Franzini S, Querciagrossa S, Brebion M, Lapenta C, Blanc T, Orliaguet G. Expanding safety boundaries in pediatric robotic-assisted laparoscopic surgery: are we protecting our children? J Robot Surg 2024; 18:185. [PMID: 38683478 DOI: 10.1007/s11701-024-01959-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Accepted: 04/19/2024] [Indexed: 05/01/2024]
Abstract
Little is known about the effects of CO2 insufflation (CDI) on cerebral oxygen saturation (CrSO2) during laparoscopy in the pediatric population. In children undergoing robotic-assisted laparoscopic pyeloplasty (RALP), we prospectively assessed the effects of CDI using standard monitoring and cerebral near-infrared spectroscopy (NIRS). We also explored whether a correlation existed between CrSO2 and parameters known to affect cerebral blood flow. Between January 2021 and September 2023, a cohort of consecutive children older than 2 years underwent RALP at Necker-Enfants Malades Hospital in Paris. A ventilation protocol aimed to prevent hypercarbia was implemented. Data collected included standard monitoring parameters and CrSO2 by NIRS. Thirty patients (16 females), mean age 5.5 ± 3.9 (2.0-9.5) years, were included. Twenty-three patients underwent a retroperitoneal approach. The mean baseline CrSO2 value was 83.0 ± 9.8. Mean CrSO2 decreased during progressive CDI, never below baseline values, while standard-monitoring parameters did not significantly change. No significant correlation was detected between CrSO2 and end tidal CO2, or between CrSO2 and mean arterial pressure, at any operative time. During RALP, a gradual CDI doesn't cause pathological derangements of CrSO2. The lack of correlation between CrSO2 and standard parameters affecting cerebral blood flow suggests the likely presence of cerebral autoregulation in our population.

Abstract
Objective This study aimed to evaluate respiratory parameters during percutaneous internal ring suturing (PIRS) for inguinal hernia repair in two different-aged pediatric patients in whom the airway is provided with a laryngeal mask or endotracheal tube for general anaesthesia. Methods After local ethics committee and parental consent, 180 ASAI-II children were randomly allocated to 4 groups; according to their age (0-24 months / 25-144 months) and airway device laryngeal mask (LMA) / endotracheal tube (ETT) used for general anaesthesia (45 children each) for laparoscopic inguinal hernia repair. Standard anaesthesia induction was done with lidocaine, propofol, and fentanyl, and 0.6 mg kg-1 rocuronium was added to the ETT groups. Sevoflurane is used for maintenance. Hemodynamic parameters, peak airway pressure, end-tidal carbon dioxide (EtCO2), and peripheric oxygen saturation (SpO2) values were recorded after induction, before, and during pneumoperitoneum. The duration of anaesthesia, surgery, recovery time, and surgical satisfaction was recorded. Airway complications (cough, laryngospasm, bronchospasm, desaturation, and aspiration) were recorded. Results Hundred and eighty patients (45 in each group) were analyzed. Duration of surgery and surgical satisfaction were similar in all groups. Duration of anaesthesia and recovery times were significantly shorter in the LMA groups. Peak airway pressure and EtCO2 levels were significantly lower in the LMA groups. Rare airway complications were observed without significance. Conclusion In laparoscopic inguinal hernia repair with the PIRS technique, LMA offered comparable operating conditions and surgical satisfaction.

Abstract
BACKGROUND Pediatric robotic-assisted surgeries have increased in recent years; however, guidance documents are still lacking. This study aimed to develop evidence-based recommendations, or best practice statements when evidence is lacking or inadequate, to assist surgical teams internationally. METHODS A joint consensus taskforce of anesthesiologists and surgeons from the Italian Society of Pediatric and Neonatal Anesthesia and Intensive Care (SARNePI) and the Italian Society of Pediatric Surgery (SICP) have identified critical areas and reviewed the available evidence. The taskforce comprised 21 experts representing the fields of anesthesia (n = 11) and surgery (n = 10) from clinical centers performing pediatric robotic surgery in the Italian cities of Ancona, Bologna, Milan, Naples, Padua, Pavia, Perugia, Rome, Siena, and Verona. Between December 2020 and September 2021, three meetings, two Delphi rounds, and a final consensus conference took place. RESULTS During the first planning meeting, the panel agreed on the specific objectives, the definitions to apply, and precise methodology. The project was structured into three subtopics: (i) preoperative patient assessment and preparation; (ii) intraoperative management (surgical and anesthesiologic); and (iii) postoperative procedures. Within these phases, the panel agreed to address a total of 18 relevant areas, which spanned preoperative patient assessment and patient selection, anesthesiology, critical care medicine, respiratory care, prevention of postoperative nausea and vomiting, and pain management. CONCLUSION Collaboration among surgeons and anesthesiologists will be increasingly important for achieving safe and effective RAS procedures. These recommendations will provide a review for those who already have relevant experience and should be particularly useful for those starting a new program.

Anaesthesia management during paediatric robotic surgery: preliminary results from a single centre multidisciplinary experience. Anaesth Crit Care Pain Med 2021; 40:100837. [PMID: 33757915 DOI: 10.1016/j.accpm.2021.100837] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2020] [Revised: 02/12/2021] [Accepted: 02/13/2021] [Indexed: 02/07/2023]
Abstract
INTRODUCTION Paediatric robotic surgery is gaining popularity across multiple disciplines and offers technical advantages in complex procedures requiring delicate dissection. To date, limited publications describe its perioperative management in children. MATERIAL & METHODS We retrospectively analysed the prospectively collected anaesthetic data of the first 200 robotic-assisted surgery procedures in our paediatric university hospital as part of a multidisciplinary program from October of 2016 to February of 2019. Anaesthetic technique and monitoring were based on guidelines initially derived from adult data. We examined adverse events and particular outcomes including blood loss and analgesic requirements. RESULTS Fifty-one different surgical procedures were performed in patients aged 4 months to 18 years (weight 5-144 kg). Operative times averaged 4 h and conversion rate was 3%. Neither robotic arm nor positional injury occurred. Limited access to the patient did not lead to any complication. Hypothermia was frequent and mostly self-limiting. Negative physiological effects due to positioning, body cavity insufflation or surgery manifesting as significant respiratory and haemodynamic changes occurred in 14% and 11% of patients, respectively. Overt haemorrhage complicated one case. Eighty per cent of 170 patients did not require level 3 analgesics postoperatively, while thoracic and certain tumour cases had greater analgesic requirements. CONCLUSION These preliminary results show that paediatric robotic surgery is well tolerated with a low bleeding risk and that major intraoperative events are uncommon. A consistent anaesthetic approach is effective across a broad range of procedures. Analgesic requirements are low excluding thoracic and some complex abdominal cases. Future studies should focus on the rehabilitative aspects of robotic surgery technique.

