Abstract
BACKGROUND Despite identifying numerous risk factors for postoperative Hirschsprung-associated enterocolitis (HAEC), predicting individual risk remains challenging. This study aimed to develop a clinical prediction model for predicting the probability of postoperative HAEC within 5 years after surgery in Hirschsprung individuals. METHODS The study included all children with Hirschsprung disease who underwent definitive surgery at Chiang Mai University Hospital from 2006 to 2021. Concomitant anorectal abnormalities and incomplete data were excluded. A multivariable logistic regression analysis, adjusted for correlated data, was utilized to develop the prediction model. RESULTS Of the included 274 patients, 75 patients (27.4%) experienced postoperative HAEC within 5 years, totaling 121 episodes. Based on statistical and theoretical significance, eight parameters were utilized as predictors, which included male (OR1.23,95%CI:0.53-2.86), trisomy21(OR1.34,95%CI:0.21-8.45), weight at the time of surgery (OR0.86,95%CI:0.73-1.02), absence of exclusive breastfeeding (OR1.51,95%CI:0.65-3.51), length of the aganglionic segment (rectosigmoid (OR1.32,95%CI:0.48-3.62), long segment (OR41.39,95%CI:3.00-570.37), and total colonic aganglionosis (OR710.20,95%CI:23.55-21420.72)), preoperative stoma (OR1.72,95%CI:0.34-8.58), surgical approach (Duhamel (OR0.06,95%CI:0.01-0.81) and abdominal assisted trans anal endorectal pull-through (OR0.04,95%CI:0.002-0.65)), and early HAEC before two weeks following surgery (OR1.98,95%CI:0.67-5.82). The derived predictive model exhibited acceptable discriminative performance (AuROC:0.749,95%CI:0.679-0.816). Risk groups were categorized into low and high-risk, with positive likelihood ratios of 0.65 and 10.70, respectively. Recommendations for management and follow-up were generated based on these risk groups. An online application has been developed for calculating individual risk of postoperative HAEC and offering management suggestions with follow-up schedule: [https://w1.med.cmu.ac.th/surgery/personnel/pedsurgerycmu/#HAEC-Calculator]. CONCLUSIONS This risk predictive model accurately estimates the probability of postoperative HAEC within 5 years after surgery in Hirschsprung patients. It facilitates risk stratification and provides personalized recommendations to parents for the prevention and early detection of postoperative HAEC. LEVELS OF EVIDENCE Level II Retrospective cohort study (Prognosis study).

Abstract
PURPOSE To identify prognostic factors of postoperative Hirschsprung-associated enterocolitis (HAEC). METHOD A retrospective cohort study of Hirschsprung patients between 2006 and 2021 was conducted. Patients with anorectal malformation and non-definitive surgery were excluded. Associated factors for postoperative HAEC were reported with hazard ratio (HR) and 95% confidence interval (CI). RESULTS Forty-nine patients were excluded due to concurrent anorectal malformation and incomplete data. Of 274 patients, 75 patients (27.4%) had at least one episode of postoperative HAEC. There were 28 patients (37.3%) who had multi-episodes of HAEC. The total episodes of post-operative HAEC in this study were 121 episodes (36.8%). In multivariable survival analysis, significant factors associated with postoperative HAEC were the aganglionic level above sigmoid colon (HR = 3.47, p = 0.023, 95% CI 1.19-10.09), and total colonic aganglionosis (HR = 14.83, p = 0.004, 95% CI 2.33-94.40). The patients who experienced clinical enterocolitis before 2 weeks after surgery significantly developed more postoperative HAEC (HR = 5.32, p = 0.038, % CI 1.09-25.92). The incidence of postoperative HAEC was increase in patients with postoperative obstructive symptoms (48.0%). One patient died due to severe sepsis from postoperative HAEC, while three others required intensive care. CONCLUSIONS The long involvement of aganglionic segment and early postoperative HAEC was significantly associated with postoperative HAEC. Frequent follow-up, parental education, and early treatment are recommended in these individuals, particularly in the first year after surgery.

Abstract
Hirschsprung-associated enterocolitis (HAEC) was described in 1886 by Harald Hirschsprung and is a potentially deadly complication of Hirschsprung Disease. HAEC is classically characterized by abdominal distension, fever, and diarrhea, although there can be a variety of other associated symptoms, including colicky abdominal pain, lethargy, and the passage of blood-stained stools. HAEC occurs both pre-operatively and post-operatively, is the presenting symptom of HSCR in up to 25% of infants and varies in overall incidence from 20 to 60%. This article reviews our current understanding of HAEC pathogenesis, diagnosis, and treatment with discussion of areas of ongoing research, controversy, and future investigation.

