Italian multicenter survey on laparoscopic treatment of gastro-esophageal reflux disease in children

Outcomes of fundoplication for paediatric gastroesophageal reflux disease

PURPOSE

Outcomes of fundoplication in children.

METHODS

In this monocentric retrospective study, chart review was performed on children who underwent fundoplication between 2006 and 2013. Outcomes were defined as the need for redo fundoplication and recommencement of anti-reflux medication (ARM) at 6-month follow-up.

RESULTS

119 patients underwent fundoplication with a mean age of 4.76 years and 55.5% of these were male. At 6-month follow-up, 21 (17.6%) required redo fundoplication and 64 (53.8%) were recommenced on ARM. Post-operative complications occurred in 50 (42.2%) of children; 30% of those with complications had surgery at less than 1 year of age, and 36% had an associated comorbid condition. Neither being under the age of one nor associated comorbidity was significantly associated with a poor outcome. Concurrent gastrostomy was associated with a higher risk of being back on ARM at 6-month follow-up (p = 0.003). Neither gastrointestinal or respiratory symptoms pre-surgery nor abnormal pre-operative investigations including pH monitoring and endoscopy were predictive of poor outcome post-fundoplication.

CONCLUSION

Although fundoplication has a role in the treatment of severe GORD in children, the majority of children in this study needed to restart their anti-reflux medications within 6 months of surgery.

Esophagogastric dissociation reduces the re-operation rate for persistent gastroesophageal reflux in severely neurologically impaired children

PURPOSE

In this study we want to demonstrate the effectiveness of the esophagogastric dissociation as a first level operation in treatment of the gastroesophageal reflux in severe neurologically impaired children, in term of a reduction of reoperation rate.

METHODS

We divided patients operated from 1998 to 2005 in a group A, composed by children treated with fundoplication, and in a group AR, composed by the patients of group A who had a recurrence of reflux and that was treated with esophagogastric dissociation. Patients operated from 2005 to 2013 were selected on the basis of the severity of the neurological impairment and were divided in a group B, treated with fundoplication, and in a group C of more severe impaired children, treated with esophagogastric dissociation. Data regarding the complications of the A and C groups were analyzed with Fisher's test.

RESULTS

We evaluated 63 patients: 34 (54%) in group A, 11 in group AR, 15 (23.6%) in group B, 14 (22.4%) in group C. The Fisher's test showed a non significant difference with a p value of 0.2.

CONCLUSION

Despite of statistic result we believe that TOGD is a useful procedure as the first choice of surgical management in severe neurological impaired children affected by gastroesophageal reflux.

Advances in minimally invasive surgery in pediatric patients

Surgery has changed dramatically over the last several decades. The emergence of MIS has allowed pediatric surgeons to manage critically ill neonates, children, and adolescents with improved outcomes in pain, postoperative course, cosmesis, and return to normal activity. Procedures that were once thought to be too difficult to attempt or even contraindicated in pediatric patients in many instances are now the standard of care. New and emerging techniques, such as single-incision laparoscopy, endoscopy-assisted surgery, robotic surgery, and techniques yet to be developed, all hold and reveal the potential for even further advancement in the management of these patients. The future of MIS in pediatrics is exciting; as long as our primary focus remains centered on developing techniques that limit morbidity and maximize positive outcomes for young patients and their families, the possibilities are both promising and infinite.

Outcomes of pediatric laparoscopic fundoplication: a critical review of the literature

BACKGROUND/OBJECTIVE

Laparoscopic fundoplication for gastroesophageal reflux disease (GERD) is one of the most common procedures performed in children. A critical literature review was performed to evaluate the level and quality of evidence supporting the efficacy of this procedure.

METHODS

Systematic reviews of the EMBASE, PubMed and CENTRAL databases were conducted to retrieve all articles published over a 15-year period (1996 to 2010) reporting medium- to long-term outcomes (minimum six months follow-up) of laparoscopic fundoplication for the treatment of pediatric GERD. Articles were critically appraised using the Newcastle-Ottawa quality assessment scale and the Cochrane risk of bias assessment tool. Extracted outcomes included GERD recurrence, need for reoperation, postoperative morbidity and mortality.

