Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung's disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung's disease) from 264 hospitals (89 in high-income countries, 166 in middle-income countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in low-income countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between low-income, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030.

Introduction: The incidence of N1 and N2 metastases in relation to the presence of peritumoral lymphovascular infiltration and tumor grade in bronchial carcinoma still remain insufficiently researched areas that could provide valuable guidance. Several studies have shown a statistically significant difference in the occurrence of N1 and N2 metastases in relation to the type and size of the bronchial carcinoma. The relationship between the occurrence of N1 and N2 metastases and the degree of immaturity of the tumor in the bronchial carcinoma remains insufficiently documented. Patients and methods: This study included 331 patients of all ages, both men and women, diagnosed with bronchial carcinoma using various diagnostic procedures. In these patients, surgical treatment was indicated and the anatomical resection was performed. Result: A total of 331 patients were included in the study and N1 metastases were present in 39.88% of cases, while N2 metastases were present in 4.53% of cases with bronchial carcinoma. Peritumoral lymphovascular invasion was present in 37.55% of cases (86 out of 229 patients) with N0 disease, in 55.89% of cases (128 out of 229 patients) with N1 disease, and in 6.55% of cases (15 out of 229 patients) with confirmed N2 disease. Conclusion: The presence of the peritumoral lymphovascular invasion is more often accompanied by metastases in corresponding regional lymph nodes. By calculating the total relative risk, there is almost a 30-fold higher risk of developing metastases in N1 and N2 lymph nodes in the presence of peritumoral lymphovascular invasion.

A 10 years old boy, was sent from regional hospital. His symptoms started the day before he was hospitalized and represented as gastrointestinal bleeding, lower abdominal pain and four times vomiting, without fever. Ultrasound and X-ray of the abdomen were normal. Blood fi ndings showed: RBC 3,19, hemoglobin 0,95, hematocrit 0,27. During a physical examination abdomen was palpatory soft, with no presence of the pain. Digital rectal examination showed blood. A scintigraphy pathologic scan showed a focal lesion of the right hemi abdomen consistent with the Meckel’s diverticulum.Patient was treated byLaparoscopic-Assisted Transumbilical Extracorporeal Resection of the Meckel’s Diverticulum. Case Report

Background: Kidney is the most common site of genitourinary trauma. 50% of all urinary injuries is kidney.Kidney is also affected in 8-12% of all blunt and penetrating trauma to abdomen. 80-90% of renal injury is caused by blunt injury GY. Children,  compared to adults, have  at a higher risk of renal injury from blunt trauma due to a variety of anatomic factors including decreased perirenal fat, weaker abdominal muscles, and a less ossified thoracic cage. While there are strong trends toward non-operative management of blunt renal trauma, there are no explicit guidelines for high grade injuries. Organ preservation in children is always a primary goal with solid organ injury. Aim of the work: The aim of the retrospective study is to show the specificity of kidney injury in children as well as the specificity of surgical treatment. Material and Methods: All 19 patients under the age of 18 who were admitted to Clinic for Pediatic surgery in Sarajevo with a diagnosis of renal trauma were retrospectively reviewed .The Echo an CT were used to identify patients with a renal injury. The time period examined was between January 1, 1999- 2019. Inclusion criteria were either a diagnosis of renal trauma or a diagnosis of blunt abdominal trauma and hematuria. Exclusion criterion was death due to an additional traumatic injury. The mechanism of injury (fall, car accident , assault) injury grade (I-V), the presence of hematuria, and demographic data to include age, weight, and sex, were recorded and reviewed.  In addition, amount of blood product required, hematocrit nadir prior to transfusion to assist in ascertaining whether transfusion was necessary, surgical interventions performed, and hospital length of stay were also retrospectively analyzed. Due to the low sample size we used descriptive as opposed to inferential statistics in our analysis. Result: Demographics include male to female ratio of 13:6 and the average age of patients was 11.9 + 4.6 years. Of the nineteen patients who underwent review, eleven (57,89%) children presented with a grade III renal injury, five  with a grade IV injury and three with  grade V injury. Six patients presented with gross hematuria and 3 with microscopic hematuria. Only four patients (22%) required blood transfusions, with the average hematocrit nadir being 31 + 5.3% (24.8-37.8). One of the two patients transfused had a concomitant grade IV splenic laceration with a hematocrit nadir of 24.8% and clinical symptoms consistent with shock. Conclusions:The specificity of the child's anatomy is an aggravating prognostic factor (the kidney is larger in relation to the body cavity than in adults, less protected against the ribs, the muscles of the body and the lower abdomen, the less developed peritoneal and retroperitoneal fatty tissue).It is recommended to initiate conservative treatment (leaching, infusion solution, monitoring) and possibly delayed surgical treatment.Indications for early surgicaly treatment are reserved only for patients with bleeding (absolute) and extravasation (relative).If it is necessary surgical treatment sould be  maximally preserve kidney tissue.

