Background
We sought to identify causes of preventable complications related to operations for Hirschsprung disease.Methods
We reviewed the cases of 51 patients with Hirschsprung disease who underwent a primary procedure elsewhere, had a complication, and were referred for reoperation.Results
Thirty-five patients had 1 failed operation, 10 had 2, and 6 had 3. Initial operations were Soave (20), Duhamel (15), Swenson (5), transanal endorectal (4), myectomy (3), unknown (3), and laparoscopic Swenson (1). Thirty-one patients presented with a stoma. Patients without a stoma (20) had fecal impaction (8), recurrent enterocolitis (6), and fecal incontinence (6). None had both enterocolitis and incontinence. Reoperation was performed posterior sagittally (40) or transanally (5). Indications included stricture (21), megarectal Duhamel pouches (12), fistulae (11 [8 rectocutaneous, 2 rectourethral, and 1 rectovaginal]), pouchitis (2), and retained aganglionic bowel (8). After reoperation, 14 were continent, 11 had a stoma (8 permanent), 6 had voluntary bowel movements but soiled occasionally, 6 received rectal irrigations to avoid enterocolitis, 6 were incontinent but clean with bowel management, and 2 were lost to follow-up.Conclusion
Stricture, megarectal pouch, fistula, and retained aganglionic bowel are preventable complications. Enterocolitis is partially preventable but can occur after a technically correct procedure. Fecal incontinence is a preventable complication likely because of anal canal damage. 相似文献2.

Background
Reoperations in Hirschsprung disease may be required for residual aganglionosis or transition-zone bowel found at the distal pull-through. We aimed to review the management of patients who had this complication and offer suggestions on how to avoid it.Methods
Ninety-three patients with Hirschsprung disease were referred to our institution with recurrent problems after a pull-through done elsewhere. All required reoperations with a variety of indications, and of these, 25 had residual aganglionosis/transition-zone histology. This was the only indication for redo in 16 children.Results
Children (range, 2-17 years) presented 6 to 66 months after the initial pull-through. The predominant symptoms were enterocolitis (n = 9 [56%]), constipation (n = 7 [44%]), failure to thrive (n = 5 [31%]), and impaction (n = 4 [25%]). The rectal biopsy performed as part of their post pull-through work up showed hypertrophic nerves (n = 16), absent ganglion cells (n = 6), and normal ganglion cells (n = 10). The original frozen-section biopsy, determining the level of the pull-through, only sampled the seromuscular layer in 3 children, leading to misdiagnosis. Reoperations involved a transanal resection (n = 15) and a posterior sagittal approach (n = 1). In all cases, obstructive symptoms were resolved, and no patient has had recurrent enterocolitis.Conclusion
Patients' post pull-through with recurrent obstructive symptoms may have residual aganglionosis or transition-zone bowel. Reoperation can result in the resolution of these symptoms. A full-thickness biopsy at the time of the initial pull-through to include the mucosa and submucosa may increase the possibility of identifying hypertrophic nerves. 相似文献3.

