The guidelines discuss endoscopy in the preoperative patient and the postoperative patient, and appear in the July issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the ASGE.
Endoscopy is a procedure that uses an endoscope, a thin, flexible tube with a light and a lens on the end to look into the esophagus, stomach, duodenum, small intestine, colon, or rectum, in order to diagnose or treat a condition. There are many types of endoscopy, including colonoscopy, sigmoidoscopy, gastroscopy, enteroscopy, and esophogogastroduodenoscopy (EGD). ASGE is known as the profession's leader in setting standards of excellence in endoscopy and is committed to setting the highest-quality standards for GI endoscopy through its safety guidelines and the training of its members so that patients receive the best and safest care possible. The guideline, "Role of Endoscopy in the Bariatric Surgery Patient," was prepared by the ASGE Standards of Practice Committee.
"Obesity in this country is a major health problem that contributes to increased morbidity, mortality and a host of diseases. Bariatric surgery results in durable and significant weight loss," said Jason A. Dominitz, MD, MHS, chair of ASGE's Standards of Practice Committee. "Endoscopy plays an important role in the preoperative bariatric patient to detect and/or treat lesions in the gastrointestinal tract that might potentially affect the type of surgery performed. In addition, endoscopy is used to diagnose and treat many of the postoperative symptoms or conditions the patient may develop."
The role of upper endoscopy in the preoperative evaluation of patients undergoing bariatric surgery may be based, in part, on the presence or absence of symptoms. The rationale for performing an EGD is to identify and treat lesions that affect the type of surgery performed, cause complications in the immediate postoperative period, or result in symptoms after surgery.
When an endoscopy is considered in a patient who has had bariatric surgery, the endoscopist should be aware of the operative procedure performed, the findings on preprocedural imaging studies and they must understand the expected anatomy. The guidelines advise direct communication with the surgeon if possible. Endoscopy in the postoperative patient may be used to evaluate and treat a variety of conditions including: symptoms of nausea, vomiting and abdominal pain; marginal ulcers; gastroesophageal reflux disease (GERD); gastric leaks and gastrogastric fistulas; stenosis (abnormal narrowing of the stomach or intestine); dumping syndrome (rapid emptying from the stomach into the small bowel); bezoars (food that forms into a hard mass); band erosion or slippage; bleeding and anemia; diarrhea and nutritional deficiencies; choledocholithiasis (the presence or formation of gallstones); and weight regain.-American Society for Gastrointestinal Endoscopy
