RESUMO

BACKGROUND: Partial internal biliary diversion (PIBD) is an alternative approach for the treatment of devastating pruritus in patients with progressive familial intrahepatic cholestasis (PFIC). In these patients quality of life can be improved and progression of liver disease can be delayed while waiting for liver transplantation. The aim of our study was to evaluate six patients with PFIC who have undergone PIBD in long-term follow-up. METHODS: Retrospective review of the records of six patients who underwent PIBD for PFIC between 2008 and 2010 was conducted to evaluate age, growth, clinical and laboratory studies for long-term outcome. RESULTS: Serum postoperative bile acid levels were reduced from a mean 340.1µmol/L (range 851-105) preoperatively to a mean of 96.3µmol/L at postoperative fifth year. The difference between pre- and postoperative bile acid levels was statistically significant (p=0.018). AST decreased from 79.1U/L (range 43-150U/L) to 64.6U/L (range 18-172U/L), ALT decreased from 102.8U/L (range 35-270U/L) to 84.6U/L and total bilirubin decreased from 2.9µmol/L (range 0.35-6.4µmol/L) to 1.53µmol/L (range 0.3-2.4). Again, the decrease in total bilirubin levels was significant (p=0.043). Pruritus was diminished from a mean of +4 (range 4-4) preoperatively to a mean of +2 (4-0). One patient who underwent liver transplantation owing to relapsing pruritus died from postoperative sepsis in the early postoperative period at the fifth year after PBID. Five symptom-free patients have not required liver transplantation at a mean period of 6.1±0.83years (5.1-7.0years) follow-up. CONCLUSION: PBID is an effective surgical procedure in the long-term and can delay the need for liver transplantation in children with PFIC by reducing jaundice and pruritus.

RESUMO

AIM: This study was designed to investigate the factors affecting the prognosis in neonates with congenital diaphragmatic hernia (CDH) who were treated in our clinic. These factors included prenatal lung-head ratio (LHR), prenatal stomach and liver presence in the thorax, blood gases in the first 24 h and the modified ventilation index (MVI). MATERIAL AND METHODS: The study was carried out retrospectively in 30 neonates with prenatally diagnosed left CDH who were treated in our clinic between January 2007 and 2013. Data were collected, evaluated, and statistically analyzed for gender, birth weight, gestational age, prenatal LHR, prenatal presence of stomach and liver in the thorax, postnatal initial blood gases in the first 24 h and MVI. RESULTS: The median LHR for non-survivors was 1.49 and for survivors 1.51. No statistically significant difference in LHR was detected between survivors and non-survivors. In 19 neonates, prenatal ultrasonography (USG) revealed intrathoracic stomach, and 9 of these infants died. Intrathoracic liver was seen in 15 neonates, and 9 of these died. A statistically significant difference was not found between survivors and non-survivors in the intrathoracic liver or intrathoracic stomach neonates. A comparison between the non-survivors and survivors showed a median pH value of 7.10 in non-survivors and 7.24 in survivors (p = 0.002). The median PaCO2 value was 69.4 mm Hg in non-survivors and 51.9 mm Hg in survivors (p = 0.01). There were statistically significant differences in pH and PaCO2 values. The median value of MVI was 33 in survivors and 100 in non-survivors. There was a statistically significant difference between overall non-survivors and survivors in the MVI value (p < 0.05). CONCLUSIONS: Based on the findings, postnatal pH, and PaCO2 and MVI values are favorable prognostic factors in CDH in our selected group of patients.