Abstract
BACKGROUND/PURPOSE The purpose of this study was to review the management of obstructive symptoms and enterocolitis (HAEC) following pull-through for Hirschsprung's disease. METHODS A systematic review and meta-analysis (1992-2017) was performed. Included studies were: randomized controlled trials (RCT), retrospective/prospective case-control (C-C), case-series (C-S). Random-effect model was used to produce risk ratio (RR) [95% CI]. P < 0.05 was considered significant. RESULTS Twenty-nine studies were identified. Routine postoperative dilatations (5 C-S, 2 C-C; 405 patients): no effect on stricture incidence (RR 0.3 [0.02-5.7]; p = 0.4). Routine postoperative rectal irrigations (2 C-C; 172 patients): reduced HAEC incidence (RR 0.2 [0.1-0.5]; p = 0.001). Posterior myotomy/myectomy (4 C-S; 53 patients): resolved obstructive symptoms in 79% [60.6-93.5] and HAEC in 80% [64.1-92.1]. Botulinum toxin injection (9 C-S; 166 patients): short-term response in 77.3% [68.2-85.2], long-term response in 43.0% [26.9-59.9]. Topical nitric oxide (3 C-S; 13 patients): improvement in 100% of patients. Probiotic prophylaxis (3 RCT; 160 patients): no reduction in HAEC (RR 0.6 [0.2-1.7]; p = 0.3). Anti-inflammatory drugs (1 C-S, sodium cromoglycate; 8 patients): improvement of HAEC in 75% of patients. CONCLUSIONS Several strategies with variable results are available in patients with obstructive symptoms and HAEC. Routine postoperative dilatations and prophylactic probiotics have no role in reducing the incidence of postoperative obstructive symptoms and HAEC. TYPE OF STUDY Systematic review and meta-analysis.

Abstract
Both the Swenson and the Soave procedures have been adapted as transanal approaches. Our purpose is to compare the outcomes and complications between transanal Swenson and Soave procedures.This clinical analysis involved a retrospective series of 148 pediatric patients with HD from Dec, 2001, to Dec, 2015. Perioperative/operative characteristics, postoperative complications, and outcomes between the 2 groups were analyzed. Students' t-test and chi-squared analysis were performed.In total 148 patients (Soave 69, Swenson 79) were included in our study. Mean follow-up was 3.5 years. There are no significant differences in overall hospital stay and bowel function. We noted significant differences regarding mean operating time, blood loss, and overall complications. We noted significant differences in mean operating time, blood loss, and overall complications in favor of the Swenson group when compared to the Soave group (P < 0.05).According to our results, although transanal pullthrough Swenson cannot reduce overall hospital stay and improve bowel function compared with the Soave procedure, it results in less blood loss, shorter operation time, and a lower complication rate.

Abstract
BACKGROUND Hirschsprung's disease (HD) is a relatively common congenital disease that could be suspected by clinical symptoms, abdominal plain X-ray, and finally diagnosed by rectal biopsy. In 80% cases, rectosigmoid junction is involved. Recently, one-stage transanal pull-through (TAPT) procedure has been popular and may have several complications. METHODS AND PATIENTS During a 4-year period, 86 infants (28 girls, 58 boys) with mean age 8 days (3-33) and clinically suspected to HD were admitted in our center. HD was proved by rectal biopsy. All patients after full bowel preparation and rectal washout were candidates for TAPT operation. A Swenson-like procedure was performed and the anastomosis was done between the well blood supply ganglionic colon and the rectum at 1 cm above dentate line. Interrupted suture with 5-0 Vicryl was used. Nelaton tube (12 F) inserted in the pelvis via transprineal for drainage of blood or collection. From February 2008 in 30 cases, prophylactic Hegar dilatation was performed 2 weeks after operation. RESULTS Anal stricture in 12 cases (14%) was treated by anal dilation in 10 cases and 2 cases corrected by surgical management. Entrocolitis in 4 cases (5%) was treated by medical management. In two cases, retrocolic abscess had spontaneous drainage via tube drain. There was no anastomotic stricture after starting prophylactic anal bouginage. CONCLUSION TAPT has many advantages, low complications and the results are excellent. It seems the most common complication is anastomotic stricture that responds well to prophylactic bouginage. We recommend prophylactic anal bouginage with Hegar probe at 2 weeks after operation. Long-term follow-up is needed to evaluate the outcomes of our operations.

