原发胆道结石与胰胆管合流异常关系的临床初步研究 总被引:2,自引:0,他引:2
原发胆道结石多为胆红素钙结石,其病因未明,一般认为与胆道感染,胆流淤滞,胆汁成份改变有关.近来对胰胆管合流异常的研究发现,长期胰液胆道返流可刺激胆管壁和改变胆汁成分,导致胆管扩张或结石形成[1].原发性胆道结石病例都有不同程度的胆管扩张和胆汁病理性外观变化,其胆道内是否有胰液返流尚不清楚.本文旨在探讨原发性胆道结石病人胆道内有关胰液返流的临床证据及其与胰胆管合流异常的关系. 相似文献

胰胆管合流异常 (pancreaticobiliary maljunction,PBM)是胰管和胆总管异常汇合的一种先天性畸形 [1 ]。从 1916年 Kizu-mi首先提出 PBM这一概念 ,至 1978年日本学者因此成立“胰胆管合流异常研究会”,PBM已日渐引起国内外广泛关注 ,对PBM基础及临床的研究正逐步深入。1 PBM的病理特征约 75 %的正常人胆总管与主胰管在十二指肠粘膜下汇合成共通管 ,并随着年龄逐渐增长。共通管周围及近端具有 Oddi氏括约肌 ,其中胆总管括约肌部分恒定存在 ,在神经与体液双重因素的调节下可控制胆汁的正常排出 ,亦可防止胰液逆流入胆管。据 1991年日… 相似文献

近年来,随着磁共振胰胆管成像( magnetic resonance cholangiography,MRCP) 和内镜逆行性胆管胰管造影术( endoscopic retrograde cholangiopancreatography, ERCP)等影像学检查的广泛应用,胰胆管合流异常(pancreaticobiliary realjunction,PBM)病例的检出率有较大幅度提高,PBM与胆胰部疾病的相关性也越来越引起重视。胰胆管合流异常的概念首先由Kozumi和Kodama于1916年提出,他们是从先天性胆管囊肿的病例中发现胰胆管汇合的异常。直到1969年,Babbitt等从病因学方面报道了PBM与先天性胆总管囊肿的相关性后,PBM才开始作为一个独立的疾病诊断,无论其是否合并有胆管囊肿。随后的研究也表明,PBM不仅与先天性胆总管囊肿有关,还与胆道结石、胆囊炎、急慢性胰腺炎等多种疾病的发生相关。最近许多研究者发现PBM与胆胰部恶性肿瘤的发生有着密切的关系[2,3],这为研究胆胰肿瘤发生的机制提供了新的思路,现综述如下。 相似文献

Anomalous pancreaticobiliary junction with cystic dilatation of the biliary tract is usually associated with carcinoma arising from the cyst wall. We report an extracystic location of biliary carcinoma in the presence of anomalous pancreaticobiliary junction and cysts in a patient with obstruction of the origin of the left hepatic duct who underwent hepatobiliary resection. Cholangiocarcinoma was found to have arisen in a noncystic left hepatic duct, in conjunction with cystic dilatation involving both the cystic and common bile ducts. The present case supports a relationship between anomalous pancreaticobiliary junction and biliary carcinogenesis that may affect the extracystic biliary tree. 相似文献

Background Anomalous pancreaticobiliary junction (APBJ) is associated with pancreaticobiliary cancer. Limited data are available on endoscopic
biliary drainage for unresectable malignant biliary obstruction with APBJ. This study evaluated the efficacy and safety of
self-expandable metallic stents (EMSs) for the management of malignant biliary obstruction with APBJ.
Methods Between 1993 and 2005, 324 patients with unresectable malignant biliary obstruction underwent insertion of an EMS. Six of
these patients with concomitant APBJ constituted the subjects of this study. Early (≤30 days after EMS insertion) and late
(>30 days after EMS insertion) stent-related complications and stent patency were evaluated in these six patients.
Results The cause of biliary obstruction was gallbladder cancer in four patients and pancreatic cancer in two patients. Uncovered
EMSs were inserted across the common channel without performance of a biliary sphincterotomy. The diameter of the uncovered
EMS used was based on the diameter of the common channel. For all six patients, endoscopic biliary drainage was successful,
and their jaundice subsided steadily. None of the six patients experienced early complications, including acute pancreatitis.
The mean stent-related complication-free period was 163 days. Stent occlusion caused by tumor ingrowth occurred in two patients.
Acute cholangitis and cholecystitis were observed in one patient each.
Conclusions Uncovered EMSs are effective for palliation of unresectable malignant biliary obstruction in patients who have APBJ without
increasing the risk of stent-related early complications. 相似文献

