The purpose of this study is to compare the safety and effectiveness of two types of stem cells,(either banked cord blood or bone marrow), in children between the ages of 2 to 10 years with CP. 15 children with banked cord blood at CBR and 15 children without banked cord blood will be enrolled into the study. The study involves one baseline/treatment visit and 3 follow-up visits at 6 months, 12 months, and 2 years. Five children in each group will be randomized to a placebo control group at the baseline/treatment visit. Parents will not be told if their child received stem cells or a placebo until the 12 month follow-up visit. At that time parents may elect to have their child receive the stem cell treatment; either bone marrow harvest or umbilical cord blood if banked with CBR. All study visits will be conducted at the UTHealth Medical School and Children's Memorial Hermann Hospital in Houston, Texas. As of 1/21/2014 we have met our enrollment limit for children without banked cord blood undergoing bone marrow harvest for stem cells.
NCT05147389
Digital single-operator cholangioscopy (DSOC) findings achieve high diagnostic accuracy for neoplastic bile duct lesions. To date, there is not a universally accepted DSOC classification. Endoscopists' Intra and interobserver agreements vary widely. Cholangiocarcinoma (CCA) assessment through artificial intelligence (AI) tools is almost exclusively for intrahepatic CCA (iCCA). Therefore, more AI tools are necessary for assessing extrahepatic neoplastic bile duct lesions. In Ecuador, the investigators have recently proposed an AI model to classify bile duct lesions during real-time DSOC, which accurately detected malignancy patterns. This research pursues a clinical validation of our AI model for distinguishing between neoplastic and non-neoplastic bile duct lesions, compared with high DSOC experienced endoscopists.
