AbstractAcute colorectal obstruction has been often reported as a secondary outcome of left-colonic malignancy. It is considered as a common emergency condition. Self-expandable metallic stent (SEMS) placement is widely used as a palliative treatment for the management of malignant colorectal obstruction (MCRO). SEMS placement is also deliberated as a bridge to surgery. With advances in technology, several recent studies of SEMS placement for MCRO indicated high technical (94–98%) and clinical (91–93%) success rates. The complication rate associated with SEMS is quite acceptable. However, long-term outcomes are still unclear. The symptoms should be carefully monitored before application of SEMS, particularly in patients who are eligible for systemic chemotherapy and in patients with a long life expectancy because of late complications such as reobstruction, stent migration, and perforation. Appropriate patient selection and placement technique are keys for the successful implementation of SEMS.

88 Background: Self-expandable metallic stent (SEMS) placement is widely used for relieving the obstructive symptoms of malignant gastric outlet obstruction (MGOO). The aims were to evaluate the efficacy and safety of multiple gastroduodenal stent placement by stent in stent technique and identify predictive factors about stent patency. Methods: We retrospectively analyzed data from 170 patients with GOO receiving SEMS by stent in stent technique from July 2006 to July 2018. Among them, 90 patients had been treated with gastroduodenal SEMS placement for MGOO. Technical and clinical success rates were evaluated. And, clinical outcomes with predictors of stent patency were also analyzed. Results: Among the subjects, 34.4% were treated with secondary SEMS placement, and 9.7% were treated with third SEMS placement because of the previous stent dysfunction. The median stent patency time was 15.7 weeks (range 0-89) in the first SEMS, 10.4 weeks (range 0-44) in the second SEMS, and 11.3 weeks (range 1-29) in the third SEMS. The technical and clinical success rate were 100% and 97.8% in the first SEMS, 100% and 90.3% in the second SEMS, 100% and 100% in the third SEMS. In multivariable analysis, the first SEMS placement of covered type including Comvi stent was correlated with prolonged stent patency (OR 4.549, P = 0.001). And both chemotherapy after the first SEMS placement (OR 8.248, P = 0.006) and chemotherapy after the second SEMS placement (OR 7.467, P = 0.003) were correlated with prolonged stent patency. Serious complications such as gastrointestinal hemorrhage or perforation did not occur in any patient. Conclusions: Secondary and third gastroduodenal SEMS placement by stent in stent technique is a safe and effective treatment for the first stent dysfunction in MGOO. The stent placement of covered type and chemotherapy after stent placement is the predictor of stent patency.

Abstract Background: Bridge to surgery (BTS) using a self-expandable metallic stent (SEMS) for the treatment of obstructive colorectal cancer improves the patient’s quality of life. This study aimed to examine prognostic factors of obstructive colorectal cancer. Methods: We analyzed stage II-III resectable colon cancer cases (Cur A) retrospectively registered between January 2005 and 2017. We encountered Cur A cases after BTS with SEMS placement (BTS group). We compared surgical results and prognoses between the two groups. Results: A total of 50 patients underwent endoscopic SEMS placement, which technical success of 96% and morbidity rate of 18%. Overall, 117 patients were evaluated: 67 of them underwent emergency surgery (ES) and 50 underwent BTS. Primary anastomosis rates were 77.6% in ES and 95.7% in BTS (p < 0.001); postoperative complication, 46.3% in ES and 10.5% in BTS (p < 0.001); pathological findings of lymphatic invasion, 66.7% in ES and 100% in BTS (p < 0.001); venous invasion were 66.8% in ES and 92% in BTS (p = 0.04); and recurrence of 25.4% in ES and 39.1% in BTS. The 3-year overall survival was significantly different between two groups (ES, 86.8%:BTS, 58.8%), BTS is worse than ES (log-rank test; p < 0.001). Venous invasion independently predicted worsened recurrence-free and overall survival. Conclusions: The vascular invasiveness was correlated with tumor progression after SEMS placement, and the survival rate was lower in BTS. SEMS potentially worsens prognostic outcomes in stage II–III obstructive colorectal cancer.

Objectives: To retrospectively evaluate the safety and efficacy of transcatheter arterial embolization (TAE) for delayed arterial bleeding secondary to percutaneous self-expandable metallic stent (SEMS) placement in patients with malignant biliary obstruction (MBO). Methods: From January 1997 to September 2017, 1858 patients underwent percutaneous SEMS placement for MBO at a single tertiary referral center. Among them, 19 patients (mean age, 70.2 [range, 52–82] years; 13 men) presented with delayed SEMS-associated arterial bleeding and underwent TAE. Results: The incidence of delayed arterial bleeding was 1.0% (19/1858) after SEMS placement, with a median time interval of 225 days (range, 22–2296). Digital subtraction angiography (DSA) showed pseudoaneurysm alone close to the stent mesh (n = 10), pseudoaneurysm close to the stent mesh with contrast extravasation to the duodenum (n = 3), pseudoaneurysm close to the stent mesh with arteriobiliary fistula (n = 1), in-stent pseudoaneurysm alone (n = 4) and in-stent pseudoaneurysm with arteriobiliary fistula (n = 1). Bleeding was stopped after the embolization in all patients. Overall clinical success rate was 94.7% (18/19). One patient with recurrent bleeding was successfully treated with a second embolization. Overall 30-day mortality rate was 26.3% (5/19). A major procedure-related complication was acute hepatic failure in one hilar bile duct cancer patient (5.3%), which was associated with an obliterated portal vein. Conclusion: TAE is safe and effective for the treatment of delayed arterial bleeding after percutaneous SEMS placement for MBO. Advances in knowledge: This study demonstrated TAE is safe and effective for arterial bleeding after SEMS placement after MBO through the largest case series so far.
