Percutaneous endoscopic gastrostomy tube replacement: A simple procedure?

The Pediatric Emergency Department Nurse and Gastrostomy Tube Replacement: How Safe Is it?

AIM

To review the outcomes of a nurse-only guideline for replacement of gastrostomy tubes (g-tubes) in a pediatric emergency department (ED) and compare rates of success, failure, length of stay (LOS), and return visits with that of ED physicians.

DESIGN

Nursing g-tube guidelines, created by a nurse educator and nursing council, were instigated on January 31, 2018. Variables examined included LOS, age at visit, return visit within 72 hours, reason for replacement, and any postplacement complications.

REVIEW METHODS

Data of g-tube placement by nurses and physicians were compared using t test or χ 2 analysis (IBM-SPSS version 20, New Orchard Road, Armonk, NY). The institutional review board determined the study to be exempt from human subjects. The STROBE checklist was used and completed accordingly.

DATA SOURCES

Chart abstraction and data were collected from January 1, 2011 through April 13, 2020, and medical records were obtained using International Classification of Diseases, Tenth Revision (ICD-10) codes for g-tubes: Z93.1, K94.23.

RESULTS

A total of 110 patients were included in our study. Fifty-eight underwent nursing-only replacements; 52 were replaced by physicians. Nurse replacement success rate was 98.3% with an average stay of 22 minutes. Physician success rate was 100% with an average stay of 86 minutes. The difference between nursing and physician LOS was 64.6 minutes. No patient in either group experienced postreplacement complications.

CONCLUSIONS

The initiation of nurse-only management of dislodged g-tubes was successful, safe, and had a shorter LOS when compared with physicians in the pediatric ED.

IMPACT

Our study determined the implications of nurse-only replacement of g-tubes in a pediatric ED. We found that nurses replacing g-tubes was equally safe and effective as physician counterparts. In addition, we found that it significantly reduced the LOS for patients, which has consequences on patient satisfaction and billing.

PATIENT/PUBLIC CONTRIBUTION

Nursing staff were trained in g-tube replacement using guidelines created by a nurse educator and nursing council. Patients either had their dislodged g-tubes replaced by the trained nurse or a physician and comparisons on the outcomes were made. Patients were aware of the study and consented to have their medical records accessed to make the data comparisons.

RELEVANCE TO CLINICAL PRACTICE

With more than 189,000 children in the United States relying on g-tubes, nursing staff will inevitably be involved in the care of patients with such a device. In addition, as pediatric EDs continue to develop longer and longer waiting times, we must learn how to better use our nursing staff for procedures within their scope and minimize LOS. Our research demonstrates the safety, feasibility, and general benefits of having the pediatric nursing staff replace g-tubes in the ED, and it is hoped that this will lead to beneficial policy changes.

‘Cut and push’ as an alternative to endoscopic retrieval of PEG type gastrostomy tubes

PURPOSE

Percutaneous Endoscopically placed Gastrostomy (PEG) tubes are frequently used in children. The traditional endoscopic method to remove/change the PEG device requires general anaesthesia in children. A minimally invasive alternative is the 'Cut and Push' method (C&P): avoiding the risks/wait times of general anaesthesia and reducing resource burden. Data regarding the safety/effectiveness of C&P in children are lacking with concerns raised about the possibility of gastrointestinal obstruction.

METHODS

We retrospectively reviewed all cases of PEG removal / change to button in children (< 18 years) between December 2020 and January 2022. Cases were identified from a prospectively maintained database and all cases of C&P included. Parents/carers were asked if the child had suffered any complications following C&P and if flange was visualised in stools.

RESULTS

During the time period, 27 PEGs were either removed or changed to button via C&P. The average waiting time for C&P was 14.29 days, significantly shorter than the minimum 6-month waiting time for elective endoscopy. Our evaluation revealed no complications of C&P at median 70 days (range 25-301). In three cases the flange was visualised in the stool, at 2 days, 3 days and 5 weeks following C&P respectively.

DISCUSSION

These data support the available literature suggesting C&P is an effective means to facilitate minimally invasive and prompt PEG removal/change to button in children. We recommend minimum weight and age parameters for this procedure and further evaluation of the safety and resource implications of this technique.

"Orphaned" Stomach-An Infrequent Complication of Gastric Bypass Revision

While generally safe, bariatric operations have a variety of possible complications. We present an uncommon complication after gastric bypass revision, namely the creation of an "orphaned" segment of remnant stomach that was left inadvertently in discontinuity, leading to recurrent intra-abdominal abscesses. Sinogram ultimately proved the diagnosis, and the issue was successfully treated using a combination of surgical and endoscopic methods to control the abscess and to allow internal drainage.

