Abstract
The survival rate of children with esophageal atresia has today reached 95%. However, children are at risk of chronic morbidity related to esophageal and respiratory dysfunction, and associated anomalies. This study describes the pilot testing of a condition-specific health-related quality-of-life instrument for children with esophageal atresia in Sweden and Germany, using a patient-derived development approach consistent with international guidelines. Following a literature review, standardized focus groups were conducted with 30 Swedish families of children with esophageal atresia aged 2-17 years. The results were used for item generation of two age-specific pilot questionnaire versions. These were then translated from Swedish into German with considerations of linguistic and semantical perspectives. The 30-item pilot questionnaire for children aged 2-7 years was completed by 34 families (parent report), and the 50-item pilot questionnaire for children aged 8-17 years was completed by 52 families (51 child report, 52 parent report), with an overall response rate of 96% in the total sample. Based on predefined psychometric criteria, poorly performing items were removed, resulting in an 18-item version with three domains (Eating, Physical health and treatment, Social isolation and stress,) for children aged 2-7 years and a 26-item version with four domains (Eating, Social relationships, Body perception, and Health and well-being) for children aged 8-17 years. Both versions demonstrated good internal consistency reliability and acceptable convergent and known-groups validity for the total scores. The study identified specific health-related quality-of-life domains for pediatric patients with esophageal atresia, highlighting issues that are important for follow-up care. After field testing in a larger patient sample, this instrument can be used to enhance the evaluation of pediatric surgical care.

Abstract
Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) and anorectal malformations (ARM) represent the severe ends of the fore- and hindgut malformation spectra. Previous research suggests that environmental factors are implicated in their etiology. These risk factors might indicate the influence of specific etiological mechanisms on distinct developmental processes (e.g. fore- vs. hindgut malformation). The present study compared environmental factors in patients with isolated EA/TEF, isolated ARM, and the combined phenotype during the periconceptional period and the first trimester of pregnancy in order to investigate the hypothesis that fore- and hindgut malformations involve differing environmental factors. Patients with isolated EA/TEF (n = 98), isolated ARM (n = 123), and the combined phenotype (n = 42) were included. Families were recruited within the context of two German multicenter studies of the genetic and environmental causes of EA/TEF (great consortium) and ARM (CURE-Net). Exposures of interest were ascertained using an epidemiological questionnaire. Chi-square, Fisher's exact, and Mann-Whitney U-tests were used to assess differences between the three phenotypes. Newborns with isolated EA/TEF and the combined phenotype had significantly lower birth weights than newborns with isolated ARM (P = 0.001 and P < 0.0001, respectively). Mothers of isolated EA/TEF consumed more alcohol periconceptional (80%) than mothers of isolated ARM or the combined phenotype (each 67%). Parental smoking (P = 0.003) and artificial reproductive techniques (P = 0.03) were associated with isolated ARM. Unexpectedly, maternal periconceptional multivitamin supplementation was most frequent among patients with the most severe form of disorder, i.e. the combined phenotype (19%). Significant differences in birth weight were apparent between the three phenotype groups. This might be attributable to the limited ability of EA/TEF fetuses to swallow amniotic fluid, thus depriving them of its nutritive properties. Furthermore, the present data suggest that fore- and hindgut malformations involve differing environmental factors. Maternal periconceptional multivitamin supplementation was highest among patients with the combined phenotype. This latter finding is contrary to expectation, and warrants further analysis in large prospective epidemiological studies.

Abstract
The treatment of esophageal atresia is not centralized in Germany. Therefore, high numbers of departments are involved. Data on the results of esophageal atresia repair from Germany are lacking. The aim of this study was to evaluate the early postoperative results after repair of esophageal atresia based on unbiased data of a German health insurance. We aimed to determine whether characteristics of the departments had an impact on outcome and compared the results from this study with the literature data from centers with a high caseload. Data of a German health insurance covering ∼10% of the population were analyzed. All patients who had undergone esophageal atresia repair from January 2007 to August 2012 were included. Follow-up data of 1 year postoperatively were analyzed. The potential impact of various characteristics of the treating surgical institutions was assessed. Results were compared with the latest international literature. Seventy-five patients with esophageal atresia underwent reconstructive surgery in 37 departments. The incidences of anastomotic leak (3%) and recurrent tracheoesophageal fistula (7%) were comparable with the literature (both 2-8%). Anastomotic stricture required dilatation in 57% of patients (mean 5.1 ± 5.6 dilatations) comparing unfavorably to most, but not all international reports. During 1-year follow-up, 93% of the patients were readmitted at least once (mean 3.9 ± 3.1 admissions). The incidence of complications did not correlate with any of the characteristics of the treating institutions such as academic affiliation, the number of consultants, beds, and preterm infants treated per year (all P > 0.05). Based on unbiased data, postoperative results after repair of esophageal atresia in Germany are comparable with recently published reports from international single centers. A correlation between the complication rate and characteristics of the treating institutions was not identified.

Abstract
BACKGROUND Healthcare is increasingly influenced by economical constraints which can lead to ethical conflicts for surgeons. The aim of the study was to investigate the incidence of these conflicts and the coping strategies of surgeons. METHODS A prospective, standardized staff survey in an academic pediatric surgical department was performed over a period of 4 weeks. The types of conflict and solution strategies were determined. The agreement with given statements was determined using a 5-point Likert scale. RESULTS In 155 returned questionnaires 74 ethical conflicts were identified. Most conflicts concerned decisions relating to diagnosis-related groups (DRG) which were economically based. To resolve the ethical conflict surgeons decided to the detriment of patients in 73 % and to the economical benefit in 72 %. In 8 % a medical disadvantage for the patient was noted and in 62 % a disadvantage for patient comfort was seen. Surgeons were highly dissatisfied with the conflict solutions (2.3/5). CONCLUSIONS Economical considerations cause ethical conflicts in the daily routine in pediatric surgery. Decisions are made to the benefit of the hospital and cause a decrease in patient comfort. Political solutions for this problem are required in the interest of all those involved.

Abstract
BACKGROUND The neonatal surgical patient is threatened by exuberant inflammatory reactions. Neonatal macrophages are key players in this process. We investigated the ability of neonatal macrophages to initiate a local inflammatory reaction upon exposure to different bacterial or viral ligands to toll-like receptors (TLRs). METHODS Peritoneal wash outs from neonatal (<24 h) and adult (42 days) C57BL/6J mice were gained by peritoneal lavages. In a first set of experiments, macrophages were purified and stimulated for 6 h by four different TLR ligands. mRNA was extracted for transcriptome analysis. In a second set of experiments, lipopolysaccharide was applied into peritoneal cavities. After 6 h of incubation, the cellular composition of the inflamed cavities was evaluated by cytological staining as well as chipcytometry. RESULTS Neonatal murine peritoneal macrophages differed significantly in the expression of pro- and anti-chemotactic genes. Functional assignment of these genes revealed enhanced chemotactic potential of neonatal macrophages and was confirmed by a higher influx of pro-inflammatory cells into neonatal peritoneal cavities. CONCLUSION Neonatal peritoneal macrophages demonstrated an enhanced chemotactic potential upon stimulation with four TLR ligands. This was associated with an increased influx of inflammatory cells to the peritoneal cavity. This might contribute to the strong inflammatory responses of neonates and preterms.

