Clinical and functional outcome of total transanal endorectal pull-through procedure for the management of Hirschsprung’s disease

ObjectiveThe aim of the study is to evaluate the complications and long-term bowel function in Hirschsprung’s disease (HD) patients following total transanal endorectal pull-through (TERPT) surgery operated in a tertiary hospital in Oman.MethodsA retrospective data retrieval was done for patients diagnosed with Hirschsprung’s disease and underwent total transanal endorectal pull-through procedure during the period from December 2008 to June 2019 with concomitant prospective phone call questionnaire interview to assess the long-term functional outcome of children aged 3 years and older.ResultsTotal transanal endorectal pull-through was performed in 61 patients. The mean age at the time of operation was 7.71 ± 8.26 months. The most common late complication was anal excoriation (19.7%). Of the patients, 61.5% had a normal to fair score, and the remaining 38% had a poor score in their functional outcome questionnaire. The majority had no social problems (65.4%), while 15.4% had problems causing varying degrees of social restrictions.ConclusionThe short-term outcomes of total transanal endorectal pull-through are found to be acceptable. In addition, the long-term functional outcome post total transanal endorectal pull-through was found to be satisfactory; however, longer follow-up studies with larger sample sizes are needed for more accurate functional outcome evaluation.

Surgical outcomes for patients with rectosigmoid hirschsprung disease who underwent transanal endorectal pull-through after 1 year of age

PurposeThis study aimed to compare the differences in postoperative complications and long-term bowel function outcomes between patients with rectosigmoid Hirschsprung disease (HD) who underwent transanal endorectal pull-through (TEPT) beyond infancy (age> 1 year of age) and those during infancy (≤ 1 year of age).MethodsAll patients with rectosigmoid HD at Beijing Children’s Hospital between January 2011 and December 2020 were analyzed retrospectively. They were divided into two groups based on age at TEPT: group A was defined as patients who performed TEPT beyond infancy (age>1 year of age), and group B as patients who performed TEPT during infancy (age ≤ 1 year of age). Clinical details were collected from medical records. Bowel function outcomes were assessed by the Rintala questionnaire (age ≥ 4 years).ResultsA total of 339 patients were included: 216 (63.7%) who operated with TEPT beyond infancy (group A) and 123 (36.3%) during infancy (group B). Regarding postoperative complications, all patients suffering anastomosis leakage following TEPT (7/216, 3.2%) occurred in group A, and the rate of anastomosis leakage in group A was significantly higher than in group B (3.2% vs. 0.0%, p = 0.044). 228 patients (228/327, 69.7%) completed the Rintala questionnaire. There was no significant difference in long-term bowel function outcomes between the two groups.ConclusionCompared with patients who performed TEPT during infancy, those beyond infancy are more likely to suffer anastomosis leakage. however, the long-term bowel function outcomes seem comparable.Type of StudyA retrospective single-center study.Level of evidenceIII.

Transanal Endorectal Pull-Through for Hirschsprung's Disease: Complications and Lessons from Our Practice and the Literature.

Hirschsprung's disease (HD) is a congenital disorder characterised by the absence of ganglion cells in the distal bowel, resulting in functional obstruction. The transanal endorectal pull-through (TEPT) procedure, a minimally invasive approach, aims to treat HD by removing the aganglionic segment. This study assessed the feasibility, safety, and efficacy of single-stage TEPT in paediatric patients, focusing on postoperative complications, bowel function, and quality of life. A retrospective cohort study was conducted on 150 children who underwent single-stage TEPT from January 2005 to December 2023 at the Medical University of Gdansk. Data were collected from medical records, including demographics, preoperative assessments, surgical details, postoperative management, and follow-up outcomes. Statistical analyses were performed using Microsoft Excel 365 and the programming language Python 3.12. The mean age at surgery was 13 months, with a male-to-female ratio of 2.75:1. The mean operative time was 129 min, and the mean hospital stay was seven days. Postoperative complications included anastomotic leak (4%), wound infections (15%), and enterocolitis (26%). Redo surgeries were required in 18% of cases due to persistent constipation and obstructive symptoms. This article includes a comprehensive review of the literature. TEPT demonstrates a favourable safety profile and efficacy in treating HD, though significant concerns include complications such as enterocolitis and the need for additional surgeries. Surgical expertise and thorough preoperative and postoperative management are crucial to optimising patient outcomes.

