Compressive chylothorax after lumbar spine fracture.

A 14-year-old boy was admitted to the hospital after an episode of blunt trauma to the thorax, resulting in a Chance fracture of L1 and a compressive chylothorax 72h after admission. After initial drainage in the operating room, conservative management was successful. This case study documents one of the rare complications of spinal fractures in the context of high-energy blunt trauma. It is the first detailing a noniatrogenic post-traumatic compressive chylothorax in pediatrics responding positively to conservative management. Drainage should be considered the first-line procedure for both therapeutic and diagnostic purposes. Surgery is required if the leakage is still present after parenteral feeding and the implementation of a fat-free diet for 5-7 days.

Fetal median sacral artery anatomy study by micro-CT imaging.

PURPOSE: The median sacral artery (MSA) is the termination of the dorsal aorta, which undergoes a complex regression and remodeling process during embryo and fetal development. The MSA contributes to the pelvic vascularization and may be injured during pelvic surgery. The embryological steps of MSA development, anastomosis formation and anatomical variations are linked, but not fully understood. METHODS: The pelvic vascularization and more precisely the MSA of a human fetus at 22 weeks of gestation (GW) were studied using micro-CT imaging. Image treatment included arterial segmentations and 3D visualization. RESULTS: At 22 GW, the MSA was a well-developed straight artery in front of the sacrum and was longer than the abdominal aorta. Anastomoses between the MSA and the internal pudendal arteries and the superior rectal artery were detected. No evidence was found for the existence of a coccygeal glomus with arteriovenous anastomosis. CONCLUSIONS: Micro-CT imaging and 3D visualization helped us understand the MSA central role in pelvic vascularization through the ilio-aortic anastomotic system. It is essential to know this anastomotic network to treat pathological conditions, such as sacrococcygeal teratomas and parasitic ischiopagus twins (for instance, fetus in fetu and twin-reversed arterial perfusion sequence).

Laparoscopic pyloromyotomy for hypertrophic pyloric stenosis: a survey of 407 children.

INTRODUCTION: Pyloromyotomy is the standard care for hypertrophic pyloric stenosis. The traditional approach for this procedure is a right upper quadrant transverse incision, although other "open" approaches, such as circumumbilical or periumbilical incision have been described. The more recent approach used is laparoscopic pyloromyotomy (LP), but experience feedback is still debated and its benefits remain unproven. The aim of this study was to make a review of all our LP procedures with an objective evaluation according to the literature. METHODS: A retrospective analysis of all the LPs performed in one University Children's Hospital between 1 January 1996, and 30 December 2015 was realized. Information regarding the patient's status, intraoperative and postoperative data was analyzed. RESULTS: 407 patients were included in this study. The mean operative time of the overall procedure was 24 ± 13 min, which significantly increased with the length of the pyloric muscle (p = 0.004) and significantly impacted the full feeding time (p = 0.006). 3.4% required conversion to an open procedure during the LP. We observed a significant correlation between conversion for mucosal perforation and weight loss (p = 0.04) and between conversion for mucosal perforation and preoperative weight (p = 0.002). A redo procedure was indicated in 3.7%, for incomplete pyloromyotomy each time. The mean postoperative hospital length of stay for all procedures was 1.6 ± 0.8 days. There were no inflammatory scars. None had incisional hernias or wound dehiscence. DISCUSSION: LP procedure appeared to be as quick as the open procedure. Our results were similar to others series for intraoperative complications. According to operative time, this technique does not have an impact on operative room utilization. Vomiting duration at presentation in HPS does not seem to have a significant impact on postoperative outcomes. LP procedure causes little pain during the postoperative period. No wound complications were registered.

Robotic-assisted laparoscopic surgery for pediatric tumors: a bicenter experience.