Abstract
INTRODUCTION The lack of young physicians in Germany, who are willing to train in surgery, is caused by several factors. Due to the demographic development and the specialisation in paediatric surgery in university institutions, attracting trained paediatric surgeons became difficult for non-specialised rural paediatric surgical departments, which is often also complicated by economic pressures. Strategies, such as cooperation between hospitals or departments, are required. We present a mid-term analysis of the first paediatric surgical cooperation between a university clinic and a rural paediatric surgical department in Lower Saxony. METHODS The Department of Pediatric Surgery, Hannover Medical School (MHH), is a university centre with a case load of about 1,700 surgical procedures per year with a case mix index (CMI) of 1.3. The Department of Paediatric Surgery, St. Bernward Hospital Hildesheim (BK), is a peripheral institution with about 1,200 surgical procedures per year and a CMI of 0.5. A cooperation project was inaugurated in October, 2004, between the two departments. The aim of the cooperation was to support the head of the paediatric surgical department at the BK by rotating trained paediatric surgeons from the MHH. Simultaneously, it was planned to offer attractive conditions for research at MHH for participating surgeons. The cooperation further included sufficient economic cover of 1.5 posts for rotating medical staff by the BK. RESULTS Three trained paediatric surgeons have so far been included in the rotation programme between the two cooperating paediatric surgical departments. The rotating medical staff costs were covered by the BK. Over a period of 2.5 years, MHH surgeons performed about 50 % of all surgical procedures at BK, while undertaking two-thirds of on-call duties there. Analysis of academic research revealed 3 accomplished experimental and 4 clinical studies, as well as 10 published articles. CONCLUSIONS The paediatric surgical cooperation was rated as a success by the rotating trained paediatric surgeons, the heads of both departments and the hospital administrations. The academic link to a university clinic also increased the attractiveness to work in a paediatric surgical department at a rural hospital.

Abstract
Minimally invasive techniques are well established in numerous paediatric surgical departments. They are safely applied to children of all age groups. Numerous types of procedures have been established specifically for children and, therefore, the necessary expertise cannot be derived from general surgical experience. Advantages in postoperative symptoms, convalescence and cosmesis have been confirmed. However, data or recommendations concerning the use outside of centres of paediatric surgery are lacking. In the opinion of the authors, minimally invasive paediatric surgery should only be considered for departments with a volume of paediatric specialty operations similar to that of paediatric surgical centres. In addition, an adequate number of operations, specific expertise of the surgeons in minimally invasive paediatric surgery, and specific expertise of anaesthesiologists is mandatory. Today, these prerequisites can only be assumed for non-paediatric specialty operations, such as laparoscopic appendectomy. In conclusion, before recommendations can be made for minimally invasive techniques in specialty paediatric operations outside of paediatric surgical centres, the feasibility and safety under these conditions has to be investigated.

Abstract
In surgical medicine there are traditions, myths, rites and dogmas which define concepts of treatment and strategies. Upheld and passed on without being examined or confirmed in further studies, these concepts and strategies include preoperative intestinal lavage and fasting, postoperative long-term drainage, tubes und catheters, long-term relaxation of the intestine after abdominal surgery or immobilisation for some days. New techniques and procedures in surgery and anaesthesia, including postoperative pain management like laparoscopic surgery and partial anaesthesia, reduce the need for surgery and minimize morbidity of treatment. For more than ten years now, the Copenhagen abdominal surgeon Henrik Kehlet and his team have systematically dealt with the question of how to reduce perioperative stress and improve postoperative conditions of recovery. The resulting concepts of an "enhanced recovery after surgery" (ERAS) seek to overcome handed-down myths und fix new clinical pathways. In current prospective studies of elective surgery, the clinical use of these fast track concepts have been confirmed in colon surgery, pediatric surgery and urology. Here, examples of some of these studies are discussed together with problems like general complications and length of stay, while aspects of insurance are also taken into consideration.

Abstract
Initial surgical therapy of biliary atresia (BA) consists of the radical excision of extrahepatic remnants and portoenterostomy. However, despite this procedure, which was introduced by Kasai, BA remains the commonest indication for paediatric liver transplantation. The goal of the work group on the technical aspects of Kasai portoenterostomy procedures during the European Biliary Atresia Registry Conference 2007 was to achieve consensus on various operative and perioperative aspects relevant for paediatric surgeons. Although there is still disagreement regarding some of the technical details of the Kasai operation, a remarkable consensus has emerged in most areas of the actual surgery. No consensus was achieved on the role of postoperative drainage, the routine application of steroids, the use of oral prophylactic antibiotics, and the treatment of postoperative cholangitis. Nevertheless, the wide variation in reported results, which was a feature of this conference, suggests that there are still areas where improvement in outcomes can be anticipated by changes in technique or practice.

Abstract
BACKGROUND This study aimed to determine the impact of prior surgery on the feasibility of laparoscopic surgery for children. METHODS A prospective study analyzed 471 consecutive children who underwent laparoscopic surgery over a 4-year period. Laparoscopic procedures were classified "easy," "difficult," or "demanding." The end points of the study were conversion rate, intraoperative events, and duration of operation. RESULTS A total of 89 patients (19%) had undergone previous abdominal surgery. The conversion rate was 18% for the patients with prior surgery versus 9% for those without a prior operation (16/89 vs 35/382; p < 0.05). This difference reflects a significantly higher conversion rate for "easy" procedures among patients with than among those without prior surgery, but not for "difficult" and "demanding" procedures. The type of prior surgery had no significant impact on the mean duration of the operation. Of 71 procedures, 12 (17%) after prior conventional surgery were converted, as compared with 4 (22%) of 18 after prior laparoscopy (p > 0.05). Intraoperative events, mainly attributable to adhesions and lack of overview, occurred in 8% of patients with prior procedures, as compared with 2% without former surgery (7/89 vs 9/382; p < 0.05). Relevant complications were not significantly more frequent after prior surgery. The incidence of conversions decreased with increased time between current and previous surgery. It was 64% for surgeries less than 1 year later, 25% for surgeries 1 to 5 years later, and 5% for surgeries more than 5 years later (7/11 vs 6/24 vs 3/54; p < 0.001). CONCLUSIONS Prior surgery has a limited impact on the feasibility of laparoscopic surgery for children. The conversion rate and the incidence of intraoperative events, mainly because of adhesions and lack of overviewing, is increased, but not the incidence of relevant complications. The feasibility improves considerably with increased time between surgery and prior surgery. The authors consider laparoscopy to be the first-choice technique after prior surgery.

