ABSTRACT
BACKGROUND: Post-operative pain of endoscopic submucosal dissection (ESD) is always be overlooked and undertreated by endoscopists. However, the incidence of moderate to severe pain after ESD is as high as 44.9% to 62.8%, which can greatly affect the patient's recovery, reduce their satisfaction, and extend their hospital stay. Transcutaneous electrical acupoint stimulation (TEAS) have been shown to reduce postoperative pain and enhance gastrointestinal (GI) function recovery in patients undergoing abdomen surgery. However, there is no evidence regarding on the effect of TEAS on post-operative pain and complications in patients undergoing ESD. Therefore, we aim to investigate whether perioperative TEAS treatment is superior to the sham acupuncture in terms of post-ESD pain and GI function recovery. METHODS: This study is a prospective, randomized controlled trail, which is single-blinded and in single center. A total of 120 patients undergoing elective gastric and esophageal ESD surgery in Beijing Friendship Hospital, Capital Medical University, will be involved in this study. These individuals will be stratified according to the type of ESD surgery (i.e. gastric or esophageal procedure) and be randomly divided into two groups. L14, PC6, ST36 and ST37 will be stimulated at the TEAS treatment group, and the control group will receive simulation at four sham acupoints. The primary outcome is post-EDS VAS score at the time of entering PACU, 10 min, 20 min, 30 min, 1 h, 2 h, 4 h, 6 h, 18 h, 24 h, 48 h after the surgery. The secondary outcomes include the anesthesia-associated parameters, sedation score, nausea and vomiting score, shivering score, recovery of gastrointestinal function, satisfaction of patients to anesthesia, incidence of postoperative complications, QLQ-C30 life quality scale, and the economic indicators. DISCUSSION: The results of this study will confirm that continuous preventive application of TEAS can alleviate the postoperative pain among patients with gastric and esophageal ESD surgery and accelerate the recovery of post-ESD gastrointestinal function.

BACKGROUND: Although proton pump inhibitors (PPIs) are widely used in the prevention of gastric bleeding caused by endoscopic submucosal dissection (ESD), there is no consensus on the optimal regimen for these patients. Therefore, we aim to investigate whether intermittent use of low-dose PPI is sufficient to prevent post-ESD bleeding. METHODS: This multicenter, non-inferiority, randomized controlled trial was conducted at 9 hospitals in China. Consecutive eligible patients with a diagnosis of gastric mucosal lesions after ESD treatment were randomly assigned (1:1) to receive either intermittent low-dose or continuous high-dose PPIs treatment. After three days, all patients administered orally esomeprazole 40 mg once a day for 8 weeks. The primary endpoint was post-ESD bleeding within 7 days. Analysis was done according to the intention-to-treat principle with the non-inferiority margin (Δ) of 5%. RESULTS: 526 consecutive patients were assessed for eligibility from 30 September 2017 to 30 July 2019, of whom 414 were randomly assigned to low-dose (n = 209) or high-dose (n = 205) esomeprazole treatment group without dropouts within7 days. The total post-ESD bleeding is occurred in 13 (6.2 %, 95 % CI 3.3-9.6) of 209 within 7 days in the intermittent low-dose group, and 12 (5.9 %, 95 % CI 2.9-9.3) of 205 in the continuous high-dose group. The absolute risk reduction (ARR) was 0.4 % (-4.2, 4.9). One month after ESD, There are 44 patients (21.1 %, 95 % CI 15.8, 26.8) and 39 patients (19.0 % 95 % CI 13.7, 24.4) in scar stage respectively in low-dose group and high-dose group (P = 0.875).The hospital costs in the low-dose PPI group was lower than high -dose group (P = 0.005). CONCLUSION: The intermittent use of low-dose PPIs is sufficient to prevent post-ESD bleeding. It might be applied in clinical practice to prevent post-ESD bleeding and reduce the costs related to PPIs.
