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.

Evaluating the clinical application and effect of acupuncture therapy in anal function rehabilitation after low-tension rectal cancer surgery

BACKGROUND According to the indexes of serum and anal function,acupuncture therapy was applied to patients with low rectal cancer in order to avoid the occurrence of anal incontinence and reduce complications.AIM To explore the clinical application and evaluate the effect of acupuncture therapy for anal function rehabilitation after low-tension rectal cancer surgery.METHODS From the anorectal surgery cases,we selected 120 patients who underwent colorectal cancer surgery between January 2020 and December 2022 and randomly divided them into a control group(n=60),observation group(n=60),and control group after surgery for lifestyle intervention(including smoking cessation and exercise),dietary factor adjustment,anal movement,and oral loperamide treatment.The serum levels of motilin,5-hydroxytryptamine,and vasoactive intestinal peptide(VIP),Wexner score for anal incontinence,and incidence of complications were compared between groups.RESULTS After treatment,the VIP and 5-hydroxytryptamine levels in the observation group were lower than those in the control group(P<0.05).The motilin level was higher than that in the control group(P<0.05).Postoperative anal incontinence was better in the observation group than in the control group(P<0.05).The incidence of complications in the observation group was 6.67%,which was significantly lower than that in the control group(21.67%;P<0.05).CONCLUSION Acupuncture therapy has a positive effect on the rehabilitation of anal function after low-tension rectal cancer surgery;it can effectively help to improve the serum indices of patients,avoid the occurrence of anal incontinence,and reduce the incidence of complications.Popularizing and applying it will be valuable.

Analysis of the impact of ERAS-based respiratory function training on older patients’ability to prevent pulmonary complications after abdominal surgery

BACKGROUND In China,as the population grows older,the number of elderly people who have died from respiratory problems has increased.AIM To investigate whether enhanced recovery after surgery(ERAS)-based respiratory function training may help older patients who had abdominal surgery suffer fewer pulmonary problems,shorter hospital stays,and improved lung function.METHODS The data of 231 elderly individuals having abdominal surgery was retrospectively analyzed.Based on whether ERAS-based respiratory function training was provided,patients were divided into ERAS group(n=112)and control group(n=119).Deep vein thrombosis(DVT),pulmonary embolism(PE),and respiratory tract infection(RTI)were the primary outcome variables.Secondary outcome variables included the Borg score Scale,FEV1/FVC and postoperative hospital stay.RESULTS The percentage of 18.75%of ERAS group participants and 34.45%of control group participants,respectively,had respiratory infections(P=0.007).None of the individuals experienced PE or DVT.The ERAS group’s median postoperative hospital stay was 9.5 d(3-21 d)whereas the control groups was 11 d(4-18 d)(P=0.028).The Borg score decreased on the 4th d following surgery in the ERAS group compared to the 2nd d prior(P=0.003).The incidence of RTIs was greater in the control group than in the ERAS group among patients who spent more than 2 d in the hospital before surgery(P=0.029).CONCLUSION ERAS-based respiratory function training may reduce the risk of pulmonary complications in older individuals undergoing abdominal surgery.

Resective surgery for liver tumor: a multivariate analysis of causes and risk factors linked to postoperative complications

