Objective Gastrostomy facilitates artificial enteral feeding but controversy exists around associated morbidity and mortality. This study aimed to report short and long-term outcomes, and identify parameters associated with overall survival.

Methods A 7-year follow-up audit was undertaken at Aberdeen Royal Infirmary, UK. All patients undergoing endoscopic gastrostomy insertion October 2011–September 2018 were included. Last follow-up was February 2019. Clinical data were prospectively collected. Blood results were retrospectively obtained from electronic records. Statistical analysis was with IBM SPSS V.25.

Results 691 procedures were performed over the 7-year period (520 traditional pull-through percutaneous endoscopic gastrostomy (PEG) and 171 gastropexy procedures to facilitate gastrostomy). Frequency of complications (gastrointestinal bleeding, perforation and peritonitis) was low (each n=1). Overall 7-day and 30-day mortality was 2.2% and 8.4%, respectively. One-year mortality reached 47.6%. There was no difference in survival between PEG and gastropexy procedures (p=0.410). Multivariate analysis reported increased age (p<0.001), increased alkaline phosphatase (p<0.001) and clinical indication (p=0.002) as independently associated with an increased hazard of death. Only age was moderately predictive of mortality (area under the curve 0.74, 95% CI 0.70 to 0.78, p<0.001) in the PEG group. Clinical indication was the only parameter independently associated with mortality in the gastropexy cohort (p=0.003).

Conclusion Endoscopic gastrostomy placement can be safe with a low mortality and low risk of serious complications. Blood markers were not associated with short-term or long-term outcomes. Gastropexy to facilitate gastrostomy is a safe alternative to traditional pull-through PEG procedures. Future work should consider quality of life outcomes to assess the benefit of gastrostomy from a patient perspective.
