Laparoscopic inguinal hernia repair in children via PIRS (percutaneous internal ring suturing).

INTRODUCTION: The miniinvasive approach is a trend in pediatric surgery nowadays. The new surgical technique called percutaneous internal ring suturing (PIRS) is a promising method bringing all the benefits of miniinvasive surgery. METHODS: Prospective study of patients operated on using the PIRS technique from 01 January 2018 to 01 January 2020 at the Department of Pediatric Surgery, 2nd Faculty of Medicine, Charles University, University Hospital Motol. RESULTS: 73 patients (25 boys and 48 girls) were operated on using PIRS. The median age was 68 months. 90 % of operations were performed by the same team of surgeons. During the procedure there were found 53 right-sided and 38 left-sided inguinal hernias. In 18 cases the hernia was bilateral, but only in 13 cases was this diagnosis made before the operation. A non-absorbable stitch was used in 57 cases to close the internal ring of the inguinal canal, and a non-absorbable monofilament in 16. The median operating time was 34 minutes. There were 3 recurrences (3.3 %) in our study.  Conclusion: In our initial study, the PIRS technique proved to be a safe alternative method to the open inguinal hernia surgery. This method provides the benefit of allowing to revise the contralateral inguinal canal as a prevention of a metachronous inguinal hernia. The cosmetic results were excellent.

Extraperitoneal pocket splenopexy is a suitable solution for wandering spleen in children and adolescents - case report.

INTRODUCTION: Wandering spleen is a rare cause of recurrent abdominal pain in children that is difficult to diagnose. Splenopexy should be preferred to splenectomy. CASE REPORT: The patient, a 4 years old girl on growth hormone therapy, was referred to the Department of Paediatric Surgery for an assessment of episodes of abdominal colic and frequent vomiting. Sonography did not indicate any pathology, gastrointestinal contrast study showed an altered shape of the gastric outlet, and upper endoscopy diagnosed a prepyloric membrane. Open surgery was indicated based on these examinations, revealing a large wandering spleen and dilated stomach and small bowel loops oppressed by the long splenic suspensory ligaments. Pyloroplasty was performed with the antral membrane excision and shortening of the long gastrosplenic ligament and placement of the spleen into the left hypochondrium. No complications occurred in the postoperative period. Four months later the patient was hospitalised again for abdominal colic pain. Surgical revision of the abdomen revealed the wandering spleen in the mesogastrium. Even though the spleen was the cause of the second surgery, we decided to preserve the spleen. Partial splenectomy was done, fixing the large spleen into an extraperitoneal pocket in the left hypochondrium. The postoperative course was uneventful. Blood flow to the spleen is regularly monitored by Doppler ultrasound. Vaccination was indicated at the office of haematology according to the scheme for splenectomy patients; however, prophylactic antibiotic therapy was not needed given the good function of the preserved part of the spleen. CONCLUSION: Extraperitoneal fixation of the spleen seems to be a good choice for patients with a wandering spleen, particularly for children and adolescents.

[Prediction of bowel damage in patients with gastroschisis]. / Predikce poskození streva u pacientu s gastroschízou.

INTRODUCTION: Gastroschisis is the most common malformation among abdominal wall defects with the incidence of 1:45000 live birth neonates. Postoperative care for these patients is very difficult due to the risk of abdominal compartment syndrome. The identification of markers that correlate with bowel damage in gastroschisis may prevent this serious postoperative complication. METHODS: Review of the literature. CONCLUSION: Prenatal ultrasound prediction of bowel damage followed by an appropriate surgical strategy is a possibility of optimizing care and outcomes in gastroschisis patients. The dynamics of I-FABP is a promising biomarker for the elimination of abdominal compartment syndrome during postoperative care.Key words: gastroschisis preformed silo intraabdominal dilatation I-FABP.

[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.

[Chest injuries in polytraumatized children]. / Poranení hrudníku u detí s polytraumatem.

Chest injuries in children are part of polytrauma resulting from high-energy violence, most often caused by traffic accidents. Blunt chest injuries (95%) are significantly more frequent than penetrating injuries (5%). Lung contusion, rib fracture, pneumothorax or haemothorax, are the more common injuries, but tracheobronchial rupture, cardiac or diaphragmatic injuries may also occur. The anterior X-ray image remains the basic examination method for isolated chest injuries. CT trauma scan with a contrast medium is done in polytraumatized children. Blunt injuries of intra-thoracic organs in haemodynamically stable children are treated mostly conservatively (85%) under full monitoring at the ICU. Surgical treatment is necessary in a minority of patients. Mortality and morbidity of patients with chest injury depend on the actual combination of multiple body systems injury. The severity of total injury can be predicted using objective scoring systems (Abbreviated Injury Scale=AIS; Injury Severity Score=ISS). Overall mortality ranges from 6 to 20%. Mortality is high but this is mainly due to associated head injuries.Key words: multiple trauma thoracic trauma - paediatric lung contusion Injury Severity Score=ISS.