RESUMO

PURPOSE: The purpose of the study was to evaluate our experience with enteric duplication cysts in 40 children during the past 26 years, while assessing the variability of their presentations and to propose an algorithm for surgical management. METHODS: We retrospectively analysed sex, age, clinical presentations, duplication site, surgical treatment, presence of ectopic tissue, complications, associated anomalies, and prognosis of 40 patients with gastrointestinal tract duplications who were surgically treated in our clinic. RESULTS: Overall, there was a predominance of boys (28 males, 70 %; 12 females, 30 %). The presenting symptom was vomiting in 23 patients, rectal bleeding in 11 patients, abdominal mass in 10 patients, abdominal pain in 9 patients, constipation in 6 patients, cough in 2 patients, and respiratory distress in 2 patients. In 30 patients, a complete excision of the cyst with additional segmental intestinal resection and anastomosis was performed. Cystectomy was performed in seven patients, while complete excision of the cyst with additional wedge resection was performed in two. A Wrenn procedure (mucosectomy) was performed in one patient. CONCLUSION: Due to the variability in the site of enteric duplications, a wide range of presenting symptoms can exist, which is challenging for diagnosis. In children with a diagnosis of acute abdomen, enteric duplication cysts should be considered, and these children should be further investigated for additional skeletal, urogenital, and gastrointestinal system pathologies. Surgical treatment depends on the site and type of the cyst.

RESUMO

Introduction. The aim of the study was to evaluate our children who are operated on for anomalous congenital band while increasing the awareness of this rare reason of intestinal obstruction in children which causes a diagnostic challenge. Patients and Methods. We retrospectively reviewed the records of fourteen children treated surgically for intestinal obstructions caused by anomalous congenital bands. Results. The bands were located between the following regions: the ascending colon and the mesentery of the terminal ileum in 4 patients, the jejunum and mesentery of the terminal ileum in 3 patients, the ileum and mesentery of the terminal ileum in 2 patients, the ligament of Treitz and mesentery of the jejunum in one patient, the ligament of Treitz and mesentery of the terminal ileum in one patient, duodenum and duodenum in one patient, the ileum and mesentery of the ileum in one patient, the jejunum and mesentery of the jejunum in one patient, and Meckel's diverticulum and its ileal mesentery in one patient. Band excision was adequate in all of the patients except the two who received resection anastomosis for intestinal necrosis. Conclusion. Although congenital anomalous bands are rare, they should be considered in the differential diagnosis of patients with an intestinal obstruction.

RESUMO

INTRODUCTION: The transanal endorectal pull-through (TERPT) procedure, the latest advancement in the surgical treatment of Hirschsprung's disease, has replaced most other surgical techniques in the last decade. PATIENTS AND METHODS: Between October 2002 and March 2014, a total of 22 patients diagnosed with Hirschsprung's disease underwent a one-stage TERPT operation. RESULTS: Resected segments included the rectosigmoid (seven patients), the descending colon (10 patients), and the transverse colon (five patients). The minimum length of the resected segments was 15 cm and the maximum length was 65 cm. The mean length was 39.18 ± 12.05 cm. Following surgery, the start of oral ingestion was 1-8 days (mean 3 ± 1.69 days) and the hospital stay after the operation lasted 4-11 days (mean 7.04 ± 2.05 days). The mean follow-up period was 48 ± 6 months (range of 24-166 months). Out of 22 patients, three patients had an anal stricture, which responded to anal dilatations; three patients had an enterocolitis episode that required hospitalization; two patients experienced constipation; and two patients had incontinence/soiling. CONCLUSION: Our data suggest that the TERPT operation can be safely performed in terms of long-term complications.

RESUMO

Introduction The aim of this study was to review a single institution's experience with surgical interventions in children with achalasia and to determine treatment strategies for this rare disorder. Patients and methods This study is a retrospective analysis of 22 cases of childhood achalasia from 1991 to 2013. The patients were evaluated in terms of age, symptoms, interventions, intraoperative complications, and recurrent dysphagia. Results There were 13 boys and nine girls (7 months to 17 years old). The clinical symptoms were vomiting (68%), dysphagia (36%), wheezing (18%), coughing (13%), and weight-loss (13%). The mean duration of symptoms was 2.4 years (1 month to 6 years). A barium contrast X-ray study was performed in all of the patients. Oesophageal manometry was performed in eight patients. Six patients underwent multiple oesophageal dilatations (ED) as a first intervention. A Heller myotomy (HM) and fundoplication were performed in all the patients except two patients who recovered with dilatation. In the long term, one patient had a stricture due to the operation and had to undergo a reoperation. Of the Heller myotomy patients, one had a recurrent stricture that responded to dilatation. No other complications were present. All the patients are now asymptomatic. Conclusion Early diagnosis and prompt surgical treatment is important to prevent growth impairment in childhood achalasia cases. A Heller myotomy followed by a partial anti-reflux procedure is an effective treatment for achalasia in children. Based on our experience, it is superior to oesophageal dilatation therapy.

