Technique and complications of percutaneous endoscopic gastrostomy in children

Technology-dependent children

In recent past, revolution in medical technology resulted in improved survival rates and outcomes of critically ill children. Unfortunately, its impact relating to morbidity is not well documented. Although survival rates of these critically ill children who are medically fragile and technology-dependent have improved, we as health professionals are still in the learning curve to improve the quality of life of these children at home. Factors such as support from society, infrastructure, and funding play an important role in technology-dependent child care at home. In this review, commonly prescribed home-based medical technologies such as home ventilation, enteral nutrition, renal replacement therapy, and peripherally inserted central catheter, which are useful for quick revision, are described.

Infant Percutaneous Endoscopic Gastrostomy: Risks or Benefits?

BACKGROUND/AIMS

To present a single center's experience with percutaneous endoscopic gastrostomy (PEG) tube placement in infants.

METHODS

Clinical records of infants who underwent PEG tube placement between January 2010 and December 2015 were reviewed. All patients underwent an upper gastrointestinal contrast study and an abdominal ultrasonography before the procedure. PEGs were performed with a 6-mm endoscope using the standard pull-through technique. Data regarding gestational age, birth weight, age and weight, days to feeding start, days to full diet, and complications were reviewed.

RESULTS

Twenty-three patients were included. The most common indication was dysphagia related to hypoxic-ischemic encephalopathy. Median gestational age was 37 weeks (range, 24-41) and median birth weight was 2,605 grams (560-4,460). Patients underwent PEG procedures at a median age of 114 days (48-350); mean weight was 5.1 kg (3.2-8.8). In all patients but one, a 12-Fr tube was positioned. Median feeding start was 3 days (1-5) and on average full diet was achieved 5 days after the procedure (2-11). Six minor complications were recorded and effectively treated in the outpatient clinic; no major complications were recorded.

CONCLUSIONS

PEG is safe and feasible in infants when performed by highly experienced physicians.

Antibiotic prophylaxis in the management of percutaneous endoscopic gastrostomy in infants and children

BACKGROUND

In randomized controlled trials in adult patients the use of prophylactic broad-spectrum antibiotic reduces the number of insertion site and systemic infections, associated with placement of percutaneous endoscopic gastrostomy (PEG) tubes. For pediatric patients no such trials exist. The aim of this study was to assess the value of antibiotic prophylaxis in PEG placement in pediatric patients.

METHODS

In a retrospective chart review PEG placement in infants and children performed in a tertiary care center was analyzed. All PEG procedures were performed by an experienced pediatric gastroenterologist using the pull-through technique under general anesthesia.

RESULTS

A total of 103 procedures were analyzed; 33 patients received antibiotic prophylaxis and 70 did not. Two (6%) of the patients receiving prophylaxis developed local or systemic infections after PEG placement, whereas seven (10%) without prophylaxis suffered from a PEG-related infection. This difference was not significant on chi-squared test (P = 0.5). Sixty patients had a body temperature >38°C within the first 3 days after the PEG procedure. A total of 77% of these patients had no antibiotic prophylaxis. Mean body temperature differed significantly between patients with and without prophylaxis (37.9°C vs. 38.3°C, respectively; P = 0.02).

CONCLUSIONS

The incidence of PEG-related local or systemic infection after PEG-placement was not significantly different between patients with and without antibiotic prophylaxis, but the latter had a significantly higher mean body temperature after the PEG procedure. Taking elevated mean body temperature as a marker for putative bacteremia it is suggested that antibiotic prophylaxis is indicated in all pediatric patients after PEG placement.

Gastrostomy matters--the impact of pediatric surgery on caregiver quality of life

INTRODUCTION

While pediatric surgeons consider gastrostomy to be routine treatment for children with feeding difficulties, the impact on the family is not fully understood. This study focuses on Quality of Life (QoL) of parents of children who require a gastrostomy tube.

METHODS

A prospective repeated measures cohort study was conducted between November 2009 and March 2012. Demographic, surgical, and QoL data were collected at Baseline, 2 weeks, 3, 6, 9, and 12 months after surgery. At each time-point parents completed three QoL measures: Short Form 36v2 (SF-36), Caregiver Strain Index (CSI), and Parent Experience of Childhood Illness (PECI).

