Multiple gastrointestinal magnetic foreign bodies in children

Objective: To introduce the analysis of the clinical picture, treatment strategy and complications among children having multiple foreign magnetic bodies (FB).Methods: Retrospective analysis of the treatment of 796 children from 2013 to September 2021 having stomach and intestine FB. Comprehensive study included plan radiography of the abdomen, fiberoptic gastroduodenoscopy, etc.Results: Magnets were detected in 33 (4.15%) out of 796 cases. 9 patients swallowed multiple foreign magnetic bodies (FB) within time interval. The parts fixed in different parts of gastrointestinal tract (GIT) and required surgical removal. All patients had multiple perforations of different GIT parts. It required suturing gut wall, bowel resection applying gastrointestinal anasto mosis and celiogrhaphy, resection applying anastomosis and by leaving the programmed laparostomy. Every patient recovered. Algorithm of supervision of children having FB GIT.Conclusions: Multiple foreign magnetic bodies of GIT among children in the current moment are the most dangerous foreign objects accompanied with big amount of complications. They are observed among children of any age and gender and require complicated and long surgical interventions. Multiple foreign magnetic bodies of GIT can be suspected in case of severe surgical pathology along with the lack of passage of radiopaque FB in GIT. Urgent surgical intervention is required in case of detecting it.

A promising new predictive factor for detecting bowel resection in childhood intussusception: the lymphocyte-C-reactive protein ratio

Background The most critical concern for the management of childhood intussusception is bowel resection due to intestinal ischemia and necrosis. The early prediction of this problem is of great importance. We investigated the value of various combinations of inflammatory factors to predict intestinal necrosis and resection. Methods We retrospectively reviewed the medical records of pediatric patients with intussusception who underwent surgical management. During the research period, 47 patients who underwent intestinal resection due to intestinal necrosis and 68 patients who did not undergo intestinal resection were enrolled. We evaluated the diagnostic value of various combinations of inflammatory markers from preoperative laboratory analyses using the receiver operating characteristic (ROC) method. Results In the current cohort, 115 patients underwent operations for intussusception; among them, 47 patients (40.9%) underwent intestinal resections. In the patients with intestinal resection, the neutrophil count(p = 0.013), CRP level(p = 0.002), platelet–lymphocyte ratio (PLR, p = 0.008), NLR (neutrophil–lymphocyte ratio, p = 0.026), and LCR (lymphocyte–CRP ratio, p < 0.001) values were significantly higher than those in the patients without any resection. The receiver operating characteristic (ROC) analysis results showed that the combination of lymphocytic count along with C-reactive protein levels (LCR) demonstrated the highest correlation with intestinal resection due to intussusception compared with other parameters in the patients, with a sensitivity of 0.82 (0.73–0.86) and specificity of 0.80 (0.57–0.94) for the diagnosis of strangulation. Conclusion The preoperative LCR level is a useful marker to predict the need for intestinal resection due to intestinal necrosis in patients with intussusception.

Lipid absorption and overall intestinal lymphatic transport are impaired following partial small bowel resection in mice

Short bowel syndrome (SBS) is associated with diminished levels of serum fats caused by unknown mechanisms. We have shown that mesenteric lymphatics remodel to a more primitive state one week after small bowel resection (SBR); therefore, this study focuses on the effect of chronic lymphatic remodeling and magnitude of resection on intestinal fatty acid uptake and transport. C57BL6 and Prox1 creER-Rosa26LSLTdTomato (lymphatic reporter) mice underwent 50% or 75% proximal SBR or sham operations. Functional transport of lipids and fecal fat content was measured and lymphatic vasculature was compared via imaging. There was a significant reduction in functional transport of cholesterol and triglyceride after SBR with increasing loss of bowel, mirrored by a progressive increase in fecal fat content. We also describe significant morphological changes in the lymphatic vasculature in both the lamina propria and mesentery. Intestinal lymphatic drainage assay in vivo demonstrated a marked reduction of systemic absorption after resection. Intestinal lymphatic vessels significantly remodel in the setting of chronic SBS. This remodeling results in impaired intestinal transport of fat via the compromised lymphatic architecture, contributing to decreased fatty acid uptake. We believe that these changes may contribute to the development of IFALD, a major morbidity in patients with SBS.