RESULTS

A total of 5302 articles were retrieved. Thirty-six studies met inclusion and exclusion criteria, including five prospective (level 2b), four retrospective comparative (level 3b) and 27 case series (level 4). No studies compared laparoscopic fundoplication with medical treatment. Thirty-six per cent of studies did not describe the symptoms used to suspect GERD; 11% did not disclose the diagnostic modalities used; and 41% did not report the findings of diagnostic modalities. Only 17% of studies provided a definition of recurrence, and only 14% attempted to control for confounding variables. The follow-up intervals were inconsistently reported, ranging between two months and nine years. Significant heterogeneity among studies limited the ability to pool outcomes. Mean (± SD) recurrence rates varied between 0% and 48±19.6% of patients. Reoperation was required in 0.69±0.95% to 17.7±8.4% of patients. Mortality ranged between 0% and 24±16.7%.

CONCLUSION

The level and quality of the evidence supporting laparoscopic fundoplication are extremely poor. Higher-quality data are required before the procedure can be considered to be an effective intervention in the treatment of pediatric GERD.

Surgical management of pediatric gastroesophageal reflux disease

Gastroesophageal reflux (GER) is common in the pediatric population. Most cases represent physiologic GER and as the lower esophageal sphincter (LES) matures and a solid diet is introduced, many of these patients (>65%) experience spontaneous resolution of symptoms by two years of age. Those who continue to have symptoms and develop complications such as failure to thrive, secondary respiratory disease, and others are classified as having gastroesophageal reflux disease (GERD). Goals of GERD treatment include the resolution of symptoms and prevention of complications. Treatment options to achieve these goals include dietary or behavioral modifications, pharmacologic intervention, and surgical therapy. This paper will review the clinical presentation of GERD and discuss options for surgical management and outcomes in these patients.

The effects and efficacy of antireflux surgery in children with gastroesophageal reflux disease: a systematic review

BACKGROUND

Antireflux surgery (ARS) for gastroesophageal reflux disease (GERD) is one of the most frequently performed major operations in children. Many studies have described the results of ARS in children, however, with a wide difference in outcome. This study aims to systematically review the efficacy of pediatric ARS and its effects on gastroesophageal function, as measured by gastroesophageal function tests. This is the first systematic review comprising only prospective, longitudinal studies, minimizing the risk of bias.

METHODS

Three electronic databases (Medline, Embase, and the Cochrane Library) were searched for prospective studies reporting on ARS in children with GERD.

RESULTS

In total, 17 eligible studies were identified, reporting on a total of 1,280 children. The median success rate after ARS was 86% (57-100%). The success rate in neurologically impaired children was worse in one study, but similar in another study compared to normally developed children. Different surgical techniques (total versus partial fundoplication, or laparoscopic versus open approach) showed similar reflux recurrence rates. However, less postoperative dysphagia was observed after partial fundoplication and laparoscopic ARS was associated with less pain medication and a shorter hospital stay. Complications of ARS varied from minimal postoperative complications to severe dysphagia and gas bloating. The reflux index (RI), obtained by 24-h pH monitoring (n = 8) decreased after ARS. Manometry, as done in three studies, showed no increase in lower esophageal sphincter pressure after ARS. Gastric emptying (n = 3) was reported either unchanged or accelerated after ARS. No studies reported on barium swallow x-ray, endoscopy, or multichannel intraluminal impedance monitoring before and after ARS.

CONCLUSION

ARS in children shows a good overall success rate (median 86%) in terms of complete relief of symptoms. Efficacy of ARS in neurologically impaired children may be similar to normally developed children. The outcome of ARS does not seem to be influenced by different surgical techniques, although postoperative dysphagia may occur less after partial fundoplication. However, these conclusions are bound by the lack of high-quality prospective studies on pediatric ARS. Similar studies on the effects of pediatric ARS on gastroesophageal function are also very limited. We recommend consistent use of standardized assessment tests to clarify the effects of ARS on gastroesophageal function and to identify possible risk factors for failure of ARS in children.