Abstract
BACKGROUND Capnoperitoneum provides a ventilatory challenge due to reduction in end-expiratory lung volume and peritoneal carbon dioxide absorption in both children and adults. The primary aim of this controlled interventional trial was to determine the positive end-expiratory pressure (PEEP) level needed to ensure for adequate carbon dioxide clearance and preservation of carbon dioxide homeostasis in an experimental model of infant laparoscopy. The secondary aim was to evaluate potential effects on cardiac output of PEEP and abdominal pressure level variations in the same setting. METHODS Eight chinchilla bastard rabbits were anesthetized and mechanically ventilated. Intra-abdominal pressures were randomly set to 0, 6, and 12 mm Hg by carbon dioxide insufflation. Carbon dioxide clearance using volumetric capnography, arterial blood gas data, and cardiac output was recorded, while PEEP 3, 6, and 9 cmH2 O were applied in a random order. RESULTS A PEEP of 9 cmH2 O showed restoration of carbon dioxide clearance without causing changes in arterial partial pressure of carbon dioxide and bicarbonate and with no associated deterioration in cardiac output. CONCLUSION The results promote a PEEP level of 9 cmH2 O in this model of infant capnoperitoneum to allow for adequate carbon dioxide removal with subsequent preservation of carbon dioxide homeostasis. The use of high PEEP was not associated with any decrease in cardiac output.

Abstract
BACKGROUND Thoracoscopic plication has gained popularity in the management of diaphragmatic eventration, and several suturing techniques have been described. However, the superiority of one technique over the other has not been demonstrated. The purpose of this study is to report our experience with diaphragmatic plication and to compare the thoracoscopic interrupted and pleated suture techniques in pediatric patients with diaphragmatic eventration. METHODS This is a retrospective cohort study (level of evidence: 3) performed on 14 patients with diaphragmatic eventration. All patients were symptomatic and had diaphragmatic plication via thoracoscopy. The patients were further divided into two groups according to the repair technique; interrupted repair (n = 9) and pleated repair (n = 5). Preoperative, operative and postoperative data were compared between the two groups. RESULTS The median age was 9.5 months (25th- 75th percentiles: 6 to 15 months), and 8 (57%) were males. Twelve patients (85.71%) had right side eventration, and nine patients (64.29%) had congenital diaphragmatic eventration. One case was converted to open thoracotomy because of adhesions. There was no difference in the preoperative characteristics between both groups. Median operative time was 117 min (25th- 75th percentiles: 101-129 min) and 77 min (25th- 75th percentiles: 73-83 min) in the interrupted and pleated groups, respectively (p = 0.004). One patient had a postoperative elevation of the diaphragm (incomplete repair) in the pleated group (p = 0.357). No recurrence was reported during the follow-up. CONCLUSION Thoracoscopic plication is an effective technique for management of diaphragmatic eventration in children. Pleating technique is easy, fast, and associated with a marked reduction in operative time. TYPE OF THE STUDY Retrospective cohort study. LEVELS OF EVIDENCE Level of evidence: 3.

Abstract
Background and Aims: Supraglottic airways used in pediatric surgeries are associated with a lesser number of postanesthesia respiratory complications. However, there is limited literature on the use of i-gel for pediatric laparoscopic surgery. The aim of this study is to assess the adequacy of ventilation of i-gel for pediatric laparoscopic surgery and note any associated adverse event. Material and Methods: This is a single-centered prospective observational study including 119 children, aged 6 months to 18 years, scheduled for laparoscopic surgery, during a 9-month period, in a tertiary care center. I-gel was used for positive pressure ventilation, and if the post-insertion oropharyngeal seal pressure was <25 cm H2O, it was replaced with a tracheal tube. Adequacy of ventilation and adverse events were noted. Results: Data from 102 cases were analyzed (17 cases excluded: tracheal intubation in 11; missing data in 6 cases). The mean oropharyngeal seal pressure was 34.2 ± 5.2 cm H2O and mean airway pressure was 16.1 ± 2.4 cm H2O. The adverse events included transient cough (10.7%), sore throat (4.9%), and desaturation (3.9%). There was no sign of respiratory distress during the recovery and no intervention was required in any child postoperatively. Conclusion: I-gel provided adequate ventilation of the lungs in children undergoing laparoscopic surgery with no major adverse event.

Abstract
INTRODUCTION Surgical management of jejuno-ileal atresia/stenosis (JIA) is shifting to a minimally invasive approach. Our purpose is to evaluate the safety and feasibility of laparoscopy-assisted surgery (LAS) in JIA by comparing outcomes with a control group of open surgery (OS). METHODS A retrospective review of JIA cases was performed. Demographic, surgical, and outcomes data were extracted. LAS cases were compared with OS. Fisher's exact-test for qualitative and Mann-Whitney-test for quantitative values were used. p values <0.05 were considered significant. RESULTS Forty-seven patients (24/23, F/M) were included. In 19 (40%), the LAS technique was successfully performed, while 3 (17%) required conversion to OS. No differences were observed between the LAS and OS (n = 28) groups concerning demographic data (sex, mean gestational age, mean weight, associated anomalies) and type of JIA. Operative time was shorter in LAS (112 ± 46 min) compared to OS (138 ± 40 min), p = 0.04. Time to start enteral feeding and time to full enteral was shorter in LAS compared to OS, p = 0.04. No difference was observed between the two groups concerning duration of parenteral nutrition, length of hospitalization and weight at discharge. Overall rate of postoperative complications was 14% (n = 7), with a slightly prevalence in OS (18%) compared to LAS (10%), p = 0.68. CONCLUSIONS The LAS technique in the treatment of neonatal JIA is safe and feasible. LAS is associated with shorter operative and restoration of enteral feeding times. The post-operative outcomes in LAS are similar with OS, with a lower rate of postoperative complications.

Abstract
Pediatric robotic-assisted laparoscopic procedures are becoming increasingly common. They have been shown to be safe in younger patients, including infants. Successful adoption of robotic-assisted surgery in infants requires an understanding of the technical factors unique to this patient population. This review will delineate the specific considerations to safely perform robotic-assisted laparoscopic procedures in infants, including physiological changes associated with pneumoperitoneum in infants, positioning, trocar placement, and docking.

