Risks and benefits of surgical management of gastroesophageal reflux in neurologically impaired children

Impact of previous abdominal surgery on the outcome of fundoplication for medically refractory gastroesophageal reflux disease in children and young adults

Importance

Fundoplication (FP) is a well-established surgical treatment for gastroesophageal reflux disease (GERD) refractory to medical therapy in children and young adults. During FP, previous abdominal surgery (PAS) can impair the patient’s outcome by causing technical difficulties and increasing intra- and postoperative complication rates.

Objective

The aim of this study was to determine the impact of PAS on the short- and long-term outcome following FP for refractory GERD in a cohort of patients aged < 23 years.

Methods

We retrospectively analyzed 182 patients undergoing a total of 201 FP procedures performed at our university center for pediatric surgery from February 1999 to October 2019. Pre-, intra-, and postoperative variables were recorded and their impact on the rate of intraoperative complications and revision FP (reFP) was analyzed.

Results

A total of 201 FP procedures were performed on 182 patients: 119 (59.2%) as Thal-FP (180° anterior wrap) and 82 (40.8%) as Nissen-FP (360°circular wrap; 67.2% laparoscopic, 32.8% open, 8.9% conversion). The presence of PAS (95 cases, 47.3%) was associated with significantly longer operative times for FP (153.4 ± 53.7 vs.126.1 ± 56.4 min, p = 0.001) and significantly longer hospital stays (10.0 ± 7.0 vs. 7.0 ± 4.0 days, p < 0.001), while the rates of intraoperative surgical complications (1.1% vs. 1.9%, p = 1.000) and the rate re-FP in the long term (8.4% vs. 15.1%, p = 0.19) during a follow-up period of 53.4 ± 44.5 months were comparable to the group without PAS.

Conclusion

In cases of PAS in children and young adults, FP for refractory GERD might necessitate longer operative times and longer hospital stays but can be performed with surgery-related short- and long-term complication rates comparable to cases without PAS.

Perioperative outcomes of laparoscopic fundoplication for gastroesophageal reflux disease in children with or without scoliosis

PURPOSE

This study aimed to evaluate the perioperative outcomes of laparoscopic fundoplication (LF) for gastroesophageal reflux disease (GERD) in children with scoliosis.

METHODS

Data of consecutive patients with GERD who underwent LF from January 2015 to December 2020 at a single pediatric institution were retrospectively analyzed.

RESULTS

Eighty-two patients underwent laparoscopic Nissen fundoplication. The median [interquartile range (IQR)] body weight was 9.3 [7; 14] kg. Seventy-five patients were neurologically impaired (91%), and other comorbidities included scoliosis (n = 33), lung disease (n = 39), and cardiac disease (n = 14). The median (IQR) operative time including the creation of the gastrostomy and volume of bleeding were 160 [143; 190] min and 2 [1; 5] mL, respectively. There were no significant differences between patients with and those without scoliosis (p = 0.17 and p = 0.90, respectively). Patients with cardiac disease had a longer operative time (167 [161; 193] vs. 157 [141; 190] min, p = 0.01). There were three post-operative complications in children with neurological impairment; however, there was no clear relationship between the severity of scoliosis and complications.

CONCLUSION

Severity of scoliosis did not correlate with perioperative results and post-operative complications. This suggests that the same LF technique can be used regardless of the presence or absence of scoliosis in children.

Comparison of laparoscopic Toupet and laparoscopic Nissen fundoplications in neurologically normal children

INTRODUCTION

We compared laparoscopic Toupet fundoplication (LTF) and laparoscopic Nissen fundoplication (LNF) in neurologically normal children.

METHODS

Forty neurologically normal children who were followed up for more than 3 years after LTF (n = 22) or LNF (n = 18) were reviewed retrospectively. LTF and LNF were performed between 2006 and 2012.

RESULTS

There were no significant differences in gender (LTF, 15 male and 7 female patients; LNF:, 12 male and 6 female patients), mean age at surgery (LTF vs LNF: 2.5 vs 2.3 years), mean weight at surgery (LTF vs LNF: 9.6 vs 8.9 kg), preoperative symptoms, preoperative pH monitoring (pH <4) (LTF vs LNF: 26.7% vs 21.8%), mean operative time (LTF vs LNF: 117 vs 126 min), postoperative recommencement of enteral feeding (LTF vs LNF: 3.7 vs 3.8 days), or duration of hospitalization (LTF vs LNF: 5.5 vs 6.3 days). Intraoperative complications were esophageal trauma (LTF; n = 1; 4.5%) and liver trauma (LNF; n = 1; 5.6%) (P = 0.70). Post-LTF complications were wrap stenosis (n = 1; 4.5%), and post-LNF complications were wrap stenosis (n = 1; 5.5%) and gastric outlet obstruction (n = 1; 5.5%) (P = 0.43); all were managed conservatively. No case required conversion to open repair. There was no recurrence after LTF, but there were three cases (16.7%) after LNF (P = 0.08). Reoperation was performed at 4, 11, and 13 months, respectively.

CONCLUSION

Despite LTF and LNF appearing to be equally effective, three LNF cases required reoperation.

