Clinical experience of percutaneous endoscopic gastrostomy in Taiwanese patients--310 cases in 8 years

Time trends and outcomes of gastrostomy placement in a Swedish national cohort over two decades

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) and laparoscopically inserted gastrostomy have become the gold standard for adult patients and children, respectively, requiring long-term enteral nutrition support. Procedure-related mortality is a rare event, often reported to be zero in smaller studies. National data on 30-d mortality and long-term survival rates after gastrostomy placement are scarce in the literature.

AIM

To study the use of gastrostomies in Sweden from 1998-2019 and to analyze procedure-related mortality and short-term (< 30 d) and long-term survival.

METHODS

In this retrospective, population-based cohort study, individuals that had received a gastrostomy between 1998-2019 in Sweden were included. Individuals were identified in the Swedish National Patient Register, and survival analysis was possible by cross-referencing the Swedish Death Register. The cohort was divided into three age groups: Children (0-18 years); adults (19-64 years); and elderly (≥ 65 years). Kaplan-Meier with log-rank test and Cox regression were used for survival analysis.

RESULTS

In total 48682 individuals (52% males, average age 60.9 ± 25.3 years) were identified. The cohort consisted of 12.0% children, 29.5% adults, and 58.5% elderly. An increased use of gastrostomies was observed during the study period, from 13.7/100000 to 22.3/100000 individuals (P < 0.001). The use of PEG more than doubled (about 800 to 1800/year), with a corresponding decrease in open gastrostomy (about 700 to 340/year). Laparoscopic gastrostomy increased more than ten-fold (about 20 to 240/year). Overall, PEG, open gastrostomy, and laparoscopic gastrostomy constituted 70.0% (n = 34060), 23.3% (n = 11336), and 4.9% (n = 2404), respectively. Procedure-related mortality was 0.1% (n = 44) overall (PEG: 0.05%, open: 0.24%, laparoscopic: 0.04%). The overall 30-d mortality rate was 10.0% (PEG: 9.8%, open: 12.4%, laparoscopic: 1.7%) and decreased from 11.6% in 1998-2009 vs 8.5% in 2010-2019 (P < 0.001). One-year and ten-year survival rates for children, adults, and elderly were 93.7%, 67.5%, and 42.1% and 79.9%, 39.2%, and 6.8%, respectively. The most common causes of death were malignancies and cardiovascular and respiratory diseases.

CONCLUSION

The annual use of gastrostomies in Sweden increased during the study period, with a shift towards more minimally invasive procedures. Although procedure-related death was rare, the overall 30-d mortality rate was high (10%). To overcome this, we believe that patient selection should be improved.

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.

Mortality and complications after percutaneous endoscopic gastrostomy: a retrospective multicentre study

Background

Percutaneous endoscopic gastrostomy (PEG) is the method of choice for patients in need of long-term nutritional support or gastric decompression. Although it is considered safe, complications and relatively high mortality rates have been reported. We aimed to identify risk factors for complications and mortality after PEG in routine healthcare.

Methods

This retrospective study included all adult patients who received a PEG between 2013 and 2019 in Region Norrbotten, Sweden.

Results

389 patients were included. The median age was 72 years, 176 (45%) were women and 281 (72%) patients received their PEG due to neurological disease. All-cause mortality was 15% at 30 days and 28% at 90 days. Malignancy as the indication for PEG was associated with increased mortality at 90 days (OR 4.41, 95% CI 2.20–8.88). Other factors significantly associated with increased mortality were older age, female sex, diabetes mellitus, heart failure, lower body mass index and higher C-reactive protein levels. Minor and major complications within 30 days occurred in 11% and 15% of the patients, respectively. Diabetes increased the risk of minor complications (OR 2.61, 95% CI 1.04–6.55), while those aged 75 + years were at an increased risk of major complications, compared to those younger than 65 years (OR 2.23, 95% CI 1.02–4.85).

Conclusions

The increased risk of death among women and patients with malignancy indicate that these patients could benefit from earlier referral for PEG. Additionally, we found that age, diabetes, heart failure, C-reactive protein and body mass index all impact the risk of adverse outcomes.

Factors affecting late complications of percutaneous endoscopic gastrostomy tube replacement

BACKGROUND

Late complications associated with percutaneous endoscopic gastrostomy (PEG) tube in patients are common occurrences. We aimed to identify risk factors associated with PEG-related late complications.

METHODS

Patients who underwent PEG exchange were retrospectively collected from electronic medical records between January 2015 and November 2020. Medical records were reviewed longitudinally from the PEG replacement date until the first complication event, death, or the end of the study. The late complication was defined as the PEG-related complications six months after the initial PEG placement. Potential risk factors were tested using Cox proportional hazard.

