经肛巨结肠根治术后患儿的肛肠功能评价

目的：经肛门巨结肠一期根治术近期效果好,但术后患儿的肛肠功能目前尚不十分清楚。该文旨在评估患儿术后的排便模式,结肠和肛门括约肌功能。方法：对58例经肛门巨结肠根治术后半年以上儿童进行随访,随访时间为15.8 月 (6～24 月)。并进行排便功能问卷调查、钡灌肠、结肠传输时间和肛门直肠测压检查。33例正常儿童作为对照。结果：大多数随访患儿排便正常,无任何临床症状。４例出现稀便便频,9例污便,5例便秘,3例小肠结肠炎。钡灌肠结果显示大多数随访患儿结肠形态恢复良好。全部病例术后直肠肛管角（度）较对照组显著开大,有症状组较无症状组显著开大。58例随访患儿的平均全胃肠、左半结肠和右半结肠传输时间较术前显著缩短,与对照组相比差异无显著性意义。直肠肛管反射5例阳性。便秘组的肛管最大静息压和最大收缩压明显高于无症状组和对照组。污便组向量容积和对称指数较对照组显著降低。便秘组对称指数显著高于对照组。结论：经肛门巨结肠根治术后大多数患儿排便功能、结肠功能和括约肌功能良好。少数病例排便功能障碍可能与术后乙状结肠曲减少或消失、“新直肠”储便功能代偿不全和拖出结肠致直肠肛管角开大、肛门括约肌痉挛失弛缓有关。［中国当代儿科杂志,2007,9（3）：188-192］     

经肛巨结肠根治术后肛肠功能评价

目的探讨经肛门巨结肠根治术后排便模式、结肠功能和肛门括约肌功能。方法对58例经肛门巨结肠根治术后半年以上儿童进行随访,并进行排便功能问卷调查、钡灌肠、结肠传输时间和肛门直肠测压检查,对其术后肛肠功能进行综合评价。结果58例接受随访的患儿中,4例(4/58)稀便、便频,9例(9/58)污便,5例(5/58)便秘,3例(3/58)小肠结肠炎;钡灌肠结果:结肠形态恢复良好,乙状结肠迂曲减少或消失,与切除肠段长短相关;全部病例术后直肠肛管角(°)较对照组显著开大(123.3±15.1vs79.0±11.6,P<0.01),有症状组又较无症状组显著开大(135.6±15.9vs111.0±14.3,P<0.05)。结肠传输时间(h):与对照组比较,有症状组显著缩短(25.2±5.6vs28.7±7.7,P<0.05。直肠肛管反射3例阳性,2例弱阳性;肛管最大压力(mmHg):便秘组的最大收缩压明显高于无症状组和对照组(211±36vs200±65,P<0.05;211±36vs190±38,P<0.05);向量容积(cm×cmHg2)和对称指数:污便组向量容积和对称指数较术前及对照组显著降低(381±109vs662±31,P<0.05;0.69±0.32vs0.70±0.07,P<0.05);便秘组对称指数与术前无显著差异,但显著高于对照组(0.74±0.02vs0.70±0.07,P<0.05)。结论经肛门巨结肠根治术后排便功能、结肠功能和括约肌功能多数良好。少数病例排便功能障碍可能与术后乙状结肠曲减少或消失、“新直肠”储便功能代偿不全和拖出结肠致直肠肛管角开大、肛门括约肌痉挛失迟缓有关。     

直肠粘膜及内括约肌切除对预防巨结肠根治术后肠炎的影响

目的探讨经肛门直肠粘膜及内括约肌切除对预防先天性巨结肠根治术后继发巨结肠性肠炎发生的作用。方法对89例先天性巨结肠患儿在根治术同时行经肛门直肠粘膜及内括约肌大部切除。结果本组89例术后获随访77例,随访时间3～26个月,仅2例患儿分别于术后4个月和6个月有一次肠炎病史,术后肠炎发生率为2.6%,比术前明显减少(P<0.01)。随手术后时间的延长,污便的发生率由27.3%下降至2.6%。肛门直肠测压结果显示:对照组肛管静息压力为27.9±9.6mmHg;先天性巨结肠患儿手术前的肛管静息压力为37.9±12.5mmHg,比对照组明显增高(P<0.05);手术后1个月,2个月,2个月和6个月肛管静息压力分别为20.2±6.4mmHg,21.4±8.8mmHg,22.8±10.4mmHg和24.8±9.9mmHg,手术后肛管静息压力比手术前明显减低(P<0.01),术后6个月内患儿的肛管静息压力有上升的趋势,与对照组差异不显著。结论 本研究结果表明经肛门直肠粘膜及内括约肌切除安全易行,可有效地预防术后肠炎的发生。     

