Abstract
Malignant gastric outlet obstruction (MGOO) is a clinical condition characterized by the mechanical obstruction of the pylorus or the duodenum due to tumor compression/infiltration, with consequent reduction or impossibility of an adequate oral intake. MGOO is mainly secondary to advanced pancreatic or gastric cancers, and significantly impacts on patients' survival and quality of life. Patients suffering from this condition often present with intractable vomiting and severe malnutrition, which further compromise therapeutic chances. Currently, palliative strategies are based primarily on surgical gastrojejunostomy and endoscopic enteral stenting with self-expanding metal stents. Several studies have shown that surgical approach has the advantage of a more durable relief of symptoms and the need of fewer re-interventions, at the cost of higher procedure-related risks and longer hospital stay. On the other hand, enteral stenting provides rapid clinical improvement, but have the limit of higher stent dysfunction rate due to tumor ingrowth and a subsequent need of frequent re-interventions. Recently, a third way has come from interventional endoscopic ultrasound, through the development of endoscopic ultrasound-guided gastroenterostomy technique with lumen-apposing metal stent. This new technique may ideally encompass the minimal invasiveness of an endoscopic procedure and the long-lasting effect of the surgical gastrojejunostomy, and brought encouraging results so far, even if prospective comparative trial are still lacking. In this Review, we described technical aspects and clinical outcomes of the above-cited therapeutic approaches, and discussed the open questions about the current management of MGOO.

[PMID: 29760541 PMCID: PMC5949711 DOI: 10.3748/wjg.v24.i18.1978] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2018] [Revised: 04/26/2018] [Accepted: 05/06/2018] [Indexed: 02/06/2023] Open
Abstract
The major symptoms of advanced hepatopancreatic-biliary cancer are biliary obstruction, pain and gastric outlet obstruction (GOO). For obstructive jaundice, surgical treatment should de consider in recurrent stent complications. The role of surgery for pain relief is marginal nowadays. On the last, there is no consensus for treatment of malignant GOO. Endoscopic duodenal stents are associated with shorter length of stay and faster relief to oral intake with more recurrent symptoms. Surgical gastrojejunostomy shows better long-term results and lower re-intervention rates, but there are limited data about laparoscopic approach. We performed a systematic review of the literature, according PRISMA guidelines, to search for articles on laparoscopic gastrojejunostomy for malignant GOO treatment. We also report our personal series, from 2009 to 2017. A review of the literature suggests that there is no standardized surgical technique either standardized outcomes to report. Most of the studies are case series, so level of evidence is low. Decision-making must consider medical condition, nutritional status, quality of life and life expectancy. Evaluation of the patient and multidisciplinary expertise are required to select appropriate approach. Given the limited studies and the difficulty to perform prospective controlled trials, no study can answer all the complexities of malignant GOO and more outcome data is needed.

Abstract
Purpose To compare the outcome between laparoscopic gastrojejunostomy (LapGJ) and duodenal stenting (DS) in terms of oral intake, nutritional status, patency duration, effect on chemotherapy and survival. Methods Medical records of 115 patients, who had LapGJ or duodenal stent placement between July 2005 and September 2015 in Seoul National University Bundang Hospital, have been reviewed retrospectively. Oral intake was measured with Gastric Outlet Obstruction Scoring System. Serum albumin and body weight was measured as indicators of nutritional status. The duration of patency was measured until the date of reintervention. Chemotherapy effect was calculated after the procedures. Survival period and oral intake was analyzed by propensity score matching age, sex, T-stage, comorbidities, and chemotherapy status. Results Forty-three LapGJ patients and 58 DS patients were enrolled. Improvement in oral intake was shown in LapGJ group versus DS group (88% vs. 59%, P = 0.011). Serum albumin showed slight but significant increase after LapGJ (+0.75 mg/dL vs. −0.15 mg/dL, P = 0.002); however, there was no difference in their body weight (+5.1 kg vs. −1.0 kg, P = 0.670). Patients tolerated chemotherapy longer without dosage reduction after LapGJ (243 days vs. 74 days, P = 0.006) and maintained the entire chemotherapy regimen after the procedure longer in LapGJ group (247 days vs. 137 days, P = 0.042). LapGJ showed significantly longer survival than DS (220 vs. 114 days, P = 0.004). Conclusion DS can provide faster symptom relief but LapGJ can provide improved oral intake, better compliance to chemotherapy, and longer survival. Therefore, LapGJ should be the first choice in gastric outlet obstruction patients for long-term and better quality of life.

Abstract
The use of stents in the gastrointestinal tract has been subjected to major changes. Initially, the use of stents was restricted to malignant strictures in patients with metastatic disease. But thanks to reduction of the morbidity and mortality rates, they are now used with curative intention and in patients with benign diseases after careful selection. However, for patients presenting with colon obstruction due to an advanced colon carcinoma, the mortality and morbidity are still high. The purpose of this review is to provide an overview of indications, techniques and further developments of the stents in the gastrointestinal tract and to highlight the predominant role of multidetector row computed tomography (MDCT) in the detection of potential complications.

Abstract
BACKGROUND A conformable self-expandable metallic stent was developed to overcome the limitation of previous self-expandable metallic stents. The aim of this study was to evaluate outcomes after placement of conformable covered and uncovered self-expandable metallic stents for palliation of malignant gastroduodenal obstruction. METHODS A single-blind, randomized, parallel-group, prospective study were conducted in 4 medical centres between March 2009 and July 2012. 134 patients with unresectable malignant gastroduodenal obstruction were assigned to a covered double-layered (n=66) or uncovered unfixed-cell braided (n=68) stent placement group. Primary analysis was performed to compare re-intervention rates between two groups. RESULTS 120 patients were analysed (59 in the covered group and 61 in the uncovered group). Overall rates of re-intervention were not significantly different between the two groups: 13/59 (22.0%) in the covered group vs. 13/61 (21.3%) in the uncovered group, p=0.999. Stent migration was more frequent in the covered group than in the uncovered group (p=0.003). The tumour ingrowth rate was higher in the uncovered group than in the covered group (p=0.016). CONCLUSIONS The rates of re-intervention did not significantly differ between the two stents. Conformable covered double-layered and uncovered unfixed-cell braided stents were associated with different patterns of stent malfunction.

