The role of endoscopy in Barrett's esophagus and other premalignant conditions of the esophagus

i ( n d m e This is one of a series of statements discussing the use of GI endoscopy in common clinical situations. The Standards of Practice Committee of the American Society for Gastrointestinal Endoscopy prepared this text. In preparing this guideline, a search of the medical literature was performed using PubMed. Additional references were obtained from the bibliographies of the identified articles and from recommendations of expert consultants. When limited or no data exist from well-designed prospective trials, emphasis is given to results of large series and reports from recognized experts. Guidelines for appropriate use of endoscopy are based on a critical review of the available data and expert consensus at the time the guidelines are drafted. Further controlled clinical studies may be needed to clarify aspects of this guideline. This guideline may be revised as necessary to account for changes in technology, new data, or other aspects of clinical practice. The recommendations were based on reviewed studies and were graded on the strength of the supporting evidence (Table 1).1 The strength of individual recommendations is based on both the aggregate evidence quality and an assessment of the anticipated benefits and harms. Weaker recommendations are indicated by phrases such as “we suggest,” whereas stronger recommendations are typically stated as “we recommend.” This guideline is intended to be an educational device to provide information that may assist endoscopists in providing care to patients. This guideline is not a rule and should not be construed as establishing a legal standard of care or as encouraging, advocating, requiring, or discouraging any particular treatment. Clinical decisions in any particular case involve a complex analysis of the patient’s condition and available courses of action. Therefore, clinical considerations may lead an endoscopist to take a course of action that varies from these guidelines.

EUS-guided transesophageal, transgastric, and transcolonic drainage of intra-abdominal fluid collections and abscesses

BACKGROUND The therapeutic role of EUS is evolving. We report our experience with EUS-guided transesophageal, transgastric, and transcolonic drainage of various intra-abdominal fluid collections. OBJECTIVE To determine the technical feasibility and clinical outcomes of EUS-guided drainage. DESIGN Prospective case series. SETTING Academic tertiary referral center. PATIENTS Patients referred for endoscopic drainage of intra-abdominal fluid collections; pancreatic pseudocysts amenable to conventional transgastric or transduodenal drainage were excluded. INTERVENTIONS Single-step EUS-guided drainage of fluid collections by using a therapeutic linear-array echoendoscope with fluoroscopic guidance. MAIN OUTCOME MEASUREMENTS Technical success, relief of symptoms, and procedural complications. RESULTS Nine consecutive patients deemed appropriate for EUS-guided drainage of intra-abdominal fluid collections included transesophageal drainage of pseudocysts (n = 2), transgastric drainage of biloma (n = 2) and upper intra-abdominal abscesses (n = 2), transcolonic drainage of diverticular abscess (n = 1), Crohns abscess (n = 1), and postoperative hematoma (n = 1). Endoscopic drainage was successful in all patients. Confirmation of complete resolution of the target fluid collection and symptom relief was achieved in 8 (89%) of 9 patients. Pneumothorax and mediastinitis developed in 1 patient after transesophageal drainage, which resolved with chest tube and medical therapy. During multiple stent placement, one of the stents was fully deployed into the abscess cavity in 2 patients; both were successfully retrieved either endoscopically (Crohns abscess) or at the time of primary colonic resection (diverticular abscess). LIMITATION Limited number of patients. CONCLUSIONS EUS-guided transenteric drainage of bilomas, hematomas, abscesses, and inflammatory fluid collections is technically feasible and generally results in complete drainage and symptom relief. Procedural complications may be minimized with more experience.
