Abstract
BACKGROUND Palliative endoscopic stent placement may be considered in patients with malignant gastrointestinal obstruction. Stent migration is a potential complication, particularly for those placed at a surgical anastomosis or across a stricture caused by extra-alimentary tract factors. We report a patient with left renal pelvis cancer and gastrojejunostomy obstruction who underwent endoscopic stent placement and laparoscopic stent fixation. CASE PRESENTATION A 60-year-old male with peritoneal dissemination of a left renal pelvis cancer was admitted for treatment of upper gastrointestinal obstruction. A laparoscopic gastrojejunostomy had been previously performed for cancer invasion of the duodenum. Imaging showed gastroduodenal dilation and impaired passage of contrast medium through the efferent loop of the gastrojejunostomy. Gastrojejunostomy anastomosis site obstruction due to dissemination of left renal pelvis cancer was diagnosed. Conservative treatment failed and endoscopic stent placement with laparoscopic stent fixation was performed. After surgery, the patient was able to tolerate oral intake and he was discharged without complications. The patient gained weight and was able to resume chemotherapy, indicating the procedure was effective. CONCLUSIONS Endoscopic stent placement with laparoscopic stent fixation for malignant upper gastrointestinal obstruction appears effective in patients with a high risk of stent migration.

Palliative Surgery or Metallic Stent Positioning for Advanced Gastric Cancer: Differences in QOL. ACTA ACUST UNITED AC 2021; 57:medicina57050428. [PMID: 33925171 PMCID: PMC8146574 DOI: 10.3390/medicina57050428] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 04/12/2021] [Accepted: 04/27/2021] [Indexed: 12/12/2022]
Abstract
Background and Objectives: Twenty percent of the patients affected with stage IV antropyloric stomach cancer are hospitalized with a gastric outlet obstruction syndrome (GOOS) requiring its resolution to improve the quality of life (QoL). We present our preliminary short- and mid-term results regarding the influence of endoscopic placement of self-expandable metal stent (SEMS) or open stomach-partitioning gastrojejunostomy in QoL. Materials and Methods: In this prospective randomized longitudinal cohort trial, we randomly assigned 27 patients affected with stage IV antropyloric stomach cancer into two groups: Group 1 (13 patients) who underwent SEMS positioning and Group 2 (14 patients) in whom open stomach-partitioning gastrojejunostomy was performed. The Karnofsky performance scale and QoL assessment using the EQ-5D-5L™ questionnaire was administered before treatment and thereafter at 1, 3, and 6 months. Results: At 1-month, index values showed a statistically significant deterioration of the QoL in patients of Group 2 when compared to those of Group 1 (p = 0.004; CI: 0.04 to 0.21). No differences among the groups were recorded at 3-month; whereas, at 6-month, the index values showed a statistically significant deterioration of the QoL in patients of Group 1 (p = 0.009; CI: −0.25 to −0.043). Conclusions: Early QoL of patients affected with stage IV antropyloric cancer and symptoms of GOOS is significantly better in patients treated with SEMS positioning but at 6-month the QoL significantly decrease in this group of patients. We explained the reasons of this fluctuation with the higher risk of re-hospital admission in the SEMS group.

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.

Comparison on the Efficacy between Partially Covered Self-Expandable Metal Stent with Funnel-Shaped Enlarged Head versus Uncovered Self-Expandable Metal Stent for Palliation of Gastric Outlet Obstruction. Gastroenterol Res Pract 2018; 2018:4540138.

Abstract
Background Shape modification has been one of the methods adopted to improve stent patency but has not always translated into positive outcome. The aim of this study was to compare the efficacy of shape-modified partially covered self-expandable metal stent (SEMS) that has enlarged head versus uncovered SEMS for palliation of gastric outlet obstruction (GOO). Methods A total of 48 patients underwent insertion of either enlarged-head SEMS (n = 24) or uncovered SEMS (uSEMS) (n = 24) for palliation of GOO from July 2009 to July 2016. Patients with inoperable or advanced malignancy were included. Technical feasibility and clinical outcomes were compared. Results Technical success rate was 100% (24/24) and 95.8% (23/24) for enlarged-head SEMS group and uSEMS group, respectively. Clinical success rate was 87.5% (21/24) and 87.0% (20/23) for enlarged-head SEMS group and uSEMS group, respectively. The gastric outlet obstruction scoring system score significantly improved in both groups (p < 0.001 for both). Mean survival was similar between the groups: enlarged-head SEMS group, 99.3 days (range, 19–358 days) versus uSEMS group, 82.1 days (range, 11–231 days) (p = 0.418). The mean stent patency also showed no difference between the groups: enlarged-head SEMS group, 87.1 days (range, 8–358 days) versus uSEMS group, 60.4 days (range, 2–231 days) (p = 0.204). With enlarged-head SEMS, distal migration did not occur, but proximal migration was observed in four cases. Conclusions Distal migration was prevented by shaping the SEMS to have an enlarged head, but improvement in stent patency could not be observed.

