Acupuncture Combined with Early Enteral Nutrition on Patients with Postoperative Laparoscopic Common Bile Duct Exploration: A Prospective Randomized Trial

A comparative study of acupuncture combined with rehabilitation gymnastics on postoperative anal function of lower rectal cancer

BACKGROUND

From the anal function, inflammatory response and other indicators, acupuncture combined with rehabilitation gymnastics was applied to patients with cancer undergoing low resection, aiming to improve the prognosis of patients.

AIM

To explore the effects of acupuncture combined with rehabilitation gymnastics on anal function after lower rectal cancer surgery.

METHODS

From January 2020 to December 2022, 128 patients who underwent rectal cancer surgery in the Department of Oncology of Hebei Provincial Hospital of Traditional Chinese Medicine Hospital were selected and divided into two groups using the random number table method, with 64 patients in each group. Patients in the control group were not treated with acupuncture or rehabilitation gymnastics and served as blank controls. Patients in the study group were treated with acupuncture and rehabilitation gymnastics from the 7th postoperative day. The anal incontinence scores, changes in serum interleukin-4, interleukin-6, and interleukin-10 Levels, and serum motilin, 5-hydroxytryptamine, and vasoactive intestinal peptide levels were compared.

RESULTS

There were no significant differences in serum interleukin-4, interleukin-6, and interleukin-10 Levels between the groups before treatment (P > 0.05). After treatment, these levels were better than those of the control group (P < 0.05). There was no significant difference in the anal incontinence scores between the groups before and 7 d after surgery (P > 0.05). Anal incontinence scores in the study group were lower than those in the control group at 14 d, 21 d, and 28 d postoperatively (P < 0.05). There were no significant differences in serum motilin, 5-hydroxytryptamine, or vasoactive intestinal peptide levels between the groups before treatment (P > 0.05). After treatment, these levels were higher in the study group than in the control group, and vasoactive intestinal peptide level was lower in the study group than in the control group (P < 0.05).

CONCLUSION

Acupuncture combined with rehabilitation gymnastics can promote the recovery of anal function and reduce the inflammatory response in patients with lower rectal cancer after surgery.

Effect evaluation of different preventive measures for ileus after abdominal operation: A systematic review and network meta-analysis

Background

Different approaches to the prevention of postoperative ileus have been evaluated in numerous randomized controlled trials. This network meta-analysis aimed to investigate the relative effectiveness of different interventions in preventing postoperative ileus.

Methods

Randomized controlled trials (RCTS) on the prevention of postoperative ileus were screened from Chinese and foreign medical databases and compared. STATA software was used for network meta-analysis using the frequency method. Random-effects network meta-analysis was also used to compare all schemes directly and indirectly.

Results

A total of 105 randomized controlled trials with 18,840 participants were included in this report. The results of the network meta-analysis showed that intravenous analgesia was most effective in preventing the incidence of postoperative ileus, the surface under the cumulative ranking curve (SUCRA) is 90.5. The most effective intervention for reducing the first postoperative exhaust time was postoperative abdominal mechanical massage (SUCRA: 97.3), and the most effective intervention for reducing the first postoperative defecation time was high-dose opioid antagonists (SUCRA: 84.3). Additionally, the most effective intervention for reducing the time to initiate a normal diet after surgery was accelerated rehabilitation (SUCRA: 85.4). A comprehensive analysis demonstrated the effectiveness and prominence of oral opioid antagonists and electroacupuncture (EA) combined with gum.

Conclusion

This network meta-analysis determined that oral opioid antagonists and EA combined with chewing gum are the most effective treatments and optimal interventions for reducing the incidence of postoperative ileus. However, methods such as abdominal mechanical massage and coffee require further high-quality research.

Personalized checkpoint acupuncture can reduce postoperative pain after abdominal surgery-a STRICTA-conform pilot study

BACKGROUND

Optimal pain management is one of the core elements of Enhanced Recovery After Surgery (ERAS®) protocols and remains a challenge. Acupuncture (AC) is an effective treatment for various pain conditions. Systematic and personalized allocation of acupoints may be decisive for efficacy.

METHODS

Based on the predominant pressure sensitivity of six gastrointestinal (GI) checkpoints (G1-G6), we devised a method to detect personalized patterns of pain and a corresponding set of acupoints. We performed a single AC treatment with semi-permanent needles and assessed the visual analogue scale (VAS) score, pain threshold based on pressure algometry (PA), and temperature changes on abdominal skin areas before and 5 min after AC.

