Factors Leading to Improved Results for Endoscopic Stenting for Metastatic Antropyloric Adenocarcinoma. A Comparison with Gastrojejunostomy.

BACKGROUND

Controversies exist about the optimal palliative management for patients with metastatic antropyloric adenocarcinoma. The aim of this study was to analyse the clinical outcome for patients with gastric outlet obstruction syndrome and metastatic antropyloric adenocarcinoma, who underwent endoscopic stenting or open gastrojejunostomy, in a prospective not randomised study.

MATERIAL: The clinical course and costs for 70 patients who had endoscopic stenting and for 30 patients who had in the same period a gastrojejunostomy for gastric outlet obstruction syndrome due to metastatic adenocarcinoma of the antropyloric region were prospectively analysed.

RESULTS

Hospital stay and time to resume oral feeding was shorter in patients who had endoscopic stenting (p < 0.05). Overall costs for endoscopic stenting were lower than those for gastrojejunostomy (11,000 versus 21,000 euros). Comparing patients who survived more than 6 months, costs between endoscopic stenting and gastrojejunostomy were similar (21,000 versus 22,000 euros).

CONCLUSIONS

Endoscopic placement of metallic stents offers an effective therapy in patients with advanced primay adenocarcinoma of the antropyloric region and poor general conditions. In patients with longer life expectancy, surgical gastroenterostomy has still a major role. In contrast to previous reports, costs for endoscopic stenting are similar to those of gastrojejunostomy in patients with longer life expectancy. Laparoscopic gastrojejunostomy has the theoretical advantage to reduce these costs with a less invasive procedure. Results for endoscopic stenting have improved significantly in recent years.
