血清淀粉酶同工酶谱诊断胰胆管连接异常的初步临床应用

目的 通过血清淀粉酶同工酶谱检测诊断伴有胆管轻度扩张的胰胆管连接异常。方法 采仪式 8例胆管轻度扩张并经术中造影证实PBM的患儿术前、术后血清,另取8例正常儿童血清作对照,应用不连续缓冲系统苤膜电泳法行酶谱分析。结果 政党组仅存在P1和P2,PBM患儿术前血清淀粉酶同工酶波峰除有P1和P2外,还出现P3,P4、P5等异常波峰,无优势波峰,该血清酶学异常在胰胆分流术后基本消失,结论 PBM患儿即使仅伴有胆管轻度扩张。其血清淀粉酶同工酶谱仍存在异常,具一定特异性,有助于PBM的临床诊断。

Pancreatic disorders associated with anomalous pancreaticobiliary junction.

BACKGROUND: The aim of this study was to establish an optimal management strategy for pancreatic disorders associated with anomalous pancreaticobiliary junction (APBJ). METHODS: In 64 adult surgical cases of APBJ (common channel 15 mm or longer) (43 with and 21 without choledochal cyst), associated pancreatic disorders, pancreatographic results, and treatment outcomes were analyzed. RESULTS: Of 64 patients, 56 had pancreatobiliary symptoms. Twenty-four patients (38%) had pancreatic disorders: acute pancreatitis (n = 20), chronic calcifying pancreatitis (n = 2), and pancreatic carcinoma (n = 2). Twenty patients (31%) had abnormal pancreatograms. The incidence of acute pancreatitis was significantly higher in patients with an abnormal pancreatogram, particularly dilatation, protein plugs or stones of the common channel or main pancreatic duct, and coexisting pancreatic ductal anomaly. All patients with choledochal cyst underwent cyst excision and hepaticojejunostomy. Eleven patients without choledochal cyst or pancreatobiliary carcinoma underwent cholecystectomy alone. Protein plugs and pancreatic stones were extracted through the bile duct stump or by sphincterotomy. No patients experienced pancreatitis during a mean postoperative follow-up of 6.7 years. CONCLUSIONS: In managing APBJ, attention should be paid to the possibility of associated pancreatic disorders and an abnormal pancreatogram. APBJ with choledochal cyst requires cyst excision. Cholecystectomy alone may be adequate for APBJ without cyst.     

胰胆管合流异常与胰胆管疾病的关系

自Babbitt[1]1969年首次报道胰胆管合流异常(anomalouspancreaticobiliary ductal uion,APBDU)以来,人们发现APBDU与许多胆道及胰腺疾病密切相关。近年来,随着MRCP、ER-CP、PTC等影像学技术的发展和广泛应用,有关的报道逐渐增多[2],对APBDU又有了更进一步的认识。APBDU的基本概念解剖学上APBDU是指胰胆管共同通道在十二指肠壁外合流,造成共同通道过长,使十二指肠乳头括约肌的作用不能影响到整个合流部,胆汁、胰液相互逆流而引起胆道及胰腺的各种疾病。APBDU分为两型:①P-C型,即胰管注入胆总管型;②C-P型,即胆总管注入胰…     

Extracystic biliary carcinoma associated with anomalous pancreaticobiliary junction and cysts

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.     

Type classification of anomalous pancreaticobiliary junction by ERCP

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.

Self-expandable metallic stents for malignant biliary obstruction with an anomalous pancreaticobiliary junction

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.
