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.

[Tissue expansion in children: Indications and management of complications. A 10-year experience]. / L'expansion cutanée chez l'enfant : indications et gestion des complications. Notre expérience sur 10 ans.

INTRODUCTION: Tissue expansion is a plastic surgery technique which enables optimal quality and skin surface reconstruction in case of soft tissue defect. Despite the good results obtained, both from a functional and aesthetic point of view, there is a high rate of complications whose management seems to be essential to ensure satisfactory results. PATIENTS AND METHODS: We retrospectively reviewed the medical files of 45 children treated in our department between 2002 and 2012: 73 expanders were placed during 51 protocols. RESULTS: The studied protocols gathered a large variety of situations. Varied pathologies were treated: burn sequelae (39 %), giant congenital naevus (GCN) (27 %), scars (20 %), hamartoms (8 %), cutis aplasia (6 %), as well as diverse sites: scalp (45 %), trunk (35 %), head and neck (8 %), lower extremity (8 %), upper extremity (4 %). Complications occurred in 17 protocols representing 26 % of total expanders. GCN is a pathology with a significantly lower complication rate (P=0.013) whereas trunk is an anatomical location with a significantly higher complication rate (P=0.026). Overall, 84 % of reconstructions were evaluated as having a good result. This rate reached 76 % for complicated protocols. CONCLUSION: Tissue expansion in paediatric patients remains an efficient therapy in order to achieve a satisfactory reconstruction. Despite a high complication rate, good results can be obtained even in those complicated cases as long as they are well managed and anticipated. We also think that specific paediatric material would help to reduce supervention of some complications.

[Tissue expansion in management of giant omphalocele parietal sequelae]. / Place de l'expansion cutanée dans le traitement des séquelles pariétales des omphalocèles géantes.

OBJECTIVE: According to major difficulty for the giant omphalocele management in the visceral reintegration and the parietal closure, many teams use currently conservative treatment by topical application. These techniques are suppliers of a covered eventration and a scar sequela requiring a complementary treatment. We report the place of the tissue expansion as complementary treatment. PATIENTS AND METHODS: Two patients with a giant omphalocele benefited from a protocol of cutaneous expansion for the correction of their abdominal scar±of their residual eventration. RESULTS: An eventration closure was possible thanks to this protocol. The skin expansion allowed the complete excision of the abdominal scar and the defect cover. An additional skin graft was necessary in the first case. CONCLUSION: The cutaneous expansion in the parietal sequela management of the giant omphaloceles seems to be an interesting alternative. This technique should be realized remotely and except any septic context.

Weight-for-height Z-score improves in half of undernourished children hospitalized in surgical wards.

BACKGROUND: Overall, 10-15% of hospitalized children are undernourished. The present study focuses on pediatric surgical wards. We assessed the impact of undernutrition upon admission on the weight-for-height Z-score (Z-WFH) during hospitalization for surgery. Secondary aims were to investigate the influence of associated factors and to report on the use of nutritional support. METHODS: All children hospitalized for a surgical procedure between July 2015 and March 2016 were included in this monocentric, prospective study. Children were divided into two groups: whether the Z-WFH upon admission was below -2 standard deviations (undernourished) or not (not undernourished). RESULTS: A total of 161 of 278 eligible children were included; 27 were undernourished (17%). The change in Z-WFH during hospitalization was greater in undernourished children (0.31±0.11 vs. -0.05±0.05, P=0.005). Of undernourished children, 49% recovered a Z-WFH above -2 SD during hospitalization. There was no difference between undernourished children and not undernourished children regarding age, length of hospital stay, pre- and post-operative duration of nil per os, duration of surgical procedure, ASA score, emergency level of the surgical procedure, and enteral/parenteral nutrition. CONCLUSION: Our data suggest that the Z-WFH of undernourished children upon admission improved during hospitalization.

Hormonal receptors in cutaneous vascular malformations: 51 cases.

Vascular malformations (VMs) are rare congenital anomalies that develop during embryogenesis in different types of vessels. Several triggering factors of cutaneous VMs include trauma, infections, or hormonal changes. We investigated the expression of hormonal receptors (androgen, estrogen, progesterone) in tissue samples of well-characterized VMs. A secondary objective was to identify self-reported triggering factors for these VMs, including hormonal changes, in the cohort of patients. We included patients with VM samples obtained in the tertiary center for vascular anomalies of the University Hospital Center of Tours, France, from January 1, 2007, to August 1, 2018. Immunohistochemistry was used to detect the expression of hormonal receptors (estrogen, progesterone, androgens). We obtained 51 samples from 51 patients: 13 cystic lymphatic malformations (CLMs), 16 venous malformations (VeMs), 11 arteriovenous malformations (AVMs), 4 combined VMs, 4 PIK3CA-related overgrowth spectrum, 1 Parkes-Weber syndrome, 1 Gorham syndrome, and 1 multiple lymphangioendotheliomatosis with thrombopenia. In total, 38 (74.5%) samples were positive for androgen receptor: 11 (84.6%) CLMs, 12 (75.0%) VeMs, 8 (72.2%) AVMs, and 7/11 (63.5%) other samples. All samples were negative for estrogen and progesterone receptors. Triggering factors were self-reported in 7 cases and were most frequently hormonal changes (n = 6, 18.2%). Hormonal triggers were frequent in AVMs (n = 4). Among patients with identified hormonal triggers, VM samples were positive for androgen receptor in 3 and negative in 3. Three-quarters of our VM samples expressed androgen receptor, and most CLM, VeM, and AVM samples were positive. Hormonal triggers were identified in 6/33 patients, mostly with AVMs.

