Brief Summary

Delayed gastric emptying (DGE) after surgery mainly occurs after gastrointestinal surgery A functional gastric emptying disorder, clinically characterized by weak or absent gastric peristalsis, gastric motility disorders, or gastric emptying Gastric retention, fullness, nausea and other uncomfortable symptoms caused by delay.This study is based on clinical diagnosis and treatment practice, observing, collecting, and analyzing Whipple surgery, pancreatectomy, and gastric cancer Perioperative data of subtotal resection surgery, mainly observing the diagnosis and treatment of ear acupoints in Whipple surgery, pancreatectomy, and subtotal gastrectomy.The application effect of DGE after resection surgery, exploring the diagnosis and treatment of ear acupoints in Whipple surgery, pancreatic body and tail resection surgery, and Diagnostic value of perioperative related diseases in abdominal surgery such as subtotal gastrectomy, and collection of health records.By comparing and analyzing the ear acupoint information of patients with abdominal tumors, we aim to explore the ear acupoints of the volunteers. The possible relationship between image and resistance specificity and common tumors in the abdominal cavity.

Outcome Measures

Primary Outcomes (2)

  • Clinical total effective rate

    The clinical total effective rate of ear acupuncture treatment for postoperative DGE in the abdomen, including Whipple surgery, pancreatectomy, and subtotal gastrectomy. Efficacy evaluation criteria: Measure the subjective symptom score (Gastroparesis Cardinal Symptom Index, GCSI score) of patients with gastroparesis on the third day after surgery, and calculate the clinical efficacy index of ear acupuncture treatment using the following formula (efficacy index=\[(total score of symptoms before treatment - total score of symptoms after treatment) ÷ total score of symptoms before treatment × 100%\]). Among them, significant effect: efficacy index\>75%; Effective: Efficacy index of 25% to 75%; Invalid: Efficacy index\<25%. Total effective rate=(number of significantly effective cases+number of effective cases)/total number of cases x 100%.

    On the third day after surgery

  • Perioperative Anxiety Scale-7 (PAS-7)

    This scale was used to evaluate the anxiety of patients before surgery. This scale evaluates some of the patient's conditions regarding the operation, and then, based on the actual situation during the days of hospitalization, selects the appropriate option among 5 options, circling the corresponding numbers. The higher the score, the more severe the patient's preoperative anxiety level.

    24±2h after the start of AP or first visit, 12±2h before surgery, and 2 h before surgery

Secondary Outcomes (4)

  • Modified Pittsburgh Sleep Quality Index (M-PSQI)

    24±2h after the start of AP or first visit (T1), 12±2h before surgery (T2), and 72±2h post-operatively

  • Self-Rating Anxiety Scale (SAS) Score

    Multiple time points before and after surgery

  • Patient Satisfaction with Pre-operative Preparation Assessed with the Visual Analogue Scale (VAS-Satisfaction)

    Preoperative

  • Visual Analogue Scale for Pain (VAS-Pain)

    Multiple time points after surgery

Study Arms (3)

Surgical control group (Group A)

Patients who received ear acupuncture treatment (≥ 1 time) due to perioperative anxiety, pain, prevention/treatment of DGF, or other indications for ear acupuncture treatment in actual diagnosis and treatment were divided into two groups based on exposure factors. Patients who received ear acupuncture treatment were included in the surgical observation group (Group B), while other patients were included in the surgical control group (Group A). Both groups of patients were from the basic surgical ward of Peking Union Medical College Hospital and were planning to undergo abdominal surgeries such as Whipple, pancreaticoidectomy, and subtotal gastrectomy;

Healthy control group (Group C)

According to the surgical observation group (Group B), the healthy control group (Group C) consisted of healthy volunteers from the same period at the Beijing Union Medical College Hospital Health Examination Center.

Interventions

Ear point diagnosis and treatment is one of acupuncture and moxibustion methods, which originates from the theory of acupuncture and moxibustion meridians and is the product of the combination of modern Chinese medicine and western medicine, including two parts: auricular acupoint diagnosis and auriculotherapy. Ear point diagnosis refers to the determination of auricle positive reaction points through vision, touch, pressure and other methods to diagnose diseases in some parts of the body on the basis of ear point theory. Ear point treatment refers to the use of certain therapeutic devices on ear points to achieve the purpose of prevention and treatment of diseases by stimulating ear points, which are often carried out simultaneously in clinical practice.