RESULTS

A total of 116 patients (mean age 80.5 ± 17.6 years, 52.6% male) were enrolled with a 12 (4-23) months median follow-up. The indications were mostly neurologic disease (89.7%). Non-balloon PEG was used in 93 (80.2%) patients with balloon-type in 23 (19.8%) patients. PEG-related late complications developed in 35 (30.2%) patients with a median time of 9 (4-23) months. In the multivariate analysis, the PEG-related late complication rate was significantly higher in patients with balloon-type PEG tube (HR 5.54; 95%CI, 2.55-12.05; p < 0.001) and also showed a significantly higher cumulative incidence of developing complications (54.9% vs. 12.8% at one year and 76% vs. 22.8% at two years, p < 0.001). The most common complication was PEG dislodgement (n = 14, 40%).

CONCLUSION

Late-onset of PEG tube-associated complications is a common problem. The significant factor associated with PEG tube complication was balloon-type PEG placement.

Prognostic nutritional index and early mortality with percutaneous endoscopic gastrostomy

BACKGROUND

Although percutaneous endoscopic gastrostomy (PEG) is a well-accepted and less invasive method of feeding tube placement in patients with swallowing difficulties, complications and early death after PEG have been reported.

AIM

This study aimed to evaluate predictive factors associated with 30-day mortality after PEG, and to assess the utility of nutritional supporting period before PEG in reducing early mortality following PEG.

DESIGN

An observational study.

METHODS

We retrospectively analyzed 268 patients who underwent PEG at Sapporo Shirakaba-dai Hospital from 2006 to 2010, using clinical and laboratory data to analyze predictive factors associated with early death after PEG. Then, we prospectively assessed 152 consecutive patients assessed for eligibility for PEG from 2011 to 2014. We assessed the patients' nutritional condition using Onodera's prognostic nutritional index (PNI), and supported nutrition for more than 10 days before PEG in patients with a poor nutritional index (PNI < 37).

RESULTS

In both univariate and multivariate analyses in the retrospective study, Onodera's PNI of less than 37 was the only predictive factor for early mortality. In the second study, among the 115 patients who finally underwent PEG, early mortality rates improved to 1.7% from 5.2% in the first study. Conversely, 32% of patients with malnutrition who did not undergo PEG died within 30 days.

CONCLUSION

Nutritional status might be a predictive factor for early mortality after PEG. In patients with poor nutritional status, nutritional supporting period before PEG might improve the outcomes and reduce unnecessary PEG.

Risk factors for complications and mortality of percutaneous endoscopic gastrostomy insertion

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) is a relatively safe procedure; however, acute and chronic complications of PEG have been reported. We aimed to determine risk factors associated with complications and 30-day mortality after PEG, based on 11 years of experience at a single tertiary hospital.

METHODS

In total, 401 patients who underwent first PEG insertion at the Asan Medical Center, Seoul, Korea, between January 2005 and December 2015 were eligible. Medical records were retrospectively reviewed to determine clinical characteristics and outcomes of 139 and 262 patients who underwent pull-type and introducer-type PEG, respectively.

RESULTS

The median age of the overall population was 68 years, and the median body mass index was 19.5 kg/m2. Acute and chronic complications developed in 96 (23.9%) and 105 (26.2%) patients. Acute ileus and chronic tube obstruction were significantly more frequent in the introducer-type PEG group (p = 0.033 and 0.001, respectively). The 30-day mortality rate was 5.0% (median survival: 10.5 days). Multivariate analysis revealed that underlying malignancy was a predictor of acute complications; age ≥ 70 years and diabetes mellitus were predictors of chronic complications. The median follow-up was 354 days. Neurologic disease and malignancy were the most common indications for PEG. Neurologic diseases were classified into two groups: stroke and the other neurologic disease group (including dementia, Parkinson's disease, neuromuscular disease, and hypoxic brain damage). Multivariate analysis showed that 30-day mortality was significantly lower in the other neurologic disease group and higher in patients with platelet count < 100,000/μL, and C-reactive protein (CRP) ≥ 5 mg/dL.

CONCLUSIONS

PEG is a relatively safe and feasible procedure, but it was associated with significantly higher early mortality rate in patients with platelet count < 100,000/μL or CPR≥5mg/dL, and lower early mortality rate in neurologic disease group including dementia, Parkinson's disase, neuromuscular disease, and hypoxic brain damage. In addition, acute complications in patients with underlying malignancy, and chronic complications in patients aged ≥70 and those with diabetes mellitus should be considered during and after PEG.

