However, EST is associated with a risk of bleeding, perforation, and sphincter of Oddi function disruption. To avoid these risks, endoscopic papillary balloon dilation (EPBD) is an option for CBDS. Sphincter of Oddi function preservation decreases long-term biliary infection and gallstone recurrence. EPBD may have advantages in children who require a long follow up. However, there have been few reports on pediatric cases, particularly in infants. Methods: From September 2017 to December 2023, we performed EPBD for four pediatric CBDSs. The patients were aged from 5 months to 8 years, including two infants aged 5 and 6 months. Furthermore, we reviewed the stone removal rate and complications of 545 ESTs performed at high-volume centers and 13 EPBD-reported cases in children with CBDSs. Results: CBDSs of all patients who underwent EPBD in our institution were successfully removed. No bleeding or perforation was noted; pancreatitis was observed in three patients. In an analysis of 545 ESTs in children, the stone removal rate was high, ranging from 83% to 100% (mean 96%). The incidence of pancreatitis was 0\u20139.6% (mean 4.4%), and the grade of pancreatitis was almost mild. The bleeding frequency was 1.3\u20135.4% (mean 2.7%). With regards to the grade of bleeding, seven cases were mild (64%) and four were moderate (36%). Compared with adults who underwent EST, the frequencies of pancreatitis and bleeding were almost equal in children; however, in children, once bleeding occurs, it has a higher risk of leading to blood transfusion. Stone removal via EPBD in children has a 100% success rate. Pancreatitis was responsible for all complications were related; its frequency was 46% (6\/13 patients, including five mild cases and one moderate case), which is higher than that of EST and adult cases who underwent EPBD. In most children with pancreatitis, pancreatic enzyme levels returned to normal within 2\u20133 days following EPBD, and no severe cases caused by EPBD were reported. Conclusions: CBDS removal via EPBD in children has a high success rate with very low risk of bleeding and perforation. Although pancreatitis frequently occurs, most cases are mild. Sphincter of Oddi function preservation via EPBD is expected to prevent long-term stone recurrence and biliary tract infection, and EPBD is considered to be an effective method for CBDS removal in children.<\/jats:p>","DOI":"10.3390\/jcm13082251","type":"journal-article","created":{"date-parts":[[2024,4,12]],"date-time":"2024-04-12T09:28:06Z","timestamp":1712914086000},"page":"2251","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Case Series of Endoscopic Papillary Balloon Dilation for Children with Common Bile Duct Stones and a Review of the Literature"],"prefix":"10.3390","volume":"13","author":[{"given":"Katsunori","family":"Kouchi","sequence":"first","affiliation":[{"name":"Department of Pediatric Surgery, Tokyo Women\u2019s Medical University, Ohwadashinden 477-96, Yachiyo 276-8524, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-2109-386X","authenticated-orcid":false,"given":"Ayako","family":"Takenouchi","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, Tokyo Women\u2019s Medical University, Ohwadashinden 477-96, Yachiyo 276-8524, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aki","family":"Matsuoka","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, Tokyo Women\u2019s Medical University, Ohwadashinden 477-96, Yachiyo 276-8524, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoaki","family":"Yabe","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, Tokyo Women\u2019s Medical University, Ohwadashinden 477-96, Yachiyo 276-8524, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroko","family":"Yoshizawa","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, Tokyo Women\u2019s Medical University, Ohwadashinden 477-96, Yachiyo 276-8524, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chikako","family":"Nakata","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, Tokyo Women\u2019s Medical University, Ohwadashinden 477-96, Yachiyo 276-8524, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9451-8318","authenticated-orcid":false,"given":"Jun","family":"Fujishiro","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery, Tokyo University, Hongou 7-3-1, Bunkyou-ku, Tokyo 113-8655, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harutoshi","family":"Sugiyama","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Tokyo Women\u2019s Medical University, 8-1 Shinjuku-ku, Tokyo 162-8666, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,12]]},"reference":[{"key":"ref_1","first-page":"1378","article-title":"Gallstone prevalence and gallbladder volume in children and adolescents: An epidemiological ultrasonographic survey and relationship to body mass index","volume":"84","author":"Palasciano","year":"1989","journal-title":"Am.