Abstract
BACKGROUND The use of various kinds of metal stents has emerged as an effective palliative treatment for malignant gastric outlet obstruction (GOO). However, most of these metal stents were designed for use in the esophagus or intestine and have a high incidence of stent obstruction and stent migration when used elsewhere. OBJECTIVE To evaluate the efficacy and safety of individualized stents (designed according to the shape and size of the GOO) in order to determine whether such stents could reduce the incidence of stent obstruction and migration. DESIGN Multicenter, prospective, clinical trial. SETTING Two tertiary-care referral centers. PATIENTS Thirty-seven patients who presented with symptomatic unresectable malignant GOO caused by distal gastric cancer between April 2005 and June 2009. INTERVENTION Placement of the individualized metal stents. MAIN OUTCOME MEASUREMENTS The primary endpoint was to optimize stent resolution of proximal obstruction as determined by a GOO scoring system. Secondary endpoints were success rates, survival rates, and adverse events. RESULTS Technical and clinical success was achieved in 97.3% and 94.4% of patients, respectively. The rate of resolution of proximal obstruction by a proximal stent was 97.3%. There were no procedure-related perforations or deaths. No stent migration or obstruction by tumor growth were found. The mean survival time was 232 days (range 28-387 days). LIMITATIONS A single-arm study in tertiary-care centers. CONCLUSION Placement of individualized stents is a safe and effective modality for the palliation of malignant GOO caused by distal stomach cancer and can help reduce tumor ingrowth and stent migration.

Abstract
PURPOSE To evaluate the technical feasibility and safety of overtube-guided covered metallic stent placement as palliative treatment for patients with inoperable malignant gastric outlet obstructions. METHODS To relieve the symptoms of severe nausea and recurrent vomiting in five patients with inoperable gastric cancer, we used an overtube (Long overtube; Sumitomo Bakelite, Tokyo, Japan) to place large-diameter, self-expandable, covered esophageal Ultraflex stents (inner diameter 22-28 mm, length 10 or 12 cm; Boston Scientific, Watertown, MA, USA). Success was defined both technically and clinically. RESULTS The stent placement was technically successful in all patients and resulted in improvement of symptoms in all five patients, four of whom were thereafter able to ingest solid food. The remaining patient, a 94-year-old man, was unable to ingest food because of dysmasesis. During the mean follow-up of 17 weeks, there was no stent reocclusion and no life-threatening complications developed. CONCLUSIONS The placement of a large diameter, self-expandable, covered esophageal stent using an overtube appears to be effective for the palliative treatment of malignant gastric outlet obstruction.

Abstract
INTRODUCTION Endoscopic stenting (ES) is a minimally invasive alternative to surgical gastroenterostomy (GE) for palliation of malignant gastroduodenal obstructions. This consecutive, retrospective analysis compares the clinical outcome of all patients undergoing ES or GE in the same period. METHODS ES was performed at the Endoscopy Department, University Hospital Mannheim or at the Interdisciplinary Endoscopy Department, University Hospital Hamburg-Eppendorf. GE was performed at the Surgical Department, University Hospital Mannheim. All palliative ES or GE on patients with malignant gastroduodenal obstruction without earlier gastric resections between January 2001 and April 2007 were evaluated. Main outcome measurements were ability of solid food intake (gastric outlet obstruction score), persistence of nausea and vomiting (gut function score), length of hospital stay, morbidity, mortality and re-interventions. RESULTS A total of 44 ES and 43 GE were performed. Nausea and vomiting--measured by means of the gut function score--persisted in significantly more patients in the GE group than in those who underwent stent placement (p = 0.0102). The gastric outlet obstruction score at discharge from the hospital revealed no significant difference in the ability of solid food intake between the groups. The hospital stay was significantly longer in the GE group (p = 0.0003). There was no significant difference in mortality and the rates of complications and re-interventions. CONCLUSION In this study, ES is a generally equivalent--and in several points superior--alternative to GE for palliation of malignant gastroduodenal obstruction. ES seems to be the less invasive alternative for symptomatic patients. GE has good results in patients with longer survival and can be practiced within abdominal explorations.

Abstract
BACKGROUND AND AIMS Malignant gastric outlet obstruction can be treated by means of enteral stenting or surgical gastrojejunalanatomosis. We evaluated in a prospective and multicentre study the efficacy of the enteral stent on food intake, the quality of life impact, and the relationship between efficacy and determined clinical and technical parameters. PATIENTS AND METHODS Seventy one patients affected by symptoms arising from gastroduodenal obstruction due to malignant tumors, with criteria of irresecability, metastatic disease or very high surgical risk, were treated by means of self expanding metal stents. We used the GOOSS index to evaluate efficacy, and the Euro Qol-5D index to evaluate quality of life. RESULTS Before stenting patients with GOOSS 0 and 1 were 68 (98.5%). After stenting patients with GOOSS 2 and 3 (semisolid and solid food) were 58 (84,1%) (P<.0001). The Euro Qol-5D index measured before and a month after stenting were 10.17 and 10.04 respectively (P=.6). The median survival was 91 days (9-552). The enteral stents for localised tumors in the duodenum and the gastrojejunalanastomosis were effective in 26 patients (70.2%) and 13 patients respectively (86.6%), while the enteral stents of tumors in the antrum were effective in only 5 patients (29.4%). CONCLUSIONS The palliative treatment of malignant gastric outlet obstruction with a uncovered metal stent produces a significant improvement of oral food intake and maintains the overall quality of life index. The antral localization is associated with a lower efficacy of the procedure.

Abstract
AIM: To find out whether a newly designed big cup nitinol stent is suitable for treatment of patients with gastric outlet obstruction resulting from gastric cancer.
METHODS: The new stent is composed of a proximal big cup segment (20 mm in length and 48-55 mm in diameter), a middle part (60 mm in length and 20 mm in diameter) covered by a polyethylene membrane and a distal sphericity (20 mm in length and 28 mm in diameter). Half of the proximal big cup segment is also covered by a polyethlene membrane, which is adjacent to the middle part of the stent. The stent is preloaded in a 6.0-mm-diameter introducer system. Thirteen patients with gastric outlet obstruction resulting from gastric cancer received the new stents under endoscopic and fluoroscopic guidance.
RESULTS: Technical success was achieved in 12 of 13 (92.3%) patients. Among the 12 patients in whom endoscopic stent was placed successfully, the clinical success rate was 91.7% during a follow-up of average 6.5 mo. During the first month follow-up, the migration rate was 0%, recurrent obstruction 0% and gastric bleeding 8.3%. During the follow-up between 2-12 mo, no migration, recurrent obstruction and gastric bleeding occurred.
CONCLUSION: The proximal big cup segment seems to be effective and promising for technical efficacy, clinical outcome, and preventing migration and tumor ingrowth and increasing the emptying rate of sinus ventriculi.

