Treatment of the congenital thoracic deformity pectus excavatum.

Pectus excavatum is the most common chest wall deformity in the Czech Republic. This chest deformity is typically characterized by a wall depression with sternal rotation. If the excavation of the chest wall does not cause any physical or psychological problems, the patient does not need any specific treatment. However, if the deformity is painful, affects the function of the lungs, heart or results in psychological problems, we can propose an appropriate treatment for the specific age category of the patient. Up to 10 years, we choose a procedure that includes targeted exercises and rehabilitation; in the age group of 10-15 years, we can add to the exercises the vacuum bell therapy according to the patient's wishes and compliance; and in the age category of 16 years and above, the patient can be offered a surgical solution. The Nuss operation (so-called MIRPE - minimally invasive repair of pectus excavatum) is the gold standard in surgical treatment; during this surgery, a patient-shaped bar is inserted retrosternally into the patient's chest under thoracoscopic control and is left for 3 years. The aim of this article is to describe the most common modern methods used in the treatment of patients with pectus excavatum, supplemented by a historical overview.

CT findings predicting lung resection in children with complicated community-acquired pneumonia.

PURPOSE: To investigate computed tomography (CT) features which predict lung resection in children with complicated community-acquired pneumonia. METHODS: A retrospective study of CT findings of patients with complicated pneumonia treated between January 2010 and December 2019. Fisher's exact test and ROC curves were used for statistical analysis. RESULTS: The study cohort consisted of 84 patients who underwent chest CT for complicated pneumonia. Lung resection was performed in 36 patients, 3 patients were treated by lung decortication, 45 patients were cured conservatively. Seven CT features were found statistically significant among the patients who underwent lung resection. 80.5% of patients from the resection group had two or more of these features on the initial CT scan, 64% had three or more. According to ROC analysis, simultaneous occurrence of multiple cavities equal to or greater than 3 cm and lung abscess predicted a pulmonary resection. CONCLUSION: The combination of CT features which clearly predict lung resection are the simultaneous occurrence of multiple cavities ≥ 3 cm and lung abscess. The most common triple combination of CT signs in the resected group of patients were multiple cavities ≥ 3 cm, consolidation of lung tissue and pleural effusion < 3 cm.

[Multidisciplinary approach to surgical disorders of the pancreas in children]. / Multidisciplinární prístup k chirurgickému onemocnení pankreatu v detském veku.

INTRODUCTION: Surgical diseases of the pancreas in children are not common and may be associated with significant morbidity and potential mortality. A multidisciplinary approach is essential for correct diagnosis, surgical strategy and postoperative as well as follow-up care. METHOD: Retrospective analysis of patients operated on due to a pathological lesion of the pancreas focused on diagnostics, operating procedures, postoperative complications, and long-term results. Between 1991 and 2016, eighty-nine children were treated in our department for a pathologic lesion of the pancreas. 39 of them were boys and 50 were girls. RESULTS: Mean age of the patients was 9.3 years (1 month-18.4 years). Patients were followed from the operation to the age of 19, after which they were referred for follow-up to adult specialists. The indications for surgery were trauma in 34 children, solid pseudopapillary tumor in 23 children, biopsy in 10, hyperinsulinism in 8, chronic pancreatitis in 4, pancreatic cyst in 3, insulinoma in 3, carcinoma in 2, and serous cystadenoma and pancreas divisum in one patient. The most frequent procedures performed on the pancreas were distal pancreatectomy in 35 cases, the duodenum-preserving pancreatic head resection in 23 cases, pseudocystogastroanastomosis in 11 cases, 9095% pancreatic resection in 5 cases, Whipple operation in two cases, Puestow procedure in one case, tumor enucleation in one case, and tumor biopsy for cancer in one case. In 5 patients after major pancreatic injury, ERCP and papillotomy with insertion of a stent into the pancreatic duct was performed. 3 patients died, one after a polytrauma with severe pancreatic injury and two patients with pancreatic cancer. CONCLUSION: Pancreatic surgery in children is not a common operation, and individual as well as institutional experience remains limited. After more than 20 years of experience with pancreatic surgery, we believe that close cooperation with surgeons, pediatric gastroenterologists, radiologists, anesthesiologists, intensivist, pathologists and ERCP specialists is necessary for successful diagnosis and treatment of pancreatic disease in children.Key words: pancreas pancreatic surgery in children duodenum preserving head resection of the pancreas.

