Second Covered and Uncovered Self-Expandable Metal Stents for Recurrent Gastric Outlet Obstruction: A Retrospective Comparative Study. J Clin Med 2023; 12:5241. [PMID: 37629282 PMCID: PMC10455318 DOI: 10.3390/jcm12165241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2023] [Revised: 08/01/2023] [Accepted: 08/07/2023] [Indexed: 08/27/2023] Open
Abstract
Background: Endoscopic self-expandable metal stent (SEMS) placement is a current mainstay for malignant gastric outlet obstruction (GOO), but symptomatic recurrence due to initial SEMS dysfunction commonly occurs. We aimed to compare the safety and effectiveness of second SEMS for recurrent GOO (RGOO). Methods: Between April 2006 and December 2022, a total of 95 cases with malignant RGOO undergoing second endoscopic SEMS placement were enrolled. Technical and clinical success rates, RGOO, time to RGOO (TRGOO), stent patency rate, adverse events (AE), and overall survival (OS) were retrospectively compared between covered and uncovered SEMS (cSEMS/uSEMS) groups. Risk factors for TRGOO were also explored. Results: Baseline characteristics were well balanced between cSEMS (n = 48) and uSEMS (n = 47) groups, except for the causes of the initial SEMS dysfunction. High technical and clinical success rates with a similar incidence of AE (15% vs. 17%, p = 0.78) and OS (median of 101 vs. 102 days, p = 0.68) were achieved in both groups. There were no statistical differences in cumulative incidence of RGOO (19% vs. 13%, p = 0.58), TRGOO (median, not reached in both groups, p = 0.57), and stent patency rates at 1, 2, and 3 months between the groups (60%, 47% and 26%, respectively vs. 70%, 55% and 38%, respectively). However, TRGOO tended to be longer in cSEMS in cases with RGOO due to tumor ingrowth (median, not reached vs. 111 days, p = 0.19). A Cox regression analysis demonstrated that chemotherapy after second SEMS placement was significantly associated with an improved TRGOO (the hazard ratio of 0.27 [95% confidence interval, 0.08-0.93], p = 0.03). Conclusions: Regardless of the type of SEMS, second SEMS placement was similarly safe and effective for RGOO. The type of second SEMS might be considered based on the cause of initial SEMS dysfunction.

Abstract
BACKGROUND Outcomes of partially covered self-expandable metal stents (SEMS) as an additional stent after recurrent duodenal obstruction (RDO) have not been elucidated. In this study, we compared outcomes of partially covered and uncovered SEMS placement after RDO in patients with malignant duodenal obstruction and explored factors affecting re-recurrent obstruction and overall survival in this population. METHODS We conducted a retrospective study of patients undergoing SEMS placement for RDO at a cancer institute in Japan from July 2014 to June 2021. Clinical variables and outcomes of patients undergoing partially covered and uncovered SEMS placement were compared. RESULTS Sixty-one patients underwent SEMS placement after RDO, for which the COMVI stent was used in 38 cases and uncovered stents were used in 23 cases. Stent ingrowth was the most common cause of RDO (51.4%). Stent migration only occurred after partially covered stent placement (20% vs. 0%, p = 0.018). Choice of SEMS had no impact on time to re-RDO (median 2.8 vs. 4.1 months, p = 0.776) or overall survival (median 2.6 vs. 2.4 months, p = 0.703). Median overall survival was longer in patients receiving chemotherapy after second stenting (4.6 vs. 1.8 months, p < 0.001) and shorter in those with early RDO, regardless of the SEMS used. Use of the partially covered stent had no impact on survival or time to RDO. CONCLUSIONS While outcomes after partially covered SEMS placement for RDO were not significantly different from uncovered SEMS, migration remains a concern when they are used as a second stent. Chemotherapy after second stenting was associated with longer overall survival but not with longer time to re-RDO.

