## Abstract

This paper mainly analyzes the feasibility of laparoscopic local gastrectomy for the treatment of benign gastric tumors, evaluating its curative effect, and the use of traditional Chinese medicine (TCM) such asHedyotis diffusa, Radix Pseudostellariae, yi, Pinellia ternata, Ophiopogon japonicus, wood fragrance, Perilla, Scutellaria baicalensis, Yuzhu, hawthorn, Artemisia annua, chicken yellow film, nail, and turtle, and clinical symptoms of statistical analysis of data mining. A total of 86 patients with gastric benign tumor were selected as the research object and were divided into observation group and control group with 43 cases in each by the random number table method. The control group received radical gastrectomy for benign tumor under laparoscopy, while the observation group received local gastrectomy under laparoscopy. Perioperative indexes such as operative time, intraoperative blood loss, and length of hospital stay were recorded in the two groups. Serum C-reactive protein (CRP) and carcinoembryonic antigen (CEA) levels were analyzed by enzyme-linked immunosorbent assay (ELISA), and the incidence of complications was compared. Based on the clinical analysis of the drug used, the results of association significance were selected, and the top ten results were selected in order of confidence and grouped according to clinical symptoms, respectively, as follows: (1) abdominal distension: Hedyotis diffusa, Radix Pseudostellariae, Poria cocos, Huckleberry, and Coix seed; (2) dry mouth: Poria cocos, Radix Radix Pseudostellariae, Coix seed, Pinellia tuber, and Radix Ophiopogonis. The results showed that the minimum operation time in the observation group was 159.7 ± 13.07 min and the maximum was 172.57 ± 2.47 min, which was lower than that in the control group (the minimum was 172.46 ± 12.45 min and the maximum was 186.49 ± 24.32 min). The length of hospital stay (6.51 ± 1.29 days) was lower than that in the control group (7.56 ± 1.42 days) (P < 0.05). The CEA and CRP levels decreased significantly in both groups after treatment (P<0.05). However, the observation group’s CEA was (4.21 ± 1.05) mg/L and CRP was (8.46 ± 1.25) μg/L. In the control group, CEA was (4.18 ± 1.02) mg/L and CRP was (8.39 ± 1.24) μg/L. There were no significant differences (P<0.05). The incidence of complications in the observed group was 4.7% lower than 7.0% in the control group (P<0.05). Therefore, laparoscopic local gastric resection for benign gastric tumors can effectively reduce the incidence of CEA and CRP level and complications and improve the perioperative indicators, which is worth popularizing in clinical practice.

