RÉSUMÉ

Objective:To evaluate the effect of sacral nerve stimulation (SNS) for STC by receptor tyrosine kinase c-kit.Methods:Wistar rats were fed with diphenoxylate to make slow transit constipation(STC) rat model.Sacral nerve stimulation(SNS) for the SNS Rat Group.The studied animals were allocated into three experimental groups:STC Rat Group;SNS Rat Group;Normal Rat Group;Every group included 10 rats.The c-kit of ICC in the subserosal layer of rats were analyzed by immunohistochemistry,western blot and RT-PCR.Results:The morphological characteristics of STC Rat Group were not comparable to those of the multipolar c-Kit positive ICC seen in the subserosa of colon of normal rat.In the colon of rat,c-kit protein and c-kit gene in SNS rat group and Normal rat group was significantly higher than STC rat group detecting by western blot.Statistical differences between STC Group and SNS Rat Group were found (P<0.05);statistical differences between STC Group and Normal Rat Group were also found (P<0.05).There was not statistical differences between SNS rat group and Normal Rat Group.Conclusion:SNS has effective treatment for the STC rat.

RÉSUMÉ

Objective To discuss the relativity of dyschesia with the change of puborectalismuscle.Methods 68 patients with dyschesia were compared with 68 healthy volunteers at lithotomy position undergoing 3D ultrasonography on resting,contracting and maximum exertion phase respectively.Three dimensionally reconstructed images were reconstructed and pubo-rectal angle and the thickness of puborectalis muscle at 6 o'clock position were measured.Results The pubo-rectal angle of the study group and control group had no significant differences at either resting [(86 ± 8) ° vs.(86 ± 8)°] or contracting phases [(88 ± 9) ° vs.(86 ± 7) °] (t =-0.145,t =0.434,P > 0.05).While at maximum exertion the differences were significant [(80 ± 6) °vs.(95 ± 5) °,t =-5.397,P < 0.05].The d-value of pubo-rectal angle between maximum and resting exertion statistically different [(6 ± 3) °,(-9 ± 7) °,t =5.551,P < 0.05].The thickness of puborectalis muscle between the two groups differed statistically significant only at maximum exertion phase [(4.60 ± 0.60) mm vs.(3.97 ± 0.32) mm,t =6.872,P < 0.05].The d-value of the thickness of puborectalis muscle between maximum and resting exertion were statistically different (t =-11.474,P < 0.05).Conclusions The pubo-rectal angle of the study group is smaller at maximum exertion than the control group.The thickness of puborectalis muscle at six o'clock (lithotomy position) in study group is larger at maximum exertion than the control group.And the severity of constipation changed with the variation of angle.

RÉSUMÉ

Objective To explore the effect of multiple positioning procedure for prolapse and hemorrhoids (PPH) in treatment of connective tissue type mixed hemorrhoids,and compare the results between PPH and Milligan-Morgan surgery.Methods One hundred and sixteen patients with connective tissue type mixed hemorrhoids were divided into treatment group (62 cases) and control group (54 cases)according to random digits table method.The patients in treatment group received multiple positioning PPH,and the patients in control group received Milligan-Morgan surgery.The operative time,intraoperative blood loss,postoperative pain score,anal margin edema,wound healing time,perianal scar,anorectal stenosis,anal discharge and anorectal resting pressure were evaluated and compared between 2 groups.Results The operative time and intraoperative blood loss in treatment group were significantly lower than those in control group:(15.0 ± 2.3) min vs.(35.0 ± 3.4) min and (5.0 ± 2.1) ml vs.(15.0 ± 3.2) ml,and there were statistical differences (P < 0.05).The postoperative pain score and wound healing time in treatment group were significantly lower than those in control group:(4.83 ± 0.62) scores vs.(7.82 ± 0.37) scores and (8.2 ± 2.6) d vs.(17.4 ± 3.8) d,the rates of anal margin edema,perianal scar and anorectal stenosis in treatment group were significantly lower than those in control group:8.1% (5/62) vs.37.0% (20/54),0 vs.29.6% (16/54) and 1.6%(1/62) vs.16.7% (9/54),and there were statistical differences (P < 0.05 or < 0.01).The postoperative anorectal resting pressure was significantly lower than preoperative in control group:(13.80 ± 4.20) kPa vs.(17.20 ± 5.87) kPa,and there was statistical difference (P< 0.05).One patient (1.6%,1/62) in treatment group occurred anal discharge,and 10 patients (18.5%,10/54) occurred anal discharge in control group.The rate of anal discharge in treatment group was significantly lower than that in control group,and there was statistical difference (P < 0.01).Conclusions Multiple positioning PPH is effective for the treatment of connective tissue type mixed hemorrhoids.It improves the controllability of the amount of removal and the excision site.It decreases the incidence of anal margin edema,perianal scar and anal discharge scar,which provides an effective protection for the anal function.

RÉSUMÉ

Anorectal diseases pose significant impact on patients' physical and mental health. Specially, the living standard of the people is significantly reduced by fecal incontinence, constipation and anorectal pain. Meanwhile there is no radical treatment for these diseases. But sacral nerve stimulation (SNS) provides us with new ideas and methods to treat these diseases and achieves good curative effect. In this article, we review the current application of SNS.