先天性巨结肠及同源病患儿术后直肠肛管测压与分析

The choice of operative procedures for Hirschsprung's disease allied diseases in children

目的 对先天性巨结肠同源病的手术处理方式做探讨.方法 2008年1月至2010年12月45例巨结肠同源病行根治术,平均年龄(35.5±5)个月,其中节细胞减少症(HG)33例(有既往手术史4例,12.1％),肠神经元发育不良症(IND) 12例(有既往手术史4例,33.33％).所有患儿均在术后1、3、6及12个月进行随访,记录患儿术后排便功能并与术前结果相比较.结果 HG组33例中17例(52％)经开腹手术,16例(48％)腹腔镜辅助或经肛门拖出术.结肠切除范围:左半切除28例(84.8％),次全切除5例(15.2％);12例IND组全部经开腹手术,结肠左半切除4例(33.3％),次全切除8例(66.7％).术后随访:所有患儿便秘症状消失,无手术死亡及严重并发症发生.不同术式组中均有少数患儿持续存在污粪现象,1年期随访经肛门手术显著高于开腹手术(P＜0.05).出现术后污粪患儿施行肛管直肠测压术前肛管静息压(66.5±11.67) mmHg,术后3个月为(52.17±0.31)mmHg较术前明显下降,但至术后6个月～1年后测压为(58±5.7)mmHg,与术前相比均无显著差异.结论 同源病的手术应根据不同病理类型和临床情况选择手术方式:原发性HG病变可采用直接经肛门拖出或腹腔镜辅助游离术.既往曾经肛门直肠手术或年长、晚期患儿应采取保留肛管直肠括约肌形态和功能完整性的术式.IND患儿均需行根治性次全切除术,不主张采用简单的经肛门拖出术式而应采用盆腔内的低位吻合术式.经肛门或腹腔镜辅助经肛门拖出术式组1年期随访时污粪率要高于非拖出术组,左半切或次全切方式对术后是否污粪无影响.     

经肛门Soave巨结肠根治术后肛门功能与直肠肛管测压的研究

目的探讨经肛门Soave巨结肠根治术后患儿直肠肛管测压改变及排便控制情况。方法63例经肛门Soave巨结肠根治术患儿,术后平均随访3年(6个月～4.5年),对患儿大便控制能力、便秘发生情况及肛门直肠测压结果进行评价。结果获访47例,大便控制优15例,良26例,差6例。2例患儿有持续性便秘,8例曾出现肠炎。肛门直肠测压检查2例恢复直肠肛管抑制反射。47例随访患者的直肠静息压与正常对照组无显著性差别(P>0.05),但6例大便控制差的患者肛管高压区长度较正常对照组下降(P<0.05)。结论应用经肛门Soave巨结肠根治术治疗小儿巨结肠,术后可获得较好的排便控制功能。少数病例排便功能障碍可能与内括约肌功能受损有关,直肠肛管测压是重要的评估依据之一。     

The impact of abnormal anoerectal movement and sensation on defecation function in children with transanal one-stage endorectal pull-through procedure for Hirschsprung's disease

目的 直肠肛门运动与感觉功能发生改变会影响到排便功能.本文通过分析经肛巨结肠根治术后患儿直肠肛门动力与感觉功能的客观检测指标变化,探讨其在排便控便中的作用.方法 采用高分辨率多通道胃肠功能检测系统,对经肛巨结肠根治术后有排便障碍来院就诊或能定期来院复查的37例患儿的临床排便功能评分和直肠肛门测压结果进行回顾性分析.结果 62.1％临床排便和测压指标正常,10.8％恢复了直肠肛门抑制反射.有排便障碍症状患儿中16.2％直肠肛门动力异常,24.3％直肠感觉阈值有改变,部分病例直肠肛门动力与感觉异常同时存在.结论 大多数经肛巨结肠根治术后患儿排便功能良好,直肠肛门动力与感觉功能趋于正常,括约肌功能完好.少数排便功能障碍的原因可能与直肠肛门动力及感觉功能异常有关.     

开腹和非开腹先天性巨结肠根治术疗效比较

Long-term functional, manometric, and endosonographic evaluation of patients operated upon with the Duhamel technique

Long-term functional results, anal endosonography (AES), and anal canal manometry were recorded in 48 patients aged 10 to 24 years (median 18) operated upon with the Duhamel technique for Hirschsprung's disease; 60.4% had perfect fecal control, 31.3% occasional staining and/or gas incontinence, and 8.3% constant fecal soiling, and 10.4% complained of constipation. Compared to normals, the patients had significantly reduced anal canal resting and squeeze pressures. AES visualized scar tissue in both the internal and external anal sphincter.

