Complications of Percutaneous Endoscopic Gastrostomy Tube Insertion in Cancer Patients: A Retrospective Study

Gastrostomy Tube Insertion Complications and Patient Care Outcomes in a Tertiary Care Hospital

Background

Percutaneous endoscopic gastrostomy (PEG) is a widely known procedure where an endoscopist inserts a tube through the stomach to provide enteral nutrition. The existing literature shows inconsistent results regarding complication rates, and very few studies have examined the relationship between patient characteristics and PEG outcomes. Therefore, we aimed to investigate PEG tube insertion outcomes and determine different variables associated with these outcomes.

Methods

This retrospective record review included 207 patients who underwent PEG tube insertion at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, between 2010 and 2021. We obtained variables such as demographics, complications, and length of hospitalization. The Student t-test, chi-square test, and Mann-Whitney test were used in the data analysis.

Results

Of 207 patients, 106 were male (51.2%). The patient's median age was 10 years, and the median length of hospital stay was two days. The PEG-related complication rate was 32.4%, while the 1-year adverse outcome rate was 44.9%. The most common complications were unspecified fever (21.3%) and vomiting (14%). We found a significant relationship between dysphagia and length of hospitalization (P=0.015) and between age and the occurrence of tube leakage (P=0.021). Another significant relationship was found between the number of PEG insertions and gastrostomy-site infection (P=0.046).

Conclusions

This study's results indicate the importance of a thorough review of patients' medical records; some patient characteristics can be valuable predictors of PEG outcomes. Thus, we urge physicians to study each patient to anticipate PEG tube insertion outcomes carefully. Moreover, we recommend that researchers with access to larger patient registries study more variables to reach unified guidelines that ensure the best possible outcomes.

Artificial Nutrition in Patients with Advanced Malignancy

Cancer is a progressive disease that can lead to malnutrition and cachexia. Artificial nutrition is a medical therapy used to combat malnutrition in these patients. In this article, the authors discuss factors affecting the decision to use artificial nutrition, including the patient's mental and physical health, technical factors of the procedures used to deliver artificial nutrition, and the oncologic factors affecting treatment. Through this review, the authors provide guidelines on who is and is not likely to benefit from therapy, available routes of administration, and necessary factors to consider for appropriate decision-making for palliative patients and those with advanced cancers."

Post cricoid tumours; a limiting factor for percutaneous endoscopic gastrostomy insertion in cancer patients: Results from a tertiary care hospital

BACKGROUND AND STUDY AIMS

The aim of this study was to review all episodes of PEG insertion in patients with head and neck cancer (HNC) at a cancer specialist centre.

PATIENTS AND METHODS

Using a structured data extraction form, we abstracted patients' demographic data and clinical information including the primary site of tumour, TNM staging, whether PEG tube was inserted successfully, any complications resulting from PEG tube insertion and duration the tube was in place.

RESULTS

We identified a total of 339 HNC patients who had received at least one attempted PEG tube insertion. The mean age of patients was 49.5 ± 14.5 years and 66% (n: 233/339) were males. 151/ 339 (44.5%) patients had a tumour in the pharynx and nasopharynx, 103/ 339 (30.4%) in oral cavity, 81/ 339 (23.9%) in post-cricoid region and 4 (1.1%) of the patients had a laryngeal carcinoma. Histopathologically, most tumours (75.8%) were squamous cell carcinoma presenting at a T4 (52.6%), N0 (38.3%) and M0 (91.7%) stage. PEG tube was successfully inserted in 303/339 (89.4%) patients. There were 36 PEG failures; 24 (66.6%) in postcricoid and laryngeal tumours, 8 (22.3%) in pharynx/nasopharynx and 4 (11.1%) in oral cavity tumours. Of the 81 patients with post-cricoid tumour, PEG tube was successfully inserted in 57/ 81 (70.3%) of the patients. Age, gender or T stage of the tumour was not found to be statistically significant predictors of PEG failure. The only significant factor was presence of post-cricoid or laryngeal tumours that increased the risk of PEG failure 12 times (95% confidence interval: 3.4 to 42.3).

CONCLUSION

PEG tube should be used as a first line feeding option in patients with all type of head and neck cancers, however, the attending clinicians should have this foresight of higher failure rates in patients with post-cricoid tumour.

