2024年7月1日 · In terms of imaging appearance, they can be categorized as: duct-ectatic, non-duct-ectatic, cystic, and intermediate. Briefly, the duct-ectatic type is the most typical form of IPNB, characterized by the presence of papillary projections within a fusiform or diffusely dilated duct, reflecting excess mucin production.

Intracholecystic papillary neoplasm (ICPN) of the gallbladder is a relatively new concept and is suspected to share clinicopathologic features with intraductal papillary mucinous neoplasm (IPMN) of the pancreas and intraductal papillary neoplasm of the bile duct (IPNB).

USG and CT are the first choices of imaging in the diagnosis of EC, with the specificity of USG in the range of 90%. CT is helpful for confirming the diagnosis and can reveal calcified cystic walls, daughter cysts, and exogenous cysts, as well as evaluating the cyst volume and density.

Ultrasonography (USG) of the abdomen showed a well-defined multiloculated cyst in segment IV of the liver, which was further confirmed by a Contrast-enhanced Computed Tomography (CECT) scan. The patient underwent laparoscopic surgery based on …

2017年9月1日 · Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors characterized by papillary growth within the bile duct lumen...

Ultrasonography (USG) will help in confirming biliary duct dilation, identifying the site of obstruction and also ruling out gallstones. Multidetector computed tomography (MDCT) is commonly used for diagnosis and staging purposes due to wider availability.

Introduction: Intraductal papillary neoplasm of bile duct (IPNB) are premalignant lesions that can progress to invasive carcinoma, classified into four morphological subtypes: intestinal, pancreatobiliary, gastric, and oncocytic. Recent studies also introduce a classification into type 1 and type 2 based on architectural and cellular ...

a、 内网用户，访问网通的IP走网通链路，默认走电信链路，达到访问速度快和链路带宽的合理化利用，并且当其中一条链路down掉时，所有流量可以切换到另外一条链路。 …… ①、请按照上述需求补充其它主要的具体配置，包括路由、nat等配置（假定内网上外网nat以接口ip进行转换）？ ②、如何实现双出口nat server情况下，使得外网用户可以通过网通IP和电信IP访问内部服务器？ （该方案需要保证外网用户数据包从哪条链路进来就从哪条链路回包，否则对于路由不对称的 …

2024年12月2日 · Portal hypertension is defined as a hepatic venous pressure gradient (HVPG) >5 mmHg, which is a surrogate for the portosystemic pressure gradient. Clinically significant portal hypertension is defined as a gradient >10 mmHg, and variceal bleeding may occur at a gradient >12 mmHg. Causes can be split by their relation to the hepatic sinusoids 7:

IPNB dzieli się na typ 1 podobny do IPMN i typ 2 niepodobny do IPMN. Rokowanie w przypadku IPNB jest lepsze niż w typowym raku dróg żółciowych. Cholangioskopia jest przydatna w ustaleniu rozpoznania, zarówno w określeniu umiejscowienia, jak i zaawansowania.