Minimally Invasive Surgery for Hirschsprung Disease: Current Practices and Future Directions.

Hirschsprung disease (HD) is a congenital disorder characterized by the absence of ganglion cells in the distal colon and rectum, leading to functional obstruction and severe constipation. Over the past decades, the surgical management of HD has significantly evolved, with minimally invasive surgery (MIS) techniques revolutionizing treatment approaches. This review explores recent innovations in MIS for HD, focusing on laparoscopic, transanal endorectal pull-through (TERPT), and robotic-assisted techniques. These approaches offer numerous advantages over traditional open procedures, including reduced surgical trauma, improved cosmesis, faster recovery times, and potentially lower complication rates. Laparoscopic surgery has become widely adopted, providing excellent visualization and precise dissection. TERPT has gained popularity for short-segment disease, offering a completely transanal approach with minimal scarring. Robotic-assisted surgery represents the cutting edge, enhancing surgical precision and dexterity. The review also examines emerging technologies and future directions, such as advanced imaging techniques, artificial intelligence applications, and potential developments in tissue engineering. While MIS techniques have shown promising outcomes, challenges remain in standardizing approaches, addressing long-segment disease, and optimizing long-term functional results. The future of HD surgery lies in personalized approaches that integrate genetic and molecular profiling with advanced surgical technologies. As the field continues to evolve, comprehensive long-term studies and efforts to improve access to specialized care will be crucial to further enhancing outcomes for patients with HD.

Outcomes following endorectal pull-through for Hirschsprung disease: a retrospective study

PurposeTo share our experience in the surgical management of patients with Hirschsprung disease (HD) using the trans-anal endorectal pull-through “Soave” technique.MethodsThe study included cases diagnosed as HD who were operated during the period 2008 through 2018. Cases of total colonic aganglionosis were excluded to be discussed in a separate report.ResultsThe study included 67 consecutive cases of HD. All included cases underwent trans-anal endorectal pull-through which was purely trans-anal in 31 (46%), while abdominal-assisted trans-anal endorectal pull-through was applied in the remaining (54%). Early postoperative complications included 2 cases of partial dehiscence at the colo-anal anastomosis; 1 of them deteriorated after re-exploration and unfortunately died. Twenty-six cases were available to assess functional outcomes after corrective surgery. Their age at follow-up ranged between 44 months and 17 years (mean = 78.8 months; median = 72 months). All cases achieved voluntary defecation. However, fecal soiling was a common finding after surgery for HD (69%). Constipation was another common postoperative finding (73%). Lastly, a history of attacks of postoperative enterocolitis was prevalent in 19 cases (73%), which ranged between 1 and 7 attacks usually in the first 2 years after the operation.ConclusionThe trans-anal endorectal pull-through provides an effective surgical treatment for Hirschsprung disease. The high prevalence of fecal soiling after surgery highlights the importance of long-term follow-up to provide the required support for these patients during adolescence and transition into adulthood.

Early Outcomes of Hirschsprung's Disease after Definitive Surgery: A Ten-Year Experience.

This study aimed to examine the characteristics of Hirschsprung's Disease (HD) in patients aged<18 who underwent surgical procedure at Dr. Zainoel Abidin (RSUDZA) General Hospital, Banda Aceh, Indonesia, between January 2010 and December 2020. This retrospective study collected and analyzed data from medical records of 18-yearold or younger children (n = 180) diagnosed with HD at RSUDZA. The surgical procedures included the Duhamel procedure, Soave procedure, the Soave Transanal Endorectal Pull-through (TEPT) procedure, and the Swenson TEPT procedure. Early outcomes of the surgery were then compared between males and females. The comparrative analysis was determined based on Chisquare analysis, where p&#60; 0.05 was considered significant. There were 111 (61.7%) male patients and 69 (38.3%) female patients, with a mean age of 15.2 months. The Soave TEPT is the most frequently performed procedure (91.7%). Emerging clinical manifestations include constipation (176; 97.8%) and soiling (171; 95%). Preoperative barium enema and postoperative pathological examination confirmed that almost all patients (99.4%) had an aganglionic segment confined to the rectosigmoid area. The average length of operation was 69.7 ± 65 minutes and average bleeding time was 5.4 ± 34 mL. The average discharge time was 3.3 ± 73.3 days. No significant difference was found in post-surgery complications between males and females (p&#60;0.5). The immediate complications were not associated with surgical methods (p = 0.83). Our descriptive study has suggested the Soave TEPT technique as appropriate to manage HD.

