Outcome of alimentary tract duplications operated on by minimally invasive surgery: a retrospective multicenter study by the GECI (Groupe d'Etude en Coeliochirurgie Infantile).

BACKGROUND: Alimentary tract duplications (ATD) are a rare cause of intestinal obstruction in childhood. There are many case reports but few series about laparoscopy or thoracoscopy for ATD. The aim of our study was to report the outcome of minimally invasive surgery (MIS) for ATD. METHODS: This was a retrospective multicenter study from the GECI (Groupe d\u27Etude en Coeliochirurgie Infantile). We reviewed the charts of 114 patients operated on by MIS for ATD from 1994 to 2009. RESULTS: Sixty-two patients (54 %) had a prenatal diagnosis. Forty-nine patients (43 %) were symptomatic before surgery: 33 of those patients (63 %) with postnatal diagnosis compared to 16 (25 %) with prenatal diagnosis (P < 0.01). In this last group, the median age at onset of symptoms was 16 days (range = 0-972). One hundred and two patients had laparoscopy (esophageal to rectal duplications) and 12 patients had thoracoscopy for esophageal duplications. The mean operative time was 90 min (range = 82-98). There were 32 (28 %) resection anastomoses, 55 (48 %) enucleations, and 27 (24 %) unroofings. The conversion rate was 32 %, and in a multivariate analysis, it was significantly higher, up to 41 % for patients weighing <10 kg (P < 0.01). Ten patients (8 %) had unintentional perioperative opening of the digestive tract during the dissection. Eight patients had nine postoperative complications, including six small bowel obstructions. The median length of hospital stay was 4 days (range = 1-21) without conversion and 6 days (range = 1-27) with conversion (P = 0.01). The median follow-up was 3 months (range = 1-120). Eighteen of the 27 patients who underwent partial surgery had an ultrasound examination during follow-up. Five (18 %) of them had macroscopic residue. CONCLUSION: This study showed that MIS for ATD is feasible with a low rate of complications. Patients with prenatal diagnosis should have prompt surgery to prevent symptoms, despite a high rate of conversion in small infants

Esophageal atresia: data from a national cohort

PURPOSE: A prospective national register was established in 2008 to record all new cases of live-birth newborns with esophageal atresia (EA). This epidemiological survey was recommended as part of a national rare diseases plan. METHODS: All 38 national centers treating EA participated by completing for each patient at first discharge a questionnaire validated by a national committee of experts. Data were centralized by the national reference center for esophageal anomalies. Quantitative and qualitative analyses were performed, with P-values of less than 0.05 considered statistically significant. Results of the 2008-2009 data collection are presented in this report. RESULTS: Three hundred seven new living cases of EA were recorded between January 1, 2008, and December 31, 2009. The male/female sex ratio was 1.3, and the live-birth prevalence of EA was 1.8 per 10,000 births. Major characteristics were comparable to those reported in the literature. Survival was 95%, and no correlation with caseload was noted. CONCLUSIONS: Epidemiologic surveys of congenital anomalies such as EA, which is a rare disease, provide valuable data for public health authorities and fulfill one important mission of reference centers. When compared with previous epidemiological data, this national population-based registry suggests that the incidence of EA remains stable

Le diagnostic anténatal modifie-t-il la prise en charge néonatale et le devenir à 1 an des enfants suivis pour atrésie de l’œsophage de type III ?

OBJECTIVE: Evaluate neonatal management and outcome of neonates with either a prenatal or a post-natal diagnosis of EA type III. STUDY DESIGN: Population-based study using data from the French National Register for EA from 2008 to 2010. We compared children with prenatal versus post-natal diagnosis in regards to prenatal, maternal and neonatal characteristics. We define a composite variable of morbidity (anastomotic esophageal leaks, recurrent fistula, stenosis) and mortality at 1 year. RESULTS: Four hundred and eight live births with EA type III were recorded with a prenatal diagnosis rate of 18.1%. Transfer after birth was lower in prenatal subset (32.4% versus 81.5%, P<0.001). Delay between birth and first intervention was not significantly different. Defect size (2cm vs 1.4cm, P<0.001), gastrostomy (21.6% versus 8.7%, P<0.001) and length in neonatal unit care were higher in prenatal subset (47.9 days versus 33.6 days, P<0.001). The composite variables were higher in prenatal diagnosis subset (38.7% vs 26.1%, P=0.044). CONCLUSION: Despite the excellent survival rate of EA, cases with antenatal detection have a higher morbidity related to the EA type (longer gap). Even if it does not modify neonatal management and 1-year outcome, prenatal diagnosis allows antenatal parental counseling and avoids post-natal transfer