Abstract
PURPOSE Previous studies have reported decreased continence in patients undergoing transanal endorectal pull-through (TERP) for Hirschsprung's disease compared to the older transabdominal approach (TAA). To address this, we examined long-term stooling outcomes in a large, multicenter cohort of patients undergoing either TERP or TAA. METHODS Data were collected from 5 large pediatric institutions. Patient families were surveyed using a stooling score system (0-40, best to worst total score). Inclusion criteria included patients older than 3 years and those who had more than 6 months of recovery after pull-through. Those with total colonic aganglionosis were excluded. Statistical analysis included univariate and multivariate linear regression (significance, P < .05). RESULTS Two hundred eighty-one patients underwent TERP (192) or TAA (89). Interviews were completed in 149 (104 [52%] TERP vs 45 [52%] TAA). The TAA group had a significantly greater number of daily bowel movements for each respective postoperative year and experienced more early complications (3% vs 1% with >1 complication; P = .061) and late complications (19% vs 4% with >1 complication; P < .001). Although the TAA group had a higher mean enterocolitis score (3.3 +/- 0.4 vs 1.8 +/- 0.2; P < .001), this was not borne out by multivariate regression analysis (P = .276). Parental survey showed that there were no significant differences between procedures in mean total, continence, or stooling pattern scores. CONCLUSION Transanal endorectal pull-through was associated with fewer complications and fewer episodes of enterocolitis. In contrast to prior studies, TERP patients did not have a higher rate of incontinence. These results support use of TERP as an excellent surgical approach for children with Hirschsprung's disease.

Abstract
OBJECTIVE The authors describe an experience with a newly developed technique for the treatment of Hirschsprung's disease (HD)-transanal Swenson pull-through operation (TSPT). METHODS The records of 27 children (15 males and 12 females) with HD proven on the basis of rectal biopsy or barium enema who underwent primary TSPT between November 2003 and April 2008 were retrospectively reviewed. Rectosigmoidectomy begins at the level just above dentate line in neonates and approximately 1-cm above dentate line in older children. The full-thickness dissection is performed upward around the rectum. The colon is transected above transition zone and anastomosed to the anus. All patients had postoperative pathologic proof. Data are expressed as mean and SD. RESULTS Mean age at operation was 29.4 +/- 48.2 months (range, 1-155 months). The operative time averaged 153.5 +/- 85.9 min (range, 65-400 min). There was a statistically significant difference between those younger than 1 month (107.1 +/- 14.8 months) and those greater than 1 month (190.7 +/- 101.1 months). None did receive blood transfusion. Average length of hospital stay was 9.1 +/- 4.1 days (range, 4-21 days). Peri- and postoperative complications included anastomotic stricture (n = 6), enterocolitis (n = 3), and urethral injury (n = 1). Fecal continence (stooling frequency rate of 1-2 times per day) was noted in 70.8% (17/24) and 77.8% (14/18) at 1- and 2-year follow-up, respectively. There was no mortality in the series. CONCLUSIONS Primary TSPT would be an alternative, safe technique in children with HD. The technique is not difficult, and associated with acceptable short-term outcomes. A long-term follow-up will be necessary to assess the real benefit of the technique.

Abstract
PURPOSE Both the dentate line (DL) and anorectal line (ARL) are anatomic landmarks for rectal mucosal dissection during transanal pull-through for Hirschsprung disease. We compared outcome after rectal mucosal dissection commencing above the DL (DL group; n = 8) with outcome after rectal mucosal dissection commencing on the ARL (ARL group; n = 6) with normal babies (Cont group; n = 10). METHODS Rectal mucosal dissection commenced on the ARL in the ARL group and at various levels (0-10 mm) above the DL in the DL group. Outcome was assessed prospectively for 6 months using a standard structured questionnaire. RESULTS Subject demographics were not significantly different. Differences in frequency of motions between the ARL and Cont groups were not statistically significant after 3 months of age, but the DL group had significantly more motions than the other 2 groups after 4 months of age (P < .01). At 6 months of age, fecal staining was 17% in the ARL group, 63% in the DL group, and 0% in the Cont group. Anal shape was normal in the ARL and Cont groups, but 50% of the DL group had visible anal mucosa. CONCLUSION Bowel function in the ARL group is similar to normal, and because the ARL is easily identifiable without the need for subjective interpretation, we recommend using the ARL as a landmark for rectal mucosal dissection during transanal pull-through for Hirschsprung disease.

