Insights

A duodenal duplication cyst caused failure to thrive in an infant. Surgical resection resolved symptoms and restored adequate growth, highlighting the importance of considering rare gastrointestinal anomalies.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Medical Imaging

Background:

  • Failure to thrive (FTT) in infants can stem from various underlying conditions, necessitating thorough diagnostic evaluation.
  • Gastrointestinal anomalies, though less common, should be considered in the differential diagnosis of persistent FTT and abdominal symptoms.

Observation:

  • An 11-month-old boy presented with a 4-month history of FTT, fever, postprandial abdominal pain, and lethargy.
  • Initial investigations, including contrast-enhanced abdominal computed tomography (CT), suggested a pancreatic pseudocyst, leading to surgical drainage.
  • Recurrent symptoms post-drainage prompted a second CT scan, revealing a duodenal duplication cyst.

Findings:

  • A 6.5-cm duodenal duplication cyst communicating with the fourth part of the duodenum was identified.
  • Complete resection of the duodenal duplication cyst was performed.

Implications:

  • Duodenal duplication cysts are rare congenital anomalies that can present with nonspecific symptoms, mimicking other conditions.
  • Accurate diagnosis and complete surgical excision of duodenal duplication cysts are crucial for symptom resolution and achieving adequate growth in affected infants.
  • This case underscores the importance of advanced imaging and considering a broad differential diagnosis in challenging pediatric cases.

Diverticular Disease of the Colon01:27

Diverticular 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...

Gallbladder

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

Endoscopic 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.
