Case report
Intestinal bowel perforation by migrated biliary or pancreatic stent is a rare complication
that can occur anywhere in the gastrointestinal tract [1]
[2]
[3]
[4]
[5]. We report two patients with intestinal perforation and bacterial peritonitis secondary
to a migrated stent from the common bile duct and pancreatic duct.
A 43-year-old male with chronic pancreatitis, who underwent an endoscopic cystogastrostomy
for a pseudocyst and stenting of the pancreatic duct after extracorporeal shock wave
lithotripsy for pancreatic calcifications, was transferred to our institution for
treatment of bacterial peritonitis with Streptococcus sp. On admission he was febrile, hypotensive, and had a painful distended abdomen.
Blood test revealed leukocytosis and cholestasis. Abdominal computed tomography (CT)
scan showed ascites, intra-abdominal free air, two pigtail stents still in situ in
the cystogastrostomy, and migration of a pancreatic stent with duodenal perforation
([Fig. 1]).

duodenum, ascites, intra-abdominal free air, and pancreatic calcifications.
Treatment consisted of endoscopic removal of the perforating stent and pigtail stents,
percutaneous drainage of purulent ascites, intravenous antibiotics, bowel rest, and
parenteral feeding. The patient recovered fully and was discharged from the hospital
14 days later.
The second case was that of a 71-year-old female patient with peritoneal dialysis,
who underwent endoscopic retrograde cholangiopancreatography (ERCP) with biliary stenting
for obstructive cholangitis. Three weeks later she developed bacterial peritonitis
with Enterococcus sp., Klebsiella oxytoca, and Candida albicans. Abdominal CT scan revealed perforation of the ileum by the migrated biliary stent
([Fig. 2] and [3]). Because she developed septic shock, the biliary stent was surgically removed and
primary repair of the ileal perforation was performed. The patient is still recovering.

the ileal wall.
The possibility of intestinal bowel perforation secondary to migrated biliary or pancreatic
stent should be considered in patients presenting with abdominal pain after ERCP placement
of stents. The choice between surgical vs. conservative management should be individualized
and depends on the size and site of the perforation and any co-morbidity in the patient
[2]
