Predictive modeling of postoperative gastrointestinal dysfunction: the role of serum bilirubin, sodium levels, and surgical duration in gynecological cancer care.

OBJECTIVE: To elucidate the role of preoperative serum bilirubin and sodium levels, along with the duration of surgery, in predicting postoperative gastrointestinal dysfunction (POGD) following gynecological cancer surgery, informing tailored perioperative strategies. METHODS: We conducted a retrospective analysis of 281 patients undergoing gynecological cancer surgery between 2018 and 2023. This analysis focused on preoperative serum bilirubin and sodium levels and intraoperative factors (surgical duration) as potential predictors of POGD. Logistic regression models were utilized for analysis, controlling for relevant confounders. RESULTS: Elevated preoperative serum bilirubin was associated with a reduced risk of POGD (mean level in non-POGD cases: 14.172 ± 4.0701, vs. POGD cases: 9.6429 ± 3.5351; p <  0.001), suggesting a protective role. Lower preoperative sodium levels were identified in the POGD group (136.26 mEq/L [IQR: 135.2-137.63]) compared to the non-POGD group (139.32 mEq/L [IQR: 137.7-140.75]; p <  0.001), highlighting its predictive value. Additionally, longer surgical duration was associated with increased POGD incidence, with POGD cases experiencing surgeries lasting 6.1547 ± 1.9426 hours compared to 4.5959 ± 1.5475 hours in non-POGD cases (p <  0.001). CONCLUSION: Our findings underscore the importance of serum bilirubin, sodium levels, and surgical duration as significant predictors of POGD in patients undergoing gynecological cancer surgery. These indicators should be integrated into a predictive model, aiding clinicians in identifying high-risk patients, allowing for personalized perioperative care adjustments, potentially mitigating POGD risks.

Enhanced recovery after surgery promotes the postoperative recovery of lung and gastrointestinal function of pseudomyxoma peritonei. / åŠ é€Ÿåº·å¤å¤–ç§‘ä¿ƒè¿›è ¹è†œå‡é»æ¶²ç˜¤æœ¯åŽè‚ºä¸Žèƒƒè‚ é“åŠŸèƒ½çš„åº·å¤.

OBJECTIVES: Pseudomyxoma peritonei (PMP) is a rare low-grade malignant tumor, which is difficult to operate with many postoperative complications. In recent years, enhanced recovery after surgery (ERAS) has been greatly developed in the perioperative management of surgical diseases, and it plays an important role in improving the postoperative prognosis of surgical patients. This study was conducted to explore the application of ERAS in the perioperative management of PMP patients, and to study the effect of ERAS on postoperative respiratory and digestive tract complications. METHODS: We retrospectively analyzed clinical data of patients with PMP from January 2014 to December 2018. These patients were treated with surgery in our center and they were divided into an observation group and a control group. The patients in the control group didn't perform ERAS in perioperative period, and patients in the observation group was performed ERAS. Then, we analyzed and compared the postoperative pulmonary complications (PPC) and gastrointestinal function between the 2 groups. RESULTS: There was no significant difference in the incidence of atelectasis, pleural effusion, pulmonary infection and acute respiratory distress syndrome (ARDS) between the two groups, but the total incidence of PPC in the observation group was significantly lower than that in the control group (P=0.032). The incidence of postoperative gastrointestinal dysfunction (PGID) in the observation group was significantly lower than that in the control group (P=0.025), and the postoperative first exhaust time, first defecation time, oral feeding time, and albumin level in the observation group were all better than those in the control group (all P<0.05). CONCLUSIONS: ERAS can significantly reduce the incidence of postoperative PPC and PGID in the PMP patients and improve their postoperative recovery.

Clinical efficacy of acupuncture in treating postoperative gastrointestinal dysfunction of colorectal cancer, a systematic review and Meta analysis. / é’ˆåˆºæ²»ç–—ç»“ç›´è‚ ç™Œæœ¯åŽèƒƒè‚ åŠŸèƒ½éšœç¢ç–—æ•ˆçš„ 系统评价和Meta分析.