Technical innovation in minimally invasive repair of pectus excavatum.

The aim of study was to introduce technical innovation of MIRPE which reduces the risk of cardiac injury. Modification of MIRPE method with semiflexible thoracoscope and sternum elevating technique has been used. Volkmann bone hook has been inserted percutaneously to the sternum. The hook elevates the sternum forward and enlarges the retrosternal space for safer passage of thoracoscopically guided introducer. Using semiflexible thoracoscope allows better view from various angles via one site of insertion. During the period 2005-2012, the MIRPE was performed on 29 girls and 151 boys; the mean age at the time of surgery was 15.9 years (range 13-18.7 years). The mean Haller index was 4.7 (range 2.7-20.5). The most common complication was pneumothorax (3.3 %) and the incidence of bar displacement was 2 %. The most serious complication was cardiac perforation when inserting Lorenz introducer. This occurred in a 16-year-old girl; she required urgent sternotomy with right atrial repair and recovered well. External elevation of sternum with the hook was used since this case. Subsequent 113 patients underwent surgery without any serious complications. Technical innovation using semiflexible thoracoscope and hook elevation of the sternum reduces the risk of cardiac injury. The hook opens the anterior mediastinum space effectively and makes the following dissection relatively safe and straightforward.

[Nephroblastoma -  30-years period of its treatment in the University Hospital Motol, Prague]. / Nefroblastom -  30 let lécby ve Fakultní nemocnici v Motole.

INTRODUCTION: Nephroblastoma (Wilms tumor - WT) is the most common solid tumor of kidney in children. We present treatment development of WT at the Department of Pediatric Hematology and Oncology, Charles University in Prague, 2nd Faculty of Medicine and University Hospital Motol (KDHO) in the Czech Republic over 30 years. Patients that were treated prior to access to the International Society of Pediatric Oncology (SIOP) protocols are considered to be the historical group, then we have patients treated according to SIOP 9, SIOP 93-01 and SIOP 2001 protocols as full participants of SIOP studies. PATIENTS AND METHODS: Between January 1980 and April 2009, we treated 330 patients with WT at KDHO: 91 patients in historical group (1980-1988), 94 pts in SIOP 9 (1988-1993), 80 pts in SIOP 93-01 (1994-2001) and 65 pts in SIOP 2001 (2002-2009). Overall survival (OS) and event-free survival (EFS) were analyzed by Kaplan-Meier test. RESULTS: The overall ten-year EFS was 81.2% and OS 87.6%. Fifty-eight patients from the 330 (17.6%) had metastases at diagnosis, EFS without metastatic process was 84.6% compared to 65.4% with metastasis presented at diagnosis (p = 0.0003), OS was 70.7% compared to 91.2% (p < 0.0001). One hundred and seventy patients (51.5%) were treated with preoperative chemotherapy and/or radiotherapy, whereas 158 patients (47.5%) underwent primary nephrectomy; EFS and OS did not differ: neoadjuvant vs primary nephrectomy EFS was 81.2% vs 80.9% (p = 0.85), OS 89.4% vs 85.4% (p = 0.38). Sixty (18%) patients experienced disease recurrence; OS after relapse was 33%. In the historical group, EFS and OS were 85.7% and 91.2%. In patients treated according to the SIOP 9 protocol, EFS and OS were 68.1% and 74.5%, resp. In patients treated according to SIOP 93-01, it was 83.6% and 93.7%, resp. and in patients treated according to 87 SIOP 2001, it was 7% and 95.4% (p = 0.001 and p = 0.0008), resp. CONCLUSION: WT is a well treatable disease. The aim for the future is to maintain the current very good survival while minimizing the treatment intensity.

[Surgical technique changes in the repair of pectus excavatum between 1991 and 2012]. / Zmeny chirurgické techniky pri resení Pectus excavatum v letech 1991-2012.

