Aim The aim of the study is to present views of pediatric surgeons on the optimal approach to inguinal hernias in children. Methods A questionnaire was submitted to participants of EUPSA-BAPS 2012 and it was returned by 187 responders (85% senior surgeons) from 46 (27 European) countries. Main Results Approximately 80% of the responders work in centers treating more than 100 cases/year. Approximately 79% of the responders routinely perform laparoscopy for other conditions, but of these, only 22% of the responders routinely perform laparoscopic inguinal hernia repair. Open approach is preferred by 83% of the responders. Of these, 79% of the responders favor unilateral approach, 12% of the responders contralateral, and 9% of the responders contralateral laparoscopic exploration via hernial sac. Considered advantages are the less risk of recurrence (66%), less abdominal organ injury (31%), less vas/vessel injury (25%), and speed (16%). Laparoscopic approach is preferred by 17% of the respondents, of whom 58% perform laparoscopy at all ages, 15% only in younger than 1-year-old infants. Approximately 81% of the responders offer laparoscopy to both sexes, and 17% only in girls. Only 15% would do laparoscopy after incarceration. Purse string is the most popular (58%), then laparoscopic-guided percutaneous closure (28%), flip-flap (6%), or other techniques (8%). Proficiency is achieved after 50 (14%), 25 (48%), 10 (32%), or 5 (6%) laparoscopic hernia repairs. Considered advantages are less metachronous contralateral hernias (57%), better cosmesis (41%), easier technique (34%), less vas/vessel injury (31%), and less postoperative pain (22%). A total of 50 responders are planning to start laparoscopic hernia repairs. Conclusions Most pediatric surgeons favor open unilateral inguinal hernia repair. The role of laparoscopy in inguinal hernias is still controversial and yet to be accepted even amongst pediatric surgeons expert in laparoscopy. © 2014 Georg Thieme Verlag KG Stuttgart New York.

Background: A novel self-expanding drug-eluting stent was designed to release everolimus 225 μg/cm2 to prevent restenosis following peripheral arterial intervention. The purpose of this study was to measure the pharmacokinetic profile of everolimus following stent implantation. Methods: One hundred four patients with symptomatic peripheral arterial disease underwent implantation of everolimus-eluting stents in the femoropopliteal arteries. In a prespecified subset of 26 patients, blood samples for assay of everolimus content were collected prior to stent implantation, at 1, 4, and 8 hours postprocedure, prior to discharge, and at 1 month postprocedure. Results: A total of 39 stents, ranging from 28 mm to 100 mm in length, were implanted in 26 patients, resulting in a total delivered everolimus dose range of 3.0 to 7.6 mg. Following the procedure, the maximum observed everolimus blood concentrations (Cmax) varied from 1.83 ± 0.05 ng/mL after implantation of a single 80-mm stent to 4.66 ± 1.78 ng/mL after implantation of two 100-mm stents. The mean time to peak concentration (T max) varied from 6.8 hours to 35 hours. The pharmacokinetics of everolimus were dose-proportional in that dose-normalized Cmax and area under the curve values were constant over the studied dose range. Conclusions: After implantation of everolimus-eluting self-expanding stents in the femoropopliteal arteries, systemic blood concentrations of everolimus are predictable and considerably lower than blood concentrations observed following safe oral administration of everolimus. © 2012 Society for Vascular Surgery.

