[0035] According to the low rectal anastomosis artificial anal canal and anal canal status information monitoring method of the embodiments of the present invention, the status of the artificial anal canal can be monitored according to the condition of the drainage fluid and the stoma, and the monitoring score of the artificial anal canal status can be determined. The status of the natural anal canal can be evaluated according to the subjective feelings of the patient, the CT images of the anastomosis, and laboratory data, and the monitoring score of the anal canal status can be determined. Further, according to the monitoring score of the artificial anal canal status and the monitoring score of the anal canal status, a monitoring report is generated, improving the comprehensiveness and accuracy of the monitoring of the low rectal anastomosis artificial anal canal and anal canal status information.

[0036] According to an embodiment of the present invention, in step S101, patient data is acquired, wherein the patient data includes: patient subjective data, patient personal information, and patient health data.

[0037] For example, patient subjective data is acquired, such as asking the patient whether there are symptoms such as pain, patient personal information is acquired, such as name, age, and gender, and patient health data is acquired, such as performing routine item examinations such as blood glucose on the patient.

[0038] According to an embodiment of the present invention, in step S102, artificial anal canal-related data is acquired, wherein the artificial anal canal-related data includes: drainage fluid data and stoma data.

[0039] For example, the relevant data of the artificial anal canal implanted in the patient is recorded, such as drainage fluid data and stoma data.

[0040] According to an embodiment of the present invention, in step S103, according to the patient data and the artificial anal canal-related data, the monitoring score of the artificial anal canal status is determined.

[0041] According to an embodiment of the present invention, step S103 includes:

[0042] According to the stoma data, a stoma image is determined;

[0043] According to the drainage fluid data, the drainage fluid volume and the drainage fluid image are determined;

[0044] According to the drainage fluid image and the stoma image, a stoma patency recognition result, a stoma skin recognition result, a color recognition result, and a character recognition result are determined;

[0045] According to the patient personal information, the patient's recovery environmental temperature, the patient's food intake, the patient's activity level, the patient's age, the patient's gender, and the patient's surgery time are determined;

[0046] According to the patient's surgery time, the patient's recovery stage is determined;

[0047] According to the patient's recovery stage, the patient's recovery stage vector is determined;

[0048] Determine the albumin content and blood glucose content of the patient based on the patient's health data;

[0049] Determine similar historical patients based on the patient's age and gender;

[0050] Obtain the historical drainage volume, historical patient food intake, historical patient recovery environmental temperature, historical patient activity level, historical patient albumin content, and historical patient blood glucose content of the similar historical patients;

[0051] Determine the drainage volume relationship function based on the historical drainage volume, historical patient food intake, historical patient activity level, historical patient recovery environmental temperature, historical patient albumin content, and historical patient blood glucose content;

[0052] Determine the standard drainage volume based on the drainage volume relationship function, the patient's food intake, the patient's activity level, the patient's albumin content, and the patient's blood glucose content;

[0053] Determine the artificial anal canal status monitoring score based on the drainage volume, the standard drainage volume, the patient's recovery stage vector, the stoma patency recognition result, the stoma skin recognition result, the color recognition result, and the character recognition result.