Surgical management of gastroesophageal reflux disease (GERD) in children: A systematic review

OBJECTIVE

The goal of this systematic review by the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee was to derive recommendations from the medical literature regarding the surgical treatment of pediatric gastroesophageal reflux disease (GERD).

METHODS

Five questions were addressed by searching the MEDLINE, Cochrane, Embase, Central, and National Guideline Clearinghouse databases using relevant search terms. Consensus recommendations were derived for each question based on the best available evidence.

RESULTS

There was insufficient evidence to formulate recommendations for all questions. Fundoplication does not affect the rate of hospitalization for aspiration pneumonia, apnea, or reflux-related symptoms. Fundoplication is effective in reducing all parameters of esophageal acid exposure without altering esophageal motility. Laparoscopic fundoplication may be comparable to open fundoplication with regard to short-term clinical outcomes. Partial fundoplication and complete fundoplication are comparable in effectiveness for subjective control of GERD. Fundoplication may benefit GERD patients with asthma, but may not improve outcomes in patients with neurologic impairment or esophageal atresia. Overall GERD recurrence rates are likely below 20%.

CONCLUSIONS

High-quality evidence is lacking regarding the surgical management of GERD in the pediatric population. Definitive conclusions regarding the effectiveness of fundoplication are limited by patient heterogeneity and lack of a standardized outcomes reporting framework.

TYPE OF STUDY

Systematic review of level 1-4 studies.

LEVEL OF EVIDENCE

Level 1-4 (mainly level 3-4).

Unilateral versus bilateral wrap crural fixation in laparoscopic Nissen fundoplication for children

Introduction:

Gastroesophageal reflux (GERD) is common in neurologically impaired (NI) children. Fundoplication and gastrostomy have previously been indicated in NI children with GERD who have not responded to medical treatment. The most common reason for fundoplication failure is intrathoracic migration of the wrap.

Objective:

The aim of the study is to measure the effect of wrap fixation on the final outcome of laparoscopic Nissen fundoplication in NI children.

Patients and Methods:

A retrospective file review was conducted for all NI children who underwent laparoscopic Nissen fundoplication in 2 tertiary pediatric surgery centers in the United Arab Emirates from February 15, 2006 to February 15, 2013. Redo fundoplication patients were excluded from the study. Patients were divided into 2 groups: group 1 in which the fundoplication wrap was fixed to the right crus only, and group 2 in which the wrap was fixed to the right and left crus simultaneously.

Results:

The study population included 68 patients; there were 47 male and 21 female children. Mean age at time of surgery was 8.2 years. Recurrent GERD at 1 year postoperatively was 26% versus 7% in group 1 and group 2, respectively, by upper contrast study. Redo surgery was required in 21% versus 3% in group 1 and group 2, respectively.

Conclusions:

Bilateral fixation of the wrap to diaphragmatic crura significantly reduced recurrent GERD, in laparoscopic Nissen fundoplication for neurologically impaired children, with no increased risk of morbidities. Future prospective studies should be conducted with larger patient populations and longer follow-up periods.

Laparoscopic Toupet fundoplication for gastroesophageal reflux: a series of 131 neurologically impaired pediatric cases at a single children's hospital

PURPOSE

To present the medium to long-term outcome of the largest pediatric series of laparoscopic Toupet fundoplications (LTF) performed at a single institution.

PATIENTS AND METHODS

Subjects were 131 neurologically impaired children (81 M, 50 F) who underwent LTF between 2003 and 2013. Our LTF involves full dissection of the crus of the diaphragm to allow the intraabdominal esophagus to be mobilized at least 3-4 cm.

RESULTS

Preoperative mean fraction time for pH <4 was 14.6 %. Mean age at LTF was 6.7 years (3 months-18 years). Mean duration of follow-up was 5.7 years (range 1.2-12.1 years). One case required conversion to open surgery. Intra-operative complications were all injuries to the esophagus/gastric wall (n = 4; 3.0 %) including full-thickness perforation (n = 1; 0.8 %). Postoperative complications included pyloric stenosis (n = 4; 3.0 %), dysphagia (n = 1; 0.8 %), incisional hernia (n = 1; 0.8 %), hemorrhage requiring transfusion (n = 1; 0.8 %), recurrence (n = 3; 2.3 % at 11, 13, and 48 months, respectively), and gastrostomy site infection (n = 7; 5.3 %). Mean operative time decreased significantly with experience from 180.8 min for the first quarter of subjects to 150.6 (2nd quarter), 128.6 (3rd) and 109.2 min (4th).

CONCLUSIONS

Our LTF would appear to be safe for treating GERD in children because of reliable outcome and low recurrence.

Simple fundoplication versus additional vagotomy and pyloroplasty in neurologically impaired children--a single centre experience

BACKGROUND AND AIMS

Gastrooesophageal reflux disease (GERD) is a significant problem in children with neurological impairment (NI) with high failure rates for fundoplication. Fundoplication with vagotomy and pyloroplasty (FVP) can improve the outcome by altering the sensory or motor dysfunction associated with the reflux. We report our comparative outcomes for simple fundoplication (SF) and FVP in NI children.