OBJECTIVES: To evaluate the efficacy of acupuncture in the treatment of postoperative gastrointestinal dysfunction(POGD) of colorectal cancer. METHODS: Randomized controlled trials of acupuncture in the treatment of POGD were retrieved from 7 databases including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, VIP Chinese Journal Service Platform, WanFang Data Knowledge Service Platform, and China Biology Medicine disc. The search period ranged from the inception of the databases to November 10th, 2022. The quality of the included literature was assessed using the Cochrane bias risk assessment tool and the modified Jadad scale. Meta analysis was conducted using RevMan 5.4. Regression analysis and bias risk analysis were performed using Stata 16.0. Trial sequential analysis was conducted using TSA 0.9 software. RESULTS: A total of 27 randomized controlled trials involving 2 629 patients were included. Intervention measures included manual acupuncture, electroacupuncture, transcutaneous acupoint electrical stimulation, warm acupuncture, and thumb-tack needle. The results showed that acupuncture treatment significantly reduced time to tolerance of liquid diet after surgery (MD=-13.70, 95% CI=ï¼»-17.94, -9.46ï¼½, P<0.000 01), time to first defecation (MD=-18.20, 95% CI=ï¼»-22.62, -13.78ï¼½, P<0.000 01), time to first flatus (MD=-16.31, 95% CI=ï¼»-20.32, -12.31ï¼½, P<0.000 01), time to bowel sounds recovery (MD=-11.91, 95% CI=ï¼»-14.01, -9.81ï¼½, P<0.000 01), and length of hospital stay (MD=-1.49, 95% CI=ï¼»-2.27, -0.70ï¼½, P=0.000 2). Regression analysis indicated that cancer type, study quality and number of acupuncture were the main sources of heterogeneity. Bias analysis suggested potential publication bias risks. Trial sequential analysis indicated that the required number of cases had been met and the conclusion was reliable. CONCLUSIONS: Acupuncture is an effective intervention for promoting gastrointestinal recovery in patients undergoing colorectal cancer surgery. Further large-sample and well-designed clinical trials are still needed to compare different acupuncture techniques.

The efficacy of preemptive multimodal analgesia in elderly patients undergoing laparoscopic colorectal surgery: a randomized controlled trial.

Objective To evaluate the effectiveness of preemptive multimodal analgesiain elderly patients undergoing laparoscopic colorectal surgery. Methods A prospective randomized controlled study was conducted in the Department of Gastrointestinal Surgery of the Second Hospital of Hebei Medical University from January 2022 to December 2022. A total of 133 patients were included according to the criteria and randomly divided into preemptive analgesia (PRA) group (test group, 67patients) and postoperative analgesia (POA) group (control group, 66patients). Results The Visual Analog Scale (VAS)scores of PRA group 24 h, 48 h, and 72 h after operation were lower than those of POA group, and the difference was statistically significant, P < 0.001.The incidences of postoperative gastrointestinal dysfunction (POGD) and postoperative delirium (POD)in PRA group were 13.43% and 8.98%, respectively, which were significantly lower than those in POA group (31.82% and 24.24%), P < 0.05. The levels of IL-6 and IL-10 in PRA group after the operation were 17.54 ± 2.13 ng/L and 15.57 ± 1.71 ng/L respectively, which were lower than those in POA group (25.45 ± 2.95 ng/L and 23.45 ± 1.88 ng/L), P < 0.05. The level of acetylcholinesterase(AchE) was 56.34 ± 5.62 nmol/L in the POA group, which was significantly higher than that in the POA group (49.59 ± 5.52 nmol/L), P < 0.001. Conclusion Preemptive multimodal analgesia can reduce the incidence of POGD and POD in elderly patients undergoing laparoscopic gastrocolic surgery, improve the recovery process of postoperative gastrointestinal function, increase the concentrations of propionic acid and butyric acid in short chain fatty acids (SCFAs) and the number of beneficial intestinal bacteria.

Leveraging Nursing Assessment for Early Identification of Post Operative Gastrointestinal Dysfunction (POGD) in Patients Undergoing Colorectal Surgery.

Background: Postoperative gastrointestinal dysfunction (POGD) remains a common morbidity after gastrointestinal surgery. POGD is associated with delayed hospital recovery, increased length of stay, poor patient satisfaction and experience, and increased economic hardship. The I-FEED scoring system was created by a group of experts to address the lack of a consistent objective definition of POGD. However, the I-FEED tool needs clinical validation before it can be adopted into clinical practice. The scope of this phase 1 Quality Improvement initiative involves the feasibility of implementing percussion into the nursing workflow without additional burden. Methods: All gastrointestinal/colorectal surgical unit registered nurses underwent comprehensive training in abdominal percussion. This involved understanding the technique, its application in postoperative gastrointestinal dysfunction assessment, and its integration into the existing nursing documentation in the Electronic Health Record (EHR). After six months of education and practice, a six-question survey was sent to all inpatient GI surgical unit nurses about incorporating the percussion assessment into their routine workflow and documentation. Results: Responses were received from 91% of day-shift nurses and 76% of night-shift registered nurses. Overall, 95% of the nurses were confident in completing the abdominal percussion during their daily assessment. Conclusion: Nurses' effective use of the I-FEED tool may help improve patient outcomes after surgery. The tool could also be an effective instrument for the early identification of postoperative gastrointestinal dysfunction (POGD) in surgical patients.

