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.

Excisional hemorrhoidal surgery and its effect on anal continence

AIM:To investigate the role of anal cushions in hemorrhoidectomy and its effect on anal continence of the patients.METHODS:Seventy-six consecutive patients(33 men and 43 women) with a mean age of 44 years were included.They underwent Milligan-Morgan hemorrhoidectomy because of symptomatic third-and fourth-degree hemorrhoids and failure in conservative treatment for years.Wexner score was recorded and liquid continence test was performed for each patient before and two months after operation using the techniques described in our previous work.The speed-constant rectal lavage apparatus was prepared in our laboratory.The device could output a pulsed and speed-constant saline stream with a high pressure,which is capable of overcoming any rectal resistance change.The patients were divided into three groups,group A(< 900 mL),group B(900-1200 mL) and group C(> 1200 mL) according to the results of the preoperative liquid continence test.RESULTS:All the patients completed the study.The average number of hemorrhoidal masses excised was 2.4.Most patients presented with hemorrhoidal symptoms for more than one year,including a mean duration of incontinence of 5.2 years.The most common symptoms before surgery were anal bleeding(n = 55),prolapsed lesion(n = 34),anal pain(n = 12) and constipation(n = 17).There were grade Ⅲ hemorrhoids in 39(51.3%) patients,and grade Ⅳ in 37(48.7%) patients according to Goligher classification.Five patients had experienced hemorrhoid surgery at least once.Compared with postoperative results,the retained volume in the preoperative liquid continence test was higher in 40 patients,lower in 27 patients,and similar in the other 9 patients.The overall preoperative retained volume in the liquid continence test was 1130.61 ± 78.35 mL,and postoperative volume was slightly decreased(991.27 ± 42.77 mL),but there was no significant difference(P = 0.057).Difference was significant in the test value before and after hemorrhoidectomy in group A(858.24 ± 32.01 mL vs 574.18 ± 60.28 mL,P = 0.011),but no obvious difference was noted in group B or group C.There was no significant difference in Wexner score before and after operation(1.68 ± 0.13 vs 2.10 ± 0.17,P = 0.064).By further stratified analysis,there was significant difference before and 2 months after operation in group A(2.71 ± 0.30 vs 3.58 ± 0.40,P = 0.003).In contrast,there were no significant differences in group B or group C(1.89 ± 0.15 vs 2.11 ± 0.19,P = 0.179;0.98 ± 0.11 vs 1.34 ± 0.19,P = 0.123).CONCLUSION:There is no difference in the continence status of patients before and after Milligan-Morgan hemorrhoidectomy.However,patients with preoperative compromised continence may have further deterioration of their continence,hence Milligan-Morgan hemorrhoidectomy should be avoided in such patients.