Introduction Because many aspects of the management of esophageal atresia (EA) are still controversial, we evaluated the practice patterns of this condition across Europe. Methods A survey was completed by 178 delegates (from 45 [27 European] countries; 88% senior respondents) at the EUPSA-BAPS 2012. Results Approximately 66% of respondents work in centers where more than five EA repairs are performed per year. Preoperatively, 81% of respondents request an echocardiogram, and only 43% of respondents routinely perform preoperative bronchoscopy. Approximately 94% of respondents prefer an open approach, which is extrapleural in 71% of respondents. There were no differences in use of thoracoscopy between Europeans (10%) and non-Europeans (11%, p = nonsignificant). Approximately 60% of respondents measure the gap intraoperatively. A transanastomotic tube (90%) and chest drain (69%) are left in situ. Elective paralysis is adopted by 56% of respondents mainly for anastomosis tension (65%). About 72% of respondents routinely request a contrast study on postoperative day 7 (2-14). Approximately 54% of respondents use parenteral nutrition, 40% of respondents start transanastomotic feeds on postoperative day 1, and 89% of respondents start oral feeds after postoperative day 5. Pure EA: 46% of respondents work in centers that repair two or more than two pure EA a year. About 60% of respondents opt for delayed primary anastomosis at 3 months (1-12 months) with gastrostomy formation without esophagostomy. Anastomosis is achieved with open approach by 85% of respondents. About 47% of respondents attempt elongation of esophageal ends via Foker technique (43%) or with serial dilations with bougies (41%). Approximately 67% of respondents always attempt an anastomosis. Gastric interposition is the commonest esophageal substitution. Conclusion Many aspects of EA management are lacking consensus. Minimally invasive repair is still sporadic. We recommend establishment of an EA registry.

We present herein the proposal of the European Laryngological Society working committee on nomenclature for a systematic classification of open partial horizontal laryngectomies (OPHL). This is based on the cranio-caudal extent of laryngeal structures resected, instead of a number of different and heterogeneous variables present in existing nomenclatures, usually referring to eponyms, types of pexy, or inferior limit of resection. According to the proposed classification system, we have defined three types of OPHLs: Type I (formerly defined horizontal supraglottic laryngectomy), Type II (previously called supracricoid laryngectomy), and Type III (also named supratracheal laryngectomy). Use of suffixes "a" and "b" in Type II and III OPHLs reflects sparing or not of the suprahyoid epiglottis. Various extensions to one arytenoid, base of tongue, piriform sinus, and crico-arytenoid unit are indicated by abbreviations (ARY, BOT, PIR, and CAU, respectively). Our proposal is not intended to give a comprehensive algorithm of application of different OPHLs to specific clinical situations, but to serve as the basis for obtaining a common language among the head and neck surgical community. We therefore intend to present this classification system as a simple and intuitive teaching instrument, and a tool to be able to compare surgical series with each other and with non-surgical data. © 2014 Springer-Verlag.

Objective: To study the impact of periarterial papaverine application on the postoperative glomerular filtration rate (GFR) after retroperitoneoscopic partial nephrectomy (PN). Materials and methods: A consecutive series of patients underwent retroperitoneoscopic PN with intraoperative, periarterial application of 50 mg of papaverine. These patients were compared with a group of patients who underwent retroperitoneoscopic PN at this institution prior to this protocol. Patients were matched for preoperative GFR, tumor size, ischemia time, and operative time. Results: In total, 37 patients who received periarterial papaverine (P) and 37 patients without periarterial papaverine, who served as controls (C), were included in this analysis and matched according to preoperative GFR (P: 98.2, C: 97.8 ml/min/1.72 m2), tumor size (P: 2.5 cm, C: 2.5 cm), ischemia time (P: 22 min, C: 23 min), and operative time (P: 86 min, C: 85 min). Postoperative GFR was 86.4 ml/min/1.72 m2 in controls (C) and 91.8 ml/min/1.72 m2 in the papaverine group. The pre- to postoperative decrease in GFR was reduced by 56.9% in the papaverine group compared with controls (relative decrease in GFR: P: 5.3% vs. C: 12.5%; P = 0.02). Intra- and postoperative complications were pneumothorax (P: n = 2, C: n = 3), urinary fistula (P: n = 0, C: n = 2), and one suture-fixed drainage (P: n = 1, C: n = 0). No papaverine-related side effects were observed, and the surgical procedure was not hampered by the periarterial application of papaverine. Conclusion: As with laparoscopic donor nephrectomy, periarterial papaverine seems to improve postoperative renal function after retroperitoneoscopic partial nephrectomy. This nephroprotective effect might be particularly advantageous for patients with an impaired renal function preoperatively. © 2011 Springer-Verlag.