BACKGROUND: Explore the risk factors of gastrointestinal dysfunction after gastrointestinal tumor surgery and to provide evidence for the prevention and intervention of gastrointestinal dysfunction in patients with gastrointestinal tumor surgery. AIM: To investigate the potential risk factors for gastrointestinal dysfunction following gastrointestinal tumor surgery and to present information supporting the prevention and management of gastrointestinal dysfunction in surgery patients. METHODS: Systematically searched the relevant literature from PubMed, Web of Science, Cochrane Library, Embase, CNKI, China Biomedical Database, Wanfang Database, and Weipu Chinese Journal Database self-established until October 1, 2022. Review Manager 5.3 software was used for meta-analysis after two researchers independently screened literature, extracted data, and evaluated the risk of bias in the included studies. RESULTS: A total of 23 pieces of literature were included, the quality of which was medium or above, and the total sample size was 43878. The results of meta-analysis showed that the patients were male (OR = 1.58, 95%CI: 1.25-2.01, P = 0.002) and ≥ 60 years old (OR = 2.60, 95%CI: 1.76-2.87, P < 0.001), physical index ≥ 25.3 kg/m2 (OR = 1.6, 95%CI: 1.00-1. 12, P = 0.040), smoking history (OR = 1.89, 95%CI: 1.31-2.73, P < 0.001), chronic obstructive pulmonary disease (OR = 1.49, 95%CI: 1.22-1.83, P < 0.001), enterostomy (OR = 1.47, 95%CI: 1.26-1.70, P < 0.001), history of abdominal surgery (OR = 2.90, 95%CI: 1.67-5.03, P < 0.001), surgical site (OR = 1.2, 95%CI: 1.40-2.62, P < 0.001), operation method (OR = 1.68, 95%CI: 1.08-2.62, P = 0.020), operation duration (OR = 2.65, 95%CI: 1.92-3.67, P < 0.001), abdominal adhesion grade (OR = 2.52, 95%CI: 1.90-3.56, P < 0.001), postoperative opioid history (OR = 5.35, 95%CI: 3.29-8.71, P < 0.001), tumor TNM staging (OR = 2.58, 95%CI: 1.84-3.62, P < 0.001), postoperative blood transfusion (OR = 2.92, 95%CI: 0.88-9.73, P = 0.010) is a risk factor for postoperative gastrointestinal dysfunction in patients with gastrointestinal tumors. CONCLUSION: There are many factors affecting gastrointestinal dysfunction in gastrointestinal patients after surgery. Clinical staff should identify relevant risk factors early and implement targeted intervention measures on the basis of personalized assessment to improve the clinical prognosis of patients.

Effect of acupuncture therapy for postoperative gastrointestinal dysfunction in gastric and colorectal cancers: an umbrella review.