## Body

## 1. Introduction

Gastric benign tumors account for about 3% of gastric tumors and have a higher incidence in the body of the stomach. According to different lesion sites, it can be divided into gastric wall mucosal epithelial tissue tumor and gastric wall interlobar tissue tumor. It is difficult to completely rule out the possibility of malignancy in clinical practice, so it is necessary to take surgical treatment. With the development of minimally invasive surgery technology and the emergence of various new devices, laparoscopic technology with its characteristics of no laparotomy, less bleeding, less trauma, safety, and effectiveness has become more and more prominently advantagous in the diagnosis and treatment of difficult abdominal diseases. However, the auxiliary role of laparoscopy in radical gastrectomy has been mostly reported, while the application effect of local resection of benign gastric tumor is rarely studied.Laparoscopic localization of small gastrointestinal neoplasms (benign lesions or early cancers without serosal invasion) is difficult. This leads to the failure of the operation. Therefore, how to quickly and accurately locate small tumors in laparoscopic gastrointestinal surgery has important clinical significance. Gastrointestinal endoscopy is an important method for the diagnosis and treatment of gastrointestinal polyps and tumors. Endoscopic excision, endoscopic mucosal resection, and subendoscopic mucosal dissection are common endoscopic methods for the treatment of gastrointestinal polyps and tumors. However, endoscopic treatment may not achieve the purpose of radical surgery for tumors with early malignant transformation or advanced intraepithelial neoplasia, and the postoperative recurrence rate is high. For large benign tumors or polyps, due to the wide base, the mucosal muscle layer is often involved, resulting in a high incidence of intraoperative and postoperative bleeding, perforation, and other complications. In addition, as endoscopic mucosal resection and endoscopic mucosal dissection require higher operational skills, a series of special equipment and instruments are needed. It is still controversial whether the treatment of early malignant tumors can be achieved completely, so the clinical promotion in the majority of primary hospitals is very limited.At present, most primary hospitals have been able to carry out laparoscopic gastrointestinal surgery independently, and endoscopic gastrointestinal tumor resection has gradually become the preferred surgical method. However, laparoscopy can only feel the lesions through visual or instrument indirect sensation, such as the expansion of intestinal volume, the invasion of intestinal serosal layer, and the operation forceps touching the hard mass of gastrointestinal tract, to judge the condition. For some gastrointestinal tumors with soft texture, lesions growing into the lumen, and no obvious changes in the intestinal canal, there may be blind areas in intraoperative positioning and judgment, which may lead to the conversion to open surgery. Endoscopy, barium enema, CT, and endoscopic staining all had certain errors or false negatives in the preoperative positioning of gastrointestinal tumors.With the increasing incidence of gastrointestinal neoplasms, there is a growing demand for the treatment of gastrointestinal neoplasms, and the research on the treatment of gastrointestinal neoplasms is also increasing. But at present, the first choice for gastrointestinal tumors is still surgical treatment combined with chemotherapy, radiotherapy, targeted therapy, etc. Traditional Chinese medicine combined with the above treatments can effectively improve the clinical symptoms of patients, prolong the survival period, improve the quality of life, improve the tolerance of radiotherapy and chemotherapy, reduce side effects, and have a very important role. Therefore, it is of great significance to study how to treat gastrointestinal tumors with traditional Chinese medicine and summarize the experience and medication habits of famous experts through data mining and other methods.The feasibility of laparoscopic local gastrectomy for the treatment of benign gastric tumors was analyzed, and its efficacy was evaluated, late and the spreadingHedyotis herb, Radix Pseudostellariae, yi, Pinellia, Radix Ophiopogonis, radix aucklandiae, purple Perilla, radix scutellariae, jade bamboo, hawthorn, purple Perilla, capillary artemisia, chicken’s gizzard-membrane, negundo vendor fingernails, turtle, the use of traditional Chinese medicine (TCM), and clinical symptoms of statistical analysis of data mining.The development of laparoscopy and traditional open surgery has been a hot spot. Based on qualified randomized controlled trials (RCTs), Obuchi et al. investigated the overall efficacy and safety of anterior laparoscopic surgery and traditional open surgery in patients with colorectal cancer, especially the difference in the incidence of postoperative deep vein thrombosis (DVT) [1]. Caron et al. compared the efficacy of traditional open surgery and laparoscopic surgery in the treatment of rectal cancer [2]. Single incision gastric surgery is used for various diseases such as gastric tumor and pancreatic pseudocyst [3]. Compared with traditional surgery, laparoscopic surgery for gastrointestinal neoplasms has the advantages of less trauma, less postoperative pain, and faster recovery of gastrointestinal function. Laparoscopic surgery has the same safety and reliability as open surgery in the treatment of gastrointestinal tumors. Hirota et al. discussed the clinical effect of laparoscopic surgery in the treatment of rectal stromal tumor and discussed its safety and feasibility [4]. Background virtual reality technology has been widely used in laparoscopic surgery, especially in the training process. Li et al. evaluated the learning curve of virtual reality and compared it with other training methods or methods without training [5].Research on how to treat gastrointestinal tumors with traditional Chinese medicine is also developing. Wang et al. summarized the related theories, treatment principles, and medication of TCM surgery and discussed the significance of TCM surgery theory in the treatment of tumor syndrome differentiation [6]. Berbiglia et al. discussed the efficacy of basic treatment combined with Chinese herbal compound Qiguiyishen decoction in the treatment of chronic kidney disease [7].The mining and application of medical big data have become a powerful driving force for the continuous development of clinical multicenter research. Under the current social background, promoting the construction of hospital informatization provides a powerful model for carrying out multicenter research. Clinical multicenter research in the era of big data not only helps us to have a deeper understanding of human diseases, but also can guide personalized diagnosis and intelligent decision-making [8]. In data mining, association rule mining is a promising technique for finding hidden patterns in large databases. The main problem of association rule mining in medical data is that a large number of rules are found, most of which are irrelevant [9]. Pelletier et al. used data mining to study the medication rules of famous TCM practitioners in the treatment of cervical spondylosis [10]. Rao et al. presented a new method for prediction and prognosis of heart disease based on data mining algorithm [11].Therefore, on this basis, the feasibility of laparoscopic local gastrectomy for the treatment of gastric benign tumors was analyzed, and its efficacy was evaluated. Data mining was used to conduct statistical analysis on the later drug use and clinical symptoms. According to the clinical analysis of drug use, selecting the results of related significance, the top ten results are selected according to the confidence order and grouped according to the clinical symptoms, respectively, (1) abdominal distension: white snake grass, crown ginseng,Poria cocos, woody fragrance, and raw seed; (2) dry mouth: Poria cocos, crown ginseng, raw seed Job, Pinellia fasha, and Maidong. The results show observation surgical time (159.74 ± 13.07) min, no. min, (172.45 ± 24.57) mL, hospitalization (6.51 ± 1.29) d was lower than the control group (172.46 ± 12.45) min, (183.76 ± 24.32) mL, (7.56 ± 1.42) d (P<0.05). The CEA and CRP levels decreased significantly in both groups after treatment (P<0.05). However, the observation group CEA level was (4.21 ± 1.05) mg/L and CRP was (8.46 ± 1.25) μg/L. In the control group, CEA was (4.18 ± 1.02) mg/L and CRP was (8.39 ± 1.24) μg/L, There were no significant differences (P<0.05). The incidence of complications in the observed group was 4.7% lower than 7.0% in the control group (P<0.05). Therefore, laparoscopic local gastric resection for benign gastric tumors can effectively reduce the incidence of CEA and CRP level and complications and improve the perioperative indicators, which is worth popularizing in clinical practice.