Duhamel and transanal endorectal pull-throughs for Hirschsprung disease: a Bayesian network meta-analysis

BackgroundTo comprehensively compare the effects of open Duhamel (OD), laparoscopic-assisted Duhamel (LD), transanal endorectal pull-through (TEPT), and laparoscopic-assisted endorectal pull-through (LEPT) in Hirschsprung disease.MethodsPubMed, Embase, Cochrane Library, Web of Science, CNKI, WanFang, and VIP were comprehensively searched up to August 4, 2022. The outcomes were operation-related indicators and complication-related indicators. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence. Network plots, forest plots, league tables and rank probabilities were drawn for all outcomes. For measurement data, weighted mean differences (WMDs) and 95% credibility intervals (CrIs) were reported; for enumeration data, relative risks (RRs) and 95%CrIs were calculated.ResultsSixty-two studies of 4781 patients were included, with 2039 TEPT patients, 1669 LEPT patients, 951 OD patients and 122 LD patients. Intraoperative blood loss in the OD group was more than that in the LEPT group (pooled WMD = 44.00, 95%CrI: 27.33, 60.94). Patients lost more blood during TEPT versus LEPT (pooled WMD = 13.08, 95%CrI: 1.80, 24.30). In terms of intraoperative blood loss, LEPT was most likely to be the optimal procedure (79.76%). Patients undergoing OD had significantly longer gastrointestinal function recovery time, as compared with those undergoing LEPT (pooled WMD = 30.39, 95%CrI: 16.08, 44.94). The TEPT group had significantly longer gastrointestinal function recovery time than the LEPT group (pooled WMD = 11.49, 95%CrI: 0.96, 22.05). LEPT was most likely to be the best operation regarding gastrointestinal function recovery time (98.28%). Longer hospital stay was observed in patients with OD versus LEPT (pooled WMD = 5.24, 95%CrI: 2.98, 7.47). Hospital stay in the TEPT group was significantly longer than that in the LEPT group (pooled WMD = 1.99, 95%CrI: 0.37, 3.58). LEPT had the highest possibility to be the most effective operation with respect to hospital stay. The significantly reduced incidence of complications was found in the LEPT group versus the LD group (pooled RR = 0.24, 95%CrI: 0.12, 0.48). Compared with LEPT, OD was associated with a significantly increased incidence of complications (pooled RR = 5.10, 95%CrI: 3.48, 7.45). Patients undergoing TEPT had a significantly greater incidence of complications than those undergoing LEPT (pooled RR = 1.98, 95%CrI: 1.63, 2.42). For complications, LEPT is most likely to have the best effect (99.99%). Compared with the LEPT group, the OD group had a significantly increased incidence of anastomotic leakage (pooled RR = 5.35, 95%CrI: 1.45, 27.68). LEPT had the highest likelihood to be the best operation regarding anastomotic leakage (63.57%). The incidence of infection in the OD group was significantly higher than that in the LEPT group (pooled RR = 4.52, 95%CrI: 2.45, 8.84). The TEPT group had a significantly increased incidence of infection than the LEPT group (pooled RR = 1.87, 95%CrI: 1.13, 3.18). LEPT is most likely to be the best operation concerning infection (66.32%). Compared with LEPT, OD was associated with a significantly higher incidence of soiling (pooled RR = 1.91, 95%CrI: 1.16, 3.17). Patients with LEPT had the greatest likelihood not to develop soiling (86.16%). In contrast to LD, LEPT was significantly more effective in reducing the incidence of constipation (pooled RR = 0.39, 95%CrI: 0.15, 0.97). LEPT was most likely not to result in constipation (97.81%). LEPT was associated with a significantly lower incidence of Hirschprung-associated enterocolitis (HAEC) than LD (pooled RR = 0.34, 95%CrI: 0.13, 0.85). The OD group had a significantly higher incidence of HAEC than the LEPT group (pooled RR = 2.29, 95%CrI: 1.31, 4.0). The incidence of HAEC was significantly greater in the TEPT group versus the LEPT group (pooled RR = 1.74, 95%CrI: 1.24, 2.45). LEPT was most likely to be the optimal operation in terms of HAEC (98.76%).ConclusionLEPT may be a superior operation to OD, LD and TEPT in improving operation condition and complications, which might serve as a reference for Hirschsprung disease treatment.

