Summary
A chronic partial mesenteric volvulus caused intermittent gastrointestinal signs in a Bernese mountain dog. Surgical correction led to a full recovery, resolving vomiting, diarrhea, and weight loss.
Area of Science:
- Veterinary Medicine
- Canine Gastroenterology
- Surgical Pathology
Background:
- Chronic intermittent vomiting, diarrhea, and weight loss are common presenting complaints in dogs.
- Mesenteric volvulus is a rare but serious condition involving the twisting of the intestine.
- Diagnostic challenges exist in identifying partial or intermittent forms of mesenteric volvulus.
Observation:
- An adult Bernese mountain dog presented with a 4-month history of waxing and waning gastrointestinal signs.
- Physical examination and diagnostic workup revealed significant metabolic disturbances including cholestasis, hepatocellular leakage, azotemia, and electrolyte imbalances.
- Exploratory laparotomy was performed to investigate the underlying cause of the chronic clinical signs.
Findings:
- A chronic, partial mesenteric volvulus was identified during laparotomy as the cause of the dog's symptoms.
- Surgical reduction of the mesenteric volvulus was successfully performed.
- The dog exhibited a complete resolution of clinical signs post-operatively.
Implications:
- This case highlights the importance of considering mesenteric volvulus in the differential diagnosis of chronic gastrointestinal disease in dogs.
- Early surgical intervention for mesenteric volvulus can lead to favorable outcomes and complete recovery.
- Understanding the clinical and biochemical presentation can aid in the timely diagnosis of this condition.

01:07Intestinal 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...
01:29Intestinal Obstruction I: Introduction
Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
01:11Pyloric 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...
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:30Acute 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...
01:21Acute Pancreatitis II: Pathophysiology
The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
