulas, foreign bodies, colorectal cancer, and benign and malignant lesions.
Flexible sigmoidoscopy is not a substitute for total colonoscopy when it is indicated. The finding of a new, abnormally growing polyp during sigmoidoscopy, for example, is an indication for a colonoscopy to search for additional polyps or cancer. Sigmoidoscopy should not be used for polypectomy unless the entire colon is adequately prepared.
This procedure should also not be used with cases of diverticulitis and peritonitis. Upper endoscopy allows for examination of the lining of the upper part of the gastrointestinal GI tract, which includes the esophagus, stomach and duodenum first portion of the small intestine. In upper endoscopy, the physician uses a thin, flexible tube called an endoscope. The endoscope has a lens and light source, which projects images on a video monitor.
Upper endoscopy is often done under sedation to assure maximal patient comfort. Upper endoscopy helps the doctor evaluate symptoms of persistent upper abdominal pain, nausea, vomiting or difficulty swallowing. It is the best test for finding the cause of bleeding from the upper GI tract and is also more accurate than X-rays for detecting inflammation, ulcers and tumors of the esophagus, stomach, and duodenum. A physician may also use upper endoscopy to obtain small tissue samples biopsies.
A biopsy helps distinguish between benign and malignant cancerous tissues. Biopsies are taken for many reasons, and a doctor might order a biopsy even if cancer is not suspected. For example, a biopsy can be taken to test for Helicobacter pylori, a bacterium that can cause ulcers and celiac disease, an inflammatory condition of the small bowel that can lead to anemia, weight loss and diarrhea.
Upper endoscopy can also be used to perform a cytology cell test, in which a small brush is passed through the channel of the endoscope to collect cells for analysis. Other instruments can be passed through the endoscope to directly treat many abnormalities with little or no discomfort. For example, the doctor may stretch a narrow area a stricture , detect Barrett's esophagus a possibly precancerous alteration in the esophageal lining , detect and biopsy gastrointestinal cancers, remove polyps usually benign growths , treat bleeding with standard cautery or the newer argon plasma coagulation method , and detect and treat symptoms of gastroesophageal reflux disease GERD.
Enteroscopy includes several types of procedures that allow a physician to look further into the small bowel which is up to 20 feet long than is possible with other methods mentioned here. A physician may use a longer conventional endoscope, a double-balloon endoscope or a capsule endoscope.
Enteroscopy is primarily used to find the source of intestinal bleeding, but can also be used to find lesions and determine causes for nutritional malabsorption. An extended version of the conventional endoscope, called a "push endoscope,"may be employed to study the upper part of the small intestine down to about 40 inches beyond the stomach. While more of the small bowel is accessible with this type of endoscopy than with EGD, it is able to visualize only a limited portion of the small bowel.
The same techniques for therapy used during EGDs are possible during push enteroscopy. Capsule endoscopy uses a swallowable capsule containing tiny video cameras. The capsule, about the size of a large vitamin pill, contains a light source, batteries, a radio transmitter and an antenna. The capsule transmits the images to a recording device worn around the patient's waist.
When complete, the recording is downloaded to a computer which displays it on a screen. The capsule is disposable and usually takes eight hours to move through the digestive system, after which it is passed harmlessly in a bowel movement. Capsule endoscopy does not require sedation and is painless. Capsule endoscopy can be used to diagnose hidden GI bleeding, Crohn's disease, celiac disease, and other malabsorption problems, tumors benign and malignant , vascular malformations, medication injury, and to a lesser extent, esophageal disease.
Currently, capsule endoscopy cannot be used to biopsy or treat any conditions. See also the media backgrounder on capsule endoscopy. Double-balloon enteroscopy uses a basic endoscope for viewing the inside of the entire small bowel, but that endoscope travels inside another tube which is pulled along the inside of the small bowel or colon by alternately inflating and deflating two small balloons against the inside of the intestinal wall.
This allows the scope to travel further, give stable images, perform biopsies, remove polyps, and perform other therapies. This procedure is done under sedation to assure patient comfort. A similar method using a single-balloon device has been recently developed. These procedures can be performed with or without the assistance of an X-ray machine fluoroscopy.
See also the media backgrounder on balloon-assisted enteroscopy. Endoscopic retrograde cholangiopancreatography ERCP is a specialized technique used to study and treat problems of the liver, pancreas and, on occasion, the gallbladder. ERCP is performed under sedation.
Generally, the level of sedation for ERCP is deeper than upper endoscopy and colonoscopy due to the complexity and length of the procedure.
To reach the small passageways, known as ducts, that connect these organs, an endoscope is passed through the mouth, beyond the stomach and into the small intestine duodenum. The ducts from the liver and pancreas drain into the duodenum via a small opening known as the papilla.