Introduction: Transverse colon volvulus is an uncommon cause of bowel obstruction. Predisposing factors are mental retardation, dysmotility disorders, chronic constipation, and congenital megacolon. Case report: We presented a transverse colon volvulus in a 14-year-old girl with mental retardation. Chronic constipation in neurologically impaired patients was a risk factor predisposing to volvulus. The girl was admitted to our Clinic because of problems that last 4-5 days and was followed by abdominal pain, vomiting and lack of stool. Vomiting was once a day. She was sub febrile up to 37.6°C. On examination, the abdomen was distended, tense, diffusely painful. During the surgery, a 360° clockwise volvulus of the transverse colon was found. After the reduction of volvulus, an enormous transverse colon was resected and protective ileostomy was formed. In the postoperative period, ileostoma functioned a good. The definitive surgical treatment was done on the 20th postoperative day when the occlusion of the ileostomy and transanal biopsy of the rectum was done, which showed the presence of ganglia cells. The patient was discharged from our institution after 1 month. Conclusion: Pediatric patients with neurological conditions and mental retardation present an increased risk of colon transversum volvulus due to chronic obstruction.

Background: An extensive burn is one of the most serious injuries. The modern treatment of pediatric burns is a logical exercise in resuscitation, infection control, surgical wound care, nutrition and psychologic and physical rehabilitation. The conventional methods of local therapy, especially in extensive and deep burns, cannot prevent infection. The fact is that the necrotic burn tissue always gives rise to infection and must therefore be excised. Tangential excision is a diagnostic procedure as well as a surgical preparation of a recipient bed for skin graft.  Clinical parameters of sixty extensively burned children have been evaluated, divided into two groups (surgically and non-surgically treated) and in four subgroups (under and over the 25% TBSA). The following criteria have been used to compare the results: pain, fever, body weight, duration of the hospital stay, wound infenction, laboratory values. Aim of research: The aim of our research was to demonstrate the efficacy of early tangential necrectomy in the treatment of extensive burns in children as well as in preventing the burn diseases. Material and methods: Clinical parameters of sixty extensively burned children have been evaluated, divided into two groups (surgically and non-surgically treated) and in four subgroups (under and over the 25% TBSA). The following criteria have been used to compare the results: pain, fever, body weight, duration of the hospital stay, wound infection, laboratory values. Results: The boys comprised 58.3% of the respondents and the girls were 41,7% of the respondents. The most common cause was the hot liquid of 73.3%, open flame 23.3% and the contact with hot metal 3.3%. The body temperature was significantly higher in control group compared to the examined group (p <0.001) significantly lower hematocrit values in the control group compared to the examined group (p = 0.002).      The results show that hospitalization lasted considerably longer in patients in the control group than in the examined group (p = 0.003). The incidence of bacterial infection of the burns is significantly higher in control compared to the examined group of patients (p = 0.007). The most commonly isolated bacteria in the study group was Staphylococcus aureus (15/30 or 50% of all subjects). Acinetobacter spp. was isolated in 9 patients (30% of respondents). Serratia spp. And Enterococcus Foecalis were isolated in 6 patients (20%). Pseudomonas aeruginosa was isolated in 3 patients (10%). Three patients (10%) did not isolate any bacteria during hospitalization Conclusions: The method of early tangential necrectomy of extensively burned children significantly reduce morbidity and mortality (it improves the general condition of the patient, improves clinical and laboratory parameters, reduces the possibility of infection of the wound, reduces the possibility of sepsis, reduces the length of hospitalization).The most optimal time to perform an early tangential necrectomy is the period between the 4th and the 6th day after the injury. In extensively burned children over 30% of the total body surface, an early tangential necrectomy should be performed on an area of about 20% of the total body surface as a prevention of blood loss due to necrectomy and autotransplantation. With extensively burned children over 40% of the total body surface, taking homotransplants from parents or close relatives reduces morbidity and mortality.

The pseudocyst wall is covered with inflammatory fibrotic tissue, unlike true cysts whose wall is covered with mesothelium. Treatment of abdominal pseudocysts involves resection of the pseudocyst wall and shunt replacement. The above procedure can be done by open or minimal access to the surgical procedure. A 10-year-old girl to whom the VPS is placed comes from long-term abdominal colic and symptoms similar to an acute abdomen. We treated the girl with minimal access to the procedure, performed a resection from the abdominal pseudocyst, and did a VPS replacement. The patient’s postoperative course was satisfactory.

Isolated female epispadias without bladder exstrophy is a rare congenital anomaly affecting 1 in 484,000 females. The presenting features of female epispadias are urinary incontinence and abnormal anatomical features. A 6-year-old girl presented with primary urinary incontinence who on physical examination had a bifid clitoris and labia minora. The vagina and hymen were normal. Voiding cystourethrogram showed no reflux and a funnel shaped proximal urethra. With the diagnosis of isolated female epispadias, one-stage reconstruction of the urethra, bladder neck, labia minora and clitoris was performed.
