Mortality risk factors after percutaneous gastrostomy: Who is a good candidate?

Complications and survival following percutaneous endoscopic gastrostomy tube placement

INTRODUCTION

Percutaneous endoscopic gastrostomy (PEG) is considered a safe and effective method for nutritional support in patients with malnutrition and swallowing impairment with an estimated survival of over two months. Some indications, such as advanced cognitive decline, contraindicate the technique.

MATERIALS AND METHODS

All patients who underwent PEG placement between January 2001 and May 2019 were included. Clinical data, indication, complications, and mortality were retrospectively analyzed.

RESULTS

A total of 648 patients (46.5% male, mean age 70±18.5 years) were included. The most common indications for PEG were advanced cognitive decline (31.5%) and cerebrovascular disease (18.8%). The mean follow-up was 12.07 months (IQR 3.27-34.73). 39.5% of patients experienced complications (systemic 17.9%, local 28.5%). The most frequent were bronchoaspiration (9.7%) and rupture/dysfunction (13.9%), respectively. The presence of early complications (HR 1.63 [1.20-2.21]) and age (HR 1.02 [1.01-1.02]) were associated with shorter survival time, while female sex was a protective factor (HR 0.78 [0.66-0.94]).

CONCLUSIONS

PEG is not without complications, with 39.5% of patients experiencing them. Patients with advanced dementia, male sex, older age, and systemic complications have lower survival following PEG placement.

Factors Associated With Short-Term Complications After Percutaneous Endoscopic Gastrostomy Tube Insertion: A Retrospective Cohort Study

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) tube placement is generally safe but is associated with a range of complications. Minor complications include infections, granuloma formation, leakage, and blockages, while major complications encompass aspiration pneumonia, hemorrhage, and more serious conditions such as necrotizing fasciitis and colonic fistula.

AIM

This study aimed to assess the rate of short-term complications within one month of endoscopic PEG insertion, focusing on their correlation with patient characteristics.

METHODOLOGY

This retrospective cohort study analyzed data from patients who underwent PEG insertion between January 2020 and December 2022. It evaluated the incidence of complications in relation to variables such as the indication for the procedure, the patient's immune status, albumin and CRP levels, and the setting of the procedure (inpatient vs. outpatient).

RESULTS

The study included 121 patients, with a mean age of 69.73 years, comprising 71 males (58.7%) and 50 females (41.3%). Neurological indications accounted for 64.5% of the cases. Notably, 67.8% of the patients were immunocompromised. Within 30 days of PEG insertion, 16.5% experienced complications, including GI bleeding (4.1%), infection at the PEG site (11.6%), and peritonitis (0.8%). Complications were significantly higher in immunocompromised patients and those with non-neurological indications. Higher serum albumin and lower CRP levels were associated with fewer complications, though the association was not statistically significant.

CONCLUSION

The study highlights that gastrostomy site infection is the most common short-term complication following PEG insertion. Immune status and the reason for PEG insertion emerged as key factors influencing the likelihood of complications.

In-hospital, 30- and 90-day mortality in elderly trauma patients with operative feeding tubes

BACKGROUND

Nutrition is essential in the treatment of elderly trauma patients (ETP). ETP experience dysphagia at rates six times higher than the non-trauma elderly population (NTEP) and are at increased risk for malnutrition. Operative feeding tube (OFT) placement is often used to aid with the nutritional management of ETP. Elderly patients experience higher rates of morbidity and mortality when compared to the general population, especially in the traumatic setting, with some data suggesting in-hospital mortality as high as 10%. However, the mortality rates and associated comorbidities associated with OFT in ETP are unknown. The purposes of this study were to establish the mortality rate in hospital as well as 30- and 90-days following discharge among elderly trauma patients (ETP) receiving OFT, and to assess factors associated with mortality within this population.

