CHILDREN (BASEL, SWITZERLAND) 2024; 11:1059. [PMID: 39334591 PMCID: PMC11430751 DOI: 10.3390/children11091059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2024] [Revised: 08/21/2024] [Accepted: 08/25/2024] [Indexed: 09/30/2024]
Abstract
BACKGROUND/OBJECTIVES 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Plast Reconstr Surg 2024; 154:100e-111e. [PMID: 37537729 PMCID: PMC11195934 DOI: 10.1097/prs.0000000000010956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 07/26/2023] [Indexed: 08/05/2023]
Abstract
BACKGROUND Despite the increasing popularity of various materials for ischemia-reperfusion (I/R) injury mitigation, research on botulinum toxin type A (BoNTA) remains limited. This study assesses BoNTA's efficacy in protecting flaps from I/R injury by inhibiting the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase system and reducing reactive oxygen species (ROS) production. METHODS Seventy-six Sprague-Dawley rats were studied. We examined the effects of BoNTA on superoxide production in four rats using a lucigenin-enhanced chemiluminescence assay (LECL). Another group of 60 rats had their superficial inferior epigastric artery (SIEA) flaps treated with either BoNTA or saline and clamped for 0, 1, and 4 hours before reperfusion. Flap survival and histological outcomes were assessed five days post-operation. ROS production in SIEA flaps and femoral vessels was analyzed in 12 additional rats, post-I/R injury. RESULTS The LECL results showed that the BoNTA group had significantly lower superoxide production compared to controls, with notable reductions at 4 hours. While no significant differences were noted at the 0 and 1-hour marks, the 4-hour mark showed significant protective effects in BoNTA-treated groups. The survival rate was 90% for BoNTA-treated rats versus 60% for controls ( P = 0.028). Significant reductions in ROS were also observed in the 4-hour I/R group. CONCLUSIONS BoNTA effectively protects against I/R injury by inhibiting the NADPH oxidase system and reducing ROS levels. These results support further investigation into the specific mechanisms of NADPH oxidase inhibition by BoNTA and its potential clinical applications, given its safety profile. CLINICAL RELEVANCE STATEMENT The findings from the present study are expected to provide a basis for clinical studies regarding this use of BoNTA.

Abstract
BACKGROUND Hirschsprung-associated enterocolitis (HAEC) is the most common cause of morbidity and mortality amongst patients with Hirschsprung disease (HD); rectal Botulinum toxin (Botox) has been reported a possible prevention strategy. We aimed to evaluate our institution's historic cohort of HD patients, first to determine our incidence of HAEC and second to begin assessing the effect of Botox on HAEC incidence. METHODS Patients with HD seen at our institution between 2005 and 2019 were reviewed. Incidence of HD and frequencies of HAEC and Botox injections were tallied. Associations between initial Botox treatment or transition zone and HAEC incidence were evaluated. RESULTS We reviewed 221 patients; 200 were included for analysis. One hundred thirteen (56.5%) patients underwent primary pull-through at a median age of 24 days (IQR 91). Eighty-seven (43.5%) patients with initial ostomy had their intestinal continuity reestablished at a median of 318 days (IQR 595). Ninety-four (49.5%) experienced at least one episode of HAEC and 62 (66%) experienced multiple episodes of HAEC. Nineteen (9.6%) patients had total colonic HD and had an increased total incidence of HAEC compared to patients without total colonic HD (89% vs 44%, p < 0.001). Six (2.9%) patients received Botox injections at the time of pull-through or ostomy takedown; one experienced an episode of HAEC (versus 50.7% of the patients who were confirmed to have not received Botox injections at their surgery, p = 0.102). CONCLUSION Further prospective study on Botox's effect on Hirschsprung-associated enterocolitis is required and is the next step in our investigation. LEVEL OF EVIDENCE Level III.

Abstract
Children with Hirschsprung disease have postoperative long-term sequelae in defecation that contribute to morbidity and mortality and significantly impact their quality of life. Pediatric patients experience ongoing long-term defecation concerns, which can include fecal incontinence (FI) and postoperative obstructive symptoms, such as constipation and Hirschsprung-associated enterocolitis. The American Pediatric Surgical Association has developed guidelines for management of these postoperative obstructive symptoms and FI. However, the evaluation and management of patients with postoperative defecation problems varies among different pediatric gastroenterology centers. This position paper from the Neurogastroenterology & Motility Committee of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition reviews the current evidence and provides suggestions for the evaluation and management of postoperative patients with Hirschsprung disease who present with persistent defecation problems.

