However, incomplete clearance of residual\/microstones post-treatment may cause symptom recurrence. We hypothesized that the 8-wire biliary basket catheter could be suitable for MPD stone extraction and aimed to analyze its ability to achieve more complete clearance of MPD residual\/microstones.<\/jats:p><jats:p>\n            Patients and methods Patients suspected of having MPD residual\/microstones \u2264 5 mm because of abdominal symptoms, computed tomography examination results, and pancreatography results after previous therapy, including ERCP, EHL, and extracorporeal shock wave lithotripsy, were retrospectively enrolled. Patients with severe MPD stenosis\/biliary obstruction requiring ERCP drainage were excluded. Extraction of residual\/microstones was attempted using an 8-wire basket that is widely expandable in the narrow pancreatic duct and can capture and sweep stones in the narrow pancreatic duct. Technical success was defined as extraction of residual\/microstones. The primary outcome was the technical success rate. Secondary outcomes were therapeutic details of stone extraction using the 8-wire basket catheter, including symptom improvements.<\/jats:p><jats:p>\n            Results The technical success rate was 100% for seven patients; 1 to 8 residual\/microstones were extracted. An improvement was observed in five patients with symptoms after the previous therapy. Three patients underwent residual stone extraction after extraction using a dedicated basket. No patient experienced symptom recurrence during the 270-day follow-up period.<\/jats:p><jats:p>\n            Conclusions The 8-wire basket resulted in successful MPD residual\/microstone extraction and pancreatic symptom improvement. This method may prevent symptom recurrence caused by incomplete residual\/microstone clearance.<\/jats:p>","DOI":"10.1055\/a-2453-2494","type":"journal-article","created":{"date-parts":[[2024,10,29]],"date-time":"2024-10-29T00:32:36Z","timestamp":1730161956000},"page":"E1349-E1355","source":"Crossref","is-referenced-by-count":1,"title":["Complete extraction of main pancreatic duct residual and microstones using an 8-wire basket catheter"],"prefix":"10.1055","volume":"12","clinical-trial-number":[{"clinical-trial-number":"umin000052706","registry":"10.18810\/umin-japan"}],"author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4961-3521","authenticated-orcid":false,"given":"Ryota","family":"Sagami","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Oita San-ai Medical Center, Oita, Japan"},{"name":"Department of Gastroenterology, Faculty of Medicine, Oita University, Oita, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiro","family":"Mizukami","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Faculty of Medicine, Oita University, Oita, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidefumi","family":"Nishikiori","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Oita San-ai Medical Center, Oita, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takao","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Oita San-ai Medical Center, Oita, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazunari","family":"Murakami","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Faculty of Medicine, Oita University, Oita, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2024,11,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"153","DOI":"10.1177\/2050640616684695","article-title":"United European Gastroenterology evidence-based guidelines for the diagnosis and therapy of chronic pancreatitis (HaPanEU)","volume":"5","author":"JM L\u00f6hr","year":"2017","journal-title":"United European Gastroenterol J"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"179","DOI":"10.1055\/a-0822-0832","article-title":"Endoscopic treatment of chronic pancreatitis: European Society of Gastrointestinal Endoscopy (ESGE) Guideline -
