Abstract
Malignant gastric outlet obstruction (GOO) is a condition characterized by blockage or narrowing where the stomach empties its contents into the small intestine due to primary malignant tumors or metastatic diseases. This condition leads to various symptoms such as nausea, vomiting, abdominal pain, and weight loss. To manage malignant GOO, different treatment options have been employed, including surgical gastrojejunostomy (SGJ), gastroduodenal stenting (GDS) using self-expandable metallic stent (SEMS), and endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ). This review focuses on comparing the clinical outcomes of endoscopic stenting (GDS and EUS-GJ) with SGJ for malignant GOO. Studies have shown that GDS with SEMS provides comparable clinical outcomes and safety for the palliation of obstructive symptoms. The choice between covered and uncovered SEMS remains controversial, as different studies have reported varying results. EUS-GJ, performed via endoscopic ultrasound guidance, has shown promising efficacy and safety in managing malignant GOO, but further studies are needed to establish it as the primary treatment option. Comparative analyses suggest that GDS has higher recurrence and reintervention rates compared to EUS-GJ and SGJ, with similar overall procedural complications. However, bleeding rates were lower with GDS than with SGJ. Randomized controlled trials are required to determine the optimal treatment approach for malignant GOO.

Abstract
BACKGROUND To develop and validate a risk score for predicting clinical success after duodenal stenting using self-expanding metallic stents (SEMS) for malignant gastric outlet obstruction (GOO). RESEARCH DESIGN AND METHODS Consecutive patients who underwent duodenal stenting for malignant GOO were evaluated. Potential predictors of clinical success were determined by uni/multivariate logistic regression analysis.Multiplication of the regression coefficients of the logistic regression model by a factor of two and rounding to obtain easy-to-use point numbers enabling the calculation of the score. Using 10-fold cross-validation, the model was internally validated. RESULTS One hundred twelve patients were included. Clinical success was achieved in 93 (83.0%) patients. On multivariate logistic regression, selected age ≤65 years (p = 0.05, 1.5 points), stenosis type I (p = 0.04, 3 points), and pancreatic cancer (p = 0.01, 3.5 points) were significant predictors of clinical success. On the Receiver Operating Characteristic (ROC) analysis, a score of 5 had higher specificity and sensitivity. CONCLUSION Our score could be useful at identifying, among poor surgical candidates, patients more likely to benefit from SEMS.

Abstract
Pancreatic cancer is the leading cause of cancer-related morbidity and mortality with an overall five-year survival of less than 9% in the United States. At presentation, the majority of patients have painless jaundice, pruritis, and malaise, a triad that develops secondary to obstruction, which often occurs late in the course of the disease process. The technical advancements in radiological imaging and endoscopic interventions have played a crucial role in the diagnosis, staging, and management of patients with pancreatic cancer. Endoscopic retrograde cholangiopancreatography (ERCP)-guided diagnosis (with brush cytology, serial pancreatic juice aspiration cytologic examination technique, or biliary biopsy) and therapeutic interventions such as pancreatobiliary decompression, intraductal and relief of gastric outlet obstruction play a pivotal role in the management of advanced pancreatic cancer and are increasingly used due to improved morbidity and complication rates compared to surgical management. In this review, we highlight various ERCP-guided diagnostic and therapeutic interventions for the management of pancreatic cancer.

JGH OPEN 2018; 3:65-70. [PMID: 30834343 PMCID: PMC6386745 DOI: 10.1002/jgh3.12110] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Revised: 09/20/2018] [Accepted: 09/24/2018] [Indexed: 01/02/2023]
Abstract
Background The endoscopic placement of a self‐expandable metal stent (SEMS), an alternative to surgical bypass for the palliation of malignant gastric outlet obstruction (GOO), is commonly performed using a forward‐viewing endoscope with a wide therapeutic channel; however, due to limited availability, most Indian centers use a side‐viewing duodenoscope. We studied the feasibility and outcome of SEMS placement using side‐ and forward‐viewing endoscopes. Method Data of patients undergoing SEMS placement using side‐ and forward‐viewing endoscopes with a therapeutic channel for the palliation of malignant GOO presenting during a 5‐year period were analyzed retrospectively. Follow‐up data were obtained from records and telephonic interviews, and technical and clinical success, complications, and survival were evaluated. Results Of 114 patients (age 56.5 ± 11.6 years, 59 [52%] female), 90 (79%) and 24 (21%) underwent SEMS placement using side‐ and forward‐viewing endoscopes, respectively. Technical (89, 98.9% vs. 24, 100%, P = ns) and clinical success (84, 93.3% vs. 23, 95.8%, P = ns) and complication rate (3, 3.3% vs. 0, P = ns) between side‐ and forward‐viewing endoscopes were comparable. However, SEMS could be placed in a shorter time using a forward‐ rather than side‐viewing endoscope (21 min [inter‐quartile range 19.5–35] vs. 34 min [25–45], P = < 0.001). SEMS could be deployed successfully with a forward‐viewing endoscope in two patients in whom an initial attempt using side‐viewing endoscope failed. Gastric outlet obstruction scoring system (GOOSS) improved following stent placement (median 0, range 0–2 vs. 2, 0–3, P = 0.0001). The survival of patients undergoing SEMS placement using side‐ and forward‐viewing endoscopes was comparable. Conclusion Although side‐ and forward‐viewing endoscopes are equally effective for antroduodenal SEMS placement, the procedure can be performed faster using the latter.