Partial amniotic carbon dioxide insufflation (PACI) involves insufflating the amniotic sac with carbon dioxide (CO2 ) and, in some cases, draining some of the amniotic fluid. The creation of a gaseous intra-amniotic compartment improves visualization, even in the presence of limited bleeding, and creates the work space required for complex fetoscopic procedures. Clinically, PACI is mostly used to perform fetoscopic myelomeningocele (MMC) repair, enabling a minimally invasive alternative to open fetal surgery. However, evidence of the fetal safety of PACI is limited. Previous animal experiments in sheep demonstrate that PACI induces fetal hypercapnia and acidosis with largely unknown short and longer term implications. In this review, we examine the literature for the physiological effects of intrauterine insufflation pressure, duration, humidity, and the role of maternal hyperventilation on fetal physiology and well-being.

Outcomes of laparoscopic and open surgery in children with and without congenital heart disease. J Pediatr Surg 2018; 53:1980-1988. [PMID: 29157923 PMCID: PMC5957762 DOI: 10.1016/j.jpedsurg.2017.10.052] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2017] [Revised: 10/17/2017] [Accepted: 10/20/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND Children with congenital heart disease (CHD) often require noncardiac surgery. We compared outcomes following open and laparoscopic intraabdominal surgery among children with and without CHD. METHODS We performed a retrospective cohort study using the 2013-2015 National Surgical Quality Improvement Project-Pediatrics. We matched 45,012 children <18years old who underwent laparoscopic surgery to 45,012 children who underwent open surgery. We determined the associations between laparoscopic (versus open) surgery and 30-day mortality, in-hospital mortality, 30-day morbidity, and postoperative length-of-stay. RESULTS Among children with minor CHD, laparoscopic surgery was associated with lower 30-day mortality (Odds Ratio [OR] 0.34 [95% Confidence Interval 0.15-0.79]), inhospital mortality (OR 0.42 [0.22-0.81]) and 30-day morbidity (OR 0.61 [0.50-0.73]). As CHD severity increased, this benefit of laparoscopic surgery decreased for 30-day morbidity (ptrend=0.01) and in-hospital mortality (ptrend=0.05), but not for 30-day mortality (ptrend=0.27). Length-of-stay was shorter for laparoscopic approaches for children at cost of higher readmissions. On subgroup analysis, laparoscopy was associated with lower odds of postoperative blood transfusion in all children. CONCLUSIONS Intraabdominal laparoscopic surgery compared to open surgery is associated with decreased morbidity in patients with no CHD and lower morbidity and mortality in patients with minor CHD, but not in those with more severe CHD. LEVEL-OF-EVIDENCE Level III: Treatment Study.

Abstract
BACKGROUND Minimal access surgery (MAS) has gained popularity in infants less than 5kg, however, significant challenges still arise in very low weight infants. STUDY DESIGN A retrospective chart review was performed to identify all infants weighing less than 3kg who underwent an advanced MAS or equivalent open procedure from 2009 to 2016. Advanced case types included Nissen fundoplication, duodenal atresia repair, Ladd procedure, congenital diaphragmatic hernia repair, esophageal atresia/tracheoesophageal fistula repair, diaphragmatic plication, and pyloric atresia repair. A comparative analysis was performed between the MAS and open cohorts. RESULTS A total of 45 advanced MAS cases and 17 open cases met the inclusion criteria. Gestational age and age at operation were similar between the cohorts, while infants who underwent open procedures had significantly lower weight at operation (p=0.003). There were no deaths within 30days related to surgery in either group. Only 3 MAS cases required unintended conversion to open. There were 2 (4.4%) postoperative complications related to surgery in the MAS cohort and 2 (11.8%) in the open cohort. CONCLUSION Advanced MAS may be performed in infants weighing less than 3kg with low mortality, acceptable rates of conversion, and similar rates of complications as open procedures. TYPE OF STUDY Prognosis study. LEVEL OF EVIDENCE Level III.

Abstract
Adaptive changes in oxygenation and hemodynamics are evaluated during pediatric laparoscopy. The children underwent laparoscopy (LAP Group, n=20) or open surgery (Open Group, n=10). Regional cerebral (rScO2) and peripheral oxygen saturation (SpO2), heart rate (HR), diastolic (DP) and systolic pressure (SP) were monitored at different intervals: basal (T0); anesthesia induction (T1); CO2PP insufflation (T2); surgery (T3); CO2PP cessation (T4); before extubation (T5). At T1, in both the LAP and Open groups significant changes in rScO2, DP and SP were recorded compared with T0; a decrease in SatO2 was also observed at T5. In the LAP group, at T2, changes in HR related to CO2PP pressure and in DP and SP related to IAP were noted; at T4, a SP change associated with CO2PP desufflation was recorded. Open group, at T3 and T5 showed lower rScO2 values compared with T1. Pneuperitoneum and anesthesia are influent to induce hemodynamics changes during laparoscopy.

Abstract
OBJECTIVES To determine the risk of morbidity and mortality after laparoscopic surgery among children with congenital heart disease (CHD). STUDY DESIGN Cohort study using the 2013-2014 National Surgical Quality Improvement Program-Pediatrics, which prospectively collected data at 56 and 64 hospitals in 2013 and 2014, respectively. Primary exposure was CHD. Primary outcome was overall in-hospital postoperative mortality. Secondary outcomes included 30-day mortality and 30-day morbidity (any nondeath adverse event). Among 34?543 children who underwent laparoscopic surgery, 1349, 1106, and 266 had minor, major, and severe CHD, respectively. After propensity score matching within each stratum of CHD severity, morbidity and mortality were compared between children with and without CHD. RESULTS Children with severe CHD had higher overall mortality and 30-day morbidity (OR 12.31, 95% CI 1.59-95.01; OR 2.51, 95% CI 1.57-4.01, respectively), compared with matched controls. Overall mortality and 30-day morbidity were also higher among children with major CHD compared with children without CHD (OR 3.46, 95% CI 1.49-8.06; OR 2.07, 95% CI 1.65-2.61, respectively). Children with minor CHD had similar mortality outcomes, but had higher 30-day morbidity compared with children without CHD (OR 1.71, 95% CI 1.37-2.13). CONCLUSIONS Children with major or severe CHD have higher morbidity and mortality after laparoscopic surgery. Clinicians should consider the increased risks of laparoscopic surgery for these children during medical decision making.