Abstract
The Soave endorectal pullthrough is a commonly performed procedure for the definitive management of children with Hirschsprung's disease (HD). Anastomotic stricture is a recognised complication of this procedure. There are multiple causes for these strictures, circular anastomosis being one of them. There are techniques described which alter the shape of the anastomosis of the pulled through bowel to decrease the incidence of strictures. These are oblique and heart-shaped anastomoses. We describe a new technique of oblique anastomosis where the pulled through bowel is anastomosed posteriorly 0.5 cm from the dentate line, and anteriorly 1.5 cm above this point. This oblique anastomosis is designed to lower the stricture rate. If a stricture does occur, an anastomosis near the anocutaneous junction on the posterior aspect also faciltates Y-V anoplasty. We present our experience using this technique. Seventeen consecutive children underwent the procedure at our institution between 2003 and 2006. Only one child developed an anastomotic stricture requiring anal dilatation.

Abstract
BACKGROUND The primary aim of this study is to detail the problems, complications, their avoidance, and management with transanal pull-through developed from experience with 65 patients. METHODS A retrospective study of 65 patients who underwent transanal pull-through between January 2002 and December 2006 was conducted. Their medical charts and operative notes were reviewed for problems encountered during surgery, postoperative period, and follow-up. RESULTS In 46 patients, a primary transanal pull-through was performed, whereas in 19 with a prior colostomy, followed staged pull-through was done. The minimum follow-up was 6 months, with an average of 22 months after surgery (range, 6-47 months). Sixteen patients (25%) experienced at least 1 complication. These included inadvertent full-thickness mobilization of the rectum in 3 (4.6%), retraction and bleeding of colonic mesenteric vessels in 2 (3.7%), difficulty in mobilizing intraperitoneal colon in 1 (1.5%), and a false-positive frozen section in 2 patients (3%). Early postoperative complications occurred in 7 patients (11%), which included sphincter spasm in 3 (4.6%), anastomotic leak in 1 (1.5%), cuff abscess in 2 (3%), and enterocolitis in 1 (1.5%). Late postoperative complications in 46 patients (70%), occurring from 1 week till 3 months of follow-up included perianal excoriation in 22 (34%), increased stool frequency in 20 (31%), anal stenosis in 3 (4.6%), and enterocolitis in 2 patients (3%). Methodology is detailed for avoidance and management of problems and complications. Individual patient analysis, complications timing, and strategy for management are discussed. CONCLUSION Patient outcomes for transanal pull-through have improved significantly as a result of combination of experience and the ability to avoid and manage associated complications. Experience, avoidance, and interdiction are key factors in complication management.

One-stage transanal pull-through (TAP) has become a standard definitive procedure for the treatment of Hirschsprung's disease (HD). Short-term results of this operation seem to be excellent, but long-term outcome is still obscure. We evaluated the morbidity and mortality of our patients with one-stage TAP, and we reviewed the literature. We performed a TAP without a colostomy in 21 patients with HD. The primary outcome measures are age, sex, complications during surgery, enterocolitis (EC) attacks after surgery, postoperative stooling problems and mortality. All patients were called over telephone, and their clinical and functional outcomes were obtained. Case series of TAP in the literature were also reviewed in terms of postoperative problems. Twenty-one patients with full thickness rectal biopsy-proven HD underwent one-stage TAP. Average follow-up was 28 months. One early postoperative EC and three more late attacks of EC were observed. All survived patients had normal bowel habits. Three patients had perianal excoriations, three patients soiling, seven cases required anal dilatations and four patients experienced a diarrhea after surgery. We have been informed that four patients died after discharge from hospital. Two of them were a sudden death (one patient had metabolic problems, the other might have had an EC attack). The cause of death of one patient with an associated Down syndrome was a severe pneumonia, and one other case died of a septic shock of unknown etiology. None of these patients had a diarrhea or abdominal distention, which could have been an evidence of an EC attack prior to their deaths. We observed similar fatal cases, when reviewed the published series in the literature. There might be a hidden mortality within the long-term period after TAP for HD. Therefore, we recommend a close follow-up for all patients with any associated health problem and those from low socioeconomic regions after one-stage pull-through.