Abstract
OPINION STATEMENT Pancreas cancer is a fourth-leading cause of cancer death in the USA and its incidence is rising as the population is aging. The majority of patients present at an advanced stage due to the silent nature of the disease and treatment have focused more on palliation than curative intent. Gastroenterologists have become integral in the multidisciplinary care of these patients with a focus on providing endoscopic palliation of pancreas cancer. The three most common areas that gastroenterologists palliate endoscopically are biliary obstruction, cancer-related pain, and gastric outlet obstruction. To palliate biliary obstruction, the procedure of choice is to perform endoscopic retrograde cholangiopancreatography (ERCP) with biliary stent placement. We tend to place covered self-expandable metal stents (SEMS) due to their longer patency and removability unless the patient has resectable disease. Pancreas cancer pain is a result of tumor infiltration of the celiac plexus and can be severe and poorly responsive to narcotics. To improve pain control, neurolysis of the celiac plexus has been performed for decades. Since 1996, neurolysis of the celiac area has been performed endoscopically by Endoscopic Ultrasound-Guided Celiac Plexus Neurolysis. This has proven to be as safe and effective as traditional non-endoscopic methods and has allowed the patients to decrease their narcotic use and improve their pain control. This should be done early on in the course of the disease to have maximal effect. Gastric outlet obstruction (GOO) occurs in approximately 15-20% of patients with pancreas cancer. Endoscopic palliation of GOO can be performed by placing uncovered metal enteral stents across the obstruction. This procedure has proven to be very effective in patients who have a short life expectancy (less than two to 6 months) while surgical bypass should be considered for patients with longer life expectancies because it offers better long-term symptom relief. This chapter will review the current literature, latest advancements, and optimal techniques for endoscopic palliation of pancreatic cancer.

Abstract
BACKGROUND AND AIM Self-expandable metal stents (SEMS) are used for non-resectable malignant gastric outlet obstruction (GOO). Studies of covered versus uncovered SEMS have yielded inconsistent results as a result of heterogeneity in design and patient population. We carried out a meta-analysis to compare covered and uncovered gastroduodenal SEMS. METHODS Using MEDLINE, Embase, and the Cochrane database, we identified 1624 patients from 13 prospective and retrospective studies that evaluated covered and uncovered SEMS for malignant GOO and were published until October 2016. We pooled data on SEMS dysfunction, technical and clinical success, and adverse events using the fixed-effect or random-effects model. RESULTS Compared with uncovered SEMS, covered SEMS did not show any significant difference in stent dysfunction risk (risk ratio [RR], 1.02; 95% confidence interval [CI], 0.79-1.32). A subgroup analysis of five randomized trials suggested a trend toward a lower dysfunction risk in covered SEMS (RR, 0.63; 95% CI, 0.45-0.88). Covered SEMS were associated with a lower occlusion risk (RR, 0.44; 95% CI, 0.28-0.68), but with a higher migration risk (RR, 4.28; 95% CI, 2.89-6.34). Technical and clinical success rates were comparable between the groups. Overall adverse events tended to be more frequent in covered SEMS (RR, 1.75; 95% CI, 1.09-2.83). CONCLUSIONS Outcomes of covered and uncovered gastroduodenal SEMS were comparable, although the lower dysfunction rate of covered SEMS observed in the analysis of randomized trials needs further investigation. Antimigration mechanisms for covered SEMS and identification of patients who can achieve longer patency from uncovered SEMS would help improve the outcomes of gastroduodenal SEMS.