RESUMO

Triple A syndrome, also known as Allgrove syndrome, is a rare disease, and presents mainly in children. Its cardinal symptoms are achalasia, alacrima, and adrenocorticotropic hormone (ACTH) insensitivity. We report three cases of Triple A syndrome. Our aim is to inform pediatric surgeons about the existence of this rare syndrome and to highlight the need for suspicion of alacrima and ACTH insensitivity in cases of pediatric achalasia. Triple A syndrome should be considered in patients presenting with achalasia. Alacrima should be investigated by a Schirmer test, and adrenal dysfunction should be tested in cases of suspected triple A.

RESUMO

BACKGROUND: Paediatric tracheobronchial tumours are very rare, and pneumonectomy and lobectomy procedures are rarely indicated due to their surgical difficulties and high sequelae. Bronchoplastic techniques preserving lung parenchyma allow the resection and reconstruction of the main bronchi and carina. CASE PRESENTATION: Here, we present a 6-year-old boy suffering from a carcinoid tumour of the right main bronchus which was successfully managed with a right upper sleeve lobectomy and a 4-year-old girl with an endobronchial carcinoid tumour narrowing the left main bronchus that received a sleeve resection of that bronchus. CONCLUSION: Bronchoplastic techniques are widely used in adults, can be very successful in paediatric patients where the preservation of the lung parenchyma is more important.

RESUMO

Wilms' tumor is a relatively common malignancy among childhood cancers. However, intracardiac extension of the lesion is rare and challenging. In this report, the authors present a successful management of intracardiac extension of Wilms' tumor in a 3-year-old child using cardiopulmonary bypass and deep hypothermic circulatory arrest. The authors also reviewed the published literature on Wilms' tumor with cardiac extension, which were managed by cardiopulmonary bypass and deep hypothermic circulatory arrest to provide an optimum management plan in this challenging condition.

RESUMO

BACKGROUND: This study aims to evaluate the outcomes of pulmonary metastasectomy resections in pediatric patients. METHODS: We retrospectively reviewed the medical records of 43 children who were operated on in the Pediatric Surgery Clinic between January 1988 and 2014. Forty-three children (26 boys; 17 girls; mean age 10±4.24 years, range 6 months-18 years) who underwent pulmonary metastasectomy resection were included in the study. The patients were evaluated based on age, gender, history of disease, surgical procedures, complications, duration of hospitalization, duration of chest tube placement, and procedure outcome. RESULTS: Indications for pediatric resections were oncological. Metastasis was secondary to Wilms' tumor in 14 patients, osteosarcoma in 7 patients, Ewing's sarcoma in 5 patients, rhabdomyosarcoma in 5 patients, lymphoma in 3 patients, hepatoblastoma in 2 patients, and other tumors in 7 patients. A total of 59 thoracotomies were performed. Approaches utilized included unilateral posterolateral thoracotomy (n=33), bilateral posterolateral thoracotomy (n=8), and sternotomy (n=2). Wedge resection was the procedure of choice (n=44). In selected cases, 11 segmentectomies, 3 lobectomies, and 1 pneumonectomy were performed. There was no perioperative mortality. One patient suffered prolonged air leak and three patients from fever. All patients received chemotherapy. Radiotherapy was administered to 16 patients (37.2%). Of those 16 patients, 7 had Wilms' tumor, 6 had Ewing's sarcoma/PNET, and 3 were rhabdomyosarcoma patients. During a median follow-up of 3 years, the overall survival was 74.4%. CONCLUSIONS: Multidisciplinary treatment involving pediatric oncologists, surgeons, and radiation oncologists is necessary to obtain positive results in children who have pulmonary metastases of oncological diseases. Wedge resection is a suitable option for children because less lung tissue is resected.