Background: Gastrointestinal dysfunction is a prevalent postoperative complication in patients undergoing surgery for gastric cancer and colorectal cancer. Acupuncture holds promise as a great potential therapeutic intervention. The efficacy of acupuncture therapy for postoperative gastrointestinal dysfunction has been assessed in some studies, however, the variability in results and study quality influences practical clinical application. Therefore, it is necessary to summarize and analyze the published clinical research data in this field. Objective: This study aimed to synthesize evidence from systematic reviews and meta-analyses in order to assess the efficacy of acupuncture therapy for postoperative gastrointestinal dysfunction in patients with gastric and colorectal cancer. Design: Umbrella review of systematic reviews and meta-analyses. Methods: We searched China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform (Wanfang), China Science and Technology Journal Database (VIP), Chinese biomedical literature service system (SinoMed), PubMed, Embase, Cochrane Library, and Web of Science for all systematic review/meta-analysis of acupuncture for postoperative gastrointestinal dysfunction in gastric and colorectal cancers. From the establishment of the database to July 8, 2023. Two independent reviewers conducted literature extraction and evaluation. The quality of included studies was assessed using The preferred reporting items for systematic reviews and meta-analysis statements 2020 (PRISMA2020), the quality of the methods was assessed using a measuring tool to assess systematic reviews 2 (AMSTAR 2), and the level of evidence was assessed using the grading of recommendations assessment, development, and evaluation (GRADE). The statistical analysis was conducted using RevMan 5.4, and the effect size was expressed as Odds Ratio (OR), Mean Difference (MD), and 95% confidence interval (CI) based on the extracted data type (test level α= 0.05). The heterogeneity was assessed using the I 2 statistic and Q-test (χ2). The outcome indicators such as time to first defecation and time to first flatus were utilized as endpoints to assess the efficacy of different acupuncture therapies. Results: A total of six systematic reviews/meta-analyses were included in this study, involving 12 different acupuncture therapies. PRISMA 2020 indicated that the studies all scored between 13-20.5. There were deficiencies in protocol and registration, assessment of the quality of evidence for outcome indicators, risk of bias, and declaration of conflict of interest. The AMSTAR 2 evaluations showed that five studies were very low quality and one was low quality. The level of evidence for various acupuncture interventions varied from very low to moderate.For patients with gastrointestinal dysfunction after gastric cancer surgery, ear acupressure [MD=-11.92, 95% (-14.39,-9.44), P<0.00001], moxibustion [MD=-19.16, 95% (-23.00,-16.22), P<0.00001], warm needling [MD=-12.81, 95% (-17.61,-8.01), P<0.00001], acupoint application [MD=-6.40, 95% (-10.26,-2.54), P=0.001], manual acupuncture [MD=-18.32, 95% (-26.31,-10.39), P<0.00001] and transcutaneous electrical acupoint stimulation (TEAS) [MD=-5.17, 95% (-9.59,-0.74), P=0.02] could promote the recovery of gastrointestinal function after surgery.For postoperative colorectal cancer patients, electroacupuncture [MD=-15.17, 95% (-28.81,-1.54), P<0.05], manual acupuncture [MD=-20.51, 95% (-39.19,-1.84), P<0.05], warm needling [MD=-18.55, 95% (-23.86,-13.24), P<0.05], ear acupressure [MD=-5.38, 95% (-9.80,-0.97), P<0.05], acupoint application [MD=-26.30, 95% (-32.81,-19.79), P<0.05], ear acupressure+acupressure [MD=-9.67, 95% (-13.58,-5.76), P<0.05], ear acupressure+manual acupuncture [MD=-18.70, 95% (-21.01,-16.39), P<0.05], ear acupressure+moxibustion [MD=-22.90, 95% (-30.10,-15.70), P<0.05], moxibustion+acupressure [MD=-14.77, 95% (-20.59,-8.95), P<0.05] improved postoperative gastrointestinal function. In addition, the efficacy of acupressure [MD=-12.00, 95% (-31.60,7.60), P>0.05] needed to be further demonstrated. Conclusion: Acupuncture therapy has a positive therapeutic impact on postoperative gastrointestinal dysfunction in gastric and colorectal cancers, but this finding should still be taken with caution.

A randomized phase 2 study of the 5-HT4 receptor agonist felcisetrag for postoperative gastrointestinal dysfunction after bowel surgery.

BACKGROUND: Felcisetrag (5-hydroxytryptamine-4 receptor [5-HT4] agonist) is under investigation as prophylaxis or active treatment for accelerating resolution of gastrointestinal function post-surgery. METHODS: Phase 2, randomized, placebo-controlled, parallel five-arm, double-blind, multicenter study (NCT03827655) in 209 adults undergoing open or laparoscopic-assisted bowel surgery. Patients received intravenous placebo, felcisetrag 0.1 mg/100 â€‹mL or 0.5 mg/100 â€‹mL pre-surgery only, or pre-surgery and daily post-surgery until return of gastrointestinal function or for up to 10 days. PRIMARY ENDPOINT: time to recovery of gastrointestinal function. RESULTS: Median time to recovery of gastrointestinal function was 2.6 days for both felcisetrag 0.5 â€‹mg daily and 0.5 â€‹mg pre-surgery versus 1.9 days for placebo (p â€‹> â€‹0.05). There were no notable differences in adverse events between treatment arms. CONCLUSIONS: Felcisetrag was well tolerated with no new safety concerns. However, no clinically meaningful difference in time to recovery of gastrointestinal function versus placebo was observed. Further investigation of the utility of 5-HT4 agonists in complicated, open abdominal surgeries may be warranted.

Validity of the I­FEED classification in assessing postoperative gastrointestinal impairment in patients undergoing elective lumbar spinal surgery with general anesthesia: a prospective observational study.

