Summary
Adult intussusception imaging reveals characteristic findings. Malignant causes are likely in large bowel cases, often requiring surgery, while asymptomatic cases may favor follow-up.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Oncology
Background:
- Intussusception is rare in adults, unlike in children.
- Understanding adult intussusception requires recognizing specific imaging features and causes.
Observation:
- Classical imaging findings for adult intussusception include target sign, mesenteric fat, and a lead point.
- Clinical manifestations vary, often presenting with abdominal pain, nausea, and vomiting.
Findings:
- Malignancy is a frequent underlying cause, particularly colonic adenocarcinoma in large bowel intussusception.
- The lead point is crucial for diagnosis and determining etiology.
Implications:
- Surgical resection with pathologic analysis is indicated for non-resolving or malignant-appearing intussusception.
- Transient intussusception in asymptomatic adults may be managed conservatively with follow-up.
- Accurate imaging interpretation is key to appropriate management and diagnosis of underlying pathology.

01:24Chronic 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...

01:25Chronic Pancreatitis I: Introduction
Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

01:23Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:25Peptic Ulcer Disease III: Clinical Manifestations and Complications
Duodenal UlcersDuodenal ulcers are the most common form of peptic ulcer disease, presenting with chronic, intermittent epigastric pain. Pain typically appears 2–3 hours after meals, especially when the stomach is empty, often waking patients at night. It is characteristically relieved by food or antacids (“pain–food–relief”). Some patients remain asymptomatic until complications like bleeding or perforation emerge, particularly with NSAID or anticoagulant use.Gastric UlcersGastric ulcers share...
