The role of endoscopically placed feeding or decompression tubes

Abstract

The minimally invasive nature of endoscopically placed gastrostomy tubes makes them a viable consideration in palliative care. Complications related to the procedure appear to correlate with age and underlying comorbidities.However, in many instances, the scientific basis for establishing benefit or harm from tube placement is methodologically inadequate. Decisions must be preceded by a discussion of the value and potential risk of artificial nutrition in a particular setting, respecting the wishes and beliefs of each patient and his or her family. The decision to use PEG placement for any reason should be consistent with legal and ethical principles, reflect patient autonomy over any other consideration (including beneficence), and arise from a clear determination of the goals of care (and whether the PEG placement will truly help meet those goals). Whenever possible, further studies with better design are needed to evaluate whether the use of PEG truly affects quality of life and patient outcome in palliative care. PEG tubes for decompression are placed successfully most of the time. Symptom relief occurs usually within 7 days of the procedure. Overall, the morbidity related to the PEG procedure for decompression is only slightly higher than when the same technique is used for nutritional purposes. The appropriate timing for PEG tube placement for nutritional support and for decompression throughout the course of disease progression may be difficult to determine and yet may be a factor in its overall efficiency. Only minor modifications of the basic technique used for PEG placement for nutritional purposes are required to adapt the technique to a variety of other applications in palliative care.