Abstract
BACKGROUND AND AIMS Uncovered self-expandable metal stents (U-SEMSs) and covered self-expandable metal stents (C-SEMSs) are available for palliative therapy for malignant gastric outlet obstruction (GOO). However, clinical differences and indications between the 2 types of SEMSs have not been elucidated. METHODS We retrospectively compared 126 patients with U-SEMS and 126 patients with C-SEMSs with regard to clinical outcome and factors predictive of clinical improvement after SEMSs placement. RESULTS No significant difference was observed between the U-SEMS and C-SEMS groups with respect to technical success, clinical success, GOO score, or time to stent dysfunction. Stent migration was significantly more frequent in patients with C-SEMSs (U-SEMSs, .79%; C-SEMSs, 8.73%; P = .005). Karnofsky performance status, chemotherapy, peritoneal dissemination, and stent expansion ≤ 30% were associated significantly with poor GOO score improvement in multivariable analyses, but stent type was not (P = .213). In subgroup analyses, insufficient (≤30%) stent expansion was an independent factor in patients with U-SEMSs (P = .041) but not C-SEMSs. In the insufficient stent expansion subgroup, C-SEMSs was associated significantly with superior clinical improvement compared with U-SEMSs (P = .01). Insufficient stent expansion was observed more frequently in patients with GI obstruction because of anastomotic sites or metastatic cancer (44.8% [13/29], P = .001). CONCLUSIONS No clinical difference, apart from stent migration, was observed between patients with U-SEMSs and C-SEMSs. GI obstruction because of an anastomotic site or metastatic cancer may be an indication for C-SEMS use to improve oral intake after SEMSs placement.

Abstract
PURPOSE To compare the outcomes of partially covered self-expandable metallic stent (SEMS) placement with surgical gastrojejunostomy (GJ) in patients with gastroduodenal obstruction caused by pancreatic cancer. METHODS The medical records of 107 patients with gastroduodenal obstruction caused by pancreatic cancer who underwent fluoroscopic partially covered SEMS placement (n = 75) or surgical GJ (n = 32) at our institution were reviewed. RESULTS The technical (100% vs. 100%; P > 0.999) and clinical (98.7% vs. 96.9%; P = 0.511) success rates were similar between the SEMS and GJ group. The mean gastric outlet obstruction scoring system score was higher in the SEMS group at 1 week after treatment (2.3 ± 0.5 vs. 1.2 ± 0.4; P < 0.001) but was similar between the two groups at 1 month (2.7 ± 0.5 vs. 2.8 ± 0.5; P = 0.242). The median hospital stay was shorter in the SEMS group than in the GJ group (7 vs. 14 days; P < 0.001). The overall complication (22.7% vs. 28.1%; P = 0.547) and reintervention (21.3% vs. 25.0%; P = 0.677) rates were similar between the two groups. The median patency (99 vs. 138 days; P = 0.102) and survival (106 vs. 140 days; P = 0.245) were also similar between the two groups. CONCLUSION The outcomes of partially covered SEMS placement seem to be more favorable than surgical GJ in patients with gastroduodenal obstruction caused by pancreatic cancer.

Abstract
BACKGROUND AND AIM Self-expandable metallic stents (SEMS) have been widely accepted as palliation therapy for malignant gastric outlet obstruction (GOO). However, the factors predictive of poor oral intake after SEMS placement have not been elucidated sufficiently. We aimed to clarify both the patient and stent-related predictive factors. METHODS We retrospectively reviewed 126 consecutive patients who underwent uncovered SEMS placement for malignant GOO between April 2010 and March 2013 at a university hospital and two tertiary care referral centers. RESULTS Technical success of SEMS placement was achieved in all 126 (100%) patients. Improved oral intake was observed in 111 (88.1%) patients. A Karnofsky performance status ≤ 40 (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.02-1.28; P = 0.041), peritoneal dissemination (OR, 1.20; 95% CI, 1.01-1.26; P = 0.038), and under-expansion of the SEMS on the procedure day (OR, 1.55; 95% CI, 1.26-1.62; P < 0.001) were independent predictive factors for poor improvement on the GOO scoring system, according to multivariate analysis. CONCLUSIONS SEMS under-expansion was a stent related, while poor performance status and peritoneal dissemination were patient related, predictive factors for poor oral intake after SEMS placement for malignant GOO.