Abstract
PURPOSE Radical surgery is the most effective treatment for Hirschsprung's disease. However, some children still have symptoms of intestinal dysfunction such as constipation, abdominal distension, and recurrent enterocolitis after operation. The purpose of this study was to evaluate treatment outcomes of postoperative intestinal dysfunction in children with Hirschsprung's disease by using the principle of "anorectal balance". METHODS The clinical data of postoperative intestinal dysfunction in children with Hirschsprung's disease in the single treatment group from July 2019 to July 2021 were retrospectively analyzed. All the enrolled children underwent botulinum toxin injection (2.5 U/kg); 3 to 6 months later, the injection was performed again; the children who had received more than two botulinum toxin injections underwent the internal sphincter myectomy. Anorectal manometry was performed routinely after operation, and abdominal distension and defecation were recorded. RESULTS A total of thirty children with postoperative intestinal dysfunction underwent radical surgery for Hirschsprung's disease were included in this study. Symptoms of constipation, abdominal distension and enterocolitis were improved after botulinum toxin injections in most children compared to before surgery (P < 0.01). After re-injection of botulinum toxin in twelve children, the frequency of defecation increased, the anal resting pressure decreased, and the clinical symptoms were relieved again (P < 0.05). Eleven children underwent internal sphincter myectomy, and the symptoms of constipation, abdominal distension and enterocolitis were significantly improved after the operation (P < 0.01). CONCLUSION Botulinum toxin injection and internal sphincter myectomy based on the principle of "anorectal balance" can effectively reduce the resting pressure of the anus and relieve intestinal dysfunction, and have satisfactory clinical effect.

[PMID: 32739102 DOI: 10.1016/j.jpedsurg.2020.06.044] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 06/21/2020] [Accepted: 06/26/2020] [Indexed: 01/16/2023]
Abstract
BACKGROUND Functional constipation (FC) is a common pediatric healthcare problem worldwide. Obstructed defection syndrome (ODS) is frequently presented with an inability to coordinate the bowel movement with pelvic floor muscles. Botulinum toxin (BT) intraanal sphincteric injection can improve the obstructed defecation by relaxing the anal sphincter and reducing the required force to propel the stools. PURPOSE This study aimed to compare the changes in Rintala scores (as a mean of assessing defecatory function), in children with FC and ODS, managed by BT injection, bowel management program (BMP), and senna based laxatives (SBL), versus a control group managed by BMP and SBL only. METHODS Prospective randomized controlled study, started at December 2017 on 40 pediatric patients, divided into 2 equal groups (group A: managed by BMP and SBL, group B: like group A with once intraanal sphincteric BT injection) suffering from FC, ODS, with contrast enema showing persistence of ≤90 rectoanal angle (RAA) even with trials of defecation. Patients were excluded if they have neuromuscular abnormalities, hypothyroidism, previous colorectal or anal surgery. Rintala score was assessed before treatment, at 2 months, and 6 months after management. RESULTS The study included 18 females (45%) and 22 males (55%). Group A had equal gender distribution and mean age of 6.9 years, while group B had 12 males with mean age of 7.35 years. The mean follow up period was 11.35 months in group A and 11.6 months in group B. Mean Rintala scores of both groups at initial presentation, 2 months and 6 months follow up were: group A: 9.10, 9.40, 10.90; group B: 9.30, 10.70, 11.05 respectively, and showed no statistically significant difference (p value: 0.884, 0.294, 0.923 respectively). No complications were detected from BT injection like allergic reactions, neuromuscular urinary or lower limbs disturbances. CONCLUSION Intraanal sphincteric injection of botulinum toxin by the mentioned technique and dose, did not result in additional defecatory functional improvement (when assessed by Rintala score) over the routine protocol (using bowel management program and laxatives) of managing functional constipation with obstructed defecation. ANNOUNCEMENT: a preliminary report of this work was presented in the 34th Egyptian pediatric surgery association (EPSA) meeting in Cairo in November 2019. TYPE OF STUDY Treatment/prospective study.

Abstract
BACKGROUND Our objective is to describe the prevalence of patients with internal anal sphincter achalasia (IASA) without Hirschsprung disease (HD) among children undergoing anorectal manometry (ARM) and their clinical characteristics. METHODS We performed a retrospective review of high-resolution ARM studies performed at our institution and identified patients with an absent rectoanal inhibitory reflex (RAIR). Clinical presentation, medical history, treatment outcomes, and results of ARM and other diagnostic tests were collected. We compared data between IASA patients, HD patients, and a matched control group of patients with functional constipation (FC). KEY RESULTS We reviewed 1,072 ARMs and identified 109 patients with an absent RAIR, of whom 28 were diagnosed with IASA. Compared to patients with FC, patients with IASA had an earlier onset of symptoms and were more likely to have abnormal contrast enema studies. Compared to patients with HD, patients with IASA were more likely to have had a normal timing of meconium passage, a later onset of symptoms, and were diagnosed at an older age. At the latest follow-up, the majority of patients diagnosed with IASA (54%) were only using oral laxatives. Over half of patients with IASA had been treated with anal sphincter botulinum toxin injection, and 55% reported a positive response. CONCLUSIONS AND INFERENCES Patients diagnosed with IASA may represent a more severe patient population compared to patients with FC, but have a later onset of symptoms compared to patients with HD. They may require different treatments for their constipation and deserve further study.
