Appendicitis-I: Introduction

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...

Appendicitis

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic 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.

Chronic Pancreatitis I: Introduction

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...

Chronic Pancreatitis I: Introduction

Chronic 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...

Pyloric Obstruction

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...

Summary

Recurrent abdominal pain after coronary artery bypass grafting may signal celiac trunk stenosis. Prompt diagnosis and treatment, such as angioplasty, can resolve symptoms and improve patient outcomes.

Area of Science:

Cardiology
Vascular Surgery
Gastroenterology

Background:

Coronary artery bypass grafting (CABG) is a common procedure for coronary artery disease.
Abdominal pain can be a complex symptom with multifactorial causes.
Gastroepiploic artery grafts are utilized in CABG procedures.

Observation:

A patient with a history of CABG experienced recurrent abdominal pain.
Initial evaluations focused on gastrointestinal causes without resolution.
A positive stress test prompted further cardiac and vascular investigation.

Findings:

Coronary angiography revealed occluded native coronary arteries but a patent left internal mammary artery (LIMA) bypass.
Aortography demonstrated severe (95%) stenosis of the celiac trunk.
Successful angioplasty and stenting of the celiac trunk restored blood flow.

Implications:

Celiac trunk stenosis should be considered in patients with abdominal pain post-CABG, especially those with gastroepiploic artery grafts.
Vascular assessment of the celiac trunk is crucial in such cases.
Intervention for celiac trunk stenosis can lead to complete symptom resolution and improved quality of life.