METHODS

A retrospective review of all trauma patients from a single Level I Trauma Center from 01/2010-09/2020 was conducted. Exclusion criteria were patients under 65 years of age or those with previously placed OFT. Demographics, comorbidities, injury mechanisms, injury severity scores (ISS), and OFT data were collected from the institutional trauma registry. Mortality data were obtained using the Social Security Death Index. Mortality at discharge, 30 days, and 90 days following discharge were the primary outcomes. Bivariate analysis was conducted to compare characteristics and comorbidities of patients alive and dead at the time points of interest.

RESULTS

There were 151 ETP who received OFT. Patients were largely male (67.5%), severely injured via a blunt mechanism (95%), and had a median age of 76 years. 11 (7.3%) experienced in-hospital mortality following feeding tube placement, 21 (13.9%) died within 30 days, and 31 (20.5%) within 90 days. Bivariate analysis demonstrated that ETP who died were more likely to have a history of dementia (p = 0.004), congestive heart failure (p = 0.014), and end-stage liver disease (p = 0.034). No other patient or injury factors were associated with mortality after OFT placement.

CONCLUSION

Mortality rates for ETP with OFT were higher than anticipated, yet favorable compared to recently reported data. Patients who died were more likely to have dementia, CHF, or ESLD than those who survived. The few comorbidities associated with mortality suggest that nearly all ETP who undergo OFT placement are at risk for mortality. Additionally, the data highlights the importance of early goals of care discussions for ETP and their loved ones when operative feeding tubes are being considered.

Evaluation of 644 Percutaneous Endoscopic Gastrostomy Patients in a Single Center

OBJECTIVE

Our study aimed to review and evaluate the indications, complications, complication-related risk factors, and mortality rates of percutaneous endoscopic gastrostomy (PEG) performed in a single university hospital.

METHODS

We retrospectively examined hospital records of all 819 patients who underwent PEG between January 2010 and January 2019. Patients whose information was not available for various reasons, who had a history of gastrectomy, who were under 18 years old, and/or who had undergone PEG before, were excluded from the study.

RESULTS

The mean age of the patients was 65.12 ± 15.42 years, and the majority of the patients (60.6%) were female. In the vast majority of patients, the PEG indication was due to neurological causes (71.5%), among which the majority was a stroke. The overall complication rate in our study was 11.2%. The most common was a peristomal infection in 37 (5.7%) patients. Patients who were not under any antibiotic treatment and/or had diabetes mellitus had a higher risk for peristomal infection. Dementia increased the risk of tube dislodgement. The use of clopidogrel, the simultaneous use of aspirin and clopidogrel, and hypertension were independent risk factors for bleeding complications. The one-year mortality risk was significantly higher in patients who underwent PEG due to neurological causes compared to those who underwent PEG due to malignancy or other reasons (p = 0.021, p = 0.038, respectively).

CONCLUSION

The PEG procedure is a safe and feasible technique due to its low complication and mortality rate in patients with swallowing disorders who need long-term nutritional support.

Factors Associated with 30-Day Mortality in Patients after Percutaneous Endoscopic Gastrostomy

Introduction:

Percutaneous endoscopic gastrostomy (PEG) is the main accepted method for long-term tube feeding. The aim of this study is to investigate the risk factors associated with early mortality after PEG.

Methods:

It is a retrospective survival analysis in a tertiary-level hospital. We reviewed the medical records of 277 patients with PEG placement. The data were analyzed by the Kaplan-Meier method. Multivariable Cox proportional regression models were also built to test the effects of PEG on mortality.

Results:

A total of 277 patients who submitted to PEG were studied. One-hundred and sixty (58%) were female, mean age of 73.3 ± 15.7 years. Ninety-three patients (33.6%) had diabetes mellitus and 165 (59.6%) had blood hypertension. The indications for PEG placement were chronic neurologic dysphagia in 247 (89.5%) patients and tumors and other diseases in 29 (10.5%). The 30 days proportional mortality probability rate was 13%. In a multivariate Cox proportional regression model, preoperative ICU hospitalization (HR 1.79, 95% CI 1.36–2.36, P = 0.000) and hemoglobin (HR 0.91, 95% CI 0.85–0.98, P = 0.015) were predictors of early mortality.