BACKGROUND: In spite of accurate selection of patients eligible for resection, and although advances in surgical techniques and perioperative management have greatly contributed to reducing the rate of perioperative deaths, stress must be placed on reducing the postoperative complication rates reported to be still as high as 50%. This study was designed to analyze the causes and foreseeable risk factors linked to postoperative morbidity on the grounds of data derived from a single-center surgical population. METHODS: From September 1989 to March 2005, 287 consecutive patients, affected either with HCC or liver metastasis, had liver resection at our department. Among the HCC series we recorded 98 patients (73.2%) in Child- Pugh class A, 32 (23.8%) in class B and 4 in class C (3%). In 104 colorectal metastases, 71% were due to colon cancer, 25% rectal, 3% sigmoid, and 1% anorectal. In 49 non-colorectal metastases, 22.4% were derived from breast cancer, 63.2% gastrointestinal tumors (excluding colon) and 14.4% other cancers. We performed 80 wedge resections, 77 bisegmentectomies and/or left lobectomies, 74 segmentectomies, 22 major hepatectomies, 20 left hepatectomies, and 14 trisegmentectomies. RESULTS: The in-hospital mortality rate in this series was 4.5%, and the morbidity rate was 47.7%, because of pleural effusion (30%), hepatic abscess (25%), hepatic insufficiency (19%), ascites (10%), hemoperitoneum (10%), or biliary fistula (6%). The variables associated with the technical aspects of the surgical procedure thatwere responsible for the complications were: a Pringle maneuver length more than 20 minutes (P=0.001); the type of liver resection procedure, including major hepatectomy (P=0.02), left hepatectomy (P=0.04), trisegmentectomy (P=0.04), bisegmentectomy and/or left lobectomy (P=0,04); and a blood transfusion of more than 600 ml (P=0.04). CONCLUSION: The evaluation of causes and foreseeable risk factors linked to postoperative morbidity during the planning of surgical treatment should play the same role as other factors weighed in the selection of patients eligible for liver resection.

Effects of endoscopic surgery via different approaches on neurological function and complications in patients with hypertensive cerebral hemorrhage

Objective:To study the effects of different approaches of neuroendoscopic treatment on neurological function and complications of patients with hypertensive cerebral hemorrhage.Methods:72 patients with hypertensive cerebral hemorrhage diagnosed and treated in our hospital were selected as research objects.They were divided into the study group(n=37)and the control group(n=35)according to different approaches.The study group was the lateral fissure approach,and the control group was the anterior coronary suture approach.The curative effect,hematoma clearance,postoperative wake time,postoperative cerebral edema,daily living ability,neurological function,and complications in the two groups were observed.Results:The efficacy of the study group was higher than that of the control group,and the differences were statistically significant(P<0.05).The postoperative cerebral edema,postoperative wake time,and postoperative intracranial pressure in the study group were lower than those in the control group,and the hematoma clearance rate in the study group was higher than that in the control group,the differences were statistically significant(P<0.05);At 3 and 6 months after treatment,the daily living ability of the study group was higher than that of the control group,and neurological dysfunction of the study group was lower than that of the control group(P<0.05);The complication rate of the study group was lower than that of the control group(P<0.05);There was no significant difference in mortality rate between the two groups(P>0.05).Conclusion:Different approaches have different effects on patients with hypertensive intracerebral hemorrhage.Compared with the anterior coronary suture approach,the lateral fissure approach has less damage to nerve function,and has less postoperative complications.

Preoperative Exercise Testing Is a Better Predictor of Postoperative Complications than Pulmonary Function Testing for Patients with Lung Cancer

Objective: The aim of this preliminary study was to evaluate the feasibility of exercise testing (ET) for predicting postoperative complications in patients with impaired pulmonary function. Methods: Thirteen patients were prospectively enrolled. The enrollment criteria were FEV1.0% 8 by the Goddard classification or interstitial pneumonia on chest computed tomography. Patients underwent testing for pulmonary function, six-minute walking test (6MWT), and stair-climbing test (SCT). Postoperative cardiopulmonary complications (PCPCs) were recorded. Results: Four patients developed PCPCs. There were no significant differences between the patients with PCPCs (n = 4) and those without PCPCs (n = 9) for background data and PFT. The distances achieved in the 6MWT were 503 ± 72.7 m for patients without PCPCs and 369 ± 50.7 m for patients with PCPCs (p = 0.011). The SCT climbing heights were 20.4 ± 5.3 m for patients without PCPCs and 14.9 ± 4.0 m for patients with PCPCs (P = 0.187). Cut-off points, including a 6MFT distance of less than 400 m, SCT height lower than 15 m, and SCT climbing speed less than 8.5 m/min, were predictive of CPCP. Conclusions: Exercise testing is more feasible for predicting postoperative cardiopulmonary complications than stationary pulmonary function testing.