## 2. Research Methods

### 2.1. Treatment Methods

Gastric stroma (gastric stromal tumors, GSTs) is the most common intergastric lobe-derived tumor, which is clinically easy to be misdiagnosed as gastric leiomyomas and neurogenic tumors. But in recent years with the gastrointestinal stroma (gastrointestinal stromal tumors, GIST), the depth of the study has gradually clearly recognized the pathophysiological characteristics and molecular biological foundations of GIST. Since GSTs rarely cause little lymph node metastasis, therefore, extensive lymph node cleaning is not required during the operation. The lesion was locally removed for those with a tumor diameter of less than 5 cm. With the development of laparoscopic surgical instruments and mature operation technology, laparoscopic treatment of gastrointestinal benign tumors, and traditional open surgery, more and more gastrointestinal surgeons began to use minimally invasive technology to handle GSTs, but minimally invasive surgery is for small lesions (less than 2 cm), and some special parts of the tumor, such as cavity growth or posterior gastric wall tumor, are difficult to locate, so the accurate positioning of lesions in GSTs minimally invasive treatment is particularly important. Moreover, tracheal intubation is used for general anesthesia. The patient took the head, high foot, and lower legs apart. The surgeon stood between the patient's legs, and the assistants stood on the left and right sides of the patient. First, a 10 mm trocar is placed under the umbilical cord as the observation hole. A 10 mm trocar is placed 6 cm on the left side of the umbilical cord as the main operating hole, 3 cm on the right side of the midpoint of the umbilical cord. In addition, a 5 mm trocar as the auxiliary operating hole and another 5 mm trocar each were placed under the costal edge of the right clavicle and the left axillary front for use to assist in the exposure of the surgical field. Air pressure is maintained at 13 mm Hg. Fibrous gastroscopy was inserted from the patient's mouth. To initially locate the tumor according to the preoperative gastroscopy data, gastroscopic and laparoscopic operators cooperate with each other inside and outside the gastric cavity. The tumor was pushed according to the gastric cavity. The operator was positioned according to the gastroscopy and a suture needle was used to locate the tumor. Depending on the site of the tumor, relevant surgical methods were followed: (1) 5 cases of local resection of ultrasonic knife tumor: for tumors in particular sites, GSTs, at the small bend side below the cardia, gastrointestinal wall incision was sutured 1.5 cm from the tumor, strengthening the sutured pulp muscle layer. Avoid external cavity wedge removal causing cardiac stenosis. (2) Tumor of the stomach base and body: after the removal of the spleen and stomach ligament, liver and gastric ligament, and gastric colon ligament, suture the traction tumor. The tumor and its surrounding gastric tissues were removed by endoscopic surgical cutting suture (Endo-GIA) wedge. (3) Part of the gastrectomy: by most of the gastrectomy, jejunal anastomosis was created after removal of part of the stomach, and the digestive tract is reconstructed. After surgery, routine gastrointestinal decompression, rehydration, and appropriate nutrition support were applied. After prophylactic application of antibiotic for 2-3 days and for intestinal function to restore anal exhaust, the gastrointestinal decompression tube was removed and the patient was told to follow the fluid diet and then gradually return to the normal diet.


