Unsuccessful attempts at endoscopic retrograde cholangiopancreatography are usually attributed to duodenal stenosis
Our cannulation rate was 216 out of 220 (98%) since 5 patients had come for review of previous stents and cannulation failed in 4 cases due to duodenal stenosis
At ERCP, 169 cases (76%) including 5 old ones had CBD stones, 12 (5%) had GB stones , 8 (4%) had CD stones, 7 (3%) had CBD stricture and 10 had ( 5 %) dilated biliary ducts only.
Situs ambiguus, Ivemark (14) syndrome, duodenal stenosis
Brown et Duodenal atresia al.
Annular pancreas is a rare congenital malformation that manifests itself primarily by signs related to duodenal stenosis
The fibrotic tissue may narrow the common bile duct, and the cysts may lead to duodenal stenosis
Intestinal malrotation was associated with 80% of these cases, situs inversus with 40%, pancreatic malformations with 33%, and biliary atresia, duodenal stenosis
or atresia with 13%.
Ohno K, Nakamura T, Azuma T, Yoshida T, Hayashi H, Nakahira M, Nishigaki K, Kawahira Y, Ueno TE valuation of the portal vein after duodenoduodenostomy for congenital duodenal stenosis
associated with the preduodenal superior mesenteric vein, situs inversus, polysplenia, and malrotation.
Differential diagnosis of this sign, detected either prenatally or postnatally, includes duodenal atresia, annular pancreas, duodenal stenosis
, duodenal webs, and midgut volvulus.
Indications of surgery in TCP include: severe, intractable pain, pancreatitis associated complications of adjacent organs, distal common bile duct stenosis, duodenal stenosis
, segmental portal hypertension, pancreatic pseudocyst with ductal pathology, internal pancreatic fistula and pancreatic ascites, exclusion of malignancy despite extensive workup, progressive destruction of the organ despite conservative treatment and, occasionally, progressive ill health and problems arising from malnutrition.
There is an increased incidence of gut abnormalities including omphalocaele, gastrochisis, duodenal stenosis
and Hirschprung's disease.