Severe Gastrointestinal Bleeding Following Gastrostomy Tube Replacement: A Case of an Unusual Presentation of Enterocutaneous Fistula

Gastrostomy tubes are widely used and provide an alternative route of enteral feeding when oral intake is not feasible. Previously, a surgical laparotomy was required for its placement, but percutaneous endoscopic gastrostomy and fluoroscopy-guided percutaneous radiological gastrostomy (PRG) techniques have widely replaced the surgical approach given their less invasive nature. Although the complications that might follow these procedures are usually minor, more severe complications can rarely occur. We describe a unique case of severe gastrointestinal bleeding in a patient who underwent PRG tube exchange reflecting an acute complication following an asymptomatic misplaced permanent gastrostomy tube.

Assessment of the effect of colored beverage on gastric returns after gastric tube replacement to enhance placement verification

BACKGROUND

Verification of appropriate placement of newly replaced gastrostomy tubes is essential prior to use to avoid potentially serious adverse events.

PROBLEM

A lack of standardized guidance regarding effective and practical means to verify placement exists. Aspiration or drainage of gastric-like contents is one mean suggested to help determine placement, yet when returns are minimal, this becomes challenging.

MATERIALS, METHOD, INTERVENTION

Oral ingestion or the instillation of a colored beverage prior to tube replacement was used in a midwestern healthcare clinical setting to enhance returns in both volume and color via the newly replaced gastrostomy tube. A retrospective review of this practice was conducted, which included 176 gastric tube replacements over 4 years.

RESULTS

A significant increase in volume of returns via the newly replaced tube was noted (P < .001) and a strong correlation of color to the ingested or consumed beverage was found with 95% of returns reflecting color tinting of the beverage or in many cases, strong color change to that of the beverage color.

CONCLUSION

Presented is a simple, cost-effective method that has shown to be clinically useful in assessing placement of newly replaced gastrostomy tubes that may be useful in other practices and settings.

Endoscopic rescue of early percutaneous endoscopy gastrostomy tube dislodgement

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) tube placement is one of the most common methods for establishing durable enteral access. Early PEG dislodgement occurs in < 5% of cases but typically prompts urgent surgical intervention to reestablish the gastrocutaneous tract and prevent intra-abdominal sepsis. To date, there is a single case report in the literature where successful endoscopic "rescue" of an early dislodged PEG tube negated the need for operative intervention. Here, we report our experience with a series of endoscopic PEG rescues for early dislodged PEG tubes.

METHODS

A retrospective analysis of cases was reviewed from two institutions. Patients with early PEG dislodgements underwent PEG rescue using a gastroscope and standard Ponsky "Pull" PEG techniques through the original tract.

RESULTS

Eleven patients were identified from the database and underwent PEG rescue after early PEG dislodgement. Mean operative time was 68 min, and there were no complications related to PEG rescue. PEG rescue permitted safe re-establishment of the gastrostomy tract while avoiding laparoscopic or open surgical intervention in hemodynamically stable patients. All patients tolerated the procedure well and were able to resume use of the PEG tubes shortly after intervention.

CONCLUSION

Endoscopic rescue represents a feasible noninvasive option for PEG tube replacement following early inadvertent PEG tube dislodgement in appropriate clinical settings.

Point-of-care ultrasound for confirmation of gastrostomy tube replacement in the pediatric emergency department

Gastrostomy tubes (G-tubes) are frequently used in children for feeding and nutrition. Complications related to G-tubes (and G-buttons) in children represent a common presentation to the emergency department (ED). G-tube replacement is usually performed by pediatric emergency medicine physicians. Misplacement may lead to tract disruption, perforation, fistula tract formation, or feeding into the peritoneum. Contrast-enhanced radiographs are traditionally used for confirmation. In addition to a longer length-of-stay, repeat ED visits result in repeated radiation exposure. The use of point-of-care ultrasound (POCUS) instead of radiography avoids this exposure to ionizing radiation. Here, we describe three patients who presented with G-tube complications in whom POCUS alone performed by pediatricians was used for confirmation of the tubes' replacement. Two children presented to the ED with G-tube dislodgement, and one child presented with a ruptured balloon. In all three cases, a new G-tube was replaced at the bedside using POCUS guidance without the need for further radiographic studies. There were no known ED or clinic returns for G-tube complaints over the next 30 days. This is the first report of pediatricians using POCUS to guide and confirm G-tube replacement in children. The success of these cases suggests the technique's feasibility. Future prospective studies are needed to evaluate the learning curves, diagnostic accuracy, ED length-of-stay, and use of confirmatory imaging.