Mini-invasive surgery is more and more integrated in pediatric surgery. The robotic-assisted surgery brought new advantages from which the patient and the surgeon could benefit compared to laparoscopy. Its use in oncological surgery is still controversial. 12 robotic-assisted tumor resections with the da Vinci Surgical Robot (Intuitive Surgical, Sunnyvale, CA) were attempted in 11 children (mean age 7.65 years; age range 0.75-16.75 years; mean weight 30.3 kg; weight range 8.6-62 kg) in two centers. Mean total operative time was 145 min (range 72-263 min). 1 procedure (8.3%) was converted. The pathology included renal tumors (n = 2; one nephroblastoma, one metanephric adenoma), adrenal tumors (n = 9; three neuroblastomas, two pheochromocytomas, two adrenocortical adenomas, one cystic lymphangioma, one paraganglioma) and a pancreatic tumor (n = 1; one pancreatic cyst). 4 tumors (33.3%) were malignant. Every patient underwent a R0 resection. 1 child (8.3%) developed a post operative complication. Mean length of hospitalization was 3.0 days (range 2-5 days). Followup averaged 3.3 years with no recurrence. All children are alive. Robot-assisted MIS seems to be safe and feasible in pediatric tumors. The oncological surgical principles were respected in our series with low morbi/mortality and good long-term results. Robotic surgery and its technical advantages bring potential benefits for children with cancer. It has a role to play in pediatric oncological surgery but its place and indications still need to be better defined.

The position of a written document in preoperative information for pediatric surgery: A randomized controlled trial on parental anxiety, knowledge, and satisfaction.

INTRODUCTION: Preoperative information is a legal and ethical obligation. Very little studies have evaluated the preoperative information method in pediatrics. Having a child operated on is stressful for the parents. Improving information is a way to lower their anxiety. Our study aims to measure the impact of a leaflet, which supports spoken information on parental anxiety, the comprehension-memorization of the information and their satisfaction. MATERIALS & METHODS: Prospective study including 178 patients of outpatient surgery, randomized in two groups: spoken information versus spoken information supported by a leaflet, which is then handed out to the parents. The messages were identical: physiopathology, risks without treatment, surgical technique and its possible complications, description of the hospitalization day, and postoperative care. Parental evaluation was made with self-questionnaires after the preoperative consultation, then on the day of surgery. At each moment we evaluated the level of anxiety, satisfaction of information quality and the comprehension-memorization of the data. RESULTS: Written information significantly improves the scores of comprehension-memorization, parental satisfaction and significantly decreases the level of anxiety. CONCLUSION: Significant impact of the written document as communication support in pediatric surgery, validating the method and encouraging it to be generalized to other pediatric surgery acts. LEVEL OF EVIDENCE: Level I. TYPE OF STUDY: Prognosis study.

[Impact of a written document for preoperative information on the use of Internet by parents]. / Impact d'un fascicule d'information préopératoire sur l'utilisation d'Internet par les parents.

INTRODUCTION: Preoperative information is a legal and ethical obligation. Very few studies have evaluated the preoperative information method in pediatrics. Having a child operated on is stressful for parents. The use of Internet to look for data on the pathology and its treatment is frequent, but often unprofitable and sometimes even harmful. This study aimed to measure the impact of a leaflet, which supports spoken information in preoperative consultation, on parents' use of the Internet before surgery. MATERIAL AND METHODS: Prospective study including 178 patients of outpatient surgery, randomized into two groups: spoken information alone versus spoken information supported by a personalized leaflet, which is then handed out to the parents. The messages were identical: physiopathology, risks without treatment, surgical technique, possible complications, description of the hospitalization day, and postoperative care. Parental evaluation was carried out with self-administered questionnaires after the preoperative consultation, then on the day of surgery. At each moment the rate of Internet use, its reasons, and the benefits were evaluated. RESULTS: The written document significantly reduced the use of the Internet by parents regardless of the child's age, their degree of anxiety, their level of understanding, and the time between consultation and the intervention. CONCLUSION: This study confirms the significant impact of the leaflet as a communication tool in pediatric surgery and the substantial utility for parents. This encourages us to generalize this method to other pediatric surgery acts.
