Study summary

This prospective observational cohort study aims to compare the safety and clinical outcomes of sedated and unsedated percutaneous endoscopic gastrostomy procedures in elderly patients classified as ASA IV. The primary outcome is the development of cardiopulmonary complications within the first 24 hours after the procedure. Secondary outcomes include technical success, procedure duration, early procedure-related complications, length of hospital stay, intensive care requirement, 30-day mortality, and 30-day readmission.

Read the detailed description

Percutaneous endoscopic gastrostomy is commonly used to provide long-term enteral nutrition in patients who are unable to maintain adequate oral intake. Elderly patients with severe systemic disease and high anesthetic risk may be vulnerable to sedation-related cardiopulmonary adverse events. In some clinical settings, PEG can be performed using topical pharyngeal anesthesia and local anesthesia without systemic sedation.

This study will prospectively include elderly ASA IV patients undergoing PEG placement in routine clinical practice. Patients will be categorized into two cohorts according to the sedation strategy used during the procedure: unsedated PEG and sedated PEG. The sedation strategy will not be assigned by the investigators and will be determined according to routine clinical assessment, patient condition, and anesthesiology evaluation when required.

The study will compare cardiopulmonary complications within 24 hours, technical success, procedure-related complications, and 30-day clinical outcomes between the two cohorts.

Study population

Elderly ASA IV patients aged 65 years

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with indications for percutaneous endoscopic gastrostomy for long-term enteral nutrition.
  • Patients who have provided written from the patient or their legally authorized representative.
  • Those with an Anesthesia Score of ASA 4.

Exclusion criteria

Exclusion Criteria:

  • Need for emergency PEG placement;
  • (INR) greater than 1.5;
  • count less than 50,000/mm³;
  • Severe ascites,
  • Active peritonitis; pregnancy;
  • Refusal to participate in the study.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Groups and cohorts

  • Unsedated PEG

    Elderly ASA IV patients undergoing percutaneous endoscopic gastrostomy with topical pharyngeal anesthesia and local anesthesia, without systemic sedative medication.

  • Sedated PEG

    Elderly ASA IV patients undergoing percutaneous endoscopic gastrostomy under sedation as part of routine clinical practice. Sedative agents may include propofol, midazolam, and/or opioid agents according to clinical and anesthesiology evaluation.

What researchers measure

Primary outcomes

  1. Incidence of cardiopulmonary complications within 24 hours after PEG placement

    Cardiopulmonary complications will be assessed as a composite outcome including the occurrence of at least one of the following events within the first 24 hours after PEG placement: hypoxemia defined as SpO₂ \<90%, hypotension defined as mean arterial pressure \<65 mmHg, bradycardia defined as heart rate \<50 beats/min, aspiration, need for endotracheal intubation, or intensive care unit admission/transfer.

    Time frame: Within 24 hours after PEG placement

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2026; primary completion for Jun 2027, 10 months later.

Of 117 non-industry observational studies under Deglutition Disorders, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 52. This study's planned 10 months is below that.

Counting every sponsor, half of 120 studies reached it within 25 months; a quarter within 11 and three quarters within 49.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 10, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