Metastasis to gastrostomy sites from upper aerodigestive tract malignancies: a systematic review and meta-analysis

BACKGROUND AND AIMS

Metastasis to the gastrostomy site in patients with upper aerodigestive tract (UADT) malignancies is a rare but devastating adverse event that has been poorly described. Our aim was to determine the overall incidence and clinicopathologic characteristics observed with development of gastrostomy site metastasis in patients with UADT cancers.

METHODS

This was a systematic review and meta-analysis of 6138 studies retrieved from Medline, EMBASE, CINAHL, and the Cochrane Register after being queried for studies including gastrostomy site metastasis in patients with UADT malignancies.

RESULTS

The final analysis included 121 studies. Pooled analysis showed an overall event rate gastrostomy site metastasis of .5% (95% confidence interval [CI], .4%-.7%). Subgroup analysis showed an event rate of .56% (95% CI, .40%-.79%) with the pull technique and .29% (95% CI, .15%-.55%) with the push technique. Clinicopathologic characteristics observed with gastrostomy site metastasis were late-stage disease (T3/T4) (57.8%), positive lymph node status (51.2%), and no evidence of systemic disease (M0) (62.8%) at initial presentation. The average time from gastrostomy placement to diagnosis of metastasis was 7.78 ± 4.9 months, average tumor size on detection was 4.65 cm (standard deviation, 2.02), and average length of survival was 7.26 months (standard deviation, 6.23).

CONCLUSIONS

Gastrostomy site metastasis is a rare but serious adverse event that occurs at an overall rate of .5%, particularly in patients with advanced-stage disease, and is observed with a very poor prognosis. These findings emphasize a need for clinical practice guidelines to include a regular assessment of the PEG site and highlight the importance of detection and management of gastrostomy site metastasis by the multidisciplinary care oncology team.

Capnography monitoring of non-anesthesiologist provided sedation during percutaneous endoscopic gastrostomy placement: A prospective, controlled, randomized trial

BACKGROUND AND AIM

A number of studies were able to show a reduction of hypoxemia episodes during procedural sedation through the use of capnography (CA). The present study investigates the number of episodes of hypoxemia during percutaneous endoscopic gastrostomy (PEG) placement with propofol sedation comparing standard monitoring (SM) versus SM with additional CA surveillance.

METHODS

In this single center randomized controlled trial, 150 patients were prospectively randomized 1:1 in either the SM group or the CA group after stratification for ASA class, PEG method (push or pull method), presence of head and neck tumor, and tracheostomy. CA analysis was performed for all patients but was blinded for the endoscopic team in the SM group.

RESULTS

In the SM group, 57% episodes of hypoxemia (SpO₂  < 90% for > 15 s) and 41% episodes of severe hypoxemia (SpO₂  < 85% for > 15 s) were observed in comparison with 28% and 20% in the CA group, respectively. Odds ratios for hypoxemia and severe hypoxemia were 0.29 (confidence interval 0.15-0.57; P = 0.0005) and 0.35 (confidence interval 0.17-0.73; P = 0.008) in favor of the CA group. On average, CA was able to detect imminent mild and severe hypoxemia 83 and 99 s before standard monitoring. Standard monitoring represented an independent risk factor for hypoxemia and severe hypoxemia.

CONCLUSIONS

Respiratory complications of sedation during PEG placement are frequent events. CA is able to detect imminent hypoxemia at an early time point. This allows an early intervention and consecutively the avoidance of mild and severe hypoxemia. Therefore, CA monitoring can be recommended particularly during PEG insertion procedures.

Gastrostomy tube use in children with cancer

Children with cancer are at risk of malnutrition, which can impair critical childhood processes of growth and development and contribute to poor health outcomes. Enteral nutrition can effectively ameliorate malnutrition or weight loss in children with cancer; however, published nutrition support algorithms contain minimal specific information on gastrostomy tube use, and current literature is limited. Decisions about gastrostomy tube insertion in children with cancer can be challenging. Consideration of gastrostomy tube insertion is only appropriate in children with long-term dependence on enteral nutrition, particularly when nasogastric tube insertion is predicted or proven to be problematic. Specific indications for patient selection are unclear, and referring clinicians may be unaware of important absolute and relative contraindications. Complications are predominantly minor in nature; however, reported rates are high. Morbidity must be weighed carefully against the need and anticipated duration of enteral nutrition support, and further research in this area is needed.

Nutritional parameters associated with hospital admissions in patients being treated for head and neck cancer

PURPOSE

This study analysed nutritional parameters (baseline body mass index (BMI), weight changes and enteral nutrition (EN) use, and their association with hospital admissions during radiotherapy in patients with head and neck cancer (HNC)).