RESULTS

A total of 31 caregivers were recruited with a mean age of 32.6 years (SD=7.0). Overall, a 38% increased risk of depression was seen in the SF-36 when compared to population norms, and a moderate effect was seen in mental health at 12 months (ES=0.56). The CSI demonstrated a decrease in caregiver burden (8.72 to 7.05, p=0.007, 95% CI (0.57-3.18)), while the PECI revealed a decrease in frequency of feelings of guilt, worry, sorrow, anger, and long term uncertainty over 12 months.

CONCLUSION

Gastrostomy not only improves the child's physical health, but also improves the mental health of the child's caregivers, especially at (or after) one year.

The relationship between percutaneous endoscopic gastrostomy and gastro-oesophageal reflux disease in children: a systematic review

BACKGROUND

The relationship between percutaneous endoscopic gastrostomy (PEG) insertion and gastro-oesophageal reflux disease (GERD) is widely disputed in the current literature. The aim of this systematic review is to examine the available evidence documenting the association between PEG and GERD.

METHODS

The following databases were searched: MEDLINE (1950 to week 2, January 2011), PubMed, ISI Web of Knowledge (1898 to week 2, January, 2011), EMBASE (1980 to week 2, January 2011) and The Cochrane Central Register of Controlled Trials (CENTRAL) using the terms "gastroesophageal reflux", "gastroesophageal disease", "GERD", "GERD", "GER", "GER" and "percutaneous endoscopic gastrostomy", "PEG", "gastrostomy". In addition, the reference lists of all included studies were reviewed for relevant citations. Studies examining children pre and post insertion of PEG for GERD and written in English language were included. Data extraction was performed by two authors, and the methodology and statistical analysis of each study were assessed.

RESULTS

Eight studies were included in this systematic review. Two reported increased incidence of GERD after PEG. However, neither was of high methodological quality. The remaining six reported no change or decreased GERD. Nonetheless, few demonstrated rigorous methodology.

CONCLUSIONS

The current evidence examining the effect of PEG insertion on GERD has been inconsistent and is not of high quality and therefore is unconvincing, preventing a definitive conclusion. Overall, the available literature on this topic does not demonstrate a causal effect of PEG insertion on GERD.

Clinical outcome after percutaneous endoscopic gastrostomy in children with malignancies

Percutaneous endoscopic gastrostomies (PEG) are little-used in pediatric oncology. We evaluated complications and efficacy of PEGs in children with malignancies in a retrospective case series. Outcome measures were infection and weight gain. Sixteen PEGs were inserted in 14 patients (mean age 10.3 years; SD 5.6). Sixteen wound infections occurred in nine children (3.7 episodes/1,000 days). Mean weight-for-age z-score fell from diagnosis to PEG placement (-0.68 (SD 1.2) to -1.32 (SD 1.26); P < 0.001) but stabilized afterward. Two (12%) were removed early. PEG placement reversed early weight loss and infectious complications did not usually lead to early PEG removal.

Morbidity and mortality after percutaneous endoscopic gastrostomy in children with neurological disability

BACKGROUND AND AIM

Gastrostomy placement has become an integral mechanism for delivering nutritional support to children with severe neurological disability. Its impact on gastroesophageal reflux and mortality remains contentious. We examined the morbidity and long-term mortality of a group of children with severe neurological disability after percutaneous endoscopic gastrostomy (PEG).

METHODS

We retrospectively identified all children with severe neurological disability who had a PEG at the Royal Children's Hospital in Melbourne between 1990 and 1997. Data were obtained from medical records.

RESULTS

Ninety-eight children with neurological disability (M:F 1.8:1.0; median age 3.5 years, interquartile range 1.1-8.7 years) had an initial PEG in this period and were able to be followed for 6-14 years. As a group, they were underweight for their age with a Z score at PEG of -3.52 (SD 3.33), but had increased weight-for-age Z scores by 1.05 after a mean period of 6.1 months. Fourteen subsequently required fundoplication for reflux. Mortality rates were 11% after 1 year, 21% after 2 years, 27% after 3 years and 39% after 13 years. Mortality was increased in those children who were older at the time of PEG (P = 0.06). Gastroesophageal reflux, underweight-for-age and gender were not significantly related to mortality.