Comparison between Anal Dilatation Protocols Following an Endorectal Pull-through for Hirschsprung Disease

Objective: The purpose of this study was to compare the mechanical obstruction rate following a transanal endorectal pull-through (TERPT) in patients with Hirschsprung disease, between regular anal dilatation (AD) and selective anal dilatation (NAD) which meant that dilatation was only performed when an obstructive symptom occurred. Materials and Methods: A retrospective chart review of patients with Hirschsprung disease who underwent TERPT/abdominal assisted TERPT at Siriraj Hospital between January 2009 and December 2021 was carried out. It was the surgeon’s preference that the dilatation protocols between the 2 groups (AD or NAD) were assigned. Mechanical obstructions included evidence of stricture, a clinical symptom of constipation, presence of Hirschsprung-associated enterocolitis (HAEC), and/or requirement of re-operation. Results: In total, 132 patients were included in this study, including 55 cases in the AD group (41.7%) and 77 cases in the NAD group (58.3%). Postoperative mechanical obstructions occurred in 84 patients (63.6%). Among the mechanical obstructions, there were 35 strictures (26.5%), 26 constipation (19.7%), 40 HAECs (30.3%), and 6 reoperation (4.5%). The mechanical obstruction rates in the AD [33/55 (60.0%)] and NAD [51/77 (66.2%)] groups were not significantly different (p = 0.582). The AD group was of a significantly younger age (p = 0.022) and lower body weight (p = 0.048) than the NAD group; however, a younger age and lower body weight were not significantly related with any of the obstructive complications. AD had a rate of anastomosis/cuff stricture [13/55 (23.6%)] similar to NAD [22/77 (28.6%)] (p = 0.665).

Concurrence of Hirschsprung disease and annular pancreas: a rare case report

Hirschsprung’s disease (HD) and annular pancreas are both uncommon congenital gastrointestinal malformations. Although additional abnormalities are associated with 18% of HD cases, there is limited evidence of concomitant HD and annular pancreas. We present a full-term, two-day-old male with abdominal distended, and failure to pass first stool after 3 days of observation and rectal washout the abdominal X-rays showed a double bubble appearance. Intraoperative finding, the patient had pancreas annulare (PA). Colonic aganglionosis was discovered using full-thickness rectal biopsies (FTRB). At the age of seven months, a transanal endorectal pull-through was performed without complications. Although the diagnosis of these conditions might be difficult due to their clinical similarities, appropriate diagnosis, and surgical management are possible and can dramatically minimize morbidity and death in the newborn.

Comparison of the quality of life of children with congenital megacolon (Hirschsprung’s disease) post transanal endorectal pull-through with other children's surgical cases in the 5-7-years age group at Moewardi Hospital Surakarta

Background: Congenital megacolon (Hirschsprung's disease) is caused by intestinal innervation abnormalities, due to failure of neuroblast migration from the proximal to the distal intestine so there is no nerve innervation in the distal intestine and causes functional ileus and hypertrophy and excessive intestinal distension. The classic triad of clinical features in neonates is late meconium expulsion, namely more than the first 24 hours, green vomiting, and an enlarged stomach. Management of congenital megacolon is divided into two, namely non-surgical treatment to overcome complications that may occur and to improve the general condition until definitive surgery and surgical treatment namely transabdominal approach (TAB), consisting of Swenson, Duhamel, Rehbein, and Soave, and transanal endorectal pull-through (TEPT). The advantages of TEPT include better cosmetic effects and shorter hospital stays. Quality of life (QoL) is a subjective perception of a person's well-being regarding levels in his life, which includes physical, social, and psychological conditions. Methods: This research is observational analytical research with a cross-sectional approach conducted at RSUD Dr. Moewardi Surakarta during August - September 2022. Results: Patients with congenital megacolon (Hirschsprung disease) after TEPT have a worse QoL than patients without congenital megacolon (p value &lt;0.05). All components of the pediatrics quality of life questionnaire (PedsQLTM) are influenced by the patient's condition (p value &lt;0.05). Conclusions: The poor quality of life should increase awareness of the importance of immediate treatment. Difficulty defecating, diarrhea, and abdominal pain can reduce the patient's QoL after TEPT. Family dynamics and support must be prioritized to improve the QoL.

