Occult Gastrointestinal Bleeding Secondary to Lesions
Frequently Overlooked at Upper Endoscopy
Hiatal Hernia with Cameron Ulcers and Erosions 671
Allan P. Weston
Gastric erosions and ulcerations located at or near the neck of
diaphragmatic hernias are referred to as Cameron erosions or ulcer¬
ations. Identification of these lesions requires a thorough endo
scopic examination of the hernia sac and the gastric mucosa on
the underside of the diaphragmatic aperture. These lesions should
be considered in any patient in whom a hiatal hernia is noted.
These lesions can be solitary or multiple and can present as acute or
chronic gastrointestinal bleeding or simply as an incidental finding.
Concomitant acid peptic disease is frequently found. Treatment is
primarily medical but surgical intervention is necessary in cer¬
tain circumstances.
Gastric Vascular Ectases 681
Francis R. Weiner and Douglas M Simon
Gastric vascular ectases are being increasingly recognized as a
significant source of acute and chronic upper gastrointestinal bleed¬
ing. Upper gastrointestinal endoscopy has not only facilitated the
identification of gastric vascular ectases but has also revolutionized
their therapy. This article reviews recent developments with refer

CLINICS OF NORTH AMERICA VOLUME 6 • NUMBER 4 • OCTOBER 1996 vii
ence to the epidemiology, diagnosis, pathogenesis, and therapy of
gastric vascular ectases.
Portal Hypertensive Gastropathy 697
David E. Bernstein and Richard S. Phillips
Portal hypertensive gastropathy (PHG) is a vascular disorder
commonly seen in cirrhotic patients with portal hypertension. Al¬
though most cases of PHG have little clinical significance, this
entity is being recognized more frequently as a source of overt and
occult upper gastrointestinal bleeding. Unfortunately, it can be
overlooked endoscopically in the patient who has blood within
the gastric lumen or who has gastritis from nonsteroidal anti
inflammatory drug use. In addition, PHG may not be considered
in patients who are not known to be cirrhotics. Given these circum¬
stances, PGH can be a source of recurrent, occult bleeding. This
article reviews the unique endoscopic and histologic characteristics
of PHG, the pathophysiologic factors leading to the development
of PHG, its clinical manifestations, and its treatment.
Rare Causes of Occult Small Intestinal Bleeding, Including
Aortoenteric Fistulas, Small Bowel Tumors, and Small
Bowel Ulcers 709
Roshan M. Bashir and Firas H. Al Kawas
The most common cause for gastrointestinal bleeding of small
bowel origin is angiodysplasia, followed by tumors of the small
intestine, and various other causes, including small bowel ulcers
and aortienteric fistulas. With the advent of improved diagnostic
tests, including push and sonde enteroscopy, timely endoscopic
diagnosis of these rare small bowel lesions has become possible,
enabling the clinician to make better therapeutic decisions. This
article focuses on the rare small bowel sources of intermittent and
chronic gastrointestinal blood loss.
Dieulafoy s Disease 739
Paul Fockens and Guido N. J. Tytgat
Although Dieulafoy s disease was once considered to be a very
rare cause of severe upper gastrointestinal bleeding, advances in
diagnostic possibilities have shown that the incidence is currently
around 2%. Diagnosis is usually made with (often repeated) endo
scopies and endosonography seems also to be valuable in diagnos¬
ing Dieulafoy s disease as well. Endoscopic therapy is currently
successful in over 80% of patients, the others being treated with
surgery.