PURPOSE We analyzed the feasibility of laparoscopic nephroureterectomy in children younger than 1 year, with regard to size of impaired kidney. MATERIALS AND METHODS A total of 40 consecutive children underwent transperitoneal laparoscopic nephrectomy during a 4-year period. Of the patients 19 (48%) were younger than 1 year and were analyzed in detail. Nine of these patients (47.4%) had a multicystic dysplastic kidney, 9 (47.4%) had reflux nephropathy and 1 (5.3%) had obstructive nephropathy. The duration of operation, reasons for conversion, and intraoperative and postoperative complications were prospectively documented. RESULTS Mean operative time was 133 minutes (range 60 to 240), and did not differ significantly between patients up to age 12 months compared to children 1 year and older (126 vs 148 minutes, NS). Nephroureterectomy was completed laparoscopically in 17 of 19 children (89%) up to age 12 months vs 20 of 21 (95%) 1 year and older (NS). In 1 child younger than 1 year suture dislocation at the renal artery required laparoscopic resuturing. No further complications were seen. In children younger than 1 year the mean operating time was not significantly different for resection of multicystic dysplastic kidney (8 patients, 113 minutes) compared to reflux nephropathy (9, 134 minutes, NS). Mean operating time did not differ significantly for kidney volumes less than 10 cc (8 patients, 119 minutes) compared to kidney volumes greater than 10 cc (9, 129 minutes, NS). CONCLUSIONS The feasibility of transperitoneal laparoscopic nephroureterectomy in children younger than 1 year is excellent. The duration of operation is not affected by patient age, underlying disease or kidney size.

Abstract
PURPOSE The present study was performed to compare dissection of the renal hilar vessels in laparoscopic transabdominal nephrectomy in children using the Endo-Ligasure vessel sealing system versus clip/ligation. PATIENTS AND METHODS In a prospective and comparative study carried out from February 2003 to April 2004, 10 consecutive patients (group 1) underwent laparoscopic transabdominal nephroureterectomy using clips or intracorporeally performed ligations, respectively. From April 2004 to April 2005, 10 consecutive patients (group 2) underwent the same procedure using the Endo-Ligasure vessel sealing system. Indications for surgery were confirmed non-functioning kidneys secondary to benign unilateral renal disease and no prior surgery. The age and underlying disease distribution and the affected side were not significantly different between the two groups. RESULTS The operating time was significantly lower in the Endo-Ligasure group (group 1: median 167 vs. group 2: 108 min, p < 0.05). Bleeding of the renal artery occurred due to dislocation of a suture ligation, which was treated laparoscopically with an intracorporeal suture ligation. Blood loss was negligible in all patients. All procedures were completed laparoscopically and recovery was uneventful. CONCLUSIONS Endo-Ligasure is a beneficial tool in laparoscopic transabdominal nephrectomy. It is safe, effective, and reduces operating times compared to clip application and intracorporeal suturing.

Abstract
BACKGROUND The anaesthetic management of small infants during advanced laparoscopic surgery can be complicated by the major pathophysiological effects of increased intra-abdominal pressure. In this study haemodynamic, acid-base and blood volume changes were investigated during pneumoperitoneum in a small animal model. METHODS Ten fasted, anaesthetized, mechanically ventilated and multi-catheterized New Zealand rabbits were randomized to carbon dioxide pneumoperitoneum (PP, duration 210 min, pressure 8 mm Hg) or control group. Cardiac index was determined using trans-cardiopulmonary thermodilution and total blood volume was measured by thermal-dye dilution with indocyanine green using a fibreoptic monitor system. RESULTS In PP cardiac index (CI), central venous oxygen saturation (Scv(O(2))), total blood volume (TBV) and base excess (BE) decreased significantly during the study whereas all variables remained constant in the control group. After release of PP the measured variables did not return to baseline within 30 min [PP, baseline vs study end: CI 108 (22) vs 85 (14) ml kg(-1) min(-1), Scv(O(2)) 81.4 (8.9) vs 56.7 (9.8)%, TBV 318 (69) vs 181 (54) ml, BE -1.9 (2.7) vs -8.7 (1.8) mmol litre(-1); P<0.01]. CONCLUSION Our animal model suggests that a decrease in CI, metabolic acidosis and hypovolaemia could occur after prolonged low pressure pneumoperitoneum in small infants, which is possibly not detectable by the standard monitor setting. Therefore, the routine use of an extended monitoring including measurement of central venous oxygen saturation and acid-base parameters should be considered during and soon after operation, when pneumoperitoneum will last longer than 2 h.

Abstract
PURPOSE The "minimally invasive repair of pectus excavatum" (MIRPE) has increasingly become the standard operation for the repair of pectus excavatum. The aim of the present study was to report on our first-line postoperative results, including a survey of patients and to elucidate the acceptance of MIRPE. PATIENTS AND METHODS All MIRPE patients, who were operated on between 2000 and 2004 in our departments, were included in a retrospective study. In 2002, a retrospective questioning of 57 patients was initiated by sending identical questionnaires separately to both the patients and their parents asking for individual reasons for choosing and/or agreeing to MIRPE. RESULTS Complications were seen in 25 out of 84 MIRPE patients (mean 14 years, range from 5 to 20 years), but most of them were minor. Removal of the bar was necessary in 6 cases, due to bar displacement, secondary haematothorax, pericardial effusion, and local infection, respectively. No major complications occurred in the age group between 9 and 14 years. More than 90 % of the patients and their parents were satisfied or highly satisfied with the MIRPE procedure. CONCLUSION General and specific complications are similar to other series and they decrease with the surgeon's experience. The most severe problem, occurring in older patients, is how to avoid dislocation of the pectus bar. In the light of the complication rate, the acceptance of MIRPE is still high, especially in adolescents and young adults who had refused operation with the open techniques. In this way, a shifting of a paradigm is taking place.

Abstract
PURPOSE We assessed the feasibility of laparoscopic transabdominal dismembered pyeloplasty in 46 infants and children with regard to patient age. MATERIALS AND METHODS A total of 46 consecutive infants and children (31 male and 15 female) underwent laparoscopic transabdominal dismembered pyeloplasty using a 3 to 4-trocar technique. All patients had confirmed unilateral deterioration of renal function on isotope renography. The 46 patients were divided into 3 age groups--1 to 12 months (group 1, 14 patients), 1 to 7 years (group 2, 15 patients) and 7 to 18 years (group 3, 17 patients). Followup included clinical and ultrasound assessment, and isotope renography at 3 months. RESULTS Laparoscopic pyeloplasty was feasible in 44 of 46 patients (96%). Mean operative time was 175 minutes (range 120 to 270). The operation was converted due to impracticality of stenting the PUJ in 1 patient, and due to bleeding in 1. Mean operative time in 44 successful laparoscopic procedures was not significantly different among the 3 age groups (171 minutes in group 1, 169 minutes in group 2 and 173 minutes in group 3). Two patients required operative intervention for PUJ leakage, and 1 underwent percutaneous nephrostomy with a further uneventful course. Mean followup was 29 months (range 3 to 86). A total of 44 patients (96%) were asymptomatic and had improved PUJ drainage on isotope renography. Two patients underwent redo pyeloplasty due to recurrent hydronephrosis at 1 month and 2 years. CONCLUSIONS Laparoscopic transabdominal dismembered pyeloplasty is effective and safe in infants and children. The feasibility is also excellent in patients younger than 1 year. The transabdominal approach revealed good exposition without a disadvantage for the patient.