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.

[Infantile fibrosarcoma mimicking rapidly involuting congenital haemangioma (RICH)]. / Fibrosarcome infantile simulant un hémangiome type rapidly involuting congenital hemangioma (RICH).

BACKGROUND: While haemangioma is common, an unusual appearance or course should alert the clinician's concern. Congenital haemangioma, particularly rapidly involuting congenital haemangioma (RICH), may carry a risk of misdiagnosis as congenital malignant tumours such as infantile fibrosarcoma (also known as congenital infantile fibrosarcoma). In this case, histological diagnosis may prove inconclusive, as in the case reported herein. PATIENTS AND METHODS: At birth, a newborn baby presented angiomatous lesions on the sole of the left foot that was initially considered as congenital haemangioma. Histopathological examination suggested highly remodelled immature infantile haemangioma. After surgery, the tumour increased in size within eight weeks. Reanalysis of the histology slides resulted in a diagnosis of infantile fibrosarcoma. This diagnosis was confirmed by the presence of a specific translocation seen in infantile fibrosarcoma (ETV6/NTRK3). CONCLUSION: There is a risk of erroneous diagnosis in newborn infants between angiomatous tumour in RICH and malignant congenital tumours (particularly infantile fibrosarcoma). Clinicians should be attentive for this type of lesion and take all necessary diagnostic measures.

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.

Recessive dystrophic epidermolysis bullosa--management of hand deformities.

Scarring in recessive epidermolysis bullosa results in disability through hand deformities. Surgical treatment is complicated by technical and anaesthesiological problems due to the fragility of the skin and mucosa. In its dystrophic form epidermolysis bullosa leads to pseudosyndactyly and finger and palm contracture resulting in a "closed hand". Surgical treatment consists of resecting the contractures and opening the inter-digit webs, the uncovered areas healing under a close tulle gras dressing. Our technique differs from techniques which have already been reported. The dressing is changed only once a week, reducing the number of anaesthetics and allowing the child to attend our Day Hospital. Healing is complete within five weeks. Prevention of recurrence avoids the necessity of further surgery before five years of age. Post-operative open-hand splinting is well tolerated, delaying further contracture. Surgery is undertaken sometimes under general anaesthesia but more often under regional anaesthesia. We report the results of our experience.

[Epiphyseal separations of the knee]. / Les décollements épiphysaires du genou.

Basic principles of treatment of distal femoral and proximal tibial growth plate injuries are described in relation to the anatomical lesions using the Salter-Harris classification. Some strategic recommendations are made for complex fractures: the articular surface must first be reconstructed followed by the metaphysis if possible.

[Epithelioma of the medial canthus. Retrospective study of 47 surgically treated cases]. / Epithéliomas de l'angle interne de l'oeil. Etude rétrospective de 47 cas opérés.

The authors report a retrospective study of 47 cases of carcinoma of the medial canthal area which were operated on between 1982 and 1987. Patient age and the histological frequency of basal cell carcinoma were similar to those of studies previously reported. Local extension must be evaluated at the initial clinical examination and computed tomography can be very useful. Frozen section for histopathologic study should be done if there is the least doubt. The surgical treatment and different methods of local reconstruction are discussed.

[Inner canthus--anatomical junction. A surgical entity]. / Le canthus interne--carrefour anatomique. Entité chirurgicale.

The medial canthus is a surgical entity. The anatomical features are defined from a dissection of eight orbital regions. The pathways of carcinological invasion and the anatomical barriers are considered. The conclusions are discussed in the light of the data reported in the literature.

[Efficacy and tolerance of Algosteril (calcium alginate) versus Jelonet (paraffin gauze) in the treatment of scalp graft donor sites in children. Results of a randomized study]. / Evaluation de l'efficacité et de la tolérance d'Algostéril (compresse d'alginate de calcium) versus Jelonet (gaze paraffinée) dans le traitement du site donneur de greffe dermo-épidermique du cuir chevelu. Résultats d'un essai pédiatrique.

Split skin graft is frequently needed in the treatment of burned patients. Scalp is often free of burns. Due to its good skin quality and important surface, scalp is a very interesting skin donor site, specially in case of children. A controlled, randomised clinical trial was carried out in 10 French Plastic Surgery or Burns Units. It assessed the efficacy and the acceptability of calcium alginate dressing (Algosteril) versus paraffin gauze dressing (Jelonet) in the treatment of scalp donor sites in children. 67 children (mean age 54 months) entered the study, 34 in the alginate group and 33 in the control group. Follow-up visits were on day 2/d3, d5/d6, Day complete healing, d30 and d60 after surgery. The two groups were comparable on inclusion (demographic characteristics, burn nature and surface, donor site surface and thickness of split skin graft). The mean healing time was 10 and 11 days for Algosteril and Jelonet group respectively (ns). The quality of the newly formed tissue was estimated to permit a sooner skin reharvesting in the Algosteril group than in the control group (p = 0.003). Bleeding through dressing was significantly less important in the Algosteril group (p = 0.02). Changes were considered by investigators less painful with Algosteril on day complete healing (p = 0.0096). Hair growth is homogenous in both groups on day 30 and day 60 (ns). These results showed that scalp is a very interesting skin donor site and that Algosteril is of a real interest in donor site treatment.