Background/Purpose
Recently, the transanal 1-stage pull-through operation has been widely used in Hirschsprung disease (HD), and it is obviously superior to traditional approach in early term for its noninversion. However, the procedure is relatively so new that it makes assessment of the functional outcome and stooling patterns difficult. The aim of this study was to evaluate the clinical outcomes of the transanal 1-stage endorectal pull-through operation in the management of rectosigmoid HD.Methods
Fifty-eight children (39 boys and 19 girls) aged 12 months to 13 years (mean, 2 years) who underwent transanal 1-stage endorectal pull-through operation for HD were followed up from 6 to 24 months. Clinical outcome was assessed by interviews and questionnaires. All patients had an aganglionic segment confined to the rectosigmoid area which was confirmed by the preoperative barium enema and postoperative pathological examination.Results
Forty-six patients had satisfactory results without complications. In all the children, the mean stool times were 1 to 2 per day; only 4 had mean stool times of 8 to 10 per day. Postoperative soiling was present in 9, constipation in 5, and HD-associated enterocolitis in 3. There were no incontinence, cuff infection, anastomotic leak, and mortality in any of the patients. In the 12 symptomatic patients, there were 4 children with length of aganglionic segment less than 30 cm, and 8 had 30 cm or more. In the 46 asymptomatic patients, 42 had length of aganglionic segment less than 30 cm, and 4 had 30 cm or more. There was a significant difference between the group with less than 30 cm and the group with 30 cm or more of aganglionic segment. For statistical analysis, the Fisher exact test showed P < .05.Conclusions
The transanal 1-stage endorectal pull-through is a feasible and safe procedure in children with rectosigmoid HD. The clinical outcome is satisfactory. A gradual recovery could be noted in the stooling patterns along with the time after surgery. The younger the patient operated on and the shorter the aganglionic segment, the lower do the stooling disorders occur and the faster does the stooling function recover. 相似文献5.
Introduction and importanceHirschsprung’s disease is a congenital anomaly that results from an incomplete craniocaudal migration and maturation of intestinal ganglion progenitor cells leading to distal intestinal aganglionosis. Skip segment Hirschsprung’s disease is an extremely rare phenomenon. We report a case involving only the small bowel with confirmed colonic ganglionosis.Case presentationA case report of a 14-month-old with a skipped segment involving the distal 50 cm of the small bowel associated with colonic ganglionosis is presented. A current review of the literature is discussed.Clinical discussionOur patient had persistent obstructive symptoms despite undergoing a technically good, ganglionic pull-through operation at an outside institution. A laparoscopic-assisted pull-through might have documented a small bowel wall diameter discrepancy.ConclusionAlthough rare, skip segment Hirschsprung’s disease is a real phenomenon that paediatric surgeons should be aware of and could involve small and large bowels. 相似文献

Purpose
This study was conducted to determine the effect of age at diagnosis and length of ganglionated bowel resected on postoperative Hirschsprung-associated enterocolitis (HAEC).Methods
Children who underwent endorectal pull-through (ERPT) between January 1993 and December 2004 were retrospectively reviewed. t Test, analysis of variance, Kaplan-Meier, and Cox's proportional hazards analyses were performed.Results
Fifty-two children with Hirschsprung disease (median age, 25 days; range, 2 days-16 years) were included. Nineteen (37%) had admissions for HAEC. Proportional hazards regression showed that HAEC admissions decreased by 30% with each doubling of age at diagnosis (P = .03) and increased 9-fold when postoperative stricture was present (P < .01), after controlling for type of ERPT, trisomy 21, transition zone level, and preoperative enterocolitis. Thirty-six children, with age at initial operation less than 6 months, were grouped based on length of ganglionated bowel excised (A [5 cm] and B [>5 cm]). No significant difference in the number of HAEC admissions during initial 2 years post-ERPT was seen between groups A (n = 18) and B (n = 18). The study had a power of 0.8 to detect a difference of 1 admission over 2 years.Conclusions
Children diagnosed with Hirschsprung disease at younger ages are at a greater risk for postoperative enterocolitis. Excising a longer margin of ganglionated bowel (>5 cm) does not seem to be beneficial in decreasing HAEC admissions. 相似文献7.
IntroductionSegmental aganglionosis (the absence of ganglions) is a rare presentation of Hirschsprung’s disease, whereby only limited segment/segments of aganglionic bowel is interposed between segments of innervated bowel, or “skip’’ area of normal innervations is present within an area of aganglionosis.Presentation of caseWe reported a case of a 3 day old male newborn who presented with failure to pass meconium along with progressive abdominal distension. There were skip lesions present in between. Mikulicz double barrel enterostomy was carried out, which was followed by an uneventful postoperative period. Four months later, the patient was admitted for levelling biopsies which revealed the absence of ganglions in the terminal ileum as well as in the rectosigmoid junction. But the ganglions were present in between and proximal to the terminal ileum where the previously dilated small bowel segment was resected. This presentation was contradicted the most accepted migration theory of Hirschsprung’s disease.DiscussionAs seen in our case, and in21 other cases published between 1954–2016, we highly recommend that leveling/mapping biopsies should definitely include the cecal pole and the small bowel segments proximal to the ileocecal valve as well as the multilevel colonic biopsies down till the rectum.ConclusionReporting of these cases brings out interesting questions with respect to the pathogenesis and serves to highlight the existence of several variants within the spectrum of Hirschsprung’s disease. 相似文献

