摘要
Objective To study the clinical features of intraductal papillary mucinous neoplasm of the biliary tract (BT-IPMN) and to analyse the diagnostic and surgical patterns.Method The data of 19 patients with BT-IPMN admitted from Jun.2012 to Jul.2016 were retrospectively analyzed.Results These 19 (2.3％) patients with BT-IPMN came from 815 patients with biliary tract tumors who were treated in our institution.There were 9 males and 10 females.The male to female ratio was 1.0∶ 1.1.The mean age was 60.6 ± 12.9 years with a range from 25 to 78 years.Jaundice (in 10 patients) and abdominal discomfort (in 6 patients) were the most common presenting symptoms.Bile duct dilatation and intraluminal mass were typical preoperative imaging findings.All these 19 patients were diagnosed to have BT-IPMN histopathologically.18 patients underwent surgery in our hospital.Left lateral hepatic sectionectomy or left hepatectomy was performed in 8 patients,pancreaticoduodenectomy in 6,local excision of bile duct and cholangiojejunostomy in 3 and central hepatectomy in 1.The average operating time was 280 minutes and the average amount of intra-operative bleeding was 515 ml.Fourteen patients underwent regional lymph node dissection and 3 positive lymph nodes were detected out of 94 resected lymph nodes.Sixteen patients were followed up from 1 to 51 months with a mean of (25.7 ± 19.5) months.Fourteen of these patients were still surviving.Two patients died 3 and 17 months after operation due to the tumor.Conclusions Intraductal papillary mucinous neoplasm of the biliary tract was very rare.Early diagnosis was not easy.There was a low percentage of lymphatic metastasis.Surgery was the first choice of treatment and complete resection of BT-IPMN was associated with good long-term survival.