Incidence of Infection-related Complications and Optimal Saline Irrigation Volume for Preoperative Bowel Preparation to Reduce Postoperative Infections in Hirschsprung’s Disease

Objective: The purpose of this study was to find incidence of infection-related complications and the optimal volume and duration (days) of rectal NSS irrigation that would result in the low post-operative complications following transanal endorectal pull-through (TERPT) in patients with Hirschprung’s disease. Materials and Methods: We conducted a retrospective chart reviews of 131 patients diagnosed with Hirschsprung’s disease who underwent TERPT at Siriraj Hospital between January 2006 and December 2020. Results: Infection-related complications were observed in 23(17.6%) patients, comprising 22(16.8%) cases of anastomotic strictures, 3(2.3%) cases of anastomotic leakages, and 2(1.5%) cases of intraabdominal collections. The median (Q1, Q3) volume of NSS irrigation (ml/kg/day) for those without complications (38.1 (33.9,50)) and those with complications (39.5 (35,45)) was statistically identical (p = 0.945). Similary, the median duration of for both groups was the same (p = 0.854). The mean (SD) volume of irrigated NSS in those with leakage (55.6 (32.7)) and those without leakage (44.3 (17.9)) showed no statistically significant difference (p = 0.291). Patients with post-operative stricture received the same amount of irrigated NSS (40.7 (11.9)) as those without stricture (45.4 (19.2)) (p = 0.138). Similarly, those with hyponatremia received the same amount of irrigated NSS as those without hyponatrema (p = 0.475). Conclusion: The volume of rectally irrigated NSS did not correlate with infection-related complications such as anastomotic leakage, stricture and intraabdominal collection. However, this study observed a low complication rate, thus, future research should cover a larger population.

Peri-anal infiltration versus caudal block for multimodal analgesia in paediatric patients with Hirschsprung's disease undergoing transanal endorectal pull-through procedure: A randomised trial.

Transanal endorectal pull-through (TERPT) is a standard procedure for managing paediatric patients with Hirschsprung's disease (HD). This study aimed to evaluate peri-anal infiltration versus caudal block as a part of multimodal analgesia for paediatric patients with HD undergoing the TERPT procedure. This randomised trial included 60 patients of both genders, aged 6 to 18 months who underwent the TERPT procedure under general anaesthesia. The patients were randomly assigned into two groups to receive either peri-anal infiltration or caudal block with 1 ml/kg bupivacaine 0.25% and dexmedetomidine 1 µg/kg in 0.5 ml normal saline. The primary outcome was the time to the first rescue analgesia. The secondary outcomes were the total consumption, the frequency of nalbuphine administration as rescue analgesia within 24 hours and the level of postoperative sedation. The time to first rescue analgesia was significantly shorter in the peri-anal infiltration group versus the caudal block group (median [interquartile range] 10 [7.5-12.5] h versus 16 [13.5-18.5] h, respectively, P = 0.008). The frequency of administration and the total dose of nalbuphine was significantly higher in the peri-anal infiltration group (P = 0.003 and 0.013, respectively). The sedation score was significantly higher in the caudal block group postoperatively. For paediatric patients undergoing the TERPT procedure, peri-anal infiltration was less effective than caudal block in terms of the duration of postoperative analgesia. However, both techniques were comparable during the first 6 hours postoperatively.

Clinical outcomes evaluation of congenital megacolon (Hirschsprung disease) short segment type after transanal endorectal pull through at Moewardi Hospital Surakarta