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
Malignant gastroduodenal obstruction can occur in up to 20% of patients with primary pancreatic, gastric or duodenal carcinomas. Presenting symptoms include nausea, vomiting, abdominal distention, pain and decreased oral intake which can lead to dehydration, malnutrition, and poor quality of life. Endoscopic stent placement has become the primary therapeutic modality because it is safe, minimally invasive, and a cost-effective option for palliation. Stents can be successfully deployed in the majority of patients. Stent placement appears to lead to a shorter time to symptomatic improvement, shorter time to resumption of an oral diet, and shorter hospital stays as compared with surgical options. Recurrence of the obstructive symptoms resulting from stent occlusion, due to tumor ingrowth or overgrowth, can be successfully treated with repeat endoscopic stent placement in the majority of the cases. Both endoscopic stenting and surgical bypass are considered palliative treatments and, to date, no improvement in survival with either modality has been demonstrated. A tailored therapeutic approach, taking into consideration patient preferences and involving a multidisciplinary team including the therapeutic endoscopist, surgeon, medical oncologist, radiation therapist, and interventional radiologist, should be considered in all cases.

Abstract
Many patients with malignant gastroduodenal obstruction have an unresectable primary lesion and distant metastases, which may prompt palliative management to allow the patient to eat and to improve the quality of life. Intraluminal metallic stent implantation (MSI) under fluoroscopic guidance has been reported to be an effective option for symptomatic relief in these patients, with a good safety record. An alternative, dual interventional therapy (DIT), has been used during the last decade, in which prosthesis insertion is followed by intra-arterial chemotherapy via the tumor-feeding arteries. The aim of this study was to compare success rates, complication rates, and survival time between MSI and DIT in patients who presented with gastroduodenal obstruction from advanced upper gastrointestinal tract cancer. All consecutive patients with malignant gastroduodenal obstruction seen at our center between October 2002 and August 2007 were retrospectively studied. Patients were treated palliatively by either MSI or DIT by the patient's or the next of kin's decision. Outcomes included technical and clinical success, complication rates, and survival. Of the 164 patients with malignant gastric and duodenal outlet obstructions, 80 (49%) underwent stent insertion as the primary therapy, while the remaining 84 (51%) received DIT. Clinical characteristics were similar between the two groups. In the MSI cohort initial stent implantation was successful in 73 patients (91%), two stents were used in 5 patients, and delayed additional stent insertion for stent obstruction related to tumor overgrowth was required in 3 patients during follow-up. In the DIT cohort the technical success rate was 94%, 3 patients required two stents, and stent obstruction occurred in 2 patients after initial stent placement. Early postprocedural clinical success, indicated by average dysphagia score, improved significantly in both groups: MSI group, from 4.56 to 1.51 (P < 0.01); and DIT group, from 4.38 to 1.48 (p < 0.01). There were no short-term complications. Late complications including hematemesis (n = 3), migration (n = 12), and stent occlusion due to tumor overgrowth (n = 5) were evenly distributed between the groups. In the DIT group chemotherapy-induced neutropenia and transient renal dysfunction were detected in six patients, which improved after symptomatic management. Mean survival time after the procedure was 5.9 and 11.1 months for MSI and DIT, respectively (P < 0.001). In conclusion, both MSI and DIT offer effective palliation for malignant gastroduodenal obstruction, but DIT appears to offer superior survival over MSI alone. Ideally, a prospective randomized trial comparing these two techniques should be carried out to validate this result.

Abstract
BACKGROUND Gastric outlet obstruction (GOO) is most commonly a complication of advanced distal gastric, periampullary, or duodenal malignancy. Palliation of obstruction is the primary aim of treatment in most of these patients. Self-expandable metal stents have emerged as an effective treatment option. OBJECTIVE Our purpose was to investigate the efficacy and safety of a newly developed enteral metal stent (WallFlex). DESIGN Prospective multicenter cohort study. SETTING Three tertiary referral centers (2 academic). PATIENTS Fifty-one consecutive patients with symptomatic malignant GOO from January 2005 to February 2006. INTERVENTION Placement of a self-expandable metallic stent (WallFlex). MAIN OUTCOME MEASUREMENTS The primary end point was defined as improvement of the GOO scoring system for the remainder of the patients' lives. Secondary end points focused on efficacy and safety and global quality of life. RESULTS The Gastric Outlet Obstruction Scoring System score improved (P < .001), the body mass index decreased (P < .001), and the World Health Organization performance score improved (P = .002) when the score before stenting was compared with the mean score until death. Global quality of life did not improve. Technical and clinical success was achieved in 98% and 84% of the patients. Median survival was 62 days (75% alive at 35 days, 25% alive at 156 days). Median stent patency was 307 days (75% functional at 135 days, 25% functional at 470 days). Stent dysfunction was proved in 7 patients (14%), migration in 1 (2%), and tumor overgrowth or ingrowth in 6 (12%). LIMITATIONS Lack of a control group. CONCLUSION Placement of a WallFlex enteral stent in patients with nonresectable malignant GOO is safe and provides a statistically significant and clinically relevant relief of obstructive symptoms with a low need for reintervention.

Abstract
BACKGROUND AND AIM The aim of the present study was to investigate the clinical effectiveness, safety, and outcome associated with the use of covered expandable Nitinol stents (Taewoong Medical, Seoul, Korea) for the treatment of malignant gastroduodenal obstructions. METHODS Between March 2001 and October 2004, covered expandable Nitinol stents were placed in 68 consecutive patients under endoscopic and fluoroscopic guidance for the following reasons: gastric carcinoma (n = 49), recurrent carcinoma after partial gastrectomy (n = 7), or another malignant neoplasm involving the duodenum (n = 12). RESULTS Technical success was achieved in 60 of the 68 patients (88.2%). After stent placement, mean dysphagia score improved from a mean of 3.5 to 1.2 (P < 0.001). The mean period of primary stent patency was 107.2 days. During follow up (mean 4.4 months; range, 1-15 months), major complications (migration [6], bleeding [3], perforation [1], ingrowth [1], overgrowth [7], fistula [1]) occurred in 19 patients (27.9%), and stent migration occurred in six (8.8%) (proximal migration into the stomach [n = 3], or distal migration [n = 3]). Recurrent dysphagia (mainly due to tumor ingrowth/overgrowth) occurred in eight patients (11.8%). CONCLUSION Covered expandable Nitinol stents appear to offer an effective and feasible palliative therapy in patients with a malignant gastroduodenal obstruction.

