Background and Objecitves: Appendicitis is one of the most frequent surgical emergencies in pediatric surgery. Complicated appendicitis can evolve with appendicular peritonitis characterized by the diffusion of the pathological process to the peritoneal cavity, thus producing generalized or localized inflammation of the peritoneum. The capacity to anticipate the possibility of perforation in acute appendicitis can direct prompt management and lower morbidity. There is no specific symptom that could be used to anticipate complicated appendicitis, and diagnostic clues include a longer period of symptoms, diffuse peritoneal signs, high fever, elevated leukocytosis and CRP, hyponatremia, and high ESR. Imagistic methods, particularly US and CT, are useful but not sufficient. There are no traditional inflammation biomarkers able to predict the evolution of uncomplicated to complicated appendicitis alone, but the predictive capacity of novel biomarkers is being investigated. Materials and Methods: The present study represents a retrospective evaluation of children hospitalized between January 2021 and July 2022 in the Grigore Alexandrescu Clinical Emergency Hospital for Children with a diagnosis of acute appendicitis settled based on clinical characteristics, traditional and novel biomarkers, and ultrasonographic features. The children were subsequently grouped into two groups based on the existence of appendicular peritonitis on intraoperative inspection of the abdominal cavity. The aim of this report is to establish the predictors that may aid physicians in timely identifying pediatric patients diagnosed with acute appendicitis at risk for developing complicated appendicitis with evolution to appendicular peritonitis. Results: The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte radio (PLR) are representative severity markers in infections. This report analyzes the benefit of these markers for distinguishing uncomplicated appendicitis from complicated appendicitis in pediatric patients. Conclusions: Our study suggests that a value of neutrophil-to-lymphocyte ratio greater than 8.39 is a reliable parameter to predict the evolution to appendicular peritonitis.

Background: Neuroblastoma (NB) is the most common pediatric extracranial solid tumor and the most common cancer encountered in children younger than 12 months of age. Localized tumors have a good prognosis, but some cases undergo treatment failure and recurrence. The aim of the study was to analyze the link between the neuroblastoma risk factors and the prognosis for patients diagnosed with NB. Method: All patients admitted to the department of Pediatric Surgery, “Grigore Alexandrescu” Clinical Emergency Hospital for Children, between 1 January 2010 and 1 July 2022 were included in this analysis when diagnosed with neuroblastoma. Results: Thirty-one patients with NB were admitted to the surgical department, 20 boys and 11 girls. We observed an association between large tumors and positive imaging-defined risk factor (IDRF) status; The Fisher test showed an association between the tumor’s diameter when bigger than 8 cm and a positive IDRF status, with p < 0.001. We supposed that positive IDRF status at diagnosis may be linked to other prognostic factors. We discovered that an NSE value over 300 was associated with IDRF status (p < 0.001, phi = 0.692) and death. Conclusions: This study confirms the impact of IDRF status at diagnosis as it can be clearly correlated with other risk factors, such as a high level of NSE, MYCN amplification status, large tumor size, incomplete tumor resection, and an unfavorable outcome.

Background and Objectives: Choledocal cyst is a rare congenital disease of the biliary tree defined by dilatation of the extrahepatic and/or intrahepatic biliary ducts. Untreated, it leads to complications such as cholangitis, stone formation and malignant degeneration. The standard treatment for choledocal cyst is complete excision and subsequent biliary reconstruction via hepaticojejunostomy or hepatiocoduodenostomy. Materials and Methods: We report our experience with 16 pediatric cases of choledocal cyst over a 10-year period. Results: The predominant symptoms were nausea and jaundice, both at 62.5% (n = 10), followed by abdominal pain at 56.3% (n = 9). Ultrasonography was the diagnostic method used in all patients. Computed tomography was used in 75% (n = 12) and magnetic resonance imaging in 25% (n = 4) of cases. Age at the time of intervention ranged from 2 months to 17 years with a mean of 4 years and 5 months. The open approach was used in nine patients and the laparoscopic approach was used in seven patients, with one conversion to open surgery. Complete excision of the choledocal cyst was performed in 15 cases (93.7%), and partial excision with mucosectomy was performed in one case (6.2%). Eight patients (50%) underwent hepaticoduodenostomy and eight (50%) underwent hepaticojejunostomy, out of which one was attempted laparoscopically but was converted. We had a postoperative complication rate of 12.5% (n = 2) represented by anastomotic leak and pancreatitis. Conclusions: From our experience with these cases, we concluded that a wide hepaticoduodenostomy constitutes a favorable choice over the traditional hepaticojejunostomy, being more physiological and less time consuming.

