Comparison of complications between endoscopic and percutaneous replacement of percutaneous endoscopic gastrostomy tubes

Clinical Practice Guideline for Percutaneous Endoscopic Gastrostomy

With an aging population, the number of patients with difficulty swallowing due to medical conditions is gradually increasing. In such cases, enteral nutrition is administered through a temporary nasogastric tube. Long-term use of a nasogastric tube leads to various complications and a decreased quality of life. Percutaneous endoscopic gastrostomy (PEG) is the percutaneous placement of a tube into the stomach, aided endoscopically, which may be an alternative to a nasogastric tube when enteral nutritional is required for 4 weeks or more. This paper is the first Korean clinical guideline for PEG. It was developed jointly by the Korean College of Helicobacter and Upper Gastrointestinal Research and led by the Korean Society of Gastrointestinal Endoscopy. These guidelines aimed to provide physicians, including endoscopists, with the indications, use of prophylactic antibiotics, timing of enteric nutrition, tube placement methods, complications, replacement, and tubes removal for PEG based on the currently available clinical evidence.

Safety of Prophylactic Anticoagulation During Bedside Procedures: A Prospective Multicenter Observational Study

BACKGROUND

Bedside percutaneous dilatational tracheostomy (PDT) and percutaneous endoscopic gastrostomy (PEG) are common procedures performed in the intensive care unit (ICU). Venous thromboembolism (VTE) prophylaxis is frequently prescribed to ICU patients and it remains unclear whether pre-procedure discontinuation is necessary.

METHODS

This multi-center prospective observational study aimed to describe bleeding rates in patients undergoing bedside PEG or PDT who did or did not have VTE prophylaxis held. Decision to hold prophylaxis was made by the operating physician. The primary endpoint was the rate of peri-procedural bleeding complications. Secondary endpoints included quantification of held doses in the peri-procedural period, rate of venous thromboembolism, and characteristics associated with having prophylaxis held.

RESULTS

91 patients were included over a 2-year period. Patients were on average aged 54 years, 40% female, mostly admitted to the trauma service (59%), and most commonly underwent bedside PDT (59%). Overall, 21% of patients had doses of pre-procedure prophylaxis held. Bleeding events occurred in 1 patient (1.4%) who had prophylaxis continued and in 1 patient (5.0%) who had prophylaxis held, a rate difference of 3.6% (95% CI-9.5%, 16.7%). One bleeding event was managed with bedside surgical repair and one with blood transfusion. There were 10 VTE events, all of whom had prophylaxis continued during the pre-procedure period but 3 had prophylaxis held after the procedure.

CONCLUSIONS

Bleeding complications were rare and did not significantly differ depending on whether prophylaxis was held or not. Future research is required to confirm the lack of risk with continuing prophylaxis through bedside procedures.

Percutaneous endoscopic gastrostomy tube replacement after head and neck surgery: A case report

INTRODUCTION

Percutaneous endoscopic gastrostomy (PEG) has been available since the 1980s. Routine replacement is conducted at bedside with relatively few complications. Two replacement methods have come into practice: the percutaneous method and the endoscopic method. The laparoscopic method has recently become favorable in the pediatric population.

PRESENTATION OF CASE

Herein, we describe a situation in which a gastrostomy tube was replaced at bedside on a patient with previous head and neck surgery for lingual cancer. The percutaneous traction method was used, and gastrostomy tube replacement into the gastric lumen could not be confirmed on subsequent imaging. The patient was ultimately taken to surgery for an open procedure where it was discovered that initial PEG placement had traversed the small bowel mesentery en route to the gastric lumen.

DISCUSSION

The PEG tube is not a permanent device and routine exchange every 6-12 months is recommended. The percutaneous method and endoscopic method for gastrostomy tube replacement have both been used routinely, each with their set of complications. A third technique, laparoscopic placement, is the preferred modality in the pediatric population. Advantages are twofold: direct visualization of the stomach, thus eliminating inadvertent hollow viscus injury, and applicability in infants too small to undergo endoscopy necessary for PEG tube placement.

CONCLUSION

Consideration for laparoscopic placement or replacement in the head and neck cancer patient population, in which interval endoscopy is impossible, is thus advocated.

