The failed fundoplication

10 Year Follow-Up of Randomized Trial of Laparoscopic Nissen Versus Thal Fundoplication in Children

Introduction: The aim of this study was to compare the long-term outcomes of laparoscopic complete (Nissen) fundoplication (LNF) with laparoscopic partial (Thal) fundoplication (LTF) in children. This is the only prospective, randomized study to follow patients up for more than 10 years. Interim results published in 2011 at median 2.5 year follow-up showed that LNF had a significantly lower failure rate compared with LTF. Materials and Methods: A randomized, controlled trial of LNF versus LTF in children (<16 years) was performed. The primary outcome measure was "absolute" failure of the fundoplication-recurrence of symptoms that merited either reoperation or insertion of transgastric jejunostomy (GJ). Secondary outcomes were "relative" failure (need for postop antireflux medication), complications (e.g., dysphagia), and death. Results: One hundred seventy-five patients were recruited; 89 underwent LNF, and 86 underwent LTF. Eight patients had no follow-up recorded. At long-term follow-up, 59 patients had died (35%); LNF 37/85 (43.5%) and LTF 22/82 (26.8%), P = .02. Median length of follow-up in survivors was 132 months. There was no statistically significant difference in "absolute" failure rate between LNF 8/85(9.4%) and LTF 15/82 (18%), P = .14. There was no difference in "relative" failure between LNF 7/85 (8.2%) and LTF 12/82 (14%), P = .23. Long-term dysphagia affected 5 out of 108 (4.6%) patients; 3/48 (6.2%) of LNF and 2/60 (3.3%) of LTF (P = .65). Conclusions: There was no statistically significant difference in 'absolute' failure between LNF and LTF at long-term follow-up. Neurologically impaired children have a high mortality rate following fundoplication due to comorbidities. This trial commenced in 1998 and was approved by the Oxfordshire Research Ethics Committee (No. 04.OXA.18-1998).

Postpyloric Feeding Access in Infants and Children: A State of the Art Review

Achieving postpyloric feeding access is a clinical challenge faced by the pediatric gastroenterologist in everyday practice. Currently, there is limited literature published on the topic. This article provides a practical summary of the literature on the different methods utilized to achieve postpyloric feeding access including bedside, fluoroscopic, endoscopic and surgical options. Indications and complications of these methods are discussed as well as a general approach to infants and children that require intestinal feeding.

The "omega" jejunostomy tube: A preferred alternative for postpyloric feeding access

AIM

We present our technique for construction of the "Omega Jejunostomy" (OJ), a novel method of postpyloric feeding using a pouched-jejunal loop capable of accommodating a balloon gastrostomy button. We describe potential indications for the procedure and outcomes in a complex patient population.

MATERIALS AND METHODS

We retrospectively reviewed records of patients who underwent an OJ at our institution between 2005 and 2014. Primary outcomes include operating time, length of hospital stay, time to feeding goals, and postoperative complications.

RESULTS

We identified 12 children (6 males) with multiple comorbidities who underwent OJ procedures. The median age at surgery was 11years (range 3months-23years). Eleven patients had failed previous alternative feeding access or antireflux procedures. All patients eventually reached their feeding goals. Eight were at goal feeds in <10days. Two achieved goal feeds <1month, one <4months, and one within 7months. There was one OJ failure because of fistula formation requiring surgical revision, and one child was treated successfully but died of unrelated causes. Four children eventually transitioned to PO or G-tube feeds, and six were tolerating feeds via OJ at last follow-up (8-74months).

CONCLUSIONS

OJ provides a durable alternative to gastrojejunostomy tube for patients who are poor candidates for or have failed Nissen fundoplication. It is technically easier to perform than a gastroesophageal disconnect procedure, has minimal surgical comorbidities, and can provide durable feeding access and achievement of goal feeds in a complex and refractory patient subset.

Fundoplication and gastrostomy versus percutaneous gastrojejunostomy for gastroesophageal reflux in children with neurologic impairment: A systematic review and meta-analysis

BACKGROUND

Children with neurologic impairment often fail medical management of gastroesophageal reflux and proceed to fundoplication and gastrostomy (FG) or percutaneous gastrojejunostomy (GJ). Current guidelines do not recommend one treatment over the other, and there is ongoing uncertainty regarding clinical management.

METHODS

We conducted a structured search of Medline, Embase, trial registries, and the gray literature. We included studies that compared outcomes for FG and GJ in children with neurologic impairment.