A thin tube catheter is then inserted through the endoscope into the papilla, thereby gaining access to the common bile duct and pancreatic duct that connect the liver and pancreas to the intestine.
A contrast material dye is injected through the catheter and flows into the liver and pancreas, outlining those ducts as X-rays are taken. The X-rays can show narrowing or blockages in the ducts that may be due to a cancer, gallstones or other abnormalities. During the test, a small brush or biopsy forceps can be put through the endoscope to remove cells for study under a microscope.
ERCP can be used to diagnose biliary colic, jaundice, elevated liver enzymes, cholangitis inflammation of a bile duct , pancreatitis inflammation of the pancreas , and bile-duct biliary obstruction due to gallstones choledocholithiasis and cancer.
ERCP can be used to treat gallstones, malignant and benign biliary strictures, cholangitis, pancreatic cancer and pancreatitis. Traditionally, ERCP was used as both a diagnostic and therapeutic endoscopic tool for evaluating diseases of the bile ducts, pancreas and gallbladder.
Cholangioscopy or pancreatoscopy are adjunctive procedures performed during ERCP for selected indications, in which miniature endoscopes are passed through the conventional endoscope, to enable direct visualization of the inner lining of the bile ducts and pancreatic ducts respectively.
These procedures permit the endoscopist to obtain tissue specimens directly from the inner lining of the ducts and are also used to treat stones that are difficult to remove using conventional techniques. A flexible endoscope which has a small ultrasound device built into the end can be used to see the lining and wall of the esophagus, stomach, small bowel, or colon. The ultrasound component produces sound waves that create visual images of the digestive tract which extend beyond the inner surface lining and also allows visualization of adjacent organs.
Endoscopic ultrasound examinations also called endoluminal endosonography may be performed through the mouth or through the anus. EUS is performed under sedation.
EUS provides more detailed pictures of the digestive tract anatomy. It can be used to evaluate an abnormality below the surface of the inner lining mucosa such as a growth that was detected at a prior endoscopy or by X-ray. EUS, because of its ability to examine the wall layers of the GI tract, provides a detailed picture of the growth, which can help the doctor determine its nature and decide on the best treatment. EUS can also be used to diagnose diseases of the pancreas, bile duct and gallbladder when other tests are inconclusive, and it can be used to determine the stage of cancers.
More importantly, EUS provides a minimally invasive method for acquiring tissue samples from gastrointestinal tumors and lymph nodes that may not be easily accessible by other methods i.
Fine Needle Aspiration FNA can be performed by passing a biopsy needle down the channel of the endoscope and across the intestinal wall under ultrasound guidance to obtain tissue for the diagnosis and staging of cancer.
More recently, EUS has emerged as a therapeutic tool for treating both solid and cystic tumors of the pancreas, alleviating intractable abdominal pain secondary to advanced pancreatic cancer, and obtaining access to the bile ducts and pancreatic duct in cases of failed ERCP.
Percutaneous endoscopic gastrostomy, or PEG, is a procedure during which an endoscope assists the placement of a flexible feeding tube through the abdominal wall and into the stomach.
The PEG procedure is for patients who have difficulty swallowing, problems with their appetite or an inability to take enough nutrition through the mouth. In this procedure, the endoscopist uses a lighted, flexible tube called an endoscope to guide the creation of a small opening through the skin of the abdomen and directly into the stomach.
This allows the doctor to place and secure a feeding tube into the stomach. Patients generally receive a sedative and local anesthesia, and an antibiotic is given by vein prior to the procedure. Patients can usually go home the day of the procedure or the next day. A PEG does not prevent a patient from eating or drinking, but depending on the medical condition and situation, the doctor might decide to limit or completely avoid eating or drinking.
PEG tubes can last for months or years. However, because they can break down or become clogged over extended periods of time, they might need to be replaced.

Rothstein et al commented that the downtime for reprocessing of standard sigmoidoscopes is a major factor in delay between procedures and that a sizable supply of endoscopes is required in order to have an instrument ready for the next patient; therefore, the markedly decreased turnaround time is an important advantage of the sheathed sigmoidoscope system.
Moreover, according to the authors, the high-level disinfection required for standard endoscopes places patients and staff at risk of reactions to disinfection solutions. They also noted that future refinements in the sheathed system will likely improve the features about which the endoscopists in their study expressed concern. Search Contact Us Blogs. Rothstein, R.

Proctoscopy (Rigid Sigmoidoscopy)
See patient information handout on flexible sigmoidoscopy. Office Procedures forms on flexible sigmoidoscopy are provided on page Flexible sigmoidoscopy remains a common tool used for the periodic screening of colorectal cancer. Most organizations recommend screening at three- to five-year intervals beginning at age 50 for persons with average risk.