Conclusion:

In patients who had underwent PEG tube insertion for long-term nutrition, anemia and previous ICU admission were predictors of mortality at four weeks. These factors may guide physicians to discourage the indication for PEG.

Comparison of Clinical Outcomes Between Surgical Gastrostomy and Percutaneous Endoscopic Gastrostomy with Introducer Technique in Patients with Upper Aerodigestive Malignancies: A Single-Center Analysis

BACKGROUND

Conventional percutaneous endoscopic gastrostomy (PEG) in patients with upper aerodigestive malignancies inevitably carries a risk of stomal metastasis that could be avoided by the direct insertion of the gastrostomy tube through the abdomen. This study compared the efficacy and safety between surgical gastrostomy (SG) and Introducer PEG in patients with upper aerodigestive malignancies.

METHODS

We retrospectively reviewed patients with upper aerodigestive malignancies undergoing SG or Introducer PEG. Procedure data, postprocedural clinical outcomes and 30-day mortality were assessed.

RESULTS

In total, 99 patients were feasible to analysis: 53 were in the SG group, and 46 were in the Introducer PEG group. The SG group had a higher incidence of (in-hospital) major complications [28.3% VS 4.3%, p = 0.002], a longer procedure duration [52.02 ± 21.30 VS 21.46 ± 8.22 min, p < 0.001], higher pain scores at 24 h [median (interquartile range, IQR); 5(3-8) VS 1(0-5), p < 0.001] and longer length of hospitalization (LOH) [median (IQR); 5(4-6) days VS 3(2-4) days, p < 0.001)]. In-hospital (3.8% VS 0%, p = 0.493) and 30-day mortality (17.0% VS 13.0%, p = 0.586) were not different between the two groups. In univariate analysis, high BMI, anemia (hemoglobin <11 g/dL), normal nutritional status (serum albumin >3 g/dL) and procedural type were found to be predicting factors for complications. Procedural type (Introducer PEG) was an independent factor for major complications in multivariate analysis [OR = 0.12, 95% CI 0.02-0.61, p= 0.011].

CONCLUSIONS

In patients with upper aerodigestive malignancies, Introducer PEG was associated with lower rate of (in-hospital) major complications, faster operative time, lower pain scores and shorter LOH.

Survival Analysis of Enterally Fed Patients: Prognosis and Mortality Risk According to Baseline Characteristics

BACKGROUND

Enteral nutrition is widely used. However, its benefits remain unclear in specific conditions like dementia. This study assesses the survival of enterally fed patients and the baseline characteristics associated with higher mortality.

METHODS

A retrospective analysis of biochemical and clinical data from 377 patients (age 77.5 ± 13.8) who received enteral tube feeding (ETF) at a tertiary hospital in Spain was performed. Kaplan-Meier and Cox regressions were used to analyze survival expectancy and mortality risk (MR). Risk was evaluated for 30/180 days and up to 5 years.

RESULTS

The most common individual diagnoses leading to ETF prescription were dementia (37.9%) and head/neck/upper-gastrointestinal-tract cancer (17.5%). Comorbidities (high blood pressure [HBP] and/or diabetes) were present in 72.4% of patients. The first 30 days after tube placement showed the highest mortality rate, corresponding to 85.4% of patients that did not continue being tube-fed. Multivariate Cox analysis (P < .05, 95% CI) showed HBP and glycemia to be predictive of overall (hazard ratio [HR] = 1.600; HR = 1.756) and long-term (HR = 3.092; HR = 4.539) death. In the short-term, only glycemia showed an increased MR (HR = 1.572).

CONCLUSION

This enterally fed population showed a noticeably high initial mortality rate. Despite official recommendations against it, ETF is very common in advanced dementia. Baseline characteristics are useful for identifying patients that would be less benefited by the intervention. Accordingly, families should be informed about realistic outcomes and risks derived from this procedure.