Endoscopic Methods and Therapeutic Modalities
Peroral Colonoscopy: Technique, Depth, and Yield of Lesions 753
John S. Goff
Examination of portions of the small bowel beyond the reach of
standard upper endoscopes can be done using peroral passage of
a colonoscope. Important information can be obtained and directed
biopsies and treatment of bleeding lesions can be performed.
Push Enteroscopy: Technique, Depth, and Yield of Insertion 759
Alexander Wilmer and Paul Rutgeerts
Push enteroscopy has evolved into a practical procedure for diag¬
nosing a wide variety of clinical situations with an acceptably high
diagnostic and therapeutic success. Push enteroscopes routinely
allow excellent visualization of approximately 50% of small bowel
mucosa. The range of endoscopic diagnostic and therapeutic possi¬
bilities includes tissue diagnosis through biopsies, polypectomy,
laser therapy, stricture dilatation, and placement of percutaneous
jejunostomies. The diagnostic yield is highest for screening the
upper gastrointestinal tract in polyposis syndromes and for occult
gastrointestinal bleeding. The most successful therapeutic use is
for placing percutaneous jejunostomies.
Sonde Enteroscopy: Technique, Depth of Insertion, and
Yield of Lesions 777
Christopher J. Gostout
Sonde enteroscopy provides the only opportunity to directly view
the contents and mucosa of potentially the entire small intestine.
Although the instrumentation and technique are less than ideal,
sonde enteroscopy can be a useful adjunct to the evaluation of
small intestinal disease. A comprehensive review of this labor
intensive procedure from patient selection to its outcome is pro¬
vided in this article.
Intraoperative Enteroscopy: Indications and Techniques 793
David R. Cave and Jeffery S. Cooley
This article reviews the role on intraoperative enteroscopy (IOI;)
in the management and evaluation of patients with chronic
transfusion dependent gastrointestinal bleeding who have not re¬
sponded to standard diagnostic and therapeutic techniques. Intra¬
operative enteroscopy may be performed with a standard or pediat
ric colonoscope, push enteroscope, or a sonde enteroscope at the
CONTENTS ix
time of laparotomy. IOE techniques as well as indications, diagnos¬
tic and therapeutic capabilities, and complications of this procedure
are discussed.
Enteroscopy with Enteroclysis 803
Giuseppe Aliperti, Gary R. Zuckerman, Jeff R. Willis, and
James Brink
The authors conclude that their experiences support the conclusion
that the combination of enteroscopy and enterocysis is safe and
offers quality small bowel examinations in a more comfortable
and convenient single diagnostic setting. Although enteroclysis
has identified bleeding sources in only 8% of patients who under¬
went this study, other lesions than angiodysplasia were confidently
excluded in the remainder of patients. The combined procedure
is well tolerated in the outpatient setting, more comfortable, and
safer by decreasing radiation exposures than enteroclysis alone.
Use of small bowel enteroscopy at an earlier stage in the evaluation
of patients with obscure gastrointestinal bleeding increases cost
effectiveness without compromising quality.
Enteroscopy: Outcomes 811
Vivek Huilgol, M. Scott Harris, and Nimish Vakil
Outcomes studies are important to determine the role of enteros¬
copy in the management of patients with obscure gastrointestinal
bleeding. This article discusses the current available data and iden¬
tifies areas for further research.
Pharmacologic Therapy of Arteriovenous Malformations 819
Eric Van Cutsem and Hubert Piessevaux
Pharmacologic treatment of bleeding gastrointestinal arteriove¬
nous malformations is difficult. These lesions should be treated
pharmacologically only when endoscopic treatment is not success¬
ful and bleeding persists or when the lesions cannot be treated
endoscopically due to their localization, mainly in the small bowel.
These are only a limited number of studies available on the medical
treatment of bleeding arteriovenous malformations. There is con¬
siderable evidence, however, that a combination of estrogens and
progestagens significantly reduces the bleeding frequency and in¬
tensity and also the transfusion requirements in patients with high
transfusion need. A few other drugs have been tried in patients
with bleeding gastrointestinal arteriovenous malformations: dana
zol, octreotide, desmopressin, and aminocaproic acid. The experi¬
ence with these drugs, however, is limited to case reports or to
small series of patients.

Occult Gastrointestinal Bleeding: General Overview
and Approach 833
Victor R. Mujica and Jamie S. Barkin
Occult gastrointestinal bleeding is most commonly defined as an
acute or chronic loss of blood, the source of which has not been
identified after gastroscopy, colonoscopy, and upper gastrointesti¬
nal series have been performed. As the title suggests, this article
provides a general overview of this disorder. Specific topics dis¬
cussed include etiology, diagnostic procedures, laboratory studies,
radiologic procedures, radionuclide studies, angiography, and en
doscopy.