Abstract
BACKGROUND The improved outcome after endoscopic surgery has been attributed to less surgical trauma. However, the underlying mechanisms are not fully understood, and direct effects of CO2 used for pneumoperitoneum, cellular acidification, and/or the lack of air contamination have been postulated to additionally modulate immune functions during endoscopic surgery. We investigated the effects of CO2 incubation, extracellular acidification, and air contamination on the inflammatory response of two distinct macrophage populations. METHODS R2 and NR 8383 rat macrophage cell lines were used. Interleukin-6 (IL-6) and nitric oxide after lipopolysaccharide (LPS) stimulation were determined in these sets of experiments: incubation in 100% CO2, 5% CO2, and room air for 2h; incubation at pH 7.4, 6.5, and 5.5 for 2 h in 5% CO2; and incubation in 100% CO2, 5% CO2 and room air in fixed pH 6.3. The extracellular pH was monitored during incubation. We determined the alteration of intracellular pH in cells subjected to extracellular acidification by fluorescence microscopy. RESULTS Extracellular pH decreased to 6.3 during 100% CO2 incubation. IL-6 release was reduced after CO2 incubation in NR 8383 cells and increased in R2 cells (p < 0.05). It was not altered by air incubation. Decreasing the extracellular pH to 6.5 mimicked the effects of CO2 and a decrease to 5.5 suppressed IL-6 release in both cell lines. In fixed pH at 6.3, CO2 and air incubation had no effect. CO2 and pH had no impact on nitric oxide release and vitality. Intracellular pH decreased with extracellular acidification without significant difference between the two cell lines. CONCLUSIONS A decrease in extracellular pH during incubation in CO2 differentially affects IL-6 release in macrophage subpopulations. This may explain contradictory results in the literature. Moreover, we demonstrated that air contamination does not affect macrophage cytokine release. The decrease in extracellular pH is the primary underlying mechanism of the alteration of macrophage cytokine release after CO2 incubation, and it appears that the ability to maintain intracellular pH is not determined by the effects of CO2 or extracellular acidification.

Abstract
BACKGROUND There is no generally accepted standard surgical approach to gastrooesophageal reflux disease (GERD) at present. However, laparoscopic fundoplication has been advocated to be the procedure of choice for gastrooesophageal reflux disease in children. We aimed to assess the standards of the diagnostic workup and operative techniques in paediatric surgical institutions in Germany. MATERIAL AND METHODS A questionnaire including 14 items was sent to all 71 departments of paediatric surgery in Germany. Forty (56 %) took part in the survey. Concepts of routine diagnostic workup, operative techniques, number of procedures, and conversions were assessed. RESULTS The average annual frequency of fundoplications was less than 20 in 36 units (90 %). Experience with laparoscopic fundoplication was present in 24 institutions (60 %). In 19 out of these (79 %) fewer than 50 laparoscopic fundoplications had been performed altogether up to the time of the survey. Out of 584 fundoplications performed in the year 2002, 184 (32 %) had been done laparoscopically. The ratio of conventional versus laparoscopic fundoplication was 170/130 (57/43 %) in academic, and 226/54 (81/19 %) in non-academic departments. The preferred technique of fundoplication, irrespective of the approach, was the Nissen wrap in 28 (70 %) of the departments. The number of paediatric surgeons performing laparoscopic fundoplication was 1 - 2 in 16 institutions (67 %), 3 or 4 in 6 (25 %), and 5 in 2 (8 %) departments. The conversion rate was reported to be less than 5 % in 15 departments (63 %), and 5 - 10 % in 3 (13 %). CONCLUSION The laparoscopic approach for surgical repair of GERD in children is not yet generally accepted in Germany. In most departments, training remains problematic due to low numbers of procedures. However, the feasibility of laparoscopic fundoplication in Germany is excellent, with a low rate of conversions.

Abstract
BACKGROUND Progressive familial intrahepatic cholestasis results in fibrosis, cirrhosis, and liver insufficiency if untreated. Medical therapy often fails and partial external biliary diversion has been recommended to prevent early liver transplantation. We present a new technique of performing a laparoscopic partial external biliary diversion and report our experience in a first series of infants. METHODS From October to November 2004, four consecutive patients with progressive familial intrahepatic cholestasis underwent the laparoscopic partial biliary diversion procedure. A three-trocar technique was used. A proximal jejunal conduit was constructed after exteriorization of the small bowel via the infraumbilical trocar incision. After repositioning of the bowel, an isoperistaltic cholecystojejunostomy was carried out laparoscopically. The distal jejunal conduit was placed as a stoma at the right abdominal trocar site. RESULTS There were no intraoperative events. The mean duration of the operation was 156.5 min. The postoperative course was uneventful in all patients with full enteral feedings on day 2. The laboratory and clinical signs of cholestasis were reduced up to a mean follow-up of 2 months (range, 1.5-2.5). CONCLUSION The laparoscopic partial biliary diversion procedure is feasible with all the benefits of minimally invasive surgery. Long-term results remain to be evaluated.

Abstract
Numerous investigators have shown that video-assisted thoracoscopic surgery (VATS) can be safely used for specific conditions of newborns, infants, and children. The technique has been postulated to be associated with a lower morbidity, shorter hospital stay, lower costs, and clinical results similar to those achieved by open surgery. The present article reviews the state of the art of VATS for thoracic conditions in children. Most authors focus on the feasibility of single procedures, and only a small number of reports deals with the feasibility in series with multiple types of procedures and larger numbers of patients. Therefore, systematic research on the advantages and limits of VATS in children remains mandatory.

Abstract
INTRODUCTION Transient oliguria during laparoscopic surgery is a known phenomenon. Currently, no data on the impact of pneumoperitoneum on renal function in children are available. PATIENTS AND METHODS Thirty children with normal kidney function, who underwent laparoscopic surgery, were included in a prospective study. A transurethral catheter was placed to measure urine output during and 6 hours after operation. Renal blood flow (resistive index) was evaluated by Doppler ultrasound of a segmental renal artery before surgery, every 15 minutes during laparoscopy, and after 24 hours. Blood and urine samples were studied before and 24 hours after surgery. Hemodynamic parameters were monitored continuously during standardized anesthesia, including a standardized intravenous infusion regimen. RESULTS Urine output decreased within 45 minutes of pneumoperitoneum in all patients. Of 8 children younger than 1 year, 7 (88%) developed anuria vs 3 of 22 (14%) children aged 1 to 15 years (P < .001). Nine children 1 year and older (32%) developed oliguria. There was a significant recovering in the mean urine output until 5 to 6 hours after pneumoperitoneum in both age groups. No significant alterations of the renal blood flow (resistive index) and the serum and urine levels of cystatin C, creatinine, and urea nitrogen were evident until 24 hours postoperatively. The volume of infusion during pneumoperitoneum did not correlate with urine output. CONCLUSION Pneumoperitoneum leads to anuria in most children younger than 1 year and to oliguria in about one third of older children. This is a completely reversible phenomenon. Urine output should not be taken into consideration for calculating intravenous fluid administration during pneumoperitoneum in children.