[0054] For example, an image of the stoma area is collected by a camera; the amount of drainage fluid discharged (drainage fluid volume) is obtained, and an image of the discharged drainage fluid (drainage fluid image) is collected; based on the drainage fluid image, the color and properties of the drainage fluid are identified and judged to determine the color recognition result and property recognition result. Based on the stoma image, the patency of the stoma and the condition of the skin around the stoma are judged to determine the stoma patency recognition result and stoma skin recognition result; according to the patient's personal information, the patient's recovery environmental temperature is determined (for example, the temperature of the patient's ward is 26 degrees Celsius), the patient's food intake, the patient's activity level (for example, the patient's activity level determined according to the number of steps recorded by a sports software), the patient's age, the patient's gender, and the patient's surgery time (for example, the date of the patient's surgery is January 1st); according to the patient's surgery time, the patient's recovery stage is determined. For example, if the date of the patient's surgery is January 1st and the current date is January 2nd (within 72 hours after surgery), then the patient's recovery stage is the early postoperative stage. If the current date is January 5th (3 - 14 days after surgery), then the patient's recovery stage is the postoperative recovery stage. If the current date is February 1st, then the patient's recovery stage is the long - term follow - up stage; according to the patient's recovery stage, the patient's recovery stage vector is determined. For example, when the patient's recovery stage is the early postoperative stage, the patient's recovery stage vector is (1, 0, 0). When the patient's recovery stage is the postoperative recovery stage, the patient's recovery stage vector is (0, 1, 0). When the patient's recovery stage is the long - term follow - up stage, the patient's recovery stage vector is (0, 0, 1); a routine examination is performed on the patient to obtain the patient's albumin content and blood glucose content; according to the patient's age and gender, similar historical patients are determined. For example, if the patient's age is 60 years old and the patient's gender is male, then patients aged 58 - 62 years old and male are determined as similar historical patients; the historical drainage fluid volume, historical patient food intake, historical patient recovery environmental temperature, historical patient activity level, historical patient albumin content, and historical patient blood glucose content of similar historical patients with normal recovery status during the long - term follow - up stage after surgery are obtained; the drainage fluid volume is related to the patient's food intake, patient recovery environmental temperature, patient activity level, patient albumin content, and patient blood glucose content to a certain extent. For example, when the patient eats more, the drainage fluid volume is also more. Based on the correlation of the above data, a drainage fluid volume relationship function is determined; the patient's food intake, patient activity level, patient albumin content, and patient blood glucose content are substituted into the drainage fluid volume relationship function to determine the normal drainage fluid volume of the patient during the long - term follow - up stage, that is, the standard drainage fluid volume; based on the drainage fluid volume, standard drainage fluid volume, patient recovery stage vector, stoma patency recognition result, stoma skin recognition result, color recognition result, and property recognition result, the status of the patient's artificial anal canal is evaluated to determine the artificial anal canal status monitoring score.

[0055] According to an embodiment of the present invention, based on the drainage fluid image and the stoma image, determining the stoma patency recognition result, the stoma skin recognition result, the color recognition result, and the character recognition result includes:

[0056] In the drainage fluid image, identifying whether there is an abnormality in the color of the drainage fluid through an image detection model to determine the color recognition result;

[0057] In the drainage fluid image, identifying whether there is an abnormality in the character of the drainage fluid through an image detection model to determine the character recognition result;

[0058] In the stoma image, identifying whether the stoma is patent through an image detection model to determine the stoma patency recognition result;

[0059] In the stoma image, identifying whether there is an abnormality in the skin around the stoma through an image detection model to determine the stoma skin recognition result.

[0060] For example, the image detection model belongs to a type of deep learning model. The image detection model is trained with historical data so that the image detection model can identify the color of the drainage fluid, the character of the drainage fluid, the patency of the stoma, and the condition of the skin around the stoma in the image. In the drainage fluid image, identifying whether there is an abnormality in the color of the drainage fluid through the image detection model to determine the color recognition result. When the color of the drainage fluid is yellow or light green, there is no abnormality in the color of the drainage fluid, and the color recognition result is 1. When the color of the drainage fluid is bloody, it may indicate anastomotic bleeding or intestinal injury, so there is an abnormality in the color of the drainage fluid, and the color recognition result is 0. In the drainage fluid image, identifying whether there is an abnormality in the character of the drainage fluid through the image detection model to determine the character recognition result. When the character of the drainage fluid is normal liquid, there is no abnormality in the character of the drainage fluid, and the character recognition result is 1. When the character of the drainage fluid is pus or mucus, it may indicate anastomotic fistula or abdominal infection, so there is an abnormality in the character of the drainage fluid, and the character recognition result is 0. In the stoma image, identifying whether the stoma is patent through the image detection model to determine the stoma patency recognition result. If the stoma is patent and there is no blockage, retraction, or prolapse, the stoma patency recognition result is 1. If the stoma is not patent, the stoma patency recognition result is 0. In the stoma image, identifying whether there is an abnormality in the skin around the stoma through the image detection model to determine the stoma skin recognition result. If there is no redness, exudation, or ulceration in the skin around the stoma, the stoma skin recognition result is 1. If there is redness, exudation, or ulceration in the skin around the stoma, the stoma skin recognition result is 0.