METHODS

Case records of all patients having fundoplication under a single consultant at a tertiary UK paediatric surgical centre between January 1997 and December 2012 were retrospectively assessed for recurrent symptoms and redo surgery. The data were collected using a Microsoft Excel database and analysed on Graphpad prism software program. Data are median (range). P value<0.05 was considered significant.

RESULTS

Data were available for 244 out of 275 patients who underwent fundoplication during this period (157 SF and 87 FVP). Neurological disease or known syndromes were recorded in 158 patients. Thirty-five children had congenital anatomical abnormalities. Laparoscopic fundoplication was done in 37 cases. Revisional surgery for recurrent symptoms was performed in 22 patients. In the neurologically normal children, all of whom had SF, the revision rate was 6.5%. In the NI children the revision rates were 18.5% for SF and 3.9% for FVP, respectively (Fisher's exact, P<0.05). The median time to redo surgery was 10 (1-63) months, and the median time to follow up was 19.5 (2-177) months.

CONCLUSIONS

There appears to be a significantly lower need for redo surgery following FVP than SF in children with NI.

Management of gastroesophageal reflux disease in pediatric patients: a literature review

Gastroesophageal reflux (GER), defined as the passage of gastric contents into the esophagus, is a physiologic process that occurs throughout the day in healthy infants and children. Gastroesophageal reflux disease (GERD) occurs when gastric contents flow back into the esophagus and produce symptoms. The most common esophageal symptoms are vomiting and regurgitation. Lifestyle changes are the first-line therapy in both GER and GERD; medications are explicitly indicated only for patients with GERD. Surgical therapies are reserved for children with intractable symptoms or who are at risk for life-threatening complications of GERD. The laparoscopic Nissen antireflux procedure is the gold standard for the treatment of this pathology. A literature search on PubMed and Cochrane Database was conducted with regard to the management of GERD in children to provide a view of state-of-the-art treatment of GERD in pediatrics.

Esophago-gastric motility and nutritional management in a child with ATR-X syndrome

X-linked alpha thalassemia mental retardation (ATR-X) syndrome is an X-linked recessive disorder that often involves gastrointestinal symptoms. Aspiration pneumonia related to gastroesophageal reflux has been reported as the major cause of death, but gastrointestinal function has not been well investigated. The present report describes a child with ATR-X syndrome who suffered from periodical episodes of refractory vomiting. We investigated the function of upper alimentary tract and found that esophago-gastric dysmotility and severe gastric volvulus were the major causes of gastrointestinal symptoms. This child was surgically treated with anterior gastropexy and jejunal alimentation through gastrostomy, and the symptoms were relieved with good weight gain. This report may provide insight into the gastrointestinal function and nutritional management in children with ATR-X syndrome.

Comparison of long-term outcomes between open and laparoscopic Thal fundoplication in children

OBJECTIVES

In recent years laparoscopic fundoplication is increasingly performed in pediatric surgery. The aim of this study was to compare the long-term outcomes between open and laparoscopic Thal fundoplication in children.

METHODS

This retrospective study includes children who underwent a Thal fundoplication between 3/1997 and 7/2009. The minimum follow-up time to enter the study was 2 years; the overall median follow-up was 77 months (range, 29-176 months).

RESULTS

A total of 101 patients were included, of which 47 underwent an open and 54 a laparoscopic Thal. Intraoperative problems, early postoperative complications, time to establish enteral feeds and length of stay did not differ among both groups. The mean duration of surgery was significantly less in the open group (OPG) (108.0 (± 7.72) versus 144.1 (± 6.36) minutes; p=0.001) and this was mainly attributed to patients with neurological problems. Severe dysphagia requiring endoscopy was observed in 10 patients, but this did not differ significantly between groups (n=2 in the OPG vs. n=8 in the laparoscopic group (LAPG); p=0.10). Overall 12 patients (11.9%) (6 in each group) required a redo-fundoplication after a median of 18.7 months (range, 6-36 months). In the whole study group, 80 patients (79.2%) were classified as having surgical results being excellent, good or satisfactory and this did not differ significantly between groups.

CONCLUSIONS

In the long-term open and laparoscopic Thal fundoplication have similarly good outcomes. The laparoscopic approach can be considered as an alternative, however there is not a clear superiority compared with the open counterpart.

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.

Antireflux surgery in children with neurological impairment: caregiver perceptions and complications

OBJECTIVES

The aim of the present study was to report caregiver perceptions to antireflux surgery and gastrostomy in children with severe neurological impairment and to report the complications of the surgery.

METHODS

Children were identified from a clinic database and clinical information and surgical complications were extracted from the database and hospital medical records. A cross-sectional questionnaire addressing severity of symptoms was administered to parents/caregivers and scored with a 5-point Likert scale (1 is much better to 5, much worse).

RESULTS

A total of 122 children, median age 74 months (interquartile range 29-124), 63% spastic quadriplegic cerebral palsy, had antireflux surgery. Laparoscopic surgery was performed in 77 of 122 (63%) and 117 of 122 (96%) had gastrostomy insertion. Questionnaire was completed by 89 of 122 (73%) children; median duration of time from fundoplication to questionnaire was 77 months (43-89). The majority of caregivers indicated that surgery improved or greatly improved weight gain, chest infections, vomiting, and feeding tolerance. Only 2 caregivers reported that they regretted consenting to surgery. Serious surgical complications occurred in 10%.