RESUMO

AIM: An experimental study was performed to evaluate the protective effects of probiotics on gut mucosa in peritonitis through antioxidant mechanisms. METHODS: Thirty-two male Wistar albino rats were divided equally into four groups. The rats in Group 1 (control group) underwent laparotomy only. In group 2 (peritonitis group), peritonitis was induced in the rats by the cecal ligation and puncture (CLP) model. In group 3, the rats were treated with probiotics for five days after CLP-induced peritonitis. The last group of rats (group 4) were fed probiotics for five days before the CLP procedure and five days after the surgery. On the fifth day after surgery, all rats were killed, and tissue samples from the terminal ileum were obtained to evaluate the activities of myeloperoxidase (MPO), malondialdehyde (MDA), and glutathione (GSH). Histopathologic examinations were also performed to evaluate the grade of intestinal injury. RESULTS: Myeloperoxidase and MDA activities were increased, GSH concentrations were decreased in group 2, compared with group 1. Intestinal MPO activities in group 4 were decreased compared with group 1 and group 2, indicating a reduction in oxidant activity. Malondialdehyde decreased in group 3 and decreased even more in group 4, compared with the peritonitis group (group 2). Glutathione concentrations were increased in group 4 compared with group 2 and group 3 (p < 0.05). The Chiu scores of the probiotics groups, groups 3 and 4, were lower than those in group 2, indicating reduced mucosal damage in the probiotically fed groups. CONCLUSION: Probiotics have protective effects in peritonitis, which may be related to antioxidant mechanisms. This antioxidant effect of probiotics might occur when pre-conditioning with probiotics before peritonitis because there is sufficient time to prepare the tissues for oxidative damage.

RESUMO

PURPOSES: In this experimental study, we investigated the role of ozone therapy in hepatic fibrosis caused by biliary obstruction. MATERIALS AND METHODS: In this study, 21 male Sprague-Dawley rats were divided equally into three groups. In the control group, only laparotomy was performed and intraperitoneal cavity is washed with 1 mL of saline. In the sham group (SG), common bile duct is binded with laparotomy and no treatment is given afterward. In the experimental group (EG) after the binding of common bile duct with laparotomy, 1 mg/kg dose and 50 mg/mL concentration of ozone were applied rectally for 21 days. Hepatic tissue sample and intracardiac blood samples were collected from all animals at postoperative 21st day with relaparatomy. RESULTS: When we compared the experiment to SG, we detected a decrease in aspartate aminotransferase, alkaline phosphate (ALP), total bilirubin, and direct bilirubin levels in the EG, however, only the decrease in total bilirubin levels were statistically significant (p = 0.025). Histopathological examination of livers of rats in the EG showed lower level of hepatic fibrosis and inflammation. In the SG, incomplete cirrhosis was detected in 57.1% of the rats, whereas in the EG, no cirrhosis was detected. Immunohistochemically, periportal inflammation was 100% in the SG, whereas it was seen (3/7) 42.9% in the EG. A significant decrease in positive α-smooth muscle actin reaction was observed in ozone-treated group compared with SG. CONCLUSION: We suggest that ozone can decrease the hepatic destruction levels in experimental model of biliary obstruction.

RESUMO

Infectious diseases are the leading cause of FUO. A case of prolonged fever with hepatic and pulmonary tuberculosis as a final diagnosis is herein presented. A 4-year-old, otherwise healthy boy presented with an axillary temperature of up to 39.5ºC for the previous 3 weeks. His medical history revealed an occasional increase in body temperature up to 38.5ºC for the last 6 months. Physical examination revealed coarse breath sounds on the basal lung area. Chest X-ray showed mediastinal lymphadenomegaly and computed tomography revealed paratracheal conglomerated lymph nodes and a groundglass appearance on the right lung. There were multiple contrast-enhanced, hypoechoic nodules with central necrosis in the liver parenchyma on abdominal magnetic resonance imaging. Open liver biopsy yielded chronic granulomatous inflammation compatible with pathological findings of tuberculosis infection. The culture specimen was positive for Mycobacterium tuberculosis. The patient improved rapidly after antituberculous therapy was initiated. Tuberculosis, especially in its disseminated form, poses a distinct diagnostic challenge in cases of prolonged fever with unproven etiology, and thus persistence should be exercised in disclosing the cause of such fevers.