[0061] According to an embodiment of the present invention, determining a drainage volume relationship function based on the historical drainage volume, the historical patient food intake, the historical patient activity level, the historical patient recovery environmental temperature, the historical patient albumin content, and the historical patient blood glucose content includes: determining a first undetermined coefficient equation of the drainage volume relationship function according to formula (1),

[0062] (1),

[0063] wherein, the subscript h in each parameter indicates that the parameter is historical data, is the historical drainage volume of the k-th similar historical patient on the i-th historical date, is the historical patient food intake of the k-th similar historical patient on the i-th historical date, is the historical patient activity level of the k-th similar historical patient on the i-th historical date, is the historical patient albumin content of the k-th similar historical patient on the i-th historical date, is the historical patient recovery environmental temperature of the k-th similar historical patient on the i-th historical date, is the historical patient blood glucose content of the k-th similar historical patient on the i-th historical date, , , , , , , , , and are the first undetermined coefficients of the first undetermined coefficient equation;

[0064] Solving the first undetermined coefficient according to the historical drainage volume, the historical patient food intake, the historical patient activity level, the historical patient recovery environmental temperature, the historical patient albumin content, and the historical patient blood glucose content to obtain the solution value of the first undetermined coefficient;

[0065] Determining the drainage volume relationship function according to the solution value of the first undetermined coefficient and the first undetermined coefficient equation.

[0066] According to an embodiment of the present invention, indicating that the historical drainage volume of the k-th similar historical patient on the i-th historical date has a positive correlation with the historical patient food intake of the k-th similar historical patient on the i-th historical date. For example, excessive food intake stimulates the secretion of bile and pancreatic juice, increases the intestinal fluid volume, and may lead to an increase in the drainage volume, It indicates that there is a positive correlation between the historical drainage volume of the k-th similar historical patient on the i-th historical date and the historical patient activity volume of the k-th similar historical patient on the i-th historical date. For example, when the activity volume is relatively large, the secretions flow to the lower position under the action of gravity, resulting in an increase in the drainage volume. It indicates that there is a positive correlation between the historical drainage volume of the k-th similar historical patient on the i-th historical date and the historical blood glucose content of the k-th similar historical patient on the i-th historical date. For example, the higher the blood glucose, the easier it is to induce anastomotic infection, increase the exudation volume, and lead to an increase in the drainage volume. It indicates that there is a negative correlation between the historical drainage volume of the k-th similar historical patient on the i-th historical date and the historical albumin content of the k-th similar historical patient on the i-th historical date. For example, the lower the albumin content, the lower the plasma colloid osmotic pressure, the increase in interstitial fluid exudation, and the increase in the drainage volume. It indicates that there is a negative correlation between the historical drainage volume of the k-th similar historical patient on the i-th historical date and the historical environmental temperature for the k-th similar historical patient's recovery on the i-th historical date. For example, the lower the environmental temperature, it may stimulate intestinal contraction, increase the discharge of secretions, and lead to an increase in the drainage volume. Based on the above relationships, the first undetermined coefficient equation of the drainage volume relationship function can be obtained.

[0067] According to an embodiment of the present invention, fitting can be performed based on multiple parameters involved in the above first undetermined coefficients, that is, fitting is performed based on the historical drainage volume, historical patient food intake, historical patient activity volume, historical environmental temperature for the historical patient's recovery, historical albumin content of the historical patient, and historical blood glucose content of the historical patient, and the above multiple first undetermined coefficients are solved. There are 10 first undetermined coefficients, namely, 、 、 、 、 、 、 、 、 and , the above 10 first undetermined coefficients are solved according to the historical drainage volume, historical patient food intake, historical patient activity volume, historical environmental temperature for the historical patient's recovery, historical albumin content of the historical patient, and historical blood glucose content of at least 10 similar historical patients, the solution values of the above 10 first undetermined coefficients are obtained, and the solution values of the above 10 first undetermined coefficients are substituted into the first undetermined coefficient equation to determine the drainage volume relationship function.

[0068] In this way, based on the historical drainage volume, historical patient food intake, historical patient activity level, historical patient recovery ambient temperature, historical patient albumin content, and historical patient blood glucose content, a drainage volume relationship function can be determined, which accurately describes the relationship among the patient's food intake, patient activity level, patient recovery ambient temperature, patient albumin content, patient blood glucose content, and drainage volume, improving the accuracy and objectivity of the drainage volume relationship function.