CONCLUSIONS

Serious complications were uncommon in this series of antireflux surgery in neurologically impaired children. Although gagging and retching were common following surgery, a high percentage of caregivers reported improved nutrition, reflux-related symptoms, and high levels of satisfaction.

A modified laparoscopic esophagogastric dissociation for severe bile reflux in a neurologically impaired child

The clinical scenario of a neurologically impaired child with a prolonged history of gastroesophageal reflux disease that underwent open Roux-en-Y gastrojejunostomy with subsequent development of severe symptomatic bile reflux is reported. The presentation, evaluation, and surgical management by laparoscopic revision to a modified esophagogastric dissociation are discussed.

A novel antireflux procedure: gastroplasty with restricted antrum to control emesis (GRACE)

PURPOSE

Nissen fundoplication is the most commonly performed operation to treat gastroesophageal reflux disease and vomiting in children with neurologic impairment. However, failure rates of Nissen fundoplication in this population are higher, and alternatives to Nissen fundoplication have technical and functional disadvantages. We hypothesize that the novel gastroplasty with restricted antrum to control emesis (GRACE) would be more effective than Nissen fundoplication at reducing emetic reflux.

METHODS

To compare the GRACE with Nissen fundoplication, 15 canine subjects were randomized to Nissen fundoplication or GRACE. All subjects underwent gastrostomy tube placement. Baseline gastric emptying, electrogastrography, and induced vomiting studies were performed. Nissen fundoplication or GRACE was then performed. Postoperatively, gastric emptying and vomiting studies were repeated.

RESULTS

Gastric emptying before and after antireflux procedures was not significantly different between groups. Both Nissen fundoplication (38%, P = .04) and GRACE (69%, P < .01) procedures prevented reflux compared with baseline. However, the GRACE procedure significantly reduced reflux when compared with Nissen fundoplication (P = .03).

CONCLUSIONS

In this canine model, GRACE appears to be significantly more effective than Nissen fundoplication at reducing emetic reflux. This novel procedure preserves gastric function and is well tolerated. The GRACE procedure may provide an alternative to Nissen fundoplication as a primary or repeat antireflux procedure for children with neurologic impairment.

Motility problems in the intellectually challenged child, adolescent, and young adult

Gastrointestinal (GI) motility problems represent an important cause of morbidity and sometimes mortality in patients affected by developmental disorders. This article describes motility disorders in Down syndrome, cerebral palsy, familial dysautonomia, and Williams syndrome. These problems do not often receive appropriate attention, either because priority is given to other medical aspects of the disorder, or because of the inability of affected children to communicate their symptoms. A better approach to the diagnosis and treatment of GI disorders is required to improve quality of life and minimize morbidity and mortality among patients with developmental disorders.

Long-term outcome of laparoscopic nissen fundoplication compared with laparoscopic thal fundoplication in children: a prospective, randomized study

BACKGROUND

Laparoscopic fundoplication is increasingly performed in pediatric surgery. Many types of fundoplication are performed, each has advantages and disadvantages. To date there has been no prospective randomized study to determine the optimal laparoscopic technique in children. The aim of the study was to compare the long-term outcomes and control of symptoms after laparoscopic Nissen fundoplication with laparoscopic Thal fundoplication in children.

METHODS

Between July 1998 and April 2007, 175 patients were recruited to this prospective, randomized study. Patients were assessed before the operation and after defined intervals starting at 3 months after surgery. The "absolute" outcome measure for fundoplication failure was recurrence of symptoms that merited a redofundoplication or insertion of a transgastric jejunostomy. "Relative" outcome measures were recurrence of symptoms necessitating reintroduction of antireflux medication (ie, "intention to treat") and postoperative complications (eg, postoperative dysphagia). The median follow-up time was 30 months (range, 1-109). This study has been registered with clinicaltrials.gov (NCT01027975).

RESULTS

Long-term results were available in 167 patients of which 85 underwent a Nissen and 82 a Thal fundoplication. Four patients in the Nissen group (4.7%) and 12 in the Thal group (14.6%) required a redofundoplication. One child in each group developed recurrence of symptoms and had a transgastric jejunostomy performed. The "absolute" failure rate was significant lower in the Nissen group (n = 5; 5.9%) compared with the Thal group (n = 13; 15.9%) (P = 0.038). The vast majority of these patients (17 of 18) had underlying neurological disorders. The "relative" failure rate (ie, "intention to treat") was similar in both groups. Nearly one-quarter of patients developed postoperative dysphagia similarly distributed between both groups. However, severe dysphagia requiring endoscopy +/- dilatation was significantly higher in the Nissen group (n = 10, 11.8%) compared with the Thal group (n = 2; 2.4%) (P = 0.020). One of 31 deaths (0.6%) in this series occurred after surgery, but was not directly related to the fundoplication technique.