Abstract
AIM: To investigate the clinical efficacy and technique skills of metallic stent placement for malignant gastric outlet obstruction.
METHODS: Nine advanced gastric cancer patients with obstruction of digestive tract were included in this study, and 2 methods were adopted. The first, stents were placed under endoscope by straight sight (stent pusher: 140 mm in length and 4-6 mm in diameter). The second, duodenal stents were placed under endoscope by straight sight via biopsy channel (3.2 or 4.2 mm in diameter).
RESULTS: All the patients received stent placement successful at the first try. Among the patients, 3 received stents of 2 cm×10 cm, and 6 received stents of 2 cm×8 cm. Pylorus stents, duodenal stents, and esophageal stents were placed in 2 cases, 6 cases and 1 case, respectively. The first method was used in 7 cases, while the second was used in 2 cases. Stents were expanded about 90% under X-ray 24-48 h after operation, and the patients could take in liquid food 24 h after operation. The common complications included nausea, vomiting, upper digestive tract hemorrhage and upper abdominal pain, etc. Obstructive jaundice was found in 1 case. After 3-mo following up, no stent migration, breaking off and obstruction occurred. Of the 9 cases, 3 survived 10-15 d and 2 survived 1-2 mo. The rest 5 cases had survived 3 mo. The mean unimpeded time was 53.4 d.
CONCLUSION: Technique skills should be stressed when metallic stent placement is used in the treatment of malignant gastric outlet obstruction. The efficacy of metallic stent placement depends on the location of metallic stents and disease indications.

Abstract
BACKGROUND Stent placement in the distal duodenum or proximal jejunum with a therapeutic gastroscope can be difficult, because of the reach of the endoscope, loop formation in the stomach, and flexibility of the gastroscope. The use of a colonoscope may overcome these problems. OBJECTIVE To report our experience with distal duodenal stent placement in 16 patients using a colonoscope. METHODS Multicenter, retrospective series of patients with a malignant obstruction at the level of the distal duodenum and proximal jejunum and treated by stent placement using a colonoscope. Main outcome measurements are technical success, ability to eat, complications, and survival. RESULTS Stent placement was technically feasible in 93% (15/16) of patients. Food intake improved from a median gastric outlet obstruction scoring system (GOOSS) score of 1 (no oral intake) to 3 (soft solids) (p = 0.001). Severe complications were not observed. One patient had persistent obstructive symptoms presumably due to motility problems. Recurrent obstructive symptoms were caused by tissue/tumor ingrowth through the stent mesh [n = 6 (38%)] and stent occlusion by debris [n = 1 (6%)]. Reinterventions included additional stent placement [n = 5 (31%)], gastrojejunostomy [n = 2 (12%)], and endoscopic stent cleansing [n = 1 (6%)]. Median survival was 153 days. CONCLUSION Duodenal stent placement can effectively and safely be performed using a colonoscope in patients with an obstruction at the level of the distal duodenum or proximal jejunum. A colonoscope has the advantage that it is long enough and offers good endoscopic stiffness, which avoids looping in the stomach.

Abstract
PURPOSE To assess the technical feasibility and clinical effectiveness of placement of expandable metallic stents in patients with recurrent cancer after a gastrojejunostomy. MATERIALS AND METHODS Data from 39 consecutive patients who had undergone metallic stent placement for recurrent malignant obstruction after a gastrojejunostomy were retrospectively analyzed. Thirty patients underwent a distal gastrectomy with a gastrojejunostomy with (n=10) or without (n=20) jejunojejunostomy, two patients underwent distal gastrectomy with a Roux-en-Y gastrojejunostomy, and seven patients underwent a palliative gastrojejunostomy with (n=5) or without (n=2) jejunojejunostomy. A total of 57 metallic stents were used in this study: four bare stents, 29 partially covered stents, and 24 fully covered stents. Types of obstruction were classified into 12 patterns and types of stent placement were classified into 16 patterns. RESULTS Stent placement was technically successful in all patients. After stent placement, 35 of the 39 patients (90%) experienced improvement of their symptoms, two showed no change, and the remaining two showed aggravation of symptoms as a result of faulty stent placement. Two patients treated with stent placement only in the afferent loop died of aspiration pneumonia. In one of two patients who underwent stent placement according to pattern 6, afferent loop syndrome occurred 10 days after stent placement and was treated by percutaneous pigtail catheter drainage. Stent migration occurred in four of 24 fully covered stents, but in none of the bare or partially covered stents. Tumor ingrowth occurred in one of four bare stents, tumor overgrowth in one of 29 partially covered stents, and mucosal prolapse in one of 24 fully covered stents; all were treated with a second stent placement. CONCLUSIONS Placement of expandable metallic stents in patients with recurrent cancer after a gastrojejunostomy seems to be feasible and effective, but accurate knowledge of the type of surgical procedure performed and determination of the pattern of tumor recurrence are important for successful stent placement.

Abstract
AIM Gastrojejunostomy (GJJ) and duodenal stent placement are the most commonly used palliative treatment modalities for gastric outlet obstruction (GOO). In this retrospective study, we compared GJJ and stent placement with regard to medical effects. METHODS Medical records of 95 patients who had undergone palliative treatment between 1994 and 2006 in a Dutch university hospital, were reviewed. Study outcomes were improvement of food intake, complications, persistent and recurrent symptoms, re-interventions, hospital stay, and survival. RESULTS Fifty-three patients were referred for duodenal stent placement and 42 patients underwent GJJ. There were no differences in technical and clinical success and the incidence of minor and early major complications and survival. Food intake improved more rapidly after stent placement than GJJ (P = 0.01). The time to late major complications, recurrent obstructive symptoms and re-intervention was significantly shorter after stent placement than GJJ (P = 0.004, 0.002, and 0.004, respectively). Hospital stay was also shorter after stent placement than GJJ (P < 0.001). CONCLUSION These findings suggest that stent placement is associated with better short-term outcomes and GJJ with better long-term outcomes. A large randomized controlled trial is however needed to systematically compare stent placement with GJJ with regard to medical effects, quality of life and costs.

