The management of colonic polyps in children: a 13-year retrospective study. Eur J Pediatr 2021; 180:2281-2286. [PMID: 33728535 DOI: 10.1007/s00431-021-04017-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 02/09/2021] [Accepted: 03/04/2021] [Indexed: 10/21/2022]
Abstract
The aim of this study was to describe the frequency, major symptoms, and characteristics of colonic polyps in a cohort of children. A retrospective chart review of patients aged ≤ 18 years who were diagnosed with colonic polyp(s) from 2006 to 2019 in a tertiary hospital was included. Data collected included demographics, clinical presentation, interval of time between the onset of symptoms and the endoscopic diagnosis of colonic polyps, family history, characteristics of the polyp, and associated lesions. Over the study period, 35 Caucasian children were diagnosed with juvenile colonic polyps. Twenty-three patients (65.7%) were males. Lower gastrointestinal bleeding of a mean duration of 5.3 ± 4.9 months was the presenting symptom in nearly all cases (n = 34, 97%), and it was isolated in 17 patients. Clinical presentation did not significantly vary according to the age or the location or size of the polyp (p = 0.262, p = 1.000, and p = 0.149, respectively). The polyps were mainly located in the left colon (n = 29, 83%). Right colonic polyps were significantly larger than left colonic polyps (p = 0.037).Conclusion: Lower gastrointestinal bleeding represents the most common presentation of colonic polyps in children. Right-sided colonic polyps occur and may be even larger than left-sided ones. A total colonoscopy is therefore mandatory for all cases of suspected colonic polyps. This study represents a real-life contribution, and it can help improve the management strategies of this condition in childhood. What is Known: • Colonic polyps are quite common in children. • The majority of pediatric colonic polyps are solitary, benign, and located in the left colon. What is New: • Right-sided colonic polyps occur and may be even larger than left-sided ones. • A total colonoscopy is mandatory for all cases of suspected colonic polyps.

Abstract
BACKGROUND/AIMS Colorectal polyps are a common cause of lower gastrointestinal bleeding in children. Our aim was to study the causes of isolated lower gastrointestinal bleeding and to analyze the characteristics of the colorectal polyps found in our cohort. METHODS We retrospectively reviewed colonoscopic procedures performed between 2007 and 2015. Children with isolated lower gastrointestinal bleeding were included in the study. RESULTS A total of 185 colonoscopies were performed for isolated lower gastrointestinal bleeding. The median patient age was 8 years, and 77 patients (41.6%) were found to have colonic polyps. Normal colonoscopy findings were observed and acute colitis was detected in 77 (41.6%) and 14 (7.4%) patients, respectively. Single colonic polyps and 2-3 polyps were detected in 73 (94.8%) and 4 (5.2%) patients with polyps, respectively. Of the single polyps, 69 (94.5%) were juvenile polyps, among which 65 (94.2%) were located in the left colon. CONCLUSION Single left-sided juvenile polyps were the most common cause of isolated lower gastrointestinal bleeding in our study. It was rare to find multiple polyps and polyps proximal to the splenic flexure in our cohort. A full colonoscopy is still recommended in all patients in order to properly diagnose the small but significant group of patients with pathologies found proximal to the splenic flexure.

PLoS One 2018; 13:e0209333. [PMID: 30562400 PMCID: PMC6298661 DOI: 10.1371/journal.pone.0209333] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Accepted: 12/04/2018] [Indexed: 11/18/2022] Open
Abstract
Background Infection with Schistosoma mansoni is a major cause of morbidity and mortality in endemic areas, and is increasingly diagnosed in migrants and travellers outside transmission areas. Markers for the assessment of morbidity and impact of control programs in endemic areas and for the clinical management of patients in the clinical setting are scant, especially for intestinal involvement. Ultrasonography is well established to evaluate hepatosplenic pathology; on the contrary, ultrasound evaluation of intestinal schistosomiasis is virtually unexplored. In this pilot study, we aimed to describe and evaluate the accuracy of unenhanced intestinal ultrasound for morbidity due to intestinal S. mansoni infection. Methodology/Principal findings We performed a blind case-control study of unenhanced intestinal ultrasound on 107 adults accessing the outpatient clinic of our Centre for Tropical Diseases between January-July 2018 as part of a screening for tropical diseases in migrants and travellers returning from endemic areas. Other clinical and laboratory data were obtained routine examination reports. We could not find any overtly pathological thickness of the gut wall in the sigma, proximal ascending colon, and terminal ileum, in patients with S. mansoni infection (n = 17), S. haematobium infection (n = 7), positive anti-Schistosoma serology (n = 31), and uninfected individuals (n = 52), with no difference among groups as assessed by ANOVA. No polyps or other intestinal abnormalities were visualized. There was no significant change in gut wall thickness one month after treatment with praziquantel in patients with S. mansoni infection (n = 11). Conclusions/Significance Our preliminary results suggest that intestinal ultrasound might not be a sensitive tool for detecting minor intestinal morbidity due to schistosomiasis. Further studies in a hospital setting comparing colonoscopy and ultrasonography may be envisaged; in endemic areas, further studies are needed to describe and assess the usefulness of intestinal ultrasound in patients stratified by infection intensity and compared with markers such as calprotectin and fecal occult blood.