RESULTS

We identified 556 children from three retrospective studies who underwent FG (n=431) or GJ (n=125). There were no differences in rates of pneumonia (17% vs 19%, p=0.74) or mortality (13% vs 14%, p=0.76). Few deaths were due to procedural complications (1%) or reflux (2%). There was a trend towards more major complications with FG (29%) compared to GJ (12%) (risk ratio=1.70, 0.85-3.41, p=0.14). Minor complications were more common with GJ (70%) than FG (45%), but this difference was also not statistically significant (risk ratio=0.38, 0.05-3.07, p=0.36). No studies reported quality of life using validated measures.

CONCLUSIONS

The quality of the evidence for outcomes of FG versus GJ is very low. Large comparative studies are needed to determine which approach is associated with the best quality-of-life outcomes.

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.

A novel continuous stitch fundoplication utilizing knotless barbed suture in children with gastroesophageal reflux disease: a pilot study

INTRODUCTION

The intracorporeal placement and tying of suture (IT) can be challenging leading to prolonged CO2 insufflation, anesthesia, and potential morbidity. The unidirectional barbed knotless suture (V-LOC) has emerged as an innovative technology that has been shown to reduce the time associated with IT. Therefore, we conducted a retrospective analysis comparing our initial experience utilizing V-LOC to perform a novel continuous stitch laparoscopic fundoplication (CF) to standard laparoscopic Nissen fundoplication (NF).

METHODS

Institutional review board approval was obtained to analyze data on patients who underwent V-LOC CF and NF. Data retrieval included age, gender, weight, diagnosis, procedure, operative time, major complications (reoperation for wrap failure/migration or recurrent symptoms), and follow up.

RESULTS

Twenty patients underwent the V-LOC CF and gastrostomy placement (GT) from January to October 2013. Seventeen patients underwent NF and GT from March 2012 to February 2013. There were no significant differences in age, weight, or incidence of major complications. V-LOC CF led to a significant 30% reduction in operative time compared to NF (79.1±24.2 min vs. 113.8±25.9 min, respectively, P<0.05).

CONCLUSIONS

This is the first report documenting the continuous stitch fundoplication utilizing the unidirectional barbed knotless suture in children. Although follow-up is short, the V-LOC CF appears to be a safe and effective technique that may reduce operative time in children with gastroesophageal reflux disease. This technology may be beneficial in other minimally invasive applications in pediatric surgery.

Total esophagogastric dissociation in adult neurologically impaired patients with severe gastroesophageal reflux: an alternative approach

Patients with neuromuscular impairment, such as cerebral palsy or myotonic dystrophy, often suffer from oropharyngeal neuromuscular incoordination and severe gastresophageal reflux (GER). In 1997, Bianchi proposed total esophagogastric dissociation (TEGD) as an alternative to fundoplication and gastrostomy to eliminate totally the risk of recurrence of GER in neurologically impaired children. Little information exists about the best management for adult patients with severe neurological impairment in whom recurrent GER develops after failed fundoplication. We present our experience in three adult patients with neurological impairment in whom TEGD with Roux-en-Y esophagojejunostomy and feeding gastrostomy was performed for permanent treatment of GER.

Reiterative laparoscopic surgery for recurrent gastroesophageal reflux

Laparoscopic Nissen fundoplication is successful in preventing reflux in more than 95% of patients. However, over time, there appears to be failure of the fundoplication either with wrap breakdown and/or transmigration of the wrap through the esophageal hiatus in 5% to 10% of patients. It is unlikely that medical management will be successful in controlling the reflux symptoms following either wrap breakdown and/or transmigration. Thus, operative repair for control of recurrent symptoms is required in most cases. This article outlines the etiology for recurrent gastroesophageal reflux disease, presentation of the patient with wrap failure or transmigration, steps which the authors have taken to help prevent these complications from developing, and our approach for those patients who require re-operation.

Vertical gastric plication versus Nissen fundoplication in the treatment of gastroesophageal reflux in children with cerebral palsy

CONTEXT AND OBJECTIVE

Association between neurological lesions and gastroesophageal reflux disease (GERD) in children is very common. When surgical treatment is indicated, the consensus favors the fundoplication technique recommended by Nissen, despite its high morbidity and relapse rates. Vertical gastric plication is a procedure that may have advantages over Nissen fundoplication, since it is less aggressive and more adequately meets anatomical principles. The authors proposed to compare the results from the Nissen and vertical gastric plication techniques.

DESIGN AND SETTING

Randomized prospective study within the Postgraduate Surgery and Experimentation Program of UNIFESP-EPM, at Hospital do Servidor Público Estadual (IAMSPE) and Hospital Municipal Infantil Menino Jesus.