BACKGROUND: The I-FEED classification, scored 0-8, was reported to accurately describe the clinical manifestations of gastrointestinal impairment after colorectal surgery. Therefore, it is interesting to determine whether the I-FEED scoring system is also applicable to patients undergoing lumbar spine surgery. METHODS: Adult patients undergoing elective lumbar spine surgery were enrolled, and the I-FEED score was measured for 4 days after surgery. The I-FEED scoring system incorporates five elements: intake (score: 0, 1, 3), feeling nauseated (score: 0, 1, 3), emesis (score: 0, 1, 3), results of physical exam (score: 0, 1, 3), and duration of symptoms (score: 0, 1, 2). Daily I-FEED scores were summed, and the highest overall score is used to categorize patients into one of three categories: normal (0-2 points), postoperative gastrointestinal intolerance (POGI; 3-5 points), and postoperative gastrointestinal dysfunction (POGD; 6 + points). The construct validity hypothesis testing determines whether the I-FEED category is consistent with objective clinical findings relevant to gastrointestinal impairment, namely, the longer length of hospital stay (LOS), higher inhospital medical cost, more postoperative gastrointestinal medical treatment, and more postoperative non-gastrointestinal complications. RESULTS: A total of 156 patients were enrolled, and 25.0% of patients were categorized as normal, 49.4% POGI, and 25.6% POGD. Patients with higher I-FEED scores agreed with the four validity hypotheses. Patients with POGD had a significantly longer length of hospital stay (1 day longer median stay; p = 0.049) and more inhospital medical costs (approximately 500 Taiwanese dollars; p = 0.037), and more patients with POGD required rectal laxatives (10.3% vs. 32.5% vs. 32.5%; p = 0.026). In addition, more patients with POGD had non-gastrointestinal complications (5.1% vs. 11.7% vs. 30.0%; p = 0.034). CONCLUSION: This study contributes preliminary validity evidence for the I-FEED score as a measure for postoperative gastrointestinal impairment after elective lumbar spine surgery.

Acupuncture for postoperative gastrointestinal dysfunction in cancer: a systematic review and meta-analysis.

Background: Postoperative gastrointestinal dysfunction (PGD) in cancer is the commonest and most severe postoperative complication in patients with cancer. Acupuncture has been widely used for PGD in cancer. This study aimed to evaluate the efficacy and safety of acupuncture for PGD in cancer. Methods: We comprehensively searched eight randomised controlled trials (RCTs) of acupuncture for PGD in cancer published until November 2022. Time to first flatus (TFF) and time to first defecation (TFD) were the primary outcomes, and time to bowel sound recovery (TBSR) and the length of hospital stay (LOS) were the secondary outcomes. The Cochrane Collaboration Risk of Bias Tool was used to assess the quality of the RCTs, and the Grading of Recommendations Assessment, Development, and Evaluations (GRADE) system was used to evaluate the certainty of the evidence. The meta-analysis was performed using RevMan 5.4, and a publication bias test was performed using Stata 15.1. Results: Sixteen RCTs involving 877 participants were included in this study. The meta-analysis indicated that acupuncture could effectively reduce the TFF, TFD, and TBSR compared with routine treatment (RT), sham acupuncture, and enhanced recovery after surgery (ERAS). However, acupuncture did not shorten the LOS compared with RT and ERAS. The subgroup analysis revealed that acupuncture could significantly reduce the TFF and TFD. Acupuncture effectively reduced the TFF and TFD in all cancer types included in this review. Besides, local acupoints in combination with distal acupoints could reduce the TFF and TFD, and distal-proximal acupoints could significantly reduce the TFD. No trial reported adverse events of acupuncture. Conclusions: Acupuncture is an effective and relatively safe modality for treating PGD in cancer. We anticipate that there will be more high-quality RCTs involving more acupuncture techniques and cancer types, focusing on combining acupoints for PGD in cancer, further determining the effectiveness and safety of acupuncture for PGD in patients with cancer outside China.

[Effect of thumb-tack needle on gastrointestinal function recovery after cesarean section under the concept of enhanced recovery after surgery].

OBJECTIVE: To observe the synergistic effect and safety of combined use of houpo paiqi mixture and thumb-tack needle on promoting gastrointestinal function recovery after cesarean section. METHODS: Parturients receiving cesarean section were randomly divided into the control group (29 cases), the traditional Chinese medicine (TCM) group (30 cases) and needle+TCM group (30 cases). The control group received only routine postoperative treatment. Besides the treatment as the control group, parturients in the TCM group were given 50 mL houpo paiqi mixture 6 h and 10 h after cesarean section respectively. Besides the treatment as the TCM group, parturients in the needle+TCM group received thumb-tack needle treatment at bilateral Zusanli(ST36), Tianshu(ST25), Shangjuxu(ST37) and Sanyinjiao(SP6), Zhongwan(CV12), Qihai(CV6), with auricular pressure at bilateral otopoints Zigong(Uterus), Wei(Stomach) and Dachang(Large intestine), within 1 h after the parturients returned to the ward after the operation. Each acupoint was pressed for 10 s and performed acupressure every 4 h (except sleeping hours), continuously for 3 d. The time of bowel sound recovery, the time to the first postoperative exhaust and defecation, the time of postoperative semi-fluid diet recovery, incidence of postoperative nausea and vomiting (PONV) and abdominal distention, and abdominal pain VAS score were recorded and analyzed. The safety of the treatments was also evaluated. RESULTS: Compared with the control group, the time of bowel sounds recovery, the time to the first postoperative exhaust and the time of postoperative semi-fluid diet recovery were significantly shortened in the TCM and needle+TCM groups (P<0.01); the time to the first postoperative defecation were significantly shortened (P<0.01), incidence of both abdominal distention and PONV were significantly decreased in the needle+TCM group (P<0.05, P<0.01); incidence of abdominal distention were significantly decreased in TCM group (P<0.05). Compared with the TCM group, the time of bowel sounds recovery, the time to the first postoperative exhaust and defecation, and the time of postoperative semi-fluid diet recovery were significantly shortened (P<0.01), and incidence of both abdominal distention and PONV were significantly decreased in the needle+TCM group (P<0.05). VAS scores of the three groups decreased gradually over time (P<0.01). Compared with the control and TCM groups, VAS scores of the needle+TCM group significantly decreased at 24 h, 48 h and 72 h after operation (P<0.01). No treatment-related adverse reactions were observed during the whole trial. CONCLUSION: On the base of the treatment with houpo paiqi mixture, the addition of thumb-tack needle treatment exerted positive synergistic effect on gastrointestinal function recovery after cesarean section, with high safety, which is worthy of clinical application.

