In the past decade, mortality was primarily the result of associated diseases, and operative morbidity had greatly improved. Yet the consequences of opening the thoracic cavity remained unchanged. In the era of endoscopic surgery, a thoracic approach to EA has become feasible, but is it of benefit for the patient? Methods: Between May 2000 and June 2002, 13 neonates underwent thoracoscopic repair of EA. There were 12 boys and 1 girl. Mean gestational age was 36.9 weeks. Mean weight was 3093 g. Eleven children had associated anomalies. Results: All of the procedures were performed thoracoscopically. There were no intraoperative complications, although anastomosis was difficult in one patient due to an extensive distance between the two stumps. Mean operating time was 2.6 h (range, 1.45–3.5). Five short-term postoperative complications occurred. Four of the early patients had stenosis due to a too-small incision in the proximal pouch, which needed one or more dilatations. One of these children, as well together as one other child, had anastomotic leakage, which was treated conservatively. Late complications consisted of gastroesophageal reflux (n = 5) and tracheomalacia (n = 1); these conditions required endoscopic correction in, respectively, two and one cases. Feeding by nasogastric tube was started after 3.5 days (mean), and total oral feeding was possible after 8.6 days (mean). Mean hospitalization was 12.2 days. Mean follow-up was 15.2 months. Scar formation was minimal, and the thoracic cage was preserved. Conclusion: The feasibility of thoracoscopic repair of EA has already been demonstrated. Today, its results in terms of operating time, feeding, hospital stay, and postoperative complications are equal to open procedures. Its advantages include better cosmesis and preservation of the thorax.

Methods: A retrospective study of all neonates who had undergone an MAS procedure between 1993 and August 2002 was conducted. Patients with associated cardiac anomalies were selected, and their charts were studied by a pediatric cardiologist, anesthesiologist, and surgeon. Results: A total of 171 neonates underwent an MAS procedure. Twenty of the neonates had 22 associated cardiac anomalies. MAS was not contraindicated in any case. The intraoperative charts showed no complications or adverse effects of CO 2 insufflation. The postoperative courses were uncomplicated. Conclusion: Apart from duct-dependent lesions, most cardiac anomalies are compatible with safe extracardiac MAS in neonates and young infants.

The purpose of this study was to compare the results of bowel resection with primary anastomosis with the results of bowel resection with enterostomy. Sixtythree neonates with NEC had a bowel resection in the acute phase of the disease in the period between February 1990 and March 2001. Thirty-four of them (54%) underwent resection of the bowel with primary anastomosis (Group A), and 29 (46%) had resection with enterostomy (Group B). Group A had a lower gestational age and lower birth weight. Mortality, complication rate, and postoperative weight gain were not significantly different between the groups. However, Group B had a significantly longer primary hospital stay (80±49 days versus 58±31 days, P<0.04) and needed a 2nd hospital stay for restoring gastrointestinal continuity. For both reasons, it can be argued that primary anastomosis is superior to enterostomy after resection.

A retrospective review was conducted of all patients, receiving a PEG in the period January 1993 through December 1997. Patients&amp;#39; characteristics including underlying disease, indications, results of preoperative screening, and complications were recorded. PEG placement was performed with the Seldinger technique and, in some cases, under laparoscopic control. In the event of a pathologic pH study during preoperative screening, laparoscopic antireflux surgery (ARS) was added. Mean age was 5 years and 10 months. The majority of the children were mentally retarded. The main indications for PEG were vomiting, food refusal, inability to swallow, and aspiration. Fifty-nine patients had PEG without ARS. Nineteen of these patients had concomitant laparoscopy. Thirty-seven patients had PEG with ARS. One patient died postoperatively of gastric leakage. PEG-related complications occurred in 31% of the patients. There was a significant higher incidence of complications in the group of patients that underwent ARS together with PEG compared with PEG placement without ARS. Roughly half of the complications were peristomal infection related to the use of T-fasteners and the other half gastroduodenal obstruction caused by the balloon of the gastrostomy catheter, both preventable complications. Preoperative vomiting without a positive pH-study disappeared in most cases after PEG placement. Although the pH study normalized in 34 of 37 patients after concomitant ARS, vomiting persisted in 7 of 17 patients. PEG improved the nutritional status in 75% of the children. PEG improved the nutritional status in the majority of the children. However, PEG placement can lead to a considerable amount of complications, especially when combined with ARS. ARS together with PEG is successful in treating GER but does not necessarily cure preexistent vomiting. PEG alone cures vomiting in 80% of the patients and rarely leads to vomiting. There seems no good reason for combining PEG with ARS. Only if symptoms progress after PEG, ARS should be considered. Caretakers and patients should be well informed before placement.

Type B atresia is seen in 0%–3% and type D atresia in 0.25%–7.7%. In the past 16 years 149 children with esophageal atresia have been treated in the Department of Pediatric Surgery of the University Hospital in Nijmegen. Only 2% and 4% had type B and type D esophageal atresia respectively. There were no routine preoperative contrast studies in this series. There was only a slight increase in morbidity in these patients due to a delay in diagnosing the proximal fistula. Routine preoperative contrast studies are not only time-consuming, but also do not guarantee visualization of the fistula, and the risk of contrast pneumonia always remains. Weighing the pros and cons of these observations, we think it unnecessary to perform extensive routine preoperative contrast studies in all patients with esophageal atresia. Contrast studies should be performed on clinical suspicion of a proximal fistula and should always be performed in close co-operation with an experienced pediatric radiologist. The proximal fistula can best be closed via a cervical incision.

Examples include intestinal malrotation, intestinal atresia, meconium ileus, intestinal aganglionosis, omphaloenteric remnants, and intestinal duplication anomalies. Acquired causes of intestinal obstruction include incarcerated inguinal hernia, intussusception, and inflammatory strictures from necrotizing enterocolitis (Holcomb 1997).

Usually, in conventional open surgery, the thoracic approach is better for right-sided diseases because the liver is in the way if a transabdominal approach is used; a transabdominal approach is preferred for anterior and left-sided conditions. Even after the recent advances in endoscopic surgery, this rule has not been changed or superseded. The thoracoscopic approach has been described for the diagnosis and treatment of right-sided diaphragmatic disorders (Yamashita et al. 1996). We present here the laparoscopic approach for anterior and left-sided diaphragmatic disorders in children, such as congenital or traumatic hernia or eventration.

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.