RESUMO

BACKGROUND/AIMS: To contribute to the diagnosis and treatment of pediatric abdominal tuberculosis cases by assessing the clinical, laboratory, and radiological features of patients who presented at our clinic and were diagnosed with abdominal tuberculosis. MATERIALS AND METHODS: Clinical, laboratory, and radiological features were reviewed retrospectively for 35 patients diagnosed with abdominal tuberculosis and followed up at the Pediatric Infectious Diseases Clinic between January 1987 and August 2012. RESULTS: The study group included 16 female (45.7%) and 19 male (54.3%) patients with an age range of 6 months to 16 years (mean: 9.77±4.36 years). Twenty-nine patients were diagnosed with tuberculosis peritonitis, five patients with intestinal tuberculosis, and one patient with pelvic tuberculosis. The most common signs and symptoms were ascites, abdominal pain, abdominal distention, weight loss, and fever. Mean duration of the complaints was 109 days (range: 10 days to 3 years). CONCLUSION: Abdominal tuberculosis is a disease with an insidious course without disease-specific clinical and laboratory signs. When the disease is suspected, laparoscopy or laparotomy could be helpful in diagnosis. Employing ultrasound and computed tomography signs, abdominal tuberculosis should be included in differential diagnoses in regions with a high incidence of tuberculosis when there is abdominal pain, weight loss, ascites, history of contact with individuals with tuberculosis, and positive tuberculin skin test when patients have not been Bacillus Calmette Guerin BCG vaccinated.

RESUMO

OBJECTIVE: To investigate the effects of probiotics on bacterial translocation in the obstructive common bile duct with comparison to an enteral product containing arginine and glutamine. MATERIAL AND METHOD: In our study, 40 Sprague-Dawley rats each weighing 250-300 g were used. Animals in Group 1 (sham) were laparatomized and fed standard chow supplemented with physiologic saline at daily doses of 2 ml through orogastric tube for 7 days. Common bile ducts of the animals in the other groups were ligated with 3/0 silk sutures. Group 2 (control group) was fed standard chow supplemented with daily doses of 2 ml physiologic saline. Group 3 (probiotic group) was fed standard chow supplemented with a probiotic solution (Acidophilus plus) containing strains of Lactobacillus acidophilus, Bifidobacterium bifidum and Lactobacillus bulgaricus at a daily doses of 2 × 10(9) colony forming units (CFU). Group 4 (formula group) was fed only an enteral solution (Stresson Multi Fiber) containing glutamine, arginine and a medium-chain fatty acid at daily doses of 2 g/kg. At the end of the 7th day, all animals were relaparatomized, and to determine bacterial translocation, aerobic, and anaerobic cultures were obtained from the specimens of mesenteric lymph nodes, intestinal mucosa, and blood samples. Smear cultures prepared from caecum were examined to determine the number of CFU. Finally, for histological examination specimens were excised from terminal ileum, and oxidative damage was assessed in liver tissues. Afterwards all animals were killed. RESULTS: Moderately lesser degrees of bacterial translocation, and mucosal damage were seen in Groups 3, and 4 relative to Group 2 (p < 0.05). In Group 4, any difference was not seen in the number of cecal bacteria relative to baseline values, while in Group 3, significant decrease in cecal colonization was seen. Among all groups, a significant difference between levels of malondialdehyde, and glutathione was not observed. CONCLUSION: At the end of our study, we have concluded that both probiotics, and enteral diets which contain immunomodulators such as glutamine, and arginine alleviate bacterial translocation, and impairment of intestinal mucosa.

RESUMO

BACKGROUND: We aimed to evaluate the microbiological and immunological effects of tissue plasminogen activator (tPA) in a rat model of peritonitis. METHODS: Twenty-four male Wistar albino rats were divided equally into three groups. Peritonitis and thereafter laparotomy and partial omentectomy were performed in all rats. The control group (C) had no further treatment. The antibiotics group (A) received metronidazole and ceftriaxone. The antibiotic and tPA group (A+T) received the same antibiotics as well as tPA. For microbiological and immunological analysis, blood samples were obtained at the 24th hour, and peritoneal fluid samples were obtained at the 24th and 72nd hours. On the fifth day after surgery, all rats were sacrificed, and the macroscopic findings of the peritoneal cavity were recorded. RESULTS: The mean number of intraperitoneal abscesses was significantly higher in the control group and the lowest in the two treatment group (A+T). The levels of cytokines were not significantly different between groups. Giving tPA reduced the number and sizes of the abscesses with no significant difference in inflammatory response. CONCLUSION: In this experimental peritonitis model, it can be postulated that tPA decreased abscess formation without exaggerating the inflammatory response.

