title: Stent implantation technique through PEG-like pathway for treatment of malignant gastroduodenal obstruction.
abstract: OBJECTIVE
  To investigate feasibility and safety of stent implantation technique through percutaneous endoscopic gastrostomy (PEG)-like pathway for treatment of malignant gastroduodenal obstructions.
  
  
  METHODS
  Twelve patients with malignant gastroduodenal obstructions accepted PEG-like operations. A stent implantation pathway was established in abdominal wall under endoscopic guide. A guide wire and a stent release device were introduced through this pathway followed by an intestinal stent implantation. After operation, efficacy and safety of this technique were assessed by collecting data such as operation time, complications, postoperative medication, and hospitalization time during postoperative 2-12 months of follow-up.
  
  
  RESULTS
  Twelve patients were successfully treated with stent implantation technique through PEG-like pathway for the first time. The average operation time was 31 minutes. No severe complications occurred during treatment. On the fourth days after operation, patents were give liquid diet and treatment of rehydration, acid suppression, hemostasis and anti-inflammation. The average hospitalization time was 5 days. The follow-up time was 2-12 months. Twelve (100%) patients achieved complete remissions. The stent related complications and obstruction did not appear within 2 months after operations. The quality of life improved significantly.
  
  
  CONCLUSIONS
  The stent implantation technique through PEG-like pathway for treatment of malignant gastroduodenal obstruction is a feasible, effective, and safe choice.