Abstract
Upper gastrointestinal (GI) stents are increasingly being used to manage upper GI obstructions. Initially developed for palliative treatment of esophageal cancer, upper GI stents now play an emerging role in benign strictures of the upper GI tract. Because recurrent obstruction and stent-related complications are common, new modifications of stents have been implemented. Self-expandable metal stents (SEMS) have replaced older plastic stents. In addition, newly designed SEMS have been developed to prevent complications. This review provides an overview of the various types, indications, methods, complications, and clinical outcomes of upper GI stents in a number of malignant and benign disorders dividing the esophagus and gastroduodenum.

Abstract
Herein, we report a case of early in-stent occlusion due to the ingrowth of soft oedematous mucosal tissue through the lattices of an uncovered stent, which was used for palliation of a postoperative gastrojejunal anastomotic stricture. The in-stent occulsion was treated with the deployment of a second stent, which was covered, within the first stent. This led to successful resolution of the occlusion.

Abstract
BACKGROUND The use of endoluminal stents has been proposed for the management of fistulas and anastomotic strictures after bariatric surgery. The objective of our study was to determine the success of endoscopically placed, self-expandable metal stents (SEMS) in bariatric patients specifically with either chronic persistent anastomotic or staple line leaks/fistulas or chronic, persistent anastomotic strictures. METHODS We treated 21 patients including 5 with chronic staple line leaks/fistulas (4 from the gastric sleeve after biliopancreatic diversion with duodenal switch [BPD/DS] and 1 after removal of an eroding laparoscopic adjustable gastric band) and 16 with chronic anastomotic strictures (15 at the gastrojejunostomy after Roux-en-Y gastric bypass and 1 at the duodenoileal anastomosis after BPD/DS). Patients with early leaks or anastomotic strictures were excluded. RESULTS All but one of these patients had been referred to our institution after chronic treatment elsewhere was unsuccessful with prior stent placement for fistulas or multiple endoscopic dilations for strictures. Their bariatric operations had been performed a mean of 386 days beforehand. Stent placement was performed successfully in all patients without complications but was successful in only 4 of 21 patients (19%)-2 with chronic fistulas and 2 with chronic anastomotic strictures. Stent migration occurred in 10 patients (47%); the migrated stents were removed/replaced endoscopically in 7 patients but required elective operative removal in 3 with concomitant correction of the leak, fistula, or anastomotic stricture; none were operated emergently. CONCLUSION Only 4 of 21 patients with a chronic persistent leak or anastomotic stricture were treated definitively using a SEMS. Although endoluminal stents may not lead to resolution of a chronic leak or stricture, SEMS may suppress ongoing sepsis and allow patients to undergo nutritional resuscitation orally before operative correction.

A systematic review and meta-analysis of randomized trials and prospective studies comparing covered and bare self-expandable metal stents for the treatment of malignant obstruction in the digestive tract. Int J Med Sci 2013; 10:825-35. [PMID: 23794946 PMCID: PMC3689879 DOI: 10.7150/ijms.5969] [Citation(s) in RCA: 51] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2013] [Accepted: 04/16/2013] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Self-expandable metal stents (SEMS) are widely used for the palliative treatment of malignant gastrointestinal obstruction. Our aim was to evaluate the evidence comparing covered and bare SEMS in the digestive tract using meta-analytical techniques. METHODS A literature search was performed using PubMed, Cochrane Library, and Embase databases for comparative studies assessing the two types of stents. The primary outcomes of interest were stent patency and patient survival; second outcomes included technical success, clinical success, tumor ingrowth, tumor overgrowth, and stent migration. A random-effects model was conducted. Pooled analysis was done separately based on the different segments of the digestive tract. RESULTS Eleven studies (8 randomized controlled trials and 3 prospective cohort studies) including a total of 1376 patients were identified. Covered SEMS were equivalent to bare SEMS in terms of technical success, clinical success, stent patency (gastroduodenal obstruction: HR =0.87, 95% CI 0.53-1.42; colorectal obstruction: HR =0.89, 95% CI 0.18-4.45; biliary obstruction: HR =0.73, 95% CI 0.41-1.32) and survival rates (esophageal obstruction: HR =1.80, 95% CI 0.73-4.44; gastroduodenal obstruction: HR =0.83, 95% CI 0.55-1.26; biliary obstruction: HR =0.99, 95% CI 0.77-1.28), although bare stents were more prone to tumor ingrowth (esophageal obstruction: RR =0.10, 95% CI 0.01-0.77; gastroduodenal obstruction: RR =0.12, 95% CI 0.03-0.55; colorectal obstruction: RR =0.21, 95% CI 0.06-0.70; biliary obstruction: RR =0.21, 95% CI 0.06-0.69), whereas covered stents had the higher risk of stent migration (gastroduodenal obstruction: RR =5.01, 95% CI 1.53-16.43; colorectal obstruction: RR =11.70, 95% CI 2.84-48.27; biliary obstruction: RR =8.11, 95% CI 1.47-44.76) and tumor overgrowth (biliary obstruction: RR =2.03, 95% CI 1.08-3.78). CONCLUSION Both covered and bare SEMS are comparable in efficacy for the palliative treatment of malignant obstruction in the digestive tract. Each type of the stents has its own merit and demerit relatively.

