The site, either supra\u2010ampullary (above the ampulla of Vater) or trans\u2010ampullary (below the ampulla of Vater), may influence complication rates which significantly impact patient outcomes. This study evaluates the infection and obstruction rates associated with these two distinct stent placement strategies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data from 66 patients who underwent biliary stent placements between 2017 and 2022 at our institution were analysed. Patients were categorised into two groups based on stent placement: supra\u2010ampullary (12 patients) and trans\u2010ampullary (54 patients). We assessed the incidence of infection within 30 and 90\u2009days post\u2010procedure and in these patients evidence of radiological stent obstruction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the supra\u2010ampullary group, infection rates were 41.67% within 30\u2009days and 58.33% within 90\u2009days post\u2010procedure. The trans\u2010ampullary group exhibited infection rates of 12.96% within 30\u2009days and 20.37% within 90\u2009days. Higher infection rates were observed in the supra\u2010ampullary group at 30\u2009days, and this difference was statistically significant (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.020).