Abstract
We report a case of persistent obstruction after laparoscopy-assisted transanal endorectal pullthrough for Hirschsprung's disease in a 4-week-old boy with biopsy-proven HD. Before pull-through, the posterior rectal cuff was split along its entire length cranially, starting from the dentate line. Initial recovery was uneventful; however, signs of obstruction developed 3 weeks postoperatively. Reoperation through a posterior sagittal approach confirmed a residual rectal cuff surrounding the neo-rectum circumferentially. The dorsal side of the residual rectal cuff was removed completely. At follow-up 5 years later, he defecates 2 to 4 times a day with occasional staining. We hypothesize that the persistent postoperative obstruction was caused by a long residual rectal cuff that spontaneously reapproximated and/or became folded during pull-through. Therefore, a shorter cuff with near-total posterior excision should be strongly considered during laparoscopy-assisted transanal endorectal pull-through for Hirschsprung's disease.

Abstract
The aim of this study was to analyze the short- to mid-term outcome of primary modified Georgeson's laparoscopy-assisted endorectal pull-through (PMGLEPT) for Hirschsprung's disease (HD). HD patients treated by PMGLEPT were evaluated prospectively by a single surgeon using a standard structured questionnaire to assess complications, incidence of enterocolitis, and evaluate continence (CE). CE involved scoring five parameters (frequency of motions, severity of staining/soiling, severity of perianal erosions, anal shape, and requirement for medications) on a 3-point scale (0, 1, and 2 for each parameter). Thus, scores for CE were: 10 = normal, 8-9 = good, 6-7 = fair, and 0-5 = poor. Our modifications include transanal rectal dissection starting below or on the dentate line, near total excision of the posterior rectal cuff, and intraoperative acetylcholinesterase staining to accurately identify normal colon. Patients with total colon aganglionosis or trisomy-21 were excluded, leaving 33 cases of PMGLEPT performed between 1997 and 2004. Mean operative age was 11.0 months. Follow-up ranged from 8 months to 7 years (mean 4.0 years). There were no intraoperative complications. Post-PMGLEP, bowel obstruction occurred in 1 subject who required middle colic division for pull-through (PT), and enterocolitis occurred in 3 (9.1%) of 33 patients. In 20 subjects aged over 3 years with a follow-up period of more than 12 months, final CE was normal in 5, good in 10, fair in 4, and poor in 1, despite staining/soiling being present in 12 (60%) of 20 subjects. None of the 33 had constipation. Our results suggest that PMGLEPT is safe with acceptable outcome in the short- to mid-term. However, careful long-term follow-up is mandatory as there appears to be a relatively high incidence of staining/soiling on short- to mid-term follow-up.

Abstract
BACKGROUND There has been a recent trend in the use of laparoscopic-assisted one-stage pull-through in the management of Hirschsprung's disease (HD). We describe our initial experience using laparoscopy with a transanal coloanal anastomosis as described by Rintala and Lindhal for HD. METHODS Six children with biopsy-confirmed HD underwent laparoscopic-assisted pull-through using Rintala's transanal endorectal coloanal anastomosis. The procedure was done through one 5-mm camera port and two 5-mm working ports. The transition zone was identified by seromuscular biopsies obtained laparoscopically. The sigmoid colon and proximal rectum were mobilized laparoscopically. A transanal endorectal mucosal dissection and a coloanal anastomosis were done, using an absorbable monofilament 5/0 polyglyconate suture. RESULTS Six children aged 4 weeks to 36 months underwent this procedure laparoscopically. Two cases had to be converted to an open procedure as a result of dense pelvic adhesions. The entire mobilization of the bowel as well as biopsy confirmation of the transition zone was done laparoscopically in all 6 cases. The median operative time was 135 minutes (range, 120-240 minutes). All 6 children tolerated full enteral feeds after 48 hours and the median hospital stay was 7 days (range, 6-10 days). There were no early postoperative complications. Two cases developed mild enterocolitis that resolved with conservative management. The overall functional outcome was good in all cases with no soiling, stool incontinence, or constipation at a median follow-up period of 12 months (range, 4-27 months). CONCLUSION Laparoscopic-assisted pull-through, apart from being cosmetically superior, permits obtaining biopsies as well as an adequate mobilization of the bowel. The transanal endorectal coloanal anastomosis technique is simple and easy to perform, with a minimal dissection which causes less damage to the internal sphincter and pelvic nerves.