Laparoscopic adrenalectomy in children: experience of the GECI in 16 cases

Background: Conventional adrenalectomy usually necessitates a large incision. In some cases, laparoscopic adrenalectomy offers a less aggressive solution to the patient's problem. Patients and Methods: Laparoscopic adrenalectomy for clearly defined lesions was performed in five girls and nine boys with a mean age of 9 years. The indication was incidental discovery in four patients, hypertension in six (two of whom had von Hippel Lindau syndrome), Cushing's disease in two, and gynecomastia or premature puberty in one patient each. The lesion was on the right side in five patients and the left side in six and was bilateral in three. The mean diameter was 35 mm. The urinary concentrations of vanillylmandelic acid and homomandelic acid were normal in five patients with neurogenic tumors and elevated in five patients with pheochromocytoma. An anterior transabdominal approach was used in nine patients and a lateral retroperitoneal approach in seven. Results: The operating time ranged from 35 to 320 minutes. There were three conversions to open surgery (20%). There were no perioperative or postoperative complications. Histologic examination revealed 13 benign lesions (7 pheochromocytomas, 3 ganglioneuromas, 2 cortical adenomas, and 1 hyperplasia), 1 malignant lesion (N-Myc-negative neuroblastoma, which was removed after conversion to open surgery), and two indeterminate lesions. Of the latter lesions, one was an N-Myc-negative gangioneuroblastoma, and the other was an adrenocortical tumor that was treated initially by local excision and 1 month later by total adrenalec via an open approach. There were no tumor remnants in the specimen. All patients are alive without evidence of recurrence with follow-up of 6 months to 4 years. Conclusions: The laparoscopic approach should be reserved for well-defined lesions <0.5 cm that are probably benign, although the nature of the lesion can be difficult to define preoperatively. The indications can be extended to stage I nonsecreting neuroblastoma in some situations and, for some surgeons, to tumors of stage IV or V. There seems to be no age or weight limit. A left-sided lesion usually is resected via a lateral retroperitoneal approach and a right-sided lesion by an anterior transperitoneal approach, but the details of the technique with the anatomy and the surgeon's experience. Oncologic principles must be respected, and the rate of conversion to open surgery is high

Prenatal diagnosis of bowel malposition using T2-weighted fetal MRI sequences

International audienceObjective: The goal of this study was to investigate the capability of T2-weighted magnetic resonance imaging (MRI) in revealing fetal bowel malposition. Materials and methods: All fetal MRI examinations (excluding central nervous system MRI examinations) performed in our department from January 2005 to January 2014 were retrospectively studied by 2 independent observers for situs, stomach and jejunum location on T2-weighted images. Patients data were also reviewed for results of ultrasound examinations, MRI indication, and gestational age. Abnormally positioned jejunums were classified into 3 groups: intrathoracic (A), extra-fetal (B) and abnormal intra-fetal (C). Prenatal data were compared to postnatal imaging, surgery or autopsy findings that served as standard of reference. Results: A total of 709 fetal MRI examinations were analyzed. In 64 fetus (9%), the jejunum was not present in the left subgastric area on T2-weighted MR images. In these 64 fetuses, proximal jejunum was intrathoracic (41/64, 64%, group A), extra-fetal (11/64, 17%, group B), or intra-abdominal but abnormally positioned (12/64, 19%, group C). Interobserver agreement was 100%. All diagnoses for fetuses in groups A and B (52 cases) were confirmed postnatally (41 cases) or at autopsy (11 cases). In group C, bowel malposition was suspected after ultrasound in only 2/12 fetuses (16.6%); it was confirmed postnatally in 1 fetus but not confirmed in the remaining one. In the 10 remaining fetuses (83%), malposition was confirmed postnatally although not initially suspected. Conclusion: T2-weighted fetal MR images are useful for the prenatal diagnosis of bowel malposition, even when they are unsuspected on ultrasound examination.

Work-related upper limb musculoskeletal disorders in paediatric laparoscopic surgery. A multicenter survey.

BACKGROUND: Surgeons are at risk for developing work-related musculoskeletal symptoms (WMS). The present study aims to examine the physical factors and their association with WMS among pediatric laparoscopic surgeons. METHODS: A questionnaire consisting of 21 questions was created and mailed to 25 pediatric laparoscopic surgeons (LG). 23/25 surgeons (92%) completed the survey. The questionnaire was analyzed and then split into 2 groups. Group 1 (LG1) included surgeons with greater laparoscopic experience, and group 2 (LG2) included surgeons with less important laparoscopic experience. In addition, we constructed and sent to the same surgeons a similar questionnaire focused on WMS after an open procedure (OG) with the aim to compare results of LG with OG. RESULTS: The prevalence rate of WMS with shoulder symptoms was 78.2% in surgeons that performed laparoscopy for more than 10years, with 60.8% also reporting other pain. In 66.6% this pain is evident only after a long-lasting procedure. Forty-four percent of these surgeons require painkillers at least twice a week. Fifty percent of these surgeons also suffer at home. Fifty-five and one half percent of surgeons indicate that this pain is related to their laparoscopic activity. Forty-three and a half percent think that laparoscopy is beneficial only for the patient but has a bad ergonomic effect for surgeons. Sixty-five and two-tenths percent think that robotic surgery can be helpful to improve ergonomics. Comparing the groups, WMS occur more frequently in LG (78.2%) than in OG (56.5%), but this difference was not statistically significant (χ(2)=0.05). In addition, WMS occur more frequently in LG1 (84.6%) than in LG2 (70%), but this difference was not statistically significant (χ(2)=0.05). CONCLUSIONS: These results confirmed a strong association between WMS and the number of laparoscopic procedures performed. Skilled laparoscopic surgeons have more pain than less skilled laparoscopic surgeons. WMS in the same group of surgeons are more frequent after laparoscopy than after open procedures. The majority of surgeons refer to shoulder symptoms
