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...

Hiatal Hernia

Hiatal Hernia

A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...

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.

Gastric Emptying

Gastric Emptying

Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Summary

This study describes a rare case of parasitic conjoined twins, specifically an epigastric heteropagus twin. Surgical separation was successful, removing a rudimentary parasitic structure from the host infant.

Area of Science:

Medical Case Study
Congenital Anomalies
Perinatology

Background:

Parasitic twinning is a rare congenital condition.
It arises from monozygotic monochorionic monoamniotic asymmetrical conjoined twins.
Epigastric heteropagus twins are a specific subtype.

Observation:

A case of epigastric heteropagus twin is presented.
Ultrasound revealed an epigastric defect of 1.5 cm.
CT scan showed a lobulated soft tissue mass with fat and air components protruding from the defect.

Findings:

Surgical exploration identified a rudimentary alimentary canal within the parasite.
No other viscera were present in the parasitic twin.
The parasite was successfully and easily separated from the host.

Keywords:

Epigastric heteropagus twin Monochorionic monoamniotic Conjoined twin