Abstract
Background Self-expanding metal stents (SEMS) have been used for the palliative treatment of malignant gastrointestinal tract obstruction. However, restenosis or incomplete expansion of a first stent is a frequent complication, and the effectiveness of reintervention with placement of a second stent is still controversial. Objective To evaluate the clinical outcomes of covered SEMS (cSEMS) placement after dysfunction of uncovered SEMS (uSEMS) by the stent-in-stent technique. Patients and Methods We retrospectively studied a consecutive series of patients receiving palliative treatment for malignant gastrointestinal obstruction with cSEMS placement after uSEMS dysfunction in a tertiary center from January 2013 to August 2018. Technical and clinical success, time of patency, and adverse events were analyzed. Results Twelve patients were included; their mean age was 60 ± 9 years. Eleven patients had gastric outlet obstruction, and 1 patient had compression of the transverse colon due to gastric neoplasia. In 5 cases, there was absence of early clinical success with uSEMS and stent dysfunction in 7 cases (median patency time: 81 days). There was 100% technical success and 91.7% clinical success after cSEMS placement. There were no adverse events nor need for reintervention. The median patency time after placement of both stents was 163 days (vs. 71 days with the initial stent). Conclusion cSEMS placement after uSEMS dysfunction is technically feasible and a clinically effective treatment for patients with recurrent malignant gastrointestinal obstruction, with good stent patency in the medium/long term. This approach seems to be safe and without increase in adverse effects.

Abstract
Self-expandable metallic stent (SEMS) placement is widely used for relieving symptoms in malignant gastric outlet obstruction (MGOO). This study aimed to evaluate the efficacy and safety of multiple gastroduodenal stent placement using the stent-in-stent technique and to identify factors predictive of stent patency.We retrospectively analyzed data from 170 patients with GOO receiving SEMS using the stent-in-stent technique between July 2006 and July 2018. Of these, 90 had been treated with SEMS placement for MGOO. Technical and clinical success rates were evaluated. Clinical outcomes and predictors of stent patency were also analyzed.Second SEMS placement was used in 34.4% of cases and 9.7% were treated with third SEMS placement because of prior stent dysfunction. Median stent patency time was 15.7 weeks for the first SEMS, 10.4 weeks for the second, and 11.3 weeks for the third. The technical and clinical success rates were 100% and 97.8% for the first SEMS, 100% and 90.3% for the second, respectively, and both 100% for the third. Multivariable analysis showed that use of covered SEMS and chemotherapy after first and second SEMS placement was significant predictors of stent patency. Serious complications such as bleeding or perforation did not occur in any patient.Second and third gastroduodenal SEMS placement using the stent-in-stent technique is safe and effective for management of first stent dysfunction in MGOO. Stent patency is significantly associated with the use of covered SEMS and chemotherapy after SEMS placement.

Abstract
BACKGROUND Patients with pancreatic adenocarcinoma may develop into duodenal obstruction during the course of their disease. The diagnosis of obstruction can be generally achieved by means of imaging technologies. Case and Outcome We reported a rare case of pancreatic tumor with duodenal obstruction accompanied by obstructive symptoms, which was finally confirmed by laparotomy. A 68-year-old man was admitted to our department with a 3-day medical history of upper abdominal pain, nausea and vomiting. The diagnosis of duodenal obstruction was established by means of various imagings including computed tomography (CT) scan, gastroscopy and upper gastrointestinal imaging. Upper gastrointestinal imaging and magnetic resonance imaging (MRI) showed extrinsic tumor mass was noted at the second and third portion of the duodenum accompanied by duodenal obstruction and dilatation, respectively. Laparotomy confirmed a tumor mass arising from the head and uncinate process of pancreas, which had invaded the second and third portions of the duodenum and caused closed loop obstruction. A pancreaticoduodenectomy (Whipple procedure) was performed followed by therapeutic trade-off according to intraoperative exploration. Postoperative histopathology revealed pancreatic tumor only infiltrated duodenal wall, while resection margins of pancreas, common bile duct and duodenum were all negative. The patient was cured and discharged home 12 days after surgery. CONCLUSION The present case indicated radical operation in our study appeared to be the first choice treatment for patients with malignant duodenal obstruction.