Purpose
Following a Soave pull-through for Hirschsprung disease (HD), some children struggle with obstructive symptoms. We hypothesized that these symptoms could result from a functional obstruction of the pull through caused by the Soave cuff, and that cuff resection might improve bowel emptying.Methods
We reviewed patients referred to our center from 2008 to 2012 with obstructive problems following a Soave pull-through for HD (CCHMC IRB # 2011–2019). Only patients with an obstructing Soave cuff were analyzed. Patients with other reasons for obstruction (anastomotic stricture, transition zone, aganglionic segment) were excluded.Results
Thirty-six patients underwent reoperation at our center for obstructive symptoms after an initial Soave pull-through. Seventeen of these patients had a Soave cuff only as the potential source of obstruction. Pre-operative symptoms included enterocolitis (10), constipation (6), and failure to thrive (1). Nine patients (53%) required irrigations to manage distension or enterocolitis pre-operatively. 14/17 patients (82%) had a palpable cuff on rectal exam. Eight patients (47%) had radiographic evidence of a cuff demonstrated by distal narrowing (4) or a prominent presacral space (4). Four children (23%) underwent excision of the cuff only. Thirteen (76%) had removal of the cuff and proximally dilated colon [(average length 7.2 cm) (12 performed transanally, and five needed laparotomy as well.)] Post-operatively, episodes of enterocolitis were reduced to zero, and need for irrigation to treat distension was reduced by 50%. Nine patients have voluntary bowel movements, and five are clean on enemas. 3/6 patients with pre-operative constipation or impaction now empty without enemas. (Follow up 1–17 months, mean 7 months.)Conclusions
Recurrent enterocolitis, constipation, or failure to thrive can indicate a functional obstruction due to a Soave cuff when no other pathologic cause exists. Physical exam or contrast enema can identify a problematic cuff. Reoperation with cuff resection can dramatically improve bowel emptying. 相似文献10.
Background/Purpose
The study aimed to develop a mouse model of post-pullthrough Hirschsprung's disease that will allow investigation of mechanisms that cause postoperative complications.Methods
We developed a novel microsurgical pullthrough operation on Balb/C mice and evaluated its effect on growth rate and stooling pattern. Histologic assessment of the pullthrough colon was performed. The pullthrough operation was then performed on Ednrb−/− mice that have aganglionic megacolon and Ednrb+/+ littermate controls, and the outcomes compared.Results
The Balb/C pullthrough group had 97% survival at 1 week and 70% survival at 2 weeks. Body weight of the pullthrough animals declined 15% in the first week after surgery and subsequently normalized. The stooling pattern showed consistently softer stools in the pullthrough group, but no difference in frequency compared to controls. Histopathologic analyses 4 weeks postoperatively showed well-healed coloanal anastomoses. Two-week survival after pullthrough surgery in Ednrb−/− and Ednrb+/+ mice was 50.0%, and 69.2%, respectively (P = NS). Increased mortality in the Ednrb−/− mice was related to the technical challenge of performing microsurgery on smaller-sized mice with poor baseline health status.Conclusions
Our microsurgical pullthrough operation in mice is feasible and allows systematic investigations into potential mechanisms mediating post-pullthrough complications and poor long-term results in mouse models of Hirschsprung's disease. 相似文献11.

Surgical pathology for Hirschsprung disease (HSCR) occasionally is difficult, especially for those who encounter the disorder infrequently. This article reviews pathologic features of HSCR, considers various specimens the pathologist is required to evaluate, and discusses useful ancillary tests. Potential diagnostic pitfalls are highlighted, and helpful hints are provided to successfully navigate challenging situations. Finally, the article looks forward to new ancillary tests on the horizon and future topics for HSCR research. 相似文献