Laparoscopy in children and its impact on brain oxygenation during routine inguinal hernia repair. J Minim Access Surg 2017; 13:51-56. [PMID: 27251842 PMCID: PMC5206840 DOI: 10.4103/0972-9941.181800] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Accepted: 03/19/2016] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND The systemic impact of intra-abdominal pressure (IAP) and/or changes in carbon dioxide (CO2) during laparoscopy are not yet well defined. Changes in brain oxygenation have been reported as a possible cause of cerebral hypotension and perfusion. The side effects of anaesthesia could also be involved in these changes, especially in children. To date, no data have been reported on brain oxygenation during routine laparoscopy in paediatric patients. PATIENTS AND METHODS Brain and peripheral oxygenation were investigated in 10 children (8 male, 2 female) who underwent elective minimally invasive surgery for inguinal hernia repair. Intraoperative transcranial near-infrared spectroscopy to assess regional cerebral oxygen saturation (rScO2), peripheral oxygen saturation using pulse oximetry and heart rate (HR) were monitored at five surgical intervals: Induction of anaesthesia (baseline T1); before CO2insufflation induced pneumoperitoneum (PP) (T2); CO2PP insufflation (T3); cessation of CO2PP (T4); before extubation (T5). RESULTS rScO2decreases were recorded immediately after T1 and became significant after insufflation (P = 0.006; rScO2decreased 3.6 ± 0.38%); restoration of rScO2was achieved after PP cessation (P = 0.007). The changes in rScO2were primarily due to IAP increases (P = 0.06). The HR changes were correlated to PP pressure (P < 0.001) and CO2flow rate (P = 0.001). No significant peripheral effects were noted. CONCLUSIONS The increase in IAP is a critical determinant in cerebral oxygenation stability during laparoscopic procedures. However, the impact of anaesthesia on adaptive changes should not be underestimated. Close monitoring and close collaboration between the members of the multidisciplinary paediatric team are essential to guarantee the patient's safety during minimally invasive surgical procedures.

Abstract
OBJECTIVE A safe and optimal pneumoperitoneal pressure (PP) for laparoscopic renal surgery in infants is difficult to define. In a broad sense, a safe and optimal PP should cause least intraoperative and postoperative physiological stress for the infants and should be optimal for surgeon's technical feasibility. Unfortunately, the safe and optimal PP in infant for transperitoneal laparoscopic surgery has not been established by well validated study. To determine safe and optimal PP for laparoscopic renal surgery (LRS) in infants less than 10 kg. METHOD In a prospective and randomized setting, between July 2008 and June 2014, 46 infants of <10 kg (Group I, n = 23, PP = 6-8 mmHg and Group II, n = 23, PP = 9-10 mmHg) who underwent LRS, were analyzed. Hemodynamic, respiratory, and blood gas changes were measured at four points: before CO2 insufflation (T0), 10 min after insufflation (T1), before desufflation (T2) and 10 min after desufflation (T3). Any required adjustments of ventilator parameters were noted. Time to resume feeding and postoperative pain at 1, 6, and 12 h, including requirement for postoperative rescue analgesia, were assessed. Technical feasibility with allocated PP was evaluated by means of successful completion of surgery, duration of surgery, and intraoperative complications. RESULTS At T1 and T2, changes in hemodynamic and respiratory parameters were significantly higher in Group II. At T3, most of the parameters statistically restored back to baseline in Group I but not so in Group II. Required adjustments in ventilatory parameters were 14 vs. 25 times in Group I vs. Group II (p = 0.007, R = 0.552). Mean postoperative pain score, requirement for analgesia, and time to resume feeding were significantly greater in Group II. Surgeries were successfully completed in all the patients in both groups, with comparable duration of surgery and similar intraoperative complications (Table). CONCLUSION It was found that hemodynamic and respiratory changes were more pronounced with higher pneumoperitoneal pressure in infants for renal laparoscopic surgery. With a PP of 6-8 mmHg, intraoperative accessibility is optimal, and physiological changes are minimal. Interestingly, we found that infants with PP of 6-8 mmHg enjoy smooth and early postoperative recovery. There was no direct objective criterion to assess level of difficulty with allocated PP, which may be considered a limitation of the present study. Pneumoperitoneal pressure of 6-8 mmHg appears to be a safe and optimal range for transperitoneal laparoscopic renal surgery in infants.

Abstract
PURPOSE It is assumed that laparoscopic surgery generally induces less inflammatory responses than open surgery. Since few studies have compared immune responses after laparoscopic and open surgery in children, we examined inflammatory markers in children randomized to open (ONF) or laparoscopic Nissen fundoplication (LNF). METHODS Blood samples were collected prior to surgery (D0), and on postoperative day 1 (D1) and day 2 (D2). Inflammatory markers were measured using a multiplex antibody bead kit. The postoperative levels of inflammatory markers were statistically analyzed using a linear mixed model. A P value <0.05 was considered statistically significant. RESULTS Twenty-nine patients randomized to ONF or LNF were included. Median age was 3.1 years (range 1.0-14.2) in the ONF group and 4.0 years (range 0.2-14.2) in the LNF group. Plasma levels of the anti-inflammatory cytokine interleukin (IL)-10 were significantly higher in the ONF group than in the LNF group postoperatively (P = 0.04). However, there were no significant differences between the groups in the levels of pro-inflammatory markers tumor necrosis factor-α, IL-6, IL-8, monocyte chemoattractant protein-1, white blood cell count, or C-reactive protein. CONCLUSIONS We did not find that laparoscopy induced a substantially less inflammatory response than laparotomy in children undergoing fundoplication.

Abstract
This review article focuses on neonatal respiratory physiology, mechanical ventilation of the neonate and changes induced by anesthesia and surgery. Optimal ventilation techniques for preterm and term neonates are discussed. In summary, neonates are at high risk for respiratory complications during anesthesia, which can be explained by their characteristic respiratory physiology. Especially the delicate balance between closing volume and functional residual capacity can be easily disturbed by anesthetic and surgical interventions resulting in respiratory deterioration. Ventilatory strategies should ideally include application of an 'open lung strategy' as well avoidance of inappropriately high VT and excessive oxygen administration. In critically ill and unstable neonates, for example, extremely low-birthweight infants surgery in the neonatal intensive care unit might be an appropriate alternative to the operating theater. Best respiratory management of neonates during anesthesia is a team effort that should involve a joint multidisciplinary approach of anesthetists, pediatric surgeons, cardiologists, and neonatologists to reduce complications and optimize outcomes in this vulnerable population.