Investigations for incontinence and constipation after surgery for Hirschsprung's disease in children

Surgery for Hirschsprung's disease is associated with high rate of morbidity, in the form of either constipation or incontinence or a combination of the two. This study investigates the mechanisms responsible for incontinence and/or constipation following the pull-through operation for Hirschsprung's disease. There were 19 children (15 boys and 4 girls), who at the time of study; 16 had undergone Duhamel, 1 Rehbein, and 2 Soave operation. We classified patients according to their symptoms into 3 groups: Group A was incontinent of faeces; Group B was constipated and incontinent of faeces, and Group C was constipated only. The median age at referral was 6 years, and the median period after operation was 5 years. All patients were investigated by intestinal transit study, endoanal sonography and anorectal manometry. Group A had normal or rapid transit study, as opposed to Groups B and C, who had delayed-transit study. On endoanal sonography, all children had an intact internal and an external anal sphincter, below the level of pull-through operation. The anorectal manometry showed a significantly lower resting anal pressure in the incontinent Group A as compared to the constipated children with or without incontinence in Group B or C (38 mmHg versus 57 or 66 mmHg respectively). The rectal pressure was also significantly higher in children in Group A as compared to those in Group B or C (71 mmHg versus 42 or 36 mmHg). The ratio of rectal/anal pressure was higher in incontinent children in Group A, as compared to constipated children in Group B or C. Therefore, constipation can be caused by high anal resting pressure and a weak rectal peristalsis, while faecal incontinence can be secondary to poor compliance and elevated rectal pressure in the presence of normal or low anal sphincter resting pressure. Aperients are the mainstay of treatment of constipation, however, children with incontinence are more difficult to treat. We did not attempt to define the pattern of nerve plexus because of poor results of revision operation for residual hypoganglionic segment and intestinal neuronal dysplasia. Treatment of these children can become more rational, if furnished with detailed functional studies. We advocate investigation of the anorectal function at an early stage in symptomatic children after surgery for Hirschsprung's disease, and less invasive treatment should be considered before embarking on major surgery.     

不同型别的功能性便秘患儿肛门直肠测压对照研究

目的探讨功能性便秘（FC）患儿与健康儿童肛门直肠动力学差异,为其临床分型诊断及治疗提供依据。方法采用功能性胃肠病罗马Ⅲ诊断标准,收集2008年1月至2009年1月在第四军医大学唐都医院儿科门诊及住院的FC患儿为FC组。选取同期无消化系统症状,平日排便正常的健康儿童为正常对照组。采用不透光X线硫酸钡条测定结肠传输指数（TI）,依据TI将FC组分为出口梗阻型（OOC）亚组、慢传输型（STC）亚组和混合型（MIX）亚组。通过肛门直肠测压法分析FC各亚组与正常对照组肛门直肠动力学差异。结果研究期间FC组纳入25例,其中STC亚组10例,OOC亚组15例,未发现MIX患儿;正常对照组纳入10名。FC组与正常对照组肛门括约肌静息压差异无统计学意义（P＞0.05）。STC亚组肛门括约肌最大收缩压与正常对照组差异无统计学意义（P＞0.05）,OOC亚组肛门括约肌最大收缩压显著高于正常对照组及STC亚组（P＜0.05）。FC组直肠最低敏感量及最大耐受量均显著高于正常对照组（P均＜0.05）。STC亚组与OOC亚组直肠最低敏感量及最大耐受量差异均无统计学意义（P均＞0.05）。结论FC患儿存在明显的肛门直肠动力和感觉异常;OOC和STC患儿的肛门直肠动力学存在差异。肛门直肠测压检查对协助诊断FC有一定价值。     

Is the anorectal sphincter damaged during a transanal endorectal pull-through (TERPT) for Hirschsprung's disease? A 3-dimensional, vector manometric investigation.

