Zollinger-Ellison syndrome: current concepts and management
Annals of Internal Medicine
|January 1, 1983
Summary
Management of Zollinger-Ellison syndrome has evolved with improved diagnosis and medical control of gastric acid hypersecretion. Focus now shifts to gastrinoma localization and treatment, with medical therapies reducing the need for surgery.
Area of Science:
- Endocrinology
- Gastroenterology
- Oncology
Background:
- Zollinger-Ellison syndrome is characterized by gastric acid hypersecretion due to a gastrin-producing tumor.
- Advances in diagnostics and therapeutics have significantly altered patient management strategies.
Purpose of the Study:
- To review the evolving diagnostic criteria and management approaches for Zollinger-Ellison syndrome.
- To highlight the impact of new therapies on patient outcomes and future research directions.
Main Methods:
- Review of recent literature on Zollinger-Ellison syndrome diagnosis and treatment.
- Analysis of the role of gastrin radioimmunoassays and histamine H2-receptor antagonists.
- Discussion of emerging tumor localization and chemotherapeutic strategies.
Main Results:
- Gastrin radioimmunoassays have refined diagnostic criteria and understanding of mimickers.
- Histamine H2-receptor antagonists effectively control gastric acid hypersecretion, reducing the need for total gastrectomy.
- Increased focus on gastrinoma natural history, localization, and chemotherapy due to reduced mortality from acid hypersecretion.
Conclusions:
- Modern management of Zollinger-Ellison syndrome emphasizes medical control of acid hypersecretion and targeted gastrinoma treatment.
- Surgical and chemotherapeutic interventions are increasingly important for gastrinoma management.
- Further research into tumor localization and effective chemotherapy is warranted.

01:28Esophageal Perforation-II: Clinical Manifestations and Management
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:21Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

01:26Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

01:28Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

01:26Peptic Ulcer Disease IV: Management
Medical treatment strategies for peptic ulcers encompass various methods. The primary goal of treatment is to diminish gastric acidity and strengthen mucosal defense mechanisms.
The therapeutic approach involves ensuring adequate rest, implementing drug therapy, promoting smoking cessation, making dietary modifications, and emphasizing long-term follow-up care.
Pharmacological management
The prevailing therapy for peptic ulcers involves a combination of managing the patient's current medication...

01:21Inflammatory Bowel Disease V: Surgical Management
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