Hepatic encephalopathy before and neurological complications after liver transplantation have no impact on the employment status 1 year after transplantation

To investigate the impact of hepatic encephalopathy before orthotopic liver transplantation (OLT) and neurological complications after OLT on employment after OLT. METHODSOne hundred and fourteen patients with chronic liver disease aged 18-60 years underwent neurological examination to identify neurological complications, neuropsychological tests comprising the PSE-Syndrome-Test yielding the psychometric hepatic encephalopathy score, the critical flicker frequency and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), completed a questionnaire concerning their occupation and filled in the short form 36 (SF-36) to assess health-related quality of life before OLT and 12 mo after OLT, if possible. Sixty-eight (59.6%) patients were recruited before OLT, while on the waiting list for OLT at Hannover Medical School [age: 48.7 ± 10.2 years, 45 (66.2%) male], and 46 (40.4%) patients were included directly after OLT. RESULTSBefore OLT 43.0% of the patients were employed. The patients not employed before OLT were more often non-academics (employed: Academic/non-academic 16 (34.0%)/31 vs not employed 10 (17.6%)/52, P = 0.04), had more frequently a history of hepatic encephalopathy (HE) (yes/no; employed 15 (30.6%)/34 vs not employed 32 (49.2%)/33, P = 0.05) and achieved worse results in psychometric tests (RBANS sum score mean ± SD employed 472.1 ± 44.5 vs not employed 443.1 ± 56.7, P = 0.04) than those employed. Ten patients (18.2%), who were not employed before OLT, resumed work afterwards. The patients employed after OLT were younger [age median (range, min-max) employed 47 (42, 18-60) vs not employed 50 (31, 29-60), P = 0.01], achieved better results in the psychometric tests (RBANS sum score mean ± SD employed 490.7 ± 48.2 vs not employed 461.0 ± 54.5, P = 0.02) and had a higher health-related quality of life (SF 36 sum score mean ± SD employed 627.0 ± 138.1 vs not employed 433.7 ± 160.8; P < 0.001) compared to patients not employed after OLT. Employment before OLT (P < 0.001), age (P < 0.01) and SF-36 sum score 12 mo after OLT (P < 0.01) but not HE before OLT or neurological complications after OLT were independent predictors of the employment status after OLT. CONCLUSIONHE before and neurological complications after OLT have no impact on the employment status 12 mo after OLT. Instead younger age and employment before OLT predict employment one year after OLT.

Role for contrast-enhanced ultrasound in assessing complications after kidney transplant

Kidney transplantation(KT)is an effective treatment for end-stage renal disease.Despite their rate has reduced over time,post-transplant complications still represent a major clinical problem because of the associated risk of graft failure and loss.Thus,post-KT complications should be diagnosed and treated promptly.Imaging plays a pivotal role in this setting.Grayscale ultrasound(US)with color Doppler analysis is the first-line imaging modality for assessing complications,although many findings lack specificity.When performed by experienced operators,contrast-enhanced US(CEUS)has been advocated as a safe and fast tool to improve the accuracy of US.Also,when performing CEUS there is potentially no need for further imaging,such as contrast-enhanced computed tomography or magnetic resonance imaging,which are often contraindicated in recipients with impaired renal function.This technique is also portable to patients’bedside,thus having the potential of maximizing the cost-effectiveness of the whole diagnostic process.Finally,the use of blood-pool contrast agents allows translating information on graft microvasculature into time-intensity curves,and in turn quantitative perfusion indexes.Quantitative analysis is under evaluation as a tool to diagnose rejection or other causes of graft dysfunction.In this paper,we review and illustrate the indications to CEUS in the post-KT setting,as well as the main CEUS findings that can help establishing the diagnosis and planning the most adequate treatment.

