Management of pediatric blunt abdominal trauma with split liver or spleen injuries: a retrospective study.

BACKGROUND: Blunt abdominal trauma is a prevailing cause of pediatric morbidity and mortality. It constitutes the most frequent type of pediatric injuries. Contrast-enhanced sonography (CEUS) and contrast-enhanced computed tomography (CECT) are considered pivotal diagnostic modalities in hemodynamically stable patients. AIM: To report the experience in management of pediatric split liver and spleen injuries using CEUS and CECT. PATIENTS AND METHODS: This study included 246 children who sustained blunt abdominal trauma, and admitted and treated at three tertiary hospitals in the period of 5 years. Primary resuscitation was offered to all children based on the advanced trauma and life support (ATLS) protocol. A special algorithm for decision-making was followed. It incorporated the FAST, baseline ultrasound (US), CEUS, and CECT. Patients were treated according to the imaging findings and hemodynamic stability. RESULTS: All 246 children who sustained a blunt abdominal were studied. Patients' age was 10.5 ± 2.1. Road traffic accidents were the most common cause of trauma; 155 patients (63%). CECT showed the extent of injury in 153 patients' spleen (62%) and 78 patients' liver (32%), while the remaining 15 (6%) patients had both injuries. CEUS detected 142 (57.7%) spleen injury, and 67 (27.2%) liver injury. CONCLUSIONS: CEUS may be a useful diagnostic tool among hemodynamically stable children who sustained low-to-moderate energy isolated blunt abdominal trauma. It may be also helpful for further evaluation of uncertain CECT findings and follow-up of conservatively managed traumatic injuries.

Laparoscopy as a Primary Investigatory Tool in Pediatric Abdominal Masses.

BACKGROUND: Management of abdominal masses still pose a major challenge for pediatrician and surgeons with many controversy as regards the best investigatory tools. AIM OF THE WORK: This study was designated to evaluate the role of diagnostic laparoscopy in investigating equivocal pediatric masses that had undergone other imaging modalities. PATIENTS AND METHODS: A combined prospective and retrospective multicenter study over a period of 12 years from January 2005 to December 2016 was undertaken. This study included all children aged from 3 months to 15 years. Those having a documented diagnosis through other imaging modalities such as sonographic and/or computed tomography (CT) guided biopsy were excluded. All patients underwent multiport diagnostic laparoscopy for biopsy of the mass. All specimens were histologically assessed basically using Hematoxylin and Eosin (H and E) staining; some specimens had been immunohistochemically studied. RESULTS: One hundred and thirty-two patients were recruited in the study. They were 69 males and 63 females with a male to female ratio of1.1:1. The age ranged from 3 months up to 15 years with the mean age of 2.7 ± 0.8 years. Out of the total studied group, 54 patients were diagnosed with neuroblastoma (40.9%), while 66 (50%) were having nephroblastoma. The remaining 12 (9.1%) were having non-Hodgkin's abdominal lymphoma. Not all patients showed any complication related to the procedure. The mean follow up period was 3.6 years. Most of the cases (n=121) despite having a different diagnosis, were clinically staged as grade I to grade II (91.7%). Neither intraoperative nor postoperative complications were recorded during this technique. The mean operative time was 72 mins ± 20 in the earliest group; yet, it has declined to be 32 ± 12 minutes in the latest group due to the advancement of the learning curve. CONCLUSION: Laparoscopy is accurate and safe for investigating pediatric solid abdominal masses. It should be used as the sole tool for biopsy of solid abdominal tumors in pediatrics.

Initial Surgery in Tailoring Treatment for Children With Stage II and III Wilms' Tumor: An Experience From Resource Challenged Settings.

BACKGROUND: Although Wilms' tumor (WT) is ranked first among primary childhood's renal neoplasm, controversy still exists regarding the best approach for its management. The study aimed at evaluating the role of initial surgery in treatment of stage II and III pediatric WT as a part of the short administration schedule as in National Wilms' Tumor Study (NWTS)-4 and evaluating its effectiveness compared to the long administration schedule. METHODS: The study included 30 children who were primarily diagnosed as stage II and III WT. They were divided into two equal groups. Group I (n = 15) included those children who had undergone neoadjuvant chemotherapy followed by surgery and postoperative chemotherapy, while group II (n = 15) included those children who had undergone primary surgery as an initial management followed by chemotherapy. After a mean postoperative follow-up period of 14 ± 5 months, clinical and radiological evaluation was performed to all patients. RESULTS: In group I, 10 patients were preoperatively diagnosed as stage II and five patients as stage III while in group II, 11 patients were proved to be stage II and four patients were stage III. After a follow-up period, clinical and radiological evaluation using CT was performed to all patients. In patients with stage II, evidence of recurrence was noted in three patients of group I whereas no patient showed any evidence of recurrence in group II. In patients with stage III, rebound increase in size was seen in two patients in group I and only one patient in group II. CONCLUSIONS: Initial surgical intervention with appropriate adjuvant therapy has better outcomes than the neoadjuvant chemotherapy and delayed surgery for children primarily diagnosed as stage II and III WT. Moreover, it may act as a short administration schedule for the treatment as it is not less effective than the long administration schedule and can be administered at a substantially lower total treatment cost.