METHODS

Fourteen consecutive children with cerebral palsy attended between November 2003 and July 2004 were randomized into two groups for surgical treatment of GERD: NF, Nissen fundoplication (n = 7); and VGP, vertical gastric plication (n = 7). These were clinically assessed by scoring for signs and symptoms, evaluation of esophageal pH measurements, duration of the operation, intra and postoperative complications, mortality and length of hospital stay.

RESULTS

The mean follow-up was 5.2 months; symptoms were reduced by 42.8% (NF) (p = 0.001) and 57.1% (VGP) (p = 0.006). The Boix-Ochoa score was favorable for both groups: NF (p < 0.001) and VGP (p < 0.042). The overall mortality was 14.28% in both groups and was due to causes unrelated to the surgical treatment.

CONCLUSION

The two operative procedures were shown to be efficient and efficacious for the treatment of GERD in neuropathic patients, over the study period.

The current role of laparoscopic surgery for gastroesophageal reflux disease in infants and children

BACKGROUND

The benefits of surgery for gastroesophageal reflux disease (GERD) in infants and children have been questioned in the recent literature. The goal of this review was to determine the best current practice for the diagnosis and management of this disease.

METHODS

The literature was reviewed for all recent English language publications on the management of GERD in 8- to 10-year-old patients.

RESULTS

In infants and children, GERD has multiple etiologies, and an understanding of these is important for determining which patients are the best surgical candidates. Proton pump inhibitors (PPIs) have become the mainstay of current treatment for primary GERD. Although laparoscopic surgery appears to be better than open surgery, there remains some morbidity and complications that careful patient selection can minimize.

CONCLUSION

Surgery for GERD should be performed only after failure of medical management or for specific problems that mandate it.

Revision Nissen fundoplication can be completed laparoscopically with a low rate of complications: a single-institution experience with 72 children

PURPOSE

Recurrent gastroesophageal reflux is a common complication after fundoplication and is often treated with revision fundoplication. We report our experience with laparoscopic redo fundoplication.

METHODS

The medical records of all patients in whom laparoscopic revision fundoplication was attempted over a 7 1/2-year period were reviewed.

RESULTS

Redo laparoscopic fundoplication was attempted in 72 pediatric patients. Ten patients had undergone initial open fundoplication, and 9 additional patients had prior abdominal surgery. Fifty-one percent of patients were neurologically impaired. Laparoscopic fundoplication was completed in 89% of first-time redo operations and 68% of second revisions with average operative times of 2.2 +/- 1.0 and 2.6 +/- 0.9 hours, respectively. Herniation of the fundoplication through the hiatus was common (75%) and the fundoplication was intact in 49%. Conversions to laparotomy were because of difficulties with dissection or visualization. No patients required intraoperative transfusion. No patients required reoperation in the perioperative period. There were no perioperative deaths. Twenty-six percent of the 72 patients went on to a third operation for gastroesophageal reflux, and 4 of these had a fourth.

CONCLUSION

Revision laparoscopic fundoplication is a technically challenging operation but can usually be completed and is characterized by a low rate of complications.

Gastroesophageal reflux in infancy and childhood

GER is a common reason for pediatric office visits and referrals to a pediatric gastroenterologist. This condition frequently is benign, and it is self-limited in most infants. Although a thorough history and complete physical examination usually are adequate to diagnose GER, a high index of suspicion must be maintained for other diagnoses associated with recurrent emesis, including metabolic disorders, as well as for other gastrointestinal conditions, such as pyloric stenosis and abnormalities of intestinal rotation. Behavioral or lifestyle modification usually can be implemented empirically to diagnose and manage a suspected case of uncomplicated GER. When this fails, medical therapy can be initiated, employing either a step-up or step-down approach with a PPI or H2RA. With the proven efficacy of PPIs and their availability to children, medical treatment has become the mainstay of therapy in severely affected patients; nevertheless, anti-reflux surgery is still widely performed in children with GER. Pediatricians and other primary care providers often manage infants and children who have gastrointestinal complaints, prior to referral to a pediatric gastroenterologist. Hence, they have the responsibility to educate children and families about GER, its natural history, complications, and therapeutic options. A careful history and physical examination, informed use of diagnostic studies, and a consistent approach to medical treatment are important principles that are required to guarantee the success of GER management in infants and children.

Total oesophagogastric dissociation: experience in 2 centres

BACKGROUND/PURPOSE

Neurologically impaired (NI) children have an increased incidence of gastroesophageal reflux and many will require surgery.

