Abstract

Insights

Acute mesenteric ischemia (AMI) is more common in older adults than previously thought. Early diagnosis with CT scans is crucial for better outcomes in elderly patients with acute abdomen.

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Geriatrics

Background:

  • Acute mesenteric ischemia (AMI) incidence rises sharply with age.
  • AMI's role in elderly acute abdomen cases may be underestimated.

Purpose of the Study:

  • To determine the incidence of AMI in an elderly population.
  • To compare AMI incidence with other acute abdominal conditions.
  • To assess long-term mortality in AMI survivors.

Main Methods:

  • Retrospective analysis of hospitalized AMI patients (2009-2013).
  • Calculation of age-specific incidence rates for AMI and reference diagnoses.
  • Assessment of long-term mortality risk for AMI survivors.

Main Results:

  • In-hospital AMI incidence: 7.3/100,000/year.
  • AMI incidence exceeds ruptured abdominal aortic aneurysm.
  • AMI incidence is higher than appendicitis in patients >75 years.
  • AMI survivors face 1.8x higher mortality risk than acute cholecystitis survivors.

Conclusions:

  • AMI is a significant cause of acute abdomen in the elderly.
  • Urgent contrast-enhanced CT is vital for diagnosing AMI in this demographic.

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Peptic Ulcer01:27

Peptic Ulcer

Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the...