CONCLUSIONS

In the long-term a laparoscopic Nissen fundoplication had a significantly lower recurrence rate than a Thal fundoplication, particularly in patients with underlying neurological disorders. There was no significant difference between the 2 types of fundoplication in normal children. There was no significant difference between the need for restarting antireflux medication between both groups because of recurrence of moderate symptoms. The incidence of postoperative dysphagia was similar in the 2 groups, however, significantly more patients in the Nissen group required intervention for severe dysphagia. Overall the perioperative death rate was low even in high-risk patients.

Treating acid reflux disease in patients with Down syndrome: pharmacological and physiological approaches

Down syndrome (DS) is often accompanied by gastrointestinal disease, occurring mainly in early infancy and frequently requiring therapy. Among motility disorders, the most frequent is gastroesophageal reflux disease (GERD), which may often be misdiagnosed because of its atypical manifestations. Early diagnosis of esophageal functional disorders is essential to prevent respiratory problems, growth retardation in children, weight loss in adults, and to establish the correct type of surgery if needed. Furthermore, the involvement of the enteric nervous system in the pathophysiology of GERD in DS is not yet completely understood but seems supported by much evidence. In fact DS is often associated with motor disorders and this evidence must be considered in the choice of therapy: in particular all options available to improve motility seem to be effective in these patients. The effectiveness of therapy is strictly related to the rate of mental impairment, so that modulating therapy is essential, especially in view of the severity of the neurological status.

Laparoscopic fundoplication for gastroesophageal reflux disease in infants and children

The number and types of minimally invasive surgical procedures being performed in children have increased exponentially in the last 15 years. Laparoscopic fundoplication is commonly performed for gastroesophageal reflux disease (GERD), although the population of patients who undergo this procedure is different in adults and children. In Japan, laparoscopic fundoplication has become a standard procedure, even for children with neurological impairment; however, its indications remain controversial. In this article we review the status of laparoscopic antireflux surgery for infants and children, looking at its indications, the procedures available, the complications, and the training required to perform the procedure safely and effectively.

Position paper on laparoscopic antireflux operations in infants and children for gastroesophageal reflux disease. American Pediatric Surgery Association

The use of the laparoscopic approach to perform antireflux procedures has increased dramatically since its introduction in 1991. To date, no prospective randomized studies comparing open surgery to the minimal invasive approach in children have been reported. Many retrospective reviews and case series have demonstrated that laparoscopic antireflux procedures are safe and effective once the learning curve is achieved. This position paper is coauthored by the New Technology Committee of the American Pediatric Surgery Association. The goal is to discuss the ongoing controversies and summarize the available evidence to identify the risks and benefits of laparoscopic antireflux procedures.

Pulmonary care of children and adolescents with developmental disabilities

Caring for children and adolescents with developmental disabilities is challenging because of their susceptibility to varying degrees of respiratory morbidity and mortality. This article discusses the common pulmonary problems affecting children with developmental disabilities. Topics to be discussed include gastroesophageal reflux, drooling, and dysphagia and their relation to aspiration and aspiration pneumonia, upper airway obstruction and obstructive sleep apnea, and the role of airway clearance. Case studies are used to introduce a discussion of the underlying etiology, currently accepted methods to evaluate the conditions, and evidence-based treatment options. The goal of managing these problems is to use anticipatory guidance when possible and choose therapies that improve the child's quality of life with minimal side effects.

Long-term outcome of laparoscopic Nissen-Rossetti fundoplication for neurologically impaired and normal children

BACKGROUND

This study aimed to assess the long-term effects of laparoscopic Nissen-Rossetti fundoplication (LNF) on clinical and pH evaluations of children with gastroesophageal reflux disease (GERD) according to neurologic status.

METHODS

The study examined 127 children (73 neurologically impaired and 54 neurologically normal with primary GERD) who consecutively underwent LNF from 1992 to 2003. The follow-up protocol included evaluations at 3, 15, and more than 36 months (long-term evaluation) postoperatively, which consisted of physical examination and 24-h pH monitoring. Recurrences were defined as abnormal pH-metry exhibited by symptomatic children.

RESULTS

The long-term follow-up period averaged 5.5 years. Of the 73 neurologically impaired children, 9 (12%) had GERD recurrences, which occurred during the evaluation period and required redo surgery in four cases, including two Bianchi procedures. In the neurologically normal group, one recurrence (2%) occurred 3 months after surgery. The long-term complications in this group included dyspepsia (n = 3), occasional dysphagia (n = 2), gas bloat syndrome (n = 1), and alimentary disorders (n = 2).

CONCLUSIONS

For children with primary GERD, LNF is a long-term efficient procedure. For the neurologically impaired children, the results were good, with more than 85% of the children symptom free after 5 years, although repeated evaluations are required to diagnose late recurrences related to evolving dysmotility disorders.

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.

Gastrointestinal tract feeding access and the role of fundoplication in combination with gastrostomy

PURPOSE OF REVIEW

Feeding access and associated antireflux procedures continue to be some of the most common operations performed in pediatric patients. This review will discuss the various feeding access procedures available, including minimally invasive techniques, and further elaborate on appropriate indications for a concurrent antireflux procedure as well as alternatives to fundoplication.