Abstract
BACKGROUND The feasibility of laparoscopic resection of choledochal cyst and hepaticojejunostomy in children is still unclear. This report presents the author's experience with a first series of patients. METHODS Data from 11 consecutive children (median age 17.5 months, SD 22, range 2 to 70) with choledochal cyst scheduled for laparoscopy were collected prospectively. There were nine type I and 2 type V cysts according to Todani's classification. All except one patient had intermittent jaundice or recurrent pancreatitis. The laparoscopic technique included excision of the cyst. A Roux-en-Y anastomosis was constructed after exteriorization of the small bowel via the infraumbilical trocar incision. After repositioning of the bowel an end-to-side hepaticojejunostomy was carried out laparoscopically. RESULTS The procedures were carried out in nine children without intraoperative events and a median duration of 289 min (SD 62). In two patients, the operation was converted after 60 and 90 min due to a lack of overview at the dorsal margin with problems in separation of the portal vein. Oral food intake was started within 2 days and tolerated well in all except one patient, in whom biliar fluid from the drain led to laparoscopic reevaluation on day 1. A small leak was resutured and the patient was discharged on day 5. In one patient, recurrent cholangitis and a dilated Roux-en-Y loop led to correction of some kinking of the loop via laparotomy after 3 months. All other patients are well with bile-stained stools after a mean follow-up of 13 months. CONCLUSIONS Laparoscopic resection of congenital choledochal cyst and choledochojejunostomy in children is feasible. We feel that there is a considerable learning curve with the technique. Future studies will have to prove the feasibility of laparoscopic Roux-en-Y bowel anastomosis without the need for bowel exteriorization.

Abstract
BACKGROUND Immune function is better preserved by laparoscopic versus conventional surgery. Numerous mediators of the systemic trauma response are synthesized and/or regulated by the liver. However, it has been stated that the advantages of laparoscopic surgery are no more obvious when conventional operations are performed via mini-laparotomy. We set out to compare the impact of laparoscopy and mini- and full laparotomy on the hepatic macrophage populations. METHODS Male Lewis rats were subjected to anesthesia alone (control), mini-laparotomy (1 cm), full laparotomy (7 cm), or laparoscopy for 60 min. Endpoints were the total protein in the peritoneal lavage fluid, hepatic ED-1 cells (recruited monocytes), hepatic ED-2 cells (Kupffer cells), the expression of OX-6 in the liver, and C-reactive protein (CRP) in plasma. RESULTS Protein in the peritoneal lavage fluid increased significantly after all interventions. Full laparotomy was accompanied by an enhancement in ED-1-positive monocytes in the liver parenchyma compared to all other groups (p < 0.001). Mini- and full laparotomy led to an increase in ED-2-positive Kupffer cells (p < 0.001). Laparoscopy did not affect the number of monocytes/macrophages. There was no significant alteration of OX-6 expression in either group. No change in the cellular composition in the periportal fields was observed. The CRP plasma levels did not significantly differ between groups. CONCLUSIONS Laparoscopy completely prevents hepatic macrophage populations from expansion and normal cell disposition is preserved. Laparotomy, irrespective of incision size, increases the number of Kupffer cells. Moreover, full laparotomy, but not mini-laparotomy or laparoscopy, causes an increase in hepatic monocyte recruitment. The regulating pathways after surgery differ from other immunologic challenges, such as sepsis, in which immunocompetent cells accumulate and are stimulated in the periportal fields.

Abstract
The incidence of abdominal symptoms after cholecystectomy in adults is high. Up to one third of the patients consult a doctor because of abdominal complaints within 1 year after the operation. In addition, a higher incidence of colon carcinoma after cholecystectomy has been reported in female patients. This article reviews the known facts on the "postcholecystectomy syndrome". However, little is known about postcholecystectomy symptoms in children. Reports on cholecystectomy in children deal rather with feasibility than long-term outcome. Therapeutic concepts for children with symptomatic gallstone disease should consider the differences in the etiology of gallstone formation between children and adults. Therefore, we recommend a specific concept, including laparoscopic cholecystotomy, for children with temporary disorders causing gallstones, and laparoscopic cholecystectomy for all other patients. The impact of these procedures on postcholecystectomy symptoms in children and the impact of cholecystectomy during childhood on the incidence of right-sided colonic carcinoma remains to be determined.

Abstract
TOPIC Laparoscopic fundoplication is the preferred surgical procedure for children with gastro-oesophageal reflux. Little data exist on the feasibility of laparoscopic fundoplication after placement of a percutaneous endoscopic gastrostomy (PEG). PATIENTS AND METHODS Thirty-nine children aged 4 months to 18 years (median 3.6 years) presented for an antireflux procedure between November 2000 and July 2003. The surgical technique used was the Thal (270 degrees ) fundoplication. Clinical data, technical aspects of the operation, and the postoperative course were collected prospectively. RESULTS Twenty-two children (56 %), all of them neurologically impaired, already had a PEG in place due to feeding problems irrespective of gastro-oesophageal reflux symptoms. In all cases, laparoscopic fundoplication was performed immediately after gastroscopic removal of the PEG tube. In two cases, conversion to an open procedure became necessary, due to reasons unrelated to the PEG. In one case conversion was necessary because of adhesions of an intrathoracic stomach and in the other case because of circulatory problems due to congenital cardiomyopathy. In one patient, the gastrostomy was moved at the end of the procedure because it was too close to the antrum. In two further cases, the gastrostomy detached during fundoplication. In this case, the gastrostomy catheter was replaced and secured laparoscopically with a purse-string suture. All other cases were without any complications and a balloon tube or a button was placed into the existing gastrostomy channel at the end of surgery. CONCLUSION No adverse effects are associated with PEG placement prior to a consecutive laparoscopic antireflux procedure. Possible detachment of the pre-existing gastrostomy must be excluded at the end of the procedure.

Abstract
As the laparoscopic approach to gastroesophageal reflux disease (GERD) was introduced in pediatric surgery in the last decade of the 20th century, it became apparent that this approach was beneficial. The favorable results have led to a more general acceptance and implementation of this type of surgery at the beginning of the 21st century. We give an overview of the first decade of laparoscopic antireflux procedures in children with an emphasis on the laparoscopic Thal fundoplication and its implication on morbidity and cure of GERD in the long term both for normal and mentally handicapped children. Between 1993 and 2002, 149 children with GERD underwent 157 laparoscopic antireflux procedures, of whom 48% were mentally handicapped. Follow-up ranged from 6 months to 9 years (median age 4.5 years). Nineteen children died. All but one were not related to the antireflux procedure. Immediate relief of symptoms occurred in 120 children (80.5%). In 29 children, the results were less than optimal. Eight patients underwent a laparoscopic redo procedure (5.4%). However, none of the children with a follow-up of more than 5 years show any symptoms anymore. In conclusion, the laparoscopic Thal fundoplication is a safe procedure, and results in the long term are favorable, irrespective of the nature of the cause, ie, mental retardation.

Abstract
The main problem with biliary atresia (BA) is three-fold. Early diagnosis and timely therapy is mandatory in this rare and life-threatening disease. In as much as the aetiology of BA is unknown, all therapeutic attempts are still symptomatically orientated and finally, at the end-stage of the disease, the majority of the patients need organ replacement. Due to promising interdisciplinary cooperation and improved outcomes after liver transplantation, the overall survival rate of patients with BA increased remarkably during the last decades. Additionally, every effort was made in clinical and basic research to obtain a better understanding of the disease and its clinical course. Nevertheless, the nature of biliary atresia still remains unclear and therapeutic options are unsatisfactory. Numerous papers about BA have appeared, reflecting clinical and scientific activity. Considering recent publications and prospective activities, in the following we will summarise what is new in biliary atresia.

