Predictors of Percutaneous Endoscopic Gastrostomy Tube Placement after Stroke

Outcomes of stroke patients undergoing percutaneous endoscopic gastrostomy: a systematic review and meta-analysis

BACKGROUND

Percutaneous endoscopic gastrostomy (P.E.G.) is recommended for stroke patients with dysphagia to sustain oral nutrition.

OBJECTIVE

This study assesses the outcomes of stroke patients undergoing P.E.G. compared with those requiring nasogastric tube (N.G.T) or control group.

METHODS

We performed a thorough search across five electronic databases to gather pertinent studies. Outcomes were analyzed using relative risk (R.R.) for categorical data and mean difference (M.D.) for continuous data, each with 95% confidence intervals (C.I.). The single-arm meta-analysis results were presented as proportions or mean changes, also with 95% C.I.

RESULTS

We included 22 studies consisting of 996,567 patients. Our double-arm meta-analysis (924,134 patients) revealed no significant difference in post-hospitalization or in-hospital mortality between P.E.G. and control groups. However, P.E.G. patients showed a higher risk of aspiration pneumonia than control (R.R. = 11.72[3.75, 36.62], p < 0.00001). A comparison of P.E.G. and N.G.T. in three studies involving 691 patients indicated a non-significant difference in-hospital mortality risk (R.R. = 0.59, 95% C.I. [0.2, 1.72]). The single-arm analysis of stroke patients with P.E.G. identified a 19.8% in-hospital mortality, 13.6% rate of aspiration pneumonia, and 58% rate of pneumonia.

CONCLUSION

Stroke patients undergoing P.E.G remain at high risk for aspiration pneumonia and with an in-hospital mortality suggesting the need for identifying the best candidates and timing for the procedure.

Factors Contributing to Complete Oral Intake in Dysphagic Stroke Patients with Enteral Feeding Tubes in Convalescent Rehabilitation Wards

Objectives:

This study investigated the factors contributing to complete oral intake (COI) in dysphagic stroke patients with enteral feeding tubes in the local clinical setting.

Methods:

Data of patients with percutaneous endoscopic gastrostomy (PEG) or nasogastric tube (NGT) feeding on admission to convalescent rehabilitation wards (CRWs) were extracted from the Kaga Regional Cooperation Clinical Pathway for Stroke database for multiple centers including 19 acute care hospitals and 11 hospitals with CRWs. Patients were divided into two groups based on their status regarding COI or incomplete oral intake (ICOI) at discharge. Logistic regression analysis with forced-entry variables was used to identify factors contributing to COI.

Results:

On discharge from CRWs, COI and ICOI were observed in 140 and 207 cases, respectively. The COI group was younger, had a higher rate of initial stroke, higher Functional Oral Intake Scale (FOIS) scores, higher Functional Independence Measure (FIM) motor and cognitive scores, higher Body Mass Index (BMI), lower rate of patients with PEG, and shorter stays in acute care wards. Logistic regression analysis with forced entry revealed that younger age; initial stroke; higher FOIS score, FIM cognitive score, and BMI; and shorter stay in the acute care ward contributed to COI.

Conclusions:

The primary factors contributing to COI in dysphagic stroke patients with enteral feeding tubes were younger age, initial stroke, higher swallowing and cognitive function, good nutritional status, and shorter stay in the acute care ward.

Predictive Factors for Oral Intake Recovery After Acute Stroke: Analysis of a Japanese Nationwide Inpatient Database

OBJECTIVE

It remains unclear which factors contribute to dysphagia recovery after an acute stroke. This study aimed to identify factors associated with complete oral intake recovery in patients with post-stroke dysphagia.

METHODS

Data were obtained from the Diagnosis Procedure Combination database, which is a nationwide database of administrative claims and discharge abstracts in Japan. We selected patients admitted within 3 days of stroke onset and conducted multivariable logistic regression analysis. Total oral intake within 30 days of admission was the primary outcome measure.

RESULTS

A total of 151,302 patients were included, and total oral intake was observed in 48% of them within 30 days of admission. Total oral intake was significantly associated with age, sex, stroke subtype, consciousness disturbance, low body mass index, multiple comorbidities, and the modified Rankin Scale before stroke onset. In addition, males had worse outcomes than females (odds ratio, 0.75; 95% confidence interval, 0.73-0.77, p < 0.001), and intracerebral and subarachnoid hemorrhagic stroke subtypes were associated with non-recovery.

