Cap-assisted endoscopy is useful in improving the visualization of some areas of the
gastrointestinal tract [1
A 20-year-old female inpatient underwent endoscopic retrograde cholangiopancreatography
(ERCP) with endoscopic sphincterotomy without immediate complications for choledocholithiasis;
48 hours later she developed upper gastrointestinal bleeding. She presented with bright
red hematemesis, tachycardia, hypotension, and weakness. Her hemoglobin dropped to
7 g/dL (from 13.8 g/dL at baseline).
An urgent upper endoscopy using a front-view endoscope showed no source of bleeding
from esophagus and stomach, but active duodenal bleeding. Because the bleeding site
was suspected to be at the sphincterotomy and a lateral-view endoscope was not available,
we decided to load the endoscope with a transparent straight cap from a six-shooter
multiband variceal ligator (Wilson–Cook Medical, Inc., Winston-Salem, North Carolina,
USA).
We passed into the second portion of duodenum, obtaining a frontal view of the papilla
of Vater and clearly identifying the bleeding point at the sphincterotomy ([Fig. 1
Fig. 1 Active bleeding of papilla of Vater at the edge of the sphincterotomy.
Sclerotherapy of the bleeding vessel with adrenaline 1 : 10 000 (3 mL) injected with
a 25-gauge needle was successful in controlling the hemorrhage ([Fig. 2

An adequate and stable position was obtained with the transparent cap against the
papilla of Vater. We verified satisfactory hemostasis and terminated the procedure
([Fig. 3
Fig. 3 Satisfactory hemostasis.
From the experience of this case, we believe that in situations when a lateral-view
endoscope is not readily available, using a gastroscope armed with a transparent straight
cap can facilitate the endoscopic view of the papilla of Vater and might also bring
some cost saving benefits.
