Lipomatosis Duodenal

An 88-year-old male, who underwent endoscopy of the upper digestive tract due to a dyspeptic syndrome, signs of chronic atrophic gastritis and multiple duodenal lipomas are found.

Lipomas of the gastrointestinal tract are rare. Duodenal lipomas are incidental and mostly asymptomatic. Tumours may produce symptoms of abdominal pain and discomfort or cause bleeding due to ulceration or intestinal obstruction due to intussusception. Review of cases published in last 67 years indicate that duodenal lipomas are rare to occur but commonly found in second part, they may be seen in third and fourth part of duodenum which may be missed on endoscopy. They can be multiple and may present as severe UGI bleeding which could be managed surgically. Though CT is diagnostic, histopathology confirms the diagnosis which shows lipomatous lesion composed of mature adipose arranged in lobules.

Ectopic opening of the common bile duct (CBD) into The Duodenal Bulb.

Small hole of which bile emerges at anterior wall of duodenal bulb.

The GI tract is an extremely rare congenital anomaly. The clinical implications and frequency of this anomaly are not clearly known.

Although an ectopic opening of the CBD is rare, it may be associated with severe pancreaticobiliary disorders. Endoscopists should be aware of this anomaly and know what to do in case they encounter the condition. Small hole of which bile emerges at anterior wall of duodenal bulb.

An ectopic opening of the common bile duct in the duodenal bulb is an extremely rare anomaly and one that should not be dismissed as just a benign congenital variant because it is associated with recurrent duodenal ulcer, biliary pain, choledocholithiasis, and recurrent cholangitis. Caution must be exercised before diagnosing such ectopia because duodenal ulcer also can cause a choledochoduodenal fistula. To make the diagnosis of ectopic common bile duct, there must be no evidence of a papillary structure in the lower duodenum. A good history, thoughtful endoscopy, and good pancreaticobiliary imaging is key to proper diagnosis.

See in the Gastric Ulcer3 Chapter an ulcero the pre-piloric antrum with probably ectopic opening of CBD.

Duodenal Involvement in Salmonella

Gastroenteritis usually starts 12 to 48 h after ingestion of organisms, with nausea and cramping abdominal pain followed by diarrhea, fever, and sometimes vomiting. Usually the stool is watery but may be a pastelike semisolid. Rarely, mucus or blood is present. The disease is usually mild, lasting 1 to 4 days. Occasionally, a more severe, protracted illness occurs.

If the infection is more severe, a disruption of the intestinal mucosa can occur with necrosis and ulceration, non-typhoidal salmonella.

In rare cases, Salmonella infection mimics inflammatory bowel disease or pseudoappendicitis.

Nontyphoidal Salmonellosis

Prognosis of patients with simple gastroenteritis is excellent except for very young infants or patients with debilitating diseases.

The prognosis for Salmonella meningitis or endocarditis is poor.

Salmonella infection most commonly begins with ingestion of bacteria in contaminated food or water. However, direct contact with animal and human carriers has also been implicated. Reptile and amphibian carriers are the most commonly recognized sources of direct contact Studies involving healthy human volunteers required a median dose of 1 million bacteria to produce disease. However, point outbreaks suggest as few as 200 bacteria may produce nontyphoid gastroenteritis.

 

Duodenal Involvement in Salmonella

Video Endoscopic Sequence 4 of 5.

Salmonella organisms are gram-negative bacilli in the family Enterobacteriaceae. Differences in lipopolysaccharide (LPS) and flagellar structure generate the antigenic variation that is reflected in the more than 2,000 known serotypes. The principal reservoirs for nontyphoidal Salmonella organisms are poultry, livestock, reptiles, and pets. The mode of transmission is ingestion of foods of animal origin, including poultry, red meats, unpasteurized milk, and eggs that have been contaminated by infected animals or an infected human. Contact with infected reptiles, such as iguanas, pet turtles, and tortoises, and ingestion of contaminated water are other modes of transmission.

The tip of this small sessile lesion suggest an early ulceration that is typical for this tumor. In the duodenum, a small submucosal nodule located in the duodenal bulb is typical. In the Ileum, they aregenerally larger and may ulcerate. Most common in middle-aged patients. Duodenal carcinoids may cause obstruction or symptoms due to peptide secretion. Distal small bowel carcinoids cause obstructive symptoms such as abdominal pain, vomiting due to kinking from mesenteric involvement. Ulcerated ileal carcinoids cause acute, episodic, or occult gastrointestinal bleeding.