Abstract
PURPOSE Diaphragmatic plication by minimally invasive surgery is thought to allow for a quick recovery and has been performed on small children. Here, we report our experience with different plication procedures to discuss how to choose among these different plication procedures in endoscopic surgery for pediatric patients with diaphragmatic eventration. PATIENTS AND METHODS We retrospectively analyzed clinical data of 27 pediatric patients (21 boys, 6 girls; median age: 12.7 months, range 2 months-3 years) admitted to our hospital between November 2008 and July 2013. Three different plication procedures were used: the "reefing the mainsail" technique (8 patients), "invaginating the diaphragmatic dome" technique (10 patients), and "pleating" technique (9 patients). Indications included ventilator dependency (7.41 %), respiratory distress (22.22 %), chronic lung lobe collapse (11.11 %), persistent atelectasis with recurrent pneumonias (18.52 %), and asymptomatic severe eventration (40.74 %). RESULTS Descending distance of diaphragm after surgery ranged from 1 to 4.5 intercostal spaces (mean distance: 2.65 intercostal spaces). All patients recovered well postoperatively, except for one patient with a pneumothorax. Two patients who required respiratory support before the operation no longer required it within 7 d after surgery. Follow-up ranged from 1 to 35 months. Clinical results were satisfactory with obvious improvement in symptoms and a slight re-elevation within a distance of one intercostal space. CONCLUSION For pediatric patients with diaphragmatic eventration, different endoscopic surgeries and plication procedures all yielded satisfactory results. We believe that the choice of one procedure over the other depends only on the surgeon's experience.

Abstract
Aim: To evaluate and compare the extent of surgical stress following laparoscopic nephrectomy (LN) and open nephrectomy (ON) in children. Materials and Methods: Twenty consecutive children undergoing nephrectomy were randomized to LN or ON groups. Acid-base balance, blood glucose, acute phase proteins (C-reactive protein [CRP]) and inflammatory markers (interleukin-6 [IL-6]) were measured pre-operatively, as well as 4 and 24 h after surgery. The differences between the two groups were analyzed statistically (significance value for P < 0.05). Results: The overall acid base status was more stable in LN. The fall in pH 4 h after surgery was more in ON (P = 0.440) and the difference in pH in ON 4 h and 24 h post-operatively was statistically significant (P = 0.002). In LN, significant difference was found in the base excess mean pre-surgery (mean –3.280 mEq/L) and 4 h post-surgery (mean –7.480 mEq/L) (P = <0.05), as well as between 4 h and 24 h after surgery (mean –2.660 mEq/L) (P = 0.011). The acute rise in CRP 24 h post-operatively in the ON (88.972 mg/L) was significantly higher when compared to both the pre-operative and 4 h post-operative values (P < 0.05). This rise was however, not statistically significant when compared to the 24 h post-operative value in LN (46.399 mg/L) (P = 0.062). The rise in IL-6, 24 h post-procedure in LN (mean 44.444 pg/ml) was statistically lower than that in the open group (mean 343.333 pg/ml) (P = 0.041). Conclusions: The stable acid-base status and lesser rise of CRP and IL-6 in LN lead to the conclusion that surgical stress caused by LN is less than ON.

Abstract
Objective This study investigated the influence of laparoscopic carbon dioxide (CO2) pneumoperitoneum on neonate circulation and respiration. Methods The study included neonates undergoing elective laparoscopic abdominal surgery. CO2 insufflation pressure was maintained within 8–14 mmHg for pneumoperitoneum creation. Heart rate (HR), mean arterial pressure (MAP), peripheral oxygen saturation (SpO2), partial pressure of end-tidal carbon dioxide ( PETCO2) and maximum inspiratory pressure were monitored continuously. Arterial blood samples were collected: 5 min before pneumoperitoneum creation (baseline); 5, 10, and 20 min after CO2 insufflation; 10 min after CO2 exsufflation; 10 min after surgery. pH, partial pressure of CO2 (PaCO2) and arterial oxygen saturation (SaO2) were also measured. Results Thirty-six neonates were included. HR and MAP significantly increased after pneumoperitoneum creation, then decreased to baseline after CO2 exsufflation. PaCO2 and PETCO2 were significantly higher after pneumoperitoneum creation, whereas pH was significantly lower 20 min after pneumoperitoneum creation compared with baseline. No significant differences were observed in SpO2 and SaO2. Conclusion CO2 pneumoperitoneum had a significant effect on neonatal circulation and respiration, suggesting that the pneumoperitoneal pressure should be limited within a certain range in neonates undergoing laparoscopic surgery.

Abstract
AIMS AND OBJECTIVES: The aim of this study was to assess and present the outcome (initial experience and lessons learnt) of minimally invasive surgery for various indications in neonates and small infants (< 5 kg) at a single medical centre. MATERIALS AND METHODS: A retrospective analysis was performed on 65 patients (age day 2 to 10 months) managed with minimal access surgery (MAS) for various indications, between 2005 and 2010. We analyzed demographic information, procedures, complications, outcomes, and follow-up and overall feasibility of the procedure. RESULTS: No serious complications except one death in congenital diaphragmatic hernia (CDH) (due to other comorbidities) occurred. Intra operative hypercarbia and hypoxia were observed more frequently in thoracoscopic procedures. Intra operative hypothermia was not common and was well tolerated. Conversion to open procedure (n = 5), post operative ileus (n = 3), port site infection (n = 5) were other complications. CONCLUSION: MAS in neonates and small infants is a technically demanding but a feasible choice available. Some prior experience in older children is required for safe and effective outcome. Good quality optics, video equipments and instruments are required for safe and effective procedure. Intra operative measurement of oxygen saturation and temperature, and diligent post operative ICU care are mandatory for safe and successful outcome.

Abstract
OBJECTIVE To compare thoracic and abdominal cavity volumes during abdominal CO2 insufflation and abdominal wall lift (AWL) conditions. STUDY DESIGN In vitro cadaveric study. ANIMALS Mature medium-to-large breed fresh canine cadavers (n = 6). METHODS Each cadaver was imaged with computed tomography (CT) under baseline, abdominal CO2 insufflation, and AWL conditions. Measurements of thoracic and abdominal cavities were performed for each condition using image-analyzing software. Resulting volumes for each cadaver were converted to percent change from baseline to normalize the data. The t-tests were used to compare percent changes of both thoracic and abdominal volumes. RESULTS Thoracic volume significantly decreased from baseline during CO2 insufflation (P < .01). No significant difference in thoracic volume occurred with AWL when compared with baseline. Abdominal volume increased by 80% with CO2 insufflation (95% CI: 56.4-107.0%) but only 25% with AWL (95% CI: 12.3-37.8%). CONCLUSIONS Abdominal CO2 insufflation results in decreased thoracic volume when compared with baseline. AWL preserved thoracic volume similar to baseline. Abdominal volumes achieved with abdominal CO2 insufflation are significantly greater than those attained with AWL.