Abstract
BACKGROUND Gastrojejunostomy (GJJ) is the most commonly used palliative treatment modality for malignant gastric outlet obstruction. Recently, stent placement has been introduced as an alternative treatment. We reviewed the available literature on stent placement and GJJ for gastric outlet obstruction, with regard to medical effects and costs. METHODS A systematic review of the literature was performed by searching PubMed for the period January 1996 and January 2006. A total of 44 publications on GJJ and stents was identified and reported results on medical effects and costs were pooled and evaluated. Results from randomized and comparative studies were used for calculating odds ratios (OR) to compare differences between the two treatment modalities. RESULTS In 2 randomized trials, stent placement was compared with GJJ (with 27 and 18 patients in each trial). In 6 comparative studies, stent placement was compared with GJJ. Thirty-six series evaluated either stent placement or GJJ. A total of 1046 patients received a duodenal stent and 297 patients underwent GJJ. No differences between stent placement and gastrojejunostomy were found in technical success (96% vs. 100%), early and late major complications 7% vs. 6% and 18% vs. 17%, respectively) and persisting symptoms (8% vs. 9%). Initial clinical success was higher after stent placement (89% vs. 72%). Minor complications were less frequently seen after stent placement in the patient series (9% vs. 33%), however the pooled analysis showed no differences (OR: 0.75, p = 0.8). Recurrent obstructive symptoms were more common after stent placement (18% vs. 1%). Hospital stay was prolonged after GJJ compared to stent placement (13 days vs. 7 days). The mean survival was 105 days after stent placement and 164 days after GJJ. CONCLUSION These results suggest that stent placement may be associated with more favorable results in patients with a relatively short life expectancy, while GJJ is preferable in patients with a more prolonged prognosis. The paucity of evidence from large randomized trials may however have influenced the results and therefore a trial of sufficient size is needed to determine which palliative treatment modality is optimal in (sub)groups of patients with malignant gastric outlet obstruction.

Abstract
BACKGROUND Uncovered, rather than covered, metal stents are commonly used for palliation of malignant gastric outlet obstruction because of the low risk of stent migration, but tumor ingrowth risk is a major drawback. Few reports address malignant obstruction after gastric surgery. OBJECTIVE Our purpose was to compare the technical feasibility and clinical outcome of using an endoscopic uncovered self-expandable metal stent (SEMS) and simultaneous use of uncovered and covered SEMS (double SEMS) in patients with recurrent malignant obstruction after gastric surgery. DESIGN Retrospective study. SETTING Tertiary care, academic medical center, from August 2000 to June 2005. PATIENTS Twenty patients were included in the study. All patients had symptomatic obstruction with nausea, vomiting, and decreased oral intake. INTERVENTION Ten patients received uncovered SEMS; the other 10 received double SEMS. MAIN OUTCOME MEASUREMENTS To compare tumor ingrowth and stent patency between the uncovered and the double-SEMS groups. RESULTS Technical and clinical successes were 10 of 10 and 8 of 10, respectively, in the uncovered SEMS group and 10 of 10 and 10 of 10, respectively, in the double SEMS group. Six of 10 patients (60%) with uncovered SEMS had tumor ingrowth compared with 1 of 10 patients with double SEMS, P = .057. Five of 10 patients (50%) with uncovered SEMS had very early restenosis, but no patients had early restenosis in the double SEMS group, P = .033. Stent patency was a median of 21.5 days (range, 7-217 days) in the uncovered SEMS group and 150 days (range 29-263 days) in the double SEMS group, P = .037. Survival duration was 109.5 days (range 29-280 days) and 150 days (range 29-263 days), respectively. LIMITATIONS This was a small retrospective study. CONCLUSION Simultaneous double stent placement seems to be technically feasible and effective for palliative treatment of recurrent malignant obstruction after gastric surgery. Double stent placement is important in preventing tumor ingrowth, especially very early restenosis, and prolongs stent patency. We suggest that this procedure be considered rather than uncovered stent alone as the primary choice for palliation of obstruction in such patients.

Abstract
AIM: To ascertain clinical outcome and complications of self-expandable metal stents for endoscopic palliation of patients with malignant obstruction of the gastrointestinal (GI) tract.
METHODS: A retrospective review was performed throughout August 2000 to June 2005 of 53 patients with gastric outlet obstruction caused by stomach cancer. All patients had symptomatic obstruction including nausea, vomiting, and decreased oral intake. All received self-expandable metallic stents.
RESULTS: Stent implantation was successful in all 53 (100%) patients. Relief of obstructive symptoms was achieved in 43 (81.1%) patients. No immediate stent-related complications were noted. Seventeen patients had recurrent obstruction (tumor ingrowth in 14 patients, tumor overgrowth in 1 patient, and partial distal stent migration in 2 patients). The mean survival was 145 d. Median stent patency time was 187 d.
CONCLUSION: Endoscopic placement of self-expandable metallic stents is a safe and effective treatment for the palliation of patients with inoperable malignant gastric outlet obstruction caused by stomach cancer.

Abstract
AIM: To compare two techniques of endoscopic metal stent placement in the treatment of gastric outlet obstruction (GOO) and evaluate their clinical efficacies.
METHODS: A total of 28 GOO patients were randomly allocated into 2 groups for endoscopic metal stent placement. Metal stents were placed under endoscope in 18 cases (group A), and they were placed into 10 cases (group B) through large aperture for biopsy. The clinical efficacy, complications and followed-up results were compared between the two groups.
RESULTS: The success rates of stent placement were 88.9% and 100%, respectively, in the two groups, and the overall success rate was as high as 94.4%. The effective rates for abdominal distention and vomiting were 81.3% and 87.5%, respectively. No obvious complications occurred in short term in all the patients except for 1 case of cardiac arrhythmia in group A. After following-up for 1 to 42 months, GOO reoccurred in 5 cases, and the average time for the reoccurrence was 110 days. The mean survival time was 140 days. Most patients mainly died of tumor progression.
CONCLUSION: Both techniques of endoscopic metal stent placement are safe and effective in the treatment of GOO, while metal stent placement via large aperture for biopsy is superior to the other.