Laparoscopic tubularized continent gastrostomy: an alternative to tube gastrostomies

Gastrostomy tubes, placed either endoscopically or laparoscopically, are the most widely used method to deliver enteral feeding to patients unable to be fed by mouth. Tube gastrostomy is quick and low cost and allows the health care professionals for a convenient route to deliver enteral nutrition to their patients. Nevertheless, bearing an indwelling gastric tube could not be as convenient for patients. Complications, such as bowel perforation, tube dislodgement, peristomal infection or bleeding occur in up to 17% of patients, and some other drawbacks of gastric tubes, such as peristomal pain, are often understated. We present our technique for laparoscopic creation of a tubularized continent gastrostomy, originally conceived for the emergency treatment of patients with a dislodged percutaneous endoscopic gastrostomy, to provide them with a reliable new route for gastric feeding. After healing, this gastrostomy does not need an indwelling tube to stay patent, requires only a light gauze dressing and can be used by intermittent catheterization at conventional feeding times during the day. Laparoscopic tubularized continent gastrostomy can be offered to patients as a reliable alternative to tube gastrostomy.

Micropattern-mediated apical guidance accelerates epithelial cell migration to improve healing around percutaneous gastrostomy tubes

Hypergranulation, bacterial infection, and device dislodgment are common complications associated with percutaneous gastronomy (PG) tube placement for enteral feeding largely attributable to delayed stoma tract maturation around the device. Stoma tract maturation is a wound-healing process that requires collective and complete migration of an advancing epithelial layer. While it is widely accepted that micropatterned surfaces enhance cell migration when cells are cultured directly on the substrate, few studies have investigated the influence of apical contact guidance from micropatterned surfaces on cell migration, as occurs during stoma tract formation. Here, we developed 2D and 3D in vitro epithelial cell migration assays to test the effect of various Sharklet micropatterns on apically-guided cell migration. The 2D modified scratch wound assay identified a Sharklet micropattern (+10SK50×50) that enhanced apical cell migration by 4-fold (p = 0.0105) compared to smooth controls over the course of seven days. The best-performing micropattern was then applied to cylindrical prototypes with the same outer diameter as a pediatric PG tube. These prototypes were evaluated in the novel 3D migration assay where magnetic levitation aggregated cells around prototypes to create an artificial stoma. Results indicated a 50% increase (p < 0.0001) in cell migration after seven days along Sharklet-micropatterned prototypes compared to smooth controls. The Sharklet micropattern enhanced apically-guided epithelial cell migration in both 2D and 3D in vitro assays. These data suggest that the incorporation of a Sharklet micropattern onto the surface of a PG tube may accelerate cell migration via apical contact, improve stoma tract maturation, and reduce skin-associated complications.

Management of early PEG tube dislodgement: simultaneous endoscopic closure of gastric wall defect and PEG replacement

A 53-year-old man with dysphagia underwent uneventful placement of a percutaneous endoscopic gastrostomy (PEG) tube for long-term enteral feeding access. 11 hours after the procedure, it was discovered that he had accidentally dislodged the feeding tube. On physical examination, he was found to have a benign abdomen without evidence of peritonitis or sepsis. He was observed overnight with serial abdominal examinations and nasogastric decompression. In the morning, he was taken back to the endoscopy suite where endoscopic clips were employed to close the gastric wall defect and a PEG tube was replaced at an adjacent site. The patient was fed 24 hours thereafter and discharged from the hospital 48 hours after the procedure. Early accidental removal of a PEG tube in patients without sepsis or peritonitis can be safely treated with simultaneous endoscopic closure of the gastrotomy and PEG tube replacement, resulting in earlier enteral feeding and shorter hospital stay.

The Buried Bumper Syndrome: A Catastrophic Complication of Percutaneous Endoscopic Gastrostomy

Percutaneous endoscopic gastrostomy (PEG) is a safe and widely used method of providing enteral nutrition in patients unable to tolerate per oral intake. Common complications include gastrointestinal bleeding, dislodgment, perforation, abdominal wall abscess, and aspiration. "Buried bumper syndrome" (BBS) is a rare but potentially fatal complication resulting in malfunction of the tube, gastric perforation, bleeding, and peritonitis. Gastroenterologists should be cognizant of the clinical presentation and treatment of a buried bumper. We report a case of a 56-year-old woman who presented with coffee-ground emesis and was managed with the placement of a gastro-jejunal tube.