Extensive training in endoscopic maneuvering, colorectal anatomy and pathologic recognition is required. Most physicians report comfort performing the procedure unsupervised after 10 to 25 precepted sessions. The procedure involves the insertion of the sigmoidoscope through the anus and distal rectum and advancement of the scope tip to an average depth of 48 to 55 cm in the sigmoid colon. Once the sigmoidoscope has been appropriately advanced, the scope is slowly withdrawn, allowing for the inspection of colon mucosa during withdrawal.
Polyps less than 5 mm in diameter should be biopsied. Polyps 5 to 10 mm or greater can be assumed to be adenomatous, and follow-up colonoscopy for complete polypectomy is required. Diverticulosis, hemorrhoids, nonspecific colitis and pseudomembranes may also be encountered during inspection. Use of preprocedural benzodiazepines can be helpful in reducing patient discomfort.
The most promising strategy for reducing the burden of colorectal cancer is periodic screening. Flexible sigmoidoscopy has been widely recommended at intervals of three to five years because of its sensitivity for detecting early cancers and adenomas.
This examination is believed to be a cost-effective intervention for family physicians. In most series, the average depth of insertion of the long flexible sigmoidoscope ranged between 48 and 55 cm. It is thought that about 60 percent of all colorectal cancers are within reach of the sigmoidoscope. The three- to five-year screening interval recommendation is based, in part, on estimates that seven to 10 years are required for an adenoma to progress to malignancy. Most organizations recommend initiating sigmoidoscopy screening at age 50 for persons of average risk.
An important limitation to the effectiveness of screening for colorectal cancer is the ability of patients and physicians to comply with testing. Flexible fiberoptic sigmoidoscopy is considered by many patients to be uncomfortable, embarrassing and expensive, and patients may be reluctant to agree to the testing. Studies of populations that are repeatedly advised to undergo sigmoidoscopy have found that only 10 to 30 percent of persons agree to the procedure.
Physician motivation is important in encouraging patient compliance for undergoing the procedure. Physicians report that the lengthy procedure time and the extensive training needed to master the technique limit their use of the sigmoidoscope. Once a physician becomes experienced in endoscopic techniques, however, sigmoidoscopy procedures can be performed routinely in fewer than 10 minutes.
Confirm that the patient performed the recommended enemas and bowel preparation. The patient should remove clothing from below the waistline and should be seated on the examination table with a disposable sheet draped over the legs.
Place an absorbent sheet beneath the patient on the table. Two or three nonsterile gloves some physicians double-glove the right hand and remove the outer glove after the rectal examination and anoscopy.
The operation of the sigmoidoscope should be checked before the procedure: air should be bubbled into the basin of water, and some of the water suctioned through. Biopsy forceps should be available if in sterile packaging, do not open until the forceps are needed. The patient is placed in the left lateral decubitus position. A rectal examination is performed with the gloved finger, examining the prostate in the male patient and confirming anal patency. The gloved examining finger can be lubricated with 2 percent lidocaine jelly Xylocaine or 5 percent lidocaine ointment to provide topical anesthesia of the anal canal for anoscope and sigmoidoscope insertion.
The lubricated slotted Ive's anoscope is lubricated with water-soluble K-Y jelly or additional lidocaine jelly and inserted into the anal canal.
The three hemorrhoid pads right posterior, right anterior and left lateral should be inspected individually, necessitating insertion of the scope three times, to examine for anal canal pathology. The distal portion of the flexible sigmoid oscope is lubricated with water-soluble jelly, but the jelly is kept off the most distal tip to avoid smearing the lens and distorting the image. The scope is inserted into the rectum, either by direct insertion into the anus or by pushing the scope tip into the anus by flexing the index finger behind the scope.
Once the scope is in the rectum 7 to 15 cm inserted , air is insufflated, fluid that may be present is suctioned, and the lumen is located by moving the tip of the scope. While some examiners have the nurse or assistant insert the scope, better control of the scope tip is achieved if the right hand inserts the scope and rotates the tip to the right and left.
The examiner's left thumb moves the scope tip up and down by moving the inner knob on the scope head. The scope is inserted only while the lumen is visualized.
Attempt to insert the scope as quickly as possible, thereby limiting patient discomfort. Special insertion techniques, such as torquing twisting the scope in the right hand , dithering rapid, short back-and-forth motions to advance the scope , accordionization pulling back on angled portions of colon wall with the scope tip, allowing the scope tip then to advance with the colon folded—like an accordion— onto the scope and hooking and straightening Figure 1 may be required to negotiate the many turns in the sigmoid.
The colon mucosa is inspected as the scope is with drawn, and biopsies are obtained only if needed. Hooking and straightening technique used to pass through a tortuous sigmoid colon. A The scope is inserted to the angled sigmoid. B The scope tip is turned to a sharp angle, and the sigmoid is hooked as the scope is withdrawn.