### 2.2. Observation Indicators

(1) Perioperative indexes such as operative time, intraoperative blood loss, and length of hospital stay were recorded in the two groups. (2) Analysis of serum related indexes: fasting venous blood 2 mL was collected. After centrifuge separation, serum CRP (reference value ≤10 mg/L) and CEA (reference value ≤5.9μg/L) were analyzed by ELISA. A benign tumor is generally less than 20 μg/L, while that >20 μg/L suggests digestive tract malignant tumor level. (3) Comparison of prognosis: the incidence of complications between the two groups was recorded.


### 2.3. Statistical Methods

SPSS19.0 software was used to process the data, the counting data was expressed as %, andχ2 test was used. Measurement data were expressed as (x ± s) and t-test was performed. P<0.05 was considered statistically significant.


### 2.4. Establishment of Medication Database in the Later Stage

Since TCM prescriptions are somewhat different from general data and data have their own specialty, Excel, a type of general data processing software, is first used to conduct standardized data sorting and cleaning. Then all the patients’ names, ages, genders, clinical symptoms, tongue coating, pulse, pathogenesis, treatment, prescription drug disease diagnosis, and other items were recorded into the Medcase V3.2 data mining system. The establishment of medical case collection and storage database, the use of enhanced association rules data mining, operation model mining, strong objectivity, and statistics have a strong operability.