INTRODUCTION: The aim of this article is a retrospective analysis of the results of three methods used for the repair of pectus excavatum between 1991 and 2012. MATERIAL AND METHODS: 508 patients were operated on at the Department of Paediatric Surgery of the Second Faculty of Medicine, Charles University, and the Teaching Hospital in Motol between 1991 and 2012. 16 patients were older than 19 years (19-28 years). The average age of paediatric and adolescent patients was 14.2 years (5-19 years range). Boys (408) prevailed over girls (82), the ratio being 4.9:1. Open Holcomb technique was used to operate on 87 patients (17%), the Welch method was applied in 208 patients (41%). Minimally invasive repair of pectus excavatum (MIRPE) was used in 213 patients (42%) during the entire period of time. RESULTS: As for the 295 patients operated on by the open Holcomb and Welch method, the outcome was excellent in 239 (81%) of them. A favourable result with a small deformity remaining occurred in 44 patients (15%). Unfavourable result was found in 7 patients (2.5%): in these children, a deep excavation occurred 3-5 years postoperatively. In 5 patients (1.5%) we evaluated the result as recurrent chest wall deformity. The minimally invasive method (MIRPE) produced an excellent result in 182 out of 213 patients (85%). A favourable outcome was observed in 27 (22%), unfavourable result in 1 (0.5%) patient. CONCLUSION: In the last 15 years, minimally invasive repair of pectus excavatum has become popular worldwide. Due to very favourable cosmetic results and a relatively small, gradually decreasing number of complications, the proportion of patients requiring surgery to correct their deformity has risen sharply.

Defect-diaphragmatic ratio: a new parameter for assessment of defect size in neonates with congenital diaphragmatic hernia.

AIM: The aim of our study is to introduce a new objective method of perioperative evaluation of the size of diaphragmatic defect to enable comparison of results among various centres and methods used for diaphragmatic reconstruction. MATERIALS AND METHODS: Prospective observational study of neonates with congenital diaphragmatic hernia (CDH) and respiratory distress within 24 h of birth operated on from January 2009 to December 2011. Weight, length, thoracic shape and the diameters of diaphragmatic defect were measured. To determine the relative size of the defect, a defect-diaphragmatic ratio (DDR = defect area:diaphragm area × 100) was calculated. The measured and calculated data were subsequently compared between Gore-Tex patch group (GT) and primary repair group (PR). Mann-Whitney U test was used for statistical analysis. RESULTS: Forty-seven patients with CDH were admitted during study period. The overall survival rate was 79 % (37/47). Preoperative stabilization was achieved in 85 % (40/47). Survival of operated neonates was 93 % (37/40). Diaphragmatic reconstruction with Gore-Tex patch was used in 7 neonates (17 %), and primary repair in 33 (83 %). Mortality in Gore-Tex group was 29 %; mortality in primary repair group was 3 %. Data of anthropometric measurement were complete in 34 children (5 GT and 29 PR). Significant differences were found between GT group and PR group in the size of diaphragmatic defect with the transverse and sagittal diameters of defect (48.0 ± 5.7 vs. 30.1 ± 5.9, P < 0.00061; 34.0 ± 12.5 vs. 16.0 ± 7.3, P < 0.0022) and DDR (18.29 ± 4.60 vs. 5.77 ± 3.28, P < 0.0005), respectively. CONCLUSION: The value of DDR as an objective criterion of the extent of diaphragmatic defect was confirmed by the close correlation between DDR and feasibility of primary repair in the study group. This objective assessment of defect size may improve comparing various surgical techniques and results of different centres, and thus facilitates sharing experience with management of neonates with CDH.

[Stab wounds in children]. / Bodná poranení u detí.

Injuries are the most serious health risk in children. Injuries are the main cause of death and long term disabilities in children. Fortunately, stab wounds in children are very rare in our country, but they are, in most cases, very serious injuries. Presenting 3 case reports, this article aims to show the danger of stab wounds and how easily sharp objects can penetrate human tissue. In two out of the three case reports, a foreign object was remained inside the wound. When dealing with such injuries, this possibility must be considered the wound must be carefully inspected. When a revision is necessary, it should be carried out using minimally invasive methods in order to save the child from suffering extensive wounding which would result from the classical open approach revision.

Large diaphragmatic defect: are skeletal deformities preventable?

