Update on treatment of variceal hemorrhage

Improved prognosis for patients hospitalized with esophageal varices in Sweden 1969-2002

Liver cirrhosis may be complicated by the development of esophageal varices. The treatment of esophageal varices has changed radically during the last 30 years. Our aim was to study whether the prognosis for patients with esophageal varices had improved in Sweden between 1969 and 2002. We linked register data from the Hospital Discharge Register and from the Causes of Death Register at The National Board of Health in Sweden between 1969 and 2002 to identify and follow-up all patients with esophageal varices according to International Classification of Diseases-8, -9, and -10. There were 12,281 patients hospitalized with esophageal varices, and for all patients there was an increase in the 5-year survival in the years between 1969 and 1979 as opposed to the years between 1990 and 2002. Better survival occurred for women compared with men, for younger patients compared with older, and for patients hospitalized in the latest decade compared with the earlier decades. We found a significant decrease in the mortality caused by esophageal varices during the years studied but no decrease attributable to other causes. In conclusion, mortality for patients hospitalized with esophageal varices in Sweden decreased between 1969 and 2002. The decrease is seen for both 1- and 5-year mortality, and this suggests that the use of new treatment strategies both for acute variceal hemorrhage and secondary prophylaxis has had an impact on prognosis.

Upper gastrointestinal bleeding

PURPOSE OF REVIEW

This review discusses key issues in the management of upper gastrointestinal bleeding including patient preparation, sedation, hemostatic techniques, disposition, and recommended pharmacologic interventions.

RECENT FINDINGS

Optimal resuscitation before endoscopy and proper pharmacologic interventions after endoscopy seem to be as crucial to the management of patients with upper gastrointestinal bleeding as meticulous hemostatic techniques during the procedure. In a retrospective evaluation of patients with upper gastrointestinal bleeding, multivariate analysis demonstrated significantly reduced morbidity and mortality in those who underwent aggressive preendoscopic resuscitation. In a prospective, randomized clinical trial, patients who received intravenous proton pump inhibitor therapy after endoscopic intervention had a significantly reduced rebleeding rate compared with their placebo control group.

SUMMARY

The algorithms described in this review can be applied clinically today and should directly lead to improved outcome. Nevertheless, even with the latest care available, results are not optimal. This review points to two major areas where we can benefit from improvement: primary hemostasis and recurrent bleeding. By pointing to these limitations, it is hoped that this review can help stimulate research in the field by applying new technologies to solve these problems. Endoscopic ultrasound, for example, could be used to help identify feeding vessels that can be treated endoscopically, thus potentially decreasing the incidence of failed primary hemostasis. Endoscopic suturing, when more fully developed, may provide a better hemostatic technique that can reduce the incidence of recurrent bleeding. It is only through these reviews that our state of knowledge in the field can be constantly reevaluated to update today's clinician with the latest knowledge and stimulate tomorrow's researchers with challenging problems.

Interventional endoscopy

PURPOSE OF REVIEW

This review provides an updated summary of gastric interventional endoscopy. Relevant original articles and topic reviews are highlighted in the areas of infection control, light sedation, hemostasis, endoscopic mucosal resection, and endoscopic placement of enteric devices.

RECENT FINDINGS

Several key findings are worth noting: the increased use of propofol by nonanesthesiologists for deep sedation with minimal adverse side effects, the adaptation of tissue adhesive agents for the treatment of bleeding gastric varices, the successful treatment of early gastric cancer by endoscopic mucosal resection, and the development of direct percutaneous endoscopic jejunostomy tubes for patients at high risk of aspiration.

SUMMARY

These recent developments in the field of interventional endoscopy have already made a great impact on clinical care. More advanced procedures can be performed safely while the patient is under deep sedation. Yet, these developments have not slowed down the need for improvement in interventional endoscopy. Researchers continue to look for smaller instruments, better optics, and more advanced accessories. This constant state of flux marks the field of interventional endoscopy and ensures its progress.