According to the results of this data analysis, the results with relevant significance were selected, and the top ten results were selected in order of confidence and then grouped according to clinical symptoms. Two groups were obtained as follows:(1)
Abdominal distension: Hedyotis diffusa, Radix Pseudostellariae,Poria cocos, Huckleberry, and Coix seed(2)
Dry mouth:Poria cocos, Radix Pseudostellariae, Coix seed, Pinellia tuber, and Radix OphiopogonisFigure 3
Clinical symptoms and confidence of drug association.In the first group, Fulia Cocoa invigorates the spleen and moistens the spleen, Coix seed invigorates the spleen and moistens the body and regulates the Qi, and Xanthomum aromaticum invigorates the Qi and relieve pain. The above three herbs are for the treatment of spleen deficiency, Qi stagnation and abdominal distension, while the addition of Pizonaria Radix is intended to invigorate the spleen and nourish the Yin at the same time. The body of patients with gastrointestinal tumor is also cremative and dryness, and Qi is harmful to fluid. Qi regulating drugs are also easy to injure Yin. Therefore, when treating patients with tumor and abdominal distension, we should not forget to invigorate spleen and nourish Yin while moving Qi. Although there is no indication in the main treatment effect of Hedyotis diffusa on the treatment of abdominal distension, it has the effect of clearing away heat and detoxifying dampness, and can treat cancer at the same time. In tumor patients, there is a lot of dampness and heat in the sputum and silt, which leads to Qi stagnation, and Qi stagnation leads to abdominal distension. Herbiditis diffusina is used to reduce dampness and fight cancer, the dispersion leads to Qi circulation, and abdominal distension is removed by itself. This shows Professor Zhou Chunxiang’s medication style of taking specimens into full play in the treatment of tumor patients with concurrent symptoms [12].A second group of drugs in Radix Pseudostellariae Qi and nourishing Yin, dwarf lilyturf Yin fluid, and Poria coco invigorates the spleen and changes the moisture, the seed of Job's tears changes the moisture and benefits the water, and the method Pinellia dryness and dampness reduces the phlegm. Teacher Zhou believes that the gastrointestinal tract tumor patients due to phlegm dampness in the knot block Qi machine, resulting in that the body fluid cannot be spread in the mouth and tongue caused by dry mouth, so in nourishing Yin at the same time pay attention to invigorating spleen dampness phlegm. According to the exploration attempt and summary of this study, laparoscopic combined gastroscopy GSTs with minimally invasive indications have the following advantages: (1) they quickly and accurately locate the tumor and shorten the operation time; (2) they can effectively avoid simple laparoscopic surgery due to small or small tumor and reduce the unnecessary transfer rate; (3) they can improve the accuracy of resection range and ensure negative resection; (4) they have the advantages of small trauma and rapid recovery compared with traditional abdominal surgery.

## 4. Conclusions

At present, most grassroots hospitals have been able to independently carry out laparoscopic gastrointestinal surgery independently, and endoscopic gastrointestinal tumor resection has gradually become the first choice of surgery. However, laparoscopy can only feel the lesion through visual or instrumental indirect feeling, such as the expansion of the intestinal volume, the invasion of the intestinal plasma membrane, and the operation of pliers to touch the hard gastrointestinal mass to determine the condition. For some gastrointestinal tumors with soft texture and lesions growing into the cavity, the intestinal tube may not change significantly due to the intraoperative positioning and judgment of blind spots and may lead to transabdominal surgery. Endoscopic, barium enema, and CT endoscopic staining all have some errors or false negative conditions in the preoperative positioning of gastrointestinal tumors. This paper mainly analyzed the feasibility of laparoscopic local gastrectomy for the treatment of gastric benign tumors, evaluated its efficacy, and conducted data mining and statistical analysis on the later drug use and clinical symptoms. According to the clinical analysis of drug use, the results with correlation significance were selected, and the top ten results were sorted by confidence and grouped according to clinical symptoms, respectively, as follows: (1) abdominal distension: Hedyotis diffusa, Radix Pseudostellariae,Poria cocos, Huckleberry, and Coix seed; (2) dry mouth: Poria cocos, Radix Radix Pseudostellariae, Coix seed, Pinellia tuber, and Radix Ophiopogonis. The results showed that the operation time of the observation group was (159.74 ± 13.07) min, intraoperative blood loss was (172.45 ± 24.57) mL, and the length of hospital stay (6.51 ± 1.29) d was lower than that of control group: (172.46 ± 12.45) min, (183.76 ± 24.32) mL, and (7.56 ± 1.42) d (P<0.05). After treatment, the levels of CEA and CRP in both groups were significantly decreased (P<0.05), but the CEA of observation group was (4.21 ± 1.05) mg/L and CRP was (8.46 ± 1.25) μg/L, compared with control group whose CEA and CRP were (4.18 ± 1.02) mg/L and (8.39 ± 1.24) μg/L. There was no significant difference between the two groups (P<0.05). The incidence of complications in the observation group was 4.7% lower than that in the control group (7.0%, P<0.05). Therefore, laparoscopic local gastrectomy for benign gastric tumors can effectively reduce the levels of CEA and CRP and the incidence of complications is worthy of clinical promotion to improve the perioperative indexes.
