RESUMEN
Proper timing of repair is one of key factors predicting long-term prognosis of iatrogenic biliary injury.Local inflammation is proved related to long-term biliary stricture.This article introduces pathological procedure of biliary injury based on pathophysiological mechanism and animal model rescarch of wound healing,and how to increase intraoperative repair rate based on the clinical evidences.The preoperative active inflammation control and systemic management could create necessary conditions for the the subsequent early repair.At the same time,authors suggest to set individual strategy regarding timing of repair.Delayed repair is recommended for combined vascular injury or severe biliary injury with terrible contamination.
RESUMEN
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.
RESUMEN
Objective To evaluate the clinical features and the key points in the diagnosis and management of splenic hemangioma.Methods The clinical presentations,laboratory tests,imaging and pathological results,treatment,and prognosis of 21 cases of splenic hemangioma admitted in Peking Union Medical College Hospital from April,1989 to July 2007 were retrospectively analyzed.Results The clinical presentations of splenic hemangiom are not specific which include left upper quadrant mass or discomfort,abdominal pain,etc.The diagnosis of imaging includes Doppler ultrasound,CT,MRI,DSA,etc.Splencetomy is recommended for all splenic hemangioma with severe symptoms or rupture.Conclusion Asymptomatic patients with small splenic hemangioma(＜4 cm)can be managed conservatively.Symptomatic large hamangioma may need a sp]enectomy.