Abstract
Hirschsprung (HSCR) disease is a relatively common neonatal developmental disorder of the enteric nervous system and is characterized by the absence of ganglion cells in the myenteric and submucosal plexuses of the distal intestine. This results in absent peristalsis in the affected bowel, and the development of a functional intestinal obstruction. The pathogenesis and genetic basis of the disease is yet unclear. The surgical treatment of HSCR has evolved significantly since 1949 when Swenson first proposed a trans-abdominal pull-through procedure. The transanal pull-through consists of a rectal mucosectomy, resection of the aganglionic bowel and a colo-anal anastomosis. Recent literature and clinically controversies of this minimally invasive one-stage procedure are reviewed. Although follow up is still relatively short the preliminary results appear very favorable and cost effective.

Abstract
Many children with Hirschsprung's disease (HD) have a good outcome following surgical treatment, but long-term follow-up studies have identified a number of concerns. Analysis of long-term function in children after surgical management is difficult. The most commonly encountered problems include constipation, incontinence, enterocolitis and the overall impact of the disease on lifestyle (quality of life). Other complications are less frequent. Each of these problems will be discussed.

Abstract
BACKGROUND/PURPOSE Transanal endorectal pull-through (TEPT) is the latest development in treatment of Hirschsprung's disease (HD). This prospective study was designed to evaluate the safety and efficacy of 1 stage TEPT technique in the management of patients with HD. METHODS One hundred forty-nine children (116 boys and 33 girls) aged 8 days to 14 years underwent 1 stage TEPT procedure over an 18-month period at 5 Egyptian academic pediatric surgical centers and affiliated hospitals. Median follow-up was 12 months (range, 3 to 21 months). These patients were evaluated with regard to age, sex, length of the aganglionic segment, intraoperative details, and postoperative functional results or complications. An electromyogram (EMG), endorectal ultrasound scan, and lower gastrointestinal (GI) motility studies were reserved for patients with postoperative problems with bowel control. RESULTS Mean operating time was 120.2 +/- 27.8 minutes (range, 60 to 210 minutes). The average length of resected bowel was 26.8 +/- 12.4 cm (range, 15 to 45 cm). Thirteen patients required laparotomy because of extension of aganglionic segment beyond the sigmoid colon in 9, tear in the mesenteric vessels in 2, and difficulties in getting to the submucosal plane in 2. Three deaths (2%) occurred 3 days, 4 days, and 4 weeks postoperatively, respectively. Postoperative complications included transient perianal excoriation in 48 patients (30 were <3 months of age), enterocolitis (n = 26), anastomotic stricture (n = 7), recurrent constipation (n = 6), hypoganglionosis at distal end of pulled through segment (n = 2), cuff abscess (n = 3), anastomotic leak (n = 1), adhesive bowel obstruction (n = 1), and rectal prolapse (n = 1). Complete anorectal continence was noted in 35 of 42 (83.3%) children older than 3 years, whereas soiling and frequent accidents still occur in 7, who showed a steady improvement in their continence status. CONCLUSIONS One-stage TEPT technique is both feasible and safe technique in properly selected children with rectosigmoid HD in all ages. The technique is easily learned and is associated with excellent clinical results.

Abstract
BACKGROUND/PURPOSE Transanal pull-through has been advocated recently for classic Hirschsprung's disease. The procedure leaves no scars, is associated with less postoperative pain and discomfort, and shortens hospital stay. Long-term functional outcome of patients having transanal pull-through is unclear, but short-term function is reported to be very similar to that after open or laparoscopic procedures. One-stage neonatal repair of Hirschsprung's disease has been suggested to be associated with less cost and demand of resources without jeopardizing functional outcome. The aim of this study was to ascertain the feasibility and safety of transanal pull-through in the neonatal period. METHODS Case notes of 40 consecutive patients who had undergone transanal endorectal pull-through for Hirschsprung's disease between January 2000 and February 2003 were reviewed. The patients were divided in to 3 groups: patients with neonatal primary pull-through (group I, 15 patients), patients operated on beyond the neonatal period (group II, 11 patients), and patients with a previous colostomy (group III, 14 patients). All colostomies except one were taken down and pulled through concomitantly with the transanal procedure. The case notes were evaluated for hospital stay, time to full oral feedings, operative and postoperative complications, need for postoperative dilatations, and occurrence of postoperative enterocolitis. RESULTS There was no difference in median hospital stay (group I, 5 days; group II, 4; group III, 5) and median time to full oral feedings (group I, 4 days; group II, 2; group III, 3) between groups. Two patients (group III) had immediate postoperative prolapse of the pulled-through colon that was reduced without further sequels; 1 (group III) had infection of the stoma closure wound. Perianal skin rash that usually resolved within 6 weeks occurred more often in neonatal patients (group I, 10 of 15; group II: 4 of 11; group III: 8 of 14). Anastomotic dilatation regimen was required more often in neonatal cases (group I, 6 of 15; group II, 1 of 11; group III, 2 of 14). Enterocolitis requiring hospital care occurred in 2 patients (group I), 5 further patients (group II, 1; group III, 4) were treated as outpatients for symptoms suggesting mild enterocolitis or bacterial overgrowth. The median follow-up was 6 months. CONCLUSIONS Transanal endorectal pull-through in neonatal patients is as feasible and safe as in older children or in those with a levelling colostomy. However, temporary postoperative skin rash occurs more frequently in neonatal patients, and postoperative dilatations are required more often than in older children.

