Problems solved by technology

[0004] (1) The interference of surgical operations on time cannot be ruled out; if the doctor increases surgical procedures, the time to withdraw the mirror must be prolonged
but not associated with adenoma detection
[0005] (2) The effect of the doctor’s operation of cleaning the intestinal contents on the withdrawal time of the mirror. If the intestinal preparation is not good, the doctor needs to spend time flushing the intestinal tract, and the time at this time is calculated within the withdrawal time, which cannot improve the detection of adenoma
[0006] (3) The fuzzy picture caused by irregular mirror movement is meaningless to improve the detection of adenoma

Embodiment 1

[0054] Embodiments of the present invention provide a method for evaluating the effective withdrawal time of colonoscopy, such as figure 1 As shown, the effective withdrawal time evaluation method of the colonoscopy includes:

[0055] S101, performing frame-by-frame recognition on the video of colonoscopy withdrawal inspection, and identifying whether each video frame can be used to find lesions; lesions include gastrointestinal diseases, gastrointestinal tumors, etc., such as polyps;

[0056] S102. According to the frame-by-frame identification, determine the number of video frames that cannot be used to find lesions in the video of the colonoscopy retraction examination;

[0057] S103. Determine the invalid mirror-retirement duration according to the number of video frames;

[0058] S104, in the video of the colonoscope retraction inspection, determine the retraction time from the ileocecal or terminal ileum to the dentate line of the anus;

[0059] S105. Determine an effect...

Embodiment 2

[0101] An embodiment of the present invention provides a device for evaluating the effective withdrawal time of the colonoscopy examination. The evaluation device for the effective withdrawal time of the colonoscopy examination includes: a memory, a processor, and a device stored on the memory and can be used on the processor. computer programs running on it;

[0102] When the computer program is executed by the processor, the steps of the method for evaluating the effective withdrawal time of colonoscopy according to any one of the first embodiment are realized.

Embodiment 3

[0104] An embodiment of the present invention provides a computer-readable storage medium, the computer-readable storage medium stores an evaluation program for the effective withdrawal time of the colonoscopy examination, and the evaluation program for the effective withdrawal time of the colonoscopy examination is executed by a processor , realize the steps of the method for evaluating the effective withdrawal time of colonoscopy as described in any one of the first embodiment. The storage may be cloud storage.

[0105] For the specific implementation of Embodiment 2 and Embodiment 3, reference may be made to Embodiment 1, which have corresponding technical effects.

Abstract

The invention relates to an effective mirror retreating time evaluation method and device for enteroscopy and a storage medium. The effective retreating time evaluation method for enteroscopy comprises the following steps: performing frame-by-frame identification on an enteroscopy retreating video, and identifying whether each video frame can be used for finding a lesion or not; according to the frame-by-frame identification, determining the number of video frames which cannot be used for searching lesions in the enteroscopy retroscopy video; according to the number of the video frames, determining an invalid mirror retreating time length; in the enteroscope retreating examination video, determining the retreating time from the ileocecal part or the ileum tail end to the anal tooth-shaped line; and according to the mirror retreating time and the invalid mirror retreating duration, determining the effective mirror retreating time of enteroscopy. According to the application, the quality of colonoscopy can be evaluated more effectively, and the detection rate of digestive tract diseases and digestive tract tumors can be improved in an auxiliary manner.

Description

technical field [0001] The present application relates to the field of medical technology, in particular to a method, device and storage medium for evaluating the effective withdrawal time of colonoscopy. Background technique [0002] Colon cancer is a malignant tumor with high morbidity and mortality of digestive tract tumors. Early detection and treatment are important ways to improve the survival rate of cancer patients and improve the quality of life of patients after surgery. Early diagnosis of gastrointestinal diseases and gastrointestinal tumors can be achieved through direct observation of the digestive tract through colonoscopy and auxiliary imaging methods. However, colonoscopy is not completely correct. Studies have shown that the missed diagnosis rate of colonoscopy polyps is about 25%. The quality of colonoscopy is affected by many factors, among which the following are the common basic factors affecting colonoscopy: (1) Physician's experience and professional ...
