An 84 year old male with history of melanoma of the scalp diagnosed two years prior, was found to have a splenic lesion on abdominal CT scan. CT scan showed a round, hypoechoic lesion in the spleen as shown by the arrow. Linear EUS examination identified a 2 cm round, hypoechoic, hypovascular and heterogeneous lesion in the spleen as shown by the [...]

In this video we will describe a novel technique of EUS guided choledochoduodenostomy as a 1-step procedure using a echoendoscope. We perform this procedure in patients with unresectable malignancy causing obstructive jaundice. In patients where standard ERCP or EUS guided rendezvous has failed or is not an option. A detailed discussion with th [...]

This is a 61 year old female with a history of pancreatic CA, s/p pylorus preserving Whipple, chemotherapy and radiation 20 years prior. She clinically has no evidence of disease. She has a 2 yr history of recurrent attacks of severe abdominal pain. These attacks of pain were self-limited episodes that lasted several hours. She was ultimately a [...]

Our patient is a 55 year old woman presenting with intermittent episodes of periumbilical abdominal pain and nausea of 2 months duration. She had extensive prior history of abdominal surgeries including ovarian cancer resection complicated by colonic perforation. This was treated with segmental colonic resection and temporizing ileostomy. Subsequ [...]

Biliopancreatic diversion is a morbid obesity surgery in which a long afferent loop is anastomosed to the ileum. It makes peroral ERCP impossible. Intraoperative ERCP through the distal antrum is feasible, and convenient if cholecystectomy is needed. A 72 y.o. female had prior cholecystectomy and biliopancreatic diversion with gastrectomy. She w [...]

ERCP in patients with surgically altered anatomy, in particular Roux-en-Y anastomosis, can be more challenging. The use of balloon overtube-assisted enteroscopy can be useful for ERCP in patients with such surgically altered anatomy. Even using an enteroscope, removing large or multiple stones can be often difficult and time-consuming. Several en [...]

Increased prevalence of morbid obesity has resulted in an increased frequency of Roux-en-Y gastric bypass. Investigation of pancreatic and biliary complaints following roux-Y gastric bypass is difficult secondary to rerouting of the small bowel, a long intestinal limb and limited access to the major papilla; previously only achieved by surgical [...]

Fiber optic and video baby-scopes have been available for many years; however limitations have included fragility, use in ducts less than 10Fr in size, high cost and time spent. This study is to look at a recently introduced reusable fiber optic bundle which will fit through standard ERCP accessories. We wish to examine smaller ducts and see if t [...]

A 65 year old female had multiple episodes of recurrent acute pancreatitis. Endoscopic ultrasound (EUS) examination showed pancreas divisum. From the second portion of the duodenum, the slow withdrawal of the endoscope was performed to visualize the minor papilla. Minor papilla examination was performed in the long position of the endoscope, whi [...]

In this video we will present two cases discussing the technique of bile duct access with pure wire guided cannulation using a loop tip guide wire. For pure wire guided cannulation, a sphincterotome is recommended. We should stay slightly away from the papilla so that papilla is clearly visualized and using the bow of sphincterotome the guide wir [...]