High complex anal fistula managed by the modified transanal opening of the intersphincteric space via the inter-sphincteric approach:A case report

BACKGROUND High complex anal fistulas are epithelialized tunnels,with the main fistula piercing above the deep external sphincter and the internal opening approaching the dentate line.Conventional surgical procedures for high complex anal fistulas remove most of the external sphincter and damage the anorectal ring.Postoperative loss of anal function can cause physical and mental damage.Transanal opening of the intersphincteric space(TROPIS)is an effective procedure that completely preserves the external anal sphincter.However,its clinical application is limited by challenges in the localization of the internal opening of a fistula and the high risk of complications.On the basis of our clinical experience,we modified the TROPIS procedure for the treatment of treating high complex anal fistulas.CASE SUMMARY A patient with a high complex anal fistula located above the anorectal ring underwent modified TROPIS,which involved sepsis drainage and identification of the internal opening in the intersphincteric space.The patient with the high complex anal fistula recovered well postoperatively,without any postoperative complications or anal dysfunction.Anal function returned to normal after 17 months of follow-up.CONCLUSION The modified TROPIS procedure is the most minimally invasive surgery for anal fistulas that minimally impairs anal function.It allows the complete removal of infected anal glands and reduces the risk of postoperative complications.Modified TROPIS via the intersphincteric approach is an alternative sphincter-preserving treatment for high complex anal fistulas.

Clinical effect of spleen aminopeptide on improving liver function damage and immune function in children with infant hepatitis syndrome

BACKGROUND Infant hepatitis syndrome(IHS)is a clinical syndrome in infants less than one year of age with generalized skin jaundice,abnormal liver function,and hepato-megaly due to various etiologies such as infection.AIM To investigate the effect of IHS patients,after treatment with arsphenamine-based peptides,on patients'liver function damage and immune function.METHODS Of 110 patients with IHS treated in our hospital from January 2019 to January 2021 were grouped according to the randomized residual grouping method,with 5 cases in each group shed due to transfer,etc.Ultimately,50 cases remained in each group.The control group was treated with reduced glutathione,and the treat-ment group was treated with sesquiterpene peptide based on the control group.Observe and compare the differences in indicators after treatment.RESULTS The comparison of serum total bilirubin,direct bilirubin,and serum alanine transferase after treatment was significantly different and lower in the treatment group than in the control group(P<0.05).The comparison of CD4+,CD3+,CD4+/CD8+after treatment was significantly different and higher in the treatment group than in the control group,and the comparison was statist-ically significant(P<0.05).The complication of the two groups showed that the rash,cough and sputum,elevated platelets,and gastrointestinal reactions in the treatment group were significantly lower than those in the control group,and the differences were statistically significant by test(P<0.05).CONCLUSION The comparative study of IHS treated with arsphenamine combined with reduced glutathione is more effective.

Effects of circumcision on male sexual functions： systematic review and meta-analysis

This meta-analysis was performed to assess sexual functions following adult male circumcision. We searched the Cochrane Central Register of Controlled Trials, PUBMED, EMBASE, the Cochrane Database of Systematic Review and Web of Science from their inception until January 2013 to identify all eligible studies that reported on men＇s sexual function after circumcision. The Cochrane Collaboration＇s RevMan 5.2 software was employed for data analysis, and the fixed or the random effect model was selected depending on the proportion of heterogeneity. We identified 10 studies, which described a total of 9317 circumcised and 9423 uncircumcised men who were evaluated for the association of circumcision with male sexual function. There were no significant differences in sexual desire （odds ratio （OR）： 0.99; 95% confidence interval （CI）： 0.92-1.06）, dyspareunia （OR： 1.12; 95% Ch 0.52-2.44）, premature ejaculation （OR. 1.13; 95% Ch 0.83-1.54）, ejaculation latency time （OR： 1.33; 95% Ch 0.69-1.97）, erectile dysfunctions （OR： 0.90; 95% Ch 0.65-1.25） and orgasm difficulties （OR： 0.97; 95% Ch 0.83-1.13）. These findings suggest that circumcision is unlikely to adversely affect male sexual functions. However, these results should be evaluated in light of the low quality of the existing evidence and the significant heterogeneity across the various studies. Well-designed and prospective studies are required for a further understanding of this topic.

Anal Sphincter Function after Intersphincteric Resection for Low Rectal Cancer

Objective： To assess the anal sphincter function after intersphincteric resection for low rectal cancer by questionnaire and vectorial manometry. Methods： twenty five patients underwent intersphincteric resection, the controls contained 25 patients of rectal cancer who underwent low anterior resection and 25 healthy people. The therapeutic responses were evaluated using the Vaizey and Wexner scoring systems and vectorial manometry. Results： The Vaizey and Wexner scores after intersphincteric resection were significantly higher than those of low anterior resection controls at one month, but had no significant difference one year after. On the other hand, the indexes of vectorial manometry still had significant difference one year later. The indexes after intersphincteric resection could not reach the normal level. Conclusion： The anal sphincter function after intersphincteric resection is lower than that after low anterior resection in short term, although the long-term results can be accepted, it still can not reach the normal level.