Abstract
BACKGROUND We have previously reported the feasibility and the safety of an endoscopic transgastric approach to the peritoneal cavity in a porcine model. We now report successful performance of endoscopic gastrojejunostomy with survival. METHODS All procedures were performed on 50-kg pigs, with the pigs under general anesthesia, in aseptic conditions with sterilized endoscopes and accessories. The stomach was irrigated with antibiotic solution, and a gastric incision was performed with a needle-knife and a sphincterotome. A standard upper endoscope was advanced through a sterile overtube into the peritoneal cavity. A loop of jejunum was identified, was retracted into the stomach, and was secured with sutures while using a prototype endoscopic suturing device. An incision was made into the jejunal loop with a needle-knife, and the filet-opened ends of the jejunal wall were secured to the gastric wall with a second line of sutures, completing the gastrojejunostomy. OBSERVATIONS Two pigs survived for 2 weeks. Endoscopy and a radiographic contrast study performed after gastrojejunostomy revealed a patent anastomosis with normal-appearing gastric and jejunal mucosa. Postmortem examination demonstrated a well-healed anastomosis without infection or adhesions. CONCLUSIONS The endoscopic transgastric approach to create a gastrojejunostomy is technically feasible and can be performed, with survival, in a porcine model.

Abstract
PURPOSE To investigate the technical feasibility and clinical effectiveness of a dual expandable nitinol stent in the palliative treatment of malignant gastroduodenal strictures. MATERIALS AND METHODS The dual stent consisted of two stents, an outer partially covered stent and an inner bare nitinol stent. The outer diameter of the stent delivery system was 3.8 mm. With fluoroscopic guidance, the outer stent was placed into the stricture, followed by coaxial placement of the inner stent. The stent placement was attempted in 102 consecutive patients with malignant gastroduodenal strictures. The underlying causes of malignant strictures were gastric cancer (n = 55), pancreatic cancer (n = 24), gallbladder cancer (n = 7), cholangiocarcinoma (n = 5), duodenal cancer (n = 5), and metastatic cancer (n = 6). All patients presented with symptoms of gastric outlet obstruction. RESULTS Stent placement was technically successful and well tolerated in 101 of 102 patients (99%). After stent placement, 85 of the 101 patients (84%) with technical success experienced improvement of their symptoms. Tumor overgrowth occurred in five patients, stent migration in two, mucosal hyperplasia in one, bleeding in one, and jaundice in two. Seventy one of the 101 patients died 5 to 340 days (mean, 71 days) after stent placement from progression of their disease, myocardial infarction, bleeding, or sepsis. The remaining 30 patients are still alive 6 to 227 days (mean, 39 days) after stent placement. The 30-day, 60-day, 90-day, and 180-day survival rates were 78%, 58%, 39%, and 8%, respectively. CONCLUSION The dual stent with a 3.8-mm stent delivery system is easy to insert, safe, and reasonably effective for the palliative treatment of malignant gastroduodenal strictures.

Abstract
Enteral strictures are a frequent indication for surgery in Crohn's disease. Postoperative complications are increased in patients with poor preoperative nutritional status, which is common in this patient population. We present a 49-year-old female with longstanding Crohn's disease admitted to our Digestive Health Center with four weeks of increasing abdominal symptoms and radiographic evidence of small-bowel obstruction caused by ileal stricture. Given her poor nutritional status, our team elected to pursue metallic enteral stenting as a bridge to surgical resection. Two Wallstents were placed; luminal patency was subsequently confirmed by a fluoroscopic study. The patient tolerated regular diet and was discharged. When seen in follow-up, she remained asymptomatic and wished to defer surgical intervention indefinitely.

Abstract
BACKGROUND The treatment of gastroduodenal outflow obstruction (GOO) caused by malignant diseases represents a significant challenge. Open surgical gastrojejunostomy (GJ) has been the treatment of choice, but it has high morbidity and mortality rates. More recently, endoscopic placement of self-expanding metallic stents (SEMS) has been proposed and the results of small, preliminary studies are encouraging. This study compared technical and clinical success, morbidity, mortality, and hospital stay in patients undergoing endoscopic and surgical treatment of GOO. METHODS Medical records of 60 consecutive patients with GOO seen between April 1997 and November 2002 were retrospectively reviewed. Because of extremely short life expectancy, 13 patients were treated by insertion of a double-lumen nasogastric-jejunal tube. The remaining 47 patients (28 men, 19 women; mean age 73.5 years, range 48-92 years) with unresectable pancreatic (33), gastric (7), metastatic lymph nodal (4), papillary (2), and biliary (1) tumors were treated by placement of a SEMS (24) or open surgical GJ (23). RESULTS The technical success rates were similar, but clinical success was lower in the GJ group (92% vs. 56%, p = 0.0067). The SEMS group had a shorter length of hospital stay (3.0 [1.4] days vs. 24.1 [10.3], p < 0.001). Thirty-day mortality was 30% in the GJ group, and 0% in the SEMS group ( p = 0.004). Morbidity was higher in the GJ compared with the SEMS group (61% vs. 17%, p = 0.0021). Mean survival was longer in the SEMS group (96.1 [9.6] days vs. 70.2 [36.2] days, p = 0.0165 for a single test of hypothesis; Bonferroni correction for a multiple testing removes this significance), consequently, out-of-hospital survival was longer for the SEMS group (93.2 [9.3] days vs. 46.0 [31.5] days, p < 0.001). None of the endoscopic procedures required the assistance of an anesthesiologist or the use of an operating room. CONCLUSIONS The results of this retrospective study suggest that SEMS insertion is better than surgical GJ for palliation of patients with GOO in terms of clinical success, morbidity, and mortality. Technical success rates were similar. SEMS placement should be proposed as the first-line treatment for relief of GOO. However, a randomized, comparative, prospective study of SEMS vs. laparoscopic GJ is needed.

