Minimally invasive techniques have now become standard for the treatment of many surgical conditions in children. There are a few studies that describe the utility of laparoscopy in BAT in children. In this article, we describe the complete laparoscopic surgical treatment of two patients after a single blunt abdominal trauma, both with bowel perforation. In both cases, the perforation was identified and closed, one laparoscopically with an ongoing suture, the second jejune perforation was closed by laparoscopic-assisted techniques. Both patients had an uneventful postoperative recovery. Therapeutic laparoscopic treatment of patients with upper gastrointestinal perforation is feasible. We hypothesize, that diagnostic laparoscopy provides important information for the treatment of children with abdominal trauma and is accompanied by improved diagnostic accuracy, reduction of nontherapeutic laparotomy rates, and a reduction of morbidity. Minimally invasive surgery in children after BAT is suitable for hemodynamic stable patients, could improve pain scores, cosmetic effect, shorter hospital stays, shorter operative times and shorter return to school/activities. However, at any point in the patients care, in case the unstable hemodynamic is encountered, exploratory laparotomy is the procedure of choice.Key words: miniinvasive surgery blunt abdominal trauma - laparoscopy bowel perforation.

Neural tube defects represent group of congenital diseases with relatively high incidence in population. Authors assess world and Slovak literature and statistical facts about the epidemiology of NTD and compare them with their own results of retrospective study performed in Children's Hospital, Bratislava.List of patients consists of 250 children (106 boys, 144 girls): X-ray images showing lumbo-sacral part of vertebral column were evaluated retrospectively (X-ray of native abdomen, urological tract or skeleton). Authors assessed presence or non-presence of spina bifida on images, without relation to age, gender or diagnosis of patients.From the total number of 250 radiograms, 72 findings were positive (36 boys and 36 girls), 160 images were negative, 18 were unsuitable for evaluation due to low image quality. The highest diagnostic capture was from urological images - 40% of all positive findings. Incidence of spina bifida in Children's Hospital concluded from X-ray images is quite high - 28.8%.According to the data from National Centre of Health Statistics the incidence of open caudal neural tube defects in Slovakia is under 5 per 10 000 live-born children at present time. However the occurrence of occult spina bifida is not known exactly. The high rate of spina bifida presented herein (28%) can be caused by relatively low number of evaluated radiograms. Also the fact that children were not only healthy ones and data were obtained from the western part of Slovakia as well. In conclusion we can say that after accidental finding of caudal neural tube defect consecutive diagnostics should be performed in clinical positive cases - genetics, MRI and consultation with specialists to decide for the optimal follow up of the patient.

"Conditio sine qua non" in the management of open neural tube defects includes closure of all layers with as minimum as possible tension left within the suture region, in order to prevent early, as well as long-term postoperative complications. In extensive fascial defects, the authors used the Gore-Tex patch as an alternative to myofascial or fasciocutaneous flaps.From January 2004 to January 2008, 23 patients suffering from open spina bifida underwent surgery in the Bratislava Pediatric Surgery Centre. In 17 subjects, the fascia was sutured following a myofascial release, in 2 subjects the suture was secured with tissue adhesive. In 4 subjects, the Gore-Tex patch was implanted to secure the "tension free" plasty; the Gore-Tex Dual Mesh was used in 2 subjects as well as the Gore-Tex Spinal.Two subjects, who had the Gore-Tex Dual Mesh implanted, developed sequestration of the implant during the late postopertive period. Upon reoperation, the authors removed the Gore-Tex Dual Mesh in the both subjects. However, they found a firm fibrous membrane, which was considered sufficient to protect the dural sac. On the contrary, the both subjects who had the Gore-Tex Spinal implanted, healed with no complications recorded.Based on the experience, the Gore-Tex Dual Mesh, although implanted lege artis, does not appear a suitable material for fascia replacements in open spina bifida plastic procedures. Further experience will give more evidence, whether Gore-Tex Spinal would be a suitable alternative, however, the courses in the 2 subjects have hitherto been encouraging.