Abstract
BACKGROUND Laparoscopic Nissen fundoplication (LNF) is considered by some to be superior to open Nissen fundoplication (ONF). To test this hypothesis, we compared early results after LNF and ONF in a randomized trial. METHODS All children accepted for antireflux surgery for gastroesophageal reflux disease were offered enrollment. Ethical approval and parental consent were obtained. Anesthesia, surgical methods, and postoperative treatment were standardized. Patient demographics, length of hospital stay (LOS), and complications occurring the first 30 postoperative days were registered. RESULTS Eighty-eight children were randomized to LNF (n = 44) or ONF (n = 44). The groups were comparable with regard to age, weight, and comorbidity. Duration of surgery was 150 ± 34 minutes for LNF and 89 ± 25 minutes for ONF (P < .001). Median LOS was 7.0 days (range, 3-57 days) and 7.5 days (range, 2-20 days) after LNF and ONF, respectively (P = .74). Postoperative complications occurred in 48 patients, 24 in both groups. Twenty-four patients (LNF: n = 12, ONF: n = 11) were readmitted to hospital because of complications occurring after discharge. CONCLUSIONS This study failed to show that LNF is superior to ONF when surgery duration, LOS, and complications occurring during the first postoperative month were compared. Apart from surgery duration, the results were surprisingly similar.

Abstract
BACKGROUND Currently, thoracoscopic surgery is replacing thoracotomy for an ever increasing number of indications, even in pediatric surgery. However, there are few reports describing thoracoscopic plication (TP) for diaphragmatic eventration in children, particularly in neonates. We report a case of TP under single-lung ventilation in a neonate with diaphragmatic eventration. CASE REPORT A 10-day-old boy was referred for surgical management of right diaphragmatic eventration. Birth was at term, following an uncomplicated pregnancy and delivery. Shortness of breath, labored respiration and chest retraction presented soon after birth, necessitating mechanical ventilation. Chest radiography and computed tomography revealed an elevated right hemidiaphragm. Attempted weaning off mechanical ventilation failed with persistence of respiratory symptoms, requiring nasal directional positive airway pressure. However, because there was no resolution of symptoms, TP was performed using a 3 port technique under single-lung ventilation on day 17 of life. The postoperative course was excellent with complete resolution of respiratory symptoms with no recurrence for 9 months. CONCLUSION To the best of our knowledge, this is the youngest case of TP for diaphragmatic eventration performed under single-lung ventilation. TP is safe, effective and minimally invasive and should be considered actively for the treatment of symptomatic diaphragmatic eventration even in neonates.

Abstract
Surgical management of congenital diaphragmatic hernia (CDH) remains a challenge for all clinicians. While the treatment strategies for CDH have evolved from emergent surgical intervention to initial hemodynamic stabilization with delayed surgical repair, surgical innovations have remained limited in the last 20 years. Advances in surgical approaches, such as minimally invasive surgery and alternatives to diaphragmatic replacement, have focused on improvements in surgical morbidity.

Abstract
BACKGROUND/PURPOSE Congenital diaphragmatic hernia (CDH) and esophageal atresia with tracheoesophageal fistula (EA/TOF) can be repaired thoracoscopically, but this may cause hypercapnia, acidosis, and reduced cerebral oxygenation. We evaluated the effect of thoracoscopy in infants on cerebral oxygen saturation (cSO(2)), arterial blood gases, and carbon dioxide (CO(2)) absorption. METHODS Eight infants underwent thoracoscopy (6 CDH and 2 EA/TOF). Serial arterial blood gases were taken. Regional cSO(2) was measured using near-infrared spectroscopy. Absorption of insufflated CO(2) was calculated from exhaled (13)CO(2)/(12)CO(2) ratio measured by mass spectrometry. RESULTS CO(2) absorption increased during thoracoscopy with a maximum 29% ± 6% of exhaled CO(2) originating from the pneumothorax. Paco(2) increased from 9.4 ± 1.3 kPa at the start to 12.4 ± 1.0 intraoperatively and then decreased to 7.6 ± 1.2 kPa at end of operation. Arterial pH decreased from 7.19 ± 0.04 at the start to 7.05 ± 0.04 intraoperatively and then recovered to 7.28 ± 0.06 at end of operation. Cerebral hemoglobin oxygen saturation decreased from 87% ± 4% at the start to 75% ± 5% at end of operation. This had not recovered by 12 (74% ± 4%) or 24 hours (73% ± 3%) postoperatively. CONCLUSIONS This preliminary study suggests that thoracoscopic repair of CDH and EA/TOF may be associated with acidosis and decreased cSO(2). The effects of these phenomena on future brain development are unknown.

Abstract
Background: Pediatric laparoscopy (LS) is claimed to be superior to open surgery (OS). This review questions the scientific veracity of this assertion by systematic analysis of published evidences comparing LS versus OS in infants and children. Materials and Methods: Search of PubMed data base and the available literature on pediatric LS is analyzed. Results: One hundred and eight articles out of a total of 426 papers were studied in detail. Conclusions: High quality evidences indicate that LS is, at the best, as invasive as OS; and is at the worst, more invasive than conventional surgery. There are no high quality evidences to suggest that LS is minimally invasive, economically profitable and is associated with fewer complications than OS. Evidences are equally distributed for and against the benefits of LS regarding postoperative pain. Proof of cosmetic superiority of LS or otherwise is not available. The author concludes that pediatric laparoscopy, at the best, is simply comparable to laparotomy and its superiority over the latter could not be sustained on the basis of available scientific evidences. Benefits of laparoscopy appear to recede with younger age. Concerns are raised on the quick adoption, undue promotion and frequent misuse of laparoscopy in children.

Abstract
OBJECTIVE To compare the effects of surgery on energy and protein metabolism in children randomized to undergo laparoscopic and open surgery. STUDY DESIGN We randomized 41 patients to open or laparoscopic Nissen fundoplication. Anesthesia and postoperative management were standardized. We recorded core temperature, respiratory gas exchange preoperatively, intraoperatively, and 4 and 24 hours postoperatively and calculated resting energy expenditure (REE). Protein breakdown was measured by using stable isotopic leucine infusion preoperatively and 4 hours postoperatively. RESULTS Intraoperative core temperature and oxygen consumption increased in the laparoscopic group compared with the open group. REE decreased in the early postoperative period in the open group, but did not decrease after laparoscopy. REE at 4 hours was higher after laparoscopy. Protein breakdown also decreased in the early postoperative period; the pattern of change between open and laparoscopic groups was of borderline significance. CONCLUSIONS Laparoscopy in children may alter the changes in energy metabolism observed after open surgery. These differences may be partially caused by alterations in intraoperative thermoregulation and protein breakdown during laparoscopy in children.