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.

Incidence and risk factors for postoperative gastrointestinal dysfunction occurrence after gastrointestinal procedures in US patients.

BACKGROUND: Incidence of, and potential risk factors for, postoperative gastrointestinal dysfunction (POGD) after gastrointestinal procedures performed in US hospitals were examined. METHODS: This retrospective study used hospital discharge data of inpatients who underwent ≥1 gastrointestinal procedures from 1-Jan-2016 to 30-Apr-2019. POGD incidence was calculated based on all hospitalizations for MDC-06 procedures. Predictors of POGD were assessed using multivariable logistic regression. RESULTS: POGD incidence was 5.8% among 638 611 inpatient hospitalizations. Major bowel procedures, peritoneal adhesiolysis, and appendectomy were the most notable predictors of POGD among gastrointestinal procedures assessed (adjusted odds ratios [95% confidence intervals]: 2.71 [2.59-2.83], 2.48 [2.34-2.64], and 2.15 [2.03-2.27], respectively; all p < 0.05). Procedures performed by colorectal/gastroenterology specialists (0.86 [0.84-0.89]), and those performed percutaneously (0.55 [0.54-0.56]) were associated with significantly lower odds of POGD (both P < 0.05). CONCLUSIONS: Findings may help clinicians tailor management plans targeting patients at high-risk of POGD.

[Progress on the researches of acupuncture preconditioning before surgery].

This paper reviews the researches on acupuncture preconditioning before surgery in recent years and explores its application value from three aspects, i.e. relieving preoperative anxiety, preventing from postoperative cognitive dysfunction, and preventing from postoperative gastrointestinal dysfunction. As a relatively safe non-drug treatment, acupuncture has the underlying advantages in participating into multidisciplinary coordination in the enhanced recovery after surgery (ERAS). By building up higher-quality medical evidences and revealing the effect mechanism of acupuncture from multi-dimenisonal aspects, it is expected that acupuncture technology can be coordinated with ERAS to optimize the clinical path in the perioperative period, and boost the development of the perioperative medicine ultimately.

The Effect of Hepatic Impairment on the Pharmacokinetics of Intravenously Administered Felcisetrag (TAK-954).

Felcisetrag (formerly known as TAK-954) is a selective serotonin receptor agonist under investigation for use in patients with postoperative gastrointestinal dysfunction. The safety, tolerability, and pharmacokinetics (PK) of intravenous (i.v.) felcisetrag have been studied, but little is known about the effect of hepatic impairment on the PK of the drug. This phase 1, non-randomized, open-label study compared the PK of a single 60-minute i.v. infusion of felcisetrag between healthy individuals (n = 8) and patients with moderate (n = 10) or severe (n = 7) hepatic impairment. The primary study end points were the total and free maximum observed plasma concentration of felcisetrag at the end of infusion (Cmax ), area under the concentration-time curve (AUC) from time 0 to the time of the last quantifiable concentration (AUClast ), and AUC from time 0 to infinity (AUCinf ). Concentration-time profiles of felcisetrag were similarly shaped between groups but revealed lower concentrations of total plasma felcisetrag with increasing severity of hepatic impairment, whereas concentrations of free felcisetrag increased. The ratios of AUClast and AUCinf for patients with severe hepatic impairment were up to 29.3% lower for total felcisetrag and up to 29.2% higher for free felcisetrag than found in healthy individuals (P < .05). Infusions were well tolerated with no discontinuations, severe adverse events, or deaths during the study. Overall, the effect of hepatic impairment on exposure to felcisetrag was minimal, suggesting that dose adjustment may be unnecessary in patients with hepatic impairment.

