Percutaneous endoscopic gastrostomy with and without jejunal extension in patients with amyotrophic lateral sclerosis

Safety of Percutaneous Endoscopic Jejunostomy Placement Compared With Surgical and Radiologic Jejunostomy Placement: A Nationwide Inpatient Assessment

BACKGROUND AND AIMS

We compared the safety and outcomes of percutaneous jejunostomy tubes placed endoscopically (PEJ), fluoroscopically by interventional radiology (IR-jejunostomy), and open jejunostomy placed surgically (surgical jejunostomy).

METHODS

Using the Nationwide Readmissions Database, we identified hospitalized patients who underwent a jejunostomy from 2016 to 2019. Selected patients were divided into 3 cohorts: PEJ, IR-jejunostomy, and surgical jejunostomy. Adjusted odds ratios (OR) for adverse events were calculated using multivariable logistic regression analysis.

RESULTS

A total of 6022 (65.2±9.8 y) surgical jejunostomy patients, 3715 (63.6±11.0 y) endoscopic jejunostomy patients, and 14,912 (64.8±11.6 y) IR-jejunostomy patients were identified. Compared with surgery, PEJ patients were 32% less likely to experience postprocedure complications (OR: 0.68; 95% CI: 0.58-0.79, P <0.001) while IR-jejunostomy patients were 17% less likely to experience complications (OR: 0.83; 95% CI: 0.73-0.94, P <0.001); test of proportion showed that endoscopy had significantly fewer total adverse events compared with IR ( P <0.001). For individual complications, compared with surgery, the odds of intestinal perforation using PEJ and IR, respectively, were 0.26 (95% CI: 0.14-0.49, P <0.001) and 0.31 (95% CI: 0.21-0.47, P <0.001), for postprocedure infection 0.32 (95% CI: 0.20-0.50; P <0.001) and 0.61 (95% CI: 0.45-0.83; P =0.001); and for hemorrhage requiring blood transfusion 0.71 (95% CI: 0.56-0.91; P =0.005) and 0.75 (95% CI: 0.61-0.91; P =0.003).

CONCLUSIONS

Endoscopic placement of percutaneous jejunostomy tubes (PEJ) in inpatients is associated with significantly lower risks of adverse events and mortality compared with IR and surgical jejunostomy.

Effectiveness and safety of an atropine/midazolam and target controlled infusion propofol-based moderate sedation protocol during percutaneous endoscopic transgastric jejunostomy procedures in Parkinson's disease: a real-life retrospective observational study

Patients with Parkinson's disease (PD), often elderly with various comorbidities, may require a continuous intestinal infusion of carbidopa/levodopa gel by the placement of a percutaneous endoscopic gastrostomy (PEG) with a jejunal tube (PEG-J) to improve their motor outcome and quality of life. However, it is unclear what is the best procedural sedation protocol for PEG-J procedures. Fifty patients with PD and indication for PEG-J procedure (implantation, replacement, removal) underwent, from 2017 to 2022, a sedation protocol characterized by premedication with atropine (0.01 mg/Kg i.v.), midazolam (0.015-0.03 mg/Kg i.v.) and induction with bolus propofol (0.5-1 mg/Kg i.v.) as well as, finally, sedation with continuous infusion propofol (2-5 mg/Kg/h i.v.) by Target Controlled Infusion (TCI) technique. Ninety-eight per cent of patients experienced no intraprocedural or peri-procedural adverse events. All the procedures were technically successful. A good discharge time was recorded. The vital parameters recorded during the procedure did not vary significantly. A PEG-J procedure conducted within 30 min showed a significant advantage over end-tidal carbon dioxide (EtCO2). Indeed, the latter showed some predictive behavior (OR: 1.318, 95% CI 1.075-1.615, p = 0.008). In the real world, this sedation protocol showed a good safety and effectiveness profile, even with reduced doses of midazolam and a TCI propofol technique in moderate sedation.

Enteral tube feeding for amyotrophic lateral sclerosis/motor neuron disease

BACKGROUND

Maintaining adequate nutrition is critical for people with amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND). Enteral tube feeding is offered to people experiencing difficulty swallowing (dysphagia) to prevent weight loss and aspiration pneumonia. Among the types of enteral tube feeding, percutaneous endoscopic gastrostomy (PEG) is the typical procedure offered to people with ALS and will be mainly discussed here.