Abstract
BACKGROUND The management of gastric outlet obstruction with expandable metallic stents is difficult and frequently is associated with late complications. A new, flexible, covered metal stent has been developed, which may be suitable for treatment of patients with recurrent malignant strictures after gastric surgery. METHODS The stainless-steel stent is covered by a polyethylene membrane. It has a proximal funnel attached to an expanded antimigratory segment 29 mm in diameter. The flexible covering membrane connects isolated distal segments that are 20 mm in diameter. The stent is preloaded in a 6.7-mm-diameter introducer system. The structural features and the increased flexibility of this new prosthesis are intended to reduce the risk of migration and the frequency of late complications, and to broaden the range of applications. RESULTS This stent was used to successfully treat two patients with recurrent tortuous malignant strictures after partial or complete gastrectomy. CONCLUSIONS This new flexible, polyethylene-covered stent potentially is a new alternative for the palliation of patients with recurrent, inoperable gastric malignant strictures.

Abstract
Gastroduodenal obstruction is a preterminal event in patients with advanced malignancies of the stomach, pancreas, and duodenum. It severely limits the quality of life in affected patients due to constant emesis and associated malnutrition. Surgical gastrojejunostomy has been the traditional palliative treatment but is associated with a high complication rate, and delayed gastric emptying is a frequent problem. Gastroduodenal stent placement is a very safe and effective palliation method in patients with unresectable malignant tumors causing gastric outlet obstruction, with adequate palliation obtained in most cases. The procedure can be performed under fluoroscopic guidance or with a combination of fluoroscopic and endoscopic techniques. Advantages of gastroduodenal stent placement over surgical palliation include suitability as an outpatient procedure, more rapid gastric emptying, greater cost effectiveness, fewer complications, and improved quality of life. Covered duodenal stents are currently being evaluated and may play an increasingly important role in preventing recurrent obstruction secondary to tumor ingrowth. Moreover, simultaneous palliation of biliary and duodenal malignant strictures is possible with the use of metallic stents. Gastroduodenal stent placement is a promising new alternative for the palliation of malignant gastroduodenal obstruction.

Abstract
Up to 20 per cent of patients with pancreatic cancer develop gastric outlet obstruction. Traditionally, these patients have been managed with an open gastrojejunostomy. Laparoscopic gastrojejunostomy may now be a preferable approach. We conducted a retrospective review of nine patients who underwent laparoscopic gastrojejunostomy in 2001–2004. All nine patients had unresectable pancreatic cancer. There were six men and three women. Median age was 66 years (range 36–87). Two patients had prior laparotomies for attempted resection. Four patients had previously placed duodenal stents that failed. Four others had undergone unsuccessful attempts of duodenal stenting. Median operating time was 116 minutes (range 75–300). There were no intraoperative complications or conversions to open procedure. Median time to postoperative oral intake was 4 days (range 3–6), and median postoperative length of stay was 7 days (range 5–18). Eight of our nine patients were palliated successfully using this technique. There were no complications or deaths related to the operation. All patients were discharged from the hospital. Six patients have since died, with a median postoperative survival of 2.5 months (range 1.5–8). Laparoscopic gastrojejunostomy provides safe and effective palliation of gastric outlet obstruction in patients with unresectable pancreatic cancer. This approach allows for rapid palliation in a group of patients with a very limited survival.

Abstract
BACKGROUND The purpose of this study was to investigate the technical feasibility and the clinical effectiveness of the placement of covered self-expandable metallic stents for the treatment of anastomotic obstructions in recurrent gastric carcinoma. METHODS With fluoroscopic guidance, covered stents were placed in 25 patients with recurrent gastric carcinoma for the palliation of obstructions at anastomotic sites (14 gastrojejunostomy, 11 esophagojejunostomy). All patients had severe nausea and recurrent vomiting before the stent placement. RESULTS Stent placement was technically successful in 24 patients (96%). After stent placement, symptoms improved in all 24 patients. During the follow-up of 2 to 65 weeks (mean, 13.7 weeks), stent migration occurred in 1 patient 16 days after the procedure. He needed percutaneous catheter drainage because of an abscess, which was followed by esophagojejunostomy site rupture during a second stent trial. Stricture recurred in 4 patients because of tumor overgrowth 10 to 55 weeks after the procedure; all patients underwent coaxial placement of a second stent and had good oral intake. CONCLUSIONS The placement of covered expandable metallic stents seems to be both technically feasible and an effective means for the palliation of anastomotic obstructions in recurrent gastric carcinoma. This procedure can be considered to be the primary choice for the palliation in those patients.

Abstract
This update is devoted to discussion of optimal supportive and palliative care of patients with pancreatic cancer. Approximately 33,000 new cases of pancreatic cancer are predicted for the U.S. in 2002. Because diagnosis and intervention occur late in the course of this disease, the vast majority of patients already have metastatic disease at the time of diagnosis. These tumors are relatively resistant to systemic chemotherapy, making pancreatic cancer the fourth leading cause of cancer-related death in the U.S. and the Western world. For these reasons, efforts at identifying and treating disease-related symptomatology are priorities. This update overviews symptom management, supportive care strategies, and both standard and emerging palliative chemotherapy options. The incorporation of molecularly targeted therapies into treatment of metastatic pancreatic cancer is reviewed as well. These strategies are of relevance to internists, gastroenterologists, oncologists, and other specialists who care for patients with pancreatic cancer.

Abstract
OBJECTIVE To test the hypothesis that laparoscopic staging improves outcome in patients with peripancreatic carcinoma compared to standard radiology staging. SUMMARY BACKGROUND DATA Diagnostic laparoscopy of peripancreatic malignancies has been reported to improve assessment of tumor stage and to prevent unnecessary exploratory laparotomies in 10% to 76% of patients. METHODS Laparoscopy and laparoscopic ultrasound were performed in 297 consecutive patients with peripancreatic carcinoma scheduled for surgery after radiologic staging. Patients with pathology-proven unresectable tumors were randomly allocated to either surgical or endoscopic palliation. All others underwent laparotomy. RESULTS Laparoscopic staging detected biopsy-proven unresectable disease in 39 patients (13%). At laparotomy, unresectable disease was found in another 72 patients, leading to a detection rate for laparoscopic staging of 35%. In total, 145 of the 197 patients classified as having "possibly resectable" disease after laparoscopic staging underwent resection (74%). Average survival in the group of 14 patients with biopsy-proven unresectable tumors randomly allocated to endoscopic palliation was 116 days, with a mean hospital-free survival of 94 days. The corresponding figures were 192 days and 164 days in the 13 patients allocated to surgical palliation. CONCLUSIONS Because of the limited detection rate for unresectable metastatic disease and the likely absence of a large gain after switching from surgical to endoscopic palliation, laparoscopic staging should not be performed routinely in patients with peripancreatic carcinoma.