RECENT FINDINGS

Gastrostomy and jejunostomy can be successfully placed using endoscopic or laparoscopic techniques with low complication rates. Nissen fundoplication is well described laparoscopically but failure with recurrent gastroesophageal reflux has resulted in the development of other operative alternatives.

SUMMARY

Decisions concerning appropriate long-term feeding access must be individualized, understanding the advantages and disadvantages of gastrostomy and jejunostomy techniques. Laparoscopic Nissen fundoplication is successful for treatment of patients who fail medical therapy of gastroesophageal reflux, but recurrent gastroesophageal reflux is a persistent problem that requires innovative solutions.

Recurrent gastroesophageal reflux in neurologically impaired patients after fundoplication

AIM

To evaluate the outcome and analyse the main causes of complications and failures of antireflux surgery for gastroesophageal reflux disease (GERD) in neurologically impaired patients (NIP).

METHODS

From 1985 to 1999 44 NIP (mean age 12 years) underwent surgery for GERD. Type of surgery, complications and recurrent reflux were analysed.

RESULTS

Twenty-seven patients (61%) showed preoperatively severe failure to thrive. All patients showed pathologic results in 24-h pH monitoring. Surgical treatment consisted of ventral (n = 25, Thal) or dorsal (n = 4, Toupet) semifundoplication or a Nissen fundoplication (n = 15). Postoperatively, all patients showed an impressive growth, regress of symptoms and improvement of results of diagnostic investigations. Late complications and recurrence of reflux were significantly related to preoperative extreme dystrophy (p < 0.0025). In six patients (15%) severity of symptoms related to recurrent reflux required a reoperation 17.8 month postoperatively (range 8-35 month). Recurrent reflux was found in 40% after ventral semifundoplication and in 46% after Nissen fundoplication (8 and 47 months postoperatively, respectively).

CONCLUSION

Symptoms improved impressively after fundoplication in mentally retarded children. The incidence of recurrent reflux is not related to the type of surgery, however, it occurs significantly earlier with ventral semifundoplication when compared with Nissen fundoplication. Both late complications as well as recurrent reflux are related significantly to preoperative dystrophy.

National trends in the use of antireflux procedures for children

OBJECTIVE

The purpose of this study was to analyze recent nationwide trends in the use of and outcomes after antireflux surgery for children.

METHODS

We conducted a retrospective cohort study of children (age: <18 years) undergoing antireflux surgery by using data from 1996 to 2003 from the Nationwide Inpatient Sample. Census data were used to calculate the population-based rates of procedures stratified according to age and presence of neurologic impairment. Multivariate analyses were performed to determine factors associated with length of stay and in-hospital death.

RESULTS

During the study period, 48,665 antireflux procedures were performed for children in the US. Although procedure rates were generally higher in 2003 than in 1996, no trends in rates were observed among different age groups and census regions during the study period. The highest population-based procedure rates were observed among infants (49-101 procedures per 100,000 population). There was a significant decrease in the percentages of children undergoing antireflux procedures who were neurologically impaired between 1996 and 2003 (53% vs 40%). Neurologically impaired children had longer lengths of stay and higher mortality rates than did neurologically normal children.

CONCLUSIONS

Although procedure rates have not changed, the use of antireflux surgery has evolved during the laparoscopic era, with a decreasing percentage of neurologically impaired children undergoing this procedure. Antireflux procedures were performed predominantly for infants, most of whom were neurologically normal. Neurologically impaired children remain a group at high risk for death after antireflux procedures.

Laparoscopic modified Thal fundoplication for gastroesophageal reflux in a patient with severe scoliosis and sliding esophageal hiatal hernia

A 14-year-old girl with severe scoliosis and sliding esophageal hiatal hernia underwent laparoscopic fundoplication for gastroesophageal reflux. Of various fundoplication procedures, anterior partial fundoplication (Thal fundoplication) was performed because it is effective, with less postoperative gas bloat syndrome. Laparoscopic fundoplication in severely scoliotic children could allow improved operative visibility and easier access to the hiatus in comparison with the open approach. In our "modified anterior partial fundoplication," the sutures between the crura and the esophagus and the sutures on the left of esophageal wall with the fundus of the stomach could be exactly performed by laparoscopic surgical technique. The wrapping of the esophagus in fundoplication was done over the ventral 180 degrees to 270 degrees. Six months postoperatively, the patient did not develop gas bloat syndrome, distal esophageal obstruction from fundoplication, and delayed gastric emptying. Modified anterior partial fundoplication achieves effective control of reflux symptoms.

Endoscopic gastrostomy placement in the child with gastroesophageal reflux: is concomitant antireflux surgery indicated?

BACKGROUND/PURPOSE

Previously, we performed concomitant antireflux surgery in patients with abnormal pH study undergoing gastrostomy. This increased complications without always alleviating the troublesome symptom of vomiting. In contrast, vomiting with normal preoperative pH study generally disappeared after gastrostomy placement. Therefore, we changed policy to perform only gastrostomy, regardless of pH study results. Subsequent antireflux surgery is performed only as necessary. We report here our results.