Background The purpose of this study was to analyse the outcome of redo-endorectal pull through in Hirschsprung's disease following different
original pull through procedures. In the past, redo-endorectal pull through was mainly performed following endorectal pull
through, but not following the Duhamel procedure. We present the outcome of eight patients after redo-endorectal pull through,
including five who underwent Duhamel pull through as original procedure.
Materials and methods Between 2002 and 2004, eight patients underwent redo-endorectal pull through following the Duhamel procedure (five), Rehbein
procedure (one) and endorectal pull through (two). A retrospective study was performed to evaluate the clinical course after
redo-endorectal pull through, reviewing inpatients' and outpatients' charts and performing standardised interviews.
Results Four of eight patients had normal stool pattern after redo-endorectal pull through. In two patients mild and in another two
patients severe chronic constipation occurred after redo-surgery. Constipation-associated incontinence was noted in four patients,
which is terminated after initiation of laxative treatment in three. Enterocolitis occurred in one patient and recurrent ileitis
in another child with total colonic aganglionosis. No impairment of bladder function was observed after redo-endorectal pull
through.
Conclusion Redo-endorectal pull through proved to be a safe technique and feasible even after prior Duhamel pull through, resulting in
good clinical outcome.

Hirschsprung’s disease (HD) is a congenital disorder, characterized by aganglionosis in the distal part of the gastrointestinal tract. Despite complete surgical resection of the aganglionic segment, both constipation and fecal incontinence persist in a considerable number of patients with limited treatment options. There is growing evidence for structural abnormalities in the ganglionic bowel proximal to the aganglionosis in both humans and animals with HD, which may play a role in persistent bowel dysfunction. These abnormalities include: (1) Histopathological abnormalities of enteric neural cells; (2) Imbalanced expression of neurotransmitters and neuroproteins; (3) Abnormal expression of enteric pacemaker cells; (4) Abnormalities of smooth muscle cells; and (5) Abnormalities within the extracellular matrix. Hence, a better understanding of these previously unrecognized neuropathological abnormalities may improve follow-up and treatment in patients with HD suffering from persistent bowel dysfunction following surgical correction. In the long term, further combination of clinical and neuropathological data will hopefully enable a translational step towards more individual treatment for HD. 相似文献

BACKGROUND: The surgical management of Hirschsprung's disease (HD) has evolved from the original 3-stage approach to the recent introduction of minimal-access single-stage techniques. We reviewed the early results of the transanal Soave pullthrough from 6 of the original centers to use it. METHODS: The clinical course of all children with HD undergoing a 1-stage transanal Soave pullthrough between 1995 and 2002 were reviewed. Children with a preliminary stoma or total colonic disease were excluded. RESULTS: There were 141 patients. Mean time between diagnosis and surgery was 32 days, and mean age at surgery was 146 days. Sixty-six (47%) underwent surgery in the first month of life. Forty-seven (33%) had the pathologic transition zone documented laparoscopically or through a small umbilical incision before beginning the anal dissection. Mean blood loss was 16 mL, and no patients required transfusion. Mean time to full feeding was 36 hours, mean postoperative hospital stay was 3.4 days, and 87 patients (62%) required only acetaminophen for pain. Early postoperative complications included perianal excoriation (11%), enterocolitis (6%), and stricture (4%). One patient died of congenital cardiac disease. Mean follow-up was 20 months; 81% had normal bowel function for age, 18% had minor problems, and 1% had major problems. Two patients required a second operation (twisted pullthrough, and residual aganglionosis). One patient developed postoperative adhesive bowel obstruction. CONCLUSION: To date, this report represents the largest series of patients undergoing the 1-stage transanal Soave pullthrough. This approach is safe, permits early feeding, causes minimal pain, facilitates early discharge, and presents a low rate of complications. 相似文献

Purpose
To examine predictors of a false-positive (FP) result on contrast enema (CE) for the diagnosis of Hirschsprung disease (HD).Methods
Retrospective analysis, over a 5-year period (1999-2004), of infants (<6 months of age) with suspected HD undergoing rectal biopsy following abnormalities identified on CE (transition zone [TZ], abnormal rectosigmoid ratio, microcolon, retained contrast, or mucosal irregularity).Results
One hundred twenty-nine patients underwent rectal biopsy following an abnormal CE. The FP rate was 48.5% (66 with HD). Age below 30 days (OR, 3.4; 95% CI, 1.1-10.3), female sex (OR, 3.4; 95% CI, 1.6-7.3), and absence of TZ (OR, 6.3; 95% CI, 2.6-15.3) were independently associated with an increased risk for FP on multiple variable logistic regression. A history of bilious emesis decreased the probability of FP (OR, 0.2; 95% CI, 0.06-0.5).Conclusions
Transition zone, sex, age, and bilious emesis are important predictors of FP in those with suspected HD and CE abnormalities. With 100% incidence of FP, infants younger than 30 days with neither bilious emesis nor a TZ and female infants younger than 30 days with these features may represent a subpopulation in whom rectal biopsy can be avoided. 相似文献16.