Extra Loading Dose of Dexmedetomidine Enhances Intestinal Function Recovery After Colorectal Resection: A Retrospective Cohort Study.

Importance: Postoperative gastrointestinal dysfunction (POGD) may be caused by postoperative vagus nerve tension inhibition and systemic inflammation. Dexmedetomidine (Dex) increases vagus nerve tone and affords an anti-inflammatory property, which may play a role in pathogenesis. Objective: To investigate whether a higher dose of Dex enhances gastrointestinal function recovery. Design: In this retrospective study, patients receiving colorectal surgery at the First Affiliated Hospital of Xi'an Jiaotong University from 2017 to 2019 were included. We evaluated the postoperative flatus time between recipients who received loading plus maintenance dose of DEX (LMD group, 237 recipients) and those who recieved maintenance dose of DEX (MD group, 302 recipients). Data were analyzed by logical regression and stratified and interaction analyses. The simulated pharmacokinetics of two DEX regimens was compared using the Tivatrainer software. Thirty paired blood samples from patients whose propensity scores matched with POGD-related factors at 24 h postoperatively were randomly selected, and their tumor necrosis factor-α (TNF-α), cyclooxygenase-2 (COX-2), d-lactate (DLA), acetylcholine (Ach), interleukin (IL)-10, lipopolysaccharide (LPS), IL-6, and inducible nitric oxide synthase (iNOS) levels were measured. Setting: Operating rooms and general surgery wards. Participants: Among the 644 patients undergoing colorectal surgery, 12 who had a colostomy, 26 without Dex infusion, 20 whose Dex administration mode cannot be classified, and 47 with a history of intestinal surgery were excluded. A total of 539 patients were included. Result: Compared with the MD group, the LMD group had a shorter recovery time to flatus; lower incidences of nausea, vomiting, abdominal distension, and abdominal pain (p < 0.05); and a slightly decreased heart rate. The LMD group was the independent factor of POGD (OR = 0.59, 95% CI = 0.41-0.87, p = 0.007) without being reversed in stratified and interaction analyses and had higher Dex plasma concentration from skin incision to 8 h postoperatively. The LMD group had a 39% and 43% increase in Ach and IL-10 levels, respectively, and a 33%-77% decrease in TNF-α, IL-6, COX-2, iNOS, LPS, and DLA levels (p < 0.05). Conclusion: Adding an extra loading dose of Dex can increase parasympathetic tone and decrease inflammation; hence, it can enhance postoperative gastrointestinal function recovery following colorectal surgery.

Management of postoperative nausea and vomiting in the context of an Enhanced Recovery after Surgery program.

The concept of Enhanced Recovery after Surgery (ERAS) emerged at the turn of the millennium and quickly gained footing worldwide leading to the establishment of institutional ERAS protocols and subspecialty guidelines. While the use of postoperative nausea and vomiting (PONV) prophylaxis predates ERAS by a significant extent, the emergence of ERAS amplified the importance of antiemetic prophylaxis in perioperative care and drew attention to the truly multifactorial nature of postoperative gastrointestinal dysfunction. The following discussion will review key paradigms behind PONV prophylaxis and ERAS, highlight the interrelationship between these two endeavors, and then explore subspecialty ERAS guidelines that uniquely influence PONV prophylaxis. Attention will center on the ERAS Society guidelines (ESGs) as the primary representative of current ERAS practice, though many deviations from the guidelines exist within the literature and institutional practices.

Postoperative quality of life and dysfunction in patients after combined total gastrectomy and esophagectomy.

BACKGROUND: Patients with esophageal cancer and a history of gastrectomy or concurrent gastric cancer undergo not only esophagectomy but also total gastrectomy. The goal of this study is to evaluate the postoperative quality of life (QOL) and dysfunction of these patients using two postoperative questionnaires. MATERIALS AND METHODS: From 1999 to 2015, 41 patients underwent concurrent esophagectomy and total gastrectomy. A jejunal pedicle with the subcutaneous supercharge technique was used for reconstruction. Patients were divided into two groups, including those undergoing concurrent esophagostomy and gastrectomy (Group 1), and those undergoing esophagectomy alone (Group 2, history of previous gastrectomy). Patients were analyzed by time interval, including patients within three years of surgery (Group A) and those more than three years after surgery (Group B). RESULTS: Eighteen patients completed the questionnaires. The mean DAUGS20 score was 26.4 ± 13.2. The DAUGS20 scores of groups 1 (N = 7) and 2 (N = 11) were 25.4 ± 12.5 and 27 ± 15.4 (p = 0.58), respectively. Global health status scored by the EORTC QLQC-30 were 71.4 ± 18.5 in group 1 and 67.4 ± 22.8 in group 2 (p = 0.85). DAUGS20 scores of group A (N = 10) and B (N = 8) were 28.1 ± 12.4 and 23.3 ± 14.4 (p = 0.35). No significant differences were found between groups A and B regarding the QLQ-C30 scores. CONCLUSION: DAUGS20 and QLQ-C30 scores showed no significant differences between groups 1 and 2 or groups A and B. These results suggest that postoperative QOL and dysfunction may be influenced more by current status than by surgical history and postoperative interval. Previous reports describe a DAUGS 20 score after gastrectomy of 27.8 and after esophagectomy of 36.1. The DAUGS20 score of these 18 patients is lower than DAUGS20 scores for patients undergoing either operation alone. Reconstruction using a subcutaneously placed jejunal segment seems to be reasonable.