Abstract
BACKGROUND Controversies exist about the optimal palliative management for patients with metastatic antropyloric adenocarcinoma. The aim of this study was to analyse the clinical outcome for patients with gastric outlet obstruction syndrome and metastatic antropyloric adenocarcinoma, who underwent endoscopic stenting or open gastrojejunostomy, in a prospective not randomised study. MATERIAL The clinical course and costs for 70 patients who had endoscopic stenting and for 30 patients who had in the same period a gastrojejunostomy for gastric outlet obstruction syndrome due to metastatic adenocarcinoma of the antropyloric region were prospectively analysed. RESULTS Hospital stay and time to resume oral feeding was shorter in patients who had endoscopic stenting (p < 0.05). Overall costs for endoscopic stenting were lower than those for gastrojejunostomy (11,000 versus 21,000 euros). Comparing patients who survived more than 6 months, costs between endoscopic stenting and gastrojejunostomy were similar (21,000 versus 22,000 euros). CONCLUSIONS Endoscopic placement of metallic stents offers an effective therapy in patients with advanced primay adenocarcinoma of the antropyloric region and poor general conditions. In patients with longer life expectancy, surgical gastroenterostomy has still a major role. In contrast to previous reports, costs for endoscopic stenting are similar to those of gastrojejunostomy in patients with longer life expectancy. Laparoscopic gastrojejunostomy has the theoretical advantage to reduce these costs with a less invasive procedure. Results for endoscopic stenting have improved significantly in recent years.

Abstract
PURPOSE OF REVIEW Malignant gastric outlet obstruction (GOO) is a debilitating complication of cancer associated with a poor prognosis. The primary aim in the management of malignant GOO is usually palliation starting with the reinstitution of luminal patency with either surgical bypass or enteral stenting. These traditional modalities, however, have important limitations. Endoscopic bypass is a novel approach to GOO and may be an ideal technique, in which a sustained bypass can be created through a minimally invasive approach. The goal of this review is to describe the technical aspects as well as the clinical data of endoscopic bypass. RECENT FINDINGS A review of this novel technique is timely given recent developments of several accessories and techniques that allow for safer and easier endoscopic bypass including the advent of the lumen apposing stent, a specialized double-balloon enteric tube, the EUS-assisted technique, and the natural orifice transluminal surgery approach. In addition, accumulating and promising data have emerged supporting the endoscopic approach to gastric bypass. SUMMARY Endoscopic bypass is a novel and developing field of therapeutic endoscopy with improving technique and promising clinical data. This review will help to shed light on the current status and future direction of this intricate endoscopic modality.

Abstract
AIM: To provide an overview of the clinical outcomes of self-expandable metal stent (SEMS) placement for malignant gastric outlet obstruction (MGOO).
METHODS: A systematic literature search was performed in PubMed of the literature published between January 2009 and March 2015. Only prospective studies that reported on the clinical success of stent placement for MGOO were included. The primary endpoint was clinical success, defined according to the definition used in the original article. Data were pooled and analyzed using descriptive statistics. Subgroup analyses were performed for partially covered SEMSs (PCSEMSs) and uncovered SEMSs (UCSEMSs) using Fisher’s exact test.
RESULTS: A total of 19 studies, including 1281 patients, were included in the final analysis. Gastric (42%) and pancreatic (37%) cancer were the main causes of MGOO. UCSEMSs were used in 76% of patients and PCSEMSs in 24%. The overall pooled technical success rate was 97.3% and the clinical success rate was 85.7%. Stent dysfunction occurred in 19.6% of patients, mainly caused by re-obstruction (12.6%) and stent migration (4.3%), and was comparable between PCSEMSs and UCSEMSs (21.2% vs 19.1%, respectively, P = 0.412). Re-obstruction was more common with UCSEMSs (14.9% vs 5.1%, P < 0.001) and stent migration was more frequent after PCSEMS placement (10.9% vs 2.2%, P < 0.001). The overall perforation rate was 1.2%. Bleeding was reported in 4.1% of patients, including major bleeding in 0.8%. The median stent patency ranged from 68 to 307 d in five studies. The median overall survival ranged from 49 to 183 d in 13 studies.
CONCLUSION: The clinical outcomes in this large population showed that enteral stent placement was feasible, effective and safe. Therefore, stent placement is a valid treatment option for the palliation of MGOO.