Primary mediastinal malignancies are rare tumors and can originate from any mediastinal organ or tissue such as thymic, neurogenic, lymphatic, germinal, or mesenchymal. The authors reviewed all cases of primary pediatric mediastinal masses diagnosed over a 25-year period to determine the pattern of presentation, the histology, and the outcome of the surgical treatment. In this study, 120 primary pediatric mediastinal mass cases diagnosed between 1985 and 2011 are retrospectively evaluated according to their age, sex, symptoms, anatomical location, surgical treatment, and histopathological evaluation. The median age of the patients was 5.8 years. There were 34 benign and 86 malign tumors. Thirty patients were asymptomatic. Common symptoms in the patients were cough, dyspnea, fatigue, fever, abdomen pain, back pain, and neurological symptoms. According to their origins, they were presented as neurogenic tumors (38.3%), lymphomas (18.3%), undifferentiated sarcomas (15%), germ cell tumors (7.5%), and the other tumors (22%) thymic pathologies, lymphangiomas, rhabdomyosarcomas, lipomas, hemangiomas, and Wilms' tumor. Complete resection of the tumor was performed in 86 patients, partial resection of the tumor was the intervention in 11 patients. In 23 patients, biopsy was undertaken. Because of the high incidence of asymptomatic or nonspecific presentation such as the upper airway disease, the presentation of a mediastinal mass in children may be challenging. Neurogenic tumors or lymphomas are indicating surgery, if possible complete resection, for both benign and malignant conditions. Although surgery is the mainstay of therapy for most mediastinal tumors, an experienced multidisciplinary approach is necessary.

RESUMO

A cytological diagnosis is essential for a definitive diagnosis in children who have paratracheal lesions. Thirteen pediatric patients were biopsied using cervical mediastinoscopy. Age, gender, preoperative diagnosis, and postoperative biopsy results and complications were reviewed. Five patients had mediastinal lesions residuing or recurring after chemotherapy for either Hodgkin disease or non-Hodgkin lymphoma. In 2 of these patients, the diagnosis was recurrent disease. Among the 8 patients presenting with a paratracheal mass or enlarged lymph nodes, histopathologic diagnosis showed tuberculosis in 3 children, Hodgkin disease in 2 children, and histiocytosis X and non-Hodgkin lymphoma 1 patient in each. This study shows that cervical mediastinoscopy gave 100% correct diagnosis for mediastinal residual malignancies or uncommon forms of mycobacterium tuberculosis with paratracheal masses.

RESUMO

PURPOSE: Congenital tracheoesophageal fistula (TEF) without esophageal atresia is commonly known as "H" type. This is extremely rare in infants. The rarity of the condition, its nonspecific symptomatology, and limitations in its demonstration by contrast radiology and endoscopy contribute to delays between first presentation and confirmation of the diagnosis. Our aim was to demonstrate a congenital H-type tracheoesophageal fistula by using Tc-99m sulfur colloid scintigraphy. MATERIALS AND METHODS: A case report. RESULTS: A preterm female infant was born by cesarean section at 34 weeks gestation. After many attempts of feeding, she developed apnea, resolving spontaneously, peroral cyanosis, pallor, hypersalivation, and abdominal distension, even when she was being fed by an orogastric tube. With this complex symptomatology, she was suspected to have an H-type TEF. Because of prematurity and recurrent respiratory problems of the infant and the high risk of aspiration of contrast material during a cineradiographic procedure, and also because of the invasive nature of the endoscopic procedure as well as the requirement of general anesthesia, the diagnosis was made by using Tc-99m sulfur colloid scintigraphy and confirmed at operation. CONCLUSION: Demonstrating a congenital H-type tracheoesophageal fistula by using radionuclide imaging is an easily applicable technique.