Abstract
AIM: To evaluate the results of duodenal stenting for palliation of gastroduodenal malignant obstruction by using a gastric outlet obstruction score (GOOS).
METHODS: A prospective, non-randomized study was performed at a tertiary center between August 2005 and April 2010. Patients were eligible if they had malignant gastric outlet obstruction (GOO) and were not candidates for surgical treatment. Medical history and patient demographics were collected at baseline. Scheduled interviews were made on the day of the procedure and 15, 30, 90 and 180 d later or unscheduled as necessary.
RESULTS: Fifteen patients (6 male, 9 female; median age 61 years) with GOO who had undergone duodenal stenting were evaluated. Ten patients had metastasis at baseline (66.6%) and 14 were unable to accept oral intake (93.33%), including 7 patients who were using a feeding tube. Laboratory data showed biliary obstruction in eight cases (53.33%); all were submitted to biliary drainage. Two patients developed obstructive symptoms due to tumor ingrowth after 30 d and another due to tumor overgrowth after 180 d. Two cases of stent migration occurred. A good response to treatment was observed, with a mean time of approximately 1 d (19 h) until toleration of a liquid diet and slightly more than 2 d for both soft solids (51 h) and a solid food/normal diet (55 h). The mean time to first failure to maintain liquid intake (GOOS ≥ 1) was 93 d. During follow-up, the mean time to first failure to maintain the previously achieved GOOS of 2-3 (solid/semi-solid food), considered technical failure, was 71 d. On the basis of oral intake a GOOS is defined: 0 for no oral intake; 1 for liquids only; 2 for soft solids only; 3 for low-residue or full diet.
CONCLUSION: Enteral stenting to alleviate gastroduodenal malignant obstruction improves quality of life in patients with limited life expectancy, which can be evaluated by using a GOO scoring system.

Duodenal and colonic stent placement with 0.025″ and 0.035″ guidewires is equally safe and effective. Dig Dis Sci 2012; 57:726-31. [PMID: 21984440 DOI: 10.1007/s10620-011-1932-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2011] [Accepted: 09/20/2011] [Indexed: 12/11/2022]
Abstract
BACKGROUND The overwhelming majority of reported duodenal and colonic SEMS placements in the literature have used the 0.035″ guidewire almost to the exclusion of guidewires of other diameters. AIMS The purpose of this study was to compare technical and clinical outcomes in patients undergoing duodenal or colonic SEMS placement with 0.025″ or 0.035″ guidewires. METHODS This was a retrospective study to compare technical and clinical outcomes and complications of patients receiving duodenal or colonic SEMS placement with a 0.035″ guidewire to those undergoing placement with a 0.025″ guidewire. RESULTS A total of 34 duodenal and 30 colonic stent placement procedures were performed in 59 patients. Technical success was achieved in all duodenal stent placement procedures. The difference in mean GOOSS score increase after stent placement was not statistically significant between the 0.035″ and 0.025″ guidewire groups (P = 0.49). Complications were not statistically significantly different between the two groups undergoing gastroduodenal stenting. Technical and clinical success was achieved in all colonic stent placement procedures. There were no statistically significant differences in complication rates between the two groups undergoing colonic stenting. Procedure times were not significantly different using either wire type. CONCLUSIONS Our study shows that both 0.035″ and 0.025″ guidewires were equally effective with regards to technical success, clinical success, and with regards to the development of complications.

