Guideline for the management of ingested foreign bodies.

This is one of a series of statements discussing the utilization of gastrointestinal 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 MEDLINE literature search was performed, and additional references were obtained from the bibliographies of the identified articles and from recommendations of expert consultants. When little or no data exist from well-designed prospective trials, emphasis is given to results from large series and reports from recognized experts. Guidelines for appropriate utilization of endoscopy are based on a critical review of the available data and expert consensus. Further controlled clinical studies are needed to clarify aspects of this statement, and revision may be necessary as new data appear. Clinical consideration may justify a course of action at variance to these recommendations.

Guideline on the management of anticoagulation and antiplatelet therapy for endoscopic procedures

This is one of a series of statements discussing the practice of gastrointestinal endoscopy in common clinical situations. It is intended to aid endoscopists in determining the appropriate use of endoscopic procedures in conjunction with anticoagulation and/or antiplatelet therapy. Guidelines for the appropriate practice of endoscopy are based on critical review of the available data and expert consensus. Controlled clinical studies would be beneficial to clarify some aspects of this statement and revision might be necessary as new data appear. Clinical consideration may justify a course of action at variance from these specific recommendations.

Endoscopic Ultrasound-Guided Fine-Needle Aspiration Cytology Diagnosis of Solid-Pseudopapillary Tumor of the Pancreas A Rare Neoplasm of Elusive Origin but Characteristic Cytomorphologic Features

Clinical histories, endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) material, and immunohistochemical stains performed on cell block samples of 6 solid-pseudopapillary tumors of the pancreas (SPTPs) were reviewed in the cases of 5 females (13-58 years) and 1 man (57 years); all had abdominal pain. Preliminary cytologic diagnoses at endoscopy included 1 SPTP 2 low-grade neoplasms, and 3 pancreatic endocrine tumors. Variable numbers of branching fragments with central capillaries and myxoid stroma were seen in the smears of 5 of 6 cases but were more apparent in the cell block material of all cases. The cells had bland nuclear features and rare grooves. Extensive necrosis was noted in 1 case and rare mitotic figures in 1. SPTPs showed strong cellular immunoreactivity for vimentin and focal weak keratin reactivity. Neuron-specific enolase, alpha1-antitrypsin, and alpha1-antichymotrypsin stains performed in 2 cases were strongly positive. Subsequent surgical resection confirmed all diagnoses. EUS-guided FNA diagnosis of SPTP is accurate. The characteristic branching papillae with myxoid stroma are best seen in cell block slides. Clinical setting, cytomorphologic features, and immunostains of the cell block help distinguish SPTP from pancreatic endocrine tumors, acinar cell carcinoma, and papillary mucinous carcinoma.

Role of endoscopy in enteral feeding

p n p m i s 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 (ASGE) prepared this text. This guideline updates a previously issued guideline on this topic.1 In preparing this guideline, a search of the medical iterature was performed using PubMed. Additional refernces were obtained from the bibliographies of the identied articles and from recommendations of expert consulants. When few or no data exist from well-designed rospective trials, emphasis is given to results from large eries and reports from recognized experts. Guidelines for ppropriate use of endoscopy are based on a critical reiew of the available data and expert consensus at the time hat the guidelines are drafted. Further controlled clinical tudies may be needed to clarify aspects of this guideline. his guideline may be revised as necessary to account or changes in technology, new data, or other aspects of linical practice. The recommendations are based on eviewed studies and are graded on the strength of the upporting evidence (Table 1).2 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 o provide information that may assist endoscopists in roviding care to patients. This guideline is not a rule and hould not be construed as establishing a legal standard of are or as encouraging, advocating, requiring, or discourging any particular treatment. Clinical decisions in any articular case involve a complex analysis of the patient’s ondition and available courses of action. Therefore, clincal considerations may lead an endoscopist to take a ourse of action that varies from these guidelines.
