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

BACKGROUND: 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. METHODS: Patients aged > 3 years 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. RESULTS: A total of 160 children (71.7%) were included in this study, with mean follow-up time of 7.3 years (range 3.0-15.1 years). 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 > 8.5 days were independent risk factors with OR of 3.213 (1.252, 8.246) and 3.813 (1.371, 10.606) for subnormal BFS, respectively. CONCLUSION: 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.

Indocyanine green fluorescence imaging localization: A helpful addition to laparoscopic dissection and division of rectourethral fistulae.

BACKGROUND: Rectourethral fistulae (RUF) are the most prevalent type of anorectal malformations in boys, with various surgical treatment methods investigated in recent years. Currently, research is focused on preventing urethral damage or urethral diverticulum formation caused by imprecise dissection during the laparoscopically assisted anorectal pull-through (LAARP) technique. This study aimed to determine the efficacy of indocyanine green (ICG) fluorescence imaging to improve the localization and separation of the RUF during laparoscopic surgery. METHODS: ICG was intrarectally injected through a pre-inserted gastric tube at the distal enterostomy port to locate the fistula. This retrospective analysis included children with RUF who were treated surgically with ICG fluorescence imaging localization-assisted LAARP between January and June 2022. We investigated the patient demographics, perioperative conditions, and subsequent follow-up results. RESULTS: Four patients underwent ICG-assisted LAARP. Their median age was 80 days (range, 63-120) and the median duration of each procedure was 145 min (range, 120-165). Postoperatively, the duration of catheter retention and hospital stay was eight days. The children's prognosis was based on the follow-up outcomes of gastrointestinal, urinary tract function, and imaging examination. None of the included patients was diagnosed with urinary diverticulum, urinary tract injury, anal stricture, or rectal prolapse. CONCLUSIONS: Injection of ICG at the end of the rectum during LAARP surgery is a feasible adjunct for locating the RUF, providing a greater degree of accuracy for laparoscopic separation and resection of fistulae, thereby decreasing the risk of urological complications.

One-stage transanal endorectal pull-through for Hirschsprung disease: experience with 229 neonates.

OBJECTIVE: To evaluate the safety and efficacy of transanal endorectal pull-through (TEPT) and the long-term outcomes in newborns with Hirschsprung disease (HD). METHODS: A total of 229 newborns with HD underwent one-stage TEPT between 2007 and 2020, and the diagnoses were confirmed by rectal biopsy. The perioperative clinical course for all patients was reviewed, and the postoperative short- and long-term outcomes were assessed. RESULTS: A total of 229 neonates (187 male and 42 female) had a median age at TEPT of 17 days (range 6-28 days). Sixty-eight patients (29.7%) underwent TEPT combined with an abdominal approach or laparoscopy. Early postoperative complications (using the Clavien-Dindo grading system) were documented in 36 patients (15.7%), and late postoperative complications were noted in 9 patients (3.9%). The follow-up period in the remaining 165 children ranged from 1.2 to 14.0 years (median 5.0 years). A total of 106 of the patients older than four years old took part in an interview about bowel function, and 85 patients (80.2%) had bowel function scores (BFS) ≥ 18. CONCLUSION: TEPT is effective and safe for HD in the neonatal period and presents with a low rate of complications and an acceptable outcome.

Comprehensive Analysis of Gut Microbiota and Fecal Bile Acid Profiles in Children With Biliary Atresia.

Background: Biliary atresia (BA) is the most common cholestatic liver disease in neonates. Herein, we aimed at characterizing the gut microbiota and fecal bile acid profiles of BA patients, defining the correlations between them, and evaluating the relationship between the clinical pathogenesis and changes in the gut microbiota and bile acid profiles. Methods: A total of 84 fecal samples from BA patients (n = 46) and matched healthy controls (HCs, n = 38) were subjected to sequencing by 16S rRNA gene amplification, and fecal bile acid were analyzed by targeted metabolomics. Findings: Compared with the controls, a structural separation of the intestinal flora of BA patients was uncovered, which was accompanied by changes in the composition of fecal bile acids. In the BA group, Actinobacillus, Monoglobus, and Agathobacter were enriched in patients without cholangitis (p < 0.05). Selenomonadaceae and Megamonas were more abundant in patients without recurrent cholangitis episodes (p < 0.05), while Lachnospiraceae and Ruminococcaceae were enriched in patients with multiple recurrences of cholangitis (p < 0.05). Postoperative jaundice clearance was associated with Campylobacter and Rikenellaceae (p < 0.05), and tauroursodeoxycholic acid was associated with jaundice clearance (p < 0.001). Conclusion: BA patients are characterized by different compositions of gut microbiota and bile acids, and their interaction is involved in the process of liver damage in BA, which may be closely related to the occurrence of postoperative cholangitis and jaundice clearance.

Risk factors of enterostomy in neonates with Hirschsprung disease.

PURPOSE: This study was aiming to explore the risk factors contributing to enterostomy in neonates with Hirschsprung disease (HD) to provide a reference for clinicians to make treatment decisions. METHODS: Medical records of 284 patients diagnosed with HD during the neonatal period were retrospectively analyzed. The patients were divided into 2 groups based on operative intervention (one stage transanal pull-through, versus enterotomy and staged transanal pull-through). Univariate and multivariable logistic regression analysis was performed to identify risk factors contributing to enterostomy. RESULTS: The incidence of enterostomy was 12.0% (34/284) in neonates with HD. Univariate and multivariate logistic regression analysis showed that serum albumin < 25.4 g/L, radiographic results as subphrenic free air, and level of aganglionosis with long-segment or total colonic aganglionosis (TCA) were independent risk factors of enterostomy in neonates, with OR of 42.045 (6.131, 288.319), 285.558 (26.651, 3059.694) and 15.573 (4.319, 56.157), respectively. CONCLUSIONS: The low serum albumin level, bowel perforation, and level of aganglionosis with long-segment or TCA could influence the occurrence of enterostomy in neonates with HD.
