RESUMO
BACKGROUND: Delayed gastric emptying (DGE) after distal gastrectomy impacts patients' nutritional status and quality of life. The current treatments of DGE seem unsatisfactory or need invasive interventions. It is unknown whether transcutaneous electroacupuncture (TEA) is effective in treating DGE. METHODS: A total of 90 eligible participants who underwent distal gastrectomy will be randomly allocated to either the TEA group (n = 60) or the sham transcutaneous electroacupuncture (sham-TEA) group (n = 30). Each participant will receive TEA on the bilateral acupoints of Zusanli (ST36) and Neiguan (PC6) for 4 weeks. The primary outcomes will be the residual rates of radioactivity in the stomach by gastric scintigraphy and total response rates. The secondary outcomes will be endoscopic features, autonomic function, nutritional and psychological status, serum examination, and quality of life (QoL). The adverse events will also be reported. The patients will be followed up 1 year after the treatment. DISCUSSION: The findings of this randomized trial will provide high-quality evidence regarding the efficacy and safety of long-term TEA for treating DGE after distal gastrectomy. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2000033965. Registered on 20 June 2020.

BACKGROUND: At present, there is no ideal treatment for postoperative ileus (POI) after abdominal surgery. This meta-analysis aims to evaluate the efficacy of electroacupuncture (EA) and transcutaneous electroacupuncture (TEA) in improving postoperative POI. METHODS: We systematically screened randomized controlled trials (RCTs) from multiple databases and included 15 high quality RCTs. Two investigators independently conducted data extraction, risk of bias assessment and statistical analysis. Meta-analysis was performed by a random- (REM) or fixed-effect (FIXED) model. RESULTS: A total of 15 trials involving 965 participates were included. Meta-analysis results favored EA/TEA treatment for POI by analysis of time to first flatus [mean difference (MD) -11.60â¯h, I2â¯=â¯94%, REM)], time to first defecation (MD -12.94â¯h, I2â¯=â¯90%, REM), time to bowel sound recovery (MD -7.25â¯h, I2â¯=â¯85%, REM), time to first oral feeding (MD -15.76â¯h, I2â¯=â¯47%, REM) and length of hospital stay (MD -1.19â¯d, I2â¯=â¯44%, REM). Subgroup analysis of laparoscopic surgery patients also favored EA/TEA by analysis of time to first flatus (MD -2.46â¯h, I2â¯=â¯0%, FIXED), time to first oral feeding (MD -10.73â¯h, I2â¯=â¯0%, FIXED) and length of hospital stay (MD -1.30â¯d, I2â¯=â¯32%, REM). ST36 (Zusanli), ST37 (Shangjuxu) and ST39 (Xiajuxu) are preferred EA/TEA acupoints for treating POI. There was no significant difference in postoperative analgesic consumption between EA and control groups (Pâ¯=â¯0.39). No severe adverse events associated with EA/TEA were reported. CONCLUSION: This meta-analysis suggests that EA/TEA is a safe, effective treatment for POI after abdominal surgeries including laparoscopic surgery, and that EA/TEA does not relieve postoperative pain after abdominal surgery. There is significant heterogeneity of research on this subject, thus, a professional consensus is needed to establish a standard protocol for use of this technique.

AIM: To investigate the efficacy and safety of transcutaneous electroacupuncture (TEA) to alleviate postoperative ileus (POI) after gastrectomy. METHODS: From April 2014 to February 2017, 63 gastric cancer patients were recruited from the Second Affiliated Hospital of Zhejiang University School of Medicine, Hangzhou, China. After gastrectomy, the patients were randomly allocated to the TEA (n = 33) or control (n = 30) group. The patients in the TEA group received 1 h TEA on Neiguan (ST36) and Zusanli (PC6) twice daily in the morning and afternoon until they passed flatus. The main outcomes were hours to the first flatus or bowel movement, time to nasogastric tube removal, time to liquid and semi-liquid diet, and hospital stay. The secondary outcomes included postoperative symptom assessment and complications. RESULTS: Time to first flatus in the TEA group was significantly shorter than in the control group (73.19 ± 15.61 vs 82.82 ± 20.25 h, P = 0.038), especially for open gastrectomy (76.53 ± 14.29 vs 87.23 ± 20.75 h, P = 0.048). Bowel sounds on day 2 in the TEA group were significantly greater than in the control group (2.30 ± 2.61/min vs 1.05 ± 1.26/min, P = 0.017). Time to nasogastric tube removal in the TEA group was earlier than in the control group (4.22 ± 1.01 vs 4.97 ± 1.67 d, P = 0.049), as well as the time to liquid diet (5.0 ± 1.34 vs 5.83 ± 2.10 d, P = 0.039). Hospital stay in the TEA group was significantly shorter than in the control group (8.06 ± 1.75 vs 9.40 ± 3.09 d, P = 0.041). No significant differences in postoperative symptom assessment and complications were found between the groups. There was no severe adverse event related to TEA. CONCLUSION: TEA accelerated bowel movements and alleviated POI after open gastrectomy and shortened hospital stay.