Change in Deferring Time Correlate to Improved Female Sexual Function after Anal Sphincter Repair: A Prospective Study

Background: Many women suffer from sexual problems after anal sphincter tears due to obstetric trauma. Aim: The study aimed to assess changes in sexual function after anal sphincter repair. Methods: The study was a non-randomized prospective observational cohort study. Inclusion of the study was done at the University Hospital, Uppsala, Sweden, between 2002 and 2007. Thirty-nine consecutive female patients admitted for anal sphincter repair were invited to the study. Twenty patients accepted and were included, four were lost to follow up and one was unevaluable (due to the formation of a stoma) leaving a study group of 15 patients. The patients were assessed with questionnaires before surgery and at three and 12 months after surgery. Outcomes: Change in reported sexual activity and dyspareunia. Results: Before surgery, 12/15 patients reported that their sexual life was impaired due to anal incontinence. The corresponding figure at 12 months was 9/15 (p = 0.43). Three patients remained sexually inactive throughout the study, five patients increased their sexual activity and one had decreased activity. Out of the 12 who were active, four stated dyspareunia at baseline, and only one reported dyspareunia at 12 months. The mean Miller incontinence scores at baseline and 12 months were 10.1 and 8.7, respectively. The change in incontinence score did not differ between those with decreased, stable or increased sexual activity. However, there was a definite correlation (r = 0.54 - 0.60, p 0.05) between change in sexual function and deferring time for stool. Clinical Implications: Operative management of anal sphincter tears alone is not curative for sexual problems due to anal incontinence but can be a part of the treatment. Strengths and Limitations: The study is a prospective study of sexual function. The limitations are that the questionnaires were not validated due to lack of such questionnaires at the time of the study and that the study population is quite small. Conclusion: Patients with a sphincter injury and fecal incontinence often have an impaired sexual function. Increased deferring time for stools after surgery increases the likelihood of improved sexual function.

新型导向器用于经皮螺钉固定治疗舟状骨骨折

背景:舟状骨骨折是临床上常见的腕部骨折,主要采用经皮螺钉治疗,首先闭合复位骨折端,然后将空心加压螺钉精准置于舟状骨轴心并加压固定骨折端,能够促进骨折愈合,使腕关节获得良好功能。目的:评价一种新型克氏针导向器辅助经皮空心加压螺钉治疗舟状骨骨折的临床疗效。方法:回顾性分析2015年1月至2020年12月河北医科大学第三医院手外科收治的15例舟状骨骨折患者的临床资料。所有患者均采用新型导向器辅助经皮空心加压螺钉固定治疗。统计患者的骨折愈合时间、手术时间、透视次数、重返工作的时间及并发症。术后12个月采用改良Mayo腕关节评分对腕关节功能进行评估,测量患侧及健侧腕关节掌屈、背伸、尺偏、桡偏活动度及握力。结果与结论:所有患者均完成了12个月随访。术后X射线片示:空心压力螺钉位于舟状骨轴心位置。所有舟状骨骨折均获骨性愈合,平均愈合时间10.0周。手术平均历时55.7 min,术中平均透视次数10.9次,平均10.3周重返工作岗位。腕关节功能:优9例,良5例,可1例,优良率93.3%。患侧及健侧的腕关节掌屈、背伸、尺偏、桡偏活动度及握力相比较,差异无显著性意义(P>0.05)。所有患者均未发生伤口感染、骨折畸形愈合、螺钉松动及断裂等并发症。结果表明,应用新型导向器可以缩短手术时间,减少术中透视次数,提高螺钉精准度,缩短重返工作时间,腕关节功能恢复良好。该导向器使空心加压螺钉治疗舟状骨骨折手术更容易。
