Summary
A rare duodenal anomaly, where the lower second part coiled on the right kidney, was found in a cadaver. This anatomical variation highlights potential diagnostic challenges in medical imaging.
Area of Science:
- Gastroenterology
- Anatomy
- Surgical Anatomy
Background:
- Duodenal anatomical variations like atresia and stenosis are documented.
- Gross anomalies in the shape and position of the midgut segment of the duodenum are exceptionally rare.
- Few cases of duodenal anomalies have been reported, with historical records dating back to the early 20th century.
Observation:
- A rare duodenal anomaly was identified in an adult female cadaver.
- The lower half of the second part of the duodenum exhibited a serpentine coiling.
- This anomalous segment was positioned on the upper pole of the right kidney.
Findings:
- The anomalous duodenal segment coursed superiorly, parallel and to the right of the normal upper half of the second part.
- The third part of the duodenum coursed downwards and leftward, posterior to the pancreatic head and neck.
- The anomalous course of the third duodenum segment involved sandwiching the commencement of the portal vein.
Implications:
- This case underscores the importance of recognizing rare duodenal positional anomalies.
- Such variations can lead to misinterpretation of radiological images, impacting diagnosis and surgical planning.
- Awareness of these anomalies is crucial for accurate interpretation in anatomical studies and clinical practice.

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.

01:26Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

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...
01:25Peptic 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...
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,...
01:27Diverticular 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...