Multicenter cohort study of patients with buried bumper syndrome treated endoscopically with a novel, dedicated device

BACKGROUND AND AIMS

Buried bumper syndrome (BBS) is a rare adverse event of percutaneous endoscopic gastrostomy (PEG) placement in which the internal bumper migrates through the stomal tract to become embedded within the gastric wall. Excessive tension between the internal and external bumpers, causing ischemic necrosis of the gastric wall, is believed to be the main etiologic factor. Several techniques for endoscopic management of BBS have been described using off-label devices. The Flamingo set is a novel, sphincterotome-like device specifically designed for BBS management. We aimed to evaluate the effectiveness of the Flamingo device in a large, homogeneous cohort of patients with BBS.

METHODS

A guidewire was inserted through the external access of the PEG tube into the gastric lumen. The Flamingo device was then introduced into the stomach over the guidewire. This dedicated tool can be flexed by 180 degrees, exposing a sphincterotome-like cutting wire, which is used to incise the overgrown tissue until the PEG bumper is exposed. A retrospective, international, multicenter cohort study was conducted on 54 patients between December 2016 and February 2019.

RESULTS

The buried bumper was successfully removed in 53 of 55 procedures (96.4%). The median time for the endoscopic removal of the buried bumper was 22 minutes (range, 5-60). Periprocedural endoscopic adverse events occurred in 7 procedures (12.7%) and were successfully managed endoscopically. A median follow-up of 150 days (range, 33-593) was performed in 29 patients (52.7%), during which no significant adverse events occurred.

CONCLUSIONS

Through our experience, we found this dedicated novel device to be safe, quick, and effective for minimally invasive, endoscopic management of BBS.

Complications and early mortality in percutaneous endoscopic gastrostomy placement in lombardy: A multicenter prospective cohort study

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) is the most common endoscopic procedure used to provide nutritional support.

AIM

To prospectively evaluate the mortality and complication incidences after PEG insertion or replacement.

METHODS

All patients who underwent PEG insertion or replacement were included. Details on patient characteristics, ongoing therapies, comorbidities, and indication for PEG placement/replacement were collected, along with informed consent form signatures. Early and late (30-day) complications and mortality were assessed.

RESULTS

950 patients (47.1% male) were enrolled in 25 centers in Lombardy, a region of Northern Italy. Patient mean age was 73 years. 69.5% of patients had ASA status 3 or 4. First PEG placement was performed in 594 patients. Complication and mortality incidences were 4.8% and 5.2%, respectively. The most frequent complication was infection (50%), followed by bleeding (32.1%), tube dislodgment (14.3%), and buried bumper syndrome (3.6%). At multivariable analysis, age (OR 1.08 per 1-year increase, 95% CI, 1.0-1.16, p = 0.010) and BMI (OR 0.86 per 1-point increase, 95% CI, 0.77-0.96, p = 0.014) were factors associated with mortality. PEG replacement was carried out in 356 patients. Thirty-day mortality was 1.8%, while complications occurred in 1.7% of patients.

CONCLUSIONS

Our data confirm that PEG placement is a safe procedure. Mortality was not related to the procedure itself, confirming that careful patient selection is warranted.

To Pull or to Scope: A Prospective Safety and Cost-effectiveness of Percutaneous Endoscopic Gastrostomy Tube Replacement Methods

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) tubes are routinely used as an effective method for providing enteral nutrition. The need for their exchange is common.

GOALS

We aimed to examine the comparative safety and cost-effectiveness of PEG percutaneous counter-traction "pulling" approach or by endoscopically guided retrieval.

STUDY

A prospective 215 consecutive patients undergoing PEG tube insertion were included. Fifty patients in total were excluded. The patients were examined for demographics, indications for PEG replacement, as well as procedure-related complications and procedural costs.

RESULTS

Group A included 70 patients (42%) with PEG tubes replaced endoscopically, whereas group B included 95 patients (58%) with PEG tubes replaced percutaneously. Baselines characteristics were similar between the 2 groups (P=NS). Group A and group B had similar immediate complication rates including 4 patients in group B (4.2%), and 2 patients in group A (2.8%) (P=0.24). Complications included a conservatively managed esophageal perforation, and self-limited mild bleeding groups A and group B, respectively. The mean procedure cost was significantly higher in the endoscopic PEG replacement group compared with the percutaneous PEG replacement group ($650 vs. $350, respectively).