Use of Point-of-Care Ultrasound to Guide Pediatric Gastrostomy Tube Replacement in the Emergency Department

The presentation of a pediatric patient to the emergency department for a malfunctioning or dislodged gastrostomy tube (G-tube) is not uncommon. As such, these tubes are often replaced at the bedside. Improper placement can result in a number of complications, including perforation, fistula tract formation, peritonitis, and sepsis. The current criterion standard method to confirm proper G-tube placement is contrast-enhanced radiography. However, point-of-care ultrasound may be an alternative method to guide and confirm pediatric G-tube replacement in the emergency department. We report a series of cases on this novel point-of-care ultrasound application.

Some Mushrooms are Hard to Digest: Gastrostomy Tube Exchange

Background

Percutaneous endoscopic gastrostomy (PEG) is an effective and safe mode of enteral nutrition for patients needing chronic enteric nutritional support. Exchanging PEG tubes may result in complications due to inexperience as well as due to lack of protocol.

Case Report

We encountered a 73 year-old female with unnoticed, accidently detached portion of the internal bumper of a PEG tube in the gastric lumen after a challenging gastrostomy tube exchange.

Conclusions

This case report discusses the complications associated with gastrostomy tube exchange and proposes a planned protocol for successful gastrostomy tube exchange.

Low Abdominal Wall Thickness May Predict Percutaneous Endoscopic Gastrostomy Complications

Although percutaneous endoscopic gastrostomy (PEG) tube placement is a common and safe procedure to provide enteral feeding, some patients develop complications. The aim of this study was to identify risk factors for the development of post-PEG complications. We hypothesized that patients with low albumin, diabetes, higher body mass index (BMI), thicker abdominal walls, or psychomotor agitation would have more complications. A 2-year retrospective review was performed on patients who received a PEG tube at a single institution. Variables collected included age, preoperative albumin, BMI, abdominal wall thickness (AWT), psychomotor agitation, pre-operative diabetes mellitus, and mortality. A total of 91 patients (70.3% male) were identified (mean age 58.7 years, SD 18.6). Seventeen patients (18.7%) had post-PEG complications and the 30-day mortality rate was 14.3 per cent. Mortality was not attributable to tube placement. Patients with complications weighed less (P = 0.005) and had a lower BMI (P = 0.010) than patients without complications. Additionally, patients with complications had significantly lower AWT (P = 0.02), mean AWT was 21.6 mm (SD 7.6) versus 27.6 mm (SD 8.1) in the noncomplication patients. AWT was the only factor independently associated with post-PEG complications (P = 0.047). There was no significant association between complications and mortality. Continued investigation on how to limit post-PEG complications remains imperative. In our population, lower AWT was independently associated with complications. Preoperative measurement of AWT by pre-procedural imaging can potentially be used to predict the risk of post-PEG complications.

Adult enteral device selection: which is the best for the patient?

Enteral feeding is considered to be a safe and effective way of providing nutrition to patients who are unable to meet their requirements orally. There are a number of enteral feeding devices, including naso-gastric and gastrostomy tubes, that allow access to the stomach for feeding. However, selecting the most appropriate device for a patient depends on a number of factors, including consideration of duration of feeding and the individual patient's clinical condition and social circumstances. In addition, the patient should always be included in decision making where possible. This article explores the decision-making process regarding selection of appropriate enteral feeding devices and applies this process to two patient case studies.

Percutaneous endoscopic gastrostomy tube replacement unexpected serious events

Percutaneous endoscopic gastrostomy tubes are replaced due to clogging, breaking, and dislodgement. There are potential complications associated with these procedures, including intraperitoneal placement of the tube and peritonitis, which can occur even in the presence of a well established stoma site. Herein we present a case series of 3 patients with mature gastrocutaneous tracks, who developed peritonitis following tube replacement. In the absence of a consensus or international guidelines regarding the management of patients requiring percoutaneous endoscopic gastrostomy tube replacement, emphasis should be given on prevention of severe adverse events and on early anticipation of their occurrence. Clinical experience indicates that recognition of high-risk procedures, selection of the appropriate replacement method and confirmation of correct tube placement can improve patients' safety and reduce the complications rate.
