LSTs are always larger than 2 cm (!) and are called “LST of granular-type” or “LST of non-granular type”. The group of “LST-granular homogenous” are the most common among these. Despite their sometimes considerable size, they almost always bear a …

2014年8月11日 · Colorectal laterally spreading tumors (LSTs), which are classified into granular (LST-G) and nongranular (LST-NG) types, are a good indication for endoscopic treatment. In practice, the nongranular type is more difficult to remove endoscopically than the granular type.

Most colorectal tumors larger than 20 mm in diameter are called laterally spreading tumors (LST), most of which are adenomatous lesions. Laterally spreading tumors are classified into two types according to their morphology, granular type (LST-G) and non-granular type (LST-NG).

Laterally spreading tumors (LSTs) are originally classified into 4 subtypes. Pseudo-depressed nongranular types (LSTs-NG-PD) are gaining attention because of their high malignancy potential.

In the Paris consensus of 2002, LST were defined as nonpolypoid lesions larger than 10 mm in width that typically extend laterally and circumferentially along the colonic wall, rather than vertically and were classified as type 0-IIa 3. LST are distinguished based on their granular or nongranular, homogenous or nonhomogenous appearance 1. These ...

LSTs are divided into the granular (LST-G) and non-granular type (LST-NG) based on their detailed endoscopic appearance during chromoendoscopy with indigo carmine dye spraying[13,17].

By definition laterally spreading tumors (LSTs) are superficial tumors that spread laterally along the colon wall with ≥10 mm diameter. 1 There are two main types of LSTs: Granular (G-LST) and flat (F-LST) types. 2 G-LST was subclassified into homogeneous and mixed nodular subtypes.

2013年8月11日 · Laterally spreading tumors (LSTs) are characterized by lateral and circumferential extension along the colorectal wall, rather than vertical extension, and form flat, broad-based lesions [1 – 3]. LSTs are defined as flat, …

2018年10月10日 · Colorectal laterally spreading tumors (LSTs) are superficial and flat neoplasm that are larger than 10 mm in diameter; LSTs have a short axis that extends laterally along the colorectal luminal wall. LSTs are divided into 2 types: the granular and the nongranular type.