METHODS

The case notes of 50 NI children who underwent total oesophagogastric dissociation (TOGD) were reviewed. Thirty-four were done as a primary procedure, and 16 were rescues for failed fundoplications.

RESULTS

There was no operative mortality. Morbidity consisted of 1 subphrenic collection, 1 oesophagojejunal dehiscence and 2 stenoses that responded to dilatation, and 2 bowel obstructions. In 1 case, partial gastric resection was needed because of transhiatal herniation of stomach. Gastrostomy feeding was established by 3 to 5 days. The mean hospital stay was 10.9 days. At 4 months to 11 years of follow-up, there was no recurrence of reflux. Children who could swallow enjoyed oral feeds. Their general health and weight SD scores improved. Food aspiration, chest infections, and hospitalizations were reduced, with an improvement in quality of life. There were 5 late deaths in the "primary" and 7 in the "rescue" group from deterioration in their original condition.

CONCLUSION

Total oesophagogastric dissociation is a safe and versatile procedure without immediate mortality and limited surgery-related morbidity. Review of our practice suggests TOGD should be considered as a primary procedure in severely NI children with gastroesophageal reflux and significant oropharyngeal incoordination and dependence on enteral tube feeding. Rescue TOGD carries a greater morbidity because of previous surgery with consequent difficult dissection, poor oesophageal tissue, and higher incidence of vagal nerve injury.

Antireflux surgery outcomes in pediatric gastroesophageal reflux disease

OBJECTIVES

Antireflux surgery is performed frequently in children with gastroesophageal reflux disease (GERD). Few comparative studies exist which assess the indications for and short- or long-term outcome of open Nissen fundoplication (ONF) and laparoscopic Nissen fundoplication (LNF) for pediatric GERD. We investigated the frequency of reoperation and factors that might influence its occurrence.

METHODS

We performed a retrospective, follow up cohort study of all children </=5 years, who underwent LNF or ONF at our institution from January 1, 1997 to December 31, 2002, where five pediatric surgeons perform fundoplication. Mean follow up time was 36.2 months. The following information was obtained: surgical indications, hospital course data, and long-term surgical outcomes. Data were analyzed using univariate and multiple logistic regressions.

RESULTS

Overall, 456 (150 [32.9%] ONF vs. 306 [67.1%] LNF) cases were analyzed. Reoperation was performed in 55 (12.06%), LNF 43 (14.05%), and ONF 12 (8%). The mean interim to reoperation for LNF was 11 months compared to 17 months for ONF (p= 0.007). The reoperation rate at 12 and 24 months were 10.5%, 13.4% and 4%, 6.7% respectively, when LNF was compared to ONF (p= 0.01). The multivariate analysis showed that initial LNF and prematurity were the main predictors for reoperation.

CONCLUSIONS

The majority of reoperations for both LNF and ONF occurred in the first year after initial operation; LNF had a significantly higher reoperation rate than ONF. The probability of reoperation for LNF and ONF increases with the presence of comorbidities, especially prematurity and chronic respiratory conditions.

Gastroesophageal reflux disease: could intervention in childhood reduce the risk of later complications?

Gastroesophageal reflux (GER) is a ubiquitous disorder in infants. Whereas infants typically outgrow regurgitation by 1 year of age, the prevalence of gastroesophageal reflux disease (GERD) symptoms in those aged 3 to >18 years ranges from 1.8% to 22%. The pathophysiology of GERD in children is similar to that in adults. However, children may present with gastroesophageal and extraesophageal symptoms distinct from classic heartburn. In addition to a growing awareness of the high prevalence of the disorder, increasing evidence supports GERD being a lifelong condition in some individuals that begins in childhood. Although the diagnostic workup in children compared with adults may differ, studies suggest that the early detection and treatment of GERD in childhood may result in better adult disease outcomes, improved quality of life, and decreased overall healthcare burden. Studies of proton pump inhibitor therapy in children confirm high rates of mucosal healing and GER symptom resolution, even in children whose symptoms did not respond to H2-receptor therapy or fundoplication procedures. Omeprazole, lansoprazole, and esomeprazole are formulated as capsules containing enteric-coated granules that can be sprinkled onto applesauce or other soft foods. Lansoprazole is also formulated as strawberry-flavored granules for suspension. These as well as other alternative dosing formulations expand the ability to administer these agents to children. Moreover, long-term studies in adults and in children demonstrate that these agents are safe and well tolerated, even at the higher milligram per kilogram doses that are often required in pediatric patients because of their greater hepatic metabolic capacity.