METHODS

We retrospectively reviewed patients undergoing gastrostomy from April 1997 to January 2004. For patients with abnormal preoperative pH studies, detailed data were recorded including medical history, indication for gastrostomy, operative technique, symptoms of gastroesophageal reflux (GER), and use of antireflux medication. Symptomatic GER postgastrostomy was managed pharmacotherapeutically. If this proved inadequate, patients underwent antireflux surgery.

RESULTS

Twenty-eight patients with abnormal pregastrostomy pH study entered the study. Median age was 3 years and 2 months. Seventy-five percent were neurologically impaired. Indication for gastrostomy was inadequate oral nutrition in 26 of 28 patients. Only 3 of 28 patients were asymptomatic for GER. Of the 25 symptomatic patients 19 improved postgastrostomy (6 did not). Antireflux surgery ultimately proved indicated in 2 patients (7% [2/28]). The asymptomatic patients remained asymptomatic.

CONCLUSIONS

For patients with abnormal pH study presenting primarily for gastrostomy placement, concomitant antireflux surgery is not indicated.

Long-term results of boerema anterior gastropexy in children

OBJECTIVES

To analyze the long-term results of Boerema anterior gastropexy using the Visick grading system in a university teaching hospital.

METHODS

Retrospective review of 247 children with severe or complicated gastroesophageal reflux disease (GERD). Patients who underwent primary gastropexy between 1990 and 2001 were divided in 3 groups: (A) neurologic impaired patients (n = 83); (B) esophageal atresia patients (n = 36); and (C) patients without underlying disease (n = 128). The median length of follow-up after gastropexy was 7 years and 8 months (range, 1.5-13 years). Follow-up was carried out using a standardized questionnaire and was obtained by telephone. Postoperative recurrence of symptoms during follow-up was considered as failure of the operation.

RESULTS

Postoperative complications occurred in 20 patients (24%) in group A, in 13 patients (36%) in group B and in 23 patients (18%) in group C. Thirty-three patients died during the follow-up period, 5 of whom during the postoperative period. Six children could not be traced; thus, 208 were available for long-term follow-up. Postoperative failures occurred in 12 patients (23%) in group A, in 11 patients (31%) in group B and in 17 patients in group C (14%). Reoperation for recurrence of symptoms due to GERD was performed in 6 patients in group A, in 7 patients in group B and in 2 patients in group C. The final outcome at the time of interview was successful in 81% of group A, in 88% of group B and in 91% of group C.

CONCLUSIONS

In the long term, Boerema anterior gastropexy is an effective operation for complicated GERD in children without underlying disease as well as in neurologically impaired children and patients with esophageal atresia.

Nutrition support for neurologically impaired children: a clinical report of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition

Undernutrition, growth failure, overweight, micronutrient deficiencies, and osteopenia are nutritional comorbidities that affect the neurologically impaired child. Monitoring neurologically impaired children for nutritional comorbidities is an integral part of their care. Early involvement by a multidisciplinary team of physicians, nurses, dieticians, occupational and speech therapists, psychologists, and social workers is essential to prevent the adverse outcomes associated with feeding difficulties and poor nutritional status. Careful evaluation and monitoring of severely disabled children for nutritional problems are warranted because of the increased risk of nutrition-related morbidity and mortality.

Does epilepsy influence the outcome of antireflux procedures in neurologically impaired children?

In neurologically impaired patients (NIP), surgical management of gastroesophageal reflux disease (GERD) has become a widespread standard. Several follow-up studies have shown a high incidence of complications and recurrent reflux. As one of the possible causes epilepsy is mentioned repeatedly in the literature. The aim of this study was to determine the effective impact of epilepsy on the postoperative outcome by comparing results of our patients suffering from epilepsy to those without this disorder. From 1984 to 1999, a total of 45 NIP underwent antireflux surgery, including 20 patients suffering from epilepsy (EP) and 25 patients without this disorder (nEP). The existence of epileptic disorders, incidence of epileptic seizures and administration of anticonvulsatory drugs as well as results of diagnostic procedures, postoperative complications and incidence and time of recurrence of pathologic GER were recorded and analysed retrospectively. Preoperatively all patients had pathologic results in 24 h pH-monitoring. Median RI was 15.75 (EP, range 5.2-28.6) and 17.55 (nEP; range 7.2-26.5). 12-months-postoperative 24 h pH-monitoring showed a median RI of 3.8 (EP; range 1.3-25.6) versus a median RI of 3.3 (nEP; range 0.7-26.3). During the long-term follow-up evaluation of 3.9 years, 17 EP suffered from persistent epileptic seizures despite medical treatment. 19 patients (42%) developed recurrent reflux. This included seven EP (35%) and 12 nEP (48%). The necessity of reoperation was higher in nEP (n = 5, 20%) than in EP (n = 1, 5%). This analysis did not show a significant correlation between recurrence of pathologic GER after fundoplication and the incidence of epileptic seizures. We consider our findings to strongly question the widespread opinion considering this correlation. We conclude, that cerebral seizures alone do not alter the operative outcome of antireflux surgery in NIP.

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.

