Rationale: To measure local incidence proportions of one intra-procedural and nine post-procedural complications in the six months following gastrostomy insertion. The frequency of complications at the study centre were previously unknown.

Methods: The incidence proportion percentages were calculated through retrospectively searching through the electronic health records of the 108 adults who had an initial gastrostomy insertion between January and September 2024. Ethical approval was granted by the hospital organisation and the University of Greenwich, England.

Results: The sample population had a mean age of 65-years-old and the majority were male, of white ethnicity and had a normal body mass index between 18.5-24.9kg/m². The 30-day mortality rate was 4% [95% confidence interval (CI) 1, 9]. The six-month incidence proportion of perforation was 0%, peritonitis 0%, buried bumper syndrome 0%, leaking 1% [95% CI 0, 5], bleeding 8% [95% CI 4, 15], tube displacement 8% [95% CI 4, 15], infection 15% [95% CI 9, 23], aspiration pneumonia 20% [95% CI 14, 29] and overgranulation 22% [95% CI 15, 31]. The number of balloon-retained gastrostomies that became unintentionally displaced was statistically higher than the number of bumper-retained gastrostomies (p = 0.01).

Conclusion: In comparison with peer-reviewed studies published over the last decade, the study centre outperformed other centres worldwide for five of the complications (30-day mortality, perforation, peritonitis, tube displacement and buried bumper syndrome), performed in line with other centres for one complication (leaking) and performed less well than others for four complications (infection, bleeding, aspiration pneumonia and overgranulation). These findings can be used to identify future local quality improvement projects, including the review of internal gastrostomy policies and both patient and staff educational materials.