Between 1978 and 1988, 15 patients with gallbladder cancer and 2 patients with bile duct cancer were seen among 49 patients
with anomalous union of the pancreaticobiliary ductal system. Radiographic findings revealed two types of this anomalous condition:
one in which the pancreatic duct entered the common bile duct(type 1) and one in which the common bile duct entered the pancreatic
duct (type 2). In gallbladder cancer, the common bile duct presented no dilatation, or in some patients, mild dilatation,
and type-1 anomalous union was frequently found among these patients. In contrast, the two patients with bile duct cancer
had cystic dilatation of the common bile duct and type-2 anomalous union. The bile amylase level, which was determined in
seven patients, was extremely high in all the patients. Histopathologically, the tumors in most patients showed papillary
to papillo-tubular proliferation in the mucosal layer while atypical epithelial hyperplasia was noted in the vicinity of the
tumor area. These findings suggest that this congenital anomaly in both ducts results in a loss of the normal sphincteric
mechanism of the doudenal papilla, and that chronic relapsing cholecystitis or cholangitis, caused by the reflux of pancreatic
juice into the biliary tract, can induced progressive changes to atypical epithelial hyperplasia which may develop into carcinoma. 相似文献

The role of endoscopic retrograde cholangiopancreatography (ERCP) in the preoperative assessment of anomalous pancreaticobiliary
junction was retrospectively evaluated in 74 consecutive patients (19 males and 55 females; aged 0–80 years). Sixty-three
patients had congenital biliary dilatation and 11 did not. Type classification of congenital biliary dilatation was possible
by ERCP alone in 45 patients (71%). The main causes of classification failure were previous bilio-enteric anastomosis and
restriction of postural changes during ERCP due to general anesthesia in pediatric patients. Classification of anomalous junction
was possible in 69 patients (93%). Technical difficulty in ERCP caused classification failure in 5 patients. Neoplastic lesions
were found in 12 patients (16%) and all but 1 were correctly diagnosed by ERCP. We conclude that ERCP plays an important role
in the preoperative diagnosis and type classification of anomalous pancreaticobiliary junction and congenital biliary dilatation. 相似文献

We present a case of carcinoma in adenoma of the gallbladder with anomalous pancreaticobiliary ductal junction (APBDJ) in
a 60-year-old Japanese woman. The patient had no abdominal symptoms. Serum levels of carcinoembryonic antigen, carbohydrate
antigen 19-9, elastase 1, and α-fetoprotein were all within normal limits. Ultrasonography demonstrated two irregular hyperechoic
lesions of the gallbladder. Computed tomography showed two soft-tissue density masses in the gallbladder. Endoscopic retrograde
cholangiopancreatography showed APBDJ and two protruding lesions in the gallbladder. Angiography displayed a hypervascular
lesion fed by the cystic artery. The patient underwent total cholecystectomy; the diagnosis of the intraoperative frozen section
was well differentiated adenocarcinoma with possible mucosal invasion. Amylase level in the gallbladder bile was 90600 IU/l.
Macroscopically, there were two polyps in the gallbladder. The larger one, 3.5 cm in diameter, was adenocarcinoma in adenoma,
and the smaller one, an inflammatory polyp. We briefly discuss the relationship among adenoma, adenocarcinoma of the gallbladder,
and APBDJ. 相似文献