Abstract
BACKGROUND AND AIMS Self-expanding metal stents (SEMS) have been used for the palliative treatment of malignant gastric outlet obstruction (GOO). The aim of this study was to evaluate the clinical outcomes of salvage SEMS for stent malfunction and to identify the prognostic factors for a longer patency. METHODS A total of 108 patients who underwent a secondary salvage SEMS placement for a primary stent malfunction were retrospectively reviewed at the Seoul National University Hospital between August 2004 and May 2013. The duration of patency for salvage SEMS was defined as the time between salvage SEMS placement and the recurrence of obstructive symptoms that were confirmed either endoscopically or radiologically. RESULTS The technical and clinical success rates for salvage SEMS were 100 and 82.4% (95% confidence interval [CI] 74.0-89.0), respectively. A salvage SEMS malfunction occurred in 29 (26.9%) of the 108 patients. The median duration of patency for salvage SEMS was 59.5 days (range 3-928, 95% CI 73.7-118.3). Longer SEMS patencies of more than 60 days were significantly associated with palliative chemotherapy (odds ratio = 2.539, 95% CI 1.031-6.252, p = .043). For salvage SEMS, covered-uncovered stents had a longer patency duration, as compared with other combinations of primary and salvage stent types. CONCLUSIONS Longer patency durations for salvage SEMS were associated with palliative chemotherapy after salvage SEMS insertion. Salvage SEMS could be a feasible and effective treatment for primary stent malfunction in malignant GOO.

Abstract
BACKGROUND AND AIM To evaluate the efficacy and safety of secondary gastroduodenal stent placement after first stent dysfunction for malignant gastric outlet obstruction. METHODS We conducted a retrospective analysis to investigate the efficacy and safety of secondary stent-in-stent gastroduodenal stent placement. RESULTS Among 260 patients who had been treated with first gastroduodenal stent placement for malignant gastric outlet obstruction, 29 patients (11.2%) were treated with secondary gastroduodenal stent placement because of first stent dysfunction. Pancreatic cancer was the major primary cancer (55.2%). A WallFlex duodenal stent was the most frequently inserted stent both as a first stent (75.9%) and as a secondary stent (62.1%). There were 22 patients (75.9%) that received gastroduodenal stents at the bending site (supraduodenal angle or infraduodenal angle). Technical and clinical success rates were 100% and 86.2%, respectively. Median eating period was 3.0 months, and median survival time was 3.5 months. As for related complications, gastrointestinal perforation, insufficient stent expansion, tumor ingrowth, tumor overgrowth, and cholangitis were experienced in 13.8% (four cases), 6.9% (two cases), 6.9% (two cases), 3.4% (one case), and 3.4% (one case), respectively. CONCLUSION Secondary gastroduodenal stent placement might be effective for managing first stent dysfunction in malignant gastric outlet obstruction. However, gastrointestinal perforation was the major complication.

Gastroduodenal stenting with Niti-S stent: long-term benefits and additional stent intervention. Dig Endosc 2015; 27:121-9.

Abstract
BACKGROUND AND AIM Self-expandable metallic stents have mainly been used for the palliation of malignant gastric outlet obstruction (GOO). However, their use in long-term survivors and the feasibility, safety and benefit of additional intervention for stent dysfunction remain controversial. The present study examined the long-term benefits of endoscopic gastroduodenal stenting. METHODS We reviewed 61 patients treated with Niti-S stents at several hospitals and estimated the efficacy of stent intervention, stent patency, eating period and factors related to poor effectiveness. RESULTS All 61 first stent interventions and 14 additional stent interventions (11 second interventions and 3 third interventions) were successfully carried out. Clinical success rates were 83.6% and 85.7%, and median stent patency was 214 days and 146 days (P = 0.47), respectively. Fifty patients could be treated with a first stent only, and 11 patients received additional stents. At the time of study termination or death, 70.0% of the former group and 63.6% of the latter group maintained oral intake (P = 0.71), and each 86% and 100% among the group could maintain oral intake for a period exceeding half of their remaining lives after first stent intervention. Karnofsky performance status ≤50 (P = 0.03), ascites (P = 0.009), and peritoneal dissemination (P = 0.001) appeared to be factors related to poor effectiveness. CONCLUSIONS Despite the presence of factors related to poor effectiveness, endoscopic gastroduodenal stenting would be the first treatment of choice for GOO and provide long-term benefits. If stent dysfunction occurs, additional stent intervention enables continued oral intake safely.