Gastrointestinal complications of fundoplication

In children with medically refractory gastroesophageal reflux disease (GERD), fundoplication is effective and safe. However, in a subset of patients, gastrointestinal dysfunction occurs postoperatively. Symptoms include chest pain, persistent dysphagia in 5%, gas bloat in 2% to 4%, diarrhea in up to 20%, and dumping syndrome in up to 30%. Symptoms are often nonspecific, arising from recurrent or persistent GERD, anatomic complications such as disrupted or herniated wrap, functional disturbances such as rapid gastric emptying or altered gastric accommodation, or alternative diagnoses such as cyclic vomiting syndrome or food allergy. Detailed investigation, including various combinations of pHmetry, videofluoroscopy, endoscopy, motility studies, and dumping provocation testing, may be required to clarify pathophysiology and guide management.

Laparoscopic-assisted jejunostomy

BACKGROUND

Feeding difficulties and gastroesophageal reflux (GER) are major problems in severely neurologically impaired children. Many patients are managed with a simple gastrostomy, with or without fundoplication. Unfortunately, fundoplication and gastrostomy are not devoid of complications, indicating the need for other options in the management of these patients.

METHODS

Since January 2002, seven patients (age range, 5-14 years) have been treated by creating a jejunostomy with the laparoscopic-assisted procedure. The procedure was performed using two 10-mm trocars. The technique consists of identifying the first jejunal loop, grasping it 20-30 cm away from the Treitz ligament with fenestrated atraumatic forceps, and exteriorizing it to the trocar orifice under visual guide. The jejunostomy was created outside the abdominal cavity during open surgery. At the end of the jejunostomy, the correct positions of the intestinal loop and feeding tube were evaluated via laparoscopy.

RESULTS

Surgery lasted 40 min on average, the laparoscopic portion only 5 min. There were no perioperative complications; hospital stay was 3 or 4 days for all patients. At the longest follow-up (18 months), all patients had experienced a significant weight gain, with a high level of parental satisfaction. One patient died 1 year after the procedure of unknown causes. All the others are well, without complications or problems, and their parents are extremely satisfied with the improved quality of life of their children.

CONCLUSIONS

Laparoscopic-assisted jejunostomy is a safe and effective procedure to adopt in neurologically impaired children with feeding problems and GER. This procedure solves these patients' feeding problems even if the reflux is not completely eliminated. We advocate the use of this procedure in neurologically impaired patients with feeding problems and reflux due to its overall practicability and because there is minimal surgical trauma. This technique is extremely safe because the surgeon is able to verify, at the end of procedure, the status of the jejunostomy from outside and inside the abdominal cavity. The improvement in the quality of life of these children after the jejunostomy seems to be the major advantage of this procedure.

Can laparoscopic antireflux surgery improve the quality of life in children with neurologic and neuromuscular handicaps?

PURPOSE

Children with neurologic and neuromuscular handicaps frequently have various symptoms related to gastroesophageal reflux (GER) disease. The long-term efficacy of antireflux surgery remains controversial in such children with GER. The clinical results of such patients who underwent laparoscopic fundoplication were examined in the current study.

METHODS

Between 1997 and 2003, laparoscopic fundoplication was performed in 56 handicapped children (mean age, 6 years), and gastrostomy was performed concurrently in 52. The main symptoms were emesis/hematemesis in 40 and respiratory symptoms, including repeated respiratory infection and distress, in 31.

RESULTS

There were no severe postoperative complications or operative mortality. Emesis/hematemesis was controlled adequately in those without recurrence. Respiratory symptoms were controlled unsuccessfully in 16 patients (52%), 8 of whom required further respiratory care including nasal airway tube, tracheostomy, and laryngotracheal separation. Recurrence of GER disease occurred in 10 patients, 7 of whom underwent a second Nissen fundoplication successfully. Thirteen died within the median follow-up period of 14 months.

CONCLUSIONS

Laparoscopic fundoplication is effective in controlling emesis/hematemesis, but its efficacy is limited in terms of respiratory problems in handicapped children. Further refinements in diagnostic and treatment strategies are mandatory to improve the quality of life in such patients.

Complications of laparoscopic surgery in neonates and small infants

PURPOSE

The difficulty of performing laparoscopic surgery in small infants remains a common complaint of pediatric surgeons. The aim of this study was to evaluate the complications of laparoscopic surgery in small infants weighing less than 5 kg.

METHODS

Since 1997, 154 infants weighing less than 5 kg underwent laparoscopic surgery (group S). During that same period, 96 infants weighing less than 10 kg (group M) and 335 children weighing more than 10 kg (group L) also underwent laparoscopic surgery. Intra- and postoperative complications were evaluated and compared between the 3 groups, especially in the 60 cases that underwent Nissen fundoplication. P < .05 was considered a significant difference.

RESULTS

Complications such as gastrointestinal perforation and wound infection were observed in 15 (9.7%), 15 (15.6%), and 32 (9.6%) infants of groups S, M, and L, respectively. There were no significant differences in complication rates among the 3 groups. However, in Nissen fundoplication, 5 of 15 patients in group S had complications, thereby significantly increasing the complication rate as compared with group L (1 of 23, P = .04). Major complications in group S were gastrointestinal perforation and vagal nerve injury.

CONCLUSIONS

Laparoscopic surgery is feasible even in small infants. However, in Nissen fundoplication, special attention is necessary to avoid severe intraoperative complications.