OBJECTIVES

To examine the effectiveness of percutaneous endoscopic gastrostomy or other enteral tube feeding in people with ALS, compared to oral feeds without enteral tube feeding on: 1. survival; 2. nutritional status; 3. quality of life. To examine the incidence of minor and major complications of percutaneous endoscopic gastrostomy (PEG) and other enteral tube feeding procedures in people with ALS.

SEARCH METHODS

On 3 January 2020 and 6 February 2021, we searched the Cochrane Neuromuscular Specialised Register, CENTRAL, MEDLINE. Embase, ClinicalTrials.gov and WHO ICTRP. We screened the results to identify randomized controlled studies on enteral tube feeding in ALS. We reviewed all references from the search in published articles to identify any additional references.

SELECTION CRITERIA

We included randomized controlled trials (RCTs), quasi-RCTs, and cross-over trials evaluating the effectiveness and complications of PEG or other enteral tube feeding placement in ALS.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We found no RCTs or quasi-RCTs comparing the effectiveness of enteral tube feeding versus oral feeds without enteral tube feeding.

AUTHORS' CONCLUSIONS

There are no RCTs or quasi-RCTs to indicate whether enteral tube feeding is effective compared to continuation of oral feeding for any of the outcome measures. Such RCTs are very unlikely to be performed for ethical reasons. RCTs evaluating the effect of different enteral tube insertion techniques and timings of tube placement on survival and quality of life of people with ALS dysphagia are feasible and warranted.

Direct percutaneous endoscopic jejunostomy (DPEJ) and percutaneous endoscopic gastrostomy with jejunal extension (PEG-J) technical success and outcomes: Systematic review and meta-analysis

Background and study aims  Endoscopic methods of delivering uninterrupted feeding to the jejunum include direct percutaneous endoscopic jejunostomy (DPEJ) or PEG with jejunal extension (PEG-J), validated from small individual studies. We aim to perform a meta-analysis to assess their effectiveness and safety in a variety of clinical scenarios. Methods  Major databases were searched until June 2021. Efficacy outcomes included technical and clinical success, while safety outcomes included adverse events (AEs) and malfunction rates. We assessed heterogeneity using I ² and classic fail-safe to assess bias. Results  29 studies included 1874 patients (983 males and 809 females); mean age of 60 ± 19 years. Pooled technical and clinical success rates with DPEJ were 86.6 % (CI, 82.1-90.1, I ² 73.1) and 96.9 % (CI, 95.0-98.0, I ² 12.7). The pooled incidence of malfunction, major and minor AEs with DPEJ were 11 %, 5 %, and 15 %. Pooled technical and clinical success for PEG-J were 94.4 % (CI, 85.5-97.9, I ² 33) and 98.7 % (CI, 95.5-99.6, I ²  < 0.001). The pooled incidence of malfunction, major and minor AEs with DPEJ were 24 %, 1 %, and 25 %. Device-assisted DPEJ performed better in altered gastrointestinal anatomy. First and second attempts were 87.6 % and 90.2 %. Conclusions  DPEJ and PEG-J are safe and effective procedures placed with high fidelity with comparable outcomes. DPEJ was associated with fewer tube malfunction and failure rates; however, it is technically more complex and not standardized, while PEG-J had higher placement rates. The use of balloon enteroscopy was found to enhance DPEJ performance.

An overview of percutaneous endoscopic gastrostomy tube placement in the intensive care unit

Critically ill patients are at increased risk for malnutrition as they often have underlying acute and chronic illness, stress related catabolism, decreased appetite, trauma and ongoing inflammation. Malnutrition is recognized as a leading cause of adverse outcomes, higher mortality, and increased hospital costs. Percutaneous endoscopic gastrostomy (PEG) tubes provide a safe and effective route to provide supplemental enteral nutrition to these patients. PEG placement has essentially replaced surgical gastrostomy as the modality of choice for longer term feeding in patients. This is a highly prevalent procedure with 160,000 to 200,000 PEG procedures performed each year in the United States. The purpose of this review is to provide an overview of current knowledge and practice standards with regards to placement of PEG tube in the Intensive Care Unit (ICU). When a patient is considered for a PEG tube, it is important to evaluate the treatment alternatives and identify the best option for each patient. In this review, we provide the advantages and disadvantages of various feeding modalities and devices. We review the indications and contraindications for PEG tube placement as well as the risks of this procedure. We then describe in detail the per-oral pull, per-oral push, and direct percutaneous techniques for PEG tube placement. Additionally, we review the feasibility of having interventional pulmonologists place PEG tubes in the ICU.

