Percutaneous endoscopic gastrostomy (PEG) as a measure
of enteral tube feeding has gained wide acceptance, and
it is currently the preferred method for providing enteral
nutrition in long‑term settings with the aim to prevent
the most serious complications. Short‑term studies have
demonstrated the advantages of PEG as compared with
the nasogastric tube feeding in patients with dysphagia
due to chronic neurological diseases. PEG insertion is a
quick procedure that is generally well tolerated by patients,
and a relatively low complication rate in the outcome has
been described.[26] Obese individuals with COPD may have
associated obstructive sleep apnea. These patients may
be more difficult to wean and require early use of NIV
post-extubation.