Congenital diaphragmatic hernia (CDH) is usually diagnosed antenatally or through the neonatal period at present. It is also used to treat and manage CDH in this date. However in rare cases CDH could be presented after finished neonatal period with non-specific and misleading symptoms. The aim of our presentation is to analyze the patients with late - presenting and diagnosed CDH.During period 1996-2006 we operated on 54 children with CDH, 12 of them with late - presenting CDH, age variance was 9 months and 6 years. The spectrum of symptoms was from asymptomatic CDH (2 patients), mild respiratory (4 patients) and gastrointestinal symptoms (4 patients), combination of respiratory and gastrointestinal symptoms (2 patients) and finally the symptomatology of bowel incarceration (2 patients).Seven children presented with another associated malformations (m. Down, congenital heart failure, hydrocephalus, anorectal atresia). All 12 patients were operated on with a good results. The operation was composed of reposition of the herniated part of gastrointestinal tract (without need of resection) and diaphragmatic plastic. Two patients were reoperated on - once because of diaphragmatic relaxation and the second one due to consecutive heart operation.Congenital diaphragmatic hernia could be presented with chronic and non-specific respiratory or gastrointestinal symptoms. Time to time, presentation of diaphragmatic hernia as "acute abdomen" could be seen. The operation is indicated, also in asymptomatic patients as a prevention of life-threating events.

State with progressive development of intestinal obstruction may leads to the misinterpretation of acute gastroenteritis in infant period. After passing of newborn period the differential diagnosis is not easy. Loss of time which leads to the correct diagnosis is ufavourable for patient because of worsening of the condition. The authors present a case review of 5 months old girl in whom cystoid intestinal duplication caused complete ileo-coecal occlusion. Associated diagnosis in our patient were anus perinealis ventralis and diverticulum Meckeli. The treatment of enteral duplication and Meckel's diverticulum was done in one stage surgery.

Meckel's diverticulum (MD) is the most frequent anomaly of the small intestine, usually asymptotic. Complications of MD in children are usually bleeding and inflammation. Signs are non specific and diagnostics is prolonged. Scintigraphy is the method for the verification of bleeding from MD. A positive finding is the indication for exploration using laparoscopic or classic approach. In patients with bleeding of the MD, the literature presents, that there is usually gastric mucosa. The authors present patients with bleeding and the microscopic picture of the MD was intestinal mucosa with bleeding.

The authors analyze options for intestinal stoma procedures for congenital digestive tract malformations. A primary anastomosis is considered the principal procedure, however, the authors advice against its risky performance. Although a stoma being the ultimate treatment option, indications for stoma procedures should be considered carefully and the procedure should be performed on time, to avoid any potential later pathology development in the anastomosis. The authors compare and critically assess the following principal three types of the stoma procedures: 1. The modified Gross procedure; 2. The Bishop-Koop Roux Y anastomosis; 3. The Santulli-Blanc Roux Y anastomosis. The authors do not favour any of the above and they stress out that for each individual malformation, its own optimal procedure should be selected and performed.

Abdominoscrotal hydrocele is encountered rarely in child age. The authors present an account on two patients with abdominoscrotal hydrocele in a three- and fifteen-year-old boy. They discuss its development, draw attention to the not very marked clinical manifestations, diagnostic pitfalls and the contribution of sonography to diagnosis.

The authors investigated the effectiveness of ordering of blood for elective surgery. Analysis of a group of 333 operated patients revealed that blood was administered only in 9% of the operations, i.e when compared with the number ordered the ratio ordered: issued was 13:1. Based on their own experience the authors present the possibility how to improve the blood ordering system from the surgical as well as blood bank activity aspect.

Based on previous work of their own and data in the literature the authors outlined diagnostic and classification criteria of acute pancreatitis. The latter were applied in a prospective study. Thus a group of 71 patients with acute pancreatitis was obtained. In 10 patients of this group at the same time intervals and while the same therapeutic procedures were used, the serum protease levels were followed up. The authors assumed that it will be possible to express thus objectively the severity of the disease and to diagnose in time necrotizing forms of acute pancreatitis. The results re demonstrated the feasibility and suitability of this procedure only for assessment of the severity of the disease.