Abstract
BACKGROUND/AIM Endoscopic mucosal resection (EMR) is widely used for treating gastrointestinal polypoid lesions. However, it is currently unclear whether antibiotic administration is necessary after EMR of colon polyps to prevent infection. We aimed to assess whether antibiotic administration is essential in such conditions. MATERIALS AND METHODS In total, 115 patients with colon polyps were randomly assigned to 3 groups based on the treatment given after EMR: Group A, no antibiotics treatment after EMR (n = 38); Group B, administration of levofloxacin after EMR (n = 38); and Group C, administration of ceftazidime after EMR (n = 39). RESULTS The colon polyps were completely removed by EMR in all cases without any serious complications. Although infection developed in 2 cases in Group A, it was resolved via levofloxacin injection over 3 days; infection did not develop in any cases in Group B and C. The postoperative infection rate was not significantly different among Groups A, B, and C. After 6 months, we noted that the wound surface had properly healed and there was no relapse of colon polyps in any patients. CONCLUSION The use of antibiotics after EMR of colon polyps to prevent infection did not affect the prognosis of patients.

Abstract
A polyp is defined as a mass of the mucosal surface that protrudes into the lumen of the gastrointestinal tract. Neoplastic epithelial polyps are classified histologically as either benign adenoma or malignant carcinoma. The colonic polyps that most commonly present in children occur sporadically and individually and are of the juvenile type; they are most frequently associated with painless rectal hemorrhage (which is the most common symptom). Adenomatous polyps are similar to other nontumoral polyps, and it is very rare for children to have symptoms other than rectal bleeding. This report describes two rare cases of polyps in pediatric patients. An 11-year-old girl presented with tubulovillous adenoma and a 13-year-old boy with tubular adenoma; both patients complained of rectal hemorrhage as well as anemia and abdominal pain. Epithelial adenoma is a tumor that is rarely found in adults or children. Colonoscopic perforation and biopsy are mandatory for establishing a definitive diagnosis and avoiding medical mismanagement.

Fecal occult blood and fecal calprotectin as point-of-care markers of intestinal morbidity in Ugandan children with Schistosoma mansoni infection. PLoS Negl Trop Dis 2013; 7:e2542.

