Approximately 40% of children with Hirschsprung’s disease (HD) suffer from Hirschsprung’s associated enterocolitis (HAEC) despite correct surgery. Disturbances of the intestinal microbiome may play a role. Treatment with probiotics based on individual analyses of the fecal microbiome has not been published for HD patients with recurrent HAEC yet. A boy with trisomy 21 received transanal pull-through at the age of 6 months for rectosigmoid HD. With four years, he suffered from recurrent episodes of HAEC. The fecal microbiome was measured during three healthy and three HAEC episodes by next-generation sequencing. The patient was started on daily probiotics for 3 months; the fecal microbiome was measured weekly. The fecal microbiome differed significantly between healthy and HAEC episodes. HAEC episodes were associated with significant decreases of Actinobacteria and significant increases of Bacteroidetes and Proteobacteria. Probiotic treatment led to a significant increase of alpha diversity and a significant increase of Bifidobacterium and Streptococcus as well as decreases of Rikenellaceae, Pseudobutyrivibrio, Blautia, and Lachnospiraceae. A longitudinal observation of the microbiome has never been performed following correction of Hirschsprung’s disease. Probiotic treatment significantly changed the fecal microbiome; the alterations were not limited to strains contained in the administered probiotics.

AbstractRobotic surgery offers three-dimensional visualization and precision of movement that could be of great value to gastrointestinal surgeons. There were many previous reports on robotic technology in performing Soave colonic resection and pull-through for Hirschsprung’s disease in children. This study described the follow-up of the Robotic-assisted Soave procedure for Hirschsprung’s disease in children. Robotic-assisted endorectal pull-through was performed using three robotic arms and an additional 5-mm trocar. The ganglionic and aganglionic segments were initially identified by seromuscular biopsies. The rest of the procedure was carried out according to the Soave procedure. We left a short rectal seromuscular sleeve of 1.5–2 cm above the dentate line. From December 2014 to December 2017, 55 pediatric patients were operated on. Age ranged from 6 months to 10 years old (median = 24.5 months). The aganglionic segment was located in the rectum (n = 38), the sigmoid colon (n = 13), and the left colon (n = 4). The mean total operative time was 93.2 ± 35 min (ranging from 80 to 180 min). Minimal blood was lost during the surgery. During the follow-up period, 41 patients (74.6%) had 1–2 defecations per day, 12 patients (21.8%) had 3–4 defecations per day, and 2 patients (3.6%) had more than 4 defecations per day. Fecal incontinence, enterocolitis, and mild soiling occurred in three (5.4%), four (7.3%), and two pediatric patients, respectively. Robotic-assisted Soave procedure for Hirschsprung’s disease in children is a safe and effective technique. However, a skilled robotic surgical team and procedural modifications are needed.

The clothes moth Tineola bisselliella is one of a few insects that can digest keratin, leading to the destruction of clothing, textiles and artwork. The mechanism of keratin digestion is not yet fully understood, partly reflecting the lack of publicly available genomic and transcriptomic data. Here we present a high-quality gut transcriptome of T. bisselliella generated from larvae reared on keratin-rich and keratin-free diets. The overall transcriptome consists of 428,221 contigs that were functionally annotated and screened for candidate enzymes involved in keratin utilization. As a mechanism for keratin digestion, we identified cysteine synthases, cystathionine β-synthases and cystathionine γ-lyases. These enzymes release hydrogen sulfite, which may reduce the disulfide bonds in keratin. The dataset also included 27 differentially expressed contigs with trypsin domains, among which 20 were associated with keratin feeding. Finally, we identified seven collagenases that were upregulated on the keratin-rich diet. In addition to this enzymatic repertoire potentially involved in breaking down keratin, our analysis of poly(A)-enriched and poly(A)-depleted transcripts suggested that T. bisselliella larvae possess an unstable intestinal microbiome that may nevertheless contribute to keratin digestion.

Introduction Patients after pull-through operation for Hirschsprung's disease (HD) are at high risk of defecation disorders. This study aimed at investigating their long-term outcomes and quality of life (QoL) in comparison with controls. Patients and Methods Patients older than 5 years operated on for HD were interviewed to complete detailed questionnaires on bowel function. Patients without neurologic impairment were enrolled in a QoL survey to compare with controls matched for sex and age and selected randomly from the general population using sampling set in a ratio of four controls to one case of HD. Results In total, 53 operated patients were enrolled. Mean age of the patients was 16 ± 8 years, with 68% boys. Rectosigmoid aganglionosis was the most seen form of HD in 38 (72%) cases. Open Soave was performed in 40 (75.5%) cases, and minimally invasive surgery Soave (MIS Soave) in 13 (24.5%) cases. At investigation, prevalence of fecal incontinence and constipation were 22.6 and 13.2%, respectively. Regarding QoL survey, 45 patients and 180 controls were enrolled, excluding 8 patients with neurologic impairment. Thirty-seven (82.2%) patients were classified as having a good QoL (score ≥ 9 points); whereas six had a fair QoL (5–8 points) and two had a poor QoL (< 5 points). QoL score in the cases and the controls were 10.2 ± 2.5 and 11.9 ± 0.4 points, respectively. Long aganglionosis form of HD was significantly associated with a low QoL (score < 8 points), adjusted odds ratio = 9, 95% confidence interval [1.3; 64.1] (p < 0.05). In subscales analyses, the prevalence of each dimension including fecal continence, school absenteeism, unhappiness or anxiety, food restriction, and peer rejection was significantly higher in operated patients than in controls (p <0.001). Conclusion Although the QoL of patients operated on for HD in general was with good outcomes, fecal incontinence and constipation still are problematic issues and challenges in a high percentage of patients. Therefore, a long-term and multidisciplinary follow-up is essentially required for these patients.