Background: Congenital megacolon occurs in 1 in 5000 live births, with an estimated 1200 cases annually in Indonesia, predominantly affecting males. Mortality and morbidity in these patients can be reduced through improved diagnosis, neonatal care, surgical techniques, and enterocolitis management. The transanal endorectal pull through (TEPT) procedure, a minimally invasive surgery, is the common definitive treatment for congenital megacolon, performed even in neonates. However, TEPT can lead to post-operative anorectal dysfunction, necessitating assessment through fecal continence evaluation. The aims of this study is to understand of the clinical outcome congenital megacolon short segment type after TEPT procedure at Moewardi Hospital, Surakarta. Methods: The study is a cross sectional descriptive analysis in patients with congenital megacolon short segment type who have received TEPT treatment at Moewardi Hospital Surakarta from 2010 until 2022. Results: Among the patients, 18.9% exhibited normal anorectal function, 54.1% had good continence, 24.3% had moderate continence, and 2.7% experienced incontinence. Surgery age was mostly between 1 and 12 months (64.9%), with 62.2% achieving good continence. At the 1-5-year follow-up, 48.6% had good continence. Among primarily male patients (86.1%), 43.2% had good continence. Strong correlation (Pearson Chi-square score: 0.001) confirmed the relationship between age at the time of surgery and anorectal function outcomes. Conclusions: TEPT yielded favorable anorectal function outcomes in short-segment congenital megacolon patients, with surgery age significantly impacting these outcomes. This study supports the hypothesis that surgery age influences anorectal function outcomes after TEPT at Moewardi Hospital, Surakarta.

Comparison of the Duhamel Procedure and Transanal Endorectal Pull-through Procedure in the Treatment of Children with Hirschsprung's Disease: A Systematic Review.

Studies comparing the Duhamel and TERPT procedures were included until 22 July 2023. R software (version 4.3.0) was used to perform the meta-analysis. Ten studies with a sum of 496 patients were included. The length of postoperative hospital stay and incidence of postoperative constipation were longer and higher after the Duhamel procedure than the TERPT procedure (p < 0.0001 and p = 0.0041, respectively). The incidence of postoperative anastomotic stricture was higher after the TERPT procedure than the Duhamel procedure (p = 0.0015). No significant differences were found in the incidence of postoperative fecal continence, fecal incontinence/soiling, anastomotic leak, or ileus between these two procedures. The operation time seemed to be similar for both procedures, but it became longer for the Duhamel procedure than the TERPT procedure after sensitivity analysis. While the incidence of postoperative enterocolitis seemed to be higher after the TERPT procedure, it became similar for both procedures in the subgroup analysis. The Duhamel procedure seems to be associated with a longer length of postoperative hospital stay, a higher incidence of postoperative constipation, and a lower incidence of postoperative anastomotic stricture than the TERPT procedure. However, the effect of these two procedures on the operation time and the incidence of postoperative enterocolitis remains unclear.

Post-surgical Outcomes of Different Surgical Techniques in Hirschsprung's Disease: A Literature Review.

Hirschsprung's disease (HD) is a rare condition that affects newborns and is characterized by the lack of ganglion cells in the colon. Typical symptoms include difficulty passing stool, vomiting, and trouble feeding. Various surgical methods are available to manage the condition. The aim of the study is to investigate and compare the post-surgical outcomes of different surgical techniques used in the treatment of HD. A thorough literature search was conducted using various electronic databases to identify relevant studies to be referred to.Double-blinded screening of the identified articles led to the final selection of 40 out of 440 HD, including transanal endorectal pull-through (TERPT), laparoscopic approaches, and modified techniques.Several studies have investigated surgical procedures for HD, including TERPT, laparoscopic methods, and modified techniques. These have shown positive outcomes, with fewer complications, improved bowel function, and favorable cosmetic results. Individual patient characteristics and surgeon expertise should guide procedure selection.Surgery for HD aims to restore normal bowel function, but post-surgical outcomes can include constipation or fecal incontinence. Complications like enterocolitis, anastomotic stricture, and sphincter damage may occur. Laparoscopic approaches have shorter hospital stays. However long-term follow-up is essential to assess quality of life, psychological well-being, and potential side effects.

Long-term bowel function after single-stage transanal endorectal pull-through in neonatal patients with Hirschsprung disease.