Abstract
BACKGROUND Malignant gastric outlet obstruction (GOO) leads to malnutrition and limits quality of life. Gastrojejunostomy has been the traditional treatment for GOO. Recently, the results of releasing duodenal obstruction with self-expandable metal stents (SEMS) have been encouraging. METHODS After the exclusion of 13 patients with gastrojejunal or jejunal strictures and 1 patient with intraabdominal lymphoma, the authors palliated the malignant GOO in 104 patients with 130 SEMS at a single center during the years 1999-2007. RESULTS The GOO was caused by pancreatic (n = 51), gastric (n = 24), duodenal (n = 7), biliary (n = 5), and other (n = 17) malignancies. Of the 104 patients, 76 (73%) did well with only one enteral stent placement, 21 (20.2%) required two stent placements, 4 (3.8%) required three stent placements, and 1 required four stent placements. The median dysphagia score was 0 before stenting and 2 after treatment (p < 0.001). Immediate failure occurred after 10 procedures (7.7%). Among the 104 patients, 6 (5.8%) died of stent placement-related reasons. Complications occurred for 13 patients (12.5%). The median hospital stay was 3 days, and the overall survival time was 62 days (range, 1-933 days). Of 11 patients with concomitant biliary obstruction and GOO, 10 (91%) underwent successful enteral and biliary stent placement within the same session. Of 15 patients experiencing jaundice after enteral stent placement, 6 (40%) underwent endoscopic biliary drainage successfully. CONCLUSION Enteral stenting is a safe and effective way to treat GOO. Gastrojejunostomy should be preserved for cases in which endoscopic stenting is not successful or possible.

Abstract
OBJECTIVES Previous studies reported comparable stent patency between covered self-expandable metallic stents (SEMS) and uncovered SEMS (UCS) for palliation of malignant gastric outlet obstruction (GOO). The aim of this study was to evaluate the efficacy and safety of the newly developed WAVE-covered SEMS (WCS), which has an anti-migration design, compared with UCS in gastric cancer patients with symptomatic GOO. METHODS A total of 102 inoperable gastric cancer patients with symptomatic GOO were prospectively enrolled from five referral centers and randomized to undergo UCS or WCS placement. Stent patency and recurrence of obstructive symptoms were assessed at 8 weeks and 16 weeks after stent placement. RESULTS At the 8-week follow-up, both stent patency rates (72.5% vs. 62.7%) and re-intervention rates (19.6% vs. 19.6%) were comparable between the WCS and the UCS groups. Both stent stenosis (2.4% vs. 8.1%) and migration rates (9.5% vs. 5.4%) were comparable between WCS and UCS groups. At the 16-week follow-up, however, the WCS group had a significantly higher stent patency rate than the UCS group (68.6% vs. 41.2%). Re-intervention rates in the WCS and UCS groups were 23.5% and 39.2%, respectively. Compared with the UCS group, the WCS group had a significantly lower stent restenosis rate (7.1% vs. 37.8%) and a comparable migration rate (9.5% vs. 5.4%). Overall stent patency was significantly longer in the WCS group than in the UCS group. No stent-associated significant adverse events occurred in either the WCS or UCS groups. In the multivariate analysis, WCS placement and chemotherapy were identified as independent predictors of 16-week stent patency. CONCLUSIONS WCS group showed comparable migration rate and significantly more durable long-term stent patency compared with UCS group for the palliation of GOO in patients with inoperable gastric cancer.

Palliation of malignant gastric outlet obstruction with simultaneous endoscopic insertion of afferent and efferent jejunal limb enteral stents in patients with recurrent malignancy. Surg Endosc 2015; 30:521-525. [PMID: 26091983 DOI: 10.1007/s00464-015-4234-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 05/10/2015] [Indexed: 12/17/2022]
Abstract
BACKGROUND Patients with prior pancreaticobiliary or distal gastric cancer treated surgically may have local anastomotic recurrence with obstruction of the afferent and efferent jejunal limbs. This report describes the efficacy and safety of simultaneous endoscopic insertion of self-expanding metal stents into the afferent and efferent jejunal limbs in patients with gastric outlet obstruction (GOO) of post-surgical anatomy for palliation of recurrent malignancy. METHODS Patients were identified from an endoscopic database at a specialized cancer center between September 2007 and March 2014. Technical success was defined as single-session insertion of afferent and efferent jejunal limb enteral stents. Clinical success was defined as immediate symptom relief and ability to advance diet. A durable response was defined as symptom relief of at least 60 days or until hospice placement or death. RESULTS Twenty-three patients were identified who underwent insertion of two 22-mm-diameter uncovered duodenal stents. Stent length varied from 60 to 120 mm. Stents were placed under endoscopic and fluoroscopic guidance. Three patients required balloon dilation to facilitate stent insertion. Average procedure time was 58.8 min (range 28-120). Technical success was achieved in 23/24 (96%) patients. Clinical success was achieved in 19/23 (83%) patients. Following initial stent insertion and prior to subsequent re-intervention, 11/19 (58%) patients had a durable response with a median duration of 70 days (range 4-315). Eight (42%) patients underwent subsequent re-intervention at a median of 22 days (range 11-315). Five patients had stent revision and were able to tolerate oral intake. Two patients had percutaneous endoscopic gastrostomy/jejunostomy insertion. One patient required surgical diversion for persistent obstruction. Complications included stent migration and post-stent insertion bacteremia due to food bolus obstruction. CONCLUSIONS Recurrent malignant GOO in patients with post-surgical anatomy treated with simultaneous endoscopic enteral stenting of afferent and efferent jejunal limbs has a high rate of technical and clinical success and low rate of complications and provides effective palliation.