PURPOSE: The aim of study was to compare growth, nutritional status and incidence of chest wall deformities and scoliosis in survivors of large congenital diaphragmatic hernia (CDH) defect (Gore-Tex patch reconstruction) with survivors with smaller defects and primary reconstruction. MATERIALS AND METHODS: An anthropometric study of 53 children who underwent CDH repair in neonatal period was carried out. Weight, height, and skin-fold thickness were measured, scoliosis and chest wall deformity were evaluated. Body mass index (BMI) and thoracic index (TI) were calculated using standard rules. The measured data were compared with national population standard with the use of standard deviation score (SDS). According to the type of diaphragmatic reconstruction, the patients were divided into two groups [Gore-Tex patch (10) versus primary repair (43)]. Student t test and Fisher exact tests were used for statistical analysis. RESULTS: Pectus excavatum was found in 25 (47%) patients, poor posture in 33% and significant scoliosis in 5%. Compared with the population norm, CDH children had a significantly lower body height SDS (mean -0.39, p < 0.05), weight SDS (mean -0.75, p < 0.001), BMI (mean SDS -0.68, p < 0.001) and lower TI (mean SDS -0.62, p < 0.01). Gore-Tex versus primary repair group significantly differed in incidence of pectus excavatum and BMI (PE: p = 0.027, BMI SDS: p = 0.016). A majority of anthropometric parameters (weight, height, thoracic index, and thorax circumference) and incidence of scoliosis and poor posture in children after Gore-Tex patch reconstruction did not significantly differ from children after primary repair. CONCLUSION: The differences in some anthropometric parameters (weight, BMI, and TI) and in the skeletal deformity suggest that the CDH not only disturbs normal lung growth, but also seems to have implications on some other aspects of somatic development. Whether these changes could be related to the type of diaphragmatic reconstruction or rather to the size of the defect remains uncertain.

Diagnostic efficacy of ERCP in cholestatic infants and neonates--a retrospective study on a large series.

BACKGROUND AND STUDY AIMS: Cholestatic jaundice in infants is a serious condition, requiring timely and accurate diagnostic evaluation. Our aim was to determine the safety and diagnostic efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of cholestatic liver disease in neonates and infants. PATIENTS AND METHODS: ERCP procedures in cholestatic infants performed in our endoscopy unit between December 1998 and March 2008 were reviewed retrospectively (n = 104 children, 48 boys, 56 girls; mean age 7 weeks, range 3 - 25 weeks; mean weight 4.05 kg, range 1.5 - 4.8 kg). Endoscopic findings were compared with final diagnoses. Statistical analysis was performed and sensitivity, specificity, positive (PPV) and negative (NPV) predictive values of ERCP were calculated both separately for each diagnosis and on aggregate. RESULTS: Cannulation of the papilla was successful in 95 of 104 patients (success rate 91.3 %). Biliary atresia of any type was found in 51 children (53.7 %), with a sensitivity of 86 %, a specificity of 94 %, a PPV of 96 %, and a NPV of 100 %. Choledochal cysts were found in seven children (7.4 %), with a sensitivity of 100 %, a specificity of 90 %, PPV of 86 %, and NPV of 100 %. Biliary stones were found in seven patients (7.4 %). Other structural pathology was found in six patients, and no abnormality was seen in 24 patients. No severe complications occurred during or after ERCP. CONCLUSIONS: ERCP in cholestatic infants, when performed in an expert center, is a safe and reliable procedure that can detect biliary tract abnormalities (e. g. biliary atresia, bile duct stones or choledochal cysts) with high sensitivity and specificity. Laparotomies can be prevented in infants by demonstrating normal patency of the biliary tract by ERCP or by magnetic resonance cholangiography if improvements in this technique are made.

[Liver transplantations in children using reduced grafts]. / Transplantace jater u detí redukovaným stepem.