Abstract
OBJECTIVE The objective of our study was to assess the incidence, predictive factors, and treatment of tumor overgrowth after placement of expandable metallic dual stents in patients with malignant gastroduodenal obstruction. MATERIALS AND METHODS Expandable metallic dual stents were inserted under fluoroscopic guidance in 583 patients with symptomatic malignant gastroduodenal obstruction. We retrospectively reviewed prospectively collected patient records to determine the incidence and treatment of tumor overgrowth after stent placement and used multivariate analysis to determine factors predicting tumor overgrowth. RESULTS Tumor overgrowth occurred after stent placement in 22 of 583 patients (3.8%) (range, 41-634 days; mean, 179.0 days). Duodenal lesions (odds ratio [OR], 4.505; p = 0.002), longer survival time (OR, 1.003; p = 0.001), and length of obstruction (OR, 0.783; p = 0.035) were independent predictors of tumor overgrowth. Twenty of the 22 patients were successfully treated by placement of a second dual stent, whereas the other two patients refused placement of a second stent or other further treatment. Overall, 19 of 20 patients (95%) showed improvement in symptoms after second stent placement. Duodenal perforation occurred in one of the 20 patients 125 days after placement of a second stent and was treated surgically. CONCLUSION Tumor overgrowth seems to be an uncommon complication of expandable metallic dual stent placement in patients with malignant gastroduodenal obstruction. Tumor overgrowth is associated with duodenal lesions, longer survival time, and shorter stricture length. Tumor overgrowth can be successfully managed by coaxial insertion of a second dual-expandable metallic stent into the obstructed first stent.

Abstract
BACKGROUND A self-expandable metal stent (SEMS) has emerged as an effective palliative treatment for malignant gastroduodenal obstruction resulting from gastric or periampullary malignancy. Despite the stent's effectiveness, tumor ingrowth and stent migration remain complications requiring reintervention. The purpose of this study was to evaluate the efficacy and safety of a double-layered SEMS (Comvi). METHODS We performed a prospective multicenter study in two university hospitals and two referral hospitals. In fifty consecutive patients with malignant gastroduodenal obstructions, placement of double-layered SEMS, comprising an outer uncovered stent and an inner covered stent that overlap each other, was performed. Palliation, efficacy, and incidence of complications were evaluated. RESULTS Technical and clinical success was achieved in 100 and 88% of patients, respectively. There were no procedure-related complications. Five patients experienced stent migration (10%). For four of five patients' stent migration occurred within two weeks of stent placement. Stent collapse occurred in five patients after one month. Reintervention for stent migration, collapse, or tumor overgrowth was required for 14 (28%) patients. CONCLUSIONS Endoscopic placement of a double-layered stent is a safe and effective modality for the palliation of malignant gastroduodenal obstruction. However, considering reintervention, this stent does not seem to add any clear advantage compared with preexisting uncovered stents. Migration, especially within the first two weeks, and stent collapse are still unresolved problems. The device should be fixed or the design modified to reduce these problems.

Abstract
Malignant gastric outlet obstruction (GOO) is a commonly encountered entity, defined as the inability of the stomach to empty because of mechanical obstruction at the level of either the stomach or the proximal small bowel. In this article, current literature on GOO is reviewed with a focus on enteral stents to include symptoms and diagnosis, stent and nonstent treatment, types of enteral stents, indications and contraindications to stent placement, and technical and clinical success rates. In comparison with gastrojejunostomy, enteral stent placement is better suited for patients with a shorter life expectancy and/or those who are poor surgical candidates.

Abstract
BACKGROUND AND AIM Recurrent stent obstruction necessitating reintervention is problematic and incompletely understood. The aim of the present study was to identify factor(s) predisposing to reintervention. METHODS Retrospective review of patients (n = 117) referred to a single major endoscopic referral centre for palliative enteral stenting from 1999 to 2006. Twelve were excluded due to inadequate follow-up data (n = 7) or initial radiographic documentation (n = 5). A total of 105 patients (gastroduodenal n = 57, colonic n = 48) were therefore analyzed. The primary outcome of interest was recurrent obstruction necessitating reintervention. Kaplan-Meier analysis of potential factors predisposing to reintervention, including stent angulation (mild [<15°], moderate [15°-90°], severe [>90°]) was completed for 98 patients (technically successful enteral stenting). RESULTS Technical and clinical success were achieved in 98 of 105 (93.3%) and 92 of 98 (93.9%) cases, respectively. Post-stenting median survival was 97.5 days (range 3-1054). Eighteen patients (18.4%) required reintervention for stent obstruction at a median time to reintervention of 85 days (range 7-481). Increased stent angulation (severe vs mild hazard ratio 6.73 (95% confidence interval 1.59-27.59), P = 0.009) was the only statistically significant factor in multivariate analysis predicting reintervention. CONCLUSIONS Despite its limitation as a retrospective review, this study found that reintervention for stent obstruction is necessary in almost one in five cases, and increasing severity of stent angulation is the most important risk factor.

