Q

• A large portion of this patients bowel (arrows) has protruded through an unnatural opening within the abdominal wall. This is called an____ and it is estimated that about 5% of the population will develop an abdominal wall hernia.

A

Hernia: Inguinal

22
Q

This type of obstruction is caused by a weakening of the abdominal wall that allows a portion of the small and/or large intestine to protrude through it.

A

Hernia

23
Q

A common hernia in men is called an

A

inguinal hernia.

24
Q

This is the second category for bowel obstructions. •A mechanical obstruction is caused by a motility disorder that results from some type of structural abnormality. Many factors can contribute to a mechanical bowel obstruction and some of them are listed below:

A

MECHANICAL BOWEL OBSTRUCTION:

25
Q

:
This type of bowel obstruction is caused by a reduction in the normal peristaltic action of the intestines.
• This loss of peristalsis will cause the lumen of both the small and large intestines to fill with air and fluid.
• Therefore, the radiographic appearance of air in both the small and large intestines is an indication of this condition.

A

ADYNAMIC OR PARALYTIC ILEUS

26
Q

The two broad categories of bowel obstructions are as follows: ___/___, ___

A

adynamic or paralytic ileus and a mechanical bowel obstruction.

27
Q

:
• This is a hard mass of entangled material found within the stomach or intestines that cannot be digested.

A

BEZOAR

28
Q
  • appearance of adenocarcinoma.
A

APPLE CORE

29
Q

It is generally asymptomatic in the early stages and has generally metastasized to other areas of the body by the time it has been diagnosed.As a result, it has a poor prognosis,UGI studies present thick, Irregular, and rigid (linitis plastica) folds.
•

A

GASTRIC CARCINOMA:

30
Q

3 Treatment includes in gastric carcinoma

A

gastrectomy, chemotherapy, and radiation therapy.

31
Q
  • These are very rare and may be a complication of gastric carcinoma
A

Gastric Ulcers

32
Q

These are located in the duodenum and are much morecommon than gastric ulcers.

A

Peptic Ulcers-

33
Q

is a general term that is used to describe ulcers of the stomach and duodenum.This is usually a chronic disease.

A

PUD

34
Q

is an opportunistic fungus that commonly inhabits the mouth, throat, GI tract and vagina.

A

Candida

35
Q

Candida over grows within the body it can lead to conditions such as ___ and .Immunocompromised patients that are HIV positive or patients on chemotherapy are predisposed to this infection.

A

thrush
candidiasis

36
Q

occurs as the result of a fungus that has affected the esophagus.This is sometimes referred to as thrush.It is an opportunistic infection that is often found in HIV positive and cancer patients due to the state of their suppressed immune system.

A

CANDIDA:

37
Q

(gastric pull-up)
-The affected portion of the esophagus is removed and the stomach is pulled up into the thorax.

A

Esophagogastrectomy

38
Q

Treatment for esophagus cancer

A

Chemotherapy-Radiation Therapy

39
Q

represents 2% of all cancers and there is a high incidence in smokers and alcoholics.
• The prognosis for this cancer is very poor as it has a 5 year survival rate of 25%
• It presents with very “ratty” radiographic appearance on a barium swallow

A

Esophagus cancer

40
Q

ARE DILATED, TORTUOUS VEINS OF THE ESOPHAGUS WHICH MAY RUPTURE.
THEY ARE COMMONLY A RESULT OF PORTAL HYPERTENSION AND/OR LIVER CIRRHOSIS.
ESOPHAGEAL VARIES ARE OFTEN A COMPLICATION OF ALCOHOLISM.

A

ESOPHAGEAL VARICES

41
Q

: opposite of acid reflux
This UGI radiograph demonstrates a condition called achalasia. This is an esophageal motility disorder that is caused by a lack of peristalsis. As a result, the lower esophageal sphincter (LES ) fails to relax during swallowing and the esophagus fills with, in this case, barium

A

ACHALASIA

42
Q

3 Treatment for achalasia

A

bland diet, medication to relax LES surgery, upright position to reduce regurgitation

43
Q

This UGI radiograph demonstrates a condition called ____. This is an esophageal motility disorder that is caused by a lack of peristalsis. As a result, the lower esophageal sphincter (LES ) fails to relax during swallowing and the esophagus fills with, in this case, barium

A

achalasia

44
Q

is commonly associated with a hiatal hernia.
-It is acquired by poor eating habits, obesity, pregnancy, NG tubes, alcohol abuse, tobacco, and as a side effect of morphine.

A

GERD

45
Q

:
This is often abbreviated as GERD and it is also often referred to as heartburn and acid reflux.
This disease is characterized by a backward flow of gastric contents into the esophagus due to an incompatent lower esophageal sphincter (LES).

A

Gastroesophageal Reflux Disease

46
Q

• The protrusion of a portion of the stomach (hernia) through the esophageal opening of the diaphragm (hiatus) is referred to as a hiatal hernia In this particular case (a) is pointing to the fundus of the stomach that has herniated through the esophageal opening in the diaphragm (b).

A

SLIDING HIATAL HERNIA:

47
Q

A hiatal hernia occurs when a portion of the stomach protrudes (herniates) into the thorax through the esophageal opening in the diaphragm.- SLIDING HIATAL HERNIA- most common type of hiatal hernia encountered.

A

HIATAL HERNIA:

48
Q

if very rare but occurs when portion of the stomach herniates into the thorax while the gastroesophageal. Junction remains stationary. This is one of the most common findings on an UGI series.

A

rolling or paraesophageal hiatal hernia

49
Q

arises in the distal esophagus Just superior to the lower esophageal sphincter (LES).They may form as a complication to achalasia.
Diverticula located within the distal 10 cm of the esophagus are referred to as an epiphrenic diverticula(arrow)

A

EPIPHRENIC DIVERTICULUM:

50
Q

:• This type of diverticulum forms in the mid esophagus area. • Traction diverticulum may form due to scarring from pulmonary tuberculosis or an inflammatory process within the mediastinum.

A

TRACTION DIVERTICULUM

51
Q

arise from the posterior wall of the upper esophagus In the area of the pharynx. Although often asymptomatic, they can cause dysphagia (difficulty in swallowing) and halitosis (bad breath).

A

ZENKER DIVERTICULUM:

52
Q

Some common causes of an adynamic ileus are as follows:

A

Anesthesia/Some Medications

Illness