Duodenal lymphangiectasia

Intestinal lymphangiectasia is characterized by a focal dilatation of intestinal mucocal and submucosal lymphatic ducts and may induce protein-losing enteropathy, steatorrhea, lymphocytopenia, chylous ascites, hypocalcemia, etc. Since transient “functional” duodenal lymphangiectasia (DL) was firstly described in healthy volunteers after nasogastric olive oil infusion, there were several reports describing endoscopic evidence of DL in patients without clinical evidence of malabsorption.

White tips to the intestinal villi are commonly seen but
even after histological examination the cause is not always
clear. Often this is due to endoscopically visible normal
filled lacteals as shown. Recent ingestion of fat-containing
fluids or food is the likely explanation in most cases.
It may in some patients be associated with obstruction to
lymphatic flow.

DL without evidence of clinically significant malabsorption
is not infrequently found during routine upper endoscopies.

Pancreatic Cancer that Infiltrates the Duodenal Wall.

The cat scan showed a tumor of the head, this nodule is in the second part of the duodenum that was proven to be by biopsies adenocarcinoma.

Among cancers of the gastrointestinal tract, it is the third
most common malignancy and the fifth leading cause of
cancer-related mortality. The disease is difficult to
diagnose in its early stages, and most patients have
incurable disease by the time they present with symptoms.
The overall 5-year survival rate for this disease is less
than 5%.

small intestine in patient with HIV disease, typically
presents with weight loss, fever, diarrhea and abdominal
paint. The duodenum is most commonly involved in 90% of
the cases.

Brun ner's Gland Adenoma

Brunner's gland adenoma (BGA) of the duodenum appear
to be nodular hyperplasia of the normal Brunner's gland
with an unusual admixture of normal tissues, including
ducts, adipose tissue and lymphoid tissue.

Overgrowth of Brunner's gland forming a tumour larger
than 1cm in size in diameter is referred to as BGA and less
than 1cm as Brunner's gland hyperplasia.

The etiology of Brunner's gland adenoma remains obscure.
Concurrent H. pylori infection is very common in patients
with Brunner's gland adenoma. However, the role of H.
pylori infection in the pathogenesis and development of
Brunner's gland hyperplasia remains unclear.

Endoscopy of Brunner's Gland Adenoma

Normal Brunner's glands are found in the highest concentration in the proximal duodenum and found normally extending to the proximal jejunum. These glands secrete a viscous alkaline fluid that is thought to protect the duodenal mucosa from the effects of gastric acid. This fluid also contains a glycoprotein that binds to the mucosa to further protect it. Brunner's glands also secrete enterogastrone, a hormone that inhibits gastric acid secretion. The precise etiology of Brunner's gland hyperplasia has not been completely elucidated. One theory is that the glands are stimulated to proliferate by increased acid production. However, no studies have confirmed this hypothesis.

Brunner's gland adenomas are rare duodenal lesions that can present with hemorrhage or signs and symptoms of obstruction. They are not true adenomas, but are actually hamartomas with little to no malignant potential. These lesions should be treated with endoscopic polypectomy if possible, but surgical resection is an acceptable option.

 

Video Endoscopic Sequence 3 of 4.

Brunner’s glands consist of submucosal mucin-secreting
glands located exclusively in the duodenum. They extend
from the pylorus distally for a variable distance, usually at
the first and second portions of the duodenum, and less
frequently, stopping at the third and fourth portions.
Brunner’s glands secrete an alkaline fluid composed of
viscous mucin, whose function appears to protect the
duodenal epithelium from acid chyme of the stomach.
It is a tumor without malignant predisposition. The
malignant type is rare.

Las glándulas de Brunner, localizadas en la submucosa y
las capas profundas de la mucosa del duodeno, son más
numerosas en la primera porción del duodeno, y su número
decrece progresivamente en la segunda, tercera y cuarta
porción. Debido a su localización profunda, la proliferación
de las glándulas de Brunner dan como resultado una masa
submucosa. Histologicamente, las glándulas de Brunner
son las glándulas submucosas acinotubulares ramificadas,
revestidas por grandes células que muestran el citoplasma
tejido ligeramente con la tinción de hematoxilina-eosina.
Cambios quisticos pueden ocurrir dentro del acini y la
atipia celular no está presente por lo general.