CONCLUSION

Percutaneous PEG replacement appears as safe as endoscopic PEG replacement, however, percutaneous tube exchange is less costly.

Percutaneous endoscopic gastrostomy. Indications, care and complications

Percutaneous endoscopic gastrostomy (PEG) is an effective and safe method for nutritional support in patients with malnutrition and impossibility of oral intake with an estimated survival higher than the months that require enteral nutrition beyond four weeks. The main indications include neoplasms of the upper air-digestive tract and neurological diseases, with dementia currently considered a controversial indication. Anatomical alterations and infectious diseases are the most frequent contraindications. There are different endoscopic techniques; the most widely used being the "pull" method, with a low mortality. Complications are more frequent in patients with multiple pathologies and the elderly. Wound infection, extraction of the tube, tube blockage and bronchoaspiratory pneumonia are the most prevalent complications. Adequate prior preparation of the patient and exhaustive maintenance of the tube can reduce the appearance of these.

[Clinical Course of Percutaneous Endoscopic Gastrostomy: A Single-center Observational Study]

Background/Aims

Percutaneous endoscopic gastrostomy (PEG) is a widely used method for long-term tube feeding. This study aimed to investigate the clinical characteristics and outcomes of patients who utilized long-term feeding tube via PEG.

Methods

The medical records of 137 patients who underwent PEG tube insertion at Ewha Womans University Mokdong Hospital between January 2002 and December 2013 were reviewed.

Results

PEG was indicated most frequently for cerebrovascular accidents (66 patients, 48.2%), followed by head and neck cancer (20 patients, 14.6%), and Parkinson's disease (10 patients, 7.3%). The tubes were endoscopically inserted in 133 patients (97.1%); 4 patients (2.9%) underwent radiologic intervention. The tubes of 90 patients (65.7%) were exchanged at least once during the follow- up period. At the first exchange, 71 patients (78.9%) had their tubes exchanged by endoscopy, 24 patients (16.7%) by manually, and 4 patients (4.4%) by radiologic intervention. Of the 61 patients (44.5%) who had their tubes exchanged twice, 44 patients (72.1%) changed their tubes by endoscopic exchange, 13 patients (21.3%) by manually, and 4 patients (4.4%) via radiologic intervention. The mean time interval between the initial insertion and the first exchange was 9.83±6.19 months, and that between the initial insertion and the second exchange was 10.7±6.25 months. Of all the 137 patients, acute complications at initial insertion occurred in only 18 patients (13.1%), with insertion site infection (9 patients, 6.6%) being the most common acute complication.

Conclusions

PEG appears to be a safe procedure for providing long-term tube feeding. Our results may help to develop strategies for further management of subjects receiving feeding tubes via PEG.

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.

Improved method of gastrostomy tube replacement using a small-caliber transnasal endoscope

CONCLUSION

Gastrostomy tube replacement using a new approach through the abdominal-wall stoma with a small-caliber trans-nasal endoscope is feasible, fast, and safe compared with the trans-oral approach.

OBJECTIVES

To evaluate the feasibility of a new technique using a trans-nasal endoscope for gastrostomy tube replacement.

METHODS

Between June 2005 and December 2013 in the Peking University Third Hospital, 69 patients underwent gastrostomy tube replacement using the trans-oral approach (conventional method) or a small-caliber trans-nasal endoscope inserted through the abdominal-wall stoma (new method). A retrospective review was performed of the medical records of those patients, including demography and information about the surgical procedure and any complications. Patients were classified into the conventional group and the new method group. Descriptive statistics for all continuous variables were mean ± standard deviation and for categorical variables were number and percentage.

RESULTS

Gastrostomy tube replacement was achieved in 69 of 69 cases (100%); 23 of these procedures were performed using the new method. The surgery time with the conventional method (8.3 ± 2.0 min) was significantly longer than with the new method (6.0 ± 0.9 min, p < 0.001). With the conventional method, there was one patient (2%) with post-operative fever and skin infection; no complications occurred with the new method.