The aim of this study was to assess long-term outcomes of neonatal patients with Hirschsprung disease (HD) after single-stage transanal endorectal pull-through (TEPT) and to explore the predictive factors contributing to subnormal bowel function. Patients aged > 3years operated for HD with TEPT during neonatal period between 2007 and 2019 answered the bowel function score (BFS) questionnaire. The patients were retrospectively divided into two groups according to whether they had normal bowel function. The clinical variables were compared between the subnormal and normal BFS groups. Univariate and multivariable logistic regression analysis were performed to identify the predictive factors contributing to subnormal bowel function. A total of 160 children (71.7%) were included in this study, with mean follow-up time of 7.3years (range 3.0-15.1years). The level of aganglionosis were determined to be the short-segment (124/160, 77.5%), long-segment (33/160, 20.6%), and TCA (3/160, 1.9%). One hundred and thirty-four patients (83.8%) had a BFS ≥ 17, and 26 patients (16.2%) with subnormal bowel function (BFS < 17). Univariate and multivariate logistic regression analysis showed that level of aganglionosis with long-segment or TCA and postoperative hospital stay > 8.5days were independent risk factors with OR of 3.213 (1.252, 8.246) and 3.813 (1.371, 10.606) for subnormal BFS, respectively. Most HD patients who underwent one-stage TEPT in the neonatal period have favorable long-term results, and the level of aganglionosis with long-segment or TCA and long postoperative hospital stay may be closely related to subnormal bowel function.

Comparison of clinical results of Transanal Endorectal Pull-Through of the colon with and without laparoscopic assistance in children with Hirschsprung’s disease

Introduction. Techniques of Transanal Endorectal Pull-Through (TEPT) with and without laparoscopic assistance have been widely used in pediatric surgery for correction of Hirschsprung’s disease (HD) in children with. Many clinics in their studies have noted the positive features of this approach compared to classical methods, but the long-term results after such operations in children are still debated. Purpose - to study and compare the clinical results of TEPT with and without laparoscopic assistance in children with HD. Materials and methods. We analyzed the experience of TEPT approach with laparoscopy (n=65 (29.41%)) and without laparoscopic assistance (n=144 (70.59%)) in childreb for correction of HD. For confirmation diagnosis we used the results of general clinical and special procedures (barium enema, anomanometry, histological, determination of acetylcholesterase activity). Results. Overall, among 55 (26.32%) of 209 patients who underwent TEPT, postoperative in long term follow up we found intestinal problems like - moderate stenosis of the colo-anal anastomosis without incontinence 4 (1.91%), constipation 9 (4.31%), partial faecal incontinence 20 (9.57%) and enterocolitis (EC) 22 (10.53%). There was no significant difference in the clinical results of TEPT with laparoscopy and without laparoscopic assistance in our patients. After TEPT without laparoscopic assistance, 6 (4.17%) of 144 patients had constipation, 11 (7.64%) had partial fecal incontinence, and 16 (11.11%) had enterocolitis (EC). And among 65 children after TEPT with laparoscopy, 3 (4.62%) patients were diagnosed with constipation, 9 (13.85%) with partial fecal incontinence and 6 (9.23%) with EC. All children with postoperative intestinal problems were treated conservatively. There was no need for redo surgical interventions in these patients. Conclusions. The technique of TEPT with laparoscopy and without laparoscopic assistance is a modern method of surgical correction of HD, which has significant technical advantages compared to other existing methods. In 26.32% of children with HD who were operated by the TEPT method, persistent intestinal problems continue in the long term follow-up period. The research was carried out in accordance with the principles of the Declaration of Helsinki. The research protocol was approved by the Local Ethics Committee of all institutions mentioned in the work. Informed consent of the children’s parents was obtained for the research. No conflict of interests was declared by the authors.

Early Surgical Complications Following Transanal Endorectal Pull-through for Hirschsprung’s Disease

Objective: The purpose of this study was to examine factors affecting early complications following transanal endorectal pull-through (TERPT) in patients with Hirschprung’s disease. Materials and Methods: Retrospective chart reviews of patients with Hirschsprung’s disease who underwent TERPT/ abdominal assisted TERPT at Siriraj Hospital between January 2009 and December 2019 was carried out. . Results: The overall complication rate was 26% (43/163). The complications were as follows: 14 cases of anastomotic strictures (32.6%), five cases of abscess at anastomosis (11.6%), and three cases of anastomotic leakages (7.0%). In regards to preoperative bowel preparation, when comparing those with and those without post-operative complications, the amount of NSS for rectal irrigation (ml/Kg), duration required (days), and duration of changed diet (days) were the same. Colostomy prior to a pull-through operation could not prevent post-operative complications following endorectal pull-through (p = 1.000). The incidences of early complications following TERPT and abdominal assisted TERPT was the same (p = 0.344). Abdominal assisted TERPT had a higher incidence (4%) of anastomotic leakages whereas TERPT had a higher rate of anastomosis strictures (12%) compared to o abdominal assisted TERPT (5%). The higher the transitional zone, the higher the complication rate. Anastomotic leakages, the most serious complication, rarely occurred following TERPT in the low transitional zone. Conclusion: There was no significant risk factor associated with early surgical complications following TERPT. Abdominal assisted TERPT should be selected properly according to the level of transitional zone. The complications correlate with whether a perfect pull-through operation could be performed or not.

