Presenting Symptoms

ABSTRACTGastric outlet obstruction (GOO) is usually a late presentation of gastric cancer, pancreaticobiliary malignancy, and extrinsic lymph nodal compression. Presenting symptoms are abdominal pain, postprandial epigastric fullness, and recurrent vomiting, which lead to severe malnutrition and dehydration and poor quality of life (QoL). Endoscopic enteral stent placement has become the acceptable alternative modality for palliation of malignant GOO because it is safe, minimally invasive, and a cost-effective procedure. In addition, endoscopic stent placement leads to shorter time to resume oral diet and shorter hospital stay in comparison to surgical bypass. Endoscopic stent placement is associated with high technical as well as clinical success rates and improvement in QoL, but no survival improvement. Recurrence of symptoms occurs due to stent occlusion, or stent migration, which can be successfully managed with repeat endoscopic stent placement. Perforation and bleeding are serious but rare complications.

Abstract Introduction We recently developed a double-balloon device, using widely available existing technology, to facilitate endoscopic ultrasound-guided gastroenterostomy (EUS-GE). Our aim is to assess the feasibility of this modified approach to EUS-guided double-balloon-occluded gastroenterostomy bypass (M-EPASS). Methods This was a single-center retrospective study of consecutive patients undergoing M-EPASS from January 2019 to August 2020. The double-balloon device consists of two vascular balloons that optimize the distension of a targeted small-bowel segment for EUS-guided stent insertion. The primary end point was the rate of technical success. Results 11 patients (45 % women; mean [standard deviation (SD)] age 64.9 [8.6]) with malignant gastric outlet obstruction were included. Technical and clinical success (ability to tolerate an oral diet) were achieved in 91 % (10/11) and 80 % (8/10) of patients, respectively. There was one adverse event (9 %) due to stent migration. Two patients (18 %) required re-intervention for stent obstruction secondary to food impaction. The mean (SD) time to a low residue diet was 3.5 (2.4) days. Conclusion M-EPASS appears to facilitate the technique of EUS-GE, potentially enhancing its safety and clinical adoption. Larger studies are needed to validate this innovative approach to gastric outlet obstruction.

AbstractMigration of duodenal covered self-expandable metal stents (C-SEMSs) is the main cause of stent dysfunction in patients with malignant gastric outlet obstruction (mGOO). Because endoscopic SEMS placement is frequently selected in patients with poor performance status, we concurrently focused on the safety of the treatment. This pilot study included 15 consecutive patients with mGOO who underwent duodenal partially covered SEMS (PC-SEMS) placement with fixation using an over-the-scope-clip (OTSC). Technical feasibility, clinical success for oral intake estimated by the Gastric Outlet Obstruction Scoring System (GOOSS) score, and adverse events including stent migration were retrospectively assessed. All procedures were successful, and clinical success was achieved in 86.7% (13/15). Mean GOOSS scores were improved from 0.07 to 2.53 after the procedure (P < 0.001). Median survival time was 84 days, and all patients were followed up until death. Stent migration occurred in one case (6.7%) at day 17, which was successfully treated by removal of the migrated PC-SEMS using an enteroscope. For fixation using an OTSC, additional time required for the procedure was 8.9 ± 4.1 min and we did not observe OTSC-associated adverse events. Poor performance status was associated with clinical success (P = 0.03), but we could provide the treatment safely and reduce mGOO symptoms even in patients with poor performance status. In conclusion, duodenal PC-SEMS fixation using an OTSC is feasible for preventing stent migration in patients with mGOO including those with poor performance status.

Abstract Migration of duodenal covered self-expandable metal stents (C-SEMSs) is the main cause of stent dysfunction in patients with malignant gastric outlet obstruction (mGOO). Because endoscopic SEMS placement is frequently selected in patients with poor performance status, we concurrently focused on the safety of the treatment. This pilot study included 15 consecutive patients with mGOO who underwent duodenal C-SEMS placement with fixation using an over-the-scope-clip (OTSC). Technical feasibility, clinical success for oral intake estimated by the Gastric Outlet Obstruction Scoring System (GOOSS) score, and adverse events including stent migration were assessed. All procedures were successful, and clinical success was achieved in 86.7% (13/15). Mean GOOSS scores were improved from 0.07 to 2.53 after the procedure (P < 0.001). Stent migration occurred in one case (6.7%) with no other adverse events. For fixation using an OTSC, additional time required for the procedure was 8.9 ± 4.1 minutes. Poor performance status was associated with clinical success (P = 0.03), but we could provide the treatment safely and reduce mGOO symptoms even in patients with poor performance status. In conclusion, duodenal C-SEMS fixation using an OTSC is feasible for preventing stent migration in patients with mGOO including those with poor performance status.

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 and study aim Use of endoscopic ultrasound-guided biliary drainage (EUS-BD) has recently increased. In EUS-BD, after puncturing the bile duct, dilation is performed and the stent is deployed. Due to adverse events (AEs) such as unexpected displacement of the guidewire, simplified procedures are required. Currently, stents with small-diameter delivery systems are being rapidly developed, expanding the possibilities for of EUS-BD without dilation. In this retrospective study, we aimed to evaluate the success rates and AEs in patients who underwent EUS-guided hepaticogastrostomy (EUS-HGS) or EUS-guided hepaticojejunostomy (EUS-HJS) without dilation. Patients and methods Six consecutive patients with malignant biliary obstruction and failed transpapillary BD underwent EUS-HGS or EUS-HJS without dilation, deploying a 6-mm fully-covered self-expandable metallic stent with a 6-Fr delivery system. Results The technical and clinical success rates were 100 %. There was one case each of stent migration and stent occlusion, and no other AEs were noted. Conclusions EUS-HGS or EUS-HJS without dilation using a stent with a 6-Fr delivery system had high technical and clinical success rates; however, additional cases are required to validate the study findings.

We aimed to review our experiences to evaluate the practicality, safety, and effectiveness of endoscopic stent placement for the palliation of malignant obstructions of the upper gastrointestinal system (GIS) and the treatment of postoperative complications such as failure of anastomoses and fistulae. Endoscopic stent placement is increasingly used in the upper GIS for the management of both high grade malignancies causing obstruction and benign pathologies such as anastomosis failures, gastrointestinal fistulae, and strictures. Hospital records, clinical data, and endoscopy reports of 61 patients who had undergone endoscopic stenting between the years 2012 and 2015 were analyzed retrospectively. For all patients, self-expandable metal covered stents were used. Data involving technical and clinical success rates, complication, morbidity, and mortality rates of the endoscopic stenting procedure was collected and simple statistical analyses were made. Endoscopic stenting was successful in 60 of 61 patients (98.3%). Overall technical success rate was found to be 98.3%; clinical success rate, 86.6%; complication rate, 4.9%. No stent related mortality was observed in our series. Endoscopic stents can be effectively and safely used in the treatment of various lesions of the upper GIS.