Abstract
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.

Abstract
BACKGROUND/PURPOSE Fifteen consecutive children aged 20 days to 12 years with biopsy-proven Hirschsprung's Disease (HD) underwent a transanal pull-through procedure over a 17-month period. These patients have been divided into 2 groups. The first was a series of 9 patients, which helped us gain familiarity and confidence with technical and postoperative gestational problems, and the second series was of 6 patients, which fully corroborates and adds further evidence on the minimally invasive nature of the technique. Mucosectomy of aganglionic bowel, access to the peritoneal cavity, division of rectosigmoid mesenteric vessels, pull-through of normoganglionic colon, colectomy, and coloanal anastomosis all were performed transanally. Patients underwent a program of progressive anal dilatations and were assessed for postoperative clinical course, continence, constipation, diarrhea, postoperative enterocolitis, perianal excoriations, and anal stricture. RESULTS Mucosectomy was done under direct vision. Operating time ranged from 150 to 350 minutes. The average length of bowel resected was 13.5 cm with a range of 8 cm to 25 cm. There were neither intraoperative nor significant postoperative complications. All but 2 patients accepted full oral feedings on postoperative day 2. Mean hospital stay in the first series of 9 patients was 7 days, range, 5 to 12 days; that of the second series of 6 patients was 5 days, range, 4 to 8 days. All children currently experience 1 to 6 bowel movements per day at a follow-up period of 1 to 17 months. CONCLUSIONS A one-stage pull-through procedure for HD can be performed successfully with a completely transanal approach. This technique is associated with excellent early clinical results. Many more cases and a longer follow-up period will be required to compare long-term results with other one-stage procedures for definitive treatment of HD.

Abstract
BACKGROUND/PURPOSE The aim of this study was to evaluate the indications, results, and complications of transanal endorectal pull-through (TEPT) in the management of recto-sigmoid Hirschsprung's disease (HD). METHODS Between November 1998 and March 2002, 68 TEPT procedures were performed in infants and children. The patients' ages ranged from 6 days to 13 years. The primary diagnosis in all 68 patients was Hirschsprung's disease confined to the recto-sigmoid region. All children had their operations done without construction of preoperative colostomy except for one. Follow-up period ranged from 3 to 39 months (mean, 21 months). RESULTS The mean operating time was 90 minutes, and average length of bowel resected was 25 cm. Sixty-two patients had satisfactory results without complications. Blood transfusion was needed in only 11 patients. Recovery was very fast, and patients often were hungry within 24 hours. Feeding was resumed within 48 hours. One patient required laparotomy during the procedure owing to injury to the urethra. Two patients required colostomy 3 and 5 days after surgery respectively, because of delayed leakage. Three patients suffered from attacks of enterocolitis 6 to 9 months postoperatively. There was increased frequency of defecation (5 to 15 times daily) for 4 to 6 weeks after surgery in all the patients. There was no constipation, no incontinence, no cuff abscess, and no mortality in any of the patients. Average frequency of defecation was 1 to 3 times daily after 3 months. The cost of the TEPT technique was almost half that of the open surgery. CONCLUSIONS TEPT takes less time, has less bleeding, shorter hospital stay, less morbidity, and earlier recovery than similar open pull-through procedures. The hazards and morbidities associated with laparotomy and colostomy may be avoided with a one-stage technique in Hirschsprung's disease confined to the recto-sigmoid region. Careful long-term follow-up is required to assess continence and sexual function.