Abstract
We report the case of a 3450 g newborn girl with prenatally diagnosed duodenal obstruction. At operation, duodenal atresia due to annular pancreas and intestinal, partially volvulated malrotation became apparent. Surgical correction was completely laparoscopic with 3-mm instruments. The operation consisted of reduction of the volvulated bowel loops, division of obstructing bands, and creation of a side-to-side duodenoduodenostomy. The technique, described in detail, proved to be feasible. No postoperative complication occurred and the girl is doing well 4 months postoperatively.

Abstract
There has been substantial progress in minimally invasive techniques in children in recent years. Numerous investigators have shown that laparoscopic and thoracoscopic paediatric surgery can be performed safely. It has been postulated that minimally invasive paediatric surgery is associated with low morbidity, a shorter hospital stay, lower costs and clinical results similar to those achieved by open surgery. The present article reviews information from the past 2 years on the pathophysiological effects, feasibility, standards, new techniques, the importance of the method in malignant diseases and robotics. However, most of these reports still focus on safety and feasibility. It would be preferable if the paediatric surgical society itself would discriminate between useful and useless or harmful techniques. Therefore, further systematic research on the advantages and limits of minimally invasive surgery in children is mandatory.

Abstract
As the laparoscopic approach to gastroesophageal reflux disease (GERD) was introduced in pediatric surgery in the last decade of the 20th century, it became apparent that this approach was beneficial. The favorable results have led to a more general acceptance and implementation of this type of surgery at the beginning of the 21st century. We give an overview of the first decade of laparoscopic antireflux procedures in children with an emphasis on the laparoscopic Thal fundoplication and its implication on morbidity and cure of GERD in the long term both for normal and mentally handicapped children. Between 1993 and 2002, 149 children with GERD underwent 157 laparoscopic antireflux procedures, of whom 48% were mentally handicapped. Follow-up ranged from 6 months to 9 years (median age 4.5 years). Nineteen children died. All but one were not related to the antireflux procedure. Immediate relief of symptoms occurred in 120 children (80.5%). In 29 children, the results were less than optimal. Eight patients underwent a laparoscopic redo procedure (5.4%). However, none of the children with a follow-up of more than 5 years show any symptoms anymore.

Abstract
BACKGROUND Advantages of laparoscopic surgery have, among other factors, been attributed to a shorter length of abdominal incision and the use of CO2 versus air. An analysis of these factors taking pressure-induced alterations into account is lacking. The objective of the study was to determine the impact of laparoscopy and laparotomy with exposure to CO2 and room air under a similar pressure on local, systemic, and distant organ immune responses. METHODS Twenty piglets were randomized into four groups: CO2 laparoscopy, air laparoscopy, CO2 laparotomy, and air laparotomy. Laparotomy was performed in a sterile balloon pressurized similar to laparoscopy. Peritoneal interleukin-1, interleukin-6, tumor necrosis factor-a, and counts of polymorphnuclear cells (PMNs), and macrophages (MFs) were determined in abdominal lavage fluids at 0, 2, and 48 h. Macrophages were assessed for reactive oxygen species (ROS) production. Systemic responses were gauged by white blood cell count (WBC) and cytokines. Alveolar lavage was performed at 48 h to determine cytokine levels, cell counts, and MF ROS production. Blood, lavage fluids, and mesenteric lymph nodes were tested for bacterial translocation. RESULTS Regarding the peritoneal response, laparotomy versus laparoscopy when performed with CO2 significantly increased PMN and decreased the percentage of macrophages (%MF) up to 48 h. There was a significant increase in interleukin-6, and there was a fourfold increase in MF ROS production. Similar differences between the procedures were found with exposure to air. The use of air versus CO2 in laparoscopy, but not in laparotomy, resulted in an increase of peritoneal PMN and a decrease of the %MF up to 48 h. Air increased the local interleukin-6 release in both procedures and increased MF ROS production fourfold. Regarding the systemic response, laparotomy produced a significant increase in WBC, which was significantly more pronounced with exposure to air. No alteration of other systemic cytokines was seen. Regarding the pulmonary response, the number of MFs and MF ROS production were significantly increased after air versus CO2 laparoscopy. There were no such differences between the laparotomy groups. Regarding bacterial translocation, no bacteria were cultured from peritoneal fluids, lymph nodes, or blood. CONCLUSIONS Inflammatory responses were reduced by a laparoscopic approach and by exposure to CO2 versus air. Peritoneal responses were affected to a larger degree than systemic parameters. Laparotomy overruled the effects of CO2 on chemotaxis and distant organ injury but not on peritoneal cytokine release.

Abstract
Pediatric surgery in The Netherlands differs from pediatric surgery in other European countries. This article deals with the general structure of Dutch pediatric surgery and some of its particularities. Although pediatric surgery is not officially recognized in The Netherlands, the Dutch have found a way of selecting and centralizing children who need surgical therapy in 6 centers of excellence. This has been mainly achieved by agreements between scientific professional organizations. The limited number of academic pediatric surgical centers guarantees a high quality of skill and care, and a lot of clinical exposure for trainees. On the other hand, allowing general surgeons to do most of the surgery in children, albeit the less complicated procedures, may not be ideal. The limited number of trainees does not allow for a nation-wide training program. The small number of pediatric surgeons and trainees make pediatric surgery in The Netherlands vulnerable, both in field of care as well as in the field of research. As pediatric surgery in The Netherlands is not recognized as such, pediatric surgeons who have been trained in most of the other European countries but have not completed their general surgery training, cannot be employed as pediatric surgeons in The Netherlands. However, pediatric surgery in The Netherlands has found a comparatively clear way of defining its distinctive areas of clinical work. It cannot be overlooked and is well established in the academic centers of the country.

Abstract
Laparoscopic cholecystectomy (LCE) has become the procedure of choice for symptomatic gallstones in children. However, there is concern about the disadvantages of cholecystectomy. Numerous postoperative symptoms and a possible correlation of the procedure with a higher incidence of right-sided colon carcinoma have been described. Therefore, it has been suggested to remove the gallstones via a cholecystotomy, leaving the gallbladder in place. This is the first report on the functional and symptomatic outcome of laparoscopic cholecystotomy (LCO) versus LCE in a consecutive series of children. A follow-up study of all children who underwent surgery for symptomatic gallstone disease from 1993 to 1999 was performed. Nine underwent LCO and 8 standard LCE. The procedure was chosen according to the preference of the surgeon. Patients and parents underwent a standardized follow-up interview. The intensitiy of six gastrointestinal symptoms was graded from 0 to 3. The patients and parents scored the symptomatic outcome using a 100-point visual analogue scale. There were no intraoperative complications. Bleeding of a port site required suturing in 1 patient after LCO, and fever with a further uneventful course occurred in another after LCE. The mean duration of hospital stay was 3.0 days after LCO and 2.4 days after LCE. In 1 patient a missed gallstone was identified 4 weeks after LCO. The patient underwent LCE with a further uneventful course. At follow-up (mean 20.7 months after LCO, 28.3 months after LCE, P = n.s.) there was a tendency toward a lower incidence of symptoms after LCO. Symptoms were reported by 3 of 8 patients after LCO and 5 of 8 after LCE. The mean score of the symptomatic outcome was not statistically different. All patients with LCO were free of stones on ultrasound examination with normal contraction of the gallbladder. LCO thus represents an alternative approach. We consider LCO for children with symptomatic cholecystolithiasis before the onset of puberty. However, data on the long-term outcome from larger series are mandatory before a general recommendation can be given.