Abstract
Stents represent an exciting development in the field of gastroenterology. Their use to maintain luminal patency in the pancreatobiliary system has been well established. Stents have also found a place in maintaining the patency of the esophagus. Recent developments have led to an increasing role for their use to decompress both the small and large intestine. In the small intestine they are often placed to palliate proximal obstruction in the duodenum or the very proximal jejunum resulting from various malignancies. Self-expandable metal stents are an attractive alternative to surgery, especially in patients with compromised performance status, and can be done safely as outpatient procedures. However, one should be aware of the associated risks and complications. With a proper understanding of the principles involved in stent placement one can safely undertake this procedure.

Abstract
Esophageal and gastric malignancies are common worldwide. Less than half are amenable to curative treatment at the time of diagnosis because of advanced or metastatic disease. Palliation is often required for symptoms, such as dysphagia, gastrointestinal bleeding, aspiration caused by tracheoesophageal fistula, nausea and emesis secondary to gastric outlet obstruction, and malnutrition. This article reviews the gastric outlet obstruction, and malnutrition. This article reviews the medical, endoscopic, and surgical options for palliative treatment.

Abstract
OBJECTIVE The purpose of this study was to investigate the technical feasibility and the clinical effectiveness of fluoroscopically guided placement of covered self-expandable metallic stents in the treatment of malignant antroduodenal obstructions. SUBJECTS AND METHODS With fluoroscopic guidance, covered self-expandable metallic stents were placed in 18 consecutive patients with inoperable malignant antroduodenal obstructions. All patients were treated for severe nausea and recurrent vomiting. RESULTS Stent placement was technically successful in all patients with or without gastrostomy (n = 2) and balloon dilatation (n = 3). After stent placement, symptoms improved in all but one patient, who had another stenosis in the proximal jejunum. During the follow-up of 2-73 weeks (mean, 12 weeks), stent migration occurred in three patients (16.7%) from 1 to 41 days after the procedure. These patients were treated successfully by means of placing a second covered metallic stent. Two patients, who were followed up for longer than 30 weeks, showed a recurrence of strictures because of mechanical failure of the stents; one of the patients was treated with coaxial placement of a second covered metallic stent, which had a positive clinical outcome. CONCLUSION Fluoroscopically guided placement of covered self-expandable metallic stents is technically feasible and effective for the palliative treatment of inoperable malignant antroduodenal obstructions. The rate of stent migration in our study was lower than those in previous reports.

Abstract
PURPOSE To assess whether coaxial placement of uncovered and covered expandable nitinol stents overcomes the disadvantages of the increased migration rate seen with covered stents and the tumor ingrowth seen in uncovered stents in the treatment of malignant gastric outlet obstructions. MATERIALS AND METHODS Two types of expandable nitinol stent were designed: an uncovered stent and a covered stent. Under fluoroscopic guidance, the uncovered and covered stents were placed coaxially with complete overlap in 39 consecutive patients with malignant gastric outlet obstruction caused by stomach cancer. Food intake capacity was graded on a scale of 0-4. Stent patency rate was estimated by the Kaplan-Meier method. RESULTS Technical success rate was 97% (38 of 39 patients). After stent placement, food intake capacity improved at least one grade in 36 patients. Stent migration occurred in three patients (8%), that is, partial (n = 2) or complete (n = 1) upward migration of the inner covered stent into the stomach. Two of these patients were treated by placement of an additional covered stent. During the mean follow-up period of 134 days (range, 15-569 d), 10 patients developed recurrent symptoms of obstruction with tumor overgrowth being the most common cause. Nine underwent placement of an additional covered stent with good results. The median period of primary stent patency was 157 days (mean, 278 d). The 30-, 60-, and 180-day patency rates were 97%, 91%, and 39%, respectively. Four patients (10%) died within 1 month after the procedure. CONCLUSION Coaxial stent placement technique seems to contribute to decreasing the migration rate of the stent and decrease the rate of recurrent obstruction by preventing or delaying tumor ingrowth.

Abstract
Pancreatic cancer is most frequently a fatal disease with many associated morbidities. Clinicians skilled in its treatment are adept at management of symptoms caused by local and systemic effects of the malignancy. Patients should be assured that there are many treatments that can be used aggressively to maintain their comfort and independence for as long as possible. Patients should be encouraged to inform their health care providers of any discomfort or medical or psychological problems they are experiencing. At times, referrals to specialists can be beneficial for consideration of specific symptom-improving interventions. Timely referral to a palliative medicine service and hospice can have significant beneficial impact on the total care of the patient and on home caregiver.

Abstract
OBJECTIVE Malignant gastric outlet obstruction is seen in the setting of a variety of cancers, most commonly pancreatic. Self-expanding metal stents can be used to palliate these patients and restore the ability to eat. METHODS We reviewed the Mayo Clinic experience in the endoscopic treatment of malignant gastric outlet obstruction. Thirty-six patients (26 male, 10 female) were treated between October, 1998 and January, 2001. Data were collected from charts, endoscopy reports, x-rays, and telephone calls. A scoring system was created to grade the ability to eat. RESULTS All procedures were successful. Thirty-one of 36 patients (86%) required one stent at initial endoscopy, and 5/36 patients (14%) required two or more stents. Pretreatment, 19/36 patients (53%) were nil per os, 15/36 (42%) drank liquids, and 2/36 were able to eat soft solids. After stent placement, only 1/36 (3%) was still nil per os, 13/36 (36%) drank liquids, 13/36 (36%) ate soft solids, and 9/36 (25%) ate a full diet. The improvement in ability to eat using the scoring system was statistically significant (p < 0.0001). Nine of 36 patients (25%) required reintervention for recurrent symptoms. Sixteen of 36 patients (44%) had concomitant or subsequent development of biliary obstruction, of which 15 were successfully decompressed. CONCLUSIONS Self-expanding metal stents are a safe and efficacious method for palliating malignant gastric outlet obstruction. The majority of patients do not require reintervention, and those that do can usually be managed nonoperatively.