Abstract
Background The purpose of this study was to assess the safety issues concerning anesthetic management of video-assisted thoracoscopic surgery (VATS) in pediatric patients. Methods The medical records of 52 pediatric patients undergoing VATS using general anesthesia and one-lung ventilation (OLV) were reviewed. OLV was achieved with a Fogarty catheter (n = 23) or endobronchial intubation (n = 7) in patients < 10 years of age (group Y, n = 30), and using a double-lumen tube (n = 19) or a univent (n = 3) in children aged between 10 and 16 years of age (group O, n = 22). Hypoxemia, hypercarbia, the difference between ETCO2 and PaCO2, and the effect of CO2 insufflation were assessed. Results A decrease in SpO2 less than 90% was observed in 40% of the group Y, compared to none of the group O (P < 0.05). A hypercarbia (ETCO2 > 50 mmHg) was observed more frequently in group Y (40%) than in group O (0%; P < 0.05). The difference between the ETCO2 and PaCO2 was 10.4 ± 8.9 mmHg in group Y and 4.6 ± 3.9 mmHg in group O (P < 0.05). Hypercarbia and acidosis occurred more frequently in patients with CO2 insufflation than those without insufflation in group Y. Conclusions Although the anesthesia for VATS in pediatric patients was successfully accomplished, the infants and younger children presented with more intra-operative problems when compared with older children. The anesthetic management for VATS in infants and younger children requires careful and vigilant monitoring.

Abstract
INTRODUCTION Thoracoscopic repair of congenital diaphragmatic hernia (CDH) has been described, but its efficacy and safety have not been validated. The aim was to compare our experience of thoracoscopy with laparotomy repair. METHODS After ethics approval, we reviewed the notes of neonates with CDH operated in our institution between 2003 and 2008. Two historical groups were compared: infants who underwent laparotomy (2003-2008) or thoracoscopy (2007-2008). Data were compared by t test or Mann-Whitney tests. RESULTS Thirty-five children had open repair of CDH, and 13 had thoracoscopic repair. Groups were homogeneous for age and weight. Five (38%) neonates who had thoracoscopy were converted to open for surgical difficulties (n = 4) and O(2) desaturation (n = 1). Patch repair was used in 12 (34%) open and 6 (46%) thoracoscopic repairs. End-tidal CO(2) was significantly elevated during thoracoscopy, but this was not reflected in arterial CO(2) or pH. There were 3 (8%) recurrences after open repair and 2 (25%) after thoracoscopy (P = .19). CONCLUSION Thoracoscopic repair of CDH is feasible. Arterial blood gases should be closely monitored. Despite higher EtCO(2), conversion to open was mainly because of difficult repair. A randomized trial is necessary to assess the effect of thoracoscopy on ventilation and recurrences.

Abstract
Cornelia de Lange syndrome involves multiple malformations with particular phenotypic features (craniofacial abnormalities such as microcephaly or hypertrichosis with synophrys; cutaneous abnormalities such as hirsutism, and limb anomalies) and it is associated with a high percentage of mental retardation and complications such as digestive tract abnormalities, cardiac defects, and endocrine disorders. We report the case of a 2-month-old infant girl who underwent a laparoscopic antireflux procedure, with closure of a diaphragmatic hernia and a gastric stoma. The medical history included repeated episodes of aspiration pneumonia and hypertension. Early in the procedure, 2 episodes of sudden desaturation, hypotension, and bradycardia with a probable diagnosis of air embolism. The complications resolved with specific treatment. Anesthetic management for laparoscopic surgery in these patients is truly complex and must be informed by a thorough understanding of the disease and complications that may develop.

Abstract
The aim of this paper is to review the factors which may affect breath (13)CO(2)/(12)CO(2) natural abundance in patients undergoing surgery or intensive care. Intravenous glucose administration is a major determinant of the (13)CO(2)/(12)CO(2) of breath as intravenous glucose preparations are almost all derived from cornstarch. In addition, the oxidation of endogenous substrates can affect the (13)CO(2)/(12)CO(2) ratio. During many endoscopic procedures, such as laparoscopic surgery, carbon dioxide insufflation is used to provide a working space. As medical CO(2) is relatively depleted in (13)CO(2) compared with endogenous and exogenous metabolic CO(2) sources, breath (13)CO(2)/(12)CO(2) measurements can be used to estimate CO(2) absorption during these procedures. However, all these factors may also be affected by the bicarbonate pool, making a definitive attribution of changes in breath (13)CO(2)/(12)CO(2) to a single factor problematic.

Abstract
The knowledge on the physiological impact of endoscopic surgery in infants and children is limited. Cardiovascular effects of pneumoperitoneum are mainly the result of an increase in intraabdominal pressure, absorption of carbon dioxide, and a stimulation of the neurohumoral vasoactive system. In infants, pneumoperitoneum alters the heart rate, mean arterial pressure, left ventricular endsystolic and end-diastolic volume, and meridional wall stress. Urine production is significantly reduced, and cerebral oxygenation and blood flow are altered. However, postoperative immune function is preserved or restored faster, and specific physiological responses to endoscopic surgery are well tolerated by otherwise healthy infants and children. The effects in children with specific conditions, such as sepsis, cancer, or organ dysfunction, remain to be investigated.

Abstract
Pneumoperitoneum (PN) and the gas used to insufflate the abdominal cavity during laparoscopy seem to be responsible for local and systemic modifications. The aim of this study was to verify the effects of intra-abdominal carbon dioxide (CO(2)) and air insufflation on the peritoneum, as well as the cortico-surrenal response in prepuberal rats. Sixty prepuberal rats were divided into three groups: in the first (S, n = 36), PN was induced with CO(2), whereas in the second (A, n = 14), it was induced with filtered room air; in both conditions, insufflation lasted 30 min at a pressure of 10-12 mmHg. The third group (C, n = 10), underwent general anesthesia only. Two hours after inducing anaesthesia, 12 rats in group S, 6 in group A and 6 in group C were killed and the remaining, after 24 h; specimens of the visceral and the parietal peritoneum were obtained for histological examination, blood sample was taken for cortisol and DHEA-S assays at the different study periods. At the histological examination performed 2 h later, the groups S and A presented inflammatory cell infiltrate in the parietal and visceral peritoneum; this finding was even more marked in group A, which presented also congestion, hemorrhage and disruption of the cell line. Twenty-four hours after the experiment, the peritoneum of the two insufflated groups presented chronic infiltrate and reactive mesothelial cells with congestion, which was more evident in group A, but totally absent in group C. Cortisol levels were significantly higher in groups S and A (2.15:1 ratio) killed 2 h later compared to those killed 24 h later and to the control group. DHEA-S levels were not significantly different between the groups. Our results demonstrate that the chemical, physical and molecular impact of CO(2) on the peritoneum causes inflammation and tissue damage, this was even more evident 24 h after our experiment and in the air insufflated group. PN induced a significant variation in blood cortisol levels at 2 h. The CO(2) insufflation should be limited in patients with pre-existing peritoneal damage.