Background and Objectives: Duodenal atresia and stenosis are common causes of intestinal obstruction. Associated anomalies significantly influence early postoperative mortality, while postoperative complications impact long-term survival. Materials and Methods: Over a 13-year period from January 2010 to August 2023, a total of 74 infants and children with congenital duodenal obstruction were treated at “Grigore Alexandrescu” Children’s Emergency Hospital and met the inclusion criteria. All patients diagnosed with duodenal obstruction (both instrinsic and extrinsic causes) were included. Analysed data included congenital anomalies, Apgar scores, birth weights, surgical techniques, and complications. Results: The associated anomalies included cardiac (n = 33), Down syndrome (n = 13), neurological (n = 11), pulmonary (n = 7), renal (n = 4), skeletal (n = 1), and gastrointestinal and hepatobiliopancreatic anomalies (n = 25). In total, 12 patients experienced perioperative ventilation problems. Early postoperative complications (within 30 days) occurred in 21 patients, while 6 had late postoperative complications (after 30 days). Among non-surgical complications, we noted ventilation problems, sepsis (n = 7), and pneumothorax (n = 1). Surgical complications included adhesive bowel obstruction (n = 7), incisional hernia (n = 3), peritonitis (n = 3), dysfunctional duodenoduodenostomy or duodenojejunostomy (n = 3), pneumoperitoneum (n = 5), enteric fistula (n = 3), and volvulus (n = 4). Conclusions: Surprisingly, this retrospective study revealed that an Apgar score below 8, along with neurological and pulmonary abnormalities, is associated with postoperative complications. Conversely, other congenital anomalies, low birth weight, and age at admission do not serve as prognostic factors.

Gastrointestinal hemangiomas (GIH) are unusual vascular tumors found anywhere alongside the GI tract, the small bowel being the most common site. Diagnosis requires good clinical insight and modern imaging. This is a comprehensive review of the literature, starting from a new pediatric case diagnosed through exploratory laparotomy after complex imaging techniques failed. This research was conducted on published articles from the past 25 years. We identified seventeen original papers (two series of cases with three and two patients, respectively, and fifteen case reports). The female/male ratio was 1.5. The youngest patient was a 3-week-old boy, and the was oldest a 17-year-old girl. The most common localization was the jejunum (eight cases), followed by the ileum (four), colon (three), stomach (two), and rectum (one). Seven children had cavernous and four had capillary hemangiomas. Eight patients presented gastrointestinal bleeding, seven had refractory anemia, such as our index patient, three had recurrent abdominal pain, and two had bowel obstruction. Surgical assessment was successful in fifteen cases; three cases experienced great outcomes with oral propranolol, one child was treated successfully with sirolimus, and for one patient, endoscopic treatment was the best choice. The authors present the case of a female patient admitted to the Pediatrics Department of “Grigore Alexandrescu” Emergency Children’s Hospital from 25 February to 28 March 2019 for severe anemia, refractory to oral iron treatment, and recurrent blood infusions. No clear bleeding cause had been found. Although very uncommon, intestinal hemangiomas can express puzzling, life-threatening symptoms. We should keep in mind this disorder in cases of unresponsive chronic anemia.

Background and Objectives: To assess the current practice pattern in the management of pediatric acute appendicitis in Romania. Materials and Methods: A questionnaire was emailed to all the members of the Romanian Society of Pediatric Surgery between June–July 2022. Results: 118 answers were received, 79.7% responses being from permanent staff members. In the diagnosis of appendicitis, complete blood count, C-reactive protein and abdominal ultrasound are the most commonly used diagnostic tools, while appendicitis scores are not widely used (25% of surgeons). In the case of simple appendicitis, 49.2% of surgeons prefer the conservative approach—oral/intravenous antibiotics. Those who choose the operative approach begin preoperative antibiotics in 56.7% of patients. In case of a stable patient, only 16.7% of surgeons will operate during the night. Laparoscopic approach is chosen by 51.7% of surgeons. In the case of a complicated appendicitis, 92.4% of surgeons will perform the appendectomy, prescribing preoperative antibiotics in 94% of the cases and continuing the therapy postoperatively in 98.2%. Laparoscopic approach is used by 28.8% of surgeons in case of complicated appendicitis. In presence of appendicular mass, 80% prefer a conservative approach with a delayed appendectomy within 6 months. Appendicular abscesses are managed operatively in 82.2% of the cases. The appendix is sent for histological analysis by 95.8% of surgeons. If the peritoneal cavity is contaminated, 95% of the respondents will take a sample for microbiological analysis, 71% will always place a drainage and 44% will always irrigate (71.9%-saline). Conclusions: Clearly, there seems to be a lack of consensus regarding several aspects of the management of acute appendicitis in children. In addition, minimally invasive surgery is not as widely used as reported, despite literature support.