AIM: Liver transplantation is a life-saving procedure in patients with end stage liver disease. Five-year survival in patients indicated for transplantation based on standard indication criteria, has reached a rate over 80%. Shortage of suitable grafts remains the main problem in these procedures. While the situation in adult patients is relatively satisfactory, liver transplantations in children, mainly in the low-weight categories, remain a worldwide problem because of the absolute lack of suitable donors. In order to reduce mortality in the youngest patients on the waiting list, a concept of reduction of the adult graft for pediatric use was introduced in the early 1990s. Recent introduction of novel methods, such as split transplantations or transplantations between relatives, has resulted in lower mortality rates in the youngest recipients on the waiting lists. The author assesses a group of patients below 18 years of age, who underwent reduced liver graft transplantations in the Czech Republic. MATERIAL AND METHODS: From 1995 to 2009, a total of 43 patients below 18 years of age underwent transplantations, using 48 liver grafts. Further 17 children were sent abroad for transplantations, where a total of 23 liver grafts were used. Only patients who underwent transplantations using the liver grafts adjusted in IKEM were assessed in the patient group, i.e. 14 patients, resp. 16 liver grafts. Reduction was performed in 13 subjects. One subjects underwent transplantation between relatives and a liver split was used in two subjects. In the lowest weight category up to 10 kgs, 5 liver reductions were performed. OUTCOMES: Out of the total (n = 16), 4 grafts failed (2 were early postoperative failures, ie. within 2 postoperative days and 2 grafts failed in Month 5). The mean graft survival was 65 months. Within the youngest recipient age group (n = 5), no graft failure was recorded. The mean survival time is 26 months. CONCLUSION: Since 2007, the Czech Republic has been providing a program for all patients, including the lowest weight-category pediatric patients. To date data are satisfactory. No graft failure has been recorded in the category of the smallest (up to 10 kgs) pediatric patients.

[Radical surgery and intensive chemotherapy are necessary for successful treatment of osteosarcoma]. / Radikální operacní výkon a intenzivní chemoterapie jsou podmínkou úspesné lécby osteosarkomu.

BACKGROUND: We evaluated the therapeutic results in 44 patients (17 girls and 27 boys) with osteosarcoma from 1997 to 2006.Their average age was 12.8 years (2.5-20.2). 41 patients had localised disease and 3 had primary metastases. PATIENTS AND METHODS: We treated our 44 patients using CCG 7921 POG 9351 INT 0133, the therapeutic protocol of the North American cooperative Children's Oncology Group.The median of the follow up was 5.5 years (2-11 years). RESULTS: 40 patients went into complete remission. 19 patients suffered relapses. Of these, 17 patients died - 15 progressed, 1 died due to treatment-related toxicity, 1 died due to secondary acute myeloid leukaemia. As a whole, the patients had a 5-year overall survival rate (OS) of 58.4% and a 5-year event free survival rate (EFS) of 46.7%. The patients with localised extremity osteosarcoma (n = 40) had a 5-year EFS rate of 51%. The patients with good histological response (n = 22) had a 5-year EFS rate of 63.6%, while patients with poor histological response (n = 18) achieved a 5-year EFS rate of 30.5% (p = 0.009). CONCLUSION: The results of treatment of patients with localised extremity osteosarcoma and patients with good histological response to preoperative treatment were very good. The prognosis of patients with axial localisation and metastatic involvement was poor.

Lipoblastoma in children: an analysis of 5 cases.

Lipoblastoma is a very rare benign tumour that is caused by embryonal fat. The present five cases of lipoblastoma operated on during the years 1996-2005. The localization of the lipoblastomas in our series were very unusual. A six-monthold girl with giant mediastinal lipoblastoma; a two-year old boy with very rare lipoblastoma of the kidney; a three-year old boy with mesenterial lipoblastoma; a seven-year old boy with mesenterial lipoblastoma; and an eight-week old girl with perineal localization. Histological diagnosis can be difficult. The basic differential diagnosis is to be made between lipoblastoma, myxoid, and round cell liposarcoma. In our sample group of patients all lipoblastomas were successfully and completely removed and we did not see any recurrence of the tumours. In only one case was more radical surgery needed. One patient with mesenterial lipoblastoma had to undergo a 30 cm long resection of the small intestine.

Surgical management of major pancreatic injury in children.