Abstract
BACKGROUND Self-expandable metallic stents (SEMSs) provide effective palliation for inoperable malignant gastric outlet obstruction (GOO). The objective of this study was to evaluate the effectiveness of SEMSs in patients with recurrent gastric cancer after radical gastrectomy. METHODS We retrospectively analyzed data from patients with gastric cancer who underwent endoscopic SEMS placement. The patients had obstructive symptoms due to recurrent gastric cancer after curative-intent subtotal or total gastrectomies. Technical and clinical success rates of stent placement were evaluated and clinical outcomes were compared according to operation types. RESULTS A total of 15 patients underwent total gastrectomies with esophagojejunostomies and Roux-en-Y reconstructions, 8 underwent subtotal gastrectomies with Billroth I reconstructions, and 12 underwent subtotal gastrectomies with Billroth II reconstructions. Four patients in the Billroth II group received stents in afferent and efferent loops, so a total of 39 stents were placed. Technical success was achieved with 92% (36/39) of stents, and clinical success occurred with 90% (35/39) of stents, with no significant differences among surgery groups or between stent types (covered vs. uncovered). The GOO score (preprocedure: 0.45±0.62) increased by 1 week (2.06±0.51, p<0.001) and was maintained up to 1 month (1.71±1.15, p<0.001 compared with initial score). Complications occurred with 17 of 39 stents (44%) and included 2 perforations, 3 migrations, and 12 restenoses. Median stent patency duration was 10.7 weeks and median survival was 21.3 weeks; these did not significantly differ by surgery group (p=0.25 and 0.93, respectively) or stent type (covered vs. uncovered, p=0.51 and 0.96, respectively). CONCLUSION Endoscopic SEMS placement for obstruction due to recurrent cancer after total or subtotal gastrectomy is feasible and provides effective short-term palliation, independent of the type of surgical procedure or stent (covered vs. uncovered) used.

Abstract
Unresectable malignant gastric outlet obstruction (GOO) severely affects the quality of life, with complications that include nausea, vomiting, aspiration, pain, and malnutrition. Although palliative surgical procedures have been traditionally performed, they are associated with high morbidity and mortality rates. Placing self-expandable metallic stents is associated with higher clinical success rates, lower morbidity, shorter time from the procedure to starting oral intake, lower incidence of delayed gastric emptying, and a shorter hospital stay than palliative surgery. Fluoroscopic or endoscopic placement of either bare or covered self-expandable metallic stents is a safe, nonsurgical, palliative treatment option for unresectable malignant GOOs, with a high clinical success rate and a low rate of serious complications. Stent obstruction and migration are the most common complications, but most can be managed by interventional treatments. Although there have been substantial developments in stent design over the past decade, large prospective, randomized studies are required to determine the ideal stent for malignant GOOs.

Abstract
OBJECTIVE Placement of a self-expandable metal stent is a palliative treatment of choice for patients with malignant gastric outlet obstruction (GOO). Although covering an enteral stent with a membrane almost solves the problem of tumor ingrowth, stent migration continues to be a major unresolved problem. Our aim was to evaluate the clinical efficacy of endoscopic clipping for prevention of covered stent migration in the treatment of malignant GOO. MATERIAL AND METHODS A total of 25 consecutive patients with malignant GOO were evaluated prospectively. After deployment of a double-layered combination stent (comprising an outer uncovered stent and an inner covered stent), three endoscopic clips were applied for fixation of the proximal end of the enteral stent to the gastric or duodenal mucosa. RESULTS Technical and clinical success rates were 100% (25/25) and 88% (22/25), respectively. No stent migration was observed in any of the patients. Five patients (20%) experienced complications such as tumor overgrowth and stent compression. CONCLUSION Endoscopic clipping for enteral stent placement seems to be effective for prevention of covered stent migration in patients with malignant GOO.

Abstract
BACKGROUND The placement of self-expandable metallic stents (SEMS) is known to be effective palliative treatment of malignant gastroduodenal obstruction. There are two types of SEMS--covered and uncovered--each with its own advantages and disadvantages. This study was conducted to compare between the clinical outcomes of covered and uncovered stents in patients with malignant gastroduodenal obstruction. PATIENTS AND METHODS The study was conducted prospectively from January 1998 to June 2007 and 154 patients were included. All had symptomatic gastroduodenal obstruction and were not candidates for curative operation. Seventy patients received covered SEMS, while the other 84 received uncovered SEMS. We compared technical and clinical success rates, tumour ingrowth rate, stent migration rate, stent patency time and patient survival in both SEMS groups. RESULTS The technical and clinical success rates of the covered and uncovered stent groups did not differ. Stent migration was more frequent in the covered stent group than in the uncovered group (17.1% versus 0%; p=0.0001). Tumour ingrowth was more frequent in the uncovered stent group than in the covered group (16.6% versus 2.9%; p=0.0066). Stent re-intervention rate, stent patency time and patient survival did not differ between groups. CONCLUSION Covered and uncovered stent insertions are technically feasible and effective palliative treatment of malignant gastroduodenal obstruction. Covered stents can reduce the risk of tumour ingrowth, whereas uncovered stents are effective in preventing stent migration. However, covered stents did not differ from uncovered stents in regard to other clinical outcomes.