Purpose
The reported incidence of Hirschsprung's-associated enterocolitis (HAEC) is extremely variable. A standardized definition would permit comparison of different studies and provide an interpretable outcome measure for future prospective studies in patients with Hirschsprung's disease.Methods
The Delphi method is a technique for achieving consensus among a panel of experts. A list of 38 potential criteria from the history, physical examination, radiologic studies, and pathologic specimens was made available to pediatric surgeons and gastroenterologists who have contributed to the literature on Hirschsprung's disease. Each expert ranked the diagnostic importance of each item using a Likert scale. In subsequent surveys, the same process was used, but the means and SDs from previous rounds were included as a way of influencing the experts toward consensus. Cronbach's α was used after each round to measure variability among the experts. Once consensus was reached, an overall “HAEC score” was developed by assigning a value of 1 or 2 to each item that was considered important by the expert panel. The score was then validated by circulating 10 clinical cases to the panel and asking if each represented HAEC or not.Results
Twenty-seven experts completed the survey. Cronbach's α increased from 0.93 after the first round to 0.97 after the second. Criteria receiving the highest scores were diarrhea, explosive stools, abdominal distension, and radiologic evidence of bowel obstruction or mucosal edema. Eighteen items were included in the score. During the validation process, the score agreed with the experts in 9 of the 10 case scenarios.Conclusion
The most important clinical diagnostic criteria for HAEC were identified from a larger pool of potential diagnostic items through a consensus approach using the Delphi method. A score was developed and validated and can now be used as a standardized and reproducible outcome measure for future studies in children with Hirschsprung's disease. 相似文献19.

Purpose
Ideally, fecal incontinence after operative management for Hirschsprung disease should not occur. If it does, it presents a formidable challenge. The purpose of this study was to describe the causes of fecal incontinence and present our algorithm for its treatment.Methods
We reviewed 68 patients with Hirschsprung disease and fecal incontinence referred to us after surgery at other institutions. Patients were evaluated by contrast enema and by an examination under anesthesia to look specifically for the integrity of the anal canal. They were designated as having a dilated colon and constipation or a nondilated colon and a tendency to diarrhea based on their stooling pattern and the appearance of the contrast enema. Medical management was started that included laxatives for those patients with a dilated colon and constipation. For those with a nondilated colon and tendency to diarrhea, the management included loperamide, pectin, and a special dietary regimen (constipating diet, 3 meals per day, and no snacks). Those patients who responded to medical management were retrospectively considered to have been pseudoincontinent. Those who did not respond were considered truly incontinent. The truly incontinent group was treated with enemas alone for those with a dilated colon, or enemas, loperamide, pectin, and a constipating diet for those with a nondilated colon and tendency to diarrhea.Results
Fifty-six patients had true incontinence and 12 had pseudoincontinence. Of the true incontinent group, 27 had a dilated colon and 29 had a nondilated colon. Five of these patients had a damaged or absent anal canal (anastomosis at the anal skin) and all of them had true incontinence. In the dilated colon group with true incontinence, 23 (85%) patients were clean after treatment. In the nondilated colon group with true incontinence, 23 (79%) were successfully treated. All patients in the pseudoincontinent groups had no soiling after treatment. Of 55 in the truly incontinent group, 39 (70%) had had an endorectal (Soave type) pull-through.Conclusion
Fecal incontinence after operative management of Hirschsprung disease represents a serious problem. Poor surgical technique may be a contributing factor in some of the cases. Successful management depends on the appropriate evaluation, which determines whether the incontinence is true or pseudo, and the type of colon the patient has. Each category can be well treated, leading most of the time to a clean child. 相似文献20.
