Meckel's Diverticulum in Children: A Monocentric Experience and Mini-Review of Literature.

Vitelline duct anomalies (VDA, including Meckel's diverticulum (MD)) result from failed embryologic obliteration. This study aimed for characteristics in symptomatic versus asymptomatic VDA, analyzing clinico-laboratory data from 73 children, aged 1 day to 17 years, treated at a tertiary Pediatric Surgery Institution from 2002-2017. A male preponderance was obtained (ratio 3.6:1). MD accounted for 85% of VDA. Incidence of symptomatic VDA decreased with older age. Leading symptoms were intestinal obstruction and hemorrhage. Mucosal heterotopia (present in 39% of symptomatic MD) was associated with anemia and lowered CRP-levels. On ROC-analysis, hemoglobin < 8.6 g/dL, CRP < 0.6 mg/dL and MD distance to ileocecal valve >40 cm were predictors of ectopic tissue in symptomatic MD. Our data confirmed known characteristics as male preponderance, declined incidence of symptomatic cases with age and predominance of gastric ectopia in symptomatic MD. Moreover, anemia and prolonged distance of MD to ileocecal valve were predictors of ectopic mucosa in symptomatic MD.

Pediatric Urachal Anomalies: Monocentric Experience and Mini-Review of Literature.

BACKGROUND: Surgery is the current mainstay for the treatment of urachal anomalies (UA). Recent literature data support the theory of a spontaneous resolution within the first year of life. The aim of this study, comprising solely surgically treated children, was to identify age specific patterns regarding symptoms and outcomes that may support the non-surgical treatment of UA. METHODS: Retrospective review on the clinico-laboratory characteristics of 52 children aged < 17 years undergoing resection of symptomatic UA at our pediatric surgical unit during 2006-2017. Data was dichotomized into age > 1 (n = 17) versus < 1 year (n = 35), and complicated (pre-/post-surgical abscess formation or peritonitis, n = 10) versus non-complicated course (n = 42). RESULTS: Children aged < 1 year comprised majority (67%) of cohort and had lower complication rates (p = 0.062). Complicated course at surgery exclusively occurred in patients aged > 1 year (p = 0.003). Additionally, complicated group was older (p = 0.018), displayed leukocytosis (p < 0.001) and higher frequencies regarding presence of abdominal pain (p = 0.008) and abdominal mass (p = 0.034) on admission. Regression analysis identified present abdominal pain (OR (95% CI), 11.121 (1.152-107.337); p = 0.037) and leukocytosis (1.435 (1.070-1.925); p = 0.016) being associated with complicated course. CONCLUSIONS: This study provides evidence that symptomatic disease course follows an age-dependent complication pattern with lower complication rates at age < 1 year. Larger, studies have to clarify, if waiting for spontaneous urachal obliteration during the first year of life comprises a reasonable alternative to surgery.

Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio Might Predict Pediatric Ovarian Torsion: A Single-Institution Experience and Review of the Literature.

STUDY OBJECTIVE: To determine clinical and laboratory characteristics of ovarian torsion (OT; n = 28) compared with a non-OT control (OC; n = 64) group. DESIGN: Retrospective single-center review performed between January 2006 and December 2016. SETTING: Academic department of pediatric surgery. PARTICIPANTS AND INTERVENTIONS: Postoperative diagnosis of pediatric ovarian pathology (International Classification of Diseases, 10th Revision code N83) in 88 patients who underwent 92 surgeries for suspected OT, aged from 3 days to 17.8 years. MAIN OUTCOME MEASURES: Predictive value for OT according to biometric, procedural, and laboratory parameters at the time of admission. RESULTS: Compared with OC, OT in patients aged older than 1 year was associated with elevated values regarding white blood cell count, neutrophils, neutrophil to lymphocyte ratio (NLR; all P < .001), platelet to lymphocyte ratio (PLR; P = .003), platelets (P = .011), and a trend toward raised C-reactive protein (P = .054), whereas lymphocytes and lymphocyte to C-reactive protein ratio (both P < .001) were decreased. Using receiver operating characteristic analysis for differentiating OC from OT, besides lymphocytes and NLR (both area under the curve > 0.9), PLR elicited strongest discriminatory accuracy (area under the curve = 0.946 ± 0.037; P < .001; sensitivity 82%; specificity 90%). At binary logistic regression analysis PLR (P = .018) was independently predictive of OT. OT was suspected on ultrasound imaging in 15/18 (83%), showed a right-sided dominance in 13/18 (72%), and was associated with younger age (P = .003). No differences regarding laboratory or procedural parameters in patients aged younger than 1 year were discerned. CONCLUSION: Blood count indices such as PLR, NLR, and lymphocyte to C-reactive protein ratio might be helpful in identification of inflammatory processes as induced by ischemia in OT. Together with ultrasound and clinical features, these parameters constitute potential predictors of OT in girls aged older than 1 year.

Posthemorrhagic hydrocephalus in extremely low birth weight infants: Ommaya reservoir vs. ventriculoperitoneal shunt.

PURPOSE: The aim of this study was to analyze morbidity and initial surgery in infants with posthemorrhagic hydrocephalus (PHH) by comparing infants who were treated with a subcutaneous cerebrospinal fluid reservoir (Ommaya reservoir = CSF_R) with infants who primarily received a ventriculoperitoneal shunt (VPS). METHOD: Inclusion criteria were infants born between January 2006 and June 2014 who had a diagnosis of intraventricular hemorrhage (IVH) and underwent surgical intervention for hydrocephalus. RESULTS: Twenty-five infants, with a median gestational age (GA) of 26.5 (28 ± 4) weeks and a median birth weight (BW) of 980 g (1205 ± 837), were included. The median umbilical artery pH (UApH) was 7.30 (7.20 ± 0.25). The median Apgar score at 10 min was 8 (7.4 ± 2). Twenty-five peri- and postnatal adverse events were encountered preoperatively. The IVH grades were grade II (n = 1), grade III (n = 17), grade IV (n = 6), and unknown grade (n = 1). Primary treatment consisted of CSF_R (n = 18) or VPS (n = 7) placement. There was a statistically significant difference between the postnatal ages of infants with CSF_R (32.5 days; 42 ± 28) and infants with VPS (163 days; 161 ± 18). Furthermore, we found a difference regarding GA but not BW between both groups. Arrest of PHH with shunt independence occurred in two infants from the CSF_R group (11%). CONCLUSIONS: In the present study, early insertion of CSF_R allowed stabilization of the infants and thus postponement of permanent VPS insertion. However, in a subgroup of patients, PHH develops over a more prolonged course, and VPS insertion can be performed initially without the need for CSF_R.