INTRODUCTION: Major or complicated pancreatic trauma in children is uncommon and management strategies remain controversial. The aim of this study was to evaluate our experience with both early and delayed surgery in these pediatric cases. METHODS: We carried out a retrospective analysis of data of pediatric patients with major or complicated pancreatic injury operated on between January 1994 and December 2005 in our pediatric trauma center. RESULTS: Thirteen children (9 boys and 4 girls) with a mean age of 8.5 years (range 3 - 16 years) were operated for major or complicated pancreatic injury. The extent of injury was: grade II (major contusion without duct injury or tissue loss) in 4 children; grade III (distal transection) in 5 children and grade IV injury (proximal transection) in four patients. Pseudocyst developed in 8 children: 4 with grade II injury, 2 with grade III injury and 2 with grade IV injury (one with abdominal pseudocyst and one with an abdominal and a mediastinal pseudocyst). Early diagnosis and operation was achieved in 5 cases, while delayed diagnosis and operation occurred in 8. Three children underwent cystogastrostomy; 6 had a spleen-sparing distal pancreatectomy and 4 had resection with Roux-en-Y jejunostomy drainage. Endoscopic retrograde cholangiopancreaticography (ERCP) was the most useful diagnostic tool in assessing ductal injury. There were no deaths or long-term morbidity in our group of patients. CONCLUSIONS: Our results support the view that early operation is important in ductal pancreatic injury. We recommend transferring children with a suspected ductal injury to a tertiary center with experience in both pediatric ERCP and pancreatic surgery.

[Method of approximative intestinal anastomosis in experimental model]. / Metoda aproximacní strevní anastomózy v experimentálním modelu.

AIM: A technique of approximative anastomosis in witch integrity and continuity of bowel is achieved with limited number of interrupted seromuscular stitches was evaluated in experimental study. MATERIAL AND METHODS: Small bowel anastomosis were performed in twelve rats (Wistar, male) with weight range 197-242 g. An approximative anastomosis in the ileum of six rats was performed with five seromuscular-interrupted sutures only; in the second study group anastomosis was performed with conventional technique of interrupted sutures. The approximative anastomosis was evaluated concerning operating time, anastomotic healing, bursting pressure and adhesions in comparison to the conventional anastomosis. Statistics was calculated with Anova test. RESULTS: All anastomosis in both group healed well without obstruction. The median operating time needed for approximative anastomosis was shorter (31.7 +/- 1.6 minutes versus 35.2 +/- 1.5 minutes, p = 0.002). The strength of approximative anastomosis after 7 days was 249 +/- 39 torr; strength of standard anastomosis was 218 +/- 23 torr (p = 0.118). There were no significant differences in the others evaluated parameters between two study groups. CONCLUSION: In the animal model presented, the approximative anastomosis shows time saving alternative to standard anastomosis, with the same parameters of anastomotic strength, healing, and adhesions.

Congenital solitary liver cysts.

AIM: The aim of the study was to describe clinical and pathological findings in children with rare congenital solitary liver cyst. MATERIAL AND METHODS: Six children with congenital liver cyst were treated at the authors' institution from 1995 to 2002. Clinical records and operative findings of these patients were reviewed retrospectively. RESULTS: Age at presentation ranged from neonatal to 14 years, and there were four girls and two boys. Hepatomegaly was the most common symptom in neonates while the older children presented with abdominal pain. Ultrasound was conclusive for diagnosis in all children, prenatal ultrasound in three. Intrahepatic cyst was found in five children. Partially extrahepatic cyst in the porta hepatis was found in one. The cyst diameters varied from 8 to 10 cm. Cysts were excised via an open abdominal approach in all patients. Histological findings confirmed the diagnosis of congenital liver cyst. Columnar epithelium was found in newborns while atrophic changes of epithelial lining were seen in older children. In a case of a 13-year-old girl the cyst was lined by metaplastic squamous epithelium with foci of slight dysplasia. Immunohistochemical studies were available in three recent children with positive findings in all of them. The postoperative course was uneventful in all patients. The follow-up period ranged from 36-120 months and no recurrence was observed. CONCLUSION: With appropriate selection of symptomatic patients, total excision of a congenital liver cyst is a safe procedure with excellent long-term results. Given the possibility of malignant degeneration of a congenital liver cyst we recommend its surgical excision in most cases.

[Surgical complications following oesophageal replacement by stomach in childhood]. / Chirurgické komplikace po náhrade jícnu zaludkem v detském veku.