BACKGROUND/PURPOSE: The transanal endorectal pull-through technique (TERPT) for Hirschsprung's disease (HD) exercises considerable traction on the anorectal tissue during dissection. So the question arises as to whether TERPT impairs the integrity of the anorectal sphincter. Computerised 8-channel vector manometry allows a segmental, 360 degrees analysis of muscular defects along the anal canal. Such data after TERPT are not available yet. METHODS: Between 2002 and 2004, 7 children underwent primary TERPT for HD of the rectosigmoid. All could be recruited for follow-up examinations. Stooling pattern, rectal examination, conventional 4-channel and computerised 8-channel vector manometry were assessed; the anal sphincter pressure at rest (ASPR), rectoanal inhibitory reflex (RIR), anal canal length (ACL), high pressure zone (HPZ), maximal segmental pressure (max SP), segmental/total asymmetric index (SAI/TAI), vector volume at rest (VV) were studied. Mean pre- and postoperative values were compared (pre/post). RESULTS: After a mean of 14 months (range 3-21 months) all children had spontaneous bowel movements, with no complaints of encopresis or constipation. 4-channel manometry revealed an unchanged ASPR (48.1/49.2 mmHg). RIR was present in 1/7. Computerised 8-channel comparison revealed no changes for ACL (15.4/16 mm), HPZ (60/53.19 % of ACL), SAI (17.6/18.63 %) and TAI (35.8/35.63 %). A postoperative increase was noted for max SP squeeze (141.4/178.7 mmHg) and VV (38 161/46 680 mmHg/cm (2)). In conclusion, the TERPT for HD preserves the functional integrity of the anorectal sphincter complex and has a favourable clinical and manometric outcome.     

先天性巨结肠Soave术后大便失禁的评价和治疗

目的 对先天性巨结肠Soave术后大便失禁进行评价和治疗.方法 先天性巨结肠Soave术后大便失禁患儿24例,男14例,女10例,年龄6～13岁,肛门功能临床评价为良19例,差5例.全部患儿行肛门直肠测压,并与18例肛门功能正常的Soave术后儿童比较.所有患儿在医院接受生物反馈训练2周后自行在家中行盆底肌收缩训练.结果 肛管静息压、收缩压、直肠初感觉分别为(18.9±6.2)mmHg、(179.9±17.8)mmHg、(45.4±9.4)ml,与18例对照组儿童相比[分别为(44.5±11.1)mmHg、(177.7±15.9)mmHg、(50.0±10.1)ml],静息压明显下降,收缩压、直肠感觉无明显变化.3例不配合治疗,21例1年后除5例未能坚持外,其余16例获得良好的肛门控制,肛管静息压、肛管收缩压、直肠初感觉分别为(35.4±8.7)mmHg、(195.3±15.0)mmHg、(45.9±8.4)ml.肛管静息压和收缩压均升高.结论 内括约肌损伤可能是先天性巨结肠Soave术后大便失禁的原因之一,对此盆底肌训练可取得满意的治疗效果.

Abstract：

Objective To evaluate the efficacy of pelvic floor muscle exercise for the treatment of fecal incontinence after Soave procedure for Hirschsprung's disease. Methods Twenty four patients who had Soave procedure for Hirschsprung's disease and presented fecal incontinence after surgery were recruited in this study. They were 14 males and 10 females, aged from 6 to 13 years old. Eighteen children who had normal defecation after Soave procedure were selected as controls. All the subjects had manometry to measure resting anal canal pressure, squeeze pressure, and rectal sensation.All the patients had two weeks biofeedback therapy during their stay in hospital. After being discharged, they were taught and prescribed to do pelvic floor muscle exercise at home. Results Of the children with fecal incontinence, the resting anal canal pressure, squeeze pressure and rectal sensation were ( 18. 9 ± 6. 2 ) mmHg, ( 179. 9 ± 17. 8) mmHg, (45. 4 ± 9. 4) ml, respectively. Compared with the controls, the resting anal canal pressure was lower [(18. 9±6. 2) mmHg vs (44. 5 ± 11.1) mmHg].But no difference of squeeze pressure and rectal sensation was found between the 2 groups [(179. 9 ±17. 8)mmHg vs (177. 7 ± 15. 9) mmHg, (45.4 ± 9. 4)ml vs (50. 0 ± 10. 1)ml]. Three patients dropped out of the therapy. Five patients stopped the exercise after the first year. The other 21 who kept exercise improved their defecation function. Their resting anal canal pressure, squeeze pressure and rectal sensation were (35. 4 ± 8. 7)mmHg, (195. 3 ± 15.0)mmHg and (45. 9 ± 8. 4)ml, respectively. Conclusions The dysfunction of internal anal sphincter might be the main cause for fecal incontinence after Soave procedure. Pelvic floor muscle training is helpful to improve the defecation function of the patients.     

Anorectal manometry results in defecation disorders.