CONCLUSION

This study identified several prognostic factors for total oral intake in patients with acute stroke. These results may be useful for predicting a patient's dysphagia prognosis at the time of admission and designing a nutritional management plan for patients with acute stroke.

Predictive Model of Dysphagia and Brain Lesion-Symptom Mapping in Acute Ischemic Stroke

Background and purpose: Early recognition and management of post-stroke dysphagia (PSD) based on MRI may reduce the incidence of complications. Combining clinical symptoms with applications of MRI, we aimed to identify the risk factors of PSD, develop a prediction scale with high accuracy and map key dysphagia brain areas.

Methods: A total of 275 acute ischemic stroke patients were enrolled in this study, and 113 (41.1%) patients were diagnosed with PSD. All patients underwent the water-swallowing test (WST) and volume-viscosity swallow test (V-VST) within first 24 h following admission to assess swallowing. Vascular factors were evaluated and MRI brain scans were obtained within 3 days after symptom onset for each participant admitted to the hospital. T-test, chi-squared test and Fisher’s exact test were used to investigate the associations of various patient characteristics with dysphagia, and multivariable logistic regression models were used to construct a prediction scale. Scale accuracy was assessed using receiver operating characteristic (ROC) analysis. We extracted white matter hyperintensities for each patient as potential brain lesions. Voxel-based lesion-symptom mapping (VLSM) was used to identify key brain areas for dysphagia.

Results: Risk factors related with PSD were older age, history of atrial fibrillation, higher fasting blood glucose, NIH stroke scale, TOAST classification, progressive stroke, middle cerebral artery lesion and anterior cerebral artery lesion. Three variables with most significant associations, including NIH stroke scale, TOAST classification and progressive stroke, combined with age and gender, were used to construct a dysphagia prediction scale with high accuracy (AUC = 0.86). VLSM identified left inferior parietal gyrus as a key brain region for PSD.

Conclusion: Risk factors of PSD were identified and a predictive model of dysphagia was constructed intelligently and automatically. The left inferior parietal gyrus was identified as a key brain area for dysphagia, which provides a new symptom-based treatment target for early rehabilitation in the future.

Unsedated Outpatient Percutaneous Endoscopic Gastrostomy in Stroke Patients: Is It Feasible and Safe?

Percutaneous endoscopic gastrostomy (PEG) is an established practice for long-term nutrition in dysphagia-suffering stroke patients. This study sought to determine the feasibility and safety of outpatient, unsedated PEG implementation in stroke patients. This retrospective cohort study involved stroke victims who underwent unsedated outpatient PEG insertion from 2014 to 2017 at our Surgical Endoscopy Unit. Patients were given pharyngeal anesthesia with lidocaine 10% spray, while the PEG tube was placed under local anesthesia. The incidence of intraprocedural and postprocedural complications and 30-day mortality rate were recorded. Data from 127 cases were analyzed. The procedures were performed with minor, transient complications, which resolved after rescue maneuvers. No intraprocedural and postprocedural major complications or death were observed. During the 30-day follow-up, the most important complication involved a single case of accidental PEG removal that was successfully resolved surgically. Unsedated PEG insertion appears to be a feasible, well-tolerated, and safe option for stroke-related dysphagia.

Outcomes of Tracheostomy With Concomitant and Delayed Percutaneous Endoscopic Gastrostomy in the Neuroscience Critical Care Unit

BACKGROUND

In patients with severe neurologic conditions, percutaneous endoscopic gastrostomy (PEG) is typically performed either alone or with a tracheostomy. The characteristics and outcomes of patients receiving PEG concomitantly with a tracheostomy (CTPEG) and those receiving delayed PEG (DPEG) after a tracheostomy were compared.

METHODS

Retrospective cohort study in a 24-bed neuroscience critical care unit (NCCU) at a tertiary care hospital. Consecutive patients admitted to the NCCU from April 2007 to July 2013 who underwent percutaneous tracheostomy and gastrostomy by the percutaneous tracheostomy team were included and grouped according to the timing of PEG placement: CTPEG versus DPEG.