Abstract
BACKGROUND Complex procedures for managing congenital abnormalities are reported to be feasible. However, neonatal videosurgery involves very specific physiologic constraints. This study evaluated the safety and complication rate of videosurgery during the first month of life and sought to determine both the risk factors of perioperative complications and the most recent trends in practice. METHODS From 1993 to 2005, 218 neonates (mean age, 16 days; weight, 3,386 g) from seven European university hospitals were enrolled in a retrospective study. The surgical indications for laparoscopy (n = 204) and thoracoscopy (n = 14) were congenital abnormalities or exploratory procedures. RESULTS Of the 16 surgical incidents that occurred (7.5%), mainly before 2001, 11 were minor (parietal hematoma, eventration). Three neonates had repeat surgery for incomplete treatment of pyloric stenosis. In two cases, the incidents were more threatening (duodenal wound, diaphragmatic artery injury), but without further consequences. No mortality is reported. The 26 anesthetic incidents (12%) that occurred during insufflation included desaturation (<80% despite 100% oxygen ventilation) (n = 8), transient hypotension requiring vascular expansion (n = 7), hypercapnia (>45 mmHg) (n = 5), hypothermia (<34.9 degrees C) (n = 4), and metabolic acidosis (n = 2). The insufflation had to be stopped in 7% of the cases (transiently in 9 cases, definitively in 6 cases). The significant risk factors for an incident (p < 0.05) were young age of the patient, low body temperature, thoracic insufflation, high pressure and flow of insufflation, and length of surgery. CONCLUSION Despite advances in miniaturizing of instruments and growth in surgeons' experience, the morbidity of neonatal videosurgery is not negligible. A profile of the patient at risk for an insufflation-related incident emerged from this study and may help in the selection of neonates who will benefit most from these techniques in conditions of maximal safety.

Abstract
BACKGROUND Carbon dioxide (CO(2)) is absorbed during pneumoperitoneum and may cause adverse haemodynamic effects. The aim of this study was to measure the elimination of exogenous CO(2) during laparoscopy in children. METHODS Ten children [27.6 (56.5) months; mean (SD)] undergoing laparoscopic and nine [24.5 (17.3) months] undergoing open surgery were studied. Breath samples were collected at the line for end-tidal CO(2) and analysed for (13)CO(2)/(12)CO(2) ratio expressed as deltaPDB (difference from standard), by isotope-ratio mass spectrometry. The proportion of absorbed CO(2) was calculated comparing exhaled (13)CO(2)/(12)CO(2) before and during CO(2) pneumoperitoneum. RESULTS (13)CO(2)/(12)CO(2) in medical CO(2) was -32.7 (2.1) deltaPDB. (13)CO(2)/(12)CO(2) in breath of patients undergoing open procedures was -24.3 (2.4) deltaPDB at the start of operation and did not change during the operation (P > 0.2). (13)CO(2)/(12)CO(2) in breath of patients undergoing laparoscopy was -21.5 (5.4) deltaPDB at the start of insufflation, and decreased during pneumoperitoneum by 2.5 (1.6) deltaPDB, indicating absorption of exogenous CO(2). The percentage of expired CO(2) absorbed rose to 15.5 (7.7)% after 30 min of pneumoperitoneum and decreased rapidly after desufflation. CONCLUSION After 10 min of laparoscopy 10-20% of expired CO(2) derives from the exogenous CO(2). CO(2) absorption can be measured using a simple mass spectrometric technique.

Abstract
A retrospective analysis comparing intraoperative physiological variables during laparoscopic and open pyloromyotomies was undertaken during an 18-month period at our institution. Fifty cases were examined (22 laparocopic and 28 open). Operative time, temperature change, end-tidal CO2, heart rate, and blood pressure were examined and compared. No significant differences were found in operative time, temperature change, heart rate, and blood pressure. As anticipated, in laparoscopic procedures there was a statistically significant increase in end-tidal CO2, although none of the end-tidal CO2 values rose above 6 kPa. It is concluded that laparoscopic pyloromyotomies undertaken in small infants with insufflation pressures of 8-10 mm Hg are without significant adverse physiological effects and are no slower to perform than open procedures.

Abstract
OBJECTIVES Video-surgery in neonates is recent. Data on the respiratory, hemodynamic, and thermic effects during the first month of life are still sparse. This study aimed to evaluate the tolerance of video-surgery in neonates and to determine the risk factors of per-operative complications. METHODS From 1994 to 2004, 49 neonates (mean age: 11 days; weight: 3285 g) underwent 50 video-surgical procedures. Indications for laparoscopy were duodenal atresias, volvulus with malrotation, pyloric stenosis, gastroesophageal reflux, cystic lymphangiomas, ovarian cysts, biliary atresia, and congenital diaphragmatic hernias; indications for thoracoscopy were esophageal atresias and tracheoesophageal fistula. RESULTS Median operative time was 79 minutes. Mean insufflation pressure was 6.7 mm Hg (range: 3-13). Oxygen saturation decreased, especially with thoracic insufflation or high-pressure pneumoperitoneum. Systolic arterial pressure, which decreased in 20% of the patients, was controlled easily with vascular expansion. Thermic loss (mean postoperative temperature: 35.6 degrees C) was proportional to the duration of insufflation. No surgical incident was noted. Ten anesthetic incidents occurred (20%), 3 of which required temporary or definitive interruption of insufflation (O2 saturation <70%). Risk factors for an incident were low preoperative temperature, high variation of end-tidal pressure of CO2, surgical time >100 minutes, thoracic insufflation, and a high oxygen or vascular expansion requirement at the beginning of insufflation. CONCLUSION The neonate's high sensitivity to insufflation is an important limiting factor of video-surgery. The described profile of the neonate at risk may help to reduce the frequency of adverse effects of this technique and improve its tolerance.

Abstract
Gastro-esophageal reflux (GER) is a physiological process characterized by the involuntary passage of gastric contents into the lower esophagus not induced by noxious stimuli. It represents a common condition in preterm infants and may occur in healthy neonates. The phenomenon is only considered as GER disease when it causes the patient to be symptomatic or results in pathological complications. Fundoplication is recommended in symptomatic neonates and infants with GER that does not respond to medical treatment. The presence of respiratory symptoms related to GER is the primary indication for fundoplication in this selected population. The Nissen fundoplication is the antireflux procedure of choice and the experience concerning other procedures, including laparoscopic techniques, is limited in this age group. The best results are achieved in newborn infants with isolated GER, as the recurrence rate of GER in infants with associated anomalies is high. Further studies are necessary to evaluate the benefit of laparoscopic fundoplication in this age group.
