摘要:

&NA;Bleeding from esophageal varices is a devastating complication of portal hypertension and is associated with a high mortality rate. The management goals for this group of patients are to achieve hemostasis in the acute phase, reduce variceal size, reduce the potential of rebleeding and eliminate varices with a follow‐up program. For the past two decades, the gold standard of treatment has been endoscopic sclerotherapy but at the expense of many complications, which often cause serious morbidity. Endoscopic variceal ligation was developed as an alternative to endoscopic sclerotherapy. The experience to date shows that the goals of therapy can be achieved with fewer complications than those associated with sclerotherapy.

摘要:

&NA;Endoscopy units in 27 large teaching hospitals in Canada were surveyed to ascertain which solution was being used to soak endoscopic equipment. The purpose of this survey was to discover if staff in endoscopy units were experiencing side effects as a result of exposure to the soaking solutions. The type of solution used, the use of washing machines and the addition of ventilation are examined in relation to the side effects experienced. The results of the survey showed that five solutions were being used by GI units to soak and clean scopes. All five of the solutions contained some glutaraldehyde, and side effects were reported by staff using all five solutions. The use of washing machines and additional ventilation at some of the hospitals may have had an effect on the number of side effects experienced, but the results could not be used to determine their effect conclusively.

摘要:

&NA;Anorectal dysfunction can be an extreme embarrassment and inconvenience to persons afflicted with the condition, disrupting their lifestyle. Evaluation of the anal sphincter and the distinction between muscular and neural etiology is essential. Three‐dimensional imaging of the anal sphincter by use of anorectal manometry with an eight‐port perfused catheter combined with computer analysis aids in defining anal sphincter function. The use of three‐dimensional imaging is valuable to the physician in the determination of the presence of a muscular defect, the location of the defect and the appropriateness of surgical intervention to resolve the anal dysfunction.

摘要:

&NA;Low‐profile gastrostomy replacement devices (LPGRDs), also called gastrostomy buttons, provide patients with a desirable alternative to traditional catheters. Contraindications to LPGRDs include acutely angled gastrostomy tracts, tracts created with a mucosa lining, the need for jejunal feedings or significant decompression, planned retroesophageal dilation and tracts that are longer than the LPGRDs. Gastrostomy and patient considerations lead to a variety of scheduling practices. Management adaptations help maintain LPGRD patency and functioning of the anti‐reflux valve and plug. Other adaptations are necessary for patients receiving thickened feedings or medications per gastrostomy, needing intermittent decompression or having high intra‐abdominal pressure. Determining the correct LPGRD size and dilating the tract or cauterizing conclude this discussion which is summarized in a checklist following the text.