CONCLUSION

Children with severe neurological dysfunction who require gastrostomy feeding have a substantial long-term mortality, but this may be unrelated to PEG placement.

Factors affecting clinical outcome in gastrostomy-fed children with cystic fibrosis

In order to assess the effects of gastrostomy feeding on nutritional status, respiratory function, and survival in children with cystic fibrosis (CF), we studied all patients undergoing gastrostomy between 1989-1997 at the Royal Children's Hospital, Melbourne. Clinical information was collected from medical records, including serial measurements of weight-for-age standard deviation scores (WAZ) and forced expired volume in 1 sec (FEV1) (percent predicted). Measurements were compared for 2 years before and 2 years after gastrostomy placement. Data on gastroesophageal reflux (GER), adherence to the gastrostomy feeding program, and sputum culture were also assessed. Of 37 children (22 male; mean age, 11.6 +/- 4.8 years; range, 3-20), 11 died during the study period (7 female, 4 male). Female patients were more likely to die within 2 years of gastrostomy placement (OR = 3.9; 95% CI, 0.72-23.2; P = 0.07). Mortality was significantly associated with a WAZ score < -2 (OR = 10.7; 95% CI, 1.07-466.6; P = 0.02) and predicted FEV1 < 50% (OR = 10.8; 95% CI, 1.07-512.9; P = 0.02) at time of gastrostomy. Patients with clinical evidence of GER (n = 11) had significantly lower weight gain after gastrostomy (delta WAZ, -0.32 +/- 0.26 vs. 0.03 +/- 0.39; P = 0.03). In conclusion, the presence of advanced lung disease, GER, and female gender were factors associated with a poor clinical outcome after gastrostomy placement.

Late-onset complications of percutaneous endoscopic gastrostomy in children

PURPOSE

The aim of this study was to report the late morbidity of percutaneous endoscopic gastrostomy (PEG) in a pediatric population and to identify possible risk factors for complications developing after PEG insertion.

METHODS

A PEG was placed in 110 children between 1 May 1990 and 1 January 1997 using the pull technique. A retrospective study of late-onset complications was performed, with a follow-up period ranging from 1 to 8 years. All the complications occurring more than 6 days after PEG insertion were recorded, except for gastrostomy tube obstruction and accidental tube dislodgement.

RESULTS

The prevalence of late-onset complications related to PEG in our patients varied from 3.8 to 4.4 per 10 5 days. The overall rate of late-onset complications was 44% (48 complications observed in 29 patients [26%]). Seventy-five percent of the complications appeared during the first 2 years after PEG insertion. Nine different types of complication have been identified: intragastric buried or extruded gastrostomy (n = 24), gastric metaplasia granulation tissue around the site of gastrostomy (n = 8), intragastric pseudotumoral proliferative gastric mucosa (n = 4), intragastric mucosal ulceration (n = 3), cutaneous necrosis (n = 3), cologastric fistula (n = 2), gastrostomy closure delay after tube removal (n = 2), subcostal neuralgia (n = 1), and peritonitis (n = 1). Wilcoxon and chi-square tests were used to compare the clinical characteristics of the patients and the type of material used in the two populations, with and without complications. No clinical risk factor for the development of complications could be identified. Intragastric buried or extruded gastrostomy appeared more frequently with the use of one type of button than with the use of tubes.

CONCLUSIONS

The authors' experience suggests that PEG is associated with significant late morbidity, which is mainly observed within the first 2 years after PEG insertion. However, no risk factor for the development of such complications could be identified.

The technology-dependent child

Improvements in the provision of oxygen, mechanical ventilation, tracheostomy care, enteral and parenteral nutrition, and dialysis have expanded the population of technology-dependent children. This article attempts to review pertinent points regarding these services, including common complications. Primary care and subspecialty physicians must smooth the transition of these children to the home environment, but a comprehensive team approach is necessary for the recognition of medical complications and provision of appropriate family teaching and psychosocial supports.

