ERCP
ERCP is generally indicated in:

D. Evaluation of pancreatitis of unknown etiology.
E. Preoperative evaluation of the patient with chronic pancreatitis and/or pseudocyst.

GENERAL INDICATIONS STATEMENTS OF UPPER GI-ENDOSCOPY:
The indications and relative contraindications for doing each of the endoscopic procedures are listed in the following.
These guidelines are based on a critical review of available information and broad clinical consensus.
Clinical considerations may justify a course of action at variance with these recommendations.

GI endoscopy is generally indicated:
1. If a change in management is probable based on results of endoscopy.
2. After an empirical trial of therapy for a suspected benign digestive disorder has been unsuccessful.
3. As the initial method of evaluation as an alternative to radiographic studies.
4. When a primary therapeutic procedure is contemplated.

GI endoscopy is generally not indicated:
1. When the risks to patient health or life are judged to outweigh the most favorable benefits of the procedure.
2. When adequate patient cooperation or consent cannot be obtained.
3. When a perforated viscus is known or suspected.

DEFINITION OF GI ENDOSCOPIC PROCEDURES:
Esophagogastroduodenoscopy (EGD) affords an excellent view of mucosal surfaces of the esophagus, stomach, and proximal duodenum. Colonoscopy allows examination of the entire colon and re**um and frequently the terminal ileum. Standard diagnostic functions include inspection, biopsy, photography, and videorecording. Diagnostic observations are made concerning focal benign or malignant lesions, diffuse mucosal changes, luminal obstruction, motility, and extrinsic compression by contiguous structures. Common therapeutic endoscopic procedures include polypectomy, dilation of strictures, stent placement, removal of foreign bodies, gastrostomy, treatment of GI bleeding with injection, banding, coagulation, sclerotherapy, and endoscopic therapy of intestinal metaplasia. Flexible sigmoidoscopy (FS) uses a flexible instrument
to examine the re**um, sigmoid, and a variable length of more proximal colon. Diagnostic and therapeutic interventions include biopsy, hemostasis, hemorrhoidal banding, and stent placement. Endoscopic retrograde cholangiopancreatography
(ERCP) uses endoscopy to identify the major and minor papillae. The biliary and pancreatic ductal systems are cannulated and opacified with contrast material to provide diagnostic information. Other diagnostic tools may be used in conjunction with ERCP including brush cytology, biopsy, intraductal ultrasound (US), cholangioscopy, and pancreatoscopy. Therapeutic maneuvers performed during ERCP include endoscopic sphincterotomy with or without stent placement, removal of choledocholithiasis, and other ancillary techniques for the treatment of pancreatic and biliary duct disease. Endoscopic ultrasound (EUS) is a technique whereby an
US transducer is incorporated into the tip of the endoscope or a probe is passed through the channel of the endoscope. This provides high-resolution images of the GI wall and adjacent structures. Instruments can be passed under US guidance to obtain tissue samples and perform therapy. Enteroscopy allows the visualization of a greater extent
of the small bowel than EGD. Several types of enteroscopes are available: the push enteroscope, which allows tissue sampling and therapy, and deep enteroscopy (eg, balloon-assisted or spiral overtube–assisted enteroscopy),
which achieves much deeper small-bowel examination than standard push enteroscopy. Video capsule endoscopy provides the capability to
visualize the GI tract by transmitting images wirelessly from a disposable capsule to a data recorder worn by the patient. Specialized capsules for imaging the esophagus and small intestine are currently approved by the U.S. Food and Drug Administration (FDA). Natural or***ce transluminal endoscopic surgery (NOTES) is
an investigational surgical procedure that allows transluminal access of endoscopes to extraluminal structures. A variety of novel procedures have been described, although a discussion of NOTES is beyond the scope of this guideline.