Abstract
PURPOSE The authors describe a modified technique of primary transanal rectosigmoidectomy for Hirschsprung's disease (HD), using a Swenson like procedure to perform the anastomosis between the colon and the rectum, and the preliminary results from this in children. METHODS Twenty children, of whom, 90% were boys and 10% girls, 50% white and 50% nonwhite, aged 15 days to 10 years and with HD proven via biopsy, underwent a transanal pull-through procedure over a 29-month period. Postoperative follow-up ranged from 29 to 5 months. The proximal cut edge of the mucosal and submucosal cuff was tagged with multiple polypropylene 4-0 sutures, which were used for traction of the intestinal layers outside. The rectal mucosa was incised circumferentially using cautery, to perform rectal dissection approximately 1.5 cm from the dentate line, except in newborn case, in which the proximal cut edge was 0.5 cm from the dentate line. The dissection extended in an upward direction around the entire rectal circumference as far as the opening of the peritoneal reflection. The full thickness of rectum and sigmoid were mobilized outside through the anus, with division and coagulation of the rectal and sigmoid vessels using cautery or ligatures with cotton 4-0. The dissected colon then was divided above the transition zone, which was confirmed via full-thickness biopsy sections and with frozen section confirmation of ganglion cell presence. The authors performed a modified Swenson anastomosis technique, using a seromuscular polyglactin 4-0 separate-stitch suture. No drains were used. RESULTS Normal bowel movements were displayed by all patients at the follow-up. All patients underwent a defecogram and anorectal computerized manometry at 3 months after surgery that showed an absence of stenosis and good anorectal sphincter muscle complex function. The incidence of complications in our series was 10%. CONCLUSIONS During the follow-up period of 29 months, all patients had normal bowel movements and normal anorectal manometric pressure profiles.

Abstract
Hirschsprung's disease (HSCR) is the most common congenital malformation of the enteric nervous system and requires early diagnosis and surgical repair for the best comprehensive outcome. The early diagnosis of this disorder permits the use of primary endorectal pull-through (PERPT), which is now the definitive surgical therapy for HSCR. PERPT has become the preferred method of treatment for HSCR, and large numbers of successfully treated patients have been described in the recent medical literature. The rate of postoperative complications is generally similar to that following a two-stage surgical repair, but PERPT patients may be at a slightly higher risk for Hirschsprung's-associated enterocolitis. Despite recent surgical advances in the treatment of HSCR, a two-stage surgical repair involving a temporary diverting colostomy may still be necessary in up to one third of patients. Candidates for a staged repair include those HSCR patients with long-segment or total colonic disease or when there has been a delay in diagnosis that results in a markedly dilated proximal colon or patient clinical instability. Internal anal sphincter hypertonicity, occurring either as isolated primary anal achalasia or as a postoperative complication, can be successfully managed by either botulinum toxin injections or anal myectomy. The measurement of colonic motility in surgically repaired patients with a long-standing postoperative abnormality of bowel function can identify several distinct motility disorders that are amenable to separate and individualized therapies. The single most important element in the management of HSCR remains the clinical judgement of the surgeon of record, who utilizes all discernible clinical data to elect the manner of surgical repair in a given patient.

Abstract
BACKGROUND Most children with Hirschsprung's disease (HD) can be treated with a transanal endorectal pull-through (TEP) procedure. The authors have developed a simple technique of submucosal pressure-air insufflation (SI) to facilitate the submucosal dissection, which is one of the crucial parts of the operation. METHODS Six patients with HD were treated by using TEP in one year. After adequate positioning and exposure, anal mucosa was incised 1 cm above the dentate line, and 4-quadrant SI with a simple system of scalp-vein needle connected to a 20-mL syringe was used in all of the patients. Submucosal proctectomy, aganglionic and dilated segment colectomy, and coloanal anastomosis were completed transanally, but, in 2 of the patients, laparoscopic assistance to release the colon was required. RESULTS There were no intraoperative and postoperative complications related to SI. Submucosal dissections were completed smoothly in all of the patients with negligible amount of bleeding. The only complication during the submucosal dissection was mucosal perforation at the site of previous rectal biopsy in 2 patients. Average operating time was 2.7 hours (range, 90-180 min), and mean length of resected bowel was 22.5 cm (range, 12 to 42 cm). Follow-up is 8 to 14 months. Frequent bowel movements (>8 times per day) and perianal dermatitis were observed in 2 patients but returned to acceptable limits in 3 months. One patient had to undergo reoperation for adhesive intestinal obstruction. CONCLUSIONS SI is simple, and offers a safe and faster dissection with minimum amount of bleeding during the endorectal mucosectomy in TEP procedure.