Abstract
Gastric outlet obstruction is a well- recognized complication of locally advanced carcinoma of the head of the pancreas. The authors report a transoral placement of a duodenal stent over a percutaneous guide wire, inserted retrogradely through a transhepatic approach via the ampulla of Vater, in a patient in whom traditional stent placement was technically not possible. This technique allows safe duodenal stent placement for different malignant gastric outlet obstruction such as pancreatic, gastric, duodenal, and metastases to the peripancreatic region.

Abstract
AIM: To examine the technical feasibility and clinical outcomes of the endoscopic insertion of a self-expandable metal stent (SEMS) for the palliation of a malignant anastomotic stricture caused by recurrent gastric cancer.
METHODS: The medical records of patients, who had obstructive symptoms caused by a malignant anastomotic stricture after gastric surgery and underwent endoscopic insertion of a SEMS from January 2001 to December 2007 at Kangnam St Mary’s Hospital, were reviewed retrospectively.
RESULTS: Twenty patients (15 male, mean age 63 years) were included. The operations were a total gastrectomy with esophagojejunostomy (n = 12), subtotal gastrectomy with Billroth-I reconstruction (n = 2) and subtotal gastrectomy with Billroth-II reconstruction (n = 8). The technical and clinical success rates were 100% and 70%, respectively. A small bowel or colon stricture was the reason for a lack of improvement in symptoms in 4 patients. Two of these patients showed improvement in symptoms after another stent was placed. Stent reobstruction caused by tumor ingrowth or overgrowth occurred in 3 patients (15%) within 1 mo after stenting. Stent migration occurred with a covered stent in 3 patients who underwent a subtotal gastrectomy with Billroth-II reconstruction. Two cases of partial stent migration were easily treated with a second stent or stent repositioning. The median stent patency was 56 d (range, 5-439 d). The median survival was 83 d (range, 12-439 d).
CONCLUSION: Endoscopic insertion of a SEMS provides safe and effective palliation of a recurrent anastomotic stricture caused by gastric cancer. A meticulous evaluation of the presence of other strictures before inserting the stent is essential for symptom improvement.

Abstract
OBJECTIVE The objective of our study was to compare the clinical effectiveness of metallic stent placement for relief of gastric outlet obstruction caused by gastric carcinoma and pancreatic carcinoma. MATERIALS AND METHODS A total of 207 patients with gastric outlet obstruction caused by inoperable gastric carcinoma (n = 147) or pancreatic carcinoma (n = 60) underwent metallic stent placement. RESULTS Technical success of metallic stent placement was achieved in all patients. Clinical success was achieved in 97% and 93% of patients with gastric and pancreatic carcinoma, respectively (p = 0.286). The overall complication rate did not differ significantly between the gastric (29%) and pancreatic (23%) carcinoma groups (p = 0.441). Stent collapse was significantly more frequent in the gastric carcinoma group (11%) than the pancreatic carcinoma group (2%) (p = 0.027), whereas serious complications, including gastrointestinal bleeding and intestinal perforation, occurred more frequently in the pancreatic (7%) than the gastric (1%) carcinoma group (p = 0.026). The cumulative survival period was significantly longer in the gastric carcinoma (median, 153 days) than the pancreatic carcinoma (median, 90 days) group (p = 0.041), but cumulative stent patency did not differ significantly between the gastric carcinoma (median, 350 days) and pancreatic carcinoma (median, 385 days) groups (p = 0.415). CONCLUSION Metallic stent placement was clinically effective in the palliative treatment of gastric outlet obstruction in patients with gastric and pancreatic carcinoma. The two groups differed significantly in the rates of stent collapse and serious complications and patient survival after stent placement.