Substitute decision-making: measuring individually mediated sources of uncertainty

One aspect of O'Connor's Decisional Conflict Scale [O'Connor, A.M., Validation of a decisional conflict scale, Med. Decis. Making 15 (1995) 25-30] is the assessment of selected factors (perceived lack of information, undue social pressure, lack of support from others, and lack of clarity about personal values) that are believed to contribute to decisional uncertainty. This study explored the appropriateness of this uncertainty measure in the substitute decision-making context. Forty-nine mothers deciding on gastrostomy tube insertion for their children completed the scale, and also provided verbal reports about the contributory factors. For each of the four factors, relatively high-, moderate-, and low-scoring sub-groups were identified; then the associated verbal reports were examined for across-sub-group differences. Differences in verbal reports about information (chi 2 = 6.990, P = 0.0082), perceived pressure (chi 2 = 8.377, P = 0.0038), social support (chi 2 = 5.573, P = 0.0182), and perceived gains and losses (chi 2 = 3.85, P = 0.0499; chi 2 = 5.76, P = 0.0164) were observed, implying consistency between quantitative scores and verbal reports. This quantitative/qualitative hybrid approach may be clinically useful for assessing individually mediated factors contributing to decision uncertainty, and for evaluating therapeutic interventions in other substitute decision-making contexts.

Mothers' experiences caring for children with disabilities who require a gastrostomy tube

In this qualitative study, mothers' experiences of feeding children with severe disabilities by a gastrostomy tube are described. Twelve mothers each participated in one, open-ended, home interview. Mothers gave detailed accounts of their activities and the tremendous stress involved in feeding the children. They described spending enormous time and energy seeking confirmation of the feeding problem and devising extraordinary practices to ensure the child's survival before "giving in" to the gastrostomy tube. Following gastrostomy tube insertion, they initially felt relief and disappointment, before customizing feeding and moving on. Mothers' suggestions for improving professional services are discussed along with implication for practice and research.

Peritonitis following percutaneous gastrostomy in children: management guidelines

BACKGROUND

To establish the incidence, timing and outcome of peritonitis following percutaneous gastrostomy (PEG) insertion in children.

METHODS

Patients developing peritonitis after PEG insertion during a 5-year period (1990-95) were identified. Variables analysed included clinical presentation, management, operative findings and outcome.

RESULTS

One hundred and twenty paediatric patients received 130 PEG in the 5-year period. Eight children developed peritonitis: 4 within 24 h of PEG insertion and 4 following routine PEG tube change (3-18 months later). All four patients developing early peritonitis underwent laparotomy in whom three had sustained major damage to adjacent viscera. The fourth patient had a negative laparotomy, but died from continued overwhelming sepsis. All four patients who developed peritonitis after a routine tube change underwent a tube contrast study. In two children a gastrocolic fistula was identified and surgically repaired. Contrast studies in two patients detected an intraperitoneal leak. This problem resolved with conservative management in both cases.

CONCLUSIONS

Peritonitis immediately following PEG insertion is rarely due to the air leakage during insertion (benign pneumoperitoneum) and warrants early laparotomy to identify and correct the likely associated visceral trauma. Following PEG tube change peritonitis may result from stomal separation or tube malposition and an urgent study is indicated to identify the cause.

Gastroesophageal reflux and Nissen fundoplication following percutaneous endoscopic gastrostomy in children

BACKGROUND

Abnormal gastroesophageal reflux after percutaneous endoscopic gastrostomy is a serious problem in neurologically impaired children. Protective fundoplication has been advocated. Whether esophageal pH monitoring before percutaneous endoscopic gastrostomy will predict later problems with gastroesophageal reflux is unclear.

METHODS

Eighty-five mostly neurologically impaired pediatric patients who underwent percutaneous endoscopic gastrostomy were studied retrospectively regarding complications, success of nutritional rehabilitation, and the incidence of pathologic gastroesophageal reflux. Follow-up period was 1 to 4 years. Twenty-four-hour esophageal pH monitoring was performed in 46 patients before percutaneous endoscopic gastrostomy.