RESULTS

Of the 290 patients, 234 (81%) received CTPEG. Demographic and clinical characteristics were similar among the 2 groups except for a lower median (interquartile range [IQR]) body mass index (BMI; 27 [22.67-31.60] versus 30.8 [24.55-40.06], P = .017) and lower rate of acute respiratory distress syndrome (3.85% vs 10.71%, P = .048) in the CTPEG cohort. Furthermore, 59% of CTPEG cohort were neurology patients while 63% of DPEG were neurosurgery patients, P = .004. Primary outcomes showed shorter mean NCCU length of stay (LOS; 25 [12] vs 33 [17] days, P < .001) and median hospital LOS (32 [25-43] vs 37 [31-56] days, P = .002) for the CTPEG cohort. Secondary outcomes showed higher predischarge prealbumin levels (15.6 [7.75] vs 11.58 [5.41], P = .021) and lower median overall hospital cost (US$123 860.20 [US$99 024-US$168 713.40] vs US$159 633.50 [US$121 312-US$240 213.10], P = .0003) in the CTPEG group. Anatomic contraindications were the most common reason for DPEG (30%).

CONCLUSIONS

Among institutions with a tracheostomy team, the practice of tracheostomy with concomitant PEG placement may be considered as feasible as delayed PEG in carefully selected neurocritically ill patients with possible advantages of overall shorter NCCU and hospital LOS, higher predischarge prealbumin, and lower hospital costs. These findings may aid in decisions regarding the timing of PEG placement in the NCCU. Further prospective studies are warranted.

Factors Predicting Recovery of Oral Intake in Stroke Survivors with Dysphagia in a Convalescent Rehabilitation Ward

BACKGROUND

Percutaneous endoscopic gastrostomy may be performed in dysphagic stroke patients. However, some patients regain complete oral intake without gastrostomy. This study aimed to investigate the predictive factors of intake, thereby determining gastrostomy indications.

METHOD

Stroke survivors admitted to our convalescent rehabilitation ward who underwent gastrostomy or nasogastric tube placement from 2009 to 2015 were divided into 2 groups based on intake status at discharge. Demographic data and Functional Independence Measure (FIM), Dysphagia Severity Scale (DSS), National Institutes of Health Stroke Scale, and Glasgow Coma Scale (GCS) scores on admission were compared between groups. We evaluated the factors predicting intake using a stepwise logistic regression analysis.

RESULTS

Thirty-four patients recovered intake, whereas 38 achieved incomplete intake. Mean age was lower, mean body mass index (BMI) was higher, and mean time from stroke onset to admission was shorter in the complete intake group. The complete intake group had less impairment in terms of GCS, FIM, and DSS scores. In the stepwise logistic regression analysis, BMI, FIM-cognitive score, and DSS score were significant independent factors predicting intake. The formula of BMI × .26 + FIM cognitive score × .19 + DSS score × 1.60 predicted recovery of complete intake with a sensitivity of 88.2% and a specificity of 84.2%.

CONCLUSIONS

Stroke survivors with dysphagia with a high BMI and FIM-cognitive and DSS scores tended to recover oral intake.

Mortality trend and predictors of mortality in dysphagic stroke patients postpercutaneous endoscopic gastrostomy

Background:

Percutaneous endoscopic gastrostomy (PEG) feeding is widely used in stroke patients suffering from persistent dysphagia; however, predicting the risks and benefits of PEG insertion in the individual patient is difficult. The aim of our study was to investigate if candidate risk factors could predict short-term mortality risk in poststroke patients who had PEG tube insertion for persistent dysphagia.

Methods:

This was a retrospective study of 3504 consecutive stroke patients admitted to two metropolitan hospitals during the period January 2005 to December 2013 and who also underwent PEG insertion for feeding due to persistent dysphagia.

Results:

A total of 102 patients were included in the study. There were 22 deaths in 6 months after insertion of PEG tubes and 20 deaths of those occurred within 3 months post PEG. Those who survived beyond 6 months showed significantly lower mean age (75.9 ± 9.0 years vs. 83.0 ± 4.9 years, P < 0.001), a lower mean American Society of Anesthesia (ASA) score (3.04 ± 0.63 vs. 3.64 ± 0.58, P < 0.001) compared to nonsurvivors. In multiple Logistic, age (P = 0.004, odds ratio [OR] = 1.144; 95% confidence interval [CI]: 1.044–1.255); ASA (P = 0.002, OR = 5.065; 95% CI: 1.815–14.133) and albumin level pre-PEG insertion (P = 0.033, OR = 0.869; 95% CI: 0.764–0.988) were the independent determinants of mortality respectively.

Conclusions:

We propose that age, ASA score and albumin level pre-PEG insertion to be included as factors to assist in the selection of patients who are likely to survive more than 3 months post PEG insertion.