Laparoscopic Nissen fundoplication in infants and children: analysis of 106 consecutive patients with special emphasis in neurologically impaired vs. neurologically normal patients

BACKGROUND

The laparoscopic Nissen fundoplication has become a frequently performed procedure in infants and children who suffer from gastroesophageal reflux disease (GERD). In this study we describe our 8-year experience with 106 consecutive laparoscopic Nissen fundoplications.

METHODS

From January 1994 to May 2002, we included 106 consecutive patients (57 neurologically normal (NN) and 49 neurologically impaired (NI)). The indications were symptomatic GERD, pulmonary symptoms or a combination of both. Patient's outcome was assessed by symptom evaluation, technical examinations and a questionnaire.

RESULTS

Mortality was 0% and conversion rate was 2.8%. Major postoperative complications occurred in 12 patients, mostly neurologically impairment. Dysphagia occurred in 23 patients of which 4 required dilatations and 2 a redo Nissen. Gas bloating occurred in 15 children, with spontaneous regression in all. Recurrent pneumopathies were seen in four children. Documented recurrence of reflux occurred in three symptomatic patients. Redo laparoscopic surgery was performed in six patients. A questionnaire was sent to each patient's parents. This showed that most patients had a normal or clearly improved quality of life (93.1% NN, 90.5% NI). Most patients were satisfied with the result and up to 39.5% gave a maximum satisfaction score.

CONCLUSION

The laparoscopic Nissen fundoplication can safely be performed with a low conversion rate and no surgical mortality in neurologically normal and neurologically impaired children. Neurologically impaired children are more susceptible to per- and postoperative complications. A good quality of life and a high index of satisfaction could be achieved in most patients.

Long-term outcome of laparoscopic Nissen, Toupet, and Thal antireflux procedures for neurologically normal children with gastroesophageal reflux disease

BACKGROUND

Nissen fundoplication is the most popular laparoscopic operation for the management of gastroesophageal reflux disease (GERD). Partial fundoplications seem to be associated with a lower incidence of postoperative dysphagia, and thus a better quality of life for patients. The aim of this study was to compare the long-term outcome in neurologically normal children who underwent laparoscopic Nissen, Toupet, or Thal procedures in three European centers with a large experience in laparoscopic antireflux procedures.

METHODS

This study retrospectively analyzed the data of 300 consecutive patients with GERD who underwent laparoscopic surgery. The first 100 cases were recorded for each team, with the first team using the Toupet, the second team using the Thal, and the third team using the Nissen procedure. The only exclusion criteria for this study was neurologic impairment. For this reason, 66 neurologically impaired children (52 Thal, 10 Nissen, 4 Toupet) were excluded from the study. This evaluation focuses on the data for the remaining 238 neurologically normal children. The patients varied in age from 5 months to 16 years (median, 58 months). The median weight was 20 kg. All the children underwent a complete preoperative workup, and all had well-documented GERD. The position of the trocars and the dissection phase were similar in all the procedures, as was the posterior approximation of the crura. The short gastric vessels were divided in only six patients (2.5%). The only difference in the surgical procedures was the type of antireflux valve created.

RESULTS

The median duration of surgery was 70 min. There was no mortality and no conversion in this series. A total of 12 (5%) intraoperative complications (5 Nissen, 5 Toupet, 2 Thal) and 13 (5.4%) postoperative complications (3 Toupet, 4 Nissen, 6 Thal) were recorded. Only six (2.5%) redo procedures (2 Thal, 2 Toupet, 2 Nissen) were performed. After a minimum follow-up period of 5 years, all the children were free of symptoms except nine (3.7%), who sometimes still require medication. The incidence of complications and redo surgery for the three procedures analyzed with the Mann-Whitney U test are not statistically significant.

CONCLUSIONS

For pediatric patients with GERD, laparoscopic Nissen, Toupet, and Thal antireflux procedures yielded satisfactory results, and none of the approaches led to increased dysphagia. The 5% rate for intraoperative complications seems linked to the learning curve period. The authors consider the three procedures as extremely effective for the treatment of children with GERD, and they believe that the choice of one procedure over the other depends only on the surgeon's experience. Parental satisfaction with laparoscopic treatment was very high in all the three series.