Comparison between two minimally invasive techniques for Hirschsprung disease: transanal endorectal pull-through (TERPT) versus laparoscopic-TERPT.

Surgical treatment for Hirschsprung disease (HD) has recently evolved into different minimally invasive techniques. The aim of the present study is to compare results from two different minimal invasive approaches, transanal endorectal pull-through (TERPT) and laparoscopic-assisted endorectal pull-through (LA-TERPT). Patients have been divided into two groups according to surgical technique. Data of HD patients treated by TERPT and those treated by LA-TERPT, respectively, performed at two different centers from January 2007 to December 2017, were retrospectively collected. Patients with aganglionosis confined to the recto-sigmoid colon with a minimum follow-up period of 4years have been included. Demographic, clinical, surgical and functional outcome data were reviewed for each group using Chi-square and Fisher tests (statistical differences were considered for p < 0.05). Among patients treated for HD in the two centers during the study period, 65 met the inclusion criteria (37 TERPT group and 28 LA-TERPT group). No differences regarding demographic and clinical data were observed between the two groups. Operative time was longer in the LA-TERPT group (p < 0.001). Time to start oral feeding was faster in the TERPT group while hospital stay was similar between the two groups. Three patients of the TERPT group required an additional abdominal approach. The rate of early complications was higher in the TERPT group. Long-term bowel function was assessed in 31 patients for the TERPT group and 24 patients for the LA-TERPT group. Outcomes showed that the bowel functional outcome was good (BFS ≥ 17) in 55% (n = 17) of TERPT group and 54% of LA-TERPT group (p = 0.97), moderate (BFS 12 to 16) in 16% (n = 5) and 33% (n = 8), respectively (p = 0.24), and poor in 29% (n = 9) and 13% (n = 3), respectively (p = 0.23). Both TERPT and LA-TERPT techniques should be considered safe and feasible for the treatment of HD patients. TERPT patients present faster time to return to normal bowel function while LA-TERPT patients have slightly lower incidence of postoperative complications. Long-term functional outcomes are similar between the two groups. III.

Outcome of Transanal Endorectal Pull-Through in Patients with Hirschsprung's Disease.

Transanal endorectal pull-through (TERPT) has become one of the preferred treatments for Hirschsprung's disease (HD) in our setting. This report aims to evaluate the current outcome of TERPT in the setting. A retrospective review of 71 children who had TERPT for histologically-confirmed HD in 11 years (2006-2017) in Nigeria. There were 48 boys and 23 girls; aged 3 days-12 years at initial presentation (median = 10 months). Three (4.2%) patients had associated anomalies (duodenal atresia; anorectal malformation and sensorineural deafness with hypopigmented skin patches each). Age at TERPT was 2 months to 15 years (median = 3 years), with surgery waiting time of 1 month-14.9 years (median = 18 months). Sixty-six (93.0%) patients had rectosigmoid, four (5.6%) patients had long segment and one (1.4%) had total colonic disease. Five (7.0%) patients with large megacolon and one (1.4%) with the total colonic disease had assisted abdominal resection of the colon at TERPT. Seventeen (23.9%) patients had post-operative complications, including post-operative enterocolitis 8 (11.3%); anastomotic dehiscence 3 (4.2%); retained aganglionic segment 2 (2.8%); anastomotic stenosis 2 (2.8%), resulting in prolonged hospital stay (P = 0.0001; range = 1-30 days; median = 5 days). The mortality rate was 4.2% (3) from malignant hyperthermia in one patient and in 2 patients, the cause of mortality was unclear. Patients were followed up for 3-6 years (median = 3.5 years). Bowel movement stabilised to 2-4 times daily by 6 weeks after surgery. TERPT is a safe treatment for HD in this setting with good short-term outcomes. Longer follow-up is necessary to further evaluate the long-term bowel movement outcomes.!