Gastroenterol Res Pract 2014; 2014:309797. [PMID: 25610459 PMCID: PMC4290140 DOI: 10.1155/2014/309797] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2014] [Revised: 10/24/2014] [Accepted: 11/30/2014] [Indexed: 12/27/2022] Open
Abstract
The aim of our study is to compare the efficacy and safety of “outlet-shape” tailored stents with standard stents for the management of distal gastric cancer causing gastric outlet obstructions (GOOs) with varying gastric cavity shapes and sizes. To determine the shape and size of the GOOs, stomach opacifications were performed using contrast media before stenting. Two basic shapes of the residual cavity of the proximal GOO were observed: cup shaped or approximately cup shaped and funnel shaped or approximately funnel shaped. Other shapes were not found. In the GOO tailored group, the size and shape of the proximal ends of the tailored stent were suited for the residual cavity of the proximal GOO. The tailored stents included large cup-shaped stents and large funnel-shaped stents. GOO tailored covered stents led to less restenosis and reintervention rates compared to standard uncovered stents but with the same survival.

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
OBJECTIVE To compare the burden of total hospitalization as a ratio of survival of staging laparoscopy versus prophylactic bypass surgery in patients with unresectable periampullary adenocarcinoma. BACKGROUND Periampullary adenocarcinoma is an aggressive cancer with up to 35% of the patients at surgery found to be unresectable. Palliative prophylactic surgical bypass versus endoscopic stenting has been addressed by randomized controlled trials, but none reported on the burden of hospitalization. METHODS From a prospective database all patients with periampullary adenocarcinomas with a preoperative patent biliary stent and absent gastric outlet obstruction, but found unresectable during surgery, were analysed. They underwent a staging laparoscopy only versus prophylactic palliative bypass surgery. In-hospital days of the initial admission as well as all consecutive admission days during the remaining life span were compared both in absolute numbers and as relative impact. RESULTS The inclusion criteria were met by 205 patients. Of these 131 patients underwent a staging laparoscopy detecting metastases in 21 patients. In 184 laparotomies 54 patients underwent prophylactic palliative bypass surgery for unresectable disease. Median total in-hospital-stay in the Laparoscopy Group was 3 days versus 11 days in the Palliative Bypass Group (p = 0.0003). Patients with metastatic disease found during laparoscopy stayed 3.5% of the remaining life time in hospital vs. 10.0% (p = 0.029) in patients with metastatic disease who underwent bypass surgery. CONCLUSIONS Staging laparoscopy and early discharge in patients with metastatic peri-ampullary carcinoma resulted in reduced hospitalization, both in absolute number of days and as a rate of survival time.

Abstract
Endoscopic stents have evolved dramatically over the past 20 years. With the introduction of uncovered self-expanding metal stents in the early 1990s, they are primarily used to palliate symptoms of malignant obstruction in patients with inoperable gastrointestinal (GI) cancer. At present, stents have emerged as an effective, safe, and less invasive alternative for the treatment of malignant GI obstruction. Clinical decisions about stent placement should be made based on the exact understanding of the patient's condition. These recommendations based on a critical review of the available data and expert consensus are made for the purpose of providing endoscopists with information about stent placement. These can be helpful for management of patients with inoperable cancer or various nonmalignant conditions in the upper GI tract.