[0069] According to an embodiment of the present invention, based on the drainage volume, the standard drainage volume, the patient recovery stage vector, the stoma patency recognition result, the stoma skin recognition result, the color recognition result, and the character recognition result, an artificial anal canal status monitoring score is determined, including: determining the artificial anal canal status monitoring score of the j-th patient on the r-th day after surgery according to formula (2) ,

[0076] ,

[0077] is the stoma patency recognition result for the j-th patient on the r-th date after surgery,

[0078] ,

[0079] is the stoma skin recognition result for the j-th patient on the r-th date after surgery,

When the j-th patient is in the early postoperative stage, the value of When the j-th patient is in the postoperative recovery stage, the value of When the j-th patient is in the long-term follow-up stage, the value of , where is the first preset drainage fluid volume threshold. In the early postoperative stage, if the drainage fluid volume is too small (e.g., less than 20 ml), it may indicate paralytic ileus. If the drainage fluid volume is too large (e.g., more than 200 ml), it indicates the risk of anastomotic leakage. The value of can be set to 110 ml (the average of the lower limit (20 ml) and the upper limit (200 ml) of the normal drainage fluid volume). is the second preset drainage fluid volume threshold. In the postoperative recovery stage, if the drainage fluid volume is too small (e.g., less than 50 ml), it may indicate paralytic ileus. If the drainage fluid volume is too large (e.g., more than 300 ml), it may indicate infectious diarrhea or short bowel syndrome. The value of is the standard drainage fluid volume of the j-th patient, representing the standard drainage fluid volume of the j-th patient in the long-term follow-up stage.

[0083] According to an embodiment of the present invention, is the relative difference between the drainage volume of the e-th drainage fluid discharge on the r-th day after surgery for the j-th patient and the standard drainage volume determined according to the recovery stage of the j-th patient. The smaller this ratio, the smaller the gap between the drainage volume of the e-th drainage fluid discharge on the r-th day after surgery for the j-th patient and the standard drainage volume of the corresponding recovery stage, and the better the state of the artificial anal canal of the patient. is the average value calculated according to the number of drainage fluid discharges.

[0091] Based on the subjective patient data, determine whether the patient has pain or persistent dull pain in the anal area during defecation, and determine the pain recognition result;

[0092] Based on the anastomosis CT image, determine whether there is fluid accumulation, abscess, or fistula around the anastomosis, and determine the anastomosis recognition result;

[0093] Based on the laboratory data, determine the fecal calprotectin content and C-reactive protein content;

[0094] Based on the pain recognition result, the anastomosis recognition result, the fecal calprotectin content, and the C-reactive protein content, determine the monitoring score of the anal canal state.

[0095] For example, ask the patient whether there is pain or persistent dull pain in the anal area during defecation. If there is pain or persistent dull pain, the pain recognition result is 0; if there is no pain or persistent dull pain, the pain recognition result is 1. Examine the CT image of the anastomosis to determine whether there is fluid accumulation, abscess or fistula around the anastomosis. Fluid accumulation and abscess usually appear as low-density areas, and the fistula usually appears as a low-density channel connecting two different hollow organs or tissues on the CT image. If there is fluid accumulation, abscess or fistula around the anastomosis, the anastomosis recognition result is 0; if there is no fluid accumulation, abscess or fistula around the anastomosis, the anastomosis recognition result is 1. Detect the fecal calprotectin content in the patient's feces and the C-reactive protein content in the patient's blood in the laboratory. Evaluate the anal canal status of the patient according to the pain recognition result, anastomosis recognition result, fecal calprotectin content and C-reactive protein content, and determine the anal canal status monitoring score.

[0096] According to an embodiment of the present invention, determining the anal canal status monitoring score according to the pain recognition result, the anastomosis recognition result, the fecal calprotectin content and the C-reactive protein content includes: determining the anal canal status monitoring score of the j-th patient on the r-th day after surgery according to formula (3) ,

[0097] (3),

[0098] wherein, if is a conditional function, is the fecal calprotectin content of the feces of the j-th patient on the r-th day after surgery, is the preset fecal calprotectin content threshold, is the C-reactive protein content of the blood of the j-th patient on the r-th day after surgery, is the preset C-reactive protein content threshold, is the pain recognition result of the j-th patient on the r-th day after surgery,

[0099] ,

[0100] is the anastomosis recognition result of the j-th patient on the r-th day after surgery,

[0101] .

[0102] According to an embodiment of the present invention, in formula (3), the value of the conditional function includes the following two cases. When When the fecal calprotectin content of the feces of the j-th patient on the r-th day after surgery is greater than or equal to the preset fecal calprotectin content threshold under certain conditions, if the fecal calprotectin content is greater than or equal to 150 μg / g, indicating the presence of intestinal inflammation or anastomotic fistula risk, then the preset fecal calprotectin content threshold is set to 150 μg / g, and the value of the conditional function is 0. When the conditions are not met, the value of the conditional function is 1.

