[Percutaneous endoscopic gastrostomy in Iceland over 10 year period: a retrospective study of indications, complications and ethical issues]

Abstract

Objective: Percutaneous endoscopic gastrostomy (PEG) is the preferred method for long term enteral feeding. No nationwide study has reported on the experience and outcome of PEG procedure. The aim of this study was to describe the frequency, indications, complications, mortality and ethical issues related to PEG procedures in Iceland.

Material and methods: A retrospective study was performed on all adult patients who had PEG procedures in Iceland between 2000-2009. Medical charts from patients found were reviewed and data regarding demographics, indications, complications, mortality and ethically controversial cases was obtained.

Results: A total of 278 patients had PEG procedures during the 10 year study period. There were 163 men and 115 women with a median age of 70 years. The mean annual incidence of PEG procedures was 12.8/100.000. Sufficient medical data for evaluation was obtained from 263 patients. The most common indications were neurological disorders (61%) and malignancies (13%). Dementia accounted for only 0.8% of the indications. Total complication rate was 6.5% with 1.9% being major and 4.6% minor complications. Peritonitis was the most common (2.7%) complication followed by peristomal skin infection (1.9%). Operative mortality was 0.8% and 30 day mortality rate was 13%. In seven (2.7%) cases the PEG procedure was considered to be ethically and medically controversial.

Conclusion: This is the first published nationwide study on the experience of PEG procedures. The complication and mortality rates in Iceland are among the lowest reported. The indications reported here are in agreement with national guidelines with the rate of PEG procedures in ethically controversial cases being very rare.