Abstract
BACKGROUND Some authors have argued that intussusception is best treated via a laparoscopic approach. As we did not have this impression, we reviewed our experience with this condition. METHODS : We reviewed all patients with intussusception who were treated at our hospital over the past 10 years. The choice of whether to use a laparoscopic or open approach depended on the patient's clinical condition and the availability of surgeons with laparoscopic expertise. RESULTS A total of 72 patients were identified. Based on age, two subgroups were distinguished-one comprised of patients under the age of 3 years and one of patients over the age of 3 years. Sixty-five patients were under 3 years of age. Thirty-five had surgery, and 19 required resection. Of the 10 patients who were treated with a laparoscopic approach, only three could be reduced laparoscopically. After conversion in the other seven patients, the intussusception was reduced in five whereas a resection was required in two cases. Seven patients were 3 years of age or older. All of them underwent surgery, and all but one required resection. All four children who were laparoscoped subsequently had a bowel resection at open surgery. CONCLUSIONS Patients 3 years of age or older usually need resection and will not benefit from the laparoscopic approach. Under 3 years of age, little is to be gained from a laparoscopic approach, provided good nonsurgical reduction facilities are available. There is a place for the laparoscopic approach in cases of recurrent intussusception or doubtful reduction.

Abstract
A 3,220-g newborn baby with trisomy 21 presented with duodenal atresia. No other congenital malformations were diagnosed. Informed consent for a laparoscopic approach was obtained. The child was placed in a supine, head-up position slightly rotated to the left at the end of a shortened operating table. The surgeon stood at the bottom end with the cameraperson to his left and the scrub nurse to his right. The screen was at the right upper end. Open insertion of a cannula for a 5-mm 30 degrees telescope through the inferior umbilical fold was performed. A carbon dioxide (CO2) pneumoperitoneum with a pressure of 8 mmHg and a flow of 2l/min was established. Two 3.3-mm working cannulas were inserted; one in the left hypogastrium and one pararectally on the right at the umbilical level. Two more such cannulas were inserted; one under the xyphoid for a liver elevator and one in the right hypogastrium for a sucker. Mobilization of the dilated upper and collapsed lower duodenum was easy. After transverse enterotomy of the upper duodenum and longitudinal enterotomy of the distal duodenum, a diamond-shaped anastomosis with interrupted 5 zero Vicryl sutures were performed. The absence of air in the bowel beyond the atresia increased the working space and greatly facilitated the procedure. The technique proved to be easy, and the child did very well. Laparoscopic bowel anastomosis in newborn babies had not been described previously. Recently, a diamond-shaped duodenoduodenostomy for duodenal atresia was performed. The technique proved to be simple and is described in detail. The child did very well.

Abstract
BACKGROUND This study investigates the feasibility of performing a subsequent laparoscopic antireflux procedure after former placement of a percutaneous endoscopic gastrostomy (PEG). METHODS Between 1997 and 1998, five patients with a gastrostomy in place presented with an indication for laparoscopic antireflux procedure due to persisting vomiting. RESULTS All patients were managed laparoscopically with a four-trocar technique. CONCLUSIONS Primary PEG placement has no adverse effects on a later secondary antireflux procedure. In some cases, four rather than five trocars can be used.

Abstract
BACKGROUND Gastroesophageal fundoplication currently is one of the three most common major operations performed on infants and children by pediatric surgeons in the United States. With the advent of laparoscopic surgery, the number of gastroesophageal fundoplications has virtually exploded. Morbidity always was substantial with this operation, and laparoscopy has not changed this. We describe our results with laparoscopic refundoplication in infants and children. METHODS From December 1993 to December 1998 100 children underwent a laparoscopic 180 degrees anterior wrap using the Thal procedure. Four children had to undergo a laparoscopic refundoplication. Two of these children were mentally handicapped. All of the children had recurrent symptoms, but only two of the four had an abnormal pH study. In three of the children, the Thal procedure was changed to a Nissen (n = 2) and Toupet (n = 1) fundoplication. One child with an intrathoracic wrap and a giant hiatal hernia underwent hernia repair with a Goretex patch and a redo-Thal. RESULTS In two of the children, the operation was relatively simple. For one child, the procedure had to be converted for anesthesiologic reasons. The procedure in the fourth child was more difficult because of a large hiatal hernia. Within a follow-up time of 2 to 4 years, all the children were free of pathologic gastroesophageal reflux symptoms and afterward displayed no recurrence. CONCLUSION In children, laparoscopic refundoplication after a previous laparoscopic antireflux Thal procedure is feasible and does not increase morbidity.

Abstract
BACKGROUND/PURPOSE The feasibility of laparoscopy in children and its impact on routine pediatric surgery are not well established. The purpose of this study was to determine the role of laparoscopy in a university department of pediatric surgery. METHODS All children undergoing laparoscopy during the period of 1 year were included in a prospective trial. Data on patients, the operation, technical problems, intraoperative events, and the postoperative course were documented using standardized questionnaires. All patients underwent at least 1 follow-up assessment 2 weeks after the operation. All conventional abdominal operations performed during the same period were analyzed for comparison purposes. RESULTS Of 244 abdominal operations performed during the study period, 147 (60.2%) were laparoscopies. One hundred twenty-three (83.7%) of these included a laparoscopic operation, and 24 (16.3%) were diagnostic procedures. Of 26 types of laparoscopic operations 3 were performed more than 15 times (fundoplication, appendectomy, pyloromyotomy), and 9 types were performed once. Problems with instruments and devices led to a mean time loss of 15.1 minutes in 15.6% of the procedures. The conversion rate was 10.1% mainly because of complicated appendicitis. Fifty-six children (38.1%) weighed less than 10 kg, and the conversion rate did not correlate with the body weight. There was 1 (0.07%) intraoperative event. A small bowel perforation was identified immediately and resolved with an uneventful course. Postoperative complications included an incisional hernia in 3 children and an incisional leakage of liquor in 1 child with a ventriculoperitoneal drain. There was a reprolaps after laparoscopic correction of an ileostomy in 1 child and fever in another. In 3 newborns the diagnosis was missed during laparoscopy and had to be established by laparotomy later with an uneventful course. Primary conventional operations were mainly restricted to bowel resection and anastomosis performed in 52 of 97 laparotomies. CONCLUSIONS The authors showed that 60% of abdominal operations in children can be performed via laparoscopy. Most types of laparoscopic operations are not performed frequently, but the feasibility of the technique in routine use is excellent. However, the performance of instruments should be improved further, and laparoscopy for establishing the diagnosis in newborns remains difficult.