METHODS

A retrospective review of patients diagnosed with HNC and treated with radiotherapy between October 2012 and April 2014 was conducted. Data on each subject's diagnosis, age, sex, chemotherapy, previous surgery, EN use, weight changes, and BMI were examined for their association with hospital admissions during treatment.

RESULTS

Eighty-three patients were included, mean age (±standard deviation) = 61 (± 11 years). Thirty-four percent had self-reported weight loss at diagnosis, and mean BMI was 26.2 ± 5.3 kg/m². Mean weight change during treatment was - 5.1 ± 6.2%. Ten patients used EN, with mean weight stabilisation during EN use (0.3 ± 5.1%). Higher presenting BMI, younger age, and definitive radiotherapy ± chemotherapy predicted greater weight loss (p < 0.05). Critical weight loss ≥ 5% was associated with a higher number of hospital admissions for nutrition reasons (n = 10) (p = 0.011) compared with those without critical weight loss (n = 2). EN use was associated with a higher number of nutrition-related admissions; however, it did not predict length of stay among those admitted.

CONCLUSION

Critical weight loss during radiotherapy was associated with unplanned nutrition-related hospital admissions. Higher BMI was associated with greater weight loss during radiotherapy, whilst EN use assisted in weight preservation. Further research around patient selection for nutritional interventions aimed at preventing critical weight loss and unplanned hospital admissions is needed.

Tumor implantation following percutaneous endoscopic gastrostomy insertion for head and neck and oesophageal cancer: Review of the literature

BACKGROUND

Because of publication bias, there is uncertainty about the true incidence of tumor seeding or implantation in patients with head and neck or oesophageal cancer undergoing percutaneous endoscopic gastrostomy (PEG) insertion.

METHODS

In order to obtain a more reliable estimate of risk, a systematic review was undertaken. Randomized or non-randomized studies and case reports were identified by electronic searching. A risk of bias assessment was carried out for each study.

RESULTS

Ninety-eight cases from 74 published case reports and 1 unpublished case were identified. Synchronous distant metastases were present in 37%. Analysis of case series (6192 patients) considered to carry a moderate risk of bias suggests an incidence of seeding after PEG insertion of 0.32%. Studies carrying a lower risk of bias indicate a risk of seeding closer to 1 in 2000.

CONCLUSION

The true risk of seeding after PEG insertion is probably less than 1 in 1000.

Risk factors for prolonged need for percutaneous endoscopic gastrostomy (PEG) tubes in adult trauma patients: Experience of a level 1 trauma

BACKGROUND

Percutaneous endoscopic gastrostomy tubes are a means of providing an alternative enteric route of nutrition. This study sought to identify risk factors for the prolonged need of a percutaneous endoscopic gastronomy tube (≥90 days) in adult trauma patients.

METHODS

The trauma database of a level 1 trauma center was queried retrospectively to identify patients who had percutaneous endoscopic gastronomy tubes placed.

RESULTS

A total of 9,772 charts were reviewed with 282 patients (2.9%) undergoing successful percutaneous endoscopic gastronomy tube placement. On review of discharged living patients, 195 had adequate clinical documentation to allow for analysis. The mean age was 57.5 years, admission serum albumin was 3.7 g/dL, and Charlson Comorbidity Index score was 1.1. The first recorded mean Glasgow Coma Scale was 10.7, and their Injury Severity Score was 23.2. The mean duration of total hospital stay was 23.8 days, intensive care unit stay was 16.5 days, and in-hospital ventilator days was 11.5. Of the 272 patients, 77 (41.4%) required percutaneous endoscopic gastronomy tubes for >90 days. Statistically significant characteristics on univariate analysis included increasing age, a greater Charlson Comorbidity Index score, and a greater number of in-hospital ventilator days. On logistic regression, a Charlson Comorbidity Index score >1 (odds ratio 1.27, 95% confidence interval 1.03-1.56, P = .02) and greater in-hospital ventilator days (odds ratio 1.05, 95% confidence interval 1.02-1.09, P < .01) were predictive of the need for prolonged percutaneous endoscopic gastronomy tube placement.

CONCLUSION

A Charlson Comorbidity Index score >1 and prolonged in-hospital ventilator days were risk factors for the necessity of a percutaneous endoscopic gastronomy tube for ≥90 days after placement. This observation may assist patients/surrogates in decision-making when needing alternative routes for nutrition.