Trends regarding percutaneous endoscopic gastrostomy: A nationwide population-based study from 1997 to 2010

Percutaneous endoscopic gastrostomy (PEG) is widely used in patients requiring long-term tube feeding. Traditional PEG studies usually focused on practical, technical, and ethical issues. There have been little epidemiological studies on PEG utilization and services in Asia. We evaluated the changes in PEG utilization, patient selection, patient characteristics, and medical service in Taiwan from 1997 to 2010.This retrospective study analyzed the data of patients admitted for PEG tube placement according to the International Classification of Diseases, Ninth Revision (procedure code 43.11) extracted from the National Health Insurance database between 1997 and 2010.From 1997 to 2010, the incidence of PEG increased from 0.1 to 3.8/10 population and incidence of PEG among aged patients increased from 0.9 to 19.0/10 population. Compared 1997-2004 to 2005-2010 periods, the percentage of cerebrovascular diseases decreased and esophageal cancer increased in the later period. PEG was mainly performed in male patients and at medical centers. Medical costs, Charlson Comorbidity Index (CCI) scores, and post-PEG mortality rates were higher in the 2005-2010 period than in the 1997-2004 period.PEG procedures are being increasingly performed in Taiwan, and changes in patient selection were noted. The seriousness of accompanying diseases, medical costs, and post-PEG mortality rates in patients undergoing PEG has increased. The present findings may help in the implementation of PEG, relocation of medical resources, and improvement of PEG-related care.

Risk factors for complications and mortality of percutaneous endoscopic gastrostomy: a multicenter, retrospective study

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) is performed to provide nutrition to patients with swallowing difficulties. A multicenter study was conducted to evaluate the predictors of complications and mortality after PEG placement.

METHODS

This study retrospectively analyzed patients who underwent initial PEG placement between January 2004 and December 2011 at seven tertiary hospitals in the Republic of Korea.

RESULTS

All 1,625 patients underwent PEG placement by the pull-string method. The median age of the patients was 66 years, and 1,108 of the patients were men. The median follow-up period was 254 days. The common indications were stroke (31.6%) and malignancy (18.9%). The complication rate was 13.2%. The prophylactic use of antibiotics (odds ratio [OR], 0.58; 95% confidence interval [CI], 0.38-0.88; p = 0.010) reduced the PEG-related infection rate, but the actual usage rate was 81.1%. The use of anticoagulants (OR, 7.26; 95% CI, 2.23-23.68; p = 0.001) and the presence of diabetes mellitus (OR, 4.02; 95% CI, 1.49-10.87; p = 0.006) increased the risk of bleeding, but antiplatelet therapy did not. The procedural, 30-day, and overall mortality rates were 0.2, 2.4 and 14.0%, respectively. Serum albumin levels lower than 31.5 g/L (OR, 8.55; 95% CI, 3.11-23.45; p < 0.001) and C-reactive protein levels higher than 21.5 mg/L (OR, 3.01; 95% CI, 1.27-7.16; p = 0.012) increased the risk of 30-day mortality, and the patients who had both risk factors had a significantly shorter median survival time than those who did not (1,740 vs 3,181 days) (p < 0.001, log-rank).

CONCLUSIONS

The findings showed PEG to be a safe and feasible procedure, but the patient's nutritional and inflammatory status should be considered in predicting the outcomes of PEG placement.

Effect of the introducer technique compared with the pull technique on the peristomal infection rate in PEG: a meta-analysis

BACKGROUND

Peristomal infection is a main complication of PEG. The pull technique appears to be associated with higher infection rates compared with the introducer technique, although published results are controversial.

OBJECTIVE

To determine which technique is associated with a higher risk of infection.

DESIGN

Systematic review and meta-analysis.

SETTING

Studies reporting rates of peristomal infection after PEG performed by either the pull or introducer technique.

PATIENTS

This study involved 2336 patients from 6 comparative and 10 observational studies.

INTERVENTION

Public MEDLINE (National Library of Medicine journal articles database), Excerpta Medica Database, Cochrane Central Register of Controlled Trials, and Latin American and Caribbean Center on Health Sciences Information databases and proceedings of two meetings, Digestive Disease Week and United European Gastroenterology Week, were searched. Both comparative and observational studies were included and analyzed separately.

MAIN OUTCOME MEASUREMENTS

Effect measures from each comparative study were reported as the odds ratio (OR). The pooled effect was then calculated. The infection rate in each observational study was also calculated, and a summary effect was then determined.

RESULTS

In comparative studies, the risk of infection was significantly higher with the pull technique (OR 13.0; 95% confidence interval [CI], 4.6-36.8; P < .0001). Similarly, observational studies also reported higher infection rates with the pull technique (10.7%; 95% CI, 4.9-21.8 with the pull technique vs 0.9%; 95% CI, 0.2-4.5 with the introducer technique).

