Kudo’s pit pattern classification is an accurate diagnostic method for the differentiation of neoplastic and non-neoplastic colorectal lesions. Publication bias is significant in the current available literature.

2020年11月4日 · Used extensively in the East, the Kudo pit pattern classification system has been adopted in the Western world as well. 17–20 It requires magnification colonoscopy with dye spray (although many Western endoscopists use it without dye spray), and allows for evaluation of malignant polyps through characterization of the pits, which are openings ...

The Kudo pit pattern , with the use of dye chromoendoscopy, has been found to be highly accurate for predicting superficial (Type VI) and deep submucosal invasion (Type VN). 12 However, assessing the Kudo pit pattern has limited use owing to dye availability, additional procedural time for their preparation and application and complexity of ...

Background Cold snare polypectomy (CSP) is recommended for the resection of small colorectal polyps. However, few studies have investigated the efficacy of cold endoscopic mucosal resection...

The Kudo pit pattern can be assessed on colonoscopy and predicts the presence or absence of neoplasia and malignancy. [1] It is as follows: [2] Notes: A modified version includes a Type II-O pattern that is highly specific for SSAs. [3] Gastrointestinal polyps. Adenomatous polyps. Colorectal adenocarcinoma.

The number of patients, polyps and diagnostic performance of Kudo's pit pattern classification were retrieved from suitable studies. Pooled sensitivities and specificities were calculated using fixed or random effect models according to their heterogeneity.

Core tip: According to the current available evidence, Kudo’s pit pattern classification is an accurate diagnos-tic method for the differentiation of neoplastic and non-neoplastic colorectal lesions. The risk of potential publi-cation bias should be noted. Li M, Ali SM, Umm-a-OmarahGilani S, Liu J, Li YQ, Zuo XL.

Kudo pit pattern: Kudo and colleagues first highlighted the feasibility of examining and classifying pit patterns to distinguish type of polyps by using magnifying endoscopy. This scheme broadly categorizes pit patterns into 7 types based on the pit appearance and structure (Figure 3 ).

Kudo and colleagues classified pit patterns into 7 types to enable the differentiation of neoplasms as well as allow for histologic grading and depth evaluation of early cancers. 6 Type I includes round pits that are observed in normal mucosa. Type II includes stellate or papillary pits, which indicate hyperplasia.

The Kudo classification classifies pit pattern as round / normal (Type I), asteroid (Type II), tubular or round pit smaller than normal pit (Type IIIS), tubular or round pit larger than normal pit (Type IIIL), gyrus/dendritic (IV), irregular arrangement (VI), and loss of …