RESULTS

Between April and June 2021, thirty-eight patients were prospectively included in this pilot study. The mean reduction in subjective pain sensation as assessed by VAS was 86%, paralleled by an augmentation of the pain threshold as measured by PA by 64%. A small but significant increase in the skin temperature was observed above the abdominal surface. These effects were independent of the type of surgery.

CONCLUSION

Checkpoint acupuncture may be a complementary tool for postoperative pain management. Further investigations are needed to explore this analgesic effect.

Acupuncture effect on dumping syndrome in esophagus cancer patients with feeding jejunostomy: A study protocol for a single blind randomized control trial

INTRODUCTION

Esophagus cancer patients are at risk for malnourishment. Feeding jejunostomy is used in advanced esophagus cancer patients in order to support and supplement the patients' nutrition needs. In dumping syndrome, the food is rapidly introduced into the intestine at a rate that is faster than normal, it is associated with both digestive system and vasoactive symptoms. Dumping syndrome has an association with both esophagus cancer patients and feeding jejunostomy. In the mid and long term, dumping syndrome is an important issue that contributes to the risk of malnourishment in advanced esophagus cancer patients. In recent studies, acupuncture was effective in regulating digestive symptoms. Acupuncture is considered to be a safe intervention, that was previously shown to be effective in treating digestive-related symptoms.

METHODS

Sixty advanced esophageal cancer patients post-feeding jejunostomy will be divided into 2 equal groups, an intervention group (n = 30) and a control group (n = 30). Patients in the intervention group will receive acupuncture using the following acupoints: ST36 (Zusanli), ST37 (Shangjuxu), ST39 (Xiajuxu), PC6 (Neiguan), LI4 (Hegu), and Liv 3 (Taichung). Patients in the control group will receive shallow acupuncture on 12 non-acupoints (sham points), 1 cm from the above mention points. Patients and assessors will be blind to trial allocation. Both groups will receive acupuncture twice a week for 6 weeks. The main outcome measurements are: body weight, BMI, Sigstad's score, and the Arts' dumping questionnaire.

DISCUSSION

There are no previous studies that have examined the use of acupuncture on patients with dumping syndrome. This single-blind randomized control trial will investigate the effect of acupuncture on dumping syndrome in advanced esophagus cancer patients with feeding jejunostomy. The results will determine if verum acupuncture can affect dumping syndrome and prevent weight loss.

Effects of transcutaneous electrical acupoint stimulation on gastrointestinal dysfunction after gastrointestinal surgery: A meta-analysis

BACKGROUND

Postoperative gastrointestinal dysfunction (PGD) is a common complication in patients undergoing gastrointestinal surgery. Several studies have evaluated the effect of transcutaneous electrical acupoint stimulation (TEAS) on PGD, so we conducted a systematic review and meta-analysis to better understand these studies methodologic limitations and summarize clinical effects.

METHODS

Articles (published from January 2010 to April 2022) were searched from the following databases: Wanfang Database, China National Knowledge Infrastructure (CNKI), Cochrane Library, PubMed, Web of Science and Embase. Two authors conducted literature selection, data extraction and statistical analysis independently. This meta-analysis used RevMan 5.4 software to implement statistical analysis and applied Cochrane bias risk tool to assess methodologic weaknesses of included articles. We assessed the effect of TEAS on time to first flatus, first defecation and bowel sound recovery through meta-analyses using a random-effects model.

RESULTS

The meta-analysis included 10 articles including 1497 patients. This study showed that TEAS could effectively promote postoperative gastrointestinal function recovery by analyzing the time to first flatus (MD-14.81 h, 95% CI -15.88 to -13.75 h), time to first defecation (MD-14.68 h, 95% CI -20.59 to -8.76 h), time to bowel sound recovery (MD-5.79 h, 95% CI -10.87 to -0.71 h), length of hospital stay (MD-1.48d, 95% CI -1.86 to -1.11d), and the incidence of postoperative nausea and vomiting (PONV) (OR 0.41, 95% CI 0.29-0.58). In addition, we assessed the quality of the articles and found small sample sizes and lower methodological quality in some articles.

CONCLUSION

Our meta-analysis revealed that TEAS could be a nonpharmacological treatment for PGD in patients after gastrointestinal surgery. However, positive findings should be treated carefully and future studies with high quality and large samples are needed to support this results.