RESULTS

There were no deaths. Two major complications occurred that required surgical intervention, and 14 minor complications occurred related to the procedure. Z-scores for weight increased significantly after percutaneous endoscopic gastrostomy. pH probe results were normal in 22 patients (group 1). Five required medical treatment for gastroesophageal reflux after percutaneous endoscopic gastrostomy, but only 1 (5%) later required Nissen fundoplication. pH probe results were abnormal in 24 patients (group 2). Nineteen required medical therapy for gastroesophageal reflux, and 7 (29%) later needed fundoplication (p < 0.05, incidence of fundoplication group 1 vs. group 2). Improvement in Z-scores was similar in patients requiring and not requiring fundoplication.

CONCLUSIONS

Percutaneous endoscopic gastrostomy is a safe and effective technique for long-term nutritional support in children. Abnormal gastroesophageal reflux is common. Normal findings in an esophageal pH study before percutaneous endoscopic gastrostomy may be predictive of a favorable outcome with respect to gastroesophageal reflux. This is in contrast to patients with abnormal results in pH studies before percutaneous endoscopic gastrostomy of whom a relatively large percentage may later require fundoplication. Improved nutritional status after percutaneous endoscopic gastrostomy does not appear to have an impact on the severity of gastroesophageal reflux.

Complications following percutaneous endoscopic gastrostomy and subsequent catheter replacement in children and young adults

BACKGROUND

Percutaneous endoscopic gastrostomy has gained wide acceptance for patients who require prolonged tube feeding support. We sought to identify complications and associated risk factors of endoscopic gastrostomy and subsequent catheter replacement in pediatric patients.

METHODS

Medical records were reviewed for 137 patients. Odds ratios were calculated for complications related to patient age, weight, weight-for-age Z score, and principal diagnosis.

RESULTS

Seventeen patients (12.4%) developed significant complications after gastrostomy: cellulitis occurred in 10 patients (7.3%); other complications included gastrocolic fistula (2), duodenal hematoma (1), complicated pneumoperitoneum (1), necrotizing fasciitis (1), gastric perforation (1), and catheter migration (1). Patients with cancer had significantly greater odds for developing a wound infection, and patients with AIDS had significantly greater odds for total complications. A trend toward increased wound infection was observed in patients with cardiac disease. Age, weight, and weight-for-age Z score were not associated with adverse outcome. Two complications occurred in 85 patients (2.4%) after gastrostomy catheter replacement.

CONCLUSIONS

Pediatric patients with cancer and AIDS are at increased risk for complications after endoscopic gastrostomy regardless of age, weight, or nutritional status. Infrequent yet life-threatening complications may occur after replacement of initial gastrostomy catheter.

How to avoid complications during percutaneous endoscopic gastrostomy

Percutaneous endoscopic gastrostomy (PEG) has advantages over open gastrostomy, and is an accepted technique for children. However, a number of technical problems may be encountered during insertion. This report identifies those problems and proposes precautions that can be taken to reduce their likelihood. Recognized major complications include esophageal injury, colonic perforation, wound infection, gastric erosion by the gastrostomy tube, and later symptomatic gastroesophageal reflux requiring correction by fundoplication.

Trends in the use of fundoplication in children with gastro-oesophageal reflux

OBJECTIVE

To document changing trends in the indications for fundoplication in children with gastro-oesophageal reflux and to identify the main shortcomings and complications of the procedure.

METHODOLOGY

Retrospective review of 405 consecutive children undergoing fundoplication between 1978 and 1992 inclusive.

RESULTS

Trends in the indications for fundoplication related to broadening of its use in those with severe neurological impairment and uncontrolled reflux, and to changes in the management of patients in the neonatal period. Complications included unwrapping with recurrence of reflux, hiatal hernia, adhesive small bowel obstruction, dumping syndrome, post-operative persistence of oesophageal stricture, excessively tight wrap and poor oesophageal clearance (mostly in oesophageal atresia patients).

CONCLUSIONS

This study identified those patients most likely to develop complications following fundoplication. This may assist in the pre-operative assessment of the likely benefit of fundoplication in children who often have other complex problems.