Abstract
Background Calprotectin is a calcium-binding cytoplasmic protein found in neutrophils and increasingly used as a marker of bowel inflammation. Fecal occult blood (FOB) is also a dependable indicator of bowel morbidity. The objective of our study was to determine the applicability of these tests as surrogate markers of Schistosoma mansoni intestinal morbidity before and after treatment with praziquantel (PZQ). Methods 216 children (ages 3–9 years old) from Buliisa District in Lake Albert, Uganda were examined and treated with PZQ at baseline in October 2012 with 211 of them re-examined 24 days later for S. mansoni and other soil transmitted helminths (STH). POC calprotectin and FOB assays were performed at both time points on a subset of children. Associations between the test results and infection were analysed by logistic regression. Results Fecal calprotectin concentrations of 150–300 µg/g were associated with S. mansoni egg patent infection both at baseline and follow up (OR: 12.5 P = 0.05; OR: 6.8 P = 0.02). FOB had a very strong association with baseline anemia (OR: 9.2 P = 0.03) and medium and high egg intensity schistosomiasis at follow up (OR: 6.6 P = 0.03; OR: 51.3 P = 0.003). Both tests were strongly associated with heavy intensity S. mansoni infections. There was a significant decrease in FOB and calprotectin test positivity after PZQ treatment in those children who had egg patent schistosomiasis at baseline. Conclusions Both FOB and calprotectin rapid assays were found to correlate positively and strongly with egg patent S. mansoni infection with a positive ameloriation response after PZQ treatment indicative of short term reversion of morbidity. Both tests were appropriate for use in the field with excellent operational performance and reliability. Due to its lower-cost which makes its scale-up of use affordable, FOB could be immediately adopted as a monitoring tool for PC campaigns for efficacy evaluation before and after treatment. The severity of intestinal schistosomiasis, a disease caused by Schistosoma mansoni infection, is likely under-reported in part due to the scarcity of field-appropriate morbidity markers. Downstream potential complications of this disease include anemia, failure to thrive, and chronic multi-organ damage. Point-of-care (POC) tools to monitor intestinal schistosomiasis in low resource settings are urgently needed to better quantify the burden of disease in endemic countries and to gauge the clinical impact of scale-up of preventive PC. For the present study in rural Uganda, fecal occult blood and fecal calprotectin were identified as potential surrogate markers of intestinal morbidity. We tested both POC tests and found that they were both associated with active schistosomiasis as detected by eggs in stool with significant decrease in test positivity after PZQ treatment demonstrating short term morbidity reversion. Calprotectin was a strong indicator of intestinal inflammation, however, owing to its high per-test price makes it difficult to scale-up accordingly. Conversely, fecal occult blood was technically feasible, low-cost and had optimal performance as a morbidity marker, hence we strongly advocate for its immediate inclusion as a monitoring tool for PC programs.

Abstract
AIM: To detect the expression of E-cadherin and β-catenin mRNAs and proteins in human colorectal juvenile polyps (JP) in children.
METHODS: The expression of E-cadherin and β-catenin mRNAs and proteins in 22 juvenile colorectal polyp specimens and 8 normal colorectal specimens was assayed by real-time PCR and Western blot, respectively. Immunohistochemistry was used to determine the expression and localization of E-cadherin and β-catenin in 30 juvenile colorectal polyp specimens and 10 normal colorectal specimens.
RESULTS: Real-time PCR and Western blot analyses showed that the expression levels of E-cadherin mRNA and protein were significantly lower in juvenile colorectal polyps than in normal colorectal specimens (1.1526 ± 0.3801 vs 0.4094 ± 0.2305, P < 0.05; 0.6028 ± 0.1778 vs 0.3257 ± 0.1168, P < 0.05). Although there was no significant difference in the expression level of β-catenin mRNA between the two groups, the expression of β-catenin was significantly higher in juvenile colorectal polyps than in normal colorectal specimens (0.8010 ± 0.1380 vs 1.2064 ± 0.3587, P < 0.05). Immunohistochemistry indicates that E-cadherin expression was down-regulated in juvenile polyps compared with controls (102.5155 ± 25.2988 vs 53.5772 ± 15.3205, P < 0.05). Positive staining for E-cadherin was predominantly localized on the epithelial cell membrane. The expression of β-catenin was increased in juvenile polyp specimens (112.0805 ± 24 9572 vs 260.3554 ± 86.6987, P < 0.05), and the positive rates of membrane, cytoplasmic and nuclear staining in juvenile polyp tissue was significantly higher than those in normal control tissues.
CONCLUSION: Dysregulation of E-cadherin and β-catenin expression may be an important feature of juvenile colorectal polyps.

Abstract
There is a need for field-applicable markers to assess morbidity associated with intestinal schistosomiasis, especially in the context of preventive chemotherapy in young children. We investigated whether fecal occult blood (FOB) point-of-care tests could be used to assess intestinal pathology over a 12-month period in a cohort of 382 children (< 5 years of age). We found a strong association between egg-patent schistosomiasis and FOB at baseline (odds ratio [OR] = 3.1, P < 0.0001), 6 months (OR = 3.4, P < 0.0001), and 12 months (OR = 3.5, P < 0.0001), despite repeated chemotherapy. There were tendencies for prevalence of FOB to decrease in children who became egg negative and increase in those who became egg positive. Our results demonstrate overt disease in children less than five years of age. We therefore propose that FOB is useful for assessing dynamics of intestinal morbidity in young children at the community level and monitoring changes in morbidity after mass chemotherapy.