Perioperative transcutaneous electrical acupoint stimulation for improving postoperative gastrointestinal function: A randomized controlled trial

BACKGROUND

Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications in patients undergoing major abdominal surgery. Acupuncture has been used widely in gastrointestinal diseases due to its effectiveness and minimally invasive nature.

OBJECTIVE

This study evaluated the efficacy of using transcutaneous electrical acupoint stimulation (TEAS) during the surgery and postoperative recovery in patients with gastric and colorectal surgery for improving postoperative gastrointestinal function.

DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS

A total of 280 patients undergoing abdominal surgery were stratified by type of surgery (i.e., gastric or colorectal surgery) and randomly allocated into the TEAS group (group T) or the sham group (group S). Patients in group T received TEAS at LI4, PC6, ST36 and ST37. Patients in group S received pseudo-TEAS at sham acupoints. The stimulation was given from 30 min before anesthesia until the end of surgery. The same treatment was performed at 9 am on the 1st, 2nd and 3rd days after surgery, until the recovery of flatus in patients.

MAIN OUTCOME MEASURES

The primary outcome was the time to the first bowel motion, as detected by auscultation. The secondary outcomes included the first flatus and ambulation time, changes of perioperative substance P (SP), incidence of PGD, postoperative pain, postoperative nausea and vomiting (PONV) and some economic indicators.

RESULTS

The time to first bowel motion, first flatus and first ambulation in group T was much shorter than that in group S (P < 0.01). In patients undergoing colorectal surgery, the concentration of SP was lower in group T than in group S on the third day after the operation (P < 0.05). The average incidence of PGD in all patients was 25%, and the frequency of PGD was significantly lower in group T than in group S (18.6% vs. 31.4%, respectively; P < 0.05). TEAS treatment (odds ratio = 0.498; 95% confidence interval: 0.232-0.786) and type of surgery were relevant factors for the development of PGD. Postoperative pain score and PONV occurrence were significantly lower in group T (P < 0.01). Postoperative hospitalization days and the resulting cost to patients were greatly reduced in the TEAS group (P < 0.01).

CONCLUSION

Perioperative TEAS was able to promote the recovery of postoperative gastrointestinal function, reduce the incidence of PGD and PONV. The concentration of SP was decreased by TEAS treatment, which indicates that the brain-gut axis may play a role in how TEAS regulates gastrointestinal function.

Ecological niche modeling of Astragalus membranaceus var. mongholicus medicinal plants in Inner Mongolia, China

Radix Astragali is commonly used in traditional Chinese medicine, and its quality is closely related to ecological factors, such as climate and soil, in the production area. To provide high-quality Radix Astragali to Chinese and foreign markets, we used maximum entropy model and statistical analysis method, combined with data on ecological factors, Astragalus membranaceus var. mongholicus geographical distribution, and index component content to predict the ecological suitability distribution of A. membranaceus var. mongholicus and establish the relationship between astragaloside IV and calycosin-7-glucoside in this species and ecological factors. Subsequently, we could determine the suitability regionalization of high-quality A. membranaceus var. mongholicus in Inner Mongolia, China. The results showed that the standard deviation of seasonal changes in temperature (40.6%), precipitation in October (15.7%), vegetation type (14.3%), soil type (9.2%), and mean sunshine duration in the growing season (9.1%) were the top five most influential factors out of the 17 main ecological factors affecting the distribution of A. membranaceus var. mongholicus. The standard deviation of seasonal changes in temperature, precipitation in October, precipitation in April, soil pH, and mean sunshine duration in the growing season were found to be the key ecological factors affecting the accumulation of astragaloside IV and calycosin-7-glucoside in A. membranaceus var. mongholicus. The regions with the highest-quality A. membranaceus var. mongholicus were distributed in Baotou (Guyang County), Hohhot (Wuchuan County), and central Wulanchabu (Chahar Right Middle Banner, Chahar Right Back Banner, and Shangdu County) and its surroundings in Inner Mongolia. Baotou, Hohhot, and their surrounding areas were the main traditional production areas of A. membranaceus var. mongholicus, and central Wulanchabu was a potentially suitable distribution area of this species. The main production areas were consistent with the actual production base of A. membranaceus var. mongholicus. This study therefore provides a scientific basis to guide the cultivation of A. membranaceus var. mongholicus.