AIM: Assessment of surgical complications and options for their therapy following replacement of oesophagus by stomach. METHODOLOGY AND MATERIAL: A retrospective study of clinical and pathological data collected from 25 children, who underwent replacement procedures of their oesophagus by stomach during the 1992-2005 period. 18 subjects were indicated for the procedure for oesophageal atresia with large stubs distance and 7 subjects were indicated for extensive oesophageal strictures following acid burns. RESULTS: The study group included 25 children whose mean age at the time of the procedure was 12.5 years (the age range 8 to 13.3 years). Early postoperatively, a fistule in the oesophageal anastomosis region was confirmed in 7 subjects (28%), however, in all cases it healed successfully on conservative management. In five cases (20%), a stricture in the pyloric region developed and in 4 cases it was managed using balloon dilation. During the long-term follow up period, oesophageal anastomosis strictures were diagnosed in 9 children (36%). The problem was managed using repetitive balloon dilations. One child was operated for ileus with adhesions and in one child, a nutritional jejunostomy had to be re-conducted. One girl exited at home, a year following the procedure, due to respiratory arrest on aspiration. CONCLUSIONS: Transposition of the stomach is a suitable method of choice for oesophageal replacement in childhood, providing good quality of life for majority of patients. Early and late surgical complications correspond with a degree of seriousness of the disorder and require treatment and long term follow up to be conducted in a specialized clinic.

[Morgagni diaphragmatic hernia in childhood]. / Morgagniho bránicní kýly v detském veku.

The aim of this work was to retrospectively assess clinical and anatomical features of children with Morgagni congenital diaphragmatic hernias. The study group included 5 boys and 3 girls, aged between 5 months and 13 years, at the time of the diagnosis. Morgagni diaphragmatic hernia was diagnosed with non-acute symptoms in 8 children. A retrosternal defect of the diaphragm was left-sided in 7 subjects and bilateral in 1 boy. A hernial sac was found in 6 children. In 3 subjects, the hernial sac contained the liver, in 2 subjects the omentum, in 2 subjects the transverse colon and small intestinal loops and in one child it contained the transverse colon with the omentum. In all cases, the diaphragmatic defect was closed using primary plasty. All subjects healed without complications. A differential diagnosis of congenital Morgagni hernia must be considered in children with unusual respiratory and gastrointestinal symptoms with abnormal x-ray findings on chest examination. A stricture of the congenital Morgagni diaphragmatic hernia is rare, and was not recorded in our group.

[Living relative donor for liver transplantation in paediatric recipient]. / Transplantace jater dítete od zivého príbuzenského dárce.

Paper refers the first in Czech Republic liver transplantation in a child with the donor being the close living relative - the father. Indication was the chronic liver failure caused by biliary atresia after the Kasai procedures, which enabled the child to survive two years. Liver segments II. -III were transplanted with favourable postoperative development. Within the following twenty months the nutrition status and the psychomotor development of the child significantly improved. Authors discuss present situation and results of the paediatric liver transplantation in the world.

Long-term outcomes of balloon dilation of esophageal strictures in children.

RATIONALE AND OBJECTIVES: The purpose of this study was to determine the long-term success of the use of angioplasty balloons for dilation of esophageal strictures in children. MATERIALS AND METHODS: The authors studied 24 children who had undergone fluoroscopically guided angioplasty balloon dilation of esophageal strictures. Ten children had stricture of the anastomosis after surgical repair of esophageal atresia; five had achalasia; three had strictures due to gastroesophageal reflux; three had corrosive strictures; two had congenital stenosis; and one had stricture after radiation therapy. Success was defined as resolution of the dysphagia a year after dilation. RESULTS: A year after the last dilation, 15 of the 24 children had no dysphagia. Patients in whom treatment was successful included eight children with strictures after surgery for esophageal atresia, one with achalasia, three with strictures caused by gastroesophageal reflux, one with a corrosive stricture, one with congenital stenosis, and one with a stricture resulting from radiation therapy. CONCLUSION: The long-term results of balloon catheter dilation are highly successful in patients with stricture after surgical repair of esophageal atresia and stricture due to gastroesophageal reflux. Dilation is not as valuable in the treatment of esophageal strictures resulting from other causes.