Efficacy and safety of the "Xingnao Kaiqiao" acupuncture technique via intradermal needling to treat postoperative gastrointestinal dysfunction of laparoscopic surgery: study protocol for a randomized controlled trial.

BACKGROUND: Xingnao Kaiqiao acupuncture involves needling of the Neiguan (PC6), Renzhong (DU26), and Sanyinjiao (SP6) acupoints. The technique has a significant clinical effect in many neurological diseases. In the present report, we have developed a protocol for a scientific trial to analyze whether Xingnao Kaiqiao can be used to treat gastrointestinal dysfunction after laparoscopic surgery. In this context, we intend to execute a double-blind, randomized controlled trial to assess the efficacy and safety of Xingnao Kaiqiao acupuncture via intradermal needling. METHODS/DESIGN: This will be a single-center, double-blind, randomized controlled clinical trial. It has been designed on the basis of the Consolidated Standards of Reporting Trials (CONSORT 2010) guidelines and the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). The subjects will be recruited from among inpatients scheduled for laparoscopic surgery at the Department of Minimally Invasive Surgery, Tianjin Nankai Hospital, Tianjin, China. Using random numbers generated in SPSS 19.0, the recruited subjects will be allocated to either the "Xingnao Kaiqiao" group or the sham stimulation group. A specially appointed investigator will be in charge of the randomization. Xingnao Kaiqiao via intradermal needling (or sham needling) will be administered 6 h after laparoscopic surgery, and then every 12 h for a total of six sessions, each of which will last 3 min. The subjects will undergo their first evaluation shortly before the first treatment (6 h after laparoscopic surgery); evaluations will be repeated every 12 h until a total of seven evaluations have been completed. The primary outcome will be the time until the first postoperative flatus. The secondary outcomes will be: the time until the first postoperative defecation; levels of abdominal pain, abdominal distension, and nausea; blood ghrelin level; occurrence of vomiting; psychological status; and quality of life. DISCUSSION: This upcoming randomized clinical trial was designed as a standardized method to assess the efficacy and safety of Xingnao Kaiqiao acupuncture using intradermal needles on PC6, DU26, and SP6 in the treatment of gastrointestinal dysfunction after laparoscopic surgery. We aim to provide evidence and thus improve the clinical application of this technique. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR-IOR-17010763 . Registered on 2 March 2017.

[Clinical observation of gastrointestinal dysfunction after vascular surgery prevented by electroacupuncture].

OBJECTIVE: To evaluate the preventative efficacy of preoperative electroacupuncture(EA) for gastrointestinal dysfunction after vascular surgery. METHODS: Sixty patients with the same general anesthesia before vascular surgery were randomly assigned to an observation group and a control group,30 cases in each one. In the observation group,acupuncture was used at bilateral Neiguan(PC 6),Zusanli(ST 36) and Shangjuxu(ST 37) in the forenoon and afternoon one day before surgery,with EA(continuous wave,15 Hz) at Zusanli(ST 36) and Shangjuxu(ST 37) for 20 min. The abdominal distension rate and degree as well as the length of stay in hospital after surgery were recorded. RESULTS: There was no statistic difference about the rate of abdominal distension between the two groups[16.7%(5/30) vs 36.7%(11/30),P>0.05)],but it was lighter in the observation group 72 hours after surgery(P<0.05). The length of stay in hospital in the observation group was shorter than that in the control group[(5.33±1.30) d vs (7.33±1.71) d,P<0.05]. CONCLUSIONS: Acupuncture at Neiguan(PC 6),Zusanli(ST 36) and Shangjuxu(ST 37) one day before surgery can improve gastrointestinal function after vascular surgery with general anesthesia,and it has some efficacy as to shorting the length of stay in hospital.
