Dual interventions for advanced gastric cancer with pyloric obstruction: a report of one case

This paper reports the application of dual interventions in the treatment of a case of advanced gastric cancer with pyloric obstruction. Stent placement was performed to alleviate the obstructive symptoms, resume oral intake, and improve the quality of life, while embolization with gelatin sponge particles was performed to control cancer progression and prevent stent restenosis. Good effects were achieved in this case. Embolization with gelatin sponge particles not only controls tumor progression but also reduces the risk of gastric necrosis and perforation.

Treatment of anastomotic malignant obstructions after gastric cancer surgery with self-expanding metallic stents: an analysis of 15 cases

AIM: To assess the feasibility, effectiveness and complications of the placement of expandable metallic stents in patients with anastomotic obstruction following gastric cancer surgery.

METHODS: Under the guide of X-ray and gastroscopy, 15 cases with anastomotic obstruction due to gastric cancer surgery were placed with metallic stents. An evaluation of placement skills, clinical success rate and complications was conducted as well as survival duration and stent patent rate were calculated in Kaplan-Meier analysis.

RESULTS: Stent placement was technically successful in 13 out of 15 patients (86.7%). After stent placement, 12 patients (92.3%) experienced remarkable improvement of symptoms. In the follow-up (2-66 wk), abdominal pain occurred in 3 cases (23%), stent removal in 2 cases (15.4%), stent obstruction due to tumor overgrowth in 1 case (8%) and gastrointestinal bleeding in 2 cases (15.4%). The median survival duration and stent patent period were 87.0 and 140.0 d respectively.

CONCLUSION: Placement of metallic stents in patients with anastomotic stenosis due to gastric cancer surgery is technically feasible, safe, and clinically effective. It is also beneficial to improve patients' quality of life, although complications may occur in some cases.