Anorectal manometry and suction biopsy were carried out on 47 children with constipation or soiling, or both. Patients were divided into two groups. Group 1 (37 patients): functional faecal retention, group 2 (10 patients): functional faecal soiling without retention. Ganglion cells or normal acetylcholinesterase staining, or both, was demonstrated in all cases. Normal inhibition of internal sphincter could be achieved by rectal distension in all except 2 children with severe constipation. Resting sphincteric pressures, pressure responses, and conscious rectal sensitivity thresholds were similar in groups 1 and 2, but were increased compared with controls. In group 1 alone, the critical volume increased parallel with conscious rectal sensitivity threshold. Since the complete relaxation of internal sphincter occurs before conscious rectal sensation arises in children with soiling without retention, this may be an important factor, at least in some of the soilers.

目的 评价改良Soave结合结肠切端缩口缝合术治疗先天性巨结肠的术后疗效.方法 回顾性分析2005年7月至2009年8月在我院行改良Soave结合缩口缝合术的32例巨结肠患儿术后恢复情况,设为观察组,选取32例行单纯改良Soave根治术的患儿为对照组.观察术中扩张段肠管断端病理切片、术后复查肛诊、肛门镜、钡灌肠及直肠肛管测压并对二组患儿排便功能进行评分.结果 观察组中26例扩张段断端神经节细胞数量正常,无明显变性,6例神经节细胞数量减少,存在变性,对照组中前者28例,后者4例.肛诊及肛门镜示术后半年以上缩口缝合结肠黏膜皱褶基本消失.钡灌肠示结肠均无明显扩张,结肠形态恢复良好.观察组和对照组术后1年排便功能评分及直肠肛管测压中的肛管高压区长度、肛管静息压、直肠感觉阈值,分别为6.6±1.3、(2.0±0.7)cm、(53.1±3.9)mmHg、30～55 ml;6.8±1.2、(1.9±0.6)cm、(52.6±4.7)mmHg、35～60 ml,均无统计学差异.术后并发症观察组有吻合口狭窄1例,二组轻度污粪各1例.结论 改良Soave结合结肠切端缩口缝合巨结肠根治术后结肠及排便功能恢复满意,与单纯改良Soave术式疗效无差异.扩张但功能良好的近端结肠切端管径大于肛门口径时,可行结肠切端缩口缝合术,该术式可成为改良Soave手术较好的辅助手段.

Abstract：

Objective To evaluate the efficacy of modified Soave procedure combined with colon plication for the treatment of Hirschsprung's disease (HD) in children.Methods Between July 2005 and August 2009,32 HD patients of the plication group underwent modified Soave procedure combined with colon plication at this center.Another 32 patients who underwent modified Soave procedure were enrolled as the controls.The pathological examinations,follow-up,barium enema,anorectal manometry,and anorectal function were retrospectively reviewed and analyzed to evaluate the surgical efficacy.Results Of the 32 patients of the plication group,26 had normal ganglion cells at both ends of the dilated intestine,and decreased ganglia number and ganglia degeneration were found on the other 6 patients.However,among the 32 control patients,decreased ganglia number and ganglia degeneration was only found on 4 patients.Rectoscopy suggested that mucosa rugae caused by colon plication could eventually disappear half a year after the surgery.On patients' barium enema radiography,no dilated intestines were observed.No difference of the defecation function scores between the plication group and control group at 1 year after operation was found (defecation function score,6.6 ± 1.3 vs 6.8 ±1.2).Moreover,there was no difference of high pressure zone length (2.0 ± 0.7 cm vs 1.9 ± 0.6 cm),anal canal resting pressure (53.1 ± 3.9 mmHg vs 52 ± 4.7 mmHg) and sensation threshold (30～55 ml vs 35～60 ml) between the 2 groups 1 year after operation.Postoperative complications included anastomotic stenosis was noted on 1 patients of the placation group,1 of the plication group and 1 control patient had mild soiling.Conclusions Modified Soave procedure combined with colon plication improves the defecation function of the HD patients.     

Anorectal myectomy in treatment of ultrashort segment Hirschsprung's disease. Report of 26 cases

A diagnosis of Hirschsprung's disease should be considered in children with constipation. An accurate neonatal history of bowel function and testing of anorectal pressure responses will aid the diagnosis. In the period 1971-75 inclusive, 140 children, aged 6 months to 14 years, were investigated by anorectal manometry. 26 showed a failed inhibition response to rectal dilatation, suggesting Hirschsprung's disease and were treated by anorectal myectomy. In 24 the disease was confirmed histologically. Two specimens were diagnostically unsuitable. 4 required repeat myectomies, and 3 anterior resection. At follow-up all had normal bowel movements without soiling.
