Description

Enteroscopy quality standard and scoring system based on image recognition

Technical Field

The invention relates to the technical field of image recognition and intelligent medical treatment, in particular to an enteroscopy quality standard and scoring system based on image recognition.

Background

In China, the incidence rate of colorectal cancer (CRC) is 3 to 5 of malignant tumors, and the mortality rate of the CRC is 5 of the mortality rate of the malignant tumors. The colorectal adenoma is the most main precancerous lesion of the CRC, and is an effective measure for preventing the CRC by timely screening, finding and performing endoscopic resection.

Colonoscopy, which is of lower quality, results in a double increase in the incidence of colorectal adenoma leak (AMR) and interphase cancer. At present, colonoscopy has uneven quality, and the Adenoma Detection Rate (ADR) of different screening populations has larger difference which is 20-47 percent; adenomas ADR of different endoscopists are also greatly different, ranging from 21% to 86%.

At present, a quality control system of colonoscopy mainly evaluates and requires the quality of the total colonoscopy in the past period of time, but quantitative evaluation is difficult to carry out on each examination in actual clinical work, a quantitative scoring method is lack for carrying out individual scoring on the colonoscopy at present, and the quality of each examination cannot be compared at the same time.

Colonoscopy, while relatively safe, still presents a certain risk and pain, especially for some special patients, such as patients with abdominal obesity, emaciation, and history of abdominal surgery, the risk and pain of perforation increase accordingly. Deciding on colonoscopy is clearly a major psychological, economic and time challenge for the patient. Therefore, it is desirable for digestive physicians and endoscopists to optimize the quality of a colon examination for the maximum benefit to the patient. It follows that the importance of the colonoscope quality control task goes undoubtedly.

Disclosure of Invention

The invention aims to overcome the defects of the technology and provide an enteroscopy quality standard and a scoring system based on image recognition.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a enteroscopy quality standard and system of scoring based on image recognition which characterized in that: comprises a midgut microscope examination quality standard and a scoring system;

the midgut endoscope examination quality standard evaluation table comprises the number of suspicious segments found in the whole endoscope withdrawal process, total examination time, endoscope withdrawal time, effective endoscope withdrawal time, total screenshot number, whether the retrocecal part is reached or not, whether rectum inversion operation is carried out or not, an examination integrity index, examination definition and a safety index; the number of suspicious intestinal sections found in the whole endoscope withdrawing process is the number of intestinal sections with pathological changes found in the endoscope withdrawing process; the total examination time is the time from the beginning of the enteroscopy to the end of the examination, and the entrance and exit of the enteroscopy equipment are taken as the standard; the endoscope withdrawing time is the time when the enteroscope equipment reaches the appendix opening and is withdrawn to the outside of the anus; the effective lens withdrawing time is the movement and checking time for excluding the invalid value static time in the lens withdrawing process; whether the image reaches the ileocecal part or not and whether the rectum reversal is carried out or not are determined according to whether relevant images are intercepted or not; the examination integrity index is whether the observation of the intestinal tract is complete or not in the process of the endoscope withdrawal examination; the checking definition refers to the definition of a glasses-removed video image; the scoring system scores each item of content of the enteroscopy quality standard evaluation table according to the standard, and finally calculates the total score of the examination and generates a corresponding report.

The invention has the advantages that the invention can provide a quality standard for enteroscopy to quantitatively evaluate each examination in a lifetime, and can also individually score each examination of each doctor according to the provided quality standard for enteroscopy. Therefore, the doctor can take more careful treatment on the enteroscopy, the doctor can find the self deficiency and continuously improve the operation technique, and the doctor can feel more relieved and has great economic and social benefits.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a scoring schematic of the present invention.

Detailed Description

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1 and fig. 2, an enteroscopy quality standard and scoring system based on image recognition is characterized in that: comprises a midgut microscope examination quality standard and a scoring system;

The scoring system scores each quality standard and calculates a final weighted score;

the scoring system score is 0-120, and the final total score is calculated by adopting weighting to judge the quality of each check of the doctor; the scoring system comprises: six variables of A integrity index, B total endoscope withdrawing time, C definition, D effective endoscope withdrawing time, whether E reaches the ileocecal part and whether F carries out rectum inversion;

the calculation mode of each variable value is as follows:

the variable a is the rotating lens circumference 4 when the lens is withdrawn, the maximum value is 100, and note: the full score is 100 in 25 weeks, and the full score is 100 when the full score is more than or equal to the full score;

the variable B is total time to recede (sec)/4.5, the maximum value is 100, note: the score is full in 7 minutes and 30 seconds, the score is deducted as short as the value, and the score is full when the score is larger than the value;

the variable C ═ clarity (%). 100, max 100;

the variable D is the effective lens withdrawing time (second)/3.6, the maximum value is 100, and note: dividing into full points 6, deducting points shorter than the value, and dividing into full points if the value is larger than the value;

and the variable E is 10, the blind part screenshot is detected, the variable E is 0, and the detection does not reach the blind part.

And the variable F is 10, the rectum reversal operation is detected, the variable F is 0, and the rectum reversal operation is not detected.

The six variables are respectively distributed with corresponding weights according to the importance degrees, the weights of A, B, C, D are respectively 40%, 10%, 20% and 30%, the variable E, F is independently calculated according to the operation, if the operation is carried out, 10 points are added, and if the operation is not carried out, 0 point is added; the total score calculation mode can be obtained according to the mode: total ═ a × 40% + B × 10% + C × 20% + D × 30% + E + F.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