Abstract
UNLABELLED 38 totally or partially incontinent patients following imperforate anus repair (age 6-15 years) tested a new polyurethane (PU) anal plug against another, widely used anal plug (PVA) in a randomized crossover trial. Plugs were tested 3 weeks each, data concerning bowel habits, handling and plug-related problems were collected by questionnaire before trial, at time of product change and after trial. RESULTS 15 of 38 patients did not complete the protocol, among them 6 with anal canal diameters too small for the smallest plug. During plug use, patients experienced enhanced awareness of repletion and urge. Stool consistence did not change in 82% of patients. There were no changes in children constipated prior to study (n = 8/23). 12,123 children were absolutely clean during use of either plug. 15 patients (68%) using the PU plug and 10 (45%) using the PVA plug felt secure from soiling during plug use. 74% of patients preferred the PU plug. Painful plug insertion, a feeling of pressure inside the anal canal and painful plug removal were reported with both plugs, but were less frequent with the PU plug. CONCLUSION Anal plugs, regardless of their make, offer absolute cleanliness for periods of several hours to 66% of our incontinent patients. The PU plug (Conveen, Coloplast) is preferred by the patients and offers greater security than the PVA plug.

Abstract
Mutations in the steroidogenic acute regulatory protein (StAR) gene cause congenital lipoid adrenal hyperplasia, characterized by diminished or absence of adrenal and gonadal steroids, resulting in severe adrenal insufficiency and ambiguous or complete female external genitalia in genetic males. We report on a 15-yr-old 46,XY phenotypic female, referred because of lack of pubertal development. ACTH and gonadotropin concentrations were elevated; and aldosterone, cortisol and its precursors, and sex steroids before and after stimulation were below the lower limit of detection. In the StAR gene, a homozygous nonsense mutation (TGG --> TAG) in exon 7 (W250X) was identified. Histologic examination after gonadectomy showed seminiferous tubules containing immature Sertoli cells and a few single germ cells with positive placental-like alkaline phosphatase immunoreactivity, indicating carcinoma in situ. This is the first report on testicular morphology, at a pubertal age, in a female patient with 46,XY karyotype and a mutation in the StAR gene, in whom gonadal neoplasia had developed.

Abstract
A total of 106 consecutive children with intestinal neuronal malformations were included in a prospective study. The intestinal transit time was assessed using a modification of Hinton's method. The results of transit time studies, the associated specific histochemical findings, therapeutic procedures, and the clinical course on follow-up assessments over a mean period of 2.4 years were analysed. The intestinal transit time was prolonged in all 53 patients with aganglionosis and in 37 (69.8%) out of 53 children with other intestinal malformations. Eight out of 16 children with IND type B had an abnormal transit time, 1 underwent anterior resection, and 2 had a temporary colostomy. In 7 out of 8 children with hypoganglionosis and 9 out of 10 children with a reduced parasympathetic tone the transit time was prolonged. A resection was performed in 7 and 2 of these children respectively. Both patients with heterotopia of the myenteric plexus had a prolonged bowel transit and parts of the large bowel had to be resected. Only 11 out of 17 children with heterotopia of the submucous plexus, dysganglionosis, or immature ganglia had a prolonged transit time, 2 underwent sphincteromyotomy. At follow-up, all patients with malformations other than aganglionosis stated that symptoms had improved and they were willing to tolerate their complaints. However, 25 reported on persistent constipation, 6 on overflow encopresis. All children who required surgery had a prolonged intestinal transit time, but also 21 (56.8%) of 37 children who were successfully treated without surgery. None of the 16 children with normal transit had to be operated. It is concluded that specific histochemical findings do not always correlate with delayed intestinal transport. The determination of the intestinal transit time represents an important tool to identify the clinical relevance of histochemical findings in the individual patient.

Abstract
A detailed analysis of the hospital-related costs of laparoscopic cholecystectomy in children was performed. Data on 10 laparoscopic cholecystectomies were collected prospectively. Pre-, intra- and postoperative variables were assessed by standardized questionnaires. The hotel costs and costs for nursing, physicians, medicaments and equipment were calculated in detail. Reusable instruments were assumed to be used for 50 operations per year over 5 years and the costs for disposable instruments were calculated for comparison. In addition, the data of 10 children who underwent open cholecystectomy were analyzed retrospectively. The mean hospital costs for one laparoscopic cholecystectomy was 3685 DM. The costs for the operation itself represented 36.5% of the hospital costs and were mainly due to expenses for surgeons and nurses. The costs for laparoscopic equipment and instruments represented only 8.5% of the total costs. If an open procedure instead of a laparoscopic operation had been performed with a similar duration of hospital stay, the hospital costs would have been reduced by 425 DM (11.5%). In laparoscopic cholecystectomy the costs for medical treatment in addition to the operation were 32.8% of the total costs and were mainly due to expenses for nursing and physicians, which added up to 165 DM per day. The hotel costs represented 30.7% of the total costs and added another 189 DM per day. Therefore, potential savings in the operation theatre are limited and most effective savings may be achieved by shortening the hospital stay. The use of disposable instruments would have increased the costs by 844 DM and already 20 operations per year would have been cheaper performed with reusable compared to disposable instruments. Reusable instruments are recommended. Additional 60 minutes operating time cost 312 DM (5.20 DM/minute) and therefore, laparoscopic training courses for surgeons may be cost-effective in order to reduce the costs for training in the operation theatre.

Abstract
In a prospective study 106 children with intestinal neuronal malformations underwent intestinal transit-time studies. In only 50% of the children with intestinal neuronal dysplasia type B or immature ganglia was the transit time prolonged. On the contrary, hypoganglionosis and heterotopia of the submucous plexus led to severe transport disorders with subsequent bowel resection.

Abstract
PURPOSE To examine the quality of life after repair of esophageal atresia, follow-up studies were performed in 58 of 71 surviving patients (81.7%). METHODS Fifty patients with primary anastomosis and all eight surviving patients with colon interposition were seen. The mean age was 25.3 years (range, 20 to 31). Symptoms were evaluated by a standardized interview. Quality of life assessment was performed using a visual analogue scale (0 to 100 points), the Spitzer Index (5 dimensions, 10 points), and the Gastrointestinal Quality of Life Index (GIQLI, 5 dimensions, 128 points). RESULTS After primary anastomosis the estimated meal capacity was unrestricted in 46 patients (92%), but numerous symptoms such as recidivating cough (60%), hold up (48%), and short breath (30%) were reported. All symptoms except cough were seen more frequently in patients with colon interposition, and all of these patients suffered from periods of short breath. Quality of life scores were higher in patients with primary anastomosis compared with colon interposition. The difference in the visual analogue scale score did not reach statistical significance, but the mean Spitzer Index was 9.7 compared with 8.8 after colon interposition (P < .05). The GIQLI after primary anastomosis was similar to that in healthy controls and was significantly lower in patients with colon interposition. This was because of specific symptoms, which scored 49.3 after colon interposition compared with 61.7 after primary anastomosis (P < .05) and to 54.8 (SD 5) in healthy controls (P < .05). Physical and social functions, emotions, and inconvenience of a medical treatment scored similar in patients with primary anastomosis, colon interposition, and healthy volunteers. CONCLUSIONS The long-term quality of life after primary anastomosis was excellent. Patients with colon interposition suffer more frequently from various gastrointestinal and respiratory symptoms, but they lead an otherwise normal life.
