Abstract
Endoscopic placement of self-expandable metal stent (SEMS) is an efficient method for the palliative decompression of malignant gastro duodenal obstruction. However, its role in treating benign obstructive conditions is controversial. We herein present an unusual case of recurrent upper gastrointestinal (GI) bleeding episodes due to ischemic lesions induced by an uncovered SEMS placed several years before to treat post peptic ulcer pyloric obstruction. Patient's advanced age precluded any attempt for endoscopic or surgical removal of the stent and the patient was successfully treated only with proton pump inhibitors, remaining uneventful on the long term. This case speaks to the need for rational use of innovative treatment modalities for quality of care provision.

Abstract
Gastric outlet obstruction (GOO) is one of severe comorbidities caused by many kinds of malignant diseases and is associated with not only degradation of patients' quality of life but also mortality. Although surgical bypass is one of the main therapies for malignant GOO, it is often difficult to perform in end-stage patients. The deployment of self-expandable metallic stents (SEMSs) has recently become a viable alternative to surgical bypass for malignant GOO. This technique is less invasive and more effective, particularly in patients with poor prognoses. Many reports have referred to the feasibility, effectiveness, and safety of the placement of SEMSs for malignant GOO. According to these reports, the rates of technical and clinical success were reported to be relatively high and the rate of adverse events to be acceptable. However, precautions against severe adverse events such as massive bleeding and perforation are necessary. Several reports have described the differences in clinical results among different kinds of SEMSs. The presence of a covered design for SEMSs may affect the patency of SEMSs and the rate of stent dysfunction. Selection of the SEMS according to axial force may affect successful achievement of long patency of SEMSs and avoidance of gastroduodenal perforation at the bending site of the duodenum. Compared with high technical success rates nearing 100%, clinical success rates were usually lower than technical success. Therefore, determination of predictive factors for failure of clinical success is important. Several papers reported that low performance status could be associated with failure of clinical success. However, the association of clinical success with other factors such as carcinomatosa and ascites remains controversial, which is a problem to be solved. Reintervention with SEMS using the stent-in-stent method after stent dysfunction can be performed effectively as well as placement of the first SEMS.

Outcome of self-expandable metallic stent deployment in patients with malignant gastroduodenal outlet obstruction and Niti-S and WallFlex comparison: a multicenter retrospective clinical study. J Dig Dis 2016; 17:518-525. [PMID: 27383654 DOI: 10.1111/1751-2980.12377] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2016] [Revised: 06/20/2016] [Accepted: 06/30/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Several studies report on the outcomes of self-expandable metallic stents (SEMSs) deployment for malignant gastric outlet obstruction (GOO). However, data was mostly based on the analysis of single-center studies including only a small number of patients. This study aimed to evaluate clinical outcomes after the deployment of SEMS in patients with malignant GOO and to compare the clinical outcomes of two metallic stents with different designs. METHODS Altogether 125 consecutive patients from five institutions were included. Clinical outcomes were evaluated according to technical success, clinical success, stent patency period, survival period and complications. A comparison of clinical outcomes between Niti-S pyloric/duodenal and WallFlex duodenal stents was also undertaken. RESULTS Rates for clinical and technical success were 100% and 92.0%, respectively. The median stent patency and survival periods were 72.0 days (range 3-775 days) and 75.0 days (range 3-775 days), respectively. The rate of overall adverse events was 28.8%. The rate of stent dysfunction was 16.8%, and that of adverse events, except stent dysfunction was 12.0%. Massive bleeding occurred in two patients as a late complication. The clinical success rate for Niti-S stent was significantly higher than that for WallFlex stent (96.2% vs 84.8%, P = 0.023). CONCLUSIONS We successfully deployed a SEMS in malignant GOO. The selection of a SEMS with a lower axial force may be important for patients to resume the oral food intake. Additionally, consideration must be given to the appropriate management of fatal bleeding as a late complication.
