uncovered self expandable metal stents sems for Gastric Outlet Obstruction caused by stomach cancer
Clinical Endoscopy, 2008Co-Authors: Hyoungyeol Park, Dae Hwan Kang, Taiin Ha, Chan Ho Park, Cheolwoong Choi, Geunam SongAbstract:Background/Aims: The use of self-expandable metal stents (SEMS) is a safe and efficacious method for palliating malignant Gastric Outlet Obstruction. However, few reports have assessed clinical outcome after the insertion of SEMS for malignant Gastric Outlet Obstruction caused by stomach cancer. The aim of this study was to assess the usefulness of uncovered SEMS in patients with malignant Gastric Outlet Obstruction caused by stomach cancer. Methods: We evaluated 62 patients with Gastric Outlet Obstruction caused by stomach cancer treated by the implantation of uncovered SEMS. A total of 62 patients (43 males, 19 females) were treated between August 2000 and March 2007. A scoring system was used to grade the ability to eat. Results: Stent implantation was successful in 61 (98.4%) patients. Relief of obstructive symptoms was achieved in 49 (80.3%) patients. The mean survival duration was 143 days. The mean stent patency time was 103.5 days. An improvement in the ability to eat using the scoring system was statistically significant (p＜0.05). Conclusions: Endoscopic placement of uncovered SEMS is a safe and effective treatment for the palliation of patients with inoperable malignant Gastric Outlet Obstruction caused by stomach cancer.

treatment of Gastric Outlet Obstruction by stomach cancer with using double layered pyloric stent
Clinical Endoscopy, 2007Co-Authors: Dae Hwan Kang, Taiin Ha, Chan Ho Park, Cheulwoong Choi, Hyoungyoel Park, Geunam SongAbstract:Backgroud/Aims: Endoscopic stent placement is widely used to treat an unresectable malignant Gastric Outlet Obstruction. The covered stent has the disadvantage of an increased risk of migration, and the uncovered stent has an increased risk of ingrowth. This study examined the technical and clinical efficiency of stent placement of a double-layered combination pyloric stent that was newly designed to reduce tumor ingrowth and stent migration. Methods: Fifteen patients with a Gastric Outlet Obstruction caused by unresectable stomach cancer were treated with the endoscopic placement of a double-layered combination pyloric stent (an outer uncovered stent to reduce migration and an inner PTEF-covered stent to prevent tumor ingrowth). The technical success, clinical success, and complication especially tumor ingrowth and stent migration were analyzed. Results: Technical success was achieved in 15 out of 15 (100%) patients. Among the 15 patients in whom endoscopic stenting was placed successfully, the clinical success rate was 93.3%, the incidence of tumor ingrowth was 0%, the rate of migration was 6.7%, and tumor overgrowth was observed in 13.3%. The median stent patency period was 105 days. Conclusions: The placement of a double- layered pyloric combination stent appears to be effective in overcoming the disadvantage of the increased migration observed for a covered stent and the increased ingrowth observed for the uncovered stent.

cost comparison of gastrojejunostomy versus duodenal stent placement for malignant Gastric Outlet Obstruction
Journal of Gastroenterology, 2010Co-Authors: Suzanne M Jeurnink, Ewout W Steyerberg, Ernst J Kuipers, Peter D Siersema, Suzanne PolinderAbstract:Background Gastrojejunostomy (GJJ) and stent placement are the most commonly used palliative treatments for malignant Gastric Outlet Obstruction (GOO). In a recent randomized trial, stent placement was preferred in patients with a relatively short survival and GJJ in patients with a longer survival. As health economic aspects have only been studied in general terms, we estimated the cost of GJJ and that of stent placement in such patients.

cost comparison of gastrojejunostomy versus duodenal stent placement for malignant Gastric Outlet Obstruction
Journal of Gastroenterology, 2010Co-Authors: Suzanne M Jeurnink, Ewout W Steyerberg, Ernst J Kuipers, Peter D Siersema, Suzanne PolinderAbstract:Gastrojejunostomy (GJJ) and stent placement are the most commonly used palliative treatments for malignant Gastric Outlet Obstruction (GOO). In a recent randomized trial, stent placement was preferred in patients with a relatively short survival and GJJ in patients with a longer survival. As health economic aspects have only been studied in general terms, we estimated the cost of GJJ and that of stent placement in such patients. In the SUSTENT study, patients were randomized to GJJ (n = 18) or stent placement (n = 21). Pancreatic cancer was the most common cause of GOO. We compared initial costs and costs during follow-up. For cost-effectiveness, the incremental cost-effectiveness ratio was calculated. Food intake improved more rapidly after stent placement than after GJJ, but long-term relief of obstructive symptoms was better after GJJ. More major complications (P = 0.02) occurred and more reinterventions were performed (P < 0.01) after stent placement than after GJJ. Initial costs were higher for GJJ compared to stent placement (€8315 vs. €4820, P < 0.001). We found no difference in follow-up costs. Total costs per patient were higher for GJJ compared to stent placement (€12433 vs. €8819, P = 0.049). The incremental cost-effectiveness ratio of GJJ compared to stent placement was €164 per extra day with a Gastric Outlet Obstruction scoring system (GOOSS) ≥2 adjusted for survival. Medical effects were better after GJJ, although GJJ had higher total costs. Since the cost difference between the two treatments was only small, cost should not play a predominant role when deciding on the type of treatment assigned to patients with malignant GOO (ISRCTN 06702358).

stent versus gastrojejunostomy for the palliation of Gastric Outlet Obstruction a systematic review
BMC Gastroenterology, 2007Co-Authors: Suzanne M Jeurnink, Casper H J Van Eijck, Ewout W Steyerberg, Ernst J Kuipers, Peter D SiersemaAbstract:Gastrojejunostomy (GJJ) is the most commonly used palliative treatment modality for malignant Gastric Outlet Obstruction. Recently, stent placement has been introduced as an alternative treatment. We reviewed the available literature on stent placement and GJJ for Gastric Outlet Obstruction, with regard to medical effects and costs. A systematic review of the literature was performed by searching PubMed for the period January 1996 and January 2006. A total of 44 publications on GJJ and stents was identified and reported results on medical effects and costs were pooled and evaluated. Results from randomized and comparative studies were used for calculating odds ratios (OR) to compare differences between the two treatment modalities. In 2 randomized trials, stent placement was compared with GJJ (with 27 and 18 patients in each trial). In 6 comparative studies, stent placement was compared with GJJ. Thirty-six series evaluated either stent placement or GJJ. A total of 1046 patients received a duodenal stent and 297 patients underwent GJJ. No differences between stent placement and gastrojejunostomy were found in technical success (96% vs. 100%), early and late major complications 7% vs. 6% and 18% vs. 17%, respectively) and persisting symptoms (8% vs. 9%). Initial clinical success was higher after stent placement (89% vs. 72%). Minor complications were less frequently seen after stent placement in the patient series (9% vs. 33%), however the pooled analysis showed no differences (OR: 0.75, p = 0.8). Recurrent obstructive symptoms were more common after stent placement (18% vs. 1%). Hospital stay was prolonged after GJJ compared to stent placement (13 days vs. 7 days). The mean survival was 105 days after stent placement and 164 days after GJJ. These results suggest that stent placement may be associated with more favorable results in patients with a relatively short life expectancy, while GJJ is preferable in patients with a more prolonged prognosis. The paucity of evidence from large randomized trials may however have influenced the results and therefore a trial of sufficient size is needed to determine which palliative treatment modality is optimal in (sub)groups of patients with malignant Gastric Outlet Obstruction.