[0103] According to an embodiment of the present invention, in the formula, the conditional function has the following two cases. When the conditions are met, the C-reactive protein content of the blood of the j-th patient on the r-th day after surgery is greater than or equal to the preset C-reactive protein content threshold, and there may be an infection phenomenon. The value of the conditional function is 0. If the C-reactive protein content is greater than 10 mg / L, it may indicate an infection, then the C-reactive protein content threshold is set to 10 mg / L. When the conditions are not met, the value of the conditional function is 1.

[0104] According to an embodiment of the present invention, is the pain recognition result of the j-th patient on the r-th day after surgery. If the j-th patient has a pain phenomenon on the r-th day after surgery, it may indicate anastomotic inflammation or nerve damage, and the state of the natural anal canal is poor. The value is 0, otherwise the value is 1. is the anastomosis recognition result of the j-th patient on the r-th day after surgery. If there is an abnormal phenomenon in the anastomosis image of the j-th patient on the r-th day after surgery, the state of the natural anal canal is poor. The value is 0, otherwise the value is 1.

[0105] According to an embodiment of the present invention, is to determine the anal canal state monitoring score according to the fecal calprotectin content status, C-reactive protein content status, patient subjective feeling status, and anastomosis image status.

[0106] In this way, the anal canal state monitoring score can be determined according to the pain recognition result, anastomosis recognition result, fecal calprotectin content, and C-reactive protein content. During the calculation process, the anal canal state of the patient can be evaluated from four aspects: fecal calprotectin content status, C-reactive protein content status, patient subjective feeling status, and anastomosis image status, improving the comprehensiveness and accuracy of the anal canal state monitoring score.

[0107] According to an embodiment of the present invention, in step S106, a monitoring report is generated based on the artificial anal canal status monitoring score and the anal canal status monitoring score.

[0108] For example, when the artificial anal canal status monitoring score is less than the set threshold of the artificial anal canal status monitoring score (such as, + + + + ), it indicates that there is an abnormality in the artificial anal canal. When the anal canal status monitoring score is less than the set threshold of the anal canal status monitoring score (such as 1), it indicates that there is an abnormality in the natural anal canal.

[0109] According to the method for monitoring the artificial anal canal and anal canal status information of the low rectal anastomosis according to the embodiment of the present invention, the status of the artificial anal canal can be monitored according to the drainage fluid condition and stoma condition to determine the artificial anal canal status monitoring score. The status of the natural anal canal can be evaluated according to the patient's subjective feelings, anastomosis CT images, and laboratory data to determine the anal canal status monitoring score. Further, a monitoring report is generated based on the artificial anal canal status monitoring score and the anal canal status monitoring score, improving the comprehensiveness and accuracy of the monitoring of the artificial anal canal and anal canal status information of the low rectal anastomosis. When determining the drainage fluid volume relationship function, the drainage fluid volume relationship function can be determined according to the historical drainage fluid volume, historical patient food intake, historical patient activity volume, historical patient recovery environment temperature, historical patient albumin content, and historical patient blood glucose content, accurately describing the relationship between the patient's food intake, patient activity volume, patient recovery environment temperature, patient albumin content, patient blood glucose content, and drainage fluid volume, and improving the accuracy and objectivity of the drainage fluid volume relationship function. When determining the artificial anal canal status monitoring score, the artificial anal canal status monitoring score can be determined according to the drainage fluid volume, standard drainage fluid volume, patient recovery stage vector, stoma patency recognition result, stoma skin recognition result, color recognition result, and property recognition result. During the calculation process, the status of the artificial anal canal can be evaluated from five aspects: the drainage fluid discharge volume, drainage fluid color, drainage fluid property, stoma patency, and skin condition around the stoma of the patient, improving the accuracy and comprehensiveness of the artificial anal canal status monitoring score. When determining the anal canal status monitoring score, the anal canal status monitoring score can be determined according to the pain recognition result, anastomosis recognition result, fecal calprotectin content, and C-reactive protein content. During the calculation process, the anal canal status of the patient can be evaluated from four aspects: the fecal calprotectin content status, C-reactive protein content status, patient subjective feeling status, and anastomosis image status, improving the comprehensiveness and accuracy of the anal canal status monitoring score.