Abstract
Background Malignant gastric outlet obstruction (GOO) is commonly seen in patients with advanced gastric-, pancreatic-, duodenal, hepatobiliary or metastatic malignancies. Ten to 25% of patients with pancreatic cancer will develop duodenal obstruction during the course of the disease. Duodenal stenting with self-expandable metal stents is an alternative treatment to surgical bypass procedures. Our aim was to review the published literature regarding treatment of malignant GOO with stents to reveal whether the information provided is sufficient to evaluate the clinical effects of this treatment Methods A literature search from 2000 – 2007 was conducted in Pub Med, Embase, and Cochrane library, combining the following search terms: duodenal stent, malignant duodenal obstruction, gastric outlet obstruction, SEMS, and gastroenteroanastomosis. All publications presenting data with ≥ 15 patients and only articles written in English were included and a review focusing on the following parameters were conducted: 1) The use of graded scoring systems evaluating clinical success; 2) Assessment of Quality of life (QoL) before and after treatment; 3) Information on stent-patency; 4) The use of objective criteria to evaluate the stent effect. Results 41 original papers in English were found; no RCT's. 16 out of 41 studies used some sort of graded scoring system. No studies had objectively evaluated QoL before or after stent treatment, using standardized QoL-questionnaires, 32/41 studies reported on stent patency and 9/41 performed an oral contrast examination after stent placement. Objective quantitative tests of gastric emptying had not been performed. Conclusion Available reports do not provide sufficient relevant information of the clinical outcome of duodenal stenting. In future studies, these relevant issues should be addressed to allow improved evaluation of the effect of stent treatment.

Abstract
BACKGROUND Self-expandable metallic stents (SEMSs) are widely used for palliation of malignant gastric outlet obstruction (GOO). A common complication of their use, however, is stent obstruction caused by tumor ingrowth or hyperplasia. The covered SEMS was designed to prevent these problems. OBJECTIVE We compared the performance of uncovered and covered SEMSs in patients with GOO. DESIGN A retrospective study, single center. SETTING A tertiary-referral center. PATIENTS Sixty patients with symptomatic malignant GOO. INTERVENTIONS All patients received an uncovered or covered knitted nitinol stent by using the over-the-wire placement procedure. MAIN OUTCOME MEASUREMENT Comparison of the clinical outcome, complications, and the reintervention rate between uncovered and covered stents. RESULTS Thirty-one patients (mean [+/-SEM] age 72.2 +/- 2.1 years; 16 men) received uncovered SEMSs, and 29 (mean [+/-SEM] age 70.6 +/- 1.7 years; 17 men) received covered SEMSs. The technical success rate was 100% in both groups. No difference in clinical success was seen (90.3% uncovered group vs 86.2% covered group). Regarding early complications (<1 week), one mild case of pancreatitis from the stent covering the papilla occurred in each group. Late complications included reobstruction, migration, bleeding, stent fracture, and perforation. The occurrence of reobstruction did not differ between the 2 groups (3.2% uncovered group vs 10.3% covered group). No difference in migration (0% uncovered group vs 6.9% covered group) was seen. The uncovered group required less frequent reinterventions for stent reobstruction, migration, or stent fracture (3.2% uncovered group vs 20.7% covered group, P = .0490). The uncovered group had 2 major late complications: bleeding and perforation. All 60 patients died, with a median survival time of 51 days and 62 days, respectively. LIMITATIONS Small-sized, single-center, retrospective study. CONCLUSIONS In palliation for malignant GOO, covered stents were associated with a more frequent need for reintervention than uncovered stents, despite similar outcomes and complications. These results require confirmation in a larger randomized comparison.

Abstract
BACKGROUND Although endoscopic stent placement is now generally accepted as a palliative treatment for gastric outlet obstruction resulting from gastric cancer, it carries potential limitations such as tumor ingrowth or migration. OBJECTIVE Our purpose was to evaluate the technical and clinical efficacy of endoscopic placement of a newly designed double-layered combination pyloric stent. DESIGN Prospective, uncontrolled, single-center. SETTING Tertiary referral university hospital. PATIENTS Eleven patients with gastric outlet obstruction by unresectable stomach cancer. INTERVENTIONS Eleven patients received a double-layered combination pyloric stent (an outer uncovered stent to reduce migration and an inner polytetrafluoroethylene-covered stent to prevent tumor ingrowth). MAIN OUTCOME MEASUREMENT To evaluate technical success, clinical success, and complications, especially tumor ingrowth and migration. RESULTS Technical success was achieved in 11 of 11 (100%) patients. Among 11 patients in whom endoscopic stenting was placed successfully, clinical success was 90.9%, tumor ingrowth 0%, migration 9.1%, and tumor overgrowth 9.1%. Median stent patency period was 121 days. LIMITATIONS Small number of patients, uncontrolled study, short-term follow-up period. CONCLUSIONS We have described a technique for endoscopic metal stent placement by using the newly designed double-layered combination stent for gastric outlet obstruction by stomach cancer. This stent seems to be effective and looks promising for technical efficacy, clinical outcome, and preventing tumor ingrowth and migration.