Abstract
BACKGROUND The authors report the final results of a prospective single-center randomized study whose aim was to compare the endoscopic placement of self-expandable stents with open surgical gastroenterostomy to relieve gastric outlet obstruction (GOO) in patients with advanced antropyloric adenocarcinoma. A systematic review of the medical literature from December 1999 to December 2011 was carried out to determine the results of endoscopic stenting in patients with GOO from unresectable primary cancer of the antropyloric region. METHODS In the prospective study, 18 patients with advanced adenocarcinoma of the antropyloric region and symptoms of GOO were enrolled. In 9 patients, self-expandable stents were placed, and in 9 patients, open surgical gastroenterostomy was performed. Patients were followed until death. Six hundred seventy-two patients with primary unresectable cancer of the antropyloric region and GOO syndrome who underwent endoscopic stenting were identified from the literature. RESULTS In the prospective study of 18 patients, there was no case of postprocedural mortality. Efficient gastric emptying resumed more quickly in patients who received stents, although 3 months after the procedures, there was no difference between the 2 groups. Mean crude survival was 258 days in patients who received stents and 283 days in those who underwent surgical gastroenterostomy (P = NS). In patients who underwent stent placement, there were 2 cases of stent migration and 2 cases of food impaction, which were resolved with endoscopy at a mean follow-up of 70 days. In the 672 patients from the literature, operative mortality and morbidity were very low. In prospective studies, complications related to stents were more common than previously thought. CONCLUSIONS Endoscopic placement of metallic stents offers an effective therapy in patients with advanced primary adenocarcinoma of the antropyloric region and poor general condition. In patients with longer life expectancies, the form of therapy should be chosen individually, considering that surgical gastroenterostomy has fewer complications in the medium term and that in patients with endoscopic stenting, very careful follow-up is required, with the possibility of new operative endoscopy in half of the patients.

Abstract
OBJECTIVES Patients with inoperable malignant gastric outlet obstruction (GOO) have been managed with self-expandable metal stents to improve oral intake. Recent studies have shown conflicting results on the capacity of self-expandable metal stents to restore food intake in the long term. This study evaluated the clinical effectiveness of enteral stent placement for GOO throughout the patients' lives. METHODS This was a multicentre, retrospective study with a long-term follow-up of 74 patients who underwent enteral stenting for symptomatic GOO. Data were collected to analyse improvements in oral intake for the patients' entire lives as assessed by the GOO scoring system (GOOSS), technical success, stent patency, complications, the need for reintervention, survival and the prognostic factors associated with stent patency. RESULTS Technical and clinical success was achieved in 100 and 97.2% of the patients, respectively. A total of 71/74 patients (95.9%) continued oral intake for the rest of their lives and 58/74 patients (78.4%) needed no further intervention until death. Solid food intake (GOOSS 2-3) continued until death in 47/74 patients (63.5%). The GOOSS score improved (P<0.001) during the follow-up compared with the baseline. The median survival and the mean stent patency were 8 and 76.6 weeks, respectively. The complication rate was 18.9%. Malignant stent reobstruction was observed in 7/74 patients (9.5%). A Cox multivariate analysis showed that duodenal location of the obstruction was the only independent factor associated with stent patency (hazard ratio=5.28; 95% confidence interval=1.14-24.45; P=0.033). CONCLUSION Enteral stenting in patients with unresectable GOO is safe and clinically effective. Ninety-five per cent of patients are able to resume oral intake for the rest of their lives, and the great majority remain free from further intervention. In approximately two-thirds of patients, solid food intake continues until death.

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
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 Gastroduodenal obstruction due to malignancy can be difficult to palliate. Self-expanding metal stents (SEMS) are gaining acceptance as an effective alternative to surgical bypass. METHODS Patients not suitable for surgical bypass, with complete gastric outlet obstruction as a result of malignancy, were offered palliation with SEMS from November 2004 to December 2008. The procedure was performed under fluoroscopic guidance and conscious sedation. Data were collected prospectively. RESULTS Seventy patients underwent SEMS placement (hepatobiliary and pancreatic malignancy, 44; antral gastric carcinoma, 19; other, seven). Follow-up was complete in 69 patients (99 per cent). Technical and clinical success rates were 93 and 95 per cent respectively. Median hospital stay was 2 (range 1-18) days, median survival was 1.8 (0.1-19.0) months, and 87 per cent had improved intake after SEMS placement, as determined by Gastric Outlet Obstruction Severity Score before and after stenting (P < 0.001). Complications included two episodes of minor bleeding. CONCLUSION The use of SEMS to alleviate complete malignant gastric outlet obstruction in patients with limited life expectancy is successful in re-establishing enteral intake in most patients, with minimal morbidity, no mortality and a short hospital stay.