C The sigmoid is straightened as the scope is withdrawn. The scope can then be inserted through to the descending colon. Once the scope tip is withdrawn to the rectum 10 to 15 cm inserted , the scope tip is retroverted to examine the distal rectal vault. This area is not visualized well by the for ward-directed scope as it is inserted or with drawn.
Retroversion is achieved by maximally deflecting the inner knob with the left thumb while simultaneously inserting the scope with the right hand. This maneuver should pro duce an image of the black scope as it enters the rectum from the anal canal. Air is withdrawn from the rectum before removing the scope. The scope is immediately immersed in a basin of water, and the suction channel is flushed to prevent clogging of this channel by stool that may have entered the channel during the procedure.
The anus is wiped clear with gauze, and the patient is offered the opportunity to go to the bathroom. Once the patient is dressed, he or she can be moved to a chair for postprocedure counseling while the scope is cleaned and disinfected. As the scope is inserted into the rectum, a red-out may develop if the scope tip is pushed up against the colon wall. The scope tip can be slowly withdrawn and air inserted until the lumen appears.
The normal rectal mucosa demonstrates a nonfriable vascular network. Proctitis produces an erythematous, friable mucosa, often with bleeding. Preprocedure enemas given to clear the colon may produce some patchy or streaky erythema, which should not be confused with proctitis. The semilunar valves of Houston generally appear as sharp edges protruding into the lumen, with dark shadows noted behind.
These valves protrude from different sides of the rectum and are more easily seen with air in sufflation or when the scope is withdrawn on exiting the colon. The physician should examine for pathology behind the valves. Ulcerative colitis usually produces erythema, friability and mucosal bleeding, which may extend from the anus upward throughout the colon.
As the scope enters the sigmoid, redundant folds with a loss of vascularity obliterate the lumen. Air insufflation is necessary to identify the lumen.
Extensive turning of the scope tip, torquing, accordionization or dithering techniques may be needed to negotiate the marked sigmoid turns. The examiner should avoid bowing out the sigmoid, which happens when the midscope is inserted into a sigmoid loop but the scope tip fails to advance Figure 2.
Paradoxic insertion. A The scope is bowing out the sigmoid colon, which has a mobile mesenteric attachment. B Paradoxic insertion describes the insertion of the tube without advancement of the scope tip. Paradoxic insertion can be very uncomfortable for the patient. The descending colon appears as a long tube ringed with concentric haustrae.
The vascularity of the descending colon appears as a random reticular pattern. Diverticular openings may be seen here, appearing as dark circles in the colon wall. Polyps may appear as a mound in the mucosa sessile or on a long stalk pedunculated. Because mucus adherent to the colon wall can be mistaken for a sessile polyp, bulges in the wall can be tapped with the scope tip to see if they wipe off.
Colon cancers can often be recognized by the irregular growth or mucosal pattern, or by bleeding or narrowing of the lumen. The splenic flexure sometimes can be reached with the cm sigmoidoscope. The splenic flexure can appear as a dead end and, if the turn is negotiated, the triangular shape to the transverse colon may be visualized.
The last area to be visualized as the scope is withdrawn is the rectal vault. Because the lateral portions of the distal rectum are not well visualized by the forward-directed scope, the scope tip can be retroverted. The scope is seen entering the rectum from the anal canal, and the upper extent of internal hemorrhoids can be identified.
Diminutive polyps less than 5 mm in diameter cannot be classified by visual inspection. All polyps smaller than 5 mm should be sampled for biopsy. If the polyp is hyperplastic, no further treatment is necessary, because hyperplastic polyps are not associated with polyps in the proximal right colon. If the polyp is adenomatous tubular, villous, etc. Larger polyps larger than 5 to 10 mm in diameter generally are adenomatous and do not require a biopsy at sigmoidoscopy because they should be completely removed.
Polypectomy is performed during colonoscopy to facilitate the search for any additional polyps. If a suspected cancer is encountered an irregular, obstructing, friable or bleeding mass , it may be sampled for biopsy, but vigorous bleeding of the lesion may ensue. Prompt referral is suggested. Diverticulosis is believed to result from the colon's exposure to excessive intraluminal pressure. Patients with diverticulosis can be offered stool-bulking agents to soften the stools and reduce stool transit time.
Patients with diverticulosis are often told to avoid nuts and seeds in their diet to prevent an undigested seed from clogging a diverticular opening, although there is little evidence suggesting this.
Hemorrhoids are commonly encountered during sigmoidoscopy. Surgical or ablative therapies can be considered, but the hemorrhoids often shrink with administration of stool-bulking agents and efforts to promote soft stools.