LIMITATIONS

Few studies were available for inclusion, and there was a high risk of bias among the comparative studies.

CONCLUSION

The pull technique appears to be associated with a significantly higher risk of infection compared with the introducer technique.

Peritonitis after gastrostomy tube replacement: a case series and review of literature

BACKGROUND

The placement of feeding gastrostomy (G) tubes through a percutaneous endoscopic gastrostomy (PEG) technique has become common because of its simplicity and safety. The majority of the serious complications are reported to occur within a few days of initial tube placement and happen in fewer than 3% of cases. Long-term reported complications of this procedure include occlusion or breakage of the G-tube, requiring reinsertion. This report describes the complication of intraperitoneal placement and the development of peritonitis after replacement of an established PEG tube and reviews the pertinent world literature.

METHODS

A retrospective review of cases of intraperitoneal insertion of replacement G-tubes was done as well as a Medline search for cases of intraperitoneal insertion of replacement G-tube or development of peritonitis after replacement tube insertion.

RESULTS

Three new cases of inadvertent intraperitoneal insertion of a replacement G-tube in adult patients with mature tracts are reported. An additional 5 cases have been previously described in adults. Significant morbidity was associated with this complication, and 4 deaths were related to it. Methods used to determine whether the replacement G-tube was intragastric were not uniform.

CONCLUSIONS

There have been few reports of intraperitoneal insertion of replacement G-tubes in patients with mature (>30 days) stoma sites. The cases presented in this report highlight for the clinician the importance of considering this complication, particularly if there are any difficulties with the reinsertion. Prospective studies are needed to determine the frequency of this complication and the optimal protocol for PEG replacement.

Prediction of survival and complications after percutaneous endoscopic gastrostomy in an individual by using clinical factors with an artificial neural network system

BACKGROUND

The demand for percutaneous endoscopic gastrostomy (PEG) has increased because it is safe and a technically easy method, but it has risks of severe complications including death and a high mortality rate within 30 days. At present, we cannot predict survival or the incidence of complications before tube placement in an individual. Earlier studies have used traditional statistical analysis by assuming a linear relationship between clinical features, but most phenomena in the clinical situation are not linearly related.

AIMS

We predicted the survival and complications before PEG placement in an individual by using artificial neural network (ANN) system, which can assess the nonlinear relationship.

METHODS

We studied 100 patients who underwent PEG at the Kitasato Medical Institute Hospital from 1997 to 2005. Clinical data and laboratory data were used as input data. Complications related to PEG placement and survival dates were historically and prospectively measured. From the clinical data and laboratory data, we examined the prediction of outcome in individual patients using multiple logistic regression analysis and an ANN.

RESULTS

The correct answer rate of survival by multiple logistic regression analysis was 67.9%. In contrast, using the ANN, we correctly predicted the survival date and aspiration pneumonia in 75 and 89% of patients, respectively. There was a nonlinear relationship among input factors and survival and complications.

CONCLUSION

We correctly predicted the outcome and complications of individual patients with PEG with a high correct answer rate. Our data show the potential of an ANN as a powerful tool in daily clinical use to individualize treatment ('tailor-made medicine') for PEG and reduce costs.

Clinical manifestations and management of buried bumper syndrome in patients with percutaneous endoscopic gastrostomy

BACKGROUND

Buried bumper syndrome has been regarded as an uncommon and late complication after percutaneous endoscopic gastrostomy (PEG) tube insertion. A variety of techniques have been reported to treat this problem, but only a few published cases exist.

OBJECTIVE

Our purpose was to present the clinical manifestations and our management of a series of 19 patients with buried bumper syndrome.

DESIGN

Case series study.

SETTING

Referral medical centers.

PATIENTS

Within 5 years, 31 episodes of buried bumper syndrome occurred in 10 men and 9 women. The estimated prevalence was 8.8% (19 in 216 PEG procedures during this period).

INTERVENTION

All the buried tubes were removed smoothly by external traction and replaced with a new pull-type feeding tube by the pull method or a button or balloon replacement tube after dilation of the old tract.

MAIN OUTCOME MEASUREMENTS

Success rate, complication rate.

RESULTS

The duration between occurrence of buried bumper syndrome and PEG placement ranged from 1 to 50 months, with a median of 18 months. All the episodes were treated successfully except for one, in which reinsertion failed and a new PEG tube was inserted 1 week later. No significant complications occurred.

LIMITATION

Small sample size.

CONCLUSIONS

Buried bumper syndrome is not that uncommon and can occur soon after insertion of a PEG tube. The buried tube can be safely removed by external traction and in most cases can then be replaced with a pull-type or balloon replacement tube.
