Operating Procedures of the Electrochemotherapy for Treatment of Tumor in Dogs and Cats
Published on: October 24, 2016
Summary
A dog developed peptic esophagitis and duodenal ulcers due to a malignant pancreatic islet cell tumor. This rare gastrinoma in a non-human species may offer a new animal model for studying Zollinger-Ellison syndrome.
Area of Science:
- Veterinary Medicine
- Oncology
- Gastroenterology
Background:
- Peptic esophagitis and duodenal ulceration are uncommon in dogs.
- Malignant pancreatic islet cell tumors can produce hormones like gastrin and ACTH.
- The Zollinger-Ellison syndrome is characterized by excessive gastrin production leading to ulcers.
Purpose of the Study:
- To report an unusual case of peptic esophagitis and duodenal ulceration in a dog.
- To investigate the association between these gastrointestinal lesions and a pancreatic tumor.
- To explore the potential of this case as an animal model for Zollinger-Ellison syndrome.
Main Methods:
- Clinical case reporting.
- Diagnostic imaging (ultrasound, CT).
- Histopathological examination of the pancreatic tumor.
- Hormone level analysis (gastrin, ACTH).
Main Results:
- A malignant pancreatic islet cell tumor was identified.
- The tumor was confirmed to produce both gastrin and ACTH.
- The dog presented with severe peptic esophagitis and duodenal ulceration.
- This represents the first documented case of a gastrinoma in a dog.
Conclusions:
- Malignant pancreatic islet cell tumors producing gastrin and ACTH can cause severe gastrointestinal ulceration in dogs.
- This case highlights the potential for a canine model to study the multifaceted aspects of Zollinger-Ellison syndrome.
- Further research into this animal model could advance understanding of gastrinoma and its metabolic effects.

Barrett 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...

Peptic Ulcer Disease I: Introduction
Peptic Ulcer Disease (PUD) is characterized by mucosal excavation in the esophagus, stomach, pylorus, or duodenum. It can manifest as acute or chronic based on the extent and duration of mucosal involvement.
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Peptic 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.

Pyloric Obstruction
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
Peptic Ulcer Disease I: Introduction
Peptic ulcer disease (PUD) involves breaks in the gastrointestinal tract's mucosal lining, primarily in the stomach and duodenum, with less frequent occurrences in the lower esophagus or near the pylorus.Ulcers can be acute or chronic. Acute ulcers are short-lived with minimal inflammation and heal quickly after the irritant is removed. Chronic ulcers persist, may recur, and often cause scarring due to ongoing tissue damage. Superficial erosions affect only the mucosal layer and are called...
Intestinal Obstruction II: Pathophysiology
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