Percutaneous gastrostomy in amyotrophic lateral sclerosis: a review

Amyotrophic lateral sclerosis (ALS) causes dysphagia and consequent poor nutrition. Sometimes enteral feeding is offered. Percutaneous endoscopic gastrostomy (PEG) is currently the technique of choice for enteral nutrition of these patients. This systematic review addresses the role of PEG and other enteral feeding techniques in maintaining ALS patients' survival and quality of life and in identifying prognostic factors for survival, in order to optimize their usefulness. We also evaluated the mortality of enteral feeding in the first 30 days after each procedure and its complications. Studies were retrieved from Pubmed, Google Scholar, and Cochrane databases, using the relevant keywords, and by hand search. The inclusion criteria were prospective and retrospective designs of studies of people with clinically diagnosed ALS in whom gastrostomy or nasogastric enteral feeding were used in management, published in English. Studies with sample sizes <40, or which focused on a specific gastrostomy technique utilizing less than 30 subjects were excluded in order to avoid small sample bias. We conclude that PEG is safe and probably prolongs survival in non-malnourished ALS patients. However, older age at onset, marked loss of weight or reduced body mass index from symptomatic onset, and marked respiratory dysfunction negatively influence the outcome after PEG insertion. The currently available evidence does not meaningfully address the impact of PEG on quality of life in ALS. The literature about other enteral feeding techniques is insufficient for reliable conclusions. The optimum time for PEG insertion and preferences for specific gastrostomy techniques also require more investigation.

Paravertebral block for radiologically inserted gastrostomy tube placement in amyotrophic lateral sclerosis

INTRODUCTION

Radiologically inserted gastrostomy (RIG) placement in patients with amyotrophic lateral sclerosis (ALS) carries risks related to periprocedural sedation and analgesia. To minimize these risks, we used a paravertebral block (PVB) technique for RIG placement.

METHODS

We retrospectively reviewed patients with ALS undergoing RIG placement under PVB between 2013 and 2017.

RESULTS

Ninety-nine patients with ALS underwent RIG placement under PVB. Median (range) age was 66 (28 to 86) years, ALS Functional Rating Scale-Revised score was 27 (6 to 45), and forced vital capacity was 47% (8%-79%) at time of RIG placement. Eighty-five (85.9%) patients underwent RIG placement as outpatients, with a mean postanesthesia care unit stay of 2.3 hours. The readmission rate was 4% at both 1 and 30 days postprocedure.

DISCUSSION

PVB for RIG placement has a low rate of adverse events and provides effective periprocedural analgesia in patients with ALS, the majority of whom can be treated as outpatients.

Amyotrophic lateral sclerosis and anesthesia: a case series and review of the literature

PURPOSE

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to death due to respiratory failure. This report describes the perioperative characteristics of ALS patients who underwent procedures with anesthesia at our institution.

METHODS

We reviewed perioperative records of ALS patients who underwent procedures with anesthesia from January 1, 2014, through December 31, 2015.

RESULTS

Seventy-eight patients underwent 89 procedures (71 procedures with monitored anesthesia care and 18 with general anesthesia), including 45 gastrostomy tube placements and 18 bone marrow biopsies. Three patients had prolonged duration of postoperative intubation related to preexisting respiratory muscle weakness, and one patient with bilateral pneumothorax required tracheal reintubation for respiratory distress. Four patients had prolonged duration of hospitalization. Three patients were hospitalized for ALS-related complications, and one patient was hospitalized for respiratory distress when pneumoperitoneum developed after gastrostomy tube placement. Three of these patients died of complications attributable to ALS within 30 days of the procedure. Twenty-nine (32.6%) procedures required minimal sedation (e.g., bone marrow biopsy, cataract surgery) and were performed on an ambulatory basis.

CONCLUSION

When caring for patients with ALS, the perioperative team must be prepared to treat potentially complex medical conditions that may not be directly related to the procedure and anesthetic management. However, minor procedures performed with minimal sedation may be safely performed on an ambulatory basis.
